The inner wall of the conical block 84 slides on the circumferential surface of the locking column 83. During installation, the worker aligns the housing 1 and chassis 2 with the bottom end of the electric multi-stage telescopic rod 3 using the handle. The worker lifts the device upwards, and pushes the device to move the locking column 83 upwards along the inner wall of the electric multi-stage telescopic rod 3. Pushing the spring telescopic column 82 upwards allows it to slide within the chuck 81. When the round block at the top of the locking column 83 is fully inserted into the electric multi-stage telescopic rod 3, the spring telescopic column 82 springs out to the right due to its elasticity, locking the round block above the locking column 83 into the interior of the electric multi-stage telescopic rod 3, thus completing the installation of the device. The disassembly mechanism 8 also includes: a disc 85, a protrusion 86, and a push column 87. The lower surface of the disc 85 is fixedly connected to the top of the support column on the inner wall of the liquid storage box 53.

To prevent ice buildup on the inner wall of the cone block 84, which would affect the removal effect, the worker lifts the handle upwards when the sampling is complete. The base 2 drives the locking column 83, which in turn moves the cone block 84 upwards. The cone block 84 pushes the spring telescopic column 82 to retract. When the cone block 84 has completely passed, the spring telescopic column 82 slides on the cone surface of the cone block 84 due to its elasticity. The worker then pulls the handle downwards to push the device out, thus detaching the device from the electric multi-stage telescopic rod 3. This device allows for easy removal and installation of the box 1, facilitates transportation during long-distance transport, and is simple to install.

[0030] Working principle: When the baffle plate 56 moves forward, it drives the trapezoidal slider 73 to move forward. The forward movement of the trapezoidal slider 73 drives the trapezoidal slide column 74 to move to the left. When the trapezoidal slide column 74 moves to the left, the roller on the trapezoidal slide column 74 pushes the inclined plate on the upper surface of the square plate 76 to move forward. The square plate 76 drives the fixed column 75 to move on the inner wall of the slide rail 72. The fixed column 75 drives the brush plate 77 to brush on the filter screen on the left side of the filter box 71. The filter box 71 prevents water plants and other debris from entering the housing 1. In addition, the device can automatically remove water plants and other debris from the filter screen of the filter box 71 through the brush plate 77, preventing water plants from entering. The water inlet pipe 6 affects the detection effect. The movement of the brush plate 77 can drive the rotating rod 78 to rotate. The rotation of the rotating rod 78 drives the connecting column 79 to rotate. The rotation of the connecting column 79 drives the stirring plate 710 to rotate. The rotation of the stirring plate 710 causes the spring piece 711 to vibrate on the filter screen inside the filter box 71. This device can work under harsher environmental conditions. In cold polar regions or high-altitude mountainous areas, the water temperature is extremely low, the water flow inside the filter screen is small, the filter screen holes are small, and ice may form inside the filter box 71. The spring piece 711 can tap the filter screen and stir the stirring plate 710 to make the water inside the filter box 71 flow, effectively preventing ice formation.

[0031] During installation, the worker aligns the housing 1 and base 2 with the bottom of the electric multi-stage telescopic rod 3 using the handle. The worker then lifts the device upwards, pushing it to move the locking pin 83 upwards along the inner wall of the electric multi-stage telescopic rod 3. The locking pin 83 pushes the spring telescopic pin 82 upwards, causing it to slide within the chuck 81. When the round block at the top of the locking pin 83 is fully inside the electric multi-stage telescopic rod 3, the spring telescopic pin 82 springs out to the right due to its elasticity, locking the round block above the locking pin 83 into the interior of the electric multi-stage telescopic rod 3, thus completing the installation. During removal, the device can rotate via the liquid storage box 53, causing the disc 85 to rotate. The rotation of the disc 85 causes the protrusion 86 to rotate, which in turn moves the push pin.

[0032] 87. The push column 87 slides up and down on the inner wall of the chassis 2. The movement of the push column 87 drives the cone block 84 to move up and down. When working in cold water, the cone block 84 can be pushed by the protrusion 86 to prevent the inner wall of the cone block 84 from freezing and affecting the removal effect. When the sampling is completed, the worker lifts the handle upwards, the chassis 2 drives the locking column 83, the locking column 83 drives the cone block 84 to move upwards, the cone block 84 pushes the spring telescopic column 82 to retract. When the cone block 84 has completely passed, the spring telescopic column 82 slides on the cone surface of the cone block 84 due to elasticity. The worker then pulls the handle downwards to push the device out, realizing that the device is detached from the electric multi-stage telescopic rod 3. This device can easily remove and install the box 1, and can be easily transported and installed when transporting the device over long distances.
