Common types of rain gauges include tipping bucket type, siphon type and weighing type. Rain gauges have a wide range of applications, including meteorology, flood control, agriculture, hydrology and water conservancy, environmental protection, highways, airports and ports. It can provide raw data on parameters such as precipitation, precipitation intensity, and precipitation time to meteorological stations, hydrological stations, agriculture and forestry, national defense, and field monitoring stations.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] In order to solve the technical problem that the rain gauge in the prior art cannot measure solid precipitation, the utility model provides a solid precipitation detection device which can measure the solid precipitation.

[0026] See also Figure 1 , Figure 1 Schematic diagram of the structure of a solid precipitation detection device in one embodiment of the utility model. The solid precipitation detection device includes a rainfall detection mechanism 1 and a snow melting mechanism 2.

[0027] The rainfall detection mechanism 1 comprises a collecting hopper 11 and a rainfall detection component 12, wherein the inlet of the rainfall detection component 12 is connected to the outlet of the collecting hopper 11;

[0028] The snow melting mechanism 2 includes a heating tank 21, a heater 22, a water pump 23 and a flow meter 24. The heater 22 is arranged in the heating tank 21 and is used to heat the water in the heating tank 21. The inlet of the water pump 23 is connected to the heating tank 21, the outlet of the water pump 23 is connected to the inlet of the flow meter 24, and the outlet of the flow meter 24 is connected to the collecting bucket 11.

[0029] When it snows or freezes, snow or ice particles will gather in the collecting bucket 11. The staff will fill the heating tank 21 with water in advance, heat the water through the heater 22, and then pass the hot water into the collecting bucket 11 at a uniform speed through the water pump 23 to melt the snow or ice particles in the collecting bucket 11. The melted water flows out of the collecting bucket 11 to the rainfall detection component 12 below. The rainfall detection component 12 detects the amount of melted water, and then subtracts the flow of hot water detected by the flowmeter 24 to obtain the volume of the snow or ice particles, and then obtains the solid rainfall. The solid rainfall can be measured by this device.

[0030] In one embodiment, see Figure 1 and Figure 2 A filter screen 111 is provided in the collecting bucket 11, and the filter screen 111 can block snow or ice particles.

[0031] In one embodiment, see Figure 1-Figure 3The rainfall detection assembly 12 includes a base 121, a column 122, a bucket 123, a water collector 124, a reed switch 125 and a magnet 126. The column 122 is fixed to the base 121, the bucket 123 is hinged to the column 122, the bucket 123 has two symmetrical chambers, the inlet of the water collector 124 is located below the outlet of the collecting bucket 11, and the outlet of the water collector 124 is located above the bucket 123. The reed switch 125 is fixed to the column 122, and the magnet 126 is fixed to the bucket 123. When the bucket 123 rotates to a preset position, the magnet 126 is coupled to the reed switch 125. When in use, the water in the collection bucket 11 flows into the water collector 124, and then flows into a chamber of the tipping bucket 123. When the accumulated water in one chamber reaches a certain amount, the tipping bucket 123 tips over, the accumulated water flows out, and at the same time, water begins to accumulate in another chamber, and this cycle repeats. The greater the rainfall, the higher the rotation frequency of the tipping bucket 123. Every time the tipping bucket 123 rotates to a preset position, the magnet 126 will approach the reed switch 125 once, causing the reed switch 125 to be turned on. The reed switch 125 is connected to a counter, and the number of times the reed switch 125 is turned on can be obtained through the counter, thereby obtaining the flipping frequency of the tipping bucket 123 and further the amount of rainfall.

[0032] It should be understood that the present invention is not only applicable to tipping bucket rain gauges, but also applicable to other types of rain gauges.

[0033] In one embodiment, see Figure 1-Figure 3 The rainfall detection mechanism 1 also includes a protective sleeve 13 , the base 121 is fixed in the protective sleeve 13 , and the collecting bucket 11 is fixed above the protective sleeve 13 .

When the water temperature in the heating tank 21 reaches the set temperature, the heater 22 stops working. When the water temperature in the heating tank 21 is lower than the set temperature, the heater 22 starts working, thereby keeping the water temperature in the heating tank 21 constant.

The staff will fill the heating tank 21 with water in advance, heat the water through the heater 22, and then pass the hot water into the collecting bucket 11 at a uniform speed through the water pump 23 to melt the snow or ice particles in the collecting bucket 11. The melted water flows out of the collecting bucket 11 to the rainfall detection component 12 below. The rainfall detection component 12 detects the amount of melted water, and then subtracts the flow of hot water detected by the flowmeter 24 to obtain the volume of the snow or ice particles, and then obtains the solid rainfall.
