Description

Technical Field

[0001] This invention relates to the technical field of warning light mounting devices, specifically to a self-sensing electronically controlled mounting device for drones mounting warning lights and its mounting method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In the operation and maintenance of power transmission and distribution lines, warning lights are installed on the transmission lines so that they can flash at night to remind people of the danger of high-voltage lines and prevent construction machinery from accidentally touching the conductors and causing the line to trip.

[0004] The inventors discovered during their research that current methods for installing warning lights mostly involve live-line working. Workers use insulated bucket trucks or insulated ladders to reach the vicinity of the power lines for installation. This method is extremely risky, cumbersome, inefficient, and costly. Some existing solutions utilize drones for installation. The drone carries the warning light via a mounting bracket. The bracket's mechanical release mechanism causes the warning light's legs to release and encircle the power line upon contact with it. Then, the force exerted by the power line on the warning light pulls it detach from the bracket. However, this method involves stress on the warning light during installation. Failure to release the legs or detachment from the power line increases the probability of installation failure, potentially damaging the warning light. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a self-sensing electronically controlled mounting device and method for mounting warning lights on drones. This device enables the warning light to automatically disengage when it reaches the power transmission line, improving the mounting efficiency of the warning light and reducing the probability of damage due to mounting failure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] One or more embodiments provide a drone-mounted warning light self-sensing electronic control mounting device, including: a bracket body, a balancing device disposed at the end of the bracket body, and an automatic release device;

[0008] The shape of the bracket body is adapted to the shape of the warning light support leg in the open state; the automatic release device includes a fixing component, a sensing sensor and a drive mechanism. The fixing component is used to fix the warning light support leg, and the drive mechanism is controlled in response to the signal from the sensing sensor to drive the fixing component to release the warning light support leg.

[0009] One or more embodiments provide a mounting method for a drone-mounted warning light self-sensing electronic control mounting device based on the above, including the following steps:

[0010] The warning light is mounted on the mounting device, and the sensor is activated after a set delay.

[0011] The drone carries a mounting device on its underside;

[0012] Control the drone to move it above the mounting wire;

[0013] Control the direction and spatial position of the drone so that the power transmission line is within the opening of the bracket body of the mounting device;

[0014] The system acquires signals from the sensing sensors. When a signal is detected, the servo motor releases the two outriggers of the warning light in chronological order.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In this disclosure, an induction sensor is set to detect whether the warning light has reached the installation position. The drive mechanism is controlled based on the induction signal. The drive mechanism releases the warning light support leg, thus realizing the automated electronic control mounting of the warning light.

It should be noted that, without conflict, the various embodiments and features within those embodiments can be combined with each other. The embodiments will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] In one or more of the technical solutions disclosed in the embodiments, such as Figures 1 to 3 As shown, a drone-mounted warning light self-sensing electronic control mounting device includes: a bracket body 1, a balancing device disposed at the end of the bracket body 1, and an automatic release device.

[0030] The shape of the bracket body 1 is adapted to the shape of the warning light support leg 9-1 in the open state. The automatic release device includes a fixing component 6, a sensing sensor and a drive mechanism. The fixing component is used to fix the warning light support leg 9-1. In response to the signal from the sensing sensor, the drive mechanism is controlled to drive the fixing component to release the warning light support leg 9-1.

[0031] In this embodiment, a sensor is set to detect whether the warning light 9 has reached the installation position. The drive mechanism is controlled based on the sensing signal. The drive mechanism releases the warning light support leg, thus realizing the automated electronic control mounting of the warning light.

[0032] In this embodiment, the warning light 9 includes a light body and warning light legs 9-1 disposed on the light body. The two warning light legs 9-1 can be joined together by a return mechanism. The warning light legs are hung on the power transmission line. Any warning light with a similar structure can be hung using the device of this embodiment, such as the power transmission line warning light disclosed in patent CN 214896821U.

[0033] In some embodiments, the support body 1 may adopt a skeleton structure, and optionally, adopt a V-shaped structure, including two side arms 1-1 set at a set angle. The side arms 1-1 are provided with a sensing sensor and an action component from the connection position to the end. The end of the side arms 1-1 is provided with an outwardly inclined mounting plate 1-5 for fixing the balance device.

[0034] The bracket body 1 can be made of aluminum alloy, with a width of 20mm and a thickness of 3mm.

[0035] In this embodiment, the angle between the mounting plate 1-5 and the center line is greater than the angle between the “V” shaped side arms 1-1 and the center line.

[0036] In some embodiments, a cross arm is provided at the connection of the two side arms 1-1 of the support body 1. The two side arms 1-1 are opened at a set angle and are provided at both ends of the cross arm. A mounting structure for connecting a drone is provided on the cross arm.

[0037] Optionally, the mounting structure for the drone in this embodiment can be configured as a mounting ring 1-4. The mounting ring 1-4 can be connected to the drone using an insulated rope or an insulated rod.

[0038] In some embodiments, the balancing device is configured as a guide rod 8, which is mounted on the mounting plate 1-5 at the end of the side support arm 1-1. The length of the guide rod 8 is greater than the length of the side support arm 1-1. The angle between the guide rod 8 and the center line of the bracket body 1 is greater than the angle between the side support arm 1-1 and the bracket body 1.

[0039] In this embodiment, a guide rod 8 is installed on each side. The guide rod 8 increases the length of the bracket and increases the opening angle, which enables the bracket to maintain a certain balance and reduces the rotation and shaking of the main body. When the transmission line conductor enters the opening formed by the guide rod, the guide rod plays a limiting role. As the special device slides down, the conductor gradually enters the specific hanging position between the two side arms 1-1.

[0040] Optionally, in this embodiment, the diameter of the guide rod 8 can be set to 3mm.

[0041] Specifically, the guide rod 8 is fixed by a guide rod fixing seat 1-3 on the mounting plate 1-5, which presses and fixes the guide rod 8 on the mounting plate 1-5.

[0042] A further technical solution, in order to achieve automatic drive control, is that the electric control mounting device is also equipped with a main control unit 2, which can be fixedly mounted on the side support arm 1-1.

[0043] Optionally, the main control unit 2 includes a main control chip CPU, a power module, a drive circuit, and control switches. The main control chip CPU is connected to the power module, the drive circuit, and the control switches.

[0044] The main control chip (CPU) is connected to the drive mechanism of the automatic tripping device via a drive circuit to output drive signals. In this embodiment, the device battery 3 can be a lithium battery, specifically a 2s lithium battery power battery, where S represents a single cell and 2s represents two cells connected in series.

[0045] The control switch is used to control the start and stop of the main control unit 2, as well as the start and stop of the drive mechanism and the sensing sensor.

[0046] The control switch mainly controls the position of servo motor 7. Initially, servo motor 7 is in the released position, and the foot stop shaft 7-1 connected to servo motor 7 can move freely. At this time, the warning light foot is placed in the mounting position by hand, the stop shaft 7-1 presses down on the foot, and the corresponding control switch is pressed. Servo motor 7 rotates and is in a fixed position. The hand can be released to fix the warning light foot.

[0047] In some embodiments, the sensing sensor of the automatic tripping device can be an infrared sensor or a laser sensor, and the sensing sensor is communicatively connected to the main control unit.

[0048] When in use, if an object passes by the detection end of the infrared sensor or laser sensor, such as a power transmission line, the corresponding signal will be detected.

[0049] In a specific example, this embodiment is configured as a laser sensor, including a laser sensor transmitting unit 4 and a laser sensor receiving unit 5, which are disposed opposite to each other on the two side arms 1-1 of the support body 1.

[0050] In use, the laser emitting unit emits laser beams through the hole on the side arm 1-1, and the laser beam enters the sensing module of the receiving unit 5 through the hole on the side wall, outputting corresponding switching information.

[0051] In some embodiments, the structure of the fixing component 6 of the automatic release device can be as follows: Figure 1 and Figure 2As shown, the fixing component 6 includes a rotating shaft 6-2, through which a rotating plate rotatably mounted on the side support arm 1-1 can be mounted. The rotating plate includes a warning light support leg pressure plate 6-3 and a drive plate 6-1. The rotating plate is fixed and released by the action of the drive mechanism, thereby enabling the fixing and release of the warning light support leg.

[0052] In one specific implementation, a through groove 1-2 is provided on the side support arm 1-1 of the bracket body 1, and a rotating plate is rotatably disposed within the through groove 1-2 via a rotating shaft 6-2. For example, the width of the through groove 1-2 can be set to 3mm. Figure 1 As shown, the thickness of the rotating plate is less than the size of the through groove, the rotating shaft 6-2 is set vertically, and the rotating plate is set horizontally.

[0053] In some embodiments, the drive mechanism may be a servo motor 7, which is electrically connected to the main control unit 2. The main control unit controls the servo motor to rotate at a corresponding angle via a PWM signal.

[0054] Furthermore, a rotatable disc is connected to the power output end of the servo motor 7, and a stop shaft 7-1 is provided on one side of the disc. The stop shaft 7-1 can be fitted with the drive plate 6-1.

[0055] like Figure 2 As shown, when the stop shaft 7-1 and the drive plate 6-1 are in contact, the stop shaft 7-1 presses and fixes the drive plate 6-1 onto the side support arm 1-1. Thus, the other end opposite to the stop shaft 7-1 can press the warning light support leg 9-1 onto the side support arm 1-1. That is, the warning light support leg pressure plate 6-3 presses the warning light support leg 9-1 onto the side support arm 1-1, which can realize the fixation of the warning light on the bracket body 1.

[0056] like Figure 1 As shown, the stop shaft 7-1 and the drive plate 6-1 are in the released state, the stop shaft 7-1 is separated from the drive plate 6-1, the rotating plate is in the released state, and the warning light is detached from the bracket body 1, so it can be mounted. By rotating 7-1 by a specific angle, the opening and closing of the rotating plate of the fixing component 6 can be controlled.

[0057] The above-mentioned method of using the drone-mounted warning light self-sensing electronic control mounting device involves fixing the warning light to the mounting device, and the drone carrying the new warning light through the mounting device. The fixing device has a "V" shaped structure. The drone carries the device and flies above the power line, then slowly descends. The power line enters through the opening of the special device. When the power line enters a specific position, the laser beam emitted by the laser sensor is blocked by the power line, emitting a signal. The main control unit 2 receives the signal and controls the servo motors on both sides to release the spring feet according to a certain logical sequence. The new warning light spring clamps the power line, thereby completing the mounting operation of the new warning light.

[0058] Example 2

[0059] Based on Embodiment 1, this embodiment provides a method for mounting a self-sensing electronic control mounting device for a drone-mounted warning light, as described in Embodiment 1, comprising the following steps:

[0060] Step 1: Hang the warning light on the mounting device and activate the sensor after a set delay.

[0061] Step 2: The drone carries a mounting device on its underside; control the drone to move it above the mounting wire.

[0062] Step 3: Control the movement direction of the drone so that the power transmission line is within the opening of the bracket body 1 of the mounting device;

[0063] Step 4: Obtain the sensor signal. When the sensor is detected, control the servo motor 7 to release the two legs of the warning light in sequence according to the time sequence.

[0064] In this embodiment, the sensor is activated after a delay following the mounting of the warning light, which avoids interference from subsequent actions and improves the stability of the device. Releasing the warning light legs 9-1 in chronological order ensures the warning light can detach smoothly from the mounting device. This avoids the uncertainty caused by simultaneous release from both sides. For example, simultaneous release can be accidental; if the longer side is released slightly faster than the shorter side, the shorter side might not come out, while the longer side snaps in, potentially trapping the leg stop 7-1. In such cases, the mounting device cannot detach from the mounted warning light, and the warning light becomes stuck on the wire, posing a significant danger to the drone.

[0065] In step 1, the warning light is mounted on the mounting device. Specifically:

[0066] Step 11: Connect the mounting device to the drone using a rope or insulated rod;

[0067] Step 12: When the lengths of the warning light legs 9-1 of the warning light 9 are different, first fix the shorter leg to the corresponding side arm 1-1 of the bracket body 1, and then fix the longer leg to the other side arm 1-1 of the bracket body 1.

[0068] The new type of warning light has two spring-loaded legs, a long leg and a short leg, with the short leg able to pass inside the long leg. When the warning light is fixed to the dedicated mounting device, the long and short legs correspond one-to-one with the two arms of the device. First, fix the short leg, place the light body on top of the mounting device, pry open the short leg, and clamp the crossbeam on the spring-loaded short leg through the fixing component 6. Press the corresponding switch, and the main control unit 2 sends a control signal to control the servo motor 7 to lock the rotating plate of the fixing component 6. Then, fix the long leg, pry open the long leg, and press the crossbeam of the spring-loaded long leg through the rotating plate of the fixing component 6. Press the corresponding switch, and the main control unit 2 sends a control signal to control the servo motor 7 to lock the rotating plate of the corresponding fixing component 6.

[0069] In step 1, the sensor can be restarted after a delay of approximately 30 seconds.

[0070] Control the drone to slowly rise and come above the wire to be mounted. Use the drone's camera to observe the position of the warning light and the wire. When the wire is inside the opening of the mounting device, control the drone to descend. When the wire enters the specific mounting position, it will block the beam of the sensor, which means that the sensor signal has been received.

[0071] In step 2, the servo motor 7 releases the two outriggers of the warning light sequentially according to the time order. Specifically:

[0072] Step 21: Control the short-side servo motor to release, and the short-side warning light support leg 9-1 clamps the power line conductor;

[0073] Step 22: After the set delay time, control the long-side servo to release, and the long-side spring support clamps the wire;

[0074] Optionally, the set waiting time can be less than 0.1 seconds; preferably, it can be set to 50 milliseconds. After 50 milliseconds, the CPU sends a servo control signal. At this time, the warning light is fully attached to the wire. Then, control the drone to slowly ascend and return. This completes one warning light attachment operation.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
