Description

Technical Field

[0001] This utility model relates to the field of rain gauge technology, and in particular to a rain-collecting funnel and a tipping-type rain gauge that are easy to clean. Background Technology

[0002] A tipping bucket rain gauge is a widely used rainfall measurement device in meteorological monitoring, hydrological analysis, and agricultural management. Its design aims to accurately measure rainfall through a tipping bucket structure. This type of rain gauge operates on a simple and efficient principle, mainly consisting of a rain-collecting funnel, a tipping bucket, a fulcrum, and a counter or sensor. Rainwater is collected through the funnel and guided into the tipping bucket. When the water volume reaches a certain weight, the bucket tilts and pours the water out, recording one tipping event. By accumulating the number of tipping events, the total rainfall can be calculated.

[0003] However, in practical applications, the rain-collecting funnel is easily clogged by debris such as fallen leaves, dust, and insects, thus affecting the measurement accuracy of the rain gauge. This clogging problem prevents rainwater from flowing smoothly into the tipping bucket, affecting the tipping frequency and ultimately causing data errors. In the event of long-term clogging, it may even lead to instrument failure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rain-collecting funnel and a tipping-bucket rain gauge that are easy to clean, in view of the above-mentioned problems.

[0005] The technical solution adopted by this utility model is: a rain-collecting funnel that is easy to clean, characterized in that it includes:

[0006] The rain-collecting funnel body has an arc-shaped inner wall and a slag discharge port at the bottom of the inner wall. A drain pipe is connected to the slag discharge port, and at least part of the side wall of the drain pipe has an opening.

[0007] A sealing plate is provided at the slag discharge port, and the sealing plate can cooperate to block the slag discharge port and part of the opening of the drain pipe;

[0008] A slag hopper is located on the outer wall of the drain pipe, below the rainwater funnel body, and corresponding to the slag discharge port. It can receive debris falling from the slag discharge port.

[0009] A drive rod is hinged to the inner wall of the rain-collecting funnel body, and its end is connected to the sealing plate. By rotating the drive rod, the sealing plate is driven to open the slag discharge port, and the debris in the rain-collecting funnel body can fall along the inner wall onto the slag-collecting hopper.

[0010] A locking element is provided at the top of the rain-receiving funnel body. The locking element can fix the drive rod so that the closing plate keeps the slag discharge port in a closed state.

[0011] Using the above-mentioned technical means, when the rain-collecting funnel is blocked, the control drive rod drives the sealing plate to rotate, so that the slag discharge port is in the open state. Since the inside of the rain-collecting funnel body is set with an arc surface, the debris in the rain-collecting funnel can fall into the slag-collecting hopper through the slag discharge port at the bottom. The slag-collecting hopper collects the debris, effectively preventing the debris from blocking the rain-collecting funnel and keeping the rain-collecting funnel unobstructed.

[0012] In some embodiments, a hinge seat is installed on the inner wall of the rain-receiving funnel body, and the drive rod is hinged to the hinge seat via a rotating shaft. A reset member is sleeved on the rotating shaft, and the reset member can drive the sealing plate to keep the slag discharge port in an open state.

[0013] In some embodiments, an impact ball is connected to the drive rod via a connecting rod. When the drive rod drives the sealing plate to open the slag discharge port, the impact ball can impact the inner wall of the rain-receiving funnel body.

[0014] In some embodiments, the reset member is a torsion spring, which is sleeved on the rotating shaft. The two ends of the torsion spring are respectively connected to the drive rod and the hinge seat. The locking member is a hook, which is hinged to the top of the rain-collecting funnel body. The hook can hook and fix the drive rod.

[0015] In some embodiments, a sealing rubber ring is provided on the periphery of the sealing plate. When the sealing plate blocks the slag discharge port and the drain pipe, the sealing rubber ring can abut against and seal the periphery of the slag discharge port and the drain pipe opening.

[0016] In some embodiments, a slag discharge assembly is also included, the slag discharge assembly including a slag scraper and a handle, the slag scraper being provided with the handle, the top of the slag scraper being bent, the slag scraper being able to be hung on the top of the rain-collecting funnel through its bent position, and the slag scraper being connected to the drive rod via an elastic rope.

[0017] In some embodiments, the scraper blade has an internal cavity, and the top of the scraper blade is provided with a water inlet communicating with the internal cavity. The water inlet is used to add water or cleaning agent during the cleaning process of the scraper blade. The sidewall of the scraper blade is provided with a plurality of drainage holes communicating with the cavity at intervals along the length direction.

[0018] In some embodiments, the edge of the sealing plate is stepped, with the smaller stepped portion of the sealing plate abutting and fitting into the slag discharge port, and the larger stepped portion of the sealing plate abutting against the outer wall of the rain-receiving funnel body.

[0019] In some embodiments, a first drain net and a second drain net are connected to the sealing plate. The opening of the first drain net is larger than the opening of the second drain net. The first drain net and the second drain net can rotate together with the sealing plate. When the sealing plate blocks the slag discharge port and the drain pipe, the first drain net and the second drain net are both located inside the drain pipe, and the first drain net is located above the second drain net. The second drain net is set at an angle.

[0020] Another technical solution adopted by this utility model is: a tipping bucket rain gauge, characterized in that it includes:

[0021] Rain gauge body;

[0022] An easy-to-clean rain-collecting funnel is located inside the rain gauge body, and the rain-collecting funnel is used to collect rainwater.

[0023] The tipping bucket assembly is located inside the rain gauge body. The tipping bucket assembly can receive the rainwater collected by the rain funnel and pour it out when the rainwater reaches a preset amount.

[0024] A metering component is located inside the rain gauge body, and the metering component can accumulate and record the number of times the tipping bucket component tilts.

[0025] The beneficial effects of this utility model are:

[0026] 1. By operating the drive rod, the operator rotates the sealing plate, thereby controlling the opening and closing of the slag discharge port. This allows fallen leaves, dust, insects, and other debris to be quickly discharged from the slag discharge port and fall into the slag receiving hopper. This effectively prevents debris from clogging the rain receiving hopper and keeps it unobstructed, thus ensuring the normal use and measurement accuracy of the rain gauge. The locking mechanism keeps the sealing plate closed at the slag discharge port, ensuring the rain gauge can be used normally under normal circumstances.

[0027] 2. By setting up impact balls, the impact balls can strike the inner wall of the rain-collecting funnel, thereby vibrating the funnel and allowing debris such as fallen leaves, dust, and insects to fall quickly from the inner wall of the rain-collecting funnel; the first and second strainers can achieve multi-stage filtration, intercepting debris of different sizes and improving filtration efficiency; the scraper can facilitate manual cleaning and ensure the cleanliness of the inner wall of the funnel.

[0038] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0039] Example 1:

[0040] Combination Figures 1 to 4As shown, this embodiment is a rain-collecting funnel that is easy to clean. It includes a rain-collecting funnel body 2, a sealing plate 3, a slag-collecting hopper 25, a drive rod 4, and a locking element 6. The inner wall of the rain-collecting funnel body 2 is arc-shaped. A slag discharge port 21 is provided at the bottom of the inner wall of the rain-collecting funnel body 2. A drain pipe is connected to the slag discharge port 21. At least a portion of the side wall of the drain pipe has an opening. The sealing plate 3 is fitted into the slag discharge port 21, and the sealing plate 3 can cooperate to seal the slag discharge port 21 and part of the opening of the drain pipe. The slag-collecting hopper 25 is connected to the outer wall of the drain pipe. The slag-collecting hopper 25 is located below the rain-collecting funnel body 2 and corresponds to the slag discharge port 21. The slag-collecting hopper 25 can receive debris falling from the slag discharge port 21. A drive rod 4 is hinged to the inner wall of the rain-collecting funnel body 2. The drive rod 4 is long and rod-shaped. One end of the drive rod 4 is welded and fixed to the inner side of the sealing plate 3, and the other end of the drive rod 4 extends out of the rain-collecting funnel for easy gripping by workers. By rotating the drive rod 4, the closing plate 3 is moved, causing the slag discharge port 21 to open, allowing debris inside the rain-collecting funnel body 2 to fall along the inner wall onto the slag-collecting hopper 25. The top of the rain-collecting funnel body 2 is equipped with a locking element 6, which can fix the drive rod 4 so that the closing plate 3 keeps the slag discharge port 21 in a closed state.

[0041] Furthermore, the slag receiving hopper 25 is set at an angle and extends out of the outer wall of the rain gauge body 1 so that the debris discharged from the slag discharge port 21 can be discharged out of the outer wall of the rain gauge body 1.

[0042] Furthermore, such as Figure 2 and Figure 3 As shown, a hinge seat 22 is installed on the inner wall of the rain-receiving funnel body 2. A drive rod 4 is hinged to the hinge seat 22 via a rotating shaft. A reset member 5 is sleeved on the rotating shaft. The reset member 5 can drive the sealing plate 3 to keep the slag discharge port 21 in an open state. Specifically, in this embodiment, the reset member 5 is a torsion spring 51. The torsion spring 51 is sleeved on the rotating shaft. One end of the torsion spring 51 is fixedly connected to the drive rod 4, and the other end is fixedly connected to the hinge seat 22. The locking member 6 is a hook 61. The hook 61 is hinged to the top of the rain-receiving funnel body 2. The hook 61 can hook and fix the drive rod 4. Alternatively, the locking member 6 can also be made of iron wire, which can be used to bind and fix the drive rod 4.

[0043] Furthermore, such as Figure 2 and Figure 3 As shown, a connecting rod 41 is fixedly welded to the drive rod 4. An impact ball 42 is connected to the end of the connecting rod 41 away from the drive rod 4. When the drive rod 4 drives the sealing plate 3 to open the slag discharge port 21, the impact ball 42 can impact the inner wall of the rain-receiving funnel body 2. Due to the presence of the connecting rod 41, the drive rod 4 does not need to rotate too much, and the impact ball 42 can impact the inner wall of the rain-receiving funnel.

[0044] Furthermore, such as Figure 2 and Figure 3 As shown, in this embodiment, the edge of the sealing plate 3 is stepped. The smaller stepped portion of the sealing plate 3 abuts against and fits into the slag discharge port 21, while the larger stepped portion abuts against the outer wall of the rain-receiving funnel body 2. The inner side of the smaller stepped portion of the sealing plate 3 is flush with the inner wall of the rain-receiving funnel body 2. The stepped shape of the sealing plate 3 can improve the airtightness. Specifically, a sealing rubber ring 31 is fixedly bonded to the circumferential sidewall of the sealing plate 3. The sealing rubber ring 31 is used to seal the circumferential sidewall position of the slag discharge port 21. When the sealing plate 3 blocks the slag discharge port 21 and the drain pipe, the sealing rubber ring 31 can abut against and seal the circumference of the slag discharge port 21 and the drain pipe opening, thereby further sealing the slag discharge port 21 with the sealing rubber ring 31.

[0045] Rotating the hook 61 engages and secures the drive rod 4, closing the slag discharge port 21 with the sealing plate 3 in a closed state. Rotating to open the hook 61 causes the drive rod 4, under the action of the torsion spring 51, to rotate along the pivot on the hinge seat 22. The drive rod 4 opens the sealing plate 3, thus opening the slag discharge port 21, while the impact ball 42 rapidly strikes the inner wall of the rain-collecting funnel. The impact of the impact ball 42 against the inner wall of the rain-collecting funnel body 2 vibrates the funnel body, causing fallen leaves, dust, insects, and other debris to quickly fall from the inner wall, effectively cleaning the funnel.

[0046] In some implementation schemes, such as Figure 3 As shown, a first drain net 23 and a second drain net 24 are fixedly connected to the sealing plate 3. The opening of the first drain net 23 is larger than that of the second drain net 24. The first drain net 23 and the second drain net 24 can rotate together with the sealing plate 3. When the sealing plate 3 blocks the slag discharge port 21 and the drain pipe, the first drain net 23 and the second drain net 24 are both located inside the drain pipe, and the first drain net 23 is located above the second drain net 24. The second drain net 24 is set at an angle.

[0047] Multi-stage filtration can be achieved through the first screen 23 and the second screen 24, intercepting debris of different sizes, improving filtration efficiency, and extending the service life of the entire device. As the first screen 23 and the second screen 24 rotate with the sealing plate 3, debris on them can quickly fall off, improving the cleaning efficiency of the first screen 23 and the second screen 24.

[0048] In some implementation schemes, such as Figure 4As shown, this device also includes a slag discharge assembly, which includes a scraper plate 7 and a handle 73. The handle 73 is fixedly welded to the scraper plate 7. The top of the scraper plate 7 is bent, and the scraper plate 7 can be hung on the top of the rain-collecting funnel through its bent position, which facilitates the fixation of the scraper plate 7. The scraper plate 7 abuts against the inner wall of the rain-collecting funnel body 2. An elastic rope 8 is provided between the drive rod 4 and the scraper plate 7. One end of the elastic rope 8 is fixedly connected to the drive rod 4, and the other end is fixedly connected to the scraper plate 7. The elastic rope 8 can fix the scraper plate 7, facilitate the reset of the scraper plate 7 after movement, and prevent the scraper plate 7 from falling.

[0049] Furthermore, the scraper plate 7 has an internal cavity, and the top of the scraper plate 7 is provided with a water inlet 72 that connects to the internal cavity. The water inlet 72 is used to add water or cleaning agent during the cleaning process of the scraper plate 7. The side wall of the scraper plate 7 is provided with a plurality of drainage holes 71 that connect to the cavity at intervals along the length direction.

[0050] By adding water or cleaning agent to the top water inlet 72 of the scraper 7, the water or cleaning agent will be discharged from the drain hole 71. As the scraper 7 moves circumferentially along the inner wall of the rain-receiving funnel body 2, it can clean the inner wall of the rain-receiving funnel body 2 more thoroughly.

[0051] Example 2:

[0052] like Figure 5 As shown, this embodiment is a tipping bucket rain gauge, including: a rain gauge body 1, a rain-collecting funnel as described in Embodiment 1, a tipping bucket assembly, and a metering assembly. The rain-collecting funnel is located inside the rain gauge body 1 and is used to collect rainwater. The tipping bucket assembly is located inside the rain gauge body 1 and can receive the rainwater collected by the rain-collecting funnel and empty it when the rainwater reaches a preset volume. The metering assembly is located inside the rain gauge body 1 and can accumulate and record the number of times the tipping bucket assembly emptys.

[0053] The implementation principle of a tipping bucket rain gauge is as follows:

[0054] When the rain-collecting funnel is clogged with leaves, dust, insects, and other debris, the operator simply needs to turn the hook 61 to open it. The drive rod 4, under the action of the torsion spring 51, will automatically open the sealing plate 3, allowing the debris to quickly drain from the discharge port 21 into the slag-collecting hopper 25 and then slide out of the rain gauge body 1. During the process of releasing the hook 61, the impact ball 42 will strike the inner wall of the rain-collecting funnel, vibrating it and causing the debris to quickly fall from the inner wall. Then, with manual assistance, the scraper plate 7 can be pulled to clean the inner wall of the rain-collecting funnel, effectively preventing blockage and maintaining its unobstructed flow, thus avoiding any impact on the rain gauge's measurement accuracy. After cleaning, simply pull the drive rod 4 to close the sealing plate 3 and hook the hook 61 onto the drive rod 4; the rain gauge body 1 can then be used normally.

[0055] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
