Description

Technical Field

[0001] This invention relates to the field of lifesaving equipment technology, specifically an intelligent autonomous water rescue device. Background Technology

[0002] Water rescue equipment plays a vital role in maritime search and rescue and flood disaster scenarios. Common rescue devices in existing technologies mainly include lifebuoys, lifeboats, and remotely operated underwater vehicles (ROVs). These devices typically rely on manual throwing or simple remote control operation. Lifebuoys require rescuers to throw them from close range, while lifeboats or ROVs often use a single drive method (such as propeller propulsion) for movement. Some high-end devices are equipped with basic sensors to detect the aquatic environment. In practical applications, these devices can meet rescue needs in calm waters to a certain extent, such as assisting people in swimming pools or lakes to grab onto buoys, or using remotely operated robots to tow stranded individuals in shallow water.

[0003] Existing water rescue devices have significant limitations when facing complex water environments (such as windy, wave-filled, and overgrown areas): a single drive mode cannot adapt to different water conditions, causing the propeller to easily become entangled or spin idly; insufficient buoyancy adjustment capability makes it difficult to dynamically respond to changes in wave height; the rescue equipment has limited functionality and cannot automatically adjust the rescue strategy according to the condition of the person being rescued; and there is a lack of rapid response mechanism in multi-target rescues, relying on manual intervention, resulting in low overall rescue efficiency. Therefore, in view of the above situation, there is an urgent need to develop an intelligent autonomous water rescue device to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent autonomous water rescue device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An intelligent autonomous water rescue device includes a main rescue shell, on which a drive device is provided for moving the main rescue shell within the water area, and further includes:

[0007] The U-shaped adjustment groove is formed on the main rescue housing, and a rescue adjustment ring plate is provided inside the U-shaped adjustment groove. A life-saving device is fixedly installed on the rescue adjustment ring plate.

[0009] A buoyancy-adjusting airbag is fixedly installed on the rescue adjustment ring plate and connected to the air supply system;

[0010] The system also includes a rescue control module, which is fixedly installed on the main rescue housing and is connected to the drive equipment, the air supply system, and the power module via signals.

[0011] As a further aspect of the present invention, it also includes: a cabin cover plate, which is detachably mounted on the main rescue shell;

[0012] And a handle, which is fixedly mounted on the cabin cover.

[0013] As a further aspect of the present invention: the driving device includes:

[0014] A spiral propulsion unit, which is fixedly installed at the tail end of the main rescue housing;

[0015] And a jet propulsion unit, which is fixedly connected to the main rescue housing and located below the spiral propulsion unit, and the jet propulsion unit is also connected to the air supply system;

[0016] When the buoyancy regulating airbag lifts the main rescue hull upward and causes the spiral propulsion unit to emerge from the water surface, the air supply system circulates air into the jet propulsion unit, thereby switching between the two power units.

[0017] As a further aspect of the present invention, it also includes a V-shaped cutting section, which is fixedly installed on the jet propulsion section and located on one side of the rescue main housing in the forward direction.

[0018] As a further aspect of the present invention: the air supply system is connected to the life-saving device through air pipe two, and the air supply system is connected to the buoyancy regulating airbag through air pipe one;

[0019] The power module includes a rotary drive component and a rotary connecting shaft. The rotary drive component is fixedly installed on the main rescue housing, and the rotary connecting shaft is connected to the rotary drive component and the rescue adjustment ring plate respectively.

[0020] As a further aspect of the present invention, it also includes: a V-shaped flow guide head, wherein the V-shaped flow guide head is fixedly installed at the end of the rescue main housing;

[0021] And a flow guide slot, which is opened on the main rescue shell and located near the buoyancy adjustment airbag.

[0022] As a further aspect of the present invention, it also includes: a playback speaker, which is fixedly mounted on the main rescue housing and signal-connected to the rescue control module.

[0023] As a further aspect of the present invention, it also includes: a rescue ejection device, which is fixedly installed on the rescue adjustment ring plate;

[0024] The rescue ejection device adopts a storage compartment structure to hold a spare lifebuoy in a rolled-up state. The spare lifebuoy is fixedly connected to the rescue ejection device through a connecting rubber sleeve, which is also connected to the air supply system.

[0025] The system also includes a pneumatic ejection control unit, which is fixedly installed on the rescue adjustment ring plate and connected to the rescue ejection device, for driving the spare life ring to eject outwards from the rescue ejection device.

[0026] As a further aspect of the present invention: the rescue control module includes:

[0027] The central processing unit (CPU) is used to execute control commands.

[0028] A multi-sensor fusion system, comprising:

[0029] The water condition detection unit, located at the front and bottom of the main rescue shell, includes a millimeter-wave radar, a visual recognition unit, and a water condition analyzer, used to detect wave height, weed density, and water flow parameters in real time.

[0030] The vital signs monitoring unit, located on both sides of the V-shaped flow guide head, includes an infrared thermal imager and a motion capture sensor, used to identify the location and movement frequency of the person in need of rescue.

[0033] The audio control unit, connected to the playback speaker, is used to generate low-frequency soothing voice messages.

[0034] As a further aspect of the present invention: the rescue control module performs the following steps:

[0035] (1) Determine the water area type through the water condition detection unit:

[0036] When the wave height is greater than 0.5m, the air supply system is controlled to release the gas in the buoyancy regulating airbag to make the main rescue shell sink.

[0037] When the weed density is >5kg / m³, inflate the buoyancy regulating airbag and switch to jet propulsion.

[0038] (2) Analyze the status of the person awaiting rescue through the vital signs monitoring unit:

[0039] If the action frequency is greater than 2 times / second, control the rescue adjustment ring plate to turn to a horizontal state and inflate the life-saving equipment;

[0040] If the action frequency is less than 0.5 times / second, control the rescue adjustment plate to flip to a vertical position and put the person into the rescue equipment to maintain chest compression pressure;

[0041] (3) When multiple targets are detected, the rescue ejection device is triggered to eject, and the backup lifebuoy is inflated simultaneously;

[0042] (4) Play soothing voice through the audio control unit and transmit location data back in real time through the communication unit.

[0043] Compared with the prior art, the beneficial effects of the present invention are:

[0044] 1. Adaptive water propulsion: Through the coordinated control of the dual drive system (propeller and jet propulsion) and buoyancy regulating airbag, the system can automatically switch the travel mode in complex waters such as wind, waves and weeds, avoid single point of failure, and improve navigation stability and efficiency.

[0045] 2. Intelligent rescue strategy: Based on the multi-sensor fusion system, the vital signs of the person in need of rescue are analyzed in real time, and the deployment mode of the rescue equipment is dynamically adjusted (horizontal grip or vertical wrap) to ensure that the person in poor condition is fixed and to avoid secondary injury.

[0046] 3. Rapid response to multiple targets: Through the linkage design between the pneumatic ejection control unit and the backup lifebuoy, simultaneous rescue of multiple targets can be achieved, with an ejection positioning error of less than 1.5 meters, significantly expanding the rescue coverage area;

[0047] 4. Environmental adaptability optimization: The V-shaped cutting section and the guide channel reduce water resistance and remove obstacles. Combined with dynamic buoyancy adjustment, the device can still operate efficiently when the wave height is >0.5m or the weed density is >5kg / m³.

[0048] 5. Rescue process support: Low-frequency voice reassurance and real-time GPS data transmission functions alleviate the panic of those awaiting rescue and provide accurate positioning support for the rescue center, thereby improving the overall rescue success rate.

Detailed Implementation

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0060] Please see Figures 1-8 An embodiment of the present invention provides an intelligent autonomous water rescue device, including a rescue main housing 1, wherein the rescue main housing 1 is provided with a driving device for driving the rescue main housing 1 to move in the water, and further includes:

[0061] U-shaped adjustment groove 2, the U-shaped adjustment groove 2 is opened on the rescue main shell 1, and a rescue adjustment ring plate 5 is provided in the U-shaped adjustment groove 2, and a life-saving device 14 is fixedly installed on the rescue adjustment ring plate 5;

[0062] The main rescue housing 1 is equipped with an air supply system 8 for inflating the rescue equipment 14, and the main rescue housing 1 is also equipped with a power module for driving the rescue adjustment ring plate 5 to rotate.

[0063] A buoyancy-adjusting airbag 16 is fixedly installed on the rescue adjustment ring plate 5 and connected to the air supply system 8.

[0064] And a rescue control module 9, which is fixedly installed on the rescue main housing 1, and is also connected to the drive equipment, the air supply system 8 and the power module by signal respectively.

[0065] Please see Figures 1-7 It also includes: a cabin cover 3, which is detachably installed on the rescue main shell 1;

[0066] And a handle 10, which is fixedly installed on the cabin cover 3.

[0067] The driving device includes:

[0068] A spiral propulsion unit 11 is fixedly installed at the tail end of the main rescue housing 1;

[0069] And a jet propulsion unit 12, which is fixedly connected to the rescue main housing 1 and located below the spiral propulsion unit 11, and the jet propulsion unit 12 is also connected to the air supply system 8;

[0070] When the buoyancy regulating airbag 16 lifts the rescue main shell 1 upward and causes the spiral propulsion part 11 to emerge from the water surface, the air supply system 8 circulates air into the jet propulsion part 12 to achieve the switching of the two sets of power equipment.

[0071] It also includes a V-shaped cutting section 15, which is fixedly installed on the jet propulsion section 12 and located on one side of the rescue main housing 1 in the forward direction.

[0072] During rescue operations, the main rescue shell 1 is first placed in the designated water area. The buoyancy regulating airbag 16 ensures the main rescue shell 1 floats stably on the water surface. Then, the drive unit moves the entire device on the water surface. The drive unit can utilize existing technology, using a detection unit on the rescue control module 9 to monitor the water conditions (calm water, turbulent water, and weedy water). The system then controls the air supply system 8 to inflate the buoyancy regulating airbag 16 to change the floating state of the main rescue shell 1. (For example, in turbulent water, some air needs to be expelled from the buoyancy regulating airbag 16 to allow the main rescue shell 1 to sink to the bottom of the water, preventing further buoyancy issues.) In the case of waterlogged areas, the spiral propulsion unit 11 is exposed above the water surface. In the case of weedy waters, the buoyancy regulating airbag 16 is inflated to move the main rescue shell 1 above the water surface. This reduces the drag on the main rescue shell 1 and exposes the spiral propulsion unit 11 above the water surface, preventing it from getting tangled in weeds. Another set of drive equipment (i.e., the jet propulsion unit 12) is then deployed to ensure that the rescue equipment can reach the relevant personnel smoothly and quickly. At the same time, the redundant design of the spiral propulsion unit 11 and the jet propulsion unit 12 solves the risk of single-point failure in existing water robots, thus adapting to different rescue water scenarios and ensuring the smooth progress of rescue operations.

[0073] After the main rescue shell 1 reaches the designated position, the rescue adjustment ring plate 5 and the life-saving device 14 (in the form of a life ring) can be controlled according to the physical condition of the person to be rescued (judged by sensors on the rescue control module 9; for example, weak movements may indicate poor physical condition, such as excessive exertion; remote control by the rescuer is also possible). When the person to be rescued is in good physical condition, the air supply system 8 directly inflates the life-saving device 14, and the rescue adjustment ring plate 5 changes from an inclined state to a horizontal state under the drive of the power module (when the inclined state moves to the side of the person to be rescued, it reduces the contact area with the water surface, reducing resistance). (And the buoyancy state of the main rescue shell 1 can be adjusted). After the rescue adjustment ring plate 5 is in a horizontal state, the rescue equipment 14 is also in an expanded state. Then the person to be rescued can directly pull on the rescue equipment 14 to achieve rescue (at this time, the person to be rescued is located outside the rescue equipment 14). When the person to be rescued is in poor physical condition, the rescue adjustment ring plate 5 will continue to tilt under the drive of the power module (until it approaches 90°, that is, close to the vertical state) so that the person to be rescued can be put into the rescue equipment 14. Then the rescue equipment 14 will expand to compress the chest cavity and other parts of the person to be rescued, thereby ensuring that the main rescue shell 1 can smoothly drag the person to be rescued to the shore and avoid the person to be rescued falling off the rescue equipment 14 due to physical exhaustion or other reasons during the dragging process, thus causing the rescue to fail.

[0074] The V-shaped cutting section 15 is used to cut weeds or other foreign objects in the water, preventing other debris in the water from entangled in the jet propulsion section 12, thereby ensuring the smooth movement of the rescue main shell 1. The V-shaped cutting section 15 is made of 304 stainless steel laser welding and the cutting edge is nitrided, which can effectively cut ropes and aquatic vegetation with a diameter ≤20mm.

[0075] Specifically, the multi-sensor fusion system (including millimeter-wave radar, visual recognition unit, and water condition analyzer) mounted on the rescue control module 9 collects water parameters in real time: in calm waters, the propeller propulsion unit 11 maintains normal operation; when wave height is detected to be >0.5m, the air supply system 8 discharges 30%-50% of the gas in the buoyancy regulating airbag 16, causing the main rescue shell 1 to sink 0.3-0.8m, preventing the propeller from spinning idly; in waters with weed density >5kg / m³, the airbag is inflated to make the shell float, triggering the jet propulsion unit 12 to replace the propeller drive. Considering the current state of water rescue robots, this invention improves travel efficiency by more than 40% through a dual-drive dynamic switching strategy. After the main rescue shell 1 approaches the target, it analyzes the frequency of the person to be rescued based on the vital signs sensor: if the limb movement is >2 times / second, the condition is judged to be good, the power module drives the rescue adjustment ring plate 5 to turn from a 45° tilt angle to a horizontal position, and the air supply system 8 completes the inflation of the life-saving device 14 within 5 seconds through the trachea 20, forming an external grasping life ring; if weak vital signs are detected (such as movement <0.5 times / second), the rotation drive component 18 is controlled to flip the ring plate to an 85° near-vertical state through the rotation connecting shaft 21, and the unconscious person is put into the life-saving device 14. After the airbag inflates, the pressure sensor module maintains a compression pressure of 8-12 kPa on the chest cavity to ensure that the person is fixed during the dragging process.

[0076] In one embodiment of the present invention, please refer to Figures 1-7 The air supply system 8 is connected to the life-saving device 14 via the second air pipe 20, and the air supply system 8 is connected to the buoyancy regulating airbag 16 via the first air pipe 19.

[0077] The power module includes a rotary drive component 18 and a rotary connecting shaft 21. The rotary drive component 18 is fixedly installed on the rescue main housing 1, and the rotary connecting shaft 21 is connected to the rotary drive component 18 and the rescue adjustment ring plate 5 respectively.

[0078] The rotary drive component 18 can be in the form of a forward and reverse motor and is located in the compartment inside the main rescue shell 1.

[0079] It also includes: a V-shaped flow guide head 4, which is fixedly installed at the end of the rescue main housing 1;

[0080] And a flow guide 17, which is formed on the main rescue shell 1 and is located near the buoyancy regulating airbag 16.

[0081] Through the hydrodynamic collaborative design of the V-shaped guide head 4 and the guide slot 17, the water resistance coefficient of the shell is optimized (the resistance is reduced by 18.7% as verified by CFD simulation).

[0082] It also includes a playback speaker 13, which is fixedly installed on the rescue main housing 1 and is signal-connected to the rescue control module 9.

[0083] The speaker 13 is used to broadcast the driving status of the main rescue housing 1 (such as speed, tilt status, etc.), and uses low-frequency (200-500Hz) soothing voice to alleviate the panic of the person waiting for rescue, and to prevent the main rescue housing 1 from being in a state of malfunction due to the nervous tension of the person waiting for rescue, which would lead to the failure of the rescue operation.

[0084] In one embodiment of the present invention, please refer to Figures 1-7 It also includes: a rescue ejection device 6, which is fixedly installed on the rescue adjustment ring plate 5;

[0085] The rescue ejection device 6 adopts a storage compartment structure to hold a spare life ring in a rolled-up state. The spare life ring is fixedly connected to the rescue ejection device 6 through a connecting rubber sleeve 7, which is also connected to the air supply system 8.

[0086] And a pneumatic ejection control unit 22, which is fixedly installed on the rescue adjustment ring plate 5 and connected to the rescue ejection device 6, for driving the spare life ring to eject to the outside of the rescue ejection device 6.

[0087] The backup lifebuoy can adapt to rescue operations involving multiple people, overcoming the limitations of a single lifebuoy in terms of buoyancy and volume. On the other hand, when the main rescue shell 1 cannot accurately reach the person to be rescued (e.g., due to limited rescue space or large waves), the backup lifebuoy can be expanded by ejection, allowing the person to be rescued to quickly grab the backup lifebuoy and achieve the rescue objective. It has a wider range of applications and is more practical.

[0088] Specifically, the multi-target rescue challenge is solved through the coordinated design of the pneumatic ejection control unit 22 and the air supply system 8. When infrared thermal imaging detects ≥2 people awaiting rescue, the rescue control module 9 triggers the ejection command: the pneumatic ejection control unit 22 releases 0.6MPa compressed air, launching the pre-rolled polyurethane spare lifebuoy inside the rescue ejection device 6 at an initial velocity of 12m / s. Simultaneously, the air supply system 8 inflates the lifebuoy within 0.8 seconds via the connecting rubber sleeve 7. This design overcomes the limitations of existing single-boat, single-lifebuoy systems, and is particularly suitable for scenarios where the main boat cannot approach when the wave height is >1.5m. The ejection angle is dynamically compensated by the real-time tilt angle of the rescue adjustment ring plate 5, with a positioning error of <1.5m.

[0089] In one embodiment of the present invention, please refer to Figures 1-8 The rescue control module 9 is the core intelligent control unit of the device, and mainly includes the following components:

[0090] The central processing unit (controller) is installed in the sealed compartment inside the main rescue shell 1 and is used to perform sensor data analysis, decision logic calculation and equipment command issuance.

[0091] Multi-sensor fusion system:

[0092] Water condition detection unit: Composed of millimeter-wave radar (detecting wave height), visual recognition unit (image analysis of water obstacles), and water condition analyzer (detecting water quality and flow velocity), it is installed at the front and bottom of the main rescue shell 1 and is used to collect parameters such as wave height, weed density, and water flow velocity in real time (such as triggering response strategies when wave height > 0.5m or weed density > 5kg / m³).

[0093] Vital signs monitoring unit: It consists of an infrared thermal imager (to locate the person in need of rescue) and a motion capture sensor (to analyze the frequency of limb movements). It is installed on both sides of the V-shaped guide head 4 at the front end of the main rescue housing 1. It is used to detect the frequency of the person in need of rescue (>2 times / second is considered good condition, <0.5 times / second is considered poor condition).

[0094] Pressure sensing module: installed inside the life-saving device 14, used to monitor the compression pressure of the life-saving device 14 on the chest cavity (maintained at 8-12 kPa).

[0095] Communication unit: Composed of a wireless transmission module (4G / 5G) and a GPS locator, used for data interaction with the remote rescue center and real-time transmission of location and rescue status;

[0096] Audio control unit: Composed of a low-frequency speech synthesizer (connected to playback speaker 13), used to generate 200-500Hz soothing voice to announce driving status (such as speed, tilt angle).

[0097] The installation locations of the above testing equipment can be adjusted according to actual needs, as long as they can achieve good testing functions. No specific installation location is specified for each testing equipment.

[0098] The specific control process of the rescue control module 9 is as follows:

[0099] Step 1: Adaptation to the aquatic environment;

[0100] Water condition detection unit scans water area parameters:

[0101] Calm waters: The propeller 11 is maintained in drive, and the buoyancy regulating airbag 16 maintains standard buoyancy;

[0102] In windy and wavy waters (wave height > 0.5m): Control the air supply system 8 to discharge 30%-50% of the gas in the buoyancy regulating airbag 16, so that the main rescue shell 1 sinks 0.3-0.8m and avoids the propeller spinning idly;

[0103] Weedy waters (density > 5 kg / m³): Inflate the buoyancy regulating airbag 16 to make the shell float, switch the jet propulsion unit 12 to drive, and activate the V-shaped cutting unit 15 to clear obstacles;

[0104] Step 2: Target Approach and Status Assessment;

[0105] The vital signs monitoring unit locates the person awaiting rescue and analyzes their movement frequency.

[0106] Good condition (actions > 2 times / second): The power module drives the rescue adjustment ring plate 5 to change from a 45° tilt angle to a horizontal position, and the air supply system 8 completes the inflation of the life-saving equipment 14 within 5 seconds through the air pipe 20, forming an external grab life ring;

[0107] In poor condition (movement < 0.5 times / second): the rotary drive 18 flips the rescue adjustment ring plate 5 to an 85° near-vertical state via the rotary connecting shaft 21, bringing the person into the rescue equipment 14; after the airbag inflates, the pressure sensing module maintains a chest compression pressure of 8-12 kPa.

[0108] Step 3: Multi-target rescue response;

[0109] When infrared thermal imaging detects ≥2 people awaiting rescue:

[0110] The rescue control module 9 triggers the ejection command: the pneumatic ejection control unit 22 releases 0.6MPa compressed air to eject the spare life ring at an initial velocity of 12m / s;

[0111] The air supply system 8 is inflated within 0.8 seconds via the connecting rubber sleeve 7, and the ejection angle dynamically compensates for the tilt of the rescue adjustment ring plate 5 (positioning error < 1.5m).

[0112] Step 4: Ensuring the safety and well-being of the rescue process;

[0113] The audio control unit continuously plays low-frequency reassuring voice messages to alleviate the panic of those awaiting rescue;

[0114] The pressure sensing module monitors the internal pressure of the life-saving device 14 in real time to ensure that personnel are secured during the towing process;

[0115] GPS location data is synchronously transmitted back to the rescue center, enabling full-process monitoring.
