Ultrasonic heat meter convenient for automatic cleaning

Abstract

The invention provides an ultrasonic heat meter convenient for automatic cleaning. A module sealing box, a module box mounting rack and a flow measuring tube are included. An electronic module and a lithium battery are arranged in the module sealing box, a support mounting tube is arranged on the flow measuring tube, and a reflector support sleeves the support mounting tube; the reflector supportis connected with a reflector, a motor is further included, the shaft end of the motor is connected with a driving gear, the driving gear is connected with a driving gear set, the driving gear set isconnected with a driven gear, and an inner hole is formed in the center of the driven gear; and a worm part is arranged in the inner hole in a sleeved mode, an internal thread matched with the worm part is arranged on the inner hole, one end of the worm part is connected with the reflector, and a scraping piece is arranged above the reflector so that stains on the surface of the reflector can be removed regularly, the stains are prevented from forming precipitation and bonding on the surface of the reflector, and therefore, the product quality is improved, and the operation period are prolonged.

Description

technical field [0001] The invention relates to a heat meter measuring device, in particular to an ultrasonic heat meter which is convenient for automatic cleaning. Background technique [0002] At present, the application of ultrasonic flow measurement technology on heat meters has become more and more mature. Among them, the application of reflection is more common. It generally includes flow tubes, ultrasonic reflectors, ultrasonic reflectors, and metering devices. Among them, there are mainly two types of ultrasonic reflectors. , one is to install a mirror in the flow tube, and use the mirror to reflect ultrasonic waves; the other is to use the inner wall of the flow tube to reflect. Ultrasonic heat meters are widely used in the heat metering and charging of the heating system in northern my country. Due to the circulating water used in the heating system pipes, and the water quality in some areas is hard, the heating system does not operate in summer, and the water trea...

AI Technical Summary

Problems solved by technology

Ultrasonic heat meters are widely used in the heat metering and charging of the heating system in northern my country. Due to the circulating water used in the heating system pipes, and the water quality in some areas is hard, the heating system does not operate in summer, and the water treatment of the pipes is in a static state. Therefore, during use In the ultrasonic heat meter, the measurement accuracy of the meter is often affected by the adhesion of dirt on the reflection sheet of the ultrasonic heat meter, and even the measurement cannot be performed. Although the reflector is detachable now, the reflector can be removed for cleaning when necessary, but the reflector The disassembly and assembly are complicated, and the on-site operation is difficult, and the on-site disassembly and assembly of the reflector will also affect the measurement accuracy of the product, and the product needs to be re-inspected
