Abstract
The utility model discloses a device used for measuring wind speed and wind direction, belonging to the technical field of meteorological detection. The device comprises a Pitot tube, a wind vane and a micro differential pressure sensor. The Pitot tube is used as a wind measuring probe, and the high-precision digital micro differential pressure sensor and the wind vane are used for wind speed measuring. The Pitot tube cooperates with the wind vane, the Pitot tube always directly faces the wind speed by relying on rotation of the wind vane, thereby guaranteeing accurate measuring of the wind speed. The device is good in instantaneity, high in precision, low in cost and good in reliability, and can be hardly influenced by the environment.
Description
Technical field
The utility model relates to the device of measuring wind, wind direction, belongs to meteorological detection technique field.
Background technology
Wind speed is the important component part of meteorological observation, and daily life and industrial and agricultural production all have close contact with wind.Wind speed, wind direction be measured as weather forecast accurately and early warning provides data, for the generaI investigation and the utilization of wind energy provides service.
At present, vane commonly used and ultrasonic wind speed meter carry out measuring wind speed in the weather station.Weathervane and vane are used.The vane wind gage is by the revolution calculation of wind speed of vane in a period of time, it is big to start wind speed, sluggish big, can't measure instantaneous wind speed, freezing sleety weather influences the rotation of vane and produces bigger error, the long-time mechanical wear that causes of rotating also can influence the measuring wind speed precision, and its serviceable life is shorter; And the ultrasonic wind speed meter has the price height, is subject to stopping of precipitation snowfall and influences defectives such as measuring accuracy.
Summary of the invention
Technical problem to be solved in the utility model is the defective at above background technology, and the device of a kind of measuring wind, wind direction is provided.
The utility model is for solving the problems of the technologies described above by the following technical solutions.
A kind of device that is used for measuring wind, wind direction, comprise pitot tube, weathervane, pressure transducer, be installed on the base by rotation axis after wherein weathervane is fixedlyed connected with pitot tube, described pressure transducer is installed in the top of pitot tube, be used to respond to the pressure differential of pitot tube total head and static pressure, and the numerical value of output measuring wind speed.
Preferably, the device that is used for measuring wind, wind direction of the present utility model, pressure transducer adopts the high-precision digital little differential pressure sensor.
Preferably, the device that is used for measuring wind, wind direction of the present utility model, pitot tube are the L type, and the one end is an air inlet, and the other end is connected with pressure transducer up.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
The utility model adopts pitot tube at measuring wind speed, is realized the measurement of wind direction in the high-acruracy survey that realizes wind speed by weathervane.The utility model uses high-precision little differential pressure sensor to carry out measuring wind speed, has that real-time is good, precision is high, characteristics such as good reliability, cost are low, has to be subjected to sleet, weather conditions such as freezing to influence less advantage.
Description of drawings
Fig. 1 is a structure drawing of device of the present utility model.
Number in the figure is explained: 1-pitot tube, 2-pressure transducer, 3-weathervane, 4-rotation axis, 5-static pressure, 6-total head.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail.
As shown in Figure 1, the device of a kind of measuring wind, wind direction comprises pitot tube 1, weathervane 3, pressure transducer 2.Wherein the total head 6 and static pressure 5 of pitot tube output are connected to pressure transducer; Pitot tube, pressure transducer are installed on the weathervane.
Pitot tube:, can adopt common gas flow rate pitot tube as the measuring wind speed probe.
Pressure transducer: adopt the high-precision digital little differential pressure sensor, be installed in the top of pitot tube, total head that pitot tube produces during by measuring wind speed and static pressure are as the input of digital little differential pressure sensor, and, be converted into air speed value through the processing of internal circuit and microprocessor according to the size of force value.
Weathervane: be used to detect wind direction, be fixedly mounted on the rotation axis 4 after weathervane and pitot tube are combined integrated.During measurement, the wind speed measuring device that pitot tube and high-precision digital little differential pressure sensor are formed can the box haul mark and is rotated, and makes the total head mouth of pitot tube all the time over against wind speed direction, has guaranteed the correct measurement of wind speed.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
