Description

Technical Field

[0001] This utility model relates to the field of cable installation technology in offshore wind tunnels, specifically to a medium-voltage cable installation and connection structure. Background Technology

[0002] Offshore wind turbines are the core power generation devices used in offshore wind power. They mainly consist of wind turbine generators, towers, support structures, and foundations. They convert wind energy into electrical energy by using blade aerodynamics to generate lift and drive the generator. They must adapt to the marine environment and have higher requirements for corrosion resistance and typhoon resistance. The electricity is stepped up by a transformer substation and transmitted via submarine cables. This unit is based on a modified design of onshore wind turbines, with specific improvements made to the foundation structure, dehumidification system, and installation and maintenance for the marine environment.

[0003] Medium-voltage cables inside the tower need to be secured using clamps on cable supports. Typically, the cable is first placed on the mounting bracket for support, and then the clamps are used to hold and secure it. However, securing the cable requires moving one end to a designated position before the clamps on the bracket can hold and secure it. Since the cable is not secured or limited during movement, it can become tangled as it moves on the bracket. Therefore, a medium-voltage cable installation and connection structure is needed.

[0004] This utility model proposes a medium-voltage cable installation and connection structure to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where cables easily deviate from their designated routes and become tangled during movement, and to propose a medium-voltage cable installation and connection structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a medium-voltage cable installation and connection structure, including an installation block installed on a cylinder wall, a connector connected to one end side wall of the installation block, a fixing member installed on the connector, and a support member installed on the fixing member;

[0007] The support component includes a lower cover plate, a first side block, a lower placement groove, an upper cover plate, an upper placement groove, a second side block, a limiting bolt, an adjusting screw, and a pressure plate. The lower cover plate has a lower placement groove at its top end, and the upper cover plate is rotatably connected to the top end of the lower cover plate. The upper cover plate has an upper placement groove at its bottom end. Two symmetrically distributed first side blocks are connected to one side wall of the lower cover plate, and two symmetrically distributed second side blocks are connected to one side wall of the upper cover plate. Connecting screw holes are provided at the top ends of the first and second side blocks, and the limiting bolts are internally threaded into the connecting screw holes. An adjusting screw hole is provided at the center of the top end of the upper cover plate, and an adjusting screw is internally threaded into the adjusting screw hole. The pressure plate is connected to the bottom end of the adjusting screw.

[0008] As a preferred embodiment of this utility model, the mounting block is threaded with a mounting bolt, which can be threadedly connected to the cylinder wall.

[0009] As a preferred embodiment of this utility model, the first side block can be attached to the second side block, and the connecting screw hole on the first side block can be aligned with the connecting screw hole on the second side block.

[0010] As a preferred embodiment of this utility model, both the lower placement groove and the upper placement groove are semi-cylindrical in shape.

[0011] As a preferred technical solution of this utility model, the connector includes a bracket and a slot. One end of the bracket is connected to the mounting block. The top end of the bracket has a plurality of slots arranged in an array. The top end of the bracket has a plurality of top screw holes, with each pair of top screw holes located on both sides of the slot.

[0012] As a preferred technical solution of this utility model, the fixing component includes an insert block, a connecting block, and a fixing bolt. The inner sidewall of the slot is connected to the insert block, and the sidewall of the insert block is connected to two symmetrically distributed connecting blocks. The top of the connecting block is provided with a bottom screw hole, and a fixing bolt is connected in the bottom screw hole. The bottom screw hole can be aligned with the top screw hole, and the fixing bolt can be threadedly connected to the top screw hole. The bottom end of the lower cover plate is connected to the top end of the insert block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention involves unscrewing the limiting bolt from the connecting screw hole, rotating the upper cover plate to open it, and opening the lower placement slot. The cable body is then placed into the lower placement slot. The upper and lower cover plates are then closed, allowing the first and second side blocks to fit together. The limiting bolt is then screwed into the connecting screw hole, fixing the first and second side blocks as a single unit. This creates a circular channel between the upper and lower placement slots, allowing the cable body to move along the circular channel without detaching from its intended installation position and preventing it from tangling with adjacent cables. After the cable body has moved, the adjusting screw is rotated to press the pressure plate against the cable body, thus securing it in place. Attached Figure Description
