Description

Technical Field

[0001] This utility model relates to the field of meteorological science popularization technology, and more specifically to a teaching tool for a double-tumbling bucket rain gauge with self-counting function. Background Technology

[0002] Accurate rainfall measurement is crucial in numerous fields, including meteorological monitoring, hydrological research, agricultural irrigation, and urban drainage. Accurate rainfall data is indispensable for accurate weather forecasting, water resource management, flood warnings, and agricultural production decisions.

[0003] Traditional rainfall measurement methods and equipment have many limitations. For example, the most common simple rain gauge can only measure rainfall by manually reading the depth of water inside the gauge at regular intervals. This method is not only inefficient and cannot obtain data in real time, but its measurement accuracy is also easily affected by human factors, such as reading errors and rainwater evaporation.

[0004] Early single-tip bucket rain gauges partially solved the problem of automatic measurement, measuring rainfall by counting the amount of rainwater falling into the bucket and causing it to flip. However, single-tip bucket rain gauges revealed significant shortcomings in practical applications. Due to their relatively simple structure, the bucket is easily affected by uneven raindrop impact and external factors such as wind during the flipping process, resulting in limited measurement accuracy. Especially when rainfall intensity varies greatly, single-tip bucket rain gauges struggle to accurately capture real-time changes in rainfall. Measurement errors are prone to occur with light rainfall, while in heavy rainfall, the high flipping frequency can lead to inaccurate counting.

[0005] With the development of technology and the increasing demands for accuracy in rainfall data across various industries, existing rainfall measurement equipment can no longer meet practical needs. There is an urgent need for a new type of rainfall measurement device that can overcome the shortcomings of traditional equipment, improve measurement accuracy and stability, adapt to different rainfall conditions, and possess real-time monitoring capabilities. The dual-tipping bucket rain gauge was developed in this context, aiming to provide more accurate and reliable rainfall measurement solutions for various fields.

[0006] The double-tip rain gauge is just a type of meteorological sensor, usually existing as a sensor component in a rainfall measurement and observation system. The system's data acquisition relies on an online data logger connected to a computer and acquisition software to obtain real-time rainfall and display the results. At the same time, the double-tip rain gauge has an iron outer wall cylinder, so the special operation mode of the double tipping bucket cannot be directly observed during rainfall measurement. In addition, as an observation equipment, the double-tip rain gauge is relatively expensive.

[0007] Furthermore, current popular science explanations of rainfall measurement and observation systems only cover the double-tipping bucket rain gauge sensor. People cannot see the counting process of the electrical components and can only count manually. They cannot see the data acquisition process or the data display. They cannot see the flow of rainwater from the "rain collector" to the "tipping bucket" or the physical counting process involved when the bucket is tipped. The double-tipping bucket rain gauge sensor used is prone to damage to components and affects the measurement accuracy of the sensor, resulting in property damage. Utility Model Content

The base is equipped with a rainfall simulation measurement module for simulating rainfall measurement and a proximity switch for sensing the information measured by the rainfall simulation measurement module.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] A teaching aid for a double-tip bucket rain gauge with self-counting function, combined with Figure 1 As shown, it includes a rain gauge and a data module 14. The rain gauge is used to simulate and measure rainfall, and the data module 14 is used to collect the simulated rainfall information. The data module is electrically connected to the rain gauge.

[0023] The rain gauge includes a matching base 12 and a transparent outer tube 13. The transparent outer tube is made of polymer material and allows direct observation of the entire process of rainwater simulation measurement. The base 12 is equipped with a rain volume simulation measurement module and a proximity switch 11. The rain volume simulation measurement module is used to simulate and measure rainfall, and the proximity switch 11 is used to sense the information measured by the rain volume simulation measurement module. The output of the proximity switch is connected to the input of the data module.

[0024] The rainfall simulation measurement module includes a water collector 1, a funnel 4, an upper tipping bucket 6, a collecting funnel 7, a metering tipping bucket 9, and a counting tipping bucket 10 arranged from top to bottom. A proximity switch 11 is located below the counting tipping bucket 10. There are two proximity switches, symmetrically arranged below the counting tipping bucket. Each time the counting tipping bucket flips, the proximity switch collects information once.

[0025] The bottom of the water collector 1 is fitted with a mesh cover 2 by cleaning and removing the nut 3, which is used to filter impurities in the rainwater.

[0026] The upper tipping bucket 6 is equipped with a positioning screw 5 to adjust the water accumulation volume, and the metering tipping bucket 9 is equipped with a capacity adjustment screw 8 to adjust the capacity of the metering tipping bucket. Rainwater is collected by the water collector and enters the upper tipping bucket through the funnel. When a certain amount is accumulated, the weight increases and causes the upper tipping bucket to tip over. Rainwater then enters the metering tipping bucket through the collecting funnel. When the metering tipping bucket reaches the set water volume, it flips the water into the counting tipping bucket, causing the counting tipping bucket to tip over. Each time the counting tipping bucket tip over, the proximity switch collects information and sends the information to the data module for processing.

[0027] The data module 14 includes an energy storage battery, a display, a controller, and a memory. The energy storage battery provides electrical energy, the display shows data information, the controller processes the data collected by the proximity switch, and the memory stores the data information. The output terminal of the energy storage battery is connected to the power input terminal of the controller, the output terminal of the proximity switch is connected to the input terminal of the controller, and the output terminal of the controller is connected to the input terminals of the display and the memory, respectively.

[0028] The data module 14 is connected to the proximity switch via wired or wireless means. The data module 14 can exist as an independent unit, or it can be placed inside the transparent outer wall cylinder. It can also be embedded in the cylinder wall as a whole, so that the teaching aid is not affected by time, space and external environment, and can realize data acquisition, data calculation, data storage and data display entirely through its own functions.

[0029] In this invention, a proximity switch is used to measure and count the swing information of the tipping bucket. Each time the tipping bucket's swing arm passes the proximity switch, the data module acquires the original signal sent by the proximity switch, performs a calculation, stores the data, and displays it, thereby realizing the offline operation of the rain gauge teaching aid.
