The working principle is as follows: when the device works, in the prior art, a sampling device is deeply inserted into water through a floating and diving mechanism when water is sampled, the floating and diving mechanism can enable water to flow greatly when moving in the water, the water with different depths can be mixed to a certain extent, and large errors can be generated when the water is sampled, so that the detection of the water with different depths is inaccurate, when the water is required to be sampled and detected, the length of a probe tube 1 is selected according to the depth of the water required to be detected, the length of the probe tube 1 is enabled to be equal to the depth of the water required to be detected, then the probe tube 1 is inserted into the water, an installation block 2 is fixed to a shore, after a short period of time for the water to be calm, an L-shaped installation plate 22 and an air cylinder 21 are installed at the top of the installation block 2, the air cylinder 21 is started to extend downwards, the air cylinder 21 can drive a C-shaped block 17 to move downwards together, the C-shaped block 17 can drive a T-shaped block 16, the T-shaped block 16 will drive the sampling tube 7 to move downwards through the cover plate 15, the sampling tube 7 will drive the sampling slide plate 13 therein to move downwards together, when the sampling tube 7 moves downwards to make the bottom of the sealing slide block 14 fixed on the sampling slide plate 13 contact with the bottom of the detecting tube 1, the sampling slide plate 13 is limited by the detecting tube 1 and does not move downwards, at this time, the sampling tube 7 will still move downwards under the driving of the cylinder 21, a vacuum area will be formed between the sampling tube 7 and the sampling slide plate 13, when the sampling tube 7 drives the movable sealing plate 10 to move downwards to contact with the rubber sealing block 5, the movable sealing plate 10 moves downwards again to drive the rubber sealing block 5 to move downwards in the water inlet 3, when the bottom surface of the movable sealing plate 10 contacts with the inclined surface of the trapezoidal top block 4, the movable sealing plate 10 will move inwards in the first sliding groove 9 under the action of the inclined surface of the trapezoidal top block 4, meanwhile, the water suction port 8 is opened, after the movable sealing plate 10 drives the rubber sealing block 5 to move downwards to a certain distance, the gap of the staggered trapezoidal top block 4 on the rubber sealing block 5 can be separated from the water inlet 3, at the moment, the bottom of the sampling tube 7 moves to be attached to the top surface of the bottom of the detecting tube 1, then water outside the detecting tube 1 can enter the detecting tube 1 from the water inlet 3, as the area below the sampling sliding plate 13 in the sampling tube 7 is in a vacuum state, the water at the position of the water inlet 3 can enter the sampling tube 7 under the action of air pressure, the area between the sampling tube 7 and the sampling sliding plate 13 is rapidly filled up to finish sampling, then the air cylinder 21 can be driven to contract upwards, the air cylinder 21 can drive the T-shaped block 16 and the cover plate 15 to move upwards together through the C-shaped block 17 and the trapezoidal limiting block 19, the cover plate 15 can drive the sampling tube 7 with sampling completion to move upwards together, the movable sealing plate 10 can be separated from the inclined plane of the trapezoidal top block 4, the movable sealing plate 10 can rapidly close the water suction port 8 under the elastic force of the second spring 11, so that the water sampled in the sampling tube 7 can not be lost, and simultaneously the acting force of the movable sealing plate 10 is lost, the rubber sealing block 5 can rapidly return to the water inlet 3 to close the water inlet 3 under the elastic force of the first spring 6, then the air cylinder 21 can drive the sampling tube 7 to move upwards, after the sampling tube 7 moves upwards to be separated from the detecting tube 1, a worker can slide the sampling tube 7 from the C-shaped block 17 to one side, take down the sampling tube 7 and detect the water quality, if the sampling is needed for a plurality of times, a new sampling tube 7 can be installed on the C-shaped block 17 again, and then the actions are repeated, so that the secondary sampling can be realized, through the arrangement of the detecting tube 1 and the sampling tube 7, only the detecting tube 1 needs to be inserted into, then drive sampling tube 7 through actuating mechanism and move down in detecting tube 1, after sampling tube 7 moves down to the bottom, water can enter into sampling tube 7 under the effect of air pressure and accomplish the sample in, this sampling process is very simple, and convenient, and can reduce the surface of water of sampling position greatly through the effect of air pressure and rock, and moisture can resume calmly at once after filling up sampling tube 7 with water, because it is less to fill up the required moisture of sampling tube 7, so the moisture of sampling position does not have too big flow, can make the more accuracy of sample to moisture, can not produce great influence to the sample of next time simultaneously.
