[0027] The bottom end of the precipitation collection cylinder 1 is fixedly connected with a fixed base 5, a plurality of threaded fixing holes 6 in a circumferential array are formed in the fixed base 5, and a fixing bolt 7 is threadedly connected in each threaded fixing hole 6. Through the arrangement of the fixed base 5, the threaded fixing holes 6 and the fixing bolts 7, the fixing base 5 can be fixedly installed at a suitable position by the fixing bolts 7, so that the precipitation collection cylinder 1 can be stably supported, and the device and the electrical elements inside the device can be kept stable operation.
[0028] Please refer to Figure 1 , the outer surface of the precipitation collection cylinder 1 is hingedly connected with a hinged door 11, a handle is installed on the surface of the hinged door 11, so that the hinged door 11 can be opened by the handle, and the measuring tank 2 inside the precipitation collection cylinder 1 can be taken out or put into the precipitation collection cylinder 1, thereby improving the convenience of taking the measuring tank 2. The hinged door 11 and the precipitation collection cylinder 1 have a stable installation connection relationship, and the specific installation mode of the hinged door 11 is the prior art, which will not be described in detail in this application.
[0029] Please refer to Figure 2 and Figure 3 , the inside of the precipitation collection cylinder 1 is movably connected with a measuring tank 2, and a water level sensor 4 is fixedly installed on the outside of the measuring tank 2. The measuring tank 2 can receive precipitation such as rain, snow and hail, and the water level sensor 4 can measure the water level. The water level sensor 4 can measure the water level in the measuring tank 2 and transmit the measured value to the computer in the control room through wireless signal, so that the meteorological observer can detect the precipitation in real time.

The installation position in the drawings of this application is only for reference, and the specific production style is not described in detail.
[0030] Please refer to Figure 2 , Figure 3 and Figure 4 , the inside of the precipitation collection cylinder 1 is provided with a snow melting mechanism 3 for preventing snow from freezing, the snow melting mechanism 3 includes a fixed ring 301 fixed in the inside of the precipitation collection cylinder 1, and a water collecting cylinder 307 is fixedly connected to the bottom surface of the fixed ring 301. The water collecting cylinder 307 is matched with the measuring tank 2, and the bottom end opening of the water collecting cylinder 307 is smaller than the top surface opening of the measuring tank 2, so that the precipitation can flow into the measuring tank 2. The water collecting cylinder 307 can collect water, and the rain, snow and hail entering the inside of the precipitation collection cylinder 1 can be collected into the measuring tank 2, so that the precipitation can be completely measured in the measuring tank 2, and the loss of precipitation to other positions can be avoided to affect the accuracy of measurement. The precipitation collection cylinder 1 and the fixed ring 301 have good airtightness, so that the precipitation can not flow out of the measuring tank 2.
[0031] The upper part of the fixed ring 301 is provided with a filter plate 302, which is in sliding connection with the precipitation collection cylinder 1. The filter plate 302 can block and filter impurities, so that stones, leaves and other impurities cannot enter the measuring tank 2 through the precipitation collection cylinder 1, thereby affecting the accuracy of the device in measuring rainwater. The filter plate 302 can also prevent a large amount of snow from entering the measuring tank 2, so that the measuring tank 2 is not full. The low melting efficiency inside the measuring tank 2 can prevent excess snow from entering the measuring tank 2, thereby seriously affecting the measurement result of the device on the amount of precipitation.
[0032] The top surface of the fixed ring 301 is fixedly connected with a plurality of circumferentially arranged extension springs 303. The elastic potential energy of the extension springs 303 is sufficient to support the filter plate 302, and the extension springs 303 will deform as the gravity acting on the filter plate 302 increases. The shaking caused by the material properties of the extension springs 303 is within the acceptable range of the device and does not affect the normal use of the device.

A plurality of pressure sensors 304 are fixedly installed on the top surface of the fixed ring 301. When a large amount of snow enters the precipitation collection cylinder 1, the snow will accumulate on the filter plate 302 and block the filter plate 302. As the snow or hail accumulates more and more, the filter plate 302 will be subjected to more and more gravity compression, thereby compressing the extension spring 303. When the filter plate 302 descends to a certain position, it will squeeze the top probe of the pressure sensor 304. The pressure sensor 304 will transmit a signal to the main control room after being subjected to pressure. The main control room will control the electric heating coil 306 to start after receiving the signal, thereby performing snow melting operation.
[0034] The top surface of the filter plate 302 is fixedly connected with a mounting ring 305. The electric heating coil 306 is fixedly installed in the mounting ring 305. The top end of the mounting ring 305 is designed as an inclined surface, which can prevent rainwater or snow from accumulating on the top end of the mounting ring 305 and affecting the accuracy of the device in measuring rainwater. The electric heating coil 306 can effectively heat the inside of the device, so that the filter plate 302 is not blocked by too much snow or hail, and the device can normally perform rainwater measurement operation.
[0035] The solar panel 9, the small storage battery 10, the electric heating coil 306, the pressure sensor 304 and the water level sensor 4 involved in the present application are all prior art, and the specific working principle and installation method thereof will not be described herein.
[0036] Working principle: meteorological observer installs the device in the position suitable for measuring the amount of precipitation through the fixed bolt 7, when a large amount of snowflakes enter the precipitation collection cylinder 1, the snowflakes on the filter plate 302 will be more and more under the action of low temperature, the filter plate 302 will extrude the expansion spring 303 under the compression of gravity, when the bottom surface of the filter plate 302 contacts the pressure sensor 304, the pressure sensor 304 will transmit wireless signal to the computer of the main control room, the computer receives the signal and controls the electric heating coil 306 to start, thereby heating the inside of the precipitation collection cylinder 1, melt the snow accumulated on the filter plate 302, so that the device can accurately measure the amount of precipitation.
[0037] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
