In the absence of intermediary element.Term as used herein " vertically ", " level ", "left", "right" and similar statement are
For illustrative purposes.
As depicted in figs. 1 and 2, a kind of air velocity transducer, including sensor body 100, blade 200, signal acquisition module
300th, signal processing module 400 and signal emission module 500.Sensor body 100 is provided with air channel 101.The first end in air channel 101
Provided with air outlet 102, second end in air channel 101 is provided with air inlet 103.Blade 200 is installed in air channel 101.Signal acquisition mould
Block 300 is used for the tach signal for gathering blade 200.The input of signal processing module 400 and the output of signal acquisition module 300
End connection.Signal processing module 400 is used to tach signal being converted into wind velocity signal.The input of signal emission module 500 with
The output end connection of signal processing module 400, signal emission module 500 is used to send wind velocity signal.
In above-mentioned air velocity transducer, wind enters air channel 101 from air inlet 103, blows the blade being arranged in air channel 101
200, and leave air channel 101 from the air outlet 102 in air channel 101.There is positively related relation in the rotating speed of wind speed and blade 200.Wind
Fast big, then the rotating speed of blade 200 is big.By one kind in mathematical derivation, empirical equation, experiment test or simulation calculation or two kinds with
Upper type, staff results in the corresponding relation between the rotating speed of blade 200 and wind speed.Therefore, the energy of signal processing module 400
It is enough that the tach signal of blade 200 is converted into wind velocity signal.The wind velocity signal tried to achieve is sent to monitoring by signal emission module 500
Personnel.In this way, the region wind speed information issued compared to meteorological department, above-mentioned air velocity transducer is used to be arranged on wind speed point to be measured
Position, such as electric power pylon 600, building or electric pole etc., can detect the wind speed information for obtaining particular locations, accurate
True property is good.
Specifically, blade 200 is provided with rotating shaft.Signal acquisition module 300 is by measuring the rotating speed of rotating shaft so as to obtain blade
200 tach signal.
Above-mentioned air velocity transducer is used to measure the wind load that electric power pylon 600 is subject under extreme weather.Meteorological department makes
Wind speed is measured with fan leaf type anemobiagraph.But there is deterioration in fan leaf type anemobiagraph, be easily lost by dust storm in rotation process,
Easily freezed, sleet is disturbed.And above-mentioned air velocity transducer, blade 200 is arranged in air channel 101, it is to avoid frost or sleet interference,
Strong adaptability.
Further, as shown in figure 1, being provided with weatherseal 104 at air inlet 103.Weatherseal 104 is provided with inlet section 105.Enter

In extreme weather environment without being damaged.In this way, above-mentioned air velocity transducer has good wind resistant property.
Specifically, as shown in figure 1, weatherseal 104 is deep bead.Deep bead is provided with more than one fresh air inlet.Wind is by gear
During aerofoil, due to the stop of deep bead, wind speed reduction, so that the blast at air inlet 103 is more than the blast at air outlet 102.
Due to the presence of pressure difference, wind automatically enters air channel 101 from the fresh air inlet of deep bead.
Further, staff can control the quantity of the enterprising air holes of deep bead, or control fresh air inlet unlatching or
Sealing.Such as, fresh air inlet is multiple.Seal is removably installed at fresh air inlet.One seal blocks a fresh air inlet,
Then the incoming air area of deep bead is reduced.Seal is disassembled from deep bead, then the incoming air area increase of deep bead.Compare again
Such as, deep bead is provided with rotating disk.Rotating disk is rotated, so as to block fresh air inlet, then the incoming air area of deep bead is reduced.By changing rotating disk
Rotation direction and rotational angle, then staff can reduce or increase the incoming air area of deep bead.In this way, staff
The incoming air area of deep bead can be controlled.According to the intensity of extreme weather leeward and the mechanical property of blade 200, staff changes
Become the incoming air area of deep bead, so as to change the pressure difference at the two ends of air channel 101, the intensity of the wind in air channel 101 will not damaged blade
200.Similarly, now there is one-to-one relationship in the rotating speed of blade 200 with the wind speed that steel tower is subjected to.Pass through mathematical derivation, warp
The one or two or more kinds of modes tested in formula, experiment test or simulation calculation, staff result in the rotating speed of blade 200 with
Corresponding relation between wind speed.In this way, under extreme weather, above-mentioned air velocity transducer will not be damaged, wind speed can be normally measured.
It is appreciated that weatherseal 104 can also be yarn fabric or porous member with hole, such as cloth or sponge.Enter
Wind portion 105 refers to fresh air inlet or air inlet pore.When wind passes through weatherseal 104, due to the obstruction of weatherseal 104, the speed of wind
Degree reduction, causes the two ends in air channel 101 to there is draught head.Meanwhile, wind energy is enough to enter air channel from the hole of weatherseal 104 or hole
In 101.
