Description

Solar exhaust fan

This creation relates to a solar exhaust fan, especially a solar exhaust fan directly driven by the output of a solar panel.

Many factories in China today use simple iron sheets to build buildings to protect them from rain. The advantages are not only fast, but also significantly lower than the average building. The biggest disadvantage of the tin house is that the iron sheet is prone to the problem of rising internal temperature after being exposed to sunlight, especially in the summer tin house, which can reach more than 45 degrees Celsius.

In order to overcome the problem of excessive temperature inside the iron house, a ventilator structure is adopted, which mainly has a plurality of scroll blades connected to the spherical fan group, and a central shaft is assembled in the center of the spherical fan, and the ventilator is installed. It is located at the roof of the factory. When the air blows the ball fan, the spiral fan will rotate around the central axis to generate eddy currents, which will increase the hot air pumping in the plant. However, the ventilator adopts natural wind to rotate it. When there is no wind or the wind is small, the blade cannot rotate, and naturally, the hot air inside the plant cannot be taken out of the room, and the heat removal effect may be required. The exhaust fan is reinforced. However, in addition to the extra power consumption of the exhaust fan, the power supply to the exhaust fan still needs to be pre-measured by means of wire drawing and power distribution. If the plant is not designed with such power configuration in mind, the installation is inconvenient after the installation, and even the original layout of the factory needs to be changed. Therefore, how to improve the lack of prior technology is indeed an issue that the industry wants to overcome.

The purpose of this creation is to solve the problems of power consumption of the exhaust fan in the prior art and the need for re-distribution and poor space utilization.

The power supply module includes a solar panel, and an electronic control unit electrically connected to the solar panel and the engine, the electronic control unit receives the electric energy generated by the solar panel, and is converted into a power output suitable for driving the engine And the operating speed of the engine is positively related to the illuminance of the solar panel.

Further, the connecting portion is provided with a plurality of connecting holes, and the connecting seat is provided with a plurality of connecting holes corresponding to each of the connecting holes, and the solar exhaust fan further comprises a plurality of connecting holes respectively for each of the connecting holes and each of the connecting holes Fasteners.
