Description

Technical Field

[0001] This utility model belongs to the field of meteorological monitoring equipment, and in particular a rainfall monitoring device. Background Technology

[0002] Rainfall is a key element of the climate system. Long-term rainfall monitoring data helps meteorologists understand climate change trends. For example, analyzing rainfall records over decades or even centuries can reveal whether a region's climate is becoming wetter or drier. Existing rainfall monitoring devices can meet basic detection needs, but their ability to resist foreign object interference is weak, increasing the risk of sensor damage and measurement errors.

[0003] A search revealed a Chinese patent document (authorization announcement number CN206020697U), which discloses a rainfall monitoring device. The device includes a funnel and a water collector at the bottom of the funnel. A pressure sensor is connected to the bottom of the water collector and is connected to a data acquisition unit. The funnel, water collector, pressure sensor, and data acquisition unit are all housed within an outer casing. A support device is provided at the bottom of the outer casing, comprising a support column fixed to the bottom of the casing and three support legs evenly distributed on the support column. Each support leg is equipped with a height adjustment device. This device effectively improves installation stability and further enhances measurement accuracy in harsh environments. While this rainfall monitoring device meets basic detection requirements, its weak resistance to foreign object interference increases the risk of sensor damage and measurement errors. Utility Model Content

[0004] The purpose of this invention is to provide a rainfall monitoring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rainfall monitoring device, comprising a rainwater collection tank for storing rainfall, a cover plate on the top of the rainwater collection tank, two supports mounted on the top of the cover plate, a sliding groove connected to the side of each of the two supports, two sets of sliders sliding inside the sliding groove, a filter plate frame welded to the side of each of the two sets of sliders, a filter plate disposed inside the filter plate frame, a motor mounted on the side of the supports, the output shaft of the motor connected to a drive shaft via a coupling, a lever plate welded to the outer periphery of the drive shaft, a limit ring connected to one end of the drive shaft, and the limit ring connected to the side of the supports.

[0006] Preferably, a tapered guide plate is connected to the top of the bracket, a rain collection hopper is installed on the top of the tapered guide plate, and a connecting block is welded to the outer periphery of the rain collection hopper.

[0007] Preferably, a fixing plate is installed on both sides of the slider, and a rotating shaft is rotatably connected to the side of the fixing plate.

[0008] Preferably, a limiting plate for limiting the displacement of the filter plate is welded to the outer periphery of the rotating shaft, and a spring is installed between the limiting plate and the fixing plate.

[0009] Preferably, the rainwater collection tank is connected to a plurality of partitions on its outer periphery, and a protective tank is installed on the side of the partitions away from the rainwater collection tank. A plurality of rain gauges for monitoring are installed on the outer periphery of the protective tank.

[0010] Preferably, a connecting wire is connected to the side of the motor, and the end of the connecting wire away from the motor is connected to a power source.

[0011] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0012] This rainfall monitoring device, thanks to its filter plate and deflector structure, uses a filter plate to filter incoming rainwater, blocking impurities between the conical guide plate and the filter plate. A motor drives the drive shaft and deflector to rotate, cleaning the impurities from the filter plate. Due to the deflector's structure, it can scrape impurities from the filter plate to both sides of the slide groove, preventing them from affecting the sliding of the filter plate holder on the groove. The movable filter plate holder moves a slider inside the groove, moving the used filter plate away from the conical guide plate for replacement. A new filter plate holder and filter plate are moved below the conical guide plate. Compared to traditional rainfall monitoring devices with weaker resistance to foreign object interference, this structure increases resistance to foreign object interference, reduces the risk of sensor damage, and lowers measurement errors.

[0013] Thanks to the structure of the limiting plate, when the filter plate is replaced, the spring causes the rotating shaft to drive the limiting plate to contact the filter plate, thus initially fixing the filter plate and preventing it from falling off.

[0014] This rainfall monitoring device benefits from the structure of the partition and protective barrel, which prevents rainwater from evaporating from the barrel and affecting the monitoring accuracy. Attached Figure Description

[0023] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0024] like Figures 1 to 4The rainfall monitoring device shown includes a rainwater collection tank 103 for storing rainfall. A cover 104 is provided on the top of the rainwater collection tank 103, and two supports 5 are mounted on the top of the cover 104. Each support 5 has a sliding groove 204 connected to its side. Two sets of sliders 203 slide inside the sliding grooves 204. Filter plate frames 205 are welded to the sides of each set of sliders 203. Filter plates 206 are installed inside the filter plate frames 205. The main function of the filter plates 206 is to prevent debris such as leaves, branches, and insects from entering the rainwater collection device. The pore size of the filter plates 206 is typically around 2-5 mm, a size that effectively blocks most foreign objects without significantly hindering the entry of rainwater. The filter plates 206 are generally woven from stainless steel wire, possessing good corrosion resistance and mechanical strength, allowing for long-term use in outdoor environments without damage. Rainwater enters the rainwater collection hopper 2 and comes into contact with the filter plate 206 through the conical guide plate 202. The filter plate 206 filters the incoming rainwater, and impurities are blocked between the conical guide plate 202 and the filter plate 206. The filtered rainwater enters the rainwater collection tank 103. After a period of time, the movable filter plate frame 205 moves the slider 203 inside the slide groove 204, moving the used filter plate 206 away from the conical guide plate 202. The used filter plate 206 can then be removed for replacement. The new filter plate frame 205 and filter plate 206 are moved to a position below the conical guide plate 202. A motor 4 is installed on the side of the bracket 5. The output of the motor 4... A drive shaft 401 is connected to the shaft via a coupling. A lever plate 402 is welded to the outer periphery of the drive shaft 401. A limit ring 403 is connected to one end of the drive shaft 401. The limit ring 403 is connected to the side of the bracket 5. When the motor 4 is turned on, the motor 4 drives the drive shaft 401 and the lever plate 402 to rotate. The lever plate 402 cleans the impurities on the filter plate 206. Due to the structure of the lever plate 402, the lever plate 402 can scrape the impurities on the filter plate 206 to both sides of the slide groove 204, preventing the scraped impurities from affecting the sliding of the filter plate frame 205 on the slide groove 204. A connecting line 601 is connected to the side of the motor 4. The end of the connecting line 601 away from the motor 4 is connected to a power supply 6.

[0025] A tapered guide plate 202 is connected to the top of the bracket 5, and a rain collection hopper 2 is installed on the top of the tapered guide plate 202. A connecting block 201 is welded to the outer periphery of the rain collection hopper 2.

[0026] Both sides of the slider 203 are equipped with fixing plates 3. The side of the fixing plate 3 is rotatably connected to a rotating shaft 302. A limiting plate 303 is welded to the outer periphery of the rotating shaft 302 to limit the displacement of the filter plate 206. A spring 301 is installed between the limiting plate 303 and the fixing plate 3. When the filter plate 206 is replaced, due to the action of the spring 301, the rotating shaft 302 drives the limiting plate 303 to contact the filter plate 206, and initially fixes the filter plate 206 to prevent the filter plate 206 from falling off.

[0027] Multiple partitions 102 are connected to the outer periphery of the rainwater collection tank 103. A protective tank 1 is installed on the side of the partitions 102 away from the rainwater collection tank 103. Multiple rain gauge viewing mirrors 101 for monitoring are installed on the outer periphery of the protective tank 1. The rainfall inside the rainwater collection tank 103 can be observed through the rain gauge viewing mirrors 101. The partitions 102 and the protective tank 1 prevent the rainwater inside the rainwater collection tank 103 from evaporating and affecting the monitoring accuracy. Utilizing the conductivity of rainwater, the capacitance changes when raindrops fall on the electrode plates of the sensor. This rainfall monitoring device includes other necessary components. For example, the rainfall monitoring device calculates the rainfall by detecting the change in capacitance. This type of sensor is more sensitive to minute rainfall and has higher accuracy, but it is not the innovative direction of this rainfall monitoring device and will not be described in detail.

[0028] Working principle

[0029] In use, this rainfall monitoring device allows rainwater to pass through the rain collection hopper 2 and the conical guide plate 202, contacting the filter plate 206. The filter plate 206 filters the incoming rainwater, trapping impurities between the conical guide plate 202 and the filter plate 206. The filtered rainwater then enters the rainwater collection tank 103. The motor 4 is activated, driving the drive shaft 401 and the agitator 402 to rotate. The agitator 402 cleans the impurities on the filter plate 206. Due to its structure, the agitator 402 can scrape impurities from the filter plate 206 to both sides of the slide groove 204, preventing the scraped impurities from affecting the sliding of the filter plate frame 205 on the slide groove 204. After a period of time, the filter plate frame 205 can be moved, and the filter plate... The frame 205 drives the slider 203 to slide inside the slide groove 204, moving the used filter plate 206 away from the conical guide plate 202. The used filter plate 206 can be removed for replacement. The new filter plate frame 205 and filter plate 206 are moved to the bottom of the conical guide plate 202. When replacing the filter plate 206, due to the action of the spring 301, the rotating shaft 302 drives the limiting plate 303 to contact the filter plate 206, which initially fixes the filter plate 206 and prevents it from falling off. The rainfall in the rainwater collection tank 103 can be observed through the rainwater observation mirror 101. The partition 102 and the protective tank 1 can prevent the rainwater in the rainwater collection tank 103 from evaporating and affecting the monitoring accuracy.
