Description

Technical Field

[0001] This utility model relates to the field of voltage protection technology, specifically an overvoltage protector. Background Technology

[0002] The combined overvoltage protector is a high-performance overvoltage absorption device, an advanced protective electrical appliance that limits lightning overvoltages and switching overvoltages. It is mainly used to protect the insulation of electrical equipment such as generators, transformers, switches, busbars, motors, and parallel capacitor banks from overvoltage damage. It provides effective protection against both phase-to-phase and phase-to-ground overvoltages.

[0003] To achieve rapid heat dissipation, existing combined overvoltage protectors typically install heat sinks on the surface of the protector's casing, thereby increasing the heat dissipation area and improving the heat dissipation effect. However, during long-term use, a large amount of dust will gradually accumulate on the surface of the heat sink. As the dust accumulates, it will gradually affect the heat dissipation effect of the heat sink. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

[0004] The purpose of this invention is to provide an overvoltage protector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An overvoltage protector includes a base and multiple overvoltage protector bodies mounted on the base. Multiple heat sinks are installed on the overvoltage protector bodies. The protector also includes a cleaning mechanism. The cleaning mechanism includes an arched frame movably mounted on the base and a drive assembly for driving the arched frame to move horizontally. A rotating shaft is rotatably mounted on the arched frame. The rotating shaft is driven by a first motor mounted on the arched frame. An eccentric rod is fixedly mounted on the rotating shaft. A cleaning rod is mounted on the eccentric rod, and a cleaning brush is mounted on the cleaning rod.

[0007] As a further embodiment of this utility model: the driving assembly includes a screw and a guide rod installed side by side in the base. The base is symmetrically provided with strip grooves. The screw is rotatably disposed in one of the strip grooves and is driven by a second motor disposed on the side of the base. A matching screw sleeve is installed on the screw. The guide rod is fixedly installed in the other strip groove, and a sliding sleeve is movably installed on the guide rod. The arched frame is fixedly installed on the screw sleeve and the sliding sleeve.

[0008] As a further embodiment of this utility model: the sweeping rod is rotatably mounted, and a gear is fixedly installed at the top of the sweeping rod; an internal gear ring is also fixedly installed on the top surface of the inner cavity of the arched frame, and the internal gear ring meshes with the gear.

[0009] As a further embodiment of this utility model: a pull-out box is also installed inside the base via a slide rail, and multiple cooling fans are installed on the pull-out box.

[0010] As a further embodiment of this utility model, the top surface of the inner cavity of the base is also equipped with multiple heat dissipation teeth.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model, by setting up a cleaning mechanism, drives the arched frame to move to the positions of multiple overvoltage protectors in succession. Then, the first motor drives the rotating shaft to rotate, which in turn drives the eccentric rod and the sweeping rod to rotate together. As the sweeping rod revolves around the rotating shaft, it can rotate around the overvoltage protector body. With the help of the cleaning brush on the sweeping rod, the heat sink can be cleaned, solving the problem of dust accumulation on the heat sink affecting heat dissipation in the prior art.

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] Example 1

[0019] Please see Figure 1-3An overvoltage protector includes a base 1 and multiple overvoltage protector bodies 2 mounted on the base 1. Multiple heat sinks 3 are mounted on the overvoltage protector bodies 2. The protector also includes a cleaning mechanism. The cleaning mechanism includes an arched frame 4 movably mounted on the base 1 and a drive assembly for driving the arched frame 4 horizontally. A rotating shaft 5 is rotatably mounted on the arched frame 4. The rotating shaft 5 is driven by a first motor 6 mounted on the arched frame 4. An eccentric rod 7 is fixedly mounted on the rotating shaft 5. A cleaning rod 8 is mounted on the eccentric rod 7, and a cleaning brush 9 is mounted on the cleaning rod 8. By setting up the cleaning mechanism, after the drive assembly drives the arched frame 4 to move sequentially to the positions of the multiple overvoltage protector bodies 2, the first motor 6 drives the rotating shaft 5 to rotate. The rotating shaft 5 can drive the eccentric rod 7 and the cleaning rod 8 to rotate together. During the revolution of the cleaning rod 8 around the rotating shaft 5, it can rotate around the overvoltage protector bodies 2. Combined with the cleaning brush 9 on the cleaning rod 8, the heat sinks 3 can be cleaned, solving the problem of dust accumulation on the heat sinks 3 affecting heat dissipation in the prior art.

[0020] It is necessary to explain that, in order to avoid motion interference between the cleaning rod 8 and the cable when the cleaning rod 8 rotates around the voltage protector body 2, the cleaning of the heat sink 3 can be achieved by controlling the first motor 6 to rotate in both directions.

[0021] Specifically, the drive assembly includes a screw 10 and a guide rod 13 installed side by side in the base 1. The base 1 has symmetrically opened strip grooves 12. The screw 10 is rotatably disposed in one of the strip grooves 12 and is driven by a second motor 11 disposed on the side of the base 1. A screw sleeve 14 adapted to the screw 10 is installed on the screw 10. The guide rod 13 is fixedly installed in the other strip groove 12, and a sliding sleeve 15 is movably installed on the guide rod 13. The arched frame 4 is fixedly installed on the screw sleeve 14 and the sliding sleeve 15.

[0022] Preferably, the cleaning rod 8 is rotatably mounted, and a gear 16 is fixedly installed at the top of the cleaning rod 8. An internal gear ring 17 is also fixedly installed on the top surface of the inner cavity of the arched frame 4. The internal gear ring 17 meshes with the gear 16. When the cleaning rod 8 rotates around the voltage protector body 2, the meshing of the gear 16 and the internal gear ring 17 can drive the rotation of the cleaning rod 8. Through the cooperation of rotation and revolution, the cleaning effect of the heat sink 3 is further improved.

[0023] Example 2

[0024] This embodiment is an improvement on embodiment 1, specifically as follows:

[0025] Please see Figure 1 and Figure 3The base 1 is also equipped with a pull-out box 18 via a slide rail. Multiple cooling fans 19 are installed on the pull-out box 18. By setting up the pull-out box 18, it is convenient to inspect and maintain the cooling fans 19, which further improves the practicality of the heat dissipation structure.

[0026] In addition, to further accelerate the heat dissipation of the base 1, multiple heat dissipation teeth 20 are also installed on the top surface of the inner cavity of the base 1 in this embodiment.
