Description

Technical Field

[0001] This utility model relates to the field of rainfall measurement, specifically a tipping bucket rain gauge with anti-clogging function. Background Technology

[0002] A rain gauge is an instrument used to measure the amount of rainfall in a region over a period of time. There are many types of rain gauges, the most common being siphon rain gauges, weighing rain gauges, tipping bucket rain gauges, and so on. Among them, the tipping bucket rain gauge is widely used and easy to use. It measures rainfall using a single or multiple tipping buckets. A typical tipping bucket rain gauge usually includes a funnel and a water collector with a tipping bucket. Rainwater continuously enters the water collector from the top inlet, gradually increasing the water level in the tipping bucket until it loses balance and tips over. Each tipping activates a switch, sending a pulse signal to the recorder, which then calculates the accumulated rainfall.

[0003] However, in actual use, conventional tipping bucket rain gauges, when exposed to outdoor conditions for extended periods, will gradually accumulate mud and sand, eventually clogging the water outlet under the inlet funnel, causing the rain gauge to malfunction and become unable to measure. Utility Model Content

[0004] The purpose of this invention is to provide a tipping bucket rain gauge with anti-clogging function to solve the problem that the rain gauge cannot measure the water level because the inlet funnel is blocked by mud and sand.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tipping bucket rain gauge with anti-clogging function, comprising:

[0006] outer cylinder;

[0007] A filter assembly for filtering rainwater is installed at the top of the outer cylinder. The filter assembly includes a rain-collecting port that is threaded to the top of the inner wall of the outer cylinder. A first filter screen is fixedly provided on the inner wall of the rain-collecting port, and a water-filtering cover is provided at the bottom of the rain-collecting port, so that rainwater passes through the first filter screen and the water-filtering cover in sequence and is discharged from the bottom of the rain-collecting port.

[0008] An anti-clogging component is installed in the middle of the outer cylinder to prevent the accumulation and caking of mud and sand. The anti-clogging component includes a water inlet funnel located directly below the rain inlet. An upper cover is fixedly installed on the inner wall of the water inlet funnel. A lower cover is fixedly connected to the bottom of the upper cover. A reduction motor is fixedly installed between the upper cover and the lower cover. The output shaft of the reduction motor is fixedly connected to a mud and sand scraper. The mud and sand scraper moves through the lower cover and is rotatably connected to the bottom of the inner wall of the water inlet funnel. The rotation of the mud and sand scraper drives the accumulated and caking mud and sand at the bottom of the water inlet funnel and discharges it downward with the rainwater.

[0009] A metering component installed at the bottom of the outer cylinder for measuring rainwater.

[0010] Preferably, the bottom of the rain-collecting opening is threadedly connected to a fixed bottom cover, the fixed bottom cover has a drainage hole in the middle, the bottom of the water filter cover has a sealing edge, the surface of the water filter cover is movably fitted with a fixed top cover and supported by the sealing edge, the fixed top cover is threadedly connected to the inner wall of the fixed bottom cover so that the fixed top cover cooperates with the sealing edge to restrict the water filter cover to the inner wall of the fixed bottom cover.

[0011] Preferably, the top of the filter cover has multiple filter holes, the surface of the filter cover has multiple filter grooves, the top of the fixed top cover has multiple water inlet notches, and the bottom of the sealing edge has a sealing ring that fits tightly against the inner wall of the fixed bottom cover, so that rainwater entering the rain inlet can only enter the interior of the filter cover through the filter holes or filter grooves, thereby achieving a filtering effect.

[0012] Preferably, a second filter screen is fixedly connected to the inner wall of the water inlet funnel, and the top cover is fixedly connected to the middle of the second filter screen.

[0013] Preferably, the silt scraper is a cylindrical structure that avoids having a water channel, so that the silt scraper does not affect the normal flow of rainwater when it is working.

[0014] Preferably, the bottom of the lower cover is provided with a detection probe, and the detection probe is a water immersion sensor probe.

[0015] Preferably, the metering component includes a base threaded to the bottom of the inner wall of the outer cylinder, a tipping bucket bracket fixedly connected to the top of the base, an upper tipping bucket rotatably connected to the top of the tipping bucket bracket, a stepped controlled-release water injection funnel fixedly connected to the middle of the bottom position of the tipping bucket bracket corresponding to the upper tipping bucket, and a metering tipping bucket and a counting tipping bucket rotatably connected to the middle of the bottom position of the tipping bucket bracket corresponding to the stepped controlled-release water injection funnel, with the metering tipping bucket located on top of the counting tipping bucket.

[0016] Preferably, a level is fixedly connected to one end of the bottom of the tipping bucket support, and a drainage bucket is fixedly embedded in the bottom of the base corresponding to the tipping bucket position.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a geared motor to drive a mud scraper to rotate at the bottom of the water inlet funnel, scraping the mud on the inner wall of the bottom of the water inlet funnel. This prevents the mud from hardening in the narrow space at the bottom of the water inlet funnel, so that the mud entering the water inlet funnel is stirred by the mud scraper and washed away with the rainwater, thus ensuring the smooth flow of water out of the bottom of the water inlet funnel; 2. This utility model also sets a fixed top cover and a fixed bottom cover with a threaded connection, so that the fixed top cover can be used with the sealing edge to lock the water filter cover on the inner wall of the rain inlet, and the sealing edge presses the sealing ring on the inner wall of the fixed bottom cover, so that the rainwater can only enter the interior of the water filter cover after passing through the filter holes and filter tanks, filtering out large impurities in advance and reducing the workload of the anti-clogging components.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 This utility model provides a technical solution: a tipping bucket rain gauge with anti-clogging function, comprising:

[0031] outer cylinder 1;

[0032] A filter assembly for filtering rainwater is installed at the top of the outer cylinder 1. The filter assembly includes a rain-collecting port 201 threadedly connected to the top of the inner wall of the outer cylinder 1. A first filter screen 202 is fixedly installed on the inner wall of the rain-collecting port 201. A water-filtering cover 205 is provided at the bottom of the rain-collecting port 201 so that rainwater passes through the first filter screen 202 and the water-filtering cover 205 in sequence and is discharged from the bottom of the rain-collecting port 201. A fixed bottom cover 203 is threadedly connected to the bottom of the rain-collecting port 201. A drain hole is provided in the middle of the fixed bottom cover 203. A sealing edge 209 is provided at the bottom of the water-filtering cover 205. A fixed top cover 204 is movably sleeved on the surface of the water-filtering cover 205 and supported by the sealing edge 209. The top cover 204 is threaded to the inner wall of the fixed bottom cover 203 so that the fixed top cover 204, together with the sealing edge 209, restricts the water filter cover 205 to the inner wall of the fixed bottom cover 203. The top of the water filter cover 205 has multiple water filter holes 206, and the surface of the water filter cover 205 has multiple water filter grooves 207. The top of the fixed top cover 204 has multiple water inlet notches 208. The bottom of the sealing edge 209 is provided with a sealing ring 210, and the sealing ring 210 is tightly fitted to the inner wall of the fixed bottom cover 203 so that the rainwater entering the rain inlet 201 can only enter the interior of the water filter cover 205 through the water filter holes 206 or the water filter grooves 207, thereby playing a filtering role.

[0033] When the above structure is in use, the rainwater is filtered by the first filter screen 202, so that impurities such as leaves are filtered out. The rainwater entering the rain inlet 201 will pass through the filter holes 206 and the filter groove 207 and pass through the filter cover 205 to further filter the rainwater.

[0034] By setting up the filter cover 205, rainwater can only enter the interior of the filter cover 205 after being filtered through the filter holes 206 and the filter tank 207, thus filtering out large impurities in advance and reducing the workload of the anti-clogging components.

[0035] An anti-clogging component is installed in the middle of the outer cylinder 1 to prevent silt and sand from accumulating and hardening. The anti-clogging component includes a water inlet funnel 301 located directly below the rain inlet 201. An upper cover 303 is fixedly installed on the inner wall of the water inlet funnel 301, and a lower cover 304 is fixedly installed at the bottom of the upper cover 303. A reduction motor 305 is fixedly installed between the upper cover 303 and the lower cover 304, and a silt scraper 306 is fixedly installed on the output shaft of the reduction motor 305. The silt scraper 306 movably passes through the lower cover 304 and is rotatably connected to the inner wall of the water inlet funnel 301. The bottom is designed so that the silt and sand accumulated at the bottom of the water inlet funnel 301 can be driven by the rotation of the silt scraper 306 and discharged downward with the rainwater. The inner wall of the water inlet funnel 301 is fixedly installed with a second filter screen 302, and the upper cover 303 is fixedly installed in the middle of the second filter screen 302. The silt scraper 306 is designed to avoid the cylindrical structure with a water channel so that the silt scraper 306 does not affect the normal flow of rainwater when it is working. The bottom of the lower cover 304 is provided with a detection probe 307, and the detection probe 307 is a water immersion sensor probe.

[0036] When the above structure is in use, rainwater entering the filter cover 205 continues to drip downwards through the drainage hole in the middle of the fixed bottom cover 203, and drips into the water inlet funnel 301. The rainwater is filtered again by the second filter screen 302 in the water inlet funnel 301, which further plays a filtering role. When the rainwater enters the bottom of the water inlet funnel 301 and is detected by the detection probe 307, the detection probe 307 sends a signal to the reduction motor 305, which causes the reduction motor 305 to work and drive the mud scraper 306 to rotate at the bottom of the water inlet funnel 301. This scrapes the mud on the inner wall of the bottom of the water inlet funnel 301, preventing the mud from hardening in the narrow space at the bottom of the inner wall of the water inlet funnel 301. The mud entering the water inlet funnel 301 is stirred by the mud scraper 306 and washed away with the rainwater, thus ensuring the smooth flow of water out of the bottom of the water inlet funnel 301.

[0037] A metering component for measuring rainwater is installed at the bottom of the outer cylinder 1. The metering component includes a base 407 threaded to the bottom of the inner wall of the outer cylinder 1. A tipping bucket bracket 401 is fixedly installed on the top of the base 407. An upper tipping bucket 402 is rotatably connected to the top of the tipping bucket bracket 401. A stepped controlled-release water injection funnel 403 is fixedly installed in the middle of the bottom position of the tipping bucket bracket 401 corresponding to the bottom position of the upper tipping bucket 402. A metering tipping bucket 404 and a counting tipping bucket 405 are rotatably connected in the middle of the bottom position of the tipping bucket bracket 401 corresponding to the bottom position of the stepped controlled-release water injection funnel 403. The metering tipping bucket 404 is located on top of the counting tipping bucket 405. A level 406 is fixedly installed at one end of the bottom of the tipping bucket bracket 401. A drainage bucket 408 is fixedly embedded in the bottom of the base 407 corresponding to the position of the counting tipping bucket 405.

[0038] In use, the above structure allows rainwater to enter the upper tipping bucket 402 and, as the upper tipping bucket 402 rotates, fall from both ends into the stepped controlled-release water injection funnel 403 to converge, thus stabilizing the flow rate of the rainwater. Then, the rainwater enters the metering tipping bucket 404 through the bottom of the stepped controlled-release water injection funnel 403 and falls from both ends into the counting tipping bucket 405 as the metering tipping bucket 404 rotates. At this time, the rainwater is metered by the rotation of the metering tipping bucket 404 and the counting tipping bucket 405 in conjunction with the sensor. This part is prior art and will not be described in detail in this patent. Finally, the rainwater is discharged downward through the drainage bucket 408.

[0039] Working principle: When in use, the utility model collects rainwater in the rain inlet 201 and filters it through the first filter screen 202, so that impurities such as leaves are filtered out. The rainwater entering the rain inlet 201 will pass through the filter holes 206 and the filter tank 207 and pass through the filter cover 205, which further filters the rainwater.

[0040] By setting the fixed top cover 204 and the fixed bottom cover 203 to be threadedly connected, the fixed top cover 204 can cooperate with the sealing edge 209 to lock the water filter cover 205 on the inner wall of the rain inlet 201, and the sealing edge 209 can press the sealing ring 210 against the inner wall of the fixed bottom cover 203, so that rainwater can only enter the interior of the water filter cover 205 after being filtered through the water filter hole 206 and the water filter tank 207, thus filtering out large impurities in advance and reducing the workload of the anti-clogging components;

[0041] Rainwater entering the filter cover 205 continues to drip downwards through the drain hole in the middle of the fixed bottom cover 203, and drips into the inlet funnel 301. The rainwater is filtered again by the second filter screen 302 in the inlet funnel 301, further enhancing the filtration effect. When rainwater enters the bottom of the inlet funnel 301 and is detected by the detection probe 307, the detection probe 307 sends a signal to the reduction motor 305, causing the reduction motor 305 to work and drive the mud scraper 306 to rotate at the bottom of the inlet funnel 301. This scrapes the mud on the inner wall of the bottom of the inlet funnel 301, preventing the mud from hardening in the narrow space at the bottom of the inlet funnel 301. The mud entering the inlet funnel 301 is stirred by the mud scraper 306 and washed away with the rainwater, thus ensuring the smooth flow of water out of the bottom of the inlet funnel 301.

[0042] When rainwater flows out from the bottom of the inlet funnel 301, it enters the top tipping funnel 402 and, as the top tipping funnel 402 rotates, falls from both ends into the stepped controlled-release water injection funnel 403 to converge, thus stabilizing the flow rate of the rainwater. Then, the rainwater enters the metering tipping funnel 404 through the bottom of the stepped controlled-release water injection funnel 403 and falls from both ends into the counting tipping funnel 405 as the metering tipping funnel 404 rotates. At this time, the rainwater is metered by the rotation of the metering tipping funnel 404 and the counting tipping funnel 405 in conjunction with the sensor. This part is prior art and will not be described in detail in this patent. Finally, the rainwater is discharged downward through the drain hopper 408.
