Abstract
The utility model discloses an unpowered roof fan, which comprises a base, a wind tube, a blade lower fixing plate, fan blades, a center shaft, a fan blade upper fixing plate, an upper bearing plate and a wind cap, wherein the upper ends of the fan blades are respectively fixed on the fan blade upper fixing plate, the lower ends of the fan blades are respectively fixed on the blade lower fixing plate, all of the fan blades form a worm wheel shape, the upper end of the center shaft passes through the fan blade upper fixing plate to be inserted into an upper bearing for being fixedly connected with the upper bearing plate, the lower end of the center shaft passes through the blade lower fixing plate to be inserted into a lower bearing for being fixedly connected with a lower bearing support frame, the lower bearing support frame is fixedly connected onto the wind tube, the base and the wind tube are fixedly connected in a sealed way, the wind tube and the blade lower fixing plate are fixedly connected in a sealed way through rivets and sealing glue, the upper bearing plate is welded in the wind cap, and the wind cap and the fan blade upper fixing plate are fixedly connected in a sealed way through rivets and sealing glue. The unpowered roof fan does not need electric power driving, energy sources are saved, simultaneously, the noise generated when a motor works is avoided, and a better environment protection effect is obtained.
Description
Technical field
The utility model relates to a kind of Fan Equipment, is specifically related to a kind of unpowered roof ventilator.
Background technique
Roof ventilator generally is installed on the roof of steel structure or concrete structure building, is used for from indoor discharge gas effect with fresh air in the holding chamber.The prior roofs blower fan generally is made up of air duct, blast cap, blower fan, motor, electrical machinery cover, bird proof net etc., needs motor driving in running.This electronic roof ventilator need consume bigger electric energy, if in the open air or do not have under the situation of power, electronic roof ventilator just can't proper functioning.Therefore, need a kind of unpowered roof ventilator, utilize wind energy to reach the exchange of indoor air, holding chamber is interior with fresh air.
Summary of the invention
The utility model provides a kind of unpowered roof ventilator at the deficiencies in the prior art, need not motor driving, utilizes wind energy to drive blower fan work, carries out the exchange of indoor and outdoor air.
In order to reach above-mentioned day, the utility model adopts following technological scheme: a kind of unpowered roof ventilator, comprise base, air duct, fan blade bottom plate, fan blade, central shaft, fan blade upper mounted plate, upper bearing (metal) plate, blast cap, the upper end of fan blade is separately fixed on the fan blade upper mounted plate, the lower end of fan blade is separately fixed on the fan blade bottom plate, and all fan blades are formed turbine-like; Central shaft upper end is passed the fan blade upper mounted plate and is inserted in the upper bearing (metal) and fixedly connected with the upper bearing (metal) plate, and the central shaft lower end is passed the fan blade bottom plate and inserted in the lower bearing and fixedly connected with lower bracket, and lower bracket is fixedly connected on the air duct; Base and air duct are sealedly and fixedly connected, and air duct and fan blade bottom plate are sealedly and fixedly connected by rivet and sealer; The upper bearing (metal) plate is welded in the blast cap, and blast cap and fan blade upper mounted plate are sealedly and fixedly connected by rivet and sealer.
The beneficial effects of the utility model are: use the unpowered roof ventilator of the utility model, utilize the indoor air lift and the wind-force on roof, make the work of the utility model blower fan, not only can solve the problem of indoor exhausting ventilation, improve indoor air environment, and need not electric drive, can more be applicable to the field or lack room ventilation ventilation work under the electric power situation, energy saving, the noise of having avoided machine operation to produce simultaneously, environmental protection more.
