Deep well structure and use method thereof

Abstract

The invention relates to a deep well structure and a use method thereof. The deep well structure comprises a well pipe, a suction pipe of which one end is arranged in the well pipe, a submersible pump which is arranged in the well pipe and connected with the suction pipe and an electrical power cable connected with the submersible pump. The deep well structure is characterized by further comprising a connecting flange and a fixing flange, the connecting flange is fixed on the edge of the outer side of a well mouth of the well pipe, the fixing flange is fixedly connected with the connecting flange through fixing bolts and seals the well mouth, the suction pipe and the electrical power cable penetrate through the fixing flange and are in seal connection with the fixing flange, and a control valve is arranged on the portion, on the outer side of the well pipe, of the suction pipe in series. According to the structure, the submersible pump is matched with the suction pipe to pump well water out of the well pipe, after the well water is completely pumped out, the control valve on the suction pipe is switched off, and a vacuum and negative-pressure closed space is formed due to water suction in the well pipe; meanwhile, water in a surrounding environment flows into the well pipe through suction formed by the vacuum and negative-pressure closed space in the well pipe, and the water volume in the well pipe is replenished.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a deep-water well structure and a use method thereof. Background technique [0002] The factories that have no conditions to use tap water now still use the well pipes drilled in the factory area. However, the well pipes have been used for many years, and the water level will easily cause insufficient water, which will affect normal production and domestic water and easily burn the motor of the submersible pump. Forced to abandon the well pipe and find an engineering team to drill again, resulting in waste of resources and huge investment. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide a deep-water well structure that realizes negative pressure water absorption. [0004] The technical solution adopted by the present invention to solve its technical pr...
