Intelligent electric meter with self-cleaning function

By designing an automatic cleaning system on smart meters, the meshing motion of scrapers and toothed blocks solves the problem of increased workload caused by dust accumulation on the observation window of outdoor meters. This achieves automatic cleaning and protection of the transparent window, improving the convenience of meter reading and maintenance.

AI Technical Summary

Technical Problem

The observation windows of existing outdoor smart meters are blurred due to the accumulation of dust and insect excrement, which increases the workload of maintenance personnel and affects the convenience of meter reading and equipment maintenance.

Method used

A smart meter with a self-cleaning function was designed. By setting up a scraper and a cleaning rack, the scraper and toothed blocks are driven by a moving motor to slide on the surface of the observation window, so as to automatically clean dust and hardened insect excrement. Combined with the meshing of the rack and the limiting groove, the impurities between the toothed blocks are automatically cleaned, and the residual impurities are cleaned by the airflow of the piston and the sealed cavity.

Benefits of technology

It enables automatic cleaning of the meter's observation window, reducing the workload of manual cleaning, maintaining the clarity of the observation window, avoiding meter reading errors and untimely fault identification caused by dust and dirt, and protecting the transparent surface of the observation window from wear.

Abstract

The application belongs to the technical field of electrical appliances, and particularly relates to a smart electric meter with a self-cleaning function, which comprises an electric meter, the surface of the electric meter is provided with an observation window, one side of the observation window is provided with a cleaning frame, the cleaning frame and the surface of the electric meter are in sliding connection, a moving plate is in sliding connection with the inside of the cleaning frame, one side of the moving plate is in sliding connection with a scraper, the lower surface of the scraper is in close contact with the surface of the electric meter, the surface of the scraper is provided with a plurality of tooth blocks, one side of the scraper is provided with a rack, the rack is in fixed connection with the inner wall of the cleaning frame, and the rack and the tooth blocks are in meshing connection. The device drives the scraper in the cleaning frame to move through a lead screw, thereby automatically cleaning the impurities on the observation window of the electric meter, avoiding the observation window of the outdoor electric meter from being easy to accumulate dust, causing the observation window to be unclear, making the meter reading data be misread, the equipment fault indicator light be unable to be recognized, and thus the problem of the electric meter fault being not found in time.
