Description

Technical Field

[0001] The present invention relates to the technical field of rescue buoys, and specifically relates to a multifunctional marine rescue buoy. Background Art

[0002] Rescue refers to the whole process of obtaining rescue actions when an individual or people encounter disasters or other extraordinary situations. Marine rescue is the search and rescue in the case of disasters at sea. Among them, a marine rescue buoy is a device specially used for marine emergency rescue. It is usually a buoyant floating sign placed in the ocean to provide rescue services and mark the rescue position.

[0003] However, although the existing marine rescue buoys can provide floating support for drowning people, drowning people are often in a panic when in distress. And due to drifting in seawater, the physical strength of drowning people often quickly drains, which may lead to the inability to climb onto the rescue buoy and being washed away by the waves again. At the same time, they can only rely on drowning people to hold the buoy with their hands. During the long waiting process for rescue, they may slip off due to the impact of the waves or physical exhaustion, resulting in falling into the water again.

[0004] In view of the above problems, there is an urgent need for innovative design on the original basis. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional marine rescue buoy to solve the problems raised in the above background art. The technical solution of the present invention provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A multifunctional marine rescue buoy, including a buoy base, a fixed column is installed at the center point of the buoy base, and a rescue platform is slidably installed on the fixed column. A sliding track is opened inside the buoy base. A bottom floating plate is attached to the outer side of the bottom of the buoy base. A protective plate is arranged on the outer side of the upper end of the buoy base. A sliding plate is installed in the outer cavity of the protective plate through a fixed block and a spring. An auxiliary ascending component, the auxiliary ascending component is arranged at the connection between the protective plate and the buoy base, and the auxiliary ascending component is used to push the protective plate upward to assist the drowning person to board the rescue platform. A storage and expansion component, the storage and expansion component is arranged at the bottom of the buoy base, and the storage and expansion component is used for the storage and expansion of the bottom floating plate.

[0007] Preferably, the buoy base is circular in top view, the inside of the buoy base is a cavity, a threaded rod is vertically rotatably installed in the inner wall of the buoy base, and a rotating gear is fixedly installed at the bottom of the threaded rod.

[0008] Preferably, an installation block is threadedly sleeved on the threaded rod, a protective plate is fixed to the outer end of the installation block, the protective plate is arc-shaped in a top view, and the protective plates are arranged at equal angles on the outer side of the buoy base, and a pull rope is connected and installed on a fixed block inside the protective plate.

[0009] Preferably, the auxiliary ascending assembly includes a limiting block elastically installed inside a sliding track through a slider and a spring, and the limiting block is trapezoidal in a side view. A push plate is connected to the inside of the sliding track through a spring. A groove at the top of the push plate is clamped with the limiting block. The limiting block is connected to the fixed block through a pull rope and a rotating shaft, and the rotating shaft is embedded and installed in the sliding track.

[0010] Preferably, a second connecting block is slidably installed inside the sliding track, a sliding rack is elastically installed inside the sliding track through a spring, and the sliding rack meshes with a rotating gear.

[0011] Preferably, a first connecting block is fixedly installed at the bottom of the rescue platform. The first connecting block is connected to the second connecting block through a telescopically connecting rod that rotates around the z-axis. The second connecting block is located between the push plate and the sliding rack.

[0012] Preferably, the storage and expansion assembly includes elastic telescopic rods fixedly arranged at equal angles at the bottom of the rescue platform. The bottom of the elastic telescopic rod is fixedly connected to a moving plate, and the moving plate is slidably installed on a fixed column.

[0013] Preferably, four equally-angled extrusion blocks are slidably installed at the lower end inside the buoy base through a connecting plate, and the surface of the extrusion block is arc-shaped.

[0014] Preferably, the upper end of the extrusion block abuts against the bottom surface of the moving plate, and the extrusion block is fixedly connected to the bottom floating plate through a connecting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When a drowning person swims near the marine rescue buoy, the drowning person can hold the intervals arranged between the protective plates with his hands to stabilize his position. At the same time, step on the sliding plate installed on the protective plate with the soles of the feet, and squeeze the sliding plate to move downward through the body gravity, so that the sliding plate drives the limiting block to pop out of the push plate, so that the push plate, under the action of the spring, pushes the second connecting block inside the sliding track, so that it drives the sliding rack to move towards the outside of the sliding track, so that the whole protective plate moves upward, enabling the drowning person to get closer to the rescue platform, thus reducing the physical strength of climbing. At the same time, the downward movement of the rescue platform pushes the bottom floating plate at the bottom of the buoy base to open, increasing the overall impact resistance and buoyancy of the device; The protection board set at equal angles enables the drowning person to quickly grab the interval between the protection board and the buoy base no matter which side of the rescue buoy they climb from. At the same time, the sliding board set on the protection board can effectively provide support for the drowning person at the bottom of the water. After the limit contact is driven by the sliding board, the protection board moves upward under the meshing action of the mounting block and the threaded rod, thereby providing an upward buoyancy force for the drowning person, so that the drowning person can climb onto the buoy base more labor-savingly and wait for rescue; Furthermore, as the drowning person climbs onto the rescue platform, under the action of gravity, the rescue platform moves downward along the fixed column. At the same time, the elastic telescopic rod connected to the bottom of the rescue platform moves synchronously as the rescue platform moves downward. During the downward movement of the elastic telescopic rod, it synchronously pushes the moving board downward, causing it to push the extrusion block at the bottom outward, so that the bottom floating board at the lower end of the buoy base moves outward, thereby increasing the anti-impact force of the device against sea waves and increasing the comfort of the drowning person inside the rescue buoy.

[0019] Please refer to Figures 1-8 , the present invention provides a technical solution: a multifunctional offshore rescue buoy, including a buoy base 1, a fixed column 2 is installed at the center point of the buoy base 1, and a rescue platform 3 is slidably installed on the fixed column 2. A sliding track 9 is provided inside the buoy base 1. A bottom floating plate 8 is arranged on the outer side of the bottom of the buoy base 1, and a protection plate 6 is arranged on the outer side of the upper end of the buoy base 1.

[0020] As an implementation manner of the present invention, the buoy base 1 is circular in top view, the inside of the buoy base 1 is provided as a cavity, a threaded rod 11 is vertically rotatably installed in the inner wall of the buoy base 1, and a rotating gear 12 is fixedly installed at the bottom of the threaded rod 11; As an implementation manner of the present invention, an installation block 61 is sleeved on the threaded rod 11, a protection plate 6 is fixed at the outer end of the installation block 61, the protection plate 6 is arc-shaped in top view, and the protection plate 6 is arranged on the outer side of the buoy base 1 at equal angles. A pull rope 72 is connected to the fixed block 71 inside the protection plate 6; As an implementation manner of the present invention, the auxiliary ascending component includes a limit block 73 elastically installed in the sliding track 9 through a slider and a spring, and the limit block 73 is trapezoidal in side view. A push plate 74 is connected to the inside of the sliding track 9 through a spring. The top groove of the push plate 74 is engaged with the limit block 73. The limit block 73 is connected to the fixed block 71 through a pull rope 72 and a rotating shaft 75, and the rotating shaft 75 is embedded in the sliding track 9; As an implementation manner of the present invention, a second connecting block 14 is slidably installed in the sliding track 9, and a sliding rack 10 is elastically installed in the sliding track 9 through a spring. The sliding rack 10 is engaged with the rotating gear 12; As an embodiment of the present invention, a connection block 13 is fixedly installed at the bottom of the rescue platform 3, and the connection block 13 is connected to the connection block 2 14 through a rotating telescopic connecting rod 15, and the connection block 2 14 is located between the push plate 74 and the sliding rack 10; When the drowning person finds the rescue buoy, he can first grasp the gap between the protective plate 6 and the buoy base 1. At the same time, the drowning person can step on the sliding plate 7 set on the protective plate 6, and the sliding plate 7 can move downward along the path opened on the protective plate 6 through the gravity of the person. At the same time, during the downward movement of the fixed block 71 installed on the sliding plate 7, the pull rope 72 is pulled to move along the rotating shaft 75, so that the pull rope 72 drives the limit block 73 to pop out from the groove at the upper end of the push plate 74, release the limit on the push plate 74, and then the push plate Under the action of the pressure spring 74, the connecting block 2 14 and the sliding rack 10 are pushed to move toward the outside of the sliding track 9, so that the sliding rack 10 and the rotating gear 12 at the bottom of the threaded rod 11 are meshed, thereby driving the threaded rod 11 to rotate, and the rotating threaded rod 11 and the mounting block 61 are threadedly moved, driving the protective plate 6 to move upward along the surface of the buoy base 1 through the threaded rod 11, providing buoyancy for the drowning person to move upward, thereby better assisting the drowning person to climb onto the rescue platform 3 on the buoy base 1; When the drowning person climbs onto the rescue platform 3, the rescue platform 3 moves downward under the action of gravity, and drives the push plate 74 to move toward the inner end of the sliding track 9 through the telescopic connecting rod 15 until the limit block 73 is re-engaged with the push plate 74, and the sliding rack 10 is reset under the action of the spring, thereby driving the protective plate 6 to reset.

[0021] As an embodiment of the present invention, the storage and expansion assembly includes an elastic telescopic rod 4 fixed at an equal angle to the bottom of the rescue platform 3, the bottom of the elastic telescopic rod 4 is fixedly connected to a movable plate 5, and the movable plate 5 is slidably mounted on the fixed column 2; As an embodiment of the present invention, four extrusion blocks 16 arranged at equal angles are slidably mounted on the inner lower end of the buoy base 1 through a connecting plate 17, and the surface of the extrusion block 16 is in an arc shape; As an embodiment of the present invention, the upper end of the extrusion block 16 abuts against the bottom surface of the movable plate 5 , and the extrusion block 16 is fixedly connected to the bottom floating plate 8 via a connecting plate 17 .

[0022] After the drowning person climbs onto the rescue platform 3, the rescue platform 3 moves downward under the action of gravity. At the same time, the elastic telescopic rod 4 at the bottom of the rescue platform 3 will move downward synchronously with the rescue platform 3. The downward moving elastic telescopic rod 4 will also drive the movable plate 5 to move downward, thereby causing the movable plate 5 to push the bottom extrusion block 16 to deviate outward, driving the bottom floating plate 8 to open, thereby increasing the overall impact resistance and buoyancy of the device.

[0023] Working principle: When a drowning person discovers the buoy, they can steady their body by grasping the space between the protection plate 6 and the buoy base 1. At the same time, the sliding plate 7 provided on the protection plate 6 will provide 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 exerted by the drowning person, it will move downward along the path opened on the protection plate 6 through the fixed block 71. At the same time, the fixed block 71 will drive the pull rope 72 to move. After the pull rope 72 changes direction through the rotating shaft 75, it drives the limit block 73 to pop out from the groove on the push plate 74, releasing the limit on the push plate 74. As a result, the push plate 74 moves outward along the outer side of the sliding track 9 under the action of the compression spring. During the movement, the push plate 74 drives the connecting block two 14 and the sliding rack 10 to move synchronously. During the outward movement, the sliding rack 10 meshes with the rotating gear 12 at the bottom of the threaded rod 11, causing the threaded rod 11 to rotate. The rotating threaded rod 11 performs a threaded movement with the mounting block 61. As a result, the protection plate 6 moves upward along the threaded rod 11 under the action of the mounting block 61, enabling the protection plate 6 and the sliding plate 7 to provide an upward moving support force for the drowning person, reducing the climbing height and the force used by the drowning person, and making it more convenient for the drowning person to board the buoy base 1 and wait for rescue; When the drowning person boards the rescue platform 3, the rescue platform 3 moves downward along the fixed column 2 under the action of gravity. During 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 towards the end of the sliding track 9, thereby driving the push plate 74 to move synchronously, causing the groove at the upper end of the push plate 74 to be re - engaged and limited with the limit block 73. At the same time, the sliding rack 10 also moves back into the sliding track 9 under the action of the tension spring, thereby driving the protection plate 6 to reset; Furthermore, during 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 with the rescue platform 3 after being squeezed, and drives the fixedly connected moving plate 5 to move synchronously, causing the moving plate 5 to push the abutting extrusion block 16, so that the extrusion block 16 pushes the bottom floating plate 8 outward through the connecting plate 17, thereby increasing the overall impact resistance and underwater buoyancy of the device.
