Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to a camera-type water meter. Background Technology

[0002] A camera-based water meter is a smart device that uses image recognition technology to automatically read water data, aiming to improve water resource management efficiency and reduce manual intervention. Its core function is to use a high-resolution camera to capture the reading area of ​​a traditional mechanical or digital water meter, and then accurately extract water consumption data using advanced optical character recognition (OCR) algorithms and pointer position detection technology. The system typically includes a camera module, a lighting system, a processor and storage unit, and a communication module, supporting wireless transmission methods such as Wi-Fi, LoRa, or NB-IoT, facilitating data upload to the cloud for analysis and management.

[0003] Camera-type water meters have the advantage of non-intrusive installation. They do not require modification of the existing water meter structure. Only an external camera device needs to be installed, which reduces the cost and technical difficulty of modification. The main structure consists of a transparent cover and mounting accessories. The transparent cover contains a camera module, lighting system, processor and storage unit, communication module and power supply, etc. The mounting accessories are used to fix the transparent cover to a traditional mechanical water meter or a digital water meter.

[0004] Existing installation accessories typically use two clamps to fix the transparent cover to the water meter. Because the clamps lack a positioning structure, the camera module's camera position needs to be adjusted by manually rotating the clamps. This often results in skewed numbers in the captured images, causing the system to fail to recognize or misrecognize them, thus affecting the accuracy of the readings. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the camera shooting position is difficult to adjust accurately in the prior art, and to propose a camera-type water meter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A camera-type water meter includes a water meter body, with multiple ear plates evenly distributed in a circle fixedly disposed on the outer wall of the water meter body casing. It also includes: a pair of arc-shaped retaining plates, the inner walls of which abut against the outer wall of the water meter body casing; the two ends of the pair of retaining plates are fixedly connected by connectors, and each end of the retaining plate is fixedly disposed with a fixing plate; the two sides of the ear plates abut against the fixing plates respectively; and a transparent cover with a rotating cylindrical structure, which engages between the two retaining plates when they form a ring structure.

[0008] To facilitate the installation of the transparent cover on the card plate, preferably, the top of the card plate is fixedly provided with an arc-shaped plate with an arc-shaped structure, the inner wall of the arc-shaped plate is provided with an arc-shaped groove, and the bottom of the transparent cover is fixedly provided with a fixing ring, which is engaged in the ring formed by the arc-shaped groove.

[0009] In order to limit the position of the transparent cover, the side wall of the fixing ring is further provided with a first plane, and the inner wall of the arc-shaped groove is provided with a second plane, and the first plane and the second plane are in contact with each other.

[0010] In order to adjust the installation height of the transparent cover on the card plate, multiple arc-shaped grooves are further provided, and the multiple arc-shaped grooves are equidistantly distributed along the axial direction of the arc-shaped plate.

[0011] Preferably, the connector includes a bolt, and each of the fixing plates has a through hole, with a nut threaded onto one end of the bolt that passes through the through hole.

[0012] Preferably, a fixing pad is fixedly provided on the fixing plate, and the two sides of the ear plate abut against the fixing pad respectively.

[0013] Furthermore, the fixing pad is made of rubber.

[0014] Preferably, a rubber pad is fixedly provided on the inner wall of each pair of the card plates, and the inner wall of the rubber pad abuts against the outer wall of the water meter body casing.

[0015] Preferably, both the card plate and the arc plate are made of stainless steel, and the card plate and the arc plate are integrally formed.

[0016] Preferably, the transparent cover is made of acrylic.

[0017] Compared with the prior art, this utility model provides a camera-type water meter with the following features:

[0018] Beneficial effects:

[0019] 1. This camera-type water meter uses a transparent cover that is snapped between a pair of plates. A fixing plate is then fixedly installed on the plates. When the pair of plates are arranged into a circle by the connector, the fixing plate abuts against the two sides of the ear plate on the outer wall of the meter casing. This limits the rotation direction of the plates on the circumference of the outer wall of the meter casing, ensuring that the camera module is as directly facing the digital area of ​​the water meter body as possible, facilitating system recognition and improving the accuracy of readings.

[0020] 2. This camera-type water meter has multiple arc-shaped grooves distributed vertically along the axis of the arc-shaped plate. The installation position of the transparent cover can be adjusted according to the actual height of the meter casing, thus improving its applicability.

[0021] All parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model involves fitting a transparent cover between a pair of plates, and then fixing a fixing plate on the plates. When the pair of plates are arranged into a circle by the connector, the fixing plate abuts against the two sides of the ear plate on the outer wall of the meter casing, thereby limiting the rotation direction of the plates on the circumference of the outer wall of the meter casing. This ensures that the camera module is as directly facing the digital area of ​​the water meter body as possible, facilitating system recognition and improving the accuracy of readings.

[0027] 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.

[0028] 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. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example:

[0030] Reference Figures 1-4A camera-type water meter includes a water meter body 1, which is preferably a traditional mechanical water meter. Multiple ear plates 101, evenly distributed in a circular pattern, are fixedly installed on the outer wall of the water meter body 1 casing. There are two to ten ear plates 101, preferably four. The meter also includes a pair of arc-shaped retaining plates 3, with the inner wall of the retaining plates 3 abutting against the outer wall of the water meter body 1 casing. The two ends of the pair of retaining plates 3 are fixedly connected by connectors, and fixing plates 301 are fixedly installed at both ends of each retaining plate 3. The sides of two non-adjacent ear plates 101 abut against the fixing plates 301. The fixing plates 301 are fixed to the bottom of both ends of the retaining plates 3 and extend downwards. When the pair of retaining plates 3 form a circle, the installation position of the retaining plates 3 can be restricted. At this time, the camera module is precisely aligned with the digital area of ​​the water meter body 1 dial, reducing skewness and improving the accuracy of system recognition. Preferably, the camera module is aligned with the water flow direction. The two ear plates 101 on the top are parallel to the water flow direction. The transparent cover 2, which has a cylindrical structure of rotation, houses the camera module, lighting system, processor and storage unit, communication module, and power supply, all of which are fixed inside the transparent cover 2 with screws. The transparent cover 2 is made of acrylic or tempered glass, and acrylic is preferred here. When a pair of locking plates 3 form a ring structure, the transparent cover 2 is locked between the pair of locking plates 3 to fix the transparent cover 2. In use, the transparent cover 2 is locked between the pair of locking plates 3, and a fixing plate 301 is fixedly set on the locking plate 3. When the pair of locking plates 3 are formed into a circle by the connector, the fixing plate 301 abuts against the two sides of the ear plates 101 on the outer wall of the meter casing, thereby limiting the rotation direction of the locking plates 3 on the circumference of the outer wall of the meter casing. This ensures that the camera module is as directly facing the digital area of ​​the water meter body 1 as possible, which facilitates system recognition and improves the accuracy of reading.

[0031] Reference Figures 1-3 An arc-shaped plate 4 with an arc structure is fixedly installed on the top of the card plate 3. The card plate 3 and the arc plate 4 are integrally formed. The arc plate 4 can be fixed to the card plate 3 by welding. Here, we prefer to form it as a whole by casting and then perform precision machining. In order to reduce the occurrence of rust, both the card plate 3 and the arc plate 4 are made of stainless steel. An arc groove 401 is opened on the inner wall of the arc plate 4. A fixing ring 201 is fixedly installed at the bottom of the transparent cover 2. The retaining ring 201 engages within the circular ring formed by the arc groove 401. In other words, when a pair of retaining plates 3 are fixed on the watch case, the two sets of arc plates 4 can form a circular structure, and the retaining ring 201 at the bottom of the transparent cover 2 can engage within the arc groove 401, making it convenient to fix the transparent cover 2. In use, first cover the transparent cover 2 onto the watch case, and then fix the pair of retaining plates 3 to the outer wall of the watch case. When fixing, the retaining ring 201 should be engaged within the arc groove 401 which is in the same plane to improve the performance.

[0032] Reference Figure 3 and Figure 4 A first plane 202 is fixedly provided on the side wall of the fixing ring 201. Here, we symmetrically arrange two first planes 202. A second plane 402 is fixedly provided on the inner wall of the arc groove 401. When locked, the first plane 202 and the second plane 402 fit together, which can prevent the transparent cover 2 from rotating after being fixed, thus affecting normal use.

[0033] Reference Figure 3 We have multiple arc-shaped grooves 401, ranging from two to ten. Here, we prefer five. The multiple arc-shaped grooves 401 are equidistantly distributed along the axial direction of the arc plate 4. In use, by having multiple arc-shaped grooves 401 and distributing them up and down along the axial direction of the arc plate 4, the installation position of the transparent cover 2 can be adjusted according to the actual height of the watch case, thereby improving the applicability.

[0034] Reference Figure 1 and Figure 2 The connector can be a cable tie, but here we prefer to use a bolt. Through holes are provided on the fixing plate 301. A nut is threaded onto one end of the bolt that passes through a pair of through holes, so as to fix the pair of clamping plates 3 to the outer wall of the watch case and improve the fixing effect.

[0035] Reference Figures 1-3 A fixing pad 302 is fixedly installed on the fixing plate 301. The two sides of the ear plate 101 are respectively abutted against the fixing pad 302. The fixing pad 302 is made of rubber or nylon. Here, we prefer rubber. In use, by fixing an elastic fixing pad 302 on the fixing plate 301, not only can the fixing effect between the card plate 3 and the watch case be improved, but the clamping effect on the transparent cover 2 can also be adjusted.

[0036] Reference Figure 3 Rubber pads are fixedly installed on the inner walls of both plates 3, and the inner walls of the rubber pads abut against the outer wall of the water meter body 1. In use, by fixing the rubber pads on the inner walls of the plates 3, not only can the fixing effect between the plates 3 and the meter body be improved, but damage to the surface of the meter body can also be reduced, thus improving the performance.

[0037] 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.
