Pneumatic shield gate system powered by wind-solar hybrid power generation

Abstract

The invention discloses a pneumatic shield gate system for wind and solar complementary power generation, which includes a gate unit, a pneumatic power unit, and a power generation and power supply unit; It consists of a pneumatic control valve group for opening and closing a pneumatic shield gate, and a PLC controller that controls the action of the pneumatic control valve group; the pneumatic power unit is composed of at least two parallel air storage tanks and at least two parallel air compressors. , the air outlet of the air compressor is connected to the air inlet of the air storage tank and the pneumatic control valve group through the air outlet check valve through the combination of the front filter, the air dryer and the rear filter; the power generation unit includes wind power generation machines, solar panels, wind and solar hybrid controllers, and inverters. The advantage of the invention is that it is designed for the construction of barrage and sluice projects in remote and remote mountainous areas without power supply, and uses the characteristics of strong complementarity between wind energy and solar energy in terms of time and area to improve the stability of system operation.

Description

technical field [0001] The invention relates to a pneumatic shield gate, in particular to a pneumatic shield gate system powered by wind-solar complementary power generation. Background technique [0002] Water conservancy is closely related to the national economy and the people's livelihood, and its strategic position is becoming increasingly important. In particular, the current focus is on the comprehensive improvement of rural rivers, the development of rural hydropower, and the construction of small and medium-sized water conservancy facilities. However, because power grids in some remote areas and mountainous areas have not yet been erected, it is necessary to solve the power problem when the gate is opened and closed during the construction of the barrage sluice project. floodgates to ensure the safety of people's lives and property. The existence of the above-mentioned problems has been a subject of research by those skilled in the art, but there are no related re...
