Description

Technical Field

[0001] The present invention relates to the field of surface search and rescue, and more particularly to an unmanned search and rescue vessel. Background Art

[0002] During the search and rescue process at sea, since lifeguards have low swimming speed, limited rescue capabilities, and are greatly affected by wind and waves, water search and rescue boats are mostly used to rescue people who fall into the water.

[0003] Existing water rescue boats are mostly inflatable boats, which are manually driven to the drowning person place for manual rescue. However, the existing rescue boats are relatively small and easily cause the rescue boat to capsize when rescuing in waters with large winds and waves.

[0004] Most existing search and rescue vessels are speedboats, powered by propeller engines installed at the stern. During deployment, a crane is required to place the search and rescue vessel steadily on the water. These vessels are greatly affected by wind and waves, resulting in a slow and dangerous deployment process. Furthermore, propeller engines are likely to cause secondary injuries to people who fall into the water when conducting search and rescue operations in windy and choppy environments.

[0005] Therefore, a new type of search and rescue vessel is needed to solve the above problems. Summary of the Invention

[0006] An object of the present invention is to provide a new technical solution for an unmanned search and rescue vessel.

[0008] Through this solution, the ducted propulsion system can avoid collision damage and injury to people who fall into the water compared to traditional external motors, so that it can be quickly deployed to designated waters for rescue; the double hull structure layout makes the search and rescue ship more stable and suitable for use in strong winds and waves; the pallet, as the main manned tool, is located in the middle, which can keep the center of gravity between the hulls, making it not easy to capsize and ensuring the smooth progress of the rescue.

[0009] Preferably, the hull is a streamlined strip structure, and the ducted propeller is provided at both ends of the hull.

[0010] Through this solution, the strip-shaped structure of the hull reduces resistance; and the ducted thrusters arranged at the front and rear can facilitate the forward and backward movement of the device, greatly improving flexibility and helping to quickly drive the search and rescue ship to the place where people fall into the water for rescue.

[0012] Through this solution, the device can move forward normally regardless of whether it is forward or reverse when entering the water, and can be cast, which greatly improves the efficiency of deployment without the need for a crane to slowly lower it.

[0013] Preferably, the inlet of the ducted propeller is arranged at the top of the bow, and a protective grille is arranged at the inlet.

[0014] Through this solution, the protective grille can prevent aquatic organisms from entering the culvert, thereby playing a protective role, and can also prevent the limbs of people who fall into the water from being sucked in, thereby improving reliability during use.

[0015] Preferably, flexible heating pads are fixed to both the upper and lower sides of the support plate, and the flexible heating pads are electrically connected to the controller.

[0016] Through this solution, the flexible heating pad can keep people who fall into the water warm, avoiding life-threatening dangers caused by low water temperature.

[0017] Preferably, shovel parts are respectively provided on the front and rear sides of the flexible heating pad, and the shovel parts are respectively fixed to the bottom of the two bows, and the shovel parts are smoothly connected to the flexible heating pad.

[0018] Through this solution, the shovel part can be extended below the water surface to conveniently lift up the person who falls into the water, making this device suitable for rescuing unconscious people who fall into the water; the shovel parts on both sides are arranged symmetrically around the center, and can play the role of shoveling under the person who falls into the water and lifting him up regardless of the front or back.

[0019] Preferably, the supporting shovel portion is made of elastic material and has a hollow structure.

[0020] Through this solution, the elastic material can reduce the damage to people who fall into the water, and the hollow structure makes it easier for people who fall into the water to grasp and fix themselves.

[0021] Preferably, cameras are respectively provided at both ends of the hull, and the cameras are electrically connected to the controller.

[0022] Through this solution, during the remote control process, the camera can facilitate the operator to observe the sea surface conditions and accurately rescue people who fall into the water.

[0036] Example

[0037] like Figures 1 to 4 As shown, the unmanned search and rescue ship in this embodiment includes a hull 100 and a pallet 200. The hull 100 is fixed on both sides of the pallet 200. A propulsion mechanism is provided in the hull 100. The propulsion mechanism includes a ducted propeller 310, a power module 320 and a controller 330. The ducted propeller 310 and the power module 320 are both electrically connected to the controller 330.

[0038] Through this solution of the present embodiment, the ducted propeller 310 can avoid collision damage and injury to people who fall into the water compared to the traditional external motor, so that it can be quickly deployed to the designated waters for rescue; the double hull structure arrangement makes the search and rescue ship more stable in operation and suitable for use in strong winds and waves; the pallet 200, as the main manned tool, is located in the middle, which can keep the center of gravity between the hulls 100, making it not easy to capsize, thereby ensuring the smooth progress of the rescue.

[0039] The hull 100 in this embodiment can be a floating structure such as a rubber inflatable structure, a wooden structure, or a plastic material. The two hulls 100 are strip-shaped and arranged in parallel. The support plate 200 is fixed to the opposite side of the hull 100, so that the movement of the hull 100 can drive the support plate 200 to lift the person who falls into the water. In conjunction with the ducted propeller 310, the device can be driven on both sides to achieve a throwing-type deployment. Compared with the traditional crane lowering to the water surface, the deployment efficiency is greatly improved.

[0040] The power module 320 in this embodiment is, for example, a portable battery such as a lithium battery, a lead-acid battery, or a hydrogen fuel cell, and can also be directly connected to the power generation equipment of the mother ship through a wired manner to increase the range and reduce the weight of the hull.

[0041] The controller 330 can be a wireless controller or a wired controller, preferably a wireless controller that can be remotely controlled to control the ducted propeller 310 and the power module 320 to achieve the purpose of driving the device forward and backward, turning left and right, accelerating and decelerating, etc.

[0042] In this or other embodiments, the hull 100 has a streamlined, strip-shaped structure, with the ducted propellers 310 disposed at both ends of the hull 100. The strip-shaped hull 100 reduces resistance; the presence of the ducted propellers 310 at both ends facilitates forward and backward movement of the device, greatly improving flexibility and facilitating rapid navigation of the search and rescue vessel to a person in the water for rescue. Furthermore, the device can be flexibly operated in both forward and reverse directions.

[0043] In this embodiment or other embodiments, the hull 100 includes a hull 110 and bows 120 located on both sides of the hull 110. The bottom of the bow 120 is inclined toward the top of the bow 120. The two bows 120 are arranged in a centrally symmetrical manner. The outlet of the ducted propeller 310 is arranged near the top of the end surface of the bow 120. When entering the water, the device can move forward normally regardless of whether it is facing forward or backward. When the bottom of the bow 120 at one end enters the water, the bow 120 at the other end (i.e., the bow 120 with the top entering the water) can serve as the main propeller to propel the device forward. The arrangement of the bow 120 can improve stability during navigation.

[0044] In this or other embodiments, the inlet of the ducted propeller 310 is located at the top of the bow 120, and a protective grille 130 is disposed at the inlet. The protective grille 130 prevents aquatic organisms from entering the duct, providing protection, and prevents the limbs of people who fall into the water from being sucked in, thereby improving reliability during use.

[0045] In this embodiment or other embodiments, flexible heating pads 210 are fixed to the upper and lower sides of the support plate 200, and the flexible heating pads 210 are electrically connected to the controller 330. The flexible heating pads 210 can keep the person who falls into the water warm and avoid life-threatening danger caused by the low temperature in the water.

[0046] In this embodiment or other embodiments, shovel parts 220 are respectively provided on the front and rear sides of the flexible heating pad 210, and the shovel parts 220 are respectively fixed to the bottom of the two bows 120. The shovel parts 220 are smoothly connected to the flexible heating pad 210 to reduce resistance in water.

[0047] The supporting shovel part 220 can extend below the water surface to conveniently lift up the person who falls into the water, making this device suitable for rescuing unconscious people who fall into the water. Equipped with the setting of the flexible heating pad 210, it can ensure that the person who falls into the water maintains normal vital signs; the supporting shovel parts 220 on both sides are arranged symmetrically around the center, and can play the role of shoveling into the bottom of the person who falls into the water and lifting him up regardless of the front or back.

[0048] In this embodiment or other embodiments, the shovel part 220 is made of elastic material, and the shovel part 220 is a hollow structure. The elastic material is, for example, rubber, which can reduce the damage to the person who falls into the water and improve the comfort of the person who falls into the water during the lifting process. Moreover, the hollow structure makes it convenient for the person who falls into the water to grasp and fix. The hollow structure can also reduce the resistance of the device in the water.

[0049] In this or other embodiments, cameras 340 are provided at each end of the hull 100. These cameras 340 are electrically connected to the controller 330. During remote control, the cameras 340 facilitate observation of sea conditions by the operator, enabling precise rescue of individuals in the water.
