Description

Technical Field

[0001] This application belongs to the field of rain gauge technology, and in particular relates to a rain gauge water inlet structure. Background Technology

[0002] A rain gauge is an instrument used by meteorologists and hydrologists to measure precipitation in a region over a period of time. Snowfall measurement requires a snow gauge. There are many types of rain gauges, the most common being siphon rain gauges, weighing rain gauges, and tipping bucket rain gauges. The water inlet structure of a rain gauge is a key component in its ability to accurately measure rainfall. Different types of rain gauges have different designs and operating principles for their water inlet structures.

[0003] For example, Chinese patent CN221841230U discloses a water inlet structure for a rain gauge, including a measuring mechanism and a filter mechanism fixedly installed on the top of the measuring mechanism. Through the cooperation of the measuring mechanism and the filter mechanism, the device is first placed in a suitable position, allowing the collection funnel to collect rainwater over a wider area. Secondly, the rainwater flows downwards through a guide plate, which allows the rainwater to flow more evenly into the filter chamber, avoiding the motor and preventing damage from contact with rainwater. Simultaneously, during normal motor operation, the motor drives the rotation... The column rotates, and a connecting ring is fitted on the outer wall of the rotating column. The connecting ring is connected to the sweeping plate. The rotation of the rotating column drives the sweeping plate to rotate. Rainwater passes through the filter screen and filters out the sand and dust particles it contains. The rotating sweeping plate collects and sweeps these particles, which are then discharged when passing through the square trough. Finally, the rainwater enters the water storage tank. Observing the scale, it can be concluded that the rainwater collection rate is improved. Although the water inlet structure of the above scheme can filter and collect rainwater, the water inlet structure cannot adjust the water flow according to the amount of rainfall, which has a significant limitation on rainwater collection and thus affects the measurement results. Summary of the Invention

[0028] To make the objectives, technical solutions, design methods, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings, provides specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0029] Reference Figure 1 This application provides a rain gauge water inlet structure, including a housing 100, a flow guide 200, an adjusting member 300, and a water collecting member.

[0030] Among them, reference Figure 1 As shown, the top of the housing 100 is provided with a water inlet 101. There is a height difference between the water inlet 101 and the top surface of the housing 100, so that rainwater can flow in smoothly from the water inlet 101. A second filter screen 102 is installed at the water inlet 101 of the housing 100, and the rainwater is filtered for the first time by the second filter screen 102.

[0031] Among them, reference Figure 1 As shown, the guide member 200 is installed in the housing 100 and the outer edge of the guide member 200 is connected to the inner wall of the housing 100 and is located below the water inlet 101. After the rainwater enters the housing 100 from the water inlet 101, it will be guided by the guide member 200 to make the rainwater collection smoother.

[0032] Among them, reference Figure 1 and Figure 2 As shown, the adjusting member 300 is installed in the housing 100 and located below the guide member 200; the adjusting member 300 includes a first disc 301 and a second disc 302, the first disc 301 is sleeved on the outside of the second disc 302 and movably connected to the second disc 302, a filter disc 303 is provided below the first disc 301 and connected to the inner wall of the housing 100, and an elastic member 305 is connected between the first disc 301 and the filter disc 303 to allow the first disc 301 to pass through the... The elastic element 305 is movably connected to the inner wall of the housing 100; the bottom surface of the second disc 302 is connected to a tube 304, one end of the tube 304 penetrates the second disc 302, the other end of the tube 304 is connected to the filter disc 303, and the side wall of the tube 304 is provided with a plurality of water outlet holes 306; the water collection element is installed in the housing 100 and connected to the bottom of the housing 100; wherein, the first disc 301 is gradually recessed from the edge to the center, and the end of the tube 304 is not higher than the surface of the second disc 302.

[0033] When the rainfall is light, rainwater flows through the guide member 200 to the first disc 301. Since the amount of rainwater is small, it can be discharged through the pipe 304 and the outlet 306 to the filter disc 303, where it is filtered and collected in the water collection device. When the rainfall is heavy, rainwater flows through the guide member 200 to the first disc 301. Since the amount of rainwater is large, the gravity of the rainwater exerts a downward force on the first disc 301, compressing the elastic member 305, causing the first disc 301 to move downwards. The first disc 301 is separated from the second disc 302. After the connection between the first disc 301 and the second disc 302 is opened, rainwater can quickly flow down from the connection hole between the first disc 301 and the second disc 302, thereby adjusting the water inflow. When the rainfall decreases, the gravity acting on the first disc 301 decreases, and the elastic element 305 gradually returns to its initial state. At this time, the first disc 301 and the second disc 302 overlap again, and the rainwater can be discharged downward from the pipe 304.

[0034] In the above, the diameter of the pipe body 304 gradually decreases from top to bottom (not shown), and as the first disc body 301 moves downward, the drainage area at the connection port of the first disc body 301 will gradually increase.

[0035] In order to ensure that the first disc 301 in the adjusting component 300 will not stick to the filter disc 303 after being pressed down and thus affecting the water intake effect, a limiting post 307 is provided on the top surface of the filter disc 303.

[0036] In the above, the water collection device includes a cylinder 400 and a first filter screen 401. The cylinder 400 is connected to the bottom of the housing 100, and the first filter screen 401 is connected to the top surface of the cylinder 400.

[0037] As one embodiment of this application, reference is made to Figure 2 and Figure 3 As shown, the first disc body 301 includes a first annular body 301a and a second annular body. The bottom end of the first annular body 301a is connected to the elastic member 305. The second annular body is connected to the inner annular surface of the first annular body 301a and is sleeved on the outside of the tube body 304. The second annular body is composed of multiple fan-shaped movable blocks 301b spliced ​​together. The ends of the movable blocks 301b away from the tube body 304 are hinged to the inner annular end face of the first annular body 301a.

[0038] In the above embodiment, when the rainfall reaches a certain amount, under the rapid impact of the rainwater, the movable block 301b will bend downward under a large force. At this time, the movable blocks separate, and the rainwater can be quickly discharged downward, which can further improve the adjustment effect of the water intake. In the above, the movable block 301b and the first annular body 301a can be connected by a torsion spring.

[0039] As one embodiment of this application, reference is made to Figure 1 As shown, the flow guide 200 includes a connecting frame 201 and a flow guide platform 202. The outer edge of the connecting frame 201 is connected to the interior of the housing 100, and the flow guide platform 202 is connected to the middle of the connecting frame 201. The flow guide platform 202 is truncated cone-shaped. Rainwater is guided and diverted by the flow guide platform 202 to flow around the periphery of the flow guide platform 202. The rainwater continues to flow downward through the connecting frame 201. The flow guide platform 202 guides the rainwater to flow around the periphery with the flow guide platform 202 as the center, and passes through the connecting frame 201, so that the rainwater flows downward in a circular shape. This ensures that the rainwater falls to the top surface of the first disc 301 at the corresponding position of the elastic member 305, so that the first disc 301 is subjected to uniform force and moves downward to open the connection surface between the first disc 301 and the second disc 302, thereby realizing the adjustment of the water inflow.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
