Small wind power generation device based on tunnel ventilation

Abstract

The invention discloses a small wind power generation device based on tunnel ventilation. The small wind power generation device comprises a vertical support, a wind wheel, a wind speed detection unit, a generator for converting the kinetic energy of the wind wheel into electric energy and an electronic circuit board installed on the vertical support. The top portion of the vertical support is provided with a wheel axle position limiting element which is used for performing position limiting on the wheel axle of the wind wheel and can be rotated up and down. The vertical support is provided with an electric drive pusher for driving the up and down rotation of the wheel axle position limiting element. The electronic circuit board is provided with a controller, a charger, a storage battery connected with the charger, a electric quantity detection unit, a current detection unit, and a parameter setting unit and a display unit which are connected with the controller separately. The controller is used to control the electric drive pusher according to data detected by the wind speed detection unit. According to the invention, advantages of reasonable design, convenient installation and layout, convenient utilization and operation and good utilization effect can be realized, the wind energy in tunnel ventilation can be effectively utilized, and the generated electric energy can be stored synchronously.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a small wind power generating device based on tunnel ventilation. Background technique [0002] Wind is a new energy source with great potential. From the perspective of economic rationality, when the wind speed is greater than 4m / s, it is suitable for power generation. According to the measurement, a 55 kilowatt wind turbine, when the wind speed is 6m / s, the output power is 16 kilowatts; when the wind speed is 5m / s, the output power is 9.5 kilowatts, so the stronger the wind, the greater the economic benefits . [0003] The function of ventilation in tunnel construction is to deliver enough fresh air from the outside of the tunnel to the inside of the tunnel, and discharge the gun smoke and harmful gases produced by blasting and transportation in the tunnel, so as to finally ensure the needs of the workers and machinery in the tunnel for fresh air, so that the inside of the tun...

AI Technical Summary

Problems solved by technology

To sum up, there is a lack of a small-scale wind power generation device with simple structure, convenient layout and installation, good use effect and high economic benefits, which can effectively use the wind energy in the tunnel ventilation, and can adjust the wind speed of the current period according to the wind speed at the location. Whether to generate electricity in the state is controlled, and the generated energy can be stored synchronously
