Description

A drone-based high-altitude power line warning light mounting device Technical Field

[0001] This invention relates to the field of power line warning light mounting technology, and in particular to a high-altitude power line warning light mounting device based on a drone. Background Technology

[0002] Existing methods for installing warning lights on power transmission and distribution lines include using insulated operating rods for shorter lines and employing live-line working methods for taller lines, which are extremely risky, cumbersome, and inefficient. Using drones to install warning lights on power transmission and distribution lines can avoid these risks, significantly improve efficiency, and eliminate the limitations imposed by the height of the power lines and terrain.

[0003] However, there are currently no dedicated drones for high-altitude suspension installation, requiring the use of conventional drones and other mounting devices to suspend and install warning lights. Furthermore, existing mounting accessories lack clamping mechanisms, causing the warning lights to easily sway or slide along power lines after installation, resulting in unstable suspension. Technical issues

[0004] How to design a drone-based high-altitude power line warning light mounting device that allows for convenient and quick mounting of warning lights onto high-altitude power lines, and prevents them from shaking or slipping after mounting, thereby achieving convenient and stable mounting operations and improving work efficiency, is a technical problem that technicians in this field need to solve. Technical solutions

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A drone-based high-altitude power line warning light mounting device includes: a fixed base, a movable mechanism, and an elastic element. The movable mechanism is rotatably mounted on the fixed base, and the elastic element connects the fixed base and the movable mechanism.

[0007] The fixed base is provided with two fork arms, and a clamping jaw is formed between the two fork arms for clamping external cables. An avoidance groove that cooperates with the movable mechanism is provided on the inner wall of the clamping jaw. The fixed base is provided with a rotating shaft and a connecting end.

[0008] The active mechanism includes a rotating body disposed on the rotating shaft, the rotating body having an irregular hole, the rotating shaft passing through the irregular hole, the irregular hole having a transverse section and a longitudinal section; the rotating body is provided with a linkage rod, an extension arm and a clamping arm, the linkage rod being connected to the elastic element, and both the extension arm and the clamping arm being able to freely pass through the clearance groove;

[0009] The movable mechanism has a waiting state and a clamping state when it is engaged with the fixed base.

[0010] In one embodiment, both fork arms are obliquely connected to the gripping jaws and have an included angle, so that a flared structure is formed between the two fork arms.

[0011] In one embodiment, the rotating body is formed by combining two trigger plates, which are linked together by the rotating shaft and the linkage rod, and the number of clearance slots is the same as the number of trigger plates.

[0012] In one embodiment, the movable mechanism includes a limiting structure disposed on the rotating body, the limiting structure abutting against or moving away from the fixed seat; when the rotating body rotates under the action of the elastic member, the limiting structure is used to limit the size of the clamping space formed between the clamping arm and the clamping jaw.

[0013] In one embodiment, the limiting structure is rod-shaped, passing through the rotating body but not through the clearance groove. When the rotating body rotates into position, the end of the limiting structure will abut against the fixed seat.

[0014] In one embodiment, the limiting structure is an elastic clamp, the limiting structure is provided with a long rod and a crossbar, the extension arm is provided with a plug hole, and the end of the long rod of the limiting structure is engaged in the plug hole; when the rotating body rotates to the position, the crossbar of the limiting structure will abut against the inner wall of the clamping jaw.

[0016] In one embodiment, a buffer pad is provided on the side of the clamping arm near the gripping jaws. When the rotating body is triggered to rotate, the clamping arm will press against the external cable through the buffer pad.

[0017] In one embodiment, the rotating body is provided with a reset gripping ring.

[0018] In one embodiment, the elastic element is a tension spring structure, with one end connected to the end of the fork arm and the other end connected to the linkage rod of the rotating body. Beneficial effects

[0028] This invention provides a drone-based high-altitude power line warning light mounting device 10, designed to conveniently and quickly mount warning lights onto high-altitude power lines using a drone, while maintaining stability after mounting. As shown in Figures 1 and 2, the mounting device 10 includes: a fixed base 100, a movable mechanism 200, and an elastic element 300. The movable mechanism 200 is rotatably mounted on the fixed base 100, and the elastic element 300 connects the fixed base 100 and the movable mechanism 200.

[0029] As shown in Figures 2 and 3, the fixed base 100 is provided with two forks 110, and a clamping jaw 101 for clamping the external cable 20 is formed between the two forks 110. An avoidance groove 120 that cooperates with the movable mechanism 200 is provided on the inner wall of the clamping jaw 101. The fixed base 100 is provided with a rotating shaft 130 and a connecting end 140, which is used to connect to an external warning light.

[0030] As shown in Figures 4 and 5, the movable mechanism 200 includes a rotating body 220 mounted on a rotating shaft 130. The rotating body 220 has a shaped hole 221 through which the rotating shaft 130 passes. The shaped hole 221 includes a transverse section 222 and a longitudinal section 223. The rotating body 220 is equipped with a linkage rod 230, an extension arm 240, and a clamping arm 250. The linkage rod 230 is connected to the elastic element 300. Both the extension arm 240 and the clamping arm 250 can freely pass through the clearance groove 120.

[0031] The movable mechanism 200 has a waiting state and a clamping state when it cooperates with the fixed base 100. When the external cable 20 enters the clamping jaws 101 and contacts the rotating body 220, the movable mechanism 200 changes from the waiting state to the clamping state. Specifically, in the waiting state, the extension arm 240 is located in the transverse section 222 of the irregular hole 221 around the rotating shaft 130, and the end of the extension arm 240 abuts against the edge of the clearance groove 120, and the elastic element 300 accumulates elastic potential energy; in the clamping state, the external cable 20 is located in the clamping jaws 101, and around the rotating shaft 130 is located in the longitudinal section 223 of the irregular hole 221, the clamping arm 250 presses against the external cable 20, and the elastic element 300 releases elastic potential energy. The specific working principle of the mounting device 10 will be explained below.

[0032] In this embodiment, as shown in FIG3, both fork arms 110 are obliquely connected to the clamping jaws 101 and have an included angle, so that a flared structure is formed between the two fork arms 110. In this way, the external cable 20 can more easily enter the clamping jaws 101 from the opening.

[0033] In this embodiment, the rotating body 220 is formed by combining two trigger plates 224 (as shown in Figure 5). The two trigger plates 224 form a whole and are linked together by rotating shaft 130 and linkage rod 230. The number of clearance slots 120 is the same as the number of trigger plates 224. Preferably, the rotating body 220 is provided with a reset gripping ring 260, which is used to facilitate the reset of the rotating body 220, that is, to change from the clamping state back to the waiting state.

[0034] Preferably, as shown in Figures 3 and 4, the elastic element 300 is a tension spring structure, with one end connected to the end of the fork arm 110 and the other end connected to the linkage rod 230 of the rotating body 220. Of course, the elastic element 300 can also be a torsion spring structure, which can also provide the power required for the rotating body 220 to change state.

[0035] The working principle of the mounting device 10 is explained below, with reference to Figures 2, 5, and 6:

[0036] Initially, the fixed base 100 is connected to the external warning light and placed on the drone. At this time, the movable mechanism 200 is in a waiting state, located around the pivot 130 in the transverse section 222 of the irregular hole 221, the extension arm 240 is in the gripping mouth 101, and the end of the extension arm 240 abuts against the edge of the clearance groove 120, and the elastic element 300 is stretched and accumulates elastic potential energy;

[0037] In use, the operator controls the drone to ascend, and the mounting device 10 gradually approaches the external cable 20 located at a high position, causing the external cable 20 to enter the clamping jaws 101. When the external cable 20 presses against the extension arm 240, the moving mechanism 200 is triggered. The specific triggering process is as follows: the external cable 20 presses against the inclined extension arm 240, causing the rotating body 220 to shift horizontally to the left. At this time, it slides around the pivot 130 to the intersection of the transverse section 222 and the longitudinal section 223. Subsequently, under the pulling force of the elastic element 300, the rotating body 220 moves downward, causing it to enter the longitudinal section 223 around the pivot 130. At the same time, the downward movement of the rotating body 220 causes the end of the extension arm 240 to no longer abut against the edge of the clearance groove 120, and the extension arm 240 falls into the range of the clearance groove 120. At this time, under the action of the elastic element 300, the rotating body 220 deflects around the pivot 130, and the extension arm 240 passes through the clearance groove 120; the clamping arm 250 enters the clamping jaw 101 and, in conjunction with the inner wall of the clamping jaw 101, clamps the external cable 20, and the movable mechanism 200 changes from the waiting state to the clamping state. Then, the operator controls the drone to descend, thus suspending the mounting device 10 and the warning light on the external cable 20;

[0038] When disassembly is required, the operator pushes the reset gripping ring 260 to cause the rotating body 220 to rotate in the opposite direction and open, the clamping arm 250 to exit the clamping jaw 101, and the external cable 20 can then be released from the clamping jaw 101; then the operator pushes the rotating body 220 upward, so that the rotating shaft 130 re-enters the transverse section 222, and the end of the extension arm 240 abuts against the edge of the clearance groove 120 again, thus resetting the mounting device 10 for the next use.

[0039] Compared to existing technologies, the mounting device 10 of this invention does not require operator intervention during mounting. The operator only needs to control the drone to ascend, bringing the mounting device 10 into contact with the external cable 20 to trigger the movable mechanism 200. This causes the movable mechanism 200 to deform autonomously to clamp the external cable 20, completing the suspension process. After suspension, the mounting device 10 exerts a clamping force on the external cable 20, resulting in significant friction between them. Therefore, after suspension, the mounting device 10 and the warning light are less likely to sway or slip relative to the external cable 20, ensuring suspension stability.

[0040] Furthermore, it should be emphasized that the mounting device 10 of the present invention has a wide range of applications and can be compatible with cables of different thicknesses. In the clamping state, a clamping space is formed between the clamping arm 250 and the clamping jaw 101. As the rotating body 220 rotates, the clamping arm 250 gradually deflects, and the clamping space will shrink accordingly until the clamping arm 250 presses against the external cable 20.

[0041] Furthermore, in practical use, it was found that at the instant the movable mechanism 200 changes to the clamping state, the clamping arm 250 suddenly presses down on the external cable 20, which can easily damage the external cable 20. Especially when the external cable 20 is thin, the rotational acceleration of the rotating body 220 is large, and the clamping force of the clamping arm 250 at the instant is strong, which can easily cause the wire core inside the external cable 20 to be bent or cut, causing irreversible damage. To this end, the present invention also provides a limiting structure 270 on the movable mechanism 200.

[0042] Specifically, this type of limiting structure 270 is provided on the rotating body 220, and it rotates together with the rotating body 220. It limits the deflection movement of the rotating body 220 by abutting against or moving away from the fixed seat 100. When the rotating body 220 rotates under the action of the elastic member 300, the limiting structure 270 is used to limit the size of the clamping space formed between the clamping arm 250 and the clamping jaw 101, thereby preventing the clamping arm 250 from excessively pressing on the external cable 20 and causing damage.

[0043] The following describes two specific embodiments to illustrate this type of limiting structure 270; Example 1:

[0044] As shown in Figures 5 and 6, the limiting structure 270 is rod-shaped. This limiting structure 270 passes through the rotating body 220 but cannot pass through the clearance groove 120. When the rotating body 220 rotates into position, the end of the limiting structure 270 will abut against the fixed seat 100.

[0045] Specifically, during use, when the external cable 20 enters the clamping jaws 101 and triggers the movable mechanism 200, the rotating body 220 deflects under the tension of the elastic element 300, causing the movable mechanism 200 to change to a clamping state. The limiting structure 270 rotates together with the rotating body 220 until it abuts against the fixed base 100. At this point, the rotating body 220 is restricted and cannot continue to rotate, and the position of the clamping arm 250 is fixed, thus preventing shearing force from being applied to the external cable 20 and protecting the external cable 20. Example 2:

[0046] As shown in Figures 7 and 8, the limiting structure 270 is an elastic clamp. The limiting structure 270 is provided with a long rod 271 and a crossbar 272. The extension arm 240 is provided with a insertion hole 241. The end of the long rod 271 of the limiting structure 270 is engaged in the insertion hole 241. When the rotating body 220 rotates to the position, the crossbar 272 of the limiting structure 270 will abut against the inner wall of the clamping jaw 101.

[0047] Specifically, during use, when the external cable 20 enters the clamping slot 101 and triggers the movable mechanism 200, the rotating body 220 deflects under the tension of the elastic element 300, causing the movable mechanism 200 to change to a clamping state. The extension arm 240 passes through the clearance groove 120 until the crossbar 272 of the limiting structure 270 abuts against the inner wall of the clamping slot 101. At this time, the length of the long bar 271 limits the deflection angle of the rotating body 220, thereby limiting the size of the clamping space, so that the clamping arm 250 will not excessively press the external cable 20 to form a shearing force, thus protecting the external cable 20.

[0048] Furthermore, there are multiple insertion holes 241, evenly arranged. During use, the operator selects the appropriate insertion hole 241 to cooperate with the limiting structure 270 based on the thickness of the external cable 20, thereby changing the deflection angle of the rotating body 220, controlling the size of the clamping space, and thus adapting to external cables 20 of different thicknesses. Alternatively, multiple limiting structures 270 with different lengths of the long rod 271 can be designed. During use, the operator selects the limiting structure 270 to change the length of the long rod 271, thereby limiting the deflection angle of the rotating body 220, controlling the size of the clamping space, and similarly adapting to external cables 20 of different thicknesses.

[0049] In other embodiments, a buffer pad (not shown) is provided on the side of the clamping arm 250 near the clamping grip 101. When the rotating body 220 is triggered to rotate, the clamping arm 250 will press against the external cable 20 through the buffer pad. This can reduce the impact force of the clamping arm 250 on the external cable 20, so that the instantaneous shearing force is not too large, and prevent damage to the external cable 20. Industrial applicability

[0050] The high-altitude power line warning light mounting device 10 based on UAV of the present invention can conveniently and quickly mount the warning light onto the external cable 20, and it is not easy to shake or slip after mounting, thereby realizing convenient and stable mounting operation, improving work efficiency and operational safety.
