Description

Technical Field

[0001] This application relates to the technical field of drones, and in particular to a charging platform for power line inspection drones. Background Technology

[0002] With the rapid development of drone technology, power line inspection drones have become an important tool for inspecting power facilities. However, drones have limited endurance and often need to return frequently to replace batteries or recharge, which seriously affects inspection efficiency and coverage.

[0003] Currently, the industry mainly addresses this issue by increasing battery capacity or adopting fast-charging technology, but these methods still cannot fully meet the needs of long-term, large-scale inspections. Furthermore, manual battery replacement is not only time-consuming and labor-intensive but also increases operational risks. Therefore, developing a charging platform capable of autonomously charging drones has become an urgent technological need. Utility Model Content

[0004] To facilitate autonomous charging and extended battery life for inspection drones, this application provides a charging platform for power inspection drones.

[0005] The power line inspection drone charging platform provided in this application adopts the following technical solution:

[0006] A charging platform for power line inspection drones includes a charging platform body and a charging docking mechanism. The charging platform body is connected to a power source and provides a stable current. The charging docking mechanism is mounted on the charging platform body and docks with the drone to charge it. The charging docking mechanism includes:

[0007] A fixing clamping assembly is disposed on the main body of the charging station and is used to clamp and position the parked drone.

[0008] A charging head is vertically slidably mounted on the main body of the charging platform. The charging head is provided with multiple sets of charging contacts for charging the drone.

[0009] A telescopic component is provided on the main body of the charging station. The telescopic component is used to drive the charging head to slide and insert or remove the charging contacts on the charging head from the drone.

[0010] By adopting the above technical solution, the drone is placed on the main body of the charging platform, and then the fixing clamping component clamps and positions the drone. Then, the telescopic component drives the charging head to slide, and multiple sets of charging contacts on the charging head are inserted into the drone to charge it. After charging is completed, the telescopic component and the fixing clamping component reset to release the drone from the lock, thereby realizing the fully automatic locking, charging and separation process of the drone, which facilitates the autonomous charging and battery life of the inspection drone.

[0011] Furthermore, the main body of the charging station includes:

[0012] The base is connected to a power source and has a charging system inside. The charging system is used to provide a stable current from the power source and facilitates charging of the drone by multiple sets of charging contacts. The base is used to support and fix the drone's frame.

[0013] A support frame is provided, which is mounted on the base and docks with the bottom of the drone. The bottom of the drone has a protrusion with a charging port at the bottom for charging the drone. The support frame has a positioning hole for placing the protrusion. The diameter of the positioning hole is larger than the diameter of the protrusion and facilitates the initial positioning of the protrusion. The fixing clamping assembly is used to clamp and position the protrusion in the positioning hole.

[0014] By adopting the above technical solution, the base is used to support the drone's frame, and the integrated charging system in the base provides a stable current output to facilitate charging the drone. At the same time, the diameter of the positioning hole on the support frame is larger than the diameter of the protrusion, so that the drone completes the initial positioning on the first landing, significantly shortening the time for the drone to accurately align itself.

[0015] Furthermore, the fixing clamping assembly includes:

[0016] Clamping blocks, two sets of clamping blocks are slidably disposed on the support frame in a direction that moves closer or further away from each other, and clamp or unlock the protruding sidewall;

[0017] A double-headed clamping cylinder is mounted on a support frame and is used to drive the clamping block to slide.

[0018] By adopting the above technical solution, the dual-head clamping cylinder synchronously drives two sets of clamping blocks to clamp and position the protrusion, achieving stable mechanical locking, which facilitates the subsequent insertion of the charging head into the drone for charging.

[0019] Furthermore, multiple sets of docking guide rails are arranged in a circumferential array on the inner wall of the positioning hole. These multiple sets of docking guide rails are inclinedly arranged on the inner wall of the positioning hole and are used to guide the protrusion to the axial direction of the positioning hole.

[0020] By adopting the above technical solution, after the protrusion is immersed in the positioning hole, a self-correcting guiding surface is formed by the inclined docking guide rail, so that even if the UAV lands with a certain deviation, it can still automatically slide to the center of the positioning hole axis, thus improving the positioning accuracy of the UAV.

[0021] Furthermore, the protrusion has a frustum structure and the diameter of the end away from the support frame is smaller than the diameter of the end near the support frame. The clamping block on the side near the protrusion matches the side wall of the protrusion. When the two sets of clamping blocks clamp the protrusion, the drone is driven to press against the base.

[0022] By adopting the above technical solution, the truncated cone-shaped protrusion matches the inclined surface of the wedge-shaped clamping block, thereby generating a vertical downward force when the protrusion is clamped, which forces the drone to stick tightly to the base, eliminates micro-vibrations during the charging process, and ensures the stability of current transmission.

[0023] Furthermore, a buffer assembly is provided at the bottom of the charging head, the buffer assembly comprising:

[0024] A connecting block is slidably mounted on a support frame and connected to a telescopic component. A sliding groove is provided on the connecting block. A sliding platform is coaxially provided at the bottom of the charging head. The diameter of the sliding platform is larger than the diameter of the charging head. The sliding platform is slidably mounted in the sliding groove.

[0025] A limiting ring is provided on the connecting block and is used to prevent the sliding table from sliding out of the sliding groove;

[0026] A compression spring is disposed between the sliding groove and the bottom of the sliding table and is used to push the sliding table to slide away from the bottom of the sliding groove.

[0027] By adopting the above technical solution, the sliding table and compression spring set in the sliding groove form an elastic floating joint, so that when the telescopic component drives the connecting block to slide, the compression spring absorbs part of the impact force caused by the position deviation, which improves the plugging and mating efficiency of the charging contact and the charging port. At the same time, the limiting ring prevents excessive positioning and reduces the probability of the charging contact breaking.

[0028] Furthermore, a safety component is provided on the connecting block, the safety component including:

[0029] A trigger rod is disposed on the bottom of the sliding table and passes through the connecting block, and the axis of the trigger rod is parallel to the sliding direction of the sliding table.

[0030] A trigger button is located on the bottom of the connecting block. When the sliding table slides towards the bottom of the sliding groove, it drives the trigger rod to press the trigger button.

[0031] An alarm is mounted on a base and electrically connected to a trigger button, which activates the alarm when pressed.

[0032] By adopting the above technical solution, the trigger rod and the trigger button form a hard limit linkage, so that when the abnormal resistance is too large, an alarm will be triggered and the power supply of the telescopic component will be cut off, reducing the probability of damage caused by collision.

[0033] Furthermore, a protective tube is provided on the connecting block, and the trigger rod is slidably disposed inside the protective tube. The protective tube is used to limit the maximum distance the trigger rod can slide in the direction of the trigger button.

[0034] By adopting the above technical solution, the protective tube limits the travel of the trigger rod, ensuring that the pressing pressure of the trigger rod on the trigger button is within a safe range, thus reducing the probability of the trigger rod being overloaded and damaging the trigger button.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. During the drone's descent, the frustum-shaped protrusion on its bottom is initially positioned by positioning holes, guided by multiple sets of docking guide rails, and clamped and locked by two sets of clamping blocks, gradually improving the protrusion's positioning accuracy. At the same time, the clamping blocks match the sidewalls of the frustum-shaped protrusion, generating a downward force during the clamping process, forcing the drone's support to press against the base. This significantly improves the drone's parking accuracy and stability. Finally, the telescopic component drives the charging head to move vertically upward, precisely inserting the multiple sets of charging contacts on the top into the charging port, thus achieving automatic charging. After charging is completed, the telescopic component moves the charging head away from the drone and releases the clamping blocks from fixing the protrusion, thereby facilitating the inspection drone's autonomous charging and recharge.

[0037] 2. By using a compression spring to push the sliding table against the limiting ring under normal conditions, the charging head and the connecting block move synchronously and have a certain degree of elastic floating function. If the charging contact is accurately aligned with the charging port, the contact can be inserted without obstruction. If there is a deviation or foreign object blocking the charging head, the upward movement of the charging head will be obstructed, causing the sliding table to squeeze the compression spring and drive the trigger rod to press down the trigger button, ultimately cutting off the power of the telescopic component and activating the alarm. This absorbs the impact and effectively prevents the equipment from being damaged by hard collisions. Attached Figure Description

[0045] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0046] This application discloses a charging platform for power line inspection drones.

[0047] Example 1

[0048] Reference Figure 1 The power inspection drone charging platform includes a charging platform body 1 and a charging docking mechanism 4. The charging platform body 1 is connected to a power source and is used to provide a stable current. The charging docking mechanism 4 is set on the charging platform body 1 and docks with the drone to charge the drone.

[0049] Reference Figure 2 and Figure 3 The charging station body 1 includes a base 11 and a support frame 12. The base 11 is connected to a power source and has a charging system inside. The charging system is used to provide a stable current to the power source, thereby facilitating the charging of the drone. The base 11 is used to support and fix the drone stand. The support frame 12 is fixedly installed on the upper surface of the base 11 and docks with the bottom of the drone. The bottom of the drone has a protrusion 2, and the bottom of the protrusion 2 has a charging port for charging the drone. The charging system in this embodiment is the charging system of a conventional drone charging station. That is, charging begins after docking with the drone charging port, and automatically enters protection mode after charging is completed until the connection with the drone charging port is disconnected.

[0050] Reference Figure 2 and Figure 4The support frame 12 has a positioning hole 121 for placing the protrusion 2. The diameter of the positioning hole 121 is larger than the diameter of the protrusion 2, so as to facilitate the initial positioning of the protrusion 2. Multiple sets of docking guide rails 3 are arranged in a circular array on the inner wall of the positioning hole 121. The multiple sets of docking guide rails 3 are installed at an angle on the inner wall of the positioning hole 121. The multiple sets of docking guide rails 3 work together to guide the protrusion 2 in the axial direction of the positioning hole 121. The diameter of the circular space formed at the bottom of the multiple sets of docking guide rails 3 is larger than the diameter of the protrusion 2, so as to guide the position of the protrusion 2 during the drone's parking process, thereby improving the accuracy of the drone's parking position.

[0051] Reference Figure 2 and Figure 4 The charging docking mechanism 4 includes a fixed clamping assembly 41, a charging head 42, and a telescopic component 43. The fixed clamping assembly 41 is mounted on the support frame 12. The fixed clamping assembly 41 is used to clamp and position the parked drone. The fixed clamping assembly 41 includes a clamping block 411 and a double-headed clamping cylinder 412. There are two sets of clamping blocks 411. The two pairs of clamping blocks 411 are symmetrically arranged. The two sets of clamping blocks 411 are slidably mounted on the support frame 12 in a direction that approaches or moves away from each other. The clamping block 411 is used to clamp or unlock the side wall of the protrusion 2. The double-headed clamping cylinder 412 is fixedly installed on the support frame 12. The double-headed clamping cylinder 412 is used to drive the two sets of clamping blocks 411 to slide simultaneously. The protrusion 2 on the drone is a frustum structure. The diameter of the end of the protrusion 2 away from the support frame 12 is smaller than the diameter of the end closer to the support frame 12. The two sets of clamping blocks 411 are matched with the outer wall of the protrusion 2 on the side closer to the protrusion 2. Since the outer wall of the protrusion 2 is an inclined structure, the two sets of clamping blocks 411 exert a downward force on the protrusion 2 when clamping it, thereby driving the drone to press against the base 11.

[0052] Reference Figure 2 and Figure 4 The charging head 42 is vertically slidably mounted on the charging platform body 1. The charging head 42 is provided with multiple sets of charging contacts 421. The multiple sets of charging contacts 421 on the charging head 42 are inserted into the charging port of the drone to complete the connection between the charging system and the drone, and finally facilitate the charging of the drone. The telescopic member 43 is provided on the support frame 12. The telescopic member 43 is used to drive the charging head 42 to slide and insert or remove the charging contacts 421 on the charging head 42 into or out of the charging port of the drone. In this embodiment, the telescopic member 43 can be a cylinder, hydraulic cylinder, electric telescopic rod or other device with linear telescopic function. In order to improve its telescopic stability, the support frame 12 is also provided with guide posts to facilitate the sliding of the charging head 42.

[0053] Reference Figure 4Specifically, during the drone's parking process, the protrusion 2 first enters the positioning hole 121 for initial positioning. Then, as the drone descends and its support is placed on the base 11, multiple sets of docking guide rails 3 provide common guidance, thereby improving the accuracy of the protrusion 2's position. Then, the drone's power system is turned off, and the double-headed clamping cylinder 412 is activated, causing the two sets of clamping blocks 411 to clamp and fix the protrusion 2, achieving the final positioning of the protrusion 2. This further improves the accuracy of the protrusion 2's position and reduces the probability of the telescopic component 43 pushing the charging head 42 upwards during the insertion of the charging port.

[0054] The working principle of Embodiment 1 of this application is as follows:

[0055] During the drone's descent, the frustum-shaped protrusion 2 on its bottom is initially positioned by the positioning hole 121, guided by multiple sets of docking guide rails 3, and clamped and locked by two sets of clamping blocks 411, gradually improving the positioning accuracy of the protrusion 2. At the same time, the clamping blocks 411 match the side wall of the frustum-shaped protrusion 2, so that the clamping process generates a downward force, forcing the drone support to press against the base 11, thereby significantly improving the drone's parking accuracy and stability. Finally, the telescopic component 43 drives the charging head 42 to move vertically upward, accurately inserting the multiple sets of charging contacts on the top into the charging port, thereby realizing automatic charging. When charging is completed, the telescopic component 43 moves the charging head 42 away from the drone and releases the clamping blocks 411 from clamping and fixing the protrusion 2, thereby facilitating the inspection drone's autonomous charging and recharge.

[0056] Example 2

[0057] Reference Figure 5 and Figure 6The difference between this embodiment and embodiment 1 is that a buffer assembly 5 is provided at the bottom of the charging head 42. The buffer assembly 5 includes a connecting block 51, a limiting ring 52, and a compression spring 53. The connecting block 51 is slidably mounted on the support frame 12 and is connected to the telescopic member 43. A sliding groove 511 is provided on the connecting block 51. A sliding platform 422 is coaxially fixedly mounted at the bottom of the charging head 42. The diameter of the sliding platform 422 is larger than the diameter of the charging head 42. The sliding platform 422 is slidably mounted in the sliding groove 511. A through hole is provided at the center of the bottom of the connecting block 51. The cable inside the charging head 42 passes through the sliding platform 422 and the connecting block 53 in sequence. Block 51 is electrically connected to the charging system; a limiting ring 52 is fixedly installed on the connecting block 51 by bolts, and the limiting ring 52 is used to prevent the sliding platform 422 from sliding out of the sliding groove 511; a compression spring 53 is disposed between the sliding groove 511 and the bottom of the sliding platform 422, and the compression spring 53 is used to push the sliding platform 422 to slide away from the bottom of the sliding groove 511 and press against the bottom of the limiting ring 52, and the compression spring 53 is sleeved on the cable; the base 11 of this embodiment has a receiving groove to facilitate the stretching or storage of the cable when the charging head 42 is extended or retracted, thereby reducing the impact of the cable on the compression spring 53 and the connecting block 51.

[0058] Reference Figure 5 and Figure 6 A safety component 6 is provided on the connecting block 51. The safety component 6 includes a trigger rod 61, a trigger button 62, and an alarm 63. The trigger rod 61 is fixedly installed on the bottom of the sliding table 422 and passes through the connecting block 51. The axis of the trigger rod 61 is parallel to the sliding direction of the sliding table 422. The trigger button 62 is fixedly installed on the bottom of the connecting block 51. When the sliding table 422 slides towards the bottom of the sliding groove 511, it drives the trigger rod 61 to slide towards the trigger button 62 and finally presses the trigger button 62, thereby activating the trigger button 62. The alarm 63 is fixedly installed on the base 11 and is electrically connected to the trigger button 62. The alarm 63 is activated after the trigger button 62 is pressed into place. In this embodiment, when the trigger button 62 is activated, it closes the telescopic member 43 through an electrical signal to avoid damaging the charging head 42 and its internal charging contacts 421.

[0059] Reference Figure 6 A protective tube 7 is fixedly installed on the connecting block 51. The axis of the protective tube 7 coincides with the axis of the trigger rod 61. The trigger rod 61 is slidably installed inside the protective tube 7. The protective tube 7 is used to limit the maximum distance that the trigger rod 61 slides in the direction of the trigger button 62. When the trigger rod 61 slides in the protective tube 7 and slides to the maximum displacement in the direction of the trigger button 62, and the trigger button 62 is pressed into place, the protective tube 7 prevents the trigger rod 61 from continuing to slide in the direction of the trigger button 62, thereby reducing the probability of the trigger rod 61 being over-pressed on the trigger button 62 and causing damage to the trigger button 62.

[0060] Reference Figure 5 and Figure 6 Specifically, after the two sets of clamping blocks 411 fix the protrusion 2, the telescopic component 43 is activated, which in turn drives the connecting block 51 to slide. The compression spring 53 fixes the charging head 42 inside the connecting block 51 and slides with the connecting block 51. When the charging contact 421 on the charging head 42 is aligned with the charging port and there are no obstructions, the compression spring 53 makes the charging contact 421 stably inserted into the charging port, improving charging stability. However, when the charging contact 421 on the charging head 42 is not aligned with the charging port or there are obstructions, the compression spring 53 is compressed as the connecting block 51 slides, which finally causes the trigger rod 61 to press the trigger button 62 and activate the trigger button 62, thereby closing the telescopic component 43. Then the alarm 63 sounds an alarm, which is convenient for staff to check and repair.

[0061] The working principle of Embodiment 2 of this application is as follows:

[0062] The compression spring 53 normally pushes the sliding table 422 to press against the limiting ring 52, so that the charging head 42 and the connecting block 51 move synchronously and have a certain elastic floating function. If the charging contact 421 is aligned with the charging port accurately, the contact can be inserted without obstruction. If there is a deviation or foreign object blocking it, the upward movement of the charging head 42 will be blocked, causing the sliding table 422 to squeeze the compression spring 53 and drive the trigger rod 61 to press down the trigger button 62, which will eventually cut off the power of the telescopic part 43 and activate the alarm 63, thereby absorbing the impact and effectively preventing the equipment from being damaged by hard collision.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
