| titleOfInvention | Drainable and backflow-preventive closed-type water collection well cover |
| abstract | The utility model belongs to a draining facility, particularly relates to a drainable and backflow-preventive closed-type water collection well cover and solves the problems that pressure=bearing water exists in a current water collecting well of a hydraulic power plant and the water collecting well is prone to backflow and needs to be manually opened when in use due to the fact that the mouth of the well is sealed by using a pressure-bearing blind plate. The drainable and backflow-preventive closed-type water collection well cover comprises a well cover body, a fixing frame, a one-way check valve and multiple foundation bolts, the foundation bolts are uniformly distributed and vertically mounted around the fixing frame in an inserted manner, the well cover body is arranged at the upper end of the fixing frame, multiple bolt through holes are uniformly distributed around the well cover body, draining through holes are arranged in the middle of the well cover body, a trash rack is arranged on each draining through hole, a diameter-variable pipe is arranged at the lower end of each draining through hole, a big mouth end of each diameter-variable pipe is fixedly connected with the corresponding draining through hole, and a flange plate is arranged on a small mouth end of each pipe-variable pipe and fixedly connected with a water inlet of the one-way check valve through bolts. The drainable and backflow-preventive closed-type water collection well cover is used for draining. |
