Description

Technical Field

[0001] This utility model relates to the field of camera water meter technology, specifically a camera water meter suitable for harsh environments. Background Technology

[0002] With the increasing demand for refined water resource management and the development of intelligent and Internet of Things technologies, camera water meters, as a type of smart water meter that can provide additional functions such as reading recording and leakage detection, are gradually replacing traditional mechanical water meters. Camera water meters usually have a built-in camera to capture images of the meter's reading dial or encoder dial, and achieve remote automatic meter reading and status monitoring through image recognition technology or direct transmission of image data. However, most camera water meters do not have a sealed internal structure, which allows dust in the air to enter the interior through gaps, making the internal components of camera water meters prone to damage and reducing the service life of camera water meters.

[0011] This utility model provides a camera-based water meter suitable for harsh environments, which has the following beneficial effects:

[0012] (1) This utility model, by setting a circular groove, a protective disc and a sealing structure, drives the threaded rod to rotate through the turntable, and the connecting ring slides on the surface of the threaded rod. The connecting ring drives the moving rod to move in the concave plate, and then the sealing ring moves in the protective disc. After moving, the sealing ring will be engaged in the circular groove.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a camera water meter suitable for harsh environments includes a pipe body 1, a camera meter 2 connected to the outside of the pipe body 1, a protective plate 4 overlapping the top of the camera meter 2, a sealing structure 5 slidably connected inside the protective plate 4, a circular groove 7 opened inside the camera meter 2, and a snap-fit ​​structure 6 provided outside the camera meter 2, the snap-fit ​​structure 6 being connected to the protective plate 4. The sealing structure 5 includes a sealing ring 501, a concave plate 502, a threaded rod 505, and a connecting ring 504. A moving rod 503 is fixedly connected above the sealing ring 501, and a turntable 506 is fixedly connected to the top of the threaded rod 505.

[0021] like Figure 1 and Figure 3 As shown, a guide rod 3 is rotatably connected to the outside of the camera 2. The guide rod 3 is connected to the protective plate 4. A threaded rod 505 is rotatably connected above the protective plate 4. A concave plate 502 is fixedly connected to the protective plate 4. A sealing ring 501 is slidably connected inside the concave plate 502. A moving rod 503 is slidably connected inside the concave plate 502. The moving rod 503 is connected to a connecting ring 504. The connecting ring 504 is threadedly connected to the outside of the threaded rod 505. The sealing ring 501 is slidably connected inside the protective plate 4.

[0022] By setting the concave plate 502, since the concave plate 502 is fixedly connected above the protective disc 4, and the sealing ring 501 will slide within the protective disc 4 and the concave plate 502 when subjected to pushing or pulling force, the concave plate 502 plays a certain guiding role in the movement of the sealing ring 501, thus preventing the sealing ring 501 from shifting its position when moving.

[0023] like Figure 4 As shown, the snap-fit ​​structure 6 includes a first mounting plate 601 and a second mounting plate 602. The first mounting plate 601 is fixedly connected to the outside of the camera 2, and the second mounting plate 602 is fixedly connected to the outside of the protective plate 4. The second mounting plate 602 overlaps the top of the first mounting plate 601. A limiting plate 604 is snapped into the first mounting plate 601, and the limiting plate 604 is snapped into the second mounting plate 602. A snap-fit ​​block 603 is provided above the second mounting plate 602, and an elastic plate 605 is provided above the limiting plate 604. The snap-fit ​​block 603 and the elastic plate 605 are snapped together.

[0024] By setting a limiting plate 604, the protective plate 4 is attached to the top of the camera 2, while the second mounting plate 602 will overlap with the first mounting plate 601. The limiting plate 604 is interlocked with the first mounting plate 601 and the second mounting plate 602, so that the limiting plate 604 can reduce the gap between the first mounting plate 601 and the second mounting plate 602, so that the protective plate 4 and the camera 2 can fit tightly together.

[0025] This utility model provides a camera-based water meter suitable for harsh environments, and its specific working principle is as follows:

[0026] When the camera water meter is used to protect the area of ​​camera meter 2, the protective plate 4 can be attached to the top of camera meter 2, and the second mounting plate 602 will be attached to the first mounting plate 601. The limiting plate 604 will be inserted into the first mounting plate 601 and the second mounting plate 602, and the elastic plate 605 will be attached to the locking block 603.

[0027] The turntable 506 drives the threaded rod 505 to rotate, while the connecting ring 504 slides on the surface of the threaded rod 505. The connecting ring 504 then drives the moving rod 503 to move within the concave plate 502. After that, the sealing ring 501 moves within the protective disc 4 and is engaged in the circular groove 7.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
