Abstract
The invention relates to a sand laying device specially used in a wind sand environment wind tunnel simulation experiment. The sand laying device is characterized in that the height can be adjusted at will so as to meet the laying requirements of different sand layer thicknesses in the experiment. The core components comprise a handle, a segment of angle steel identical with the wind tunnel in width, and lead screws on two ends. The angle steel is used for maintaining the flatness of the sand surface. The lead screws are used for adjusting the height of the sand surface to be laid. The sand laying device has the advantages that the structure is simple, the operation is convenient, and the cost is low. In the wind sand simulation experiment, the experiment error caused by an uneven sand surface is avoided; in addition, the height of the sand surface can be adjusted at will from 10 to 20 cm, different experiment requirements are met, and reliable experiment conditions are provided for the wind tunnel simulation experiment.
Description
Technical field
The present invention relates to wind-tunnel technique field, be specifically related to a kind of wind-tunnel husky device of height-adjustable paving.
Background technology
Wind tunnel simulation experiment is by one of important means of blown sand physics theoretical research and Engineering of sand control practical studies, formation and the development of sand ripple, dust storm prevention and cure project protective benefits research etc. in, tool plays a very important role. In above-mentioned simulation experiment, result is had material impact by the initial form of Shamian Island. In order to avoid the Shamian Island form out-of-flatness impact on experimental result, it is desirable to Shamian Island can be allowed in the husky process of paving to keep smooth with close to desirable experiment condition.
Summary of the invention
It is an object of the invention to for deficiency of the prior art, it is provided that the husky device of the height-adjustable paving of a kind of wind-tunnel.
For achieving the above object, the invention discloses following technical scheme:
The husky device of the height-adjustable paving of a kind of wind-tunnel, including angle steel, screw mandrel and handle:
Angle steel, is used for keeping Shamian Island smooth, is provided with through hole at angle steel two ends, is welded with nut inside through hole, and nut is vertical with the one side of angle steel perforate;
Screw mandrel, is used for regulating the Shamian Island height needing to lay, totally two, be separately mounted to through hole, angle steel two ends and and nut screw connection, realized the adjustment of height by rotary screw, and fixed by wing nut;
Handle, is welded on angle steel, angled with angle steel plane.
As the further improvement project of one, described angle steel is isometric with wind-tunnel width.
As the further improvement project of one, described nut is barrel nut, and length is equal to the width of angle steel one side.
As the further improvement project of one, described screw mandrel is provided with handwheel.
As the further improvement project of one, described handle is rod member, and rod member front end is welded on the midpoint of angle steel length.
As the further improvement project of one, described rod member end is provided with slip-proofing device.
A kind of wind-tunnel disclosed by the invention husky device of height-adjustable paving, has the advantages that
