Abstract
Description
Technical Field
[0001] This utility model relates to the field of geological disaster prevention and control technology, and in particular to a rainfall monitoring device for geological disaster prevention and control. Background Technology
[0002] Heavy rainfall is one of the main factors causing natural disasters such as landslides, mudslides, and floods. The application of real-time rainfall monitoring devices is crucial for effectively preventing these disasters. By accurately measuring rainfall, high-risk areas can be identified in advance, allowing for necessary preventative measures to be taken, thereby avoiding or mitigating the impact of disasters.
[0003] In outdoor rainfall monitoring devices, filters play a crucial role in ensuring measurement accuracy and long-term stable operation. However, traditional rainfall monitoring equipment often only has simple water collection inlets and lacks an effective filtration mechanism. This allows impurities such as fallen leaves, branches, and dust in rainwater to easily enter the measurement system, thus affecting the accurate measurement of precipitation.
[0004] Specifically, impurities can obstruct rainwater from flowing into the measuring container or add extra weight or volume during measurement, thus interfering with the results. Furthermore, long-term accumulation of impurities can lead to wear or corrosion of internal components, shortening the equipment's lifespan and increasing the cost of maintenance and replacement parts. For monitoring devices located in remote areas, regular manual cleaning and maintenance not only increases costs and workload but is also more difficult to implement due to geographical limitations. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings, the technical problem of this utility model is to provide a rainfall monitoring device for geological disaster prevention.
[0006] The technical implementation scheme of this utility model is as follows: A rainfall monitoring device for geological disaster prevention includes a shell, a base, a filter screen, a connecting plate, a funnel, a tilting bucket, a bracket, a sensor head, a sensor, a rotating shaft, and a cleaning component. The bottom of the shell is connected to the base, and water outlets are opened on both sides of the middle of the base. The upper and lower ends of the shell are open. A filter screen is connected to the upper port of the shell. A connecting plate is symmetrically connected to the upper side of the shell. A funnel is connected between the connecting plates. A bracket located inside the shell is connected to the top of the base. A rotating shaft is rotatably connected to the lower side of the bracket. Two tilting buckets are connected to the middle of the rotating shaft. The openings of the two tilting buckets are aligned with the two water outlets. Sensor heads are installed at the two front corners of the two tilting buckets. Sensors are symmetrically installed on the lower front side of the bracket. Both the sensors and the sensor heads are electrically connected to a remote control system.
[0007] As a preferred technical solution of this utility model, the cleaning component includes a scraper, a rotating rod, a gear ring, a drive shaft, a pinion, a ratchet, and a pulley assembly. The gear ring is rotatably connected to the outer side of the upper part of the funnel, and the rotating rod is connected to the middle of the gear ring. The upper end of the rotating rod passes through the top of the filter screen and is connected to the scraper. The scraper is in close contact with the top surface of the filter screen. The pinion is connected to the front side of the upper part of the funnel through a rotating shaft. The pinion meshes with the gear ring. The drive shaft is rotatably connected to the upper part of the funnel below the pinion. The ratchet is connected to the drive shaft and meshes with the pinion. A pulley assembly for transmitting power is provided between the front end of the drive shaft and the front end of the rotating shaft.
[0008] As a preferred technical solution of this utility model, the ratchet gear consists of a ratchet wheel and a pawl, and its main function is to convert reciprocating motion into unidirectional stepping motion.
[0009] As a preferred technical solution of this utility model, the scraper body consists of three arc-shaped plates with the arc surfaces facing the same direction.
[0010] As a preferred technical solution of this utility model, it also includes a collection hopper and a throttling tube. The collection hopper is connected to the upper side of the bracket and is located below the funnel. The lower end of the collection hopper is connected to a throttling tube that communicates with it.
[0011] As a preferred technical solution of this utility model, it also includes a positioning plate, which is connected to the lower front side of the support and is in contact with the two tilting buckets.
[0012] Beneficial effects: 1. The top filter design effectively intercepts fallen leaves and other larger impurities, ensuring that only pure rainwater enters the measuring system. In addition, a scraper is set up to automatically remove impurities from the filter screen and prevent it from clogging. This feature significantly reduces the need for manual maintenance and ensures long-term stable operation.
[0013] 2. Through the coordinated operation of the tilting bucket, the sensing head, and the sensor, this device can accurately quantify precipitation. Each time the tilting bucket tilts, the sensing head triggers the sensor to count, thus achieving high-precision measurement of precipitation. This design not only improves the accuracy of the measurement but also enhances the stability and reliability of the system.
[0014] 3. The design of the pulley assembly and ratchet gear transmits the power of the tilting bucket to the scraper, ensuring that the scraper rotates in only one direction, cleaning the filter screen at the most effective angle, reducing unnecessary energy consumption, and ensuring that the scraper achieves the best cleaning effect in each operation, extending the service life of the filter screen and further reducing maintenance costs.

Detailed Implementation
[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0021] Example: A rainfall monitoring device for geological disaster prevention, such as... Figures 1-4 As shown, it includes a housing 1, a base 2, a filter screen 4, a connecting plate 7, a funnel 8, a tilting bucket 13, a bracket 14, a sensor head 16, a sensor 17, a rotating shaft 18, and cleaning components. The bottom of the housing 1 is connected to the base 2, which is connected to it. The base 2 has water outlets 3 on both sides of the middle of its middle section. The two water outlets 3 are arranged in an outwardly sloping V-shape. The top and bottom of the housing 1 are open. The filter screen 4 is connected to the upper port of the housing 1. The connecting plates 7 are symmetrically welded to the upper side of the inside of the housing 1. The funnel 8 is connected between the connecting plates 7. The top of the base 2 is connected to... A bracket 14 is located inside the outer casing 1. A rotating shaft 18 is rotatably connected to the lower side of the bracket 14. Two tilting buckets 13 are connected to the middle of the rotating shaft 18. The two tilting buckets 13 are connected to each other. The openings of the two tilting buckets 13 are aligned with the two water outlets 3 respectively. Sensors 16 are bolted to the left and right corners of the front side of the two tilting buckets 13. Sensors 17 are bolted to the left and right sides of the lower front side of the bracket 14. Both the sensors 17 and the sensors 16 are electrically connected to the remote control system. The two work together to calculate the number of times the tilting buckets 13 are tilted.
[0022] like Figures 1-3As shown, the cleaning assembly includes a scraper 5, a rotating rod 6, a gear ring 9, a drive shaft 91, a pinion 92, a ratchet 10, and a pulley set 11. The gear ring 9 is rotatably connected to the upper outer side of the funnel 8. The rotating rod 6 is welded to the middle of the gear ring 9. The upper end of the rotating rod 6 passes through the top of the filter screen 4 and is connected to the scraper 5. The scraper 5 is in close contact with the top surface of the filter screen 4. The main body of the scraper 5 consists of three arc-shaped plates with the arc surfaces facing the same direction. By rotating, it can effectively scrape the impurities on the filter screen 4 outward. The upper front side of the funnel 8 is connected to the pinion 92 through a rotating shaft. The pinion 92 meshes with the gear ring 9. The drive shaft 91 is rotatably connected to the upper part of the funnel 8 below the pinion 92. The ratchet 10 is connected to the drive shaft 91 and meshes with the pinion 92. The ratchet 10 consists of a ratchet and a pawl. Its main function is to convert reciprocating motion into unidirectional stepping motion. A pulley set 11 for transmitting power is provided between the front end of the drive shaft 91 and the front end of the rotating shaft 18.
[0023] like Figures 2-3 As shown, it also includes a collection hopper 12 and a throttling pipe 15. The collection hopper 12 is connected to the upper side of the bracket 14. The collection hopper 12 is located below the funnel 8. The lower end of the collection hopper 12 is connected to a throttling pipe 15 for controlling the flow rate of rainwater.
[0024] like Figure 4 As shown, it also includes a positioning plate 19. The positioning plate 19 is welded to the lower front side of the bracket 14. The positioning plate 19 contacts and cooperates with the two tilting buckets 13. Each time the two tilting buckets 13 tilt and pour water, they will contact the positioning plate 19. The positioning plate 19 is used to limit the rotation angle of the tilting buckets 13 to ensure that the two tilting buckets 13 can form a left-right reciprocating motion.
[0025] This device is installed outdoors. When it rains, rainwater is filtered through the filter screen 4 and enters the funnel 8. The filter screen 4 effectively filters out fallen leaves and impurities mixed in with the rainwater, ensuring that only clean rainwater enters the funnel 8. The rainwater then falls through the funnel 8 into the collection hopper 12 and flows at a constant speed into the tilting hopper 13 on the lower right side through the throttling effect of the throttling tube 15. During this process, when the tilting hopper 13 is full of rainwater, it will swing to the right under the action of gravity, causing the two tilting hoppers 13 to tilt and drive the rotating shaft 18 to rotate in the forward direction. At this time, the rainwater in the right tilting hopper 13 will be poured out to the outlet 3 and flow out of the base 2 along the inclined surface of the outlet 3. After that, the left tilting hopper 13 aligns with the throttling tube 15, ready to receive new rainwater. Each time it tilts, the sensor head 16 on the tilting hopper 13 will rotate with the rotating shaft 18. The sensor 17 can detect the movement of the sensor head 16 and count the number of tilts accordingly. These data will be quantified into precipitation by the data processing unit and transmitted to the remote operating system for further analysis and monitoring. When the left tipping bucket 13 is full of rainwater, both tipping buckets 13 will tip to the left under the action of gravity, causing the rotating shaft 18 to rotate in the opposite direction. This process will repeat the above operation to achieve reciprocating motion.
[0026] It is worth noting that when the rotating shaft 18 rotates in the forward direction, it drives the transmission shaft 91 and the ratchet 10 to rotate via the pulley assembly 11. The ratchet 10 consists of a ratchet and a pawl. The power source drives the pawl to insert into the tooth groove of the ratchet, pushing the ratchet to rotate at a certain angle, which in turn drives the pinion 92 and the gear ring 9 to rotate. The rotation of the gear ring 9 drives the rotating rod 6 and the scraper 5 to rotate. The scraper 5 then scrapes the impurities on the filter screen outward, preventing the filter screen 4 from clogging. When the rotating shaft 18 rotates in the reverse direction, the pulley assembly 11 drives the transmission shaft 91 to rotate in the reverse direction, but the anti-reverse pawl in the ratchet 10 prevents the ratchet from rotating in the reverse direction, thus keeping the ratchet stationary. The pinion 92 is not driven to rotate, so the scraper 5 is also stationary. This design ensures that the scraper 5 can only rotate in the forward direction and cannot rotate in the reverse direction, ensuring that the impurities on the filter screen 4 are fully scraped off.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
