Description
Technical field
The utility model relates to a kind of shaped end comb range unit being applicable to complicated landform wind tunnel test, particularly relates to one and is applicable to the vertical pinpoint movable range unit of comb.
Background technology
For the wind field characteristic in complicated landform, generally need the fluctuating wind speed data being obtained diverse location place by wind tunnel test.Comb is one of speed measuring equipment commonly used in this type of test, and its advantage is to match with electronic scanner, can obtain the synchronous time course data of fluctuating wind speed of different spatial, and then obtains amplitude and the spectral characteristic of complicated landform Wind Field.Can find from repeatedly wind tunnel test in the past and numerical simulation result, the main region of variation of complex topography wind field and level land wind field is within the scope of a certain height boundary layer closest to ground, and the closer to ground, the intensity of variation of wind speed is larger.Locomotivity during test is often focused in traditional comb design, often ignores the accurate location of bottom measuring point on vertically, thus causes the several measuring point data in bottom to bring imponderable error.
Utility model content
In existing complicated landform during comb test wind speed, bottom comb, which floor probe often can not ensure the accurate distance on distance model ground.Because wind velocity gradient near the ground in complex topography wind field is comparatively large, measure error brought thus also will be can not ignore.Not enough for this; the utility model provides one to be applicable to the vertical pinpoint movable range unit of comb; in the wind tunnel test the being applied to complicated landform wind speed test job near the ground that this movable range unit can be flexible, easy; the accurate vertical height position ensureing bottom measuring point, to guarantee to obtain accurate test data.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
One is applicable to the vertical pinpoint movable range unit of comb, comprises horizontal fine needle, rectangle frame and slide plate; The upper and lower in the vertical direction correspondence of described rectangle frame arranges chute, described slide plate to be inserted in rectangle frame and to coordinate with slide, described horizontal fine needle be arranged on rectangle frame a side roof part and perpendicular to the side of rectangle frame, one end of described horizontal fine needle is fixed on the top of rectangle frame, and the other end level of horizontal fine needle is stretched out; The tapered structure in bottom of described slide plate, described slide plate arranges graduation mark near the side of horizontal fine needle; The length of described horizontal fine needle is 30mm, and the external diameter of horizontal fine needle is tapered to 0.2mm to the other end by 0.8mm from the one end near rectangle frame.
As a kind of preferred version of the present utility model, described chute is strip; The width of described slide plate is 20mm.
Technique effect of the present utility model is: when using this movable range unit, horizontal thin pin is inserted probe termination, bottom, slide plate is slide downward in chute, make the earth surface of the bottom of slide plate and complicated landform, graduation mark from the slide plate that top chute is corresponding directly reads the height on distance ground, the relative ground of probe on comb is accurately located, and this device can in the landform of different gradient the height on measuring distance ground, thus accurately obtain the air speed data in wind tunnel test.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, one is applicable to the vertical pinpoint movable range unit of comb, comprises horizontal fine needle 1, rectangle frame 2 and slide plate 3.The upper and lower in the vertical direction correspondence of rectangle frame 2 arranges chute 4, as shown in Figure 2.Slide plate 3 to be inserted in rectangle frame 2 and to be slidably matched with chute 4, and horizontal fine needle 1 is arranged on a side roof part of rectangle frame 2 and perpendicular to the side of rectangle frame 2, one end of horizontal fine needle 1 is fixed on the top of rectangle frame 2, and the other end level of horizontal fine needle 1 is stretched out.The tapered structure in bottom of slide plate 3, slide plate 3 arranges graduation mark 5 near the side of horizontal fine needle 1, as shown in Figure 3.The length of horizontal fine needle 1 is 30mm, and the external diameter of horizontal fine needle 1 is tapered to 0.2mm to the other end by 0.8mm from the one end near rectangle frame 2.Horizontal fine needle 1 Main Function inserts probe bottom comb, and to obtain the locus of probe tips, horizontal fine needle 1 adopts hard metal to make, and needs to ensure that horizontal thin needle set has enough rigidity.
Chute 4 is strip, and the length of the chute 4 of strip, slightly larger than 20mm, makes slide plate 3 be inserted in smoothly in chute 4, and don't slide plate 3 can be made to rock in chute 4, and the effect of chute 4 is to ensure that slide plate 3 is vertical in the direction of vertical range finding.The width of slide plate 3 is 20mm, and slide plate 3 is made up of rigid metal sheet, and the broadband of bottom is reduced to 0 gradually by 20mm.Inserted by slide plate 3 after in chute 4, the bottom of slide plate 3 and the earth surface of complicated landform, directly can read calibration data from the graduation mark the slide plate 3 of upper end chute 4 correspondence, is the altitude information on distance ground.
Structure bottom comb generally comprises fusiform housing and stretches out the probe of housing, and the key position obtaining air speed data is the height at the center, termination of probe.Therefore determine that the key of the accuracy of test data is also just accurately to locate the actual height of complicated landform upper bottom portion probe termination.When using this movable range unit, horizontal fine needle 1 is inserted probe termination, bottom, slide plate 3 is slide downward in chute 4, make the earth surface of the bottom of slide plate 3 and complicated landform, the height on distance ground is directly read from the graduation mark the slide plate 3 of top chute 4 correspondence, the relative ground of probe on comb is accurately located, and this device can in the landform of different gradient the height on measuring distance ground, thus accurately obtain the air speed data in wind tunnel test.
This movable range unit is vertically located in order to auxiliary comb, to obtain the actual ground height of probe termination, as long as comb is located during use, horizontal fine needle 1 is inserted bottom probe, the bottom of slide plate 3 touches complicated landform ground, just directly can read the height on distance ground from the graduation mark the slide plate 3 of top chute 4 correspondence, can be simple, convenient and rapid be vertically accurately being located by comb, to improve the accuracy of test data.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
