Description

Technical Field

[0001] The present application relates to the field of maritime rescue technology, and in particular to a maritime rescue water-air drone. Background Art

[0002] At present, there are three commonly used methods in the process of rescuing people from falling into the water at sea: Rescuers throw lifebuoys or rescue ropes on shore or on board. This method is limited by factors such as throwing distance, throwing accuracy and water flow. By remotely controlling the lifeboat to reach the drowning person, this method first requires the lifeboat to be put into the water, which is easily affected by the height of the lifeboat and the waves. Secondly, the lifeboat is greatly affected by wind and waves when sailing in the water. It is not suitable when the sea conditions are bad or the distance is too far, and the placement accuracy is not accurate. Using a drone to carry a lifebuoy instead of manually throwing it, this method has errors when the drone flies to the person who falls into the water and drops the lifebuoy, and there is no guarantee that the person who falls into the water will get the lifebuoy. After getting the lifebuoy, the person who falls into the water still needs to wait for rescuers. There are too many uncertainties during the waiting period, which may cause the person who falls into the water to float in the water for a long time. Due to the low water temperature, the person who falls into the water is physically exhausted and falls into the water again, which reduces the efficiency of lifesaving. Summary of the invention

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0019] At present, there are three commonly used methods in the process of rescuing people from falling into the water at sea: (1) Rescuers throw lifebuoys or rescue ropes on shore or on board. This method is limited by factors such as throwing distance, throwing accuracy, and water flow. (2) Remotely control the lifeboat to the person who falls into the water. This method first requires the lifeboat to be put into the water, which is easily affected by the height of the lifeboat and the waves. Secondly, the lifeboat is greatly affected by wind and waves when it is sailing in the water. It is not suitable when the sea conditions are bad or the distance is too far, and the placement accuracy is not accurate. (3) Use drones to carry lifebuoys instead of manually throwing them. This method has errors when the drone flies to the person who falls into the water and drops the lifebuoy. It cannot guarantee that the person who falls into the water will get the lifebuoy. After getting the lifebuoy, the person who falls into the water still needs to wait for rescuers. There are too many uncertainties during the waiting period, which may cause the person who falls into the water to float in the water for a long time. Due to the low water temperature, the person who falls into the water is physically exhausted and falls into the water again, which reduces the efficiency of lifesaving.

[0020] The embodiments of the present application provide a marine rescue water-air drone to solve the problem in related technologies that rescuers on shore or on board are limited by factors such as throwing distance, throwing accuracy and water flow when throwing lifebuoys or rescue ropes, and the problem that the remote-controlled lifeboat is affected by waves when being dropped to the side of a person who falls into the water, resulting in inaccurate placement.

[0021] See also Figure 1-9 , a marine rescue water-air drone, comprising: The drone fuselage 1 has an airbag accommodating chamber at the bottom thereof, and an inflatable assembly and an airbag 2 are arranged in the airbag accommodating chamber; the drone fuselage 1 is provided with a door assembly 3 for opening or closing the airbag accommodating chamber; A plurality of mounting base plates 4 are mounted on the outer peripheral side of the UAV fuselage 1. The bottom of the mounting base plates 4 is rotatably connected to an H-shaped frame 5. A vertical guide tube 6 is arranged inside the H-shaped frame 5. A propeller assembly 7 is coaxially arranged inside the vertical guide tube 6. The H-frame attitude adjustment assembly 8 is arranged corresponding to the H-frame 5 and is installed on the mounting base 4; when in flight, the H-frame attitude adjustment assembly 8 is used to keep the H-frame 5 and the vertical guide tube 6 in a horizontal state; when moving on the sea surface, the H-frame attitude adjustment assembly 8 is used to keep the H-frame 5 and the vertical guide tube 6 in a vertical state so as to contact with the sea water and generate propulsion.

[0022] The above fuselage can be used as a temporary life-saving device on the sea surface in conjunction with the airbag. Since it can fly to the person to be rescued, it is not limited by distance. On the sea surface, the propeller assembly 7 that originally provides flight power is used as a propeller reward. The drone can move on the sea surface and can be accurately deployed, realizing dual-purpose use in water and air.

[0023] Among them, the H-frame attitude adjustment component 8 is used to change the rotation direction of the propeller blades, as well as the number, location, and speed of the running propellers, so as to control the propulsion direction, so as to realize water and air dual-use, and perform search and rescue. Taking the four propeller assemblies 7 as an example, when they are all in a vertical state, when moving forward, the two propeller assemblies 7 at the front are in forward rotation, and the two propeller assemblies 7 at the rear are in reverse rotation; when moving backward, the two propeller assemblies 7 at the front are in reverse rotation, and the two propeller assemblies 7 at the rear are in forward rotation; when moving to the left, the two propeller assemblies 7 at the left are in forward rotation, and the two propeller assemblies 7 at the right are in reverse rotation; when moving to the right, the two propeller assemblies 7 at the left are in reverse rotation, and the two propeller assemblies 7 at the right are in forward rotation; when turning, such as turning right, the rotation speed of the propeller assembly 7 on the right is less than that of the propeller assembly 7 on the left.

[0024] When the UAV lands on the water, the hatch assembly 3 opens and releases the airbag 2, which cooperates with the original cavity to provide sufficient buoyancy for rescue and ensure that the UAV can withstand the gravity of the person who falls into the water; the hatch at the bottom of the UAV after opening can act as a bilge keel, thereby reducing the roll of the UAV and ensuring its stability in severe sea conditions; in addition, when personnel are on the UAV fuselage 1, the posture of the propeller assembly 7 can be adjusted again to transport personnel by air and speed up the rescue.

[0025] In some preferred embodiments, the mounting substrate 4 is an L-shaped plate 401, and a sleeve 400 is provided at the bottom of the vertical portion of the L-shaped plate 401; The H-shaped frame 5 includes a first rod 500, and the two ends of the first rod 500 are perpendicularly connected to the second rod 501. The first rod 500 is a round rod, and the cross-section of the second rod 501 is a rectangle. The first rod 500 passes through the sleeve 400 and is rotatably connected to the sleeve 400. The ends of the two second rods 501 away from the drone fuselage 1 are fixedly connected to the vertical guide tube 6. The central axis of the vertical guide tube 6 is perpendicular to the plane where the H-shaped frame 5 is located.

[0026] The L-shaped plate 401 is fixedly connected to the drone body 1 via a connecting seat 402, and a rotation space is provided in the connecting seat 402; The H-frame posture adjustment assembly 8 includes a rotating rod 800 located at the bottom of the H-frame 5, a baffle 801 is fixedly connected to the rotating rod 800, the rotating rod 800 passes through a rotating space, and the baffle 801 is located in the rotating space; the baffle 801 includes a cylindrical portion fixedly connected to the rotating rod 800, a rectangular portion is provided on the cylindrical portion, the length of the rectangular portion is parallel to the axial direction of the first rod 500, and the two ends of the rectangular portion in the length direction are respectively in contact with the bottom of the second rod 501; the width of the rectangular portion is parallel to the axial direction of the second rod 501; in the width direction of the rectangular portion, the width of the overlapping portion of the second rod 501 and the rectangular portion is equal to the width of the rectangular portion; a pressure sensor is provided on the side of the rectangular portion that contacts the H-frame 5; The rotating rod 800 is connected to a stepping motor 802 ; the stepping motor 802 is mounted on the mounting substrate 4 .

[0027] For the above structure, please refer to the attached Figure 1 -Attached Figure 4 , the structure of the H-frame attitude adjustment assembly 8 is introduced in detail. In the flight state, the baffle 801 supports the H-frame 5 and limits its downward movement. Since the cross-section of the second rod 501 is rectangular, when subjected to an upward force, it resists against the baffle 801 and will not move upward. In addition, due to the special structure of the H-frame 5, the H-frame 5 is rotatably connected to the sleeve 400 through the first rod 500, and the first rod 500 is located in the middle of the second rod 501; in this way, when subjected to an upward force, the end of the second rod 501 close to the connecting seat 402 presses the baffle 801 downward, the baffle 801 is in a locked state, and the second rod 501 will not move; in this way, when subjected to a downward force, the end of the second rod 501 away from the connecting seat 402 presses the baffle 801 downward, the baffle 801 is in a locked state, and the second rod 501 will not move; similar to the structure of the seesaw board, both ends of the seesaw board are limited, and the two ends are located in the same horizontal plane, so it will not move at this time.

[0028] refer to Figure 8 and Fig. 9When the propeller assembly 7 needs to be adjusted in posture, the stepper motor 802 is used to drive the baffle 801 from horizontal to vertical, without bearing the H-frame 5. The H-frame 5, the vertical guide tube 6 and the propeller assembly 7 become vertical under the action of their own gravity. However, since the baffle is used as a critical limit of the maximum rotation position at this time, it is used as a limit at this time.

[0029] However, there is a problem that the H-shaped frame 5 swings left and right, so a telescopic limiter 9 is further provided at the bottom of the vertical portion of the L-shaped plate 401, and the telescopic limiter 9 includes an electric telescopic rod. When the H-shaped frame 5 falls, the telescopic limiter 9 extends vertically, thereby preventing the H-shaped frame 5 from swinging left and right.

[0030] Furthermore, in order to timely determine whether the H-frame 5, the vertical guide tube 6 and the propeller assembly 7 have become vertical under the action of their own gravity, a pressure sensor can be provided on the baffle 801 for detection and judgment. That is to say, when the baffle 801 receives the designed pressure in the vertical state, the telescopic limit member 9 extends vertically.

[0031] In some preferred embodiments, the door assembly 3 includes a door 300 and a telescopic diagonal brace member 301, and the door 300 and the drone fuselage 1 are connected via an elastic rubber plate; One end of the telescopic diagonal brace rod 301 is hinged to the door 300 , and the other end is hinged to the inner top of the airbag accommodating chamber.

[0032] The above elastic rubber plate is used to connect the door 300 and the drone body 1, which does not require an extra hinge structure and reduces costs. The telescopic diagonal support rod 301 includes an inclined gas rod and an electric telescopic rod.

[0033] Among them, the airbag accommodation compartment has the above two forms: One is: The number of the airbag accommodating compartment is one, and the number of the doors 300 is two. The two doors 300 are used to close the airbag accommodating compartment, and are respectively connected to a corresponding telescopic diagonal bracing rod 301.

[0034] Another is: There are two airbag accommodating chambers, which are symmetrically arranged about the main axis of the drone body 1; one telescopic diagonal brace rod 301 corresponds to one hatch 300. This can achieve two cabins symmetrically arranged about the center line at the bottom of the drone, with the hatch facing downward. The cabin contains airbags 2, which are inflated by the internal air pump. When the drone lands on the water, the hatch opens and releases the airbags, which cooperate with the original cavity to provide sufficient buoyancy for rescue and ensure that the drone can withstand the gravity of the drowning person; the hatches on both sides of the bottom of the drone can act as bilge keels after opening, thereby reducing the roll of the drone and ensuring its stability in severe sea conditions.

[0035] In some preferred embodiments, a handle 10 is provided on the top of the drone body 1, and the handle 10 facilitates personnel to reach the drone body 1 from the sea.

[0036] In some preferred embodiments, the drone body 1 is provided with a remote camera, an emergency rescue light, and a GPS module. Remote camera and GPS module. A camera unit is installed at the front of the drone. The remote camera can rotate within a certain range. When flying, the remote camera looks down to facilitate search and rescue. When sailing in the water, the remote camera cooperates with the GPS module and the signal transmitter to not only identify the direction and record the rescue scene in real time, but also to timely observe the life characteristics of the people who fell into the water and communicate remotely. At the same time, the camera is equipped with infrared and lighting, which is more convenient for night search and rescue. The emergency rescue light can be used for warning.

[0037] In summary, the airbag compartment is set inside the main body of the drone, which can reduce the overall weight of the drone and improve its endurance, and provide sufficient buoyancy for the drone itself in the water. Four vertical guide tubes 6, the propeller assembly 7 includes a ducted propeller and a waterproof brushless motor, each motor can operate independently, and can be used not only when flying in the air, but also in the water. When flying in the air, the propeller faces upward to provide vertical upward lift. When sailing on the water surface, the propeller dives below the water surface and faces forward, acting as an underwater propeller; the drone body 1 is streamlined as a whole to reduce navigation resistance. Two airbag accommodating compartments are symmetrically arranged twice at the bottom of the fuselage, and airbags are installed inside. When the drone lands on the water surface, it first floats by its own buoyancy, and then the two bottom side doors are opened, and the airbags are ejected and inflated by the air pump of the internal inflation assembly to provide greater buoyancy for the drone. At the same time, the opened doors act as bilge keels, which are beneficial to lateral stability and reduce roll when sailing in the water; two handles 10 with different spacings are symmetrically distributed on both sides of the drone body, which can be held by hand or tied with a rescue rope for the convenience of people who fall into the water; A remote camera is installed on the front of the drone, which can rotate within a certain range. When flying, the remote camera looks down to facilitate search and rescue. When sailing in the water, the camera cooperates with the signal transmitter to not only identify the direction and record the rescue scene in real time, but also observe the life characteristics of the people who fall into the water and communicate remotely. At the same time, the remote camera is equipped with infrared and lighting, which is more convenient for search and rescue and can also be used at night. All circuit modules of the drone are installed and sealed in the shell. On the one hand, it simplifies the structure and reserves enough volume for the cavity to meet the buoyancy requirements. On the other hand, it facilitates wiring, improves the electrical waterproof function, and ensures the circuit safety of the drone.

[0038] Working principle: When a person is found falling into the water, the rescuers can immediately open the rescue drone, remotely control the drone to fly over the water where the person fell into the water, and then control the drone to land on the water. First, the drone floats by relying on the buoyancy of its own cavity, and then controls the two hatches at the bottom of the fuselage to open, and the inflation component inflates the airbag inside, and the airbag expands to provide it with greater buoyancy.

[0039] While the airbag is deployed, the H-frame attitude adjustment assembly 8 rotates the propeller from vertically upward to horizontally forward and submerges it in the water, controlling the drone to quickly approach the person who falls into the water. When the drone approaches the person who falls into the water, the person grabs the handle, lies on the upper surface of the drone, and holds the handle with both hands, and then the rescuer controls the drone to return to the water surface. During the rescue process, the drone can take off and land on the water surface twice as needed until it flies to the person who falls into the water.

[0040] Drone rescue is not limited by the height of entry into the water and the sea conditions. Compared with flying in the water, the air is faster and the search and rescue range and field of view are wider. This search and rescue drone is not only suitable for search and rescue in near-shore waters, but also for ocean-going ship rescue at sea. It not only shortens the rescue time, but also improves the search and rescue efficiency, thereby increasing the survival rate of people who fall into the water. It provides guarantees for rescue work, thereby achieving more efficient and reliable search and rescue results at sea.
