Between the water extraction head 503 and the first winch 502, there is a first steel cable 504 connected by a rope. One end of the first steel cable 504 is connected to the outer surface of the water extraction head 503, and the other end is connected and wound around the first winch 502. On the outer surface of the first steel cable 504, there is a first sleeve 505. The first steel cable 504 passes through the inner surface of the first sleeve 505. The first sleeve 505 has three arc-shaped bends, which are used to support and guide the first steel cable 504. The first sleeve 505 is fixedly connected to the upper part of the bottom plate 1 and the front of the support frame 2. On the outer surface of the first sleeve 505, there are two fixed seats for fixing on the bottom plate 1 and the support frame 2. Below the support frame 2, there is a fixed electric push rod 506. At the lower end of the electric push rod 506, there is a connecting piece 507 fixedly connected. The connecting piece 507 is fixedly connected to the left side of the water extraction head 503. The electric push rod 506 can push the connecting piece 507 to lower the water extraction head 503 so as to extend into different depths of the wastewater. Below the water extraction head 503, there is a blocking component 6 for blocking impurities in the water, and a scraping component 7 for cleaning impurities in the water. Above the bottom plate 1, there is a fixed support plate 508. Above the support plate 508, there is a fixed second sleeve 509. The second sleeve 509 has three arc-shaped bends, which are used to support and guide the second steel cable 510. The second sleeve 509 is fixedly connected to the upper part of the bottom plate 1. On the second sleeve 509, there is a fixed seat for fixing on the bottom plate 1. Inside the inner surface of the second sleeve 509, there is a second steel cable 510. The second steel cable 510 passes through the inner surface of the second sleeve 509.The left end of the second steel cable 510 is fixedly connected to a second winch 511. The second steel cable 510 is connected to and wound around the second winch 511. The second winch 511 is fixedly connected to the outer surface of the rotating column 5. The second winch 511 is arranged above the first winch 502. The lower end of the second steel cable 510 is fixedly connected to a counterweight 512. A slide rail 513 is slidably connected to the left side of the counterweight 512. The cross-sectional shape of the slide rail 513 is trapezoidal. A dovetail groove for sliding on the slide rail 513 is formed on the left side of the counterweight 512. The slide rail 513 is fixedly connected to the right side of the support plate 508. Universal wheels 8 are rotatably connected below the bottom plate 1. The number of the universal wheels 8 is four, which are respectively arranged at the four corners below the bottom plate 1. A push rod 9 is fixedly connected above the bottom plate 1. The shape of the push rod 9 is U-shaped. A toolbox 10 is fixedly connected above the bottom plate 1.,

[0025] When the above-mentioned device is in specific use, first, push the bottom plate 1 through the push rod 9 to make it move under the action of the universal wheels 8, move it to the side of the wastewater, and ensure that the water suction head 503 is above the wastewater. Then, start the electric push rod 506 to make it extend, thereby driving the connecting piece 507 to descend. The descent of the connecting piece 507 will drive the water suction head 503 to descend and insert it into the wastewater. At this time, turn on the water pump 3 to make the water suction head 503 extract the wastewater. The extracted wastewater will fall into the sample placement tray 501 through the water outlet pipe 4. At this time, continue to start the electric push rod 506 to drive the connecting piece 507 to continue to descend, so that the water suction head 503 descends uniformly to a deeper part of the wastewater. The descent of the water suction head 503 will pull the first steel cable 504, and the first steel cable 504 will drive the first winch 502 to rotate clockwise. The clockwise rotation of the first winch 502 will drive the rotating column 5 to rotate clockwise. The clockwise rotation of the rotating column 5 will drive the sample placement tray 501 to rotate clockwise, so as to rotate the sample placement tray 501 when the water suction head 503 descends to switch different sample storage areas, so as to classify and arrange the wastewater pumped from different depths. When the rotating column 5 rotates clockwise, it will also drive the second winch 511 to rotate clockwise. The clockwise rotation of the second winch 511 will pull the second steel cable 510, and the second steel cable 510 will pull the counterweight 512 to rise. The counterweight 512 will slide upward on the slide rail 513. At this time, the weight of the counterweight 512 will exert a pulling force on the second steel cable 510. When the sampling is completed, drive the connecting piece 507 to rise by the contraction of the electric push rod 506 to make the water suction head 503 rise from the water. At this time, as the water suction head 503 rises, the first steel cable 504 will be released, and the counterweight 512 will descend under the action of gravity and pull the second steel cable 510 to make the second winch 511 rotate counterclockwise. The counterclockwise rotation of the second winch 511 will drive the rotating column 5 to rotate counterclockwise. The counterclockwise rotation of the rotating column 5 will drive the first winch 502 to rotate counterclockwise, so as to wind up the first steel cable 504 until the first steel cable 504 is tightened. The counterclockwise rotation of the rotating column 5 will drive the sample placement tray 501 to rotate counterclockwise, so as to reset it for the next sampling. Embodiment

The right end of the first hydraulic rod 605 is fixedly connected to a sliding ball 606. A spring 611 is elastically connected between the sliding ball 606 and the first hydraulic chamber 604. The spring 611 is arranged on the outer surface of the first hydraulic rod 605. One end of the spring 611 is connected to the right side of the first hydraulic chamber 604, and the other end is connected to the outer surface of the sliding ball 606. The spring 611 will exert elasticity to push the sliding ball 606 toward the toggle protrusion 608 under normal conditions, and the bottom plate 1 is rotated above the connection There is a rotating rod 607, and a toggle protrusion 608 is fixedly connected to the outer surface of the rotating rod 607.

When the toggle protrusion 608 pushes against the sliding ball 606, the sliding ball 606 drives the first hydraulic rod 605 to extend into the first hydraulic chamber 604 and squeeze the spring 611. When the protrusion on the toggle protrusion 608 leaves the sliding ball 606, the squeezed spring 611 releases the elastic force to make the sliding ball 6 06 is reset, thereby driving the first hydraulic rod 605 to extend from the first hydraulic compartment 604, and the first hydraulic rod 605 is continuously extended and retracted in the first hydraulic compartment 604 to push the liquid, thereby driving the second hydraulic rod 602 to continuously extend and retract in the second hydraulic compartment 601. At this time, the second hydraulic rod 602 will continue to rise and fall repeatedly in a small range, and the repeated rise and fall of the second hydraulic rod 602 will drive the filter sleeve 603 to shake up and down under the pumping head 503. The filter sleeve 603 will filter out large impurities in the wastewater, and the impurities attached to the filter sleeve 603 will be shaken off by the up and down shaking of the filter sleeve 603, thereby preventing impurities from clogging the filter sleeve 603 and causing the pumping head 503 to be blocked and unable to extract wastewater.
