Description

Technical Field

[0001] This utility model relates to the field of smart water meter technology, and in particular to a fully sealed dry-type electromechanical separation smart water meter. Background Technology

[0002] Under the current trend of refined water resource management and smart city construction, smart water meters, as key metering devices, undertake the important tasks of accurately measuring water consumption, assisting in water conservation management, and remote data collection. As the coverage of water supply networks continues to expand, the application scenarios of smart water meters are becoming increasingly complex, covering urban residential communities, industrial parks, and outdoor water supply facilities in frigid regions. However, existing smart water meter technologies are insufficient to fully meet the stringent requirements of diverse scenarios, and technological improvements and innovations are urgently needed. From a practical application perspective, on the one hand, as the construction of smart cities increases the requirements for the real-time and accuracy of data, the shortcomings of traditional smart water meters in terms of metering stability and data reliability are gradually becoming apparent; on the other hand, extreme weather events are frequent, and winters in cold regions are long and the temperature is extremely low. Conventional water meters are not frost-resistant enough, leading to frequent failures in the water supply system, which seriously affects the normal water use of residents and industrial production. At the same time, dust, corrosive gases, and rainwater erosion in the complex outdoor environment also pose higher challenges to the sealing and protection performance of water meters.

[0003] The existing technology has the following shortcomings: 1) Single metering system with poor reliability: Most smart water meters use a single electronic metering system, which is highly dependent on power supply and the stability of electronic components. Once a power outage occurs, electronic components age and are damaged, or communication modules fail, the metering function is immediately interrupted, and data continuity cannot be guaranteed. This results in missing water usage data for users, causing great trouble for the billing management of water supply departments and the water cost accounting for users. 2) Insufficient low-temperature adaptability and high maintenance costs: In cold regions, ordinary water meters are not equipped with effective antifreeze measures. Water pipes and internal components are very prone to freezing and expansion, which can cause pipe rupture, deformation of the water meter's mechanical structure, or damage to electronic components. This not only causes frequent water outages but also significantly increases maintenance and replacement costs and manpower, seriously affecting the quality and stability of water supply services. 3) Weak sealing and protection, short service life: Some water meters have unreasonable sealing structure design, which makes it difficult to resist the intrusion of outdoor dust, rainwater and corrosive substances. During long-term use, dust accumulation can easily cause mechanical transmission parts to jam, and rainwater infiltration may cause short circuits in electronic circuits, thereby shortening the service life of the water meter and increasing the overall replacement cost and maintenance frequency of the equipment. Summary of the Invention

[0004] This utility model's fully sealed dry electromechanical separation smart water meter effectively solves the problems of unstable metering, low-temperature damage, and insufficient protection of traditional water meters by using a dual electromechanical system for coordinated metering, a heating component for freeze protection, and a fully sealed protective structure.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see attached Figure 1 -Appendix Figure 5 As shown, Figure 1 As shown, the fully sealed dry electromechanical separation smart water meter of this embodiment includes a water meter shell 1. A heating mechanism 2 is fixedly installed at the bottom of the water meter shell 1. The heating mechanism 2 includes a mounting shell 201. A heating plate 202 is fixedly installed at the bottom inner part of the mounting shell 201. A first heat-conducting plate 203 is fixedly installed at the top of the mounting shell 201. A second heat-conducting plate 204 is fixedly embedded at the bottom of the mounting shell 201. A longitudinal heat-conducting rod 205 is fixedly connected to the bottom of the second heat-conducting plate 204. A transverse heat-conducting rod 206 is fixedly connected to the outer wall of the longitudinal heat-conducting rod 205. The advantage is that in cold regions or outdoor use scenarios in winter, the heating mechanism can effectively prevent the water in the water passage 207 from freezing. Once the water freezes, it will not only prevent the water flow from passing normally and affect the water meter measurement, but may also damage the internal structure and pipes of the water meter due to the expansion force of the ice. The heating mechanism maintains the liquid state of the water flow, ensures the continuous normal operation of the water meter, reduces maintenance costs and water outage time caused by freezing damage, and extends the service life of the water meter.

[0022] Please see attached Figure 1 -Appendix Figure 5As shown, the bottom of the water meter casing 1 has an electronic mounting slot 14 and a mechanical structure mounting slot 15, connected by a connecting hole 141. The electronic mounting slot 14 houses a processor 140. Its functions include: an electronic display screen that shows accurate digital metering results in real time, allowing users to quickly read the data; and a mechanical display mechanism that uses a pointer or dial to achieve traditional metering display, still functioning normally even in the event of a power outage or malfunction of the electronic system. Its advantages include suitability for various usage scenarios. In household water use, the electronic display screen allows users to intuitively understand real-time water consumption, facilitating water conservation management. The mechanical display mechanism serves as a backup metering method; in the event of a power outage or damage to electronic components, users can still obtain water consumption data, ensuring metering continuity and avoiding disputes arising from metering interruptions.

[0023] Please see attached Figure 1 -Appendix Figure 5 As shown, the outer wall of the first heat-conducting plate 203 and the inner wall of the mechanical structure mounting groove 15 are fixedly connected, and the space formed therebetween is used for the installation and placement of the mechanical structure. Function: The measuring device detects the flow rate of water flowing through the water channel and simultaneously outputs corresponding signals to the electronic system and the mechanical system to drive the electronic display and mechanical counting. Role: In industrial water monitoring scenarios, high-precision measuring equipment can accurately measure large amounts of water in real time, providing data support for enterprise cost accounting and resource management; its dual-output design ensures that the electronic and mechanical systems work synchronously, and the dual measurement results can be mutually verified, improving data reliability and avoiding measurement deviations caused by single system errors.

[0024] Please see attached Figure 1 -Appendix Figure 5 As shown, an electronic display screen 12 and a mechanical display mechanism 13 are fixedly installed on the top of the water meter housing 1, and the top of the processor 140 is fixedly connected to the bottom of the water meter housing 1.

[0025] Please see attached Figure 1 -Appendix Figure 5 As shown, the electronic display screen 12 and the processor 140 are interconnected by circuitry. The mechanical structure mounting slot 15 and the mechanical display mechanism 13 cooperate with each other. Function: The measuring device 4 transmits the mechanical power generated by the water flow to the mechanical transmission components in the mechanical structure mounting slot 15. Through gear sets and other structures, it drives the pointer or turntable of the mechanical display mechanism 13 to rotate, realizing the mechanical metering and display of water consumption. Advantages: The mechanical display mechanism is a reliable backup metering method. When the electronic system cannot work due to faults, power outages, or other reasons, the mechanical display mechanism can still operate normally, ensuring the continuity of water consumption metering. In some areas with low dependence on electronic equipment or unstable power supply, the mechanical display mechanism ensures the reliability of water consumption data obtained by users and management departments, avoiding metering interruptions due to electronic system failures.

[0026] Please see attached Figure 1 -Appendix Figure 5 As shown, a measuring device 4 is fixedly installed at the bottom of the water meter casing 1, and the output end of the measuring device 4 is matched with the electronic mounting slot 14 and the mechanical structure mounting slot 15 respectively.

[0027] Please see attached Figure 1 -Appendix Figure 5 As shown, the mounting shell 201 is connected to a fixed mounting tube 21, and the second heat-conducting plate 204 is disposed inside the fixed mounting tube 21. The top of the second heat-conducting plate 204 and the bottom of the heating plate 202 are in contact with each other.

[0028] Please see attached Figure 1 -Appendix Figure 5 As shown, the bottom of the fixed installation tube 21 is fixedly connected to the housing 3, and the longitudinal heat-conducting rod 205 is inserted into the longitudinal part of the housing 3.

[0029] Please see attached Figure 1 -Appendix Figure 5 As shown, the bottom of the longitudinal heat-conducting rod 205 is fixedly installed on the inner bottom of the housing 3, and a water channel 207 is provided inside the housing 3. The transverse heat-conducting rod 206 is inserted into the water channel 207.

[0030] Please see attached Figure 1 -Appendix Figure 5 As shown, one end of the water channel 207 is connected to the inlet connecting pipe 5, and the other end of the water channel 207 is connected to the measuring device 4 via a fixed flange. One end of the measuring device 4 is connected to the outlet connecting pipe 6 via a flange. The top of the water meter housing 1 is hinged and threaded with a cover 11. The cover 11 and the mechanical display mechanism 13 cooperate with each other. The cover is installed on the top of the water meter housing via a hinge thread, covering and protecting the mechanical display mechanism and other top components, preventing dust, rainwater, etc. from entering. The advantage is that in outdoor public water facilities and other usage scenarios, the cover can resist the corrosion of harsh environments and ensure the normal operation of the mechanical display mechanism. This design reduces mechanical component failures caused by external pollution, lowers maintenance frequency, and prevents malicious damage, ensuring the accuracy and safety of water meter readings. Function: The cover is installed on the top of the water meter casing via a hinged thread, covering and protecting the mechanical display mechanism and other top components, preventing dust, rainwater, etc., from entering. Benefits: In outdoor public water facilities and other usage scenarios, the cover can resist harsh environmental corrosion, ensuring the normal operation of the mechanical display mechanism, reducing mechanical component failures caused by external pollution, lowering maintenance frequency, and preventing malicious damage, thus ensuring the accuracy and safety of water meter readings.

[0031] Usage and Working Principle: During installation, connect the inlet pipe 5 tightly to the water source pipe using a flange, and connect the outlet pipe 6 to the water supply pipe, ensuring a leak-free seal at the connection. Simultaneously, install the cover 11 on the top of the water meter casing 1 using a hinge thread, covering and protecting the electronic display screen 12 and the mechanical display mechanism 13. This completes the external installation and fixing of the water meter. During startup, when water flows into the water channel 207 through the inlet pipe 5, the water meter automatically starts. The measuring device 4 begins real-time detection of the water flow rate, and the electronic display screen 12 is simultaneously powered on, displaying current water consumption, flow rate, and other data. At this point, the water meter enters normal working condition. For daily use and maintenance, users can monitor the water flow through the electronic display screen 12. The display screen 12 provides real-time access to accurate water consumption data. In cold environments, the heating mechanism automatically starts or stops based on the set temperature, requiring no additional user intervention. Regularly check the seal of the cover 11 to prevent external debris from entering the water meter. If any abnormalities are detected, perform maintenance promptly. The water flow measurement principle involves the measuring device 4 using turbine and ultrasonic technologies to convert the physical flow rate into two signals. On one hand, mechanical power is generated and transmitted through transmission components to gear sets and other mechanical transmission components within the mechanical structure mounting slot 15. On the other hand, an electrical signal is generated and transmitted to the processor 140 within the electronic mounting slot 14, achieving dual detection of water flow rate. After receiving the electrical signal from the measuring device 4, the processor 140 processes and calculates the data to obtain relevant information such as water consumption, and transmits this information to the electronic display screen 12. The electronic display screen 12 presents this information to the user in digital form. The mechanical power transmitted by the measuring device 4, through gear transmission and other mechanical structures in the mechanical structure mounting slot 15, drives the pointer or turntable of the mechanical display mechanism 13 to rotate, realizing the mechanical metering and display of water consumption. The two work together: the electronic display is used for accurate reading and intelligent management, while the mechanical display serves as a backup to ensure the continuity of data reading. Regarding the heating mechanism, when the ambient temperature is lower than a set threshold, the heating plate 202 automatically powers on and generates heat. The heat is transferred to the longitudinal heat-conducting rod 205 and the transverse heat-conducting rod 206 through the second heat-conducting plate 204. At the same time, the first heat-conducting plate 203 prevents heat loss upwards, so that the heat is concentrated to heat the water flow in the water channel 207. The longitudinal heat-conducting rod 205 and the transverse heat-conducting rod 206 form a three-dimensional heat-conducting network, which uniformly increases the water flow temperature, prevents the water from freezing in low-temperature environments, protects the internal structure and pipes of the water meter, and ensures that the water meter operates normally in cold environments. The overall collaborative working principle of the fully sealed dry electromechanical separation smart water meter is that all components work together. The measuring device 4, as the core detection component, transmits the water flow signal to the electronic system and the mechanical system at the same time. The electronic system realizes intelligent data processing and display through the processor 140 and the electronic display screen 12.The mechanical system relies on the mechanical structure mounting slot 15 and the mechanical display mechanism 13 to complete traditional metering; the heating mechanism ensures smooth water flow in low-temperature environments; and the cover 11 provides protection for key internal components. These components work together to achieve accurate metering, stable operation, and adaptability to various complex environments.
