Description

Technical Field

[0001] The invention relates to the technical field of diving cages, in particular to a high-safety diving cage used for underwater diving operations. Background Art

[0002] High-security diving cages for underwater diving operations are a type of safety equipment used for underwater operations. They are mainly used to protect divers from dangerous factors in the water, such as attacks by marine life, strong currents, or various risks that may be encountered in industrial environments. Diving cages are widely used in various underwater engineering activities, such as seabed construction and maintenance, salvage operations, marine biology research, and underwater photography and filmmaking.

[0003] However, because most of the existing submersible cages are installed on the hull or the operating water vehicle, and dive to a predetermined depth by hoisting for suspended operations, when the existing submersible cages are actually used, the hull or the operating water vehicle will still have a small amplitude of ups and downs and translation even if it is fixed with an anchor, and the hoisted submersible cage will change position with the ups and downs, increasing the difficulty of some precision operations underwater. As a result, it is inconvenient for the existing submersible cages that are hoisted and dived to reduce the impact of wind and waves by increasing the function of the cage body and the connection method of the hoisting equipment. At the same time, when the existing submersible cages are suspended at a predetermined position underwater, when they encounter the influence of undercurrents in the water, the submersible cages will have a small amplitude of pendulum swing or tilt in any direction. At this time, the divers in the submersible cages need to wait for the submersible cage to be relatively stable before they can continue to work, which increases the difficulty of the divers' work. As a result, it is inconvenient to maintain the vertical stability of the submersible cages when the existing submersible cages are suspended underwater to increase the stability of the submersible cages during suspended operations.

Detailed implementation manners

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: Please refer to Figures 1 to 10 , the present invention provides a technical solution: a highly safe diving cage for underwater diving operations. A first winch 2 is installed at the upper rear end of the hanger 1. The first winch 2 is connected to a first movable block 3 through a rope. The first movable block 3 is arranged below the front side of the hanger 1. A first movable sleeve 4 is movably sleeved outside the first movable block 3. The bottom of the first movable sleeve 4 is connected to an installation top 6. Pressure tanks 7 are installed in the grooves on the front and rear sides of the installation top 6. Placement cavities 8 are formed on the left and right sides of the installation top 6. An airbag is arranged in the placement cavity 8. The airbag in the placement cavity 8 is connected to the pressure tank 7 through a hose. A cage frame 9 is arranged at the bottom of the installation top 6. The bottom of the cage frame 9 is connected to an installation base 10. An installation sleeve 11 is fixed at the bottom of the inner cavity of the installation base 10. A second movable sleeve 12 is installed at the bottom of the inner cavity of the installation sleeve 11. A second movable block 13 is movably connected to the inner side of the second movable sleeve 12. A connecting frame 16 is arranged below the installation sleeve 11. An anchor seat 15 is fixed at the lower end of the connecting frame 16. A second winch 14 is installed in the groove at the top of the anchor seat 15. The second winch 14 is connected to the lower end of the second movable block 13 through a rope. A limiting component 5 is arranged between the first movable block 3 and the first movable sleeve 4 and between the second movable sleeve 12 and the second movable block 13;

[0035] The limiting component 5 includes a limiting groove 51. The limiting groove 51 is opened on the outer sides of the first movable block 3 and the second movable block 13. A limiting block 52 is movably connected to the inner side of the limiting groove 51. The limiting block 52 is installed in the groove on the inner side of the first movable sleeve 4 and the second movable sleeve 12. The limiting groove 51 is opened in an arc structure. The arc of the limiting groove 51 corresponds to the spherical structures of the first movable block 3 and the second movable block 13. One end of the limiting block 52 is designed as a spherical structure. The limiting component 5 is used for rotational limiting of the first movable sleeve 4 and the second movable sleeve 12. The first movable block 3 and the second movable block 13 are designed as spherical structures. The inner grooves of the first movable sleeve 4 and the second movable sleeve 12 correspond to the spherical structures of the first movable block 3 and the second movable block 13;

[0036] When the diving cage is in suspended operation, the vertical position of the cage frame 9 during operation is maintained through the anchor seat 15. The pressure tank 7 is set to inflate the airbag in the placement cavity 8 so that the installation top 6 and the cage frame 9 float upward. With the movable connection between the first movable block 3 and the first movable sleeve 4 and the rope adjustment of the first winch 2, when the hanger 1 is installed on the hull or waterborne carrier and sways and translates due to wind and waves, the influence on the cage frame 9 is reduced.

[0037] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 1 to 13 , the detection component 17 is arranged between the mounting sleeve 11 and the second movable block 13. The detection component 17 includes a mounting block 171, the mounting block 171 is fixed on the top of the second movable block 13, and a plurality of sliding tubes 172 are circumferentially installed on the outer side of the second movable block 13. A plug body 173 is slidably connected to the inner side of the sliding tube 172. The inner end of the plug body 173 is connected to a pressure sensor 174 through a spring. The pressure sensor 174 is arranged on the inner side of the sliding tube 172. The outer end top of the plug body 173 abuts against the inner side wall of the mounting sleeve 11. The sliding tubes 172 are equally angularly distributed in the mounting sleeve 11, and the interior of the mounting sleeve 11 is designed as a frustum-shaped structure. The detection component 17 is used for detecting the inclination direction and inclination angle of the mounting sleeve 11;

[0038] The adjusting component 18 is arranged on the outer side of the mounting base 10. The adjusting component 18 includes an internal gear ring 181. The internal gear ring 181 is sleeved on the outer side below the mounting base 10. A sliding block 183 is slidably sleeved on the outer side of the internal gear ring 181. The sliding block 183 is connected to a gear disk 182 through a motor. The tooth opening of the internal gear ring 181 is arranged on the inner side of the upper end. The tooth opening of the internal gear ring 181 meshes with the gear disk 182. A propulsion device 184 is installed at the lower end of the sliding block 183. The adjusting component 18 is used for adjusting the position of the mounting base 10;

[0039] When the cage 9 encounters an underwater undercurrent during underwater suspension operation, causing the cage 9 to tilt slightly, the mounting sleeve 11 tilts synchronously and adjusts the spring resistance of the plurality of plug bodies 173 sliding in the sliding tubes 172. The spring resistance data is collected in cooperation with the pressure sensor 174. The inclination direction and inclination angle of the cage 9 are analyzed through the control system. Then, the motor of the gear disk 182 is turned on through the control system. After adjusting the position of the sliding block 183 on the internal gear ring 181 to the position opposite to the inclination direction, the thrust of the propulsion device 184 is adjusted according to the value detected by the pressure sensor 174 to reset the position of the tilted cage 9. At the same time, the activities between the first movable block 3 and the first movable sleeve 4, and the activities between the second movable sleeve 12 and the second movable block 13 are limited by the cooperation of the limiting groove 51 and the limiting block 52, so that the cage 9 will not rotate due to the undercurrent during circumferential movement.

[0040] Working principle: When using this high-safety diving cage for underwater diving operations, first, the operator opens the first winch 2 through the control system to release the rope for hoisting and lowering operation. When the cage 9 is lowered to the underwater suspension operation position, the first winch 2 is closed for position fixing. Then, the second winch 14 is opened to release the rope so that the anchor seat 15 and the connecting frame 16 move downward to the bottom position for fixing, completing the hoisting adjustment of the operation position of the cage 9;

[0041] On this basis, when the hull or working carrier where the hanging bracket 1 is installed encounters relatively large wind and waves and undergoes a certain amount of undulation and movement, the operator turns on the air pressure tank 7 through the control system to inflate the airbag in the placement cavity 8. When the airbag in the placement cavity 8 expands to a state where it can drive the installation top 6, the cage frame 9, and its operating personnel and equipment to float, the air pressure tank 7 is closed. As a result, the cage frame 9 is kept perpendicular to the anchor seat 15 through the buoyancy and the connection of the rope of the first winch 2. At this time, the first winch 2 releases the corresponding rope allowance for undulation and translation according to the size of the wind and waves on the water surface. Then, in cooperation with the movable connection between the first movable block 3 and the first movable sleeve 4, when the hull or working carrier driven by the wind and waves causes the rope of the first winch 2 to displace, the first movable block 3 moves circumferentially correspondingly within the first movable sleeve 4, without causing pulling and tilting effects on the installation top 6 and the cage frame 9;

[0042] On this basis, when the submersible cage is suspended for operation and encounters underwater undercurrents, since the lower end of the cage frame 9 is circumferentially movably connected through the second movable sleeve 12 and the second movable block 13 in the installation sleeve 11, when the cage frame 9 encounters an undercurrent and tilts, the cage frame 9 drives the installation sleeve 11 and the second movable sleeve 12 through the installation base 10 to tilt correspondingly on the second movable block 13 along the tilting direction. At the same time, during this process, when the installation sleeve 11 tilts, its position changes, causing the inner upper conical cavity wall of the installation sleeve 11 to cause multiple plug bodies 173 to squeeze the springs inward in the sliding tubes 172 according to the direction and angle of tilting. Multiple pressure sensors 174 detect the change in the pressure value brought by the springs and collect data. Among the data detected by the multiple pressure sensors 174, the one with the largest pressure value indicates the tilting direction of the cage frame 9, and the pressure value indicates the tilting angle. These data are sent to the control system, and after analysis by the control system, the motor of the gear disk 182 is turned on to adjust the position of the sliding block 183 on the internal gear ring 181, so that the propulsion device 184 is adjusted to the opposite position of the tilting direction detected and analyzed by the pressure sensor 174. Then, through the control system, the propulsion device 184 is turned on, and based on the detected value of the pressure sensor 174, the thrust of the propulsion device 184 is adjusted correspondingly, so that the propulsion device 184 starts the corresponding thrust to quickly correct the position of the tilted cage frame 9;

[0043] At the same time, during the above process, when the first movable block 3 and the second movable block 13 move within the first movable sleeve 4 and the second movable sleeve 12 respectively, the limit block 52 can move along the direction in which the limit groove 51 is opened. Synchronously, the limit groove 51 can rotate on the limit block 52, restricting the rotation of the first movable block 3 and the second movable block 13 within the first movable sleeve 4 and the second movable sleeve 12, thereby maintaining the stability of the position of the cage frame 9.
