Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a cable harness device for wind power generation. Background Art

[0002] Wind power generation equipment refers to electromechanical equipment that converts wind kinetic energy into electrical energy. Due to its high environmental protection and large wind energy reserves, wind power generation equipment is more common in vast plains and is also developing rapidly. Since wind power generation equipment requires the use of generators and various electromechanical equipment, cables are indispensable. In order to protect the cables, cable harnesses are needed to restrain and protect the cables.

[0003] Most of the existing cable bundling devices are multi-hole plates, which use separate through-holes to insert different cables, making the cables more regular and non-contacting. This device can reduce the friction between cables and has certain practicality, but there is still room for improvement. For example: when this device passes the cable through the through-hole, the cable surface contacts the inner ring of the through-hole. Once the cable needs to turn after passing through the through-hole, the cable surface will rub against the sharp edges of the inner ring of the through-hole, and due to the influence of the rotation of the blades in the wind turbine tower, there will be vibrations with small amplitudes, which will cause the cable to constantly rub against the sharp edges. The sharp edges are like a sharp knife, constantly cutting the cable surface, resulting in poor protection of the cable surface. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a cable harness device for wind power generation.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The connecting assembly includes a first connecting frame and a second connecting frame. A rectangular slot is provided on the front surface of the first connecting frame and the lower surface of the second connecting frame. Two positioning bolts are threadedly connected to the upper surface of the first connecting frame and the front surface of the second connecting frame. Strip plug plates are fixedly connected to the left and right sides of the parallel frame.

[0008] Preferably, the two wire harness through holes of the corner frame and the parallel frame have the same inner diameter and are positioned corresponding to each other, and the cables can pass through the wire harness through holes of the parallel frame and through the corner frame.

[0009] Preferably, the bottom end of the pull rod is fixedly connected to the upper surface of the movable plate, and the pull rod can drive the movable plate to rise and fall.

[0010] Preferably, the top end of the spring overlaps the inner top wall of the positioning frame, and the bottom end overlaps the upper surface of the movable plate. When the movable plate is driven to rise by the pull rod, the movable plate can squeeze the spring to cause it to deform.

[0011] Preferably, the upper surface of the parallel frame is provided with two circular holes adapted to the connecting rods, and the connecting rods can drive the arc-shaped extrusion pads to move up and down through the circular holes.

[0012] Preferably, the strip plug plate is adapted to the rectangular slot, and two limiting screw holes adapted to the positioning bolts are provided on the upper surface of the strip plug plate. The strip plug plate can be inserted into the rectangular slot and fixed with the positioning bolts, thereby completing the assembly and splicing of the corner rack and the parallel rack.

[0013] The beneficial effects of the utility model are:

[0014] 1. By arranging a pull rod, a spring, a movable plate, a connecting rod and an arc-shaped extrusion pad, the force generated by the spring can drive the arc-shaped extrusion pad to press the cable tightly into the cable bundle through-hole, thereby fixing the cable and ensuring that the cable will not be twisted due to external pressure. At the same time, the corners of the cable are in contact with the first rubber protective pad and the second rubber protective pad. The elasticity and softness of the two rubber pads can reduce friction with the cable surface, thereby improving the protection effect of the cable surface;

[0022] The upper surface of the parallel frame 2 is fixedly connected to two harness assemblies, and the harness assembly includes a positioning frame 6, a circular hole is opened on the upper surface of the positioning frame 6, and a pull rod 7 is slidably connected to the inner wall of the circular hole, and a spring 8 is sleeved on the surface of the pull rod 7, and a movable plate 9 is slidably connected to the inner wall of the positioning frame 6. The bottom end of the pull rod 7 is fixedly connected to the upper surface of the movable plate 9, and the top of the spring 8 overlaps the inner top wall of the positioning frame 6, and the bottom end overlaps the upper surface of the movable plate 9, and the lower surface of the movable plate 9 is fixedly connected to a connecting rod 10, and the bottom end of the connecting rod 10 is fixedly connected to an arc-shaped extrusion pad 11. The upper surface of the parallel frame 2 is provided with two circular holes adapted to the connecting rod 10;

[0023] After the cable passes through the harness hole, the force generated by the spring 8 can squeeze the movable plate 9 in a fixed position. The movable plate 9 drives the arc-shaped squeezing pad 11 downward to squeeze the cable surface through the connecting rod 10, thereby fixing the cable and ensuring that the cable will not be twisted due to external pressure.

[0024] An arc-shaped fixing block 12 is fixedly connected to the inner top wall of the corner frame 1, and a first rubber protective pad 13 is fixedly connected to the arc surface of the arc-shaped fixing block 12. A second rubber protective pad 14 is fixedly connected to the inner wall of the arc surface of the corner frame 1. The cable corner can contact the first rubber protective pad 13 and the second rubber protective pad 14. The elasticity of the two rubber protective pads themselves can reduce the friction between the cable surface and the cable surface, thereby improving the protection effect of the cable surface.

[0026] The two strip-shaped plug plates 18 on the left and right sides of the parallel rack 2 can be inserted into the two first connecting frames 15, so that the corner rack 1 and the parallel rack 2 can be assembled and spliced, and the parallel rack 2 can also be disassembled and used alone, and the cables can be bundled in multiple sections, which is more flexible.

[0027] Working principle: Pull the two pull rods 7 upwards to make the movable plate 9 drive the spring 8 to squeeze and deform, and at the same time drive the arc-shaped extrusion pad 11 to rise through the connecting rod 10. At this time, pass the cable through the two bundle holes, and the cable comes out from the bottom of the corner frame 1. Loosen the two pull rods 7. The spring 8 can drive the movable plate 9 down through the reaction force, thereby driving the arc-shaped extrusion pad 11 to squeeze the cable surface through the connecting rod 10, so as to position the cable. Use the mounting frame 4 and the mounting bolts 5 to fix the device to the inner wall of the tower. At the same time, the cable corner is fixed by the first rubber The protective pad 13 and the second rubber protective pad 14 are in contact and pressed tightly. The elasticity of the two rubber protective pads themselves can ensure that there will be no large friction between the cables, and the surface protection of the cable corners is better.
