Definitions

  • the support for the working nozzle carries a reaction nozzle which discharges pressurized water in a direction counter to the direction of discharge from the working nozzle to thus facilitate underwater manipulation of the gun.
  • the support for the nozzles carries one or more inflatable and deflatable floats which determine the buoyancy of the gun.
  • a handle is used to adjust the floats as well as to adjust a steering flap at the rear end of the gun.
  • the present invention relates to apparatus for discharging directed streams of pressurized fluid below the surface of a body of water, and more particularly to improvements in socalled underwater guns which can be used to clean surfaces of submerged structures.
  • a drawback of presently known underwater guns which discharge jets of pressurized water is that they are complicated due to the provision of means for counteracting reaction forces which develop when the working nozzle discharges a jet of water against a submerged surface. Furthermore, the material which is removed by a jet of pressurized fluid floats in water adjacent to the area to be cleaned and obscures the vision of divers. Additional problems arise in connection with manipulation of known submersible water guns and also because the diver cannot stay in an optimum position with reference to the submerged body. It is customary to secure the diver in position by magnets or the like.
  • Another object of the invention is to provide a submersible water gun with novel and improved means for counteracting reaction forces which develop on discharge of pressurized fluid against a submerged surface.
  • a further object of the invention is to provide the submersible gun with novel means for preventing turbulence at the working station.
  • An additional object of the invention is to provide a submersible gun which can be held at a desired distance from the surface to be cleaned and wherein the jet of pressurized fluid is not braked at all or is subjected to negligible retarding forces in the space between the orifices of the working nozzle and the surface to be cleaned.
  • Still another object of the invention is to provide the gun with novel means for manipulating it under water and with novel means for regulating its buoyancy.
  • the invention is embodied in an apparatus for discharging directed streams or jets of pressurized fluid (preferably water) to clean surfaces of bodies which are submerged in water.
  • the apparatus comprises a submersible support, first nozzle means installed in or on the support and having at least one orifice arranged to discharge pressurized fluid in a first direction whereby the thus discharged fluid can be directed against a submerged body, reaction nozzle means installed in or on the support and having at least one orifice arranged to discharge pressurized fluid in a second direction counter to the first direction so that the reaction nozzle means produces forces which counteract forces developing on discharge of pressurized fluid from the first nozzle means, and means for supplying pressurized fluid to the nozzle means.
  • the apparatus preferably further comprised one or more floats, for example,
  • inflatable and deflatable tanks of rubber or the like which control the buoyancy of apparatus under water.
  • FIG. 1 is a longitudinal vertical sectional view of a cleaning gun which embodies one form of our invention
  • FIG. 2 is a fragmentary top plan view as seen in the direction of arrow II in FIG. 1;
  • FIG. 3 is a longitudinal vertical sectional view of a second cleaning gun
  • FIG. 4 is a transverse vertical section as seen in the direction of arrows from the line lV-IV of FIG. 3;
  • FIG. 5 is a fragmentary longitudinal vertical sectional view of a third cleaning gun.
  • FIG. I illustrates a cleaning gun which comprises a tubular support or holder 7 for a first nozzle or working nozzle I having a centrally located orifice which discharges a jet of highly pressurized liquid fluid in a direction to the left so that such fluid can be directed against a submerged body, not shown.
  • a second nozzle or reaction nozzle 2 has an orifice which discharges pressurized fluid in a direction counter to the direction of fluid discharge from the orifice of the nozzle 1.
  • the nozzle 2 discharges into an injector 3 and its reaction is greater than that of the working nozzle 1.
  • the injector 3 discharges fluid into a mixing nozzle 4.
  • the injector 3 is preferably of annular shape to insure that the apparatus may employ a relatively short mixing nozzle 4.
  • the orifice of the working nozzle 1 is preferably designed to discharge a flat stream of pressurized fluid (between 30 and This nozzle I is surrounded by a first or inner funnel 5 with two flat sides which is sealingly secured to the left-hand end of the support 7.
  • the funnel 5 has one or more inlet openings 8 connected to a flexible hose 9 the upper end of which is secured to a snorkel 10.
  • a buoy 10a or the like holds the inlet of the snorkel 10 above the water surface so that the interior of the funnel 5 (which is under vacuum when the working nozzle I discharges pressurized fluid by way of the I discharge opening at the left-hand end of the funnel) can draw atmospheric air by way of the snorkel I0, hose 9 and opening or openings 8.
  • a second or outer funnel 6 surrounds with clearance the inner funnel 5 and is connected with the injector 3 by way of a third funnel or sleeve 19.
  • the mixing nozzle 4 discharges pressurized fluid into the mixing nozzle 4, such fluid draws water into the left-hand end of the outer funnel 6 whereby the thus drawn water entrains dirt and other matter which might obscure the vision of the diver at the point where the jet issuing from the orifice of the working nozzle 1 performs its cleaning action.
  • the mixing nozzle 4 has an extension or diffuser 20 which accommodates an adjustable steering flap l2 tumable with reference to a horizontal pivot structure 11 (see also FIG. 2).
  • the control means for adjusting the inclination of the flap 12 comprises a linkage 14 which is outwardly adjacent to the parts 19, 20 and a manually operated actuating member or handle 13 which can swivel about a pivot member 13a on the funnel 19 to thereby move the linkage 14.
  • the reaction of the nozzle 2 exceeds the reaction of nozzle 1 by one or more kilopounds; therefore, the diver who manipulates the handle 13 can readily control the gun under water with a high degree of precision.
  • the support 7 or another part which is mounted on the support carries one or more floats 17 which contribute to and regulate the buoyancy of the gun.
  • the float 17 includes a deformable tank, e.g., an inflatable balloon of rubber or other suitable elastomeric material.
  • the handle 13 has a sleevelike handgrip portion 15 which can be manipulated by hand to pivot at 13a and to thereby adjust the inclination of the steering flap 12.
  • the sleeve 15 is preferably rotatable on the inner part of the handle 13 to thereby regulate an adjustable valve 16 which can permit escape of air or other suitable gas from the interior of the tank 17 at a desired rate.
  • the valve 16 is preferably a three-way valve which can permit evacuation of fluid from the tank 17 and can also connect the tank with a source of compressed gaseous fluid, not shown.
  • the device which supplies pressurized liquid fluid (for example, water) to the nozzles 1 and 2 is shown at 30.
  • This device has a trigger 31 which can be depressed to initiate admission of pressurized fluid.
  • the diver By regulating the position of the valve 16, the diver can change the buoyancy of the gun.
  • the support 7 (or a part which is connected thereto) further carries one of more underwater lamps 32 which illuminate the area to be cleaned by jets issuing from the orifice of the working nozzle 1.
  • the outer funnel 6 preferably carries one or more suitable distancing members 18 which enable the diver to hold the orifice of the working nozzle 1 at a desired distance from the surface to be cleaned.
  • Such distancing members 18 may constitute wheels or rollers which can roll along the surface of a submerged body. Alternatively, the members 18 may constitute sleds or like parts which can be shifted with little friction.
  • the apparatus preferably comprises two distancing members 18 each of which is adjacent to one flat side of the outer funnel 6.
  • the numeral 33 denotes an auxiliary handle which can be grasped by the other hand of the diver to facilitate manipulation under water.
  • FIGS. 3 and 4 illustrate a second submersible cleaning gun which is similar to the gun of FIGS. 1 and 2. Those parts which are clearly analogous are denoted by numerals similar to those employed in FIGS. 1 and 2 but each followedby a prime.
  • the second nozzle 2' is remote from the working nozzle 1' and is centered in the injector 3 by radially adjustable screws 34 (see particularly FIG. 4). The extension is omitted and the linkage 14 is employed to shift the mixing nozzle 4' axially with reference to the nozzle 2'.
  • the injector is omitted so that fluid issuing from the orifice of the nozzle 2" enters directly into the mixing nozzle 4".
  • This mixing nozzle 4 is movable axially with reference to the nozzle 2" in the same way as shown in FIG. 3.
