Embodiment
Following examples are used to illustrate the utility model, but are not limited to the scope of the utility model.
Embodiment 1
As shown in Figure 1, 2, 3, the wind-force dynamic pressure harvester includes ventilation body 1, center connecting cylinder 2 and eight dynamic pressure inspections
Test tube 3, in tubular construction, ventilation body 1 is provided at both ends with flange 11 to ventilation body 1, convenient whole by setting flange 11
Wind-force dynamic pressure harvester is rapidly assembled and disassembled.Center connecting cylinder 2 has cavity structure, and center connecting cylinder 2 is placed in ventilation
On the axis of body 1, the front end of center connecting cylinder 2 is in bullet-shaped, thus substantially reduces the windage of center connecting cylinder 2 with
Heart connecting cylinder 2 influences to caused by collection result accuracy.Dynamic pressure detection pipe 3 in tubular construction, in the present embodiment, is provided with
Eight dynamic pressure detection pipes 3, naturally it is also possible to which the six roots of sensation, the dynamic pressure detection pipe 3 of ten or more are set, and eight dynamic pressure detection pipes 3 are in
Periphery that is radial and being evenly arranged in center connecting cylinder 2, one end of every dynamic pressure detection pipe 3 connect with center connecting cylinder 2, its
In a dynamic pressure detection pipe 3 the other end extend to ventilation body 1 outside and connected with pressure detector, remaining seven dynamic pressure
Another end closure of detection pipe 3 is simultaneously connected with the inwall for body 1 of divulging information, on the tube wall of the side windward of every dynamic pressure detection pipe 3
Three stagnation pressure holes 31 are provided with, i.e. the first stagnation pressure hole, the second stagnation pressure hole and the 3rd stagnation pressure hole, three stagnant
Only pressure port is located on the same line, and in order to ensure the accuracy of collection, the diameter of every dynamic pressure detection pipe 3 is identical and inwall
Smooth, the diameter of stagnation pressure hole 31 is more than 1mm, and the wind speed divulged information in body 1 is less than 85m/s.The position in stagnation pressure hole 31
Meet claimed below, the distance of the first stagnation pressure hole to the ventilation axis of body 1 be 0.479D, and the second stagnation pressure hole is to divulging information
The distance of the axis of body 1 is 0.155D, and the distance in the 3rd stagnation pressure hole to ventilation duct body axis is 0.383D, wherein, D is logical
