Description

Technical Field

[0001] The invention belongs to the field of water pollution source tracing, in particular to a water pollution source tracing device. Background Art

[0002] Wastewater can be classified in different ways from different perspectives. According to different sources, it can be divided into two categories: domestic wastewater and industrial wastewater; according to the chemical type of pollutants, it can be divided into inorganic wastewater and organic wastewater. The main pollutants are: (1) Untreated industrial wastewater; (2) Untreated domestic sewage; (3) Agricultural sewage caused by the large-scale use of fertilizers, pesticides, and herbicides; (4) Industrial waste and domestic garbage piled up by the river; (5) Deforestation and soil erosion; (6) Mine sewage generated due to over-exploitation.

[0003] The dissolved oxygen content in water. The higher the dissolved oxygen content, the better the water quality. If the dissolved oxygen content in water is low, it may indicate that there are certain pollutants or excessive organic matter in the water, such as sewage, wastewater, fertilizers, etc. These pollutants will consume oxygen and cause water hypoxia. In severe cases, it may cause eutrophication of water bodies, increased water toxicity and other problems.

[0004] Existing water pollution detection often traces the source through a step-by-step detection method, gradually moving from the polluted downstream to the upstream, moving towards the direction of the highest pollution concentration, and finally finding the source of pollution. This method requires sampling and testing at the riverside. Not only is the efficiency too low, but the operator also has to follow the polluted water source all the time, which also causes certain damage to the body. For some rivers that are inconvenient to pass, it also blocks the way forward.

[0005] To this end, the present invention provides a water pollution source tracing device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: a water pollution source tracing device described in the present invention comprises a suspension box, a flow box and a base, a central rod is rotatably connected through the middle of the flow box, and the upper and lower ends of the central rod are respectively fixed to the bottom of the suspension box and the top of the base, one end of the suspension box is provided with two through grooves, and the through grooves are connected with detection tubes, and the top of the suspension box is connected with two detectors, and the detection end of the detector is located in the middle of the detection tube, the outer side of the base is connected with a power tube, and the inner side of the power tube is provided with a propeller, and the outer side of the flow box is provided with a steering assembly, and the steering assembly is used to control the forward direction of the device;

[0008] Through the suspension box, the flow box and the base, the device is placed in the river along the upstream direction of the river. The propeller in the power tube provides power so that the device can go upstream. When going upstream, part of the water flow will pass through the detection tube, allowing the water flow to contact the detection end of the detector. Electromagnetic valves are provided at both ends of the detection tube, which can be closed after being filled with water. The detection end of the detector can be: a fluorescent dissolved oxygen sensor, which can detect the concentration of dissolved oxygen in the water and judge the water quality by the numerical value. As the equipment goes upstream, a threshold is set in the sensor. When the sewage value is detected to reach the threshold, it proves that the water quality here has been polluted seriously enough, even if it is not polluted. The real source of the pollution also needs to be treated, and this place must be not far from the source. The device is equipped with a wireless transmission module, which can transmit signals to the outside at this time. After the external terminal receives the signal, it locates the location and then recycles the equipment, thereby achieving the effect of finding the source of water pollution. It should be noted that in order to increase the probability of finding the source of pollution, the method of increasing the sample capacity and reducing accidental errors is used; that is, multiple devices are placed in the same location to increase the probability of finding the source of pollution; before the power is almost exhausted, the device will also release a wireless signal for staff to recycle. The signal transmission consumes low power and can last for 5-7 days to ensure that it can be found.

[0009] Preferably, the steering assembly includes an extension rope, which is connected to the flow box, and a float is fixedly connected to the end of the extension rope. Two side nozzles are connected to the outside of the base, and the two side nozzles are respectively located on both sides of the power tube. A detection module is provided in the base, and the detection module is used to detect the swing angle of the flow box. One end of the side nozzle located at the base is connected to a water pump. The rivers in the world are curved. In order to accurately go upstream, the float is set, and after the equipment enters the water, the top of the equipment sinks below the water surface. When the equipment moves forward, the two side nozzles continuously spray to both sides. , allowing the device to move forward steadily. At this time, it will not turn with the river, but will only move forward in the direction where it was originally placed. When the river turns upstream, due to the rotation connection of the flow box, the float moves backward with the flow of the river, so the straight line formed by the float and the extension rope will be parallel to the direction of the water flow. After the float changes direction with the river, it will pull the flow box to rotate together, so that the detection module can detect the rotation angle, and then it will control one of the side nozzles to increase the jet and change the direction of the device until the flow box is parallel to the power tube again, so that the entire device can always follow the direction of the river to go upstream.

[0010] Preferably, the detection module includes a detection seat, which is located on the inner side of the flow box, with one side of the detection seat facing the center rod, a laser emitting module is fixedly connected to the surface of the center rod, and a first receiving plate is fixedly connected to the side of the detection seat facing the center rod. When the flow box rotates, the laser emitted by the laser emitting module will move away from the first receiving plate, and then the forward direction of the base is adjusted through the side nozzle until the laser emitted by the laser emitting module is received by the first receiving plate again.

[0011] Preferably, the laser emitting module is arranged in a vertical long strip shape, and second receiving plates are fixedly connected to both sides of the first receiving plate. A mesh baffle is arranged on the outer side of the detection tube, and the baffle is arranged in an arc shape. When the flow box turns, the laser emitted by the laser emitting module will first move away from the first receiving plate, and then be received by one of the second receiving plates. The two second receiving plates represent two directions. In this way, it can be known to which angle the flow box is rotating, and the problem of wrong direction will not occur during the adjustment process. At the same time, the rotation of the flow box is limited, and the maximum rotation angle in one direction is ninety degrees.

[0012] Preferably, a storage box is fixedly connected to the inner side of the flow box, a driving motor is fixedly connected to the interior of the storage box, an output end of the driving motor is connected to a winding rod, and the outer side of the winding rod is fixedly connected to an extension rope. The river is formed by the confluence of numerous tributaries. In order to allow the device to move toward the tributary with the lowest dissolved oxygen content, the device will weaken the power of the power tube after moving forward for a period of time, allowing the device to temporarily hover. If the device enters the wrong tributary at this time, the power tube is closed to allow the device to flow down with the flow. At this time, the two side nozzles are not closed to ensure that the head of the device is still facing the original direction. After following the flow for a period of time, test again. If the concentration of solvent oxygen is high and exceeds the average concentration along the way, it means that it has entered the wrong branch. At this time, let the equipment go downstream again until it returns to the front of the tributary. At this time, because the concentration meets the standard, the equipment moves forward. Although it may still enter the wrong tributary at this time, it only needs to be repeated several times before it can enter the contaminated tributary. In this process, the drive motor rotates to wrap the extension rope so that the float is close to the flow box. Because the float is easy to be entangled on the equipment when following the flow, the extension rope will be released when the equipment is upstream.

[0013] Preferably, the interior of the suspension box is hollow, the outside of the suspension box is connected to a transmission pump, and both sides of the suspension box are connected to the base with a connecting frame. Through the setting of the transmission pump, water can be filled into the suspension box, or the water inside can be released, so that the equipment can float and sink.

[0014] Preferably, the base is made of solid material, the bottom of the base is ellipsoidal, a top column is fixedly connected to one end of the base away from the power tube, and the end of the top column is spherical. The setting of the base allows the center of gravity of the entire device to face downward and is not easy to flip over, while the setting of the top column can break the water flow and assist the advancement of the equipment.

[0015] Preferably, two separation tubes are connected between the side nozzle and the water pump, and the water pump has two output ends, which are respectively connected to the two separation tubes. An adjusting component is provided above one of the separation tubes, and the adjusting component is used to adjust the output size of the separation tube. Since the float of the device is in a recovered state during the process of hovering and following the flow, the steering function is weakened. At this time, the steering effect of the steering component is assisted by the adjusting component, so that the device can always face downward in the hovering and following the flow state. At the same time, this function can also directly replace the steering component, so that the device can always face forward without relying on the action of the laser equipment.

[0016] Preferably, the adjusting component includes a plurality of downward pressure columns, the bottom of which is flat and slidably engaged with one of the separation tubes, a through hole and a group of small holes are provided on the surface of the downward pressure column, one group of small holes is located below the through hole, and a downward pressure component is provided on the top of the downward pressure column. Two water pumps are always turned on. When the downward pressure column is not squeezed, the sprayed water flow needs to pass through multiple groups of small holes, resulting in too much kinetic energy being consumed. As the downward pressure column is pressed down, the water flow from the water pump can directly pass through the through hole, increasing the flow rate. In this way, the spray rate of the two side nozzles can be adjusted, thereby achieving the effect of adjusting the direction of the equipment.

[0017] Preferably, the down-pressing assembly includes a pressing piece, which is located below the flow box, and a spring is connected between the outer side of the down-pressing column and the base, a reduction motor is fixedly connected between the two separation tubes, and an arc-shaped stripping piece is connected to the output end of the reduction motor, and the stripping piece is made of magnetic material, and the bottom of the down-pressing column is also made of magnetic material. When the float of the flow box is not parallel to the power tube and turns, the flow box rotates at this time, which will cause the pressing piece to squeeze the down-pressing column. As the down-pressing column sinks and is adsorbed and fitted with the stripping piece, the through hole will replace the small hole to increase the flow rate. As the turning angle of the flow box increases, the flow rate increases more, so that the side nozzle on the corresponding side increases the spraying speed, so that the effect of adjusting the equipment to return to the center can be achieved. When the pressing piece returns to between the two groups of down-pressing columns, the reduction motor will start, and the stripping piece will move outward. Under the action of the spring, the down-pressing column rebounds to its position, and then the stripping piece returns to its position, so that it can be reused.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. A water pollution source tracing device described in the present invention is placed in a river along the upstream direction of the river through a suspension box, a flow box and a base. The propeller in the power tube provides power so that the device can go upstream. When going upstream, part of the water flow will pass through the detection tube, allowing the water flow to contact the detection end of the detector. Electromagnetic valves are provided at both ends of the detection tube, which can be closed after being filled with water. The detection end of the detector can be: a fluorescent dissolved oxygen sensor, which can detect the concentration of dissolved oxygen in water and judge the water quality through numerical values. As the device goes upstream, it reaches the place with the lowest dissolved oxygen concentration, which is the source of pollution. After reaching it, the device can transmit signals to the outside, thereby achieving the effect of finding the source of water pollution.

[0020] 2. The water pollution source tracing device described in the present invention has a float setting. After the device enters the water, the top of the device sinks below the water surface. When the device moves forward, the two side nozzles continuously spray to both sides, so that the device can move forward stably. At this time, it will not follow the river to turn, but will only continue to move forward in the direction of the initial placement. When the river turns upstream, due to the rotation connection of the flow box, the float moves backward with the flow direction of the river, so the straight line formed by the float and the extension rope will be parallel to the water flow direction. After the float changes direction with the river, it will pull the flow box to rotate together, so that the detection module can detect the rotation angle, and then it will control one of the side nozzles separately to increase the jet flow and change the direction of the device until the flow box is parallel to the power tube again, so that the entire device can always follow the direction of the river to go upstream.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 4 As shown, a water pollution source tracing device according to an embodiment of the present invention comprises a suspension box 1, a flow box 2 and a base 3, a center rod 16 is rotatably connected through the middle of the flow box 2, and the upper and lower ends of the center rod 16 are respectively fixed to the bottom of the suspension box 1 and the top of the base 3, one end of the suspension box 1 is provided with two through grooves, and a detection tube 9 is connected to the through grooves, and two detectors 12 are connected to the top of the suspension box 1, and the detection end of the detector 12 is located in the middle of the detection tube 9, the outer side of the base 3 is connected with a power tube 6, and a propeller is arranged on the inner side of the power tube 6, and a steering assembly is arranged on the outer side of the flow box 2, and the steering assembly is used to control the forward direction of the device;

[0032] At work, the existing water pollution detection often traces the source through a step-by-step detection method, gradually moving from the polluted downstream to the upstream, moving towards the direction of the highest pollution concentration, and finally finding the source of pollution. This method requires sampling and testing at the riverside all the time, which is not only too inefficient, but also causes certain damage to the operator's body by following the polluted water source all the time. For some rivers that are inconvenient to pass through, it also blocks the way forward;

[0033] Through the suspension box 1, the flow box 2 and the base 3, the device is placed in the river along the upstream direction of the river, and the propeller in the power tube 6 provides power so that the device can go upstream. When going upstream, part of the water flow will pass through the detection tube 9, allowing the water flow to contact the detection end of the detector 12. Both ends of the detection tube 9 are provided with electromagnetic valves, which can be closed after being filled with water. The detection end of the detector 12 can be: a fluorescent dissolved oxygen sensor, which can detect the concentration of dissolved oxygen in the water and judge the water quality by the numerical value. As the device goes upstream, a threshold value is set in the sensor. When the sewage value is detected to reach the threshold value, it proves that the water quality here has been polluted seriously enough. Even if it is not the real source of pollution, it also needs to be treated, and this place must be not far from the source. The device is installed with a wireless transmission module, which can transmit signals to the outside. After the external terminal receives the signal, it locates the location and then recycles the equipment, thereby achieving the effect of finding the source of water pollution. It should be noted that in order to increase the probability of finding the source of pollution, the method of increasing the sample capacity and reducing accidental errors is used; that is, multiple devices are placed at the same location to increase the probability of finding the source of pollution; before the power is exhausted, the device will also release a wireless signal for staff to recycle. The signal transmission consumes low power and can last for 5-7 days to ensure that it can be found.

[0034] like Figures 1 to 4 As shown, the steering assembly includes an extension rope 4, which is connected to the flow box 2, and a float 5 is fixedly connected to the end of the extension rope 4. Two side nozzles 7 are connected to the outside of the base 3, and the two side nozzles 7 are respectively located on both sides of the power tube 6. A detection module is provided in the base 3, and the detection module is used to detect the swing angle of the flow box 2. One end of the side nozzle 7 located at the base 3 is connected to a water pump 25;

[0035] When working, rivers in the world are curved. In order to accurately go upstream, through the setting of the float 5, after the equipment enters the water, the top of the equipment sinks below the water surface. When the equipment moves forward, the two side nozzles 7 continuously spray to both sides, so that the device can move forward stably. At this time, it will not follow the river to turn, but will only move forward in the direction of the initial placement. When the river turns upstream, due to the rotation connection of the flow box 2, the float 5 moves backward with the flow direction of the river, so the straight line formed by the float 5 and the extension rope 4 will be parallel to the direction of the water flow. After the float 5 changes direction with the river, it will pull the flow box 2 to rotate together, so that the detection module can detect the rotation angle, and then it will control one of the side nozzles 7 separately to increase the jet and change the direction of the device until the flow box 2 is parallel to the power tube 6 again, so that the entire device can always follow the direction of the river to go upstream.

[0036] like Figures 1 to 6As shown, the detection module includes a detection seat 20, the detection seat 20 is located on the inner side of the flow box 2, one side of the detection seat 20 faces the central rod 16, the surface of the central rod 16 is fixedly connected to the laser emission module 19, and the side of the detection seat 20 facing the central rod 16 is fixedly connected to the first receiving plate 21;

[0037] During operation, when the flow box 2 rotates, the laser emitted by the laser emitting module 19 will move away from the first receiving plate 21, and then the forward direction of the base 3 will be adjusted through the side nozzle 7 until the laser emitted by the laser emitting module 19 is received by the first receiving plate 21 again.

[0038] like Figures 1 to 6 As shown, the laser emitting module 19 is arranged in a vertical strip shape, the second receiving plates 22 are fixedly connected to both sides of the first receiving plate 21, and a mesh baffle 10 is arranged on the outer side of the detection tube 9, and the baffle 10 is arranged in an arc shape;

[0039] During operation, when the follow-up box 2 turns, the laser emitted by the laser emitting module 19 will first move away from the first receiving plate 21, and then be received by one of the second receiving plates 22. The two second receiving plates 22 represent two directions. In this way, it is possible to know the angle to which the follow-up box 2 is rotating, and there will be no problem of wrong direction during the adjustment process. At the same time, the rotation of the follow-up box 2 is limited, and the maximum rotation angle in one direction is ninety degrees.

[0040] like Figures 1 to 7 As shown, a storage box is fixedly connected to the inner side of the flow box 2, a driving motor 17 is fixedly connected to the interior of the storage box, a winding rod 18 is connected to the output end of the driving motor 17, and the outer side of the winding rod 18 is fixedly connected to the extension rope 4;

[0041] During operation, the river is formed by the confluence of numerous tributaries. In order to allow the device to move toward the tributary with the lowest dissolved oxygen content, the device will reduce the power of the power tube 6 after moving forward for a period of time, allowing the device to temporarily hover. If the device enters the wrong tributary at this time, close the power tube 6 and let the device flow downstream. At this time, the two side nozzles 7 are not closed to ensure that the head of the device is still facing the original direction. After flowing for a period of time, it is tested again. If the concentration of solvent oxygen is high and exceeds the average concentration along the way, it means that the wrong branch has been entered. At this time, the device is allowed to flow downstream again until it returns to the point before entering the tributary. At this time, since the concentration meets the standard, the device moves forward. Although it may still enter the wrong tributary at this time, it only needs to be repeated several times to enter the polluted tributary. In this process, the drive motor 17 rotates to wrap the extension rope 4 around it, allowing the float 5 to be close to the flow box 2, because when flowing downstream, the float 5 is easily wrapped around the device. When the device is upstream, the extension rope 4 is released.

[0042] like Figures 1 to 6 As shown, it also includes an external charging box 28, which is used to place the device body. The outer surface of the external charging box 28 is provided with a solar panel for storing energy and charging the device body at the same time. The interior of the suspension box 1 is hollow, and a transmission pump 8 is connected to the outside of the suspension box 1. Both sides of the suspension box 1 are connected to the base 3 with a connecting frame 11. When working, through the setting of the transmission pump 8, water can be filled into the suspension box 1, or the water inside can be released, so that the device can float and sink.

[0043] like Figures 1 to 6 As shown, the base 3 is made of solid material, the bottom of the base 3 is ellipsoidal, one end of the base 3 away from the power tube 6 is fixedly connected with a top column 13, and the end of the top column 13 is spherical. When working, the base 3 is set so that the center of gravity of the whole device is downward, and it is not easy to overturn, and the setting of the top column 13 can break the water flow and assist the advancement of the equipment.

[0044] like Figures 1 to 6 As shown, two separation pipes 23 are connected between the side nozzle 7 and the water pump 25. The water pump 25 has two output ends, which are respectively connected to the two separation pipes 23. An adjustment component is arranged above one of the separation pipes 23, and the adjustment component is used to adjust the output size of the separation pipe 23.

[0045] During operation, since the float 5 is in a recovered state when the device is hovering and following the flow, the steering function is weakened. At this time, the steering effect of the steering component is assisted by the adjustment component, so that the device can always face downward when hovering and following the flow. At the same time, this function can also directly replace the steering component, so that the device can always face forward without relying on the action of the laser device.

[0046] like Figures 1 to 6 As shown, the adjustment assembly includes a plurality of lower pressure columns 14, the bottom of the lower pressure column 14 is flat, and the bottom of the lower pressure column 14 is slidably engaged with one of the separation tubes 23, a through hole 27 and a group of small holes are opened on the surface of the lower pressure column 14, and the group of small holes is located below the through hole 27, and a lower pressure assembly is arranged on the top of the lower pressure column 14;

[0047] During operation, the two water pumps 25 are always turned on. When the lower pressure column 14 is not squeezed, the sprayed water needs to pass through multiple groups of small holes, resulting in too much kinetic energy being consumed. As the lower pressure column 14 is pressed downward, the water flow of the water pump 25 can directly pass through the through hole 27, increasing the flow rate. In this way, the spray rate of the two side nozzles 7 can be adjusted, thereby achieving the effect of adjusting the direction of the equipment.

[0048] like Figures 1 to 6As shown, the pressing assembly includes a pressing piece 15, and the pressing piece 15 is located below the flow box 2. A spring is connected between the outer side of the pressing column 14 and the base 3. A reduction motor 26 is fixedly connected between the two separation tubes 23. The output end of the reduction motor 26 is connected to an arc-shaped stripping piece 24, and the stripping piece 24 is made of magnetic material. The bottom of the pressing column 14 is also made of magnetic material.

[0049] During operation, when the float 5 of the flow box 2 is not parallel to the power tube 6 and turns, the flow box 2 rotates, which will cause the pressing piece 15 to squeeze the lower pressure column 14. As the lower pressure column 14 sinks and is adsorbed and fitted with the stripping piece 24, the through hole 27 will replace the small hole to increase the flow rate. As the turning angle of the flow box 2 increases, the flow rate increases more, thereby increasing the spraying speed of the side nozzle 7 on the corresponding side, so that the effect of adjusting the equipment to return to the center position can be achieved. When the pressing piece 15 returns to between the two groups of lower pressure columns 14, the reduction motor 26 will start, and the stripping piece 24 will move outward. Under the action of the spring, the lower pressure column 14 rebounds to its position, and then the stripping piece 24 returns to its position, so that it can be reused.

[0050] When working, the device is placed in the river along the upstream direction of the river through the suspension box 1, the flow box 2 and the base 3. The propeller in the power tube 6 provides power so that the device can go upstream. When going upstream, part of the water flow will pass through the detection tube 9, allowing the water flow to contact the detection end of the detector 12. Electromagnetic valves are provided at both ends of the detection tube 9, which can be closed after being filled with water. The detection end of the detector 12 can be: a fluorescent dissolved oxygen sensor, which can detect the concentration of dissolved oxygen in the water and judge the water quality by the value. As the device goes upstream, a threshold is set in the sensor. When the sewage value is detected to reach the threshold, it proves that the water quality here has been polluted seriously enough. Even if it is not the real source of pollution, it still needs to be treated, and this place must be not far from the source. The device is equipped with a wireless transmission module, which can transmit signals to the outside. After the external terminal receives the signal, it locates the location and recycles the equipment, thereby achieving the effect of finding the source of water pollution. It should be noted that in order to increase the probability of finding the source of pollution, the method of increasing the sample capacity and reducing accidental errors is used; that is, multiple devices are placed at the same location to increase the probability of finding the source of pollution; before the power is exhausted, the device will also release a wireless signal for the staff to recycle. The signal transmission consumes low power and can last for 5-7 days to ensure that it can be found.

[0051] All rivers in the world are curved. In order to accurately go upstream, the float 5 is set. After the device enters the water, the top of the device sinks below the water surface. When the device moves forward, the two side nozzles 7 continuously spray to both sides, so that the device can move forward stably. At this time, it will not follow the river to turn, but will only move forward in the direction where it is placed at the beginning. When the river turns upstream, due to the rotation connection of the flow box 2, the float 5 moves backward with the flow direction of the river, so the straight line formed by the float 5 and the extension rope 4 will be parallel to the direction of the water flow. After the float 5 changes direction with the river, it will pull the flow box 2 to rotate together, so that the detection module can detect the rotation angle, and then it will control one of the side nozzles 7 to increase the jet flow and change the direction of the device until the flow box 2 is parallel to the power tube 6 again, so that the whole device can always follow the direction of the river to go upstream;

[0052] When the flow box 2 rotates, the laser emitted by the laser emitting module 19 will move away from the first receiving plate 21, and then the forward direction of the base 3 is adjusted through the side nozzle 7 until the laser emitted by the laser emitting module 19 is received by the first receiving plate 21 again;

[0053] When the flow box 2 turns, the laser emitted by the laser emitting module 19 will first move away from the first receiving plate 21, and then be received by one of the second receiving plates 22. The two second receiving plates 22 represent two directions. In this way, it is possible to know the angle to which the flow box 2 is rotating, and there will be no problem of wrong direction during the adjustment process. At the same time, the rotation of the flow box 2 is limited, and the maximum rotation angle in one direction is ninety degrees.

[0054] The river is formed by the confluence of many tributaries. In order to make the device move toward the tributary with the lowest dissolved oxygen content, the device will weaken the power of the power tube 6 after moving forward for a period of time, so that the device will temporarily hover. If the device enters the wrong tributary at this time, the power tube 6 will be closed to let the device flow downstream. At this time, the two side nozzles 7 will not be closed to ensure that the head of the device is still facing the original direction. After following the flow for a period of time, it will be tested again. If the concentration of solvent oxygen is high and exceeds the average concentration along the way, it means that the wrong branch has been entered. At this time, the device is allowed to flow downstream again until it returns to the point before entering the tributary. At this time, because the concentration meets the standard, the device moves forward. Although it may still enter the wrong tributary at this time, it only needs to be repeated several times to enter the polluted tributary. In this process, the drive motor 17 rotates to wrap the extension rope 4 so that the float 5 is close to the flow box 2, because when flowing downstream, the float 5 is easy to be wrapped around the device. When the device is upstream, the extension rope 4 is released;

[0055] By setting the transmission pump 8, water can be filled into the suspension tank 1, or the water inside can be released, so that the device can float up and sink;

[0056] The setting of the base 3 makes the center of gravity of the whole device face downward, which is not easy to flip over, and the setting of the top column 13 can break the water flow and assist the forward movement of the device;

[0057] Since the float 5 is in a retracted state when the device is hovering and following the flow downward, the steering function is weakened. At this time, the steering effect of the steering component is assisted by the adjustment component, so that the device can always face downward when hovering and following the flow. At the same time, this function can also directly replace the steering component, so that the device can always face forward without relying on the laser device.

[0058] The two water pumps 25 are always turned on. When the lower pressure column 14 is not squeezed, the sprayed water needs to pass through multiple groups of small holes, resulting in too much kinetic energy being consumed. As the lower pressure column 14 is pressed downward, the water flow of the water pump 25 can directly pass through the through hole 27, making the flow rate larger, so that the spraying speed of the two side nozzles 7 can be adjusted, thereby achieving the effect of adjusting the direction of the device;

[0059] When the float 5 of the flow box 2 is not parallel to the power tube 6 and turns, the flow box 2 rotates, which will cause the pressing piece 15 to squeeze the lower pressure column 14. As the lower pressure column 14 sinks and is adsorbed and fitted with the stripping sheet 24, the through hole 27 will replace the small hole to increase the flow rate. As the turning angle of the flow box 2 increases, the flow rate increases more, thereby increasing the spraying speed of the side nozzle 7 on the corresponding side. In this way, the effect of adjusting the equipment to return to the center position can be achieved. When the pressing piece 15 returns to between the two groups of lower pressure columns 14, the reduction motor 26 will start, and the stripping sheet 24 will move outward. Under the action of the spring, the lower pressure column 14 rebounds to its position, and then the stripping sheet 24 returns to its position, so that it can be reused.
