Description
Technical Field
The utility model relates to a pumped storage power station technical field, concretely relates to river course filter sand water intaking device.
Background
With the rapid development and technical progress of national economy, the construction of a pumped storage power station serving as an economic and clean large-scale energy storage mode at present is not in the way, and the pumped storage power station not only is a good peak regulation power supply, but also can bear the standby tasks of frequency modulation, phase modulation and rotation of a power grid, improves the power supply quality and the operation safety of the power grid, and brings considerable dynamic benefits to a power system. The pumped storage power station is mostly built in the great mountains, the upper and lower water reservoirs are generally short in straight-line distance and large in height difference, the arrangement of engineering facilities is more complicated than that of a common hydropower station, and the construction period is longer. The water supply in the construction period is an essential prerequisite for the construction of the power station.
The water supply system of the pumped storage power station in the construction period is a complex system project, and has a plurality of construction water consumption points and large quantity. After the system takes water from a water source, water flow enters a collecting tank and a water purifying workshop through a water delivery facility, and then the multi-stage pump station supplies water to each construction point and each construction area respectively. Therefore, the water supply quantity and the water quality of the water source affect the complexity of the arrangement of the water supply facilities and the water supply efficiency. In high and cold mountainous areas such as Xinjiang, inner Mongolia, Qinghai and the like, the construction water supply source of the pumped storage power station is mostly seasonal torrential flood riverways, the riverbeds are wide, the slope rate is high, the torrential flood in summer scours, sand and stone are accumulated, the flow is high, and the main river channel is easy to change; snow melt water is used in spring, autumn and winter, and the flow is small. The water intake mode is generally to build a water-blocking submerged dam along the vertical direction of a main river channel to raise the water level, the upstream surface adopts a grid and a reinforced gabion to filter water, the water flows into a concrete open channel or a diversion gallery through the grid and the reinforced gabion, the open channel or the diversion gallery is connected with a sediment trap, silt carried by the water flow is precipitated in the sediment trap, clean water flow is guided into a suction well through a pipeline, and the water flow is conveyed to a water collecting tank of a water plant through gravity flow or a water pump. In flood season, upstream sand stones are washed down by flood water, rolling stones usually cause deformation or damage of grid mesh steel bars to form large gaps, so that a large amount of sand stones with large particle sizes enter a water diversion gallery and are deposited in a sand sediment well, the deposited sand stones not only cause a sand discharge pump in the sand sediment well to be incapable of working, but also cause deposit blockage of a water diversion pipe, damage of water pump blades, failure of a water meter and the like, and frequent cleaning and maintenance also cause great waste of manpower and material resources. Therefore, the sand filtering device which is simple, convenient, practical, high in rigidity and capable of effectively preventing broken stones and medium coarse sand from entering the diversion gallery is adopted at the head end of the water taking facility to replace a steel bar grating net, so that sediment deposition in the diversion gallery and the sand sediment well is reduced, operation and maintenance costs are reduced, water supply efficiency is improved, and the problem that the existing water pumping and energy storage power station construction water supply engineering sand sediment type mountain torrent river channel water taking needs to be mainly solved is solved.
At present, in the construction of most pumped storage power stations in China, most of water taking buildings of construction water supply systems adopt fixed pump station type, cable car type, bulb type and the like, and the types are generally suitable for taking water from river channels with large water depth, small flow speed, slow slope rate and non-serious silt flushing in flood season. In seasonal mountain torrent watercourses with large gradient, rapid flow velocity and serious scouring and silting, no standard sand-filtering water-taking device or facility with good performance exists, and a hydraulic structure is usually constructed to precipitate and separate silt entering a water diversion system. The method has the advantages of large investment, large occupied area, difficult cleaning of large-particle-size sediments, poor silt separation effect and high later-stage operation and maintenance cost.
