Technical Field

[0001] The utility model relates to the field of surge protectors, in particular to a wind power surge protector. Background Art

[0002] In a wind power system, as a key electrical protection device, the performance and reliability of a surge protector are directly related to the operation safety of the entire wind farm. In the wiring process of existing wind power surge protectors, screw fixing methods are generally adopted. During the process of fixing the cable by squeezing it with a screw, since the tightening force of the screw is difficult to accurately control, the cable is often prone to deformation. In particular, the outer skin of the cable may be damaged due to excessive extrusion. This not only affects the electrical performance of the cable but also may cause safety hazards such as short circuits and electric leakage due to the damaged outer skin. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a wind power surge protector, and solve the following technical problems: how to avoid the deformation and damage of the cable during the fixing process, and how to achieve a long-term stable electrical connection.

[0004] To solve the problems existing in the prior art, the technical scheme adopted by the utility model is as follows:

[0011] Preferably, the top ends of the rotating cylinders extend upward to the outside of the device body, and an adjusting ring is fixedly connected to the outer sides of the top ends of the rotating cylinders.

[0012] Preferably, grooves are equidistantly opened on the outer side of the adjusting ring.

[0013] Preferably, sliding columns are provided on one side of the rotating cylinder. The sliding columns are slidably connected to the top of the device body.

[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] The wind power surge protector has a wiring cavity 1, a rotating cylinder 2, a fixing piece 3, a sliding rod 4, a pressing block 5 and a conductive copper sheet 6;

[0027] As Figures 1 to 5 shown, there are two wiring cavities 1, which are symmetrically opened at the top of the device body. Inside the wiring cavities 1, rotating cylinders 2 are rotatably connected. At the bottom of the rotating cylinders 2, inclined sliding holes are equidistantly opened. At the bottom of the wiring cavities 1, fixing pieces 3 are provided. On the surface of the fixing pieces 3, straight sliding holes are equidistantly opened. Inside the wiring cavities 1, sliding rods 4 are equidistantly provided. The top ends of the sliding rods 4 are slidably connected to the inclined sliding holes of the rotating cylinders 2, and the bottom ends of the sliding rods 4 are slidably connected to the straight sliding holes of the corresponding fixing pieces 3. On the outer sides of the sliding rods 4, pressing blocks 5 are fixedly connected. The pressing blocks 5 are distributed in an annular array inside the wiring cavities 1, and the pressing blocks 5 are in contact with each other. Below the wiring cavities 1, conductive copper sheets 6 are provided, and the conductive copper sheets 6 are arranged inside the device body.

[0028] During the wiring process, the cable of the wind power system first passes through the space inside the rotating cylinder 2, and the wire core is aligned with the conductive copper sheet 6 and ready to be inserted. At this time, the pressing blocks 5 are in the initial position, arranged in an annular array, and there are gaps at the centers of several pressing blocks 5 to allow the cable to pass through smoothly. Finally, its wire core is inserted into the conductive copper sheet 6 to achieve electrical connection. By rotating the adjusting ring 7, the rotating cylinder 2 rotates. Then, through the rotating inclined sliding holes, the sliding rods 4 are guided. While the top ends of the sliding rods 4 slide in the inclined sliding holes, the bottom ends of the sliding rods 4 slide along the straight sliding holes, guiding the sliding rods 4 and the pressing blocks 5 to approach each other. As the pressing blocks 5 approach each other, they will clamp the cable passing through them to ensure the stability and reliability of the electrical connection.

[0029] As Figures 1 to 5 shown, the top end of the rotating cylinder 2 extends upward to the outside of the device body. On the outer side of the top end of the rotating cylinder 2, an adjusting ring 7 is fixedly connected. By rotating the adjusting ring 7, the rotating cylinder 2 rotates, which is more convenient during adjustment.

[0030] As Figures 1 to 5 shown, on the outer side of the adjusting ring 7, grooves are equidistantly opened. The grooves can prevent slipping when rotating the adjusting ring 7.

[0031] As Figures 1 to 5 shown, on one side of the rotating cylinder 2, sliding columns 8 are provided. The sliding columns 8 are slidably connected to the top of the device body. At the top ends of the sliding columns 8, limiting blocks 9 are fixedly connected. On one side of the limiting blocks 9, convex ribs 10 are equidistantly provided. The convex ribs 10 cooperate with the grooves of the corresponding adjusting ring 7.

[0032] The limit block 9 is pulled to make the slide post 8 slide on the top of the device body. During this process, the convex rib 10 on one side of the limit block 9 will come out of the groove on the outside of the adjustment ring 7, releasing the lock on the rotating drum 2. After the convex rib 10 and the groove are offset, the rotating drum 2 can rotate freely, and the user can rotate and adjust it as needed.

[0033] like Figures 1 to 5 As shown, a spring 11 is provided at the bottom of the slide rod 4, and the slide rod 4 is elastically connected to the device body through the spring 11. After the adjustment is completed, the limit block 9 is loosened, and the elastic force of the spring 11 is used to push the slide rod 4 and the limit block 9 to reset. During the resetting process, the convex rib 10 will be re-engaged in the corresponding groove to position and lock the rotating drum 2 to ensure that it will not rotate accidentally during operation.

[0034] like Figures 1 to 5 As shown, the conductive copper sheet 6 is arranged in a wave shape, the middle part of the conductive copper sheet 6 is elastically bent downward to form a groove, and the two ends of the conductive copper sheet 6 are arched to form a clamping part. When the wire core is inserted into the conductive copper sheet 6, the conductive copper sheet 6 is elastically deformed by extrusion. When the wire core is inserted into the groove in the middle part of the conductive copper sheet 6, the clamping part of the conductive copper sheet 6 will fit with the wire core under the action of elasticity to form a stable electrical connection.

[0035] like Figures 1 to 5 As shown, retaining rings 12 are fixedly connected to the outer sides of both ends of the slide bar 4, and the retaining rings 12 allow the slide bar 4 to slide more smoothly.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
