Figure 8 is a partially enlarged view of a connection portion between a support body and a floating body.
    As shown in Figure 1, a support apparatus for a photovoltaic module 3 is provided according to the present description. The support apparatus for a photovoltaic module must be arranged on a surface of water and comprises: a support body 1 and a floating body 2, where the floating body 2 is connected to the support body 1 to provide buoyancy for the support apparatus. The photovoltaic module 3 is arranged on the support body 1 which is not used to provide buoyancy. The water surface above may be the surface of a lake, the surface of a river and the surface of a sea, or the equivalent.
    The difference compared to conventional technology is that in the embodiment of the present description, a connection function to provide a connection with the photovoltaic module 3 and a buoyancy function to provide buoyancy are separated. The support body 1 having the connection function can be used to provide only the connection with the photovoltaic module 3 and not to provide buoyancy. In the manufacturing and installation processes, it is unnecessary for the support body 1 to be watertight, so that the method of manufacturing the support body 1 can be greatly simplified, and that the manufacturing cost can be reduced. to be reduced. In addition, the floating body 2 provides only the buoyancy and does not need to serve as a connector, in which case it is unnecessary to provide a connection position on the floating body 2. Therefore, the method of manufacturing the floating body 2 can be simplified, thereby further reducing the cost of the support apparatus according to the present description.
    The support body 1 providing no buoyancy indicates that, in a case where the support body 1 is placed individually on the surface of the water, the gravity of the support body 1 may be greater than the buoyancy received by the support body 1. This means that the support body 1 does not provide buoyancy, in which case the support body 1 may be a metal component having a high density. Alternatively, in a case where the support body 1 is made of a light material such as plastic, the buoyancy received by the support body 1 may be greater than the gravity of the support body 1, and the support body 1 can be positioned above the surface of the water and not be in contact with the surface of the water. In this case, the support body does not participate in providing buoyancy.
    The embodiment of the present description does not exclude the technical solution also using the support body 1 to provide buoyancy. In practice, the support body 1 can help provide buoyancy. This means that the buoyancy received by the support body 1 being greater than the gravity of the support body 1 and that the support body 1 being in contact with the water surface is also an alternative solution of the support apparatus according to the present description, in which case, a load of the floating body 2 can be reduced, thereby reducing the volume of the floating body 2 and reducing the space occupied by an installed support apparatus.
    It should be understood that a principle of the present description is to provide separately the buoyancy function and the connection function. When manufacturing the support body 1, only a reliability of the connection of the support body must be taken into account. The fact that the support body is used to provide buoyancy may or may not be taken into account, and both cases are included in the present description. In this way, the design and manufacture of the support body 1 can be substantially simplified, and the support body 1 is not necessarily made of a material or structure whose gravity is greater than the buoyancy received. In addition, only the buoyancy function must be considered in the design and manufacture of the floating body 2. The floating body 2 may have a cavity structure or may be made of a light material such as foam or plastic, which is determined according to the actual conditions.
    More importantly, both a front surface and a rear surface of the photovoltaic module 3 arranged on the support body 1 can be used for the generation of photovoltaic energy. That is, both surfaces of the photovoltaic module 3 can be used for the generation of photovoltaic energy. The support body 1 is provided with a plurality of through holes A extending through the support body 1 in a vertical direction. In use, the sunlight passes through at least the several through holes A, is incident on a surface of water and reflected by the water surface, and is incident on the rear surface of the photovoltaic module 3 through the several through holes A so that the rear surface of the photovoltaic module 3 can also receive sunlight. In this case, both the front surface and the rear surface of the photovoltaic module 3 can realize the generation of photovoltaic energy. The use of sunlight is increased, and the amount of photovoltaic power generation can be increased. In addition to the through holes A, the sunlight can also be reflected by a water surface between the support body 1 and the floating body 2 which is not covered by the photovoltaic module 3, and is incident on the rear surface photovoltaic module 3 for the generation of photovoltaic energy.
    The "front surface" above indicates a surface of a photovoltaic panel of the photovoltaic module 3 which faces the sunlight, and the "rear surface" indicates a surface opposite to the front surface of the photovoltaic panel. Generally, especially when used on land, the floor is not reflective, and the back surface of the photovoltaic panel can not receive light. Therefore, the conventional photovoltaic power generation device generally generates energy using only the front surface of the photovoltaic module 3 which absorbs sunlight. The "vertical" above, which is an axial direction of the through-holes A, is not necessarily the absolute vertical direction, and may also be a direction at a certain angle to the absolute direction, since the Sunlight can reach the water surface through the through holes A, be reflected and incident on the back surface of the photovoltaic module 3 through the through holes A.
    In addition to facilitating the generation of energy by the two surfaces of the photovoltaic module 3, the heat exchange between the photovoltaic module 3 and the surface of the water can also be increased by using the through holes A, improving thus the cooling of the photovoltaic module 3 and reducing a service temperature of the photovoltaic module 3, the efficiency of the photovoltaic energy generation can thus be increased.
    In another embodiment, as shown in FIG. 1a, a wavy line in FIG. 1 represents the surface of the water. In use, the support body 1 can be completely immersed in the water due to its own gravity and a pressure of the photovoltaic module 3. In this case, the sunlight can reach directly the surface of the solar module. water, to be reflected by the surface of the water, and to be incident on the rear surface of the photovoltaic module 3 so as to increase the amount of sunlight reflected and to improve the efficiency of the energy generation of the rear surface Furthermore, the heat exchange between the photovoltaic module 3 and the surface of the water can be further improved. In this case, the support body may or may not be provided with through holes A above. In the present description, the diagram where the through holes A are provided is preferable, because on the one hand, a weight of the support body 1 can be reduced to reduce the buoyancy demand, on the other hand, the immersion of the body support 1 in the water is facilitated.
    In addition, the support body 1 and / or the floating body 2 may be provided with a reflective coating. A reflectivity of the reflective coating is greater than the reflectivity of the surfaces of the support body 1 and the floating body 2, so that the amount of reflected sunlight can be increased, so as to further increase the amount of photovoltaic energy generated. The reflective coating is not limited to the upper surfaces of the support body 1 and the floating body 2. The reflective coating can be provided on the side surfaces of the support body 1 and the float body 2, according to a real-life condition. .
    In a specific diagram, the support body 2 may have a frame structure, as shown in FIGS. 2 and 3, the support body 1 may comprise a support frame 11, and several reinforcing beams 12 may be arranged in the support frame 11 so as to improve the strength of the support body 1. The number and arrangement of the reinforcement beams 12 above are not limited in the present description. The through holes A above may be formed between the reinforcing beams 12 and / or between the reinforcing beams 12 and the edge beams of the support frames 11. Alternatively, the support body 1 may have a plate shape , and the through holes A above may be formed on the support body 1 by a method such as cutting. In this case, the technical effect of facilitating the reflection of sunlight can also be achieved.
    The through holes A may be circular holes, square holes, triangular holes, or holes of other irregular shapes, to the extent that sunlight can reach the surface of the water through the holes. A through, be reflected and be incident on the rear surface of the photovoltaic module 3 through the through holes A.
    The frame structure of the support body 1 above can be formed by separate components, and can be formed by combining the edge beams and the reinforcing beams 12 by clamping, assembling, welding, or using Alternatively, the frame structure of the support body 1 above may be an integrated structure. This means that the support frame 11 and the reinforcing beams 12 can be formed in one piece by a process such as one-piece injection molding or intaglio molding. In the case of intaglio molding, a first process hole 15 may be retained on the support body 1. In use, the first process hole 15 may be sealed with a sealing component to prevent leakage. entry of water or air. Of course, considering that the support body 1 may not be used to provide buoyancy, the first process hole 15 may not be sealed.
    The rim beam of the support frame 11 may be provided with a reinforcing structure 111 so as to improve the strength of the support frame 11. The reinforcement structure 111 may be a reinforcing rib mounted on the support beam 11. edge of the support frame 11 by welding after the support frame 11 is manufactured. Alternatively, the reinforcement structure 111 and the support frame 11 may also be formed in one piece, in which case the reinforcement structure 111 may be a concave or convex structure arranged on the edge beam to enhance the resistance capabilities to the bending and twisting of the corresponding edge beam, thus protecting the support body 1 damage due to impact water and the equivalent.
    One of an upper surface and a lower surface of the support frame 11 may be provided with a positioning projection 112, and the other of the upper surface and the lower surface of the support frame. 11 may be provided with a positioning groove 113 corresponding to the positioning protrusion 112. During transport, a plurality of support bodies 1 may be stacked vertically, and the positioning protrusion 112 of one of two adjacent support bodies 1 can be inserted into the positioning groove 113 of the other of the two adjacent support bodies 1 so as to limit a relative displacement of the two support bodies 1, so that the movement of each of the support bodies 1 stacked during transport can be avoided, thus ensuring the stability of the support bodies 1 during transport.
    It should be understood that the positioning protrusion 112 and the positioning groove 113 may not be provided, and in this case, the support bodies 1 may be held in a net stack by means of location limiting components. such as ropes and plates limiting the location, to facilitate transportation.
    As regards Figure 2, four angles of the support frame 11 may be provided with first connection positions 13 to facilitate the fixed connection between the support body 1 and the floating body 2 or between two support body 1. The frame 11 is further provided with a second connection position 14 for connection to the support assembly 4 for fixing the photovoltaic module 3.
    With reference to FIGS. 4 and 5, the support assembly 4 may comprise a first support plate 41, a second support plate 42 and a fixation frame 43, where the first support plate 41 and the second support plate 41 support 42 can be arranged on two opposite sides of the support body 1, and are attached to the second connection positions 14. In addition, one of the first support plate 41 and the second support plate 42 is higher and the other is lower, in which case the fixing frame 43 arranged on the two support plates can be inclined at a predetermined angle with respect to the horizontal surface, so that the photovoltaic module 3 arranged on the fixing frame 43 can better receive sunlight, thus guaranteeing the yield of photovoltaic energy generation. The "predetermined angle" above is not limited here, it is related to the latitude, longitude and sunlight angle of the sun where the photovoltaic module is installed, and can be set by the skilled person according to the actual situation. It should be understood that because of the above predetermined angle, the sunlight can pass through the through holes A arranged on the support body 1, be reflected and incident on the rear surface of the photovoltaic module 3.
    In use, whether the support body 1 is totally immersed in the water or not, the photovoltaic module 3 mounted and fixed through the support assembly 4 must be maintained at a certain safety distance from the surface of the water, to avoid the immersion of the photovoltaic module 3 by the water because of the winds or the swell. The above "safety distance" can be set depending on the actual condition of the water surface above which the photovoltaic module 3 is mounted. If the surface of the water is calm, the above safety distance may be lower, and if the waves are frequent, the above safety distance may be higher.
    Regarding Figures 6 and 7, the floating body 2 may comprise a housing which comprises a sealed buoyancy cavity. The housing may be formed by intaglio molding. A second conserved process hole 23 generated in the blow molding process can be sealed using a sealing component to prevent water from entering the float body 2 so that the buoyancy provided by the float 2 is weakened. or lost.
    The floating body 2, in addition to functioning as a buoyancy unit, can also be used to provide a maintenance channel, thereby facilitating the maintenance of the photovoltaic module 3. Therefore, the floating body 2 must also have some resistance to avoid damage due to external pressures.
    This is why the floating body 2 can also be provided with a support structure so as to support an upper wall (a wall on which people can walk) of the floating body 2. As shown in FIG. 7 in the embodiment of the present description, the support structure may be a tapered support structure 21, one end of which has a larger diameter may be connected to a bottom wall of the floating body 2, and one end with a larger diameter. small diameter can be connected to a bottom wall of the floating body 2 so as to support the upper wall. Alternatively, the support structure may also be a reinforcing plate, a reinforcing rib or other forms of support components arranged in the floating body 2 and connected between the top wall and the bottom wall.
    In addition, an anti-slip structure 24 may also be arranged on an upper surface of the floating body 2 so as to increase a coefficient of friction of the upper surface of the floating body 2, thus increasing friction between the staff foot and the upper surface of the floating body 2, so that it is possible to prevent the staff from slipping when walking on the floating body 2.
    Four angles of the floating body 2 may be provided with floating body connection positions 22 to be connected to the support body 1. As shown in FIG. 8, the first connection position 13 of the support body 1 and the connection position of the floating body 22 of the floating body 2 can be stacked, and connected using bolts, pins and other forms of connectors, to connect the support body 1 with the floating body 2. In addition to the embodiment shown in Figure 8, other ways can be adopted to connect the support body 1 and the floating body 2. For example, a connector can be directly attached to one of the first connection position 13 and the position 22. The connector passes through the other of the first connection position 13 and the floating body connection position 22 so as to connect and secure the body of the body. support 1 with the floating body 2.
