Definitions

  • the present invention relates to so-called “wind” structures, the object of which is to control the transport and deposition of a pulverulent material (sand, snow, etc.).
  • this transport is the source of avalanches in the high mountains and the formation of snowdrifts on the communication routes of medium mountain regions.
  • DE-A-2817 015 shows such a snow guard which includes screens mounted to rotate around the horizontal axes. These screens direct the wind in a vertical plane but cannot be oriented relative to the directions of the wind in the horizontal plane.
  • a wind structure which, according to the invention, is placed automatically under the very action of the wind perpendicular to its direction, has the advantage of being able to be installed without prior measures.
  • the principle of the invention is to shift transversely - seen in a horizontal plane - the active part, or an auxiliary part, of the wind structure from its axis of rotation, which creates a parasitic torque which tends to move the work of an unstable equilibrium position of the vane type to bring it to a new stable equilibrium position which is perpendicular to the wind direction. It is in this position that the efficiency of a wind structure is maximum.
  • the self-orientating wind structures are divided into three groups which are barriers, windbreak panels and roofs-nozzles.
  • the barriers and panels are identical. Only the wooden decking differs, forming a square with 50% voids for the barriers and a small trapezoid side down with 10 to 30% voids for the panels.
  • the roof-nozzle retains the same metal framework as the two previous works, with the exception of the arm N which is telescopic and the decking which becomes rectangular, the short side being horizontal.
  • prefabrication becomes possible and they become competitive compared to fixed structures.
  • these structures are easily removable, which was not the case until now.
  • This advantage is less important with regard to the fight against avalanches in high mountains, but it becomes essential in the case of the fight against congers along the communication routes in medium mountains. In this case, farmers easily accept the implantation of works on their property only on condition that in summer everything is removed to allow the work which, most often, is haymaking. A removable cap will keep the foundation tube functional for the next winter season.
  • Wind-self-orientating structures can also, used in small numbers, advantageously replace a measurement campaign for the installation of a system of fixed structures. They then serve as “drift” indicators.
  • All of these structures consist of a support tube 1 made of high-strength steel at low temperature, founded either directly in the ground for a non-removable structure, or in a foundation tube K provided with fins L favoring the distribution of stresses in the ground.
  • a support tube 1 made of high-strength steel at low temperature, founded either directly in the ground for a non-removable structure, or in a foundation tube K provided with fins L favoring the distribution of stresses in the ground.
  • a removable plug M keeps the foundation tube functional between two winter seasons.
  • the support tube is capped by a rotation tube J closed at its upper end to prevent the penetration of the elements (water, frost or snow) in the simplified joint thus produced.
  • This rotation tube is positioned vertically to provide variable ground clearance by a screw-nut system F or a ring system (teflon or similar) - pin P and Q.
  • rotation of the tube J can be ensured by machined bearings or bearings.
  • a metal frame B also provided with articulation yokes E is fixed on the arms by means of axes or bolts H and of arms N allowing this frame to be inclined relative to the vertical.
  • These arms N can be mounted at the base or at the top of the metal frame.
  • Removable pins G and a fixed loop A allow transportation and installation by helicopter in the high mountains or by crane along the communication routes, of the whole assembly.
  • the roof-nozzle has a variable inclination with respect to the vertical which is obtained by means of telescopic arms O replacing the arms N of the other works.
