DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 9 As shown, in an embodiment of the present invention, a diving cage rapid floating device comprises a cage body 1, a protective door 2 is hingedly connected to one side of the cage body 1, a lifting plate 3 is fixedly installed on the top of the cage body 1, and a rapid floating assembly is arranged on the top of the cage body 1;

[0033] Among them, the rapid floating assembly includes a compressed gas cylinder 5 arranged at the top of the cage body 1, and two compressed gas cylinders 5 are symmetrically arranged. One end of the two compressed gas cylinders 5 is fixedly connected to the first connecting pipe 6, and the inside of the two first connecting pipes 6 is provided with a control assembly, and the two sides of the two first connecting pipes 6 are fixedly connected to the second connecting pipe 13, and each second connecting pipe 13 is installed with a first buoy 4 at one end away from the first connecting pipe 6, and each first buoy 4 is fixedly installed at the top of the cage body 1, and the inside of the cage body 1 is provided with an auxiliary floating assembly;

[0034] The control assembly includes a control board 7 arranged inside the first connecting tube 6, the bottom end of the control board 7 is fixedly connected to a connecting rod 8, a limit plate 9 is fixedly installed on the outer wall of the connecting rod 8, a first spring 10 is arranged at the bottom end of the limit plate 9, the bottom end of the connecting rod 8 is fixedly connected to a pull rope 11, and the bottom end of the pull rope 11 is fixedly connected to a pull ring 12.

[0035] By cooperating with the rapid buoyancy component and the control component, when it is necessary to make the diving cage float quickly, the diver can pull the pull ring 12 downward, and drive the connecting rod 8 to move downward through the pull rope 11. The movement of the connecting rod 8 drives the movement of the control panel 7, so that the control panel 7 moves downward to open the second connecting pipe 13, and the first connecting pipe 6 is connected to the second connecting pipe 13. The gas inside the compressed gas cylinder 5 is transmitted to the first buoy 4 through the first connecting pipe 6 and the second connecting pipe 13, and finally the diving cage is quickly floated through the first buoy 4, avoiding the current diving cage device The slow rising speed of the traction mechanism cannot be responded quickly, increases the risk of the operation, and leads to poor equipment safety. The cage body 1 is quickly risen through the first buoy 4, which improves the safety of the diving operation.

[0036] like Figures 1 to 9 As shown, the auxiliary floating assembly includes a second float 15 arranged inside the cage body 1, and the second float 15 is installed inside the cage body 1 through a connecting assembly. Connecting blocks 16 are fixedly installed on both sides of the second float 15, and one side of the connecting block 16 is connected to a third connecting pipe 14, and the end of the third connecting pipe 14 away from the connecting block 16 is installed on the side wall of the first float 4.

[0037] By setting up the auxiliary buoyancy component, when the first buoy 4 is filled with gas, a part of the gas in the first buoy 4 is transmitted into the second buoy 15 through the third connecting pipe 14, and the interior of the second buoy 15 is also filled with gas, thereby assisting the submersible cage to float quickly, further improving the floating efficiency of the submersible cage.

[0038] like Figures 1 to 9 As shown, two second floating bodies 15 are symmetrically arranged.

[0039] When the diving cage moves up, the second float 15 is located on the water surface, so that the diving cage remains in a vertical state on the water surface, preventing the diving cage from tipping over after moving up to the water surface. Divers in the cage body 1 find it difficult to stand, which not only affects stability and comfort, but also affects the divers' ability to leave the cage body 1, thereby improving the stability of the diving cage.

[0040] like Figures 1 to 9 As shown, the connecting assembly includes a first rotating shaft 20 embedded in the inner wall of the cage body 1, and two first rotating shafts 20 are symmetrically arranged. The top ends of the two first rotating shafts 20 are fixedly connected to the limit blocks 19, and the outer walls of the two limit blocks 19 are sleeved with mounting belts 18. The two mounting belts 18 are both arranged on the outer wall of the second float 15, and the bottom ends of the two mounting belts 18 are fixedly connected to the cage body 1.

[0041] A connecting groove is provided inside the mounting belt 18, and the mounting belt 18 is slidably connected to the limit block 19;

[0042] When the second floating body 15 is installed in the cage body 1, the limit blocks 19 and the connecting grooves in the installation belt 18 are arranged alternately;

[0043] The second floating body 15 is installed in the cage body 1 by sleeve-connecting the installation belt 18 to the bottom end of the limit block 19 .

[0044] like Figures 1 to 9 As shown, the bottom ends of the two first rotating shafts 20 are fixedly connected with the first gears 21 , one side of the two first gears 21 is meshedly connected with the second rack plates 22 , and the two second rack plates 22 are fixedly connected.

[0045] When the second floating body 15 needs to be removed, the limiting block 19 is first rotated to make the limiting block 19 overlap with the connecting groove in the installation belt 18, and then the installation belt 18 is removed, and finally the second floating body 15 is removed.

[0046] like Figures 1 to 9 As shown, the two second rack plates 22 are symmetrically arranged.

[0047] When the limit block 19 is rotated, the rotation of the limit block 19 drives the rotation of the first rotating shaft 20, the rotation of the first rotating shaft 20 drives the rotation of the first gear 21, and the rotation of the first gear 21 drives the movement of the second rack plate 22, so that the two limit blocks 19 rotate at the same time, improving the disassembly efficiency.

[0048] like Figures 1 to 9 As shown, a binding belt 17 is fixedly mounted on the side wall of the connecting block 16 .

[0049] After the second buoy 15 is removed, it can be tied with the binding belt 17 and tied to the diver for emergency use to prevent the diving cage's lifting equipment from being damaged and the diving cage from being unable to rise normally. The second buoy 15 is tied to the diver to assist the diver in rising and leaving safely, thereby improving the safety of the device.

[0050] like Figures 1 to 9 As shown, a second ball valve 28 is rotatably installed inside the cage body 1, a third rotating shaft 29 is fixedly connected to one side of the second ball valve 28, a third gear 30 is fixedly installed at one end of the third rotating shaft 29, and a fourth rack plate 31 is meshedly connected to the bottom end of the third gear 30.

[0051] like Figures 1 to 9 As shown, one end of the fourth rack plate 31 is fixedly connected to a slider 32 , and one side of the slider 32 is provided with a second spring 33 .

[0052] When the second floating body 15 is installed in the cage body 1, the connecting block 16 is in contact with the side wall of the cage body 1, and the connecting shaft 26 is located at the end of the fourth rack plate 31 to limit its position;

[0053] When the second float 15 is taken out, the connecting shaft 26 is separated from the fourth rack plate 31, and the elastic potential energy released by the second spring 33 drives the slider 32 to move. The movement of the slider 32 drives the movement of the fourth rack plate 31. The movement of the fourth rack plate 31 drives the rotation of the third gear 30. The rotation of the third gear 30 drives the rotation of the third rotating shaft 29. The rotation of the third rotating shaft 29 drives the rotation of the second ball valve 28, blocking the gas from continuing to be discharged, preventing the gas in the first float 4 from being exhausted through the third connecting pipe 14 after the second float 15 is removed, thereby improving the stability of the device.

[0054] like Figures 1 to 9 As shown, a connecting shaft 26 is fixedly installed on one side of the connecting block 16, and a first ball valve 23 is rotatably installed inside the connecting shaft 26. A second rotating shaft 24 is fixedly installed on one side of the first ball valve 23, and a second gear 25 is fixedly installed on one end of the second rotating shaft 24. The bottom end of the second gear 25 is meshingly connected with a third rack plate 27, and the third rack plate 27 is fixedly installed inside the cage body 1.

[0055] When the second float 15 is taken out, the connecting shaft 26 moves to the side away from the cage body 1, driving the second gear 25 to move and engage with the third rack plate 27 to rotate. The rotation of the second gear 25 drives the rotation of the second rotating shaft 24. The rotation of the second rotating shaft 24 drives the rotation of the first ball valve 23, so that the inside of the connecting block 16 is blocked to prevent gas leakage in the second float 15, making it easy for the second float 15 to be removed and used separately.

[0056] Working principle and usage process:

[0057] When the diving cage needs to be quickly floated, the diver first pulls the pull ring 12 downwards, and the movement of the pull ring 12 drives the pull rope 11 to pull the connecting rod 8 downwards, and the movement of the connecting rod 8 drives the movement of the control panel 7, so that the control panel 7 moves downwards to open the second connecting pipe 13, and the gas in the compressed gas cylinder 5 enters the first floating body 4 through the first connecting pipe 6 and the second connecting pipe 13, and the diving cage quickly floats up through the expansion of the first floating body 4;

[0058] At the same time, part of the gas in the first float 4 is transmitted to the bottom through the third connecting pipe 14, and enters the connecting block 16 through the second ball valve 28 and the first ball valve 23, and finally enters the second float 15 from the connecting block 16, so that the second float 15 is inflated to assist the diving cage to float up quickly;

[0059] During the buoyancy process, if an unstable factor is encountered and the diver needs to detach himself, the limit block 19 is first rotated, and the rotation of the limit block 19 drives the rotation of the first rotating shaft 20, and the rotation of the first rotating shaft 20 drives the rotation of the first gear 21, and the rotation of the first gear 21 drives the movement of the second rack plate 22, so that the two limit blocks 19 rotate at the same time, and the limit block 19 is rotated to coincide with the connecting groove in the installation belt 18, and then the installation belt 18 is removed from the limit block 19, and then the second float 15 is moved outward and taken out;

[0060] At the same time, the movement of the second floating body 15 drives the connecting shaft 26 to slide out of the cage body 1, and the connecting shaft 26 moves to separate from the fourth rack plate 31, and the second spring 33 releases the elastic potential energy to drive the slider 32 to move outward, and the movement of the slider 32 drives the movement of the fourth rack plate 31, and the movement of the fourth rack plate 31 drives the third gear 30 to rotate, and the rotation of the third gear 30 drives the third rotating shaft 29 to rotate, and the rotation of the third rotating shaft 29 drives the second ball valve 28 to rotate, so that the gas is no longer discharged;

[0061] The connecting shaft 26 moves outward to drive the second gear 25 to move, and the second gear 25 meshes with the third rack plate 27 to rotate. The rotation of the second gear 25 drives the rotation of the second rotating shaft 24, and the rotation of the second rotating shaft 24 drives the rotation of the first ball valve 23, so that the inside of the connecting block 16 is blocked, and the gas of the second floating body 15 does not leak;

[0062] Finally, after the second buoy 15 is removed, the second buoy 15 can be tied to the diver's body by the binding belt 17 to assist the diver in floating up.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
