Hydraulic wind power generation device

Abstract

The invention provides a hydraulic wind power generation device. The wind power generation device is provided with a control module and an energy storage device capable of storing energy through a high pressure working medium; two or more energy storage pumps are driven by fan blades of the wind generation device through a gearbox; when the working medium is oil, the energy storage pumps are hydraulic pumps, and when the hydraulic pumps are driven, the oil in an oil tank is pumped into the energy storage device to form high pressure oil for energy storage; the hydraulic pumps comprises a largedischarge capacity hydraulic pump and a small discharge capacity hydraulic pump; clutchs capable of enabling the hydraulic pumps to be disconnected with the fan blades are connected to all the hydraulic pumps; and the control module controls the number and the discharge capacity of the hydraulic pumps driven by the fan blades through the clutches according to the current wind speed, so that the wind speed cut-in and cut-out range of a fan of the wind power generation device is enlarged. According to the wind power generation device, the wind speed cut-out and cut-in range can be enlarged, theinstallation is convenient, and the power output is stable.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a hydraulic wind power generation device. Background technique [0002] Usually the cut-out wind speed of a wind power generation device is 25m / s, and the cut-in wind speed is generally about 3m / s. Therefore, it is often seen that there is wind but the fan stops at the wind power plant, because the wind speed is too high to protect the fan. Big waste of energy. [0003] At present, the height of large-scale wind turbines can reach hundreds of meters, and the weight of generators can reach hundreds of tons, which is very inconvenient to install. Contents of the invention [0004] The invention proposes a hydraulic wind power generating device, which can expand the wind speed cut-out and cut-in range of the wind power generating device, and is easy to install and has stable power output. [0005] The present invention adopts the following technical solutions. [...
