[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. After the rescue boat of the present invention approaches the target, the lifebuoy launching mechanism can quickly release the lifebuoy toward the target, or the manipulator can grasp the first lifebuoy and throw it toward the person to be rescued. The lifesaving lifting mechanisms on both sides of the hull are used for the person to climb. At this time, the water jet propulsion mechanism tilts the water outlet pipe downward, adjusts the spray tilt angle, and increases the bow draft to balance the hull. When the manipulator grasps the lifebuoy or the person to be rescued climbs onto the unmanned boat, the water jet propulsion mechanism adjusts the water outlet pipe upward, reduces the bow draft, and adjusts the hull balance. This solves the problem of hull imbalance during the rescue process (such as throwing the lifebuoy or the person climbing), improves the stability of the rescue boat, and ensures the smooth progress of the rescue process. At the same time, this invention significantly improves the response speed, operation accuracy, and safety of water rescue.

[0019] 2. In the present invention, the water jet propulsion mechanism drives the transmission shaft through the main drive motor in the third equipment area inside the hull through the coupling, driving the propeller in the water outlet pipe to rotate at high speed, creating a pumping effect. Water flows from the lower end of the suction pipe at the bottom of the hull and enters after being filtered by the filter screen. It is then accelerated and guided through the bellows and jet swash plate in sequence, and finally discharged from the water outlet pipe, providing forward propulsion for the hull. At the same time, the cylinder on the connecting plate is hinged to the hull through the telescopic end, which can accurately control the up and down tilt angle of the water outlet pipe with an adjustment range of ±10°, achieving dynamic balance control of the hull's draft depth. The transmission shaft of the present invention is outer-mounted with a transmission sleeve, the inner wall of which is sealed by a mechanical shaft seal assembly, effectively preventing water in the suction pipe from penetrating into the interior of the hull, ensuring the sealing and durability of the transmission system, and improving the reliability and service life of the propulsion mechanism.

[0020] 3. In the present invention, the lifebuoy launching mechanism drives the cross column at the end of the control rod to rotate through the launching motors placed in the slots on both sides of the front end of the hull. When the cross column rotates in the matching slot until it is aligned with the cross slot, the springs on both sides of the launching plate release the elastic potential energy, pushing the launching plate to pop out along the inclined plate, and quickly pushing the second lifebuoy placed on the inclined plate to the target water area; after the launch is completed, the launching plate finally stops on the inclined plate under the restriction of the spring, which is convenient for reset and use next time.

[0021] 4. In the present invention, the lifesaving lifting mechanism drives the screw to rotate through the lifting motors on both sides of the hull, and the nut block screwed with the screw slides along the axis of the screw in the fixed frame, thereby driving the outer lifesaving frame to rise and fall synchronously; when the person to be rescued grabs or rides on the lifesaving frame, the lifting motor rotates forward to drive the screw to rotate, and the nut block drives the lifesaving frame to rise at a uniform speed, allowing the person to quickly escape from the flooded area.

DETAILED DESCRIPTION

[0034] The present invention will be further described below with reference to the accompanying drawings and examples, but they are not intended to limit the present invention.

[0035] Embodiment: A multifunctional unmanned patrol and rescue boat, comprising Figure 1-11As shown, the hull 1 includes a first equipment area 5 provided at the front middle of the hull 1, on which a drone 3 and a first life buoy 4 are placed. The drone 3 can expand the search and rescue range in the water area; manipulators 2 are provided on both sides of the first equipment area 5. The manipulators 2 can expand the rescue mode of the unmanned boat. When in use, they can be used to rotate, pitch, and grasp the life buoy. When necessary, they can directly act on the wrist or arm of the person to be rescued for rescue. When not in use, the manipulators 2 are symmetrically distributed and can be used to adjust the balance of the hull 1 to ensure draft and stability. The rescue boat also includes:

[0036] Water jet propulsion mechanism 17, such as Figure 5 and Figure 6 As shown, it is arranged on both sides of the stern of the hull 1, including a water outlet pipe 1702 connected to the hull 1 and an angle adjustment mechanism arranged on the hull 1; a propeller 1704 is arranged in the water outlet pipe 1702; the adjustment end of the angle adjustment mechanism is connected to the water outlet pipe 1702, and is used to adjust the jet inclination angle of the water outlet pipe 1702;

[0037] Lifebuoy launching mechanism 21, as Figure 7-Figure 9 As shown, it is arranged on both sides of the front end of the hull 1; the lifebuoy launching mechanism 21 is used to quickly release the lifebuoy to the target;

[0038] Lifesaving lifting mechanism 20, such as Figure 10 As shown, it is arranged on both sides of the hull 1; the lifesaving lifting mechanism 20 brings the rescued person up after he or she gets on it and gets rid of the water.

[0039] Preferably, if Figure 5 and Figure 6As shown, the outlet pipe 1702 is connected to the hull 1 via a bellows 28; a third equipment area 41 is provided at the rear end of the interior of the hull 1, and a suction pipe 1707 and a main drive motor 23 on the front side of the suction pipe 1707 are provided on the third equipment area 41; the water suction port of the suction pipe 1707 is provided at the bottom of the hull 1, and the water outlet of the suction pipe 1707 is connected to the bellows 28; the output end of the main drive motor 23 is connected to the transmission shaft 31 via a coupling 32, and the transmission shaft 31 passes through the suction pipe 1707 and extends into the outlet pipe 1702 to be connected to the propeller 1704. The angle adjustment mechanism includes a connecting plate 1703 arranged on the outside of the water outlet pipe 1702, and a plurality of cylinders 1705 are provided on the connecting plate 1703, and the output end of the cylinder 1705 is hinged to the hull 1; the outer end of the cylinder 1705 is fixedly connected to the connecting rod 1708, and the outer end of the connecting rod 1708 is connected to the shell cover 1701 located on the outside of the water outlet pipe 1702, and the shell cover 1701 can reduce damage to personnel during rescue. A jet swash plate 1706 is installed between the bellows 28 and the suction line 1707. A transmission sleeve 29 is sheathed around the drive shaft 31, and a mechanical shaft seal assembly 30 is installed at its inner end. This mechanical shaft seal assembly 30 is a conventional, commercially available component primarily composed of a silicon carbide dynamic ring, a ceramic static ring, and an O-ring. A spring forces the dynamic and static rings into close contact, forming an axial sealing surface that prevents water from entering the hull 1. A filter screen 27 is installed at the inlet end of the suction line 1707 to filter out impurities in the water. The third equipment area 41 houses an electrical box for controlling the main drive motor 23. The water jet propulsion mechanism 17 drives the transmission shaft 31 to rotate through the main drive motor 23 of the third equipment area 41 inside the hull 1 through the coupling 32, driving the propeller 1704 in the water outlet pipe 1702 to rotate at high speed, producing a pumping effect, so that the water flows from the lower end of the suction pipe 1707 at the bottom of the hull 1 and enters after being filtered by the filter 27, and is accelerated and diverted through the jet swash plate 1706 and the bellows 28 in turn, and is finally discharged from the water outlet pipe 1702, providing forward power for the hull 1. At the same time, the cylinder 1705 on the connecting plate 1703 of the angle adjustment mechanism is hinged to the hull 1 through the telescopic end, which can accurately control the up and down tilt angles of the water outlet pipe 1702 with an adjustment range of ±10°, thereby realizing dynamic balance control of the draft depth of the hull 1; a transmission sleeve 29 is arranged on the outer surface of the transmission shaft 31, and its inner wall is sealed by a mechanical shaft sealing assembly 30, which effectively prevents the water flow in the suction pipe 1707 from penetrating into the interior of the hull 1, thereby ensuring the sealing and durability of the transmission system and improving the reliability and service life of the propulsion mechanism.

[0040] Preferably, if Figure 11As shown, the jet swash plate 1706 is a disc-shaped component with an inward-inclined through-hole in its center. When water flows through the suction line 1707 and into the bellows 28, it first passes through the through-hole in the center of the jet swash plate 1706. Due to the contraction of the through-hole, the cross-sectional area of the flow path gradually decreases along the direction of the water flow. According to the continuity principle of fluid mechanics, when water flows through a contracting channel, the flow velocity increases significantly as the cross-sectional area decreases, forming a high-speed water flow. Furthermore, the jet swash plate 1706 works in conjunction with the propeller 1704. The propeller 1704 generates pumping power through rotation, imparting initial kinetic energy to the water flow, while the inclined through-hole in the jet swash plate 1706 further amplifies the flow velocity. The combination of the two significantly improves the thrust output efficiency of the waterjet propulsion mechanism, while providing stronger power support for the dynamic adjustment of the ship's draft depth.

[0041] Preferably, if Figure 2 and Figure 3 As shown, a visual navigation mechanism 43 is also provided above the hull 1. The visual navigation mechanism 43 includes a support platform 8 positioned in the middle of the upper end of the hull 1. A protective housing 14 is positioned above the support platform 8, and a visual camera 13 is positioned above the protective housing 14. Slanted rods 15 are positioned on either side of the protective housing 14, with a crossbeam 12 connected between their upper ends. A navigation radar 11 is positioned above the crossbeam 12. A second bracket 39 is fixedly connected within the protective housing 14, on which a camera drive motor 38 is positioned. The output end of the camera drive motor 38 is connected to a rotating shaft 22, the top of which is connected to the visual camera 13. An inspection baffle 16 is detachably connected to the front end of the protective housing 14. The camera drive motor 38 is connected to the rotating shaft 22, and through an articulated connection, it facilitates changes in the rotation and pitch angles of the visual camera 13. The visual camera 13 utilizes an optical camera with high detection accuracy and strong anti-interference capabilities. When in use, the visual camera 13 rotates to identify the person to be rescued, and feeds back to the control box 26 to adjust the water jet propulsion mechanism 17 and the rudder blade 18 of the hull 1 to make the hull 1 close to the person to be rescued.

[0042] Preferably, if Figure 5 As shown, the third equipment area 41 is symmetrically equipped with rudder drive motors 34. A rudder shaft 42 is symmetrically connected to the rear end of the hull 1 for rotation. The lower end of the shaft 42 extends beyond the hull 1 and is connected to the rudder 18. The rudder drive motor 34 is connected to the shaft 42 via a gear transmission. When rescuing a target, the rudder 18 at the rear is driven by the rudder drive motor 34 to adjust the left and right deflection of the boat, achieving precise positioning.

The lifebuoy launching mechanism 21 drives the cross column 2104 at the end of the control rod 2103 to rotate through the launching motor 2102 placed in the slots 2101 on both sides of the front end of the hull 1. When the cross column 2104 rotates in the matching slot 2106 until it is aligned with the cross slot 2107, the springs 2108 on both sides of the launching plate 2105 release their elastic potential energy, pushing the launching plate 2105 to pop outward along the inclined plate 2109, and quickly pushing the second lifebuoy 2110 placed on the inclined plate 2109 to the target water area; after the launch is completed, the launching plate 2105 finally stops on the inclined plate 2109 under the restriction of the spring 2108, which is convenient for reset and use next time.

[0047] Working principle:

[0048] The UAV 3 conducts patrol and reconnaissance in the waters. After identifying the target information, the rescue boat relies on the positioning guidance of the navigation radar 11 to approach the target waters, and then uses the visual camera 13 to identify the target. At the same time, the bow millimeter wave radar and the stern laser radar provide real-time feedback of position and speed information for accurate positioning. After approaching the target, rescue can be carried out in two ways: one is that the launch motor 2102 of the lifebuoy launch mechanism 21 drives the control rod 2103 to rotate, and when the cross column 2104 at the end of the control rod 2103 and the cross slot 2100 of the launch plate 2105 are aligned, the rescue boat can be rescued in two ways. 7, the spring 2108 pushes the launching plate 2105 to quickly pop out the second lifebuoy 2110 along the inclined plate 2109 to the target water area. Secondly, the manipulators 2 on both sides of the first equipment area 5 grab the first lifebuoy 4 and throw it. At this time, the cylinder 1705 of the water jet propulsion mechanism 17 drives the water outlet pipe 1702 to tilt downward, increasing the bow draft to balance the hull 1; when the rescued person grabs the lifebuoy or climbs to the hull 1 through the anti-slip claws at the end of the manipulator 2, the cylinder 1705 of the water jet propulsion mechanism 17 adjusts the water outlet pipe 1702 to tilt upward, reducing Bow draft; when the rescued person grasps or leans on the life-saving frame 2005, the life-saving lifting mechanism 20 on both sides of the hull 1 drives the screw 2003 to rotate through the lifting motor 2001, driving the nut block 2004 and the life-saving frame 2005 to rise, and taking the person out of the water; during navigation, the rudder blade 18 drives the motor to control the rudder blade 18 shaft to realize the steering of the hull 1, the main drive motor 23 drives the transmission shaft 31 through the coupling 32 to drive the propeller 1704 to rotate, and the water flows from the suction pipe 1707 through the filter screen 27 and is filtered through the bellows 28. After acceleration, the jet swash plate 1706 is discharged from the water outlet pipe 1702, providing forward propulsion for the hull 1. The mechanical shaft seal assembly 30 on the outside of the drive shaft 31 prevents water from penetrating into the interior of the hull 1. The battery pack 24 provides power to various devices in a partitioned manner to ensure system operation. The embedded structure and bolt sealing design of the watertight hatch 9 ensure the watertightness of the hull 1. The lifting lug 19 facilitates maintenance personnel to enter the interior for maintenance. The entire system realizes intelligent operation of the entire process from target reconnaissance and precise positioning to rapid rescue and stable navigation through the collaborative operation of multiple mechanisms.
