A cleaning device for teaching electrical appliances

Abstract

The invention discloses an electrical appliance instrument cleaning device for teaching. The electrical appliance instrument cleaning device for teaching comprises a housing, a gas blowing system anda rotating device, wherein the gas blowing system comprises a gas source, a primary gas pipeline and a branch gas pipeline; the branch gas pipeline extends into the housing; the rotating device comprises a rotating frame, a first rack and a drive device; the first rack is connected to the inner wall of the housing; the output end of the drive device is connected to the rotating frame; the rotatingframe comprises upper and lower ring-shaped plates; a first gear is arranged between the two ring-shaped plates; the first gear is engaged with the first rack; the first rotary shaft of the first gear is rotatably connected to the two ring-shaped plates; and the lower end of the first rotary shaft is equipped with a connecting mechanism. Gas in the gas source sequentially passes through the primary gas pipeline, and the branch gas pipeline to enter the housing; and electrical appliance instruments revolute along with the rotating frame, and also automatically rotate along with the first rotary shaft, so that the electrical appliance instruments can be comprehensively and quickly cleaned, and therefore, cleaning efficiency is high and the cleaning effect is good.

Description

technical field

[0001] The invention relates to the technical field of electrical instrument cleaning, in particular to a teaching electrical instrument cleaning device. Background technique

[0002] In electromechanical teaching, a large number of experiments are needed to help students better understand electrical principles, mechanical movement processes and electromechanical linkage processes. Therefore, a large number of electronic instruments are required in the laboratory, such as indicating instruments, frequency meters, phase meters, and synchronization indicators. Instruments, resistance measuring instruments, and electronic instruments commonly used in electrical measurement, etc. Many instruments need to be handed in during use, but electronic instruments will have a lot of dust after long-term use, especially some electronic instruments that have been used for a long time Placed in corners and warehouses, too much dust will cause failure of electrical instrument...
