Description

Technical Field

[0001] The present invention relates to the technical field of marine unmanned aerial vehicles (UAVs), and in particular to a UAV for marine rescue. Background Art

[0002] With the increasing frequency of global marine activities and the growing demand for maritime rescue, marine drones, as an emerging rescue tool, are gradually gaining attention due to their unique advantages. First, marine drones have the ability to fly high, reach long distances, and quickly reach the scene, allowing them to quickly locate rescue targets.

[0003] Current marine drones typically use ropes to suspend single or multiple lifebuoys when deploying rescue equipment. While this method is simple, it has numerous drawbacks in practical application. First, using ropes to suspend multiple lifebuoys can significantly impact the drone's flight stability. As the number of lifebuoys mounted increases, the drone's center of gravity distribution shifts, making flight control difficult and increasing the risk of accidents. Second, the rope-suspended method cannot achieve separate deployment to multiple targets. Rescue missions often require simultaneous or sequential rescue of multiple targets, but existing drone deployment methods typically only release all lifebuoys at once, failing to precisely target each target. Furthermore, drones can deliver more than just lifebuoys; rescue operations also require the delivery of food, medicine, and various other rescue equipment. If drones can only deliver lifebuoys, their applicability is limited, impacting rescue efficiency. Summary of the Invention

[0004] In view of the problems that the above-mentioned existing rescue drones will affect their flight stability when carrying lifebuoys, the rescue drones cannot drop multiple lifebuoys simultaneously, and the drones cannot drop other rescue equipment during the rescue process, the present invention is proposed.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a marine rescue drone, comprising a drone body, a drone frame fixedly mounted on the bottom of the drone body, a rescue box fixedly mounted on the inner surface of the drone frame via bolts, a delivery mechanism fixedly mounted in the inner cavity of the rescue box, an inflation mechanism fixedly mounted on the inner wall of the rescue box, and a balancing brake mechanism fixedly mounted on the inner surface of the rescue box; The delivery mechanism includes a carrying component arranged on the inner wall of the rescue box, and the carrying component includes a delivery rack arranged on the inner wall of the rescue box. A delivery plate is slidably installed on the inner surface of the delivery rack, a carrying box is fixedly installed on the bottom of the delivery plate, and a fixing bolt is fixedly installed on the top of the carrying box. The top of the fixing bolt passes through the delivery plate and extends to the outside of the delivery plate. A nut is threaded on the outer surface of the fixing bolt, and a fixing block is fixedly installed on the top of the delivery plate.

[0006] As a preferred solution of the marine rescue drone described in the present invention, the launching mechanism also includes a fixing component arranged on the inner wall of the rescue box, the fixing component includes a No. 1 fixing frame arranged on the inner wall of the rescue box, a No. 1 motor is fixedly installed on the left side of the No. 1 fixing frame, a No. 1 rotating shaft is fixedly installed on the output end of the No. 1 motor through a reducer, and a worm is fixedly installed on the left end of the No. 1 rotating shaft.

[0007] As a preferred solution of the marine rescue drone described in the present invention, the fixing assembly further includes a No. 2 fixing bracket arranged on the inner wall of the rescue box, a threaded rod is rotatably mounted on the bottom of the No. 2 fixing bracket, and a worm gear is fixedly mounted on the outer surface of the threaded rod.

[0008] As a preferred solution of the marine rescue drone of the present invention, the outer surface of the worm is mixed with the outer surface of the worm wheel, and the outer surface of the worm is threadedly connected to the inner surface of the fixing block.

[0009] As a preferred solution of the marine rescue drone of the present invention, the inflation mechanism includes a connecting frame arranged on the inner wall of the rescue box, a branch pipe is fixedly installed on the inner surface of the connecting frame, and a valve is fixedly installed on the outer surface of the branch pipe.

[0010] As a preferred solution of the marine rescue drone of the present invention, a sliding pipe is slidably mounted on the inner surface of the branch pipe, an air injection pipe is snap-fitted onto the outer surface of the sliding pipe, and the top end of the branch pipe is connected to the main pipe.

[0011] As a preferred solution of the marine rescue drone described in the present invention, the inflation mechanism also includes a placement plate arranged on the inner wall of the rescue box, an air pump is fixedly installed on the top of the placement plate, and the output end on the right side of the air pump is connected to the left end of the main pipe.

[0012] As a preferred solution of the marine rescue drone described in the present invention, the balancing brake mechanism includes a slide arranged on the inner wall of the rescue box, a slide groove is provided on the back of the slide, a No. 2 motor is fixedly installed on the left side of the slide, and a threaded shaft is fixedly installed on the output end of the No. 2 motor through a reducer, a counterweight block is threadedly installed on the outer surface of the threaded shaft, and the outer surface of the counterweight block is slidably connected to the inner surface of the slide groove.

[0013] Beneficial effects of the present invention: 1. The present invention adds a design that enables the drone to drop rescue supplies separately. By using a No. 1 motor and a No. 1 rotating shaft in conjunction with a worm and a worm gear, and using the worm gear and threaded rod in conjunction with a fixed block and a drop plate, and using the drop plate in conjunction with a carrying box, the lifebuoy or rescue supplies stored in the carrying box can be dropped separately, thereby avoiding the drone being unable to drop lifebuoys to multiple targets separately, which would reduce the efficiency of the drone's drop.

[0014] 2. The present invention adds a design for the drone to carry a compressed lifebuoy for rescue. By using an air pump and a main pipe in conjunction with a branch pipe and a valve, and by using the branch pipe and a sliding pipe in conjunction with an air injection pipe and a carrying box, the compressed lifebuoy in the carrying box can be inflated. When the drone does not need to carry the lifebuoy with a rope, the lifebuoy will not swing back and forth, affecting the flight stability of the drone, thereby improving the safety of the drone during flight.

[0015] 3. The present invention adds a design to maintain the internal weight balance of the drone when dropping supplies. By using the No. 2 motor and the threaded shaft in conjunction with the counterweight and the slide, and the counterweight in conjunction with the rescue box and the drone body, the center of gravity of the rescue box can be adjusted in time for balance after the supplies are dropped into the rescue box, thereby avoiding the problem that the center of gravity of the drone is low after the drone drops some supplies, which increases the risk of the drone flying.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1-6 The first embodiment of the present invention provides a marine rescue drone, comprising a drone body 1, a drone frame 2 fixedly mounted on the bottom of the drone body 1, a rescue box 4 fixedly mounted on the inner surface of the drone frame 2 via bolts 3, a delivery mechanism 5 fixedly mounted within the inner cavity of the rescue box 4, an inflation mechanism 6 fixedly mounted on the inner wall of the rescue box 4, and a balancing brake mechanism 7 fixedly mounted on the inner surface of the rescue box 4; The delivery mechanism 5 includes a carrying component 51 arranged on the inner wall of the rescue box 4, and the carrying component 51 includes a delivery rack 511 arranged on the inner wall of the rescue box 4. A delivery plate 512 is slidably installed on the inner surface of the delivery rack 511, and a carrying box 513 is fixedly installed on the bottom of the delivery plate 512. A fixing bolt 514 is fixedly installed on the top of the carrying box 513. The top of the fixing bolt 514 passes through the delivery plate 512 and extends to the outside of the delivery plate 512. A nut 515 is threadedly installed on the outer surface of the fixing bolt 514, and a fixing block 516 is fixedly installed on the top of the delivery plate 512.

[0024] The delivery mechanism 5 also includes a fixing assembly 52 arranged on the inner wall of the rescue box 4. The fixing assembly 52 includes a No. 1 fixing frame 521 arranged on the inner wall of the rescue box 4. A No. 1 motor 522 is fixedly installed on the left side of the No. 1 fixing frame 521. The output end of the No. 1 motor 522 is fixedly installed with a No. 1 rotating shaft 523 through a reducer. A worm 524 is fixedly installed on the left end of the No. 1 rotating shaft 523.

[0025] The first motor 522 is electrically connected to an external power source and is controlled by an external PLC programming program.

[0026] The fixing assembly 52 further includes a second fixing bracket 525 disposed on the inner wall of the rescue box 4 . A threaded rod 526 is rotatably mounted on the bottom of the second fixing bracket 525 , and a worm gear 527 is fixedly mounted on the outer surface of the threaded rod 526 .

[0027] The outer surface of the worm 524 is interlocked with the outer surface of the worm wheel 527 , and the outer surface of the worm 524 is threadedly connected to the inner surface of the fixing block 516 .

[0028] During use, the user first puts the rescue materials or compressed lifebuoy to be released into the carrying box 513. When the carrying box 513 contains the lifebuoy, the user draws the air injection pipe 65 of the lifebuoy out of the carrying box 513, and then inserts the carrying box 513 into the delivery rack 511 from the bottom of the rescue box 4. Then, the No. 1 rotating shaft 523 is driven to rotate by the No. 1 motor 522, and the No. 1 rotating shaft 523 drives the worm gear 527 to rotate through the worm gear 524. The worm gear 527 drives the fixed block 516 to move upward through the threaded rod 526, and fixes the delivery plate 512 carrying the fixed block 516 in the delivery rack 511, and at the same time inserts the sliding tube 64 into the air injection pipe 65 of the compressed lifebuoy. When the rescue drone moves to the rescue sea surface, the No. 1 motor 522 reverses and drives the carrying box 513 carrying the compressed lifebuoy to move downward in the delivery rack 511.

[0033] The air pump 68 is controlled by an external PLC programming program and is electrically connected to an external power supply.

[0034] During use, when the carrying box 513 carrying the compressed lifebuoy moves downward in the delivery rack 511, the sliding pipe 64 moves downward together, and at the same time the air pump 68 injects external air into the main pipe 66, and then the valve 63 of the branch pipe 62 above the compressed lifebuoy delivery portion is opened, so that the gas in the main pipe 66 can be injected into the branch pipe 62, and then the gas is injected from the branch pipe 62 into the gas injection pipe 65 connected to the sliding pipe 64, and the gas is injected into the compressed lifebuoy, so that the compressed lifebuoy is inflated and moves out from the bottom of the delivery rack 511. When the lifebuoy is inflated, the No. 1 motor 522 continues to drive the No. 1 rotating shaft 523 to rotate, so that the fixed block 516 is disengaged from the threaded connection with the threaded rod 526, so that the delivery plate 512 carrying the inflated lifebuoy is delivered from the rescue box 4, so that the people below can get the inflated lifebuoy and carry out self-rescue.

[0035] Reference Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the first embodiment in that: the balancing brake mechanism 7 includes a slide 71 arranged on the inner wall of the rescue box 4, and a slide groove 72 is provided on the back of the slide 71. A second motor 73 is fixedly installed on the left side of the slide 71. The output end of the second motor 73 is fixedly installed with a threaded shaft 74 through a reducer. The outer surface of the threaded shaft 74 is threadedly mounted with a counterweight block 75, and the outer surface of the counterweight block 75 is slidably connected to the inner surface of the slide groove 72.

[0036] The second motor 73 is electrically connected to an external power source and is controlled by an external PLC programming program.

[0037] During use, when the carrying box 513 in the rescue box 4 is thrown out, the second motor 73 drives the threaded shaft 74 to rotate, and the threaded shaft 74 drives the counterweight block 75 to move on the slide 71 to balance the weight in the rescue box 4.

[0038] The remaining structures are the same as those of Example 1.
