Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to a sealed IoT non-magnetic water meter. Background Technology

[0002] With the development of smart cities and IoT technologies, water meters, as crucial terminal devices for water resource measurement and management, are also upgrading towards intelligence and information technology. IoT-enabled non-magnetic water meters, through built-in electronic sensors and remote communication modules, can achieve real-time monitoring of water meter operation status, remote reading of water usage data, and anomaly alarms, thus improving the level of intelligent water management. Compared to traditional mechanical water meters, non-magnetic water meters are not affected by magnetic fields, resulting in more accurate measurement and more reliable operation. They are particularly suitable for residential buildings, commercial buildings, and other scenarios with high requirements for measurement accuracy and data security.

[0003] Existing IoT-enabled non-magnetic water meters typically include a flow measurement unit, a signal acquisition module, a data processing chip, and a communication module, all housed within the basic casing of a traditional water meter. The top cover often employs a flip-top design, housing the battery compartment and control circuit board. The overall structure relies on mechanical clips or screws for fixation and is not specifically designed to withstand outdoor rain, dust, or human-caused damage. This structure is primarily used indoors or in enclosed spaces, offering limited resistance to environmental interference. If moisture or foreign objects enter the electronic compartment, it can easily cause communication failures or component damage.

[0004] Existing IoT non-magnetic water meters generally adopt a flip-top structure, but the top cover lacks a reliable locking and sealing design, making it susceptible to rainwater infiltration and dust intrusion during long-term outdoor use. This not only affects the stable operation of the internal electronic modules, but may also be subject to human-caused damage due to the exposed structure, resulting in data loss, metering abnormalities or communication failures, seriously affecting the overall operating efficiency and security of the smart water system. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sealed IoT non-magnetic water meter, which aims to improve the problems of existing water meter top cover flip structure lacking effective locking and sealing design, and being susceptible to rain, dust intrusion and human damage during outdoor use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sealed IoT non-magnetic water meter, comprising a meter body, an upper shell fixedly connected to the upper surface of the meter body, a flip cover attached to the upper surface of the upper shell, and a sealing component provided on the inner wall of the flip cover;

A suction cup is fixedly connected to one end of the lead screw, and the suction cup is attached to the upper surface of the flip cover.

[0008] Furthermore, a check pipe is fixedly connected to the outer wall of the surface, a fixed pipe is fixedly connected to the outer wall of the check pipe, a fixed block three is fixedly connected to the inner wall of the fixed pipe, a rotating shaft is rotatably connected to the inner wall of the fixed block three, a connecting rod is fixedly connected to the outer wall of the rotating shaft, a sealing disc is fixedly connected to the outer wall of the connecting rod, and a valve disc is fixedly connected to the outer wall of the sealing disc.

[0009] Furthermore, a water outlet pipe is fixedly connected to the outer wall of the outer casing, and a communication module is fixedly connected to the outer wall of the upper casing.

[0010] Furthermore, the outer wall of the communication module is slidably connected to the outer wall of the flip cover, and a fixing block is fixedly connected to the outer wall of the upper housing.

A connecting rod 21 is fixedly connected to the outer wall of the rotating shaft 23.

[0029] Working principle: When a sealed IoT non-magnetic water meter is required, and it is suitable for harsh environments, an upper housing 7 is fixedly connected to the upper surface of the meter body 1. A flip cover 6 is set on top of the upper housing 7. A sealing ring 15 is fitted to the inner wall of the flip cover 6. Under the elastic force of the spring 16, the sealing ring 15 always maintains a sealed fit with the upper housing 7. A fixing block 2 13 is fixedly connected to the outer wall of the flip cover 6.

The wall is connected to the suction cup 12 via the lead screw 11. Rotating the lead screw 11 can drive the suction cup 12 to fit against the upper surface of the flip cover 6, further pressing the flip cover 6, so that the sealing ring 15 forms a stable pressing state against the upper housing 7, enhancing the sealing effect. This structure can effectively solve the problems of traditional water meter flip covers 6 having no locking and weak sealing, providing effective protection in harsh environments such as outdoor rain and dust, reducing the risk of human-caused opening and damage, and protecting the operational safety and service life of the numerical display panel 17, the digit wheel 18 and the communication module 5 inside the upper housing 7.

[0030] In addition, to prevent backflow of water at the user end from affecting the operation of the water meter, a check pipe 3 is installed on the outer wall of the meter body 1. The check pipe 3 is connected to a fixed pipe 4. A fixed block 22 is installed inside the fixed pipe 4. The inner wall of the fixed block 22 is rotatably connected to a rotating shaft 23. The rotating shaft 23 drives the connecting rod 21 to rotate. A sealing disc 19 is fixedly connected to the outer wall of the connecting rod 21. A valve disc 20 is then connected to the outer wall of the sealing disc 19. When the water flows in the forward direction, the water flow pushes the valve disc 20 to open, and the water can flow normally through the outlet pipe 2. When backflow or back pressure occurs in the user's pipe network, the valve disc 20 closes under the action of water pressure. The sealing disc 19 and the inner wall of the check pipe 3 form a barrier to prevent backflow of water. This check structure achieves unidirectional control of water flow through mechanical means, without relying on electronics or sensors, and achieves long-term stable operation. It can effectively avoid problems such as water meter mismeasurement, data abnormality and cross-contamination of pipe network caused by backflow, and improve the overall safety, data accuracy and sanitary reliability of IoT water meter operation and public water supply system.
