Description

Technical Field

[0001] The utility model relates to the field of fan protection equipment, in particular to a protection structure for a fan foundation. Background Technique

[0002] Offshore wind power is a field with a relatively high degree of technical complexity. The monopile foundation has become the most widely used foundation form in the field of offshore wind power projects. After the sea current encounters the obstruction of the pile column, it will flow around, causing the sea current to accelerate the flow velocity around the pile column, thus easily forming a scouring pit on the outer periphery of the monopile foundation. Therefore, it is necessary to buffer and protect the contact position between the monopile and the wind power.

[0003] According to a patent document with the publication number of CN111576470A, which discloses a monopile scouring protection structure for a marine engineering fan foundation and its scouring depth reduction calculation method, it includes an outer fan ring permeable structure, a middle ring permeable layer, and an inner ring energy dissipation layer that are at a certain distance from each other. The outer fan ring permeable structure, the middle ring permeable layer, and the inner ring energy dissipation layer are fixedly connected by a steel truss. Multiple permeable circular holes are provided on the outer fan ring permeable structure, the middle ring permeable layer, and the inner ring energy dissipation layer. When this technical solution is used, the characteristics of low height-width ratio and high permeability are used to protect the seabed around the monopile foundation from scouring, and the scouring of the sea current around the monopile foundation is greatly reduced through the above two characteristics. For the above technical solution, although the scouring prevention is achieved, the sealing protection of the connection point between the monopile and the fan cannot be carried out during use, which is inconvenient during use. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a protection structure for a fan foundation to solve the problems raised in the above background technology. The structure of the utility model is novel. During use, the fixing seat and the support seat shield and protect the mounting seat through the cavity, avoiding damage caused by direct impact of sea waves on the mounting seat. In addition, the fixing plate further shields and protects the position of the fixing bolt from the side of the connecting seat.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions: A protection structure for a fan foundation includes a fixing seat. A support seat is movably installed on the side of the fixing seat. Connecting seats are welded on the sides of the support seat and the fixing seat respectively. The connecting seats are connected by fixing bolts. Cavities are opened inside the fixing seat and the support seat. Sealing rings are fixed on the inner walls of the cavities. A fixing plate is movably installed on one side between the fixing seat and the support seat. Support plates are respectively installed on the sides of the fixing seat and the support seat. Arc-shaped plates are welded on the tops of the support plates and the fixing plate.

[0006] Further, a slotted groove is formed on the side of the fixed seat, a fixing groove is formed on the side of the support seat, and a fixing block is movably installed inside the fixing groove.

[0007] Further, an installation block is movably installed inside the slotted groove, and both the installation block and the fixing block are welded to the inner wall of the fixing plate.

[0008] Further, limiting grooves are formed on the other sides of both the fixed seat and the support seat, a support mechanism is fixedly installed inside the limiting grooves, a limiting block is movably installed inside the limiting grooves, and the limiting block is fixed to the inner wall of the support plate.

[0009] Further, a fixing column and a fan base are movably installed inside the cavity, a mounting seat is fixed between the fan base and the fixing column, and fastening bolts are fixedly installed between the mounting seats.

[0010] Further, convex blocks are welded to one sides of both the support plate and the fixing plate, and the convex blocks are matched with each other in an up-and-down offset manner.

[0011] The beneficial effects of the utility model:

[0012] 1. For the protection structure of a wind turbine foundation, when in use, the fixed seat and the support seat shield and protect between the mounting seats through the cavity, avoiding damage caused by direct impact of sea waves on the mounting seats.

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a protection structure for a fan foundation, including a fixed seat 1, a support seat 2 is movably installed on the side of the fixed seat 1, connecting seats 3 are welded on the sides of the support seat 2 and the fixed seat 1, the connecting seats 3 are connected by fixing bolts 14, cavities 4 are opened inside the fixed seat 1 and the support seat 2, a sealing ring 5 is fixed on the inner wall of the cavity 4, a fixing plate 6 is movably installed on one side between the fixed seat 1 and the support seat 2, support plates 7 are respectively installed on the sides of the fixed seat 1 and the support seat 2, arc plates 9 are welded on the tops of the support plates 7 and the fixing plate 6, a slot 10 is opened on the side of the fixed seat 1, a fixing groove 11 is opened on the side of the support seat 2, a fixing block 19 is movably installed inside the fixing groove 11, and the arc plate 9 filters the impact force transmitted by the sea waves and discharges it upward, thereby avoiding the damage caused by the vertical impact of the sponge on the fixed seat 1 and the support seat 2.

[0022] In this embodiment, a mounting block 20 is movably installed inside the slot 10, both the mounting block 20 and the fixing block 19 are welded on the inner wall of the fixing plate 6, limiting grooves 12 are opened on the other sides of the fixed seat 1 and the support seat 2, a support mechanism 13 is fixedly installed inside the limiting groove 12, a limiting block is movably installed inside the limiting groove 12, the limiting block is fixed on the inner wall of the support plate 7, a fixing column 16 and a fan seat 15 are movably installed inside the cavity 4, a mounting seat 17 is fixed between the fan seat 15 and the fixing column 16, fastening bolts 18 are fixedly installed between the mounting seats 17, convex blocks 8 are welded on one side of the support plate 7 and the fixing plate 6, and the convex blocks 8 are matched with each other in a vertically offset manner. The support mechanism 13 is a support spring, and the support spring generates a downward thrust to return after the fixing plate 6 and the support plate 7 move upward.

[0023] When the device is in use, the fixed seat 1 and the support seat 2 are installed on the fan seat 15 and the fixed column 16 in an up-and-down staggered manner. After the installation of the fixed seat 1 and the support seat 2 is completed, the fixed seat 1 is lowered and the support seat 2 is raised. The mounting block 20 on the fixing plate 6 is slidably installed inside the slot 10. The cooperation between the mounting block 20 and the slot 10 realizes the preliminary limit fixation of the fixed seat 1 and the support seat 2. After the fixed seat 1 and the support seat 2 are aligned, the fixing plate 6 is moved upward. After the fixing plate 6 is moved upward, the position of the fixing bolt 14 is exposed. The fixing bolt 14 is installed between the connecting seats 3 to limit and fix the fixed seat 1 and the support seat 2. After the installation of the fixing bolt 14 is completed, the thrust generated by the support mechanism 13 causes the fixing plate 6 to descend. When the fixing plate 6 descends, the bottom of the fixing groove 11 limits the fixing block 19. During use, the cavity 4 inside the fixed seat 1 and the support seat 2 shields the position of the mounting seat 17. The sealing rings 5 cooperate with the fan seat 15 and the fixed column 16 respectively for sealing. When the sea wave impacts the fixing plate 6 or the support plate 7, under the impact of the sea wave, the support plate 7 or the fixing plate 6 moves upward. While the support plate 7 or the fixing plate 6 moves upward, the sea wave is led outwards through the arc-shaped plate 9. After the sea wave is led out, the fixing plate 6 or the support plate 7 loses the thrust. Under the thrust of the support mechanism 13, the fixing plate 6 and the support plate 7 return downward for the next anti-erosion protection. In addition, when it is necessary to climb to the top of the fan seat 15, the staff can climb through the steps formed by the cooperation between the convex blocks 8.
