Split type water meter provided with seal chamber

Abstract

The invention discloses a split type water meter provided with a seal chamber. The water meter comprises a water meter mechanical body, a casing, an upper cover and a connecting piece, wherein an electronic component box and a battery box are arranged on the casing, the electronic component box comprises an electronic component case and a cover plate, the battery box comprises a battery case and a cap, the water meter mechanical body and the casing are connected through the connecting piece, the connecting piece is fixed above the water meter mechanical body through a screw, buckles are arranged on the inner side wall of the casing, and clamping grooves matched with the buckles are formed in the outer side wall of the connecting piece; the electronic component case and the cover plate are connected through ultrasonic welding to form the seal chamber. Compared with the prior art, the split type water meter has the advantages that the design of integral molding and clamping type connection is adopted, components are few, and the water meter is convenient to install and replace; the electronic component case and the cover plate are fixed through ultrasonic welding, so that water tightness and air tightness can be realized, and better waterproof and dustproof effects are realized.

Description

technical field [0001] The invention relates to a water meter, in particular to a split water meter with a sealed cavity. Background technique [0002] With the development of sensor technology and communication technology and the demand of water supply companies for accurate metering and intelligent management of water meters, smart water meters have also been widely developed. People's research on smart water meters focuses more on how to measure more accurately and manage more intelligently, and often ignores the convenience of installation and maintenance. By adopting the magnetic sensitive sensor technology, the electromechanical separation of the water meter can be realized, figure 1 It is an existing wireless remote water meter, but its structure has the following deficiencies: 1. The electronic component housing above the mechanical water meter has many structural components, and there are many installation steps. The whole needs to be fastened to the mechanical wat...
