The technical field is as follows:

the invention relates to the technical field of mining machinery, in particular to a suspended horizontal roadway wind power generation device with symmetrical double-rotor-wing fan blades.

Background art:

when the mine adopting the underground mining development mode is used for underground air replacement through the constructed ventilation system, airflow with constant wind direction and stable wind speed is formed in an underground roadway, and the airflow can drive a wind driven generator to generate electricity so as to provide power supply for nearby lighting equipment, monitoring equipment and communication equipment. Although the power of the conventional horizontal-axis wind driven generator and the conventional vertical-axis wind driven generator is larger, the size of the windmill is huge, the normal operation of personnel and equipment can be seriously influenced when the windmill is placed in a mine roadway with limited space height and width, and the potential safety hazard of injuring the personnel exists. When the size of the wind turbine generator is reduced to reduce the size of the blades, the capability of the wind turbine to drive the wind turbine is reduced, and the starting wind speed of the wind turbine generator is increased, resulting in a reduction in output.

The invention content is as follows:

the windmills of the conventional horizontal axis wind driven generator and the conventional vertical axis wind driven generator are large in size and cannot be placed in mine roadways with limited space height and width; when the size of the windmill is reduced by reducing the size of the windmill blades, the capability of the windmill driven by wind power is reduced, and the performance of the generator is limited. Therefore, the invention provides the suspended horizontal roadway wind power generation device with the symmetrical double-rotor blades, which occupies a small three-dimensional space, is convenient to install and high in conversion efficiency, and can supply power to lighting equipment, monitoring equipment and communication equipment with low energy consumption nearby.

The invention is realized by the following technical scheme: the horizontal roadway wind power generation device with the symmetrical double-rotor blades comprises a hanging support, a disc type generator, a rotating shaft and two groups of rotor blades, wherein the hanging support is hoisted at the top of an underground roadway, the disc type generator is vertically fixed on the hanging support, two ends of the rotating shaft extend out of the disc type generator, and two ends of the rotating shaft are respectively fixed with one group of rotor blades.

Furthermore, the rotating shaft is parallel to the ground of the underground roadway, and the two groups of cross shaft rotor blades are assembled on the rotating shaft and symmetrically distributed on two sides of the disc type generator; the whole device is horizontal, can be fixed at the top of an underground mine roadway through a suspension bracket, and keeps the rotating shaft vertical to the wind direction in the roadway.

Furthermore, the disc type generator comprises a casing, a rectification voltage stabilizing circuit, a generator stator and a generator rotor, wherein the rectification voltage stabilizing circuit, the generator stator and the generator rotor are arranged in the casing, the generator rotor is fixed on the rotating shaft, and a power supply leading-out cable is connected to the rectification voltage stabilizing circuit. Airflow with constant wind direction and stable wind speed in the underground roadway acts on the two symmetrical rotor blades to drive the generator rotor to rotate and generate electric energy, and the electric energy is output after passing through the rectification and voltage stabilization circuit to supply power for electric equipment.

The invention has the beneficial effects that: according to the suspended horizontal type roadway wind power generation device with the symmetrical double-rotor-wing fan blades, the two groups of cross-shaft rotor-wing fan blades of the device can increase the wind power receiving area of a windmill, the dynamic balance of the device can be ensured in a mode that the fan blades are symmetrically distributed on two sides of the generator, the device can be fixed on the top of a roadway in a suspension mode due to the integral horizontal structure of the device, and the occupation of the effective operation space of the roadway can be reduced.
