Abstract

The invention discloses a tunnel ultrasonic wind speed and direction detector, which comprises an outer shell, an inner shell and an ultrasonic probe, and is characterized in that the ultrasonic probeis arranged on a top plate of the inner shell; the inner shell is provided with a mounting cavity and sleeved with the outer shell, a flowing cavity is formed between the outer shell and the inner shell, a first air hole is formed in one side face of the outer shell, a second air hole is formed in one side face of the inner shell, the first air hole and the second air hole are both communicated with the flowing cavity, the second air hole is communicated with the mounting cavity, and the air inlet direction of the first air holes is perpendicular to that of the second air holes. According tothe tunnel ultrasonic wind speed and direction detector provided by the invention, a gas circulation cavity is formed between the inner shell and the outer shell, so that external gas and gas in the inner shell can be exchanged conveniently, a circuit board in the mounting cavity can be cooled conveniently, and the detection precision is further ensured; and the air inlet directions of the first air holes and the second air holes are vertical, so that external rainwater is prevented from immersing into the mounting cavity in rainy days.

Description

technical field [0001] The invention relates to the technical field of tunnel environment detection equipment, in particular to a tunnel ultrasonic wind speed and direction detector. Background technique [0002] In the safety inspection of the tunnel, the wind speed and wind direction in the tunnel are important environmental indicators. The ultrasonic wind speed and direction detector is used in the wind speed detection and wind direction detection of the tunnel, which can improve the environmental detection efficiency in the tunnel. A general tunnel ultrasonic wind speed and direction detector includes a shell, a circuit board, an ultrasonic probe, etc. The circuit board is set in the shell, and the ultrasonic probe is set on the shell. Generally, the shell is a closed shell. Work or circuit failure on the circuit board leads to high temperature of the circuit board, which affects the work of electrical components, thereby affecting the detection accuracy.
