Definitions

  • the present invention relates to the field of radio broadcasting equipment.
  • Such equipment is deployed in the field for remote transmissions, both in terms of telecommunications such as antennas for the GSM system (in English Global System for Mobile Communications) and PCS (Personal Communications Services), and more generally for radio relay stations, than other present or future technologies, which would require air links.
  • GSM Global System for Mobile Communications
  • PCS Personal Communications Services
  • Telescopic masts are known in particular, the essential merit of which is to allow a structure to gradually become lighter in height while retaining optimum resistance to the wind.
  • French patent FR2745423 describes an antenna support comprising two parallel fasteners articulated close to one another by one end at the base of a rigid support, and fixed to a vertical mast for form a deformable quadrilateral in the vertical plane to adjust the tilt of the antenna.
  • PCT patent WO9858420 relates to a cell site mast assembly, which is integrated with different antennas and components so that the assembly is easy to install on a cell site without the need for extensive wiring or the like.
  • the set also includes a light fiberglass housing, which surrounds the antenna without disturbing its operation.
  • the set presents a balancing system intended to raise or lower the housing in order to access the antenna.
  • PCT patent WO9966589 describes an antenna configuration intended to be used in particular with a cell phone system and in a rural environment.
  • This antenna device comprises a hollow steel support column covered with a hollow sheath made of plastic reinforced with glass fibers, for example.
  • the support column and the sheath are designed so as to have an external appearance simulating the bark of a tree, such as a Scots pine.
  • the column is bolted to a concrete base placed below ground level, and has a cover simulating the roots of the tree.
  • the sheath carries and encloses a omnidirectional antenna connected to a feed line passing through the column and through a pipe located inside the concrete base.
  • the equipment compartment of a cell phone system base station is connected to the antenna power line.
  • European patent EP106069 entitled "telescopic mast intended to support an antenna” provides for the pneumatic adjustment of the telescopic tubes, the advantage of which is the very rapid assembly on site, and the high compactness.
  • European patent EP57002 entitled “Telescopic antenna mast”, describes a device whose interest is only to highlight a telescopic system for lifting devices to high heights.
  • the value of the depointing should not exceed 1 °, even 20 ', in case of strong wind.
  • the present invention therefore aims to remedy the drawbacks mentioned.
  • the present invention thus relates to the production of a high-performance antenna support pylon, with reduced acquisition and operating costs, contributing to better environmental management and greater convenience and quality for users.
  • the invention relates, in its most general sense, to a pylon characterized in that it comprises at least one flexible rod having at its upper part a head in a plane substantially perpendicular to said rod, transverse spars and non-extensible means of connection , said transverse spars being articulated relative to said rod and forming with said connecting means deformable cells substantially retaining the parallelism of said spars.
  • the connecting means consist of at least two inextensible stays arranged on either side of the rod, fixed at one end at the base of the pylon, at the other end at the head, to form a deformable parallelogram keeping the head in a substantially constant plane.
  • the shrouds are integral with each of the spars, to form cells whose bases and tops are maintained in parallel planes.
  • the spars are connected to the rod by a recessed joint along the axis of the rod, free in at least one transverse direction and pivoting relative to at least one transverse axis.
  • the spars consist of substantially planar elements, and in that the connecting means comprise three guy lines.
  • the spars consist of substantially planar elements, and the connecting means by a plurality of flexible rods.
  • the head has a faired part which can be oriented along a vertical axis.
  • the head is mounted free to rotate and has aerodynamic drive means to create gyroscopic stabilization.
  • the rod is formed by a plurality of built-in elements.
  • the invention also relates to a radio broadcasting device comprising at least one pylon as defined above.
  • attachment points to the pylon could be limited to a lower level, instead of being distributed over the entire height.
  • the invention presents the possibility, compared to integral trellis systems, of placing the conductive cables inside the tubes sheltered from the weather.
  • a simple design of the central body is that in two or three superposed sections, bolted to each other by means of external flanges. Even more simply, a one-piece body can be designed when the transport conditions are not an unfavorable or unacceptable factor.
  • the invention is naturally conceivable in several variants, depending in particular on the materials, environmental conditions, aesthetics, etc..
  • a probably advantageous design allowed by the invention is that already mentioned consisting of a central body arranged in several frustoconical telescopic sections, of which a particularly simple and interesting arrangement is that consisting of a robust assembly by flanges or, for a given junction: flange attached to the outside of the lower part of the upper section, and flange attached to the inside of the lower tube in its upper part.
  • Another variant relates to a device having a lower lattice part, surmounted by a frustoconical upper part made of an envelope such as a tube.
  • the first consists of an articulated cone, a sort of planar ring arranged on concurrent inclined feet, and the second in a similar elastic ball joint in its training in certain joysticks or joysticks in English.
  • FIG. 6 represents a preferred articulation by cardan.
  • FIG. 7 illustrates an exemplary embodiment of a pylon comprising a bearing rod having a lower section (100) formed by a conical wire mesh extended by a plurality of section (101 to 104) nested one inside the other.
  • the rod supports at its upper end a head (105) articulated in pivoting and in transverse displacement.
  • Guy lines (110, 111) ensure the parallelism of the head (105) with the base of the device, and the maintenance of the head in a substantially constant plane, even when the rod bent under the action of the wind.
  • Spars (120 to 123) are articulated with respect to the rod and form with the shrouds deformable cells, retaining the parallelism of the spars.
  • the upper part has several platforms (130, 131) held parallel by the shrouds (110, 111) and articulated in pivoting and transverse displacement like the spars. These platforms allow the antennas (132) to be placed.
  • the rod also supports a housing (140) containing the electronic equipment. This avoids online losses caused by the cables connecting the antennas to electronic equipment usually placed at the base of the pylon.
  • This case has a double skin to improve heat exchange.
  • the assembly is done by first installing the conical lattice structure (100).
  • a winch is then installed at the upper end of this structure (100).
  • the upper section (103) equipped with the head is then hoisted, using the winch, until its base reaches a height allowing it to fit into the lower section (102). This operation is repeated by hoisting the newly introduced section with the winch to place the next section, and so on until the rod is raised.
  • the shrouds are fixed on the head at the start of the operation, and serve as guying in the provisional phase and are then subjected to a slight stress to balance the rod.
