Efficient and energy-saving flood drainage pump station for water conservancy project
The invention relates to the field of water conservancy project equipment, in particular to an efficient and energy-saving flood drainage pump station for a water conservancy project. Water fluctuation energy is converted through an energy capturing mechanism, a pressurizing cylinder is driven to pressurize a water pumping pipe, a compensation effect on a pressure difference generated when a waterdraining pump lifts water is achieved, and electric power input is not needed, so that the energy consumption is reduced while the drainage efficiency is improved, and the purpose of saving energy isachieved; the energy capturing mechanism can block large stones, so that the protection capacity for a dam, a water suction pipe and a sand filtering cylinder is improved; the sand filtering cylinderis used for filtering silt in the water entering the water pumping pipe, the lift capacity of the water draining pump is improved, the energy consumption is reduced, the energy-saving effect is further achieved, and meanwhile, the service life of the water draining pump is prolonged; and the pressurizing cylinder can also play a role in back flushing on the sand filtering cylinder, the efficientfiltering effect of the sand filtering cylinder is kept, the energy capturing mechanism can further drive a sand discharging mechanism to clean the silt and the stones at the bottom of the dam, time and labor are saved, and normal work of the whole flood drainage pump station is guaranteed.
本发明涉及水利工程设备领域，具体为一种水利工程用高效节能的排涝泵站，通过捕能机构转化水体波动能量并驱动增压筒对抽水管进行增压，对排水泵提升水液产生的压力差起到补偿作用，而且无需电力输入，从而在提升排水效率的同时降低能耗，达到节能的目的，并且捕能机构能够对较大的石块起到阻挡作用，提高对堤坝、吸水管和滤沙筒的保护能力，并利用滤沙筒对进入抽水管内部的水液过滤泥沙，提高排水泵的扬程能力，降低能耗，进一步起到节能的作用，同时提高排水泵的使用寿命，并且增压筒还能够对滤沙筒起到反向冲洗的作用，保持滤沙筒高效的过滤效果，捕能机构还能够驱动排沙机构对坝底的泥沙石块进行清理，省时省力，确保整个排涝泵站正常工作。
