Description

Technical Field

[0001] This utility model relates to the field of high-voltage cable technology, and in particular to a high-voltage cable support fixing device. Background Technology

[0002] High-voltage cables are a type of power cable, mainly used for large-scale and medium-to-long-distance power transmission.

[0003] During transmission, high-voltage cables are typically attached to high-voltage power towers and secured with clamps. However, this installation method has certain drawbacks. The direct clamping of high-voltage cables onto the towers results in insufficient buffering when subjected to external forces. For example, birds frequently perch on the cables in groups, causing strain on the clamped connection points at both ends of the cable. Over time, this leads to wear and tear at the connection points, which is a major reason why most high-voltage cable breaks occur at these points. This reduces the lifespan of high-voltage cables and poses certain safety risks.

[0004] Therefore, it is necessary to provide a new high-voltage cable support fixing device to solve the above-mentioned technical problems. Utility Model Content

[0023] Figure 5 is Figure 1 a schematic side view structure diagram of the rotating disk shown. The high-voltage cable bracket fixing device includes: a support plate 1 and two vertical plates 3 fixedly installed on the top of the support plate 1. The two vertical plates 3 are symmetrically arranged based on the middle of the support plate 1. A rotating rod 4 is rotatably installed on the two vertical plates 3. The rotating rod 4 is rotatably connected to the two vertical plates 3 through a rotating bearing, and both ends of the rotating rod 4 penetrate through the two vertical plates 3 respectively. A wire winding wheel 5 is fixedly sleeved on the outer wall of the rotating rod 4. A cable 6 is wound on the wire winding wheel 5. The wire winding wheel 5 is located in the middle of the rotating rod 4. Both ends of the cable 6 extend outside the support plate 1. A wire retracting mechanism is arranged on the outer wall of one side of the two vertical plates 3.

[0024] On the outer wall of one side of the two vertical plates 3, a front plate 7 is fixedly installed. The front plate 7 is fixed by bolts and connects the two vertical plates 3 together. On the outer wall of one side of the front plate 7, a transverse plate 8 is fixedly installed. On the top of the transverse plate 8, a fixed bin 9 is fixedly installed. The transverse plate 8 is fixed by welding. Both sides of the fixed bin 9 are provided with openings, so that its cross-section presents a shape like the Chinese character "mouth". One end of the cable 6 penetrates through the fixed bin 9.

[0025] A lower pressure platform 10 is slidably installed inside the fixed chamber 9. The bottom of the lower pressure platform 10 and the bottom inner wall of the fixed chamber 9 are both set as arc-shaped surfaces, and buffer pads 13 are set inside the arc-shaped surfaces to protect the cable 6 and avoid rigid compression. A threaded cylinder 11 is fixedly installed through the top of the fixed chamber 9. A drive shaft 12 is threadedly installed on the threaded cylinder 11. The drive shaft 12 is a common threaded rod. A rotating wheel is fixedly installed at the top of the drive shaft 12. The bottom end of the drive shaft 12 is rotatably connected to the top of the lower pressure platform 10.

[0026] A rotating bearing is fixedly sleeved at the bottom end of the drive shaft 12, and a bearing cylinder is fixedly installed at the top end of the lower pressure platform 10. The outer wall of the rotating bearing is fixedly connected to the inner wall of the bearing cylinder. Figure 2 As shown, slotted openings are provided on both inner walls of the fixed chamber 9, and limit rods are vertically fixedly installed in both slots. Limit blocks are fixedly installed on both outer walls of the lower pressure platform 10. The two limit rods pass through the two limit blocks and are slidably connected to them. Through the setting of the rotating bearing and the limit rods, the lower pressure platform 10 will not rotate with the drive shaft 12, but can only move vertically up and down with the drive shaft 12 under the side effect of the thread.

[0027] Protective covers 14 are fixedly installed on the outer walls of the two vertical plates 3 on opposite sides. The protective covers 14 are annular bowl-shaped with their openings facing outwards. The rotating rod 4 extends into the protective cover 14 and is rotatably connected to it. The two return mechanisms are respectively installed inside the two protective covers 14. The return mechanisms mainly prevent damage to the connection points when the cable 6 is subjected to rigid tension. Dust covers 15 are installed on both protective covers 14. The dust covers 15 close the openings of the protective covers 14 and are screwed onto the openings of the protective covers 14 by means of threads.

[0028] Each of the aforementioned return-line mechanisms includes a rotating disk 16, which is fixedly mounted on one end of the rotating rod 4. The rotating disk 16 is located inside the protective cover 14, and its center is aligned with that of the rotating rod 4. A fixing plate 17 is fixedly mounted on one inner wall of the protective cover 14, and one side of the fixing plate 17 extends through the rotating disk 16. Figure 3 , Figure 4 and Figure 5As shown, a clearance groove 18 is provided on one outer wall of the rotating disk 16. The clearance groove 18 is semi-circular, and its trajectory is coaxial with that of the rotating disk 16. The fixing plate 17 passes through the clearance groove 18 and does not contact the inner wall of the clearance groove 18. A positioning plate 19 is fixedly installed on one outer wall of the rotating disk 16. The positioning plate 19 and the fixing plate 17 are symmetrically arranged based on the center of the rotating disk 16. A crank 20 is fixedly installed on the positioning plate 19. One end of the crank 20 passes through the fixing plate 17 and is slidably connected to it. Both the crank 20 and the clearance groove 18 are coaxial with the rotating rod 4. To prevent the crank 20 from separating from the fixing plate 17, a plug is fixedly installed on one end of the crank 20. A return spring 21 is sleeved on the crank 20. The top end of the return spring 21 is fixedly connected to the positioning plate 19, and the bottom end of the return spring 21 is fixedly connected to the fixing plate 17.

[0029] Two fastening bolts 2 are movably installed on the top of the support plate 1. The two fastening bolts 2 are located on the opposite side of the two vertical plates 3. In actual use, the support plate 1 is fixedly installed in a suitable position by the two fastening bolts 2.

[0030] The working principle of the high-voltage cable bracket fixing device provided by this utility model is as follows:

[0031] When performing high-voltage cable wiring operations, the worker first uses two fastening bolts 2 to fix the support plate 1 in a suitable position inside the power tower. Then, the cable 6 is wound around the winding wheel 5. After winding, one end of the cable is passed through the fixing chamber 9 and placed on the arc-shaped surface on the inner wall of the bottom of the fixing chamber 9. Then, the drive shaft 12 can be rotated. The rotation of the drive shaft 12 will gradually move downward due to the side effect of the thread. At this time, the pressure plate 10 is limited and can only move downward with the drive shaft 12, thereby achieving the clamping effect on the cable 6. In actual use, after the fixing chamber 9 clamps the cable 6, a section of cable needs to be reserved between the fixing chamber 9 and the winding wheel 5 so that the part between the two is in a slack state.

[0032] The end of the cable 6 that is clamped by the pressure plate 10 is finally connected to the power tower, while the other end that is not clamped is laid horizontally in the air to the adjacent power tower.

[0033] In daily power transmission, if birds or other animals land on cable 6, the weight of the birds will gradually pull the cable 6 across the air, creating a pulling effect on the fixed clamps at both ends of the cable 6. During this pulling process, the cable 6 will drive the winding wheel 5 to rotate, which in turn will drive the rotating rod 4 to rotate, further driving the rotating disk 16 inside the protective covers 14 on both sides to rotate. As the rotating disk 16 rotates, it will further drive the positioning plate 19 to rotate, which in turn will drive the crank 20 to rotate, thus gradually reducing the angle between the positioning plate 19 and the fixed plate 17. Furthermore, as the positioning plate 19 rotates, it will further compress the return spring 21, causing the return spring 21 to gradually enter a compressed and energy-storing state.

[0034] At the same time, the rotation of the winding wheel 5 will release the cable 6 wound on the winding wheel 5. Thus, when it is pulled by an external force, the impact of the pull is reduced by the return spring 21 and the release of a small section of cable 6. After the external force disappears, the return spring 21 will gradually return to its initial state under the action of the elastic force, and the winding wheel 5 will rewind the released cable 6.

[0035] Compared with related technologies, the high-voltage cable support fixing device provided by this utility model has the following advantages:

[0036] This utility model provides a high-voltage cable support fixing device. By setting up a return mechanism, when the cable 6 laid in mid-air is pulled by external force, a small section of the cable 6 is released by the winding wheel 5 and the return spring 21 is compressed by force, which effectively reduces the impact of external force on the fixing clamping points at both ends of the cable 6 and effectively disperses the impact force, thereby effectively protecting the clamping points at both ends of the cable 6. The whole process is simple and convenient, and can effectively protect the cable, avoid the reduction in service life caused by long-term pulling and wear at the connection, and reduce the danger of cable breakage.
