[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] When the present invention detects wastewater in a water area, since the impurities contained in the wastewater are different, it is necessary to sample wastewater at different depths.

When the wastewater sampling detection is performed, the wastewater at different depths can be sampled and detected, and the comprehensiveness and accuracy in the detection process are increased. It is avoided that during the sampling detection, only the water surface can be sampled and detected, and the underwater with heavy particulate impurities cannot be sampled and detected, resulting in the final detection result being inaccurate and having errors, and further detection is required in the later stage, which increases the time and cost of the detection. In addition, the protection capability of the detection end during the sampling detection is to avoid the detection end extending underwater, resulting in water leakage, short circuit, and damage by impact and entanglement of underwater foreign objects.

[0022] When the wastewater area of ​​the river environment is detected, the present invention places the working floating frame on the river surface by starting the mobile stabilizing mechanism, and then starts the mobile stabilizing mechanism through the transmission adjustment mechanism, and can detect various positions on the upper end of the river surface, thereby increasing the range of river surface sampling detection, and can also increase the stability during mobile sampling detection, avoiding the situation in which only one point in the river water area can be detected during the detection process, increasing the limitation of river detection, and failing to conduct a comprehensive detection of the river water area, resulting in errors between the final detection result and the actual situation.

When sampling, place Solid objects are added to the cavity 506 to increase the weight of the sampling head 501, and the small electric push rod 703 is started to drive the movable extrusion plate 701 to move backward, separate from the bottom end of the water pipe 502, so that the water pipe 502 loses its restraint, and the weight of the sampling head 501 drives the bottom end of the water pipe 502 to move downward, which will tighten the water pipe 502 outside the rotating roller 503, and at the same time drive the moving slider 602 to move to the right outside the movable slider 601, and squeeze the reset spring 604. Later, the reset spring 604 after squeezing drives the moving slider 602 to reset. When the moving slider 602 moves to the right, it contacts the induction switch 605 on the left, and the small electric push rod 703 is started to drive the movable slider 602 to move to the right. The movable extrusion plate 701 moves forward to contact and squeeze the water pipe 502, and fix the water pipe 502. By triggering the induction switch 605 at different positions, the downward position of the sampling head 501 can be determined. When the sampling is completed and recovered, the suction pump 504 and the double-headed electromagnetic valve are started again, and the gas is transported to the inside of the water pipe 502 and the double-headed electromagnetic valve through the reverse rotation of the suction pump 504, and the gas is transported to the inside of the folded airbag 507, so that the folded airbag 507 expands and pushes down the solid matter filled in the placement cavity 506, and the movable baffle 505 is pushed open to discharge the filled solid matter, so that the sampling head 501 loses weight, and loses the restraining force to move downward, and the sampling head 501 automatically The buoyancy of the water pipe 502 and the pushing force of the return spring 604 during rebound can quickly recycle the water pipe 502 and the sampling head 501, so that when sampling and testing wastewater, it is possible to sample and test wastewater at different depths, thereby increasing the comprehensiveness and accuracy of the testing process, and avoiding the situation where only the water surface can be sampled and tested during sampling and testing, while sampling and testing cannot be performed underwater with heavy particulate impurities, resulting in inaccurate final test results and errors, and requiring further testing at a later stage, increasing the time and cost of testing, as well as the protection capability of the testing end during sampling and testing, so as to avoid the testing end extending underwater, resulting in water leakage, short circuit, and damage caused by impact and entanglement of underwater foreign objects;

[0047] The receiving detection mechanism 9 also includes an adsorption sponge 901, an absorption solenoid valve 902, a movable floating ring 905 and a cleaning brush 906. The bottom end of the detection terminal 12 extends into the receiving frame head 903. The movable floating ring 905 is movably arranged at the bottom end of the inner cavity of the receiving frame head 903. The cleaning brush 906 is installed around the inner cavity of the movable floating ring 905. Several adsorption sponges 901 are respectively installed in the sealing frame 904. The bottom end of the receiving frame head 903 is provided with connecting holes around. Several absorption solenoid valves 902 are respectively installed around the receiving frame head 903 at relative positions of the connecting holes. The absorption solenoid valve 902 is electrically connected to the control panel. The front and rear sides of the top of the working floating frame 1 are respectively installed with operating rods 10 through hinges. In this way, the suction pump 504 is started to generate negative pressure inside the water pipe 502 and the sampling head 501, and the wastewater is pumped into the receiving frame head 903. When the sucked wastewater is in the receiving frame head 903, When accumulation forms, it will contact the bottom of the detection terminal 12, and detect the received wastewater through the detection instrument 11, and then transmit the detected data to the external control center through wireless transmission. After the wastewater detection is completed, the absorption solenoid valve 902 on the left is opened, and the wastewater inside the receiving frame head 903 is absorbed by the dry adsorption sponge 901. When there is no accumulated liquid inside the receiving frame head 903, sampling and detection can be carried out again, increasing the use time of sampling and detection, and sampling and detection can be carried out multiple times. When liquid water is injected into the receiving frame head 903, the movable floating ring 905 and the cleaning brush 906 will float up. When the liquid water is sucked away, the movable floating ring 905 and the cleaning brush 906 will fall, and the cleaning brush 906 will rub against the bottom of the outside of the detection terminal 12 to avoid accumulation of liquid on the outside of the detection terminal 12, which causes inaccurate detection.

[0048] Working principle: When the present invention detects wastewater in a water area, since the impurities contained in the wastewater are different, it is necessary to sample wastewater at different depths. When sampling, solid objects are added to the placement cavity 506 to increase the weight of the sampling head 501, and the small electric push rod 703 is started to drive the movable extrusion plate 701 to move backward, separate from the bottom end of the water pipe 502 so that the water pipe 502 loses its restraint, and the weight of the sampling head 501 drives the bottom end of the water pipe 502 to move downward, so that the water pipe 502 is tightened outside the rotating roller 503, and at the same time The movable slider 602 is driven to move to the right side of the movable slider 601 and the reset spring 604 is squeezed. Later, the reset spring 604 after squeezing drives the movable slider 602 to reset. When the movable slider 602 moves to the right, it contacts the sensor switch 605 on the left, and the small electric push rod 703 is started to drive the movable squeeze plate 701 to move forward and contact and squeeze the water pipe 502, and fix the water pipe 502. By triggering the sensor switches 605 at different positions, the downward position of the sampling head 501 can be determined. When the sampling is completed and recycled, it is started again. The suction pump 504 and the double-headed electromagnetic valve deliver gas to the water pipe 502 and the double-headed electromagnetic valve through the reverse rotation of the suction pump 504, and deliver the gas to the folded airbag 507, so that the folded airbag 507 expands and pushes down the solid objects filled in the placement cavity 506, and pushes the movable baffle 505 to discharge the filled solid objects, so that the sampling head 501 loses weight and the restraining force to move downward. The water pipe 502 and the sampling head 501 can be quickly adjusted by the buoyancy of the sampling head 501 itself and the driving force of the rebound of the reset spring 604. Recycling can be performed to increase the sampling and testing of wastewater at different depths, thereby increasing the comprehensiveness and accuracy of the testing process, and avoiding the situation where only the surface of the water can be sampled and tested, while underwater water with heavy particulate impurities cannot be sampled and tested, resulting in inaccurate final test results and errors. Further testing is required later, increasing the time and cost of testing, as well as the ability to protect the testing end during sampling and testing, to avoid the testing end extending underwater, resulting in water leakage, short circuits, and damage caused by impact and entanglement of underwater foreign objects;

[0049] Start the suction pump 504 to generate negative pressure inside the water pipe 502 and the sampling head 501, and pump the wastewater into the receiving frame head 903. When the sucked wastewater accumulates inside the receiving frame head 903, it will contact the bottom of the detection terminal 12, and the received wastewater will be detected by the detection instrument 11, and then the detected data will be transmitted to the external control center by wireless transmission. When the wastewater detection is completed, open the absorption solenoid valve 902 on the left side, and the wastewater inside the receiving frame head 903 will be sucked out by the dry adsorption sponge 901. When the liquid water is absorbed, when there is no liquid accumulation inside the receiving frame head 903, sampling and testing can be performed again, which increases the use time of sampling and testing, and sampling and testing can be performed multiple times. When liquid water is injected into the receiving frame head 903, the movable floating ring 905 and the cleaning brush 906 will float up. When the liquid water is absorbed, the movable floating ring 905 and the cleaning brush 906 will fall, and the cleaning brush 906 will rub against the bottom of the outside of the detection terminal 12 to avoid the adhesion of liquid accumulation on the outside of the detection terminal 12, which will cause inaccurate detection.

[0050] When testing the wastewater area of ​​the river environment, the hook 406 is taken out from the fixed frame head 3, and the hook 406 is thrown to the other side of the river for fixing, and the telescopic plug rod 402 is inserted into the river bank, and then the working floating frame 1 is placed on the river, and the single-phase motor 805 is started to drive the transmission wheel 801 at the bottom to rotate through the connecting rotating rod 806, and the transmission wheel 801 at the top is driven to rotate through the transmission belt 802, and the docking round block 811 at the upper end is driven to rotate, and the small electric telescopic rod 803 is started to drive the mounting frame rod 804 to move to the right side, which drives the top movable top rod 810 and the movable turntable 807 to move to the right side, so that the rectangular limit block 808 is engaged with the rectangular docking interface opened on one side of the docking round block 811, which will drive the movable turntable 807, the movable top rod 810 and the rotating rod 405 to rotate, and drive the transmission bevel gear 404 to rotate. The two transmission bevel gears 404 are meshed with each other, which will drive the rotating circular wheel 403 to rotate, causing the rotating circular wheel 403 to rub against the outside of the fixed positioning rope 401. When the mounting frame rod 804 moves to the right, it will drive the movable top rod 810 and the movable turntable 807 at the bottom to move to the right, so that the rectangular limit block 808 at the bottom and the inner part of the rectangular docking interface at the bottom are separated, so that the collecting roller 207 will not be rotated, and the working floating frame 1 and the fixed frame head 3 can be moved on the water surface, and various positions on the upper end of the river water surface can be detected, thereby increasing the range of river water surface sampling detection, and increasing the stability during mobile sampling detection, avoiding the situation that only one of the river water areas can be detected during the detection process, increasing the limitations of river detection, and failing to conduct a comprehensive detection of the river water area, resulting in errors between the final detection result and the actual situation.
