Description

Technical Field

[0001] This invention relates to an automatic disassembly and assembly device for warning lights, and more particularly to an automatic disassembly and assembly device for drones used on overhead power lines. Background Technology

[0002] In recent years, both military and civilian drones and other aerial technologies have developed rapidly. However, flight safety cannot be ignored. High-voltage lines are difficult to observe and are easily missed by sensors. They are obstacles that have a significant impact on the safety of drones during flight. To solve this problem, the most common method is to set up warning lights to alert the pilot and encourage them to avoid the lines.

[0003] Warning lights are inconvenient to install during power line installation, and many high-voltage lines are already in place, making it almost impossible for manual installation of warning lights onto them. Even if installation were possible, it would involve significant risks associated with working at height. Furthermore, due to their high-altitude location, warning lights are susceptible to environmental influences, resulting in a shorter lifespan. If damage requires disassembly and repair, manual removal of the warning lights from the high-voltage lines is also difficult. Therefore, this application designs an automatic drone-based installation and removal device for overhead power lines, which can work with drones to automatically and securely install and remove warning lights. Summary of the Invention

[0018] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0020] This embodiment mainly describes the title of an automatic unmanned aerial vehicle (UAV) assembly / disassembly device for overhead power lines, as detailed below: like Figure 1-9 As shown, an automatic drone disassembly and assembly device for overhead power lines includes, The frame is equipped with a warning component and has at least one insertion hole 101 on its bottom side; The gripper is mounted on the frame and includes two hinged gripper bodies with protrusions on the inner sides of the two gripper bodies; A reset element, which is disposed between two claws to apply a clamping force to the two claws; Disassembly and assembly components, including: A U-shaped plate, one end of which is hinged to one of the claws, has an abutment surface at the end of the plate on the lower side of its opening, and both claws have notches with the U-shaped plate located at the notches. The hook body is fixed to another claw body and includes at least two claw bodies. The upper side of the hook body has a release port located below the protrusion, and the bottom side of the protrusion is provided with a guide slope. The release rod is located inside the hook body; The lifting frame is fixed to the drone. It has a rod in the middle that mates with the insertion hole 101. It has two uprights on both sides. The top of the uprights has a support platform for lifting the rod. The top of the support platform has a V-shaped notch. The lowest point of the V-shaped notch is offset from the rod. The rod and the insertion hole 101 are preferably triangular. In addition, there is a set of uprights and the structure on them on the left and right sides. Initially, the abutment surface on the U-shaped plate abuts against the release rod, spreading the two claws apart. When mounting is required, the drone raises the frame, the U-shaped plate is pressed down by the wiring, the abutment surface separates from the release rod, the U-shaped plate swings down and releases its spread, the two claws are pulled by the tension spring and clamped, and at this time the movable end of the U-shaped plate extends out from the notch of one claw. When disassembly is required, the drone raises and pushes the release rod up through the support platform, and drives the two claws to unfold when the release rod abuts against one claw. The release rod continues to move upward and disengages from the release port under the action of the guide slope. After the upward push ends, it falls to above the hinge position in the middle of the two claws. The U-shaped plate swings down until the upper part of its opening abuts against the release rod and the release rod is at the root of the hook. The lower part of the opening of the U-shaped plate abuts against the bottom edge of the notch of one claw and spreads the two claws apart under the action of gravity. During installation, a stepped rod is inserted into the insertion hole 101 on the drone. After the drone flies and aligns the opening of the gripper with the line, it continues to rise. The line presses down on the U-shaped plate, and the two grippers lock. After locking, the drone descends, allowing the rod to disengage from the insertion hole 101, and the drone flies to the ground on its own. During disassembly, a release rod is pushed off the drone using a lifting platform. The release rod disengages from the release port, and the two grippers open under the gravity of the U-shaped plate. The drone descends, transporting the entire device to the ground.

[0021] Preferably, one side of the claw body has an unlocking groove on the notch sidewall, and the lower sidewall of the U-shaped plate opening has several sloping steps with gradually increasing thickness from top to bottom. When the U-shaped plate extends from the notch, the sloping steps hook onto the edge of the claw body and lock it in place. When the U-shaped plate swings up until the sloping steps are located at the unlocking groove, the U-shaped plate can be pulled back from the notch. This design is mainly used for clamping. When clamping, the U-shaped plate swings down, and the sloping surfaces of the sloping steps slide on the upper contour of the unlocking groove and lock onto the edge of the claw body below the unlocking groove step by step. When unlocking, when the U-shaped plate swings up to abut against the top of the notch, the sloping steps are located in the unlocking groove and can be pulled back from the unlocking groove. This structure adds an extra layer of anti-disengagement during clamping, avoiding the risk of the entire device falling due to fatigue or damage to the tension springs, etc.

[0022] Preferably, the upper side of the insertion rod has a stepped structure with a tapered guide structure at its top. A support spring is fitted at the stepped structure. When the insertion rod is inserted into the insertion hole 101, the support spring supports the entire device and keeps the support platform and the release rod separated. During disassembly, the drone rises, further compressing the support spring, causing the support platform to contact the release rod and push it upwards to release the rod. In this design, the tapered guide structure allows for a certain error during insertion and also provides guidance. The step serves as a support spring, which in turn supports the entire device. Finally, by setting the support spring, during installation, the support spring prevents the release rod from being squeezed in the air, thus avoiding premature release of the lock between the U-shaped plate and the release rod. When pushing the rod upwards to release it, the circuit will apply a certain pressure to the protrusion, which can be achieved by the drone continuing to rise, increasing the pressure and further compressing the support spring. In addition, after insertion, the insertion rod and the insertion hole 101 should form a sliding structure with a small clearance to avoid shaking.

[0023] Preferably, the upright frame is provided with a mounting groove, and the support platform is slidably disposed within the mounting groove. Two spring springs are installed within the mounting groove, with one end of each spring fixedly connected to the end of the mounting groove and the other end fixedly connected to the support platform. In this design, the support platform is configured as a sliding structure. During the upward release of the rod, the rod will move towards the center as it moves upwards. Therefore, a sliding structure is provided to accommodate this movement. However, it must be used in conjunction with two spring springs to ensure that the inclined surface of the support platform exerts an upward force on the rod. When the rod moves from the release opening towards the center under the action of the guide inclined surface and detaches from the rear hook, the two spring springs apply a restoring force to the support platform, pushing the rod to the root of the hook. At the root, the rod does not return to its original position, so an elastic force is applied to assist the U-shaped frame in opening the two claws.

[0024] Preferably, when the two claws are clamped, the two protrusions abut against each other, and a cross structure is formed on the upper side of the two claws. A ring structure is formed between the cross structure and the two protrusions, and the claws are hung on the line.

[0025] Preferably, the top of the two claws is provided with a first arched part and a second arched part that are staggered front to back. The first arched part and the second arched part have an arched structure facing each other. When the two claws are clamped, the first arched part and the second arched part form at least two intersections on both sides of the apex of the arched structure.

[0026] Preferably, the reset element is a torsion spring, which is located at the hinge position of the two claws; or the reset element is a tension spring, which is connected to the two claws to apply tension. In this solution, the reset element is used to provide clamping force during installation. After clamping, the U-shaped plate will be inserted into the notch of one claw and locked, thereby achieving clamping. At this time, the gravity of the U-shaped plate has a small promoting effect on the clamping of the two claws. Since it is inserted into the notch, its gravity will not cause the claws to open.

[0027] Preferably, the abutment surface is an arc surface that fits against the side wall of the release bar, and a spherical protrusion is provided at the abutment surface. The spherical protrusion cooperates with the abutment surface to make the U-shaped plate lock onto the release bar. In this solution, the spherical protrusion is used to abut against the upper side wall of the release bar to form a limit and prevent the release bar from detaching. This spherical protrusion can be set as a spring pin.

[0028] Preferably, the warning assembly includes a warning light mounted on the frame and a solar panel, with the solar panel powering the warning light.

[0029] Preferably, the two claws are hinged to the frame and have extensions extending to both sides of the frame. The extensions have limiting abutment slopes, which limit the rotation angle of the claws.

[0030] It should be noted that the U-shaped plate is a counterweight plate, with the upper part of its opening longer than the lower part, and the end of its opening side can be made into a high-density structure to promote clamping and opening. In addition, it and the frame are made of insulating materials. The release rod 50 is a hollow round tube, and there are two hooks 604 distributed on both sides of the notch 602. The hooks 604 are provided with arc grooves and the abutting surface 702 is an arc surface. Both the arc groove and the arc surface are in contact with the side wall of the release rod 50. In this embodiment, the U-shaped plate 70 is used to assist in unlocking. During the opening process, the opening force is similar to a sine curve from vertical to horizontal, that is, it increases first and then decreases. In this embodiment, only the segment that increases from small to large is used. As can be seen from the attached figure, when unlocking, from the near horizontal swing to the tilted state, the opening force gradually increases to overcome the tension of the tension spring and achieve unlocking. The tension spring is not shown in the attached figure. The tension spring is located on the upper side of the hinge position of the two claws.

[0031] It should be noted that the release rod 50 is a hollow cylindrical tube, and there are two hooks 604 distributed on both sides of the notch 602. The hooks 604 are provided with arc grooves and the abutment surface 702 is an arc surface. Both the arc grooves and the arc surface are in contact with the side wall of the release rod 50. The U-shaped plate 7070 is used to assist in unlocking in this embodiment. During the opening process, the opening force is similar to a sine curve from vertical to horizontal, that is, it first increases and then decreases. In this embodiment, only the segment that increases from small to large is used. As can be seen from the attached figure, when unlocking, from the near horizontal swing to the tilted state, the opening force gradually increases, thereby overcoming the tension of the tension spring to achieve unlocking. The tension spring is not shown in the attached figure. The tension spring is located on the upper side of the hinge position of the two grippers.

[0032] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.
