Description
Technical field
The present invention relates to a kind of lightweight wind direction and wind velocity sensor.
Background technology
Air velocity transducer be can continuous monitoring wind speed size, and the weight of real-time display can be carried out to the wind speed of present position
Want instrument.The sensor is widely used in the field that the needs such as mine, electric power, tobacco, medicine monitor wind speed in real time.Wind speed senses
The type of device directly affects detection and the control quality of systematic air flow with performance.Air velocity transducer is various in style, most commonly
Pitot tube type air velocity transducer, ultrasonic wave vortex air velocity transducer, propeller air velocity transducer and hot line, hot diaphragm type wind speed pass
Sensor etc..At present, the air quantity variable end device of China and American-European each producer uses pitot tube type air velocity transducer.Existing skin
Hosted-type air velocity transducer has good precision in 4-16m/s scopes, but has limitation in terms of small measuring wind speed, low
It can not measure in 2m/s, can not be used in the measurement occasion of some small wind speed.
Chinese patent 201520608389.8, a kind of disclosed micro- air velocity transducer, including shell, hollow detection bar,
Extension bar, display screen, button and sensor module circuitry plate, sensor module circuitry plate are installed inside the housing, display screen and pressed
Key is arranged on shell, and detection bar is fixed by extension bar and sensor module circuitry plate, detects and total head survey is provided with the bar wall of bar
Hole is pressed, the position corresponding with total head pressure tap is provided with static pressure pressure tap, a total head pressure tap and a static pressure survey on bar wall
Pressure hole is a pair of passages, and detecting on bar has multipair passage.
Although it has advantages below：By setting multipair air vent, air mixing can be made evenly, measurable 0-
Wind speed between 20m/s, the measurement for 0.2~2m/s gentle breezes speed that is particularly suitable for use in, precision reach 0.1m/s, have filled up Pitot tube original
The air velocity transducer of reason can not measure the blank of gentle breeze speed, make measured value more accurate.
But its shortcoming is：In use, the hole face of total head pressure tap is vertical with airflow direction, on bar wall with total head pressure tap
Corresponding position is provided with static pressure pressure tap, has limitation during use.
Chinese patent 201220738970.8, a kind of air velocity transducer is disclosed, including：Housing, the housing have interior
Chamber and the first helicitic texture；Wind speed mechanism, on the housing；Driving shaft mechanism, in the inner chamber of the housing,
And it is connected with the wind speed mechanism；Bearning mechanism, in the inner chamber of the housing, it is connected with the inner walls, and
It is connected with the driving shaft mechanism；
Wind speed conversion circuit module, located at the inner chamber of the housing, for the wind for detecting the wind speed mechanism
Speed change is converted into data signal output；
Supply unit, it is connected with the wind speed conversion circuit module, and is its power supply；
Base mechanism, including base, there is the second helicitic texture coordinated with first helicitic texture on the base,
The base mechanism is threaded in one to realize by the cooperation of second screw thread and first screw thread with the housing
Rise, so as to by the driving shaft mechanism, the Bearning mechanism and the wind speed conversion circuit module are encapsulated in the institute of the housing
State in inner chamber；
It is characterized in that：The base mechanism is provided with the first location structure, and the housing is provided with the second positioning and tied
Structure；The sensor also includes latch positioning element；When the housing is threadedly coupled mutually with the base mechanism by described
After screwing, the latch positioning element is coordinated with first location structure and second location structure respectively so that
Relative positioning is formed in the circumferential between the base mechanism and the housing.
Although it has advantages below：The base mechanism is provided with the first location structure, and the housing is provided with second
Location structure；The sensor also includes latch positioning element；When the housing is connected with the base mechanism by the screw thread
Connect after mutually screwing, the latch positioning element is matched somebody with somebody with first location structure and second location structure respectively
Close so that form relative positioning in the circumferential between the base mechanism and the housing.Above-mentioned design can be in housing and base
After screwing relatively, it even if shaking, also will not again loosen, so as to influence accuracy of detection, influence the work of air velocity transducer
Make reliability, because both have been carried out relative positioning by latch positioning element in the circumferential.
But it is to detect wind speed and direction, air velocity transducer and propeller wind by rotary part in measurement process
For fast sensor because gyrating mass is limited, sensor device inertia is larger, and rotating part destroys flow field, it is impossible to relatively low wind speed is measured,
Error is larger, and service life is limited.
