Intelligent gas meter sampling device

Abstract

The present invention discloses an intelligent gas meter sampling device. The intelligent gas meter sampling device comprises a machine shell, a shell cover is fixedly connected to one side of the machine shell, a protection plate is fixedly connected to the outer side of the machine shell, a mounting groove is formed in the top end of the shell cover, a fixing plate is fixedly connected to the inner wall of the mounting groove, and first fixing blocks are fixedly connected to the two sides of the inner wall of the machine shell. By arranging the pull rod, during mounting, the shell cover is placed at the top end of the machine shell, so that the second fixing block is inserted into the inner wall of the fixing groove, the sealing strip is tightly attached to the inner wall of the sealing groove by forcibly pressing, and at the moment, the first rack makes contact with the second rack under the action of the first spring to fix the second fixing block, so that the machine shelland the shell cover are effectively fixed and sealed. When a worker needs to overhaul, the pull rod is pulled, the pull rod drives the first rack to be separated from the second rack, then the machine shell and the shell cover can be separated, operation is convenient, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of intelligent gas meters, in particular to an intelligent gas meter sampling device. Background technique [0002] Smart gas meters have gradually replaced ordinary gas meters due to their advantages in charging and management. The accurate and effective electronic measurement of smart gas meters requires not only accurate measurement of the mechanical part of the gas meter, but also complete accuracy in the collection of electronic pulses. [0003] However, in actual use, the traditional smart gas meter sampling device is mostly a bolt-fixed structure, which takes time and effort when maintenance is required, and cannot be quickly disassembled and repaired. At the same time, most of the electronic counting parts of smart gas meters on the market now use Magnetic sampling, and temperature, environment, and individual differences will affect the magnetic strength, and there may be certain deviations in the s...

[0003] However, in actual use, the traditional smart gas meter sampling device is mostly a bolt-fixed structure, which takes time and effort when maintenance is required, and cannot be quickly disassembled and repaired. At the same time, most of the electronic counting parts of smart gas meters on the market now use Magnetic sampling, and temperature, environment, and individual differences will affect the magnetic strength, and there may be certain deviations in the sensitivity of the magnetic sensor and the relative position of the magnet, which may cause the smart gas meter to lose pulses during use, affecting Electronic Metering Function of Smart Gas Meter
