Wind power generation actuating device

Abstract

The invention relates to a wind power generation actuating device which adopts the hydraulic drive mode to replace the traditional gear step-up drive and can realize long-distance mechanical energy transmission of wind power generation so as to realize the purposes of putting a generator on the ground, lightening wind machine high-altitude quality and lowering installation and maintenance difficulty and cost. The wind power generation actuating device of the invention comprises a power part (volume adjustable hydraulic pump), an actuating part (hydraulic motor) and a hydraulic transmission and control part, wherein the hydraulic transmission and control part comprises a volume throttling flow control circuit and ensures the rotation speed of the hydraulic motor. In addition, the hydraulic transmission part also comprises an energy accumulator, a cooling part, an oil filter and a one-way valve, wherein the energy accumulator is used for providing assistant power, and the cooling part is used for cooling hydraulic oil when temperature is too high.

Description

technical field [0001] The invention relates to a transmission mode and device, in particular to an energy transmission mode and transmission device applied to wind power generation. Background technique [0002] Wind power generation uses wind energy to generate electricity, and wind turbines are machines that convert wind energy into electrical energy. The blades of the wind rotor on the wind turbine generate aerodynamic force under the action of the airflow to rotate the wind rotor and convert wind energy into mechanical energy. As far as the horizontal axis wind turbine meter is concerned: the transmission mechanism is responsible for the transmission of energy in wind power generation, changing the very low speed of the wind rotor (usually 27 rpm for a 600-kilowatt fan) into a very high speed of the generator (usually at 1500 rpm). At the same time, it also makes the generator easy to control and realizes stable frequency and voltage output. Its performance directly ...

AI Technical Summary

Problems solved by technology

In extremely low temperature, if the temperature of the gearbox is too low, the lubricating oil will become very thick due to the low temperature, especially if the lubricating parts are splashed, the parts cannot be fully lubricated, which will lead to the lack of lubrication of the gears or bearings and damaged

If only the temperature of the outer engine room is too low, the lubricating oil in the pipeline will also cause the problem of poor flow. When the gearbox oil cannot reach the radiator through the pipeline, the temperature of the gearbox oil will continue to rise until the shutdown

Therefore, traditional wind turbines must install heating devices for the gearbox oil and the interior of the nacelle, which increases the complexity of the system
