An underground energy storage device arranged in an underground continuous wall

Abstract

An underground energy storage device arranged in an underground diaphragm wall comprises an air compressor, gas storage steel pipe tail sections, main gas storage steel pipes, continuous gas storage steel pipe sections and oblique gas storage steel pipe sections, wherein the two ends of each continuous gas storage steel pipe section are connected with the corresponding oblique gas storage steel pipe section and the corresponding gas storage steel pipe tail section respectively to form an independent gas storage steel pipe unit; one independent gas storage steel pipe unit is pre-buried in each of the two sides of each underground diaphragm wall unit; the two oblique gas storage steel pipe sections inside each underground diaphragm wall unit are connected with the first main gas storage steel pipe; the two gas storage steel pipe tail sections inside each underground diaphragm wall unit are connected with the second main gas storage steel pipe; the air compressor is arranged at one end of the first main gas storage steel pipe; one end of the second main gas storage steel pipe is an air outlet pipeline. By the adoption of the structure, the space inside the underground diaphragm wall is fully utilized, a compressed air energy storage system is formed without affecting the stability of the underground diaphragm wall, and the functions of cool supply, heat supply, pressure potential energy power generation and deformation detection of the underground diaphragm wall are achieved.

Description

technical field [0001] The invention relates to the field of underground energy storage equipment, in particular to an underground energy storage device arranged in an underground continuous wall. Background technique [0002] As an effective demand-oriented management method at the present stage, peak-valley time-of-use electricity pricing has been widely adopted in countries all over the world. For example, the peak-valley differential electricity price for residents in Shanghai, my country is specifically: from 6:00 a.m. to 22:00 p.m., the peak-hour electricity price is implemented, which is 0.617 yuan / kWh. From 22:00 in the evening to 6:00 in the morning of the next day, the electricity price in valley hours is 0.307 yuan / kWh, and the price difference is more than doubled. For a building, if the energy can be stored during the off-peak electricity price and released during the peak electricity price, as an effective supplement to the normal power supply, it will greatly...
