Energy-saving mechanical hydraulic energy storage equipment and method

Abstract

The invention discloses energy-saving mechanical hydraulic energy storage equipment and method. The energy-saving mechanical hydraulic energy storage equipment and method comprise an energy storage part, an oil valve system, a counterweight water tank system and a pulley part. The energy storage part is an energy storage device and is used for storing high-pressure working hydraulic oil sprayed out of the oil valve system. The oil valve system and the energy storage part constitute an oil liquid circulating pipeline system used for conveying hydraulic oil in the energy storage equipment. The counterweight water tank system comprises a counterweight part and a water ball valve pipeline part. The counterweight part comprises a water storage tank, a traction steel wire rope and a counterweight device. The counterweight device and the water storage tank form a motion system of the energy storage equipment through the traction steel wire rope and the pulley part. According to the energy-saving mechanical hydraulic energy storage equipment and method, because the potential energy of water resources of the energy-saving mechanical hydraulic energy storage equipment is mainly converted into hydraulic potential energy which can be conveniently used, energy conversion links are reduced, the electric energy consumption of a motor is reduced, the control is simple, the cost investment is reduced, the maintenance is convenient, the operation cost is low, the potential energy levels are different and can be conveniently switched, and an energy station of a gas system and an oil system can be built.

Description

technical field [0001] The invention relates to a hydraulic control device and a hydraulic control energy storage method, in particular to an energy-saving mechanical hydraulic energy storage device and method. Background technique [0002] At present, it is common for hydropower stations and water conservancy facilities to use hydraulic equipment for electromechanical equipment. Conventional hydraulic systems use motors and oil pumps for energy storage. The operation of oil pumps consumes electric energy and is characterized by high operation and maintenance costs. At present, hydraulic energy is stored in the black start scheme of the security system, and the energy stored in traditional equipment is limited; if the backup energy of the energy storage equipment is insufficient or accidentally lost, the system is required to be put into operation urgently, and the limitations of traditional equipment to solve the starting system are more prominent.
