[0002] The multi-sensing double-bucket rain gauge is an instrument used to measure precipitation. It is widely used in meteorological monitoring, agricultural irrigation, urban drainage management, water resources management and other fields.

[0015] Working principle: first place the support platform 201 in an open area, and use the adjusting bolt 204 to fix the entire device on the ground. At the same time, pay attention to the state of the level bubble 202 during the rotation of the adjusting bolt 204 to ensure that the bubble in the level bubble 202 is in the center position. At this time, place the shell 101 on the support platform 201, and use the cleaning and disassembly nut 107 to fix the filter screen 106, and fix the shell 101 with the support platform 201 through the fixing bolt 102. When the equipment is working, rainwater is first collected by the water receiver 103, and the impurities in the rainwater are filtered by the filter screen 106 in the water receiver 103. After the filtration is completed, the rainwater enters the first measuring device 3 through the collecting funnel 104, and the rainwater gradually drips on one side of the first tipping bucket 305 through the bottom of the collecting funnel 104. When the rainwater precipitation on one side of the first tipping bucket 305 reaches 0.1mm, the first tipping bucket 305 flips over and the first tipping bucket 30 5 is discharged into the collecting funnel 306 through the first counting bucket 308. At this time, the first bucket 305 starts to collect water on the other side, and the above operation is repeated. At the same time, when the first bucket 305 is turned over, the first magnet 309 rotates accordingly. Since the first magnet 309 and the first reed switch 304 are adapted to each other, the first reed switch 304 will be closed once and transmit a signal once through the first terminal 303. Finally, the rainwater collected in the collecting funnel 306 falls into one side of the second counting bucket 405. When the rainfall on one side of the second counting bucket 405 reaches 0.5 mm, the second counting bucket 405 is turned over, and the rainwater in the second counting bucket 405 is discharged through the drainage shell 406. The above operation is repeated, and the rotation of the second magnet 407 at the rear end of the second counting bucket 405 is used to control the closing technology of the second reed switch 401. Finally, the closing technology of the first reed switch 304 and the second reed switch 401 is used to calculate the actual rainfall.

[0016] (III) Beneficial effects

[0017] The present invention provides a multi-sensitivity double-tipping bucket rain sensor. It has the following beneficial effects:

[0018] 1. By setting up a supporting device, the supporting platform is placed in an open area, and the device is fixed to the ground with adjusting bolts. At the same time, pay attention to the state of the level bubble during the rotation of the adjusting bolts to ensure that the bubble in the level bubble is in the center position, effectively ensuring that the device as a whole is in an absolutely horizontal state before testing to avoid affecting the accuracy of the experimental results.

[0019] 2. By setting up a collection device, the shell is placed on the support table, the filter is fixedly connected by a cleaning and disassembly nut, and the shell is fixed to the support table by fixing bolts. When the equipment is working, rainwater is first collected by the water receiver, and the impurities in the rainwater are filtered by the filter in the water receiver. After the filtration is completed, the rainwater enters the first measuring device through the collecting funnel. By setting a filter in the water receiver and fixing the filter with a cleaning and disassembly nut, the filter can be removed to avoid clogging of the equipment caused by long-term use of the water receiver.

[0020] By setting the first measuring device, rainwater gradually drips on one side of the first bucket through the bottom of the collecting funnel. When the rainwater precipitation on one side of the first bucket reaches 0.1mm, the first bucket flips over, and the rainwater in the first bucket is discharged into the counting bucket through the water receiving shell. A small magnet is installed in the middle of the counting bucket, and a reed switch is installed on the magnet. When the counting bucket flips over once, the switch is closed once, and a signal is sent due to the closure of the switch. The output signal is led out by the red and black terminals. Then the other side of the first bucket starts to collect water, and the above operation is repeated. The rainfall is preliminarily counted and calculated by using the flip count of the first counting bucket. Statistics and calculation can be performed when the rainfall is small. At the same time, the first measuring device can also play a good buffering role for rainwater.

[0021] 3. By providing a second measuring device, the rainwater collected in the funnel finally falls into one side of the second counting bucket. When the rainfall on one side of the second counting bucket reaches 0.5 mm, the second counting bucket flips over and discharges the rainwater in the second counting bucket through the drainage shell. Repeat the above operation, and use the rotation of the second magnet at the rear end of the second counting bucket to control the closing technology of the second reed switch. Finally, use the closing technology of the first reed switch and the second reed switch to calculate the actual rainfall. Combined with the first measuring device, the rainfall in the area is further calculated, and it can be used when the rainfall is large, which will not increase the error of the monitoring result, effectively improve the measurement accuracy and resolution, and increase the scope of application of the device.
