Description

Technical Field

[0001] This invention belongs to the field of rescue equipment technology, specifically relating to a multi-powered flight rescue device. Background Technology

[0002] Traditional rescue equipment, such as lifeboats and life rafts, suffers from drawbacks such as large size and weight, inconvenient storage and transportation, and difficulty in daily maintenance. While drones have emerged in recent years to drop life rings, solving the rapid response problem to some extent, they still have limitations, including poor throwing accuracy and inability to actively rescue unconscious individuals in the water.

[0003] While there have been various attempts at flying rescue devices in the prior art, such as the flying lifebuoy for water rescue described in Chinese patent application number CN202211163055.5, which, by activating the rotor module, allows the lifebuoy to land near the person in the water, and then activates the first and second form-changing mechanisms to turn the rotor module, changing the lifebuoy from flight mode to propulsion mode, enabling it to be accurately deployed to the person in the water for rescue, some shortcomings still exist in practical use:

[0004] First, in order to ensure the stability of the rescued person and prevent them from falling off the rescue device, it is usually necessary to have both arms on the life ring. However, when adjusting the course of the rescue device, one or even two arms are needed to turn the handwheel, which can easily cause the rescued person to slip off the rescue device and fall into the water, affecting the safety and stability of the rescue. In addition, it is difficult to carry out when physical strength is insufficient or the water temperature is low.

[0005] Secondly, the lack of a surface-triggered autonomous power mode switching mechanism means that when the device contacts the water, it cannot automatically switch from flight mode to propulsion mode or other suitable power modes for water rescue. This lack of an autonomous power mode switching mechanism requires rescuers to manually switch modes or have them remotely controlled by external personnel. This not only increases the complexity of the operation but may also affect rescue efficiency due to delayed response or operational errors, and even threaten the lives of those who have fallen into the water. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-powered flight rescue device that can quickly fly to and automatically switch to water surface navigation. Through dual control and a safe grip design, it significantly improves rescue efficiency and personnel safety.

[0007] The specific technical solution adopted by this invention is as follows:

[0008] A multi-powered flight rescue device includes a shell, with power mechanisms located at each of the four corners of the shell, and a power supply unit, an image acquisition unit, and a circuit board installed inside the shell.

[0009] The power switching mechanism is located at one end of the housing and is used to switch the power mechanism between air flight mode and surface navigation mode.

[0010] Control components, both of which are mounted on the housing;

[0011] The gas delivery mechanism consists of two separate gas delivery mechanisms mounted on two control components.

[0012] The braking mechanism consists of two braking mechanisms, each located on a power mechanism that is far from the image acquisition unit.

[0013] The power switching mechanism includes a drive unit located at the lower end of the housing. The housing has a limit part inside its cavity, a moving part inside the housing, a transmission part inside the moving part, and an adjustment part on the housing.

[0014] In a preferred embodiment, the power mechanism includes a frame, with four frames located at the four corners of the housing. Two round rods are fixedly connected to the frame. The round rods on the two frames closest to the image acquisition unit are fixedly connected to the housing, while the round rods on the other two frames are rotatably connected to the housing. A power motor is fixedly mounted on the frame using a bracket, and blades are fixedly mounted on the output shaft of the power motor.

[0015] In a preferred embodiment, the drive unit includes a hollow cylinder threaded to the bottom surface of the housing. An annular groove is formed on the hollow cylinder, and a sealing ring is slidably connected within the annular groove. A first spring is fixedly connected between the annular groove and the sealing ring. A partition is fixedly connected inside the hollow cylinder, dividing it into an upper chamber and a lower chamber. An expansion body is placed in the upper chamber of the hollow cylinder. A water inlet is formed at the lower end of the hollow cylinder. A float is placed in the lower chamber of the hollow cylinder, and the float is fixedly connected to the sealing ring via a support rod. A lifting rod is piston-type inserted at the lower end of the housing, located at the hollow cylinder. A trapezoidal plate is fixedly connected to the upper end of the lifting rod, and a circular plate is fixedly connected to the lower end of the lifting rod.

[0016] In a preferred embodiment, the limiting part includes a guide rail, which is fixedly connected to the bottom surface of the inner cavity of the housing. A locking block is slidably connected to the guide rail, one end of which is trapezoidal, and a second spring is sleeved on one end of the guide rail.

[0017] In a preferred embodiment, the movable part includes a slide groove, which is formed on the bottom surface of the inner cavity of the housing. A movable block is slidably connected in the slide groove. A first rack is fixedly connected to the upper end of the movable block, and a second rack is fixedly connected to the side of the movable block. A locking groove is formed on the movable block, and a return spring is fixedly connected between the slide groove and the movable block.

[0018] In a preferred embodiment, the transmission unit includes a transmission rod, which is fixedly connected between two round rods that are rotatably connected to the housing, and a first gear is fixedly mounted on the transmission rod.

[0019] In a preferred embodiment, the adjusting part includes an adjusting rod, which is rotatably connected to the housing via a sealed bearing. A second gear is fixedly mounted on the lower end of the adjusting rod, and an adjusting knob is fixedly connected to the upper end of the adjusting rod.

[0020] In a preferred embodiment, the control component includes a hollow shell, which is fixedly connected to a cavity within a housing. A piston plate is slidably connected inside the hollow shell. A third spring is fixedly connected to one side of the piston plate, and the other end of the third spring is fixedly connected to the inner wall of the hollow shell. An electromagnet is fixedly installed on the top surface of the inner cavity of the hollow shell. A handle is fixedly connected to the top surface of the housing. A control rod is slidably connected to the handle. A traction rope is fixedly connected to the control rod, and the other end of the traction rope passes through the hollow shell and is fixedly connected to the piston plate.

[0021] In a preferred embodiment, the gas delivery mechanism includes a first gas delivery pipe connected to the upper end of the hollow shell, and a diversion pipe connected to the other end of the first gas delivery pipe. A circular rod rotatably connected to the shell has vent holes distributed in an annular pattern, and an annular shell is rotatably connected to the outer wall of the circular rod through a sealed bearing. A second gas delivery pipe is connected to the circular rod, and the annular shell is connected to the diversion pipe.

[0022] In a preferred embodiment, the braking mechanism includes an air cylinder, which is fixedly connected to the frame by a bracket and is connected to a second air supply pipe. A T-shaped rod is slidably inserted into one end of the air cylinder, and a fourth spring is sleeved on the outer wall of one end of the T-shaped rod. A brake pad is fixedly connected to one end of the T-shaped rod, and a brake disc is fixedly connected to the lower end of the output shaft of the power motor.

[0023] The technical effects achieved by this invention are as follows:

[0024] This invention achieves intelligent and autonomous conversion of the rescue device from aerial flight to water navigation through a unique power mechanism layout and mechanical linkage automatic triggering mechanism. The instant the device hits the water, the float rises under buoyancy, causing the sealing ring to move and align the through-holes, allowing water to enter and trigger the expansion body to expand. The expansion body pushes the trapezoidal plate to release the mechanical lock on the moving block, which, under the action of the pre-compression return spring, drives the gear and rack mechanism, ultimately causing part of the power mechanism to flip from horizontal flight to vertical propulsion. This process requires no manual intervention, solving the problems of slow response and complex operation of traditional rescue equipment, as well as the need for manual or remote switching modes in existing flying rescue devices, significantly improving the speed and reliability of rescue response.

[0025] This invention features a dual heading control system that balances the safety of the rescued person's autonomous operation with the remote intervention capability of external rescuers. Once inside the device, the rescued person gains stable support by gripping the handles. By simply using a few fingers of one hand to manipulate the control lever, the heading is adjusted via a traction rope and pneumatic transmission system to control the brake pads. This "hands-on-hands" operation significantly enhances safety and stability, preventing the risk of slipping due to one or both hands leaving the grip point. Furthermore, the device includes a remote control system composed of electromagnets and permanent magnets. External rescuers can remotely intervene to control the heading if the rescued person becomes panicked or exhausted. This dual protection significantly improves the success rate and safety of the rescue.

[0026] The device of this invention is equipped with a dedicated handle to ensure that the rescued person can maintain a firm grip during high-speed navigation or sharp turns, effectively preventing slippage. Its core mode conversion mechanism adopts a mechanical linkage design, which is highly reliable, and the expansion body can be easily replaced after use. The mechanism can be reset and pre-tightened by manually rotating the adjustment knob, making maintenance convenient. Attached Figure Description

[0053] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0054] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0055] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0056] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0057] Please see the appendix Figures 1 to 10 As shown, this embodiment provides a multi-power mode flight rescue device, including a housing 1, with a power mechanism 2 provided at each of the four corners of the housing 1, and a power supply unit 7, an image acquisition unit 8 and a circuit board 9 installed inside the housing 1.

[0058] The power switching mechanism 3 is located at one end of the housing 1 and is used to switch the power mechanism 2 between air flight mode and water surface navigation mode.

[0059] Control components 4, both control components 4 are mounted on housing 1;

[0060] Gas delivery mechanism 5, two gas delivery mechanisms 5 are respectively mounted on two control components 4;

[0061] Braking mechanism 6, the two braking mechanisms 6 are respectively set on the two power mechanisms 2 that are far away from the image acquisition unit 8;

[0062] The power switching mechanism 3 includes a drive unit 31, which is located at the lower end of the housing 1. The inner cavity of the housing 1 is provided with a limit part 32. The housing 1 is also provided with a moving part 33, a transmission part 34 is provided at the moving part 33, and an adjustment part 35 is provided on the housing 1.

[0063] In this embodiment, two power units 2 are fixedly connected to the housing 1, while the other two power units 2 are rotatably connected to the housing 1. A power switching mechanism 3 allows the two power units 2 to remain horizontal or vertical to the housing 1, thereby enabling the switching between airborne flight mode and surface navigation mode. Specifically: when all power units 2 are horizontal to the housing 1, the device is in airborne flight mode; when two of the power units 2 are vertical to the housing 1, the device is in surface navigation mode.

[0064] Through the operation of the image acquisition unit 8 and the power mechanism 2, the life-saving device body approaches the target point, and then the device slowly descends onto the water surface.

[0065] The integrated circuit board 9 integrates at least a processing unit, a storage unit, and a signal transceiver unit. The signal transceiver unit is used to receive and send signals, the processing unit is used to process the signals and issue corresponding instructions, and the storage unit is used to store relevant information.

[0066] Secondly, please refer to it again. Figures 1 to 3 The power mechanism 2 includes a frame 21. Four frames 21 are located at the four corners of the housing 1. Two round rods 22 are fixedly connected to the frame 21. The round rods 22 on the two frames 21 located near the image acquisition unit 8 are fixedly connected to the housing 1, while the round rods 22 on the other two frames 21 are rotatably connected to the housing 1. A power motor 23 is fixedly mounted on the frame 21 using a bracket. A blade 24 is fixedly mounted on the output shaft of the power motor 23.

[0067] In this embodiment, after the power motor 23 starts, it drives the blades 24 to rotate at high speed, thereby generating powerful thrust to provide the life-saving device with the power for flight or navigation. Because the circular rod 22 on the frame 21 is connected to the housing 1 in different ways, when switching between flight and navigation modes, the power direction can be changed simply by adjusting the position of the frame 21, which is rotatably connected to the housing 1, through the power switching mechanism 3. This design makes the life-saving device more adaptable and flexible in complex environments.

[0068] Secondly, please refer to the following as well. Figures 11 to 13The drive unit 31 includes a hollow cylinder 311, which is threaded to the bottom surface of the housing 1. An annular groove 312 is formed on the hollow cylinder 311, and a sealing ring 313 is slidably connected within the annular groove 312. A first spring 3111 is fixedly connected between the annular groove 312 and the sealing ring 313. A partition 314 is fixedly connected inside the hollow cylinder 311, dividing it into an upper chamber and a lower chamber. An expansion body 3110 is placed in the upper chamber. A water inlet 315 is opened at the lower end of the hollow cylinder 311. A float 316 is placed in the lower chamber of the hollow cylinder 311, and the float 316 is fixedly connected to the sealing ring 313 by a support rod. A lifting rod 317 is piston-type inserted at the lower end of the housing 1 and at the hollow cylinder 311. A trapezoidal plate 318 is fixedly connected to the upper end of the lifting rod 317, and a circular plate 319 is fixedly connected to the lower end of the lifting rod 317.

[0069] In this embodiment, the hollow cylinder 311 has first through holes arranged in a ring, and the sealing ring 313 has second through holes arranged in a ring. In the initial state, the second through holes on the sealing ring 313 are offset from the first through holes on the hollow cylinder 311 to prevent external water and moisture from entering the interior of the hollow cylinder 311, thereby avoiding the influence of external water and moisture on the expansion body 3110.

[0070] Once it falls into the water, water will enter the lower chamber of the hollow cylinder 311 through the inlet hole 315, causing the float 316 to rise. The rise of the float 316 drives the sealing ring 313 to move upward along the annular groove 312, compressing the first spring 3111. When the float 316 drives the sealing ring 313 to rise to its maximum stroke, the sealing ring 313 coincides with the second through hole and the first through hole on the hollow cylinder 311. At this time, water can enter the interior of the hollow cylinder 311 through the first through hole and the second through hole. Subsequently, the expansion body 3110 expands when it encounters rainwater, pushing the circular plate 319, the lifting rod 317, and the trapezoidal plate 318 upward.

[0071] It should be noted that the expander 3110 includes an elastic mesh bag and a water-absorbing resin, with the water-absorbing resin contained inside the mesh bag. Furthermore, the water-absorbing resin is made of a high-speed water-absorbing material, which is characterized by its ability to rapidly expand upon contact with the water surface in a very short time, generating sufficient thrust to move the circular plate 319, thereby triggering the power switching mechanism 3 to operate and complete the transition from aerial flight mode to water surface navigation mode (preferably, the water-absorbing resin is sodium polyacrylate micropowder with a particle size between 50-200 micrometers).

[0072] Secondly, please refer to it again. Figure 10 and Figure 11The limiting part 32 includes a guide rail 321, which is fixedly connected to the bottom surface of the inner cavity of the housing 1. A locking block 322 is slidably connected on the guide rail 321. One end of the locking block 322 is trapezoidal, and a second spring 323 is sleeved on one end of the guide rail 321.

[0073] Please refer to it again. Figures 9 to 11 The movable part 33 includes a slide groove 331, which is formed on the bottom surface of the inner cavity of the housing 1. A movable block 332 is slidably connected in the slide groove 331. A first rack 333 is fixedly connected to the upper end of the movable block 332, and a second rack 334 is fixedly connected to the side of the movable block 332. A locking groove 335 is formed on the movable block 332. A return spring 336 is fixedly connected between the slide groove 331 and the movable block 332.

[0074] In this embodiment, as the trapezoidal plate 318 moves upward, its inclined surface abuts against the locking block 322, causing the locking block 322 to move along the guide rail 321 and compressing the second spring 323. Subsequently, the trapezoidal end of the locking block 322 disengages from the locking groove 335 on the moving block 332.

[0075] When the locking block 322 disengages from the locking groove 335, the moving block 332 loses its limit. Under the action of the restoring force of the return spring 336 (in the initial state, the return spring 336 is in a compressed state), the moving block 332 is pushed to move along the slide groove 331, and the movement of the moving block 332 drives the first rack 333 to move.

[0076] Please refer to it again. Figure 10 and Figure 11 The transmission unit 34 includes a transmission rod 341, which is fixedly connected between two round rods 22 that are rotatably connected to the housing 1. A first gear 342 is fixedly mounted on the transmission rod 341.

[0077] In this embodiment, the first rack 333 meshes with the first gear 342 to achieve transmission. When the first rack 333 moves, it drives the first gear 342 to rotate. The rotation of the first gear 342 then drives the transmission rod 341 to rotate, and the rotation of the transmission rod 341 drives the round rod 22 to rotate, thereby causing the power mechanism 2 to flip to adjust to the surface navigation mode.

[0078] Please refer to it again. Figure 1 and Figure 9 The adjustment part 35 includes an adjustment rod 351, which is rotatably connected to the housing 1 via a sealed bearing. A second gear 352 is fixedly installed at the lower end of the adjustment rod 351, and an adjustment knob 353 is fixedly connected to the upper end of the adjustment rod 351.

[0079] In this embodiment, after use, the hollow cylinder 311 can be removed from the housing 1, and the expansion body 3110 can be replaced. Then, the circular plate 319 is pulled, causing the lifting rod 317 and trapezoidal plate 318 to move downwards to achieve a reset. Before the next use, the adjusting knob 353 is rotated, causing the adjusting rod 351 to rotate, which in turn drives the second gear 352 to rotate. Since the second gear 352 meshes with the second rack 334, it drives the moving block 332 to move, causing the moving block 332 to compress the reset spring 336. During the movement of the moving block 332, when it contacts the inclined surface of the trapezoidal end of the locking block 322, it causes the locking block 322 to move along the guide rail 321 and compress the second spring 323. When the moving block 332 moves to the point where the locking groove 335 aligns with the trapezoidal end of the locking block 322, the locking block 322 is no longer resisted and is reset under the rebound force of the second spring 323, thereby allowing the locking block 322 to be inserted into the locking groove 335 to limit the movement of the moving block 332.

[0080] Please refer to it again. Figure 5 and Figure 6 The control component 4 includes a hollow shell 41, which is fixedly connected to the cavity of the housing 1. A piston plate 42 is slidably connected inside the hollow shell 41. A third spring 43 is fixedly connected to one side of the piston plate 42, and the other end of the third spring 43 is fixedly connected to the inner wall of the hollow shell 41. An electromagnet 44 is fixedly installed on the top surface of the inner cavity of the hollow shell 41. A handle 45 is fixedly connected to the top surface of the housing 1. A control rod 46 is slidably connected to the handle 45. A traction rope 47 is fixedly connected to the control rod 46, and the other end of the traction rope 47 passes through the hollow shell 41 and is fixedly connected to the piston plate 42.

[0081] In this embodiment, the traction rope 47 is cylindrical, and a sealing ring is provided at the point where the traction rope 47 passes through the hollow shell 41. When the piston plate 42 moves upward, the air inside the hollow shell 41 is compressed. Since a sealing ring is provided between the traction rope 47 and the hollow shell 41, air leakage is effectively prevented, ensuring that the pressure generated when the piston plate 42 moves can stably act on the relevant components.

[0082] Please refer to it again. Figure 2 , Figure 3 , Figure 7 and Figure 8 The gas supply mechanism 5 includes a first gas supply pipe 51, which is connected to the upper end of the hollow shell 41. The other end of the first gas supply pipe 51 is connected to a diversion pipe 52. A circular rod 22 rotatably connected to the shell 1 has vent holes 53 arranged in a ring. The outer wall of the circular rod 22 is rotatably connected to an annular shell 54 through a sealed bearing. A second gas supply pipe 55 is connected to the circular rod 22. The annular shell 54 is connected to the diversion pipe 52.

[0083] In this embodiment, the annular shell 54 is fixedly connected to the shell 1 by means of a support rod. When the round rod 22 rotates, it will not cause the annular shell 54 to rotate, thereby ensuring that the gas can be transmitted normally.

[0084] Please refer to it again. Figure 3 , Figure 6 and Figure 8 The braking mechanism 6 includes an air cylinder 61, which is fixedly connected to the frame 21 by a bracket and is connected to the second air supply pipe 55. A T-shaped rod 62 is slidably inserted into one end of the air cylinder 61. A fourth spring 63 is sleeved on the outer wall of one end of the T-shaped rod 62. A brake pad 64 is fixedly connected to one end of the T-shaped rod 62. A brake disc 65 is fixedly connected to the lower end of the output shaft of the power motor 23.

[0085] In this embodiment, after the person who has fallen into the water enters the rescue device, they should firmly grasp the handle 45 to enhance stability and prevent the person from falling out of the rescue device. In the water surface navigation mode, two power mechanisms 2 perpendicular to the shell 1 generate thrust to move the person to shore (the other two power mechanisms 2 are not activated).

[0086] When it is necessary to change the course of the rescue device, the person being rescued, while gripping handle 45, hooks some of their fingers onto control lever 46, causing control lever 46 to move upward. The upward movement of control lever 46 drives piston plate 42 upward via traction rope 47, which in turn compresses the air at the top of hollow shell 41. The compressed gas enters annular shell 54 along the first gas supply pipe 51 and the diversion pipe 52, then enters round rod 22 through vent 53, and continues to be transmitted downward along the second gas supply pipe 55.

[0087] After compressed gas enters the air cylinder 61 through the second air supply pipe 55, it pushes the T-shaped rod 62 to move and compresses the fourth spring 63. The movement of the T-shaped rod 62 causes the brake pad 64 to move, bringing it closer to the brake disc 65. The friction between the brake pad 64 and the brake disc 65 reduces the rotational speed of the blade 24, thereby reducing the power generated by the power mechanism 2. Therefore, the rescue device will deflect in this direction, thus adjusting its course and ensuring a safe and accurate arrival at the shore. Furthermore, when adjusting course, the rescued person can hold the handle 45 to ensure their safety and prevent slipping off the rescue device.

[0088] Furthermore, a permanent magnet (not shown in the figure) is embedded in the piston plate 42 below the electromagnet 44. Energizing the electromagnet 44 creates an attractive force, which in turn moves the piston plate 42 upwards, achieving the same goal of adjusting the course. External rescuers only need to control the energization of the electromagnet 44 to easily manipulate the movement of the piston plate 42, thereby changing the course of the rescue device. This provides convenience for external rescuers; when rescued individuals are panicked and unable to effectively adjust their course, they can assist in controlling the course, greatly improving the efficiency and success rate of the rescue and providing stronger protection for the lives of those being rescued.

[0089] The working principle of this invention is as follows:

[0090] When the device approaches the person falling into the water from the air and lands on the water surface, the float 316 in the drive unit 31 rises due to water ingress, causing the sealing ring 313 to move and open the through hole. Water enters the hollow cylinder 311, triggering the expansion body 3110 to rapidly absorb water and expand, pushing the lifting rod 317 and trapezoidal plate 318 upward, pushing open the locking block 322 in the limiting part 32, and releasing the locked moving part 33. Under the action of the return spring 336, the moving block 332 drives the first rack 333 to move, and through meshing with the first gear 342, it causes the transmission rod 341 to rotate, thereby driving the two rotatable power mechanisms 2 to flip from a horizontal state to a vertical state. The system switches from air flight mode to water navigation mode. At this time, two vertically arranged power units 2 provide water propulsion, while the other two power units 2 are deactivated. During navigation, the rescued person can pull up the control lever 46 to use the traction rope 47 to drive the piston plate 42 to compress air. The airflow is delivered to the braking mechanism 6 through the air supply mechanism 5, pushing the brake pads 64 to press against the brake disc 65, thereby decelerating the corresponding power unit 2 and adjusting the course. Alternatively, external rescuers can remotely control the electromagnet 44 to attract the permanent magnet, automatically triggering the process to ensure that the rescue device can stably and controllably move towards a safe area.
