Description

Technical Field

[0001] This invention belongs to the field of power cable technology, specifically relating to a ground mobile workstation for unmanned aerial vehicle (UAV) inspection of power transmission lines. Background Technology

[0002] Cables are a common device for transmitting electricity. Due to terrain and environmental limitations, existing cables are laid using specialized power towers for support, keeping them away from the ground. This method effectively avoids direct contact between cables and surrounding people or trees. However, because the cables are erected at high heights, subsequent inspections and patrols by operators require excessive time for vertical movement. Therefore, specialized inspection drones are now used to assist in inspection operations. The inspection robot can move along the cable's laying path, taking pictures of the cable. The captured images are then transmitted to the drone's control terminal, allowing operators to assess the cable's condition based on its outer surface.

[0003] Current drones can move stably along cable laying paths, facilitating cable inspection by operators. However, certain problems exist in practical use. Specifically, to clearly capture images of the cable's outer surface, existing drones fly at slow speeds, requiring them to move slowly along the cable laying path. This significantly limits the drone's working time; a single full charge may only allow it to inspect the current two-kilometer length of cable, thus restricting its overall battery life. Furthermore, to ensure clear images for operator observation and maintenance, the drone's built-in memory is excessively occupied. To facilitate subsequent processing, the captured videos cannot be deleted, resulting in a significant reduction in the overall inspection efficiency of the drone. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] A ground mobile workstation for UAV inspection of power transmission lines includes a mobile frame, a control system, and a placement platform. The control system is installed on one side of the mobile frame, and the placement platform is installed on the other side of the mobile frame. The placement platform stores and supports the UAV. A power supply unit is installed on the placement platform to supply power to the UAV to improve its endurance. A limiting mechanism is installed on the placement platform to lock the position of the UAV, assist the mobile frame in moving the UAV, and ensure the stability of the UAV during charging.

[0007] As a preferred embodiment of the present invention, the limiting mechanism includes an electric push rod, an extrusion block, and an extrusion side plate. A sliding groove is provided in the placement platform, and an electric push rod is installed in the sliding groove. An extrusion block is installed at the output end of the electric push rod. Extrusion side plates are symmetrically installed in the sliding groove. A limiting block that fits against the upper surface of the UAV support frame is installed at the end of the extrusion side plate. First springs are symmetrically installed at both ends of the extrusion side plate. When the extrusion side plate is extruded by the extrusion block and moves outward, the first springs enter a charging state. A limiting component is installed in the sliding groove. The limiting component blocks the belly part of the UAV to limit the horizontal position of the UAV.

[0008] As a preferred embodiment of the present invention, the limiting component includes a pressing base plate, a second spring, and an upper housing. The pressing base plate is slidably installed in the sliding groove. The second spring is symmetrically installed on the upper surface of the pressing base plate. The end of the second spring is connected to the inner wall of the sliding groove. The upper housing is equidistantly installed on the pressing base plate. The pressing trapezoidal plate is installed inside the upper housing. The bottom end of the pressing trapezoidal plate is installed with a third spring. The other end of the third spring is connected to the inner wall of the upper housing.

[0009] As a preferred embodiment of the present invention, the partial extrusion trapezoidal plate is in contact with the belly of the drone, causing the extrusion trapezoidal plate to retract into the upper shell, while the remaining part of the extrusion trapezoidal plate pops out and the side wall of the extrusion trapezoidal plate fits against the end of the drone, thus defining the end position of the drone.

[0010] As a preferred technical solution of the present invention, it also includes a protective mechanism, which includes a protective cover, a rotating frame, and a rotating gear. The rotating frame is rotatably mounted on the placement platform. A protective cover for shielding and protecting the wing part of the UAV is installed on the outside of the rotating frame. The rotating gear is mounted on the rotating frame. A transmission gear is meshed on the side of the rotating gear. The transmission gear is rotatably connected to a sliding groove. A movable toothed plate is meshed on the side of the transmission gear. The movable toothed plate is connected to the end of the extrusion block. The lifting and lowering of the extrusion block drives the movable toothed plate to lift and lower synchronously.

[0011] As a preferred embodiment of the present invention, the placement platform includes a lower housing, a baffle, and a partition. The lower housing is installed on one side of the upper surface of the mobile frame, and the baffle is symmetrically installed on the lower housing. The partition is installed on the upper surface of the lower housing and on the side of the baffle. A support platform is installed on the upper surface of the lower housing and between the baffles. Buffer pads are symmetrically installed on the upper surface of the support platform. The buffer pads are in contact with the belly of the drone to protect the belly of the drone. A blocking block is installed at one end of the support platform and is in contact with the drone.

[0012] As a preferred embodiment of the present invention, a mating groove is formed between the baffle and the partition plate, and the flipped protective cover enters the mating groove to seal and shield the drone placed on the support platform.

[0013] As a preferred embodiment of the present invention, a placement groove is formed between the partition plate and the support platform. The drone support frame enters the placement groove, and the limiting block penetrates the side wall of the partition plate and enters the placement groove to squeeze the drone support frame to limit the vertical position of the drone.

[0014] As a preferred embodiment of the present invention, the power supply component includes a battery, a connector, and a mounting block. The battery is installed inside the platform, and the connector is connected to the battery. The connector is connected to the charging interface of the drone to enable charging of the drone. The mounting block is installed on the side wall of the platform.

[0015] As a preferred embodiment of the present invention, the control system includes a console, a data receiving module, and a data analysis module. The console collects data collected by the UAV and then transmits the data to the data analysis module through the data receiving module. The data analysis module analyzes the data, and the analyzed data, along with the source file, is transmitted to the data storage module. The data storage module stores the analyzed file and the source file together.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the establishment of a power supply component and a limiting mechanism enables stable compression and fixation of the drone's position. The use of a compression trapezoidal plate, in conjunction with the blocking block in the placement platform, compresses and fixes the drone's horizontal position. The use of the limiting block in conjunction with the placement platform limits the drone's vertical position, achieving stable installation and ensuring the drone's stability on the placement platform. This facilitates subsequent stable power supply to the drone and allows for easy movement of the entire drone by the mobile frame. The control system collects and analyzes the data gathered by the drone, storing the analyzed data along with the source file. This allows the drone to release its own memory and enables stable cable inspection, improving the stability and work quality during drone inspections. Attached Figure Description

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0029] like Figure 1 The diagram shows the structure of a mobile ground workstation for UAV inspection of power transmission lines in this embodiment. This mobile workstation can collect data from the UAV after its initial inspection, provide power to the UAV to improve its battery life, and collect video footage from the UAV, freeing up storage space for subsequent, more precise cable inspections. The mobile workstation includes a mobile frame 1, a control system 2, and a placement platform 3. The control system 2 is mounted on one side of the upper surface of the mobile frame 1, and the placement platform 3 is mounted on the other side. The control system 2 receives and collects data from the UAV, and the placement platform 3 is equipped with a power supply unit. 4. The power supply unit 4 charges the drone when its battery is depleted, and the placement platform 3, in conjunction with the power supply unit 4, can provide separate power to the drone's battery, facilitating high-frequency inspection operations. The placement platform 3 is equipped with a limiting mechanism 5 to limit the drone's movement. The limiting mechanism 5 mounts the drone on the placement platform 3, allowing the power supply unit 4 to stably charge the drone and also facilitating the movement of the drone by the mobile frame 1. Since the existing cable inspection drones are large in size, operators cannot easily move them. The combination of the mobile frame 1 and the placement platform 3 can extend the drone's endurance and facilitate easy movement of the drone when it is in standby mode.

[0030] The control system 2 in this embodiment mainly consists of a console 21, a data receiving module 22, and a data analysis module 23. The console 21 receives the data collected by the UAV, and then the data is transmitted to the data analysis module 23 through the data receiving module 22. The data analysis module 23 analyzes the data, identifies the damaged parts on the cable, and after inspection, inputs the data into the data storage module 24 through the console 21 to complete the storage and collection of data, so that the UAV can clear the data it has collected and retake the picture.

[0031] As attached Figure 2As shown, this is a schematic diagram of the placement platform 3 in this embodiment. The placement platform 3 includes a lower housing 31, a baffle 32, and a partition plate 33. The lower housing 31 is installed on the upper surface of the mobile frame 1. The baffle 32 is symmetrically installed on the top of the lower housing 31. The partition plate 33 is installed on the surface of the lower housing 31 and on the side of the baffle 32. A mating groove is formed between the baffle 32 and the partition plate 33. A support platform 34 is installed on the upper surface of the lower housing 31 and between the partition plates 33. A placement groove for placing the support frame of the drone is formed between the partition plate 33 and the support platform 34. A buffer pad 35 is installed on the surface of the support platform 34. The buffer pad 35 buffers and protects the belly part of the drone. A blocking block 36 is installed at the end of the partition plate 33 to block one side of the drone. In use, the drone is placed on the upper surface of the partition plate 33. At this time, the support frame of the drone enters the placement groove. The blocking block 36 fits against one end of the drone, and the position of the drone is initially positioned, which facilitates the subsequent stable movement of the drone by the mobile frame 1.

[0032] As attached Figure 3 As shown, this is a structural schematic diagram of the power supply component 4 in this embodiment. The power supply component 4 includes a battery 41, a connector 42, and a mounting block 43. The battery 41 is installed inside the lower housing 31. The end of the battery 41 is electrically connected to the connector 42. The end of the connector 42 is connected to the drone charging interface. The mounting block 43 is installed on the side wall of the lower housing 31. The mounting block 43 limits the laying trajectory of the connector 42. In use, the drone charging operation is completed by connecting the connector 42 to the drone charging interface or the drone battery interface.

[0033] As attached Figure 4The diagram shows the structure of the limiting mechanism 5 in this embodiment. The limiting mechanism 5 includes an electric push rod 51, an extrusion block 52, and an extrusion side plate 53. A sliding groove is provided on the placement platform 3, and the electric push rod 51 is installed in the sliding groove. The extrusion block 52 is installed at the output end of the electric push rod 51. The extrusion side plates 53 are symmetrically arranged in the sliding groove, and a limiting block 54 is installed on the side wall of the extrusion side plate 53. The limiting block 54 penetrates the side wall of the lower housing 31 and enters the placement groove. First springs 55 are symmetrically installed on both sides of the extrusion side plate 53, and the other end of the first spring 55 is connected to the inner wall of the sliding groove. A limiting component 56 for positioning one end of the drone is installed in the sliding groove and directly above the extrusion block 52. In use, the operation of the electric push rod 51 drives the extrusion block 52 to move closer to the drone. At this time, the extrusion block 52 pushes the extrusion side plate 53 and the limiting component 56. The extrusion side plate 53 pushes the limiting block 54 to move to one side of the placement slot. The lower surface of the limiting block 54 fits against the upper surface of the drone support frame, thereby locking the position of the drone support frame and preventing the drone from swaying up and down on the surface of the placement platform 3 when the moving frame 1 moves the drone. The cooperation of the limiting component 56 and the blocking block 36 limits the position of both ends of the drone, limiting the horizontal movement range of the drone and allowing the drone to be stably stored on the placement platform 3.

[0034] As attached Figure 5 and Figure 6 As shown, this is a schematic diagram of the limiting component 56 in this embodiment. The limiting component 56 includes a pressing base plate 561 and a second spring 562. The pressing base plate 561 is slidably installed in the sliding groove. The second springs 562 are symmetrically installed at both ends of the pressing base plate 561 and are connected to the inner wall of the sliding groove. An upper shell 563 is equidistantly installed on the pressing base plate 561. A pressing trapezoidal plate 564 is slidably installed inside the upper shell 563. A third spring 565 is installed at the bottom end of the pressing trapezoidal plate 564 and is connected to the inner wall of the upper shell 563. In use, as the… The pushing of the extrusion block 52 causes the extrusion base plate 561 to move closer to the drone. At this time, multiple sets of extrusion trapezoidal plates 564 pass through the support platform 34 and fit against the belly of the drone. The part of the extrusion trapezoidal plate 564 that is squeezed by the belly of the drone enters into the upper shell 563 under the action of the third spring 565, while the extrusion trapezoidal plate 564 that is not squeezed pops out directly, allowing the extrusion trapezoidal plate 564 to fit against one end of the drone, limiting the horizontal movement trajectory of the drone, realizing the stable installation of the drone, and assisting in the stable power supply of the drone.

[0035] As attached Figure 7As shown, this is a schematic diagram of the protective mechanism 6 in this embodiment. The protective mechanism 6 includes a protective cover 61, a rotating frame 62, and a rotating gear 63. The rotating frame 62 is rotatably mounted on the partition plate 33. A protective cover 61 is installed on the outside of the rotating frame 62 to shield and cover the top of the drone. A rotating gear 63 is mounted on the rotating frame 62. A transmission gear 64 is meshed on the side of the rotating gear 63. A movable toothed plate 65 is meshed on the side of the transmission gear 64. The end of the movable toothed plate 65 is connected to the extrusion block 52. When extruded... When block 52 rises, the moving toothed plate 65 moves upward synchronously, driving the transmission gear 64 to rotate. With the cooperation of the transmission gear 64 and the rotating gear 63, the rotating frame 62 rotates as a whole, causing the protective cover 61 to close completely, thus shielding the drone on the platform 3 and preventing damage to the drone's wings when the moving frame 1 moves the drone. When the pressing block 52 moves downward, with the cooperation of the rotating gear 63 and the transmission gear 64, the protective cover 61 opens completely, making it easy for the operator to pick up the drone.

[0036] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
