AI Technical Summary
In the prior art, the sealing effect of the sealing cover depends on the weight of the counterweight, which results in a large force required to open the sealing cover. In addition, if the counterweight is not heavy enough, the accuracy of the sampling depth will be affected.
A detection and sampling device was designed, including a base, a support part, a measuring part and a transmission part. The transmission part drives the sampling barrel to adjust the depth, and the barrel lid automatically moves back to form a seal after being opened. Friction resistance is used to prevent the sampling barrel from moving upward, and a telescopic rod is combined to achieve convenient opening and sealing.
The precise control of sampling depth is achieved, which avoids the depth change caused by opening the barrel cover and ensures the accuracy and repeatability of the sampling results.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Specifically, the base 1 is a triangular seat, which is horizontally pre-buried at the bottom of the water body to be measured. The support part 2 supports the measuring part 4. The support part 2 is slidably connected to the base 1, so that the measuring part 4 can be driven to adjust its height to adapt to the changes in the depth of the water body at different times. The sampling bucket 6 is clamped on the transmission part 5. The transmission part 5 is started to drive the sampling bucket 6 to adjust and change its own depth in the water body so as to sample samples of different depths in the water body. The adjustment part 3 adjusts and changes the height of the support part 2, and a pull rope is used to pull open the bucket cover 61. Since the bucket cover 61 is limitedly connected to the transmission part 5, when the bucket cover 61 is pulled open, the friction resistance of the transmission part 5 itself can avoid the defect of the sampling bucket 6 moving up and changing its depth due to pulling the pull rope. After the sampling is completed, the stretching is released, and the telescopic rod 62 is reset, driving the bucket cover 61 to automatically close and seal with the sampling bucket 6 to avoid water samples of other depths from seeping into the sampling bucket 6 when the sampling bucket 6 is moved up after sampling.
[0028] The support portion 2 includes a column, and the adjustment portion 3 includes a plurality of support rods 31 . One end of the support rod 31 is rotatably connected to the column, and the other end of the support rod 31 is rotatably connected to a slider 32 . The slider 32 is slidably connected to the base 1 .

[0031] Specifically, the first T-shaped block 33 slides in the first T-shaped slot 11, so that the slider 32 can slide stably on the base 1, and the first T-shaped block 33 and the first T-shaped slot 11 fit tightly together, so that the friction resistance between them is large, so that the column will not easily change its height, and the friction resistance between the first T-shaped block 33 and the first T-shaped slot 11 is greater than the pulling force generated when the pull rope pulls the barrel cover 61 to open it.
[0032] The upper surface of the base 1 is fixedly connected with a sleeve rod 12 which is sleeved with the column.
[0033] Specifically, the column is sleeved on the sleeve rod 12 so that the column remains perpendicular to the base 1.

A scale 52 is fixedly installed on the side of the conveyor belt, and the limiting sleeve 51 is fixedly connected to the starting point of the scale 52 on the conveyor belt. After starting the conveyor belt, the depth of the sampling bucket 6 entering the water body can be clearly judged by observing the changes in the scale 52, and when sampling, the starting point of the scale 52 is made flush with the water surface.
[0038] The limiting member 8 includes two wedge-shaped blocks 81 whose one end extends into the plug-in rod 7 and is slidably connected thereto. A second spring 83 is provided at one end of the two wedge-shaped blocks 81 close to each other, and both ends of the second spring 83 are fixedly connected to the two wedge-shaped blocks 81 respectively.
[0039] Specifically, the second spring 83 drives the two wedge-shaped blocks 81 to automatically move away from each other, thereby achieving engagement and contact with the limiting sleeve 51 .

The two ends of the first spring 623 are fixedly connected to the first connecting rod 621 and the second connecting rod 622 respectively. A hanging ring 611 is fixedly installed on the top of the barrel cover 61.
[0043] Specifically, one end of the second connecting rod 622 close to the first connecting rod 621 is inserted into the first connecting rod 621 and slidably connected thereto.
