Description

[0001] This application claims the priority of the Chinese patent application with the application number 2024107111117 and the title "Rescue Boat" filed on June 4, 2024. Technical Field

[0002] The utility model relates to the technical field of rescue equipment, and specifically refers to a rescue boat. Background Art

[0003] Existing unmanned water rescue boats cannot rescue multiple people at the same time. When multiple people are drowning, they cannot be rescued all at once, resulting in the loss of the rescue opportunity for the victims who originally had a chance of being saved. After retrieval, Chinese patent CN113859484A discloses a water rescue device, including: two hulls, which are parallel to each other and arranged side by side, with a gap between the two hulls; a connecting plate, which is placed between the two hulls to connect the two hulls, and the connecting plate is telescopic; a telescopic driving unit, which is placed between the two hulls to connect the two hulls, and the telescopic driving unit drives the two hulls to approach or move away from each other; two stern driving units, which are respectively arranged at the tails of the two hulls, and the stern driving units drive the hulls to move. The deficiencies of the above patent are as follows: When the hull or the connecting plate in the above patent rescues the victims, the victims need to have good behavioral awareness and action ability. For drowning victims without self-rescue awareness or self-rescue behavior, such as those in a state of blurred consciousness, physical exhaustion, or even in the golden rescue period of drowning, they cannot actively grasp the hull or the connecting plate, let alone enter the hull or onto the connecting plate. Even if they enter the hull or onto the connecting plate, they are likely to slip because they do not hold the handrail, and effective rescue cannot be carried out in time. Summary of the Invention

After entering the water, the hull control system starts the rescue net drive mechanism 3, and drives the net expansion and contraction electric push rod 10 to move towards the direction close to the first hinge plate 6. For the convenience of description, the orientation in the appendix Figure 3 is used to describe. The telescopic rod of the net expansion and contraction electric push rod 10 extends, driving the slider 9 to move to the left, so that the second hinge plate 7 moves left and down, and the first hinge plate 6 rotates downward to form the appendix Figure 3 or the appendix Figure 6In the open state, the left end of the rescue net 2 opens downward on both sides, and the right end of the rescue net 2 is fixedly connected to the first guide sleeve 19 and the second guide sleeve 20. The upper ends of the two sides of the right part of the rescue net 2 can also be fixedly connected to the first hull 11 and the second hull 12, so that the rescue net 2 opens to the left to form a shape like a dustpan. Then, the present invention can rescue the drowning person under the drive of the thruster 22. When rescuing the drowning person, for the drowning person without self-rescue awareness or self-rescue behavior, such as a person in a daze, exhausted, or even a drowning person in the golden rescue period, the left end of the rescue net 2 of the present invention is underwater, and the height of the left end of the rescue net 2 is much lower than the height of the right end of the rescue net 2. At this time, the present invention approaches the drowning person, and the rescue net 2 passes under the drowning person, so that the drowning person enters the rescue net 2, and the rescue net 2 holds the drowning person. Then the thruster continues to move forward, quickly sending the drowning person to the designated place, facilitating the rescuer to rescue the drowning person in the rescue net 2 in time. This process is repeated. When the rescue net 2 is not in use, the hull control system activates the net retracting and expanding electric push rod 10, driving the telescopic rod of the net retracting and expanding electric push rod 10 to retract, driving the slider 9 to move to the right, pulling the second hinge plate 7 to move to the right, and the second hinge plate 7 pulling the first hinge plate 6 to rotate upward and to the right until the first hinge plate 6 and the second hinge plate 7 are in an attached Figure 5 and attached Figure 7 retracted state, which is convenient for the transportation of the present invention. The present invention can not only rescue drowning persons without self-rescue awareness or self-rescue behavior, but also rescue drowning persons with good behavior awareness and action ability. Such drowning persons can grab the rescue net 2 or automatically enter the rescue net 2. The rescue net 2 of the present invention can be set deeper and larger, facilitating the rescue of multiple drowning persons at one time. In addition, the first hull 11 and the second hull 12 of the present invention are telescopic. When the first hull 11 and the second hull 12 move away from each other, the distance between the first hull 11 and the second hull 12 becomes larger, which also makes the rescue net 2 further expand. The distance between one side of the rescue net 2 at the lower end of the first hull 11 and the other side of the rescue net 2 at the lower end of the second hull 12 also becomes larger, and more drowning persons can be accommodated. After the first hull 11 and the second hull 12 of the present invention approach each other, the rescue net 2 shrinks accordingly, and the width of the entire hull becomes smaller, facilitating entry into a relatively narrow area to rescue people. In addition, the hull telescopic mechanism 13 in the present invention has a simpler structure compared with the existing telescopic drive unit structure. Through the synchronous drive of the first electric push rod 15, the second electric push rod 16, the first rear electric push rod, and the second rear electric push rod, the first hull 11 and the second hull 12 are driven to approach or move away from each other, with a simple structure and a fast response speed.
