Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) line laying, in particular to a UAV line laying device for power distribution networks. Background Art

[0002] A drone is an unmanned aircraft controlled by radio remote control and its own programmable control unit. It lacks a cockpit but is equipped with an autopilot, programmable control unit, and other equipment. Personnel on the ground, on ships, or at the remote control station behind the drone use radar and other equipment to track, locate, remotely control, telemeter, and transmit data. It can take off like a regular aircraft under radio remote control or be launched with a booster rocket. It can also be launched from a mother aircraft and automatically land like a regular aircraft, or it can be remotely recovered with a parachute or a net. It can be used repeatedly and is widely used for aerial reconnaissance, surveillance, communications, anti-submarine warfare, and electronic jamming.

[0003] For example, the national authorized patent announcement number CN219585584U discloses a drone line-releasing device, comprising a first fixed plate, a fixed connecting plate fixedly connected to the left outer surface of the first fixed plate, a movable connecting plate movably connected to the left outer surface of the first fixed plate, a clamping assembly fixedly connected to the front outer surface of the movable connecting plate, a second fixed disc provided on the right outer surface of the first fixed plate, a second connecting member fixedly connected to the right outer surface of the second fixed disc, a circular sleeve provided on the outer wall of the second connecting member, and the first connecting member inserted into the right outer surface of the circular sleeve. The drone line-releasing device described in the utility model is different from the traditional drone line-releasing device. The drone line-releasing device can be adjusted according to the size of drones of different models and sizes, further improving the adaptability and practicality of the drone line-releasing device, so that it can be widely used.

[0004] However, the above-mentioned drone wire-releasing device cannot automatically adjust the tightness of the wire during the pulling process, which may cause the wire to be too loose or too tight during the pulling process. If the wire is pulled too tight, it will generate a large pulling force on the drone, increase the burden on the motor, lead to increased power consumption of the drone, unstable flight, and even damage to the motor or structure. If the wire is loose, it will cause the wire to sag and get entangled with obstacles on the ground. Utility Model Content

[0005] The purpose of the present utility model is to provide a drone wire-laying device for power distribution networks, so as to solve the problem proposed in the above-mentioned background technology that the tightness of the wire cannot be automatically adjusted during the wire pulling process, which may cause the wire to be too loose or too tight during the pulling process.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The invention relates to a drone wire-laying device for power distribution network, comprising: a drone body for laying out power distribution network wires; a C-shaped frame is detachably mounted on the lower surface of the shell of the drone body; a wire-pulling mechanism is rotatably mounted in the C-shaped frame; the pulling end of the wire-pulling mechanism extends through a connecting frame; and the connecting frame is fixedly mounted on one end of both sides of the C-shaped frame.

[0008] Preferably, the wire pulling mechanism includes a winding drum, which is rotatably installed in the U-shaped frame. A guide rope is wound on the outer surface of the winding drum, and the rope end of the guide rope passes through one end of the connecting frame.

[0009] Preferably, a reduction motor is fixedly mounted on one end of the C-shaped frame, and the output shaft of the reduction motor passes through the C-shaped frame and is fixedly connected to the winding drum, so that the reduction motor can drive the winding drum to loosen and wind the guide rope.

[0010] Preferably, a tension sensor is fixedly installed in the connecting frame, a guide rope passes through the tension sensors, a signal transmitting end of the tension sensor is connected to a signal receiving end of the controller, a control output end of the controller is electrically connected to an electric control end of the reduction motor, and the controller is integrated into the drone body;

[0011] The models of the tension sensor and controller are Interface Force and Siemens respectively.

[0012] Preferably, the tension sensor is capable of detecting the tension of the guide rope in real time. When the tension is too large, the reduction motor will automatically increase the speed to increase the pay-off speed to reduce the tension.

[0013] When the tension becomes smaller, the reduction motor will slow down the rotation speed or stop rotating to stop paying out the wire, so as to prevent the cable from being too loose and sagging.

[0014] Preferably, a limited pull ring is fixedly installed on the outer surface of the guide rope passing through the connecting frame, and a lock buckle is fixedly installed on one end of the limited pull ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Through the design of the drone body, C-shaped frame, connecting frame and wire pulling mechanism, when it is necessary to lay a transmission line, the staff can fix the cable to the joint of the wire pulling mechanism, and then control the drone body to fly from one pole to another. During the flight, the drone body will rotate the wire pulling mechanism installed in the C-shaped frame to lay the guide rope to one end of the other pole. In the process of loosening and laying, the wire pulling mechanism can automatically adjust the speed at which the guide rope is released according to the tension of the guide rope, and then control the tightness of the guide rope and the speed of the line release to ensure that the guide rope is not too tight or loose. Automatic adjustment of the line-laying speed allows the drone body to adjust the line-laying rhythm in real time according to the tension of the guide rope, reducing manual intervention and making the operation smoother. After the guide rope is released, the staff can pull the thicker cable over through the guide rope, and finally connect and fix it to complete the wiring operation. This method of laying the guide rope by the drone body can quickly fly between the poles to operate, is not restricted by the terrain, and can flexibly cope with various complex environments.

Through the design of the reduction motor, reel, tension sensor, guide rope and lock, the cable is fixedly connected to the lock of the guide rope, and then the drone body is controlled to fly from one pole to another. During the flight of the drone body, the reduction motor can be started together to drive the reel to loosen the guide rope wrapped around the outer surface, so that it can be pulled along with the flight of the drone body, and the loosened guide rope can be pulled out. In the process of loosening the guide rope, the guide rope will be pulled out of the tension sensor, and the tension sensor can measure the tension value of the pulled guide rope. If the tension value of the pulled guide rope is too large, the reduction motor will automatically increase the speed of the reel to increase the pay-off. Speed, reduce the tension of the guide rope being pulled out. When the tension becomes smaller, the reduction motor will slow down the speed of the reel, or stop and suspend the pay-out to prevent the guide rope from being too loose and sagging. This real-time adjustment can ensure that the guide rope is always kept in a safe tension range, reducing the problem of the guide rope breaking or entanglement with ground buildings or hanging branches due to improper tension, thereby improving the accuracy of the entire laying process. After the guide rope is laid, the staff can pull the thicker cable over through the guide rope, and finally connect and fix it to complete the wiring operation. This method of laying the guide rope by the drone body can quickly fly between the poles to operate, is not restricted by the terrain, and can flexibly respond to various complex environments.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-4 , this embodiment provides the following technical solutions:

[0025] like Figure 1-Figure 2 As shown, a UAV wire-laying device for power distribution network includes: a UAV body 1 for laying out power distribution network, a U-shaped frame 101 is detachably installed on the lower surface of the shell of the UAV body 1, a wire-pulling mechanism 2 is rotatably installed in the U-shaped frame 101, and the traction end of the wire-pulling mechanism 2 passes through the connecting frame 102, and the connecting frame 102 is fixedly installed on one end of both sides of the U-shaped frame 101.

[0026] Through the design of the drone body 1, the U-shaped frame 101, the connecting frame 102 and the pulling mechanism 2, when it is necessary to lay a power transmission line, the staff can fix the cable to the joint of the pulling mechanism 2, and then control the drone body 1 to fly from one pole to another. During the flight, the drone body 1 will rotate the pulling mechanism 2 installed in the U-shaped frame 101 to lay the guide rope 204 to one end of another pole. In the process of loosening and laying, the pulling mechanism 2 can automatically adjust the speed at which the guide rope 204 is released according to the tension of the guide rope 204, and then can control the tightness of the guide rope 204 and the speed of the line release to ensure that the guide rope 204 is not too tight or loose. By automatically adjusting the pay-out speed, the drone body 1 can adjust the pay-out rhythm in real time according to the tension of the guide rope 204, reducing manual intervention and making the operation smoother. After the guide rope 204 is released, the staff can pull the thicker cable through the guide rope 204, and finally connect and fix it to complete the wiring operation. The method of laying the guide rope 204 by the drone body 1 can quickly fly between the poles to operate, is not restricted by the terrain, and can flexibly cope with various complex environments. The wire pulling mechanism 2 can automatically adjust the release force of the guide rope 204 according to the tension, so that the released guide rope 204 will not be too tight or too loose, avoiding human operational errors.

[0027] like Figure 3-Figure 4 As shown, the wire pulling mechanism 2 includes a winding drum 202 rotatably mounted in the U-shaped frame 101 , and a guide rope 204 is wound on the outer surface of the winding drum 202 , and the rope end of the guide rope 204 passes through one end of the connecting frame 102 .

[0028] A reduction motor 201 is fixedly mounted on one end of the C-shaped frame 101 . The output shaft of the reduction motor 201 passes through the C-shaped frame 101 and is fixedly connected to the winding drum 202 , so that the reduction motor 201 can drive the winding drum 202 to release and reel the guide rope 204 .

[0029] A tension sensor 203 is fixedly installed in the connecting frame 102. A guide rope 204 passes through the tension sensor 203. The signal transmitting end of the tension sensor 203 is connected to the signal receiving end of the controller. The control output end of the controller is electrically connected to the electric control end of the reduction motor 201. The controller is integrated into the drone body 1.

[0030] The models of the tension sensor 203 and the controller are Interface Force and Siemens respectively.

[0031] The tension sensor 203 can detect the tension of the guide rope 204 in real time. When the tension is too large, the reduction motor 201 will automatically increase the speed and increase the pay-off speed to reduce the tension.

[0032] When the tension becomes smaller, the reduction motor 201 will slow down the rotation speed or stop rotating to stop paying out the wire, so as to prevent the wire from being too loose and sagging.

[0033] A limited pull ring 206 is fixedly installed on the outer surface of the guide rope 204 passing through the connecting frame 102, and a lock buckle 205 is fixedly installed on one end of the limited pull ring 206.

[0034] Through the design of the reduction motor 201, the winding drum 202, the tension sensor 203, the guide rope 204 and the lock 205, the cable is fixedly connected to the lock 205 of the guide rope 204, and then the drone body 1 is controlled to fly from one pole to another. During the flight of the drone body 1, the reduction motor 201 can be started at the same time to drive the winding drum 202 to loosen the guide rope 204 wrapped around the outer surface, so that it can be pulled along with the flight of the drone body 1, and the loosened guide rope 204 can be pulled out. In the process of loosening the guide rope 204, the guide rope 204 will be pulled out in the tension sensor 203, and the tension sensor 203 can measure the tension value of the pulled guide rope 204. If the tension value of the pulled guide rope 204 is too large, the reduction motor 201 will automatically accelerate the winding drum. The rotation speed of the reel 202 increases the pay-out speed and reduces the tension of the guide rope 204. When the tension becomes smaller, the reduction motor 201 will slow down the rotation speed of the reel 202, or stop and suspend the pay-out to prevent the guide rope 204 from being too loose and sagging. This real-time adjustment can ensure that the guide rope 204 always remains within a safe tension range, reducing the problem of the guide rope 204 breaking or getting entangled in ground buildings or hanging branches due to improper tension, thereby improving the accuracy of the entire laying process. After the guide rope 204 is released, the staff can pull the thicker cable through the guide rope 204, and finally connect and fix it to complete the wiring operation. The way of laying the guide rope 204 by the drone body 1 can quickly fly between the poles to operate, is not restricted by the terrain, and can flexibly cope with various complex environments.

[0035] According to the above technical solution, the working steps of this solution are summarized and sorted out: when it is necessary to lay a transmission line, the staff can fix the cable in the lock 205 of the guide rope 204, and then control the drone body 1 to fly from one pole to another. During the flight of the drone body 1, the reduction motor 201 can be started at the same time to drive the reel 202 to loosen the guide rope 204 wrapped around the outer surface, so that it can be pulled along with the flight of the drone body 1, and then the loosened guide rope 204 can be pulled out, and in the process of loosening the guide rope 204, the guide rope 204 will be pulled out in the tension sensor 203, so that the tension sensor 203 can be made to move. Measure the tension value of the pulled guide rope 204. If the tension value of the pulled guide rope 204 is too large, the reduction motor 201 will automatically increase the rotation speed of the take-up drum 202 to increase the pay-out speed and reduce the tension of the guide rope 204. When the tension becomes smaller, the reduction motor 201 will slow down the rotation speed of the take-up drum 202, or stop and suspend the pay-out to prevent the guide rope 204 from being too loose and sagging. After the guide rope 204 is released, the staff can use the guide rope 204 to pull the thicker cable over, and finally connect and fix it to complete the wiring operation. Then the reduction motor 201 can be started to reverse and drive the take-up drum 202 to reel in the released guide rope 204.

[0036] In summary: by adjusting the tension of the guide rope 204 in real time, it can ensure that the guide rope 204 always remains in a safe tension range, reducing the problem of the guide rope 204 breaking or getting entangled in ground buildings or hanging on branches due to improper tension, thereby improving the accuracy of the entire laying process.
