Description

Technical Field

[0001] This utility model relates to the field of meteorological observation, and in particular to a digital hail and rain measuring instrument. Background Technology

[0002] In the field of meteorological observation, accurate measurement of hail data is of paramount importance for meteorological research, agricultural production, and disaster early warning. Precise hail measurements help meteorologists gain a deeper understanding of the characteristics and patterns of atmospheric precipitation processes, providing crucial data support for weather forecasting models and improving the accuracy of weather predictions.

[0003] Currently, existing hail and rain measurement instruments have some shortcomings: On the one hand, the filter devices of some instruments are not designed reasonably enough, and cannot accurately separate hail and rainwater completely, resulting in deviations in measurement results. For example, some simple filter structures cannot effectively cope with hail of different sizes and complex precipitation conditions, which may cause some hail to mix into the rainwater measurement system or rainwater to mix into the hail measurement system. On the other hand, many instruments lack an effective automatic water replenishment system or their water replenishment system is not accurate and intelligent enough. When working in the field for a long time, the measurement medium (such as water) will decrease due to water evaporation or other reasons, affecting the measurement accuracy, and it cannot automatically adjust and replenish according to the actual situation. Therefore, a digital hail and rain measurement instrument is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 3This utility model provides an embodiment of a digital hail and rain measuring instrument, including a housing 1. The housing 1 is detachably equipped with four sets of baffles 2. The surface of the baffles 2 is provided with handles, which can be used to easily disassemble and open the baffles 2 to inspect the inside of the housing 1. A barrel 3 is fixedly connected to the top of the outer wall of the housing 1. A guide tube 4 is fixedly connected to the inner side wall of the barrel 3. The guide tube 4 is conical in shape, which can guide the collected hail and rain. A bracket 5 is fixedly connected to the bottom of the inner wall of the housing 1. A rain gauge drain pipe 6 is fixedly connected to the end of the bracket 5 away from the housing 1. The rain gauge drain pipe 6 is a rigid pipe. The bracket 5 can fix the installation position of the rain gauge drain pipe 6. The rain gauge drain pipe 6 passes through and is slidably connected to the inner wall of the guide plate 10.

[0030] Reference Figure 2 and Figure 3 A rainwater collection device 7 is fixedly connected to the top of the outer wall of the rainwater collection pipe 6. The surface of the rainwater collection device 7 has a notch, allowing hail to be discharged outwards from the notch when it enters the device, while rainwater enters the rainwater collection pipe 6 through the filter holes of the hail filter grid a8, then flows into the corresponding connection port 16 and falls onto the surface of the metering tipping bucket 17 for measurement. The inner side wall of the rainwater collection device 7 is fixedly connected to the hail filter grid a8, and the bottom of the inner side wall of the housing 1... A hail filter grid b9 is fixedly connected. The surface of the hail filter grid b9 has multiple sets of filter holes, so that when hail falls on the surface of the hail filter grid b9, rainwater will fall down along the filter holes of the hail filter grid b9, and the hail will enter the surface of the guide plate 10 along the inclined surface of the hail filter grid b9, thereby guiding it to the interior of the hail-rain converter 14. The rainwater drain pipe 6 passes through and is slidably connected to the inner wall of the hail filter grid b9. The bottom end of the hail filter grid b9 is fixedly connected to the guide plate 10, and the guide plate 10 is fixedly connected to the side wall of the top of the housing 1.

[0031] Reference Figure 2 and Figure 3An automatic water replenishment tank 13 is fixedly connected to the left side of the bottom of the inner wall of the housing 1. Both the buffer plate b12 and the top of the automatic water replenishment tank 13 have inlets. A hail / rain converter 14 is fixedly connected to the right side of the bottom of the inner wall of the housing 1. Two sets of bases 15 are fixedly connected to the bottom of the inner wall of the housing 1. Two sets of inlets are opened on the surface of the bases 15. By setting two sets of bases 15, rainwater falling on the surface of the metering tipping bucket 17 will cause the metering tipping bucket 17 to shake, allowing rainwater to enter the interior of the bases 15 from the inlets on both sides. A connection port 16 is fixedly connected to the top of the outer wall of the base 15. The end of the connecting pipe 18 corresponds to the left connection port 16. Rainwater drain pipe 6... The end of the device corresponds to the right connection port 16. The surface of the base 15 is rotatably connected to the metering tipping bucket 17. The side wall of the housing 1 is provided with a buffer assembly, which includes a buffer plate a11 and a buffer plate b12. The buffer plate a11 is fixedly connected to the side wall at the top of the housing 1, and the buffer plate b12 is fixedly connected to the inner side wall of the automatic water replenishment tank 13. By setting the buffer plate a11 and the buffer plate b12, the collected hail and rain can be buffered when they fall. The outer side wall of the automatic water replenishment tank 13 is fixedly connected to a connecting pipe 18. By setting the connecting pipe 18, the water inside the automatic water replenishment tank 13 can enter the corresponding connection port 16 from the connecting pipe 18 for measurement.

[0032] Working principle: When hail occurs, rainwater and hail are collected by the barrel body 3 and guided into the shell 1 through the guide tube 4. At the rainwater collector 7, due to the notch on its surface, hail will be discharged out through the notch, while rainwater will enter the rainwater drain pipe 6 through the filter holes of the hail filter grid a8, and then flow into the corresponding connection port 16 through the rainwater drain pipe 6, and finally fall on the surface of the metering tipping bucket 17. As for hail, when it falls on the surface of the hail filter grid b9, rainwater falls down along the filter holes, while hail enters the surface of the guide plate 10 along the slope, and is then guided into the hail-rain converter 14, thus realizing the initial separation and collection of hail and rain.

[0033] The metering tipping bucket 17 is rotatably connected to the surface of the base 15. The base 15 is fixed to the bottom of the inner wall of the housing 1 and has a connection port 16 on its surface. When rainwater flows into the connection port 16 through the rainwater drain pipe 6 and falls onto the surface of the metering tipping bucket 17, the metering tipping bucket 17 will shake due to gravity as the rainwater accumulates. When the water collection volume reaches a certain amount (e.g., 1mm), the metering tipping bucket 17 flips over, and the other chamber rises to the water-collecting state. When the water collection reaches the set value, it flips over again, and so on, forming a water-collecting and flipping process. During the flipping process of the metering tipping bucket 17, the magnet on its side scans the magnetic control switch on the top, and the magnetic control switch then connects to the magnetic control switch. The magnetic switch is turned on and off. Each time the magnetic switch is turned on and off, a pulse signal is output, representing 0.1 mm of precipitation. This pulse signal is output to the secondary instrument through the signal cable, thereby realizing remote measurement of precipitation and accurate recording of rainfall data. The hail-rain converter 14 is located on the right side of the bottom of the inner wall of the housing 1. Its interior is filled with a certain amount of water. When the separated hail is introduced into the hail-rain converter 14, according to Archimedes' principle, the volume of water that the hail entering the hail-rain converter 14 turns into is equal to the volume of water displaced by the hail. That is, the hail will displace water when it enters. By measuring the amount of water displaced, the amount of hail can be obtained, thereby realizing the indirect measurement and statistics of hail.

[0034] In outdoor working environments, the water level in the hail-rain converter 14 will decrease due to factors such as evaporation. When the water level in the hail-rain converter 14 drops, its built-in sensor detects the data change and triggers the water pump to work. The water pump draws water from the automatic water replenishment tank 13 into the hail-rain converter 14 to replenish it. When the water level returns to the original position, the water pump stops working. In addition, the system can also prompt the user to replenish water based on the sensor data of the automatic water replenishment tank 13. When the water level sensor of the hail-rain converter 14 detects that the water level is insufficient, the main board automatically turns on the water pump to pump water and automatically enters the calibration mode. When the system detects rainfall data in the metering tipping bucket 17 below, the system stops the water pump and automatically completes a water replenishment operation. The system also has multiple working modes such as timed water replenishment and water replenishment detected by the liquid level sensor to ensure that there is always an appropriate amount of water in the hail-rain converter 14 to ensure the accuracy and stability of the measurement data.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
