Description

Technical Field

[0001] The utility model relates to the technical field of rain gauge calibration, in particular to a design of a windproof rain gauge calibration transparent adapter tube. Background Art

[0003] Rain gauges are a common device used by meteorological departments to measure liquid precipitation. Their simple structure and easy maintenance make them a crucial tool for monitoring rainfall during severe weather events. The Meteorological Bureau requires annual calibration of rain gauges. Due to the large number of rain gauges and their distribution across townships, bureau personnel typically conduct on-site verifications with rain gauge calibration equipment. Because rain gauges are mechanical double-bucket structures, on-site verification requires removing the rain gauge to set up the calibration equipment. Windy conditions can affect calibration accuracy during this time. Rain gauges are a common device used by meteorological, hydrological, and water conservancy departments to measure liquid precipitation. Their simple structure and easy maintenance make them a crucial monitoring tool for monitoring rainfall during severe weather events. Industry regulations require regular calibration of rain gauges. Due to the large number of rain gauges and their distribution across remote townships, bureau personnel typically conduct on-site verifications with rain gauge calibration equipment. Most rain gauges have a mechanical double-bucket structure. During on-site verification, the rain gauge needs to be removed and a rain gauge calibration device needs to be installed. There are currently two types of rain gauge installation adapter tubes used: a simple adapter ring and an aluminum open-type adapter tube. The disadvantages of these two adapter tubes are: 1. Affected by wind: When calibrating in the field, if there is wind outside, it will affect the flipping of the double bucket of the rain gauge, indirectly affecting the accuracy of the calibration; 2. Inconvenient observation: It is impossible to visually observe the flipping of the internal bucket, which is not convenient for error analysis; 3. Inconvenient leveling: The adapter ring or adapter tube does not have a leveling bubble device, so a spirit level must be carried separately. Compared with the existing simple adapter ring and aluminum open-type adapter tube, the utility model not only significantly improves the windproof effect, but also facilitates error analysis, installation and leveling, and improves the efficiency of on-site calibration.

A spirit level is provided on the inner surface of one end of the calibrator base. A water outlet is provided on the inner side of the middle of the top surface of the adapter tube body.

[0007] As a further description of the above technical solution:

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0021] In the drawings, the same reference numerals all refer to the same components.

[0022] Example 1

[0023] Reference Figure 1-5 The utility model provides an embodiment: a windproof rain gauge calibration transparent adapter tube design, including a rain gauge 1, a rain gauge calibrator 2 and an adapter tube body 3, an adapter hole 4 is provided in the middle of the bottom surface of the adapter tube body 3, the adapter tube body 3 is a transparent cylindrical shell, a threading hole 5 is provided at the bottom of one side surface of the adapter tube body 3, a calibrator base 6 is provided on the top surface of the adapter tube body 3, a level 7 is provided on the inner surface of one end of the calibrator base 6, and a water outlet 8 is provided on the inner side of the middle of the top surface of the adapter tube body 3.

[0024] The adapter hole 4 is arranged in a circular groove shape, the adapter tube body 3 has a wall thickness of 5mm, a top layer thickness of 8mm, and a diameter of 231mm. The calibrator base 6 is arranged in a boss shape, and the boss height of the calibrator base 6 is set to 10mm.

[0025] The upper part of the threading hole 5 is semicircular in shape with a radius of 20 mm and a lower length of 40 mm. The adapter tube body 3 and the spirit level 7 are fixedly connected. The top surface of the spirit level 7 includes a transparent observation window. The water outlet 8 on the top surface of the adapter tube body 3 is an inward tapered groove with a circular opening in the middle.

[0026] Specifically, the structure consists of a rain gauge 1, a rain gauge calibrator 2, an adapter tube body 3, an adapter hole 4, a threading hole 5, a calibrator base 6, a spirit level 7, and a drain outlet 8, forming a windproof, transparent rain gauge calibration adapter tube design. The rain gauge 1 is an SL3-1 rain sensor used to measure ground rainfall. The tipping bucket rain gauge consists of a water collector, a tipping bucket, an adjustment screw, and a reed switch. Rainwater is collected in a water receiver and funneled into the upper tipping bucket. Once a certain amount accumulates, it is poured into the metering bucket for measurement. The reed switch closes once for every 0.1 mm of rainfall. The upper tipping bucket provides a buffer, effectively reducing rainfall loss during the tipping process of the metering bucket, thereby improving measurement accuracy. The rain gauge calibrator 2 is used for calibration or on-site verification of tipping bucket rain gauges and weighing rain gauges. The adapter tube body 3 supports and connects the rain gauge calibration equipment and the rain gauge to ensure the stability of the connection during the calibration process. The adapter tube body 3 is constructed with a transparent organic glass layer, making it easy to observe the tipping of the rain gauge 1 during the calibration process. The transparent design of the adapter tube body 3 ensures clear observation by the experimenter during the calibration process, allowing for timely detection of anomalies. The adapter hole 4 connects the adapter tube body 3 to the rain gauge 1, ensuring that the rain gauge 1 can be securely mounted on the adapter tube body 3 to prevent displacement due to wind. The threading hole 5 connects the rain gauge calibrator 2 to the rain gauge 1, ensuring smooth signal transmission, facilitating installation and removal, and ensuring that the connecting cable between the calibration equipment and the rain gauge 1 is securely fixed and free from external interference. The calibrator base 6 connects the adapter tube body 3 to the rain gauge calibrator 2, ensuring a tight connection between the devices during calibration to improve calibration accuracy. The level 7 verifies that the adapter tube body 3 is level to ensure the accuracy of the calibration data. The level 7 includes a transparent observation window containing a level bubble that accurately indicates the horizontal state of the adapter tube body 3. The standard rainfall liquid is accurately introduced into the water inlet of the rain gauge 1 through the drain port 8. This design ensures precise delivery of the standard liquid during the calibration process, ensuring consistent and reliable measurement results. The transparent adapter tube for windproof rain gauge calibration facilitates observation and analysis of error sources, facilitates leveling to increase the accuracy of measurement verification data, and facilitates connection between the calibration equipment and the rain gauge base. The sealed design provides windproof protection, enhancing the adaptability of the rain gauge calibration equipment to various environments while ensuring the accuracy of the calibration data.

[0027] Working principle: When in use, first, connect the cable to connect the rain gauge calibrator 2 cable to the rain sensor to be calibrated, place the transparent adapter tube body 3 on the rain gauge 1, and pass the rain gauge calibrator 2 cable through the threading hole 5, effectively ensuring that the circuit connection between the rain gauge calibrator 2 and the rain gauge 1 is not loose, and confirming the normal operation of the calibrator to avoid signal interruption during the calibration process and causing data errors. By observing the horizontal bubble in the spirit level 7, if the bubble is not in the center position, it is necessary to adjust the adapter tube body 3 to keep it level, place the rain gauge calibrator 2 on the adapter tube body 3, and connect the cable of the threading hole 5 to the rain gauge calibrator 2. At this time, rain calibration can be carried out. When the double buckets of the rain gauge are flipped, the flipping situation can be observed through the transparent adapter tube body 3 to check in real time whether there is any abnormality. The calibration process will not be affected by the wind, which is convenient for observation. At the same time, it can be easily leveled, which improves the overall efficiency of use.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
