It mainly includes an image acquisition and processing module, a power management module, and a mechanical mounting structure. The image acquisition and processing module and the power management module are both installed in a transparent housing.
[0004] Currently, mechanical installation structures generally use clamps to fix the transparent housing to traditional water meters. However, when maintaining the components inside the transparent housing, it is necessary to remove the clamps and the transparent housing completely, which is inconvenient and affects the maintenance effect. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that in the prior art, transparent housings are usually fixed to the meter casing with clamps, and when maintaining the components inside the transparent housing, it is necessary to remove the clamps and the transparent housing completely, which affects the maintenance efficiency. Therefore, a direct reading structure for water meter cameras is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A water meter camera direct-reading structure includes a transparent housing and a pair of clamps for fixing the transparent housing to a meter casing. An outer cylinder is rotatably disposed within the clamps, and an inner cylinder is threadedly connected to the outer cylinder. A pressure ring is fixedly disposed at the top of the inner cylinder. A bottom plate is fixedly disposed at one end of the transparent housing extending into the inner cylinder, with the top and bottom of the bottom plate abutting against the pressure ring and the top of the meter casing, respectively. A retaining ring is fixedly disposed within the clamps, with the top of the retaining ring abutting against the bottom of the meter casing. A rubber wiper strip is rotatably disposed within the transparent housing for cleaning water stains on the glass surface of the meter casing.

The vertical rods are slidably connected to the fixed plate, and a baffle is fixedly installed at one end of the vertical rods that passes through the fixed plate. An elastic element is provided between the fixed plate and the top plate.
[0009] Furthermore, the elastic element includes a spring, which is sleeved on the outer wall of the vertical rod, and the two ends of the spring abut against the fixed plate and the top plate, respectively.
[0010] To facilitate limiting the movement of the outer cylinder, preferably, the inner wall of the hoop plate is provided with a rotating groove, a rotating ring is fixedly provided at the bottom of the outer cylinder, the rotating ring is rotatably connected in the rotating groove, and the hoop plate is provided with a limiting member for limiting the rotation of the rotating ring.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.
[0022] Example: Reference Figures 1-4A water meter camera direct-reading structure includes a transparent housing 4 and a pair of clamping plates 1 for fixing the transparent housing 4 to the meter housing. Both clamping plates 1 are arc-shaped, and ear plates 103 are fixedly provided at both ends of each clamping plate 1. Through holes are provided on the ear plates 103. The pair of clamping plates 1 are fixed to the outer wall of the meter housing by first bolts. That is, the pair of clamping plates 1 are respectively clamped to the outer wall of the meter housing, and then the first bolts are passed through the through holes on the ear plates 103 respectively. A nut is threaded onto one end of each ear plate 103, thus fixing the pair of clamping plates 1 to the meter housing. An arc-shaped clamping pad 102 is fixedly provided on the inner wall of the clamping plate 1. The clamping pad 102 is made of rubber, nylon, or polyurethane, preferably rubber. The inner wall of the retaining pad 102 abuts against the outer wall of the watch case. During fixing, this reduces slippage between the retaining plate 1 and the outer wall of the watch case, improving the fixing effect. It also reduces indentation on the outer wall of the watch case, improving usability. An outer cylinder 2 is rotatably mounted inside the retaining plate 1, and an inner cylinder 3 is threadedly connected to the outer cylinder 2. Anti-slip textures are fixedly provided on the top outer walls of both the outer cylinder 2 and the inner cylinder 3 to facilitate rotation, reduce slippage, and simplify operation. A pressure ring 301 is fixedly mounted on the top of the inner cylinder 3. A base plate 401 is fixedly mounted at one end of the transparent shell 4 extending into the inner cylinder 3. The base plate 401 has a rotating annular structure. During fixing, the top and bottom of the base plate 401 are respectively connected to the pressure ring 301. 1. The inner tube 3 abuts against the top of the watch case. Furthermore, to improve the sealing effect, a sealing gasket 6 is provided between the bottom of the base plate 401 and the top of the watch case. The top and bottom of the sealing gasket 6 abut against the base plate 401 and the watch case respectively. A retaining ring is fixed inside the clamp plate 1, with its top abutting against the bottom of the watch case. When the inner tube 3 is tightened, the pressure ring 301 exerts force on the top of the watch case, and the retaining ring exerts force on the bottom of the watch case. This improves the fixing effect and reduces the phenomenon of the clamp plate 1 sliding upwards along the axial direction, which could lead to the problem of the transparent shell 4 not being securely fixed. In use, when fixing the clamp plate 1 to the watch case, first, the outer tube 2 is fitted onto the watch case, and the clamp plate 1 is used to fix the outer tube 2 to the watch case. Then, the sealing gasket 6 and the transparent shell 4 are sequentially fitted onto the watch case. The bottom and top of the sealing gasket 6 abut against the top of the watch case and the bottom of the base plate 401, respectively. The inner cylinder 3 is set on the outer wall of the transparent shell 4. Finally, the outer wall of the inner cylinder 3 is threaded to the inner wall of the outer cylinder 2, so that the bottom of the pressure ring 301 abuts against the top of the base plate 401. Continue to tighten the inner cylinder 3 to fix the transparent shell 4 on the watch case. When disassembling, loosen the inner cylinder 3 and remove it from the outer cylinder 2. The transparent shell 4 can then be removed from the watch case, which facilitates the maintenance of the components and modules inside the transparent shell 4 and improves the performance. A rubber squeegee 503 is rotatably installed inside the transparent shell 4. The length of the rubber squeegee 503 is greater than the radius of the watch case glass. It is used to clean water stains on the surface of the watch case glass and improve the acquisition effect of the image acquisition and processing module.
[0023] In use, the outer cylinder 2 is restricted to the outer wall of the watch case by using the hoop plate 1, and then the transparent shell 4 is threaded to the outer cylinder 2 through the inner cylinder 3. When assembling and disassembling the transparent shell 4, there is no need to remove the hoop plate 1, which can improve the assembly and disassembly efficiency and facilitate the maintenance of the components inside the transparent shell 4.
[0024] Reference Figure 3 and Figure 4 An mounting ring 5 is rotatably mounted on the inner wall of the transparent housing 4. A top plate 502 is fixedly mounted on the top of the rubber wiper strip 503 and is placed inside the mounting ring 5. A gear is rotatably mounted inside the transparent housing 4 and meshes with the inner wall of the mounting ring 5. A servo motor or motor, preferably a servo motor, is provided inside the transparent housing 4 to drive the gear to rotate. During use, the mounting ring 5 is driven to rotate by the gear, which in turn drives the rubber wiper strip 503 to rotate around the axis of the transparent housing 4 via the top plate 502, thereby wiping away water stains on the watch glass and improving clarity.
[0025] Reference Figure 3 and Figure 4 A fixing plate 501 is fixedly installed on the inner wall of the mounting ring 5, and at least two vertical rods are fixedly installed on the top plate 502. Here, we prefer two rods. The vertical rods are slidably connected to the fixing plate 501, and the top plate 502 can be raised and lowered along the vertical rods on the fixing plate 501. A baffle is fixedly installed at one end of the vertical rod that passes through the fixing plate 501, and an elastic element is provided between the fixing plate 501 and the top plate 502. In use, by elastically setting the top plate 502 on the fixing plate 501, on the one hand, the contact effect between the bottom of the rubber wiper strip 503 and the top of the glass of the watch case can be automatically adjusted, which is convenient for cleaning. On the other hand, it can reduce interference when fixing the transparent shell 4 and improve the use effect.
[0026] Reference Figure 3 and Figure 4 The elastic element can be elastic rubber. Here, we prefer a spring. The spring is sleeved on the outer wall of the vertical rod, and the two ends of the spring abut against the fixed plate 501 and the top plate 502 respectively. In use, by sleeved on the vertical rod, the cleaning effect of the rubber wiper 503 on the glass of the watch case can be adjusted under the action of the spring force.
[0027] Reference Figure 3 and Figure 4 A rotating groove 101 is provided on the inner wall of the hoop plate 1, and a rotating ring 201 is fixedly provided at the bottom of the outer cylinder 2. The rotating ring 201 is rotatably connected in the rotating groove 101, and a limiting member is provided on the hoop plate 1 to limit the rotation of the rotating ring 201. In use, by providing a rotating groove 101 on the inner wall of the hoop plate 1, the outer cylinder 2 can be limited and supported, thereby improving the use effect.
[0028] Reference Figure 1 and Figure 2 The limiting component can be a pin or a buckle. Here, we design the limiting component as follows: a second bolt is threaded onto the hoop plate 1. Multiple sets of circumferentially evenly distributed positioning holes are opened on the rotating ring 201. There are two to twenty sets of positioning holes, preferably twelve sets. A positioning rod matching the positioning hole is fixedly installed at one end of the second bolt that extends into the rotating groove 101. The positioning rod is slidably connected in the positioning hole. In use, by limiting the outer cylinder 2 to the hoop plate 1 with the second bolt, when the inner cylinder 3 is rotated to fix the transparent shell 4, the outer cylinder 2 can be prevented from rotating with the inner cylinder 3, which would prevent it from being fixed. The hoop plate 1 is fixed to the outer wall of the watch case with the first bolt. A limiting groove is fixedly opened on the inner wall of the hoop plate 1. A connecting plate is fixedly installed on the outer wall of the watch case. The connecting plate is located in the limiting groove, and the inner wall of one side of the limiting groove abuts against the side of the connecting plate. Under the obstruction of the connecting plate, when the inner cylinder 3 is rotated, the hoop plate 1 can be prevented from rotating, which would affect the fixing effect.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
