Technical Field

[0001] This application relates to the field of fluid metering equipment, and in particular to an electromechanical separation photoelectric direct-reading water meter. Background Technology

[0002] Smart water meter technology is developing rapidly and plays a crucial role in the field of water supply metering. With technological advancements, smart water meters are constantly being upgraded and iterated, significantly improving the efficiency and accuracy of water resource management. The emergence of mechanical and electronic water meters has made water consumption recording more convenient and accurate, providing strong support for the refined management of urban water supply systems. In recent years, photoelectric direct-reading technology, with its unique advantages, has become a key research focus in the field of smart water meters and is expected to propel smart water meter technology to new heights. This series of technological developments enables water supply companies to better understand water usage and optimize water resource allocation, which is of great significance for water conservation and ensuring water supply security.

[0003] In the development of smart water meters, various technologies have been adopted to achieve water volume measurement and data reading. Mechanical water meters are a relatively traditional method, utilizing gear transmission to drive an impeller through water flow, which in turn drives a gear set to measure water volume. This method is relatively simple in structure and low in cost, and was widely used for a long time. However, its readings rely on manual meter reading, requiring staff to check meter readings at each household, resulting in high workload and low efficiency. Electronic water meters introduce sensor technology, converting mechanical signals into electrical signals, thus enabling remote meter reading. This eliminates the tediousness of manual meter reading and improves data collection efficiency, but due to the use of numerous electronic components, it faces many reliability challenges. In recent years, photoelectric direct-reading technology has emerged, combining optical and electronic technologies. It uses photoelectric sensors to achieve accurate water volume measurement and data transmission, offering advantages such as high precision and long lifespan. However, most current photoelectric direct-reading water meters adopt an electromechanical integrated design, with the mechanical meter body directly contacting the water flow, while the photoelectric sensor is susceptible to external environmental influences. Existing smart water meter technology has significant shortcomings. Mechanical water meters are inefficient and prone to errors when read manually, failing to meet the high-efficiency requirements of modern water supply management. Electronic water meters are susceptible to electromagnetic interference, and prolonged immersion in water can cause circuit aging, affecting normal operation and data accuracy. While existing photoelectric direct-reading water meters have certain advantages, their mechatronic design makes the mechanical meter body prone to accumulating impurities, leading to impeller jamming and gear wear, affecting metering accuracy. Similarly, dust, moisture, or dirt on the surface of the photoelectric sensor in the photoelectric meter body can cause abnormal light signal transmission or reception, resulting in reading errors. To ensure normal operation and metering accuracy, regular cleaning of both the mechanical and photoelectric meter bodies is necessary, but the existing water meter structure hinders disassembly of both. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide an electromechanical separation photoelectric direct-reading water meter.

[0005] A photoelectric direct-reading water meter with electromechanical separation includes a mechanical body. A mounting groove is formed on one side of the mechanical body, and a photoelectric body is disposed within the mounting groove. The photoelectric body and the mechanical body are detachably connected. A plug-in groove is formed on one side of the mechanical body, and a plug-in block is provided on the photoelectric body. A fixing bolt is provided on the side of the photoelectric body away from the mechanical body, and a threaded hole is formed on the mechanical body. By adopting the above technical solution, when installing the photoelectric body, the user inserts the plug-in block of the photoelectric body into the groove, and then tightens the bolt on the photoelectric body into the threaded hole of the mechanical body, thus connecting and fixing the photoelectric body and the mechanical body. Simultaneously, the plug-in fit combined with bolt fixing facilitates the disassembly and installation of the photoelectric body and the mechanical body. Preferably, a receiving groove is formed on the plug-in block, and a compression spring is disposed within the receiving groove. A pin is provided at the end of the compression spring, and a pin hole is formed on the inner wall of the plug-in groove. By adopting the above technical solution, when the user installs the photoelectric meter body, the tension of the compression spring pushes the pin into the pin hole, which not only increases the contact area between the photoelectric meter body and the mechanical meter body, making the connection between the photoelectric meter body and the mechanical meter body more stable, but also facilitates disassembly by allowing the photoelectric meter body and the mechanical meter body to spring apart easily. Preferably, a photoelectric sensing unit is slidably connected inside the photoelectric meter body, and a notch is opened on the side of the mechanical meter body near the photoelectric sensing unit. The photoelectric sensing unit extends into the notch and abuts against the counting gear, so that the photoelectric detection unit can read the water meter. The mechanical body is provided with a pushing component that drives the photoelectric sensing unit to slide to abut against the counting gear. By adopting the above technical solution, when the user installs the photoelectric meter body on the mechanical meter body, the pushing component automatically pushes the photoelectric sensing unit to abut against the counting gear, facilitating the normal operation and reading of the water meter. Preferably, the pushing component includes a push rod disposed on the mechanical body, a positioning frame fixedly connected inside the photoelectric sensor, the positioning frame being vertically arranged and used for inserting the push rod, and a pushing rod being slidably connected to the positioning frame. The pushing rod is used to abut against the end of the photoelectric sensing unit and push the photoelectric sensing unit to slide into the mechanical body. By adopting the above technical solution, when the user uses the device, the photoelectric sensor is installed in the mounting slot, the push rod is automatically inserted into the positioning frame, and the pushing rod is pushed upward, thereby automatically pushing the photoelectric sensing unit to abut against the counting gear.

[0006] Preferably, the top of the push rod has a guide slope, and the end of the photoelectric sensing unit has an abutment slope that cooperates with the guide slope. By adopting the above technical solution, when the user uses the device, the push rod pushes the push rod upwards, and through the cooperation of the abutment slope and the guide slope, pushes the photoelectric sensing unit horizontally to abut against the counting gear. Preferably, the mechanical body has a receiving cavity below the notch, and a baffle is vertically slidably connected within the receiving cavity. A return spring is provided at the bottom of the baffle. By adopting the above technical solution, when the user disassembles the photoelectric watch body, the tension of the return spring pushes the baffle upwards, and the baffle blocks the notch, preventing dust and impurities from entering the components of the mechanical watch body. Preferably, a rubber sealing gasket is provided at the top of the notch and the receiving cavity of the mechanical watch body. By adopting the above technical solution, when the user uses the device, the rubber sealing gasket seals the connection between the mechanical watch body and the photoelectric watch body, preventing dust and water from entering the mechanical watch body and the photoelectric watch body.

[0013] The following will be combined with the appendix Figure 1-5The technical solutions in the embodiments of this utility model are described in further detail below. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0014] This application mainly adopts a photoelectric direct-reading water meter solution that separates electromechanical components and facilitates disassembly and assembly, achieving the effect of convenient cleaning and maintenance of the water meter and ensuring metering accuracy. The following is a further detailed description of this application.

[0015] The electromechanical separation photoelectric direct-reading water meter provided in this application embodiment includes a mechanical meter body 1 and a photoelectric meter body 2. The mechanical meter body 1 has an installation groove 11 on one side, and the photoelectric meter body 2 is installed in the installation groove 11. The photoelectric meter body 2 and the mechanical meter body 1 are detachably connected. This design facilitates regular cleaning of both and avoids the water meter's normal operation and metering accuracy from problems such as the accumulation of impurities.

[0016] Specifically, a slot 12 is provided on one side of the mechanical watch body 1, and a connector block 21 is provided on the photoelectric watch body 2. The connector block 21 is usually a block structure, and the material can be plastic or metal, such as the common aluminum alloy, which has a certain strength and durability. It is installed on the photoelectric watch body 2, which can be manufactured in one piece or fixed by welding, bolt connection, etc. The shape of the slot 12 is adapted to the connector block 21. For example, if the connector block 21 is rectangular, then the slot 12 is a rectangular groove. When installing the photoelectric watch body 2, the connector block 21 is inserted into the slot 12 to achieve initial positioning and connection. A fixing bolt 26 is provided on the side of the photoelectric watch body 2 away from the mechanical watch body 1, and a threaded hole 16 is provided on the mechanical watch body 1. The bolt is generally made of metal, such as stainless steel bolt, which has good corrosion resistance. The bolt passes through the photoelectric watch body 2 and mates with the threaded hole 16 on the mechanical watch body 1. Tightening the bolt will firmly connect the photoelectric watch body 2 and the mechanical watch body 1 together. During disassembly, simply loosen the bolts to remove the photoelectric watch body 2 from the mechanical watch body 1. This plug-in connection combined with bolt fixing ensures the stability of the connection while facilitating disassembly and installation.

[0017] Additionally, the plug block 21 has a receiving groove 211, within which a compression spring 22 is installed. A pin 23 is attached to the end of the compression spring 22. The receiving groove 211 is a space within the plug block 21 used to house the compression spring 22 and the pin 23. The compression spring 22 is typically a helical metal spring, made of materials such as carbon steel, and possesses good elasticity. The pin 23 is generally a cylindrical metal rod, with a hemispherical head for easy insertion into the pin 23 hole. When installing the photoelectric watch body 2, when the plug block 21 is inserted into the plug groove 12, the tension of the compression spring 22 pushes the pin 23 outwards. A pin 23 hole is provided on the inner wall of the plug groove 12, and the pin 23 is inserted into this hole. This not only increases the contact area between the photoelectric watch body 2 and the mechanical watch body 1, making their connection more stable, but also makes it easier for the photoelectric watch body 2 and the mechanical watch body 1 to spring apart during disassembly, further facilitating the disassembly operation.

[0018] A photoelectric sensing unit 24 is slidably connected inside the photoelectric meter body 2, and the photoelectric sensing unit 24 can slide along a certain track inside the photoelectric meter body 2. It is usually composed of components such as a photoelectric sensor and is used to detect the water meter's counting status. A notch 13 is opened on the side of the mechanical meter body 1 near the photoelectric sensing unit 24, and the photoelectric sensing unit 24 extends into the notch 13 to abut against the counting gear so that the photoelectric detection unit can read the water meter reading. A push assembly 25 is provided on the mechanical meter body 1 to drive the photoelectric sensing unit 24 to slide to abut against the counting gear.

[0019] The pushing component 25 includes a push rod 251 mounted on the mechanical watch body 1. The push rod 251 is generally a columnar structure and can be made of metal or plastic. It is fixed to the mechanical watch body 1, and the push rod 251 performs its corresponding function when the photoelectric watch body 2 is installed into the mounting slot 11 of the mechanical watch body 1. A positioning frame 252 is fixedly connected inside the photoelectric watch body 2. The positioning frame 252 is vertically arranged and used for inserting the push rod 251. The positioning frame 252 can be a square frame structure and can be made of plastic or metal. It is fixed inside the photoelectric watch body 2 by welding, bolt connection, or other methods. A push rod 253 is slidably connected inside the positioning frame 252. The push rod 253 is generally a rod-shaped structure and can be made of metal. The push rod 253 is used to abut against the end of the photoelectric sensing unit 24 and push the photoelectric sensing unit 24 to slide into the mechanical meter body 1. The top of the push rod 253 is provided with a guide slope 2531, and the end of the photoelectric sensing unit 24 is provided with an abutment slope 241 that cooperates with the guide slope 2531. When the photoelectric meter body 2 is installed in the mounting groove 11, the push rod 251 is automatically inserted into the positioning frame 252, and at the same time, the push rod 253 is pushed to slide upward. Through the cooperation of the guide slope 2531 and the abutment slope 241, the vertical movement of the push rod 253 can be converted into the horizontal sliding of the photoelectric sensing unit 24, so that the photoelectric sensing unit 24 can slide smoothly to abut against the counting gear, and then automatically push the photoelectric sensing unit 24 to abut against the counting gear, ensuring that the water meter can work normally and read the value.

[0020] The mechanical watch body 1 has a receiving cavity 14 located below the notch 13. A baffle 141 is vertically slidably connected within the receiving cavity 14. The baffle 141 is generally a plate-shaped structure and can be made of plastic or metal. A return spring 142 is provided at the bottom of the baffle 141. The return spring 142 is usually a helical metal spring. When the photoelectric watch body 2 is removed, the tension of the return spring 142 will push the baffle 141 to slide upward. The baffle 141 blocks the notch 13, preventing dust and impurities from entering the components of the mechanical watch body 1 and protecting the internal structure of the mechanical watch body 1 from the influence of external impurities.

[0021] A rubber sealing gasket 15 is provided on top of the notch 13 and the receiving cavity 14 of the mechanical meter body 1. The rubber sealing gasket 15 is generally made of rubber material, which has good elasticity and sealing performance. It can be fixed to the mechanical meter body 1 by means of adhesive or other methods. The rubber sealing gasket 15 seals the connection between the mechanical meter body 1 and the photoelectric meter body 2, preventing dust and water from entering the mechanical meter body 1 and the photoelectric meter body 2, further ensuring the normal operation and service life of the water meter.

[0022] The implementation principle of this embodiment is as follows: This electromechanical separation photoelectric direct-reading water meter, through a reasonable structural design, separates the mechanical meter body 1 and the photoelectric meter body 2, and adopts a detachable connection method, which facilitates regular cleaning and maintenance of both. The cooperation between the plug block 21 and the plug slot 12, the bolt and the threaded hole 16 ensures the stability of the connection. The design of the pin 23, the pin 23 hole, and the compression spring 22 further enhances the stability of the connection and facilitates disassembly. The cooperation between the pushing component 25, the guide slope 2531, and the abutment slope 241 enables the photoelectric sensing unit 24 to accurately abut against the counting gear, ensuring normal water meter reading. The baffle 141 and the rubber sealing gasket 15 effectively protect the internal structure of the mechanical meter body 1 and the photoelectric meter body 2, reducing the impact of external factors on the water meter. Compared to existing technologies, this method solves the problems of impurity accumulation and sensor contamination caused by the mechatronics design of existing water meters, improving the metering accuracy and service life of the water meter, and reducing maintenance costs.
