Wind-driven water lifting device

Abstract

The invention discloses a wind-driven water lifting device. The wind-driven water lifting device comprises a fan, a torque adjuster and a sliding vane pump; an output shaft of the fan is in transmission connection with a rotor shaft of the sliding vane pump; an axle head of the rotor shaft of the sliding vane pump is provided with the torque adjuster; and the bottom end of a toque adjusting pull rope of the torque adjuster is fixedly connected with a pull rod of the sliding vane pump. The wind-driven water lifting device disclosed by the invention has the advantages that relative positions ofa swimming ring and a circular rotor which are positioned inside the sliding vane pump can be adjusted by virtue of wind power so that the volume inside the sliding vane pump can be automatically adjusted according to the strength of the wind power, the discharge capacity of the sliding vane pump is automatically adjusted according to the strength of the wind power, and a water pump can realize stable output; the sliding vane pump can be matched with the fan within a range from a point when the fan is started to a point when the fan reaches a rated wind speed according to a torque adjustment system so as to form an optimal matching wind speed range, and the sliding vane pump can realize running under a high-efficiency work condition within the range. The wind-driven water lifting unit is high in work efficiency, small in start torque and stable in work.

Technical field: [0001] The invention relates to a device for lifting water by using wind energy, in particular to a device for lifting water by wind power. Background technique: [0002] The matching of the wind turbine and the water pump in the wind water pump is a very complicated problem, and it has been difficult to solve for a long time. Due to the large difference between the output characteristics of the water pump and the torque characteristics of the wind turbine rotor in the existing wind-driven water pumps, the best match between the efficiency of the wind rotor and the water pump can only be a point, and cannot match in a range, that is, only the output of the wind turbine The water pump can only be driven to work when the rotation speed meets the input speed of the water pump. When the wind is weak or light, the output shaft of the wind turbine needs to be locked to avoid loss of the water pump; when the wind is too strong, the output shaft of the wind turbine ...

[0002] The matching of the wind turbine and the water pump in the wind water pump is a very complicated problem, and it has been difficult to solve for a long time

Due to the large difference between the output characteristics of the water pump and the torque characteristics of the wind turbine rotor in the existing wind-driven water pumps, the best match between the efficiency of the wind rotor and the water pump can only be a point, and cannot match in a range, that is, only the output of the wind turbine The water pump can only be driven to work when the rotation speed meets the input speed of the water pump. When the wind is weak or light, the output shaft of the wind turbine needs to be locked to avoid loss of the water pump; when the wind is too strong, the output shaft of the wind turbine must be locked. Limit the speed to prevent damage to the water pump; and in the design, the rated wind speed is designed according to the actual conditions, and the water lifting capacity matched with the wind speed at this time reaches the maximum working efficiency of the pump, which is the best matching wind speed. The specific situation (increase or decrease of the average wind speed) is adjusted accordingly, which makes it difficult to determine the design wind speed (ie, the best matching wind speed) of the wind power water pumping unit, and the unit has low working efficiency, poor economy, and poor adaptability
