Description
Technical field
The utility model relates to wind speed and direction measuring device field, particularly, relates to a kind of ultrasonic wind speed measuring instrument.
Background technology
ultrasonic wind speed measuring instrument and ultrasonic aerovane, its principle of work utilizes ultrasound wave time difference method to realize the measurement of wind speed.Because it overcomes the intrinsic defect of mechanical type anemoclinograph well, thus normally can work round-the-clockly, muchly, be used more and more widely. it will be the strong substitute of mechanical anemometer.
The principle of work of ultrasonic aerovane utilizes ultrasound wave time difference method to realize the measurement of wind speed.The aerial velocity of propagation of sound, can and wind direction on gas velocity superpose.If hyperacoustic direction of propagation is identical with wind direction, its speed can be accelerated; Otherwise if if hyperacoustic direction of propagation is contrary with wind direction, its speed can be slack-off.Therefore, under fixing testing conditions, the speed that ultrasound wave is propagated in atmosphere can be corresponding with function of wind speed.Accurate wind speed and direction can be obtained by calculating.Due to sound wave propagate in atmosphere time, its speed is very large by the impact of temperature; Anemoscope detects two reverse directions on two passages, and therefore the impact that produces acoustic velocity of temperature is negligible.
But in area or the northerly winter of relatively severe cold, time temperature is lower, because the transmission of sound wave is very large by the impact of temperature, the value of measurement is incorrect, so normally can not use ultrasonic wind velocity indicator.In order to ensure the stability of ultrasonic wind speed measuring instrument, its seating plane is comparatively large, and in use, birds easily rest on base, affect the use of ultrasonic wind speed measuring instrument, and the accuracy of measurement of ultrasonic wind speed measuring instrument is affected.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of ultrasonic wind speed measuring instrument, and it normally can use at low ambient temperatures and not be subject to the impact of birds.
The technical scheme in the invention for solving the above technical problem is:
Ultrasonic wind speed measuring instrument, comprise control circuit board, base, 4 ultrasonic probes being arranged on the gage beam on base and being arranged on gage beam, the ultrasonic probe be oppositely arranged is positioned in same level, described base is provided with scarer, temperature sensor and heating arrangement is provided with in described ultrasonic probe, described temperature sensor and heating arrangement are all connected on control circuit board, described base are provided with azimuth mark device.The measuring principle of the utility model to wind speed and direction is same as the prior art.
As preferably, described scarer comprises over cap and is located at the screw on over cap.
As preferably, described scarer is screw, and described base is provided with mounting hole, and described screw is positioned at mounting hole.

2, the utility model arranges scarer on base, drives birds, avoids birds to rest on base.
3, base of the present utility model is provided with azimuth mark device, is convenient to the installation of ultrasonic wind speed measuring instrument, improve the measuring accuracy to wind direction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of base in embodiment 3.
Mark and corresponding parts title in accompanying drawing: 1, base; 11, mounting hole; 2, gage beam; 3, ultrasonic probe; 4, azimuth mark device.
Embodiment
Below in conjunction with embodiment and accompanying drawing, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1:
As Fig. 1 shown in a kind of ultrasonic wind speed measuring instrument, comprise control circuit board, base 1,4 ultrasonic probes 3 being arranged on the gage beam 2 on base 1 and being arranged on gage beam 2, the ultrasonic probe 3 be oppositely arranged is positioned in same level, described base 1 is provided with scarer, temperature sensor and heating arrangement is provided with in described ultrasonic probe 3, described temperature sensor and heating arrangement are all connected on control circuit board, and described base 1 is provided with azimuth mark device 4.
The utility model improves on the basis of existing technology, namely the temperature of temperature sensor to ultrasonic wind speed measuring instrument environment for use is utilized to detect, and send control circuit board to, when temperature is lower than certain value, control circuit board controls heating arrangement and heats ultrasonic probe 3, ensures the normal operation of ultrasonic probe 3; And utilize scarer to drive birds, avoid birds to rest on base.Surface level namely make a comment or criticism normal use time state.In order to improve the measuring accuracy of ultrasonic wind speed measuring instrument to wind direction, in use, must be that acoustic transformer arm is just to the north, therefore azimuth mark device 4 is provided with on base 1, accuracy when utilizing azimuth mark device 4 raising to install, namely when mounted, by azimuth mark device 4 just to the north, can not distinguish gage beam 2, be convenient to install.
Embodiment 2:
As Fig. 1 shown in a kind of ultrasonic wind speed measuring instrument, the present embodiment has done refinement on the basis of embodiment 1, and namely described scarer comprises over cap and is located at the screw on over cap.Adopt the mode of tin hat and screw to realize driveing birds, its structure is simple, is also convenient to install.During installation, directly tin hat is fixed on base.One end of screw is sharper, is kind of threats, can reaches the object of driveing birds to birds.
Embodiment 3:
As Fig. 1 and Fig. 2 shown in a kind of ultrasonic wind speed measuring instrument, the present embodiment has done refinement on the basis of embodiment 1, and namely described scarer is screw, and described base 1 is provided with mounting hole 11, and described screw is positioned at mounting hole 11.The present embodiment is the optimal enforcement example of embodiment 2, is directly arranged on base by screw, convenient, cost-saving.
