Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and more specifically, to a transfer charging base for unmanned aerial vehicle endurance and a method for using the same. Background Art

[0002] The distribution network is an electric power network that distributes power locally or step by step according to voltage to various users through distribution facilities. It is composed of overhead lines, cables, poles, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities. It plays an important role in distributing electric energy in the power grid. Due to the large scale of transmission lines, wide coverage and complex terrain environment, regular inspections of the lines are required. With the gradual promotion and application of drones and the improvement of inspection efficiency and accuracy, a new inspection mode has been opened - drone smart inspection, which comprehensively improves inspection efficiency, helps teams reduce burdens and increase efficiency, and promotes the digital transformation of distribution network inspections.

[0003] Due to the large scale of power transmission lines, wide coverage, and complex terrain environments, the flight routes of drones are relatively long. Compared with existing drones, the endurance and charging of drones have become issues of concern. Patent No. CN111746815A, a charging base and method for unmanned on-site monitoring drones, includes a helipad, a monitoring drone, a control cabin, a sunshade, a limit device, and a solar photovoltaic panel.

[0004] In the above scheme, the monitoring drone can be automatically charged when it is parked on the helipad, the limit device can prevent the monitoring drone from moving, and the solar photovoltaic panel can use solar energy to generate electricity, which is used as electricity for the operation of the charging device. However, during use, since the helipad is located at the bottom of the sunshade, the flying space of the drone is small, and the accuracy of existing drones in remote landing is relatively low. When the drone lands or takes off, it will cause turbulence in the airflow around the drone, which is easy to cause collisions and affect the flight of the drone. In addition, when the drone stays on the helipad to charge, the drone cannot continue to patrol, resulting in low work efficiency. Summary of the invention

[0021] S3: The charging base controls the first electric telescopic rod to extend, so that the fixed plate is unfolded to both sides of the charging base.

The drone returns according to the inspection task, or continues to the next tower for charging and flying.

[0025] Technical effects and advantages of the present invention:

[0026] 1. The present invention sets a first electric telescopic rod to extend before the drone lands, so that the fixing plate moves to both sides. When the drone lands on the surface of the charging base, the first electric telescopic rod is extended and retracted, so that the limit rods at both ends synchronously move the drone towards each other, thereby limiting the drone and moving the drone to the middle of the charging base, which is convenient for the drone to land. At the same time, it makes up for the defect of insufficient landing accuracy of the drone.

[0027] 2. The present invention provides a space for the landing of the drone by setting up a solar panel that is independent of the charging base. The charging base is connected to the solar panel and municipal electricity respectively, and a variety of power supply methods are used to compensate for the defect that the solar panel may provide insufficient power.

[0028] 3. The present invention provides a buffer device so that when the drone lands on the surface of the contact plate at one end of the charging base, the sleeve block descends inside the movable groove, causing the damping block to press down on the surface of the positioning rod. Through the deformation of the damping block and the restoring force of the buffer spring, the contact plates on both sides fit onto the landing point of the drone, thereby reducing shock to the drone and preventing the drone from contacting hard objects on the charging base and causing collisions that affect the landing of the drone.

[0029] 4. The present invention fixes the drone by setting a rotating card block to rotate upward. At the same time, the extended movable rod limits the reverse rotation of the rotating card block. Combined with the L-shape of the rotating card block itself, the drone is effectively fixed to prevent the drone from falling on the surface of the charging base. In the process of unfolding the rotating card block, the baffle is moved out from the top of the charging compartment, so that the wireless charging seat inside the charging compartment is displayed, showing the receiving state, thereby improving the receiving efficiency of the device.

[0030] 5. The present invention controls the wireless charging seat to rise by setting a second electric telescopic rod, and contacts the receiving coil end at the bottom of the drone. At this time, the bottom frame is located at the bottom of the drone, the electromagnet stops working, and loses magnetic attraction with the magnet block. The reset spring resets, so that the card rod is connected to the bottom of the drone, and the fixed card block is separated from the inside of the card plate, and the wireless charging seat is connected to the bottom of the drone. At this time, the drone drives the wireless charging seat to continue flying, realizing charging and inspection at the same time, saving charging waiting time, and greatly improving the inspection efficiency of the drone.

[0044] A solar panel 3 is provided and is independent of the charging base 4 to provide space for the landing of the drone, and the charging base 41 is respectively connected to the solar panel 3 and municipal electricity, and a variety of power supply methods are used to compensate for the defect that the solar panel 3 may have insufficient power supply.

[0045] Before the drone lands, the first electric telescopic rod 45 is extended to move the fixing plate 46 to both sides. When the drone lands on the surface of the charging base 41, the first electric telescopic rod 45 is extended and retracted to make the limiting rods 47 at both ends move the drone towards each other synchronously, thereby limiting the position of the drone and moving the drone to the middle of the charging base 41.

[0046] As attached Figure 4As shown, the fixing device 5 includes two bidirectional motors 51, and the two bidirectional motors 51 are respectively fixedly installed on both sides of the top of the charging base 41 near the fixed plate 46. A bidirectional screw 52 is arranged inside the bidirectional motor 51, and the outer surfaces of both ends of the bidirectional screw 52 are threadedly connected to a moving frame 53, and the two adjacent sides of the two moving frames 53 are fixedly connected with a baffle 58, and the outer surface of the baffle 58 is fixedly connected with a sealing strip 57, and a sealing gasket 56 is fixedly connected at the connection between the baffle 58 and the moving frame 53, and the two ends of the moving frame 53 away from the side are fixedly connected with a connecting block 54, and the side of the connecting block 54 is rotatably installed with a rotating clamping block 55, and the rotating clamping block 55 is L-shaped.

[0047] When the connecting block 54 and the rotating block 55 slide on the top of the connecting frame 43 through the movable frame 53, the rotating block 55 is prevented from falling due to gravity when it moves out of the charging base 41. Therefore, when the movable rod 44 is extended by the electric telescopic drive 42, the ball 48 hits one side of the rotating block 55, causing the rotating block 55 to rotate on the side of the connecting block 54. The rotating block 55 rotates upward to fix the drone. At the same time, the extended movable rod 44 limits the reverse rotation of the rotating block 55, and the L-shape of the rotating block 55 itself effectively fixes the drone to prevent the drone from falling on the surface of the charging base 41.

[0048] In addition, the sealing strip 57 and the sealing gasket 56 squeeze each other when the baffle 58 moves toward each other, thereby sealing the top of the charging compartment 410 to prevent the interior of the charging compartment 410 from being affected by the environment such as rain, thereby affecting the service life of the wireless charging stand 411.

[0049] Among them, the baffle 58 is slidably installed on the top of the charging compartment 410, the movable frame 53 is slidably installed on both sides of the upper end of the charging base 41, the connecting block 54 and the rotating card block 55 are slidably sleeved on both sides of the charging base 41, and the connecting block 54 and the rotating card block 55 are both slidably installed on the top of the connecting frame 43.

[0050] As attached Figure 5 As shown, the buffer device 6 includes a contact plate 61 and a positioning rod 64, the positioning rod 64 is fixedly installed at the two ends of the bottom of the base groove 412, the bottom of the contact plate 61 is fixedly connected with a sleeve block 62, both sides of the bottom of the sleeve block 62 are fixedly connected with damping blocks 63, the sleeve block 62 and the damping block 63 are both movably sleeved on the outer surface of the positioning rod 64, the outer surface of the positioning rod 64 is movably sleeved with a buffer spring 65, the two ends of the buffer spring 65 are respectively fixedly connected to the bottom of the damping block 63 and the positioning rod 64, and the sleeve block 62 is movably sleeved inside the movable groove 49.

[0051] When the UAV lands on the surface of the contact plate 61 at one end of the surface of the charging base 41 by using the buffer device 6, the socket block 62 descends inside the movable groove 49, causing the damping block 63 to press down on the surface of the positioning rod 64. Through the deformation of the damping block 63 and the restoring force of the buffer spring 65, the contact plates 61 on both sides fit onto the landing point of the UAV, thereby reducing the shock of the UAV and preventing the UAV from contacting hard objects, causing collisions and affecting the landing of the UAV.

[0052] Among them, positioning slots 4102 are opened at both ends of the inner wall of the charging compartment 410, the bottom of the charging compartment 410 is fixedly connected to the multi-stage electric telescopic rod 4101, the top of the multi-stage electric telescopic rod 4101 is fixedly connected to the clamping plate 4103, fixed slots 4106 are opened on both sides of the clamping plate 4103, the top of the clamping plate 4103 is fixedly connected to the charging plug 4104, and the two sides of the inside of the clamping plate 4103 are fixedly connected to the electromagnet 4105.

[0053] This embodiment provides a transfer charging base for drone endurance, which includes the following steps: Step 1: a solar panel 3 and a charging base 4 are installed on each tower 1 on the route that needs to be inspected through a fixing frame 2;

[0054] Step 2: The operator remotely controls the drone to inspect the route. When the drone runs out of power, a signal is fed back to the operator. The operator finds the nearest tower 1 according to the drone's flight location and remotely controls the charging base 41.

[0055] Step 3: The charging base 41 controls the first electric telescopic rod 45 to extend, so that the fixed plate 46 is unfolded to both sides of the charging base 41. At the same time, the bidirectional motor 51 is started to control the bidirectional screw 52 to rotate, so that the moving frame 53 moves to both sides of the charging base 41, and the baffle 58 is moved out from the top of the charging compartment 410, so that the wireless charging seat 411 inside the charging compartment 410 is displayed, showing the receiving state;

[0056] Step 4: When the drone stays on the surface of the charging base 41, the first electric telescopic rod 45 is retracted, the fixing plate 46 approaches the charging base 41, and the limiting rod 47 limits and fixes the two ends of the drone. Then, the electric telescopic drive 42 is started to extend the movable rod 44. When the ball 48 contacts one end of the rotating block 55, the rotating block 55 rotates at one end of the connecting block 54, and the rotating block 55 is clamped on the other two sides of the drone.

[0057] Step 5: During charging, the second electric telescopic rod 413 controls the wireless charging seat 411 to rise and contact the receiving coil end at the bottom of the drone to wirelessly charge the drone.

[0058] The working principle of the present invention is as follows: a solar panel 3 and a charging base 4 are installed on each pole tower 1 on the route that needs to be inspected through a fixing frame 2. The operator remotely controls the UAV to inspect on the route. When the UAV is low on power, a signal is fed back to the operator. The operator finds the nearest pole tower 1 according to the flying position of the UAV and remotely controls the charging base 41. The charging base 41 controls the extension of the first electric telescopic rod 45 to expand the fixing plate 46 to both sides of the charging base 41. At the same time, the bidirectional motor 51 is started to control the rotation of the bidirectional screw 52 to move the moving frame 53 to both sides of the charging base 41. The baffle 58 is moved out from the top of the charging compartment 410 to display the wireless charging seat 411 inside the charging compartment 410, presenting a pick-up state. The UAV When staying on the surface of the charging base 41, the first electric telescopic rod 45 is retracted, the fixed plate 46 approaches the charging base 41, and the limit rod 47 limits and fixes the two ends of the drone. Then, the electric telescopic drive 42 is started to extend the movable rod 44. When the ball 48 contacts one end of the rotating block 55, the rotating block 55 rotates at one end of the connecting block 54, and the rotating block 55 is connected to the other two sides of the drone. The second electric telescopic rod 413 controls the wireless charging seat 411 to rise and contact the receiving coil end at the bottom of the drone to wirelessly charge the drone. After the end, the drone flies, and the above structure moves in the opposite direction and automatically recovers. At this time, the solar panel 3 or municipal electricity charges the energy storage battery inside the charging base 41 again.

[0063] The present embodiment provides a transfer charging base for drone endurance, comprising the following steps: Step 1: A solar panel 3 and a charging base 4 are installed on each pole tower 1 on the route to be inspected through a fixing frame 2. In order to make up for the shortcoming that wireless charging needs to wait, which leads to reduced inspection efficiency, wireless charging seats 411 are placed inside the charging bases 4 on multiple pole towers 1 at intervals, so that only one of the two adjacent pole towers 1 has a wireless charging seat 411;

[0064] Step 2: The operator remotely controls the drone to inspect the route. When the drone runs out of power, a signal is fed back to the operator. The operator finds the nearest tower 1 according to the drone's flight location and remotely controls the charging base 41.

[0065] Step 3: The charging base 41 controls the first electric telescopic rod 45 to extend, so that the fixed plate 46 is unfolded to both sides of the charging base 41. At the same time, the bidirectional motor 51 is started to control the bidirectional screw 52 to rotate, so that the moving frame 53 moves to both sides of the charging base 41, and the baffle 58 is moved out from the top of the charging compartment 410, so that the wireless charging seat 411 inside the charging compartment 410 is displayed, showing the receiving state;

[0066] Step 4: When the drone stays on the surface of the charging base 41, the first electric telescopic rod 45 is retracted, the fixing plate 46 approaches the charging base 41, and the limiting rod 47 limits and fixes the two ends of the drone. Then, the electric telescopic drive 42 is started to extend the movable rod 44. When the ball 48 contacts one end of the rotating block 55, the rotating block 55 rotates at one end of the connecting block 54, and the rotating block 55 is clamped on the other two sides of the drone.

[0067] Step 5: During charging, the second electric telescopic rod 413 controls the wireless charging seat 411 to rise and contact the receiving coil end at the bottom of the drone. At this time, the bottom frame 4113 is located at the bottom of the drone, the electromagnet 4105 stops working, loses magnetic attraction with the magnet block 02, and the reset spring 05 resets, so that the clamping rod 01 is clamped at the bottom of the drone, and the fixed clamping block 03 is separated from the inside of the clamping plate 4103. At this time, the drone drives the wireless charging seat 411 to continue flying, realizing simultaneous charging and inspection;

[0068] Step 6: When the charging of the drone is finished, or the wireless charging seat 411 needs to be placed, the drone flies to the surface of the charging base 41 without the wireless charging seat 411 inside, and the multi-stage electric telescopic rod 4101 drives the card plate 4103 to rise, so that the charging plug 4104 is inserted into the charging slot 4117, and the electromagnet 4105 generates magnetism to magnetically attract the magnet block 02, so that the fixed card block 03 is carded into the fixed card slot 4106, and the reset spring 05 is compressed, and the multi-stage electric telescopic rod 4101 contracts, so that the wireless charging seat 411 is separated from the drone, and the wireless charging seat 411 enters the interior of the charging compartment 410, and the energy storage battery inside the charging base 41 charges the portable power supply 4112 through the charging slot 4117. The drone returns according to the inspection task, or continues to cruise, and reaches the next tower 1 for charging and flight.

[0069] The working principle of the present invention is as follows: wireless charging seats 411 are placed at intervals inside the charging bases 4 on multiple pole towers 1, so that only one of the two adjacent pole towers 1 has a wireless charging seat 411. The operator remotely controls the drone to inspect on the route. When the drone is low on power, a signal is fed back to the operator. The operator finds the nearest pole tower 1 according to the flying position of the drone and remotely controls the charging base 41.

[0070] The above scheme is used for landing. During charging, the second electric telescopic rod 413 controls the wireless charging seat 411 to rise and touch the receiving coil end at the bottom of the drone. At this time, the bottom frame 4113 is located at the bottom of the drone, and the electromagnet 4105 stops working and loses magnetic attraction with the magnet block 02. The reset spring 05 resets, so that the clamping rod 01 is clamped at the bottom of the drone, and the fixed clamping block 03 is separated from the inside of the clamping plate 4103. At this time, the drone drives the wireless charging seat 411 to continue flying, realizing charging and inspection at the same time. When the drone is finished charging or the wireless charging seat 411 needs to be placed, the drone flies to the surface of the charging base 41 without the wireless charging seat 411 inside, and the multi-stage electric The telescopic rod 4101 drives the card plate 4103 to rise, so that the charging plug 4104 is inserted into the charging slot 4117, and the electromagnet 4105 generates magnetism to magnetically attract the magnet block 02, so that the fixed card block 03 is snapped into the inside of the fixed card slot 4106, and the reset spring 05 is compressed, and the multi-stage electric telescopic rod 4101 contracts, so that the wireless charging seat 411 is separated from the drone, and the wireless charging seat 411 enters the interior of the charging compartment 410, and the energy storage battery inside the charging base 41 charges the portable power supply 4112 through the charging slot 4117. The drone returns according to the inspection task, or continues to cruise, and reaches the next tower 1 for charging and flying.
