Title:
NEGATIVE PRESSURE ENERGY STORAGE SYSTEM BASED ON PHOTOELECTRICITY AND WIND POWER
Document Type and Number:
WIPO Patent Application WO/2023/151361
Kind Code:
A1
Abstract:
A negative pressure energy storage system based on photoelectricity and wind power, comprising a negative pressure tank (1). One side of the negative pressure tank (1) is connected to a pumping brake valve (4); one side of the pumping brake valve (4) is connected to a pumping pipeline (3); one end of the pumping pipeline (3) is connected to a vacuum pump (2); the other side of the negative pressure tank (1) is connected to an air suction pipeline (5); a drive mechanism (6) is mounted in the middle of the air suction pipeline (5); an air suction brake valve (7) is arranged on one side of the drive mechanism (6); a power generator set (10) is arranged on the lower part of the drive mechanism (6); a driven belt pulley (1001) is arranged on one side of the power generator set (10); a driving belt pulley (610) is connected to the driven belt pulley (1001) by means of a transmission belt (614). According to the system, the vacuum pump (2) is used to enable the negative pressure tank (1) to generate negative pressure, and then the capacity and process that a negative pressure tank body can automatically suction air to balance the pressure difference between the interior and the exterior of the tank body are used in cooperation with a brake valve capable of controlling opening and closing and air volume. Blades (603) are blown to rotate in the air suctioning process to drive the power generator set (10) to generate power, the storage function of clean energy is achieved by using air, the air participates in adjustment of a load curve and peak load shifting of power grid, and the comprehensive benefits of wind power generation and solar power generation equipment are improved.
