Descaling device for ultrasonic water meter

Abstract

The invention relates to the technical field of ultrasonic water meters, in particular to a descaling device for an ultrasonic water meter. The descaling device comprises a water flow pipeline and a disc partition plate, a rotating rod is fixedly mounted in the middle of the disc partition plate through a rotating shaft, and a first lantern ring is fixedly mounted at the designated position of theouter side of the rotating rod in a sleeving manner. Spiral blades are evenly and fixedly installed at the outer side of the first lantern ring, first connecting rods are fixedly installed at the twosides of the outer surface of the rotating rod, the outer side of the rotating rod is sleeved with a cylindrical cleaning brush cylinder, and a descaling filter screen is fixedly installed at the designated position in the water flow pipeline. By arranging the rotating rod, the first lantern ring, the spiral blades, the first connecting rods, the cylindrical cleaning brush cylinder and the descaling filter screen, the spiral blades drive the rotating rod to rotate under the impact of water flow, so that the cylindrical cleaning brush cylinder removes dirt on the inner wall of the water flow pipeline, and then the dirt is filtered and blocked at one side by the descaling filter screen; and the metering efficiency of an ultrasonic water meter body is improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic water meters, in particular to a descaling device 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 countercurrent in water, and analyzes and processes the flow velocity of water to further calculate the flow of water. Its characteristics are: low initial flow velocity , wide range ratio, high measurement accuracy and stable operation, no moving parts and no blocking elements inside, not affected by impurities in water, and long service life. The output communication function is complete, meeting various communication and wireless networking requirements. Ultrasonic water meters have excellent small flow detection capabilities, which can solve many problems of traditional water meters. It has a broad market and a...

Problems solved by technology

[0004] The purpose of the present invention is to provide a descaling device for ultrasonic water meters, to solve the problem that most of the traditional ultrasonic water meters proposed in the above background technology are directly placed and installed at designated positions, and then the water flow is measured and detected. However, most ultrasonic water meters generally do not have measures to clean up the dirt. When the water flows through, the impurities are easy to scale on the inner wall of the pipe and are not easy to remove, which affects the flow rate of the water passing through the water meter, thereby affecting the accuracy of the water meter detection, making the measurement results of the ultrasonic water meter not accurate. Accurate, resulting in the need for staff to re-measure, thus wasting a lot of time and energy of the staff
