Technical Field

[0001] This invention relates to the field of warning signs for power facilities, and in particular to a high-altitude cable warning device. Background Technology

[0002] In power systems, warning signs are commonly used on power facilities and equipment such as power plants, substations, and transmission and distribution lines to serve as safety warnings. Most existing warning signs use a locking mechanism that secures them to the cable. During installation, a linker is used to prop up the sign and suspend it from the suspended cable.

[0003] However, existing technologies have the following drawbacks: First, workers face the risk of electric shock when using links to install warning signs; second, links can typically only be used for installation, not disassembly, leaving some equipment requiring maintenance unable to be removed. Therefore, existing technologies typically require prioritizing power disconnection during installation and disassembly, and workers may need to climb to heights, posing both safety hazards and low efficiency.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] This invention provides a high-altitude cable warning device 10, aiming to solve the safety and convenience problems of erecting warning signs in the prior art. For example... Figure 1 As shown, the high-altitude cable warning device 10 includes a warning sign device 100 and a drone 200. The drone 200 is used to carry the warning sign device 100 and to suspend or detach the warning sign device 100 from the overhead cable 20.

[0034] Among them, such as Figure 2 As shown, the warning sign device 100 includes: a sign body 110, a sign frame 120, a base frame 130, a sway seat 140, and a hook member 150. The sign body 110 is mounted on the sign frame 120, the base frame 130 is fixedly connected to the sign frame 120, the sway seat 140 is rotatably mounted on the base frame 130, and the hook member 150 is rotatably mounted on the sway seat 140 via a pivot 151 (e.g., ...). Figure 3 As shown in the figure, a stabilizing and resetting elastic element 160 is provided between the barb 150 and the sway seat 140. Preferably, the stabilizing and resetting elastic element 160 is a tension spring structure, and the stabilizing and resetting elastic element 160 always provides tension to the barb 150.

[0035] like Figure 3 As shown, the sway seat 140 is provided with a pointed cone 141, and a guide slope 142 is formed on the pointed cone 141. A hook jaw 152 is formed between the barb 150 and the pointed cone 141. When suspended, the hook jaw 152 is closed, and the cable 20 passes through the hook jaw 152, so that the warning sign device 100 will not easily detach from the cable 20; when detached, the hook jaw 152 opens, and the cable 20 moves away from the hook jaw 152.

[0036] It is worth noting that in this invention, the warning sign device 100 is capable of autonomous deformation. Autonomous deformation of the warning sign device 100 means that the hook grip 152 can actively switch between a "closed state" and an "open state," that is, the hook grip 152 can automatically complete the "hooking" and "unhooking" operations at an "appropriate time." This makes the cooperation between the warning sign device 100 and the cable 20 more stable and also makes operation more convenient for workers. This "appropriate time" refers to a moment when a pre-set condition is met, at which point the warning sign device 100 will deform; the specific process will be described below.

[0037] The display board 110 is printed with warning statements or signs to remind pedestrians or vehicles passing by to pay attention to the overhead cables 20.

[0038] In this embodiment, as Figure 4 As shown, the drone 200 includes: a drone body 210, a remote controller (not shown), and an auxiliary mounting bracket 220. The remote controller is wirelessly connected to the drone body 210. The auxiliary mounting bracket 220 is bolted to the drone body 210, and the warning sign device 100 is placed on the auxiliary mounting bracket 220. Preferably, the auxiliary mounting bracket 220 has a rectangular sleeve 221 for accommodating the display body 110 of the warning sign device 100, and the rectangular sleeve 221 has an integrally formed flared opening 222 for facilitating the insertion of the display body 110 into the rectangular sleeve 221.

[0039] The main working principle of the high-altitude cable warning device 10 of the present invention will be explained below:

[0040] Before hanging, staff placed the warning sign device 100 onto the auxiliary fixing frame 220, and inserted the display sign body 110 into the rectangular sleeve 221, so that the warning sign device 100 could remain "standing"; at the same time, staff tilted the sway seat 140 to the left (e.g., Figure 3 As shown), at this time, the barb 150 is pulled to the right by the stabilizing and resetting elastic element 160 (as shown). Figure 3 As shown, the barb 150 and the pointed cone 141 are far apart, and the hook jaw 152 is in the open state. This facilitates the subsequent entry of the cable 20 into the hook jaw 152;

[0041] During suspension, the operator uses a remote control to fly the drone 210 and its warning sign device 100 close to the overhead cable 20. Because the hook's grip 152 is open, the drone 210, carrying the barbed hook 150, can approach the cable 20 and hook it (e.g., ...). Figure 5 (As shown). Subsequently, the drone body 210 moves downward, the warning sign device 100 separates from the auxiliary fixing frame 220, and the warning sign device 100 is suspended from the cable 20 by the barb 150. At this time, the overall weight of the warning sign device 100 is borne by the barb 150. Under the action of gravity, the deflector 140 will deflect around the pivot 151 (this deflection process will overcome the tension of the stabilizing and resetting elastic element 160). After deflection, the pointed cone 141 of the deflector 140 approaches the barb 150 and blocks the opening of the hook jaw 152, that is, the hook jaw 152 changes to a closed state (as shown). Figure 6 (As shown), this allows the warning sign device 100 to remain suspended on the cable 20;

[0042] When disassembling and detaching, the operator uses a remote control to maneuver the drone body 210 upwards, causing the warning sign device 100 to re-engage with the auxiliary mounting bracket 220. As the drone body 210 lifts upwards, the weight of the warning sign device 100 is entirely borne by the drone body 210, and the warning sign device 100 is moved upwards by the drone body 210. Figure 7 As shown, during the upward movement, the cable 20 will fall to the bottom of the hook jaw 152 and slide down the guide slope 142 of the cone portion 141 towards the barb 150, thereby pushing the barb 150 to deflect away from the cone portion 141 (during which the elastic force of the stabilizing and resetting elastic member 160 needs to be overcome). At this time, the hook jaw 152 changes to the open state, and the warning sign device 100 can be moved down again to allow the cable 20 to detach from the hook jaw 152.

[0043] As can be seen, this invention utilizes a drone 200 to suspend the warning sign device 100 onto the cable 20. This avoids the need for climbing to heights required by traditional suspension methods and eliminates the risk of electric shock, ensuring the safety of personnel. Simultaneously, the warning sign device 100 can autonomously deform, automatically completing the "hooking" and "unhooking" operations at the "appropriate time." When the hook 150 catches the cable 20, the warning sign device 100 separates from the auxiliary fixing frame 220, and under gravity, it autonomously deforms, with the hook's jaw 152 switching to a "closed state," thus achieving the "hooking" operation. When the warning sign device 100 is lifted upwards, the cable 20 will press the hook 150 along the guide slope 142, causing it to deflect, and the hook's jaw 152 switching to an "open state," thus achieving the "unhooking" operation. This autonomous deformation not only prevents the warning sign device 100 from falling off but also makes operation more convenient for personnel, improving work efficiency.

[0044] To further improve the stability of the suspension, the present invention has made further improvements to the warning sign device 100. Specifically, as follows: Figure 8 As shown, the barb 150 has a shaped groove 153 and a movable rod 154 that slides within the shaped groove 153. The sway seat 140 has a fixed rod 143, and the stabilizing and resetting elastic member 160 connects the movable rod 154 and the fixed rod 143. Furthermore, the shaped groove 153 includes a limiting section 1531 and a resetting section 1532, with an angle formed between the central axis of the limiting section 1531 and the central axis of the resetting section 1532. When suspended, the movable rod 154 is within the limiting section 1531; when disengaged, the movable rod 154 is within the resetting section 1532.

[0045] Preferably, the angle between the central axis of the limiting segment 1531 and the central axis of the reset segment 1532 is an obtuse angle. When suspended, the reset segment 1532 of the irregular groove 153 is on a horizontal line, and the limiting segment 1531 of the irregular groove 153 is inclined downward relative to the reset segment 1532 (e.g., Figure 8 (As shown).

[0046] Next, the design principle of the irregular groove 153 that can improve suspension stability will be explained:

[0047] It should be noted in advance that, for the convenience of subsequent explanation, a virtual straight line 101 is provided between the fixing rod 143 and the irregular groove 153, and when the warning sign device 100 is suspended, the direction of the virtual straight line 101 is the direction of gravity of the warning sign device 100 (i.e. the direction of the plumb bob).

[0048] When suspended, the warning sign device 100 deforms autonomously, the hook grip 152 changes to a closed state, and the movable rod 154 slides into the limiting section 1531 (as shown). Figure 8 (As shown). At this time, the movable rod 154 is to the left of the aforementioned virtual straight line 101. The tension provided by the stabilizing and resetting elastic element 160 will cause the movable rod 154 to have a component force that pushes the hook 150 to the left, thereby causing the hook 150 to tend to deflect to the left. This tendency keeps the hook jaw 152 stably closed and the warning sign device 100 stably suspended.

[0049] When detachment is required, the warning sign device 100 is lifted upwards, and the cable 20 presses against the hook 150 and the movable rod 154 along the guide slope 142, thereby overcoming the tension of the stabilizing and resetting elastic element 160, causing the movable rod 154 to slide to the reset section 1532 of the irregular groove 153. At this time, the movable rod 154 is on the right side of the aforementioned virtual straight line 101, and the hook 150 deflects rapidly under the combined action of the push of the cable 20 and the tension of the stabilizing and resetting elastic element 160, and the hook jaw 152 switches to the "open state", thereby realizing the "unhooking" operation, and the warning sign device 100 separates from the cable 20.

[0050] It should be emphasized that after the irregular groove 153 is installed, the "unhooking" operation of the warning sign device 100 requires the following conditions to be met simultaneously:

[0051] First, the warning sign device 100 is completely lifted, that is, the weight of the warning sign device 100 is completely overcome.

[0052] Secondly, the warning sign device 100 needs to be moved upwards by a certain distance so that the cable 20 can press the barb 150 along the guide slope 142;

[0053] Third, the movable rod 154 overcomes the tension of the stabilizing and resetting elastic element 160 and slides to the resetting section 1532 of the irregular groove 153.

[0054] Under these three conditions, the warning sign device 100 exhibits good suspension stability. Even if strong winds cause the device to sway, the moving rod 154 remains stably within the limiting section 1531 of the irregular groove 153 because the cable 20 does not press against the hook 150 along the guide slope 142. Therefore, the hook 150 always tends to approach the pointed cone 141, which keeps the hook's jaw 152 stably closed. Thus, the stabilizing and resetting elastic element 160 contributes to the stable suspension of the warning sign device 100.

[0055] Moreover, when it is necessary to detach, after the movable rod 154 slides down to the reset section 1532 under the push of the cable 20, the barb 150 will quickly deflect, thereby changing the hook jaw 152 to the open state and maintaining it stably in the current state, avoiding the situation where the hook jaw 152 switches states randomly due to shaking.

[0056] Similarly, before suspension, the tension of the stabilizing and resetting elastic element 160 on the hook element 150 can ensure that the hook jaw 152 is stably in the "open state", thereby avoiding the hook jaw 152 from switching states at will due to shaking, so as to facilitate the operation of connecting the hook element 150 with the cable 20 before suspension.

[0057] In this embodiment, as Figure 3 As shown, the display stand 120 has extension eaves 121 on both sides. Below the extension eaves 121 are light strips and a photosensitive module (not shown). Inside the display stand 120 is a battery and a controller (not shown). The controller is electrically connected to the battery, light strips, and photosensitive module. When there is insufficient light (at night), the photosensitive module senses the dimming of the ambient light and transmits an electrical signal to the controller. Upon receiving the signal, the controller turns on the light strips, which then illuminate the display stand body 110. When there is sufficient light (during the day), the photosensitive module sends an electrical signal to the controller, which then turns off the light strips, thus achieving the function of turning on the lights at night and automatically turning them off during the day.

[0058] Preferably, a photovoltaic panel 122 is provided above the extension eaves 121 (e.g., Figure 2 As shown in the figure, the photovoltaic panel 122 is electrically connected to the battery via an inverter (not shown). In this way, when there is sufficient sunlight (during the day), the photovoltaic panel 122 can generate electricity using sunlight, thereby replenishing the battery with electrical energy for nighttime use.

[0059] In summary, the high-altitude cable warning device 10 of the present invention can achieve quick installation and convenient disassembly while meeting safety requirements, and at the same time ensure good stability after suspension, thereby improving work efficiency and safety.

[0060] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
