A water storage cylinder 9 is fixedly connected to the bottom of the rain collecting trough 1. A measuring cylinder 10 is fixedly connected to one side of the water storage cylinder 9. A glass cover 11 is fixedly embedded in the surface of the water storage cylinder 9. A drain valve 12 is fixedly connected to the surface of the water storage cylinder 9. A piston float 14 is slidably mounted inside the measuring cylinder 10. An infrared ray measuring device 15 is fixedly connected to the top of the measuring cylinder 10.

[0024] Furthermore, a filter plate 6 is mounted on the inner wall of the rainwater collecting trough 1, and a plurality of filter holes 7 are opened near the center of the surface of the filter plate 6;

[0025] During operation, a plurality of filter holes 7 are provided on the surface of the filter plate 6 near the center thereof, so that the filter plate 6 can filter and collect rainwater.

[0026] Furthermore, a clamping block 16 is fixedly connected to the interior of the measuring cylinder 10, and the inner side of the clamping block 16 is in contact with the surface of the piston floating plate 14;

[0027] During operation, the inner side of the clamping block 16 is in contact with the surface of the piston floating plate 14 , so that the clamping block 16 has a limiting effect on the piston floating plate 14 , thereby improving the stability of the piston floating plate 14 when it is raised or lowered.

[0028] Furthermore, the top of the drain valve 12 is fixedly connected to the output end of the motor 13, and the side of the motor 13 is fixedly connected to the surface of the water storage cylinder 9;

[0029] During operation, the output end of the motor 13 fixedly connected to the surface of the water storage cylinder 9 is fixedly connected to the drain valve 12 , which makes it easy to automatically control the opening and closing of the drain valve 12 through the motor 13 .

[0030] Furthermore, a filter screen 17 is fixedly connected to the interior of the water storage cylinder 9, and the outer surface of the filter screen 17 is connected to the interior of the measuring cylinder 10;

[0031] During operation, the filter screen 17 is fixedly connected to the interior of the water storage cylinder 9 and is connected to the interior of the measuring cylinder 10. The filter screen 17 filters the rainwater entering the measuring cylinder 10 again, reducing the possibility of clogging of the piston float 14.

[0034] Working principle: The rainwater collecting trough 1 is placed in a suitable working place through the support column 2 and the bottom plate 3. Rainwater falls into the rainwater collecting trough 1 and is initially filtered into the water storage cylinder 9 through the filter holes 7 on the surface of the filter plate 6. The bottom of the water storage cylinder 9 is connected with the bottom of the measuring cylinder 10, and the top is ventilated to form a communicating vessel structure. The rainwater entering the measuring cylinder 10 is filtered again by the filter mesh 17, which reduces the possibility of blockage of the piston float 14. The block 16 is attached to the side of the piston float 14 to improve the stability of the piston float 14 when it is raised and lowered. The infrared ray measuring device 15 irradiates the surface of the piston float 14 to measure the distance and calculate the rainfall per unit area. When the piston float 14 rises to a certain level, the infrared ray measuring device 15 sends a signal to control the external power supply to start the motor 13 and the drain valve 12 to discharge the rainwater. The glass cover 11 fixedly embedded on the surface of the water storage cylinder 9 facilitates workers to actually observe the amount of rainwater inside the water storage cylinder 9, thereby improving the diversity and accuracy of the detection results.

[0035] After the device has been working for a long time, a lot of debris may accumulate on the surface of the filter plate 6, affecting the collection of rainwater by the rain collecting trough 1. The scraper 5 is manually slid to clean the surface of the filter plate 6. The design of the slope 4 on the surface of the rain collecting trough 1 facilitates the discharge of debris that affects the normal collection of rainwater by the device.
