Description
Technical field
The utility model relates to a kind of speed measuring Instrument, in particular to a kind of wind speed and direction measuring instrument.
Background technique
Current wind speed and direction measuring instrument belongs to big machinery, although can satisfy high-precision requirement, not
It is good to carry, and complexity is installed, so a kind of wind speed and direction measuring instrument satisfaction of small volume is needed to be convenient for carrying outdoor survey
The requirement of amount.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts and deficiency, wind direction can be measured simultaneously by providing one kind
With the measuring instrument of wind speed, the measuring instrument volume is less, and structure is simple, easy to carry.
The purpose of this utility model passes through a kind of following technical proposals reality: wind speed and direction measuring instrument, including axle center is through-hole
Circular furnace shape mounting disc, be evenly distributed several mounting grooves on the periphery of the mounting disc, wherein mounting groove all with it is logical
Hole is connected to, and is equipped with impeller in the mounting groove, is equipped with gear on the axis of impeller, has one with what the clearance between gear teeth of gear cooperated
A magnetic impulse type speed probe, the magnetic impulse type speed probe include permanent magnet, soft magnetic core, coil and non-magnetic
Shell, the quantity of the soft magnetic core are two, and permanent magnet is arranged between two soft magnetic cores, and coil surrounds outside soft magnetic core
It enclosing, the soft magnetic core is connect with shaping amplifier, and the shaping amplifier is connect with frequency/voltage conversion circuit, the frequency/
Voltage conversion circuit is connected with microprocessor.
Preferably, the quantity of the gear teeth in the gear is N number of, N >=4, the voltage signal values and wind speed pair that impeller generates
The relationship answered are as follows: V=Z*60/N+W.
Preferably, it is fixed in mounting groove on the axis of the impeller by support rod, support rod and axis corresponding position are equipped with axis
It holds.
The utility model on the periphery of mounting disc compared with the existing technology have following advantages and effects be evenly distributed
Several mounting grooves, the rotation blowed air over the impeller in mounting groove can be caused in each direction, revolving speed pass through magnetic arteries and veins
The measurement of formula speed probe is rushed, after through over commutation and being transformed into voltage signal, microprocessor calculates the revolving speed of each impeller
And maximum value therein is taken, to confirm impeller location by voltage max and obtain wind speed and direction, entire measuring instrument knot
Structure is simple, easy to carry, and can guarantee the accuracy of measurement.
Detailed description of the invention
Fig. 1 is the perspective view of wind speed and direction measuring instrument.
Fig. 2 is the schematic diagram of internal structure of wind speed and direction measuring instrument.
Fig. 3 is the amplified cross-sectional view of I in Fig. 2.
Specific embodiment
The present invention will be further described in detail with reference to the embodiments and the accompanying drawings, but the implementation of the utility model
Mode is without being limited thereto.
- Fig. 3 referring to Fig.1, a kind of wind speed and direction measuring instrument, the mounting disc 2 including the circular furnace shape that axle center is through-hole 1, institute
It states and is evenly distributed several mounting grooves 3 on the periphery of mounting disc 2, wherein mounting groove 3 is all connected to through-hole 1, and wind is from arbitrary
Mounting groove 3 is come in, and is then gone out from through-hole 1.Impeller 4 is installed in the mounting groove 3, gear 7 is installed on the axis 5 of impeller 4,
With the magnetic impulse type speed probe 6 that has of 71 clearance fit of the gear teeth of gear 7, the magnetic impulse type speed probe includes
Permanent magnet 61, soft magnetic core 62, coil 63 and non-magnetic shell 64, the quantity of the soft magnetic core 62 are two, permanent magnet
61 are arranged between two soft magnetic cores 62, and coil 63 surrounds 62 periphery of soft magnetic core, and the soft magnetic core 62 connects with shaping amplifier 8
It connects, the shaping amplifier 8 is connect with frequency/voltage conversion circuit 9, the frequency/voltage conversion circuit 9 and microprocessor 10
It is connected.When the axis 5 of impeller 4 rotates, the tooth tops of the gear teeth 71 of gear 7, tooth paddy are alternately across causing the magnetic flux in coil 63
Alternately change, so that coil 63 is induced a series of pulse signals, since this pulse signal is weaker, waveform is undesirable, so wanting
Pulse signal is made a gift to someone shaping amplifier, so that it is converted into the rectangular wave for having higher magnitude of same frequency, then rectangular wave is passing through
Overfrequency/voltage conversion circuit 9 is transformed into voltage signal.The quantity of the gear teeth in the gear be it is N number of, N >=4, impeller generate
Voltage signal values relationship corresponding with wind speed are as follows: V=Z*60/N+W.Voltage signal is transmitted to microprocessor 10, microprocessor 10
Judge the voltage signal that each impeller 4 generates, wherein the impeller 4 that maximum voltage signal generates, position is then to face wind
To position, wind speed is represented as wind speed at that time, so that wind direction, wind speed determine simultaneously.
Preferably, it is fixed in mounting groove 3 on the axis 7 of the impeller 4 by support rod 11, support rod 11 and axis corresponding position
Equipped with bearing 12.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiments of the present invention is not by above-mentioned
The limitation of embodiment, it is made under other any spiritual essence and principles without departing from the utility model to change, modify, replacing
In generation, simplifies combination, should be equivalent substitute mode, is included within the protection scope of the utility model.
