[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To address the issue that most existing lifebuoys are stationary and require manual throwing to the drowning victim in case of a drowning incident, which can lead to delays and missed opportunities for timely rescue if the victim is too far away; please refer to... Figure 1-4 The present invention provides the following solution:

[0019] An automatic lifebuoy throwing device includes a thrower body 1 and a lifebuoy body 101. The thrower body 1 has a storage compartment inside, and the lifebuoy body 101 is installed in the storage compartment. A locking pin box 4 is installed on the top of the thrower body 1 by screws. A stepper motor 403 is installed inside the locking pin box 4. The stepper motor 403 is electrically connected to a drive box 2 through a circuit. The drive box 2 is connected to a start button 3 through a circuit.

[0020] In this embodiment, pressing the button turns on the power, and the stepper motor 403 is controlled to run through the drive box 2. When the stepper motor 403 rotates, the eccentric cam 404 will rotate at the same time, driving the pull rod 102 to move up and down reciprocally. When the pull rod 102 moves down, it repeatedly presses up the hook 1031. The stop bar 1032 will open under the weight of the lifebuoy, and the lifebuoy will be released. The pull rod 102 and the hook 1031 are respectively equipped with springs and tension springs for reset. The stepper motor 403 is controlled by the driver program to return to the locking position, and then the power is automatically turned off. The electric lifebuoy release device can be reused without replacing any parts. After the lifebuoy is released, it can be manually put back into the release box and the stop bar can be manually moved back to the standby state for reuse.

[0021] An eccentric cam 404 is mounted on the front end of the stepper motor 403. The eccentric cam 404 is rotated by the stepper motor 403. The bottom of the eccentric cam 404 is connected to one end of the pull rod 102 by a spring. A manual pin 401 is mounted on the top of the locking pin box 4. The manual pin 401 extends inward into the interior of the eccentric cam 404, and a safety pin 402 is mounted in the middle section of the manual pin 401. A locking hook assembly 103 is mounted on the other end of the pull rod 102. The locking hook assembly 103 includes a hook 1031 and a stop bar 1032. The pull rod 102 is rotatably connected to the hook 1031. One end of the stop bar 1032 is connected to the hook 1031 through a slot, and the other end of the stop bar 1032 is rotatably connected to the thrower body 1.

[0022] In this embodiment, the unlocking of the locking hook assembly 103 allows the lifebuoy body 101 to be free from any mechanical constraints. Under the combined action of the enormous kinetic energy released by the spring, the lifebuoy's own buoyancy, and the ejection mechanism, the lifebuoy body 101 is automatically and powerfully launched from the storage compartment of the thrower body 1 along a preset track at an extremely high initial velocity, flying towards the water area where the person in the water is located. After a rescue operation is completed, the staff can manually retrieve the lifebuoy, reinstall it in the storage compartment, pull the lever 102 to make the locking hook assembly 103 hook the lifebuoy again, and use the manual pin 401 and safety pin 402 to relock the eccentric cam 404 and the entire mechanism, so that the spring is in the energy storage state again, and the device returns to the standby state, ready to perform the next rescue mission.
