Description
Technical field
The present invention relates to a kind of wind direction and wind velocity sensors.
Background technique
Air velocity transducer is the weight that can continuously monitor wind speed size, and can carry out real-time display to the wind speed of present position
Want instrument.The sensor is widely used in mine, electric power, tobacco, and medicine etc. needs the field of real-time monitoring wind speed.Wind speed sensing
What the type of device and performance directly affected systematic air flow detects and controls quality.Air velocity transducer is various in style, the most commonly used is
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 is all made of pitot tube type air velocity transducer.Existing skin
Hosted-type air velocity transducer has good precision in 4-16m/s range, but has limitation in terms of small measuring wind speed, low
It is unable to measure in 2m/s, is not available 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, key and sensor module circuitry plate, sensor module circuitry plate are installed inside the housing, display screen and are pressed
Key is installed on the shell, and detection bar is fixed by extension bar and sensor module circuitry plate, is detected and is provided with total pressure survey on the bar wall of bar
Hole is pressed, position corresponding with total pressure pressure tap is provided with static pressure pressure tap on bar wall, and a total pressure pressure tap and a static pressure are surveyed
Pressing hole is a pair of of venthole, and detecting on bar has multipair venthole.
Although it has the advantage that by the way that multipair ventilation hole is arranged, air mixing can be made more evenly, can measure 0-
Wind speed between 20m/s is particularly suitable for the measurement of 0.2~2m/s gentle breeze speed, and precision reaches 0.1m/s, has filled up Pitot tube original
The air velocity transducer of reason is not capable of measuring the blank of gentle breeze speed, keeps measured value more accurate.
But the disadvantage is that: in use, the hole face of total pressure pressure tap is vertical with airflow direction, on bar wall with total pressure pressure tap
Corresponding position is provided with static pressure pressure tap, and when use has limitation.
Chinese patent 201220738970.8 discloses a kind of air velocity transducer, comprising: shell, the shell have interior
Chamber and the first helicitic texture；Wind speed mechanism is set on the shell；Driving shaft mechanism, in the inner cavity of the shell,
And it is connect with the wind speed mechanism；Bearning mechanism is connect in the inner cavity of the shell with the inner walls, and
It is connect with the driving shaft mechanism；
Wind speed conversion circuit module, the wind set on the inner cavity of the shell, for detecting the wind speed mechanism
Speed variation is converted into digital signal output；
Power supply device connect with the wind speed conversion circuit module, and powers for it；
Base mechanism, including pedestal have the second helicitic texture cooperated with first helicitic texture on the pedestal,
The base mechanism is threaded in one with the shell to realize by the cooperation of second screw thread and first screw thread
It rises, thus by the driving shaft mechanism, the Bearning mechanism and the wind speed conversion circuit module are encapsulated in the institute of the shell
It states in inner cavity；
It is characterized by: the base mechanism is equipped with the first location structure, the shell is equipped with the second positioning knot
Structure；The sensor further includes latch positioning element；When the shell is threadedly coupled mutually with the base mechanism by described
After screwing, the latch positioning element is cooperated with first location structure and second location structure respectively, so that
Relative positioning is formed in the circumferential between the base mechanism and the shell.
Although it has the advantage that the base mechanism is equipped with the first location structure, the shell is equipped with second
Location structure；The sensor further includes latch positioning element；When the shell is connected with the base mechanism by the screw thread
It connects after mutually screwing, the latch positioning element is matched with first location structure and second location structure respectively
It closes, so that forming relative positioning in the circumferential between the base mechanism and the shell.Above-mentioned design can be in shell and pedestal
After screwing relatively, it even if shaking, will not loosen again, to influence detection accuracy, influence the work of air velocity transducer
Make reliability, this is because the two has been carried out relative positioning by latch positioning element in the circumferential.
But it is that wind speed and direction is detected by rotary part in measurement process, air velocity transducer and propeller wind
For fast sensor because gyrating mass is limited, sensor device inertia is larger, and rotating part destroys flow field, is not capable of measuring lower wind speed,
Error is larger, and service life is limited.
