Tower horizontal blade hydraulic energy storage wind turbine

Abstract

The invention discloses a tower-type horizontal hydraulic blade energy storage wind-driven generator which comprises a tower drum, tower columns, a wind wheel and a power generating mechanism, wherein the tower columns are fixed on a base; the tower drum is suspended at the upper end of the tower columns in a mode of surrounding the tower columns; a wind catching port and a yawing tail fin are fixedly arranged on the tower drum and are positioned at positions, formed by 180 degrees, at two sides of the tower drum; a center shaft is arranged on an axis of the tower drum; wheel axles are rotationally and fixedly arranged on the center shaft; multiple layers of spiral fan blades are fixedly arranged in the middle of the upper wheel axle; two layers of horizontal fan blades are arranged at the upper part of the upper wheel axle to form the wind wheel; a gearbox is arranged at the lower part of the lower wheel axle; the power generating mechanism comprises the gearbox and a normally-engaged gear type oil pump which is rotationally connected with a driven gear shaft of the gearbox; the normally-engaged gear type oil pump is connected with a generator set oil motor through a pipeline; a power generator is coupled with the generator set oil motor; and a secondary driven gear of the gearbox is coupled with a transfer drive oil pump, and then the transfer drive oil pump communicates with an energy storage oil cylinder group through a pipe. Wind energy is converted into hydraulic energy; the power generator is driven by the oil hydraulic motor, so that the power generating quality is guaranteed; and by using the hydraulic energy storage device, power generation can be realized under the conditions that wind exists or does not exist.

Description

technical field [0001] The invention relates to a tower type horizontal blade hydraulic energy storage wind power generator. Background technique [0002] At present, the common fan in the world is a vertical horizontal axis three-blade fan. The shape of the fan blade adopts a standard streamlined structure; the thrust is obtained by applying the principle of lift to make the wind wheel rotate. This type of fan has a small windward surface of the blade, short action time for the airflow generated by the wind to contact the blade, the blade is heavy, the frame is too high, and the entire set of facilities is installed on the top of the frame; , The control mechanism is complicated and the technology is difficult. The rated wind speed range is narrow when the wind turbine cuts in and out, the sweeping area of ​​the wind rotor is large and the utilization rate of wind energy is low, the wind farm covers a large area, the wind turbines are sparsely distributed, the waste of win...
