[0021] The rotating groove 102 is located between the first slide groove 103 and the second slide groove 110. The inner wall of the second slide groove 110 is fixedly connected with a support rod 105. A plurality of bristles 108 are fixedly connected to the second brush 109. The size of the float 107 is adapted to the size of the groove 104. The groove 104 and the float 107 are clamped together. The cross-section of the bristles 108 on the first brush 106 increases from left to right, and the cross-section of the bristles 108 on the second brush 109 decreases from left to right. The first slide groove 103 and the second brush 109 are directed upward from left to right. The material of the float 107 is plastic material. A plurality of bristles 108 respectively penetrate the inner walls of the first slide groove 103 and the second slide groove 110 and extend to the interior of the rotating groove 102.

[0022] The sensor mechanism 2 includes a rotating shaft 202, and propellers 201 are fixedly connected on both sides of the rotating shaft 202. A dissolved oxygen sensor 203, an ammonia nitrogen sensor 204, a pH sensor 205 and a nitrite sensor 206 are fixedly connected to the rotating shaft 202.

[0023] The above scheme is adopted: by setting the coordination of structures such as bristles 108 and propeller 201, it is convenient to clean the sensor.

After the water flows into the guide tube 301, it will enter the rotating groove 102 from the water inlet 306. The water flow will push the bristles 108 to move. When the water flows into the rotating groove 102 from left to right, it will push the bristles 108 on the second brush 109 and drive the second brush 109 to slide to the right in the second slide groove 110, so that the bristles 108 on the second brush 109 contact with the sensor to clean the sensor. When the water flows into the rotating groove 102 from right to left, it will push the bristles 108 on the first brush 106, so that the first brush 10 6 slides left, so that the bristles 108 on the first brush 106 contact the sensor to clean the sensor; at the same time, after the water flows into the acceleration cylinder 302, it will move along the direction of the thread groove 303, and as the pitch and diameter of the thread groove 303 decrease, the water flow will accelerate, and finally flow to the propeller 201, driving the propeller 201 to rotate along the direction of the thread groove 303. The rotation of the propeller 201 will drive the sensor to rotate through the rotating shaft 202, so that the rotating sensor is fully cleaned by the bristles 108, and the dirt and algae attached to the surface of the sensor are removed to avoid affecting the sensitivity and accuracy of the sensor, thereby ensuring the authenticity and reliability of the water quality monitoring data, thereby indirectly improving the timeliness and accuracy of the early warning, and reducing the erosion of the sensor by corrosive substances, reducing the failure rate, extending the service life, and reducing the maintenance and replacement costs.

[0024] like Figure 2 and Figure 3As shown, the guide mechanism 3 includes a guide tube 301, an acceleration tube 302 is arranged inside the guide tube 301, a threaded groove 303 is provided on the inner wall of the acceleration tube 302, a connecting frame 305 is fixedly connected to the side of the guide tube 301, a pyramid 304 is fixedly connected to the center of the connecting frame 305, a water inlet 306 is provided on the side of the guide tube 301 away from the connecting frame 305, and a water inlet 307 is provided on the side of the acceleration tube 302 away from the connecting frame 305. The shapes of the guide tube 301 and the acceleration tube 302 are both conical, the size of the water inlet 307 is smaller than the size of the water inlet 306, and the pyramid 304 is located inside the acceleration tube 302.

[0025] The side of the guide tube 301 away from the connecting frame 305 is fixedly connected to the side of the cleaning tube 101, the side of the acceleration tube 302 away from the connecting frame 305 is fixedly connected to the bracket 111, the propeller 201 is rotatably connected to the inner wall of the acceleration tube 302, the size of the water inlet 307 is adapted to the size of the propeller 201, the size of the water inlet 306 is larger than the size of the rotating groove 102, the size of the water inlet 307 is smaller than the size of the rotating groove 102, and the forward direction of the threaded groove 303 is consistent with the rotation direction of the propeller 201.

[0026] The main body mechanism 4 includes a connecting rod 401 , the top of the connecting rod 401 is fixedly connected to a buoy body 402 , the top of the buoy body 402 is fixedly connected to a signal alarm 403 , and the lower end of the connecting rod 401 is fixedly connected to the cleaning cylinder 101 .

[0027] like Figures 2 to 5 As shown, a smart fishery water quality monitoring and early warning system includes the following contents: Monitoring module: through the dissolved oxygen sensor 203, the ammonia nitrogen sensor 204, the pH value sensor 205 and the nitrite sensor 206, the dissolved oxygen content, the ammonia nitrogen content, the nitrite content and the pH value of the water quality are monitored in real time, and the data collected by the sensors are transmitted to the central system to provide basic data for the early warning system; Early warning module: When the cloud platform finds anomalies in the parameter data collected by the sensor, it will immediately trigger the early warning mechanism, start the signal alarm 403 to light up the internal warning light, and notify the fishery manager via phone and text message, reminding the fishery manager to take timely measures.

[0028] The above scheme is adopted: the bristles 108 are driven by water flow to contact the sensor to clean the sensor, and after the water flows into the acceleration cylinder 302, it moves along the direction of the thread groove 303. As the pitch and diameter of the thread groove 303 decrease, the water flow will accelerate and finally flow out of the propeller 201, driving the propeller 201 to rotate along the direction of the thread groove 303. The rotation of the propeller 201 will drive the sensor to rotate through the rotating shaft 202, so that the rotating sensor is fully cleaned by the bristles 108. No power support is required, and it is completely driven by water flow, which greatly reduces energy consumption and achieves environmental protection and energy saving. In addition, since there is no complex motor system, the structure is simpler, the maintenance cost is low, and the economy is better for long-term operation. The use of electronic components is reduced, the failure rate is reduced, and the overall stability of the system is enhanced. At the same time, wear can be reduced, the service life is extended, and safety hazards such as electrical short circuit and electric shock are eliminated.

[0029] The working principle and use process of the present invention are as follows: first, the fishery manager needs to place the device in the fishery so that the cleaning cylinder 101 is immersed in water. At this time, the water in the fishery will enter the interior of the rotating tank 102 through the water inlet 306 and the water inlet 307. At this time, the dissolved oxygen sensor 203, the ammonia nitrogen sensor 204, the pH sensor 205 and the nitrite sensor 206 located on the rotating shaft 202 of the rotating tank 102 will monitor the dissolved oxygen content, ammonia nitrogen content, nitrite content and pH value of the water quality through the sensitive element 207 in real time, and transmit the data collected by the sensor to the central system to provide basic data for the early warning system. When the cloud platform finds an abnormality in the parameter data collected by the sensor, it will immediately trigger the early warning mechanism, start the signal alarm 403 to light up the warning light inside it, and notify the fishery manager by phone and text message to remind the fishery manager to take timely measures; When the fishing ground is calm, the interior of the cleaning tube 101 will be in a state as follows: Figure 3In the state shown, the first brush 106 is at the upper right position of the rotating groove 102 under the buoyancy of the float 107, and the second brush 109 is at the lower left position of the second slide groove 110 under the action of gravity. At this time, the bristles 108 on the first brush 106 and the second brush 109 are separated from the sensor. When the wind blows on the fishing ground, the wind will drive the water in the fishing ground to flow, and part of it will flow into the inside of the guide tube 301 and the acceleration tube 302 respectively. After entering the guide tube 301, the water will enter the rotating groove 102 from the water inlet 306. The water flow will push The bristles 108 move. When the water flows into the rotating groove 102 from left to right, the bristles 108 on the second brush 109 are pushed, and the second brush 109 is driven to slide rightward in the second slide groove 110, so that the bristles 108 on the second brush 109 contact the sensor to clean the sensor. When the water flows into the rotating groove 102 from right to left, the bristles 108 on the first brush 106 are pushed, so that the first brush 106 slides leftward, so that the bristles 108 on the first brush 106 contact the sensor to clean the sensor. At the same time, after the water flows into the acceleration cylinder 302, it will move along the direction of the thread groove 303. As the pitch and diameter of the thread groove 303 decrease, the water flow will accelerate and finally flow to the propeller 201, driving the propeller 201 to rotate along the direction of the thread groove 303. The rotation of the propeller 201 will drive the sensor to rotate through the rotating shaft 202, so that the rotating sensor is fully cleaned by the bristles 108. Then the water flow will pass through the gap between the blades on the propeller 201 and be discharged into the rotating groove 102 from the water inlet 307, thereby accelerating the water speed inside the rotating groove 102 and taking away the pollutants inside the rotating groove 102.
