Description

Technical Field

[0001] The present invention belongs to the technical field of non-magnetic imaging devices, and specifically relates to a non-magnetic imaging device for intelligent water meters. Background Art

[0002] The non-magnetic imaging device for intelligent water meters is an innovative technology in the field of water management. It realizes precise monitoring of the operating status of water meters through non-contact monitoring methods. This device combines a high-definition camera with intelligent image recognition technology. Without directly contacting the water meter or relying on magnetic components, it can capture the digital changes on the water meter dial in real time, ensuring the authenticity and reliability of measurement data. In practical applications, the device takes a long-distance photo of the water meter through an optical lens and uses a high-resolution sensor to obtain a clear dial image. The built-in AI algorithm automatically identifies the numbers and pointer positions in the image and converts them into specific water consumption data. The whole process does not require physical contact, avoiding measurement error problems caused by magnetic interference, mechanical wear, or water quality fouling in traditional water meters. At the same time, the device supports real-time data transmission function, and can upload the collected water usage information to the cloud platform through a wireless network, facilitating remote monitoring and management by the water supply department. One of the major advantages of this technology lies in its installation convenience. There is no need to modify or disassemble the existing water meter. Just aim the camera at the dial and fix it to complete the deployment, greatly reducing the construction cost and time. In addition, the device has strong environmental adaptability and can operate stably under complex conditions such as humidity, strong light, or low temperature, ensuring the continuity and accuracy of data collection. Through the remote monitoring function, water supply enterprises can grasp the water usage situation of users in real time, promptly discover abnormal water usage behaviors, and effectively prevent water resource waste and pipeline leakage problems. This non-intrusive monitoring method not only protects user privacy but also improves the intelligent level of water management, providing strong support for the construction of smart cities.

[0003] However, there are some problems that need to be solved urgently in the use process of the non-magnetic imaging device for intelligent water meters. First of all, it is extremely inconvenient to disassemble and repair this device. Its internal structure is complex, and all components are tightly connected, lacking a reasonable disassembly design, resulting in maintenance personnel being difficult to quickly and accurately find the fault point and carry out replacement or repair, consuming a lot of time and energy.

[0004] Secondly, the lens of the camera is very easy to get foggy. In actual use scenarios, whether in a humid environment or when the temperature around the water meter changes greatly, it is easy for fog to condense on the lens, which seriously affects the imaging clarity of the camera, and may thus cause inaccurate recognition of the water meter reading, affecting the accuracy and reliability of intelligent water meter measurement. Summary of the Invention

[0005] The purpose of the present invention is to provide a non-magnetic imaging device for intelligent water meters to solve the above problems and those mentioned in the background art.

[0006] To solve the above problems, the present invention provides a technical solution for a non-magnetic camera device of an intelligent water meter:

[0007] A non-magnetic camera device of an intelligent water meter includes a base. A connecting seat is in contact with the lower end of the base. A camera is provided at the lower end of the connecting seat. A slider is slidably connected inside the base. A connecting block is fixedly connected to the lower end of the slider.

[0008] Preferably, the clamping block is in contact with the base and is slidably connected to the clamping groove. Through the design of the clamping block, the connecting seat can be limited.

[0009] Preferably, a retaining ring is fixedly connected to the outer side of the threaded rod. The retaining ring is in contact with the inner wall of the base. Through the design of the retaining ring, the threaded rod can be limited.

[0010] Preferably, the limiting mechanism includes a pulling plate. A pulling plate is in contact with the outer side of the base. A limiting rod is fixedly connected to the side of the pulling plate close to the base. A limiting groove is formed inside the knob. A guiding block is fixedly connected to the outer side of the limiting rod. A guiding rod is fixedly connected inside the base. The guiding block is slidably connected to the base and is slidably connected to the guiding rod. A first spring is provided on the outer side of the guiding rod. Through the design of the limiting mechanism, the camera can be kept stably installed while being easily disassembled.

[0011] Preferably, the limiting rod is slidably connected to the base and is slidably connected to the limiting groove. Through the design of the limiting rod, the knob can be limited.

[0012] Preferably, one end of the first spring is in contact with the guiding block, and the other end of the first spring is in contact with the base. Through the design of the first spring, the limiting rod can be driven to limit the knob.

[0013] Preferably, the cleaning mechanism includes a fixed frame. A fixed frame is fixedly connected to the outside of the camera. A connecting rod is slidably connected inside the fixed frame. A motor is fixedly installed at the lower end of the fixed frame. A rotating rod is connected to the inside of the fixed frame through a bearing. The rotating rod is threadedly connected to the connecting rod. The output end of the motor is rotatably connected to the fixed frame and fixedly connected to the rotating rod. A fixed rod is fixedly connected to the inside of the fixed frame. The fixed rod is slidably connected to the connecting rod. One end of the connecting rod away from the fixed frame is fixedly connected to a mounting seat. A sliding rod is slidably connected inside the mounting seat. A second spring is arranged inside the mounting seat. One end of the second spring contacts the sliding rod, and the other end contacts the mounting seat. One end of the sliding rod close to the fixed frame is fixedly connected to a scraper. The scraper contacts the fixed frame. Through the design of the cleaning mechanism, the water vapor on the camera can be scraped off.

[0014] Preferably, a limiting ring is fixedly connected to the inside of the mounting seat. The limiting ring is slidably connected to the sliding rod. Through the design of the limiting ring, the sliding rod can be limited.

[0015] The beneficial effects of the present invention are as follows: The present invention relates to a non-magnetic camera device for an intelligent water meter, which has the characteristics of convenient disassembly and maintenance and efficient anti-fog cleaning. In specific use, compared with the traditional non-magnetic camera device for an intelligent water meter, the non-magnetic camera device of the present intelligent water meter has the following beneficial effects:

[0016] First of all, the device realizes rapid disassembly and assembly through the cooperation of the threaded rod and the slider. Rotating the knob drives the threaded rod to rotate, driving the slider to slide along the base, so that the clamping block disengages from the clamping groove of the connecting seat, and the camera can be separated from the base without complex tools or cumbersome steps. The retaining ring limits the displacement of the threaded rod to ensure stable operation. After disassembly, the locking state of the knob is released by the pull plate of the limiting mechanism, further simplifying the process. Compared with the traditional fixed structure, this design greatly shortens the maintenance time, reduces the labor cost, and at the same time avoids component damage caused by forced disassembly, improves the maintainability of the equipment, and ensures long-term stable operation.

[0017] Secondly, the camera is equipped with a dual anti-fog cleaning mechanism. The motor drives the rotating rod to rotate, and through threaded transmission, the connecting rod moves up and down, making the scraper fit the mirror surface for reciprocating scraping to remove the surface water vapor. The second spring pushes the sliding rod to ensure that the scraper is in close contact with the mirror surface, improving the cleaning effect. The fixed frame and the limiting ring restrict the movement track of the sliding rod to prevent deviation. When the mirror surface generates fog due to temperature difference or humidity, this mechanism can automatically or manually start the cleaning program to quickly restore a clear view, avoiding reading errors or image blurring caused by fog occlusion. The material of the scraper is wear-resistant and corrosion-resistant, extending the service life, ensuring the safety and reliability of the cleaning process, and significantly improving the adaptability of the equipment in complex environments.
