[0036] The inside of the fixed cylinder 1 is provided with a positioning block 10, and the middle of the positioning block 10 is provided with a positioning hole. The bottom of the positioning block 10 is in the shape of an inverted funnel, so that when the upper and lower adjacent two fixed cylinders 1 are fixed, the upper end of the sampling pipe 9 can be smoothly inserted into the inside of the positioning hole from the inverted funnel-shaped bottom of the positioning block 10, so as to position and fix the top of the sampling pipe 9.

[0037] The outer wall of each fixed cylinder 1 is provided with a first water inlet hole 101, and the top of the positioning block 10 is in the shape of a funnel. The upper surface of the positioning block 10 is lower than the first water inlet hole 101. The geothermal water can enter the inside of the fixed cylinder 1 through the first water inlet hole 101, and then gather into the sampling pipe 9 through the funnel-shaped top of the positioning block 10;

[0038] The top of the uppermost fixed cylinder 1 is provided with a connecting block 4, and the bottom of the connecting block 4 is provided with a threaded groove matched with the threaded block 7 at the top of the uppermost fixed cylinder 1.

[0041] The working principle of the geothermal water multilayer water quality detection sampling device is as follows: the cable is installed on the hook of the mounting block 5, then the device is hoisted into the geothermal water through the cable, the device vertically enters the water until all the fixed cylinders 1 are immersed in the water, at this time, the floating ring 3 is subjected to the buoyancy and cannot sink, so as to drive the moving cylinder 2 to slide upwards on the outside of each fixed cylinder 1, so that the second water inlet hole 201 on the moving cylinder 2 corresponds to the first water inlet hole 101 on each fixed cylinder 1 and is connected in communication, so that the geothermal water of different depths enters the sampling tube 9 of different depths in sequence through the second water inlet hole 201 and the first water inlet hole 101.

[0042] After collecting a proper amount of geothermal water, the device is pulled upwards through the cable, the device rises, the floating ring 3 leaves the water surface, and the moving cylinder 2 is lowered under the action of its own gravity, so as to reset the second water inlet hole 201 and the first water inlet hole 101, so that the water inlet holes are closed, thereby sealing the fixed cylinders 1, and avoiding that the geothermal water of different depths enters the inside of the sampling tube 9 during the rising process of the device.
