Problems solved by technology
[0003] In order to solve the above-mentioned technical problems, the present invention provides a smart water meter of the Internet of Things, to solve the problem that the current Internet of Things water meter is usually installed by screwing the screw thread. Since the Internet of Things water meter is easily damaged and malfunctioned by external influences, it needs to be installed. It is time-consuming and laborious to disassemble during maintenance. Moreover, the connection between the pipes at both ends and the IoT water meter cannot be quickly fixed and installed. At the same time, the IoT water meter is not effectively protected, and it is prone to freezing in cold weather.

Embodiment 1
[0034] The protective shell includes the following raw materials in parts by weight:
[0035] 28 parts of denatured polyphenylene ether, 14 parts of ASA resin, 7 parts of SMA resin, 15 parts of highly dispersed nano calcium carbonate, 2 parts of antimony trioxide, 2 parts of polybutadiene rubber, 0.2 part of calcium stearate;
[0036] The preparation process of the highly dispersed nano-calcium carbonate is as follows: the calcium carbonate with a particle size of 100nm to 200nm is dissolved in an ethanol solution, then a composite dispersant is added, and the highly-dispersed nano-calcium carbonate is obtained through ultrasonic stirring and drying; The composite dispersant is composed of dispersant B and dispersant A in a mass ratio of 1:1;
[0037] The dispersant A has the following structural formula:
[0038]
[0039] The dispersant B has the following structural formula:
[0040]
[0041] The preparation method of the protective shell is as follows:

The invention relates to the technical field of water meters, and particularly provides an intelligent Internet of Things water meter which comprises an outer protection mechanism. A heat preservation sealing plate is hinged to the top of the outer protection mechanism; a fixing mechanism is fixedly arranged on the inner side of the bottom of the outer protection mechanism; and the fixing mechanism comprises a base, a sliding block, a rotating sleeve and a fixed connecting block, the fixed connecting block is fixedly arranged in the middle of the inner side of the bottom of the base, and the rotating sleeve is rotationally connected to the outer side of the fixed connecting block. Through the arrangement of a pressing handle and a sliding block, the installation and maintenance efficiency of the Internet of Things water meter is improved, the Internet of Things water meter is conveniently and rapidly installed and disassembled in the mode that the pressing handle is rotated to drive a movable supporting frame and a movable plate to connect a connecting pipe with a connecting opening, and in the mode that the sliding block is movably clamped with a connecting frame, and the practicability is high. And compared with a labor-consuming matching mode needing thread meshing, disassembly is easy.
Description
technical field [0001] The invention belongs to the technical field of water meters, and more specifically relates to an intelligent Internet of Things water meter. Background technique [0002] Through the analysis of the existing intelligent IoT water meters, it is found that although the above water meters can be scaled, they are generally installed by screwing the thread. Since the IoT water meters are easily damaged and malfunctioned by external influences, it takes time to disassemble them for maintenance. It is laborious, and the installation is so difficult that the pipes at both ends and the connection port of the IoT water meter cannot be quickly fixed and installed. At the same time, the IoT water meter is not effectively protected, and it is prone to freezing in cold weather. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a smart water meter of the Internet of Things, to solve the prob...
