Description

Technical Field

[0001] The present invention relates to the technical field of buoys, and in particular to a buoy structure capable of safely parking a drone. Background Art

[0002] The buoys observe surface meteorological data (wind direction, wind speed, temperature, air pressure, humidity, etc.) and the upper ocean temperature-salinity profile and current profile. Upper-layer underwater observation data is transmitted via coupling to the buoy's internal data acquisition processor, and then transmitted back to shore stations in real time via a Beidou communication terminal. These buoys typically consist of a buoy, a support platform, sensors, and telemetry equipment. Marine survey drones are unmanned aerial vehicles used for ocean mapping and monitoring. Equipped with multispectral, hyperspectral, and thermal infrared cameras, they acquire marine ecological data such as seawater temperature, salinity, and water quality, as well as information on the distribution of marine species and seaweed cover, providing a basis for marine environmental monitoring.

[0003] When drones perform long-term missions at sea, they need to ensure safe parking if they encounter bad weather. Traditional buoys have no dedicated parking area, and drones need to land on the deck or simple brackets. They are greatly affected by waves and wind, and are prone to slippage, capsizing, or component collisions. In addition, salt spray and biological attachments are easily generated on the surface of drones during long-term flight. Long-term exposure will lead to corrosion, performance degradation, energy shortages, etc., which cannot be dealt with in a timely manner. Therefore, a buoy structure that can safely dock drones is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the existing technology that traditional buoys have no dedicated parking area, and drones need to land on the deck or simple bracket. They are greatly affected by waves and wind, and are prone to slippage, overturning or component collisions. In addition, the surface of drones is prone to salt spray and biological attachments during long-term flight, and long-term exposure will lead to corrosion, performance degradation, and energy shortages. A buoy structure is proposed that can safely dock drones.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0032] Example 1

[0033] like Figure 1 - Figure 9As shown, the present invention proposes a buoy structure for safely parking a drone, comprising a buoy 1, a parking box 2 is installed on the upper part of the buoy 1, a box door 4 is rotatably connected to the upper part of the parking box 2, and a parking assembly is provided on the parking box 2, the parking assembly comprises a first control unit, a second control unit, a movable plate 5 slidingly arranged on the inner side of the parking box 2, a U-shaped plate 8 is installed on the upper part of the movable plate 5, a fixed plate 9 symmetrically slidably arranged on the outer side of the U-shaped plate 8, and an electromagnet 6 installed on the inner side of the movable plate 5. After the drone stops on the movable plate 5 and is on the inner side of the U-shaped plate 8, the electromagnet 6 is energized to adsorb the drone, the second control unit controls the two fixed plates 9 to move towards each other and clamp the drone, the first control unit drives the movable plate 5 and the drone to move down to the inner side of the parking box 2, the box door 4 is closed, and the drone provides a stable parking platform, adsorbs the drone on the movable plate 5, and at the same time clamps the drone through the fixed plate 9 to prevent the drone from moving or sliding during the parking process, thereby ensuring parking safety;

[0034] A drone preparation component is jointly arranged between the box door 4 and the parking box 2. The drone preparation component includes a water supply unit, a third control unit, a connecting block 21 movably connected to the upper part of the movable plate 5, a first gear 22 and a second gear 24 rotatably connected to the inner side of the box door 4, a nozzle 23 installed on the inner side of the first gear 22, and a wireless charging module 7 installed on the inner side of the movable plate 5. After the box door 4 is closed, the connecting block 21 is inserted into the inner side of the second gear 24, and the wireless charging module 7 charges the drone at the same time. After charging is completed, the water supply unit sprays water mist through the nozzle 23, and the third control unit drives the second gear 24 and the first gear 22 to rotate through the connecting block 21. The rotation of the first gear 22 drives the nozzle 23 to rotate and spray water mist to the drone. After the box body 2 is closed, the active cleaning process is started to remove salt spray and biological attachments on the surface of the drone, thereby extending the life of the equipment. In addition, the drone can be charged in time after it stops, ensuring that the drone is in a usable state at any time.

[0035] The first control unit includes a second servo motor 17 installed inside the buoy 1, and a threaded rod 18 is installed at the output end of the second servo motor 17. The threaded rod 18 is threadedly connected to the movable plate 5. The force generated when the threaded rod 18 rotates can drive the movable plate 5 to move downward.

[0036] The second control unit includes a bidirectional threaded rod 13 rotatably connected to the bottom of the movable plate 5, a first bevel gear 14 is installed on the outside of the bidirectional threaded rod 13, a first servo motor 15 is installed at the bottom of the movable plate 5, and a second bevel gear 16 is installed at the output end of the first servo motor 15. The second bevel gear 16 is meshed with the first bevel gear 14. When the output end of the first servo motor 15 rotates, the bidirectional threaded rod 13 is driven to rotate through the second bevel gear 16 and the first bevel gear 14.

[0037] A sliding groove 10 is symmetrically provided on the upper part of the movable plate 5, and an L-shaped plate 11 is slidably provided on the inner side of the sliding groove 10.

[0041] In this embodiment, when it is necessary to park the drone, the door 4 can be driven to rotate by the driving device 3 until the door 4 and the parking box 2 are in a vertical state. At this time, the drone can be parked on the movable plate 5 and is at the same time in the U-shaped plate 8. When the drone is on the movable plate 5, the electromagnet 6 is energized and adsorbs the drone on the movable plate 5, and then the first servo motor 15 is started. Since the second bevel gear 16 is meshed with the first bevel gear 14, when the output end of the first servo motor 15 rotates, the bidirectional threaded rod 13 is driven to rotate through the second bevel gear 16 and the first bevel gear 14. When the bidirectional threaded rod 13 rotates, The force generated can drive the L-shaped plate 11 to move along the sliding groove 10, thereby driving the fixed plate 9 to move, so that the two fixed plates 9 clamp the drone. At this time, the second servo motor 17 can be started, and the second servo motor 17 can drive the threaded rod 18 to rotate. The force generated when the threaded rod 18 rotates can drive the movable plate 5 to move downward, and at the same time drive the drone to move to the inner side of the movable plate 5. At this time, the box door 4 is driven to rotate by the driving device 3 to close the box door 4, and then the drone is charged through the wireless charging module 7, so that the drone can be safely parked inside the parking box 2 and the drone can be replenished in time.

[0042] Example 2

[0043] like Figure 1 - Figure 9 As shown, based on the first embodiment, the third control unit includes a third servo motor 19 installed on the inside of the buoy 1, a round rod 20 is installed on the output end of the third servo motor 19, the round rod 20 is slidingly connected to the movable plate 5, and a connecting block 21 is installed at the end of the round rod 20 away from the third servo motor 19.

[0044] A connecting groove 25 is formed on the side of the second gear 24. When the door 4 is closed, the connecting block 21 is inserted into the connecting groove 25. The third servo motor 19 rotates the second gear 24 and the first gear 22 through the round rod 20 and the connecting block 21.

[0045] The water supply unit includes a water tank 26 installed inside the buoy 1, a water pump 27 installed on the upper part of the water tank 26, a connecting pipe 28 installed at the output end of the water pump 27, and a fixed connection between the end of the connecting pipe 28 away from the water pump 27 and the nozzle 23. The water pump 27 transmits the water source inside the water tank 26 to the nozzle 23 through the connecting pipe 28.

[0046] In this embodiment, when the box door 4 is closed, the connecting block 21 is inserted into the inner side of the connecting groove 25, and the third servo motor 19 is started at the same time. The third servo motor 19 can drive the round rod 20 to rotate, and at the same time drive the connecting block 21 to rotate. When the connecting block 21 rotates, it can drive the second gear 24 and the first gear 22 to rotate. When the first gear 22 rotates, it can drive the nozzle 23 to rotate. At this time, the water pump 27 is started. The water pump 27 transmits the water source inside the water tank 26 to the nozzle 23 through the connecting pipe 28. Then, the nozzle 23 converts the water source into water mist while rotating and sprays it evenly on the drone in the parking box 2. There is a small gap between the box body 2 and the buoy 1 to facilitate the outflow of water mist.
