[0003] Although drone technology has made significant progress, it still has some shortcomings and challenges. For example, most existing drones are limited by their functional design and can only perform tasks effectively in specific environments, which reduces the flexibility and versatility of operations.
[0004] Therefore, it is necessary to design a multi-functional unmanned aerial vehicle (UAV) for land, sea, and air. Utility Model Content

A sleeve is fixedly connected to the top of the UAV body. Slide bars are slidably connected to the front and rear sides inside the sleeve. A mounting bracket is fixedly connected to the bottom of each slide bar. The rotating shaft is rotatably connected to the mounting bracket.
[0008] Furthermore, it is particularly preferred that the surface navigation mechanism includes a buoy, a third motor, a float plate, and an impeller.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0024] Example: A multi-functional unmanned aerial vehicle (UAV) for sea, land, and air use, such as Figures 1-4 , Figure 6 and Figure 7 As shown, the device includes a drone body 1, a mounting frame 2, a first motor 3, and blades 4. The drone body 1 is made of high-strength, low-density carbon fiber composite material. Carbon fiber composite material has an excellent strength-to-weight ratio, which can effectively reduce the weight of the drone while ensuring the stability of the drone structure, thereby improving flight performance and endurance. The mounting frame 2 is welded to the bottom of the drone body 1. The mounting frame 2 is made of aluminum alloy, which can stably support the various components of the drone and meet the dual requirements of lightweight and strength of the drone's structural components. The mounting frame 2 is equipped with symmetrical first motors 3 on both the front and rear sides. Blades 4 are connected to the output shaft of the first motor 3. The blades 4 rotate at high speed, and the pressure difference between the upper and lower surfaces of the blades 4 generates an upward lift, which enables the drone body 1 to leave the ground and remain suspended in the air. The device also includes a land driving mechanism and a water navigation mechanism. The drone body 1 is equipped with a land driving mechanism and a water navigation mechanism.
[0025] like Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, the land-based driving mechanism includes an electric push rod 6, a connecting rod 7, a second motor 8, a rotating shaft 9, a mounting bracket 10, a drive wheel 11, a sliding rod 12, and a sleeve 13. The electric push rod 6 is installed on the left side of the UAV body 1. The connecting rod 7 is connected to the telescopic rod of the electric push rod 6. The second motor 8 is installed on the connecting rod 7. The second motor 8 is a dual-axis motor. The output shafts of the second motor 8 are all connected to rotating shafts 9. The drive wheel 11 is fixedly connected to the side of the rotating shafts 9 that are far apart from each other. The rotation of the drive wheel 11 generates friction with the ground, which drives the UAV to move on the land. The sleeve 13 is welded to the top of the UAV body 1. Both the sliding rod 12 and the sleeve 13 are made of stainless steel, which can ensure that the sliding rod slides smoothly in the sleeve and has strong corrosion resistance, making it suitable for outdoor environments. The sliding rod 12 is slidably connected to the front and rear sides inside the sleeve 13. The mounting bracket 10 is welded to the bottom of the sliding rod 12. The rotating shaft 9 is rotatably connected to the mounting bracket 10.
[0026] like Figure 6 As shown, the water surface navigation mechanism includes a float hull 16, a third motor 17, a float plate 18, and an impeller 19. The float hull 16 is welded onto the fixed frame 2. The third motor 17 is installed at the bottom inside the float hull 16. The third motor 17 is a dual-shaft motor, and the output shafts of the third motor 17 are connected to the impellers 19. Float plates 18 are welded to both the front and rear sides of the float hull 16. The float hull 16 and the float plates 18 are both made of engineering plastics, which have the characteristics of low density, high buoyancy, and resistance to water immersion and chemical corrosion. They can provide reliable buoyancy support for the UAV to navigate on the water surface. The float hull 16 and the float plates 18 provide buoyancy for the UAV body 1, enabling it to float on the water surface and ensuring the stability of the UAV body 1 on the water surface, preventing it from capsizing or sinking. The lower end of the impeller 19 extends out of the float plate 18. The impeller 19 rotates at high speed, generating a backward thrust on the water. The water will generate a forward reaction force on the impeller 19, thereby propelling the UAV body 1 forward on the water surface.
[0027] like Figure 2 and Figure 7 As shown, it also includes a filter screen 5 and a camera 20. The front and rear sides of the mounting frame 2 are welded with symmetrical filters screen 5. The filters screen 5 can prevent debris, aquatic plants and other things in the water from entering the mounting frame 2 and affecting the use of the blades 4. The right side of the UAV body 1 is equipped with a camera 20. The camera 20 can collect images and video information of the surrounding environment in real time and transmit them to the ground control station through wireless communication technology. The operator can understand the environment and mission target of the UAV body 1 based on the images transmitted back by the camera 20, so as to more accurately control the flight, driving or navigation direction of the UAV body 1 and complete various reconnaissance, monitoring and other tasks.
[0028] like Figure 1 , Figure 4 , Figure 5 and Figure 7As shown, it also includes a cover plate 14, a connecting block 15, and a spring 1501. The cover plate 14 is fixedly connected to both the front and rear sides of the mounting bracket 2, and the connecting block 15 is fixedly connected to both the left and right sides of the two mounting brackets 10. The cover plate 14 and the connecting block 15 are slidably connected, and the connecting block 15 and the cover plate 14 are connected by a spring 1501. The spring 1501 can reduce the impact of vibration on the drone body 1 and ensure the stability of the drone body 1 during travel.
[0029] When the device is needed for flight, the first motor 3 is activated. The output shaft of the first motor 3 rotates, driving the blades 4 to rotate at high speed. The pressure difference between the upper and lower surfaces of the blades 4 generates upward lift, allowing the drone body 1 to leave the ground and remain suspended in the air. The flight attitude and direction of the drone body 1 can be adjusted by adjusting the speed of the output shafts of the first motors 3 in all directions. After the flight operation is completed, the first motor 3 is turned off. When the device is needed for driving on land, the electric push rod 6 is activated. The telescopic rod of the electric push rod 6 retracts, driving the connecting rod 7 downward. The downward movement of the connecting rod 7 causes the sliding rod 12 to move within the sleeve 13. The part slides downwards, the slide bar 12 moves downwards, causing the mounting frame 10 to descend. The mounting frame 10 moves downwards, causing the drive wheel 11 to move downwards until it contacts the ground. The electric push rod 6 is turned off, and then the second motor 8 is started. The output shaft of the second motor 8 rotates, causing the drive wheel 11 to rotate. The drive wheel 11 generates friction with the ground, propelling the drone on land. When the drone travels on uneven ground, the drive wheel 11 experiences vibration, which is transmitted to the connecting rod 7 through the mounting frame 10. This causes the connecting block 15 to slide upwards on the cover plate 14, compressing the spring 1501. This reduces the impact of vibration on the drone body 1, ensuring the stability of the drone body 1 during travel. (Land work conclusion) After the second motor 8 is turned off, when the device needs to navigate on the water, the electric push rod 6 is activated. The telescopic rod of the electric push rod 6 extends and retracts, causing the connecting rod 7 to move upward, which in turn causes the sliding rod 12 to slide upward inside the sleeve 13, causing the mounting frame 10 to descend until the drive wheel 11 moves upward and resets. The electric push rod 6 is then turned off. The float hull 16 and float plate 18 provide buoyancy to the UAV body 1, enabling it to float on the water surface and ensuring the stability of the UAV body 1 on the water surface, preventing it from capsizing or sinking. The third motor 17 is then activated. The output shaft of the third motor 17 rotates, causing the impeller 19 to rotate at high speed, generating a backward thrust on the water. The water will then exert a forward thrust on the impeller 19. The reaction force propels the UAV 1 forward on the water surface. The filter 5 prevents debris and aquatic plants from entering the fixed frame 2 and affecting the use of the blades 4. After the underwater navigation operation is completed, the third motor 17 is turned off. The camera 20 can collect images and video information of the surrounding environment in real time and transmit them to the ground control station through wireless communication technology. The operator can understand the environment and mission target of the UAV 1 based on the images transmitted back by the camera 20, so as to more accurately control the flight, driving or navigation direction of the UAV 1 and complete various reconnaissance, monitoring and other tasks, thereby completing the aerial, land and water operations of the UAV 1.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
