[0063] Optionally, the sliding mechanism 500 and the second locking rod 330 are arranged in a one-to-one correspondence, and the number of the sliding mechanism 500 and the second locking rod 330 may be the same as the number of the first locking rod 310, or may be less than the number of the first locking rod 310. When the number of the sliding mechanism 500 and the second locking rod 330 is the same as the number of the first locking rod 310, the sliding mechanism 500, the second locking rod 330 and the first locking rod 310 are arranged in a one-to-one correspondence. For example, referring to Figures 2 to 4 As shown, when there are six first locking rods 310, six driving grooves 410, and six strip holes 210, there are also six second locking rods 330, six avoidance grooves 350, six sliders 240, and six slide seats 230.

[0064] Optional, see Figure 1 As shown, the lifting mechanism 110 includes a lifting drive member and a driving rod, one end of the driving rod is connected to the cover plate 200, and the other end of the driving rod is connected to the lifting drive member, the lifting drive member is connected to the barrel body 100, and the lifting drive member drives the driving rod to lift and move.

[0065] Further references Figure 1 As shown, the lifting mechanism 110 is arranged along the center line of the barrel body 100 , and the rising driving member is connected to the barrel bottom of the barrel body 100 .

[0066] The lifting drive member can be selected according to the use requirements, for example, the lifting drive member is a compression spring, one end of the compression spring is connected to the bottom of the barrel body 100, and the other end of the compression spring is connected to the driving rod, and the compression spring provides a force for the driving rod to move away from the bottom of the barrel. When the lifting drive member is a compression spring, no additional power is required.

[0067] For another example, the lifting driving member is a linear motor, and the linear motor drives the driving rod to lift and move.

[0068] In order to protect the lifting mechanism 110 and prevent the lifting mechanism 110 from affecting the support frame 250, the lifting mechanism 110 also includes a hollow cylindrical structure, one end of which is fixedly connected to the barrel body 100, and part of the rising drive member and the drive rod are arranged in the hollow cylindrical structure, and the other end of the hollow cylindrical structure is for the drive rod to extend.

[0069] Optionally, in order to facilitate maintenance by maintenance personnel, the cover plate 200 is rotatably connected to the end of the driving rod, that is, the cover plate 200 can rotate around its own axis relative to the barrel body 100. Alternatively, the driving rod is rotatably connected to the rising driving member, the driving rod can rotate relative to the barrel body 100, and the driving rod can drive the cover plate 200 to rotate relative to the barrel body 100. When the maintenance personnel are working, they can inspect multiple parts to be inspected in the shell structure by rotating the cover plate 200, and the maintenance personnel do not need to move around the barrel body 100.

[0070] The operation process of the shell structure in the embodiment of the present application is as follows, wherein each part to be repaired is respectively installed on a corresponding support frame 250.

[0071] When the shell structure is in normal use, the cover plate 200 covers the barrel body 100 and is locked by the locking mechanism 300.

[0072] When the shell structure is being repaired, the adjustment plate 400 is rotated by the handle 420, and the driving slot 410 on the adjustment plate 400 drives each toggle portion 320 to move synchronously toward the center of the cover plate 200, and the toggle portion 320 drives the first locking rod 310 to move synchronously, and the first locking rod 310 retracts from the lock hole 120 into the cover plate 200. Under the lifting action of the lifting mechanism 110, the cover plate 200 rises, and the cover plate 200 lifts each part to be repaired away from the barrel body 100, so that each part to be repaired can be exposed to the eyes of the repair personnel, and the repair personnel only need to rotate the cover plate 200 to check each part to be repaired one by one.

[0073] In the process of the first locking rod 310 retracting into the cover plate 200, refer to Figure 5 As shown, the upper end of the second locking rod 330 initially abuts against the side wall of the first locking rod 310. As the first locking rod 310 moves, the avoidance groove 350 of the first locking rod 310 moves to the upper end of the second locking rod 330. Under the action of the elastic member 340, the second locking rod 330 rises and enters the avoidance groove 350. The lower end of the second locking rod 330 gradually disengages from the slider 240. When the maintenance personnel need to replace the part to be repaired, they only need to pull out the corresponding support frame 250.

[0074] After the inspection and replacement is completed, each support frame 250 is pushed back to the initial position, and the lower cover 200 is pressed to cover the cover 200 on the upper end of the barrel body 100 again, and then the adjustment plate 400 is rotated, and the driving groove 410 on the adjustment plate 400 drives each toggle part 320 to move synchronously in the direction away from the center of the cover 200, and the toggle part 320 drives the first locking rod 310 to move synchronously, and each first locking rod 310 is inserted into the corresponding lock hole 120 to achieve the purpose of locking the cover 200, and in this process, the avoidance groove 350 disengages from the second locking rod 330, and the inclined surface of the avoidance groove 350 presses against the upper end of the second locking rod 330, driving the second locking rod 330 to move downward, and the second locking rod 330 clamps the slider 240 to achieve the purpose of limiting.

[0075] In order to ensure that the first locking rod 310 can be inserted into the corresponding locking hole 120, an anti-fool structure can also be provided on the cover plate 200 and the barrel body 100, and the embodiment of the present application does not make any specific limitation on this.

[0076] The shell structure of the embodiment of the present application, when inspecting, only needs to rotate the adjustment plate 400 to open the locked cover plate 200, and release the limit of the slider 240 at the same time, and the cover plate 200 drives the support frame 250 and the parts to be inspected on the support frame 250 to be lifted off the barrel body 100 through the lifting mechanism 110, so that the maintenance personnel can inspect the parts to be inspected; the maintenance personnel can also pull out the support frame 250 to facilitate the replacement of the parts to be inspected in the support frame 250. The shell structure has the advantages of simple and fast inspection and / or replacement operations.

[0077] The embodiment of the present application further discloses a wind turbine assembly controller, which includes a control unit and the above-mentioned shell structure, and the control unit is connected to a support frame 250 of the shell structure.

[0078] In the wind turbine assembly controller in the embodiment of the present application, each control unit is installed on a corresponding support frame 250. When inspecting each control unit, it is only necessary to rotate the adjustment plate 400 to open the cover plate 200 in a locked state, and at the same time release the limit of the slider 240. The cover plate 200 drives the support frame 250 and each control unit to be lifted off the barrel body 100 through the lifting mechanism 110, so that the maintenance personnel can inspect each control unit; the maintenance personnel can also pull out the support frame 250 to facilitate the replacement of each control unit in the support frame 250 or the consumable parts on the control unit. The wind turbine assembly controller uses the above-mentioned shell structure, which has the advantages of simple and quick maintenance and / or replacement operations.
