High-altitude intelligent warning light

Abstract

This invention discloses a high-altitude intelligent warning light, including a mounting and dismounting structure and a light body. The mounting and dismounting structure includes a gripper assembly formed by hinged first and second grippers. A release mechanism is hinged to the first gripper, and its locking groove cooperates with a release rod on the second gripper to open the gripper. A first tension spring connects a sliding rod and the release rod. The release mechanism is annular, with a first inclined surface, a second inclined surface, and multiple locking grooves on the upper crossbar, and a protrusion and locking groove on the lower crossbar. The second gripper has a retaining ring, and the first gripper has a zigzag sliding groove. A second tension spring is provided between the release extension and the sliding rod. During operation, it has three states: open, clamped, and unlocked. When clamped, the release rod engages with the locking groove, and the limiting protrusion engages with the V-shaped groove, achieving triple locking in conjunction with the tension spring. When unlocked, pushing the release mechanism causes the sliding rod to slide along the upper section of the sliding groove to release force. The release rod slides to the retaining ring's force-relieving position, and the gripper automatically opens. This invention can be remotely installed and disassembled via drone, with reliable locking and convenient maintenance.

Description

Technical Field

[0001] This invention relates to high-altitude warning lights, and more particularly to intelligent high-altitude warning lights. Background Technology

[0002] Warning lights are typically installed after high-voltage cables are laid to alert nearby personnel or equipment such as aircraft to their presence, effectively preventing external damage. However, current warning lights, once installed on cables, are difficult to remove, especially for overhead cables. These lights are usually installed before the cables are laid overhead, but the considerable height makes them inaccessible to workers. Therefore, disassembling, maintaining, or replacing damaged warning lights during subsequent use is quite troublesome.

[0003] Several improvements have been made in the existing technology. For example, Chinese invention patent application CN119879143A discloses a multifunctional solar-powered warning light. Its two grippers are spread apart by a central plate, and the plate is released by pressing it down with an electric wire after being lifted by a drone. After release, the two grippers are locked back together by the tension of a spring. However, this patented structure is prone to loosening because the clamping force is only achieved through the tension spring. To address this, our company has added a locking mechanism by setting a locking groove. However, since the high-voltage line is located at a high altitude, drone-assisted installation is required. If the warning light is damaged after installation, it also needs to be removed by drone. The aforementioned improved structure with two locking mechanisms cannot be disassembled by drone, leading to difficulties in the maintenance of the warning light.

[0004] Therefore, there is an urgent need to design a high-altitude warning light that has both a multi-locking structure and can be installed and removed by drones. Summary of the Invention

[0005] In response to the problems mentioned in the background art, the present invention provides a high-altitude intelligent warning light.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: The high-altitude intelligent warning light includes a loading and unloading structure and a light body installed on the loading and unloading structure. The loading and unloading structure includes: A gripper assembly, comprising a first gripper and a second gripper hinged at the bottom; The release mechanism is hinged to the first gripper and its movable end extends to the second gripper, and it is provided with a locking groove. The release lever is located at the second gripper, and the clamping groove engages with the release lever to clamp the two grippers apart; The first tension spring has one end engaged with the first gripper and the other end connected to the release rod; The release mechanism is a ring structure with an upper crossbar and a lower crossbar. The bottom of the upper crossbar has a first inclined surface and a second inclined surface extending downward and then upward from right to left. The second inclined surface has at least two locking grooves for engaging with the release lever. The top of the lower crossbar has a protrusion. The locking groove is located on the right side wall of the protrusion. The top surface of the protrusion has a third inclined surface and a fourth inclined surface extending downward and then upward from right to left. The third inclined surface is parallel to the first inclined surface and the distance between them is greater than the maximum width of the release lever. The second gripper is provided with a retaining ring, which forms a ring structure with the second gripper, and the release rod is located inside the ring structure. The first gripper is provided with a zigzag-shaped groove. The middle of the groove is convex to the left and the groove includes an upper section and a lower section. The slope of the upper section is greater than that of the lower section and the top end of the upper section is located to the right of the bottom end of the lower section. A sliding rod is provided in the groove and one end of the first tension spring is fixed to the sliding rod. The bottom left side of the release mechanism is hinged to the first gripper, and its top left side is provided with an extension that extends to the left. A second tension spring is provided between the extension and the slide bar. Its working state includes the following: In the open state, the first and second grippers are open, and the release mechanism uses the locking groove to push the two grippers open and maintain the open state against the release lever; In the clamped state, the release lever is released from the pressure of the wire, and the first and second jaws close together under the action of the first tension spring to clamp the wire. The release lever slides along the first inclined surface into the locking groove to form a limit. In this state, the slide rod is located at the bottom end of the lower section of the slide groove. In the unlocked state, the trip continues to be pressured by the wire and flips downward. The extension pulls up the second tension spring and causes the slide rod to slide into the end of the upper section of the slide groove to relieve the force on the first tension spring. The first and second grippers then release.

[0007] Preferably, both the first and second grippers are provided with avoidance holes that allow for release rotation. The sidewall of the avoidance hole on the second gripper is provided with a first groove and a second groove spaced apart, and the release mechanism is provided with a limiting boss that cooperates with the two grooves. The limiting boss gradually thickens from right to left and forms a guide slope on the front side. In the open state, the limiting boss is located in the first groove. In the clamped state, the limiting boss is located at the gap between the two grooves and hooks into the gap. In the unlocked state, the limiting boss is located at the second groove.

[0008] Preferably, both the first and second grippers have arc-shaped segments, and the two arc-shaped segments form a clamping space with a large width in the middle and a small width on the top and bottom sides. The maximum width of the clamping space is greater than the maximum outer diameter of the wire, so that the wire is located above the maximum width of the clamping space when clamped.

[0009] Preferably, a V-shaped groove is provided at the gap between the two grooves, and in the clamped state, the left end of the limiting boss is stuck in the V-shaped groove.

[0010] Preferably, the slide groove extends through to form a sliding hole, the slide rod extends through the sliding hole, and the first tension spring has two symmetrical springs that are connected to the front and rear ends of the slide rod respectively.

[0011] Preferably, the retaining ring includes a first concave arc segment and a second concave arc segment, with a smooth transition between the first and second arc segments. The first arc segment is located on the upper side, and the leftmost side of the inner wall of the first arc segment is located to the right of the leftmost side of the inner wall of the second arc segment. In the unlocked state, the release lever slides from the first arc segment to the second arc segment, so that the sliding lever and the release lever reach the minimum distance.

[0012] Preferably, the lamp body includes a lamp frame, a solar panel mounted on the lamp frame, and a warning light. The solar panel charges the built-in power supply of the warning light, and the mounting structure is fixed to the lamp frame.

[0013] Preferably, the bottom of the lamp holder is provided with at least one irregularly shaped insertion hole for inserting lifting tools.

[0014] Compared with the prior art, the present invention has the following advantages: The high-altitude intelligent warning light of the present invention achieves reliable switching between three states—open, clamped, and unlocked—through the coordinated operation of the release mechanism, the release rod, the first tension spring, and the second tension spring. The first inclined surface, the second inclined surface, and multiple locking grooves on the release mechanism, together with the retaining ring on the second gripper and the zigzag groove on the first gripper, form a triple locking structure during clamping: the release rod engages with the locking groove, the limiting boss engages with the V-shaped groove, and the first tension spring provides continuous tension. This effectively resists strong winds and line vibrations. Under harsh working conditions such as high-altitude operation, the warning light is ensured to never come loose. At the same time, during unlocking, the crossbar is released by pushing it off from the ground via a drone. The second tension spring drives the slide rod to move along the upper section of the slide groove to change the direction of the tension of the first tension spring. With the help of the retaining ring, the release rod slides to the unloading position, which can quickly release all the locks and make the grippers open automatically. This enables remote and convenient disassembly in high-altitude environments, which greatly reduces the difficulty and cost of operation and maintenance. In addition, the arc-shaped section of the gripper forms a clamping space that is wide in the middle and narrow at the top and bottom, so that the cable is located above the maximum width when clamped, which further improves the clamping stability and safety.

[0017] Detailed Implementation 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.

[0018] 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

[0019] This embodiment mainly describes the title of the high-altitude intelligent warning light, as follows: Example

[0020] Overall structure like Figure 1-5 As shown, the high-altitude intelligent warning light provided by the present invention includes a mounting structure and a lamp body 14 mounted on the mounting structure. The lamp body 14 includes a lamp holder 141, a solar panel 142 mounted on the lamp holder 141, and a warning light 143. The solar panel 142 charges the built-in power supply of the warning light 143. The mounting structure is fixed to the lamp holder 141.

[0021] The loading and unloading structure includes a gripper assembly, a release lever 3, a release rod 4, a first tension spring 6, and a second tension spring 7.

[0022] The gripper assembly includes a first gripper 1 and a second gripper 2 hinged together at their bottom via a hinge shaft 213. The two grippers can rotate relative to each other around the hinge shaft 213 to open or close. Both the first gripper 1 and the second gripper 2 have arc-shaped segments 214. The two arc-shaped segments 214 form a clamping space with a wider middle section and narrower upper and lower sides. The maximum width of this clamping space is greater than the maximum outer diameter of the cable 620, so that the cable is positioned above the maximum width of the clamping space when clamped, thus ensuring clamping stability.

[0023] The trip unit 3 has an overall ring structure, including an upper horizontal bar 311, a lower horizontal bar 312, a left vertical bar, and a right vertical bar. The bottom left side of the trip unit 3 (i.e., the lower end of the left vertical bar) is hinged to the first gripper 1 by a pin, and the trip unit 3 can rotate relative to the first gripper 1 around the pin. The top left side of the trip unit 3 is provided with an extension 31 extending to the left.

[0024] The bottom of the upper crossbar 311 has a first inclined surface 32 and a second inclined surface 33 extending downwards and then upwards from right to left. The second inclined surface 33 has at least two locking grooves 34 for engaging with the release rod 4. In this embodiment, three locking grooves 34 are preferably provided to accommodate cables of different diameters.

[0025] The lower crossbar 312 has a protrusion 35 at its top, and a clamping groove 36 on the right side wall of the protrusion 35. The top surface of the protrusion 35 has a third inclined surface 37 and a fourth inclined surface 38 extending downward and then upward from right to left. The third inclined surface 37 and the first inclined surface 32 are parallel to each other, and the distance between them is greater than the maximum width of the release rod 4 to ensure that the release rod 4 can pass smoothly.

[0026] The release lever 4 is located at the second gripper 2, and shock-absorbing balls are provided at both ends of the release lever 4. Specifically, a retaining ring 9 is provided on the second gripper 2, and the retaining ring 9 and the second gripper 2 form an annular structure. The release lever 4 passes through the annular structure and can slide along the annular structure. The retaining ring 9 includes a left-concave first arc segment 91 and a left-concave second arc segment 92. The first arc segment 91 and the second arc segment 92 are smoothly transitioned, and the first arc segment 91 is located on the upper side. The leftmost side of the inner wall of the first arc segment 91 is located to the right of the leftmost side of the inner wall of the second arc segment 92, so that when the release lever 4 jumps from the first arc segment 91 to the second arc segment 92 during disassembly, the right side of the first tension spring 6 is also unloaded.

[0027] The first gripper 1 has a zigzag-shaped groove 8, with the middle of the groove 8 protruding to the left. It includes an upper section 81 and a lower section 82, with the slope of the upper section 81 greater than that of the lower section 82, and the top end of the upper section 81 located to the right of the bottom end of the lower section 82. A sliding rod 5 is provided within the groove 8. One end of a first tension spring 6 is fixed to the sliding rod 5, and the other end is connected to a release rod 4. Preferably, the groove 8 extends through to form a sliding hole, through which the sliding rod 5 passes. Two symmetrical first tension springs 6 are provided, connected to the front and rear ends of the sliding rod 5 respectively, to ensure balanced force distribution.

[0028] The second tension spring 7 is disposed between the extension 31 of the release 3 and the slide bar 5, with one end connected to the extension 31 and the other end connected to the slide bar 5.

[0029] Both the first gripper 1 and the second gripper 2 are provided with avoidance holes 13 for the release buckle 3 to pass through. The sidewall of the avoidance hole 13 on the second gripper 2 is provided with a first groove 11 and a second groove 12 spaced apart, and the release buckle 3 is provided with a corresponding limiting boss 15 that cooperates with the two. The limiting boss 15 gradually thickens from right to left and forms a guide slope on its front side to facilitate sliding into or out of the groove. A V-shaped groove 133 is also provided in the gap between the first groove 11 and the second groove 12, and the sidewall of the gap is provided with a slope from the inside to the outside. The V-shaped groove 133 extends in the front-back direction and is used to clamp and limit the limiting boss 15 in the clamped state.

[0030] The bottom of the lamp holder 141 is provided with at least one irregularly shaped insertion hole 144 (a triangular hole in this embodiment) for inserting the drone top rod to realize the remote pushing operation of the release 3.

[0031] The high-altitude intelligent warning light of the present invention has three working states: open state, clamped state, and unlocked state. The switching process is described in detail below with reference to the accompanying drawings.

[0032] 1. Open position (before installation or after disassembly) In the open state, the first gripper 1 and the second gripper 2 are in the open position. At this time, the release lever 3 abuts against the release rod 4 through its abutment groove 36, and the two grippers are opened and maintained by the supporting action of the release lever 4 on the abutment groove 36. At the same time, the limiting boss 15 is engaged in the first groove 11, and the release lever 4 is located in the first arc segment 91 of the retaining ring 9. The entire mechanism is in a stable open posture, which facilitates the placement of the cable between the two grippers.

[0033] 2. Clamped position (installed in place) When the warning light needs to be installed on the cable, it is first positioned in the open state and lifted by a drone to the height of the cable, allowing the cable to enter the clamping space between the two grippers. Then, the cable presses downwards against the upper crossbar 311 of the trip release 3 (specifically, the area of ​​the second inclined surface 33). The trip release 3, under downward pressure, rotates clockwise around its hinge point (pin), and its clamping groove 36 gradually disengages from the release lever 4. At this point, the tension of the first tension spring 6 begins to act, pulling the first gripper 1 and the second gripper 2 closer together, ultimately clamping the cable.

[0034] During this process, the release lever 4 passes through the gap between the third inclined surface 37 and the first inclined surface 32 of the release lever 3, slides upward along the first inclined surface 32, and finally engages in the locking groove 34 on the second inclined surface 33, forming the first locking. At the same time, the limiting boss 15 slides out from the first groove 11 and engages in the V-shaped groove 133 at the gap between the first groove 11 and the second groove 12, forming the second locking. At this time, the slide lever 5 is located at the bottom end of the lower section 82 of the slide groove 8, and the first tension spring 6 is in the maximum tension state, continuously providing clamping force to the gripper, forming the third locking. The release lever 4 is located at the junction of the first arc segment 91 and the second arc segment 92 of the retaining ring 9.

[0035] The triple locking mechanism, achieved through the engagement of the locking groove 34 with the release rod 4, the engagement of the V-groove 133 with the limiting boss 15, and the continuous tension of the first tension spring 6, ensures that the warning light will never come loose in harsh environments such as strong winds and line vibrations.

[0036] 3. Unlocked state (during disassembly) When a warning light is damaged or needs replacement, the operator uses a drone to insert its push rod 611 into the irregularly shaped insertion hole 144 at the bottom of the light holder 141, and pushes the lower crossbar 312 of the release 3 upward. The release 3, under upward pressure, rotates further clockwise, and its extension 31 pulls the second tension spring 7 upward. The second tension spring 7 then pulls the slide rod 5 along the slide groove 8. Because the upper section 81 of the slide groove 8 has a large slope and its top is located on the right side, the slide rod 5 is pulled from the bottom of the lower section 82 into the top end of the upper section 81. During this process, the direction of the tension of the first tension spring 6 changes from the original closing force to a tendency towards a separating force, thus unloading the first tension spring 6, and the two grippers lose their closing power.

[0037] Simultaneously, the release lever 4 disengages from the locking groove 34 and slides along the retaining ring 9 from the first arc segment 91 to the second arc segment 92 (the second arc segment 92 is further to the left, minimizing the horizontal distance between the sliding rod 5 and the release lever 4), further releasing the tension of the first tension spring 6. The limiting boss 15 also disengages from the V-groove 133 and slides into the second groove 12. At this point, all locking structures are released, and the first clamp 1 and the second clamp 2 automatically open under the support of the release lever 3 and gravity, allowing the warning light to smoothly detach from the cable, completing the disassembly.

[0038] In this embodiment, there are two locking grooves 34. The V-shaped groove 133 can also be replaced with an arc-shaped transition groove, as long as it can lock the limiting boss 15 and keep it in that position without the action of other external forces. The irregularly shaped insertion hole 144 can be a square or cross-shaped hole in addition to a triangular hole, as long as it can form an anti-rotation fit with the top rod of the drone. In addition, an elastic pad 160 (such as silicone or rubber) can be added to the inner wall of the arc-shaped section 214 of the first gripper 1 and the second gripper 2 to increase friction and protect the cable insulation layer. All of the above substitution methods are within the protection scope of this invention.

[0039] Additionally, it should be noted that when in the open state, the release lever 4 is located within the first arc segment 91, and the slide lever 5 is located at the rightmost position of the lower section 82 of the slide groove 8; when unlocking, the release lever 4 switches to the second arc segment 92, and the slide lever 5 switches to the rightmost position of the upper section 81 of the slide groove 8. The slide lever 5 and the release lever 4 move closer to each other to relieve the force on the first tension spring 6.

[0040] 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.
