Device capable of automatic replacement of anti-insect mesh

Abstract

The invention provides a device capable of automatic replacement of an anti-insect mesh. The device comprises a box body, mesh gauze, an upper round shaft, a lower round shaft, a driving mechanism, two limiting rods, a differentia pressure detection mechanism and a controller, wherein the box body is hollow inside, and an air inlet and an air outlet are formed relatively in centers of the front side and the back side; the upper round shaft and the lower round shaft are disposed in the box body in a rotatable manner along left and right directions; one end of the lower round shaft passes through the box body and extends to outside of the box body and is in transmission connection to the driving mechanism disposed on the box body; the two limiting rods are fixedly disposed in the box body along left and right directions; clearance used for passing of the mesh gauze is formed between each limiting rod and the inner wall of the front side of the box body; one end of the mesh gauze is woundon the upper round shaft, and the other end is wound on the lower round shaft after successively bypassing the clearance between each of the two limiting rods and the inner wall of the front side ofthe box body; the differential pressure detection mechanism is disposed on the box body; and the driving mechanism and the differential pressure detection mechanism are electrically connected to the controller respectively. The invention provides the device capable of automatic replacement of the anti-insect mesh.

Description

technical field [0001] The invention relates to the field of air conditioning equipment. More specifically, the present invention relates to a device capable of automatically replacing insect-proof nets. Background technique [0002] As an important part of the air conditioning system, fresh air is responsible for the normal breathing of indoor personnel and the replacement of indoor air. The "Code for Design of Heating, Ventilation and Air Conditioning in Civil Buildings" GB50736-2012 also has clear requirements for fresh air volume in each area. At the same time For clean areas, the fresh air volume not only bears all the humidity load in the room, ensures that the humidity is controllable, but also an important guarantee for the positive pressure in the room. [0003] The anti-insect net installed at the fresh air inlet can effectively filter insects, moths, fluff and other large objects in the air, prolonging the life of the air filter in the unit. Because it is the fi...

Problems solved by technology

However, the insect-proof nets currently installed are manually dismantled and cleaned, and most of the insect-proof nets are installed in the ceiling, which is inconvenient to install and remove, and it takes time and effort to clean them once; many hospital air-conditioning system maintenance does not consider the cleaning of the insect-proof nets or considers it. There is not enough energy to clean, and the insect-proof net is seriously blocked, which eventually leads to insufficient indoor fresh air volume and affects the normal operation of the entire air-conditioning system
