The outer surface of the sampling bucket 101 is fixedly connected to the inner surface of the support plate 102, and the inner surfaces of the support plate 102 are fixedly connected at both ends. The wall slides in contact with the front surface of the fixed block 103, and the rear surfaces of the two fixed blocks 103 are fixedly connected to the two end surfaces of the elastic block 104. The surface of the elastic block 104 is fixedly connected to the inner wall of the storage block 105.

The counterweight mechanism 2 includes a counterweight block 201, a limiting block 202, a fixing screw 203, and a support base 204. The inner wall of the counterweight block 201 contacts the surface of the limiting block 202, the rear inner wall of the limiting block 202 is rotatably connected to the front surface of the fixing screw 203, and the surface of the fixing screw 203 is threadedly connected to the inner wall of the support base 204. By selecting a counterweight 201 of appropriate weight, the sinking speed and stability of the device can be adjusted according to the sampling requirements of water at different depths, ensuring that the sampling bucket 101 can smoothly reach the predetermined depth and also guaranteeing its stability in the water flow. The upper ends of the limiting block 202 are provided with travel blocks 3 on both sides, and the lower end of the sampling bucket 101 is provided with a guide groove 4. The lower surface of the limiting block 202 is fixedly connected to the upper surface of the limiting block 202. The mounting base 6 is provided with fixing rods 5 on both sides, and the surfaces of the fixing rods 5 are slidably connected to the inner wall of the mounting base 6. The fixing rods 5 can be slidably adjusted within the mounting base 6 as needed to adapt to different soil conditions. The winding machine 9 is connected to the inner wall of the support plate 102 via a winding line. The surface of the fixing block 103 contacts the inner wall of the receiving block 105. The support plate 102... The inner wall is rotatably connected to the upper surface of the receiving block 105. The winding machine 9 is connected to the inner wall of the support plate 102 via a winding line, allowing the operator to control the sinking depth and retrieval speed of the sampling bucket 101.

The guide groove 4 ensures that the travel block 3 can drive the limit block 202 to move smoothly and accurately on the predetermined track.

[0018] The working principle of this utility model: When performing water quality sampling, the mounting base 6 must first be placed stably on the working surface. To ensure the stability of the mounting base 6, the fixing rods 5 on the mounting base 6 are stepped on to sink them into the soil, providing a stable foundation for subsequent operations. After completing the above steps, the sampling bucket 101 is installed. Specifically, the connecting block at the end of the winding line on the telescopic rod 8 is inserted into the support plate 102. Then, the storage block 105 at the bottom of the support plate 102 is rotated. During the rotation, the fixing block 103 inside the storage block 105 will pop out under the action of the elastic block 104 when it encounters the empty slot in the support plate 102, and firmly embed into the predetermined position in the support plate 102, thereby achieving a stable connection between the support plate 102 and the connecting block at the lower end of the winding line. It is worth noting that because the empty slot is designed with a rounded chamfer, the fixing block 103 can smoothly retract into the storage block 105 when rotating in the opposite direction, and then the sampling bucket 101 can be removed. To meet the sampling requirements, a suitable weight of counterweight 201 can be selected based on the actual situation. First, ensure that the upper surface of the counterweight 201 is in close contact with the lower surface of the sampling bucket 101. Then, by rotating the fixing screw 203, the interaction between the screw and the inner wall thread of the support base 204 is used to push the limiting block 202 and the stroke block 3 above it to slide along the guide groove 4 until the limiting block 202 is successfully inserted into the counterweight 201, thus ensuring the stability of the counterweight 201. Since the fixing screw 203 has a self-locking function, it can effectively prevent the counterweight 201 from accidentally falling off during the sampling process. The last step is to adjust the position of the telescopic rod 8 so that it is directly above the sampling point. Use the winding machine 9 to control the release speed and length of the winding line, allowing the sampling bucket 101 to slowly sink into the water to collect water samples from different depths. After sampling, use the winding machine 9 again to pull the sampling bucket 101 filled with water samples back above the water surface for further analysis and processing of the collected water samples.

[0019] The specific models and specifications of the telescopic rod 8, winding machine 9, winding line, elastic block 104, fixing screw 203, and counterweight 201 proposed in this application need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0020] The wiring connection methods and control methods of the telescopic rod 8, winding machine 9, winding line, elastic block 104, fixing screw 203, and counterweight 201 proposed in this application are all existing technologies in this field, and therefore will not be described in detail.
