Description

Technical Field

[0001] The invention relates to a rescue device, in particular to a self-balancing rescue device for marine rescue. Background Art

[0002] During maritime rescue, due to the vast sea area, rescuers generally need to use ships and other rescue equipment to carry out rescue operations.

[0003] For example, a self-balancing rescue device for marine rescue disclosed in a Chinese patent with the publication number CN118529213A includes a side handle, a rubber boat, a rescue seat, and a water-retaining tent. The water-retaining tent is installed at the upper end of the rubber boat, the side handle is embedded in the outer side of the rubber boat, and the rescue seat is located at the upper inner side of the rubber boat. In the present invention, the impact of seawater drives the force-bearing block to move. Under the deformation elastic force of the force-bearing block, the upward impact of seawater is converted into a force that pushes the arc plate to the right, and then the upward impact force is converted into a rightward moving force, thereby preventing the upward impact of seawater from generating an upward impulse, avoiding the overturning caused by excessive upward impact of seawater, and enhancing its stability. After the second spring is compressed and tilted, the support block connected to the connecting rod is pressed downward under gravity, and then the side of the load-bearing plate that is impacted by seawater sinks and balances, so that the upper gravity follows the impact of seawater for automatic balance, preventing the balance from being too slow when the seawater impacts, and preventing the gravity from balancing too slowly on the load-bearing plate and causing imbalance. The patent has the following problems:

[0004] First, using traditional rubber boats as the main body, although the rubber boats are light and convenient, their corresponding carrying capacity is limited. The internal balancing mechanism and other components will increase the weight of the hull, which will further reduce the carrying capacity of the rubber boat;

[0005] Second, the self-balancing mechanism is set inside the rubber boat. One of the main advantages of the rubber boat is that it can be inflated and deflated and is portable. However, setting components inside the rubber boat cavity will cause the rubber boat as a whole to be unable to be folded for storage and transportation after being deflated. Summary of the invention

[0006] The object of the present invention is to provide a self-balancing rescue device for marine rescue, so as to solve the existing problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solution: a self-balancing rescue device for marine rescue, comprising a rubber boat, and further comprising:

[0008] A cross connector, wherein connection holes are provided near the edges of the four corners of the cross connector, a plug-in column is fixedly connected to the bottom of the rubber boat, the plug-in column and the connection hole cooperate with each other, and a threaded connection sleeve is fixedly connected to the bottom of the cross connector near the center;

[0009] A buoyancy stabilization mechanism, the buoyancy stabilization mechanism is connected to the positions on both sides of the cross connection member, the buoyancy stabilization mechanism comprises a connecting rod and a buoy, and the buoy is fixedly connected to one end of the connecting rod;

[0010] The balancing mechanism includes a connecting sleeve and a connecting column. The connecting column is slidably installed in the connecting sleeve. The upper end of the connecting sleeve is fixedly connected with a threaded connector, and the threaded connector is threadedly matched with the threaded connecting sleeve. The lower end of the connecting column is fixedly connected with a counterweight ball.

[0011] Preferably, a limiter is fixedly connected to the lower side of the cross connector, a limiter groove is provided under the limiter, and a return spring is fixedly connected in the limiter groove.

[0012] Preferably, the other end of the return spring is fixedly connected to a limit pin, a limit hole is provided in the plug column, the limit pin and the limit hole cooperate with each other, and a displacement handle is fixedly connected to the return spring.

[0013] Preferably, a T-shaped slide rail is fixedly connected symmetrically to the lower side of the cross connector.

[0014] Preferably, a T-shaped slide groove is provided at the other end of the buoyancy stabilizing mechanism, and the T-shaped slide groove is slidably matched with the T-shaped slide rail.

[0015] Preferably, a threaded sleeve block is embedded and installed under the connecting rod, and a fixing bolt is installed in the inner thread of the threaded sleeve block, and the fixing bolt cooperates with the limiting clamping hole.

[0016] Preferably, a limiting protrusion is fixedly connected to the inner wall of the connecting sleeve, and a limiting sliding groove is provided on the outer wall of the connecting column, and the limiting sliding groove cooperates with the limiting protrusion.

[0017] Preferably, two limiting ball grooves are provided on the outer wall of the connecting column.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The limiter can provide additional buoyancy for the rubber boat. At the same time, the buoys are expanded to both sides to increase the stability of the rubber boat and avoid the rubber boat capsizing during the sea rescue process.

[0022] 2. By using the counterweight ball to lower the center of gravity of the device as a whole, when the rubber boat is hit by strong winds and waves, the rubber boat will tilt and deflect due to the wind and waves. At this time, due to the low center of gravity of the rubber boat, it can quickly return to a balanced state under the action of gravity, achieving rapid self-balancing.

[0023] 3. The displacement handle can be used to drive the limit pin to be pulled out of the limit socket. At this time, the cross connector can be easily separated from the rubber boat to prevent the cross connector from affecting the folding and transportation operation of the rubber boat after deflation. At the same time, the buoyancy stabilization mechanism and the balance mechanism can be easily disassembled from the cross connector, so that the device can be disassembled into small pieces for transportation and transfer.

DETAILED DESCRIPTION

[0032] 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.

[0033] like Figure 1-7 As shown, the present invention has the following specific embodiments.

[0034] Example 1

[0035] A self-balancing rescue device for marine rescue, comprising a rubber boat 1, and further comprising:

[0036] A cross connector 2, wherein connecting holes 204 are provided near the edges of the four corners of the cross connector 2, a plug-in column 101 is fixedly connected to the bottom of the rubber boat 1, the plug-in column 101 and the connecting hole 204 cooperate with each other, and a threaded connecting sleeve 201 is fixedly connected to the bottom of the cross connector 2 near the center;

[0037] The buoyancy stabilization mechanism 4 is connected to the positions on both sides of the cross connection member 2. The buoyancy stabilization mechanism 4 includes a connecting rod 401 and a buoy 402. The buoy 402 is fixedly connected to one end of the connecting rod 401.

[0038] The balancing mechanism 5 includes a connecting sleeve 501 and a connecting column 502. The connecting column 502 is slidably installed in the connecting sleeve 501. A threaded connector 507 is fixedly connected to the upper end of the connecting sleeve 501. The threaded connector 507 is threadedly matched with the threaded connecting sleeve 201. A counterweight ball 503 is fixedly connected to the lower end of the connecting column 502.

[0039] In this embodiment, the cross connector 2 is fixed under the rubber boat 1 by inserting the plug column 101 into the connection hole 204, and the two sides of the cross connector 2 are connected to the buoy 402 through the connecting rod 401. Figure 1As shown, the buoy 402 extends far to both sides of the rubber boat 1. First, the buoy 402 body has a certain buoyancy, which can make up for the reduced carrying capacity of the rubber boat 1 due to the weight increase. Secondly, the buoy 402 expands to both sides, which can increase the stability of the rubber boat 1 and prevent the rubber boat 1 from capsizing during the sea rescue process. Next, the threaded connector 507 is threadedly matched with the threaded connector sleeve 201 to connect the connecting sleeve 501 with the cross connector 2. When the rubber boat 1 is traveling on the sea, the connecting column 502 extends out of the connecting sleeve as much as possible. Inside 501, the counterweight ball 503 connected to its lower end will be kept away from the rubber boat 1 as much as possible. Due to its large deadweight, the counterweight ball 503 will lower the center of gravity of the rubber boat 1 and increase the overall mass of the rubber boat 1. The increased overall mass of the rubber boat 1 will prevent the rubber boat 1 from being affected by small winds and waves due to its inertia, and will be kept in a stable and balanced state as much as possible. When the rubber boat 1 is subject to larger winds and waves, the rubber boat 1 will tilt and deflect due to the winds and waves. At this time, due to the lower center of gravity of the rubber boat 1, it can quickly return to a balanced state under the action of gravity, thereby achieving rapid self-balancing.

[0040] Example 2

[0041] like Figure 3 , 5 As shown, a limiter 3 is fixedly connected to the bottom of the cross connector 2, a limit groove 301 is provided under the limiter 3, a return spring 302 is fixedly connected in the limit groove 301, a limit pin 303 is fixedly connected to the other end of the return spring 302, a limit hole 102 is provided in the plug-in column 101, the limit pin 303 cooperates with the limit hole 102, and a displacement handle 304 is fixedly connected to the return spring 302.

[0042] In this embodiment, the return spring 302 can provide a certain thrust for the limit pin 303. The limit pin 303 will be inserted into the limit socket 102 under the thrust, thereby limiting the plug-in column 101 from being pulled out from the connecting hole 204. The cross connector 2 is fixed under the rubber boat 1. The displacement handle 304 can be used to drive the limit pin 303 to be pulled out of the limit socket 102. At this time, the cross connector 2 can be easily separated from the rubber boat 1, which is convenient for the rubber boat 1 to be deflated and folded for storage and transportation later.

[0043] Example 3

[0044] like Figure 5 , 6 As shown, a T-shaped slide rail 202 is symmetrically fixed to the left and right sides of the cross connector 2, a T-shaped slide groove 403 is opened at the other end of the buoyancy stabilization mechanism 4, the T-shaped slide groove 403 is slidably matched with the T-shaped slide rail 202, a threaded sleeve block 404 is embedded and installed under the connecting rod 401, and a fixing bolt 405 is installed on the inner thread of the threaded sleeve block 404, and the fixing bolt 405 cooperates with the limit card hole 203.

[0045] In this embodiment, the connecting rod 401 is slidably connected to the cross connecting member 2 through the sliding cooperation between the T-shaped slide groove 403 and the T-shaped slide rail 202. After the connecting rod 401 is moved to both sides and unfolded, the fixing bolt 405 is tightened so that its end is inserted into the limit clamping hole 203, and the connecting rod 401 can be fixed under the cross connecting member 2. At the later stage, it is only necessary to unscrew the limit clamping hole 203 to release the fixation of the connecting rod 401, so as to facilitate the separation of the buoyancy stabilization mechanism 4 from the cross connecting member 2.

[0046] Example 4

[0047] like Figure 7 As shown, the inner wall of the connecting sleeve 501 is fixedly connected to a limiting protrusion 504, the outer wall of the connecting column 502 is provided with a limiting slide groove 505, the limiting slide groove 505 and the limiting protrusion 504 cooperate with each other, the outer wall of the connecting column 502 is provided with two limiting ball grooves 506, the outer wall of the connecting sleeve 501 is fixedly connected to a connector 6, the connector 6 is provided with a mounting hole 601, the mounting hole 601 is fixedly connected to an extrusion spring 602, the other end of the extrusion spring 602 is fixedly connected to a limiting clamping ball 603, the limiting clamping ball 603 and the limiting ball groove 506 cooperate with each other.

[0048] In this embodiment, the limiting slide groove 505 cooperates with the limiting protrusion 504 to limit the connecting column 502 to move up and down only inside the connecting sleeve 501. The extrusion spring 602 can provide a certain thrust for the limiting ball 603. The limiting ball 603 will be stuck in the limiting ball groove 506 under the thrust, thereby limiting the connecting column 502 from moving freely, and preventing the counterweight ball 503 from moving up and down due to external force during operation, resulting in a change in the center of gravity position of the rubber boat 1. Two limiting ball grooves 506 are provided, corresponding to the situation where the connecting column 502 is retracted into and extended out of the connecting sleeve 501 respectively.

[0049] The working principle and usage process of the present invention are as follows: when in use, the connecting column 502 needs to be pulled out from the inside of the connecting sleeve 501, so that the counterweight ball 503 is as far away from the rubber boat 1 as possible, and the device can be dropped into the sea for rescue missions. The buoyancy stabilization mechanism 4 extending on both sides can provide additional buoyancy and stability for the rubber boat 1. The counterweight ball 503 has a large weight and will lower the center of gravity of the rubber boat 1. When the rubber boat 1 is subjected to strong winds and waves, the rubber boat 1 will tilt and deflect due to the wind and waves. At this time, since the center of gravity of the rubber boat 1 is relatively low, it can quickly return to a balanced state under the action of gravity, thereby achieving rapid self-balancing.

[0050] 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.
