[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related 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 keep it stable 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 opened 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 with an external warning light.

[0035] like Figure 4 and Figure 5As shown, the movable mechanism 200 includes a rotating body 220 disposed on the rotating shaft 130, and a special-shaped hole 221 is opened on the rotating body 220. The rotating shaft 130 passes through the special-shaped hole 221, and the 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 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 obliquely and at an angle, so that a bell-mouth structure is formed between the two fork arms 110. In this way, the external cable 20 can enter the clamping jaws 101 more easily from the opening.

[0038] In this embodiment, the rotating body 220 is composed of two trigger plates 224 (such as Figure 5 The two trigger plates 224 are formed into a whole by rotating the shaft 130 and the linkage rod 230 and realize linkage. The number of the avoidance grooves 120 is the same as the number of the trigger plates 224. Preferably, a reset gripping ring 260 is provided on the rotating body 220, and the reset gripping ring 260 is used to facilitate the reset of the rotating body 220, that is, to change 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 when the 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 fixing base 100 is connected to the external warning light and is placed on the drone. At this time, the movable mechanism 200 is in a waiting state, the rotating shaft 130 is located in the transverse section 222 of the special-shaped hole 221, the extension arm 240 is in the clamping jaws 101, and the end of the extension arm 240 is against the edge of the avoidance groove 120, and the elastic member 300 is stretched and accumulates 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 place, 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 is horizontally shifted 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 time, under the action of the elastic member 300, the rotating body 220 deflects around the rotating shaft 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. Then the staff controls the drone to descend, so that the hanging device 10 and the warning light are hung 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 detached from the clamping jaws 101; then the staff pushes the rotating body 220 upwards, so that the rotating axis 130 re-enters the horizontal 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 mounting device 10 of the present invention does not require the staff to operate during mounting. The staff only needs to control the drone to rise, so that the mounting device 10 contacts the external cable 20 to trigger the movable mechanism 200, and then the movable mechanism 200 deforms autonomously to clamp the external cable 20 to complete the mounting work. After mounting, the mounting device 10 has a clamping force on the external cable 20, which makes the mounting device 10 and the external cable 20 have a large friction force. Therefore, after mounting, the mounting device 10 and the warning light are not easy to shake or slide relative to the external cable 20, ensuring the stability of the mounting.

[0045] It should be emphasized that the mounting device 10 of the present invention has a wide range of applications and is compatible with cables of different sizes. In the clamping state, a clamping space is formed between the clamping arm 250 and the clamping jaws 101. As the rotating body 220 rotates, the clamping arm 250 gradually deflects, and the clamping space is correspondingly reduced until the clamping arm 250 is pressed on the external cable 20.

[0046] Furthermore, it is found in actual use that at the moment when the movable mechanism 200 changes to the clamping state, the clamping arm 250 suddenly presses on the external cable 20, which is easy to cause damage to the external cable 20; especially when the external cable 20 is thin, the rotation acceleration of the rotating body 220 is large, and the clamping force of the clamping arm 250 is strong, which is easy to cause the wire core inside the external cable 20 to be bent or sheared, causing irreversible damage. For this reason, the present invention also sets a limit structure 270 on the movable mechanism 200.

[0047] Specifically, this type of limiting structure 270 is provided on the rotating body 220, and rotates with the rotating body 220, and limits the deflection movement of the rotating body 220 by abutting against or moving away from the fixing 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 jaws 101, thereby preventing the clamping arm 250 from excessively pressing the external cable 20 to cause damage.

[0048] Next, two specific embodiments are introduced to illustrate this type of limiting structure 270;

[0049] Embodiment 1:

[0050] like Figure 5 and Figure 6 As shown, the limiting structure 270 is rod-shaped, and the limiting structure 270 passes through the rotating body 220 and cannot pass through the avoidance groove 120. When the rotating body 220 rotates to the right position, the end of the limiting structure 270 will be held against the fixing 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 pulling force of the elastic member 300, so that the movable mechanism 200 changes to a clamping state. The limiting structure 270 rotates with the rotating body 220 until the limiting structure 270 abuts against the fixed seat 100. At this time, 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 generated on the external cable 20, thereby protecting the external cable 20.

[0052] Embodiment 2:

[0053] like Figure 7 and Figure 8 As shown, the limiting structure 270 is an elastic clip, and the limiting structure 270 is provided with a long rod 271 and a cross bar 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 to the right position, the cross bar 272 of the limiting structure 270 will be 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 pulling force of the elastic member 300, so that the movable mechanism 200 changes to a clamping state. The extension arm 240 passes through the avoidance groove 120 until the cross bar 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, so that the clamping arm 250 will not excessively press the external cable 20 to form a shear force, thereby protecting the external cable 20.

[0055] Furthermore, there are multiple plug holes 241, and the multiple plug holes 241 are evenly arranged. When in use, the staff selects the appropriate plug hole 241 to cooperate with the limiting structure 270 according to the thickness of the external cable 20, so as to change the deflection angle of the rotating body 220, control the size of the clamping space, and thus adapt to external cables 20 of different thicknesses. Of course, multiple limiting structures 270 with different lengths of long rods 271 can also be designed. When in use, the staff selects 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, which also plays the role of adapting to external cables 20 of different thicknesses.

[0056] In other embodiments, a buffer 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 will be pressed on the external cable 20 through the buffer pad. In this way, the impact force of the clamping arm 250 on the external cable 20 can be reduced, so that the instantaneous shear force will not be too large, thereby preventing damage to the external cable 20.

[0057] To sum up, the drone-based high-altitude wire warning light mounting device 10 of the present invention can conveniently and quickly mount the warning light on the external cable 20, and it is not easy to shake or slide after mounting, thereby realizing convenient and stable mounting operation, improving work efficiency and operational safety.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
