The present disclosure belongs to the technical field of the combustion heating stove, and disclosed is a stove including a stove body, an air inlet channel and an exhaust channel. When the stove body is used in an enclosed space, an air inlet end of the air inlet channel is in communication with an outside of the enclosed space, a connection end of the air inlet channel is in communication with an air inlet of the stove body, the air inlet channel is operative to introduce air into the stove body from the outside of the enclosed space; and a connection end of an exhaust channel is in communication with an exhaust port of the stove body, an exhaust end of the exhaust channel is in communication with the outside of the enclosed space, whereby the exhaust channel is operative to discharge exhaust gas in the stove body out of the enclosed space.

Stove

A device and a method for detecting main acoustic indexes of multi-beam sonar pertaining to the field of hydrographic surveying and charting technology. The device includes a rotating device and a lifting gear installed in an anechoic tank. The bottom of the rotating device is equipped with a multi-beam sonar that has its rotating plane perpendicular to the direction of track line and transmits signals along the horizontal direction. A standard hydrophone is equipped at the bottom of the lifting gear, and is connected with a signal collector. The device utilizes the standard hydrophone to receive the pulse signals transmitted by the multi-beam sonar and employs the multi-beam sonar to receive the standard sound source signals, designs the detection process for data collection for analysis and research, thereby achieving the detection of the frequency, source level and beam angle of multi-beam sonar.
