Building ventilation and effective dustproof ventilation pipe based on ventilation quantity self-adjustment

Abstract

The invention provides a building ventilation and effective dustproof ventilation pipe based on ventilation quantity self-adjustment. The building ventilation and effective dustproof ventilation pipe comprises a body, a fixing groove is formed in the inner wall of the body, a shell is fixedly installed on the inner wall of the fixing groove, a spring mechanism is installed in the shell, the right end of the spring mechanism is fixedly connected with a movable part, and a wind gathering mechanism is fixedly mounted at the lower end of the movable part. According to the building ventilation and effective dustproof ventilation pipe based on ventilation quantity self-adjustment, when ventilation is finished, a fixed part is pushed to return to an initial position through mounting springs, so that movable connecting rods drive movable baffles to form a closed state, and external dust particles are effectively prevented from coming in through closing between the movable baffles; and therefore the situation that the interior of the ventilation pipe is crowded and blocked due to coming-in of sundries, and consequently normal use of the ventilation pipe is affected is effectively avoided, and the equipment achieves the effect of effective dust prevention when ventilation is not needed.

Description

technical field [0001] The invention belongs to the technical field of building ventilation, and in particular relates to a ventilation pipe for building ventilation based on self-adjustment of ventilation volume and effective dust prevention. Background technique [0002] Construction refers to the assets made by artificial construction, which belongs to the category of fixed assets, including houses and structures. Houses refer to projects for people to live, work, study, produce, operate, entertain, store items and conduct other social activities. Buildings differ from buildings in structures, which refer to engineering buildings other than houses, such as walls, roads, dams, wells, tunnels, water towers, bridges, and chimneys.

AI Technical Summary

Problems solved by technology

[0003] Nowadays, with the rapid development of my country's construction industry, building ventilation ducts are widely used in the construction industry, and building ventilation ducts are places where a large amount of air circulates and gathers, and traditional ventilation ducts cannot be used because the vents are open for a long time Open when not in use, and automatically close when not in use. Due to the long-term air circulation, solids such as smoke and dust remain in the pipeline, so it is easy to cause blockage of the pipeline, which affects its ventilation effect and normal use, so it cannot satisfy users. needs, therefore, it is necessary to further improve
