A control box is arranged on the top of the floating board. A control system and a depth adjustment cylinder are arranged in the control box. The push rod of the depth adjustment cylinder passes downward through the floating board and is fixedly connected to the top of the sampling cavity. A counterweight block and a water depth sensor are arranged at the bottom of the sampling cavity. A plurality of independent sampling devices are arranged in the sampling cavity. The control system includes a controller. The water depth sensor, the depth adjustment cylinder, the sampling cylinder, the water inlet solenoid valve, and the water outlet solenoid valve are all electrically connected to the controller.

There are multiple openings in the water absorption box 705. When the electric push rod 709 moves to drive the moving plate 708 to move, multiple openings can be opened, and the openings of the water absorption box 705 are on different horizontal planes, enabling the device to extract groundwater at different horizontal planes, improving the detection accuracy of the device, being able to comprehensively understand the water quality status of groundwater, and improving the accuracy of the device in subsequent data statistics.

[0016] The driving mechanism 8 includes a cross bar 801, a rotating column 802, a dredging plate 803, and a roller column 807. The cross bar 801 is fixedly connected to the circumferential surface of the first connecting column 710. The rotating column 802 is rotatably connected to the inner wall of the cross bar 801. The dredging plate 803 is fixedly connected to the circumferential surface of the rotating column 802. The roller column 807 is rotatably connected to the inner wall of the cross bar 801. When the device is started, after the water suction box 705 has reached the required sampling depth, the electric push rod 709 drives the first connecting column 710 to move at this time. The movement of the first connecting column 710 will also drive the cross bar 801 to move. The movement of the cross bar 801 will drive the rotating column 802 to move. The movement of the rotating column 802 will drive the dredging plate 803 to move. After the groundwater enters the water suction box 705, the groundwater will push the dredging plate 803, and the groundwater will push the dredging plate 803 to rotate.

After the sampling of the device is completed, the sampling area will rise as a whole. At this time, the water suction box 705 will reach above the water surface through the first reciprocating lead screw 701. At this time, during the movement of the cross bar 801, the movement of the cross bar 801 will drive the second connecting column 804 to move. The movement of the second connecting column 804 will drive the semi-circular scraping plate 805 to move. At the same time, the second connecting column 804 will also drive the horizontal scraping plate 808 to move. The semi-circular scraping plate 805 will first scrape off the sundries on the surface of the filter plate 806, and the scraped sundries will fall on the inner wall of the connecting block 704. The movement of the horizontal scraping plate 808 will push the sundries to move. At the same time, after the connecting block 704 moves up to the highest point, the straight rod 811 will contact the box body 3. The straight rod 811 will be squeezed to push the telescopic end of the second elastic telescopic rod 809. The telescopic end of the second elastic telescopic rod 809 will squeeze and push the hinge plate 810. The second elastic telescopic rod 809 will cause the hinge plate 810 to rotate. The rotation of the hinge plate 810 will open the opening at the bottom of the connecting block 704.At this time, the thrust of the horizontal scraper 808 and the flow of water can cause the sundries inside the connecting block 704 to be discharged through the opening opened by the hinge plate 810 area, improving the service life of the device, avoiding blockage of the device, and reducing the manual dredging cost.

[0017] Working principle: When the device is in use, a worker or a robotic arm places the device on the water surface, and the buoyancy plate 2 will float on the water surface. At this time, the bidirectional motor 4 will start, and the bottom output end of the bidirectional motor 4 will drive the reciprocating lead screw 701 to rotate. The rotation of the reciprocating lead screw 701 will drive the moving block 702 to rotate. However, the moving block 702 is limited by the limiting column 703. At this time, the moving block 702 will move up and down through the reciprocating groove on the surface of the reciprocating lead screw 701. The up and down movement of the moving block 702 will drive the connecting block 704 to move up and down, and the movement of the connecting block 704 will drive the water suction box 705 to move. The up and down movement of the water suction box 705 can suck and collect sample water sources at different depths. By sampling at different depths, specific water quality data of each layer of groundwater can be obtained, thereby providing accurate basic information for subsequent water resource management, environmental protection, and water pollution prevention and control, improving the sampling accuracy of the device during detection. When the water suction box 705 reaches the area where sampling is required at a certain depth, at this time, the telescopic end of the electric push rod 709 will move. The movement of the telescopic end of the electric push rod 709 will drive the connecting column 710 to move, and the movement of the connecting column 710 will also drive the connecting long rod 711 to move. The movement of the connecting long rod 711 will drive the moving plate 708 to move. The downward movement of the moving plate 708 will squeeze the elastic telescopic rod 707. At this time, the movement of the moving plate 708 will open the opening on the surface of the water suction box 705. At this time, the water pump inside the detection tank 5 will draw the sampled water inside the water suction box 705 into the detection tank 5 through the water pipe 10 for detection. There are multiple openings on the water suction box 705. When the electric push rod 709 moves to drive the moving plate 708 to move, multiple openings can be opened, and the openings of the water suction box 705 are on different horizontal planes, enabling the device to draw groundwater at different horizontal planes, improving the detection accuracy of the device, comprehensively understanding the water quality status of groundwater, and improving the accuracy of subsequent data statistics of the device.

[0018] When the device is started, after the water absorption box 705 has reached the depth where sampling is required, the electric push rod 709 drives the first connecting column 710 to move at this time. The movement of the first connecting column 710 will also drive the cross bar 801 to move. The movement of the cross bar 801 will drive the rotating column 802 to move. The movement of the rotating column 802 will drive the dredging plate 803 to move. After the groundwater enters the water absorption box 705, the groundwater will push the dredging plate 803, and the groundwater will push the dredging plate 803 to rotate. The rotation and movement of the dredging plate 803 can dredge the extraction area of the water pipe 10, avoid the accumulation of impurities and soil in the groundwater in the connecting block 704, thereby causing blockage inside the connecting block 704, avoid the sampler of the device from being blocked, improve the extraction speed of the sample water, improve the use efficiency of the device. After the sampling of the device is completed, the sampling area will rise as a whole. At this time, the water absorption box 705 will reach above the water surface through the first reciprocating screw rod 701. At this time, during the movement of the cross bar 801, the movement of the cross bar 801 will drive the second connecting column 804 to move. The movement of the second connecting column 804 will drive the semi-circular scraper 805 to move. At the same time, the second connecting column 804 will also drive the horizontal scraper 808 to move. The semi-circular scraper 805 will first scrape off the sundries on the surface of the filter plate 806, and the scraped sundries will fall on the inner wall of the connecting block 704. The movement of the horizontal scraper 808 will push the sundries to move. At the same time, after the connecting block 704 moves up to the highest point, the straight rod 811 will contact the box body 3. The straight rod 811 will be squeezed to push the telescopic end of the second elastic telescopic rod 809. The telescopic end of the second elastic telescopic rod 809 will squeeze and push the hinged plate 810. The second elastic telescopic rod 809 will cause the hinged plate 810 to rotate. The rotation of the hinged plate 810 will open the opening at the bottom of the connecting block 704. At this time, the thrust of the horizontal scraper 808 and the flow of water can make the sundries inside the connecting block 704 drain through the opening opened by the hinged plate 810, improve the service life of the device, avoid the device from being blocked, and reduce the manual dredging cost.

[0019] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, the cleaning mechanism 9 includes a first gear 901, a second gear 902, a reciprocating lead screw two 903, a fixed ring 904, an elastic telescopic rod three 905, a sealing block 906, and a sponge block 907. The first gear 901 is fixedly connected to the output end of the bidirectional motor 4. The reciprocating lead screw two 903 is rotatably connected to the inner wall of the detection tank 5. The second gear 902 is fixedly connected to the circumferential surface of the reciprocating lead screw two 903. The fixed ring 904 is fixedly connected to the inner wall of the detection tank 5. The elastic telescopic rod three 905 is fixedly connected to the inner wall of the detection tank 5. The sealing block 906 is fixedly connected to the telescopic end of the elastic telescopic rod three 905. The sealing block 906 is movably connected to the circumferential surface of the reciprocating lead screw two 903. The sponge block 907 is fixedly connected to the bottom of the sealing block 906. When the device is started, the water pump inside the detection tank 5 extracts the sample water into the detection tank 5 through the water pipe 10. At this time, the top output end of the bidirectional motor 4 drives the first gear 901 to rotate. The rotation of the first gear 901 drives the second gear 902 to rotate. The rotation of the second gear 902 drives the reciprocating lead screw two 903. The rotation of the reciprocating lead screw two 903 drives the sealing block 906 to rotate. However, the sealing block 906 is restricted by the elastic telescopic rod three 905. At this time, the sealing block 906 reciprocates up and down through the reciprocating groove on the surface of the reciprocating lead screw two 903. The up and down movement of the sealing block 906 drives the sponge block 907 to move up and down. At the same time, the movement of the sealing block 906 drives the sponge block 907 to move. The reciprocating up and down movement of the sponge block 907 can wipe the water stains on the inner wall of the detection tank 5, avoiding the residual water stains inside the detection tank 5 after the water quality detection is completed. When the sponge block 907 moves up and then down, the sponge block 907 can cooperate with the restoring force of the elastic telescopic rod three 905 to squeeze the elastic telescopic rod three 905. At this time, the sample water inside the elastic telescopic rod three 905 can be squeezed out, and the sample water can be discharged through the opening on the surface of the detection tank 5, which can avoid the deviation of the subsequent detection accuracy caused by the failure of the sample water to be discharged in time and cleaned, improving the integrity of the water quality detection. The cleaning mechanism 9 further includes an elastic telescopic rod four 908, a sliding block 909, and an inclined block 910. The elastic telescopic rod four 908 is fixedly connected to the inner wall of the box body 3. The sliding block 909 is fixedly connected to the telescopic end of the elastic telescopic rod four 908. The inclined block 910 is fixedly connected to the inner wall of the sliding block 909. The first gear 901 meshes with the second gear 902. The sliding block 909 is slidably connected to the inner wall of the box body 3. The reciprocating lead screw two 903 is rotatably connected to the inner wall of the box body 3. The sponge block 907 is slidably connected to the inner wall of the detection tank 5. During the rising process of the straight rod 811, after the straight rod 811 moves a certain distance, the straight rod 811 contacts and squeezes the inclined block 910. After the inclined block 910 is subjected to the squeezing force, the inclined block 910 moves. The movement of the inclined block 910 drives the sliding block 909 to move. At this time, the sliding block 909 can guide the sample water discharged from the detection tank 5, and at the same time, the movement of the sliding block 909 can accelerate the discharge of the sample water.Improve the discharge speed of the sample water after detection and enhance the water quality detection efficiency.

[0020] Working principle: When the device is started, the water pump inside the detection tank 5 extracts the sample water into the detection tank 5 through the water pipe 10. At this time, the top output end of the bidirectional motor 4 drives the first gear 901 to rotate. The rotation of the first gear 901 drives the second gear 902 to rotate. The rotation of the second gear 902 drives the reciprocating screw rod two 903. The rotation of the reciprocating screw rod two 903 drives the sealing block 906 to rotate. However, the sealing block 906 is restricted by the elastic telescopic rod three 905. At this time, the sealing block 906 reciprocates up and down through the reciprocating groove on the surface of the reciprocating screw rod two 903. The up and down movement of the sealing block 906 drives the sponge block 907 to move up and down. At the same time, the movement of the sealing block 906 drives the sponge block 907 to move. The reciprocating up and down movement of the sponge block 907 can wipe the water stains on the inner wall of the detection tank 5, avoiding the residual water stains inside the detection tank 5 after the water quality detection. When the sponge block 907 moves up and then moves down, the sponge block 907 can cooperate with the reset force of the elastic telescopic rod three 905 to squeeze the elastic telescopic rod three 905. At this time, the sample water inside the elastic telescopic rod three 905 can be squeezed out. The sample water can be discharged through the opening on the surface of the detection tank 5, which can avoid the deviation of the subsequent detection accuracy caused by the failure to discharge and clean the sample water in time, improving the integrity of the water quality detection. During the rising process of the straight rod 811, after the straight rod 811 moves a certain distance, the straight rod 811 contacts and squeezes the inclined block 910. After being squeezed, the inclined block 910 moves. The movement of the inclined block 910 drives the sliding block 909 to move. At this time, the sliding block 909 can guide the sample water discharged from the detection tank 5, and at the same time, the movement of the sliding block 909 can accelerate the discharge of the sample water, improve the discharge speed of the sample water after detection, and enhance the water quality detection efficiency.
