Problems solved by technology
The depth of the rainwater forebay and the pump room is generally below 11m underground, and the height above the ground of the pump room is more than 9m. The civil construction and equipment investment of the pump room is huge, and the motor must be removed before the pump body can be hoisted out of the ground when repairing the rainwater pump. Installation, Maintenance is extremely inconvenient and work efficiency is low

The invention discloses a rainwater drainage system in a factory. The rainwater drainage system comprises a rainwater pump body, a rainwater pump motor and a rainwater tank, wherein the rainwater pump body, the rainwater pump motor and the rainwater tank are connected. The rainwater pump body is connected with a water outlet pipe through a switching valve, the water outlet pipe is connected with a water drainage pipeline, the switching valve is supported by a lower supporting face through a support, and the water outlet pipe is higher than a water outlet of the rainwater pump body and the water drainage pipeline. The rainwater tank is connected with an outer rainwater inflowing pipeline, the rainwater pump body is connected with the water outlet end of a water sucking pipe, and the water inlet end of the water sucking pipe is arranged on the lower portion of the rainwater tank and connected with a fixing support. The fixing support is supported by the lower ground surface, and a lead wire net is arranged on the periphery of the fixing support. The rainwater tank at the water inlet side is internally provided with a separation grid for separating large impurities such as suspended matter out. The rainwater drainage system in the factory is small in occupied area, capable of saving pump house civil engineering investment, convenient to install, maintain and overhaul, capable of reducing rainwater pump house civil engineering and equipment investment and capable of lowering the maintenance difficulty level of a rainwater pump.
Description
technical field [0001] The invention relates to the technical field of drainage equipment, in particular to a rainwater drainage system in factory areas, which is applied to rainwater drainage in thermal power plants, chemical plants and other factory areas. Background technique [0002] In the prior art, thermal power plants, chemical plants and other factories occupy more and more land. In order to meet the drainage requirements, the diameter and buried depth of rainwater pipes in the factory area are getting larger and larger, and usually the rainwater pump room needs to be installed in the factory area. In the prior art, vertical mixed-flow pumps are usually used for rainwater pumps. Because the impeller of the vertical mixed-flow pump has a wide water inlet channel, it can effectively prevent clogging, and is suitable for water sources such as rainwater with a lot of impurities in the water. The depth of the rainwater forebay and the pump room is generally below 11m und...
