Description

Technical Field

[0001] The present invention relates to the technical field of drone nests, and in particular to a self-propelled tower-based drone nest and a method thereof. Background Art

[0002] As a key carrier of power transmission, high-voltage cables are widely distributed in various complex terrains and environments. Regular inspection and maintenance of high-voltage cables is an important measure to ensure stable power supply and prevent major power accidents. With the rapid development of drone technology, the use of drones for high-voltage cable inspection has become a highly promising alternative. Drones can quickly reach designated locations, carry various types of testing equipment, and conduct all-round, no-dead-angle inspections of high-voltage cables, greatly improving inspection efficiency and accuracy. As an important part of the drone application system, the importance of drone nests is becoming increasingly prominent as drone application scenarios continue to expand and deepen.

[0003] For example, patent CN111392054A discloses an unmanned aerial vehicle nest, comprising: a nest body, a guide rail, two hatches, a driving device, a parking platform and a lifting device; the nest body has a nest opening on the top; the guide rail is arranged at the nest opening; the two hatches are openably arranged at the nest opening, the two hatches are movably connected to the guide rail, the two hatches slide relatively along the guide rail to open or close the nest opening, and the bottom of the hatches and the edge of the nest opening form an air guide port; the parking platform is arranged in the nest; the lifting device is arranged in the nest and drives the parking platform to rise to the nest opening.

[0004] However, the above technology has the following problems: first, the endurance of drones is limited. In long-distance high-voltage cable inspection tasks, frequent returns to the ground to charge or replace batteries will seriously affect the progress of the operation; Second, the interaction between drones and drone nests relies on data transmission, but due to the limitations of data transmission technology, the transmission range is limited, which means that drones can only fly within a specified range centered on the drone nest. Once the range is exceeded, data transmission will be interrupted or unstable; at the same time, the above-mentioned drone nest lacks adaptive capabilities and cannot flexibly adjust its own position according to changes in the actual flight range of the drone, which limits the drone's activity space and operational flexibility.

[0005] Based on this, the present invention designs a self-propelled tower-based UAV machine nest and method thereof to solve the above-mentioned problems. Summary of the invention

[0016] In order to better achieve the purpose of the present invention, the present invention also provides a method for using a self-propelled tower-based drone nest, comprising the following steps: Step 1: Transport the drone nest body to the high-voltage cable operation area. According to the spacing of the high-voltage cables, the driving device drives the rotating block to rotate, and the rotating block drives the first connecting rod and the second connecting rod to rotate, thereby driving the adjusting rod to slide on the sliding rod to adjust the positions of the four rotating plates in the adjusting assembly.

When passing the thicker connection position of the high-voltage cable, the drive wheel will expand outward. Under the action of the tension spring, the drive wheel will automatically reset after passing the thicker connection position of the high-voltage cable; Step 4: When the main body of the drone nest reaches the designated position and needs to be fixed, start the electric cylinder, which drives the hinged plate to move, and the hinged plate drives the clamping block to move. Under the action of the two moving rods, the clamping block and the fixing block tightly clamp the high-voltage cable; Step 5: When the UAV is recovered, it flies above the outer shell and then falls onto the parking platform. The driving device of the bidirectional threaded rod is started to rotate the bidirectional threaded rod. The rotation of the bidirectional threaded rod drives the two threaded blocks to move toward each other. The two threaded blocks respectively drive the two limit rods to the appropriate positions, so that the landing gear of the UAV is adjusted in the front and rear directions. Then the first synchronous belt drive module and the second synchronous belt drive module are started to drive the corresponding output sliders to move respectively. The corresponding output sliders respectively drive the first connecting block and the second connecting block to move. The first connecting block and the second connecting block respectively drive the four third sliders on the left and right sides of the parking platform to move. The four third sliders are wheeled toward the middle of the parking platform along the shape of the sliding groove. Under the action of the sliding groove, the third slider drives the L-shaped block to adjust the landing gear of the UAV in the left and right directions. At the same time, the L-shaped block locks the landing gear of the UAV so that the charging port of the UAV is facing the through groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The drone placement mechanism of the present invention uses the main space of the drone nest to stably park the drone, and the driving component, the adjustment component and the fixing component work together to achieve a compact and convenient device that can adapt to different high-voltage cable spacings and environments, and can be flexibly moved and reliably fixed on the high-voltage cable. It can flexibly adjust its own position according to changes in the actual flight range of the drone, ensuring the safety and efficiency of drone take-off and landing and related operations; 2. In the present invention, when the first cover and the second cover are opened, the cleaning wheel is in contact with the photovoltaic panel, thereby cleaning the photovoltaic panel and realizing the cleaning function of the photovoltaic panel; 3. The present invention can overcome the problem of landing point deviation caused by inaccurate positioning by means of the first positioning component and the second positioning component, and ensure that the UAV lands accurately on the parking platform; 4. When the drone needs to be charged, the present invention drives the electrical contact point into the charging port of the drone by pushing and pulling the electromagnet, thereby realizing the function of charging the drone.

[0056] The rotating plate 321 , the tension spring 322 , the connecting rod 323 , the mounting plate 324 , the motor 325 and the driving wheel 326 are each provided with four and are respectively arranged around the bottom of the drone nest body 1 .

[0057] like Figure 4 , Figure 5 and Fig.12 As shown, the fixing assembly 33 includes a cross bar 331, a fixing block 332, a clamping block 333, an electric cylinder 334, a moving rod 335 and a hinged plate 336.

[0059] like Figure 5 As shown, the inner sides of the fixing block 332 and the pressing block 333 are both provided with serrations for pressing the high-voltage cable.

[0060] The edge of the saw teeth is arc-shaped to prevent sharp corners from directly piercing the insulation layer of the cable. The arc-shaped saw teeth can better fit the round surface of the cable, disperse the pressure, and reduce local stress concentration.

[0061] Principle: The driving device drives the rotating block 311 to rotate. The rotation of the rotating block 311 drives the first connecting rod 312 and the second connecting rod 313 at both ends to rotate. The rotation of the first connecting rod 312 and the second connecting rod 313 drives the two adjusting rods 315 to move together. The two adjusting rods 315 drive the position adjustment of the rotating plates 321 on both sides, so that it can flexibly adapt to high-voltage cables with different spacings, thereby improving the applicability of the equipment under different working conditions.

[0062] When the outer shell 11 needs to adjust its position according to the range of the drone, the four motors 325 are all started, and the motors 325 drive the driving wheels 326 to rotate, thereby moving the outer shell 11; When the outer shell 11 reaches the connection position of the high-voltage cable, the connection part of the high-voltage cable will be thicker than the high-voltage cable. Therefore, the left and right driving wheels 326 will expand outward when passing the connection position of the high-voltage cable. After the driving wheel 326 expands outward after passing the thicker connection position of the high-voltage cable, it can automatically reset under the action of the tension spring 322, ensuring the continuity and stability of the equipment in a complex line environment, reducing manual intervention, and reducing the difficulty of operation.

[0063] When the outer shell 11 needs to be fixed, the electric cylinder 334 is started, and the electric cylinder 334 drives the clamping block 333 to move, and the clamping block 333 drives the moving rod 335 and the hinged plate 336 to move, so that the clamping block 333 moves closer to the position of the high-voltage cable until the clamping block 333 and the fixing block 332 tightly clamp the high-voltage cable, thereby fixing the outer shell 11 and ensuring that the equipment will not be displaced by external force during operation, thereby providing guarantee for the safe and stable operation of the equipment.

[0064] Embodiment 3: In some embodiments, Figure 1-Figure 8 As shown, as a preferred embodiment of the present invention, a method for using a self-propelled tower-based drone nest comprises the following steps: Step 1: transport the drone nest body 1 to the high-voltage cable operation area. According to the spacing of the high-voltage cables, the driving device drives the rotating block 311 to rotate, and the rotating block 311 drives the first connecting rod 312 and the second connecting rod 313 to rotate, thereby driving the adjusting rod 315 to slide on the sliding rod 314 to adjust the positions of the four rotating plates 321 in the adjusting assembly 32; Step 2: When the drone is ready to take off, the first positioning assembly 21 and the second positioning assembly 22 are unlocked from locking the drone, and the first cover 14 and the second cover 15 are opened. During the opening process of the first cover 14 and the second cover 15, the cleaning assembly 17 automatically works, and the second cover 15 drives the second mounting block 176 to move, and drives the first mounting block 171 to slide in the slide groove of the first cover 14 through the telescopic rod 177, and the cleaning wheel 175 contacts the photovoltaic panel 16 and cleans its surface; Step 3: When the drone is working outside, the drone nest body 1 needs to move according to the position of the drone, so the motor 325 is turned on, and the motor 325 drives the driving wheel 326 to rotate, so that the drone nest body 1 moves along the high-voltage cable to the working area. When passing through the thicker connection position of the high-voltage cable, the driving wheel 326 will expand outward. Under the action of the tension spring 322, the driving wheel 326 will automatically reset after passing through the thicker connection position of the high-voltage cable; Step 4: When the drone nest body 1 reaches the designated position and needs to be fixed, the electric cylinder 334 is started, the electric cylinder 334 drives the hinge plate 336 to move, and the hinge plate 336 drives the clamping block 333 to move. Under the action of the two moving rods 335, the clamping block 333 and the fixing block 332 tightly clamp the high-voltage cable; Step 5: When the UAV is recovered, it flies above the outer shell 11 and then lands on the parking platform 12. The driving device of the bidirectional threaded rod 216 is started, so that the bidirectional threaded rod 216 rotates. The rotation of the bidirectional threaded rod 216 drives the two threaded blocks 215 to move toward each other. The two threaded blocks 215 respectively drive the two limit rods 217 to the appropriate position, so that the landing gear of the UAV is adjusted in the front and rear directions. Then the first synchronous belt driving module 231 and the second synchronous belt driving module 232 are started, respectively driving the corresponding output sliders to move, and the corresponding output sliders are respectively driven to move. The first connecting block 233 and the second connecting block 234 are driven to move respectively. The first connecting block 233 and the second connecting block 234 respectively drive the four third sliders 223 on the left and right sides of the parking platform 12 to move. The four third sliders 223 are wheeled toward the middle of the parking platform 12 along the shape of the sliding groove 221. Under the action of the sliding groove 221, the third slider 223 drives the L-shaped block 222 to adjust the landing gear of the UAV in the left and right directions. At the same time, the L-shaped block 222 locks the landing gear of the UAV so that the charging port of the UAV is opposite to the through groove 133.

[0065] Step 6: When the drone needs to be charged, the push-pull electromagnet 132 is started, and the push-pull electromagnet 132 drives the electrical contact 131 to enter the charging port of the drone, thereby charging the drone.
