[0033] Working principle: When in use, place the device in the designated position and level it, and then fix it by inserting bolts into the bolt holes 104 and the base surface in the designated position; When leaves and other debris fall, the isolation net 204 isolates them, preventing them from falling into the device. During active cleaning, the ring motor 201 is activated, driving the transmission cylinder 206 to rotate the centrifugal rotating frame 203 and the isolation net 204. When the centrifugal rotating frame 203 and the isolation net 204 rotate, the leaves and other debris on their surfaces are centrifugally thrown away from the axis. At the same time, the rotation of the transmission cylinder 206 drives the internal cleaning fan blades 202 to rotate. The rotation of the cleaning fan blades 202 pushes the airflow, allowing the airflow to pass through the air intake channel 110 and enter the air intake ring 107. Then, it is accelerated by the cleaning fan blades 202 and blown upward. The upward airflow pushes the leaves and other debris on the surface of the isolation net 204. The thrust of the airflow combined with the centrifugal effect cleans the leaves and other debris from the surface of the centrifugal rotating frame 203 and the isolation net 204, thereby ensuring the stability of the effective rain-bearing area of ​​the isolation net 204. When it rains, most of the rainwater passes through the isolation net 204 and falls into the device. A small amount of rainwater blocked by the isolation net 204 will also be introduced into the device due to the settling of the annular groove 205. Then the rainwater is introduced into the transmission cylinder 206 along the guide cone surface 209, and then from the transmission cylinder 206 into the tipping bucket 301. When the rainwater inside the upper tipping bucket 301 accumulates to a certain capacity, the gravity of the rainwater will overcome the tension of the tension spring 403 and the bias of the upper tipping bucket 301, causing the water-accumulating side of the upper tipping bucket 301 to tip over. At the same time, the tension spring 403 next to the upper tipping bucket 301 rebounds after passing its extreme point, and the other side of the upper tipping bucket 301 continues to accumulate water. The tipped-over rainwater flows into the lower tipping bucket 303 along the guide funnel 302. When the rainwater inside the lower tipping bucket 303 accumulates to a certain capacity, the gravity of the rainwater will overcome the tension of the tension spring 403 and the bias of the lower tipping bucket 303, causing the water-accumulating side of the lower tipping bucket 303 to tip over. At the same time, the tension spring 403 next to the lower tipping bucket 303 rebounds after passing its extreme point, and the other side of the lower tipping bucket 303 continues to accumulate water. When the water on the other side of the upper tipping bucket 301 accumulates to a certain volume, it will repeat the original action, causing the bucket on the side with new water to tip over, which in turn causes the lower tipping bucket 303 to repeat the tipping action. Each time the lower tipping bucket 303 tip over, the trigger magnet 316 and the reed switch 318 on one side will approach each other once. The reed switch 318 will feed back the electrical signal triggered when it approaches through the circuit. The greater the rainwater flow, the faster the water accumulation rate of the upper tipping bucket 301 and the lower tipping bucket 303, the faster the tipping frequency, and the faster the trigger magnet 316 triggers the reed switch 318. Therefore, by calculating the frequency of the electrical signal, the rainwater flow can be obtained. The electronic thermometer 111 can convert the temperature signal into an electrical signal and feed it back through the circuit, thereby realizing the detection of rainfall and temperature and the forecast of subsequent rainfall.
