Abstract
A self-orientating barrier fence for use in controlling snow or sand drifts or other airborne particles which is rotatably mounted on a support in such a manner as to automatically direct itself into a position perpendicular to wind. The barrier fence may be positioned without regard to measurements of wind direction and may be removed when it is not needed.
Claims12
A barrier fence for use in controlling airborne particles, said barrier fence comprising a frame and a plurality of boards connected to said frame, said boards being spaced from one another, and means for automatically positioning said fence continuously in any position about 360.degree. and which is perpendicular to the direction of a wind current, said means for automatically positioning said fence comprising a support adapted to be connected to a base structure, a rotation tube mounted on said support, said rotation tube having a top end and a bottom end, wherein said frame is connected to said rotation tube, said rotation tube further comprising tilting means for altering the angle of said frame in accordance with the slope of terrain on which said barrier fence is placed.
A barrier fence for use in controlling airborne particles, and for detecting the direction and extent of a drift deposit of a pulverulant material, said deposit occurring as a result of wind, said fence comprising means for automatically positioning said fence continuously in a position perpendicular to the direction of a wind current at any time, said barrier fence comprising:
- (a) a foundation tube, sai foundation tube having a top end and a bottom end, said top end being wider in diameter than said bottom end;
- (b) a support, said support being removably positioned within said foundation tube,
- (c) a rotation tube, said rotation tube being rotatably mounted on said support;
- (d) a metallic frame, said frame being attached to said rotation tube by tilting means allowing said frame to be inclined at varying angles with respect to the slope of the terrain;
- (e) means for detachably securing said rotation tube to said support said means comprising at least one pin, said pin being removably connected to said rotation tube;
- and
- (f) a plurality of slats spaced from each other and located substantially horizontally.
