Description

Technical Field

[0001] This utility model relates to the technical field of flash flood warning and rainfall monitoring devices, specifically to a solar-powered flash flood warning and rainfall monitoring device. Background Technology

[0002] With the increasing frequency of global climate change and extreme weather events, the risk of mountain floods, especially flash floods, has significantly increased, posing a serious threat to people's lives and property. To improve the early warning capabilities for flash floods, rainfall monitoring, as a key basic data collection method, has become an important component of flash flood early warning systems. By monitoring changes in rainfall in real time and accurately, the occurrence of flash floods can be predicted in a timely manner, assisting relevant departments in taking effective prevention and emergency measures to minimize disaster losses.

[0003] Existing flash flood warning and rainfall monitoring devices typically employ fixed metering structures and battery-powered systems, which generally suffer from the following shortcomings: First, these devices are often exposed to harsh natural environments, especially during flash floods. The strong impact of the water flow and floating debris such as rocks and branches can easily damage the metering instruments and their auxiliary equipment, leading to malfunctions or even failures, thus affecting the continuity and accuracy of rainfall data. Second, the filtration systems of traditional devices are easily clogged by impurities and lack effective automatic cleaning functions, requiring frequent manual maintenance, increasing maintenance costs and difficulty. Furthermore, timely cleaning is difficult in emergencies, affecting monitoring effectiveness. Third, existing equipment largely relies on traditional battery power, which has limited battery life and makes long-term unattended operation difficult, restricting the widespread deployment and continuous operation of these monitoring devices.

[0004] Therefore, this solution proposes a solar-powered flash flood early warning and rainfall monitoring device to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a solar-powered flash flood early warning and rainfall monitoring device.

[0006] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: A solar-powered flash flood early warning rainfall monitoring device includes a raised base, a metering device installed on the top of the raised base, a protective cylinder surrounding the metering device on the top of the raised base, and a first electric telescopic rod installed at the center of the raised base to drive the metering device out of the top of the protective area of ​​the protective cylinder. The metering device includes an outer cylinder, a metering tube, and a liquid collection funnel. The outer cylinder is installed at the top of the first electric telescopic rod, the liquid collection funnel is installed at three-fifths of the height inside the outer cylinder, the metering tube is installed at the bottom center of the outer cylinder and its top end is connected to the bottom end of the liquid collection funnel, a filter screen is installed inside the outer cylinder directly above the liquid collection funnel, and a second electric telescopic rod is installed at the center of the outer cylinder to drive the filter screen out of the outer cylinder. A drive motor is installed at the top of the second electric telescopic rod, and the output shaft end of the drive motor is fixedly connected to the center of the filter screen.

[0007] Preferably, the second electric telescopic rod is located on the internal central axis of the metering tube, and the diameter of the second electric telescopic rod is smaller than the inner diameter of the liquid collection funnel's lower liquid hole.

[0008] Preferably, the internal metering space of the metering tube is an annular metering space formed between the inner wall of the metering tube and the outer wall of the electric telescopic rod.

[0009] Preferably, the outer surface of the filter screen is set as a conical shape.

[0010] Preferably, a housing is installed inside the raised base.

[0011] Preferably, a snap-fit ​​ring is installed at the lower end of the protective cylinder, and the snap-fit ​​ring is rotated and snapped onto the upper surface of the raised base.

[0012] Preferably, a mounting base is installed at the bottom of the raised base, and the mounting base is positioned on the ground by positioning bolts on the outer ring.

[0013] Preferably, an annular solar panel is installed on the outside of the outer cylinder, the diameter of which is smaller than the inner diameter of the protective cylinder, and a drain valve pipe connected to the bottom of the metering tube is installed at the bottom of the outer cylinder.

[0014] The beneficial effects of this utility model are reflected in: This solar-powered flash flood warning and rainfall monitoring device employs a clever mechanical structure design to achieve flexible retraction and self-protection of the meter and solar panel. During a flash flood, the meter and its associated annular solar panel can be automatically retracted into the protective cylinder via a first electric telescopic rod, effectively preventing direct impact and damage from strong water currents and floating debris, significantly improving the device's impact resistance and lifespan. Simultaneously, the protective cylinder itself features a rotatable locking ring structure, which rotates when encountering hard impurities such as rocks in the water, further dispersing and releasing the impact force, reducing the risk of equipment damage, and ensuring stable operation of the device in complex and harsh environments.

[0015] Furthermore, the internal filter of the meter, in conjunction with the second electric telescopic rod and drive motor, features an automatic probe and rapid rotation self-cleaning function. This design effectively removes impurities accumulated on the filter, preventing clogging that could lead to inaccurate rainwater collection or metering tube overflow, thus ensuring the accuracy and continuity of rainfall monitoring data. This automatic cleaning mechanism not only reduces the frequency and difficulty of manual maintenance but also enhances the device's intelligence and long-term reliability.

[0016] In summary, this rainfall monitoring device integrates mechanical protection, self-cleaning, and solar power, possessing excellent resistance to flash floods and consistently stable monitoring performance. Its flexible recovery and protection design effectively extends the equipment's lifespan, the automatic cleaning function ensures the accuracy of monitoring data, and the integration of solar panels enables unattended automatic monitoring. This significantly enhances the practical value and application prospects of flash flood early warning systems, providing an efficient, intelligent, and reliable technical means for disaster prevention and mitigation in mountainous areas.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0019] It should be noted that if the utility model embodiment involves directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0020] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.

[0021] Please refer to the instruction manual appendix. Figures 1-4 This utility model provides a solar-powered flash flood early warning rainfall monitoring device, including a raised base 1. A protective cylinder 4 surrounds a meter 3 on the top of the raised base 1. A locking ring 5 is located at the lower end of the protective cylinder 4, and the locking ring 5 is rotatably locked onto the upper surface of the raised base 1. This rotatable design allows the device to rotate when impacted by rocks or other impurities in the water during a flash flood, thus releasing some of the impact force. The raised base 1 contains a housing 6 for housing the device's internal electrical control components and batteries.

[0022] A metering device 3 is installed on the top of the raised base 1. The metering device 3 includes an outer cylinder 31, a metering tube 32, and a liquid collection funnel 33. The outer cylinder 31 is installed at the top of the first electric telescopic rod 2, which is installed at the center inside the raised base 1. It is used to push the metering device 3 out of the top of the protective area of ​​the protective cylinder 4, so that it can work when it rains.

[0023] The collection funnel 33 is located at three-fifths of the height inside the outer cylinder 31. The metering tube 32 is installed at the bottom center inside the outer cylinder 31, and the top of the metering tube 32 is connected to the bottom of the collection funnel 33, forming a rainwater guiding and water metering structure. A filter screen 34 is provided directly above the collection funnel 33 inside the outer cylinder 31. The outer surface of the filter screen 34 is conical to facilitate the filtration of impurities and prevent rainwater overflow.

[0024] The filter screen 34 extends outside the outer cylinder 31 via a second electric telescopic rod 35. The second electric telescopic rod 35 is located on the central axis inside the metering tube 32, and its diameter is smaller than the inner diameter of the liquid collection funnel 33's lower liquid hole, ensuring that rainwater flows smoothly into the annular metering space inside the metering tube 32. A drive motor 36 is installed at the top of the second electric telescopic rod 35, and the output shaft end of the drive motor 36 is fixedly connected to the center of the filter screen 34. Thus, when some impurities clog the filter screen 34, the second electric telescopic rod 35 can push it out of the outer cylinder 31, and then the drive motor 36 can be started to make the filter screen 34 rotate rapidly, thereby throwing out the impurities above and completing the self-cleaning operation.

[0025] A mounting base 7 is installed at the bottom of the raised base 1. The mounting base 7 is fixed to the ground by positioning bolts 8 on the outer ring to ensure the stability of the device. A circular solar panel 9 is installed on the outside of the outer cylinder 31 to provide continuous power to the device using solar energy, realizing the unattended automatic monitoring function. The diameter of the solar panel 9 is smaller than the inner diameter of the protective cylinder 4, which also ensures that the solar panel 9 can be recycled into the interior of the protective cylinder 4 along with the meter 3.

[0026] The bottom of the outer cylinder (31) is equipped with a drain valve pipe (37) that is connected to the bottom of the metering tube (32). The drain valve pipe (37) is equipped with a solenoid valve to drain the internal liquid for the next metering operation.
