DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0026] As Figure 1As shown, the utility model provides an embodiment: a water surface power station overhauling platform, including ship body 1 and setting on the ship body 1 embrace stake mechanism 2, lift 3 and overturn mechanism 4, embrace stake mechanism 2 is used for the ship body 1 after lift 3 is lifted (maximum can be lifted to 8 meters), face the danger of tilting and falling, embrace stake mechanism 2 is fixed on the deck of ship, its claw stretches out from the deck, embraces the cement column 8 for fixed assembly on water surface, its main body and the angle of ship, the extension length can be fixed when adjusting to the appropriate position, lift 3 is installed with operation frame, through lift 3, operation frame is lifted to high altitude until the position required by overhauling, overturn mechanism 4 includes frame 5, traction hoist 6 and hinge 7, frame 5 is fixed on the ship body 1 and is connected with the bottom of lift 3 through hinge 7, traction hoist 6 is set on the beam of frame 5, and chain is connected with the side of lift 3.

[0027] In order to make the system have good passability on the water surface, the embrace stake mechanism 2 can be retracted on the deck of the ship during the ship's travel, and does not exceed the plane range of the ship. The lift 3 is laid down on the deck of the ship body 1 during standby or travel, and the total height is about 60 cm above the deck. When the lift 3 is in the retracted and laid-down state, the embrace stake mechanism 2 is retracted above the deck, and this state is as shown in Figure 2 ; After reaching the vicinity of the work area, the ship is adjusted to the position where it needs to be parked, the embrace stake mechanism 2 is extended, the length and angle are adjusted so that the embrace stake claw 207 embraces the cement column 8 standing on the water surface (the cement column 8 is originally standing on the water surface to support the solar module column, and is not the content of the design), and we lock the embrace claw extension fixing bolt and the angle fixing bolt, and this state is as shown in Figure 3 ; On the basis of Figure 3 , we start the electric hoist of the overturning machine to overturn the laid-down lift 3 to the standing state, and fix it with a bolt, and this state is as shown in Figure 4 ; On the basis of Figure 4 , we start the extension button of the lift 3 to adjust the lift 3 to the height we need, and this state is as shown in Figure 5 .

[0028] The frame 5 of the overturn mechanism 4 is welded on the deck of the ship body 1, the traction hoist 6 is fixed on the frame 5 with a bolt, and when it is powered on, the lift 3 rotates around the hinge 7 from the laid-down state to the standing state. That is, from Figures 3 to 4 state.

[0029] In this embodiment, as shown in Figure 6 and Figure 7As shown, the pile-holding mechanism 2 includes a square tube 201, a rotating shaft 202, a sliding sleeve 206 and a pile-holding claw 207; the square tube 201 is fixed transversely on the deck of the ship body 1; the lower part of the rotating shaft 202 is fixedly connected to the square tube 201; the sliding sleeve 206 is connected to the upper part of the rotating shaft 202, so that the sliding sleeve 206 rotates relative to the rotating shaft 202, and is fixed in the upper, inner and lower directions of the rotating shaft 202 through the plane bearing 203, the copper sleeve 204 and the cover plate 205; the pile-holding claw 207 is inserted into the sliding square hole of the sliding sleeve 206, and can slide linearly in the middle of the sliding sleeve 206; the front opening of the pile-holding claw 207 holds the cement column 8 through linear and rotary operation, and then the opening end is buckled by the swing arm 208, finally the reverse loosening is prevented by the check device 209, so as to lock the cement column 8 between the pile-holding claw and the swing arm 208, and then the rotation fixing screw of the sliding sleeve 206 and the linear motion fixing screw of the pile-holding claw 207 are fixed by bolts, so that the ship body 1 and the whole maintenance platform are fixed and cannot move horizontally and cannot be tilted, and are used for the maintenance of solar components, supports, combiner boxes and other field equipment of the water surface photovoltaic power station.

[0030] The square tube 201 is provided with openings on the upper and lower surfaces at one end position, and the rotating shaft 202 is fixedly connected to the two opening surfaces by welding. The square tube 201 has two functions, one of which is to strengthen the rigidity of the ship in the transverse direction. If the rotating shaft 202 is directly welded to the deck of the ship body 1 without the square tube 201, the deck is mostly made of steel plate and is relatively thin, within 20 mm. If the ship has the possibility of tilting, the pile-holding claw 207 will have a larger moment, and the pile-holding claw will finally transmit this moment to the rotating shaft 202 and the deck steel plate fixedly connected with the rotating shaft 202, which may cause the deck to deform, thereby causing the elevator 3 at a high position to be inclined, causing danger. The square tube 201 greatly strengthens the rigidity of the deck and is not easy to deform, and the square tube 201 is provided with openings on the upper and lower surfaces, and the rotating shaft is welded to the two surfaces in contact with the square tube 201, thereby strengthening the firmness of the welding.

[0031] In the preferred embodiment, as Figure 8As shown, a flange is provided inside the copper sleeve 204 to reduce the friction when the sliding sleeve 206 rotates. The sliding sleeve 206 includes an upper iron plate 211, a lower iron plate, a first channel steel 212, a second channel steel 213, and a single third channel steel 214, which are connected by bolts and gaskets of appropriate thickness to form the sliding sleeve 206. The first channel steel 212 and the second channel steel 213 are butt-welded and fixedly connected, and through holes are machined. The through holes pass through the flanged copper sleeve 204, and the copper sleeve 204 is connected to the first channel steel 212 and the second channel steel 213 by bolts through the flange. It is equivalent to the copper sleeve 204 being embedded in the first channel steel 212 and the second channel steel 213. The groove direction of the third channel steel 214 is opposite to that of the second channel steel 213, and a four-sided square hole is formed between the third channel steel 214 and the second channel steel 213 by the upper iron plate 211 and the lower iron plate. The ball bearings 215 are secured to all four sides of the square hole of the sliding sleeve 206 with nuts, allowing the pile gripper 207 to move freely within it. In addition, a plate-shaped anti-rotation device 210 is provided on the square tube 201. One side of the anti-rotation device 210 is in contact with the lower iron plate, and the other side is arc-shaped. An anti-rotation arc groove 216 is machined on the anti-rotation device 210. The arc angle of the anti-rotation arc groove 216 is adapted to the sliding sleeve 206. After being tightened by screws passing through the anti-rotation arc groove 216, the sliding sleeve 206 stops rotating.

[0032] In a preferred embodiment, such as Figure 9 As shown, the pile clamping device includes interconnected rods and claws. The rods are inserted into the square holes of the sliding sleeve 206. The claws are equipped with a swing arm 208 and a check device 209. A through hole is provided on the edge of the claw near the sliding sleeve 206, and a bearing 219 is installed in the through hole. The swing arm sleeve 218 is fixed to the claw by passing a screw 217 and a matching nut through the bearing 219. It cannot move up and down, but it can rotate left and right around the screw 217. The swing arm 208 is in the shape of a "U" and is welded to the swing arm sleeve 218. When it is necessary to clamp the pile, the swing arm 208 is rotated to the F-port open state. After the F-port clamps the cement pile, the swing arm 208 is rotated to the F-port closed state, and the check device 209 locks the swing arm 208 so that it cannot be reversed.

[0033] In a preferred embodiment, such as Figure 10 As shown, the check valve 209 includes a check seat 221 and a check tongue 220. One end of the check tongue 220 is provided with a shaft hole, and it is fixed to the check seat 221 through a rotating shaft on the shaft hole. A torsion spring 222 is provided on the rotating shaft. Figure 10 The left diagram shows the structure of the pile gripper 207 in its open state. In the diagram, the check valve 221 is fixed to the side of the pile gripper 207. One end of the check tongue 220 has a small hole that passes through the shaft on the check valve 221. Under the elastic action of the torsion spring 222, the check tongue 220 is in an upright state. When the swing arm 208 moves from right to left, the right side of the check tongue 220 is compressed by the swing arm 208, causing the check tongue 220 to rotate counterclockwise.Figure 10 When the swing arm 208 is disengaged from the right side (which becomes the upper side at this time) of the check tongue 220, the check tongue 220 cannot be pressed, and the check tongue 220 is popped up under the action of the torsion spring 22222 until Figure 10 The other side of the check tongue 220 abuts against the swing arm 208, and the check tongue 220 no longer rotates, and since one side of the check tongue 220 abuts against the swing arm 208, the swing arm 208 cannot rotate to the right, thereby realizing the one-way rotation of the swing arm 208. The mouth becomes a mouth-shaped, and the cement column 8 is held.
