Description

Technical Field

[0001] The utility model relates to the field of meteorological detection, in particular to a rain gauge for meteorological detection. Background Art

[0002] A rain gauge is a special instrument used to collect precipitation. It is used to measure the precipitation in millimeters through a matching rain gauge. It is suitable for use by meteorological stations, hydrological stations, environmental protection, flood control and drainage, as well as agriculture, forestry and other relevant departments to measure precipitation.

[0003] For example, the patent number CN217112774U discloses a highly practical rain gauge for meteorological detection, including a water storage cylinder, a base is fixedly installed at the lower end of the water storage cylinder, a fixing mechanism is fixedly connected to the outer surface of the water storage cylinder, and the fixing mechanism is threadedly connected to the base, a water outlet is fixedly installed at the lower part of the outer surface of the water storage cylinder, a connecting cylinder is fixedly installed at the middle part of the upper end of the water storage cylinder, an observation window is provided on the front of the outer surface of the connecting cylinder, scales are provided on the left and right sides of the observation window, and a filtering mechanism is fixedly connected to the upper end of the connecting cylinder.

[0004] In the above scheme, the amount of rain is obtained by observing the scale on the connecting tube. However, in actual use, it is found that when it rains heavily and the rain does not stop, if the amount of rain is to be known, the inspector needs to be close to the water storage tube. However, due to poor visibility on rainy days, rain will also hit the scale to cause obstruction, making it extremely inconvenient to observe the amount of rain, and the inspector cannot quickly record the amount of rain. Therefore, a rain gauge for meteorological detection is proposed. Utility Model Content

[0005] In view of the above problems existing in the existing rain gauge for meteorological detection, the present utility model is proposed.

[0006] Therefore, the utility model aims to provide a rain gauge for meteorological detection, which solves the problems raised by the background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A rain gauge for meteorological detection comprises a water storage cylinder, a water receiving bucket is fixedly provided on the top of the water storage cylinder, and a filter net is detachably provided at the bottom water outlet of the water receiving bucket; a floating rod is provided on one side of the interior of the water storage cylinder, a floating ball is fixedly provided on the lower end of the floating rod, and the upper end of the floating rod extends to the outside of the water storage cylinder and is fixedly provided with a floating head, and the rod wall of the floating rod is provided with a first scale line along its length direction.

[0009] Preferably, the water receiving bucket is concavely arranged toward the inside of the water storage cylinder.

[0010] Preferably, a supporting ring is fixedly provided inside the water outlet of the water receiving bucket, a movable tube is placed on the top of the supporting ring, and the filter is fixedly arranged inside the movable tube.

[0011] Preferably, the water storage cylinder adopts a PVC transparent cylinder, and the outer side wall of the water storage cylinder is provided with a second scale line along the vertical direction.

[0012] Preferably, the float ball is a PVC hollow sphere, and the float rod is a PVC hollow rod.

[0013] Furthermore, a fluorescent mark is provided on the side wall of the floating head.

[0014] Preferably, a drain pipe is fixedly provided at the bottom of the side wall of the water storage cylinder, and a switch valve is provided on the pipe wall of the drain pipe.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] The utility model collects rainwater through a water collecting bucket and stores it inside the water storage cylinder through a float rod, a float ball and a float head arranged on the water storage cylinder. At this time, the float ball, the float rod and the float head are lifted upward by the buoyancy of the rainwater, and the lifted float rod and the float head are extended to the outside of the water storage cylinder. At this time, an inspector can directly observe the positions of the float rod and the float head, and the inspector can roughly judge the amount of rainwater collected inside the water storage cylinder by the height of the extended float rod and the float head from a distance. The amount of rainwater can be quickly observed and recorded without being in the rainwater. In this process, the liquid level height of the rainwater collected inside the water storage cylinder is the lifting height of the float rod and the float head.

[0017] The utility model has a filter net arranged inside the water receiving bucket, and after rainwater falls into the water receiving bucket, impurities can be filtered out through the filter net. When a large amount of impurities are collected on the surface of the filter net, the movable pipe is directly removed from the top of the supporting ring, so that the filter net can be taken out and the impurities can be cleaned.

[0018] The utility model provides a first scale line and a second scale line, so that a tester can know the raised height of the float rod by observing the first scale line, and can know the amount of rainwater collected in the water storage cylinder by observing the second scale line.
