Description

Technical Field

[0001] This invention relates to the field of drone transportation technology, and more particularly to a drone for the safe transport of liquid goods. Background Technology

[0002] When using drones to deliver drinking water to workers operating at heights or in complex environments, existing methods involve either installing a storage box at the bottom filled with bottled water or suspending the bottled water below the drone using a rope. Once the drone reaches the worker's location, the worker retrieves the bottled water. However, the rope suspension method causes the bottled water to sway, affecting the drone's flight stability and making it difficult to deliver the water securely to the worker, requiring the worker to time their grabbing. The storage box method requires the drone to come to a complete stop before opening it to retrieve the water, which is difficult to find a suitable landing point in complex environments, increasing the risk of landing on uneven ground and tipping over. Existing methods for transporting bottled water using drones are ill-suited to changing environments. Therefore, designing a drone that can adapt to various environments and improve water retrieval stability for the safe delivery of liquids has become an urgent technical challenge. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a drone for the safe transport of liquid items.

[0004] The present invention relates to a drone for safely transporting liquid items, comprising a drone body, a receiving compartment installed at the bottom of the drone body, an opening at the bottom of the receiving compartment, the opening extending to the front of the receiving compartment to form a pick-up / placement opening, the opening being covered by a cover plate, a rotating shaft for the receiving compartment being mounted on the rear of the cover plate, and a slide rail being mounted on the top surface of the cover plate, the receiving compartment also being equipped with a motor connected to the rotating shaft for linkage, the length direction of the slide rail being perpendicular to the pick-up / placement opening, a sliding seat being slidably connected to the slide rail, a clamping plate for clamping the mouth of a bottle of water from both sides on the sliding seat, and a detachable limiting crossbar being mounted on the pick-up / placement opening.

[0005] With the above structure, when the drone lands, the limiting bar is removed from the pick-up / placement port. A hand is inserted into the receiving compartment to push the sliding seat, causing it to move along the slide rail to the pick-up / placement port. Bottled water is placed on the sliding seat, and the bottle neck is clamped from both sides by the clamping plates, with the bottle neck facing inwards and the bottle bottom facing outwards. The sliding seat and limiting bar are then reset, and the bottled water is carried into the receiving compartment by the sliding seat. The drone is then controlled to fly near the worker and hover, aligning the pick-up port with the worker's location. During this process, the limiting bar prevents the bottled water from sliding out of the pick-up port. The motor is started remotely, and the motor works in conjunction with the flipping shaft to flip the cover downwards, opening the opening. Simultaneously, the slide rail on the cover tilts downwards, and the sliding seat is moved by the bottled water. Driven by gravity, the bottle slides to the bottom of the slide rail. The clamps on both sides hold the bottle opening in place, preventing the bottled water from shaking during the process. The bottom of the bottled water extends diagonally downwards to the front of the drone body, maintaining the distance between the drone body and the worker to prevent the drone's rotor from hitting the worker. This also shortens the distance between the bottled water and the worker, making it easier for the worker to pick up the bottled water. When the worker picks it up, the bottle opening separates from the clamps on both sides. Then, the motor drives the cover plate to reset, and the drone body returns to the starting position. This achieves the goal of transporting bottled water without landing the drone body. After opening the cover plate, the weight of the bottled water drives the sliding seat, causing the bottled water to slide downwards and forwards from the drone body. This makes it easy for the worker to steadily pick up the bottled water and adapts to transporting bottled water at high altitudes and in complex environments.

[0006] As a further improvement of this utility model, the card plate includes a fixed plate and a movable plate. The bottom of the movable plate is provided with a translation seat that fits against the sliding seat. The translation seat is threadedly connected to a drive screw. The sliding seat is provided with a screw seat that is axially connected to one end of the drive screw. The end of the drive screw is provided with a knob. The axial direction of the drive screw matches the arrangement direction of the fixed plate and the movable plate.

[0007] With the above structure, the drive screw is rotated by turning the knob. The drive screw is threadedly connected to the translation seat, which causes the translation seat attached to the sliding seat to move. The translation seat moves along the length of the drive screw, causing the movable plate to move closer to or away from the fixed plate. This can adjust the distance between the two to match the width of the bottle mouth, which helps to clamp bottled water of different sizes from both sides.

[0008] As a further improvement of this utility model, the surface of the knob is provided with anti-slip texture.

[0009] With the above structure, the surface of the knob is provided with anti-slip texture, which increases the friction when contacting the knob, making it easier to apply force to turn the knob and preventing slippage.

[0010] As a further improvement of this utility model, the two sides of the pick-up and put-out port are provided with snap-fit ​​grooves, and the opening of the snap-fit ​​groove is provided with a protruding elastic snap-fit ​​block. The size of the snap-fit ​​groove and the elastic snap-fit ​​block are matched with the size of the limiting crossbar. The two ends of the limiting crossbar are provided with positioning blocks, and the spacing of the positioning blocks is matched with the spacing of the snap-fit ​​groove.

[0011] With the above structure, the spacing of the positioning blocks matches the spacing of the locking slots. When the limiting crossbar is installed in the retrieval port, the positioning blocks abut against the side wall of the receiving compartment, preventing the limiting crossbar from sliding to the left or right and separating from the locking slot. By pushing the positioning blocks, the limiting crossbar is pressed against the elastic locking blocks. The elastic locking blocks contract, allowing the limiting crossbar to enter and exit the locking slot. At the same time, the elastic force of the elastic locking blocks can be used to press the limiting crossbar into the locking slot, preventing the limiting crossbar from falling out of the locking slot when the force on the limiting crossbar is small.

[0012] As a further improvement of this utility model, the damping slide rail tilts upward at the end near the loading / unloading port when the cover plate closes the opening.

[0013] With the above structure, when the cover plate closes the opening and closing, the end near the pick-up and drop-off port tilts upwards via the damping slide rail. In this case, the sliding seat will slide into the depth of the container due to its own weight and the weight of the bottled water, away from the pick-up port, thus avoiding the shaking of the drone body during flight, which would cause the bottled water and the sliding seat to collide with the limit bar at the pick-up port.

Detailed Implementation

[0019] like Figures 1-4The image shows a drone for safely transporting liquid items, comprising a drone body 1, a receiving compartment 2 installed at the bottom of the drone body 1, an opening 3 at the bottom of the receiving compartment 2, the opening 3 extending to the front of the receiving compartment 2 to form a pick-up / placement opening 4, the opening 3 being covered by a cover plate 5, the rear of the cover plate 5 being provided with a rotating shaft 6 for connecting the receiving compartment 2, and a slide rail 7 on the top surface, the receiving compartment 2 also being provided with a motor 8 connected to the rotating shaft 6 for linkage, the length direction of the slide rail 7 being perpendicular to the pick-up / placement opening 4, a sliding seat 9 slidably connected to the slide rail 7, the sliding seat 9 being provided with a clamping plate for clamping the mouth of a bottle of water from both sides, and the pick-up / placement opening 4 being provided with a detachable limiting crossbar 10.

[0020] When the drone body 1 lands, remove the limiting crossbar 10 from the pick-up / placement port 4, reach into the receiving compartment 2 and push the sliding seat 9 to move it along the slide rail 7 to the pick-up / placement port 4. Place the bottled water on the sliding seat 9, and clamp the bottle mouth from both sides with the clamping plate, so that the bottle mouth faces the inside of the receiving compartment 2 and the bottom of the bottle faces the outside of the receiving compartment 2. Reset the sliding seat 9 and the limiting crossbar 10, and the bottled water is carried into the receiving compartment 2 by the sliding seat 9. Control the drone body 1 to fly to the vicinity of the worker and hover, aligning the pick-up port with the direction of the worker. During this process, the limiting crossbar 10 prevents the bottled water from sliding out of the pick-up port. Start the motor 8 remotely, and the motor 8 works in conjunction with the flipping shaft 6 to drive the cover plate 5 to flip downward and open the opening 3. At the same time, the slide rail 7 on the cover plate 5 tilts downward, and the sliding seat 9 is... Driven by gravity, the bottled water slides to the bottom of the slide rail 7. The clamping plates from both sides hold the bottle mouth in place to prevent the water from shaking during this process. The bottom of the bottled water extends diagonally downwards to the front of the drone body 1, maintaining the distance between the drone body 1 and the worker to prevent the drone body 1's rotor from hitting the worker. This also shortens the distance between the bottled water and the worker, making it easier for the worker to pick up the bottled water. When the worker picks it up, the bottle mouth separates from the clamping plates on both sides. Then, the motor 8 drives the cover plate 5 to reset, and the drone body 1 returns to the starting position. This achieves the goal of transporting bottled water without landing the drone body 1. After opening the cover plate 5, the weight of the bottled water drives the sliding seat 9, causing the bottled water to slide downwards and forwards from the drone body 1. This makes it easy for the worker to steadily pick up the bottled water and adapts to transporting bottled water in high-altitude and complex environments.

[0021] The card plate includes a fixed plate 11 and a movable plate 12. The bottom of the movable plate 12 is provided with a translation seat 13 that fits against the sliding seat 9. The translation seat 13 is threadedly connected to a drive screw 14. The sliding seat 9 is provided with a screw seat 15 that is axially connected to one end of the drive screw 14. The end of the drive screw 14 is provided with a knob 16. The axial direction of the drive screw 14 matches the arrangement direction of the fixed plate 11 and the movable plate 12.

[0022] Rotating the knob 16 causes the drive screw 14 to rotate. The drive screw 14 is threadedly connected to the translation seat 13, which drives the translation seat 13, which is attached to the sliding seat 9, to move. The translation seat 13 moves along the length of the drive screw 14, causing the movable plate 12 to move closer to or further away from the fixed plate 11. This allows the distance between the two plates to be adjusted to match the width of the bottle opening, which helps to clamp bottled water of different sizes from both sides.

[0023] The surface of the knob 16 is provided with anti-slip texture 17.

[0024] The surface of the knob 16 is provided with anti-slip texture 17, which increases the friction when contacting the knob 16, making it easier to apply force to turn the knob 16 and preventing slippage.

[0025] The two sides of the take-up and put-out port 4 are provided with snap-fit ​​grooves 18. The slots of the snap-fit ​​grooves 18 are provided with protruding elastic snap-fit ​​blocks 19. The size of the snap-fit ​​grooves 18 and the elastic snap-fit ​​blocks 19 are matched with the size of the limiting crossbar 10. The two ends of the limiting crossbar 10 are provided with positioning blocks 20. The spacing of the positioning blocks 20 is matched with the spacing of the snap-fit ​​grooves 18.

[0026] By matching the spacing of the positioning blocks 20 with the spacing of the locking slots 18, when the limiting crossbar 10 is installed in the retrieval port, the positioning blocks 20 abut against the side wall of the receiving compartment 2, preventing the limiting crossbar 10 from sliding to the left or right and separating from the locking slots 18; by pushing the positioning blocks 20, the limiting crossbar 10 is pressed against the elastic locking block 19, and the elastic locking block 19 contracts, allowing the limiting crossbar 10 to enter and exit the locking slots 18. At the same time, the elastic force of the elastic locking block 19 can be used to press the limiting crossbar 10 into the locking slots 18, preventing the limiting crossbar 10 from falling out of the locking slots 18 when the force on the limiting crossbar 10 is small.

[0027] When the cover plate 5 closes the opening and closing port 3, the end of the damping slide rail 7 near the loading and unloading port 4 tilts upward.

[0028] With the cover plate 5 closing the opening 3, the end of the slide rail 7 near the take-out port 4 tilts upwards. In this case, the slide seat 9 will slide into the depth of the container 2 due to its own weight and the weight of the bottled water, away from the take-out port, so as to avoid the shaking of the drone body 1 during flight, which would cause the bottled water and the slide seat 9 to collide with the limit bar 10 towards the take-out port.
