Technical Field

[0001] The utility model relates to the technical field of jacket frame platforms, in particular to a jacket frame platform for an offshore wind turbine. Background Art

[0002] An offshore wind turbine jacket platform is a structural platform used to support offshore wind turbines. It consists of a spatial frame structure composed of multiple steel pipes, anchored to the seabed by piling. These pipes possess high strength and stability, capable of withstanding the complex offshore loads, including wind, wave, and current forces.

[0003] The above device does not have a structure for preventing the jacket platform from falling when in use, so that when personnel on the existing offshore wind turbine jacket platform go up to work, they mostly need to use the ladder on the side of the jacket platform to go up to work. However, since the safety belt buckle and the ladder need to be manually disassembled and assembled multiple times during the climbing process, it is not only cumbersome, but also prone to falling incidents during the unlocking and changing of the fixed points. Based on the deficiencies of the existing technology, the utility model designs a jacket platform for offshore wind turbines. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a jacket platform for an offshore wind turbine, which has the advantage of preventing a jacket platform from falling by climbing a ladder.

[0005] The utility model provides the following technical solution: a jacket platform for an offshore wind turbine, comprising a jacket body, a jacket platform provided on the top of the jacket body, and a side surface of the jacket body provided with an anti-fall mechanism for preventing workers from falling when climbing a ladder;

[0006] The anti-fall mechanism includes an anti-fall side plate, a connecting column, a hinge block, an anti-fall plate, a spring, an anti-fall block and a connecting buckle. The anti-fall side plate is fixedly connected to one side of the catheter frame body, the connecting column is fixedly connected to one side of the anti-fall side plate, the hinge block is fixedly connected to the inner side of the anti-fall side plate, the anti-fall plate is rotatably hinged on the hinge block, one end of the spring is fixedly connected to the upper surface of the anti-fall plate, the anti-fall block is fixedly connected to the side wall of the connecting column, and the connecting buckle is slidably clamped on the connecting column.

[0007] As an optimal technical solution of the present invention, a reinforcement frame is fixedly connected to the inner side of the catheter frame body, a bottom column is fixedly connected to the bottom of the catheter frame body, a ladder is fixedly connected to the outer side of the catheter frame body, and a connecting rod is fixedly connected to the side of the ladder facing the catheter frame body.

[0008] As a preferred technical solution of the present invention, the lower surface of the jacket platform is fixedly connected to a connecting seat, one side of the connecting seat is fixedly connected to a secondary platform, and the upper surface of the jacket platform is fixedly connected to a fence.

[0009] As a preferred technical solution of the present invention, the connecting rod is fixedly connected between the ladder and the jacket body.

[0010] As a preferred technical solution of the present invention, the four corners of the bottom of the connecting seat are respectively fixedly connected to the top ends of the four catheter rack bodies.

[0011] As a preferred technical solution of the present invention, the auxiliary platform is arranged on one side of the top end of the ladder.

[0012] As a preferred technical solution of the present invention, the spring is arranged between the side wall of the anti-fall side plate and the upper surface of the anti-fall plate.

[0013] As a preferred technical solution of the present invention, the anti-fall plate is movably connected above the anti-fall block, and the lower surface of the anti-fall plate is in contact with the upper surface of the anti-fall block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the worker climbs up the ladder, the safety belt will pull the connecting buckle upwards, and when the worker and the connecting buckle move up to a certain distance, the upward-moving connecting buckle will contact the anti-fall plate and push the anti-fall plate to rotate upwards and expand under the limit of the hinge block, so that the connecting buckle is transferred from below the anti-fall plate and the anti-fall block to above the anti-fall plate and the anti-fall block, so that the worker can achieve staged fall prevention without unlocking it by himself, and when the connecting buckle moves to above the anti-fall plate, the compressed spring will rebound and push the anti-fall plate to rotate in the opposite direction until the anti-fall plate is re-connected to the anti-fall block, so as to prevent the anti-fall function from failing to limit the connecting buckle when the worker falls.

[0025] By setting the anti-fall side plate 301, the connecting column 302 and the connecting buckle 307, the connecting buckle 307 can be connected to the catheter frame body 1 through the anti-fall side plate 301 and the connecting column 302 to prevent falling. By setting the anti-fall plate 304 and the anti-fall block 306, and multiple groups of anti-fall plates 304 and anti-fall blocks 306 are provided on the anti-fall side plate 301 and the connecting column 302, the workers can achieve short-distance fall prevention even at different heights during the ladder climbing process. By setting the hinge block 303 and the spring 305, the anti-fall plate 304 can be flipped up and reset downward, so that the connecting buckle 307 can push the anti-fall plate 304 to move up into the next area during the upward movement. If a fall occurs, the anti-fall plate 304 below the current area can quickly prevent the connecting buckle 307 from continuing to fall.

[0026] Working principle: When a jacket platform of an offshore wind turbine is used, in the initial state, the reinforcement frame 101 and the bottom column 102 are fixedly connected to the inner side and the bottom of the four jacket bodies 1 respectively. A secondary platform 202 is set on one side of the connection seat 201 installed on the top of the jacket body 1, and the top of the ladder 103 installed on the side wall of the jacket body 1 through the connecting rod 104 is set on one side of the secondary platform 202, so that the staff can stay on the secondary platform 202 for a while. A jacket platform 2 is set on the top of the connection seat 201, and the fence 203 is set on the other side of the jacket body 1. It is arranged at the edge of the jacket platform 2 to facilitate the installation of offshore wind turbines and provide safe operation for workers. The anti-fall side plate 301 fixedly connected to the jacket body 1 is arranged on one side of the ladder 103. The connecting column 302 fixedly connected to the outside of the anti-fall side plate 301 is also fixedly connected to the anti-fall block 306. The anti-fall plate 304 connected to the anti-fall block 306 on one side of the anti-fall side plate 301 through the hinge block 303 overlaps with the anti-fall block 306. At the same time, the connecting buckle 307 is connected to the connecting column 302, so that workers do not need to frequently adjust the safety lock when climbing the ladder.

[0027] When the worker needs to quickly climb onto the jacket platform 2 to perform operations, the worker first connects his or her own safety belt to the connecting buckle 307 and checks the safety. Then, the connecting buckle 307 is buckled to the bottom end of the connecting column 302 and locked. At this time, the worker can climb onto the ladder 103 and climb up. During the climbing process, the safety belt will pull the connecting buckle 307 upward. After the worker and the connecting buckle 307 move up to a certain distance, the upward-moving connecting buckle 307 will contact the anti-fall plate 304 and push the anti-fall plate 304 to rotate upward under the limit of the hinge block 303, so that the connecting buckle 307 can be rotated and expanded. 07 is transferred from the bottom of the fall-stop plate 304 and the fall-stop block 306 to the top of the fall-stop plate 304 and the fall-stop block 306, so that the staff can achieve staged fall prevention without unlocking it by themselves. When the connecting buckle 307 moves to the top of the fall-stop plate 304, the compressed spring 305 will rebound and push the fall-stop plate 304 to rotate in the opposite direction until the fall-stop plate 304 is re-connected to the fall-stop block 306, preventing the fall-stop plate 304 and the fall-stop block 306 from being unable to limit the connecting buckle 307 when a person falls, resulting in the failure of the fall-prevention function. This device is convenient for staged fall prevention for staff.
