Description

Technical Field

[0001] The utility model relates to the technical field of hydrological rainfall equipment, and particularly relates to a hydrological rain gauge. Background Technique

[0002] A hydrological rain gauge is an instrument used to measure precipitation, mainly used in meteorological stations (stations), hydrological stations, environmental protection, flood control and drainage, as well as agriculture, forestry and other relevant departments. The rain gauge consists of a rain receiver, a funnel, a water storage bottle and a rain gauge cup. In addition, the specific working principle of the rain gauge is to collect rainwater through the rain receiver, and the rainwater flows into the water storage bottle through the funnel. When observation is needed, the full water storage bottle is replaced with an empty water storage bottle, and then the amount of water in the water storage bottle is measured with the rain gauge cup to obtain the precipitation, which is of great significance for water resource management, flood warning and water conservancy project planning.

[0003] During the process of using a hydrological rain gauge for rainfall monitoring in meteorology or agriculture, forestry and other relevant departments, since some impurities will be mixed in when collecting rainwater and fall into the interior of the hydrological rain gauge, it may affect the accuracy of rainwater collection and measurement. In addition, when the rainfall is large, when it is used outdoors, the equipment may be unstable and the equipment may be toppled. In order to enhance the stability of equipment use, a hydrological rain gauge with good stability needs to be designed. Content of the Utility Model

[0030] The support mechanism 2 includes a base 21 fixedly connected to the bottom end of the graduated cylinder body 1. Four ends of the base 21 are respectively rotatably connected with round rods 22. In the middle of the surface of the round rod 22, a T-shaped round plate 24 is fixedly connected. At both ends of the surface of the round rod 22, positioning rings 23 are respectively fixedly connected. A support cylinder 25 is fixedly connected to the top of the base 21. A first spring 251 is fixedly connected to the top of the support cylinder 25. A T-shaped rod 252 is fixedly connected to the top of the first spring 251. A limiting ring 26 is fixedly connected to the bottom end of the T-shaped rod 252. A dial ring 27 is fixedly connected to the surface of the limiting ring 26. A T-shaped strip 28 is fixedly connected to the surface of the dial ring 27. A positioning strip 29 is fixedly connected to the inside of the T-shaped strip 28. A ground nail 291 is fixedly connected to the left end of the T-shaped round plate 24. A positioning hole is opened inside the positioning ring 23. The surface of the positioning strip 29 matches the inside of the positioning hole. An annular groove is opened inside the support cylinder 25. The surface of the limiting ring 26 is slidably connected to the inside of the annular groove. A slot is opened on the side of the support cylinder 25. The surface of the T-shaped strip 28 is slidably connected to the inside of the slot.

[0031] Furthermore, notches are respectively opened at four ends of the base 21. One end of the T-shaped round plate 24 is located inside the notch. Round holes are respectively opened on both sides of the notch. The surface of the round rod 22 is located inside the round hole. The limiting ring 26 slides under the limitation inside the support cylinder 25. When driving the positioning strip 29 to move, it can break away from the clamping position inside the positioning ring 23. After that, the T-shaped round plate 24 can be operated and rotated, thereby driving the ground nail 291 downward and inserting it into the soft soil. Then, all the ground nails 291 are inserted into the ground. After that, release the dial ring 27 and let the positioning strip 29 be clamped into the positioning hole under the elastic support of the first spring 251. In this way, the support effect on the graduated cylinder body 1 device can be strengthened during use.

[0032] Embodiment 2

[0033] See also Figures 1-7 On the basis of the first embodiment, the filtering mechanism 3 further comprises a second spring 31, the second spring 31 is fixedly connected to the top of the scale cylinder 1, a circular plate 32 is arranged on the top of the second spring 31, a short shaft 33 is fixedly connected to the bottom of the circular plate 32, a supporting circular ring 34 is fixedly connected to the bottom of the short shaft 33, a filter screen 35 is fixedly connected to the support circular ring 34, a bolt 36 is threadedly connected to the inside of the circular plate 32, a through hole is provided inside the circular plate 32, the surface of the bolt 36 passes through the through hole provided inside the circular plate 32, a supporting hole is provided inside the top of the scale cylinder 1, and the surface of the short shaft 33 is plugged into the inside of the supporting hole.

[0034] Furthermore, threaded holes are provided at the four ends of the top of the scale cylinder 1, and the surface of the bolt 36 is threadedly connected to the inside of the threaded hole. The bolt 36 is rotated and disengaged from the top of the scale cylinder 1, and then the annular plate 32 is bounced upward under the elastic support force of the second spring 31, and then the supporting ring 34 is driven to move upward accordingly, and finally the filter screen 35 can be taken out and cleaned accordingly, thereby effectively preventing impurities from falling into the scale cylinder 1 and causing interference with the monitoring data, effectively avoiding clogging of the filter screen 35 and ensuring the normal rainwater collection effect.

[0035] In actual operation, when the device is in use, scale lines are provided on the inner side of the scale cylinder 1. During the use of the device, the device needs to be supported when placed for rainfall monitoring and is easy to store when not in use. Therefore, when support is needed, on soft soil, the dial ring 27 is pulled upward, and the limiting ring 26 is driven to slide under the limit inside the support cylinder 25, thereby driving the positioning bar 29 to move, so that it can be separated from the position inside the positioning ring 23. Then, the T-shaped circular plate 24 can be operated and rotated to drive the ground nail 291 downward and insert it into the soft soil. After that, all the ground nails 291 are inserted into the ground, and then the dial ring 27 is released and the positioning bar 29 is inserted into the positioning hole under the elastic support of the first spring 251, so that the support of the scale cylinder 1 device can be strengthened during use.

[0036] In addition, when collecting rainwater, in order to prevent impurities from falling into the inside of the graduated cylinder body 1 and causing interference to the monitoring data, it is necessary to filter the rainwater collection at this time. When the filter screen 35 needs to be sorted out after the filtration is completed, the bolt 36 is rotated at this time and disengaged from the inside of the top end of the graduated cylinder body 1. Then, under the elastic supporting force of the second spring 31, the ring plate 32 is bounced upward, and accordingly drives the supporting ring 34 to move upward, and finally the filter screen 35 can be taken out and cleaned accordingly, so as to effectively prevent impurities from falling into the inside of the graduated cylinder body 1 and causing interference to the monitoring data, effectively avoid the blockage of the filter screen 35 and ensure the normal rainwater collection effect.
