Urban underground pipe network water taking device

Abstract

The invention discloses an urban underground pipe network water taking device which comprises a top exhaust cover, a compression bin, a water suction bottom cover and a plurality of connecting operation rods and is characterized in that the upper end and the lower end of the compression bin are connected with the top exhaust cover and the water suction bottom cover respectively, external threads are arranged at the lower end of each connecting operation rod, and internal threads are arranged at the upper end of each connecting operation rod; the lower end of the first connecting operation rod is connected with the top exhaust cover, the lower end of the second connecting operation rod is connected with the upper end of the first connecting operation rod, and the last connecting operation rod is connected in sequence. The device mainly aims at the working environment that water flow of a rainwater pipe network in sunny days is small, sampling is difficult through a conventional rope hanging container method, and sampling cannot be conducted through an existing water taking tool. When the water taking device is used, a worker stands above an inspection well and uses the working rod to operate the water taking device, the connecting operation rod is pushed and pressed up and down to drive the compression bin, and a to-be-detected water body in a rainwater pipe is sucked into the compression bin by utilizing an internal and external pressure difference.

Description

technical field [0001] The invention belongs to the field of water construction, and relates to a sampling inspection device for an urban underground pipe network, in particular to a water intake device for an urban underground pipe network. Background technique [0002] At present, my country's cities have been developing for decades. With the continuous expansion and construction of cities, the underground pipe networks in some old urban areas have gradually been unable to meet the requirements of existing cities. And with the country's increasing emphasis on environmental protection issues, the drainage pipes that used to combine rain and sewage are also in the process of being phased out, which has spawned a large number of urban underground pipe network renovation projects. Water quality needs to be checked constantly, and getting water is a more troublesome problem. [0003] The invention is mainly applicable to the stage when the project is about to be accepted and d...
