Description

Technical Field

[0001] This invention relates to the field of maritime search and rescue systems, specifically to a drone search and rescue system that can be rapidly deployed on the water surface. Background Technology

[0002] Currently, maritime search and rescue mainly relies on aircraft such as helicopters and fixed-wing drones. For long-distance maritime search and rescue missions, the flight speed is limited, requiring hours to reach the search area, making it difficult to provide timely rescue. Therefore, there is a need to develop a drone search and rescue system that can be quickly deployed on the sea surface and can reach a search area hundreds of kilometers away within minutes, capable of independently completing a search of hundreds of square kilometers of sea area and providing emergency supplies.

[0003] Patent document CN205168851U discloses a UAV-based maritime search and rescue system. This system includes a helicopter, a UAV mounted on the helicopter, and a rescue device mounted on the helicopter. When the system is activated, the UAV connects to the helicopter via a wireless communication network. The UAV searches for and locates a person in the water according to a preset search area and route, and promptly transmits the person's location information to the rescue device. The rescue device then uses this location information to rescue the person. This invention shortens the search time for locating a person in the water by applying UAV technology to the maritime search and rescue system. However, this solution cannot achieve rapid deployment on the water surface and cannot independently complete a search of an area of ​​several hundred square kilometers. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of this invention is to provide a drone search and rescue system that can be rapidly deployed on water.

[0005] The unmanned aerial vehicle (UAV) search and rescue system that can be rapidly deployed on water surface according to the present invention includes a delivery unit and a UAV formation. The delivery unit includes a UAV platform section, an airbag platform section and a booster section connected in sequence from front to back. The UAV formation is located inside the UAV platform section.

[0006] The airbag platform section is equipped with an airbag assembly inside. The drone platform section includes a deployable flap assembly. When the drone search and rescue system is in launch or flight mode, the airbag assembly is not inflated and the flap assembly is in a closed state. The drone formation is located inside the flap assembly.

[0007] When the UAV search and rescue system is in a non-deployed state on the water surface, the airbag assembly inflates to form a floating plane, and the delivery device floats on the water surface through the floating plane. At this time, the compartment assembly is in a closed state.

[0008] When the UAV search and rescue system is deployed on the water, the compartment assembly unfolds, so that the multiple compartments of the compartment assembly are horizontally arranged on the airbag assembly, and the UAV formation is mounted on the horizontally arranged compartments.

[0009] Preferably, the internal structure of the flap assembly is equipped with an electrical system and communication equipment, and the communication equipment is coaxially connected to the airbag platform section.

[0010] The electrical system comprises multiple systems, each of which is located on the top of a multiple compartment and is electrically connected to the drone formation on the corresponding compartment.

[0011] Preferably, the interior of the airbag platform section is also equipped with a high-pressure gas cylinder, a controller, and a valve. The high-pressure gas cylinder is located at the tail end of the airbag assembly and is connected to the airbag assembly through the valve. The controller is connected to the valve.

[0012] Preferably, the booster section includes a booster section body, wings, rudders, and a rocket engine. The rocket engine is located at the tail of the booster section body, and the wings and rudders are both located on the outer side of the booster section body.

[0013] Preferably, the rocket engine includes a solid rocket engine.

[0014] Preferably, the airbag assembly includes multiple airbags, which are arranged circumferentially along the high-pressure gas cylinder and are individually connected to the high-pressure gas cylinder through valves.

[0015] Preferably, when the UAV search and rescue system is deployed on the water surface, the compartments are each positioned on the airbag.

[0016] Preferably, the drone formation includes several drones, each drone having a payload mounted on its top.

[0017] Preferably, the drone includes a detection drone and a rescue drone. The payload of the detection drone includes optical detection equipment and radar, and the payload of the rescue drone includes portable life jackets and medical supplies.

[0018] Preferably, both the detection drone and the rescue drone are quadcopter drones.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention has a simple structure and is easy to operate. By setting up an airbag assembly to form a floating plane, it can be quickly deployed on the water surface, thus enabling it to independently complete search and rescue operations in a sea area of ​​hundreds of square kilometers.

[0021] 2. This invention employs a hybrid technology of detection-type UAVs and rescue-type UAVs, enabling it to provide emergency supplies for rescue immediately upon target discovery during sea area searches. Attached Figure Description

[0041] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0042] This invention discloses a drone search and rescue system that can be rapidly deployed on the sea surface. It can be deployed quickly on the sea surface and reach a search and rescue area hundreds of kilometers away within minutes. It can independently complete a sea area search within hundreds of square kilometers and provide emergency supplies.

[0043] The unmanned aerial vehicle (UAV) search and rescue system that can be rapidly deployed on water, as provided by the present invention, such as Figure 1-9 As shown, it includes a delivery unit and a drone formation 5. The delivery unit includes a drone platform section 1, an airbag platform section 2 and a booster section 3 connected in sequence from front to back. The drone formation 5 is located inside the drone platform section 1.

[0044] like Figure 3 As shown, the airbag platform section 2 is internally equipped with an airbag assembly 6, and the UAV platform section 1 includes a deployable flap assembly. When the UAV search and rescue system is in launch or flight mode, the airbag assembly 6 is not inflated and the flap assembly is in a closed state, with the UAV formation 5 located inside the flap assembly. When the UAV search and rescue system is in a closed state on the water surface, the airbag assembly 6 inflates to form a floating plane, and the delivery device floats on the water surface through the floating plane, with the flap assembly in a closed state. When the UAV search and rescue system is in a deployed state on the water surface, the flap assembly deploys, so that the multiple flaps 10 of the flap assembly are horizontally arranged on the airbag assembly 6, with the UAV formation 5 mounted on the horizontally arranged flaps 10.

[0045] like Figure 3-5 As shown, the interior of the compartment assembly is equipped with an electrical system 4 and a communication device 11. The communication device 11 is coaxially connected to the airbag platform section 2. There are multiple electrical systems 4, which are respectively installed on the top of multiple compartments 10 and are all electrically connected to the drone formation 5 on the corresponding compartment 10.

[0046] like Figure 6As shown, the airbag platform section 2 is also equipped with a high-pressure gas cylinder 7, a controller 12, and a valve 13. The high-pressure gas cylinder 7 is located at the tail end of the airbag assembly 6 and is connected to the airbag assembly 6 via the valve 13. The controller 12 is connected to the valve 13. The airbag assembly 6 includes multiple airbags, which are arranged circumferentially along the high-pressure gas cylinder 7 and are individually connected to the high-pressure gas cylinder 7 via the valve 13. When the UAV search and rescue system is deployed on the water surface, the compartment petals 10 are positioned one-to-one on the airbags. The controller 12 controls the high-pressure gas cylinder 7 to inflate the airbag assembly 6 via the valve 13, ensuring that the air pressure inside the airbag assembly 6 is maintained within the required range so that it can float on the sea surface.

[0047] like Figure 7 As shown, the booster stage 3 includes a booster stage body, wings 8, rudders 9, and a rocket engine 14. The rocket engine 14 is located at the tail of the booster stage body, and the wings 8 and rudders 9 are both located on the outer side of the booster stage body. Preferably, the rocket engine 14 is a solid rocket engine, which has a simple and reliable structure, and the UAV search and rescue system can be used multiple times by replacing the solid rocket engine.

[0048] like Figure 8 As shown, the drone formation 5 comprises several drones, each with a payload 15 mounted on its top. The drones include reconnaissance drones and rescue drones, both using a common platform. The payload 15 carried by the reconnaissance drones includes optical detection equipment and radar, while the payload 15 carried by the rescue drones includes portable life jackets and medical supplies. Both reconnaissance and rescue drones are quadcopter drones. The drones can take off, land, and be wirelessly charged on the cabin flap 10. Multiple formations of reconnaissance and rescue drones can be formed, with these formations taking off alternately for reconnaissance. The drone formations can be divided into multiple groups, each carrying out missions simultaneously along different paths, using a mixed formation of the two types of drones.

[0049] In a preferred embodiment of the present invention, there are a total of 20 drones, 8 of which are reconnaissance drones and 12 of which are rescue drones. Each mission is carried out by a group of "2 reconnaissance drones + 3 rescue drones". The two groups are always in a state of going out for search and rescue and the two groups are docked on the cabin petals for wireless charging. If a rescue target is found, all of them will take off to provide maximum rescue capability.

[0050] like Figure 9As shown, the specific working process of this invention is as follows: the drone formation 5 is delivered to the search and rescue area via a delivery unit. The delivery unit is powered by a rocket engine 14, thus enabling it to quickly reach a distant destination. After the delivery unit arrives at the target waters, the airbag assembly 6 is inflated and deployed by the high-pressure gas cylinder 7. The delivery unit stands upright on the sea surface with the airbag assembly 6 in place, and the drone platform section 1 faces upwards. Then, the drone platform section unfolds in a petal-like manner. The drones can take off, stop, and recharge on the drone platform petals 10. Multiple formations of reconnaissance drones and rescue drones are formed, and these formations take off alternately for reconnaissance. After completing the rescue mission, the search and rescue system can be recovered and reused after replacing the solid rocket engine 14.
