    Shut-off facility
    The invention relates to an underwater device tunnel closure arrangement which is located in the hull of a water craft, below a water craft water boundary having a certain diameter and an inner surface, comprising a closure element at least partially covering the device tunnel diameter which is removably mounted.
    Prior art
    In water craft, as in other water structures, such as drilling rigs or similar structures, propellers are often used to position or control the water craft or water structure in addition to the actual propulsion system. For example, such propeller propulsion devices may be so-called. bow or skeg propeller devices. Kick h equipment is usually installed in the transverse tunnels of the ship, so called. potkuritunneleihin. Propeller units require maintenance, repair, or replacement with new equipment, which can be done on site or by removing the propeller unit from the water craft or drilling rig for operations. These operations can be done, for example, by docking a watercraft, which is cumbersome and time consuming in addition to the actual operation. Smaller maintenance and repairs can be done with the help of the diver, but it is understandable that underwater work has significant limitations in terms of both working conditions and the work to be performed.
    In order to facilitate the operations, the propeller tunnel has been drained of water, which first required welding of the fixed support structure to the outer edges of the propeller tunnel. The fixed support structure is then fitted with a shield or cover under water, after which the propeller tunnel is emptied of water. First of all, this has required very demanding underwater welding work, after which the propeller tunnel must be closed and emptied of water. In addition, fixed welded structures make it difficult, for example, to get in and out of the propeller tunnel with the necessary tools, and also to move propeller equipment or parts thereof into or out of the tunnel.
    This may be another type of device, where the propeller tunnel may be called a device tunnel.

    Special Explanatory Note
    In Figure 1, the water craft is designated by the reference WC. The water boundary of the water craft is indicated by the reference WL and the underwater equipment tunnel PT on the water craft, which in this embodiment is represented by the so-called. potkuhtunnelina. Hereinafter, the device tunnel is called the propeller tunnel. Propeller tunnel has been given
    20185494 prh 31 -05-2018 has a diameter D1 and is substantially cylindrical, with the propeller tunnel having a substantially cylindrical inner surface S. In this example, a rotatable propeller P with propeller P, e.g. Azipod hardware with 360 ° swing direction. It is understood that the kicking device and its arrangement may be other than that shown in the figure. The tunnel in question may have other or different types of equipment, so the term propeller tunnel must be broadly understood. Opposing orifices of the kick tunnel PT are indicated by reference marks PT1 and PT2. The closure arrangements to be mounted in the opposing orifices are indicated by reference numerals 11 and 12. The closure arrangements may be in accordance with each embodiment of Figures 2A and 2B or as shown in Figures 3A and 3B, as required.
    In the following, the structure of the closure arrangement embodiments and the associated installation will be described.
    Figures 2A and 2B show an embodiment of the closure arrangement 1. Figures 4A 15 and 4B show cross-sections of the circumference of the closure arrangement. The fastening elements 22, the support elements 32, and the clamping elements 33, which will be described in more detail below, are spaced apart at the arch portion 21, as indicated by dashed lines in Figures 4A and 4B.
    The closure arrangement 1 comprises a frame element 2 formed of a circular arc portion 21 of rigid mate20 provided with spaced spaced fastening elements 22 which allow the arc to be secured directly to the inner surface S of the kick tunnel PT. of the threaded bolts 222 which are twisted to provide fastening. Preferably, the fastening elements 22 are arranged at equal intervals on the arch portion 21 to provide a uniform fastening.
    The frame element 2, i.e. the arch part 21, is fixedly supported by a fitting element 3. The fitting element 3 may be formed of a circular edge portion 31 which is slidably mounted and supported by a support element 32 disposed at a certain distance on the arch part 21. Preferably, the support elements 32 comprise a sleeve 321 attached to an arch portion 21 having a spindle 322 movable in a sleeve 321 attached to a barrel portion 31. This allows the barrel portion 31 to be fitted against and away from the inner surface S of the propeller tunnel PT.
    20185494 prh 31 -05- 2018
    Tightening of the housing member 31 against the inner surface S of the propeller tunnel PT is effected by the clamping elements 33 (Fig. 4A). Preferably, the clamping elements 33 consist of threaded bushings 331 fixed to the arc portion at certain intervals 21 and threaded bolts 332 fitted thereto, which are rotated to allow the insert portion 31 to be tightened against the inner surface S of the choke tunnel PT.
    The frame element 2 and the fitting element 3 form a support structure for the closure arrangement, which is thus circular.
    The sealing element 4 of flexible material, in this embodiment by way of example, comprising a protective cover 40, is pivoted about the peripheral portion 31 to provide a closure in the form of a curved portion 21. The cover 40 has a circular shape and is preferably provided with a circumference 41 to better retain it in place when mounted around the panel 31. Further, the periphery of the protective cover 40 is preferably provided with a resilient sealing element 5 which is intended to be positioned between the flat portion 31 and the protective cover 40 so as to secure the sealing against the inner surface S of the propeller tunnel PT. Alternatively, the sealing element 5 may be mounted on the body portion 31. The protective cover 40 may be secured to the frame element 2 and / or the fitting element 3, for example by the thread 7 shown in Figures 4A and 4B or the like.
    The cover 40 is provided with aeration means 42. The aeration means is preferably an aeration valve 20 (Figures 1-3B).
    The cover 40 is preferably provided with a buoyancy means 43 such that the closure arrangement 1 can be displaced underwater into the underwater propeller tunnel PT as a whole in the desired position. The buoyancy means 43 is preferably an air pocket 430 provided with an aeration device 44, preferably an air vent valve. The buoyancy means may also well be some kind of float or other means for making the closure arrangement float in water.
    For example, the flexible sealing element 5 may be so-called. sealing rubber or other similar material. The frame element 2 and the fitting element 3, as well as the components mentioned above, may be, for example, stainless steel, aluminum, or other similar rigid material. Preferably, the materials are suitable for use in underwater environments and for land storage.
    Figures 3A and 3B show another embodiment of the closure arrangement 1. Figures 4A and 4B are cross-sectional views of the periphery of the closure arrangement. Above, the patterns
    20185494 prh 31 -05- 2018
    2A and 2b, the fastening elements 22, the support elements 32, and the clamping elements 33 are distributed over the arch portion 21 at different distances, as indicated by dashed lines in Figures 4A and 4B.
    The main difference with respect to the embodiment described in Figures 2A and 2B above is that the support structure of the closure arrangement, which thus comprises a frame element 2 and a fitting element 3, is in the form of a circular segment. To securely mount the circular segment-shaped arch portion 2 in the propeller tunnel PT, the ends of the arc portion 21 are connected by a transverse support 6 to stabilize the support structure. The protective cover 40 is thus preferably also in the shape of a corresponding circular segment. This 10 preferably also applies to the aforementioned thickener 41 and the sealing element 5.
    Following is a brief description of the installation of the closure arrangement and its removal from the kick tunnel with reference to Figures 1-4B and the above construction and installation description.
    First, a support structure 15 corresponding to the size of the propeller tunnel PT, i.e. its diameter D1, is selected, i.e., the assembly of the frame element 2 and the fitting element 3, comprising an arch portion 21 having the above fastening elements 22 and a fitting element 3 having the support elements 32 and clamping elements 33 described above. Subsequently, a closure element 4 corresponding to the size of the support structure is selected, that is, a protective cover 40, preferably having a bore 41 and preferably also a sealing element 20 on the periphery. Thereafter, the flotation device 43, i.e. the air pocket 430, is filled with air through the aeration device 44, i.e. the aeration valve.
    The protective cover 40 may be attached to the frame element 2 and / or the fitting element 3, for example by the thread 7 shown in Figs. 4A and 4B or the like.
    Next, the (first) closure arrangement 11, which in the example shown in Fig. 1 comprises a circular (Figs. 2A and 2B) frame element 2, fitting element 3 and closure element 4, can be moved into water and introduced into the (first) mouth PT1 of the propeller tunnel. The closure arrangement 11 remains in the desired position such that the air pocket 430 at the upper edge 30 of the closure arrangement carries the closure arrangement 1 in water in a substantially upright position so that it is more easily fitted to the mouth of the propeller tunnel PT.
    When the closure arrangement 11 is fitted to the mouth of the propeller tunnel PT, preferably in an upright position, the support arrangement of the closure arrangement comprising the frame element 2 and the fitting element 3 can be secured to the inner surface S of the propeller tunnel PT as described above.
    20185494 prh 31 -05-2018 (Second) closure arrangement 12, which in the example shown in Fig. 1 comprises a circular segment (Figs. 3A and 3B) shaped frame element 2, fitting element 3, and closure element 4, is similarly introduced into the opposite (second) mouth PT2. After attachment, the protective covers 40 of each closure arrangement 11 and 12 are sealed against the inner surface S of the propeller tunnel PT as described above.
    Next, air is supplied to the space between the shut-off arrangements 11 and 12 of the propeller tunnel PT through the aeration means 42, i.e. the aeration valve. This provides a water-free working space WS at the top of the propeller tunnel PT, which extends from the top of the propeller tunnel to the bottom of the second closure arrangement 12 as shown in Figure 1. A passage AO is formed between the lower edge 12 of the second closure arrangement and the lower edge of the propeller tunnel to the working space WS. The closure arrangements are selected according to the type of workspace that is to be provided in the kick tunnel. Of course, a circular closure arrangement may also be used to partially close the propeller tunnel PT port by partially leaving the protective cover open, as indicated by the dotted line in Figure 2A.
    Thereafter, the necessary operations can be easily performed, for example, on the propulsion device PD or its propeller P.
    After the operations, the air is discharged from the working space WS through the aeration valves in the protective covers, and the closure arrangements 11 and 12 can be removed from the mouth openings PT1 and PT2 of the propeller tunnel PT and lifted back out of the water. The buoyancy means 43 facilitate the transport of the closure arrangements to the water surface.
    The solution of the invention provides simple means for operations in an underwater propeller tunnel in an anhydrous, work-friendly and safe environment.
    The drawings and the related description are merely intended to illustrate the basic idea of the invention. Details such as, for example, a frame element, a fitting element and a sealing element with additional components may vary within the scope of the appended claims.
