Description

Technical Field

[0001] The utility model belongs to the technical field of fluid measuring devices, and in particular relates to a water meter with a detachable alarm structure. Background Art

[0002] Water meters are instruments used to measure water flow. They are generally divided into two categories: volumetric water meters and velocity water meters. They originated in the UK and have a history of nearly 200 years. When choosing water meter specifications, you should first estimate the size and range of the flow rate used under normal circumstances, and then choose the water meter with the specification that is closest to the value as the first choice. In the past, most water meters were old-fashioned mechanical water meters, which were read manually. When the user was not at home or did not cooperate, the meter could not be read, affecting water use management.

[0003] With the development of the times, smart water meters have gradually replaced some traditional mechanical water meters and have been widely used. Currently, most of the smart water meters used are integrated structures including mechanical parts and electronic parts. The mechanical parts and electronic parts are located in the same shell. When the shell leaks, or the battery power inside the electronic part is insufficient, or when the circuit board inside the electronic part fails abnormally, the entire water meter needs to be disassembled with tools for maintenance, which causes inconvenience to the inspection and replacement work. Therefore, it is necessary to design a water meter with a detachable alarm structure. Utility Model Content

[0004] In order to solve the above technical problems, the utility model further proposes a water meter with a detachable alarm structure.

[0005] The specific technical scheme of the utility model is as follows: a water meter with a detachable alarm structure, comprising a water meter case and an electronic module, a flow monitoring module being arranged in the water meter case, a locking assembly for locking the electronic module being installed on the water meter case, a central control module being arranged in the water meter case for being electrically connected to the flow monitoring module and the electronic module, the electronic module comprising a shell, a button being arranged in the shell, a sound and light alarm module being arranged in the shell, and metal contacts being arranged on the water meter case for being electrically connected to the sound and light alarm module.

[0006] Furthermore, the locking assembly includes a locking shell, which is installed on the water meter shell, and a plurality of balls are arranged in a circular array on the locking shell. A locking sleeve for limiting the movement of the balls is slidably connected to the locking shell, and the locking sleeve is connected to the locking shell by a spring. A release cavity for storing the balls is provided on the locking sleeve, and an annular groove for cooperating with the balls for locking is provided on the shell.

[0007] Furthermore, a limiting block is arranged on the locking shell, a limiting groove for cooperating with the limiting block is opened on the shell body, and the limiting block is slidably connected in the limiting groove.

[0008] Furthermore, a sealing ring is provided between the housing and the locking shell.

[0009] Furthermore, a retaining groove for installing a sealing ring is provided on the shell.

[0010] Furthermore, the locking sleeve is provided with an inclined surface for facilitating the ball to enter the release cavity.

[0011] Furthermore, the locking sleeve is symmetrically provided with grooves for facilitating the movement of the locking sleeve.

The flow detection module has various forms, which can be composed of a mechanical meter plus an electromechanical conversion module, or an ultrasonic pipe section plus a flow rate acquisition module. The flow detection module has extremely high sampling accuracy and can detect at least 1L of water volume changes, making the detected water volume more accurate. The central control module contains a single-chip microcomputer, a sensor acquisition interface, a timer, a memory and other devices, which can continuously collect water usage characteristics, and generate a water leakage alarm when it detects that the water usage exceeds the set threshold continuously. The audible and visual alarm module contains a communication circuit, an audible and visual prompt circuit, etc. When receiving an alarm signal sent by the communication interface, the module can send an audible and visual prompt. The sound and light alarm module is a replaceable structure. There is a battery inside the sound and light alarm module to power it. There is no need to use the battery inside the water meter, which reduces the loss of the water meter battery, extends the service life of the water meter battery, and has a low voltage prompt function. When the battery voltage is too low, the user can manually replace the module by himself, and there is no need to disassemble the entire water meter from the water pipe to replace the battery of the sound and light alarm module. The operation is more convenient. The user can replace it by himself, which reduces the difficulty of replacing the battery of the sound and light alarm module, thereby saving replacement time and making the operation more convenient. There is no need to disassemble the entire water meter from the water pipe, which ensures the sealing between the water meter and the water pipe. The water meter will not be damaged due to disassembly, which reduces the loss of the water meter, thereby extending the service life of the water meter. At the same time, by facilitating the replacement of the battery of the sound and light alarm module, the service life of the sound and light alarm module is extended, and the operation is more convenient. The water meter and the sound and light alarm module are connected by metal contacts for communication. Structurally, concave and convex mechanisms are respectively arranged on the water meter and the sound and light alarm module for positioning. After installation, the two are fastened by a locking assembly.
