TECHNICAL FIELD

[0001] The present application relates to the technical field of rescue buoys, in particular to a multifunctional offshore rescue buoy. BACKGROUND

[0002] Rescue refers to the entire process of obtaining rescue action when individuals or people encounter disasters or other extraordinary situations, and offshore rescue is the search and rescue in the case of disaster at sea, wherein the offshore rescue buoy is a device specially used for emergency rescue at sea, which is usually a floating buoy with buoyancy, placed in the sea to provide rescue services and mark the rescue location.

[0003] However, although the existing offshore rescue buoy has the function of providing support for the floating of the drowning person, the drowning person is often in a panic when in distress, and due to the drifting in the sea, the drowning person often loses physical strength quickly, which may cause the drowning person to be unable to climb onto the rescue buoy and be swept away by the waves again. At the same time, the drowning person can only rely on the hand to hold the buoy, and in the process of waiting for rescue for a long time, the phenomenon of slipping may occur due to the impact of the waves or the lack of physical strength, resulting in falling into the water again.

[0004] In view of the above problems, it is urgent to make innovative design on the basis of the original. SUMMARY

[0012] Preferably, a connecting block two is slidably mounted in the sliding rail, and the sliding rail is elastically mounted with a sliding rack through a spring.

[0013] Preferably, a connecting block one is fixedly mounted at the bottom of the rescue platform, the connecting block one is connected with the connecting block two through a z-rotating telescopic connecting rod, and the connecting block two is located between the pushing plate and the sliding rack.

[0014] Preferably, the accommodation and opening assembly comprises an elastic telescopic rod fixedly arranged at equal angles at the bottom of the rescue platform, and a moving plate is fixedly connected at the bottom of the elastic telescopic rod and slidably mounted on the fixed stand.

[0016] Preferably, the upper end of the extrusion block and the bottom surface of the moving plate are mutually abutted, and the extrusion block is fixedly connected with the bottom buoy plate through the connecting plate.

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] When the drowning person swims to the vicinity of the sea rescue buoy, the drowning person can hold the interval between the guard plates with his hands to stabilize his position, and at the same time, the soles of his feet step on the sliding plates installed on the guard plates, and through the body gravity, the sliding plates are squeezed to move downward, so that the sliding plates drive the limiting blocks to pop out from the push plates, so that the push plates push the connecting blocks two in the sliding rail under the action of the spring, so that the sliding rack moves to the outside of the sliding rail, so that the guard plates as a whole move upward, so that the drowning person can be closer to the rescue platform, thereby reducing the physical strength of climbing, and at the same time, the bottom floating plate at the bottom of the buoy base is pushed open by the downward movement of the rescue platform, thereby increasing the overall impact resistance and buoyancy of the device;

[0037] As an embodiment of the present application, a connecting block two 14 is slidingly mounted in the inside of the sliding rail 9, and the inside of the sliding rail 9 is elastically mounted with a sliding rack 10 through a spring, and the sliding rack 10 is meshed with a rotating gear 12;

[0038] As an embodiment of the present application, the bottom of the rescue platform 3 is fixedly mounted with a connecting block one 13, the connecting block one 13 is connected with the connecting block two 14 through a rotating telescopic connecting rod 15, and the connecting block two 14 is located between the push plate 74 and the sliding rack 10;

[0039] When the drowning person finds the rescue buoy, the person can first hold the interval between the protective plate 6 and the buoy base 1, and the bottom of the feet of the person can be placed on the sliding plate 7 arranged on the protective plate 6, the sliding plate 7 is moved downward along the path arranged on the protective plate 6 under the gravity of the person, and in the process of the downward movement of the fixed block 71 mounted on the sliding plate 7, the pull rope 72 is moved along the rotating shaft 75, so that the pull rope 72 drives the limiting block 73 to pop out from the upper groove of the push plate 74, the limiting of the push plate 74 is released, and then the push plate 74 drives the connecting block two 14 and the sliding rack 10 to move outward of the sliding rail 9 under the action of the pressure spring, so that the sliding rack 10 is meshed with the rotating gear 12 at the bottom of the threaded rod 11 to move, and then the threaded rod 11 is rotated, the threaded rod 11 is in threaded motion with the mounting block 61, and the protective plate 6 is moved upward along the surface of the buoy base 1 through the threaded rod 11, so as to provide buoyancy for the upward movement of the drowning person, thereby better assisting the drowning person to climb onto the rescue platform 3 on the buoy base 1;

[0040] When the drowning person climbs onto the rescue platform 3, the rescue platform 3 is moved downward under the action of gravity, and the push plate 74 is moved toward the inner end of the sliding rail 9 through the telescopic connecting rod 15 again, until the limiting block 73 is clamped with the push plate 74 again, and the sliding rack 10 is reset under the action of the spring, thereby resetting the protective plate 6.

[0044] After the drowning person climbs onto the rescue platform 3, the rescue platform 3 moves downward under the action of gravity, and the elastic telescopic rods 4 at the back bottom of the rescue platform 3 move downward synchronously with the rescue platform 3, the downward moving elastic telescopic rods 4 drive the moving plate 5 to move downward, and further drive the extrusion block 16 at the bottom to deviate outward, drive the opening of the bottom floating plate 8, and increase the overall impact resistance and buoyancy of the device.

[0045] Working principle: when the drowning person finds the buoy, the drowning person can hold the interval between the guard plate 6 and the buoy base 1 to stabilize the body, and the sliding plate 7 arranged on the guard plate 6 provides a foothold for the drowning person, further improving the support stability of the drowning person. When the sliding plate 7 is subjected to the gravity applied by the drowning person, the fixed block 71 will move downward along the path opened on the guard plate 6, and the fixed block 71 will drive the pull rope 72 to move, the pull rope 72 changes direction through the rotating shaft 75, drives the limiting block 73 to pop out from the groove on the push plate 74, releases the limiting of the push plate 74, and further makes the push plate 74 move outward along the sliding rail 9 under the action of the pressure spring, and in the moving process, the connecting block two 14 and the sliding rack 10 move synchronously, the sliding rack 10 and the rotating gear 12 at the bottom of the threaded rod 11 move in meshing motion in the outward moving process, the threaded rod 11 rotates, the rotating threaded rod 11 and the mounting block 61 move in screw threads, and further make the guard plate 6 move upward along the threaded rod 11 under the action of the mounting block 61, so that the guard plate 6 and the sliding plate 7 provide upward moving support force for the drowning person, reduce the height and the force used by the drowning person in climbing, and make it more convenient for the drowning person to climb onto the buoy base 1 to wait for rescue;

[0046] When the drowning person gets on the rescue platform 3, the rescue platform 3 moves downward along the fixed column 2 under the action of gravity, in the process of the downward movement of the rescue platform 3, the telescopic connecting rod 15 rotatably installed on the connecting block one 13 at the bottom of the rescue platform 3 pushes the connecting block two 14 to move towards the tail end of the sliding rail 9, thereby driving the synchronous movement of the push plate 74, so that the groove at the upper end of the push plate 74 re-couples with the limiting block 73 for limiting, at the same time, the sliding rack 10 also moves back to the inside of the sliding rail 9 under the action of the tension spring, thereby driving the protective plate 6 to reset;

[0047] Further, in the process of the downward movement of the rescue platform 3, the elastic telescopic rod 4 at the bottom of the rescue platform 3 also moves downward synchronously after being extruded, and drives the synchronous movement of the fixedly connected moving plate 5, so that the moving plate 5 pushes the extrusion block 16, thereby making the extrusion block 16 push the bottom floating plate 8 outward through the connecting plate 17, so as to increase the overall anti-impact strength and underwater buoyancy of the device.
