Pump station structure with drainage device
The invention discloses a pump station structure with a drainage device, and aims to overcome the defect that a submersible sewage pump is easily impacted by water flow to be damaged due to silt deposition in a prefabricated barrel. A submersible sewage pump is mounted at the bottom of the prefabricated barrel, the upper end of the water inlet pipe is connected to a municipal pipe network, the lower end of the water inlet pipe is connected with a flow dividing head, a plurality of water outlet holes facing the bottom of the prefabricated barrel are formed in the flow dividing head, openings of the water outlet holes deviate from the submersible sewage pump, and the drainage pipe is connected with the submersible sewage pump. According to the pump station structure with the drainage device, inlet water of a municipal pipe network is drained to the bottom of the prefabricated barrel and staggered from the submersible sewage pump, the inlet water is prevented from directly scouring the submersible sewage pump, meanwhile, the bottom of the prefabricated barrel can be scoured by utilizing potential energy of the inlet water, and generation of toxic and harmful gas caused by sediment deposition is avoided.
本发明公开了一种带引流装置的泵站结构，旨在解决预制筒体内泥沙淤积，潜污泵容易被水流冲击而造成损伤的不足。该发明包括预制筒体、用于引流的进水管、排水管，预制筒体底部安装潜污泵，进水管上端连接到市政管网，进水管下端连接分流头，分流头上设有若干朝向预制筒体底部设置的出水孔，出水孔的开口朝向偏离潜污泵，排水管与潜污泵连接。这种带引流装置的泵站结构将市政管网进水引流至预制筒体底部且与潜污泵错开，避免进水直接冲刷潜污泵，同时可利用进水势能对预制筒体底部进行冲刷，避免因泥沙淤积造成的有毒有害气体产生。
