Description

Technical Field

[0001] This invention relates to the field of ship rescue, specifically to a small ship capsizing rescue device. Background Technology

[0002] In the field of marine lifesaving, small vessels are prone to capsizing when encountering emergencies such as wind, waves, or collisions. The rapid response and effective release of lifesaving devices during capsizing are crucial to ensuring the safety of the people on board.

[0003] Currently, traditional small boat lifesaving devices generally have the following shortcomings:

[0004] Release methods rely on manual operation: Most life-saving devices (such as life rafts) require manual triggering for release. However, when a ship capsizes, people may be unable to operate them in time due to panic or being trapped, causing the life-saving devices to miss the optimal release opportunity.

[0005] Slow response speed: Some automatic release devices rely on electric or hydraulic drive, and when the ship capsizes and causes a power system failure, the release may fail. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a small ship capsizing rescue device.

[0007] A small ship capsizing rescue device includes a support frame located on both sides of the ship, with rescue components installed in both support frames. It also includes a drive device installed on the ship, which can simultaneously drive the two support frames to rotate in the same direction during ship capsizing, with the rotation direction of the support frames opposite to the ship's capsizing direction. Above the drive device is a release frame with its ends located at both ends of the ship. The release frame is hinged to the support frame and can eject the rescue components in a lower position during ship capsizing. The bottom of the support frame is provided with a high-position release mechanism that can release the rescue components in a higher position during ship capsizing.

[0008] As an improvement, the drive unit includes a drive box located on the ship, with through slots at both ends of the drive box and a transmission rod passing through the through slots inside the drive box. The release frame includes two supports fixed to both ends of the ship. The support frame includes a hinge plate hinged to the supports. A hinge seat is provided at the bottom of the hinge plate. The end of the transmission rod is hinged to the hinge seat. The drive box is provided with a drive mechanism that drives the transmission rod to move inside the drive box, thereby causing the hinge plate to rotate.

[0009] As an improvement, the drive box is provided with a partition on one side of the transmission rod. The drive mechanism includes a worm gear located inside the drive box and on the other side of the transmission rod. The transmission rod inside the drive box has a tooth groove at the end near the worm gear. A transmission gear post that meshes with the tooth groove is fixed on the worm gear. A worm is provided on one side of the worm gear and meshes with the worm gear. A driven gear is provided at the end of the worm near the partition. A tilting and following mechanism that can drive the transmission rod to move through the driven gear is provided inside the drive box on the other side of the partition.

[0010] As an improvement, the tilting and following mechanism includes a load block that slides inside the drive box. The drive box is provided with a slide rod 1 that is slidably connected to the load block. The bottom end of the load block is provided with a groove. The top of the inner wall of the groove is provided with a tooth groove 2. The groove is provided with a transmission gear column 2 that meshes with the tooth groove 2. The shaft of the transmission gear column 2 passes through the partition and the end is provided with a drive gear that meshes with the driven gear.

[0011] During the capsizing process, the load-bearing block moves downward under the action of gravity, and the transmission rod moves downward under the action of the load-bearing block, thereby driving the support frame to rotate in the opposite direction to the capsizing direction of the ship.

[0012] As an improvement, the support frame also includes a support frame hinged to the other end of the hinge plate. The life-saving component includes a life raft body placed in the support frame. The bottom end of the life raft body is provided with a positioning base that abuts against the bottom of the support frame. The bottom of the support frame is provided with a pull line placement groove. A pull line body is coiled in the pull line placement groove. The two ends of the pull line body are respectively connected to the life raft body and the support frame.

[0013] The high-position release mechanism can limit the load-bearing frame relative to the hinge plate, preventing the load-bearing frame from rotating downwards. During the capsizing process, the load-bearing frame in the high position rotates downwards. As the load-bearing frame rotates downwards, the high-position release mechanism comes into contact with the side wall of the ship, thereby releasing the load-bearing frame and causing it to rotate downwards to release the life raft body.

[0014] As an improvement, the high-position release mechanism includes a base and a slot corresponding to the bottom of the support frame and the hinge plate. A limit rod is slidably inserted into the base. One end of the limit rod near the hinge plate is inserted into the slot, and the other end is provided with an end block. A spring three located between the end block and the base is sleeved on the limit rod. A limit mechanism that can limit the limit rod is provided on the hinge plate. When the limit mechanism limits the limit rod, the spring three is in a compressed state.

[0015] As an improvement, the limiting mechanism includes a slide bar II located on the hinge plate, a slider is slidably sleeved on the slide bar II, a limiting block II is provided at the top, a spring IV located between the slider and the limiting block II is sleeved on the slide bar II, and an insert plate and a force rod are respectively provided at both ends of the slider that pass through the hinge plate. The bottom end of the insert plate is inserted into the limiting rod, and the bottom end of the force rod is provided with an upwardly inclined auxiliary rod. An auxiliary roller is provided on the auxiliary rod. When the support frame rotates downward, the auxiliary roller contacts the side wall of the ship and rolls on the side wall.

[0016] As an improvement, the release frame also includes a trapezoidal frame fixed between two supports. A track is fixed to the side wall of the frame, and a cavity is provided inside. A spring is installed in the cavity. A limiting plate is located at the top of the spring and inside the cavity. A limiting block is installed on the limiting plate, which passes through the through hole at the top of the cavity. A spring is installed at the bottom of the track. A pushing block is installed at the end of the spring that slides in the track and abuts against the limiting block. A folding rod is installed at the top of the life raft body. When the support frame rotates upward, the folding rod abuts against the limiting block and compresses the spring. At this time, the pushing block, under the action of the spring, drives the life raft body to be thrown out of the support frame.

[0017] The advantages of this invention compared to the prior art are as follows:

[0018] 1. This invention drives the two side support frames to rotate in the same direction when the ship capsizes, and the rotation direction is opposite to the ship's capsizing direction. This causes the support frame in the lower position to rotate upward and cooperate with the release frame to eject the life-saving device, while the support frame in the higher position rotates downward and releases the life-saving device through the high-position release mechanism. This realizes the bidirectional automatic release of the life-saving device during the ship's capsizing process, effectively improving the response speed and rescue efficiency of the life-saving device.

[0019] 2. The hinged design of the release frame and the support frame, as well as the internal spring structure, enable the life raft body to be thrown out of the support frame by the compression of the spring through the contact between the folding rod and the first limiting block when the support frame rotates upward. This ensures that the life raft can quickly detach from the ship and unfold when the ship capsizes, giving the people on board more time to escape.

[0020] 3. The tilting and following mechanism inside the drive unit uses the gravity of the load block to move downwards when the ship capsizes. Through a series of gears and worm gears, it drives the transmission rod to move, thereby driving the support frame to rotate. This design does not require an additional power source and can be triggered solely by the gravity of the ship when it capsizes, ensuring the reliability and stability of the device in emergency situations.

[0021] 4. The high-position release mechanism, through the cooperation of the base, limit rod, spring three and the limit mechanism, when the support frame rotates downward, the auxiliary roller contacts and rolls with the side wall of the ship, pushing the force rod to drive the slider to move, so that the insert plate is pulled out from the limit rod. Under the action of spring three, the limit rod disengages from the slot, realizing the release of the limit on the support frame, ensuring that the life raft in the high position can fall quickly under the action of gravity.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 As shown:

[0037] A small ship capsizing rescue device includes a support frame 1 located on both sides of the ship, with a rescue component 2 installed in each of the two support frames 1. It also includes a drive device 3 installed on the ship. During the ship capsizing process, the drive device 3 can simultaneously drive the two support frames 1 to rotate in the same direction, and the rotation direction of the support frames 1 is opposite to the ship capsizing direction. Above the drive device 3, there is a release frame 4 with its ends installed at both ends of the ship. The release frame 4 is hinged to the support frame 1 and can eject the rescue component 2 in a low position during the ship capsizing process. The bottom end of the support frame 1 is provided with a high-position release mechanism 6 that can release the rescue component 2 in a high position during the ship capsizing process.

[0038] The working principle of this invention is as follows: During the capsizing of a small vessel, the drive device 3 moves downward under the force of gravity during the capsizing and simultaneously drives the two support frames 1 to rotate in the same direction. The rotation direction of the support frames 1 is opposite to the capsizing direction of the vessel, that is, the support frame 1 in the lower position rotates upward and the support frame 1 in the higher position rotates downward. When the upward rotating support frame 1 comes into contact with and is squeezed by the release frame 4, the release frame 4 can drive the support frame 1 in the lower position to move in a straight line along the release frame 4 and be thrown out from the release frame 4. At the same time, the support frame 1 in the higher position rotates downward. During the process, the high-position release mechanism 6 comes into contact with and is squeezed by the side wall of the vessel. When the support frame 1 rotates downward to a certain extent, the high-position release mechanism 6 is released from the restriction of the support frame 1, causing the life-saving device 2 to fall.

[0039] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 Appendix Figure 10 Appendix Figure 11 Appendix Figure 12 As shown:

[0040] The release frame 4 includes two supports 402 fixed to both ends of the ship. The support frame 1 includes a hinge plate 101 hinged to the supports 402. The support frame 1 also includes a support frame 104 hinged to the other end of the hinge plate 101. The life-saving component 2 includes a life raft body 201 placed in the support frame 104. The bottom end of the life raft body 201 is provided with a positioning base 202 that abuts against the bottom of the support frame 104. The bottom of the support frame 104 is provided with a pull line placement groove 105. The pull line body 204 is coiled in the pull line placement groove 105. The two ends of the pull line body 204 are respectively connected to the life raft body 201 and the support frame 104.

[0041] The high-position release mechanism 6 can limit the bearing frame 104 relative to the hinge plate 101 to prevent the bearing frame 104 from rotating downward. During the capsizing process, the bearing frame 1, which is in a high position, rotates downward. During the downward rotation of the bearing frame 1, the high-position release mechanism 6 contacts the side wall of the ship, thereby releasing the high-position release mechanism 6 from the limitation of the bearing frame 104, causing the bearing frame 104 to rotate downward and thus releasing the life raft body 201.

[0042] The release frame 4 also includes a trapezoidal frame 401 fixed between two supports 402. A track 407 is fixed to the side wall of the frame 401, and a cavity 403 is provided inside. A spring 404 is provided in the cavity 403. A limiting plate 405 located in the cavity 403 is provided at the top of the spring 404. A limiting block 406 passing through the through hole at the top of the cavity 403 is provided on the limiting plate 405. A spring 408 is provided at the bottom of the track 407. A pushing block 409 is provided at the end of the spring 408 that slides in the track 407 and abuts against the limiting block 406. A folding rod 203 is provided at the top of the life raft body 201. When the support frame 1 rotates upward, the folding rod 203 abuts against the limiting block 406 and compresses the spring 404. At this time, the pushing block 409, under the action of the spring 408, drives the life raft body 201 to be thrown out of the support frame 104.

[0043] During the capsizing of the small vessel, the support frame 104 and hinge plate 101 on the lower support frame 1 rotate upwards simultaneously. When the rotation reaches a certain angle, the folding rod 203 at the top of the life raft body 201 abuts against the limiting block 406 and presses the limiting block 406 into the cavity 403, compressing the spring 404. When the top of the limiting block 406 is flush with the frame 401, the limiting block 406 disengages from the pushing block 409. When the limiting block 406 abuts against the pushing block 409, the spring 408 is in a compressed state, that is, when the limiting block 406 disengages from the pushing block 409, the pushing block 409 is under the action of the spring 408. The life raft body 201 slides rapidly upward along the track 407. During this process, the push block 409 can drive the life raft body 201 to detach from the support frame 104 and move upward along the track 407 via the folding rod 203. When the push block 409 moves upward into position, the life raft body 201 continues to move upward under the action of inertia. During the upward movement, the pull line body 204 is gradually straightened. When straightened, the pull line body 204 and the life raft body 201 automatically unfold and inflate under the relative force. The life raft body 201, which has detached from the small boat and automatically inflated, automatically falls into the water, thus facilitating the rescue of people who have fallen into the water.

[0044] The support frame 104 and the hinge plate 101 on the high-position support frame 1 rotate downwards simultaneously. During the downward rotation of the support frame 1, the high-position release mechanism 6 contacts the side wall of the ship, thereby causing the high-position release mechanism 6 to disengage from the limit of the support frame 104. At this time, the support frame 104 can rotate downwards rapidly relative to the hinge plate 101 under the action of gravity. Since the support frame 104 will sway when it rotates downwards, the life raft body 201 will fall downwards from the support frame 104 under the downward rotation and swaying action of the support frame 104. During the downward fall, the pull line body 204 is gradually straightened. When straightened, the pull line body 204 and the life raft body 201 automatically unfold and inflate under the relative force between them.

[0045] The life raft body 201 is specifically a ship emergency life raft and is existing technology. The specific principle is as follows: the life raft body 201 has a built-in high-pressure gas cylinder and an inflatable life raft. The pull cable body 204 is connected to the triggering mechanism (such as a puncture valve) of the high-pressure gas cylinder. The puncture valve generally includes a lever assembly and a puncture assembly. When a pulling force is generated between the pull cable body 204 and the lever assembly, the pulling force drives the lever assembly to work. The lever assembly drives the puncture assembly (such as a puncture needle) to puncture the sealing membrane of the high-pressure gas cylinder. The gas in the high-pressure gas cylinder fills the air chamber of the raft body within a few seconds to make the air chamber of the raft body quickly inflated.

[0046] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 Appendix Figure 10 As shown:

[0047] The high-position release mechanism 6 includes a base 601 and a slot 613 corresponding to the bottom of the support frame 104 and the hinge plate 101. A limit rod 602 is slidably inserted into the base 601. One end of the limit rod 602 near the hinge plate 101 is inserted into the slot 613, and the other end is provided with an end block 603. A spring 604 located between the end block 603 and the base 601 is sleeved on the limit rod 602. The hinge plate 101 is provided with a limiting mechanism that can limit the limit rod 602. When the limiting mechanism limits the limit rod 602, the spring 604 is in a compressed state.

[0048] The limiting mechanism includes a slide bar 605 located on the hinge plate 101. A slider 607 is slidably sleeved on the slide bar 605. A limiting block 606 is provided at the top. A spring 608 located between the slider 607 and the limiting block 606 is sleeved on the slide bar 605. The slider 607 has an insert plate 609 and a force rod 610 at both ends that pass through the hinge plate 101. The bottom end of the insert plate 609 is inserted into the limiting rod 602. The bottom end of the force rod 610 is provided with an upwardly inclined auxiliary rod 612. An auxiliary roller 611 is provided on the auxiliary rod 612. When the support frame 1 rotates downward, the auxiliary roller 611 contacts the side wall of the ship and rolls on the side wall.

[0049] Working principle of high-position release mechanism 6: When one side of the support frame 1 rotates downward, the auxiliary roller 611 contacts the side wall of the ship and rolls on the side wall. During the process, the side wall applies pressure to the force rod 610 through the auxiliary roller 611. At this time, the force rod 610 moves upward to the hinge plate 101 under the action of pressure. The force rod 610 drives the insert plate 609 to move through the slider 607. When the insert plate 609 moves upward to the hinge plate 101, it is gradually pulled out from the limit rod 602. Since the spring 604 is in a compressed state when the insert plate 609 is inserted into the limit rod 602, when the insert plate 609 is completely pulled out from the limit rod 602, the limit rod 602 moves rapidly away from the hinge plate 101 under the action of the spring 604. After it is in place, the limit rod 602 is completely below the support frame 104. At this time, the support frame 104 can rotate downward rapidly under the action of gravity.

[0050] The high-position release mechanism 6 in this invention is mainly used to quickly release the downward rotating life raft body 201, while the upward rotating support frame 1 is always limited by the high-position release mechanism 6.

[0052] The drive unit 3 includes a drive box 301 located on the ship. Both ends of the drive box 301 are provided with through slots 302 and a transmission rod 304 passing through the through slots 302 is provided inside the drive box 301. The bottom of the hinge plate 101 is provided with a hinge seat 102. The end of the transmission rod 304 is hinged to the hinge seat 102. The drive box 301 is provided with a drive mechanism that drives the hinge plate 101 to rotate by moving the transmission rod 304 inside the drive box 301.

[0053] The drive box 301 is provided with a partition 303 located on one side of the transmission rod 304. The drive mechanism includes a worm gear 306 located in the drive box 301 and on the other side of the transmission rod 304. The transmission rod 304 located in the drive box 301 is provided with a tooth groove 305 at the end near the worm gear 306. A transmission gear column 307 that meshes with the tooth groove 305 is fixedly connected to the worm gear 306. A worm 308 that meshes with the worm gear 306 is provided on one side of the worm gear 306. A driven gear 309 is provided at the end of the worm 308 near the partition 303. A tilting and following mechanism that can drive the transmission rod 304 to move through the driven gear 309 is provided in the drive box 301 on the other side of the partition 303.

[0054] The tilting and following mechanism includes a load block 311 that slides inside a drive box 301. A slide rod 310 that slides through the load block 311 is provided inside the drive box 301. A groove 312 is provided at the bottom of the load block 311. A toothed groove 313 is provided at the top of the inner wall of the groove 312. A transmission gear column 314 that meshes with the toothed groove 313 is provided inside the groove 312. The shaft of the transmission gear column 314 passes through the partition 303 and has a drive gear 315 that meshes with the driven gear 309 at its end.

[0055] During the capsizing process, the load block 311 moves downward under the action of gravity, and the transmission rod 304 moves downward under the action of the load block 311, thereby driving the support frame 1 to rotate in the opposite direction to the capsizing direction of the ship.

[0056] Working principle of drive device 3: When the ship capsizes to one side, the load block 311 moves in the capsizing direction under the action of gravity. The load block 311 drives the drive gear 315 to rotate through the transmission gear column 2 314. The drive gear 315 drives the worm 308 to rotate through the driven gear 309. The worm 308 drives the transmission gear column 1 307 to rotate through the worm wheel 306. The transmission gear column 1 307 drives the transmission rod 304 to move in the same direction as the load block 311 through the tooth groove 305. That is, it moves downward relative to the capsized ship, so that the support frame 1 located below rotates upward and the support frame 1 located above rotates downward.

[0057] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 7 Appendix Figure 11 As shown:

[0058] The hinge seat 102 is provided with a cable seat 103, and an auxiliary connecting cable 5 is connected between the two cable seats 103. The auxiliary connecting cable 5 passes through the frame 401 and is located on the roller provided on the lower end surface of the frame 401. Both ends of the drive box 301 are provided with protective shells 316 that are sleeved on the outside of the transmission rod 304.

[0059] In a specific implementation of the present invention: when the ship capsizes, the load-bearing block 311 moves downward under the action of gravity, and the transmission rod 304 moves downward through the transmission gear column 314, which drives the bearing frame 1 to rotate in the opposite direction to the ship capsizing, that is, the lower bearing frame 1 rotates upward and the higher bearing frame 1 rotates downward. On the upward-rotating support frame 1, the folding bar 203 at the top of the life raft body 201 abuts against the limiting block 406 of the release frame 4. The pushing block 409, under the action of the second spring 408, drives the life raft body 201 to detach from the support frame 104 and throw it out. When thrown out, the pull line body 204 straightens, triggering the life raft to inflate. On the downward-rotating support frame 1, the high-position release mechanism 6 contacts the side wall of the ship. The force rod 610 drives the slider 607 to pull the insert plate 609 out of the limiting rod 602. Under the action of the third spring 604, the limiting rod 602 disengages from the slot 613. The support frame 104 rotates under gravity. When the life raft body 201 falls, the pull line body 204 straightens, triggering inflation, thereby realizing the automatic release and deployment of the life raft when the ship capsizes.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
