With bearing as boundary, 331 points of Pitot tube is two parts, and a portion of Pitot tube 331 is located in cavity, and is passed through
The through hole of the intersection of support member 3115, bearing causes Pitot tube 331 to fix, it is to avoid right caused by one end of Pitot tube 331 is sagging
The destruction of seal.The another part of Pitot tube 331 is located at outside cavity, for detecting blast.
Pitot tube 331, also known as pitot, Pitot-static tube, are the one kind for measuring air-flow stagnation pressure and static pressure to determine air velocity
Tube, is invented by Frenchman's H. skins support and is gained the name.Strictly speaking, Pitot tube 331 only measures air-flow stagnation pressure, also known as stagnation pressure
Pipe；Simultaneously measure stagnation pressure, static pressure and just claim Pitot-static tube, but traditionally many Pitot-static tube is referred to as Pitot tube 331.
Signal processor 333 is used to detecting the blast information that Pitot tube 331 detects and the information is processed, Pi Tuo
Connected by signal transmssion line between pipe 331 and signal processor 333.Signal processor 333 can be non-dismountable using welding etc.
Mode be fixed on cover body 313 or bracing frame 311, it is also possible to be detachably secured to bracing frame 311, in the present embodiment, letter
Number processor 333 is rectangular-shape, and signal processor 333 is fitted and be bolted with tingle 3115A.
Pitot tube 331 measures the principle of wind speed：Head is aligned to flow when testing the speed, aperture (pitot hole) sense at head center
To flow stagnation pressure p0, Jing inner tubes are sent to pressure gauge.A round is equably provided with overcoat tube wall after head at about 3～8D
(baroport), experiences to flow static pressure p, and Jing outer tubes also reach pressure gauge.For potential flows, according to Bernoulli equation and
Energy equation can obtain gasflow mach number, and then seek speed again.Pitot hole has certain area, and what it was experienced is near stationary point
Average pressure, slightly below stagnation pressure, the static pressure of baroport impression also has certain error, and other also have error as manufactured, installing, therefore
Should add a correction factor ζ during measuring and calculating flow velocity.ζ values are corrected typically in the range of 0.98～1.05 in the air-flow of known speed
Or Jing standard pitot tubes 331 are corrected and determined.The simple structure of Pitot tube 331, it is easy to use, have many uses.
It is prior art that the blast information of Pitot tube 331 is converted to wind speed information by signal processor 333, and here is no longer gone to live in the household of one's in-laws on getting married
State.
In addition to strengthening the intensity of cover body 313, another effect of bracing frame 311 is for supporting measuring wind speed part
33, naturally it is also possible to which measuring wind speed part 33 is directly installed on cover body 313.
The operation principle of above-mentioned wind speed measuring device 03 is：Wind speed measuring device 03 is installed on into wind-driven generator (in reality
Apply and do not embodied in example 1) on, airflow passes cover body 313 and Pitot tube 331, air-flow applies certain blast, skin to Pitot tube 331
Wind pressure signal is passed to signal processor 333 by trustship 331, and signal processor 333 is processed wind pressure signal, and by blast
Signal output is wind speed information.
Embodiment of the present utility model 1 measures the wind speed on wind-driven generator using Pitot tube 331, disturbs less, essence
Degree is very high, also, simple structure, use cost are relatively low, and Pitot tube 331 can follow kuppe 31 to rotate, not-easy-to-freeze, make wind
Speed measuring device 03 can adapt to more rugged environment.
Embodiment 2：
Corresponding, as shown in fig. 6, the utility model embodiment 2 additionally provides a kind of wind-driven generator 100, the wind-force is sent out
Motor 100 includes the wind speed measuring device 03 described in engine room cover top 01 and embodiment 1.
Jing applicant has found that the wind speed measured by existing measuring wind speed instrument is deposited with the wind speed of reality in real work
In larger deviation, through long-term research, test, applicant have found the reason for causing the problem, i.e. air-flow and passes through finally
Wind energy is absorbed during wind wheel so that wind speed decreased, and turbulivity also changes therewith, causes measurement data with real data not
Symbol.In order to improve the problem, the embodiment of the present application 2 provides a solution, and wind speed measuring device 03 is arranged on into cabin
On cover top 01, also, wind speed measuring device 03 is located at the front end of wind wheel, and wind speed measuring device 03 can directly be surveyed in wind wheel front end
Amount wind speed, it is to avoid wind wheel is interfered to wind speed, and measurement data is more accurate.
It should be noted that in the case where not conflicting, the feature in embodiment in the utility model can be tied mutually
Close.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
