[Prior art]

 In the past, devices have been developed that allow divers to get on board and move underwater while working.However, as in the present invention, air is sent from the water surface with a hose, and air flows only when the diver breathes. There is no integrated multipurpose device that integrates a diving device based on the so-called Hooker diving system that supplies water and a device for movement.

[0002] Conventionally, most of the devices that travel underwater are like underwater scooters, which are mainly powered by batteries and are electrically driven. It was completely different. And the battery-powered scooter could only run for a short time before the battery ran out. Also, underwater vehicles that send air from above the water surface did not use underwater vehicles. This is because the hose becomes a resistance to running and the battery is quickly consumed. When power was sent by cable, the power did not attenuate over time, but the voltage attenuated due to the resistance due to the length of the cable.

[0003] Also, when considering a tool to be carried during diving, the amount of equipment that a single diver can wear on his / her body or with his / her hand is limited. For example, when conducting various surveys underwater, it is not possible to carry a large number of things at the same time, such as a video camera, a still camera, a scale for collecting (such as a metal frame), bottles and bags for collecting the objects, and so on. There was a need for a suitable underwater vehicle that could transport everything at the same time.

[0004] Diving from a depth of 60 meters to 100 meters is called a medium depth diving. This medium depth diving involves the use of helium and oxygen or a special respiratory gas containing a mixture of helium, oxygen, and nitrogen. Use it to descend on a stage (table) suspended from the water surface by a winch. Since the heavy stage was suspended by a winch, and the failure of the winch affected the lives of the divers, the winch needed to be large and the mother ship had to be large. Under high wave conditions, diving work was not possible because the ship shakes and the stage shakes. Also, since the stage cannot sail on its own, if the dive point shifts, the entire work may be wasted. The present invention does not require a winch for suspension because the frame is lightweight and can move up and down by itself, so a large ship is not required. By adjusting the buoyancy, it is possible to maintain neutral buoyancy that neither lifts nor sinks, so it is not affected by the wave height of the water surface. In addition, because it can sail on its own, it can move in deep water without losing physical strength.

[0005] Further, as a problem that is urgently required to be solved, there is a problem of securing safety against assault of aquatic organisms. In other words, since the 1990s, the number of shark attacks has increased and the number of human-related problems has increased rapidly. In the past, (1), a diving fisherman died in March 1992 off the coast of Matsuyama, Ehime Prefecture, at a depth of 22 meters, where a submerged fisherman diving in a helmet-type diving helmet-type diving fish was used. (2) In June 1992, a small fishing boat for one person was bitten by a giant shark in Iyo-Nada, Ehime Prefecture, leaving two great white shark teeth on the side of the boat. (3) A case in which a man who went fishing in Amami Oshima in August 1992 was lost, and as a result of a search, shaved teeth were found on the seabed and bitten clothing was found. (4) In March 1993, a tiger larva diving diver encountered a large shark in the Iyo Nada, but did not suffer any damage because he was carrying his own armor. (5) A woman swimming in Amami Oshima in August 1994 was bitten by a shark on her right leg. (6) In April 1995, a fisherman diving scuba divers at the depth of 27 meters in the Atsumi Peninsula was killed, but it is presumed to be due to a great white shark. (7) In July 1996, a captain of a patrol boat was killed while examining the bottom of a coral breeding survey conducted by Hirayoshi Miyakojima in an environmental assessment survey. (8) In July 1997, an underwater octopus fishing fisherman died of a bite bleed or shock at a location only 400 meters away from the previous accident at Miyarajima Taira. This also seems to be a great white shark or tiger shark.

[Problems to be solved by the invention]

 The diving equipment of the present invention is primarily intended for diving while avoiding shark damage. In other words, one way to ensure that large sharks are not attacked is to enter a shark avoiding cage. However, she cannot work in a cage. If you leave the cage too far away, you won't be able to return in case of emergency. If the shark avoiding cage itself can travel and move, it will be possible to work while avoiding shark attacks. The present invention is to provide an excellent diving operation device that solves these problems. In other words, by entering this device (frame), it is possible not only to enable self-propelled operation for a long time while avoiding assaults such as sharks, but also to transport many necessary equipment at the same time. It also provides a dive work device suitable for mid-dive diving.

[0007]

[Means for Solving the Problems]

 The present invention will be described with reference to the drawings. "The buoyancy of the frame 1 is attached to a frame 1 made of a light member such as an aluminum pipe or plastic having a doorway 2 for a person by welding or other method. A buoyancy tank 3 is provided above the frame 1 so that the frame 1 can be freely floated and lowered, and a propulsion device 4 for allowing the frame 1 to run freely is attached to the front or rear surface of the frame 1 in the traveling direction. Compressed air sent by a compressor from a top via a hose 5 is injected into the buoyancy tank 3 to float, the air in the buoyancy tank 3 is discharged by a discharge valve (not shown), and sunk, and The buoyancy was adjusted, and the frame 1 was propelled by a hydraulic drive from a hydraulic pump placed on the surface of the water, and a propeller or other propulsion device 4 was turned to run underwater. Maneuver Possible and the diving working device. Is intended to provide. "

FIG.

In the present invention, the driving of the propulsion device for moving the device underwater is performed using hydraulic pressure or hydraulic pressure. Therefore, the propulsion force does not attenuate even when time elapses unlike battery driving, and The length of the hose does not attenuate the power source.

[0009]

[Embodiment of the invention]

 Frames made of lightweight plastic and aluminum pipes are designed to allow divers to ride. The frame is preferably surrounded by a 20 cm to 30 cm grid to avoid large shark attacks. At least the top or side part shall be accessible to divers. It is convenient to get in from the top of the frame with the frame floating above the water surface, and underwater from the entrance provided on the side surface.

In the diving operation, when the exhaust valve of the buoyancy tank is opened to evacuate the air, water enters the buoyancy tank, the buoyancy is lost, and the dive starts. Air is supplied to the device (buoyancy tank) through a hose from an air compressor placed on board or on land, and the air is supplied to the buoyancy tank for breathing by divers. It is used for both lifting equipment.

The diver is supplied through a demand regulator attached to the tip of a breathing hose that branches off the hose (ie, only when the diver inhales, vents as much air as the diver requires). Breathe the air. This air supply system is the same as what is called a Hooker submersible.

By opening a cock (not shown) attached to the end of the hose, air is also injected into the buoyancy tank. When air is injected into the buoyancy tank, the buoyancy increases, the descent is stopped, and the buoyancy tank begins to float. By properly adjusting the exhaust and injection, the device can be neutrally buoyant without lifting or sinking.

[0013] The hose 5 basically includes one hose for sending air, two hydraulic hoses for supplying power to rotate the propeller of the propulsion unit (the hydraulic pressure is a reciprocating hose), and warms the body of the diver. A configuration in which a total of four hoses, one for sending hot water, are bundled.

The propeller (propeller) 4 is mounted on the front or rear surface in the traveling direction of the frame, and moves forward and backward or stops by opening and closing a hydraulic valve. If the hydraulic valve is opened widely, the rotation increases and a large propulsion force is obtained to increase the speed, and if the hydraulic valve is throttled, the vehicle can move forward slowly. Hydraulic pressure is optimal for the propulsion of the device, as it does not weaken even when sent through long hoses. The propulsion device can change the direction of propulsion to upward, downward, rightward, leftward, etc. by maneuver, so that the device can be easily controlled by divers.

[0015] With regard to ensuring safety, even if the supply of air by the hose is interrupted, it is possible to easily return to the surface of the water by using the scuba for emergency levitation.

Depending on the contents of the work, it is possible to devise so as to be able to work inside the apparatus, but depending on the contents of the work, it is necessary to go out of the frame. Divers can go outside and work by setting the sides so that the entire frame can be flipped up in a hinged state. If the hose that sends air to the diver is of a suitable length (for example, 5 to 10 meters), it is possible to work out of the equipment within this radius. When moving, you can control yourself in the frame, and if you are outside the frame, if a shark appears, return to the frame, close the side frame, run the device, and return to the ship. In case of emergency, you can also return to the ship by dragging the hose on the ship. The ship and the diver can also be contacted via a wired telephone. The communication line of the wired telephone can be bundled together with the hose.

[0017] It is preferable that the total weight be kept to 50 kg or less so that the work can be performed from a small boat that can be driven by an outboard motor and can be lowered and lifted by one person. . However, it can be made slightly larger so that multiple people can ride it.

[0018]

[Effects of the Invention] The present invention has an excellent utility not only as a shark avoiding cage, but also as a diving equipment or underwater vehicle. As an example, in the work of loading and flattening stones in harbor construction work, the stones can be lifted and moved by the buoyancy of the buoyancy tank, and physical strength can be reduced.

When conducting various surveys underwater, a video camera, a still camera, a scale (eg, a metal frame) for collection, and a bottle or a bag for collecting collected items may be carried at a time with all of them secured at hand. I can do it. It is desirable that diving and diving between the water surface and the seabed be as small as possible. The present invention, which can carry everything at once, can be very effective.

[0020] Furthermore, since the diver can run without using the power of his / her own feet, the diver can use and work with a physically handicapped person having a movement disorder. In addition, since it is an interesting vehicle for fun, ordinary divers can enjoy diving with divers who have handicap.

[0021] When diving at a depth of more than 70 meters, the elevator stage can travel on its own and can float and sink by itself without using a large crane. A long decompression stop, which can take a long time, can be spent lying on the device, making it easy. If you keep the hose of hot water together with the air supply hose and hydraulic hose as a method of keeping the heat during diving, you can dive without worrying about the cold.
