The working principle of the amphibious rescue device provided by the invention is as follows:

after receiving a rescue signal, the control assembly 75 starts the driving motor 22, the driving motor 22 drives the traveling gear 25 to rotate through the driving gear 24, the traveling gear 25 drives the wheel 26 at the rear end of the chassis 21 to rotate through the rear wheel rod 23, the wheel 26 drives the whole structure to move, the two wheels 26 at the front end of the chassis 21 roll, and meanwhile, the damping springs 27 uniformly distributed on the top surface of the chassis 21 stretch up and down to counteract vibration and reduce the shaking of the vehicle body 1; when the vehicle is turned, the turning motor 51 drives the transmission gear 53 to rotate through the connecting gear 52, the transmission gear 53 drives the turning gear 55 to rotate through the connecting rod 54, and the turning gear 55 drives the steering gear 57 to transversely swing through the rack 56, so that the front end of the chassis 21 is driven to turn the wheels 26, and the purpose of changing the advancing direction of the whole device is achieved by matching with the power structure 2. After reaching the wounded position, pulling the handle 33 to open the cabin door 31, then placing the wounded inside the vehicle body 1, placing the wounded on the protective pad 71, placing the head on the headrest 73, wherein the fixing strap 72 is wound around the chest, waist or leg of the wounded to fix the wounded, and the wounded can also hold the side handrail 74 by himself to improve stability, and then pulling the handle 33 again to re-clamp the cabin door 31 on the top surface of the vehicle body 1, and the ventilation holes 34 and the ventilation slots 32 on the top surface and the side surfaces of the cabin door 31 can ensure that the inside of the vehicle body 1 is communicated with the outside air, so that the wounded can breathe smoothly; after the wounded person receives the signal, the control assembly 75 controls the driving motor 22 and the steering motor 51 to return in the above manner. When the integral structure runs on a road, the supporting curved rod 83 on the side wall of the vehicle body 1 is naturally unfolded, the hub 94 rotates at the bottom end of the supporting curved rod 83, when the vehicle body 1 shakes or has a rollover tendency in the running process, the hub 94 on the corresponding side lands, the hub 94 rotates around the rotating shaft 91 after contacting with the ground, meanwhile, the top of the supporting curved rod 83 rotates around the connecting shaft 81, the shock absorber 84 stretches and retracts to change, so that the impact force is offset and support is provided, and the supporting curved rod 83 and the hub 94 are matched together to play a role in preventing the vehicle body 1 from rolling over; when the rescue equipment enters a waterway, the driving motor 22 stops working, the whole rescue device enters water, the bottom floating block 62 at the bottom of the chassis 21 sinks into the water, the side floating block 61 on the side wall of the vehicle body 1 floats on the water surface, so that the vehicle body 1 floats on the water surface, meanwhile, the adjusting motor 85 drives the sliding gear 87 to rotate through the telescopic cylinder 86, the sliding gear 87 slides in the adjusting groove 89a on the adjusting column 89 by driving the sliding block 88 on the inner wall thereof, so as to push the sliding gear 87 to rotate around the adjusting column 89 and slide along the adjusting groove 89a, the telescopic cylinder 86 extends synchronously, the sliding gear 87 is meshed with the adjusting gear 82 after sliding for a certain distance, the sliding gear 87 still slides along the adjusting groove 89a after meshing connection, because the height (thickness) of the adjusting gear 82 is larger than that of the sliding gear 87, the sliding gear 87 can still drive the adjusting gear 82 to rotate after meshing with the adjusting gear 82, the adjusting motor 85 drives the adjusting gear 82 to rotate around the adjusting gear 82 through the telescopic cylinder 86 and the adjusting gear 82, the adjusting gear 82 drives the adjusting gear 83 to rotate around the top end of the supporting rod 92, the lifting rod 93 is connected with the hydraulic rod supporting rod 93, the lifting rod 93 is connected with the lifting rod 93, the lifting rod 93, the lifting rod structure, the lifting rod 93 is connected with the lifting rod 93, and the lifting rod structure, and the lifting rod 93, and the lifting rod supporting structure, the lifting rod 93 is connected with the adjusting gear 83; finally, the supporting curved rod 83 drives the anti-overturning structure 9 to rise above the water surface. In the process of rotation of the hub 94, the top rod 101 at the bottom surface of the supporting curved rod 83 presses the trigger ring 104 downward, the trigger ring 104 drives the striker 105 to slide downward, the striker 105 compresses the return spring 106 and simultaneously triggers the inflation assembly 102 at the lower end thereof, the inflation assembly 102 inflates the airbag 103, the airbag 103 pops out from the baffle disc 95 and rapidly expands to the maximum volume, the airbag 103 enables the four hubs 94 to float on the water surface and provides partial buoyancy for the overall structure, and the supporting curved rod 83 supports the hubs 94, so that the balance and buoyancy of the overall device are improved, the overall device can stably float on the water surface, and rollover and other situations cannot occur. The propulsion motor 41 is then activated, causing the propeller 43 to rotate within the protective cover 42, thereby propelling the rescue device forward. After returning to the road, the propulsion motor 41 is turned off, the driving motor 22 is turned on, the wheel 26 drives the rescue equipment to continue moving, and at the same time, the adjusting motor 85 drives the sliding gear 87 to rotate reversely through the telescopic cylinder 86, so as to drive the slider 88 to slide reversely in the adjusting groove 89a, so that the sliding gear 87 slides reversely along the adjusting column 89, the telescopic cylinder 86 shortens until the slider 88 returns to the lowest end of the adjusting groove 89a, in this process, the sliding gear 87 drives the adjusting gear 82 to rotate reversely, the adjusting gear 82 drives the supporting curved rod 83 to return, the shock absorber 84 rotates and shortens, the supporting curved rod 83 drives the anti-overturning structure 9 to reset, at the same time, the hydraulic rod 92 retracts, the top end thereof pulls the connecting convex column 93 while rotating with the connecting convex column 93, the connecting convex column 93 drives the rotating shaft 91 and the bottom end of the supporting curved rod 83 to rotate, and the rotating shaft 91 drives the hub 94 to reset until the sliding gear 87 separates from the adjusting gear 82, so that the sliding gear 86 and the adjusting cylinder 86 stop the rotating of the adjusting rod 85, the triggering curved rod 106 is lifted by the resetting spring 104, and the resetting spring 104 does not drive the triggering rod 104 in this process, and the resetting spring 104. After the rescue device returns, the handle 33 is pulled to open the cabin door 31, the fixing belt 72 is unfastened, the wounded person is lifted out of the inside of the vehicle body 1, and then the handle 33 is pulled to close the cabin door 31.
