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.
