Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Please refer to figure 1 and figure 2 ,in, figure 1 A structural schematic diagram of a preferred embodiment of the equipment provided by the present invention that can extract groundwater and prevent backflow; figure 2 for figure 1 Schematic diagram of the structure of the anti-backflow mechanism shown. The equipment capable of extracting groundwater and preventing backflow includes: a box body 1, a drainage mechanism 4, an anti-backflow mechanism 5, an overflow pipe 7, and a water injection pipe 8. The inside of the box body 1 is divided into an overflow chamber 2 and a water injection chamber 3 by partitions. And the overflow chamber 2 is on one side of the top of the water injection chamber 3, and a plurality of evenly distributed communication holes 9b are provided on the partition plate in the water injection chamber 3, and a filter s...

Abstract

The invention provides equipment capable of pumping underground water and preventing backflow. The equipment capable of pumping the underground water and preventing backflow comprises a box body, a drainage mechanism, a backflow-preventing mechanism, an overflow pipe and a water injection pipe; the interior of the box body is cut into an overflow cavity and a water injection cavity through a partition plate, and a one-way vent valve a is fixedly mounted at the corresponding top of the water injection cavity; the backflow-preventing mechanism is mounted in the water injection cavity and comprises a water inlet pipe, a floating ball, a connecting line and a drainage through hole; the water inlet pipe is vertically arranged in the water injection cavity, the bottom of the water inlet pipe extends out of the bottom wall of the water injection cavity and is fixedly provided with a water inlet flange, and the top of the water inlet pipe is attached to the inner top wall of the water injection cavity; and the floating ball is arranged in the water inlet pipe and connected with the inner top wall of the water injection cavity corresponding to the water inlet pipe through the connecting line. The equipment capable of pumping the underground water and preventing backflow has the advantage of underground water backflow preventing capacity.

Description

technical field [0001] The invention relates to the technical field of groundwater pumping, in particular to a device capable of pumping groundwater and preventing backflow. Background technique [0002] Ground water refers to the water that exists in the rock voids below the ground. In a narrow sense, it refers to the water in the saturated aquifer below the groundwater surface. In the national standard "Hydrogeological Terminology" (GB / T14157-93) , Groundwater refers to various forms of gravity water buried below the surface of the earth. Among them, groundwater is an important part of water resources. Due to its stable water quantity and good water quality, it is one of the important water sources for agricultural irrigation, industrial mining and cities, but under certain conditions Under the circumstances, changes in groundwater will also cause unfavorable natural phenomena such as swamp, salinization, landslides, and land subsidence; and the existing groundwater extrac...
