The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] The present invention provides a high-altitude wire warning light mounting device 10 based on a drone, which is intended to use a drone to conveniently and quickly mount a warning light on a high-altitude wire, and to maintain stability after mounting. Figure 1 and Figure 2 As shown, the hanging device 10 includes a fixed base 100 , a movable mechanism 200 and an elastic member 300 . The movable mechanism 200 is rotatably mounted on the fixed base 100 , and the elastic member 300 connects the fixed base 100 and the movable mechanism 200 .

[0034] like Figure 2 and Figure 3 As shown, the fixing seat 100 is provided with two fork arms 110, and a clamping jaws 101 for clamping the external cable 20 is formed between the two fork arms 110. An avoidance groove 120 cooperating with the movable mechanism 200 is provided on the inner wall of the clamping jaws 101. A rotating shaft 130 and a connecting end 140 are provided on the fixing seat 100, and the connecting end 140 is used to connect to an external warning light.

[0035] like Figure 4 and Figure 5As shown, the movable mechanism 200 includes a rotating body 220 mounted on the rotating shaft 130. A special-shaped hole 221 is defined in the rotating body 220, through which the rotating shaft 130 passes. Special-shaped hole 221 includes a transverse section 222 and a longitudinal section 223. The rotating body 220 is provided with a linkage rod 230, an extension arm 240, and a clamping arm 250. The linkage rod 230 is connected to the elastic member 300, and both the extension arm 240 and the clamping arm 250 can freely pass through the avoidance groove 120.

[0036] The movable mechanism 200 has a waiting state and a clamping state when it cooperates with the fixed seat 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, when in the waiting state, the rotating shaft 130 is located in the transverse section 222 of the special-shaped hole 221, the end of the extension arm 240 is against the edge of the avoidance groove 120, and the elastic member 300 accumulates elastic potential energy; when in the clamping state, the external cable 20 is located in the clamping jaws 101, the rotating shaft 130 is located in the longitudinal section 223 of the special-shaped hole 221, the clamping arm 250 is pressed on the external cable 20, and the elastic member 300 releases elastic potential energy. The specific working principle of the hanging device 10 will be described below.

[0037] In this embodiment, if Figure 3 As shown, the two fork arms 110 are connected to the clamping jaws 101 at an angle and have an included angle, so that a bell-mouth structure is formed between the two fork arms 110. In this way, the external cable 20 is more easily inserted into the clamping jaws 101 from the opening.

[0038] In this embodiment, the rotating body 220 is composed of two triggering pieces 224 (such as Figure 5 The two trigger plates 224 are formed as a whole by rotating around the rotating shaft 130 and the linkage rod 230, and the number of the avoidance grooves 120 is the same as the number of the trigger plates 224. Preferably, a reset grip ring 260 is provided on the rotating body 220 to facilitate the reset of the rotating body 220, that is, to return the rotating body 220 from the clamping state to the waiting state.

[0039] Preferably, Figure 3 and Figure 4 As shown, the elastic member 300 is a tension spring structure, one end of the elastic member 300 is connected to the end of the fork arm 110, and the other end is connected to the linkage rod 230 of the rotating body 220. Of course, the elastic member 300 can also be a torsion spring structure, which can also provide the rotating body 220 with the power required for state changes.

[0040] The working principle of the hanging device 10 is described below. Figure 2 、 Figure 5 and Figure 6 As shown:

[0041] Initially, the mounting base 100 is connected to an external warning light and placed on the drone. The movable mechanism 200 is in a standby state, with the rotating axis 130 positioned within the transverse section 222 of the shaped hole 221. The extension arm 240 is within the clamping jaws 101, with the distal end of the extension arm 240 resting against the edge of the avoidance groove 120. The elastic member 300 is stretched, accumulating elastic potential energy.

[0042] During use, the staff controls the drone to rise, and the mounting device 10 gradually approaches the external cable 20 at a high position, so that the external cable 20 enters the clamping jaws 101. When the external cable 20 is pressed on the extension arm 240, the movable mechanism 200 will be triggered. The specific triggering process is as follows: the external cable 20 is pressed on the inclined extension arm 240, so that the rotating body 220 shifts horizontally to the left, and at this time the rotating shaft 130 slides to the intersection of the transverse section 222 and the longitudinal section 223; then, under the pulling force of the elastic member 300, the rotating body 220 moves downward, so that the rotating shaft 130 enters the longitudinal section 223; at the same time, the rotating body 220 moves downward so that the end of the extension arm 240 no longer abuts against the edge of the avoidance groove 120, and the extension arm 240 falls into the range of the avoidance groove 120. At this point, under the action of the elastic member 300, the rotating body 220 deflects around the rotation axis 130, and the extension arm 240 passes through the avoidance groove 120. The clamping arm 250 enters the clamping jaws 101 and cooperates with the inner wall of the clamping jaws 101 to clamp the external cable 20, and the movable mechanism 200 changes from the waiting state to the clamping state. The staff then controls the drone to descend, thereby hanging the hanging device 10 and the warning light on the external cable 20.

[0043] When disassembly is required, the staff pushes the reset gripping ring 260 to make the rotating body 220 rotate in the opposite direction to open, and the clamping arm 250 withdraws from the clamping jaws 101, and the external cable 20 can be separated from the clamping jaws 101; then the staff pushes the rotating body 220 upwards so that the rotating axis 130 re-enters the transverse section 222, and the end of the extension arm 240 again abuts against the edge of the avoidance groove 120, so that the hanging device 10 can be reset for next use.

[0044] Compared with the prior art, the hanging device 10 of the present application does not need to be operated by the staff during hanging, and the staff only needs to control the unmanned aerial vehicle to ascend, so that the hanging device 10 is in contact with the external cable 20 to trigger the movable mechanism 200, and then the movable mechanism 200 is autonomously deformed to clamp the external cable 20, and the hanging work is completed. After hanging, the hanging device 10 has clamping force on the external cable 20, which makes the hanging device 10 and the external cable 20 have a large friction force. Therefore, after hanging, the hanging device 10 and the warning light are not easy to shake or slide relative to the external cable 20, which ensures the stability of the hanging.

[0045] Moreover, it is emphasized that the hanging device 10 of the present application has a wide range of applications and can be compatible with cables of different sizes. In the clamping state, a clamping space is formed between the clamping arm 250 and the clamping tiger mouth 101, and as the rotating body 220 rotates, the clamping arm 250 gradually deflects, and the clamping space also correspondingly decreases until the clamping arm 250 is pressed on the external cable 20.

[0046] Further, it is found in actual use that at the moment when the movable mechanism 200 changes to the clamping state, the clamping arm 250 is suddenly pressed on the external cable 20, which is easy to cause damage to the external cable 20; especially when the external cable 20 is thin, at this time, the rotating acceleration of the rotating body 220 is large, and the force of the clamping arm 250 at the pressing moment is strong, which is easy to cause the wire core inside the external cable 20 to be bent or sheared, causing irreversible damage. Therefore, the present application further provides a limiting structure 270 on the movable mechanism 200.

[0047] Specifically, such a limiting structure 270 is arranged on the rotating body 220, which rotates together with the rotating body 220, and limits the deflection movement of the rotating body 220 by abutting 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 tiger mouth 101, thereby preventing the clamping arm 250 from excessively pressing the external cable 20 and causing damage.

[0048] Next, two specific embodiments are introduced to illustrate such a limiting structure 270;

[0049] Embodiment one:

[0050] As shown in Figure 5 and Figure 6 , the limiting structure 270 is rod-shaped, the limiting structure 270 is arranged on the rotating body 220 and cannot pass through the avoidance slot 120. When the rotating body 220 is rotated to the position, the end of the limiting structure 270 will abut against the fixed seat 100.

[0051] 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 member 300, causing the movable mechanism 200 to change to a clamping state. The limiting structure 270 rotates along 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. The position of the clamping arm 250 is fixed, and no shear force is applied to the external cable 20, thereby protecting the external cable 20.

[0052] Example 2:

[0053] like Figure 7 and Figure 8 As shown, the limiting structure 270 is an elastic clip and includes a long rod 271 and a crossbar 272. The extension arm 240 is provided with an insertion hole 241, and the end of the long rod 271 of the limiting structure 270 is clamped in the insertion hole 241. When the rotating body 220 is rotated into position, the crossbar 272 of the limiting structure 270 will abut against the inner wall of the clamping jaws 101.

[0054] 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 member 300, causing the movable mechanism 200 to change to a clamping state. The extension arm 240 passes through the avoidance groove 120 until the crossbar 272 of the limiting structure 270 abuts against the inner wall of the clamping jaws 101. At this time, the length of the long rod 271 limits the deflection angle of the rotating body 220, thereby limiting the size of the clamping space. This prevents the clamping arm 250 from excessively pressing on the external cable 20 and generating shear force, thereby protecting the external cable 20.

[0055] Furthermore, there are multiple insertion holes 241, and the multiple insertion holes 241 are evenly arranged. During use, the staff selects the appropriate insertion hole 241 according to the thickness of the external cable 20 to cooperate with the limiting structure 270, 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. Of course, it is also possible to design multiple limiting structures 270 with different lengths of long rods 271. During use, the staff can select the limiting structure 270 to change the length of the long rod 271, thereby limiting the deflection angle of the rotating body 220 and controlling the size of the clamping space, similarly serving to adapt to external cables 20 of different thicknesses.

[0056] In other embodiments, a cushioning pad (not shown) is provided on one side of the clamping arm 250 near the clamping jaws 101. When the rotating body 220 is triggered to rotate, the clamping arm 250 is pressed against the external cable 20 via the cushioning pad. This reduces the impact force exerted by the clamping arm 250 on the external cable 20, preventing excessive instantaneous shearing force and thus preventing damage to the external cable 20.

[0057] To sum up, the high-altitude wire warning light mounting device 10 based on a drone of the present invention can quickly and easily mount the warning light on the external cable 20, and is not prone to shaking or sliding after mounting, thereby achieving convenient and stable mounting operations and improving work efficiency and operational safety.

[0058] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
