Abstract

The invention discloses an unpowered draught fan and a manufacturing method and application thereof. The unpowered draught fan comprises a base, an air duct, fan blades, a top cover, a waterproof mechanism, a driving mechanism and a balance mechanism. The fan blades are evenly arranged between the top cover and the air duct, a supporting mechanism is arranged on the top face of the base, the waterproof mechanism comprises a waterproof cylinder, the waterproof cylinder is located on the inner side of the air duct, and a first positioning support is horizontally arranged in the air duct; a rotary shaft is perpendicularly connected to the first positioning support, the rotary shaft is rotatably connected to the center of the first positioning support, and the driving mechanism is fixedly connected to the bottom end of the rotary shaft; and the balance mechanism is connected to the rotary shaft in a sleeving mode and located between the top cover and the air duct, and the top end of the rotary shaft penetrates through the top cover and is connected to the center of the supporting mechanism. The manufacturing method of the unpowered draught fan comprises the steps of machining of the base, machining and installation of the air duct and the waterproof cylinder, installation of the supporting mechanism, installation of the balance mechanism, installation of the fan blades, installation of the driving mechanism and testing of the unpowered draught fan. The invention further discloses application of the unpowered draught fan in greenhouse planting.

Description

technical field [0001] The invention relates to a non-powered fan, its manufacturing method and application. Background technique [0002] The unpowered fan uses the natural wind speed of nature to drive the turbine of the fan to rotate, and uses the principle of indoor and outdoor air convection to accelerate and transform any parallel air flow into a vertical air flow from bottom to top to improve indoor ventilation. A device for air effects. The blower does not need electricity, has no noise, and can run for a long time. According to the natural law of air and the principle of air flow, it is rationally installed on the top of the roof, which can quickly discharge indoor hot air and dirty air and improve the indoor environment. [0003] The non-powered fan in the prior art has no obvious effect on the air flow in the house, and the use effect in greenhouse planting is even worse, and it cannot well perform the functions of heat dissipation and exhaust.
