Relay drying and dust removing device

Abstract

The invention discloses a relay drying and dust removing device. The relay drying and dust removing device comprises a machine frame, wherein a movable drying assembly is arranged at the inner bottomend of the machine frame; the movable drying assembly comprises a first motor fixedly installed at the bottom end of the machine frame, wherein the tail end of the first motor is in power connection with a first rotating shaft extending up and down; the upper end of the first rotating shaft is fixedly connected with a first bevel gear, wherein the upper end of the first bevel gear is engaged witha second bevel gear; and a second rotating shaft extending front and back is fixedly installed in the center of the second bevel gear, wherein the second rotating shaft is fixedly connected with a first transmission wheel located on the rear side of the second bevel gear. According to the relay drying and dust removing device, when the device works, a relay is dried through moving the drying assembly to prevent water inflow short circuit, the relay is fixed through two limiting plates, and after the relay is completely fixed, the device sweeps and collects dust on the relay, in this way, the dust on the relay can be effectively treated, the working environment is improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of electric switches, in particular to a relay drying and dust removal device. Background technique [0002] A relay is an electrical control device, which is an electrical appliance that makes a predetermined step change in the controlled quantity in the electrical output circuit when the change of the input quantity (excitation quantity) reaches the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automated control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. After the electromagnetic system and the contact system of the relay are assembled, the two parts need to be dedusted to remo...

AI Technical Summary

Problems solved by technology

After the electromagnetic system and contact system of the relay are assembled, the two parts need to be dedusted to remove the possible influence of dust on the relay. However, the existing method is to dedust it with an air blowing nozzle, which will make the dust Diffuse in the air, which is harmful to health, and the dust removal effect is very poor. In addition, the waterproof performance of the relay is poor, which may cause a short circuit of the relay and affect the use
