Definitions

  • the present invention concerns a device for the automatic adjusting, according to the pressure, of the length of the connection rope between a buoy and a skin-diver.
  • the present invention takes its origin from the need to take the exact position of skin-divers with repect to the floating indicator buoy, so as to reduce the dangers deriving from incidents caused by arriving floating means.
  • connection rope between said buoy and the skin-diver has always the same length, thus representing only the limit of the reciprocal distance.
  • the aim set forth is reached by means of the device according to the present invention, comprising a winding and unwinding means for the connection rope between a floating buoy and an immersed skin-diver, so as to determine the automatic adjusting of its length following to the indications supplied by a pressure measuring sensor, provided on said skin-diver or on his spear gun or in any other housing.
  • the device for unwinding the rope may be provided, according to the present invention, in correspondence with the buoy, and in that case the connection with the pressure sensor is realized with an acoustic emitter, of the sonar kind, or by means of an electrical connection obtained inside said rope, or said device - in a possible variant - may be carried by the skin-diver, may be applied to the spear gun or in any other place.
  • Figure 1 shows a scheme of a device for the automatic adjusting, according to the hydrostatic pressure, of the length of the connection rope between a buoy and a skin-diver.
  • Figure 2 shows a block scheme of the functioning of the device according to the present invention.
  • Figures 3 and 4 show some possible variants of the device according to the present invention.
  • the figures show a device for the automatic adjusting, according to the pressure, of the length of the connection rope between a buoy and a skin-diver, of the kind that can be inserted during the realization into floating buoys B of new kind, or also applied to the lower ring of already existing buoys B, comprising: a mechanism 1 for winding and unwnding a rope C, that can supply the length of the rope according to the values of the hydrostatic pressure taken by a sensor 2 inserted inside a watch or carried by the immersed skin- diver;
  • an acoustic receiver 5 for taking, through the liquid means, the waves coming from the emitter 4, connected to the skin-diver;
  • a pressure sensor 6 for transforming the measure of the depth reached by the skin-diver into hydrostatic pressure values.
  • the device according to the present invention comprises, beyond the already mentioned details, an electric battery BA, a counter 9 of the recolutions of the electric motor 3 and a circuit 10 for the comparation between the depth and the revolution number so that the values of the hydrostatic pressure taken by the sensor 6 are translated, in real time, into the winding or unwinding of predetermined lengths of the rope C.
  • said pressure sensor 6, through the transducer 7, sends an electric impulse which, passing through the cable 8, reaches the motor 3 connected to the buoy B, thus determining the winding or unwinding of the rope C, according to the taken pressure.

Abstract

L'invention concerne un dispositif d'ajustement automatique, en fonction de la pression, de la longueur du câble de raccordement entre une bouée et un plongeur. Ce dispositif comprend un élément (1) permettant d'enrouler et de dévider un câble (c) destiné à relier une bouée à un plongeur en immersion et de déterminer l'ajustement automatique de la longueur dudit câble en fonction des indications fournies par un détecteur (6) qui mesure la pression et qui est placé directement sur le plongeur ou sur son fusil lance-harpon ou sur tout autre boîtier. L'information sur la profondeur atteinte est transmise audit élément (1) à l'aide d'un émetteur (4) d'ondes acoustiques avec un récepteur (5) relatif ou, dans une autre version, à l'aide d'impulsions électriques qui passent par le câble de raccordement entre un plongeur et une bouée (B).
