Today, I will introduce a national invention authorized patent-a gear positioning wireless intelligent remote transmission anti-theft water meter based on NB-IOT. The patent was applied by Xiamen Jingzhun Intelligent Water Meter Co., Ltd., and was granted an authorization announcement on June 1, 2018.

Description of content

The invention relates to the field of water meters, in particular to a gear positioning wireless intelligent remote transmission anti-theft water meter based on NB-IOT.

Background of the invention

The existing wireless remote transmission anti-theft water meter needs to install a water meter controller on the base meter. However, in some existing technologies, the water meter controller and the base meter often use a fixed lock or design a corresponding fixing base on the water meter for fixed connection. Among them, a fixing hole is provided on the fixing base, and a screw is used for fixing. The existing fixing methods are that the water meter controller will still loose after it is installed on the base meter, making the fixing of the water meter controller and the base meter unstable. Once the fixing is not stable, the internal components of the water meter controller will be damaged. The phenomenon occurs.

Summary of the invention

In order to solve the deficiencies mentioned in the above background technology, the present invention provides a gear positioning wireless intelligent remote transmission anti-theft water meter based on NB-IOT.

The figure is a schematic structural view of the present invention.

The invention includes a base meter and a water meter controller; the bottom side of the water meter controller is provided with a screw rod, one end of the screw rod is provided with a rotating fixing head, and the rotating fixing head is connected to the screw rod through an internal screw hole; The water meter controller is set on the front side of the water meter controller; the water meter controller is set on the base meter, the rotating fixed head is embedded in the gap between the water meter controller and the base meter; the position of the base meter corresponding to the rotating fixed head A protrusion is provided on the top.

On the basis of the above structure, the shape of the rotating fixed head is consistent with the contour of the gap between the water meter controller and the base meter. The base watch also includes a watch cover with a hollow structure in the middle; the bottom side of the watch cover is provided with a fixed washer, and the inner ring of the fixed washer is provided with fixed internal teeth; the bottom side of the water meter controller is provided with a fixed disk; the fixed disk is provided There are fixed external teeth, fixed internal teeth and fixed external teeth are fitted together.

A positioning notch is provided on the fixed gasket, and a positioning block matching the positioning notch is provided on the inner side of the watch cover. It also includes a glass cover and a sealing ring; the sealing ring is provided on the dial of the base watch, the glass cover is provided on the sealing ring, and the fixed gasket is provided on the glass cover. The watch cover wraps and fixes the glass cover, the fixed gasket and the sealing ring. A wireless transmission device is provided in the water meter controller; the wireless transmission device performs data transmission through the NB-IOT. An alarm device is provided in the water meter controller.

The NB-IOT-based gear positioning wireless intelligent remote transmission anti-theft water meter provided by the present invention cooperates with the rotation fixed head provided on the bottom side of the water meter controller and the protrusion provided on the base meter body, without the need to set too many on the base meter The fixed structure does not need to punch holes on the base meter, so that the water meter controller can be firmly fixed on the base meter, preventing the water meter controller from being easily damaged due to insecure installation, and convenient installation, which greatly saves costs.
