Description

Technical Field

[0001] This utility model relates to a life-saving device, and more particularly to a flying lifebuoy and shore-side auxiliary equipment. Background Technology

[0002] A life ring is a type of water rescue equipment, usually made of closed-cell foam materials and other materials. It has good buoyancy, water resistance and corrosion resistance, can provide stable support in water, and can withstand a certain amount of pressure and impact. Its outer diameter is no more than 800mm and its inner diameter is no less than 400mm.

[0003] Drowning accidents are frequent, and placing lifebuoys on the shore is a common preventative measure. However, in waters far from the shore, even when lifebuoys are thrown, they often fail to reach the victims in time, leading to tragedies. To address this issue, a method of using drones to carry lifebuoys has been proposed. This method involves attaching the lifebuoy to the bottom of a drone, which is then operated by professionals to deliver it to the desired location. However, because drowning incidents are often sudden, by the time professional rescuers arrive at the scene with specialized drones, the optimal rescue opportunity has often been missed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a flying lifebuoy and shore-side auxiliary equipment to ensure that the flying lifebuoy can be accurately and promptly delivered to the location of the drowning person, so as to achieve the purpose of timely rescue.

[0005] This utility model is achieved through the following technical solution: A flying lifebuoy includes a lifebuoy body with a flight drive mechanism on its outer circumference. The flight drive mechanism drives the lifebuoy body to fly. Inside the lifebuoy body, there is a controller, a wireless receiving module electrically connected to the controller, and a battery. The controller controls the flight drive mechanism. A charging port is provided on one side of the lifebuoy body, through which a charging head is connected to charge the battery.

[0033] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0034] See Figures 1 to 5 This embodiment discloses a flying lifebuoy, including a lifebuoy body 1, which is an annular foam ring. A flight drive mechanism is provided on the outer circumference of the lifebuoy body 1, driving the lifebuoy body 1 to fly. A controller, a wireless receiving module electrically connected to the controller, and a battery are installed inside the lifebuoy body 1. The controller controls the flight drive mechanism. A charging port 2 is provided on one side of the lifebuoy body 1, through which a charging head 3 is connected to charge the battery. A sealing mechanism 4 that can be opened or closed is provided on the lifebuoy body 1, sealing the charging port 2 when closed.

[0035] The flight drive mechanism includes multiple sets of flight drive components 5 spaced apart along the outer circumference of the lifebuoy body 1. In this embodiment, the flight drive mechanism includes four sets of flight drive components 5, which are evenly distributed along the outer circumference of the lifebuoy body 1. Each set of flight drive components 5 includes a protective shell 6, a motor 7, and a propeller 8. The protective shell 6 is fixedly connected to the outer edge of the lifebuoy body 1, and the motor 7 is fixedly connected inside the protective shell 6. The output end of the motor 7 is connected to the propeller 8, and the axis of the propeller 8 is parallel to the axis of the lifebuoy body 1. The motor 7 is controlled by a controller to drive the propeller 8 to rotate, thereby driving the lifebuoy body 1 to move.

[0036] The sealing mechanism 4 includes two fixed seats 10 fixed to the outside of the life ring body 1. Each fixed seat 10 is provided with a guide post 11. The two sides of one end of the sealing plate 13 are respectively provided with sliding seats 12. The two sliding seats 12 of the sealing plate 13 are slidably mounted on the two guide posts 11. The sliding seats 12 of the sealing plate 13 are elastically connected to the fixed seats 10 by a compression spring 14. The guide post 11 is provided with a limiting protrusion ring 15 at the end away from the fixed seat 10. In the natural state, under the elastic force of the compression spring 14, the sealing plate 13 is in the closed state. At this time, the sealing ring on the inner side of the sealing plate 13 seals the charging port 2, which has a waterproof and dustproof effect on the charging port 2 and improves the service life of the life ring.

[0037] This embodiment also discloses a shore-based auxiliary device used in conjunction with the aforementioned flying lifebuoy. The shore-based auxiliary device includes a control box 16, within which is a mounting platform 17 for attaching the flying lifebuoy. A control panel 18 is located on the front of the mounting platform 17. A main controller and a wireless transmission module are located within the inner cavity of the mounting platform 17. The wireless transmission module is wirelessly connected to a wireless receiving module located within the lifebuoy body 1. The control box 16 also contains a battery 20 and a charging device 19. A solar panel 21 is located on the top of the control box 16. The main controller is electrically connected to the battery 20 and the solar panel 21. The charging device 19 is connected to a charging head 3 via wires. The charging head 3 can be plugged into a charging port 2 on one side of the lifebuoy body 1 to charge the battery within the lifebuoy body 1. Both the battery 20 in the shore-based auxiliary device and the battery in the flying lifebuoy are lithium battery packs, designated as lithium battery pack 1 and lithium battery pack 2, respectively.

[0038] The control box 16 has an internal cavity divided into upper and lower cavities by a partition 9. The mounting platform 17 is located in the upper cavity 22, and the battery 20 and charging device 19 are located in the lower cavity 23. The control box 16 includes a box body, and the front of the box body is provided with an openable and closable protective door 24 and a closed door 25. The protective door 24 and the closed door 25 are arranged vertically, corresponding to the upper cavity 22 and the lower cavity 23, respectively.

[0039] The control panel 18 has seven control buttons 26 on its surface, which control movement in six directions: forward, backward, left, right, up, and down, as well as a start control button 26. These seven buttons on the control panel 18 control the various flight drive components 5 of the wireless remote-controlled lifebuoy body 1, causing the lifebuoy to move accordingly, thus enabling it to reach the drowning person more accurately.

[0040] See Figures 6 to 17 The document provides a circuit diagram of the electronic control section of this embodiment. It mainly includes three modules: a solar panel power conversion module, a remote control module for the main controller, and an in-flight lifebuoy control module.

[0041] In the solar panel power conversion module, the charging circuit of the battery 20 uses the LTH7 charging chip. The solar panel 21 converts solar energy into electrical energy through the LTH7 charging chip to charge the two sets of lithium battery packs. Then, the voltage is stabilized at 3.3V through the boost circuit and voltage conversion circuit to power the electrical components in the shore auxiliary equipment and the electrical components in the flying lifebuoy.

[0042] In the remote control module of the main controller, the microcontroller built into the main controller is based on the STC8051U-34K64-QFP48 microcontroller. The main controller is started by controlling the start control button 26. The movement of the flying lifebuoy in six directions (forward, backward, left, right, up, and down) is controlled by six sets of control buttons 26 respectively. Wireless communication is established with the control module inside the flying lifebuoy through the wireless transmission module.

[0043] In the control module inside the flying lifebuoy, the microcontroller built into the flying lifebuoy controller is based on the STC8051U-34K64-QFP48 microcontroller. It communicates wirelessly with the main controller through a wireless receiving module and integrates the signal feedback from the altitude detection circuit and attitude detection circuit to control the motors 7 of the four sets of flight drive components 5 of the flying lifebuoy.

[0044] Upon discovering a drowning person, rescuers open the protective door 24, unplug the charging head 3 from the charging port 2 of the flying lifebuoy, and place the lifebuoy on the ground. Pressing the start control button on the control panel 18 activates the propeller 8 via the wireless remote control motor 7. Rescuers control the direction using four control buttons 26 (forward, backward, left, right) and the altitude using the ascent and descent control buttons 26, guiding the flying lifebuoy towards the drowning person for easy retrieval and rescue. Because the shore-based auxiliary equipment and the flying lifebuoy are located on the shore, and the flying lifebuoy is wirelessly controlled to reach the drowning person, delivery is timely, improving rescue effectiveness and reducing the likelihood of tragedies.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
