Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicles (UAVs), specifically to a compact UAV nest suitable for tower mounting. Background Technology

[0002] In fields such as power line inspection and communication base station monitoring, towers, as high-altitude infrastructure, are characterized by their wide distribution and moderate height. If drone nests can be deployed on towers, drones can use the towers as bases to carry out routine inspections without having to take off and land frequently from the ground, which will greatly improve operational efficiency and coverage, while reducing dependence on ground sites. Therefore, there is an urgent need for such compact drone nests.

[0003] However, traditional drone nests are usually installed by bolting or welding, which is not only time-consuming and labor-intensive, but also difficult to adapt to tower structures of different diameters, resulting in poor stability. Secondly, traditional nests lack effective shock absorption and angle adjustment functions, making drones susceptible to vibration during take-off and landing, leading to equipment damage or positioning deviations. In addition, traditional nests with limited functions cannot provide services such as charging for drones, increasing manual maintenance costs and reducing operational efficiency. Therefore, we propose a compact drone nest suitable for tower installation. Summary of the Invention

[0029] Compared with the prior art, the present invention provides a compact drone nest suitable for tower installation, which has the following features:

[0030] Beneficial effects:

[0031] 1. This compact drone housing suitable for tower installation uses a clamping mechanism. The hydraulic cylinder and piston rod in the transmission assembly drive the push plate to move. Combined with the hinge structure of the connecting rod and the connecting shaft, the clamp can tightly grip the tower. The locking teeth and spring in the stabilizing component of the inner arc surface of the clamp can adapt to towers of different diameters, enhancing the stability and adaptability of the installation.

[0032] 2. This compact drone nest suitable for tower installation has a nest base mechanism that includes a shock-absorbing component and an angle tilting component. The sliding ring, spring 1, and connecting rod 4 in the shock-absorbing component can effectively absorb the vibration during drone take-off and landing. The angle tilting component drives the nest support to tilt through hydraulic cylinder 1 and piston rod 1. With the sliding connection of limit shaft and arc groove, the nest angle can be adjusted according to needs. Compared with traditional nests, which have poor shock absorption and inconvenient angle adjustment, this greatly improves the stability of drone take-off and landing and the flexibility of nest use.

[0033] 3. This compact drone nest, suitable for tower installation, features a nest enclosure mechanism where a motor drives a lead screw to rotate, causing a sliding block to move. This movement is then connected to two connecting rods, which in turn move the sliding enclosure plate, allowing the enclosure to open and close. The charging contacts and magnetic metal sheets in the drone auxiliary components enable precise charging and positioning of the drone. Rainwater can be drained from the outlet through the tilting component, solving the problem of the traditional single-function drone nest and improving its practicality. Attached Figure Description

[0055] The hinge block on piston rod 22 is hinged to the hinge seat at the bottom of the machine nest support 9;

[0056] The limiting shaft 23 and the arc groove 24 are slidably connected. The cooperation between the limiting shaft 23 and the arc groove 24 can control the tilt angle of the nest support 9, preventing excessive tilting from damaging the equipment inside the nest or causing the drone to slip off.

[0057] Furthermore, a support plate 18 is fixedly installed on one side of the upper surface of the nest support base 9, and brackets 29 are symmetrically fixedly installed on both sides of the upper surface of the nest support base 9 corresponding to the support plate 18.

[0058] Support plates are symmetrically fixed to the outer wall of bracket 29 near the support plate 18.

[0059] Furthermore, the nest enclosure mechanism includes a sliding block 16, a lead screw 17, and a motor 19. The lead screw 17 is rotatably connected between two support plates on the bracket 29.

[0066] Structural Description:

[0067] Support 1: Support 1 is the main support of the UAV nest. A connecting plate is fixed on one side wall for installing the clamping mechanism. It provides basic support for the entire nest and ensures the stability of the nest after it is installed on the tower. It is an important basic part of the nest structure.

[0068] Push plate 2: Push plate 2 is installed on the side wall of the support base 1 with the connecting plate. It is driven by the piston rod 28 of the hydraulic cylinder 27. Inclined waist-shaped holes are opened on both sides of its plane. It is slidably connected to the connecting shaft on the connecting rod 3. It realizes the transmission of the clamp 4 by moving. It is the key transmission component of the clamping mechanism.

[0069] Link 1 3: One end of link 1 3 is hinged to the connecting shaft 1 of support base 1, and the other end is hinged to the connecting shaft 2 of support base 1. The connecting shaft at this end is slidably connected to the waist-shaped hole of push plate 2. By moving push plate 2, link 1 3 is driven to rotate, thereby realizing the clamping or loosening action of clamp 4.

[0070] Clamp 4: Clamp 4 is installed on the transmission assembly. The outer arc surface has a hinge block that is hinged to the connecting rod 3. The inner arc surface is equipped with a stabilizing component. It contacts the iron tower through the locking teeth 25 and the spring 26, which can tightly hug iron towers of different diameters and enhance the stability of the machine nest installation.

[0071] Base plate 5: Base plate 5 is fixed on the upper plane of support base 1 and is the foundation of the nest base mechanism. It has support blocks at its four corners and connecting rods between the support blocks. It is used to install the sliding ring 6 and spring 7 of the shock absorption component, providing a shock absorption foundation structure for the nest.

[0072] Sliding ring 6: Sliding ring 6 is symmetrically slidably connected to the connecting rod of the base plate 5. There is a spring 7 between the two sliding rings 6 on the same side. The upper part of the spring 7 is hinged to the connecting rod 20. By sliding on the connecting rod and acting on the spring 7, the shock absorption function of the machine nest is realized.

[0073] Spring 7: Spring 7 is coaxially sleeved on the connecting rod of the base plate 5 and located between the two sliding rings 6 on the same side. When the drone is vibrated, spring 7 is compressed or extended to absorb the vibration energy. Together with the sliding ring 6 and the connecting rod 20, it effectively reduces the vibration of the drone during take-off and landing.

[0074] Support base 8: The bottom surface of support base 8 has four hinge blocks, which are hinged to the other end of connecting rod 4 20. The support plate of the tilting component, hydraulic cylinder 1 21 and other components are installed on it. It is the intermediate support structure connecting the shock absorption component and the tilting component.

[0075] Nest support 9: Nest support 9 is located above the tilting component. Its bottom surface has a rotating support plate and an arc groove 24, which is slidably connected to the limiting shaft 23. It can be tilted by hydraulic cylinder 21. Its upper surface is equipped with support plate 18, bracket 29, etc., for supporting the UAV and related mechanisms.

[0076] Water outlet 10: Water outlet 10 is equidistantly opened on the side wall of the machine nest support base 9 facing the support plate 18. When the machine nest is tilted by the angle tilting component, rainwater and other water can be discharged from the water outlet 10 to prevent water accumulation in the machine nest and protect the internal equipment.

[0077] Charging contact 11: The charging contact 11 is fixed in the middle of the landing plane of the nest support 9. When the drone lands on the nest, it connects with the drone charging interface to provide charging function for the drone and solve the drone's battery life problem.

[0078] Magnetic conductive metal sheet 12: The magnetic conductive metal sheet 12 is installed at the four corners of the landing plane of the nest support 9. It uses magnetic force to attract the drone, helping the drone to accurately locate the landing position, and at the same time enhances the stability of the nest when the drone lands.

[0079] Sliding enclosure 13: The sliding enclosure 13 slides on the bracket 29. It has a rotating shaft at the top and an oblong hole at the bottom. It is opened and closed through the transmission of connecting rod 3 15 and connecting rod 2 14. It is used to form a drone nest fence to protect the drones and equipment inside the nest.

[0080] Link 2 14: One end of link 2 14 is hinged to the rotating shaft of sliding block 16, and the other end is hinged to the rotating shaft of sliding enclosure 13. It is cross-hinged with link 3 15. When sliding block 16 moves, it drives sliding enclosure 13 to move through link 2 14. It is one of the transmission links of the nest enclosure mechanism.

[0081] Link 3 15: One end of link 3 15 is hinged to the rotating shaft of bracket 29, and the other end is slidably connected to the waist-shaped hole of sliding plate 13. It is cross-hinged with link 2 14 in the middle. By moving the sliding block 16, link 3 15 is driven to rotate, thereby realizing the lifting and lowering of sliding plate 13.

[0082] Sliding block 16: Sliding block 16 is threadedly connected to lead screw 17. A rotating shaft is fixed on one side wall of the sliding block 16 and is hinged to connecting rod 2 14. When motor 19 drives lead screw 17 to rotate, sliding block 16 moves on lead screw 17, thereby driving connecting rod 2 14 and connecting rod 3 15 to move, realizing the opening and closing control of sliding panel 13.

[0083] Lead screw 17: Lead screw 17 is rotatably connected between the two support plates of bracket 29. The output shaft of motor 19 is fixed coaxially with it. The motor 19 drives lead screw 17 to rotate, causing sliding block 16 to move on lead screw 17, thereby realizing the power transmission of the fence mechanism.

[0084] Support plate 18: The support plate 18 is fixed to one side of the upper surface of the nest support base 9 and is used to install components such as bracket 29, providing support for the nest fence mechanism and UAV auxiliary components, and enhancing the stability of the nest structure.

[0085] Motor 19: Motor 19 is installed on the bottom surface of the support plate below bracket 29. The output shaft is coaxially fixed with lead screw 17. It serves as the power source for the nest enclosure mechanism. By driving lead screw 17 to rotate, it moves sliding block 16 and controls the opening and closing of sliding enclosure 13.

[0086] Link 4 20: One end of link 4 20 is hinged to the hinge seat on the upper surface of the sliding ring 6, and the other end is hinged to the hinge block on the bottom surface of the support seat 8. Through the sliding of the sliding ring 6 and its own rotation, in conjunction with the spring 1 7, the shock absorption function of the machine nest is realized.

[0087] Hydraulic cylinder 21: Hydraulic cylinder 21 is hinged in the hinge seat on the upper plane of support seat 8, and the other end of its piston rod 22 is hinged to the bottom of the machine nest support seat 9. By extending and retracting hydraulic cylinder 21, the piston rod 22 is moved, causing the machine nest support seat 9 to tilt around the hinge point.

[0088] Piston rod 22: Piston rod 22 is connected to hydraulic cylinder 21 for transmission, and its other end is hinged to the bottom hinge seat of the machine nest support 9. Under the action of hydraulic cylinder 21, it extends and retracts, causing the machine nest support 9 to tilt, thereby realizing the angle adjustment function.

[0089] Limiting shaft 23: The limiting shaft 23 is symmetrically fixed on the opposite surface of the support plate of the support base 8 and is slidably connected to the arc groove 24 on the rotating support plate of the nest support base 9. When the nest support base 9 is tilted, the limiting shaft 23 slides in the arc groove 24 to limit the tilt range and guide it.

[0090] Arc groove 24: Arc groove 24 is formed on the rotating support plate of the machine nest support 9 and is slidably connected to the limiting shaft 23. When the hydraulic cylinder 21 drives the machine nest support 9 to tilt, the arc groove 24 slides along the limiting shaft 23 to ensure smooth tilting action and limit the angle.

[0091] Clamping teeth 25: Clamping teeth 25 are fixed at equal intervals on the inner arc surfaces of the two clamps 4. When in contact with the surface of the iron tower, clamping teeth 25 are embedded in the iron tower, which enhances the friction between the clamps 4 and the iron tower and the connection stability, and is suitable for iron towers of different diameters.

[0092] Spring 26: Spring 26 is installed in the connecting hole between the two teeth 25 on the inner arc surface of the clamp 4. When the clamp 4 clamps the iron tower, spring 26 is compressed, so that the teeth 25 fit the iron tower surface better, enhancing adaptability and stability.

[0093] Hydraulic cylinder 27: Hydraulic cylinder 27 is fixed on the side wall of the support base 1 with the connecting plate, and is connected to piston rod 28. By extending and retracting hydraulic cylinder 27, piston rod 28 is moved, thereby pushing push plate 2 to achieve the clamping or loosening of clamp 4.

[0094] Piston rod 28: Piston rod 28 is connected to hydraulic cylinder 27, and the other end is fixed to push plate 2. It extends and retracts under the action of hydraulic cylinder 27, driving push plate 2 to move. It is the key transmission component for pushing push plate 2 in the clamping mechanism.

[0095] Support bracket 29: Support bracket 29 is symmetrically fixed on both sides of the support plate 18 on the upper surface of the nest support base 9. Its outer wall has upper and lower symmetrical support plates for installing components such as screw rod 17 and motor 19. It is the support structure of the nest enclosure mechanism.

[0096] Working principle: When the machine nest needs to be installed on the iron tower, hydraulic cylinder 27 is activated, and its piston rod 28 extends to drive the push plate 2 to move. The inclined waist-shaped hole on the push plate 2 slides and engages with the connecting shaft on the connecting rod 3, causing the connecting rod 3 to rotate around the connecting shaft 1 and connecting shaft 2 on the support base 1. This, in turn, drives the clamp 4 to tighten around the iron tower. The locking teeth 25 on the inner arc surface of the clamp 4 contact the surface of the iron tower. The spring 26 between the locking teeth 25 is deformed by pressure, adapting to different diameters of the iron tower, enhancing the stability and adaptability of the clamping, and realizing the firm installation of the machine nest on the iron tower.

[0097] When the drone is preparing to land in the nest, motor 19 drives lead screw 17 to rotate, causing sliding block 16 to move along lead screw 17. Sliding block 16 pushes connecting rod 2 14 and cross-hinged connecting rod 3 15 to move through rotating shaft. Connecting rod 2 14 pulls the rotating shaft at the top of sliding enclosure 13, while connecting rod 3 15 slides along the waist-shaped hole of sliding enclosure 13, so that multiple sliding enclosures 13 unfold synchronously to form a protective fence. During the drone landing, the shock absorption component of the nest base mechanism plays a role. The impact force of the drone landing is transmitted to the nest support seat 9, and then to the sliding ring 6 through connecting rod 4 20. The sliding ring 6 slides on the connecting rod of the base plate 5, compressing spring 1 7. The elastic force of spring 1 7 absorbs the vibration energy, reduces the impact of vibration on the nest and drone, and ensures that the drone lands smoothly.

[0098] When the drone lands on the landing surface of the nest support 9, the magnetic metal plates 12 near the four corners of the landing surface use magnetic force to attract the drone, enabling the drone to be accurately positioned. At the same time, the charging contact 11 in the middle of the landing surface connects with the drone's charging interface to charge the drone. When it is necessary to drain the rainwater from the nest, the hydraulic cylinder 21 is activated, and its piston rod 22 extends or retracts, causing the nest support 9 to rotate around the hinge seat at the bottom. The arc groove 24 on the rotating support plate on the bottom surface of the nest support 9 slides on the limiting shaft 23 on the support 8, limiting the tilt angle of the nest and causing the nest to tilt. The rainwater is drained from the water outlet 10 on the side wall of the support plate 18 facing the nest support 9.
