Description

Technical Field

[0001] The present application relates to the technical field of power metering equipment protection equipment, and more specifically, to a power metering equipment protection device. Background Art

[0002] The essence of power marketing is to adjust the demand level and time of the power market, meet the users' reasonable power consumption requirements with good service quality, achieve mutual coordination between power supply and demand, establish a partnership between power companies and users, and encourage users to actively change their consumption behavior and power consumption methods, improve power efficiency, and thus increase the benefits of the enterprise. Electric energy metering equipment is a metering instrument used to measure and record power generation, power supply, plant power consumption, line loss power and user power consumption.

[0003] The document with prior art publication number CN216003455U provides a protective device for electric power marketing metering equipment. The device can play a shock-absorbing role during transportation through the cooperation between an outer protective box, an electric power metering box, a first slide groove, a telescopic rod, a pulley, and a first spring, thereby preventing damage to the electronic equipment inside the outer protective box; through the cooperation between the servo motor, the threaded rod, the drive block, the support rod, and the moving wheel, it is convenient to take out the electric power metering box during maintenance.

[0004] Although the above-mentioned prior art scheme can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the above-mentioned prior art power marketing metering equipment protection device is in use, the power metering box is cooled by the heat dissipation holes opened on the side wall of the outer protection box, so that the power metering box can operate normally. However, the above-mentioned heat dissipation method through the heat dissipation holes makes it easy for dust and impurities in the external environment to enter the outer protection box through the heat dissipation holes and accumulate on the surface of the power metering box. Since the power metering device installed inside the outer protection box will generate heat during operation, if the surface of the power metering box affects the normal heat dissipation of the power metering device, long-term high-temperature operation may accelerate the aging speed of the electronic components inside the power metering device, affect the stability of the operation of the power metering device, and shorten the service life of the power metering device.

[0005] In view of this, we propose a protective device for electric power metering equipment. Summary of the invention

[0020] 3. Beneficial effects

[0021] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0022] 1. The electric power metering equipment protection device can facilitate the heat dissipation of the electric power metering equipment body in operation by means of a dustproof structure arranged at the heat dissipation port, and can also effectively prevent dust in the external environment from entering the outer protection box and being adsorbed on the surface of the electric power metering equipment body, thereby ensuring that the normal heat dissipation of the electric power metering equipment body is not affected when it is in operation.

[0023] 2. When it is necessary to regularly clean the dust adhered to the surface of the stainless steel dustproof net, first turn on the vacuum pump on the dustproof structure, and then turn on the electric push rod. While the electric push rod drives the negative pressure cover to reciprocate up and down, the elastic scraper bar that is tightly attached to the surface of the stainless steel dustproof net and has elasticity will scrape off the dust adhered to the surface of the stainless steel dustproof net to ensure the heat dissipation effect of the stainless steel dustproof net on the main body of the power metering equipment in operation. The scraped dust is continuously sucked into the inner dust removal cylinder under the action of the negative pressure suction of the vacuum pump. The holes on the end of the inner dust removal cylinder intercept and filter the dust, so that the dust is uniformly collected inside the inner dust removal cylinder, which improves the cleaning efficiency of the stainless steel dustproof net and prevents the elastic scraper bar from scraping off the dust on the surface of the stainless steel dustproof net and directly escaping into the air to pollute the environment.

[0024] 3. The elastic scraper is made of elastic rubber material. While scraping off the dust adhering to the surface of the stainless steel dustproof net, it can also effectively prevent the surface of the stainless steel dustproof net from being scratched.

[0025] 4. Unscrew the thread of the sleeve on the end of the connecting pipe, and then unscrew the inner dust removal cylinder from the inside of the sleeve, so that people can easily clean the dust collected in the inner dust removal cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
