Abstract
The utility model provides a combined impact energy dissipation box structure, which comprises an energy dissipation box body, a first energy dissipation structure, a second energy dissipation structure, a grid cover plate, and a water inlet and a water outlet of the energy dissipation box; the energy dissipation box body is a semi-closed box body, the upper part of the box body is of a cavity structure, and the lower part of the box body is divided into two communicated inner cavity structures by the first energy dissipation structure and the second energy dissipation structure. Through combined energy dissipation, the outflow condition is improved, the outlet flow speed is reduced, and the scouring effect of water flow on the downstream is further reduced. When the low-speed water flow enters the energy dissipation box, the first energy dissipation structure can meet the energy dissipation requirement. When high-speed water flow enters the energy dissipation box, the water flow overflows the partition plate, and the first energy dissipation structure and the second energy dissipation structure are combined to fully dissipate energy. Compared with the traditional impact energy dissipation box, the structure has the remarkable characteristics of high space utilization rate, simplicity and convenience in construction and high energy dissipation efficiency.
