[Instrument latest patent] A modular intelligent water meter

Content Description

The utility model relates to the technical field of water meters, and more particularly to a modular intelligent water meter.

Background of the invention

With the increasing development of the urban water supply industry, high-quality water supply management becomes an urgent need for urban public utilities. The construction of intelligent water networks will also be an important way to promote water resources management. The smart meters of user terminals are an important component of smart water networks. Part and design key links. At present, the common mechanical metering tap water meter records the amount of water used by the mechanical controller. It does not have the data exchange function and the communication capability. It is difficult to read the meter manually, and the phenomenon of missed copy and estimated copying is often found.

The smart water meter is a new type of water meter that uses modern micro-electronics technology and modern sensing technology to measure water consumption and transmit water data and settlement transactions. The signal transmission between the functional units in the existing smart water meter is realized by cables, which makes it easy to affect the other units when the controller is disassembled and installed. Usually, the water meter is made into a whole.

In the existing smart water meter, the failure rate of the electronic components of the water meter is relatively high, and internal electronic components, batteries, etc. are easily damaged. When the internal electronic control device malfunctions or is damaged, the entire water meter needs to be removed. Remove and replace the failed mechanical or electrical parts. Because the internal components of the existing water meter are complex in structure and have many transmission wires, the difficulty in installation and disassembly is increased, and replacement and maintenance are difficult. Maintenance personnel often replace the entire water meter with high replacement cost.

Summary of the Invention

The utility model provides a modular intelligent water meter which overcomes the above problems or at least partly solves the above problems. The device can solve the defects of inconvenient installation and disassembly of the water meter and high maintenance cost.

According to the technical solution of the present invention, a modular intelligent water meter is provided. The water meter includes a valve-controlled watchcase assembly, a module assembly and an electric actuator assembly. The module assembly is detachably connected to the electric actuator assembly. The electric actuator assembly is detachably connected to the valve handle assembly.

As a further improvement of the above technical solution, the module assembly is mounted above the electric actuator assembly through a snap structure. The buckle structure is used to connect the module assembly and the electric actuator assembly, which has the advantages of reliable connection, convenient installation and disassembly. The module assembly is mounted above the electric actuator assembly by means of a mounting screw. The assembly module is used to connect the module assembly and the electric actuator assembly, which has the advantages of reliable connection, convenient installation and disassembly. Each side of the module assembly and the electric actuator assembly is correspondingly provided with a boss, and the boss is provided with a screw hole for mounting the assembly screw. With the bosses provided on the sides, the module assembly and the electric actuator assembly can be easily assembled using the assembly screws.

The upper ends of the module assembly and the electric actuator assembly are provided with vertical threaded holes. The assembly screws are installed from above into the threaded holes, and the installation and disassembly operations are convenient and quick.

A tamper-proof plug is provided above the assembly screw. By setting the tamper-proof plug, the smart meter can be effectively prevented from being disassembled and the meter can be effectively protected. The electric actuator assembly is mounted above the valve handle assembly via a plurality of coupling screws. The valve body assembly is provided with and for use with the electricity

a connecting member connected to the lower end of the actuator assembly, wherein the connecting member and the lower end of the electric actuator assembly are respectively provided with corresponding screw mounting holes, and a plurality of the coupling screws are installed from below into the threaded mounting holes; The valve control case assembly and the electric actuator assembly can be reliably fixedly connected together. The connecting member is provided with four and is disposed in parallel with the lower end surface of the electric actuator assembly.

The valve control case assembly includes a ball valve case, a cover, a joint, a ball core, a valve stem, a movement, a movement signal wheel, a magnetic steel, and the like, and forms part of the base table. The electric actuator assembly includes components such as a motor and a transmission gear set. The components of the electric actuator assembly as a whole are easy to install and disassemble. When the electric actuator assembly is damaged, it is removed from the valve handle assembly. Remove it, simple and quick operation.

The module assembly includes components such as an intelligent electronic module, a battery, and a sensor. The components of the module assembly as a whole are easy to install and disassemble. When the module assembly is damaged, it is removed from the electric actuator assembly. Yes, simple and quick operation.

Based on the above technical solutions, the modular intelligent water meter proposed by the utility model, the valve control case assembly, the module assembly and the electric actuator assembly of the water meter are respectively modularized, and each module adopts a detachable structure, which makes the various modules The connection, installation and disassembly are convenient, simplifying the installation and disassembly of maintenance workers. Compared with the replacement of the entire water meter when the existing water meter is damaged, the utility model only needs to replace a specific module, which can greatly save the maintenance cost of the smart water meter and has wide applicability.
