Abstract

The invention discloses a double-impeller wind-power smoke exhaust fan which has no consumption of secondary energy sources. The double-impeller wind-power smoke exhaust fan comprises an inner fan, an outer fan and a transmission shaft and is characterized in that each of the inner fan and the outer fan respectively consists of fan blades, a fan blade spring, a junction joint and a positioning ring; the double-impeller wind-power smoke exhaust fan is arranged on a bent automatic windproof and rainproof chimney cap, wherein a smoke exhaust port of the bent automatic windproof and rainproof chimney cap is horizontal and can always keep the same direction with wind; in windy days, angles of the fan blades of the outer fan deflect to generate rotating power under the action of wind power so as to drive the inner fan to rotate by the transmission shaft, and therefore the angles of the fan blades of the inner fan deflect to generate power of wind blowing outwards; and in windless days, the fan blades of the outer fan and the inner fan reset and stop rotating under the action of the respective spring. The double-impeller wind-power smoke exhaust fan disclosed by the invention has the advantages of providing convenience for smoke exhaust by using primary wind energy, saving energy sources and protecting the environment.

Description

Technical field: [0001] The invention relates to an exhaust fan, in particular to a double impeller wind-powered smoke exhaust fan. Background technique: [0002] There are many types of smoke exhaust fans, all of which need to be driven by a motor, which consumes secondary energy and pays for power costs. Invention content: [0003] The purpose of the present invention is to provide a double-impeller wind-powered smoke exhaust fan that does not need to consume secondary energy, and converts the natural wind that affects smoke exhaust into power to assist smoke exhaust, turning disadvantages into benefits and benefiting the people. [0004] The present invention realizes through following technical scheme: [0005] A double-impeller wind exhaust fan, including an inner fan, an outer fan and a transmission shaft, characterized in that: the inner fan and the outer fan are respectively composed of fan blades, fan blade springs, coupling joints and positioning rings, and the ...
