专利说明:

The invention relates to the field of hydropower, and in particular to power plants located in the sea or river course.
The purpose of the invention is to facilitate maintenance.
Haha. 1 shows a general view of a power plant in operating position; in FIG. 2 is a plan view of a power plant: in FIG. 3 section II — II of FIG. 2; in FIG. 4 is an enlarged section IV-IV of FIG. 2; in FIG. 5 - mounting block of a vertical cylindrical buoy.
A floating tidal power plant, installed in a sea or river stream, includes a pontoon in the form of a quadrangular frame 1, connected by a flexible connection 2 to an anchor 3, and a horizontal row of turbine generators 4, mounted on the frame 1 below it by means of vertical rods 5 .
In this case, the power plant is equipped with a horizontal hollow beam 6 immersed under the water level, a movable crane 7 having an arrow 8 and a rail 9 connected to the frame 1. moreover, turbine generators 4 are attached to the beam 6, the latter is rigidly connected to the lower ends of the rods 5, and the upper their ends are pivotally connected On one of the sides of the frame 1, the latter can be made rectangular, and the flexible anchor connection 2 and the rods 5 are connected to its long side. In addition, the power plant can be equipped with cables 10 and 11 and a vertical cylindrical buoy 12 having a cable entry 13 and a mounting block 14, the latter being located in the lower part of the buoy 12 and attached to the end of the flexible anchor connection 2 and cables 10 and 11 to the horizontal beam 6 and to the long side of the frame 1 on the side of the anchor 3, and the upper end of the buoy 12 is rigidly connected to the middle part
1813186 AZ '1813186 on the same side of the frame 1. The power plant may contain an additional pontoon' 15 having horizontal rods 16 and an additional cable 17, and the side of the frame 1 on the anchor side with a horizontal high chair 5, having positive buoyancy, with horizontal rods 16 additional pontoon 15 are located on the sides of the cylindrical buoy 12 and are attached to the protrusion 18, and the additional Y-cable 17 is attached to the mounting block 14, which can be pivotally mounted on the cylindrical buoy 12 and provided with ears 19 for fastening with a communication bracket 2 and owls 10, 11 and 17, and 15 can be installed blocking means 20 mounted on the inner surfaces of the short sides of the frame 1 for interaction with the ends of the horizontal beam 6 when it is lifted, additional vertical rods 20 20 and the second row of turbine generators 4 located on the other side of the horizontal beam 6 and attached to the latter using additional vertical rods 21. 25
The power plant can be equipped with an auxiliary cable 22 and mooring means 23, and the crane 17 - a working bridge 24.
A floating tidal power station is operating as follows:
Before installing the power plant in the sea or river flow, first, by means of flexible connection 2 and anchors 3, a cylindrical buoy 12 is installed, then a pontoon with turbines in a raised and fixed position is towed to some 35. The cables 10 and 11 are pre-attached to the mounting block 14, which during towing is located on the horizontal ledge 40 of the frame 1. Using the crane 7, the mounting block 14 is lifted, for example, by the free eye 19. When the power plant is towed into place, the mounting block 14 it is lowered along the cylindrical buoy 12 45 until it lies on its lower protruding part, after which the upper ring is lowered along the buoy 12, which is fastened to allow the mounting block 14 to rotate freely around the buoy 12, for example, 50 using nylon thrust The bearings and drive. Then, a cable is installed in the cable entry 13 and the frame 1 is attached to the upper part of the buoy 12. in this way, the entire floating power station can freely rotate in accordance with the direction of the flow, and turbine generators 4 generate electric current. when disconnecting the power station from the cylindrical buoy 12, the above operations are performed in the reverse order, but not until the turbine unit 4 is lifted and secured with a blocking device 20, and the cable connection attached to the upper part of the buoy 12 is disconnected. Depending on the depth, the turbine unit may have one or two rows of turbine generators 4.
In case of repair or for maintenance, the entire turbine unit rises, as shown by the dashed line in FIG. 3 or the solid line in FIG. 2. This maneuver is carried out first by unfolding flat and stopping all the turbine propellers, then the air is pumped into the buoyancy chambers in beam 6, after which it is possible to rotate the turbine unit hinged to the upper position and lock it using locking device 20. Using crane trolleys arrows 8, you can replace the faulty turbine generator 4 with a spare one, these works are carried out inside the frame 1. where there are no waves, which allows for repair work without wasting time waiting for the windless s. The power plant does not require auxiliary vessels or floating cranes for maintenance and repair, and also maintains its operability in tidal waves.
