[0002] High-voltage distribution cabinet refers to an electrical product with a voltage level of 3.6kV to 550kV, which plays the role of switching, controlling or protecting in power generation, transmission, distribution, power conversion and consumption of power systems. It mainly includes high-voltage circuit breakers, high-voltage disconnectors and grounding switches, high-voltage load switches, high-voltage automatic reclosing and disconnecting devices, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switch cabinets. Cables need to be connected to electrical equipment inside the distribution cabinet.

Under the influence of gravity, the connection between the cables and the electrical equipment will not be tight, resulting in poor contact or even short circuit of the cables, seriously affecting the safe operation of the equipment. Traditional equipment lacks a fixed protection mechanism for the cables. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 A wiring protection mechanism for a high-voltage distribution cabinet comprises a fixed plate 1, a limiting hole 2 is provided on the outer wall of the fixed plate 1, an L-shaped plate 3 is installed on the top of the fixed plate 1, a limiting plug rod 4 is fixedly installed on the outer wall of the L-shaped plate 3, a fixed cylinder 5 is fixedly installed on the outer wall of the L-shaped plate 3, a telescopic spring 6 is installed in the inner cavity of the fixed cylinder 5, a telescopic rod 8 is movably sleeved in the inner cavity of the fixed cylinder 5, a limiting rod 7 is fixedly installed on the outer wall of the telescopic rod 8, a supporting plate 9 is fixedly installed on the outer wall of the supporting plate 9, a rotating wheel 10 is rotatably connected to the inner wall of the rotating wheel 10, a card slot 11 is provided on the outer wall of the rotating wheel 10, a fixing rod 12 is fixedly installed on the top of the supporting plate 9, a card plate 13 is rotatably connected to the outer wall of the fixing rod 12, a tension spring 14 is fixedly installed on the top of the supporting plate 9, and a cable 15 is installed in the inner cavity of the fixed plate 1.

[0022] By means of the telescopic spring 6 arranged in the inner cavity of the fixed tube 5 and the telescopic rod 8 movably sleeved in the inner cavity of the fixed tube 5, the telescopic rod 8 can move in the inner cavity of the fixed tube 5 under the action of the telescopic spring 6, and can move forward under the push of the telescopic spring 6, so that the telescopic rod 8 drives the movement of the support plate 9 and the rotating wheel 10, so that the outer wall of the rotating wheel 10 is tightly attached to the outer wall of the cable 15, which has a good fixing and protecting effect on the cable 15.

[0023] In a preferred embodiment, a sliding groove is formed on the outer wall of the fixing tube 5 , and the distance between the inner walls of the sliding groove matches the outer wall diameter of the limiting rod 7 .

[0024] Through the sliding groove opened on the outer wall of the fixed tube 5, when the telescopic rod 8 moves under the push of the telescopic spring 6, the limiting rod 7 will move along the sliding groove, and the telescopic rod 8 will be limited under the action of the sliding groove and the limiting rod 7, so that the telescopic rod 8 can only move back and forth in the inner cavity of the fixed tube 5, thereby realizing the protection and fixation of the cable 15.

[0025] In a preferred embodiment, the outer wall shape of the clamping plate 13 away from the fixing rod 12 matches the inner wall shape of the clamping slot 11 , and the outer wall of the tension spring 14 away from the supporting plate 9 is connected to the outer wall of the clamping plate 13 .

[0026] By means of the clamping plate 13 and the tension spring 14 arranged on the top of the support plate 9, the outer wall of the clamping plate 13 and the inner wall of the slot 11 can be fitted together under the action of the tension spring 14. At this time, under the action of the clamping plate 13, the rotating wheel 10 can only rotate unidirectionally outward and cannot rotate inward, so that the cable 15 can only move upward under the action of the rotating wheel 10 and the slot 11, and cannot move downward.

[0027] In a preferred embodiment, there are two clamping plates 13 , and the two clamping plates 13 are respectively installed on both sides of the top of the support plate 9 .

[0028] By arranging the clamping plates 13 on both sides of the top of the support plate 9, the rotating wheel 10 can be fixed at the same time under the action of the clamping plates 13 on both sides, so that the rotating wheels 10 on both sides can only rotate outward at the same time, and then the rotating wheel 10 can only move upward and cannot move downward.

[0029] In a preferred embodiment, a pull rod is fixedly mounted on the top of the clamping plate 13 , and the outer wall diameter of the telescopic rod 8 matches the inner wall diameter of the fixed tube 5 .

[0030] By setting a pull rod at the top of the clamping plate 13, the clamping plates 13 on both sides can be rotated under the action of the pull rod, thereby releasing the lock of the rotating wheel 10, which is very convenient. Moreover, the telescopic rod 8 can move back and forth well in the inner cavity of the fixed tube 5 under the action of the telescopic spring 6.

[0031] In a preferred embodiment, the outer wall of the rotating wheel 10 is fixedly equipped with an anti-skid pad, and the anti-skid pad is made of natural rubber.

[0032] By providing an anti-skid pad on the outer wall of the rotating wheel 10, when the rotating wheel 10 is fitted onto the outer wall of the cable 15 under the action of the telescopic spring 6 and the telescopic rod 8, the friction between the rotating wheel 10 and the cable 15 can be increased under the action of the anti-skid pad, so that the outer wall of the cable 15 can better fit onto the outer wall of the rotating wheel 10.

[0033] Working principle: During the use of the above-mentioned device, when the device is needed to fix and protect the cable 15, the limiting plug rod 4 is first inserted into the inner cavity of the limiting hole 2. At this time, the L-shaped plate 3 can be fixed on the top of the fixing plate 1 under the action of the limiting plug rod 4 and gravity, and then the support plate 9 is pulled to make the support plate 9 move slightly outward, and the cable 15 can be passed through the bottom of the rotating wheel 10. At this time, the support plate 9 can be loosened, and the cable 15 is continuously pulled upward until the length of the cable 15 meets the length of the wiring, and the cable 15 is wired. At this time, the cable 15 can be fixed under the action of the rotating wheel 10 and the card plate 13. Under the action of gravity, the cable 15 will tend to move downward. If the cable 15 wants to move downward, the rotating wheel 10 must rotate, but at this time, the rotating wheel 10 cannot rotate under the action of the card slot 11 and the card plate 13, thereby fixing the cable 15 and preventing the cable 15 from falling downward under the action of gravity during use, thereby better playing a protective role.

[0034] Although the 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.
