Detailed description of the invention:

Explanation for example to the design below in conjunction with the accompanying drawings.

The wind speed of nature is not at the uniform velocity, even if bigger wind be not at all be interrupted but scrape stop suddenly big or suddenly small, this complex characteristics due to wind, wind scale measurement on meteorology is generally divided into instantaneous wind speed, period mean wind speed etc., so-called wind scale is namely based on what the translational speed of air molecule i.e. wind speed in air divided, be equivalent to 0 to 8 grades of wind scale to about 18m/s by 0m/s, this is ground general wind scale scope, measures this as the hobby of non-meteorological specialty and just can meet daily need and define without sticking to strict meteorology wind scale；In order to wind speed is measured in impression the most accurately,

nullMeasuring tool must accurately should not deviate in front windward，Preferably it is installed on wind speed measuring tool to adjust the most with the wind and changes on the wind vane pointed to，The wind scale instrument of the design comprises outdoor section and indoor section，Outdoor section is based on by marking peg 1、Mark post 2、Wing plate 3、Bearing 4、Standpipe 5、On the common vane device of composition such as base 6 grade，Such as Fig. 1、Shown in Fig. 2，The left and right tube wall of the mark post 2 being in directly over the standpipe 5 of wind vane is fixedly connected with a pair arranged side by side and contour hack lever 9 vertically upward，The back side at position, hack lever stage casing、Horizontal connection one pin 19 between two hack levers，Symmetrical each horizontal device one central siphon 13 on the top of two hack levers，Retain in certain interval and central siphon all movable sleeves between two central siphons in succession balance staff 12，The centre of balance staff is criss-cross to be connected to downwards a fork 11，The upper end of fork connects the aerofoil 10 lower end connection one of a circle and is in the steel ball 8 below pin 19，Under the action of the forces of the wind，The power conference layback that aerofoil is subject to drives the steel ball 8 of fork 11 and lower end to rotate around balance staff 12，When wind slightly smaller or temporary calm time，The action of gravity of steel ball can become back again in situ，The flexible connection of the balance staff 12 in central siphon 13 well cooperation can meet this motion；Right-hand member at balance staff 12 is connected to the upper end of a metal flexible axle 7, flexible axle is passed down through mark post 2, standpipe 5, base 6 until axial trough 18 end at an indoor section that is dial plate 14 back side of the design is fixed with needle pivot 16 inner end at dial plate center and is connected, needle pivot outer end is connected to pointer 15, the most advanced and sophisticated of pointer points to scale marker 17, as shown in Figure 3, Figure 4, scale marker on dial plate is in the circle closed and is evenly distributed with 32 graduation marks, and dial plate is fixed on the wall in place of indoor convenient observation；Metallic flexible axle 7 is general and sleeve kit is installed, fixing device flexible axle two ends, sleeve pipe two ends not fixing device, the restriction effect of nationality sleeve pipe can be delivered to the other end by what the bigger torsional moment repeatedly warpage of flexible axle one end turned to, the aforesaid flexible axle of the design does not just corresponds to, due to the torsional moment of required transmission, the moment (pointer on dial plate, the resistance torque of needle pivot are the least almost can be ignored) that own wt produces very much, remains able to meet this transmission effect so without arranging supporting sleeve pipe under uncased supporting effect；nullThe weight of the size of aerofoil 10 and steel ball select can according to maximum wind velocity 18m/s be the upper limit to test setting: aerofoil 10 and steel ball 8 at the biggest wind speed effect draft link 11 upper and lower side can be changed into horizontal by upper and lower vertical configuration，After becalming because of steel ball weight effect it can be recovered original position vertically downward by deviation in situ shape and terminate under the effect of pin 19 in situ without exceeding in situ again，The i.e. activity space scope of fork is in the range of maximum 90 ° of angles，The flexible axle 7 connected with balance staff 12 also can be corresponding by the needle pivot being delivered to flexible axle lower end constant for this swing magnitude range real-time synchronization and pointer，Demonstrate same angle of oscillation，Dial plate cuts out 8 graduation marks uniformly wind speed to be marked off ascending 8 grade in the range of 90 ° of angles of circumference，32 graduation marks are the most also set in whole circumference range altogether，Convenient observation；nullThe device of wind speed is experienced in order to ensure that front is mounted on wind vane windward by aforementioned being aware of，If wind vane keeps the sensing that the wind direction of the motionless next wind in position is also the marking peg of wind vane，The wind scale mark meeting setting position on dial plate 14 easily of the wind force 0 on indoor dial plate and mensuration under this condition and premise，Such as can as shown in Figure 3 shape 0 level position is arranged on 9 o'clock position，Wind-force acts on the scale marker that also can interference-free be delivered on dial plate of angle of oscillation size that aerofoil produces，So observation learns that wind scale is also easy to simply，Very clear，But in fact wind scale determinator is placed on wind vane，What wind-engaging power effect wind vane was inevitable to rotarily drive with the wind flexible axle reverses certain angle (assume the aerofoil position the most in rotary moving in now wind scale determinator i.e. it does not have flexible axle is produced twisting action)，The needle pivot on dial plate and pointer that i.e. flexible axle and lower end thereof connect not only can be rotated, by aerofoil, the torsion produced and also suffer from the torsion that the rotation of wind vane brings，This just brings the chaotic and problem of interference to accurately transmission and the Observe and measure of wind scale，That is the pointer on dial plate (or in the case of after referring to becalm) may point to any one point without determining at certain location point in the case of calm，This situation is that objective reality is unavoidable，And on the other hand，Although there being wind vane to rotate the unfavorable interference of this factor，But after blowing wind direction can basicly stable in one direction，Pointer on dial plate should be only to be acted on by aerofoil angle of oscillation within this time period，Owing to wind is to be interrupted，Wind speed acts on the power on aerofoil and can reach maximum angular when maximum and can recover original position vertically because of the action of gravity of steel ball during interval，How many graduation marks are had just to may know that wind speed wind scale about in hunting range now by the pointer observed on dial plate，Such as，Make discovery from observation the angle of oscillation substantially 4 lattice (45° angle) of pointer on dial plate，It is determined that wind scale substantially 4 grades (wind speed is about 5-8m/s)，So just can overcome the measurement result falling the wind speed wind scale that interference factor acquirement is wanted，Reach the purpose of the design.
