  • a housing or casing having a pressure balancing April 3, Japan mechanism such as a diaphragm or bellows is with a suitable fluid, such as oil, to both prevent ero- [52] US. Cl. ..95/ll w sion and to permit the casing structure to be immune [51] Ililt. Ci. nG03.) 17/08 to h ff of ambient pressure
  • the casing is F Qld of Search designed specifically to protect such devices as l References Cited cameras used underwater.
  • the present invention relates to a casing structure used for enclosing underwater devices such as an underwater camera and the like.
  • the conventional casings for enclosing underwater mechanisms such as underwater cameras, submarine robots, oceanographical instruments, and the like, have, by necessity, been provided with both water-proof means so that the mechanism will not be damaged by sea water and a pressure resistant structure for protecting the mechanism in the casing from the relatively high pressure exerted by the water as a device is progressively used further beneath the surface of the sea.
  • the conventional casing structure has been both complicated construction and costly to manufacture.
  • the present invention solves the problems that existed in the prior art in a simple and efficient manner, by providing an underwater casing which does not require elaborate pressure resistance meansor waterproofing means. This, is accomplished by combining in a simple structure apparatus, which jointly permits equalization of the pressure, while preventing the eroding effects of sea water. This is accomplished by filling the underwater casing with a fluid that will have the same pressure as the surrounding sea water and permitting the pressure within the casing structure to be controlled to be always equal to that of the water pressure outside the casing by providing pressure balancing means on the casing wall. This removes the necessity for having a sturdy and bulky structure as generally is required in the prior art. By filling the underwater casing with a fluid, such, as oil, the mechanism contained within the underwater casing is prevented from being damaged by the water.
  • a fluid such, as oil
  • the pressure balancing means utilized in the present invention can be for instance, a flexible wall portion provided on the wall of the, casing structure.
  • Thisflexible wall portion will be fluid, tight and prevent the leakage of the enclosed fluid while permitting the equalization of the pressure in the fluid to that of the water pressure outside the casing.
  • Fluids for filling the underwater casing can be, for example, colloid of gel orsol, such a gelatin, as well as oil, and other similar materials. possessing the same characteristics.
  • FIG. 1 is a schematic sectional view of one embodiment of the underwater casing in accordance with the present invention.
  • FIG. 2 is. a schematic sectional view of another embodiment of the underwater casing in accordance with, the presentinvention.
  • a closed underwater container 1 is provided with a diaphragm 2 as a part of its top wall.
  • the closed container 1 is filled with a fluid, such as liquid paraffin 3.
  • the underwater casing structure can maintain its fluid tight relationship with the liquid paraflin 3 without resorting to excessive bulky structure due to the ability of the casing to balance the pressure on the inside of the casing with the pressure on the outside of the casing by virtue of the diaphragm 2.
  • an underwater camera 7 is connected through a driving shaft 6 with a motor 4.
  • the motor 4 is driven by an electric cell 5.
  • the electric cell 5', its electrical connections and the motor 4 along with a portion of the shaft 6, is enclosed within the underwater casing.
  • the underwater camera 7 has its own fluid tight structure, but
  • the underwater camera 7 to be positioned within the underwater casing 1.
  • the liquid paraffin 3 protects those parts of the underwater camera system that are most susceptible to damage by the sea water.
  • the clearance or bore between the underwater casing l and the shaft 6 is sealed to prevent the introduction of sea water into the interior of the underwater casing 1.
  • the seal employed can be of a relatively simple structure, since there will be no marked difference in pressure between the outside and the inside of the underwater casing 1.
  • the diaphragm 2 maintains the pressure within the underwater casing 1 equal to the water pressure outside the underwater casing 1.
  • the pressure resistant means and the water-proofing means utilized in a conventional underwater casing is eliminated. It is clear that other accessories of a camera, or similar devices, could be enclosed within the underwater casing, such as a flashlight device or a strobe.
  • the underwater casing l is provided with a bellows 20 instead of the diaphragm 2 employed in the first embodiment.
  • the function of the bellows is the same as that of the diaphragm 2 utilized in the embodiment of FIG. 1.
  • the reference numeral 40 of FIG. 2 is indicative of any underwater instrument that needs to be protected when submerged.
  • Various fluids can be employed to fill the underwater casing 1, such as, diphenyl chloride, kerosene, light oil, silicone oil, machine oil, heavy oil, and other similar fluids having the same or similar properties.
  • the fluid utilized within the underwater casing 1 need not be transparent and accordingly, it is possible to use a gel like gelatin to fill the underwater casing 1.
  • the present invention as described above, provides a pressure balancing means on the wall of the underwater casing structure, which permits the pressure within the underwater casing to be maintained at a pressureequal to that of the water pressure outside of the underwater casing. Consequently, the pressure resistant means generally employed in a conventional underwater casing, and further, the water-proofing means required in an underwater instrument casing, can be eliminated.
  • the present casing for underwater instruments, such as cameras, can be made extremely simple in construction and accordingly, in an economical manner.
  • pressure balancing means regulating the interior pressure within the housing member in accordance with the ambient pressure
  • a non-corrosive fluid filling the housing member and covering the electrical power source and motor;
