Electric energy meter with internal dust removal function

Abstract

The invention discloses an electric energy meter with an internal dust removal function, and relates to the technical field of electric energy meters, the electric energy meter comprises a main shell, a cleaning assembly is mounted in the main shell, inner supports are fixedly mounted at four corners in the main shell, the multiple inner supports are jointly connected with an inner main body, a circulation assembly is mounted on one side of the main shell, and a dust removal assembly is mounted on the other side of the main shell. The cleaning assembly comprises a reciprocating lead screw rotationally connected to the main shell through a bearing, a matched shaft block is arranged on the reciprocating lead screw, brush rods are rotationally connected to the upper end and the lower end of the shaft block, and a driving opening is formed in one side of the main shell. By means of the arranged cleaning assembly, a shaft block can be driven to move back and forth in a reciprocating mode through rotation of a reciprocating lead screw in cooperation with the limiting effect of a limiting side sliding rod, and when two arranged brush rods move back and forth along with the shaft block, a gear can be engaged with a toothed bar, so that the two brush rods can rotate rapidly; and therefore, the interior of the main shell is cleaned.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to an electric energy meter with an internal dust removal function. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, or a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. When using the energy meter, it should be noted that in the case of low voltage (not exceeding 500 volts) and small current (tens of amps), the energy meter can be directly connected to the circuit for measurement. In the case of high voltage or high current, the electric energy meter cannot be directly connected to the line, and needs to be used with a voltage transformer or a current transformer. After the electric energy meter is used for a long time, a lot of dust is easy to adhere to the inside, which will affect the service life of the electric ene...

Problems solved by technology

[0005] However, the above-mentioned invention has the following shortcomings: the above-mentioned patent mainly relies on the cooperation of the fan and the filter screen installed on the dust collector to realize the dust removal treatment of the electric energy meter, but it lacks the brushing of the internal structure of the electric energy meter, resulting in the removal of dust The effect is not ideal, and it is easy to have a lot of dust residue, so there are certain limitations
