[0021] Example Please see Figures 1-4 In this embodiment of the utility model, a circumferential welding fixture for offshore wind power suction anchors includes a cylindrical body 1, a supporting steel plate 2, and a protective component 5. The cylindrical body 1 is provided with a plurality of supporting steel plates 2, the upper end of the supporting steel plates 2 is provided with the protective component 5, and the upper end of the supporting steel plates 2 is provided with a plurality of hanging plates 3, which are in contact with the cylindrical body 1.

[0022] Specifically, two adjacent supporting steel plates 2 are spliced ​​together, and the mounting block 201 is inserted into the mounting groove 202. The limiting component 4 is set to limit and fix the mounting block 201. The operation is simple and facilitates the splicing of the supporting steel plates 2. Through the ring-shaped splicing structure of the supporting steel plates 2, personnel can walk and weld around the circumferential weld seam through the tooling, which can effectively save human and equipment resources and reduce site occupation. The protective component 5 is set to improve the safety of the operation. After the ring tooling is made, the tooling is hoisted to the top of the cylinder wall of the cylinder 1 by a gantry crane, and then slowly lowered. With the help of the hanging plate 3, the hanging plate 3 is hung on the cylinder wall of the cylinder 1.

[0023] The limiting component 4 includes a first groove 401, a first limiting block 402, and a first limiting groove 404. The mounting block 201 has a first groove 401 at both ends. The first limiting block 402 is slidably connected in the first groove 401. The first limiting block 402 is in the shape of a right trapezoid, and the inner wall of the mounting groove 202 is provided with a first limiting groove 404 corresponding to the first limiting block 402.

[0024] Specifically, through the cooperation of the first limiting block 402 and the first limiting groove 404, the first limiting block 402 thereby limits and fixes the mounting block 201.

[0025] A first spring 403 is provided in the first groove 401. One end of the first spring 403 is fixedly connected to the inner wall of the first groove 401, and the other end of the first spring 403 is fixedly connected to the first limiting block 402.

[0026] Specifically, the elastic potential energy of the first spring 403 facilitates the return of the first limiting block 402 to its original position.

[0028] Specifically, by placing a finger in the placement groove 407, the two pull blocks 405 are pulled closer to each other. The pull blocks 405 then drive the two first limiting blocks 402 to move closer to each other. The first limiting blocks 402 separate from the first limiting groove 404, thus facilitating the disassembly of the two adjacent support steel plates 2.

[0029] The protective component 5 includes a guardrail 501, a sliding rod 503, a sleeve 504, and a pivot seat 509. The upper end of the supporting steel plate 2 is provided with a plurality of pivot seats 509. The sleeve 504 is movably connected to the pivot seat 509.

The lower end of the guardrail 501 is provided with a magnet 502 that attracts the supporting steel plate 2.

[0030] Specifically, the combination of guardrail 501, magnet 502, slide bar 503 and sleeve 504 improves the safety of operation. When not in use, the guardrail 501 is attached to the supporting steel plate 2 by the rotating seat 509 and magnet 502, thereby reducing the space occupied by the protective component 5 and making it easy to store.

[0031] The upper end of the slide rod 503 is provided with a second groove 505, and a second limiting block 506 is slidably connected in the second groove 505. The second limiting block 506 is in the shape of a right trapezoid, and the sleeve 504 is provided with a plurality of second limiting grooves 508 corresponding to the second limiting block 506.

[0032] Specifically, by pulling the slide bar 503 upward, in conjunction with the second limiting block 506, the second spring 507, and the second limiting groove 508, the sliding slide bar 503 can be limited, thereby facilitating the adjustment of the height of the guardrail 501.

[0033] The upper end of the supporting steel plate 2 is provided with a first stop 510, the rear end of the first stop 510 is in contact with the sleeve 504, and the lower end of the sleeve 504 is in contact with a second stop 512.

The upper end of the third spring 513 is fixedly connected to the second stop 512, and the lower end of the third spring 513 is fixedly connected to the bottom end of the third groove 511.

[0034] Specifically, when the third spring 513 is in a compressed state, and the sleeve 504 is perpendicular to the support steel plate 2, the second stop 512 is raised under the action of the elastic force of the third spring 513, and the structure of the first stop 510 is designed to facilitate the vertical positioning of the sleeve 504.

[0035] The working principle of this utility model is as follows: In use, two adjacent supporting steel plates 2 are spliced ​​together, and the mounting block 201 is inserted into the mounting groove 202. When the mounting block 201 is inserted into the mounting groove 202, it drives the two first limiting blocks 402 to move closer to each other. The first limiting block 402 compresses the first spring 403. When the first limiting block 402 moves to the position of the first limiting groove 404, the elastic potential energy of the first spring 403 facilitates the return of the first limiting block 402 to its original position. The first limiting block 402 is then inserted into the first limiting groove 404, thereby limiting and fixing the mounting block 201. The operation is simple and facilitates the splicing of the supporting steel plates 2. Through the ring-shaped splicing structure of the supporting steel plates 2, personnel can walk around the circumferential weld for welding using tooling, which can effectively save human and equipment resources and reduce site occupation. The moving guardrail 501 moves upward, which in turn drives the sliding rod 503 and sleeve 504 to rotate, making them vertically support the steel plate 2. At this time, the second stop block 512 rises under the action of the third spring 513. The structure of the first stop block 510 facilitates the vertical positioning of the sleeve 504, pulling the sliding rod 503 to slide upward. The cooperation of the structure of the second limit block 506, the second spring 507 and the second limit groove 508 facilitates the limitation of the sliding rod 503, thereby facilitating the adjustment of the height of the guardrail 501. The protective component 5 facilitates the improvement of the safety of the operation. After the ring tooling is made, the tooling is hoisted to the top of the cylinder wall of the cylinder 1 by a gantry crane, and then slowly lowered. With the cooperation of the hanging plate 3, the hanging plate 3 is hung on the cylinder wall of the cylinder 1.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
