Description

Technical Field

[0001] This utility model relates to the field of rotorcraft, and in particular to an amphibious rotorcraft. Background Technology

[0002] Rotorcraft generate lift and power through rotor rotation, enabling them to perform maneuvers such as flight, hovering, and turning. Common types include quadcopters, hexacopter drones, and helicopters. With their core advantages of flexible takeoff and landing and precise hovering, these aircraft are gradually becoming key tools in scenarios requiring operations in both water and air environments, such as fishing, water rescue, and water monitoring.

[0003] However, when applied directly to fishing operations, existing fishing reels rely heavily on manual control for reeling and casting, which lacks coordination with the aircraft's attitude. This can easily lead to tangled fishing lines or hooks entering the water incorrectly, affecting fishing accuracy. Furthermore, when a large fish is hooked, relying solely on the aircraft's lift to pull it can easily cause the equipment to malfunction or the fishing line to break due to the load exceeding the threshold, resulting in fishing failure.

[0004] Furthermore, most cameras used for observing fish activity are installed at fixed angles, and their working mechanism is not linked to the aircraft's attitude adjustment and the fishing line reeling and releasing actions. When the fish move underwater, the camera cannot dynamically follow and capture them, making it difficult for anglers to keep track of the fish's approach and biting behavior in real time, thus limiting fishing efficiency. In addition, existing rotorcraft do not have a dedicated power protection structure designed for the water surface environment, and the propeller is easily entangled by debris in the water or damaged by fish collisions, affecting the stability of the equipment. To solve the above problems, we propose an amphibious rotorcraft. Utility Model Content

[0005] The main objective of this invention is to provide an amphibious rotorcraft that can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An amphibious rotorcraft includes a main body. Connecting rods are fixedly connected to the four outer corners of the main body, and rotor bodies are mounted on the other ends of the four connecting rods. Support frames are fixedly installed on both sides of the main body, and buoyancy blocks are fixedly connected to the lower ends of two of the support frames. A first mounting block is fixedly installed at the front end of the main body, and an S-shaped connecting frame is provided at the upper end of the first mounting block. A camera body is mounted on the inner side of the S-shaped connecting frame. A second mounting block is fixedly installed at the rear end of the main body, and a fishing reel body is provided at the upper end of the second mounting block. A thruster assembly is also provided at the rear end of the main body, located below the fishing reel body.

[0008] Preferably, a double-sided snap-fit ​​block is provided on the outer side of the second mounting block, a connecting bracket is fixedly connected to the upper end of the double-sided snap-fit ​​block, a fishing reel body is fixedly connected to the rear end of the connecting bracket, a second drive motor is fixedly installed on the upper end of the double-sided snap-fit ​​block on the outer side of the connecting bracket, and the output end of the second drive motor is fixedly connected to the power input end of the fishing reel body.

[0009] Preferably, the upper end of the first mounting block is provided with a single-sided snap-fit ​​block, and the upper end of the single-sided snap-fit ​​block is rotatably connected to a rotating toothed plate, which is fixedly connected to the lower end of the S-shaped connecting frame.

[0010] Preferably, a first drive motor is fixedly installed at the lower end of the single-sided snap-fit ​​block, and a transmission gear is fixedly connected to the output end of the first drive motor. The transmission gear is rotatably connected to the upper end of the single-sided snap-fit ​​block, and the transmission gear meshes with the rotating toothed plate.

[0011] Preferably, the propulsion assembly includes two propellers, both of which are rotatably connected to the rear end of the aircraft body, and a guide plate is disposed between the two propellers, the guide plate being rotatably connected to the aircraft body.

[0012] Preferably, the rear end of the aircraft body is provided with a mounting slot, and a third drive motor is installed inside the mounting slot. The output end of the third drive motor is fixedly connected to the guide plate.

[0013] Preferably, a protective net is fixedly connected to the rear end of the aircraft body, and the protective net is fitted over the outside of the two propellers.

[0014] Preferably, a hook is installed at the lower end of the double-sided snap-fit ​​block, and the hook is located behind the protective net.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This amphibious rotorcraft connects to the main body of the fishing reel via a second drive motor, enabling automated control of fishing line release and retrieval. This effectively avoids tangling of the fishing line or deviation of the hook entering the water caused by manual control, improving fishing accuracy. At the same time, fish feed can be attached to the hook at the lower end of the double-sided clip block, allowing for targeted baiting in the target water area, attracting fish to gather, and creating more favorable conditions for fishing operations.

[0017] 2. This amphibious rotorcraft utilizes a first drive motor to engage a transmission gear with a rotating gear plate, driving the S-shaped connecting frame and camera body to rotate at multiple angles. This allows the camera to dynamically follow the movement of underwater fish, capturing their approach and bite in real time. This solves the problem of fixed-angle cameras being unable to operate in conjunction with each other, significantly improving fishing efficiency. Furthermore, when a large fish is hooked, the second drive motor maintains the tension of the fishing line. Combined with the propeller power of the thruster assembly and the direction adjustment of the guide plate, the large fish can be dragged to the shore. This avoids equipment loss of control or fishing line breakage caused by relying solely on the lift of the aircraft, ensuring the smooth completion of fishing operations.

[0018] 3. This amphibious rotorcraft, by setting a protective net at the rear of the aircraft body and covering the outside of the propeller, can effectively prevent underwater debris from getting entangled in the propeller, and at the same time prevent fish or hooked large fish from hitting the propeller and causing damage, providing reliable protection for the propulsion components and improving the stability of the equipment when operating on the water surface.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-5 As shown, an amphibious rotorcraft includes a main body 1. Connecting rods 2 are fixedly connected to the four corners of the outer side of the main body 1. A rotor body 3 is installed at the other end of each of the four connecting rods 2. Support frames 4 are fixedly installed on both sides of the main body 1. Buoyancy blocks 5 are fixedly connected to the lower ends of the two support frames 4. A first mounting block 7 is fixedly installed at the front end of the main body 1. An S-shaped connecting frame 10 is provided at the upper end of the first mounting block 7. A camera body 11 is installed on the inner side of the S-shaped connecting frame 10. A second mounting block 14 is fixedly installed at the rear end of the main body 1. A fishing reel body 17 is provided at the upper end of the second mounting block 14. A thruster assembly is also provided at the rear end of the main body 1, and the thruster assembly is located below the fishing reel body 17.

[0027] In this embodiment, a double-sided snap-fit ​​block 15 is provided on the outer side of the second mounting block 14. A connecting bracket 16 is fixedly connected to the upper end of the double-sided snap-fit ​​block 15. A fishing reel body 17 is fixedly connected to the rear end of the connecting bracket 16. A second drive motor 18 is fixedly installed on the upper end of the double-sided snap-fit ​​block 15 on the outer side of the connecting bracket 16. The output end of the second drive motor 18 is fixedly connected to the power input end of the fishing reel body 17.

[0028] Specifically, by activating the high-speed rotation of the rotor body 3 at the end of the connecting rod 2 at the four corners on the outside of the main body 1, lift is generated, propelling the main body 1 into the air and accurately flying to the target fishing area. Using two buoyancy blocks 5, the main body 1 floats on the water. Then, the second drive motor 18 at the rear of the main body 1 is activated. The output of the second drive motor 18 drives the fishing reel body 17 to rotate, slowly releasing the fishing line and smoothly placing the hook attached to the line into the water. More specifically, the power source for the activation and rotation of the rotor body 3 and the activation of the second drive motor 18 is the internal power source of the main body 1. The device in this paper has not undergone structural modifications, and those skilled in the art are familiar with its working principle and can apply it proficiently based on their professional knowledge. Therefore, this paper will not elaborate on it further. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not describe the electronic control program in detail, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0029] In this embodiment, a single-sided snap-fit ​​block 8 is snapped onto the upper end of the first mounting block 7. A rotating toothed plate 9 is rotatably connected to the upper end of the single-sided snap-fit ​​block 8. The rotating toothed plate 9 is fixedly connected to the lower end of the S-shaped connecting frame 10. A first drive motor 12 is fixedly installed at the lower end of the single-sided snap-fit ​​block 8. A transmission gear 13 is fixedly connected to the output end of the first drive motor 12. The transmission gear 13 is rotatably connected to the upper end of the single-sided snap-fit ​​block 8, and the transmission gear 13 meshes with the rotating toothed plate 9.

[0030] Specifically, by starting the first drive motor 12, the output of the first drive motor 12 will drive the transmission gear 13 to rotate. Through the meshing of the transmission gear 13 with the rotating toothed plate 9, the rotating toothed plate 9 can drive the S-shaped connecting frame 10 and the inner camera body 11 to rotate at multiple angles. The camera body 11 can observe in real time whether the fish in the water are hooked. When a small fish is observed to be hooked, the second drive motor 18 is started again to drive the fishing reel body 17 to retrieve the fishing line. At the same time, the rotor body 3 is started to generate lift, which drives the aircraft body 1 and the hooked small fish to take off directly in the air and return to the shore.

[0031] In this embodiment, the thruster assembly includes two propellers 20, both of which are rotatably connected to the rear end of the aircraft body 1. A guide plate 21 is provided between the two propellers 20 and is rotatably connected to the aircraft body 1. A mounting slot is provided at the rear end of the aircraft body 1, and a third drive motor 22 is installed inside the mounting slot. The output end of the third drive motor 22 is fixedly connected to the guide plate 21. A protective net 23 is fixedly connected to the rear end of the aircraft body 1 and is sleeved on the outside of the two propellers 20. A hook 19 is installed at the lower end of the double-sided snap-fit ​​block 15 and is located behind the protective net 23.

[0032] Specifically, if a large fish is observed to be hooked, to avoid excessive load on the aircraft, the second drive motor 18 first controls the fishing reel body 17 to maintain the fishing line tension, and then the rear propeller assembly of the aircraft body 1 is activated. At this time, the two propellers 20 in the propeller assembly rotate to generate power. In conjunction with the third drive motor 22 in the mounting slot at the rear of the aircraft body 1, the guide plate 21 is driven to adjust the direction of travel, dragging the hooked large fish to the shore. During the movement of the aircraft body 1 towards the shore, the protective net 23 protects the propellers 20 to prevent the large fish on the hook from colliding with the propellers 20 and causing damage to the propellers 20. The design of the hook 19 is mainly to carry fish food, which follows the aircraft body 1 into the air and flies accurately to the target fishing area to create a feeding area in that area, thereby attracting fish to gather.

[0033] More specifically, the rotation power of the propeller 20 is also based on the power battery inside the aircraft body 1. The power battery provides power to drive two drive motors that drive the propeller 20 to rotate, thereby making the propeller 20 rotate and propelling the aircraft body 1 to move. Similarly, the power source for the first drive motor 12 and the third drive motor 22 is also the power battery inside the aircraft body 1. Furthermore, the first drive motor 12 and the third drive motor 22 have not undergone structural modifications in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them proficiently. Thus, this paper will not elaborate further. In addition, all electrical equipment in this paper has been waterproofed, so there will be no problem of water ingress and equipment failure when the aircraft body 1 is moving on the water surface.

[0034] It should be noted that this utility model is an amphibious rotorcraft. The user first uses the hook 19 at the lower end of the double-sided connecting block 15 to attach fish food, then attaches bait to the hook wound around the fishing reel body 17. At this time, the rotor body 3 at the end of the connecting rod 2 at the four corners on the outer side of the aircraft body 1 rotates at high speed to generate lift, propelling the aircraft body 1 into the air and accurately flying to the target fishing area. Then, through the two buoyancy blocks 5, the aircraft body 1 floats on the water surface, and the fish food on the hook 19 falls into the water. The system baits the target area in the water to attract fish. After baiting, the second drive motor 18 at the rear of the main body 1 of the aircraft is activated. The output of the second drive motor 18 drives the fishing reel 17 to rotate, slowly releasing the fishing line and smoothly placing the hook attached to the line into the water. At the same time, the first drive motor 12 is activated, and its output drives the transmission gear 13 to rotate. Through the engagement of the transmission gear 13 with the rotating gear plate 9, the rotating gear plate 9 can drive the S-shaped connecting frame 10 and the inner camera. The main body 11 rotates at multiple angles, and the camera on the main body 11 monitors in real time whether fish are being hooked underwater. When a small fish is observed to be hooked, the second drive motor 18 is activated again to drive the fishing reel 17 to retrieve the fishing line. At the same time, the rotor body 3 is activated to generate lift, which propels the aircraft body 1 and the hooked small fish directly into the air to return to the shore. If a large fish is observed to be hooked, to avoid excessive load on the aircraft, the second drive motor 18 first controls the fishing reel 17 to maintain the fishing line tension, and then the rear thruster assembly of the aircraft body 1 is activated. At this time, the two thrusters in the thruster assembly... The propeller 20 generates power by rotating. In conjunction with the third drive motor 22 installed in the mounting slot at the rear of the main body 1, the guide plate 21 is driven to adjust the direction of travel, dragging the hooked fish to the shore. During the movement of the main body 1 towards the shore, the protective net 23 protects the propeller 20, preventing the fish on the hook from colliding with the propeller 20 and causing damage. Furthermore, the buoyancy blocks 5 at the lower end of the support frames 4 on both sides of the main body 1 can assist the main body 1 to move smoothly on the water surface, thus completing the entire fishing operation process. This method is quite practical.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
