Definitions

  • the devices Since the ship which launches these devices and which is usually also responsible for recovering them, is generally positioned at a considerable distance from the point at which the devices return to the surface, the devices are provided with means for marking their positions from a distance. Means of this kind include smoke-producing devices, flashing light generators, and radio buoys,
  • the antenna lead-through of the present invention is in tended to be applied.
  • the problem to be solved is that of detachably mounting an antenna on the tubular body of a radio buoy so that the assembly is watertight at very great depths of immersion and, at the same time, is sufficiently robust to resist the impacts which almost inevitably occur when the exploration devices are operated.
  • an antenna lead-through assembly for a Submersible radio buoy having a tubular body, the assembly comprising a plug fitted in the tubular body of the buoy, the plug having a tapered axial bore widening outwardly to receive the inner end part of the antenna which is of complementary shape and the plug having two generally cylindrical recesses formed one at the inner end and the other at the outer end thereof, a first toroidal seal interposed between the body and the plug.
  • a second toroidal seal fitted around the antenna in the outer cylindrical recess, a filling of hardenable synthetic resin in each of the cylindrical recesses, a sleeve surrounding the antenna outwardly of the plug, a cap fitted on the plug to lie around the sleeve, means for securing the plug and the cap to the tubular body, and an electric conductor for connecting the antenna to a signal generator of the buoy.
  • the cap and the plug can be mounted on the tubular body of the buoy by any suitable means, but these parts are preferably secured to the body of the buoy by screws made of plastics material such as nylon.
  • the toroidal seal fitted between the plug and the tubular body of the buoy is preferably seated in an annular groove formed in the surface of the plug.
  • the lateral surface of at least one of these recesses may contain an annular retaining groove.
  • the radio buoy partly shown in the drawing is designed to enable an emitter antenna 1 to radiate a highfrequency radio signal generated by means illustrated diagrammatically at 3 and connected to the antenna 1 by a conductor 2.
  • the electrical circuitry and its electric battery (not shown) are accommodated in tubular body 9 of the buoy.
  • the antenna 1 is preferably made of glass fibre and is provided with a central multi-strand core.
  • the water-tight fitting of the antenna 1 on the tubular body 9 is mainly achieved by means of a substantially axially-symmetrical plug 4 which is fitted in the body 9 by means hereinafter described, a toroidal seal 10 being interposed between the plug and the body.
  • the plug 4 has an axial bore in which is fitted one end of the antenna 1; this bore, which is tapered, widens outwardly in the direction away from signal generator 3 as does the lower end length of the antenna, and the bore matches the shape of the antenna to establish a satisfactory seal.
  • a cylindrical recess Sb is formed in the inner end of the plug 4 which is disposed within the buoy.
  • the end of the antenna 1 projects into this recess 5b as does the conductor 2, and a mouldable synthetic resin poured into the seat 5b contributes to the water-tightness of the assembly as a whole and enables the antenna to be held even more securely in position.
  • a generally cylindrical recess 5a is formed in the outer end of the plug 4, which is disposed near the exterior of the buoy.
  • a toroidal seal 6 surrounds the antenna l in this recess 5a into which a hardenable synthetic resin is likewise poured. The seal 6 then creates its own seat in the resin which, at the same time, ensures that the seal is bonded to the antenna.
  • an annular retaining groove formed in the lateral surface of the recess 5a imparts additional watertightness and promotes optimum adherence in the assembly as a whole.
  • a rubber sleeve 7 surrounded by a metal sleeve is passed over the free end of the antenna.
  • the rubber sleeve 7 is clamped onto the plug 4 by means of a cap 8 which, with the plug 4, is secured to the body 9 by means of three screws 11 which are preferably made of a plastics material such as nylon.
  • the function of the sleeve 7 is essentially that of reinforcing the base of the antenna 1 which is, in effect, weakened by being rigidly mounted in the plug 4.
  • the antenna lead-through thus obtained prevents the ingress of water at depths of immersion of the order of 6000 metres, which corresponds to a pressure of around 600 bars.
  • the assembly is sufficiently robust to resist the effects of violent impact.
  • An antenna lead-through assembly for a submersible radio buoy having a tubular body, the assembly comprising a plug fitted in the tubular body of the buoy, the plug having a tapered axial bore widening outwardly to receive the inner end part of the antenna tapered to a complementary shape and the plug having two generally cylindrical recesses formed one at the inner end and the other at the outer end thereof, a first toroidal seal interposed between the body and the plug, a second toroidal seal fitted around the antenna and residing in the outer cylindrical recess, a filling of hardenable synthetic resin in the inner cylindrical recess.
  • An antenna lead-through assembly in which at least one of said generally cylindrical recesses formed in the ends of the plug is provided with an annular retaining channel in its lateral surface.
