Automatic dust removal environment-friendly device used for school teaching blackboard

Abstract

The invention relates to the technical field of teaching, and discloses an automatic dust removal environment-friendly device used for a school teaching blackboard. The device comprises a machine shell, chain wheels are movably connected in the machine shell, chains are movably connected to the exteriors of the chain wheels, and rotating shafts are movably connected to the exteriors of the chains.Under the interaction of the chain wheels, the chains, the rotating shafts, sliding rails, photosensitive assemblies, detection assemblies, sliding blocks, sliding rods, a fixed frame, U-shaped magnetic plates, electromagnets, rotating plates, dust collection plates, sweeping brushes, electromagnetic pumps and collection tanks, wiping dust can be automatically and cleanly collected in the collection tanks under mutual cooperation of the dust collection plates and the collection tanks; and the situation that lungs and bronchi are diseased due to the fact that teaching staff inhale a large amount of dust is avoided, the labor intensity of teaching of the teaching staff is reduced, the sanitation quality of the teaching environment is further improved, and meanwhile the device conforms to the environmental protection concept advocated by people.

Description

technical field [0001] The invention relates to the technical field of teaching, in particular to an automatic dust removal and environmental protection device for school teaching blackboards. Background technique [0002] The teaching blackboard commonly used in teaching has the advantages of hard surface and no reflection. The commonly used teaching blackboard surface is generally made of magnetic color-coated steel plate, and the thickness of the board surface is mostly between 0.2MM-0.4MM. Because the magnetic color-coated steel plate has Grinding, no falling off, no fading, good writing feel, clear handwriting, easy to write and erase, so it is widely used in teaching blackboards. According to the structure, teaching blackboards are divided into flat blackboards, curved blackboards, and movable writing boards with brackets. However, the existing teaching blackboard must be manually wiped by the teaching staff using blackboard erasers and other utensils after the teachin...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automatic dust removal and environmental protection device for school teaching blackboards, which has the advantages of automatic erasing, automatic dust collection, environmental protection and sanitation, and solves the problem that the existing teaching blackboards cannot be completed by teaching staff. Finally, the teaching staff must manually use blackboard erasers and other utensils to erase it, which wastes a lot of teaching time for teaching staff in teaching. At the same time, wiping the blackboard will bring a lot of dust. Causes problems like dust collection in the lungs and inflammation of the bronchial tubes
