DETAILED DESCRIPTION

[0058] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0059] The specific implementation of the present application will be described in detail below in combination with specific embodiments.

[0060] Please refer to Figures 1-8 The intelligent autonomous water area rescue device provided by the embodiment of the present application comprises a rescue main shell 1, a driving equipment for driving the rescue main shell 1 to move in a water area is arranged on the rescue main shell 1, and further comprises:

[0061] A U-shaped adjusting groove 2 is arranged on the rescue main shell 1, a rescue adjusting ring plate 5 is arranged in the U-shaped adjusting groove 2, and lifesaving equipment 14 is fixedly installed on the rescue adjusting ring plate 5.

[0062] The rescue main shell 1 is provided with a gas supply system 8 for inflating the lifesaving device 14, and is also provided with a power module for driving the rescue adjusting ring plate 5 to flip over;

[0063] A buoyancy adjusting air bag 16 is fixedly installed on the rescue adjusting ring plate 5 and is in communication with the gas supply system 8;

[0064] A rescue control module 9 is fixedly installed on the rescue main shell 1 and is in signal connection with the driving device, the gas supply system 8 and the power module respectively.

[0065] Please refer to Figures 1-7 The rescue main shell 1 is provided with a gas supply system 8 for inflating the lifesaving device 14, and is also provided with a power module for driving the rescue adjusting ring plate 5 to flip over;

[0066] A rescue control module 9 is fixedly installed on the rescue main shell 1 and is in signal connection with the driving device, the gas supply system 8 and the power module respectively.

[0067] The driving device comprises:

[0068] A spiral propelling part 11 is fixedly installed at the tail end of the rescue main shell 1;

[0069] A jet propelling part 12 is fixedly connected with the rescue main shell 1 and is located below the spiral propelling part 11, and is also connected with the gas supply system 8;

[0070] When the buoyancy adjusting air bag 16 lifts the rescue main shell 1 to move upwards and exposes the spiral propelling part 11 above the water surface, the gas supply system 8 supplies air into the jet propelling part 12, so as to realize the switching of the two sets of power devices.

[0071] The rescue main shell 1 is provided with a gas supply system 8 for inflating the lifesaving device 14, and is also provided with a power module for driving the rescue adjusting ring plate 5 to flip over;

[0072] In the rescue work, first, the rescue main shell 1 is put into the designated water area, the buoyancy adjusting air bag 16 is used to make the rescue main shell 1 float steadily on the water surface, then the driving device drives the whole device to move on the water surface, wherein the driving device can adopt the existing technology, the detection unit on the rescue control module 9 detects the water area (calm water area, stormy water area and grass water area), the air supply system 8 fills air into the buoyancy adjusting air bag 16 to change the floating state of the rescue main shell 1 (for example, in the stormy water area, part of the gas in the buoyancy adjusting air bag 16 needs to be discharged, so that the rescue main shell 1 is lowered as a whole into the water, to avoid that the spiral propelling part 11 is exposed above the water surface in the stormy condition, and in the grass water area, air is filled into the buoyancy adjusting air bag 16 to make the rescue main shell 1 move above the water surface, on the one hand, to reduce the resistance of the rescue main shell 1, and on the other hand, to expose the spiral propelling part 11 above the water surface to avoid the entanglement of grass, and another set of driving device (i.e. the jet propelling part 12) is put into use, so as to ensure that the rescue device reaches the relevant person smoothly and quickly, and the single point failure risk of the existing water robot is solved through the redundant design of the spiral propelling part 11 and the jet propelling part 12), so as to adapt to different rescue water area scenes and ensure the smooth progress of the rescue work.

[0073] After the rescue main shell 1 reaches the designated position, the action of the rescue adjusting ring plate 5 and the lifesaving device 14 can be controlled according to the body state of the person to be rescued (the behavior state of the person to be rescued is detected by the sensor on the rescue control module 9 to judge, for example, if the action amplitude is weak, it may represent that the body state of the person to be rescued is not good, such as too much physical exertion, of course, the remote operation of the rescuer can also be used for control), the lifesaving device 14 adopts the form of life buoy, when the body state of the person to be rescued is good, the air supply system 8 directly fills air into the lifesaving device 14, and the rescue adjusting ring plate 5 is driven by the power module to change from the inclined state to the horizontal state (when the inclined state moves to the side of the person to be rescued, the contact area with the water surface can be reduced to reduce the resistance, and the buoyancy state of the rescue main shell 1 can be adjusted), after the rescue adjusting ring plate 5 is in the horizontal state, the lifesaving device 14 is also in the inflated state, then the person to be rescued directly pulls the lifesaving device 14 to realize the rescue (at this time, the person to be rescued is located outside the lifesaving device 14), when the body state of the person to be rescued is not good, the rescue adjusting ring plate 5 is continuously inclined under the driving of the power module (until close to 90°, i.e. close to the vertical state), so as to put the person to be rescued into the lifesaving device 14, and then the lifesaving device 14 is inflated to press the chest and other parts of the person to be rescued, so as to ensure that the rescue main shell 1 drags the person to be rescued to the shore smoothly, to avoid that the person to be rescued falls off from the lifesaving device 14 in the dragging process due to physical exhaustion and other reasons, so as to cause the failure of the rescue.

[0074] The V-shaped cutting part 15 is used for cutting off the weeds or other foreign matters in the water area, avoiding the entanglement of other foreign matters in the water body to the jet propelling part 12, so that the rescue main shell 1 can move smoothly, wherein the V-shaped cutting part 15 is formed by laser welding of 304 stainless steel, and the cutting edge is treated by nitriding, so that the rope and aquatic vegetation with a diameter of ≤20 mm can be effectively cut off.

[0075] Specifically, through the multi-sensor fusion system (including millimeter wave radar, visual recognition unit and water condition analyzer) carried by the rescue control module 9, the water area parameters are collected in real time: in the calm water area, the spiral propelling part 11 is maintained in normal operation; when the wave height is detected to be > 0.5 m, the control gas supply system 8 discharges 30%-50% of the gas in the buoyancy adjusting gas bag 16, so that the rescue main shell 1 sinks by 0.3-0.8 m, and the propeller is avoided from idling; in the water area with a weed density > 5 kg / m³, the gas bag is inflated to make the shell float up, and the jet propelling part 12 is triggered to replace the propeller drive. In combination with the current situation in the field of water area rescue robots, the invention improves the advancing efficiency by more than 40% through the double-drive dynamic switching strategy. After the rescue main shell 1 approaches the target, the motion frequency of the person to be rescued is analyzed based on the vital sign sensor: if the limb movement is > 2 times / s, it is determined that the state is good, the power module drives the rescue adjusting ring plate 5 to be turned from a 45° inclination to a horizontal state, the gas supply system 8 completes the inflation of the lifesaving device 14 through the air pipe two 20 within 5 seconds, and an external gripping life buoy is formed; if weak vital signs (such as motion < 0.5 times / s) are detected, the rotating drive 18 turns the ring plate to an 85° near-vertical state through the rotating connecting shaft 21, and the unconscious person is put into the lifesaving device 14, and after the gas bag is inflated, the pressure sensing module maintains the extrusion pressure of 8-12 kPa on the chest cavity part, so as to ensure the fixation of the person during the dragging process.

[0076] In one embodiment of the present application, please refer to Figures 1-7 The gas supply system 8 is connected with the lifesaving device 14 through the air pipe two 20, and the gas supply system 8 is connected with the buoyancy adjusting gas bag 16 through the air pipe one 19.

[0077] The power module comprises a rotating drive 18 and a rotating connecting shaft 21, the rotating drive 18 is fixedly installed on the rescue main shell 1, and the rotating connecting shaft 21 is connected with the rotating drive 18 and the rescue adjusting ring plate 5 respectively.

[0078] The rotating drive 18 can adopt the form of a forward and reverse motor, and is located in the chamber in the rescue main shell 1.

[0079] Further comprising a V-shaped flow guide head 4, which is fixedly installed at the end of the rescue main shell 1.

[0080] And a guide groove 17 is arranged on the rescue main shell 1 and is arranged close to the buoyancy adjusting air bag 16.

[0081] Through the hydrodynamic synergy design of the V-shaped guide head 4 and the guide groove 17, the shell water resistance coefficient is optimized (the resistance reduction is verified by CFD simulation to be 18.7%).

[0082] Further comprising a playing speaker 13 fixedly installed on the rescue main shell 1 and signal-connected with the rescue control module 9.

[0083] The playing speaker 13 is used for reporting the driving state of the rescue main shell 1 (such as the speed, the inclination state and the like), adopting low-frequency (200-500Hz) soothing voice to relieve the panic emotion of the person to be rescued, and avoiding the rescue main shell 1 from being in the state of unable to normally work due to the nervous tension of the person to be rescued, thereby causing the failure of the rescue work.

[0084] In an embodiment of the present application, please refer to Figures 1-7 Further comprising a rescue ejection device 6 fixedly installed on the rescue adjusting ring plate 5.

[0085] The rescue ejection device 6 adopts the structure of a storage bin and is used for containing the standby life buoy in the rolled state, and the standby life buoy is fixedly connected with the rescue ejection device 6 through a connecting rubber sleeve 7, and the connecting rubber sleeve 7 is also connected in communication with the gas supply system 8.

[0086] And a gas pressure ejection control portion 22 is fixedly installed on the rescue adjusting ring plate 5 and is connected with the rescue ejection device 6, and is used for driving the standby life buoy to be ejected to the outside of the rescue ejection device 6.

[0087] The standby life buoy is arranged on one hand to adapt to the multi-person rescue work, overcome the defects of the limited buoyancy and volume of the single life buoy, and on the other hand, when the rescue main shell 1 cannot accurately reach the side of the person to be rescued (such as the limited rescue space or the large wave and the like), the standby life buoy is ejected and inflated at the same time, so as to make the person to be rescued quickly grab the standby life buoy, achieve the rescue purpose, and the application scenarios are more extensive and the practicality is stronger.

[0088] Specifically, through the linkage design of the air pressure ejection control part 22 and the air supply system 8, the multi-target rescue problem is solved. When the infrared thermal imaging detects ≥2 people to be rescued, the rescue control module 9 triggers the ejection instruction: the air pressure ejection control part 22 releases 0.6 MPa compressed air, and the pre-wound polyurethane standby life buoy in the rescue ejection device 6 is ejected at an initial speed of 12 m / s, and at the same time, the air supply system 8 completes the inflation of the life buoy through the connecting rubber sleeve 7 in 0.8 seconds. This design breaks through the limitation of the existing single boat and single life buoy, and is especially suitable for the scene where the main boat cannot approach when the wave height is >1.5 m. The ejection angle is dynamically compensated by the real-time inclination angle of the rescue adjustment ring plate 5, and the positioning error is <1.5 m.
