Spliced anti-electromagnetic interference protection mechanism for ultrasonic water meter

Abstract

The invention relates to the technical field of ultrasonic water meters, in particular to a spliced anti-electromagnetic interference protection mechanism for an ultrasonic water meter. The spliced anti-electromagnetic interference protection mechanism comprises an ultrasonic water meter body and a protection mechanism on the outer wall of the ultrasonic water meter body, the protection mechanismat least comprises two mutually-symmetrical protection shells, the two protection shells are connected and fixed through bolts, each protection shell is in an inverted T-shaped metal shell shape, attaching plates are arranged at the two ends of each protection shell, and rubber rings are arranged on the inner walls of the attaching plates; and rubber blocks are arranged at the two ends of the attaching plates correspondingly, and connecting external threads are arranged on the outer wall, close to the top, of each protection shell. When the protection shells are specifically used, the two protection shells are combined together to cover the periphery of the ultrasonic water meter body, the rubber blocks are located between the two protection shells, and it can be guaranteed that the two protection shells are connected more tightly; and according to the spliced anti-electromagnetic interference protection mechanism, the outer wall of the ultrasonic water meter can be protected, the influence of electromagnetic interference is effectively shielded, and disassembly and assembly are convenient.

Description

technical field [0001] The invention relates to the technical field of ultrasonic water meters, in particular to a spliced ​​anti-electromagnetic interference protection mechanism for ultrasonic water meters. Background technique [0002] Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change of velocity when the ultrasonic sound beam propagates downstream and upstream in water, analyzes and processes the flow velocity of water, and then further accumulates the flow of water. Its characteristics: low initial flow velocity, Wide range ratio, high measurement accuracy and stable operation. There are no moving parts and flow-blocking elements inside, not affected by impurities in the water, and have a long service life; the output communication functions are complete, meeting various communication and wireless networking requirements, with excellent small flow detection capabilities, and can solve many problems of traditional w...

Problems solved by technology

[0003] During the use of ultrasonic water meters, it is susceptible to electromagnetic interference. Electromagnetic interference is due to the electromagnetic harmonics generated during the operation of the equipment itself, or the electromagnetic harmonics generated by its surrounding equipment during the operation. The existence of these electromagnetic harmonics, It may cause the equipment to fail to work normally. In the case of serious electromagnetic harmonics, it will cause damage to the equipment. However, the outer wall of the current ultrasonic water meter has no protection mechanism, which is very susceptible to electromagnetic interference and affects the service life. In view of this, We propose a spliced ​​anti-electromagnetic interference protection mechanism for ultrasonic water meters
