Description

Technical Field

[0001] The present invention relates to the technical field of water meters, and in particular to an ultrasonic water meter. Background Art

[0002] In the field of water meter technology, ultrasonic water meters are widely used due to their high precision and low wear rate. Traditional ultrasonic water meters are mainly composed of a housing and a module box, which contains key electronic components such as the main control circuit board and communication module. These components work together to achieve accurate measurement and data transmission of water flow.

[0003] However, there are some shortcomings in the ultrasonic water meter in the prior art, especially in the maintenance and replacement of the communication module. As the core component for the water meter to exchange data with the external system, the communication module requires complex maintenance operations once a failure occurs. Specifically, maintenance personnel must first disassemble the housing and then remove the module box before they can access and replace the communication module. This process is not only time-consuming and labor-intensive, but may also cause damage to other components of the water meter, increasing maintenance costs and potential failure risks.

[0004] In addition, frequent disassembly and assembly may also lead to a decrease in the sealing performance of the water meter, affecting the long-term stability and reliability of the water meter. Therefore, the communication module replacement and maintenance process of the existing ultrasonic water meter needs to be optimized to improve the maintenance efficiency of the water meter and reduce the maintenance cost.

[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figures 1 to 3 An ultrasonic water meter includes a shell, a module box 3, a main control circuit board 4 and a communication module. The module box 3 is installed in the shell, and the main control circuit board 4 is installed in the module box 3. The shell is provided with an installation groove 21 connected to the interior thereof. The communication module is installed in the installation groove 21 and is electrically connected to the main control circuit board 4.

[0024] As can be seen from the above description, the beneficial effect of the present invention is that by designing a mounting slot 21 outside the shell that is connected to the internal space and installing the communication module in the mounting slot 21, the communication module can be quickly accessed and replaced. This design significantly reduces the difficulty of maintenance and repair, because it is no longer necessary to completely disassemble the shell and the module box 3 to access the communication module. In addition, the electrical connection between the communication module and the main control circuit board 4 ensures the stability and reliability of data transmission. At the same time, this modular design allows the communication module to be upgraded or repaired separately without interfering with other components of the water meter, thereby improving the maintenance efficiency and service life of the water meter. In addition, this design also helps to reduce the failure rate of the water meter caused by maintenance operations and enhances the overall reliability of the water meter.

[0025] Furthermore, a packaging cover plate is included, which covers the mounting groove 21 and is detachably connected to the housing.

[0026] As can be seen from the above description, the addition of the packaging cover provides physical protection for the communication module, preventing the external environment (such as dust, moisture, etc.) from damaging the communication module. At the same time, the detachable connection design between the packaging cover and the shell allows the packaging cover to be quickly removed when the communication module needs to be replaced or maintained, thereby improving the convenience of maintenance.

[0027] Furthermore, the packaging cover plate is provided with a packaging cover 6, and the packaging cover 6 covers the communication module.

[0028] As can be seen from the above description, the provision of the encapsulation cover 6 further protects the communication module from direct contact or external damage. The design of the encapsulation cover 6 also helps to centrally protect the communication module and reduce the complexity of maintenance.

[0029] Furthermore, a sealing member is provided on the outer side wall of the packaging cover 6 , and the sealing member is arranged around the packaging cover 6 and contacts the side wall of the installation groove 21 .

[0030] As can be seen from the above description, the setting of the seal between the packaging cover 6 and the mounting groove 21 provides a sealing effect, prevents the intrusion of moisture and dust, protects the communication module from environmental factors, and improves the reliability and durability of the water meter.

[0031] Furthermore, the material of the sealing component is nitrile rubber, hydrogenated nitrile rubber, EPDM rubber, silicone rubber, chloroprene rubber, fluororubber, tetrafluoroethylene rubber, fluorosilicone rubber, perfluororubber, polytetrafluoroethylene rubber or acrylate rubber.

[0032] From the above description, it can be seen that the seals are made of a variety of rubber materials, which have good chemical corrosion resistance and temperature resistance. The most suitable sealing material can be selected according to different working environments to ensure that the water meter can work stably in various environments.

[0033] Furthermore, the shell is provided with a prompt mark, and when the packaging cover plate is connected to the shell, the packaging cover plate is shielded by the prompt mark.

[0034] As can be seen from the above description, the design of the prompt mark helps the user to identify whether the package cover is installed correctly. When the package cover covers the prompt mark, it means that it is installed in place. This design improves the intuitiveness and accuracy of user operation.

[0035] Furthermore, the reminder sign is made of reflective material.

[0036] From the above description, it can be seen that the warning sign uses reflective material to improve the visibility of the sign, especially in a dimly lit environment, the reflective material can reflect light, making the warning sign more eye-catching and improving safety.

[0037] Furthermore, the mounting groove 21 is provided at the bottom of the housing.

[0042] From the above description, it can be seen that the detachable design of the shell makes the installation and maintenance of the module box 3 more convenient. The installation cavity between the upper shell 1 and the lower shell 2 provides a stable installation environment for the module box 3. At the same time, the connection design between the lower shell 2 and the module box 3 also ensures the stability and sealing of the module box 3.
