[0002] The jacket is an open structure made of a series of tubular components welded together. It resists external forces by piles driven into the seabed and is one of the commonly used foundation forms for offshore wind power platforms.
[0003] The above-mentioned device does not have a structure for preventing collision of the reinforcement rods inside the jacket when in use, so that a large number of reinforcement rods are arranged inside the jacket when the existing offshore wind turbine jacket foundation is in use. Due to the complex sea environment and the large number of ships, and the thinner reinforcement rods inside the jacket than the main frame, if the reinforcement rods inside the jacket collide seriously with moving objects or ships on the sea, the reinforcement rods are easily damaged and bent, resulting in a significant reduction in the stability of the jacket. Based on the deficiencies of the existing technology, the utility model designs an anti-collision structure for the offshore wind turbine foundation. Utility Model Content

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The anti-collision structure of the offshore wind turbine foundation is such that when a moving object is about to collide with a reinforcement frame, the anti-collision plate will first contact the moving object and move inward, and the moving anti-collision plate will push the first hinge joint and the second hinge joint to move backward through the connecting block and the rotating shaft. Since the second hinge joint and the first hinge joint are respectively connected to the first damping rod and the second damping rod, when the first hinge joint and the second hinge joint move backward, the first damping rod and the second damping rod can generate resistance to consume the thrust applied by the moving object on the anti-collision plate, thereby slowing down the moving speed of the moving object and the anti-collision plate and reducing the impact force. If the water surface height changes, the floating airbag can push the anti-collision plate to rise and fall accordingly under the limit of the first lifting rod, the first connecting frame, the second lifting rod and the second connecting frame, so that the anti-collision plate is always above the water surface for protective operations. The device is convenient for protecting the reinforcement frame. BRIEF DESCRIPTION OF THE DRAWINGS

The four sets of anti-collision mechanisms 3 are arranged between the four jacket bodies 1, and the second hinge joint 308 and the rotating hole 309 are rotatably hinged on the rotating shaft 310.
[0026] By providing a first lifting rod 301, a first connecting frame 302, a second lifting rod 303, a second connecting frame 304, an anti-collision plate 312 and a floating airbag 313, the anti-collision plate 312 can be fixedly connected to the jacket frame body 1 and can move accordingly as the sea water level rises, so that the anti-collision plate 312 can always be above the water surface to protect the reinforcement frame 101. By providing a first damping rod 305, a second damping rod 306, a first hinge joint 307, a second hinge joint 308 and a rotating hole 309, the impact force of a moving object colliding with the anti-collision plate 312 can be absorbed and the moving object can be decelerated, thereby preventing the moving object from colliding with the reinforcement frame 101 or causing the reinforcement frame 101 to collide with the reinforcement frame 101 at a relatively high speed.
[0027] Working principle: When an anti-collision structure of an offshore wind turbine foundation is used, in the initial state, first, four groups of reinforcement frames 101 are fixedly connected between four groups of jacket frames 1, and a ladder 104 is connected to one side of the jacket frame body 1 through a connecting rod 103, and the top of the jacket frame body 1 is respectively connected to a connecting seat 201, a connecting seat 201 and a sub-platform 203, so that workers can board the basic platform to work, and the first lifting rod 301, the first connecting frame 302, the second lifting rod 303 and the second connecting frame 304 connected on the two groups of jacket frame bodies 1 on the same side are respectively connected by a first damping rod 305, a second damping rod 306, a first hinge 307 and a second hinge 308, and the first hinge 307 and the second hinge 308 are connected to the anti-collision plate 312 through a rotating shaft 310, so as to prevent external objects or ships from colliding with the reinforcement frames 101 installed between the two groups of jacket frame bodies 1 on the same side;
[0028] When the reinforcement frame 101 needs to be protected, first, when a moving object is about to collide with the reinforcement frame 101, the anti-collision plate 312 will first contact the moving object and move inward, and the moving anti-collision plate 312 will push the first hinge joint 307 and the second hinge joint 308 to move backward through the connecting block 311 and the rotating shaft 310. Since the second hinge joint 308 and the first hinge joint 307 are connected to the first damping rod 305 and the second damping rod 306 respectively, when the first hinge joint 307 and the second hinge joint 308 move backward, the second hinge joint 307 and the second hinge joint 308 will move backward. A damping rod 305 and a second damping rod 306 can generate resistance to consume the thrust exerted by the moving object on the anti-collision plate 312, thereby slowing down the moving object and the anti-collision plate 312 and reducing the impact force. If the water surface height changes, the floating airbag 313 can push the anti-collision plate 312 to rise and fall accordingly under the limit of the first lifting rod 301, the first connecting frame 302, the second lifting rod 303 and the second connecting frame 304, so that the anti-collision plate 312 is always above the water surface for protective operations. This device is convenient for protecting the reinforcement frame 101.
