The middle cone wheel 2 is a conical structure with the lower part narrowing towards the center. The lower inclined scraping bars 201 are fixed on the lower inclined surface of the middle cone wheel 2. The top of the middle cone wheel 2 is rotatably connected to the upper conical frame 102. The water flow between the upper rain collection funnel 1 and the middle cone wheel 2 drives the middle cone wheel 2, the lower inclined scraping bars 201, the lower middle shaft 202, and the lower scraping frames 203 to rotate. The middle part of the upper tipping bucket 3 is rotatably connected to the water flow regulating tank 301. The water flow regulating tank 301 is fixedly connected to the middle part of the lower support column 104. The lower end outlet of the water flow regulating tank 301 is above a counting tipping bucket 302. The middle part of the counting tipping bucket 302 is rotatably connected to the lower base 105. The upper tipping bucket 3 is arranged below the upper rain collection funnel 1, and the upper tipping bucket 3 is below the lower end outlet of the upper rain collection funnel 1. The reed switch counting module 106 is on one side of the counting tipping bucket 302. Magnets at both ends of the counting tipping bucket 302 pass through the reed switch counting module 106 for counting operations. The number of flips of the counting tipping bucket 302 recorded by the reed switch counting module 106 is used to calculate the water flow passing through the counting tipping bucket 302.

[0031] In the embodiments of the present disclosure, the upper conical frame 102 has a structure that gradually narrows from bottom to top. The size of the upper conical frame 102 is larger than that of the middle cone wheel 2. There is a space between the upper conical frame 102 and the upper rain collection funnel 1. The upper drainage plate 103 is fixed on the upper inclined surface of the upper conical frame 102. The upper conical frame 102 guides the water flow to flow downward along the space between the upper rain collection funnel 1 and the middle cone wheel 2. The width between the upper rain collection funnel 1 and the middle cone wheel 2 is narrower. The inner drainage plate 101 and the upper drainage plate 103 guide the water flow to flow in a spiral manner, and the water flow forms a vortex water flow structure, which accelerates the flow rate of the water flow and takes away the excess sediment.

[0032] In the embodiments of the present disclosure, the lower inclined surface of the middle cone wheel 2 and the lower narrowing inclined surface of the upper rain collection funnel 1 are arranged at intervals. The lower inclined scraping strip 201 is in sliding fit with the lower narrowing inclined surface of the upper rain collection funnel 1. The lower scraping frame 203 is in fit with the inner wall of the lower end of the upper rain collection funnel 1. The water flow between the upper rain collection funnel 1 and the middle cone wheel 2 drives the middle cone wheel 2, the lower inclined scraping strip 201, the lower middle shaft 202 and the lower scraping frame 203 to rotate. While the lower inclined scraping strip 201 and the lower scraping frame 203 are rotating, they are in sliding fit with the inner side of the upper rain collection funnel 1. The lower inclined scraping strip 201 and the lower scraping frame 203 clean the attachments such as moss on the inner side of the upper rain collection funnel 1, keep the inside of the upper rain collection funnel 1 clean, and extend the cleaning and maintenance interval period of the upper rain collection funnel 1.

[0033] In Embodiment 2, on the basis of Embodiment 1, a cover plate is arranged at the bottom of the upper rain collection funnel 1 through the main shaft of the motor. On sunny days, the cover plate covers the top entrance of the upper rain collection funnel 1 to prevent external sand and leaves from entering the inside of the upper rain collection funnel 1 and reduce the accumulation of sediment inside the upper rain collection funnel 1. On rainy days, the main shaft of the motor rotates to drive the cover plate to rotate to the outside, and the top entrance of the upper rain collection funnel 1 collects rainwater.

[0034] The working principle of this embodiment: The top opening of the upper rain collection funnel 1 introduces precipitation. The precipitation enters the inside of the upper rain collection funnel 1. The upper conical frame 102 guides the water flow to flow downward along the space between the upper rain collection funnel 1 and the middle cone wheel 2. The width between the upper rain collection funnel 1 and the middle cone wheel 2 is narrower. The inner drainage plate 101 and the upper drainage plate 103 guide the water flow to flow in a spiral manner, and the water flow forms a vortex water flow structure, which accelerates the flow rate of the water flow, takes away the sediment in the water, reduces the sediment deposition in the water flow, and the faster water flow can also wash the dust inside the upper rain collection funnel 1; The water flow between the upper rain collection funnel 1 and the middle cone wheel 2 drives the middle cone wheel 2, the lower inclined scraping strip 201, the lower middle shaft 202 and the lower scraping frame 203 to rotate. While the lower inclined scraping strip 201 and the lower scraping frame 203 are rotating, they are in sliding fit with the inner side of the upper rain collection funnel 1. The lower inclined scraping strip 201 and the lower scraping frame 203 clean the attachments such as moss on the inner side of the upper rain collection funnel 1, keep the inside of the upper rain collection funnel 1 clean, extend the cleaning and maintenance period of the upper rain collection funnel 1, extend the interval time of manual cleaning by personnel, and reduce the maintenance burden of personnel;

[0035] The water flow of the upper rain collection funnel 1 flows out from the lower end to the upper tipping bucket 3. When there is no water in the upper tipping bucket 3, it will also tilt to one side. The two sides of the upper tipping bucket 3 are partitioned into two parts by a middle partition board. The raised end of the upper tipping bucket 3 will receive the flowing water from the upper rain collection funnel 1. After the water flow on one side of the upper tipping bucket 3 increases, it will move downward, and the other side of the upper tipping bucket 3 will tilt up and move under the upper rain collection funnel 1 to collect rainwater. The upper tipping bucket 3 diverts the water flow into the throttling water tank 301, and the lower end of the throttling water tank 301 then diverts the rainwater into the counting tipping bucket 302. The structure and working mode of the counting tipping bucket 302 are the same as those of the upper tipping bucket 3. The magnets at both ends of the counting tipping bucket 302 perform counting operations through the reed switch counting module 106. The reed switch counting module 106 records the number of flips of the counting tipping bucket 302 and records the amount of water inside the counting tipping bucket 302 to measure the precipitation.
