[0002] When preventing and controlling water pollution, it is necessary to monitor the changes in pollutant concentrations in the water in real time. Therefore, it is necessary to use water pollutant attenuation monitoring devices to promptly detect and warn of potential pollution incidents, which will help relevant departments take quick measures to prevent the spread of pollution.

[0003] The structure of the existing water pollutant attenuation monitoring device is relatively simple. When monitoring the river water, the water pollutant attenuation monitoring device mostly uses the potential energy of the river water flow to generate electricity. As time goes by, moss and garbage will adhere to the side walls of the blades when they are working. If they are not cleaned in time, the blades will get stuck. At the same time, the equipment will monitor the water flow at all times. When the gate is closed and the river water remains relatively still, it will not stop monitoring the water flow, which affects the service life of the equipment.

[0033] Embodiment 1

[0034] The staff installs the equipment on the dam wall through the slide rail 3. The cooperation between the buoy 2 and the slide rail 3 makes the equipment always float on the water surface. When the river water is flowing, the water flow hits the surface of the rotating blade 42, and the rotating blade 42 drives the rotating round rod 40 to rotate. When the rotating round rod 40 rotates, it drives the generator set 47 to work. The potential energy generated by the river flow is converted into electronic storage. When the rotating blade 42 rotates, the centrifugal force drives the annular cleaning brush 46 to move on the surface of the rotating blade 42. The first reset spring 44 elastically drives the annular cleaning brush 46 to reset, so that the annular cleaning brush 46 reciprocates on the surface of the rotating blade 42 to brush the side wall of the rotating blade 42, so as to prevent impurities and garbage in the water from adhering to the surface of the rotating blade 42, and the staff does not need to clean it. At the same time, the setting of the first telescopic rod 45 prevents the annular cleaning brush 46 from moving out of the surface of the rotating blade 42.

[0035] Embodiment 2

[0036] When the river water flows, the rotating rod 40 drives the transmission rod 53 to rotate through the first gear 50, the belt 51 and the second gear 52. The setting of the gearbox 41 can effectively reduce the rotation speed of the transmission rod 53. When the transmission rod 53 rotates to the bottom, the transmission rod 53 drives the sampling tube 55 to enter under the water surface through the rotating ring 54 and the fixed horizontal plate 56 to sample the water area. When the transmission rod 53 rotates to the top, the transmission rod 53 drives the sampling tube 55 to rise through the rotating ring 54 and the fixed horizontal plate 56 to complete the sampling of the water area. When the sampling tube 55 rises, it drives the drainage pipe 551 to rise, and the drainage pipe 551 drives the sliding sealing plate 612 upward The drain pipe 551 is connected with the water inlet pipe 64 by the lifting, and the water source inside the sampling tube 55 drives the sealing circular plate 59 to be pressed down by gravity. When the sealing circular plate 59 slides to the bottom of the drain pipe 551, the sampled water enters the sample storage tube 67 through the drain pipe 551 and the water inlet pipe 64. After the water source inside the sampling tube 55 is discharged, the sealing circular plate 59 is driven to reset to the top of the drain pipe 551 by the second reset spring 58 and the second telescopic rod 57. When the sampling tube 55 is away from the detection box 60, the third reset spring 611 elastically drives the sliding sealing plate 612 to reset and seal the water inlet pipe 64 to prevent river water from entering the detection box 60 at will.

[0037] Embodiment 3

[0038] During operation, after the sampled river water enters the sample storage tube 67 through the water inlet pipe 64, the sampled river water in the sample storage tube 67 is collected and then the sample storage tube 67 is pressed down by gravity until the trigger switch 69 is triggered. The trigger switch 69 controls the annular slide rail 65 to start, and the annular slide rail 65 drives the sample storage tube 67 to rotate through the sliding clamping cylinder 66. When the sampled river water in the sample storage tube 67 moves to the bottom of the water pollution detection sensor 631, the electric push rod 63 is started, and the electric push rod 63 drives the water pollution detection sensor The device 631 enters the sample storage tube 67 to detect water pollution. When the annular slide rail 65 drives the sample storage tube 67 to continue to move to the inside of the electric telescopic tube 622, the electric telescopic tube 622 is started to enter the sample storage tube 67, and the water pump 62 is started. The water pump 62 draws out the water source in the sample storage tube 67 through the water pumping pipe 621 and the electric telescopic tube 622, and discharges it through the outlet pipe 623, so that there is always an empty sample storage tube 67 in the detection box 60 to collect the sampled river water, thereby improving the degree of automation of the device.

[0039] Through the above steps, when the rotating round rod 40 rotates, the cooperation of the rotating blades 42, the first return spring 44 and the annular cleaning brush 46 can remove the garbage on the surface of the rotating blades 42, and prevent the garbage impurities from adhering to the surface of the annular cleaning brush 46 and causing it to get stuck and unable to work. At the same time, the potential energy of the river water flow can be converted into electricity through the setting of the rotating round rod 40, the rotating blades 42 and the generator set 47. At the same time, when the gate is closed, the river water remains relatively still, and the equipment will not sample the relatively still river water; this solves the problem that the monitoring device is prone to be attached with moss and garbage after long-term use, and is not cleaned in time, resulting in the blades getting stuck, affecting operation and reducing the service life of the equipment.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
