Collection device and method based on anti-pollution underground water

Abstract

The invention discloses a collection device and method based on anti-pollution underground water, and belongs to the technical field of underground water collection devices. The invention discloses the collection device and method based on anti-pollution underground water, the device comprises a pipe body, the top surface of the pipe body is connected with a cable, the outer wall of the upper end of the pipe body is sleeved with a sealing sleeve, the outer wall of the lower end of the pipe body is of an annular structure and is provided with a plurality of placement grooves, the inner wall of the upper end of the pipe body is fixedly provided with a motor, the output end of the motor is connected with an adjusting assembly, by arranging a protection assembly, when the device is placed at a sampling position, the motor is utilized to drive a threaded rod to rotate, so that an adjusting plate is in contact with the bottom surface of a supporting plate, the adjusting plate is of a conical structure, so that the supporting plate is moved out of a placing groove, the supporting plate can support a hole wall, and meanwhile, the separated supporting plate can pull a protective net open to further support and protect; and the hole wall at the collection position is effectively reinforced, the hole wall is prevented from collapsing in the collection process, sample collection is not affected, and the sample collection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of groundwater collection devices, and more specifically, to a collection device and method based on anti-pollution groundwater. Background technique [0002] Groundwater is a precious natural resource. It is an active factor in the natural environment. Groundwater not only has an indispensable use value in human survival and development, industry, and agriculture, but also bears the responsibility of storing water sources and balancing water. The role of resources is to participate in the water cycle. China is facing the problems of water shortage and water source pollution. The worsening water crisis in China not only exists in rivers and lakes and other places, but also the groundwater crisis is becoming more and more serious. Polluted groundwater is eroding people's health. Thereby it is more important to study the water source. Prior art CN203785927U is a kind of groundwater collector in mining area. T...

But this device also has the disadvantage that when the device is used, due to the existing groundwater collection, by punching, and then the collection device is placed through the hole to the required depth to collect water samples, because when the hole is full of When the water is in the water, the structure of the hole wall will be loose, and it will easily collapse when collecting, which will affect the collection. However, the device has a simple structure and cannot support the hole wall when collecting. Other underwater water sampling devices in the prior art Set the opening control drive mechanism and the controllable external expansion plate to support the inner wall of the water intake hole, but the action of the controllable external expansion plate still needs a drive mechanism, so the volume of the entire water intake device is large and the cost is high. In view of this, We propose a collection device and method based on anti-pollution groundwater
