Embodiment 1

[0020] Such as figure 1 with 2 As shown, the civil air defense engineering ventilation equipment includes a base 1, a fan 2, a drive shaft 3, a gearbox 4, a DC motor 5, a DC motor controller 6, a battery and four foot-operated driving devices 7. The ventilation equipment of the civil air defense project of the present invention has high working efficiency, and the equipment adopts three driving modes: alternating current drive, manpower plus direct current auxiliary drive and pure manpower drive, and has the advantage of diversification of drive modes.

[0021] The base 1 is a platform welded by angle irons, and the base 1 is used as a platform to carry equipment such as a fan 2 and a foot-operated driving device 7, which is convenient for the use and transportation of the ventilation equipment for civil air defense projects. The fan 2 is made up of a blower 21 and an AC motor 22 that drives the blower 21 to rotate. The AC motor 22 is a three-phase AC motor. One end of the ro...

Abstract

The invention relates to ventilating equipment for civil air defense engineering. The equipment comprises a base, a fan, a transmission shaft, a transmission, a direct current motor, a direct current motor controller, a storage battery and at least two pedal driving devices, wherein the transmission shaft is rotatably mounted on the base through a fixed seat; the transmission is fixedly mounted on the base and is located between the transmission shaft and the fan; a power output shaft of the transmission is detachably connected to the rotary shaft of a fan through an alternating overrun clutch; a power input shaft of the transmission is detachably connected to one end of the transmission shaft; a direct current overrun clutch is fixedly mounted on the transmission shaft; the power input shaft of the transmission is detachably connected to one end of the transmission shaft; a direct current overrun clutch is fixedly mounted on the transmission shaft; a first driven chain wheel is mounted on an outer wheel of the direct current overrun clutch; and each of the pedal driving devices comprises a pedal frame, a crankshaft, a bicycle flywheel and a bicycle wheel disc. The ventilating equipment for civil air defense engineering provided by the invention has the advantages of being high in work efficiency and diversified in driving modes: three driving modes: alternating current driving, manpower and direct current auxiliary driving and pure manpower driving.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering equipment, in particular to a ventilation equipment for civil air defense engineering. Background technique [0002] As we all know, civil air defense projects are special underground buildings with protection requirements. Civil air defense projects include exterior walls, buffer walls, explosion-proof doors, closed walls, protective partition walls, etc., and are mainly used for civil air defense temporary bunkers, wartime air defense command centers, Communication center, hideout, etc. Because there will be a large number of people gathered in the civil air defense project during the war, and the average air breathing volume of a person is about 30 cubic meters per hour, this puts a test on the air supply equipment of the civil air defense project, but the current air supply equipment is still used in the 1970s Products, the main problems of existing gas supply equipment ...
