When the teaching draw case is in use, the utility model discloses a gasket -mounted is in the bottom of wind -tunnel, and the ejector pin supports the roof at the wind -tunnel, increases the utility model discloses a rigidity can prevent that great wind speed is right the utility model discloses cause and tremble, remove, thereby make the utility model discloses an experimental precision is high with the accuracy, the utility model discloses still has simple structure, advantage with low costs.
Description
Technical field
The utility model belongs to technical field of civil engineering, relates to the portable wedge of a kind of wind-tunnel simulation of wind specifically.
Background technology
Before turbulence theory makes a breakthrough, the test of wind-tunnel simulation of wind is still the method solving Wind Engineering problem and generally acknowledge, conventional wind-tunnel simulation of wind test method is the passive simulation technology of wedge and roughness element combination.For accurate perception wind is to the effect of structure, general needs carry out the wind tunnel test under different wind speed, and the test wind larger time only adopt the mode be connected with wind tunnel body bottom wedge to be not enough to ensure the stability of wedge, wedge trembles, vibrate, mobilely inherently have an impact to test simulation wind field accuracy, and existing sharp base is all adopt base plate to fix, therefore it is to the poor accuracy of wind field test simulation.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides the wind-tunnel simulation of wind that a kind of structure is simple, cost is low and make the accuracy of wind field test simulation high portable wedge.
The technical solution adopted in the utility model is: the portable wedge of a kind of wind-tunnel simulation of wind, comprise plate, dividing plate, base plate and push rod windward, described plate is windward isosceles triangle, plate and divider upright are arranged on base plate in base plate windward, plate is connected with divider upright windward, and dividing plate is positioned at the middle part on the base of plate windward; The upper end of dividing plate is provided with push rod, and the upper end of push rod is provided with sleeve, and sleeve and push rod are spirally connected; Described base plate is provided with multiple through hole.
Above-mentioned wind-tunnel simulation of wind is with in portable wedge, and on described base plate, the junction of plate and dividing plate is welded with reinforcement windward, and reinforcement is made by angle steel.
Above-mentioned wind-tunnel simulation of wind, with in portable wedge, the sidewall of described sleeve is arranged with two handles.
Above-mentioned wind-tunnel simulation of wind is with in portable wedge, and described push rod comprises angle steel and round bar or steel pipe, and the lower weld of the top of angle steel and round bar or steel pipe, the upper end of round bar or steel pipe is provided with screw thread.
Above-mentioned wind-tunnel simulation of wind is with in portable wedge, and described round bar or the diameter of steel pipe are 65-73mm.
Compared with prior art, the beneficial effects of the utility model are:
When the utility model uses, base plate of the present utility model is arranged on the bottom of wind-tunnel, and push rod is supported on the roof of wind-tunnel, increases rigidity of the present utility model, can prevent from larger wind speed from causing the utility model trembling, mobile, thus make test accuracy of the present utility model and accuracy high; It is simple that the utility model also has structure, the advantage that cost is low.
