Pressure regulating chamber for realizing surge self-suppression by utilizing gravitational potential energy and pressure regulating method
The invention provides a pressure regulating chamber and a pressure regulating method for realizing surge self-suppression by using gravitational potential energy. Comprising a vertical shaft, a gravity assembly is inserted into the upper end of the vertical shaft, the gravity assembly comprises a water bearing cylinder of a hollow structure, the bottom of the gravity assembly extends into the vertical shaft, and the top of the gravity assembly is flush with the top of the vertical shaft; a gap is formed between the outer wall of the water bearing cylinder and the inner wall of the vertical shaft; the cross sectional area of the gap is smaller than that of the water bearing cylinder, and water blocking plates are arranged in the gap and the water bearing cylinder; a first one-way valve and a second one-way valve are sequentially arranged on the side wall of the water containing barrel from the bottom to the top of the water containing barrel. The advantages of an impedance type surge chamber and a differential type surge chamber are integrated, the self weight of the gravity assembly and water energy conversion are fully utilized to achieve surge self-suppression, the fluctuation amplitude of the internal water level is relieved, water gushing attenuation is accelerated, the situation that water breaks through the chamber is reduced or avoided, the construction cost is reduced, and compared with a conventional surge chamber structure, the surge chamber has obvious advantages.
本发明提出一种利用重力势能实现涌浪自抑的调压室以及调压方法；包括：竖井，所述竖井上端插接有重力组件，所述重力组件包括空心结构的承水筒，其底部伸入所述竖井内且其顶部与所述竖井的顶部齐平；所述承水筒的外壁与所述竖井的内壁之间有间隙；所述间隙的横截面积小于所述承水筒的横截面积，并在所述间隙和所述承水筒内设置有阻水板件；由所述承水筒的底部向其顶部在所述承水筒的侧壁上依次设置第一单向阀和第二单向阀。本申请综合了阻抗式调压室差动式调压室的优点，又充分利用重力组件的自重和水体能量转换实现涌浪自抑，缓解内部水位波动幅度、加快涌水衰减，降低或避免水击穿室、减少工程造价，对比常规调压室结构，具备明显优势。
