Description

Technical Field

[0001] The invention relates to the technical field of meteorological observation equipment, and in particular to a precipitation and evaporation observation device. Background Art

[0002] Precipitation observation is a key link in weather forecasting. Through real-time monitoring of precipitation, meteorologists can predict information such as the duration and intensity changes of precipitation. These data, combined with meteorological models, can also predict the range of precipitation, such as whether it is a local rainstorm or a large-scale regional rainfall. Long-term accumulated precipitation data is crucial for studying climate change patterns. Scientists can understand the periodic changes in precipitation by analyzing many years of precipitation data. The evaporation process is an important part of the energy balance on the earth's surface. Evaporation observation data can help scientists better understand the energy exchange process between the earth's surface and the atmosphere. In climate models, evaporation is a key parameter that is interrelated with meteorological elements such as temperature, humidity, and wind speed. Accurate evaporation data helps to improve the accuracy of climate models and better simulate the operating mechanisms of atmospheric circulation and climate systems;

[0003] The utility model with application number 202121120256.8 discloses a device for measuring frontal rain precipitation and evaporation. Through the cooperation of a raindrop sensor, a motor, a processor, a rotating shaft, a connector, and a shielding cover, the shielding cover does not shield the evaporation measuring device in the initial state, which is convenient for adding water to the evaporating dish or taking out the evaporating dish. After the raindrop sensor senses rainfall, the rotating shaft drives the shielding cover to rotate, and the shielding cover shields the evaporation measuring device to prevent rainwater from falling into the evaporating dish, thereby realizing intelligent adjustment of the evaporation measuring device between the shielding state and the open state. By setting a certain gap between the side and top of the evaporating dish and the second shell, the evaporating dish is not in direct contact with the second shell, thereby reducing the influence of the vibration of the second shell on the weighing measurement of the evaporating dish, which is conducive to enhancing the measurement accuracy. By setting a pad between the tray and the evaporating dish, the evaporating dish can be placed on the tray more stably, and at the same time, it can play a certain shock-absorbing role to avoid the measurement being affected as much as possible.

[0004] However, in the above-mentioned device for measuring frontal rainfall and evaporation, the rainwater is directly received by the beaker, which easily causes impurities in the rainwater to fall into the beaker and precipitate. Under the influence of the impurity precipitation, the measurement result is easily inaccurate. In the above-mentioned device for measuring frontal rainfall and evaporation, part of the rainwater received in the beaker will also evaporate after the rainfall, affecting the measurement accuracy. Therefore, the present invention proposes a precipitation and evaporation observation device to solve the problems existing in the prior art. Summary of the invention

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0022] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides a precipitation and evaporation observation device, including an observation platform 1, a water receiving and filtering mechanism, a weighing and observation mechanism and a rotating and closing mechanism. The water receiving and filtering mechanism includes a first bracket 2, a water receiving bucket 3, an arc-shaped filter screen 4, a sewage discharge spiral shaft 5, a first motor 6, a sewage pipe 7 and an opening and closing sewage discharge mechanism. The first bracket 2 is fixedly provided in the middle of the observation platform 1, the water receiving bucket 3 is symmetrically fixedly provided on the first bracket 2, the arc-shaped filter screen 4 is fixedly provided at the lower part of the water receiving bucket 3, and a sewage discharge spiral shaft 5 is rotatably provided above the arc-shaped filter screen 4. The first motor 6 is symmetrically fixedly provided on the rear side of the first bracket 2, and the output end of the first motor 6 is drivingly connected to the sewage discharge spiral shaft 5. A sewage pipe 7 is provided on the front side of the square, and an opening and closing sewage mechanism is symmetrically provided on both sides of the first bracket 2. A weighing and observation mechanism is symmetrically provided on the observation platform 1. A rotating closing mechanism is provided in the middle of the observation platform 1. When rainwater is received by the water receiving bucket 3, impurities in the rainwater are filtered out by the arc filter screen 4, which effectively prevents the impurities from affecting the weighing and observation of precipitation by the pressure sensor 12. When impurities need to be cleaned, the first motor 6 drives the sewage discharge spiral shaft 5 to rotate to push the impurities filtered on the arc filter screen 4 to be discharged from the sewage pipe 7, thereby realizing automatic cleaning and solving the problem that impurities in the rainwater fall into the beaker and precipitate, causing the pressure sensor 12 to have inaccurate measurement results under the influence of impurity precipitation.

[0023] The opening and closing sewage discharge mechanism includes a fixed plate 8, an electric telescopic rod 9 and a sealing plug 10. The fixed plate 8 is symmetrically fixed on the rear side of the first bracket 2, and the electric telescopic rod 9 is matched and fixed on the front side of the fixed plate 8. A sealing plug 10 is fixed on the telescopic end of the electric telescopic rod 9. The end of the sewage pipe 7 is tilted upward, and the sealing plug 10 is located in front of the outlet of the sewage pipe 7. When impurities need to be discharged, the electric telescopic rod 9 drives the sealing plug 10 to be pulled out of the sewage pipe 7 from the depth to facilitate the discharge of impurities. When the impurities are cleaned, the electric telescopic rod 9 retracts and drives the sealing plug 10 to move and block the sewage pipe 7 to prevent rainwater from flowing out of the sewage pipe 7 when it rains.

[0024] The weighing and observation mechanism includes an observation chamber 11, a pressure sensor 12, a support plate 13 and a water receiving box 14. The observation chamber 11 is symmetrically fixed on the observation platform 1. The bottom of the observation chamber 11 is equipped with a pressure sensor 12, and a support plate 13 is equipped with a sensing end above the pressure sensor 12. A water receiving box 14 is placed on the support plate 13. The support plate 13 is close to the inner wall of the observation chamber 11, and the water receiving box 14 corresponds to the upper and lower positions of the lower end of the water receiving bucket 3. When it rains, rainwater flows into the water receiving box 14 through the water receiving bucket 3, and the pressure sensor 12 weighs the weight change of the water receiving box 14 to measure the precipitation.

[0025] The rotating and closing mechanism includes a second bracket 15, a second motor 16, a rotating shaft 17, a sealing plate 18, a guide ring 19, a connecting rod 20 and a slider 21. The second bracket 15 is fixedly provided in the middle of the observation platform 1, the second motor 16 is fixedly provided at the bottom of the second bracket 15, a sealing plate 18 is fixedly provided at the upper end of the rotating shaft 17, a guide ring 19 is fixedly provided at the bottom of the first bracket 2, a connecting rod 20 is fixedly provided on one side of the sealing plate 18, a slider 21 is fixedly provided at the upper end of the connecting rod 20, a rotating shaft 17 is driven and rotated at the output end of the second motor 16, the slider 21 is slidably matched with the outer side of the guide ring 19, and the water receiving bucket 3 is provided with a plurality of connecting rods 20. A rainwater sensor 22 is fixedly provided on the outside and is electrically connected to the second motor 16. When a certain amount of water is poured into the water receiving box 14 on one side, the sealing plate 18 is pressed on the observation chamber 11 on one side to seal it, preventing external rainwater from flowing in and affecting the observation accuracy of evaporation measured by the pressure sensor 12 on one side. When the rain stops, the rainwater sensor 22 senses it in time and the second motor 16 drives the rotating shaft 17 and the sealing plate 18 to rotate 180° to seal the observation chamber 11 on the other side, effectively preventing the evaporation of rainwater in the other set of water receiving boxes 14 containing rainwater from affecting the observation accuracy of weighing precipitation.

[0026] A display 23 is fixedly provided on the front side of the observation platform 1, and a signal transmitter 24 is fixedly provided on the other front side of the observation platform 1. The display 23 and the signal transmitter 24 are both electrically connected to the pressure sensor 12. The display 23 displays the pressure changes sensed by the two groups of pressure sensors 12 in real time, and the signal transmitter 24 synchronously sends the pressure values ​​to the outside.

[0027] When the precipitation and evaporation observation device is conducting observation and measurement, a certain amount of water is first poured into the water receiving box on one side and the pressure value is recorded through the pressure sensor. When it rains, the rain sensor senses the rain and then the second motor drives the shaft to rotate to drive the sealing plate to cover the water receiving box on one side to prevent rainwater from falling into the water receiving box on one side and affecting the observation of evaporation. At the same time, rainwater flows into the water receiving box on the other side through the water receiving bucket. The pressure sensor measures the pressure change of the water receiving box in real time to calculate the precipitation. When the rain stops, the second motor drives the shaft and the sealing plate to rotate to cover the water receiving box on the other side to prevent rainwater evaporation from affecting the measurement accuracy of precipitation. One side of the water receiving tank is opened when it is not raining to measure evaporation, and the other set of water receiving tanks is opened when it is raining to measure precipitation and display and transmit the pressure data changes measured by the pressure sensor in real time through the display and signal transmitter, thereby inverting the precipitation and evaporation. At the same time, the arc filter screen filters out impurities from the rainwater to prevent impurities from settling in the water receiving tank and affecting the measurement accuracy of the precipitation. When it is necessary to clean the impurities, the electric telescopic rod extends to drive the sealing plug to move and pull it out from the end of the sewage pipe. At the same time, the first motor starts to drive the sewage spiral shaft to rotate to push the filtered impurities to be discharged from the sewage pipe, thereby realizing automatic cleaning of mud and sand impurities in the rainwater.
