Abstract
The utility model relates to a connection plate suitable for wind tunnel wind speed multi aperture calibration. The connection plate comprises a connection plate body. A number of tube seats which have different specifications and are connected with wind tunnel tubes are uniformly distributed in the middle of the connection plate. A tube cap is arranged in an upper port of each tube seat. A tube plug is inserted into an opening in the middle of each tube cap. According to the utility model, the connection plate suitable for wind tunnel wind speed multi aperture calibration is designed; the connection plate is fixed in an original wind tunnel measurement hole; the tube seats of different tube diameters are arranged on the connection plate; a backrest tube to be calibrated can be inserted into a tube seat and is fixed on a wind tunnel; each tube seat is provided with a corresponding tube plug; when any tube seat needs to be used, the tube plugs are arranged on other tube seats before a calibration test; the influence of air leakage on the test is removed; and the backrest tube can be fixed on the wind tunnel, which reduce manpower input.
Description
Technical field
The utility model belongs to engineering measuring technology field, and especially a kind of wind tunnel speed is demarcated multiple aperture and is suitable for fishplate bar.
Background technology
Wind-tunnel is usually used in the rating test to measuring wind speed instruments such as backing tubes.When rating test, backing tube to be calibrated need to be placed to wind-tunnel gaging hole place, then the place of leaking out takes cloth to block.
But traditional wind-tunnel gaging hole for the aperture that can be suitable for multiple backing tube and conventionally do very large, this is easy to during making to demarcate cause measurement result inaccurate because test period gaging hole place exists to leak out, simultaneously because backing tube cannot be fixed, in test process, need tester to hold all the time backing tube, increased manpower.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, demarcates the applicable fishplate bar of multiple aperture and propose a kind of wind tunnel speed.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of wind tunnel speed is demarcated multiple aperture and is suitable for fishplate bar, it is characterized in that: comprise fishplate bar, at the different base of the multiple specifications that are communicated with wind-tunnel pipe of the even cloth in the middle part of fishplate bar, in the upper port of each base, pipe cap is installed, at the intermediate openings place of pipe cap, connector has pipe plug.
And described multiple bases are three highly different cylindrical bases, are highly respectively 20mm, 30mm and 55mm, caliber is 60mm, and the upper port of described pipe cap and base spins.
And described multiple bases are the base of small one and large one two kinds of calibers, the large base mouth of pipe is long is 150mm, and wide is 85mm, high 30mm, and the pipe cap mating with the base mouth of pipe is fixed pipe cap by bolt, and tubule seat caliber is 50mm, high 30mm.
Advantage of the present utility model and good effect are:
The utility model has designed wind tunnel speed and has demarcated the applicable fishplate bar of multiple aperture, this fishplate bar is fixed at former wind-tunnel gaging hole place, the base of different tube diameters is housed on this fishplate bar, make backing tube to be calibrated can be screwed into base and be fixed on wind-tunnel, each base is furnished with corresponding pipe plug, in the time which base needs use, before rating test, all the other bases are loaded onto to pipe plug, so both eliminated the impact of leaking out on test, backing tube can be fixed on wind-tunnel again simultaneously, has reduced the input of manpower.

Embodiment
Below in conjunction with accompanying drawing, the utility model is implemented to be further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of wind tunnel speed is demarcated multiple aperture and is suitable for fishplate bar, as shown in Fig. 1 or 2, wind-tunnel fishplate bar 1, at the different base 2 of the multiple specifications that are communicated with wind-tunnel pipe of the even cloth in the middle part of wind-tunnel fishplate bar, in the upper port of each base, pipe cap 3 is installed, at the intermediate openings place of pipe cap, connector has pipe plug 4.
Example 1
The multiple aperture that is provided with three differing heights bases for the backing tube of different length is suitable for fishplate bar, the cylindrical base of three differing heights, highly be respectively 20mm, 30mm and 55mm, caliber is 60mm, as shown in Figure 5, when use, this fishplate bar is fixed on to the opening part of wind-tunnel pipe 7, according to suitable base on the selected suitable fishplate bar of the length of backing tube, screw the pipe cap connecting with base mouth, pull up the pipe plug at pipe cap mouth place, backing tube is inserted in wind-tunnel pipe and measured in real time.
Example 2
The multiple aperture that is provided with the base of small one and large one two kinds of calibers for the backing tube of different tube diameters is suitable for fishplate bar, the large base mouth of pipe is long is 150mm, wide is 85mm, high 30mm, the pipe cap mating with the base mouth of pipe is fixed pipe cap by bolt 5, tubule seat caliber is 50mm, high 30mm, can be according to backing tube pattern choice for use when test.
