Description

Technical Field

[0001] This utility model belongs to the field of power maintenance, specifically a safety fixing bracket for unmanned aerial vehicles (UAVs) to drop insulating ropes for live-line maintenance. Background Technology

[0002] In live-line maintenance of power lines, it is often necessary to accurately attach insulating ropes to designated conductor and ground wire positions. Traditional rope throwing methods suffer from rope wear, reduced insulation performance due to conductor and ground wire and ground dust, fixed rope length requirements, limitations on drone flight paths and payloads, long attachment and dismantling times, and significant terrain constraints. Furthermore, safety is difficult to guarantee in complex live-line maintenance environments. With the increasingly widespread application of drone technology in the power industry, using drones to carry ropes and drop them to target locations offers a new approach to solving these problems.

[0003] However, the existing wire-hanging auxiliary tools used with drones are not yet perfect. There is a lack of a specially designed, easy-to-install, stable, easy-to-operate, safe and efficient safety fixing bracket, which makes it difficult to efficiently meet the needs of complex power construction conditions. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a safety fixing bracket for throwing insulating ropes from a drone used for live-line maintenance, thus solving the problem of inconvenient installation in existing technologies.

[0005] A safety fixing bracket for throwing insulated ropes from a drone used for live-line maintenance includes:

[0006] A fixed frame, wherein a suspension mechanism is installed on the top of the fixed frame, and elastic buckles are connected to both sides of the bottom of the fixed frame;

[0007] The hanging body is slidably installed on the periphery of the elastic buckle. A guide tube is installed on the top of the hanging body and is sleeved on the periphery of the elastic buckle. A U-shaped groove is opened on the hanging body. A guide mechanism is connected to the front end of the hanging body. A rope assembly hole is opened on the side of the hanging body.

[0008] An adjustment mechanism is installed on the top of the hanging body;

[0009] The adjustment mechanism includes a horizontal plate installed on the top of the hanging body, an adjusting bolt slidably installed inside the horizontal plate, and a screw hole adapted to the adjusting bolt on the top of the hanging body.

[0010] Preferably, the inner wall of the U-shaped groove is provided with an anti-wear layer, and the hanging wire body is made of high-strength, lightweight aluminum alloy.

[0011] Preferably, the guiding mechanism includes a guide plate detachably mounted on the front end of the hanging body, and the guide plate is connected to the hanging body by a connecting bolt.

[0012] Preferably, the elastic buckle is composed of a cylinder and a square column, and the diameter of the cylinder is the same as the diameter of the square column. The inside of the hanging wire body is provided with a square hole that allows the square column to slide, and the inside of the conduit is provided with a round hole that matches the cylinder.

[0013] Preferably, the suspension mechanism includes a support leg and a plurality of hooks, the bottom of the support leg being connected to the top of the fixing frame, and the hooks being distributed around the periphery of the support leg.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through the cooperation of the elastic buckle, the fixing frame and the suspension mechanism, facilitates the quick connection and assembly between the device and the drone during use. At the same time, after the ground wire enters the U-shaped groove, it can automatically seal the opening of the U-shaped groove under the action of gravity, preventing the ground wire from falling out of the U-shaped groove opening, making the connection between the device and the ground wire more convenient.

[0016] 2. This utility model reduces the probability of the rope directly contacting the ground wire by using the main body of the hanging wire, reduces the probability of the rope getting dirty, and improves the safety performance of the rope. When the drone is throwing the rope, it ensures accuracy and smoothness, reduces errors caused by rope problems, and avoids safety accidents caused by errors. At the same time, by selecting the material of the hanging wire body and simplifying the operation steps, it can reduce the load on the drone, shorten the drone assembly time, and reduce energy consumption.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown:

[0025] Example 1: This utility model provides a safety fixing bracket for throwing insulating ropes onto a drone for live-line maintenance, comprising:

[0026] The fixed frame 3 has a suspension mechanism 4 installed on its top and elastic buckles 2 connected to both sides of its bottom.

[0027] The hanging body 1 is slidably installed on the periphery of the elastic buckle 2. A guide tube 11 is installed on the top of the hanging body 1. The guide tube 11 is sleeved on the periphery of the elastic buckle 2. A U-shaped groove 7 is opened on the hanging body 1. A guide mechanism 9 is connected to the front end of the hanging body 1. A rope assembly hole 10 is opened on the side of the hanging body 1.

[0028] Adjustment mechanism 5 is installed on the top of the hanging body 1;

[0029] The adjustment mechanism 5 includes a horizontal plate 501 installed on the top of the hanging body 1. An adjusting bolt 502 is slidably installed inside the horizontal plate 501. A screw hole 6 adapted to the adjusting bolt 502 is opened on the top of the hanging body 1.

[0030] Among them, the elastic latch 2 can seal the opening of the U-shaped groove 7.

[0031] As can be seen from the above, when in use, the suspension mechanism 4 is hooked by the buckle on the rope, and the other end of the rope is connected to the drone. After the connection, the insulated rope is passed through the rope assembly hole 10 for connection. After the adjusting bolt 502 is passed through the horizontal plate 501 and connected to the screw holes 6 at different positions on the top of the hanging body 1, the two hanging bodies 1 are connected into a whole. At the same time, the center of gravity of the device after it leaves the ground is changed when the drone pulls the device up, so that the device maintains a certain angle to facilitate the next step of suspension assembly.

[0032] After the connection between the device and the drone is completed, the drone is started. During the ascent, the drone pulls the suspension mechanism 4 upward through the rope. During the ascent, the suspension mechanism 4 pulls the elastic buckle 2 upward through the fixed frame 3, causing the elastic buckle 2 located at the opening of the U-shaped groove 7 to retract into the interior of the hanging body 1. After entering the interior of the hanging body 1, the elastic buckle 2 pulls both hanging bodies 1 upward at the same time, thereby achieving take-off.

[0033] Driven by the drone, the device rises above the ground wire and then slowly descends, allowing the ground wire to enter the U-shaped groove 7 through the slot. During the guidance process, the guide mechanism 9 expands the entry range of the U-shaped groove 7. The ground wire, at the bottom structure of the guide mechanism 9, smoothly enters the U-shaped groove 7 under the guidance of the guide mechanism 9. After the ground wire enters the U-shaped groove 7, the drone slowly descends again. After the elastic lock 2, the fixing frame 3, and the suspension mechanism 4 lose the traction of the drone, they automatically move downward under their own weight, causing the elastic lock 2 to re-seal the slot of the U-shaped groove 7. After sealing, the buckle on the rope is released from the hook by lowering the drone's height, thus completing the assembly.

[0034] Through the cooperation between the elastic buckle 2, the fixing frame 3 and the suspension mechanism 4, it is easy to quickly connect and assemble the device with the drone during use. At the same time, after the ground wire enters the U-shaped groove 7, it can automatically seal the opening of the U-shaped groove 7 under the action of gravity to prevent the ground wire from falling out of the opening of the U-shaped groove 7, making the connection between the device and the ground wire more convenient.

[0035] As attached Figure 1 Appendix Figure 2 and attached Figure 4 As shown:

[0036] Specifically, regarding the aforementioned U-shaped groove 7, the inner wall of the U-shaped groove 7 is provided with an anti-wear layer 8, and the hanging body 1 is made of high-strength, lightweight aluminum alloy.

[0037] As can be seen from the above, the wear-resistant layer 8 on the inner wall of the U-shaped groove 7 can ensure the wear between the hanging body 1 and the ground wire during use, reducing frictional resistance. The hanging body 1, made of high-strength and lightweight aluminum alloy, can ensure a certain strength while reducing the weight of 1, reducing the load of the drone and reducing energy consumption.

[0038] As attached Figure 1 Appendix Figure 2 and attached Figure 4 As shown:

[0039] Specifically, regarding the aforementioned guide mechanism 9, the guide mechanism 9 includes a guide plate 901 that is detachably installed at the front end of the hanging body 1, and the guide plate 901 is connected to the hanging body 1 by a connecting bolt 902.

[0040] The shape of the guide plate 901 is designed using computer-aided design (CAD) software based on the movement trajectory of the device and the rope.

[0041] As can be seen from the above, by connecting bolt 902, guide plate 901 is assembled onto wire hanging body 1. After assembly, the angle at the opening of U-shaped groove 7 can be expanded. When using drone to assemble the device, guide plate 901 can effectively guide the ground wire to smoothly enter the U-shaped groove 7 on wire hanging body 1, thereby shortening the alignment time and improving the assembly efficiency.

[0042] As attached Figure 3 As shown:

[0043] Specifically, regarding the aforementioned elastic buckle 2, the elastic buckle 2 is composed of a cylinder and a square column, and the diameter of the cylinder is the same as the diameter of the square column. The inside of the hanging body 1 is provided with a square hole that allows the square column to slide, and the inside of the guide tube 11 is provided with a round hole that matches the cylinder.

[0044] As can be seen from the above, when the fixing frame 3 is pulled upward by the drone, it will drive the elastic buckle 2 to slide upward at the same time, so that the cylindrical and square pillars on the elastic buckle 2 enter the square hole on the hanging body 1. Since the square pillar cannot pass through the cylindrical hole inside the guide tube 11, the square pillar can not continue to move upward after it moves to the top of the square hole inside the hanging body 1, thereby pulling the hanging body 1 as a whole to rise. When the assembly is completed, during the descent of the fixing frame 3, the cylindrical and square pillars on the elastic buckle 2 will automatically reset under the action of gravity to seal the opening of the U-shaped groove 7, preventing the hanging body 1 from falling off the ground wire, thereby completing the assembly.

[0045] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown:

[0046] Example 2: This example is basically the same as the previous example, except that...

[0047] The suspension mechanism 4 includes legs and several hooks. The bottom of the legs is connected to the top of the fixed frame 3, and the hooks are distributed around the perimeter of the legs.

[0048] The preferred number of hooks is three, with the same distance between each hook, and the hooks are quickly attached to the drone using rope clips.

[0049] As can be seen from the above, when in use, the buckle on the rope is hooked onto the hook on the suspension mechanism 4, and the other end of the rope is securely tied to the drone safety fixing bracket as required. During the drone's ascent, the device is lifted by the hook and outriggers on the suspension mechanism 4. When it is necessary to detach, the drone is slowly lowered to allow the buckle on the rope to detach from the hook, thus completing the assembly. By connecting the buckle on the rope to hooks at different positions on the suspension mechanism 4, the center of gravity of the device during the ascent can be changed.

[0050] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
