Description

Technical Field

[0001] This utility model relates to the field of tipping bucket rain gauge calibration technology, and in particular to a field verification and calibration device for tipping bucket rain gauges. Background Technology

[0002] A tipping bucket rain gauge is a hydrological and meteorological instrument used to measure rainfall in nature and convert the rainfall into digital information output in the form of a switching signal to meet the needs of information transmission, processing, recording and display.

[0003] To ensure measurement accuracy, tipping bucket rain gauges require regular calibration. Traditional calibration methods typically involve disassembling the sensor and sending it to a laboratory for testing, which is cumbersome and affects the sensor's normal operation. Therefore, there is an urgent need to develop a simple, easy-to-operate on-site calibration device for tipping bucket rain gauges of different models and sizes to overcome the shortcomings in current applications and meet current requirements. Utility Model Content

[0004] The purpose of this invention is to provide an on-site verification and calibration device for tipping bucket rain gauges to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A field verification and calibration device for a tipping bucket rain gauge includes a transparent support frame, a dripping device, a stabilizing limit mechanism, a measuring cylinder, and a counter;

[0007] The transparent support frame is used to support the dripping device;

[0008] The transparent support frame is evenly distributed with three stabilizing limiting mechanisms. Each stabilizing limiting mechanism includes a limiting rod, a screw, a nut, and a toggle rod. The upper side of the limiting rod is fixed with the screw that passes through the transparent support frame. The nut is installed on the screw. The toggle rod is fixed to the side of the nut. The transparent support frame is provided with a limiting groove for the movement of the screw.

[0009] The graduated cylinder is provided with graduation lines and is used to measure the required standard water volume.

[0010] The counter is equipped with a connector for connecting to the data acquisition terminal of the tipping bucket rain gauge.

[0011] Preferably, the dripping device includes a water storage chamber, a top cover, a drip tube, and a flow regulating valve. The top cover is detachably installed on the top of the water storage chamber, the drip tube is provided at the bottom of the water storage chamber, and the flow regulating valve is installed on the drip tube.

[0012] Preferably, the transparent support frame is provided with mounting holes for locking the water storage cavity, and the water storage cavity is wider at the top and narrower at the bottom.

[0013] Preferably, the transparent support frame is provided with an operating slot for a person's hand to pass through.

[0014] Preferably, the transparent support frame is made of transparent acrylic sheet.

[0015] The beneficial effects of this utility model are as follows: When using this tipping bucket rain gauge for on-site verification and calibration, the counter connector is connected to the data acquisition end of the tipping bucket rain gauge. The transparent support frame is then placed on top of the tipping bucket rain gauge to be tested. The nut is loosened by turning the lever, and then the limiting rod and screw are moved so that the limiting rod adheres to the outer wall of the tipping bucket rain gauge. The nut is then tightened to fix the screw and limiting rod to the transparent support frame. This process of adjusting the three stabilizing limiting mechanisms clamps the tipping bucket rain gauge, allowing the transparent support frame to be stably placed on tipping bucket rain gauges of different models and sizes. Then, a dripping device is inserted into the transparent support frame, and a measured amount of water is poured into the water storage chamber using a measuring cylinder. Finally, the flow regulating valve is opened to drip water into the tipping bucket rain gauge. The counter records the number of tipping bucket rain gauge tilts. After the water has dripped completely, the data recorded by the counter is compared with the standard value to calculate the measurement error. In summary, this utility model has a simple structure and is easy to operate, and can be used for on-site calibration of tipping bucket rain gauges of different models and sizes.

[0025] Specific implementation examples are given below.

[0026] See Figures 1-6 In this embodiment of the utility model, a field verification and calibration device for a tipping bucket rain gauge includes a transparent support frame 1, a dripping device 2, a stabilizing limiting mechanism 3, a measuring cylinder 4, and a counter 5.

[0027] The transparent support frame 1 is used to support the dripping device 2.

[0028] The dripping device 2 includes: a water storage chamber 201, a top cover 202, a drip tube 203, and a flow regulating valve 204. The top cover 202 is detachably installed on the top of the water storage chamber 201. Water can be poured into the water storage chamber 201 by removing the top cover 202. The drip tube 203 is provided at the bottom of the water storage chamber 201. The flow regulating valve 204 is installed on the drip tube 203. The flow regulating valve 204 has a flow adjustment range of 0-40 ml / min.

[0029] The transparent support frame 1 is provided with an installation hole 102 for locking the water storage cavity 201. The water storage cavity 201 is wider at the top and narrower at the bottom so that it will be locked when it is gradually inserted into the installation hole 102.

[0030] The transparent support frame 1 is provided with an operation slot 103, which is used for a person to pass through. When in use, a person can pass through the operation slot 103 to adjust the flow regulating valve 204, thereby controlling the flow rate.

[0031] Three stabilizing limiting mechanisms 3 are evenly distributed on the transparent support frame 1. The stabilizing limiting mechanism 3 includes a limiting rod 301, a screw 302, a nut 303, and a toggle rod 304. A screw 302 that passes through the transparent support frame 1 is fixed on the upper side of the limiting rod 301. A nut 303 is installed on the screw 302. A toggle rod 304 is fixed on the side of the nut 303. A limiting groove 101 for the movement of the screw 302 is provided on the transparent support frame 1.

The transparent support frame 1 is then placed on top of the tipping bucket rain gauge to be tested. Next, the lever 304 is turned to loosen the nut 303. Then, the limiting rod 301 and screw 302 are moved so that the limiting rod 301 adheres to the outer wall of the tipping bucket rain gauge. Finally, the nut 303 is tightened to fix the screw 302 and the limiting rod 301 to the transparent support frame 1. This adjustment is repeated three times. Three stabilizing limiting mechanisms 3 clamp the tipping bucket rain sensor, allowing the transparent support frame 1 to be stably placed on tipping bucket rain sensors of different models and sizes. Then, the dripping device 2 is inserted into the transparent support frame 1, and a certain amount of water is measured through the measuring cylinder 4 and poured into the water storage chamber 201. Finally, the flow regulating valve 204 is opened to drip water into the tipping bucket rain sensor. The number of tipping bucket rain sensors is recorded by the counter 5. After the water has dripped out, the data recorded by the counter 5 is compared with the standard value to calculate the measurement error.
