Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) patrol technology, and in particular to a UAV patrol monitoring and alarm device for marine protection. Background Technology

[0002] With the rapid development of the marine economy, marine ecological environment protection faces increasingly severe challenges, with frequent occurrences of illegal fishing, illegal sewage discharge, and ecological damage caused by nearshore engineering projects. Traditional marine monitoring and protection methods mainly rely on patrols by marine surveillance vessels and shore-based radar monitoring, which have inherent drawbacks such as high operating costs, limited coverage, slow response speed, and great susceptibility to sea conditions and weather. They are difficult to achieve routine and timely monitoring of vast sea areas, especially remote ecological protection areas. The introduction of drone technology has provided a new solution for marine monitoring. Currently, there are some applications using drones for surface environment monitoring, such as using drones equipped with high-definition cameras, multispectral imagers, and other sensors to achieve surface monitoring of sea areas.

[0003] The prior art discloses a surface environment monitoring and patrol drone with announcement number CN214057847U; the device monitors the environment in which the surface environment monitoring and patrol drone flies through an environmental detection system, and the captured images and detected flight environment data are stored in the storage module through the main control module; when the surface environment monitoring and patrol drone falls into the water, the waterproof structure can make the surface environment monitoring and patrol drone float, thereby facilitating retrieval.

[0004] The aforementioned existing patents still have the following problems: However, when the drone falls into the water, the device detonates a detonator via a water-triggered electrode, activating the propellant and triggering the airbag to deploy, making the drone float on the water surface for subsequent salvage. The airbags used in this process deploy by bursting, making them disposable inflation devices with significant drawbacks such as low safety, insufficient reliability, and inability to be reused. Furthermore, the landing gear structure at the bottom of the drone disrupts its aerodynamic shape during flight, increasing drag and thus affecting the overall flight performance and operational stability. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing a drone patrol monitoring and alarm device for marine protection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A drone patrol monitoring and alarm device for marine protection includes a drone body. An upper compartment is fixed to the bottom of the drone body, and a lower compartment is fixed to the bottom of the upper compartment. The upper compartment contains an alarm structure for monitoring and alarming. The lower compartment contains an anti-sinking structure to facilitate the salvage and recovery of the drone body. The anti-sinking structure includes a mounting groove on the top surface of the lower compartment. Two unfolding plates are slidably arranged inside the mounting groove. Movable slots are formed on the sides of the two unfolding plates that are close to each other. Fixed seats are fixed inside each of the two movable slots. Two connecting rods are arranged between the two movable slots, with one end of each connecting rod rotatably connected to the two fixed seats. A connecting plate is arranged between the two movable slots, with the other ends of the two connecting rods rotatably connected to the connecting plate. An electric actuator is fixed to one side of the inner wall of the mounting groove, and the telescopic end of the electric actuator is fixed to one side of the connecting plate. Several fixed slots are formed on the bottom surface of the lower compartment, and a first float is fixed inside each of the several fixed slots.

[0007] In the aforementioned UAV patrol monitoring and alarm device for marine protection, the bottom surface of the lower compartment is provided with a retraction slot. Inside the retraction slot are two U-shaped tripods, corresponding to the shape of the retraction slot. The inner wall of the retraction slot is provided with a rotating groove. A rotating shaft is fixed to one side of each of the two tripods, passing through the tripods. The two ends of the rotating shaft are respectively rotatably connected to the interior of the corresponding rotating groove. Both ends of the rotating shaft are wound with torsion springs. One end of the torsion spring is fixed to the rotating groove, and the other end of the torsion spring is fixed to the rotating shaft. A gear is fixed to one end of each rotating shaft. The bottom surface of the mounting slot is provided with two movable holes, which communicate with the rotating groove. A rack is slidably installed inside each of the two movable holes. The rack is L-shaped, and the two racks are respectively fixed to the bottom surface of the two unfolding plates.

[0008] In the above-mentioned drone patrol monitoring and alarm device for marine protection, the alarm structure includes a sealed cavity opened inside the upper cabin, a controller fixed inside the sealed cavity, an accelerometer fixed inside the sealed cavity, and an audible and visual alarm and a buzzer fixed on one side of the upper cabin.

[0009] In the above-mentioned drone patrol monitoring and alarm device for marine protection, T-shaped blocks are fixed to the inner wall of the mounting slot, T-shaped grooves are opened on both sides of the two unfolding plates, the T-shaped blocks and the interior of the T-shaped grooves are slidably arranged, and a second float plate is fixed to the bottom surface of the two unfolding plates.

[0010] In the aforementioned drone patrol monitoring and alarm device for marine protection, a magnetic plate is fixed inside the deployment and retraction slot, and the magnetic plate is magnetically connected to the two tripods.

[0011] In the aforementioned drone patrol monitoring and alarm device for marine protection, the tripod is a hollow structure with several connection holes on one side.

[0012] In the aforementioned drone patrol monitoring and alarm device for marine protection, a fixed cavity is provided inside the upper cabin, and a third float is fixed inside the fixed cavity.

[0013] In the aforementioned drone patrol monitoring and alarm device for marine protection, a reflective warning tape is fixed to one side of the tripod.

[0014] Compared with existing technologies, the advantages of this invention are: It has achieved intelligent linkage between marine monitoring and early warning and on-site law enforcement. By integrating an accelerometer, audible and visual alarm and buzzer through the airborne controller, it can automatically identify illegal behavior or crash status and actively issue warnings, which significantly improves law enforcement response speed and operational efficiency. An innovative retractable anti-sinking and stable floating structure was designed. The deployment plate and linkage mechanism are driven by electric actuators, which simultaneously drive rack and gear transmission to realize the automatic retraction of the tripod and the deployment of the floating plate. This not only solves the aerodynamic and fluid resistance problems of the protruding structure, but also provides a highly reliable anti-sinking guarantee through the coordinated use of multiple floating plates, the first floating plate, the second floating plate, and the third floating plate. The structure is reusable and has no risk of explosion. The overall structure and functional design have been optimized. T-slots and T-blocks are used to guide the equipment to ensure smooth deployment. Magnetic plates enable reliable storage of the tripod. Reflective warning tapes and hollow tripod designs further improve the visibility of the equipment during retrieval and reduce the weight of the structure, thus enhancing the equipment's practicality and environmental adaptability. In summary, this invention, through intelligent sensing, electromechanical linkage, and structural innovation, forms a complete technical solution integrating cruise monitoring, active alarm, autonomous anti-sinking, and efficient recovery. It effectively overcomes the shortcomings of existing technologies, such as poor safety, low reliability, and poor aerodynamic performance, and provides efficient, reliable, and safe equipment support for marine environmental protection.

[0029] The alarm structure includes a sealed cavity 301 inside the upper cabin 2. A controller 302 is fixed inside the sealed cavity 301. An accelerometer 303 is fixed inside the sealed cavity 301. An audible and visual alarm 304 and a buzzer 305 are fixed on one side of the upper cabin 2. The accelerometer 303, the audible and visual alarm 304 and the buzzer 305 are all existing technologies.

The second floating plate 402 is polyurethane foam.

[0031] The inside of the receiving and unfolding trough 217 is fixed with a magnetic plate 5, which is magnetically connected to two legs 208, which are made of iron.

[0032] The tripod 208 has a hollow structure, and several connection holes 6 are provided on one side of the tripod 208. The connection holes 6 are evenly distributed along the length of the tripod 208.

[0033] The upper cabin 2 has a fixed cavity 7 inside, and a third float 701 is fixed inside the fixed cavity 7. The third float 701 is made of polyurethane foam.

[0034] A reflective warning tape 8 is fixed to one side of the tripod 208.

[0035] The following is a detailed explanation of the specific working principle and usage of this invention: In normal patrol and monitoring mode, the UAV body 1 relies on its onboard high-definition camera and multispectral imager and other sensors to continuously patrol the target sea area. The real-time collected video and remote sensing data are sent to the remote monitoring center through a wireless transmission system. The monitoring personnel or artificial intelligence algorithms perform synchronous analysis and judgment. Once illegal fishing, illegal sewage discharge and other illegal activities are identified, the remote center can issue instructions or the airborne controller 302 can autonomously trigger the sound and light alarm 304 and buzzer 305 to emit strong sound, light and light warning signals, and implement on-site intervention and deterrence against illegal activities.

[0036] When the drone experiences an abnormal situation, the built-in accelerometer 303 monitors flight attitude data in real time. If it detects signals consistent with a crash, such as continuous weightlessness or violent tumbling, it immediately sends a signal to the controller 302. Upon receiving the crash signal, the controller 302 immediately initiates the anti-sinking protection process. First, it controls the electric actuator 207 to retract, which in turn drives the two side unfolding plates 202 to rapidly unfold outward along the T-slot 401 via the linkage 205 mechanism. Simultaneously, once fully unfolded, the unfolding plates 202 drive the bottom rack 214 to move. The rack 214 contacts the gear 212 and engages with it, overcoming the torsion spring 212. 11. Force is applied and the U-shaped tripod 208 is released, causing the tripod 208 to unfold. If the bottom surface of the drone body 1 touches the water surface when it falls into the water, seawater is poured into the inside of the tripod 208 through the connecting hole 6 to increase the weight of the tripod 208 and provide a certain anchoring effect for the drone body 1 floating on the sea surface. If the top surface of the drone body 1 touches the water surface when it falls into the water, the unfolding of the tripod 208 makes the reflective warning strip 8 more conspicuous. During cruise, the torsion spring 211 and the magnetic plate 5 work together to retract and fix the tripod 208 in the retraction groove 217 and are attracted and fixed by the magnetic plate 5, thereby eliminating the resistance caused by the protruding parts.

[0037] The deployment plate 202 and the second float plate 402 at its bottom, together with the first float plate 216 on the bottom of the lower cabin 3, form a stable floating base, generating sufficient buoyancy to prevent the UAV from sinking. At the same time, the controller 302 simultaneously activates the audible and visual alarm 304 and the buzzer 305, and transmits the final coordinate information of the UAV back to the central control station in real time through the GPS positioning function. The third float plate 701 set in the fixed cavity 7 inside the upper cabin 2 further provides auxiliary buoyancy protection. The reflective warning strips 8 set on the side of the tripod 208 can provide visual indication at night or in low visibility. The hollow structure and the connection holes 6 on it help to reduce weight and avoid the formation of a closed airbag. The entire workflow realizes an intelligent closed loop from monitoring and early warning to autonomous protection, which significantly improves the efficiency of marine law enforcement operations and the survivability of the equipment.

[0038] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.
