The invention provides a self-cleaning type workshop roof power-free fan which comprises an air hose, a blade ring, a supporting shaft, a top cover, an air ball, a water receiving bag, a first detection mechanism, a second detection mechanism, a first alarm mechanism, a second alarm mechanism and a control mechanism. An annular water tank is installed at the position, between the top cover and a fan support, on the supporting shaft, spray heads are distributed on the outer wall of the annular water tank, inlets of the multiple spray heads communicate with an inner cavity of the annular water tank, the multiple spray heads are all controlled by a control mechanism to work for spraying water to the periphery for cleaning fan blades, a water inlet channel communicating with the inner cavity of the annular water tank is arranged in the supporting shaft, and a water inlet of the water inlet channel communicates with an external water storage tank through a water inlet pipe. By means of mutual cooperation of the control mechanism, the first detection mechanism, the second detection mechanism, the first alarm mechanism, the second alarm mechanism and the multiple spray heads, the self-cleaning function of the power-free fan is achieved, the ventilation effect of the power-free fan is improved, and sewage produced through cleaning is collected by the water receiving bag to be processed.
Description
technical field [0001] The invention relates to the technical field of non-powered fans, in particular to a self-cleaning non-powered fan on the roof of a factory building. Background technique [0002] The non-powered ventilator is a commonly used type in the roof ventilator series, which is mainly used in the top floor of the community, hospitals, restaurants, gymnasiums, large factories and other occasions that require roof ventilation. The unpowered fan uses the natural wind speed to drive the turbine of the fan to rotate, and uses the principle of indoor and outdoor air convection to capture the wind force on the windward side through the blades on the turbine blade shell, push the blades, and make the turbine blade shell rotate. At the same time, centrifugal force is generated due to the rotation. , the air under the turbine is induced to be discharged between the blades on the leeward side. After the air is discharged, a low-pressure area is formed under the turbine. ...
