[0020] In order to make the purpose, technical solution and advantages of the present invention clearer and more understandable, the technical solution of the present invention will be further described in detail below in conjunction with the drawings in the embodiments of the present invention.

[0021] Reference Figures 1 to 5 , the utility model described in an offshore wind turbine tower channel sealing device includes two groups of sealing components, the sealing components including a sealing plate 401, two clamping strips 402 and two connecting plates 406, the two sealing plates 401 are respectively rotatably installed at the two ends of the channel 2 and a waiting chamber 3 is formed between the two sealing plates 401, both sides of the channel 2 end are provided with a clamping groove 5 adapted to the clamping strip 402, both sides of the sealing plate 401 are provided with a movable groove 407 adapted to the clamping strip 402, the two clamping strips 402 are respectively slidably installed in the movable groove 407, the clamping strip 402 and the inner end surface of the movable groove 407 are connected by an elastic connecting piece, and the clamping strip 402 can be slidably inserted into the nearest clamping groove 5, the two connecting plates 406 are respectively fixedly connected to the two clamping strips 402 and are both slidably connected to the sealing plate 401.

[0022] The blocking plate 401 is provided with a sliding groove 405 , and the connecting plate 406 is slidably inserted into the sliding groove 405 .

[0023] The elastic connecting member includes a first spring 403 and a telescopic rod 404 . Both ends of the telescopic rod 404 are fixedly connected to the inner end surface of the movable groove 407 and the clamping strip 402 respectively. The first spring 403 is sleeved on the telescopic rod 404 .

[0024] When the blocking plate 401 seals the port of channel 2, the card strip 402 is pushed by the first spring 403 and inserted into the card slot 5 of channel 2. When the staff enters the tower body 1 through channel 2 to perform inspection and maintenance, they first pull the two sets of connecting plates 406 to slide in the sliding groove 405, and then drive the card strip 402 to slide in the moving groove 407 through the connecting plates 406. At this time, the first spring 403 is compressed and the telescopic rod 404 also retracts, so that the card strip 402 gradually moves out of the card slot 5 and retracts into the moving groove 407. During this process, the telescopic rod 404 can support the card strip 402, thereby improving the stability of the movement of the card strip 402.

[0025] When the locking plate 401 is needed to be closed again, the staff member comes out of the waiting room 3 and rotates the blocking plate 401 until the locking bar 402 corresponds to the locking groove 5 of the channel 2. Then, the connecting plate 406 is released. At this time, the first spring 403 rebounds and drives the locking bar 402 to be inserted into the locking groove 5 of the channel 2 to lock the blocking plate 401. During the whole process, the outermost blocking plate 401 of the channel 2 can play a sealing and protective effect, which can prevent a large amount of humid air from entering the interior of the tower body 1. In addition, the blocking plate 401 is opened by the locking method, which is usually easier to operate and lock and disassemble than bolt fixing and disassembly, saving time and effort, improving the use effect of this structure, and meeting actual use needs.

[0026] In other examples, positioning plates 412 are fixedly installed at both ends of channel 2 to interfere with the blocking plate 401. During the process of flipping and resetting the blocking plate 401, until the blocking plate 401 contacts the positioning plates 412, the locking strip 402 corresponds to the locking groove of channel 2. The positioning plates 412 can be used to position the blocking plate 401 when flipped, improving the quick engagement and fixing effect.

[0027] A guide rod 408 and a guide sleeve 409 are fixedly mounted on opposite sides of the two connecting plates 406. The guide rod 408 is slidably inserted into the guide sleeve 409. A second spring 411 is connected between the guide rod 408 and the guide sleeve 409. Anti-slip sleeves 410 are provided on the outer surfaces of the guide rod 408 and the guide sleeve 409.

[0028] In this way, when the staff enters the tower body 1 through the channel 2 for inspection and maintenance, they can hold the anti-slip sleeve 410 and pull it apart on both sides to make the guide rod 408 slide in the guide sleeve 409 and make them approach each other. While the guide rod 408 slides in the guide sleeve 409, the second spring 411 is compressed. By setting the second spring 411, its rebound force can be increased, which is convenient for resetting the card strip 402 that is pulled later. In this process, by setting the anti-slip sleeve 410, the friction between the hand and the guide rod 408 and the guide sleeve 409 can be increased, which can better promote the relative movement of the guide rod 408 and the guide sleeve 409. As the guide rod 408 and the guide sleeve 409 move, the two sets of connecting plates 406 are driven to slide in the sliding groove 405, and finally the sealing plate 401 is rotated to achieve opening and closing.
