Description

Technical Field

[0001] This utility model relates to the field of water rescue equipment technology, and more specifically, to a flying lifebuoy integrated with SART. Background Technology

[0002] Water rescue equipment is an indispensable safety tool in maritime activities. Its main function is to provide rapid and effective rescue support when people fall into the water, thereby ensuring their safety. Traditional water rescue equipment typically includes life rings and life jackets, which can meet basic rescue needs to a certain extent. However, with the increasing complexity of maritime activities, higher demands are being placed on the performance and functionality of rescue equipment.

[0003] Existing water rescue equipment has several limitations in practical use. Traditional lifebuoys rely mainly on manual throwing or simple mechanical devices for deployment, resulting in low rescue efficiency and difficulty in accurately locating people in the water under complex sea conditions. Furthermore, in nighttime or poor visibility conditions, existing rescue equipment makes it difficult for rescuers to quickly locate those in the water, leading to delays and increased rescue risks. Additionally, existing equipment lacks system coordination capabilities, failing to effectively integrate with modern maritime communication and positioning systems, thus impacting overall rescue efficiency.

[0004] Under special conditions, such as poor visibility, complete darkness, and rough seas, the rescue capabilities of existing water rescue equipment are severely limited. Impaired vision makes it difficult for rescuers to accurately locate those in the water, leading to a lower success rate. Furthermore, existing equipment lacks effective auxiliary positioning functions, failing to provide reliable positioning support for search and rescue personnel in complex environments, further increasing the difficulty and risk of rescues. Therefore, there is a need for water rescue equipment capable of efficiently and accurately locating and rescuing people in the water under all-weather conditions to overcome the shortcomings of existing technology. Utility Model Content

[0005] To address the aforementioned technical issues, a flight lifebuoy integrating SART technology is provided. This flight lifebuoy, by incorporating SART technology into a traditional lifebuoy and combining it with a flight propulsion system and an advanced control system, enables rapid location and rescue of people who have fallen into the water.

[0006] The technical means adopted in this utility model are as follows: An integrated SART (Saving Aid Assist) flying lifebuoy includes: a shell, a battery compartment, a control system, a flight propulsion system, an underwater thruster, and a SART module for life-saving assistance, wherein: The shell is formed by sealing the upper shell and the lower shell together by plastic welding, and a foam float is fixedly installed inside. The battery compartment consists of at least two independent sealed compartments symmetrically arranged inside the shell, with a sealing cover at the compartment opening. Each battery compartment is electrically connected to the control system and the flight propulsion system via wires. The control system is fixed to the front mounting plate of the shell. The control system is electrically connected to the battery compartment, flight propulsion system, underwater thruster and auxiliary rescue SART module through wires, and communicates with the external ground control terminal through a wireless link. The flight propulsion system consists of four sets of identical flight components. Each set of flight components includes an electronic speed controller (ESC), a brushless motor, and a propeller. The shell has four through holes evenly distributed around its circumference. A quadruped is integrally formed in each through hole. A mounting platform is set in the center of the quadruped. The brushless motor is fixed on the mounting platform. The propeller is fastened to the output shaft of the brushless motor. The ESC is fixed inside the shell and is electrically connected to the brushless motor and the control system respectively. The underwater thruster is provided in two sets, symmetrically fixed in the rear part of the shell facing the water surface, and electrically connected to the control system through wires; The SART (Survival Assistance and Rescue) module, embedded in the upper part of the housing, includes a signal processing and control unit, an antenna, a radar receiver, a scanning signal generator, a transmitter, and indicator lights. The antenna serves as both a receiving and transmitting antenna. The radar receiver is used to listen for and receive radar pulse signals in the 9.2-9.5 GHz range. The signal processing and control unit controls the timing of the entire response sequence. When triggered, the scanning signal generator generates a special radio frequency signal. The transmitter amplifies the weak signal generated by the scanning signal generator and transmits it through the antenna.

[0007] Furthermore, the control system includes a main control module, an inertial measurement module, a power management module, an image sensor module, and a GPS module mounted on the mounting plate. The main control module is electrically connected to the inertial measurement module, the power management module, the image sensor module, the GPS module, and the auxiliary rescue module, respectively. The antenna of the image sensor module extends out of the housing through an antenna hole, and the connection between the antenna hole and the antenna is sealed.

[0008] Furthermore, the SART (Survival Assistance and Rescue) module also integrates a warning light, a megaphone, and an infrared detector, all of which are electrically connected to the signal processing and control unit via wires. The infrared detector is used to sense the human body's position and send the signal to the signal processing and control unit. The signal processing and control unit then activates the flight propulsion system or underwater thruster through the control system to approach the target.

[0009] Furthermore, a switch is provided on the outside of the housing, which is connected in series in the power supply circuit between the battery compartment and the control system to control the on / off state of the entire circuit.

[0010] Furthermore, the housing is also provided with an observation chamber, in which a waterproof gimbal camera is fixed, and the waterproof gimbal camera is electrically connected to the control system via wires.

[0011] Furthermore, the shell edge is provided with at least one rope-tying platform away from the through hole, and each rope-tying platform is provided with a rope-tying hole for fixing the rescue cable.

[0012] Furthermore, protective fences are fixed at both the upper and lower openings of the through hole.

[0013] Furthermore, the battery compartment is equipped with a waterproof cover, and the battery compartment contains 3-6 series-connected lithium batteries. The connecting wires between the battery compartment and the electronic speed controller, control system and underwater thruster all pass through the sealed joints into the shell to ensure the watertightness of the shell.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0021] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0024] like Figure 1-3 As shown, this utility model provides a flight lifebuoy with integrated SART, including: a shell 1, a battery compartment 5, a control system 14, a flight propulsion system, an underwater thruster 17, and an auxiliary rescue SART module, wherein: The shell 1 is formed by sealing the upper shell 8 and the lower shell 9 together with plastic welding, and a foam float 15 is fixedly installed inside. In this embodiment, the shell 1 is a plastic shell, consisting of an upper shell and a lower shell. During production, the connecting parts are joined together using a plastic welding process. Before welding, the internal parts need to be fixed and installed first.

[0025] The battery compartment 5 consists of at least two independent sealed compartments symmetrically arranged inside the shell 1. Each compartment opening is equipped with a sealing cover. Each battery compartment 5 is electrically connected to the control system 14 and the flight propulsion system via wires. The control system 14 is fixed to the front mounting plate of the housing 1. The control system 14 is electrically connected to the battery compartment 5, the flight propulsion system, the underwater thruster 17 and the auxiliary rescue SART module through wires, and communicates with the external ground control terminal through a wireless link. The flight propulsion system consists of four sets of identical flight components. Each set of flight components includes an electronic speed controller (ESC) 13, a brushless motor 12, and a propeller 11. The housing 1 has four through holes 10 evenly distributed around its circumference. Each through hole 10 contains an integrally formed quadruped 16. A mounting platform is provided in the center of the quadruped 16. The brushless motor 12 is fixed on the mounting platform, and the propeller 11 is fastened to the output shaft of the brushless motor 12. The ESC 13 is fixed inside the housing 1 and is electrically connected to the brushless motor 12 and the control system 14, respectively. In this embodiment, because the propeller is large, it needs to protrude outward. Therefore, the housing of the flight lifebuoy is not a traditional ring shape.

[0026] The underwater thrusters 17 are provided in two sets, symmetrically fixed to the rear of the housing 1 on the side facing the water surface, and electrically connected to the control system 14 through wires. In this embodiment, the function of the underwater thrusters 17 is to bring the person who has fallen into the water to the shore, reducing the physical exertion of the person. When the flying lifebuoy cannot fly directly to the destination, it can swim to the destination on the water surface in conjunction with the waterproof gimbal camera and infrared detector.

[0027] The SART (Survival Assistance and Rescue) module, embedded in the upper part of the housing 1, includes a signal processing and control unit, an antenna 18, a radar receiver 19, a scanning signal generator 20, a transmitter 21, and an indicator light 22. The antenna 18 serves as both a receiving and transmitting antenna. The radar receiver 19 is used to listen for and receive radar pulse signals in the 9.2-9.5 GHz range. The signal processing and control unit controls the timing of the entire response sequence. When triggered, the scanning signal generator 20 generates a special radio frequency signal. The transmitter 21 amplifies the weak signal generated by the scanning signal generator 20 and transmits it through the antenna 18. In this embodiment, the SART module is activated by "interrogation," meaning that once the person in distress activates the SART module, it enters a standby state. Once the 9GHz marine radar (X-band radar) on a search and rescue vessel or aircraft illuminates the module, the SART (Survival Assistance Module) will be triggered by the radar wave, immediately emitting a special, powerful response signal. This response signal will be received by the search and rescue unit's radar and displayed on its radar screen as a series of very bright, conspicuous dots (usually 12), extending outwards from the actual location of the SART module along the radar's radiation direction, thus assisting in the rescue. In other aspects, a megaphone can be used for the drowning person to call for help. An infrared detector can emit infrared light to detect the location and coordinates of the drowning person and convert the wave signal into an electrical signal, feeding it back to the control system, allowing the flying lifebuoy to fly towards the person's location. In this embodiment, antenna 18 typically uses a blade antenna or waveguide slot antenna, serving as both a receiving antenna (receiving 9GHz radar scan pulses) and a transmitting antenna (transmitting 9GHz response signals). The antenna's design gives it omnidirectional or near-omnidirectional characteristics, ensuring it can be triggered regardless of the direction from which the search and rescue radar scans. The radar receiver (RX) 19 is a tuning circuit specifically designed to detect and receive radar pulse signals in the 9.2-9.5 GHz (X-band) frequency range, filtering out interference signals at other frequencies. The signal processing and control unit is the logical center of the Auxiliary Rescue SART module. This unit is activated once the receiver detects a valid radar pulse. It controls the timing of the entire response sequence, ensuring that the Auxiliary Rescue SART module transmits a frequency sweep signal for up to 100 milliseconds as specified. The scanning signal generator 20 is the core technology of the Auxiliary Rescue SART module. When triggered, it generates a special radio frequency signal that rapidly sweeps the frequency within the 9 GHz band (e.g., from 9.2 GHz to 9.5 GHz), resulting in a unique display effect of 12 bright spots on the search and rescue radar screen. The transmitter 21 amplifies the weak signal generated by the frequency sweep signal generator 20 into a powerful pulse signal (with extremely high peak power), which is then transmitted through the antenna 18. This ensures clear reception by the search and rescue radar at long distances.

[0028] In a preferred embodiment of this utility model, the control system 14 includes a main control module, an inertial measurement module, a power management module, an image sensor module, and a GPS module mounted on a mounting plate. The main control module is electrically connected to the inertial measurement module, the power management module, the image sensor module, the GPS module, and the auxiliary rescue module. The antenna of the image sensor module extends out of the housing 1 through an antenna hole, and the connection between the antenna hole and the antenna is sealed.

[0029] In a preferred embodiment of this invention, the SART (Survival Assistance and Rescue) module also integrates a warning light, a megaphone, and an infrared detector, all electrically connected to a signal processing and control unit via wires. The infrared detector senses the location of the person in the water and sends a signal to the signal processing and control unit. The signal processing and control unit then activates the flight propulsion system or underwater thruster 17 via the control system 14 to approach the target. In this embodiment, the megaphone can be used for the drowning person to call for help, enabling a voice call function; the infrared detector emits infrared rays to detect the location and coordinates of the drowning person, converting the wave signal into an electrical signal and feeding it back to the control system, which can then activate the flight propulsion system to approach the person based on their location. When in use, pressing the silver-white switch will activate the SART (Survival Assistance Module). During operation, the pulse wave of the search and rescue radar (9GHz) scans the antenna 18 of the SART module. The signal processing and control unit then commands the frequency sweep signal generator 20 to generate a special signal, which is amplified by the transmitter 21 and transmitted by the antenna 18. Simultaneously, the indicator light 22 begins to flash, informing the person in distress that the device has been triggered. The internal radar receiver 19 detects the signal and wakes up the signal processing and control unit. The frequency sweep signal is received by the radar receiver 19, processed, and displayed as 12 bright spots on the radar receiver 19 screen, thus achieving the purpose of assisting in rescue.

[0030] In a specific implementation, as a preferred embodiment of this utility model, a switch 2 is provided on the outside of the housing 1. The switch 2 is connected in series in the power supply circuit between the battery compartment 5 and the control system 14 to control the on / off state of the entire circuit.

[0031] In a preferred embodiment of this invention, the housing 1 further includes an observation chamber 7, the front of which is a transparent outer cover coated with a hydrophobic coating. A waterproof gimbal camera (either a visible light camera or an infrared dual-light camera) is fixed inside the observation chamber 7. The waterproof gimbal camera is electrically connected to the control system 14 via wires. In this embodiment, the waterproof gimbal camera can adjust its shooting angle by rotating the gimbal, allowing the operator to observe the state of the person in the water and accurately position the flying lifebuoy next to them. The infrared dual-light camera can help the operator quickly identify the location of the person in the water in a field environment.

[0032] In a specific implementation, as a preferred embodiment of this utility model, at least one tethering platform 4 is provided on the edge of the shell 1 away from the through hole 10, and each tethering platform 4 is provided with a tethering hole 6 for fixing the lifeline, so as to facilitate the fixing of the life ring on the ship.

[0033] In a specific implementation, as a preferred embodiment of this utility model, protective fences 3 are fixed at both the upper and lower openings of the through hole 10 to prevent accidental injury to those who fall into the water during startup.

[0034] In a specific implementation, as a preferred embodiment of this utility model, the battery compartment 5 is provided with a waterproof cover, and the battery compartment 5 contains 3-6 series-connected lithium batteries (the number is selected according to the actual use scenario). The connecting wires between the battery compartment 5 and the ESC 13, the control system 14 and the underwater thruster 17 all pass through the sealed joints and enter the interior of the shell 1 to ensure the watertightness of the shell 1.

[0035] In use, first turn on the switch on the casing. The ground control unit sends a remote control signal to the control system. The control system 14 activates the flight propulsion system, and the flying lifebuoy takes off and flies to the designated location according to the remote control instructions. If the flight environment is limited or the target needs to be searched after approaching the destination, the flying lifebuoy can land and float on the water. At this time, the underwater thruster is activated to propel the device to the destination. During the search and rescue process, the waterproof gimbal camera can expand the field of view by rotating the gimbal, and the SART (Search and Rescue Auxiliary) module starts working, so that the location of the person in the water can be marked on the radar, achieving the purpose of assisted positioning.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
