[0002] In underground water supply systems, household water meters are the core components for measuring users' water consumption. The accuracy and efficiency of meter reading directly affect the level of precision in water supply management. The underground environment has significant unique characteristics. It is not only confined and dimly lit, but also constantly exposed to high humidity and dust. Some areas are accompanied by low-frequency vibrations. These environmental factors place stringent requirements on the structural stability, sealing and protection performance, and reliability of the meter reading device.

[0003] A search revealed Chinese Patent Publication No. CN219834318U, which discloses a meter reading device including a clamp, a housing structure, and an image acquisition component. The clamp is held in place on the side of the water meter, and the housing structure covers the meter dial and is fixedly connected to the clamp. A sealed cavity is formed inside the housing structure, and a transparent area is formed on the bottom wall of the sealed cavity to expose the meter dial. The image acquisition component is located in the sealed cavity and is used for communication connection with a remote terminal.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the height of the meter reading mechanism in existing automatic meter reading devices is mostly a fixed structure, which cannot be flexibly adjusted according to the height of the meter face of different water meter models; due to the diverse models of water meters for underground water supply users, the fixed-height meter reading mechanism is prone to misalignment between the camera and the meter face, resulting in the inability to clearly collect reading information and causing poor adaptability.

An anti-fog film is fitted on the inner wall of the protective cover.

[0028] See Figure 3 As shown, miniature fill lights are installed on both sides of the camera 9. The fill lights are electrically connected to the controller 8. A battery compartment 14 is provided on the upper end of the housing 7. A cover plate 15 is provided on the upper part of the battery compartment 14. The cover plate 15 is snapped into the housing 7. The cover plate 15 of the battery compartment 14 is sealed with a silicone sealing ring. Opening requires a special tool to prevent unauthorized operation. A protrusion 23 is provided on the upper end of the threaded cylinder 6. There are two protrusions 23. The two protrusions 23 are symmetrically installed on the threaded cylinder 6. The protrusions 23 facilitate the operator to drive the threaded cylinder 6 to rotate. A groove 16 is provided on the upper end of the housing 7.

[0029] See Figure 2 , Figure 3 , Figure 5 As shown, the groove 16 is provided on both sides of the battery compartment 14. A sealing assembly is provided between the lower end of the threaded cylinder 6 and the water meter 2. The sealing assembly includes a sealing ring 10. A locking block 12 is installed on the upper end of the sealing ring 10. A slot 13 is provided on the threaded cylinder 6 at the corresponding position of the locking block 12.

A rubber pad 11 is installed at the lower end of the sealing ring 10. The sealing ring 10 is made of artificial graphite material impregnated with phenolic resin, and the rubber pad 11 is made of hydrogenated nitrile rubber.

[0030] The implementation principle of the meter reading device for underground water supply in this application embodiment is as follows: First, select a sealing ring 10 that is compatible with the size of the water meter 2, align the upper end of the sealing ring 10 with the slot 13, and fix the sealing ring 10 to the lower end of the threaded cylinder 6 by snap-fit; screw the threaded cylinder 6 with the sealing ring 10 installed into the threaded hole 5 in the middle of the fixing frame 3, then place the middle of the fixing frame 3 directly above the water meter 2 to be monitored, and fix the fixing frame 3 to the water pipe 1 with the clamp 4; rotate the threaded cylinder 6 again so that the rubber pad 11 at the lower end of the sealing ring 10 fits against the surface of the water meter 2 to form a seal;

[0031] Then, pull the drive rod 20, which drives the toothed plate 19 away from the teeth 18. At the same time, the toothed plate 19 compresses the spring 21 until the toothed plate 19 separates from the teeth 18. Then, the operator drives the outer casing 7 to rotate through the groove 16. The outer casing 7 drives the camera 9 to rotate. The angle of the camera 9 is determined according to the arrow at the top of the outer casing 7 until the shooting angle of the camera 9 is aligned with the reading angle of the water meter 2. Release the drive rod 20, and under the action of the spring 21, push the toothed plate 19 to slide in the slide groove 22 and reset until the toothed plate 19 and the teeth 18 are fully engaged, locking the angle of the outer casing 7.

[0032] When reading the meter, the controller 8 triggers a working command and simultaneously turns on the camera 9 and the miniature supplementary lights on both sides; the camera 9 clearly captures the reading image of the water meter 2 dial, and after the image data is processed by the controller 8, it is directly stored and transmitted to the remote terminal to complete a single meter reading;

[0033] By unscrewing the threaded cylinder 6 in the reverse direction, the old sealing ring 10 can be removed along the slot 13; replace the new sealing ring 10 with a new one, and screw the threaded cylinder 6 back into the threaded hole 5 to restore the sealing effect; open the cover 15 of the battery compartment 14 to replace the depleted battery.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
