Problems solved by technology

However, due to the use of nylon rotating shaft and nylon bushing for sliding rotation, and the equipment is operated in the steam turbine room of a thermal power plant with a lot of coal ash, after a period of operation, the sliding and rotating part will fail to rotate due to the entry of coal ash , and then unable to rotate due to blockage, unable to achieve the function of rainproof and adjustment; the structure design of the adjustable rainproof valve plate is flat and simple, and can only play a simple closing function, lacking the function of secondary rainproof

Abstract

An electric stormproof louvre belongs to the manufacture technical field of ventilation facilities and mainly comprises an outer frame consisting of an upper and lower frame (1) and a side frame (2), a fixing stormproof blade (3) arranged at the inner part of the outer frame, an adjustable stormproof valve (4) provided with a rotating shaft (10), an electric executing mechanism (7) arranged at the bottom of the outer frame, a connecting bar drive device (6) arranged at the side of the side frame (2) and respectively connected with the electric executing mechanism (7) and one end of the rotating shaft (10), a full-closed type stainless steel ball bearing (5) arranged between the rotating shaft (10) and the side frame (2), a stainless steel protecting net (8) arranged outside the fixing stormproof blade (3), and the like. Two ends of the adjustable stormproof valve (4) are respectively provided with a 90-degree round hook structure. The invention has reasonable integral structure design and can effectively improve the rainproof property.

Description

technical field [0001] The invention relates to an electric rainproof louver, which belongs to the technical field of ventilation equipment manufacture. Background technique [0002] Electric rainproof louvers are rainproof ventilation facilities used in large thermal power plants, nuclear power plants and industrial plants. The existing electric rainproof louvers are mainly composed of fixed rainproof blades, adjustable rainproof valves, upper and lower frames, and drainage grooves. It is composed of side frame, sliding nylon bushing, nylon rotating shaft, electric actuator and so on. However, due to the use of nylon rotating shaft and nylon bushing for sliding rotation, and the equipment is operated in the steam turbine room of a thermal power plant with a lot of coal ash, after a period of operation, the sliding and rotating part will fail to rotate due to the entry of coal ash , and then cannot rotate due to blocking, and cannot achieve the effect of rainproof and adjus...
