[0002] Traditional outdoor oil cylinder valve groups of hydraulic hoists are not designed with sufficient protection measures, resulting in a series of problems when used outdoors. Existing outdoor oil cylinder valve groups of hydraulic hoists usually consist of valve blocks, solenoid valves, and pressure sensors, and these components are directly exposed to the outdoor environment. Due to the lack of a protective cover, when the valve group is exposed to harsh environments such as wind, rain, direct sunlight, and dust pollution for a long time, the valve block is prone to rust, and the failure rates of the solenoid valve and the pressure sensor also increase accordingly. These problems directly affect the normal operation of the flood discharge gate and may further threaten the safety of the dam. Summary of the Invention
