Portable sound wave temperature measuring device

Abstract

The invention discloses a portable sound wave temperature measuring device. The device comprises a body with a hollow structure, a first part and a second part, wherein a sound wave generator is arranged in the body, and the sound wave generator is communicated with a hollow part of the body; the first part is connected to an open end of the body and is provided with a cavity in which a sound wave receiver is mounted, and the cavity is communicated with the hollow part of the body; the second part is connected to a closed end of the body and internally provided with a channel, an input end of the channel is used for being connected with an air source, and an output end of the channel is connected with a sound generator; the first part forms a first grip for external hand holding on the body, and the second part forms a second grip for external hand holding on the body. The portable temperature measuring device is simple in structure and convenient to use, and the portable design is creatively carried out on the temperature measuring device. On the hand-held structure, in order to reduce redundant structures, necessary components (a sound wave receiver, a gas delivery pipe and a mounting structure thereof) of the temperature measuring device are used as a hand-held grip.

Description

technical field [0001] The invention relates to the technical field of sound wave temperature measuring devices, in particular to a portable sound wave temperature measuring device. Background technique [0002] Acoustic temperature measurement technology has been widely used in the measurement of boiler furnace temperature field, which is of great significance to boiler combustion optimization. With the development of industrial technology and people's living standards, higher requirements are put forward for the acquisition of temperature information of some space temperature fields. The fixed online measurement method requires complex and cumbersome fixing and installation. [0003] In the prior art, there are two kinds of sound wave temperature measuring devices used in boiler temperature measurement; one is to use electric speakers and wave guides to cooperate with electrical components such as computers and sensors. The advantage of this structure is that all componen...

AI Technical Summary

Problems solved by technology

The disadvantage is that it has an open inner cavity (for sound transmission and reception) as a whole, which is easily affected by the dust in the boiler

Therefore, this type of device is generally equipped with multiple scavenging mechanisms for blowing out the internal dust, such as the published Chinese invention patent: CN106680368B; The device and multiple scavenging mechanisms all need the support of the air source, so the volume of the air source is required to be large, and usually only a fixed installation structure can be used

[0005] To sum up, the existing acoustic wave temperature measurement devices are mainly fixed and online measurement, which need to be connected with complex external power supply, air source, purging and other power and auxiliary equipment, and need to rely on industrial computer for calculation and human-computer interaction. Or computer, unable to do hand-held, fast and easy measurement
