The sealing component 32 includes a disc 321 that slides against the inner wall of the sampling tank 111 and is connected to the driving component. A sealing block 322 is fixedly connected to the bottom of the disc 321. The sealing block has a movable sealing fit with the inner wall of the sampling tank. For example, the sealing block is made of rubber and has an interference fit with the inner wall of the sampling tank, or the circumferential surface of the sealing block has a groove with an O-ring installed inside. By setting up the water suction part 3, the electric telescopic rod 311 drives the sealing component 32 to realize the automatic suction and discharge of water samples, replacing manual operation and thus improving the convenience and accuracy of sampling.

[0018] Two counterweights are installed on the outer wall of the sampling tank 111, and a rope 113 is installed on the top of the sampling tank. The counterweights can be installed or removed as needed, allowing the sampling tank to sample at different water depths. The rope is used to operate the release and retrieval of the sampling tank.

[0019] The quick-change unit 2 includes: two snap-fit ​​assemblies 21 symmetrically distributed about the bottom center of the sampling tank; each snap-fit ​​assembly 21 includes a rectangular groove 211 radially opened in a through hole; a spring telescopic rod 212 is fixedly connected to the inner wall of the rectangular groove away from the through hole; a slider 213 adapted to the inner wall of the rectangular groove is fixedly connected to the end of the spring telescopic rod near the through hole; a rectangular rod 214 is fixedly connected to the side of the slider facing the through hole; a sliding groove 216 communicating with the outside is opened at the bottom of the rectangular groove; and a toggle member extending from the sliding groove is provided at the bottom of the slider 213; and a filter assembly 22, which includes: a retaining ring 221 fixedly connected to the inner wall of the water inlet and located above the rectangular groove; a filter screen 222 matching the inner diameter of the water inlet is provided at the bottom of the retaining ring 221; and two snap-fit ​​grooves 223 adapted to the rectangular rod are opened on the outer wall of the filter screen. By setting up the quick-change unit 2, the filter 223 can be quickly disassembled and installed without complicated tools, which greatly improves the efficiency of replacing the filter 223 during the sampling interval, while ensuring the stability of the filter 223 after installation and ensuring the filtration effect during subsequent sampling.

[0020] The drive assembly 31 includes an electric telescopic rod 311 fixedly connected to the top of the sampling tank 111 and extending into the sampling tank, wherein the output shaft of the electric telescopic rod 311 is fixedly connected to the center of the disk.

[0021] The top of the sampling container 111 is connected to several evenly distributed air bladders 312.

[0022] The actuating element is a toggle block 215.

[0023] It should be noted that the control of the electric telescopic pole 311 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0024] One specific application of this embodiment is as follows: In use, the sampling tank 111 is placed in the water body to be sampled via rope 113. The electric telescopic rod 311 is activated to retract, causing the disc 321 and the sealing block 322 fixed to its bottom to move upward inside the sampling tank 111. This movement creates a negative pressure in the space of the sampling tank 111 below the sealing block 322, thereby forcing the external water body into the tank through the water inlet 114. At this time, several air bladders 312 are inflated by the forced air. The water body is filtered by the filter screen 223 during the entry process. After sampling is completed, the sampling tank 111 is retrieved via rope 113. The electric telescopic rod 311 is then extended, pushing the disc 321 and the sealing block 322 downward, thus releasing the water sample collected in the tank from the sampling tank 111. 1. When the air is discharged from the bottom, several airbags 312 contract. When replacing the filter 223, simultaneously move two levers 215 away from each other in opposite directions. Lever 215 drives the corresponding slider 213 to slide away in the rectangular groove 211. During this process, the spring telescopic rod 212 is compressed and the rectangular rod 214 is pulled out of the slot 224 on the filter 223. At this time, the old filter 223 can be removed upward along the rectangular groove 211. Place the new filter 223 into the rectangular groove 211 and position it in place. Release the two levers 215. The compressed spring telescopic rod 212 rebounds and pushes the slider 213 and the rectangular rod 214 to move inward, so that the rectangular rod 214 is inserted into the slot 224 on the new filter 223, thereby completing the replacement of the filter 223.
