Description

Technical Field

[0001] The invention relates to the technical field of emergency rescue equipment, and in particular to a fast-falling lifesaving device based on gyroscopic effect. Background Art

[0002] In emergency rescue operations in oceans, rivers and other waters, lifebuoys carried by drones are often used to reach the destination. The drone will throw the lifebuoy near the drowning person to achieve the purpose of rescue. However, after the drone drops the lifebuoy, the lifebuoy slowly descends until it falls to the water surface. During the falling process of the lifebuoy, factors such as wind force will affect the attitude stability of the lifebuoy. Coupled with the adverse effect of positioning accuracy, it may be difficult to accurately drop the lifebuoy and fail to accurately reach the drowning person, thus causing the failure of the rescue operation. Summary of the invention

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in conjunction with the accompanying drawings. The following is a preferred embodiment of the present invention, which is intended to provide a basic understanding of the present invention, but is not intended to confirm the key or decisive elements of the present invention or to limit the scope of protection.

[0028] It should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Please refer to Figure 1 The embodiment of the present invention provides a fast-falling lifesaving device based on gyroscopic effect, which is applied to a drone. The fast-falling lifesaving device based on gyroscopic effect can be launched toward a target position through a launching device on the drone. The fast-falling lifesaving device based on gyroscopic effect mainly includes a lifebuoy 1, a bracket 2, two permanent magnets 3 and a rotating mechanism 4.

[0030] The life buoy 1 is generally a standard life buoy 1 in a circular shape, and can float horizontally on water.

[0031] The lifebuoy 1 is installed at the bottom of the bracket 2. As in this embodiment, a clamp 201 is provided at the bottom of the bracket 2, and the clamp 201 clamps the lifebuoy 1 tightly to fix the lifebuoy 1 to the bracket 2. Generally, the lifebuoy 1 is vertically arranged, and the bracket 2 is connected to the top of the lifebuoy 1.

[0032] Please refer to Figure 2 and3 The two permanent magnets 3 are mounted on the bracket 2 and arranged opposite to each other up and down. The two permanent magnets are located above the lifebuoy 1, and the opposite ends of the two permanent magnets 3 have opposite magnetic properties, that is, the opposite ends of the two permanent magnets 3 are N poles and S poles respectively, so that a stable external permanent magnetic field can be formed.

[0033] Please refer to Figure 4 The rotating mechanism 4 includes a shell 401, a rotating shaft 402 and a rotor coil 403. The rotating shaft 402 can be rotatably installed on the bracket 2. The shell 401 is sleeved on the rotating shaft 402. The rotor coil 403 is arranged in the shell 401 and sleeved on the rotating shaft 402. The rotor coil 403 is located between the two permanent magnets 3. The shell 401 is provided with a plurality of water inlet holes 405.

[0034] The upper part of the bracket 2 is provided with a rectangular frame 202, and the rotating shaft 402 is arranged horizontally and rotatably penetrates the opposite sides of the rectangular frame 202 at both ends. The two permanent magnets are arranged symmetrically with respect to the rotating shaft 402 and have opposite magnetic properties, and the two permanent magnets are fixedly mounted on the upper surface and the lower surface of the inner wall of the rectangular frame 202 respectively.

[0035] The two ends of the rotating shaft 402 respectively penetrate the two sides of the bracket 2, and brushes 404 are provided at both ends of the rotating shaft 402, and the brushes 404 are connected to the rotor coil 403 through wires. The rotor coil 403 is powered by the two brushes 404, and the rotation of the brushes 404 can cause the direction of the DC current to change periodically, forming a periodic electromagnetic field around the rotor coil 403. The rotor coil 403 accelerates the rotation under the combined action of the periodic electromagnetic field and the external permanent magnetic field, and drives the housing 401 to rotate. In order to make the housing 401 rotate stably, the housing 401 is a hollow cylinder, and the housing 401 is coaxially arranged with the rotating shaft 402.

[0036] After the life buoy 1 falls into the water, the end closer to the rotating mechanism 4 is heavier and enters the water first, and the water quickly fills the shell 401 through the water inlet holes 405 to achieve rapid deceleration. In order to make it easier and faster for water to penetrate the shell 401, the water inlet holes 405 are long holes arranged along the axial direction of the shell 401, and each of the water inlet holes 405 is arranged around the shell 401 at intervals.

[0037] In some embodiments, in order to make it easier for the lifebuoy 1 to maintain a vertical state when falling, the fast-falling lifesaving device based on the gyroscopic effect is symmetrically arranged relative to the vertical center plane of the lifebuoy 1, that is, the bracket 2, the two permanent magnets 3 and the rotating mechanism 4 are all symmetrical relative to the vertical center plane of the lifebuoy 1.

[0038] In some embodiments, considering that the rapid-falling life-saving device based on the gyroscopic effect is installed on a drone, spring plungers 203 are provided on both outer sides of the bracket 2, and the drone is connected through the spring plungers 203. Before the ejection device is started, the rapid-falling life-saving device based on the gyroscopic effect is connected to the drone through the spring plungers 203, and after the ejection device is started, the spring plungers 203 are separated from the drone.

[0039] A fast-falling lifesaving device based on gyroscopic effect of the present invention is installed at the bottom of a drone. During emergency rescue, the fast-falling lifesaving device based on gyroscopic effect is first transported to a target position above a drowning person by a drone. Then, direct current is transmitted by a battery carried by the drone, and the rotor coil 403 rotates. The rotation of the rotor coil 403 drives the rotating shaft 402 to rotate. The brush 404 changes the direction of the current, thereby keeping the direction of the electromagnetic force on the rotor coil 403 unchanged. The rotor coil 403 can accelerate the rotation in a fixed direction, so that the rotating mechanism 4 completes energy storage. Afterwards, the fast-falling lifesaving device based on gyroscopic effect is ejected downward by an ejection device on the drone, and the direct current input to the rotor coil 403 is disconnected. The fast-falling lifesaving device based on the gyroscopic effect falls, and the high-speed rotating mechanism 4 has a large angular momentum. According to the gyroscopic effect, it can maintain its posture in the air and fall in a vertical posture until it falls to the water surface near the drowning person; finally, after the lifebuoy 1 falls into the water, the end close to the rotating mechanism 4 is heavier and will enter the water first, and the water will quickly fill the shell 401 through the water inlet hole 405 to achieve rapid deceleration, and the decelerating rotating mechanism 4 cannot maintain the lifebuoy 1 vertical, and finally the lifebuoy 1 floats horizontally on the water. Since the water resistance is much greater than the air resistance, the rotating mechanism 4 can stop in a short time when the lifebuoy 1 reaches the water surface. At this time, the lifebuoy 1 will no longer remain upright due to the angular momentum of the rotor coil 403, and the fallen lifebuoy 1 is convenient for the drowning person to grasp, thereby completing the lifesaving.
