[0002] Power distribution equipment refers to the general term for various types of equipment used for power transmission and distribution in power systems. The following are some common power distribution equipment. In the process of building a power system, high-voltage grounding switches are often required.

[0003] After searching, the patent number is CN218866968U, and the name is a straight-rod high-voltage grounding switch, including a mounting base, a support insulator, a grounding static contact, a grounding knife assembly, a driving mechanism, a limiting mechanism and a grounding knife moving contact. Through research and analysis, it is found that although the grounding knife moving contact has the advantage of more stable closing, it still has the following disadvantages to a certain extent.

[0004] For example, the straight-pole high-voltage grounding switch mentioned above usually does not have a quick-detachable dust removal device during use, which means that the user cannot manually remove dust from the surface of the device before use, which may affect the insulation safety of the device body due to dust accumulation. In order to solve the above technical problems, we have designed a high-voltage grounding switch. Utility Model Content

[0005] The utility model aims to provide a high-voltage grounding switch, which has the advantage of quick-detachable manual dust raising and removing function, and solves the problem that manual dust raising and removing cannot be performed before use and the switch cannot be quickly disassembled when needed.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-voltage grounding switch, comprising a mounting frame, a high-voltage switch body is arranged on the front side of the mounting frame, an air inlet and outlet mechanism is arranged on the rear side of the mounting frame, the air inlet and outlet mechanism comprises a shell, a fixed horizontal plate is welded on the front side of the shell, a gas circulation mechanism is arranged on the left side of the shell, the gas circulation mechanism comprises a filter shell and a first connecting pipe, the left side of the filter shell is connected to the shell, a fixed vertical plate is welded on the rear side of the fixed horizontal plate, an active buckle is welded on the rear side of the fixed vertical plate, a nozzle replacement mechanism is arranged on the top of the fixed vertical plate, and the nozzle replacement mechanism comprises a filter ventilation shell.

[0009] Preferably, support legs are welded to both the front and rear sides of the bottom of the ventilation pipe network, and support seats are welded to the bottom of the support legs.

[0010] Preferably, a two-way pump is connected to the left side of the shell by bolts, the rear side of the two-way pump is connected to a second pipe, the side of the second pipe away from the two-way pump is connected to the two-way pump, the top of the two-way pump is connected to a first pipe, and the side of the first pipe away from the two-way pump is connected to the first connecting pipe.

[0011] Preferably, a threaded connection pipe is welded on the top of the first connecting pipe, a threaded connection sleeve is provided on the surface threaded sleeve of the threaded connection pipe, and the top of the threaded connection sleeve is connected to the bottom of the filter ventilation shell.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model is provided with a high-voltage switch body, a fixed vertical plate, a threaded connection sleeve, a filter ventilation shell, a first connecting pipe, a second connecting pipe, a ventilation pipe network, a shell and a fixed horizontal plate for coordinated use. During use, the first connecting pipe can be manually pulled out, and then aligned with the position on the surface of the high-voltage switch body that needs dust removal, and then the bidirectional pump is started through the external controller. The bidirectional pump draws external dust and impurities through the ventilation pipe network to the second connecting pipe, and then sends them to the inner cavity of the shell. After the impurities are filtered out by the filter shell, they are sent to the first pipe through the second pipe, and then sent to the filter ventilation shell through the first connecting pipe for spraying, so as to carry out dust removal.

The utility model is provided with an active buckle, a slide rail, a guide groove, a first pipe, a two-way pump, a second pipe, a filter shell, a dust collection drawer and a guide block for coordinated use. During use, the fixed cross plate can be manually pushed to move the whole device to the left until the guide block is separated from the guide groove, thereby completing the disassembly of the device. In daily use, the user can also reversely drive the two-way pump to filter and extract the outside air through the filter ventilation shell to the first connecting pipe, and then send it to the inner cavity of the filter shell through the first pipe and the second pipe, and then send it to the inner cavity of the second pipe through the shell, and finally spray it out through the ventilation pipe network, thereby accelerating the flow rate of the surrounding air to quickly dissipate the heat of the device body.
