Description

Technical Field

[0001] This invention relates to the technical field of unmanned aerial vehicles (UAVs), and more specifically to a multi-rotor UAV system with high wind resistance. Background Technology

[0002] With the rapid development of drone technology, its application in emergency rescue, environmental monitoring, and waterway inspection is becoming increasingly widespread. However, most traditional multi-rotor drones only have aerial flight capabilities and have blind spots in complex terrain or water environments: for example, they cannot stay or propel stably on the water surface, are prone to sinking and failure after falling into the water, and have poor flight stability in strong winds, which limits their all-weather, multi-scenario application capabilities.

[0003] In existing technologies, some drones achieve floating capabilities by adding floats, but these structures are bulky and generate high wind resistance, affecting flight performance. A few amphibious drones attempt to integrate surface propulsion devices, but these typically use exposed propellers or fixed structures, leading to significantly increased drag during flight, reduced wind resistance, and reliance on manual intervention for mode switching, resulting in low levels of intelligence. Furthermore, most systems lack practical functions for rescue scenarios, such as assisting in the movement of people in the water, camera stabilization, and ease of gripping.

[0004] Therefore, there is an urgent need for a new type of multi-rotor unmanned aerial vehicle (UAV) system that combines high wind resistance, air and water versatility, automatic mode switching, and high integration to solve the problems of unreasonable structure, poor environmental adaptability, and limited functionality in existing technologies. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-rotor unmanned aerial vehicle system with high wind resistance to overcome the above-mentioned defects caused by the prior art.

[0006] A highly wind-resistant multi-rotor unmanned aerial vehicle system includes: A floating board, wherein the floating board is composed of a U-shaped floating trough and a U-shaped sealing plate bonded together with adhesive; The flight assembly has two pairs symmetrically distributed on the left and right sides of the floating trough. The flight assembly is retractably housed in the floating trough. The flight assembly includes a motor and a propeller. The parade assembly is centrally located inside the floating trough and is retractably housed within the floating trough. The parade assembly includes a second motor and a second propeller. The switching components are provided in pairs and symmetrically distributed on the left and right sides of the floating trough. The switching components include a motor three and a winding wheel. The winding wheel is wound with steel wire rope one and steel wire rope two respectively. The motor three drives the winding wheel to synchronously wind or release steel wire rope one and steel wire rope two, thereby driving the flight component and the parade component to move in and out of the floating trough, realizing automatic switching between flight mode and parade mode.

[0007] Preferably, the sealing plate has two symmetrical openings on its left and right sides. The floating trough is symmetrically connected to a pair of fixed frames below the two openings. The fixed frames are symmetrically provided with a pair of fixed slots. A movable frame is provided parallel above the fixed frames. The movable frame is symmetrically provided with a pair of movable slots. A telescopic frame is slidably connected between the fixed slots and the movable slots. A compression spring is provided in the fixed slots and the movable slots. A compression spring is provided in the movable slots. An installation tube is connected between the two movable frames. The motor is coaxially connected to the installation tube through the installation frame. The propeller is connected to the output end of the motor.

[0008] Preferably, the floating trough has an opening in the middle, and an installation cylinder is provided above the opening. The side wall of the installation cylinder has water inlets evenly distributed, and the rear end has a drain outlet. The second motor is coaxially installed in the installation cylinder through a fixing ring. The second propeller is connected to the output end of the second motor. A pair of fixing columns are symmetrically connected to the left and right sides of the opening. Lifting bars are slidably connected to the fixing columns on both sides. The lifting bars are fixedly connected to the installation cylinder. A compression spring is sleeved on the fixing column.

[0009] Preferably, the motor three is fixedly installed in the floating trough by a motor base, and its output end is connected to a winding wheel. One end of the wire rope one is wound around the winding wheel, and the other end passes over the fixed pulley one provided in the floating trough and is connected to the mounting frame. One end of the wire rope two is wound around the winding wheel, and the other end passes over the fixed pulley two provided in the floating trough and is connected to the lifting bar.

[0010] Preferably, a shock-absorbing plate is connected to the middle of the front side of the floating trough, and a spherical camera is installed on the middle of the front side of the shock-absorbing plate.

[0011] Preferably, a controller is fixedly installed in the middle of the inner side of the floating tank, and a pair of battery packs are symmetrically placed on both sides of the inner side. The battery packs are electrically connected to the controller, and the controller is electrically connected to motor one, motor two and motor three respectively.

[0012] Preferably, an inverted U-shaped handrail is fixedly connected to the upper side of the sealing plate.

[0013] Preferably, a U-shaped connecting strip is detachably connected to the side wall of the mounting cylinder by a hand-tightening screw, and L-shaped push strips are symmetrically connected to the left and right sides of the connecting strip. The floating groove has an L-shaped through groove corresponding to the push strip below it.

[0014] Compared with the prior art, the present invention has the following advantages: 1. High wind resistance The symmetrical dual-sided flight component structure, combined with a low center of gravity floating plate design, significantly improves flight stability; all movable parts can be retracted and hidden, resulting in a flat shape and low wind resistance during flight, effectively enhancing maneuverability and safety in strong wind environments.

[0015] 2. Dual-use (air and water), automatic mode switching. Integrating flight and parade components, the system achieves coordinated telescopic movement via a three-motor driven steel wire rope system, enabling fully automatic switching between flight and parade modes. This adapts to the dual requirements of rapid aerial arrival and stable water surface cruising, expanding application scenarios.

[0016] 3. Compact structure and high integration All power and control modules are integrated inside the floating tank, and the flight and propulsion components can be completely housed. The overall structure is compact, making it easy to transport and deploy. The switching process is uniformly coordinated by the controller, making it simple to operate and highly intelligent.

[0017] In summary, this invention not only solves the functional shortcomings of traditional multi-rotor UAVs in water operations, but also achieves a balance of high stability, high adaptability, and high practicality through innovative structural design and intelligent control strategies, possessing significant engineering application value and broad market prospects.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1 to 9 As shown, a multi-rotor unmanned aerial vehicle (UAV) system with high wind resistance includes: The floating plate 10 is composed of a U-shaped floating channel 101 and a U-shaped sealing plate 102 bonded together with adhesive. The flight component 20 has two pairs symmetrically distributed on the left and right sides of the floating trough 101. The flight component 20 is retractably housed in the floating trough 101. The flight component 20 includes a motor 208 and a propeller 209. The parade assembly 30 is centrally located inside the floating trough 101 and is retractably housed within the floating trough 101. The parade assembly 30 includes a second motor 303 and a second propeller 304. The switching components 40 are provided in pairs and symmetrically distributed on the left and right sides of the floating trough 101. The switching components 40 include a motor 3 401 and a winding wheel 403. The winding wheel 403 is respectively wound with a steel wire rope 1 404 and a steel wire rope 2 405. The motor 3 401 drives the winding wheel 403 to synchronously wind or release the steel wire rope 1 404 and the steel wire rope 2 405, thereby driving the flight component 20 and the parade component 30 to move in and out of the floating trough 101, realizing the automatic switching between flight mode and parade mode.

[0030] This system integrates flight and water surface navigation, achieving automatic switching between "aerial flight" and "water surface cruise" modes through a scalable modular design. The flight component 20 provides lift, suitable for rapid arrival in complex terrain; the navigation component 30 provides horizontal propulsion, suitable for stable water surface cruising. The floating plate 10 structure enables the UAV to take off and land on water and float, significantly improving environmental adaptability. The integrated switching component 40 avoids increased wind resistance due to exposed structures, improving wind resistance and stability, making it suitable for various scenarios such as emergency rescue and water monitoring.

[0031] In this embodiment, the sealing plate 102 has symmetrical openings 102a on its left and right sides. The floating trough 101 is symmetrically connected to a pair of fixed frames 201 below the openings 102a. The fixed frames 201 have a pair of fixed grooves 201a symmetrically arranged on them. The fixed frames 201 are parallel to each other above the fixed frames 201. The movable frames 202 have a pair of movable grooves 202a symmetrically arranged on them. A telescopic frame 203 is slidably connected between the fixed grooves 201a and the movable grooves 202a. A compression spring 204 is provided in the fixed grooves 201a and the movable grooves 202a. A compression spring 205 is provided in the movable grooves 202a. An installation tube 206 is connected between the two movable frames 202. The motor 208 is coaxially connected to the installation tube 206 through the installation bracket 207. The propeller 209 is connected to the output end of the motor 208.

[0032] When the system needs to switch to flight mode, motor 3 401 drives the winding wheel 403 to reverse, simultaneously releasing steel wire rope 404. At this time, the telescopic frame 203 unfolds upward under the combined elastic action of compression spring 1 204 and compression spring 205, driving the movable frame 202, mounting tube 206, motor 1 208 and propeller 1 209 to rise as a whole, so that propeller 1 209 is exposed above the opening 2 102a. Then, motor 1 208 is started, driving propeller 1 209 to rotate at high speed, generating lift, and realizing the drone's flight.

[0033] When the system needs to switch to parade mode, motor 3 401 drives the winding wheel 403 to rotate clockwise, winding the steel wire rope 404. The steel wire rope applies a downward pulling force to the mounting frame 207, overcoming the elastic force of the compression spring, causing the telescopic frame 203 to retract. This drives the movable frame 202, mounting tube 206, motor 1 208, and propeller 1 209 to descend as a whole until propeller 1 209 is completely housed inside the floating trough 101 below the opening 2 102a. This state effectively lowers the overall center of gravity of the floating board 10, reducing wind resistance and collision risks, and significantly improving stability and safety during water or land parades.

[0034] In this embodiment, the floating tank 101 has a through-hole 101a in the middle, and an installation cylinder 301 is provided above the through-hole 101a. The side wall of the installation cylinder 301 is evenly provided with water inlets 301a, and the rear end is provided with a drain outlet 301b. The motor 303 is coaxially installed in the installation cylinder 301 through a fixing ring 302. The propeller 304 is connected to the output end of the motor 303. A pair of fixing columns 306 are symmetrically connected to the left and right sides of the through-hole 101a. Lifting bars 307 are slidably connected to the fixing columns 306 on both sides. The lifting bars 307 are fixedly connected to the installation cylinder 301. A compression spring 308 is sleeved on the fixing column 306.

[0035] When the system needs to switch to flight mode, motor 3 401 drives the winding wheel 403 to reverse, and simultaneously releases steel wire rope 2 405. At this time, the mounting cylinder 301 rises under the elastic action of compression springs 308 on both sides until the propeller 2 304 is completely housed in the floating groove 101 above the opening 101a, so as to avoid the exposed structure from increasing wind resistance or being impacted by airflow during flight.

[0036] When the system needs to switch to parade mode, motor 3 401 drives the winding wheel 403 to rotate forward, winding the steel wire rope 2 405. The steel wire rope applies a downward pulling force to the lifting bar 307, overcoming the elastic force of the compression spring, so that the mounting cylinder 301, motor 2 303 and propeller 2 304 are completely submerged in water. Then, motor 2 303 is started, driving propeller 2 304 to rotate at high speed, generating thrust, so as to realize the drone's water parade.

[0037] In this embodiment, the third motor 401 is fixedly installed in the floating trough 101 via the motor base 402, and its output end is connected to the winding reel 403. One end of the first steel wire rope 404 is wound around the winding reel 403, and the other end passes over the fixed pulley 406 located in the floating trough 101 and is connected to the mounting bracket 207. One end of the second steel wire rope 405 is wound around the winding reel 403, and the other end passes over the fixed pulley 407 located in the floating trough 101 and is connected to the lifting bar 307. The third motor 401 drives the winding reel 403 to rotate forward and synchronously wind the first steel wire rope 404 and the second steel wire rope 405, causing the flight component 20 to retract below the second opening 102a and the parade component 30 to protrude below the first opening 101a. The motor 401 drives the winding wheel 403 to reverse and simultaneously releases the steel wire rope 404 and the steel wire rope 405, so that the flight component 20 is exposed above the opening 102a and the parade component 30 is retracted above the opening 101a.

[0038] In this embodiment, a shock-absorbing plate 104 is connected to the center of the front side of the floating trough 101, and a spherical camera 105 is installed on the center of the front side of the shock-absorbing plate 104. The spherical camera 105 is used to acquire images of the surrounding environment in real time. The shock-absorbing plate 104 is made of an elastic material (such as silicone or rubber), which can effectively absorb vibrations during flight or water travel and prevent image blurring caused by camera shake.

[0039] In this embodiment, a controller 106 is fixedly installed in the middle of the inner side of the floating trough 101, and a pair of battery packs 107 are symmetrically placed on both sides of the inner side. The battery packs 107 are electrically connected to the controller 106, and the controller 106 is electrically connected to motor 208, motor 303, and motor 401, respectively. The controller 106 serves as the core of the system control, receiving remote control signals or executing preset programs to control flight, parade, and mode switching operations.

[0040] In this embodiment, an inverted U-shaped handrail 103 is fixedly connected to the upper side of the sealing plate 102. The handrail 103 allows the rescued person to firmly grasp the floating board 10.

[0041] In this embodiment, a U-shaped connecting strip 310 is detachably connected to the side wall of the mounting cylinder 301 by a hand-tightening screw 309. L-shaped push strips 311 are symmetrically connected to the left and right sides of the connecting strip 310. An L-shaped through groove 101 is correspondingly provided below the push strip 311 in the floating groove 101.

[0042] When the system switches to parade mode, the mounting cylinder 301 descends with the lifting bar 307, and the push bar 311 is exposed below the through groove 101b, in the working position. At this time, the drone can use the push bar 311 to gently push the drowning unconscious rescue target towards the shore during the water surface navigation, avoiding direct contact and causing secondary injury, and improving the safety and effectiveness of water rescue.

[0043] When the system switches to flight mode, the mounting cylinder 301 rises, and the push bar 311 retracts along with it to the top of the through slot 101b and is completely housed inside the floating plate 10, achieving overall structural flatness and effectively reducing air resistance and collision risk during flight.

[0044] In addition, the connecting strip 310 is detachable by using a hand-tightening screw 309, which facilitates maintenance, replacement, or selection of front-end devices with different functions such as obstacle clearing rakes and samplers according to task requirements, thereby enhancing the modularity and multi-scenario adaptability of the system.

[0045] How does this highly wind-resistant multi-rotor drone system work? 1. Flight mode activated After receiving the flight command, the controller 106 controls the motor 3 401 to rotate forward, driving the winding wheel 403 to simultaneously release the steel wire rope 1 404 and the steel wire rope 2 405.

[0046] Under the elastic action of compression spring 1 204 and compression spring 205, the flight component 20 pushes the movable frame 202 upward through the telescopic frame 203, so that motor 1 208 and propeller 1 209 are exposed above the two openings 2 102a on both sides of the floating trough 101. At the same time, under the release action of the steel wire rope 2 405, the parade component 30 is lifted by the compression spring 308, so that the mounting cylinder 301 and the propeller 2 304 are completely contained inside the floating tank 101.

[0047] Once the components are in place, motor 208 drives propeller 209 to rotate at high speed, generating lift and enabling the drone to take off vertically. Spherical camera 105 captures real-time images of the front, aiding navigation and target identification.

[0048] 2. Parade Mode Switching When the drone arrives at the target water area or receives a water surface patrol command, the controller 106 controls the motor 3 401 to reverse, driving the winding wheel 403 to synchronously wind the steel wire rope 1 404 and the steel wire rope 2 405.

[0049] The flight component 20, under the traction of the steel wire rope 404, overcomes the spring force, descends as a whole, and retracts into the floating trough 101; The parade component 30 moves downward under the traction of the steel wire rope 405, the mounting cylinder 301 is immersed in water, and the propeller 304 is in the underwater working position.

[0050] Then, the motor 2 303 is started to drive the propeller 2 304 to rotate. Water flows into the mounting cylinder 301 from the inlet 301a and is ejected at high speed through the outlet 301b, generating horizontal thrust and propelling the drone to glide smoothly on the water surface.

[0051] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
