Automatic cleaning device for regional rain gauge sensors Technical Field
[0001] This utility model relates to the field of rainfall monitoring technology, and more specifically, to an automatic cleaning device for regional station rainfall sensors. Background Technology
[0002] Meteorological equipment such as unmanned automatic weather stations, regional stations, and highway weather stations use rain gauges with rain sensors to automatically measure rainfall during each rainfall event. These monitoring devices are installed in outdoor environments for data collection. Due to environmental factors, rain gauges are frequently clogged by dust, leaves, weeds, and other foreign objects, or insects may enter the rain gauge's internal monitoring channels, causing it to malfunction and requiring timely manual cleaning to restore normal operation. Because of the large number of weather stations and the complex environment, the failure rate due to rain gauge clogging is very high each year. Meteorological departments have explicit regulations requiring regular inspections and maintenance before, during, and at the end of the flood season. They also require immediate on-site handling of any abnormal rain gauge data detected. Furthermore, before any major rainfall event, it is necessary to check that all rain gauges are in normal working order to ensure accurate rainfall monitoring.
[0003] Because the number of rain gauges varies from unit to unit, ranging from dozens to hundreds or thousands, most of them are installed in remote rural areas. They are widely distributed and far away, requiring a lot of manpower and financial resources to solve. It also takes several days or even more than a month to complete the regular inspection and maintenance work. The traditional manual cleaning method not only consumes manpower and resources, but also cannot deal with sudden blockages in a timely manner, making it difficult to meet the needs of high-precision meteorological monitoring. Summary of the Invention
[0004] To overcome the shortcomings mentioned above, this utility model aims to provide an automatic cleaning device for regional station rain gauges, which can remotely control the cleaning of rain gauge cylinders, reducing the consumption of manpower and material resources.
[0005] An automatic cleaning device for regional station rain gauge sensors includes a base plate with a fixed rod fixedly connected to it. A first horizontal plate and a second horizontal plate are rotatably connected to the fixed rod. A moving mechanism is installed between the first and second horizontal plates, and a rain gauge is mounted on the moving mechanism. The moving mechanism includes a moving plate with two vertical plates fixedly connected to it. A rotating rod passes through and is rotatably connected to the two vertical plates. A fixed ring is fixedly connected to one end of the rotating rod, and the fixed ring is fixedly connected to the rain gauge. A first driving assembly is provided between the second horizontal plate and the fixed rod. The first driving assembly includes a first gear fixedly connected to the top of the fixed rod and a first servo motor mounted on the second horizontal plate. A first worm gear is fixedly connected to the output end of the first servo motor, and the first worm gear is drivingly connected to the first gear. A spray washing assembly is provided on the base plate, and an equipment box is mounted on the first horizontal plate. The equipment box contains a battery and a control panel, and the control panel is equipped with a communication module.
[0006] Furthermore, the movable plate slides on the fixed rod, a threaded rod passes through and is screwed onto the movable plate, a second drive assembly is installed between the movable plate and the rotating rod, and a third drive assembly is installed between the first horizontal plate and the threaded rod.
[0007] Furthermore, the second drive assembly includes a second gear fixed to the end of the rotating rod and a second servo motor mounted on the moving plate. The output end of the second servo motor is fixedly connected to a second worm gear, and the second worm gear is drivenly connected to the second gear.
[0008] Furthermore, a short rod is fixedly connected to the lower end of the threaded rod, and the third drive assembly includes a third gear fixedly connected to the short rod and a third servo motor mounted on the first horizontal plate. A third worm gear is fixedly connected to the output end of the third servo motor, and the third worm gear is connected to the third gear in a transmission connection.
[0009] Furthermore, a rainfall sensor is installed on the first horizontal plate.
[0010] Furthermore, a support frame is fixedly connected to the side wall of the first horizontal plate, and a monitoring camera is installed on the support frame.
[0011] Furthermore, the spray washing assembly includes a water storage tank fixed to the base plate, a mounting bracket fixed to the water storage tank, a high-pressure water pump mounted on the mounting bracket, the water inlet of the high-pressure water pump being connected to the water storage tank through a water pumping pipe, and the water outlet of the high-pressure water pump being connected to a spray nozzle through a water delivery pipe.
[0012] Furthermore, the outer diameter of the water storage cylinder is smaller than the inner diameter of the rain gauge.
[0013] Furthermore, a ring is fixed to the upper and lower end faces of the first and second horizontal plates on the fixing rod. The ring is located at the upper and lower end faces of the first and second horizontal plates and fits against the upper and lower end faces of the first and second horizontal plates.
[0014] Furthermore, the central axis of the water storage cylinder is parallel to the central axis of the fixing rod, the central axis of the fixing rod is parallel to the central axis of the rain gauge, and the distance between the central axis of the water storage cylinder and the central axis of the fixing rod is the same as the distance between the central axis of the fixing rod and the central axis of the rain gauge.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In this invention, the rain gauge is rotated above the spray washing assembly by the output of the first drive component. The spray washing assembly then cleans the lower half of the rain gauge. Next, the third servo motor rotates the third worm gear, which, in conjunction with the third gear, rotates the short rod and threaded rod, lifting the moving plate and raising the rain gauge. Then, the second servo motor rotates the second worm gear, which, in conjunction with the second gear, rotates the rotating rod, thus rotating the rain gauge and turning the upper half of the rain gauge towards the spray washing assembly. This allows the spray washing assembly to clean the upper half of the rain gauge. The forward and reverse drives of the third servo motor cause the rain gauge to repeatedly rise and fall, improving the cleaning effect inside the rain gauge and ensuring accurate rainfall monitoring. Raising and rotating the rain gauge so that its opening faces upwards allows for rainfall monitoring. Finally, the first drive component returns the rain gauge to its original position. The control panel is electrically connected to all devices and is equipped with a communication module, allowing for remote control via mobile phones or computers, reducing manpower and material costs.

[0023] 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.
[0024] Specific implementation examples:
[0025] As shown in Figures 1-4, the automatic cleaning device for the regional station rain gauge sensor includes a base plate 1, which is fixed to the ground by a fixing rod 2. A fixing rod 7 is fixedly connected to the base plate 1, and a first horizontal plate 3 and a second horizontal plate 14 are rotatably connected to the fixing rod 7. A ring 71 is fixedly connected to the upper and lower end faces of the first horizontal plate 3 and the second horizontal plate 14, thus restricting the vertical movement of the first horizontal plate 3 and the second horizontal plate 14. A moving mechanism 4 is installed between the first horizontal plate 3 and the second horizontal plate 14, and a rain gauge 5 is installed on the moving mechanism 4. The moving mechanism 4 includes a sliding mechanism... Moving plate 41, two vertical plates 42 are fixedly connected to it, and rotating rods 43 are rotatably connected through the two vertical plates 42. One end of the rotating rod 43 is fixedly connected to a fixing ring 44, which is fixedly connected to the peripheral wall of the rain gauge 5. A first drive assembly 6 is provided between the second horizontal plate 14 and the fixed rod 7. The first drive assembly 6 is used to make the first horizontal plate 3, the second horizontal plate 14, the moving mechanism 4 and the rain gauge 5 rotate relative to the fixed rod 7. A spray washing assembly 8 is provided on the base plate 1. An equipment box 9 is installed on the first horizontal plate 3. The equipment box 9 contains a battery and a control panel. The battery is electrically connected to the electrical equipment but does not provide power to it. The control panel is connected to each The equipment is electrically connected, and the control panel is equipped with a communication module, which in this embodiment is a mobile communication module, for remote control with a mobile phone or computer, such as the first drive assembly 6 and the spray washing assembly 8. The first drive assembly 6 includes a first gear 61 fixedly connected to the top of the fixed rod 7 and a first servo motor 62 mounted on the second horizontal plate 14. The output end of the first servo motor 62 is fixedly connected to a first worm gear 63, which is connected to the first gear 61 in a transmission connection. Since a moving mechanism 4 is installed between the first horizontal plate 3 and the second horizontal plate 14, the rain gauge 5 is mounted on the moving mechanism 4, and the first servo motor 62 is mounted on the second horizontal plate 14. 3. The second horizontal plate 14, the moving mechanism 4, and the rain gauge 5 form a rotating body. The first servo motor 62 is mounted on the rotating body. Since the second horizontal plate 14 and the first horizontal plate 3 are rotatably connected to the fixed rod 7, the first gear 61 and the fixed rod 7 are considered as a fixed body. The output of the first servo motor 62 causes the first worm gear 63 to rotate. The first worm gear 63 is connected to the first gear 61, so that the rotating body can rotate on the fixed body, rotating the rain gauge 5 above the spray washing assembly 8. The spray washing assembly 8 is then started to clean the rain gauge 5. There is no need for manual on-site cleaning of the rain gauge 5, thereby reducing the manpower and material costs of inspection and maintenance.
[0026] As shown in Figures 1-4, the movable plate 41 slides on the fixed rod 7. A second drive assembly 45 is installed between the movable plate 41 and the rotating rod 43. A threaded rod 47 passes through and is threadedly connected to the movable plate 41. A third drive assembly 46 is installed between the first horizontal plate 3 and the threaded rod 47. The second drive assembly 45 includes a second gear 451 fixedly connected to the end of the rotating rod 43 and a second servo motor 452 mounted on the movable plate 41. A second worm gear 453 is fixedly connected to the output end of the second servo motor 452. 3 is connected to the second gear 451 for transmission; the lower end of the threaded rod 47 is fixedly connected to a short rod 15, which is rotatably connected to the first horizontal plate 3. The third drive assembly 46 includes a third gear 461 fixedly connected to the short rod 15 (the short rod 15 is divided into two sections, and the third gear 461 is fixedly connected between the two sections of the short rod 15) and a third servo motor 462 mounted on the first horizontal plate 3. The output end of the third servo motor 462 is fixedly connected to a third worm gear 463, which is connected to the third gear 461 for transmission. An automatic cleaning program is set in the control panel via PLC. The automatic cleaning program is as follows: the output of the first drive component 6 rotates the rain gauge 5 above the spray washing component 8, and the spray washing component 8 cleans the lower half of the rain gauge 5. Then, the output of the third servo motor 462 rotates the third worm gear 463. The third worm gear 463 and the third gear 461 work together to rotate the short rod 15 and the threaded rod 47, lifting the moving plate 41 and raising the rain gauge 5. Finally, the output of the second servo motor 452 rotates the second worm gear 453. The second worm gear 453, in conjunction with the second gear 451, causes the rotating rod 43 to rotate, thereby rotating the rain gauge 5. This causes the interior of the upper part of the rain gauge 5 to face the spray washing assembly 8, enabling the spray washing assembly 8 to clean the interior of the upper part of the rain gauge 5. In conjunction with the forward and reverse drive of the third servo motor 462, the rain gauge 5 is repeatedly raised and lowered, improving the cleaning effect inside the rain gauge 5 and ensuring the accuracy of rainfall monitoring. The rain gauge 5 is raised and rotated so that its opening faces upward for rainfall monitoring. Then, the rain gauge 5 is returned to its original position by the drive of the first drive assembly 6.
[0027] As shown in Figures 1-4, a rainfall sensor 10 is installed on the first horizontal plate 3. The rainfall sensor 10 is connected to the control panel located in the equipment box 9 and transmits real-time rainfall information to the terminal so that the staff can know whether it is raining before cleaning the rain gauge 5. If it is raining, the rain gauge 5 cannot be cleaned at this time to avoid affecting the monitoring of rainfall data. The model of the rainfall sensor 10 is M92598.
[0028] As shown in Figures 1-4, a support frame 11 is fixedly connected to the side wall of the first horizontal plate 3. A monitoring camera 12 is installed on the support frame 11. The monitoring camera 12 is connected to the control panel, so that the real-time monitoring image can be transmitted to the terminal. With the monitoring camera 12, when the device is remotely controlled, it can respond to emergencies in a timely manner. It is also convenient to monitor the status of the rain gauge 5 in real time. The area station is usually equipped with a solar energy system, and the electrical equipment can also be connected to the solar power supply system for power supply.
[0029] As shown in Figures 1-4, the spray washing assembly 8 includes a water storage tank 81 fixedly connected to the base plate 1. A mounting bracket 82 is fixedly connected to the water storage tank 81. A high-pressure water pump 83 is installed on the mounting bracket 82. The inlet end of the high-pressure water pump 83 is connected to the water storage tank 81 through a water pumping pipe 84. The outlet end of the high-pressure water pump 83 is connected to a nozzle 86 through a water supply pipe 85. The water in the water storage tank 81 is sprayed out from the nozzle 86 through the output of the high-pressure water pump 83. The nozzle 86 is an axial flow solid cone nozzle.
[0030] As shown in Figures 1-4, the outer diameter of the water storage cylinder 81 is smaller than the inner diameter of the rain gauge 5, and the drain outlet and inlet on the water storage cylinder 81 are both located within the inner diameter range of the rain gauge 5, thus not affecting the raising and lowering of the rain gauge 5.
[0031] As shown in Figures 1-4, the diameter of the fixed rod 7 located below the first horizontal plate 3 is larger than the diameter of the other rods, which increases the contact area with the base plate 1 and improves the overall stability.
[0032] As shown in Figures 1-4, the central axis of the water storage cylinder 81 is parallel to the central axis of the fixed rod 7, and the central axis of the fixed rod 7 is parallel to the central axis of the rain gauge 5. The distance between the central axis of the water storage cylinder 81 and the central axis of the fixed rod 7 is the same as the distance between the central axis of the fixed rod 7 and the central axis of the rain gauge 5. In this way, after the rotating body rotates around the fixed rod 7 and the rain gauge 5 rotates to the top of the spray washing assembly 8, the rain gauge 5 can be lowered and fitted onto the outside of the spray washing assembly 8.
[0033] The working principle of the automatic cleaning device for regional station rain gauge sensors in this embodiment is as follows: During use, no on-site cleaning is required. Rainfall data transmitted from the rain sensor 10 to the control terminal (such as a mobile phone or computer) indicates rainfall conditions, or the monitoring camera 12 indicates rainfall. If no rainfall occurs, the cleaning program is initiated via the control panel, and the monitoring camera 12 is used to automatically clean the rain gauge cylinder 5. The output of the first drive component 6 rotates the rain gauge cylinder 5 above the spray cleaning component 8, cleaning the lower half of the rain gauge cylinder 5. The output of the third servo motor 462 rotates the third worm gear 463. The rod 463 and the third gear 461 work together to rotate the threaded rod 47, lifting the moving plate 41 and raising the rain gauge 5. Then, the output of the second servo motor 452 causes the second worm gear 453 to rotate. The second worm gear 453 works with the second gear 451 to rotate the rotating rod 43, thereby rotating the rain gauge 5. This causes the interior of the upper part of the rain gauge 5 to face the spray washing assembly 8, allowing the spray washing assembly 8 to clean the interior of the upper part of the rain gauge 5. The forward and reverse drive of the third servo motor 462 causes the rain gauge 5 to rise and fall repeatedly, improving the cleaning effect inside the rain gauge 5 and ensuring the accuracy of rainfall monitoring. The rain gauge can be cleaned remotely, reducing the consumption of manpower and material resources.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
