Description

Technical Field

[0001] The present invention belongs to the technical field of hydrological detection, and particularly relates to a double tipping bucket rain gauge for anti-blocking and blockage detection and an auxiliary device. Background Art

[0002] A rain gauge is a conventional meteorological detection instrument that can be used to detect and measure rainfall and rainfall intensity. Currently, commonly used rain gauges include tipping bucket rain gauges, weighing rain gauges, siphon rain gauges, etc. It is mainly used in the fields of hydrology, meteorology, environment, agriculture, etc., such as for flood warning, water resource management, irrigation management, agricultural disaster prevention, etc.

[0003] The rain gauge device is installed outdoors. A rain collector is provided at the upper end of the rain gauge and is equipped with a filter screen. However, due to the presence of a large amount of impurities such as leaves, small animals, sediment, and dust outdoors, even the rainwater filtered through the filter screen will still become blocked. Especially in the northwestern region, fine sediment and dust are also likely to enter the funnel and cause blockage, which in turn affects the collection of rain gauge data, resulting in inaccurate collection of rainfall data. At the same time, the blockage problem of the rain gauge cannot be detected in a timely and efficient manner, which will increase the maintenance cost and maintenance time. Therefore, it is necessary to effectively detect whether the rain gauge is malfunctioning and blocked to improve the reliability and accuracy of detection. Summary of the Invention

[0004] To solve the above problems, the present invention aims to provide a brand-new rain gauge that effectively prevents the rain gauge from being blocked and automatically diagnoses the blockage situation. It solves the problem that traditional rain gauges cannot efficiently detect blockages, accurately determines the blockage point, improves the maintenance and repair efficiency, and is widely used in hydrological stations, meteorological stations, intelligent irrigation areas, urban drainage systems, etc. At the same time, the setting of the three-stage filter screen effectively prevents blockages and timely and accurately detects the precipitation. It can detect and alarm in a timely manner for the abnormal blockage situation, transmit data remotely in a timely manner, improve work efficiency, and improve the reliability and accuracy of detection.

[0005] To achieve the above object, the present invention provides the following technical solutions: A double tipping bucket rain gauge for anti-blocking and blockage detection, comprising an outer cylinder, a bracket, and a base. The outer cylinder is located outside the base; the bracket is fixed on the base; a rain collector is provided above the bracket. A funnel, an upper tipping bucket, a collecting funnel, a measuring tipping bucket, and a counting tipping bucket are sequentially arranged on the bracket from top to bottom. A first reed switch is provided on the bracket, and a first magnet is provided on the upper tipping bucket. The first magnet cooperates with the first reed switch to achieve counting. A second reed switch is provided on the bracket, and a second magnet is provided on the counting tipping bucket. The second magnet cooperates with the second reed switch to achieve counting; the double tipping bucket rain gauge realizes more accurate measurement and detection through the cooperation of two magnets and reed switches for counting.

[0006] A first anti-blocking net is provided inside the rain collector; a mesh cover filter column is provided at the center of the bottom of the rain collector; a second anti-blocking net is arranged in the funnel; triple filtration is carried out to achieve multiple effective filtrations of rainwater, and the purified rainwater enters the tipping bucket for counting to avoid blockage.

[0007] Two through holes are symmetrically provided at the bottom of the rain collector and are arranged on both sides of the filter column; a detection probe is provided in the through hole, and an insulator is arranged outside the detection probe (for aesthetics and to reduce false detection); the bottom of the detection probe is connected to the controller through a wire; the wire is a two-core spring wire, one end of the spring wire is connected to the tail of the detection probe, the other end of the spring wire is connected to a male DC plug, the male DC plug is connected to a female DC plug, and the female DC plug, the first reed switch wiring, and the second reed switch wiring are jointly connected to an external aviation plug, and the aviation plug is connected to the controller; the blockage detection component of the present invention mainly uses a detection probe. When the rain collector is blocked, the accumulated rainwater will gradually rise and submerge the probe. Once the probe is submerged by water, the two probes are connected through the rainwater and form an electrical conduction path with the internal circuit. An electrical conduction path is formed through the rainwater connection to output a blockage alarm signal. Users make full use of the signals transmitted by the detection probe and the two reed switches to detect the operating state of the sensor, realize intelligent self-diagnosis of the sensor state, and timely discover and report abnormal information. The wire connection method is used, which is more convenient to connect, the structure is simple and less prone to errors. The contact between the detection probe and the controller is more reliable, and the detection result is more accurate. Moreover, the structural settings of the spring wire, DC plug, and aviation plug facilitate installation, disassembly, and maintenance.

[0008] The rain gauge is also provided with an auxiliary device, which includes an annular clamp, a spring lock, a support leg, a spring positioning pin, a damping hinge, and a joint fixed clamp seat. The annular clamp includes a left clamp and a right clamp. One end of the left clamp and the right clamp is connected through the damping hinge, and the other end of the left clamp and the right clamp is connected through the spring lock. A spring positioning pin and a joint fixed clamp seat are provided at the bottom of the annular clamp, and the bottom of the annular clamp is connected to the support leg. The auxiliary device is used in cooperation with the above-mentioned blockage detection component, which is convenient for the installation and disassembly of the entire rain gauge, conducive to maintenance, can be operated by a single person, and saves operation time. The auxiliary device can be used alone and recycled.

[0009] The rain gauge is also provided with a mounting frame, which includes an integrally formed base frame and a support frame. One side of the base frame is connected to the support frame, and the controller is placed obliquely on the support frame. The base frame is connected to the base. The structure of the mounting frame, on the one hand, facilitates the installation of the entire rain gauge and the controller, and is convenient for maintenance and repair. On the other hand, it is convenient to install and fix the outer cylinder and the base of the entire rain gauge on the site. If the rain gauge is directly installed on the site, there will be a problem of unstable installation affected by wind. The mounting frame of the present invention perfectly solves this problem.

[0010] Further, 3 spring positioning pins are evenly distributed, and 4 support legs are provided.

[0011] Further, the bottom of the support leg is provided with an anti-slip layer, and the inner side wall of the annular clamp is provided with an anti-slip layer. A good anti-slip effect is achieved.

[0012] Further, the detection probe is fixed to the rain receiver through a plugging detection screw, and one end of the spring wire is fixed to the bottom of the through hole of the rain receiver by using a wire twisting buckle. The above method is used to play a fixing role.

[0013] Further, a column is provided on the base frame. The column passes through the through hole provided in the base and is connected by screws, so that the base of the rain gauge is detachably and fixedly connected to the mounting frame. The base frame is provided with mounting holes, which is convenient for the fixed connection between the base frame and the installation environment.

[0014] Further, a solar panel is also provided on the support frame, and the solar panel is located above the controller. The controller is first arranged on the support frame, and then the solar panel is arranged. The solar panel can realize power supply.

[0015] Further, a baffle is also provided on the bracket. Positioning screws are respectively provided on both sides of the baffle. The first reed switch is located above one of the positioning screws. One side of the first reed switch is closely attached to the baffle, and the first reed switch is connected to the bracket through a bolt. Through the fixation of the baffle and the bolt, the reed switch can be more stably connected to the bracket, and compared with the installation method of the prior art, it is more concise and simple.

[0016] Further, the upper tipping bucket is provided with an opening, and a first magnet is provided at the opening. The first magnet is fixed to the opening through glue. A small amount of glue is squeezed into the bottom of the magnet, and the magnet is placed and pressed. After the glue solidifies, the gap between the magnet and the opening can be filled, so that the magnet can be stably arranged at the opening and is not easy to slide out. In the prior art, the magnet is directly pressed at the opening, but in actual use, after actual measurement, if it runs for a long time, the magnet has a risk of protruding from the fixing surface, and seriously, the magnet may be separated from the tipping bucket. Therefore, the above structure and installation technique can cleverly solve this problem.

[0017] Further, the diameter of the first magnet of the tipping bucket is 2 mm and the height is 4 mm. Every time the tipping bucket flips once, the magnet will approach the reed switch and cause it to close or open, thereby outputting an electrical pulse signal for judging the working state of the buffer tipping bucket. It is used to detect whether the rain gauge is operating normally and can also achieve one-time signal detection.

[0018] Further, the distance between the first magnet and the first reed switch is 2 mm. Keeping an appropriate distance between the magnet and the reed switch can weaken the influence of the magnetic force and ensure the accuracy of the device.

[0019] Further, the controller accesses the probe signals of the rain collector and the signals of the two reed switches. The controller comprehensively judges the degree of rainwater accumulation based on the resistance and capacitance values between the two probes of the rain collector, and then gives the degree of blockage of the rain collector. According to the counting difference between the two reed switches and the time difference between the triggering moments of the two reed switches being turned on, it judges the flipping flexibility of the tipping bucket and the metering tipping bucket, and determines whether there has been jamming or affecting the metering accuracy. According to the change trend of the time difference between the triggering moments of the two reed switches being turned on, the unobstructed situation of the collecting funnel can be judged and the degree of blockage can be given.

[0020] The present invention also discloses an auxiliary device for a rain gauge, which can be used alone. The auxiliary device includes an annular hoop, a spring lock, a support leg, a spring positioning pin, a damping hinge, and a joint fixed card seat. The annular hoop includes a left hoop and a right hoop. One end of the left hoop and the right hoop is connected by a damping hinge, and the other end of the left hoop and the right hoop is connected by the spring lock. The bottom of the annular hoop is provided with a spring positioning pin and a joint fixed card seat, and the bottom of the annular hoop is connected with the support leg. This auxiliary device can be used alone to realize more convenient installation and disassembly of the rain gauge. Beneficial effects

[0021] Effectively prevent blockage. The structure with three-stage filtration can effectively isolate impurities such as branches, leaves, and dust, avoid causing blockage, and reduce risks.

[0022] The setting of the blockage detection structure of the present invention makes the contact between the detection probe and the controller more reliable and the detection result more accurate. At the same time, the connection method of the spring wire, DC plug, and aviation plug makes the operation of connection and disassembly more convenient and is easy to install and maintain.

[0023] Timely warning. The controller can detect the blockage situation in time and send out an alarm signal to ensure that users can take measures to clean up in time, so as to keep the sensor in a normal working state. At the same time, it can accurately warn the blocked part, which is convenient for timely handling of the blockage problem, improving the accuracy and reliability of detection.

[0024] The setting of the double tipping buckets improves the accuracy of rainfall detection, reduces the false detection phenomenon in the non-rainfall state, and ensures the precision and reliability of detection.

[0025] Intelligent detection, the structural setting of the probe and the controller. When the accumulated rainwater gradually rises and submerges the probe, a conductive path is formed through the connection of the rainwater, and a blockage alarm signal is output. Users can discover and handle the blockage problem in time, avoiding long-term data loss or inaccuracy. According to the counting situation of two reed switches, the jamming situations of the upper tipping bucket, the metering tipping bucket, and the blockage situation of the collecting funnel are judged.

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Embodiment

[0035] A double tipping bucket rain gauge for anti-blocking and blockage detection as shown in Figures 1 - 8 includes an outer cylinder 22, a bracket 26, and a base 23. The outer cylinder 22 is located outside the base 23; the bracket 26 is fixed on the base 23; above the bracket 26 is provided a rain collector 1, and on the bracket 26, a funnel 3, an upper tipping bucket 6, a collecting funnel 7, a measuring tipping bucket 11, and a counting tipping bucket 8 are arranged in sequence from top to bottom. Below the rain collector 1 is provided the funnel 3, below the funnel 3 is provided the upper tipping bucket 6, below the upper tipping bucket 6 is provided the collecting funnel 7, below the collecting funnel 7 is provided the measuring tipping bucket 11, and below the measuring tipping bucket 11 is provided the counting tipping bucket 8. On the bracket 26 is provided a first reed switch 5, and on the upper tipping bucket 6 is provided a first permanent magnet 4. The first permanent magnet 4 and the first reed switch 5 cooperate to achieve counting. On the bracket 26 is provided a second reed switch 10, and on the counting tipping bucket 8 is provided a second permanent magnet. The second permanent magnet and the second reed switch 10 cooperate to achieve counting; the double tipping bucket rain gauge respectively achieves counting through the cooperation of two permanent magnets and reed switches, realizing more accurate measurement and detection.

[0036] Among them, a first anti-blocking net 15 is arranged inside the rain collector 1; at the center of the bottom of the rain collector 1 is provided a mesh cover filtering column 2; a second anti-blocking net 14 is arranged in the funnel 3. Three-stage filtering is adopted to achieve multiple effective filtrations of rainwater. The purified rainwater enters the tipping bucket for counting, avoiding blockage. The rainwater is filtered by the first anti-blocking net of the rain collector to filter out large impurities, and then passes through the mesh cover filtering column for secondary filtration. After filtration, it enters the funnel, and then passes through the second anti-blocking net of the funnel again. After purifying the water quality, it enters the upper tipping bucket, then enters the collecting funnel, enters the measuring tipping bucket and the counting tipping bucket to achieve rain gauge detection, and then flows out of the rain gauge cylinder. The structural setting of three-stage filtering can effectively isolate impurities such as branches and leaves, avoid blockage, and reduce risks.

[0037] Two through holes are symmetrically provided at the bottom of the rain collector 1 and are arranged on both sides of the filter column 2; detection probes 35 are provided in the through holes, and an insulator is provided outside the detection probes 35 (the insulator is arranged on the outer surface to prevent false measurement of data when rainwater contacts the side surface, so the insulator can effectively reduce false measurement, and at the same time, it has a beautiful appearance); the bottom of the detection probe 35 is connected to the controller 25 through a wire; the wire is a two-core spring wire 17, and the tail of the detection probe 35 is connected to one end of the spring wire 17 (the spring wire 17 is fixed to the bottom of the through hole of the rain collector using a wire twist buckle), the other end of the spring wire 17 is connected to a male DC plug 18, the male DC plug 18 is connected to a female DC plug, the female DC plug, the first reed switch wiring, and the second reed switch wiring are jointly connected to an external aviation plug 20, and the aviation plug 20 is connected to the controller 25. The detection probe is fixed on the rain collector 1 through a plugging detection screw 16, and one end of the spring wire 17 is fixed to the bottom of the through hole of the rain collector 1 using a wire twist buckle. The plugging detection component of the present invention mainly uses detection probes. When the rain collector is blocked, once the probe is flooded with water, the two probes are connected through rainwater and form an electrical conduction path with the internal circuit, outputting a blockage alarm signal. The user makes full use of the signals transmitted by the detection probes and the two reed switch wirings to detect the operating state of the rain gauge sensor, realize the intelligent self-diagnosis of the state of the rain gauge sensor, and timely discover and report abnormal information. The wire connection method is adopted, which is convenient to connect, has a simple structure and is less prone to errors. The contact between the detection probe and the controller is more reliable, and the detection result is more accurate. Moreover, the structural settings of the spring wire, DC plug, and aviation plug are convenient for installation, disassembly, maintenance, and repair.

[0038] As Figures 4 - 8As shown in the figure, the rain gauge is also provided with an auxiliary device, which includes an annular hoop 27, a spring lock 28, a support leg 29, a spring positioning pin 30, a damping hinge 31, and a joint fixing clamp seat 32. The annular hoop 27 includes a left hoop and a right hoop. One end of the left hoop and the right hoop is connected by a damping hinge 31, and the other end of the left hoop and the right hoop is connected by a spring lock 28. A support leg 29 is provided at the bottom of the annular hoop 27, and a joint fixing clamp seat 32 and a spring positioning pin 30 are also provided at the bottom of the annular hoop 27. The auxiliary device is used in cooperation with the above-mentioned blockage detection component, which is convenient for the installation and disassembly of the entire rain gauge, conducive to maintenance and repair, can be operated by a single person, saves operation time, and the auxiliary device can be used alone. There are 3 spring positioning pins 30 evenly distributed, and 4 support legs 29 are provided. A support leg anti-slip layer 34 is provided at the bottom of the support leg 29, and a hoop anti-slip layer 33 is provided on the inner side wall of the annular hoop 27. A good anti-slip effect is achieved. When in use, after the rain gauge is taken out of the packing box on site, the auxiliary device is opened (when the spring lock is opened), the annular hoop is fitted around the outside of the outer cylinder. Under the action of the damping hinge, the entire annular hoop is not easy to move and is placed relatively stably. Then the rain gauge cylinder is lifted to a height where the bottom exceeds the spring positioning pin, the spring positioning pin is opened, so that the outer cylinder falls on the spring positioning pin to limit the height of the rain gauge cylinder, and then the spring lock is locked. After the hoop clamps the rain gauge cylinder, the positioning spring pin is reset, and the spring wire docking head is rotated and loosened and then snapped into the joint fixing groove. The overall movement of the outer cylinder is realized, and all the installation and disassembly steps can be operated by a single person, and the installation and disassembly can be completed without the cooperation of multiple people.

[0039] The rain gauge is also provided with a mounting bracket 24. The mounting bracket 24 includes a bottom bracket and a support bracket integrally formed. One side of the bottom bracket is connected to the support bracket, and the controller 25 is placed obliquely on the support bracket. The bottom bracket is connected to the base 23. There is a column on the bottom bracket, and the column passes through the through hole provided in the base 23 and is connected by screws, so that the base of the rain gauge and the mounting bracket are detachably and fixedly connected. There are mounting holes on the bottom bracket, which is convenient for the fixed connection between the bottom bracket and the ground. There is also a solar panel on the support bracket, and the solar panel is located above the controller. The controller is set on the support bracket first, and then the solar panel is set. The solar panel can supply power. The mounting bracket is mainly used for installing the entire rain gauge and the controller. Among them, the bottom bracket and the base are fixedly connected in a detachable manner, and the external controller is set on the support bracket. At the same time, there is also a solar panel on the support bracket. The controller is set on the support bracket first, and then the solar panel is set. The solar panel can supply power. The structure is reasonably set, the installation is more convenient and stable, and the detection data of the rain gauge is ensured to be more accurate. The structural setting of the mounting bracket, on the one hand, is convenient for the installation of the entire rain gauge and the controller, and is conducive to maintenance and repair. On the other hand, it is convenient for the installation and fixation of the outer cylinder and the base of the entire rain gauge on the site. If the rain gauge is directly installed on the site, there will be a problem that the installation is unstable under the influence of wind. The mounting bracket of the present invention perfectly solves this problem.

[0040] A baffle is provided on the bracket 26. Positioning screws 13 are respectively provided on both sides of the baffle. The first reed switch 5 is located above one of the positioning screws, and one side of the first reed switch 5 is closely attached to the baffle. The first reed switch 5 is connected to the bracket 26 by a bolt. Through the fixation of the baffle and the bolt, the more stable connection of the reed switch on the bracket can be realized, and compared with the installation method of the prior art, it is more concise and simple.

[0041] The upper tipping bucket 6 is provided with an opening, and a first magnet 4 is provided at the opening. The opening size is slightly larger than the first magnet 4, and the first magnet 4 is fixed to the opening with glue. A small amount of glue is squeezed into the bottom of the magnet, and the magnet is placed and pressed. After the glue solidifies, the gap between the magnet and the opening can be filled, so that the magnet can be stably set at the opening and is not easy to slide out. In the prior art, the magnet is directly pressed at the opening, but in actual use, after actual measurement, if it runs for a long time, there is a risk that the magnet protrudes from the fixing surface, and in serious cases, the magnet may break away from the tipping bucket. Therefore, the above structure and installation technique can cleverly solve this problem.

[0042] The first magnet 4 of the upper tipping bucket has a diameter of 2 mm and a height of 4 mm. Every time the tipping bucket flips once, the magnet will approach the reed switch and make it close or open, thereby outputting an electrical pulse signal for judging the working state of the buffer tipping bucket. On the one hand, it can be used to detect whether the rain gauge is operating normally. On the other hand, a signal detection can also be realized.

[0043] In this embodiment, a metering tipping bucket 11 is provided below the counting tipping bucket 8, a second reed switch 10 is provided on the bracket 26, and a capacity adjustment screw 12 is provided. There is also a spirit level 9 on the base 23 to adjust whether the rain gauge is horizontal; a waterproof joint 19 is provided on the base 23, and the wire passes through the waterproof joint 19 to protect the circuit (the joint plays a protective role and can also control the outlet length to prevent the internal welding point from being pulled and the circuit from being disconnected); the red and black terminal posts 21 provided on the bracket 26 are used to connect the power supply or output signals. Embodiment

[0044] The distance between the first magnet and the first reed switch is 2 mm. Keeping an appropriate distance between the magnet and the reed switch can weaken the influence of the magnetic force and ensure the accuracy of the device.

[0045] As shown in the following table: The distance between the magnet and the reed switch is adjusted to 0 mm, 1 mm, and 2 mm respectively to simulate three kinds of rainfall intensities of large, medium, and small, and check the closing time of the reed switch when the tipping bucket flips. After actual measurement, when the distance between the magnet and the reed switch is 2 mm, when the tipping bucket flips to the left and right, the average closing times of the reed switch are 15 ms and 28 ms respectively, and at this time, the balance between the suction force and the distance between the magnet and the reed switch is achieved.

[0046] Distance for raising the reed switch Rain intensity Width of the artery when the tipping bucket turns right Width of the artery when the tipping bucket turns left 0 2.5 36 101 0 3.8 34 96 0 6 35 94 1 2.5 29 70 1 3.8 28 70 1 6 29 70 2 2.5 14 28 2 3.8 16 32 2 6 13 25 The above are only the preferred technical solutions of the present invention. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
