Wind-solar combined driven multifunctional natural ventilating device

Abstract

The disclosed equipment includes exhaustion barrel, wind vanes, blower fan, conic increasing gear, switch, solar panel, accumulator, bracket and bearer. The exhaustion barrel is installed on slideway in bearer. Driving fan is installed out of body case at other side of the exhaustion barrel. Being engaged each other, A, B cone gears are installed inside the exhaustion barrel. Through sliding spline, driving fan blades is connected to A cone gear. Through sliding spline, the blower fan is connected to B cone gear. The blower fan is installed under B cone gear, which is installed on slideway with ball bearings on case of motor. Using wind outdoor drives rotation of blower fan so as to generate needed exhaustion. If wind power is not enough, then, accumulator charged by solar power generation drives rotation of blower fan. Features are: novel design, guaranteeing ventilation in door safely and steadily.

Description

technical field [0001] The invention relates to a natural ventilation device, especially a multifunctional natural ventilation device driven by wind energy and solar energy, which is suitable for industrial plants with a large amount of indoor waste heat and places requiring centralized smoke exhaust and ventilation, and belongs to the technical field of ventilation engineering . Background technique [0002] Many industrial plants (such as transformer rooms, etc.) are equipped with a lot of heating equipment, which will generate a lot of waste heat during operation. Exhaust heat. Places such as toilets and kitchens will produce a large amount of exhaust gas and smog, which will seriously endanger human health. In order to achieve the purpose of purifying the air as soon as possible, it is also necessary to use ventilation for ventilation. Although mechanical ventilation can better achieve the effect of smoke exhaust and heat dissipation, it needs to consume a lot of energ...

AI Technical Summary

Problems solved by technology

Although mechanical ventilation can better achieve the effect of smoke exhaust and heat dissipation, it requires a lot of energy, so it is rare to fully utilize mechanical ventilation in actual production.

Natural ventilation is an "economical" ventilation method that does not require any artificial energy costs. However, due to the interference of many external factors, the natural ventilation volume fluctuates greatly, and sometimes it does not even have the effect of exhausting air, which brings great harm to the actual operation. difficulty

[0003] In the existing technology, the application number is 99204624, the authorization number is 20000308, and the name is a utility model patent for a natural ventilation device for the roof. It uses the thermal pressure generated by the temperature difference between indoor and outdoor air for ventilation, but when the thermal pressure is small The wind effect will be very unsatisfactory; the application number is 88204878, the authorization number is 19900131, and the name is a utility model patent for the roof wind extractor. When the fan is too small and cannot rotate, exhaust air cannot be formed and the ventilation effect cannot be achieved.

Most of the existing domestic invention patents on natural ventilation use thermal pressure and wind pressure to generate power, but when the thermal pressure and wind pressure are insufficient, the continuity of natural ventilation is often not guaranteed, and the requirements for eliminating indoor waste heat and smoke cannot be met. , so how to produce efficient and stable natural ventilation and save energy to the greatest extent is the main problem to be solved in the field of natural ventilation technology
