Definitions

  • the present invention relates to a terminal dam apparatus for use in collecting oil or the like floating on a water surface, comprising a barrier member having an opening for the through-flow of collected oil, and having end portions which, in use, e. g. are connected to the ends of respective dam lengths for the formation of a horseshoe_. configuration for the guiding of captured oil towards the apparatus.
  • the object of-the present invention is to provide a dam apparatus which in particular will contribute to increasing the efficiency of the oil defence in that it will provide an effective oil collection also under very adverse weather conditions and will function as a release valve when it is used together with conventional dams deployed in a horseshoe configuration.

  • the hose In the section of the hose extending between the opening 2 and the surface of the water, the hose has a decreasing cross-section and is e. g. conically tapering, in order to obtain a pressure on the oil flowing into the hose during operation, so that the oil can be transferred to the recovery means without the use of special pumping means.
  • Fig. 2 the oil flow is suggested with arrows A.
  • the gate means On the opposite side of the dam plate in relation to the hose 21 there is mounted a gate means with an associated operating means for movement of the gate between positions wherein the opening 2 is closed and open, respec ⁇ tively.

  • the sealing connection in closed position is achieved by a partial overlapping of the shutters.
  • each of the shutters are slidably mounted, by means of an upper holder 28 and a lower holder 29, on a horizontal, upper slide or guide rod 30 and a horizontal, lower slide or guide rod 31, respectively.
  • the holders may be made of acid-resisting light metal or plastic, and consist of a bearing member and a blade member projecting therefrom and being attached to the shutters by means of suitable bolts.
  • the guide rods 30 and 31 are attached to the dam plate 1 by means of end mountings 32.
  • stoppers 33 are provided , ⁇ .Pi on the guide rods and constitute abutments against the holders in the closing position of the shutters.

  • Each cylinder is at one end thereof attached to the dam plate 1 by means of a cylinder mounting 35, whereas the piston rod end of the cylinder is attached to the shutter in question by means of a rod mounting 36.
  • the hydraulic cylinders are operated by means of oil which is supplied by way of containers 37 for hydraulic oil, one container for each cylinder pair (schematically shown in Fig. 4) . Even if the cylinder/ piston units could be operated pneumatically, it is advan ⁇ tageous to use oil as working medium under the surface of the sea, in order to avoid condensation in the cylinder/ piston units.
  • control system for actuating the cylinders is, however, pneumatic, and for each cylinder it is thus provided a pneumatic/hydraulic control valve 38 which, by way of an associated air hose 39, communicates with a respective air bleed 40 in the buoyancy body 10 constituting the pressurized air source of the control system.
  • the buoyancy body 10 is provided with vacuum valves 41 opening automatically when the pressure in the buoyancy body decreases below a certain limit, so that the correct pressure is achieved again.
  • the control system is arranged to be actuated or operated by means of a radio remote control system of commercially available type, and for this purpose a re ⁇ garagever 42 (Fig. 5) is placed on the terminal dam apparatus, which receiver can receive control signals from a trans ⁇ mitter unit (not shown) by way of an antenna 43 projecting upwards from the buoyancy body 10 and being provided with a marker flag 44.
  • the receiver 42 is connected to a directional valve 45 which is in turn connected to the pneumatic/hydraulic control valves 38, so that the latter are positioned in the correct position for operation of the hydraulic cylinders for opening and closing of the ga means in dependence of the signals received by the recei 42.
  • the terminal dam apparatus is also provided with a green and a red lamp 46 and 47, respectively, which are actuated synchronously with the opening and closing of the gate means.
  • th 15 green lamp 46 is illuminated when the shutters 23, 24 are moved to the closed * position, and is kept illuminated as long as the opening 2 is closed, whereas the red lamp 47 is illuminated when the shutters are moved towards and ar in the open position.
  • the operat may also take place in dependence of the actual level of the collected oil.
  • one shutter 24 is provided with a plurality of sensors 48 arranged above ⁇ y r each other in the vertical overlapping area. Advantageo these sensors may be coupled to the directional valve 45 in order to open the shutters at a certain oil level.
  • the terminal dam apparatus On the dams coupled to the terminal dam apparatus there may be mounted tension sensors sensing the mechanic 0 stress and providing for opening of the shutters when a certain limit is exceeded, so that the terminal dam appar then automatically functions as a release valve for the dam system of which the terminal dam apparatus forms part.
  • a shield (not shown) to guide the oil int the through-flow opening. This may be necessary if the sea is rough. Further, it may be contemplated to be arranged an additional shutter which, by means of oil level sensors, can be arranged to shut the lower part of the through-flow opening 2 in dependence of the actual level of collected oil, so that it is secured that it is essential only oil which flows through the opening.
  • the terminal dam apparatus When using the terminal dam apparatus, this is deployed together with conventional dams as menioned above, so that a horseshoe configuration is formed with the termina dam disposed in the bottom of the horseshoe, and so that win waves and water currents will move the oil forwards to the terminal dam.
  • the dam system may be deployed and hauled by a pair of vessels, or it may also be stationary. Under calm weather conditions the oil can be collected in that the two vessels move towards the oil discharge.
  • the critical load on a dam system which is deployed in a horseshoe configuration will be reduced with 60 - 68% according to effected tests.
  • a simple operation is achieved as all manoeuvering can take place by means of a pair of levers in connection with the transmitter.
  • Such a remote control system can e. g. have a range of approximately 1000 meters.
  • the apparatus according to the invention has above been described in connection with the application at sea where it is intended to be connected to conventional dams for the formation of a e. g. horseshoe-shaped dam system.
  • the terminal dam apparatus can also be contemplated to be used in rivers, in order to capture and transfer toxic chemicals or other dangerous substances which have been dis- charaged and flow in the upper layers of the river water.
  • the apparatus is then installed with open gate and so that th contamination in the upper layers of the river water is guided towards the opening and flows therethrough.

L'appareil comprend un organe faisant barrière (1) ayant une ouverture (2) pour l'écoulement de l'huile ou autres matières récupérées, et ayant des portions extrêmes qui, en utilisation, sont reliées aux extrémités des longueurs respectives d'un barrage conventionnel pour la formation d'une configuration en fer à cheval permettant de guider l'huile encerclée vers l'appareil. L'organe faisant barrière est une structure en plaque rigide (1) qui, à l'aide de moyens de flottaison (12), flotte dans une position essentiellement verticale, et sur laquelle sont montés une porte d'écluse (23, 24) et un dispositif associé de fonctionnement (34) qui peut être actionné pour déplacer la porte d'écluse entre des positions permettant de fermer et d'ouvrir respectivement l'ouverture. Un tuyau flexible est relié à l'ouverture du côté regardant à l'opposé de la zone de récupération pour acheminer l'huile récupérée vers un bateau ou autre.
