Description

Technical Field

[0001] The present invention relates to the technical field of submersibles, and more particularly to a rescue buoy and a submersible. Background Art

[0002] Currently, when a submersible is in distress underwater and cannot surface normally, the operator in the submersible is required to manually release the rescue buoy. This rescue method has high requirements on the integrity of the submersible's internal systems and equipment. For example, the power supply system and communication system need to operate well so that rescue information can be sent out. Therefore, the requirements for the rescued submersible itself are high; or professional divers are sent to carry out underwater rescue. In this way, the requirements for the rescue submersible's ship are high and it is greatly affected by the sea conditions.

In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined. The following is a more detailed description of the specific implementation of the present invention in conjunction with specific embodiments:

[0045] like Figures 1 to 3 As shown, an embodiment of the present invention provides a rescue buoy, which is used to be set on a submersible 2 and can be released to the water surface at a fixed time when the submersible 2 performs a diving mission, so that rescuers can capture the rescue buoy and then rescue the submersible 2; the following is an explanation through a specific embodiment:

[0046] The rescue buoy of this embodiment includes: a release device 1 and a buoy device 3;

[0047] The release device 1 is used to connect to the submersible 2 and includes a timing drive assembly 11 and a locking assembly 12. Here, the release device 1 is used to be fixedly connected to the submersible 2 and is used to release the buoy device 3 after a set time has passed. Specifically, the release device 1 includes the timing drive assembly 11 and the locking assembly 12. The locking assembly 12 is used to connect to the buoy device 3. The timing drive assembly 11 is used to set a preset time. After the preset time, the locking assembly 12 is triggered to release the buoy device 3.

[0048] The buoy device 3 includes a drum 31, a connecting pipe 32, a first connecting member 33 and a second connecting member 34. The drum 31 is a buoyancy structure. The connecting pipe 32 is wound on the drum 31 and one end of the connecting pipe 32 is used to communicate with the ballast water tank 21 of the submersible 2. The first connecting member 33 connects the drum 31 and the other end of the connecting pipe 32. The second connecting member 34 connects the drum 31 and the locking assembly 12. Here, the buoy device 3 has the ability to float to the surface. Specifically, the drum 31 can float under the buoyancy of the water. Surfaced, the reel 31 is made of buoyant material; the connecting pipe 32 can be a hose that can be wound around the reel 31, one end of the connecting pipe 32 is used to connect and communicate with the ballast water tank 21 of the submersible 2, and the other end of the connecting pipe 32 is connected to the first connecting member 33; the first connecting member 33 is connected to the reel 31 to achieve the connection between the connecting pipe 32 and the reel 31; the second connecting member 34 is connected to the reel 31 and the locking assembly 12 to achieve the connection between the buoy device 3 and the release device 1;

[0049] The timing drive assembly 11 can drive the locking assembly 12 to disengage from the second connecting member 34 after exceeding a set time value.

[0050] The working principle of the rescue buoy provided in this embodiment is as follows:

[0051] The rescue buoy is installed on the submersible 2, wherein the release device 1 is fixed on the submersible 2, one end of the connecting pipe 32 is connected and communicated with the ballast water tank 21 of the submersible 2, the first connecting member 33 connects the other end of the connecting pipe 32 and the reel 31, and the second connecting member 34 connects the release device 1 and the reel 31; when the submersible 2 dives to perform a mission, it drives the rescue buoy to dive under the water surface together, and the timing drive component 11 is set to a preset time value, such as the time required to perform the mission, and a certain time is added to the time to set it as the preset time value. When the time for the submersible 2 to perform the mission exceeds the preset time value, the release device 1 is triggered to release the second connecting member 34. At this time, the reel 31 The connection with the submersible 2 is released, that is, it is separated from the submersible 2 and floats up. At the same time, one end of the connecting pipe 32 still remains connected to the ballast water tank 21 of the submersible 2. In this way, the reel 31 drives the other end of the connecting pipe 32 to float up under the action of buoyancy, and the connecting pipe 32 originally wound on the reel 31 is loosened from the reel 31 one by one until the reel 31 floats on the water surface; at this time, the rescue personnel can capture the reel 31 from the water surface, and then collect the reel 31 to the rescue boat, cut the other end of the connecting pipe 32 and inflate the connecting pipe 32, and use high-pressure air to press out the water in the ballast water tank 21. After the ballast water tank 21 is inflated, it drives the submersible 2 to automatically float up, thereby realizing the rescue and recovery of the submersible 2.

[0052] By adopting the above technical solutions:

[0053] First, the rescue buoy can be released at a fixed time, thus avoiding failure of the rescue operation due to failure of the internal system or equipment of the submersible 2;

[0054] Secondly, the rescue buoy can automatically float to the surface after being released, making it easier for rescuers to capture it. This avoids the need for rescuers to dive underwater in high sea conditions to carry out rescue operations, reducing the operational risks for rescuers.

[0055] Finally, the drum 31 can rely on buoyancy to drive the connecting pipe 32 to the rescue ship, and on the rescue ship, the ballast water tank 21 can be inflated to drive the submersible 2 to automatically float up, without the need for the rescue ship to use a winch to perform the pulling operation, thereby reducing the rescue team's rescue ship requirements and thus reducing the rescue cost.

[0056] like Figure 4 As shown, in one embodiment, the connecting pipe 32 includes a first connecting section 321 and a second connecting section 322 connected to the first connecting section 321. The first connecting section 321 and the second connecting section 322 are both wound on the reel 31. The first connecting section 321 is formed with a first connecting end 3211 for connecting to the ballast water tank 21 of the submersible 2, and the second connecting section 322 is formed with a second connecting end 3221 for connecting to the ballast water tank 21 of the submersible 2.

[0057] Here, the connecting pipe 32 is used to connect and connect the ballast water tank 21 of the submersible 2; specifically, the connecting pipe 32 includes a first connecting section 321 and a second connecting section 322. Optionally, the first connecting section 321 and the second connecting section 322 are wound on the drum 31 in layers, that is, one of the first connecting section 321 and the second connecting section 322 is wound on the inner layer of the drum 31, and the other of the first connecting section 321 and the second connecting section 322 is wound on the outer layer of the drum 31; the first connecting section 321 and the second connecting section 322 are both connected to and connected with the ballast water tank 21 of the submersible 2, and the first connecting section 321 is formed The first connecting end 3211 formed by the second connecting section 322 and the second connecting end 3221 formed by the second connecting section 322 are both located at one end of the connecting pipe 32 for connecting and connecting to the ballast water tank 21 of the submersible 2, and the other ends of the first connecting section 321 and the second connecting section 322 are connected to the reel 31, so that when the reel 31 can drive the first connecting section 321 and the second connecting section 322 to float, the first connecting section 321 and the second connecting section 322 are loosened from the reel 31 in turn, and the rescue personnel can capture the first connecting section and the second connecting section connected to the reel 31, and then carry out the inflation operation of the ballast water tank 21.

[0058] It can be understood that the first connecting section 321 and the second connecting section 322 can be used to inflate the ballast water tank 21. During the actual rescue process, the ballast water tank 21 may tilt as the submersible 2 moves in the water. In this way, the water in the ballast water tank 21 is tilted relative to the ballast water tank 21, thereby blocking the connecting pipe 32 and dividing the connecting pipe 32 into the first connecting section 321 and the second connecting section 322, so that the two are connected to the opposite sides of the ballast water tank 21 respectively. When the ballast water tank 21 tilts and causes the connecting pipe 32 on one side to be in the air part of the ballast water tank 21 and unable to drain, the connecting pipe 32 on the other side is kept connected to the water in the ballast water tank 21 to ensure the normal operation of the inflation operation.

[0059] By adopting the above technical solution, the reliability of the inflation operation of the connecting pipe 32 is improved.

[0060] In one embodiment, a fixed section 323 is formed between the first connecting section 321 and the second connecting section 322, and the fixed section 323 is fixedly connected to the first connecting member 33. The first connecting section 321 and the second connecting section 322 can be cut and separated at the fixed section 323 after the reel 31 floats to the surface, so that the first connecting section 321 is formed with a third connecting end 3212 for connecting with one of the inflation device and the drainage device, and the second connecting section 322 is formed with a fourth connecting end 3222 for connecting with the other of the inflation device and the drainage device.

[0061] Here, it needs to be further explained that in order to enable the water in the ballast water tank 21 to be discharged quickly and to increase the inflation speed, so as to increase the surfacing speed of the submersible 2, one of the first connecting section 321 and the second connecting section 322 is set as the inflation connecting section, and the other of the first connecting section 321 and the second connecting section 322 is set as the drainage connecting section; specifically, when the rescue personnel inflate one of the first connecting section 321 and the second connecting section 322, the water in the ballast water tank 21 will be discharged to the water surface through the other of the first connecting section 321 and the second connecting section 322. The pressure on the water surface is much smaller than the water pressure under the water surface. Therefore, such a design can reduce the difficulty of inflation and reduce the air pressure required for inflation.

[0062] By adopting the above technical solution, the difficulty of inflating the connecting pipe 32 is reduced, and the inflation speed of the connecting pipe 32 during rescue is increased, thereby increasing the ascent speed of the submersible 2.

[0063] In one embodiment, the first communication end 3211 and the second communication end 3221 are arranged on the ballast water tank 21 of the submersible 2 at a preset distance.

[0064] It is understandable that the ballast water tank 21 will tilt with the submersible 2. In this way, arranging the first connecting end 3211 and the second connecting end 3221 at intervals on the ballast water tank 21 can effectively prevent the first connecting end 3211 and the second connecting end 3221 from being unable to drain water; specifically, the first connecting end 3211 and the second connecting end 3221 are preferably connected to the top surface of the ballast water tank 21, and are respectively arranged at two opposite corners of the top surface. In this way, when the ballast water tank 21 tilts, at least one of the first connecting end 3211 and the second connecting end 3221 will be below the water surface of the ballast water tank 21 to achieve drainage operations. In this way, the other of the first connecting end 3211 and the second connecting end 3221 can achieve inflation operations. Rescuers can also judge the tilt state of the submersible 2 based on whether the first connecting end 3211 and the second connecting end 3221 can drain water. For example, when the rescuers inflate the first connecting section 321, if the second connecting section 322 cannot drain water, it means that the second connecting end 3221 is connected to the air part in the ballast water tank 21, that is, the ballast water tank 21 is tilted downward toward the first connecting section 321. At this time, it is necessary to switch to the second connecting section 322 for inflation; similarly, when the second connecting section 322 is inflating, if the first connecting section 321 cannot drain water, then it is judged that the ballast water tank 21 is tilted downward on the second connecting section 322 side, and the rescuers should switch the connecting section for inflation; the tilt state of the submersible 2 can be judged by the ballast water tank 21, which can also improve the rescue efficiency.

[0065] By adopting the above technical solution, the above design can enable rescue personnel to judge the tilt state of the ballast water tank 21, and then analyze the tilt state of the submersible 2, thereby improving the rescue efficiency.

[0066] In one embodiment, the first connecting end 3211 and the second connecting end 3221 are used to extend into the ballast water tank 21 of the submersible 2, and the distance between the first connecting end 3211 and the second connecting end 3221 and the bottom of the ballast water tank 21 of the submersible 2 is less than or equal to 10 cm.

[0067] Here, it can be understood that the first connecting end 3211 and the second connecting end 3221 are arranged close to the bottom of the ballast water tank 21, so that even if the ballast water tank 21 is tilted, the first connecting end 3211 and the second connecting end 3221 can be positioned as far as possible below the water surface of the ballast water tank 21, thereby ensuring the effectiveness of the drainage operation of the first connecting end 3211 and the second connecting end 3221.

[0068] By adopting the above technical solution, the reliability of the inflation and drainage operation of the connecting pipe 32 is improved.

[0069] In one embodiment, the reel 31 extends in the vertical direction, the first connecting end 3211 and the second connecting end 3221 are located on the lower side of the reel 31, the third connecting end 3212 and the fourth connecting end 3222 are located on the upper side of the reel 31, and the connecting tube 32 increases the number of winding turns from bottom to top in the vertical direction.

[0070] Here, since the drum 31 extends in the vertical direction, the drum 31 is arranged in an upright state on the ballast water tank 21, and the first connecting end 3211 and the second connecting end 3221 are located on the lower side of the drum 31, which is convenient for communicating with the ballast water tank 21. The third connecting end 3212 and the fourth connecting end 3222 are located on the upper side of the drum 31, which are used to connect with the top of the drum 31, and the winding direction of the connecting pipe 32 is from bottom to top, so that the connecting pipe 32 can be loosened from bottom to top in sequence when the drum 31 floats up, thereby keeping the drum 31 floating in an upward posture.

[0071] By adopting the above technical solution, the stability of the drum 31 during floating is improved, so that the connecting tube 32 can be loosened from the drum 31 in sequence, reducing the possibility of the connecting tube 32 being entangled during the floating process of the drum 31, and improving the reliability of the rescue buoy.

[0072] In one embodiment, the reel 31 has a reel hole 311 extending in the vertical direction, the second connecting member 34 is passed through the reel hole 311, the top end of the second connecting member 34 is connected to the top of the reel 31, and the bottom end of the second connecting member 34 is connected to the locking assembly 12.

[0073] By adopting the above technical solution, the above design can keep the reel 31 always in an upright state as the submersible 2 dives, which is conducive to the release of the buoy device 3.

[0074] like Figure 5 As shown, in one embodiment, the locking assembly 12 includes a locking lever 125 and a suspension rod 127 . The locking lever 125 is used to be fixed to the ballast water tank 21 and cooperates with the suspension rod 127 to fix or release the second connecting member 34 .

[0075] By adopting the above technical solution, the locking lever 125 and the suspension rod 127 have simple structures, and the two are easy to cooperate with each other to achieve the fixation and release of the second connecting member 34, thereby achieving the fixation and release of the buoy device 3.

[0076] In one embodiment, the locking assembly 12 includes a bracket 121 for being fixed on the ballast water tank 21 of the submersible 2, a first rotating shaft 122, a second rotating shaft 123 and a third rotating shaft 124 arranged in parallel and spaced order on the bracket 121, a locking lever 125 arranged on the first rotating shaft 122, a cam 126 arranged on the second rotating shaft 123, and a suspension rod 127 arranged on the third rotating shaft 124, the suspension rod 127 and the cam 126 are connected to fix the second connecting member 34, the timing drive assembly 11 is arranged on the bracket 121 and is used to drive the locking lever 125 to rotate around the first rotating shaft 122, triggering the cam 126 to rotate around the second rotating shaft 123 to release the connection with the suspension rod 127, so that the suspension rod 127 can rotate freely around the third rotating shaft 124 to release the second connecting member 34.

[0077] Here, in this embodiment, the second connecting member 34 is a connecting rope having a connecting ring for being sleeved on the suspension rod 127. It should be further explained that when the cam 126 rotates about the second rotating shaft 123 to release the connection with the suspension rod 127, a gap is formed between the cam 126 and the suspension rod 127, allowing the connecting ring to detach from the suspension rod 127 and float up with the sleeve.

[0078] It needs to be further explained that, in actual application scenarios, the locking lever 125 can directly trigger the starting suspension rod 127, or can trigger the starting suspension rod 127 through other components such as the cam 126 in the above embodiment.

[0079] By adopting the above technical solution, the locking assembly 12 has a simple structure and high reliability.

[0080] In one embodiment, the timing drive assembly 11 includes a drive motor, a battery, a relay, and a circuit board that are electrically connected in sequence, and the drive motor is connected to the locking member.

[0081] By adopting the above technical solution, the timing drive assembly 11 has a simple structure and high reliability.

[0082] In a second aspect, a submersible 2 is provided, which is provided with the above-mentioned rescue buoy, and the ballast water tank 21 of the submersible 2 is connected to the connecting pipe 32.

[0083] By adopting the above technical solution, on the basis of having the advantages of the rescue buoy of the above embodiment, the submersible 2 of this embodiment has the advantages of high rescue efficiency and low requirements for rescue operations.

[0084] In one embodiment, the rescue buoy may also be provided with a signal light or a communication signal device to facilitate subsequent rescue personnel to quickly find the rescue buoy.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
