A processing circuit board is arranged in the supporting cylinder, a barometric pressure sensor is arranged at the bottom of the installation disk, the four ultrasonic wave probes are installed at the same horizontal plane, two of the ultrasonic wave probes are opposite to each other and sequentially adjacent to form an inclined angle at 90 degrees, the vertical distance between each probe and the top cover is equal, each probe and the instrument installation disk form an inclined angle at 45 degrees, and the processing circuit board is arranged in the supporting cylinder. The ultrasonic wave anemometer can conduct accurate calculation for measurement of three-dimensional wind speed and wind direction, does not have movable mechanical devices, is provided with a heating device, does not need to be maintained frequently, and can be applied to allweather measurement of the wind speed and the wind direction under severe environment conditions.
Description
Technical field
The utility model relates to the wind speed and direction fields of measurement, is specifically related to a kind of ultrasonic wind speed and direction instrument.
Background technology
The most frequently used anemoclinograph mainly comprises mechanical anemometer and traditional ultrasonic wind speed instrument at present.Wherein, mechanical anemometer mainly is to obtain wind speed and direction information by rotor wheel, but there are rotatable parts in this anemoscope, and it is not suitable for wind sand environment and aging, icing phenomenon is difficult to overcome, and very big use limitation is arranged; Another kind is exactly traditional ultrasonic wind speed and direction instrument, its shortcoming mainly is that its gage beam that ultrasonic probe is installed is easy to be collided and produces certain type and becomes, thereby influence measurement result, on the other hand, what the conventional ultrasonic wave anemoscope was measured is relative wind velocity, the size that can not reflect wind energy really the utility model proposes a kind of anemoclinograph that is applicable to wind-power electricity generation.
The utility model content
In view of the above deficiency of prior art, the utility model aims to provide a kind of structural safety and reliably is applicable to the employed anemoclinograph of wind power plant.
The purpose of this utility model realizes by following means.
A kind of ultrasonic wind speed instrument, mainly by top cover, four instrument mounting discs with ultrasonic probe of the function of transmitting and receiving are installed, are connected the instrument mounting disc and install and fix support tube between dish, be connected support column between top cover and the instrument mounting disc etc. and form; The treatment circuit plate is arranged in the support tube; The bottom of mounting disc is provided with baroceptor; The adjacent relatively successively in twos one-tenth 90 degree angles of described four ultrasonic probes are installed on the same surface level; Each probe all equates with the vertical range of top cover, and with the instrument mounting disc in angle of 45 degrees; The treatment circuit plate is arranged on support tube inside.
The utility model is propagated the needed mistiming by measuring four (two pairs) ultrasonic emitting/receiving transducers along positive and negative both direction in the air, calculates relative wind velocity earlier, thereby obtains true wind velocity by the measurement to ambient pressure again.The utility model has solved the shortcoming that there are rotatable parts in the mechanical type anemoclinograph, the gage beam that has also solved simultaneously the conventional ultrasonic wave anemoclinograph is subjected to the shortcoming of physical damage easily, and has also solved the not limitation of energy measurement true wind velocity of traditional anemoclinograph.
Description of drawings is as follows:
Fig. 1 is the utility model anemoclinograph general structure synoptic diagram.
Fig. 2 is four ultrasonic probes seeing from instrument mounting disc overhead view positioned opposite figure in twos.
Fig. 3 is the utility model anemoclinograph systematic schematic diagram.
Embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further described.But should be emphasized that following embodiment is exemplary, rather than in order to limit scope of the present utility model and application.
As seen from Figure 1, the utility model mainly by top cover 1, be equipped with four ultrasonic probes 201,202,203 with the function of transmitting and receiving and 204 instrument mounting disc 3, be connected the instrument mounting disc and install and fix 4 on dish support tube 5, be connected support column 6 between top cover and the instrument mounting disc etc. and form; The treatment circuit plate is arranged in the support tube 5; The bottom of instrument mounting disc is provided with baroceptor 8.In conjunction with Fig. 2 can see four ultrasonic probes in twos relatively (as among the figure 201 with 202 two ultrasonic probes constitute one or two liang relative, two other probe 203 and 204 constitutes one or two liang relatively) adjacently successively become 90 to spend angles and be installed on the same surface level; Each probe all equates with the vertical range of top cover, and with the instrument mounting disc in angle of 45 degrees; The treatment circuit plate is arranged on support tube 5 inside, and 10 is the RS485 bus interface.For avoiding wind and snow to block the accuracy that influence is measured, the bottom of top cover and ultrasonic probe bottom are respectively arranged with heating plate 11 and 12.
Fig. 3 is the utility model anemoclinograph systematic schematic diagram, described wind speed wind direction sensor system comprises: ultrasonic drive circuit, timing unit (totally four), power supply unit, data acquisition process unit, data interface unit, described anemoclinograph four ultrasonic probes in the course of the work can receive ultrasonic signal from the probe on opposite, by measurement, thereby calculate wind speed and direction information to ultrasonic propagation time.
In order to obtain better mechanical strength and antijamming capability, what adopt aspect Machine Design is magnalium, and it has the intensity height, and anti-electromagnetic interference capability is strong, and thermal conductivity is good.In the manufacture process of reality, guarantee that each probe and the angle of instrument mounting disc are 45 degree, and want the strict distance of calculating top cover to probe, can receive the ultrasonic signal that the other side sends fully to guarantee two relative probes.
The frequency of four ultrasonic emitting/receiving transducers that adopted in the present embodiment is ultrasonic sensors of 200KHz, and this ultrasonic sensor is a transceiver, has so promptly saved the complexity that cost has reduced design again and made.
Claims (2)
1. ultrasonic wind speed instrument, it is characterized in that, mainly by top cover, four instrument mounting discs with ultrasonic probe of the function of transmitting and receiving are installed, are connected the instrument mounting disc and install and fix support tube between dish, be connected support column between top cover and the instrument mounting disc etc. and form; The treatment circuit plate is arranged in the support tube; The bottom of mounting disc is provided with baroceptor; The adjacent relatively successively in twos one-tenth 90 degree angles of described four ultrasonic probes are installed on the same surface level; Each probe all equates with the vertical range of top cover, and with the instrument mounting disc in angle of 45 degrees.
