[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a drive mechanism, a rescue mechanism, and a floating plate, allows the user to rescuing a person who has fallen into the water. The user first places the entire device in the water. The user can then send a control signal to the control host via a wireless control terminal, causing the control host to operate two motors. When motor one operates, its output shaft drives the paddles through sprockets one and two, thus propelling the entire device across the water surface. During the movement of the device, the user can control one side of motor one to turn the entire device. When the entire device moves to the front of the person in the water, the user stops motor one and controls motor two to operate, using pulleys two and three to drive the screw to rotate clockwise. When the screw rotates clockwise, it drives the push plate and the grid plate downwards, causing the grid plate to enter the water. Then, the user controls... The first motor moves the entire device, causing the grid plate to move below the person in the water. The user then stops the first motor and reverses the output shaft of the second motor, causing the grid plate to move upward. This upward movement of the grid plate helps to lift the person out of the water. When the person moves above the water surface, the second motor stops working, facilitating the rescue of those in the water. This device can be used even when the person is exhausted, thus increasing the success rate of the rescue. After the rescue, the user can control the electric push rod to extend, using the gear plate and gears to drive the rotating shaft, the first motor, and the propeller to rotate upward by 90 degrees. This rotates the propeller above the float, preventing the propeller from contacting the ground and being damaged when the device is not in use, further increasing the functionality of the device.

[0014] 2. This invention connects the rescue mechanism to the floating board and the drive mechanism. While rescuing the person from the water onto the floating board and using the drive mechanism to transport them to the shore, motor one drives the fixed shaft and fan blades to rotate via bevel gear one, bevel gear two, connecting shaft two, connecting groove, connecting plate, connecting shaft three, pulley one, and pulley four. As the fan blades rotate, airflow is drawn into the heating box through the air inlet slot. The user then controls the heating plate to heat the airflow inside the heating box. The heated airflow is then blown towards the person in the water through a metal universal tube and air guide, thus heating and keeping them warm. It also dries the person's wet clothes, improving their comfort and preventing hypothermia during rescue. Attached Figure Description

[0022] The rescue mechanism 4 includes four screws 41. The four screws 41 are paired together, and their two ends are movably connected to the upper surfaces of the two floats 1 and the upper surface of the mounting frame 6 respectively through rolling bearings. The upper ends of the four screws 41 are fixedly connected to four pulleys 44. The four pulleys 44 are paired together, and the two pulleys 44 in the same group are connected by belt drive.

[0023] The upper end of the left front screw 41 is fixedly connected to the output shaft of motor 2 46. The upper end of motor 2 46 is fixedly connected to the inner side of mounting base 45. The bottom end of mounting base 45 is fixedly connected to the upper surface of mounting bracket 6. The input end of motor 2 46 is electrically connected to the output end of control host 8. When the device moves to the front of the person who has fallen into the water, the user stops motor 1 318 and controls motor 2 46 to drive screw 41 to rotate forward using pulley 2 44 and pulley 3 47. When screw 41 rotates forward, it drives push plate 42 and grid plate 48 to move downward so that grid plate 48 enters the water. Then the user controls motor 1 318 to move the device as a whole so that grid plate 48 moves to below the person who has fallen into the water. Then the user stops motor 1 318 and controls the output shaft of motor 2 46 to reverse so that grid plate 48 moves upward. Thus, the upward movement of grid plate 48 is used to lift the person who has fallen into the water. Four screws 41 are threadedly connected to four threaded holes 43 respectively.

[0026] The operation steps of this invention are as follows: When using this device to rescue a person who has fallen into the water, the user first places the entire device in the water. The user can then send a control signal to the control host 8 via the wireless control terminal, causing the control host 8 to control the two motors 318 to operate. When motor 318 is operating, its output shaft drives the propeller 36 to rotate through sprockets 32 and 35, thereby using the propeller 36 to propel the entire device to move on the water surface. During the movement of the device, the user can control one side of motor 318 to turn the entire device. When the entire device moves to the front of the person who has fallen into the water... The user stops motor 1 (318) from working and controls motor 2 (46) to work, using pulleys 2 (44) and 3 (47) to drive screw 41 to rotate forward. When screw 41 rotates forward, it drives push plate 42 and grid plate 48 to move downward, causing grid plate 48 to enter the water. Then, the user controls motor 1 (318) to work, causing the entire device to move so that grid plate 48 moves below the person who fell into the water. Then, the user stops motor 1 (318) from working and controls the output shaft of motor 2 (46) to reverse, causing grid plate 48 to move upward, thereby using the upward movement of grid plate 48 to lift the person out of the water. When the person who fell into the water moves to the surface, motor 2 46 stops working. While rescuing the person from the water onto the grid 48 and using the drive mechanism 3 to transport them to the shore, motor 1 318 drives fixed shaft 53 and fan blade 59 to rotate via bevel gear 1 33, bevel gear 2 38, connecting shaft 2 39, connecting groove 312, connecting plate 313, connecting shaft 314, pulley 1 315, and pulley 4 54. As the fan blade 59 rotates, it draws air into the heating box 51 through the air inlet slot 52, and then the user... The heating plate 57 is controlled to heat the airflow in the heating box 51. The heated airflow is blown towards the person who has fallen into the water through the metal universal tube 55 and the air guide shroud 56, thereby heating and keeping the person warm and drying their wet clothes. After the rescue is completed, the user can control the electric push rod 319 to extend and use the toothed plate 320 and gear 321 to drive the rotating shaft 310, motor 318 and blade 36 to rotate upward by 90 degrees, so that the blade 36 rotates to the top of the float 1 for storage and protection.
