Description

Technical Field

[0001] The utility model belongs to the technical field of water lifesaving equipment, and in particular relates to an unmanned aerial vehicle (UAV) water rescue device. Background Art

[0002] Water rescue refers to the rescue measures taken when people are involved in accidents while engaging in water activities. It is divided into still water rescue and wave rescue. Drowning accidents pose a threat to personal safety during water activities. The current method of deploying lifebuoys is still mainly manual, which is difficult to achieve accurate delivery. With the development of drones, drones have the advantages of low cost, high flight speed, and short preparation time. In response to the need for rapid response in water rescue, drones with fast response and strong maneuverability have been widely used in water rescue.

[0003] Application No. 202321689994.3, a utility model, provides a precision rescue drone thrower for offshore rescue. It includes a lifebuoy, a delivery mechanism fixed to the bottom of the drone, and a rope-collecting mechanism fixed to the shore. The lifebuoy is connected to the delivery mechanism via a first connecting rope, and is thrown in multiple stages. The lifebuoy is connected to the rope-collecting mechanism via a second connecting rope, and the second connecting rope is reeled in to pull the drowning person to the shore. A camera and loudspeaker are also installed below the drone. This solution uses a drone to drag the lifebuoy to the drowning point, and the delivery mechanism releases the lifebuoy in multiple stages, allowing the lifebuoy to land precisely at the drowning point, achieving precise delivery of the lifebuoy. However, its disadvantage is that a rope needs to be reeled in to drag the drowning person ashore, which is limited by the distance from the shore.

[0004] Chinese utility model patent application number 202120013008.7 discloses a flying lifebuoy. The lifebuoy body comprises a shell and a foam float filled within the shell. The body is also equipped with a power supply, a control system, and a flight propulsion system. The power supply powers the control system and the flight propulsion system, which activates and deactivates the flight propulsion system. The flight propulsion system comprises at least two flight components, including electronic speed controllers, brushless motors, and propellers. The shell is provided with equidistant or symmetrical through-holes, each with a diameter greater than the width of the shell ring. The outer edges of the through-holes protrude radially outward from the shell. The control system and flight propulsion system can be used to quickly deliver the flying lifebuoy to a person in the water. The underwater propulsion system then activates to propel the lifebuoy to its destination. In this solution, the flight components are located at the same height as the lifebuoy. If the lifebuoy falls into the water, the entire flight component will also fall into the water. This makes sealing the electronic control system very difficult and expensive, hindering its widespread application.

[0005] Current water drone rescue equipment is mainly based on throwing lifebuoys. Due to the limitations of configuration cost and flexibility of use, it is still not suitable for more water rescue occasions. Utility Model Content

[0006] The purpose of the utility model is to provide a drone water rescue device, which overcomes the shortcomings of the existing technology and adopts an integrated structure of a drone and a life buoy, which can not only use buoyancy to provide support for a person who falls into the water, but also carry the person who falls into the water to the shore; the life buoy is designed in two halves, so that for a person who has lost consciousness in the water, the person who falls into the water can be quickly and conveniently captured and then brought to the shore.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A drone water rescue device comprises a drone and a lifebuoy, wherein the drone and the lifebuoy are connected via a scissor-type unpowered mechanism, wherein the scissor-type unpowered mechanism comprises a connecting rod, a first rocker arm, and a second rocker arm, wherein the upper ends of the two connecting rods are connected to a drone base, and the lower ends of the connecting rods are hinged to the upper ends of the first rocker arm and the second rocker arm, respectively. The middle sections of the first rocker arm and the second rocker arm are connected via a hinge shaft to form a scissor-fork structure, and a return spring is provided below the hinge shaft, wherein the two ends of the return spring are respectively connected to the first rocker arm and the second rocker arm, and the lower ends of the first rocker arm and the second rocker arm are connected to the lifebuoy, and a telescopic guide rod is provided in the return spring; the lifebuoy is a two-part split structure, and the first rocker arm and the second rocker arm are each connected to one part; and the drone is provided with a camera with an intercom function.

[0009] Furthermore, the cross section of the lifebuoy is circular, elliptical or gourd-shaped.

[0010] Furthermore, the lifebuoy is connected to the first swing arm or the second swing arm through a support frame, and at least two connecting fixing belts are provided between the lifebuoy and the support frame.

[0011] Furthermore, the support frame is provided with a handle for a person who falls into the water to grasp.

[0012] Furthermore, the reset spring is a compression spring, with pull rings at both ends connected to the first rocker arm or the second rocker arm.

[0013] Furthermore, the life buoy is a foam life buoy or a cork life buoy, and its exterior is wrapped with canvas or plastic skin.

[0014] Furthermore, the connecting rod, the first rocker arm and the second rocker arm are made of carbon fiber rods or aluminum alloy rods.

[0015] Furthermore, the drone can be replaced by any one of a fixed-wing drone, a rotary-wing drone, an unmanned airship, a parachute-wing drone, and a flapping-wing drone.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1) The drone and lifebuoy are integrated into a structure that acts as a flying lifebuoy. This structure not only allows the drowning person to use its buoyancy to help them climb, but also allows them to be held and moved to the shore without the need for a rope from the shore. When not in use, the lifebuoy serves as the base of the drone, without affecting its storage.

[0018] 2) The scissor-type unpowered mechanism of the utility model does not require external power such as a motor to drive it. It can automatically open or close by using buoyancy and gravity. The structure is greatly simplified and the device is light in weight, which helps to reduce energy consumption and extend the flight time of the UAV.

[0019] 3) The life buoy is designed with two halves. For those who lose consciousness and fall into the water, the opening between the two life buoys can be used to quickly capture the person and then clamp him or her to the shore, which expands the rescue range and has practical significance.

[0027] The technical solutions of the present invention will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] In order to more clearly illustrate the specific implementation methods of the utility model or the technical solutions in the prior art, the specific embodiments required for use in the specific implementation methods or the description of the prior art will be briefly introduced below. Obviously, the specific embodiments described below are some implementation methods of the utility model. For ordinary technicians in this field, other specific embodiments can be obtained based on these specific embodiments without paying creative work.

[0029] The components of the embodiments of the present invention generally described and shown in the specific embodiments herein can be arranged and designed in countless different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the specific embodiments is not intended to limit the scope of the claimed invention, but rather represents only selected embodiments of the present invention.

[0030] See Figure 1-6 , is a schematic structural diagram of an embodiment of a drone water rescue device of the present invention, comprising a drone 1 and a lifebuoy 6, the drone 1 and the lifebuoy 6 are connected by a scissor-type unpowered mechanism, the scissor-type unpowered mechanism comprising a connecting rod 2, a rocker arm 1 7 and a rocker arm 2 8, the upper ends of the two connecting rods 2 are connected to the base of the drone 1, the lower ends of the connecting rods 2 are hinged to the upper ends of the rocker arm 1 7 and the rocker arm 2 8 respectively, the middle sections of the rocker arm 1 7 and the rocker arm 2 8 are connected by a hinge shaft 3 to form a scissor fork structure, a return spring 4 is provided below the hinge shaft 3, the two ends of the return spring 4 are respectively connected to the rocker arm 1 7 and the rocker arm 2 8, the lower ends of the rocker arm 1 7 and the rocker arm 2 8 are connected to the lifebuoy 6, and a telescopic guide rod 12 of a socket structure is provided in the return spring; the lifebuoy 6 is a two-part split structure, the rocker arm 1 7 and the rocker arm 2 8 are each connected to a part, this split structure helps to expand the coverage area and is easier to be caught by people who fall into the water.

[0031] The drone is provided with a camera 13 with an intercom function. The drone operator can quickly lock the target through a controller with a monitoring display screen, and can talk with the drowning person to understand the rescue information, convey the cooperation instructions, and improve the rescue efficiency.

[0032] In this embodiment, the cross-section of the lifebuoy 6 is circular, but may also be elliptical or gourd-shaped. The lifebuoy 6 is connected to the first or second swing arm 7 8 via a support frame 9 . At least two connecting straps 10 are provided between the lifebuoy 6 and the support frame 9 . The support frame 9 enhances the connection strength of the lifebuoy 6 and maintains its position, preventing tilting and rotation that could affect reliable rescue. A handle 11 is provided on the support frame 9 for the drowning person 5 to grasp, facilitating gripping and preventing slipping caused by the smooth surface of the lifebuoy 6 , thereby increasing the success rate of rescue.

[0033] The return spring 4 is a compression spring with pull rings at both ends connected to the rocker arm 1 7 or the rocker arm 2 8. The telescopic guide rod 12 can prevent the compression spring from becoming unstable during the compression process, thereby ensuring its working reliability.

[0034] In the present invention, the life buoy 6 is a foam life buoy or a cork life buoy, and the exterior is wrapped with canvas or plastic skin. The materials of the connecting rod 2, the first pendulum 7 and the second pendulum 8 are carbon fiber rods or aluminum alloy rods, which can further reduce weight.

[0035] The UAV 1 can be replaced by any one of a fixed-wing UAV, a rotary-wing UAV, an unmanned airship, a parachute-wing UAV, and a flapping-wing UAV, and can be selected according to application needs.

[0036] The scissor-type unpowered mechanism eliminates the need for motors, cylinders, or other devices to drive it. When the device is hoisted, the lifebuoy 6, under its own weight, forces the lower ends of the first and second pendulum arms 7 and 8 together, compressing the return spring 4 and placing the device in a retracted position. When the lifebuoy 6 falls into the water, the buoyancy offsets its own weight, causing the return spring 4 to extend outward to its longest position. The lower ends of the first and second pendulum arms 7 and 8 open, allowing the drone 1 to hover in the air. The drone can adjust its direction at any time based on the location of the person in the water until they grab the handle 11, at which point the drone 1 can continue its flight and pull the person to shore. Driven by a drone, the scissor-type unpowered mechanism automatically separates the two halves when they land on the water. A return spring (4) causes them to separate and move forward. If a person falls into the water, the drone can lift them up. Alternatively, if the person grabs the scissor-type mechanism's crossbar, the drone ascends, automatically clamping the person and dragging them to shore. The scissor-type mechanism automatically retracts and extends, requiring no external power.

[0037] During the entire rescue process, the drone 1 remains aloof from the water, thus avoiding malfunctions caused by water ingress into the control device compartment. Conventional sealing structures can handle the task, significantly reducing costs. The entire rescue process is remotely controlled by the operator, providing enhanced maneuverability and a wider rescue coverage area. A camera with intercom functionality enables the drone operator to maintain real-time communication with the drowning victim via a handheld controller, providing psychological support and issuing coordination instructions, significantly improving rescue efficiency.

[0038] In order not to affect the use of the drone in other occasions, the connection between the connecting rod 2 and the drone 1 can be connected by quick-release bolts or pins, so that when the scissor-type unpowered mechanism needs to be removed from the drone, it can be quickly separated.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
