Description

TECHNICAL FIELD

[0001] The present application relates to the field of cable and optical cable construction, in particular to a high-altitude power distribution line operation platform based on unmanned aerial vehicle technology. BACKGROUND

[0002] With the accelerated promotion of new infrastructure construction in China, network facilities such as optical cables, mobile communications, industrial internet and 5G have gradually formed a three-dimensional communication network system with global coverage and multi-network cooperation. This system not only is the core support for the development of digital economy, but also is deeply integrated into the energy field, providing a solid communication guarantee for the intelligent upgrading of power distribution networks. As the key carrier connecting the power system and the terminal users, the safe and stable operation of the power distribution line is directly related to the power supply reliability of industrial production, residential life and various network facilities. Especially under the background of rapid growth of new loads such as 5G base stations and Internet of Things terminals, the operation quality and efficiency of the power distribution line are facing higher requirements.

[0003] Currently, the power distribution line is mostly distributed in complex areas such as urban streets, rural fields and mountainous forests. Some lines need to cross rivers, highways and other special terrains, and the operating environment often faces multiple risks such as wind and rain, icing, lightning and external damage. Therefore, regular inspection, maintenance and fault troubleshooting of high-altitude operation have become the core link of power distribution network operation and maintenance. However, the traditional high-altitude power distribution line operation mode is still mainly based on manual tower climbing and insulated boom truck operation. However, in actual operation, manual tower climbing operation depends on the high-altitude operation skills of the operator. Even if perfect protective equipment is provided, there are still safety hazards such as falling and electric shock, especially in bad weather conditions such as humidity and strong wind, the operation risk increases exponentially. Although the insulated boom truck can provide a relatively stable operation platform for the operator, it is limited by the terrain conditions and cannot reach the operation point in mountainous, hilly and narrow lane areas. Moreover, the equipment itself has poor mobility and cannot quickly respond to sudden failures. SUMMARY

[0004] To solve the above technical problems existing in the operation of power distribution line inspection, maintenance and other operations, the present application provides a high-altitude power distribution line operation platform based on unmanned aerial vehicle technology.

[0005] The technical scheme of the present application is as follows: The high-altitude power distribution line operation platform based on unmanned aerial vehicle technology comprises: The mounting main frame is an arc-shaped structure integrally formed, comprising a left limiting frame and a right limiting frame, both of which are arc-shaped and integrally formed, and the bottoms of the two are curved downward, a receiving cavity is formed in the middle of the left limiting frame and the right limiting frame, and the upper end of the right limiting frame extends toward the left limiting frame and forms an open structure with the left limiting frame; The first connecting frame is integrally formed with the left and right limiting frames and is used for mounting the operation equipment; The mounting auxiliary frame is arranged in an arc shape and is hingedly connected to the end of the right limiting frame, and is located in the accommodating cavity in a natural state, and the hinged part of the mounting auxiliary frame is located in the opening structure and is spaced apart from the left limiting frame in the natural state. The unmanned aerial vehicle is electrically connected to the operation equipment and can receive the output signal of the operation equipment, and the unmanned aerial vehicle can supply power to the operation equipment. The unmanned aerial vehicle is electrically connected to the operation equipment and can receive the output signal of the operation equipment, and the unmanned aerial vehicle can supply power to the operation equipment.

[0006] The right limiting frame comprises a main body segment connected to the left limiting frame, and the main body segment is integrally formed with an extension segment at the top end thereof.

[0007] In order to improve the stability of the cable mounting, the extension segment is arranged in an arc shape and is curved upward, and the end of the extension segment away from the main body segment is used for hingedly connecting the mounting auxiliary frame.

[0008] In order to improve the balance after mounting, the second connecting frame is arranged outside the arc top of the extension segment, and the second connecting frame is used for connecting the unmanned aerial vehicle.

[0009] In order to arrange the extension segment and the left connecting frame in a spaced apart manner, facilitate the mounting of the cable, the curvature of the left limiting frame is smaller than the curvature of the main body segment of the right limiting frame, and the highest point of the main body segment is not lower than the highest point of the left limiting frame.

[0010] In order to ensure the stability of the cable and the mounting auxiliary frame, the curvature of the mounting auxiliary frame is consistent with the curvature of the extension segment, and the end of the extension segment is hingedly connected to the arc top of the mounting auxiliary frame.

[0011] In order to facilitate the electrical connection of the unmanned aerial vehicle and the operation equipment, the right limiting frame, the first connecting frame and the second connecting frame are all arranged in a hollow structure and are in communication with each other, and the transmission lead is connected between the unmanned aerial vehicle and the operation equipment.

[0012] It also includes a ranging sensor, which is electrically connected to the control system. It can acquire the position information of the cable when it is outside the opening structure and transmit the signal to the ground control terminal in real time. It is located inside the left limit frame near the upper end, and its signal output end is vertically upward and can pass through the opening structure.

[0013] It also includes a displacement sensor, which is electrically connected to the control system. It can obtain the cable position information when the cable enters the opening structure and transmit the distance information to the ground control terminal in real time. The displacement sensor is located at the bottom of the cavity and its signal transmitting end is coplanar with the first connecting frame in the vertical direction.

[0014] The method for high-altitude power distribution line operation based on drone technology, which utilizes the aforementioned drone-based high-altitude power distribution line operation platform, includes the following steps: S1: Initial drone positioning, start the drone, send flight commands to the control system through the ground control terminal, so that the drone can fly the main frame to a position under the cable and close to it.

[0015] S2: Opening position guidance and positioning, fine-tuning the drone's position until the control system obtains the cable position information sent by the ranging sensor, slowly raises the drone and controls it to move away from the left limit frame for fine-tuning, so that the cable enters the opening structure; S3: The cable enters the preset position of the receiving cavity and is detected. The drone is controlled to move according to the operation in S2 until the displacement sensor transmitted by the control system detects that the cable has reached the preset position of the receiving cavity. The drone is then lifted and its current position is maintained. S4: Attach the subframe and attach the cable to control the drone to fall slowly. Use the cable to push the right side of the hinge of the subframe to rotate upward until the distance information fed back by the displacement sensor transmitted by the control system no longer changes, and stop the drone from falling. S5: Start-up and operation of the work equipment. The ground control terminal sends a command to the UAV to start the work equipment. After receiving the command, the UAV starts the work equipment through its built-in control system and controls the work equipment to operate according to the preset program. S6: Data Acquisition and Transmission. During operation, the equipment collects relevant data and information. The UAV transmits the collected data and information back to the ground control terminal in real time. The ground control terminal displays, stores, and analyzes the received data and information. Based on the data and information, it controls the UAV to move the equipment along the cable length to perform the operation. S7: Operation completion and recovery. After the operation is completed, the drone is controlled to detach from the cable and return to the designated location.

[0016] The beneficial effects of this invention are as follows: This invention is a high-altitude power distribution operation platform based on drone technology. Compared with traditional manual tower climbing operations, which are prone to falls and electric shock risks, and the limitations of insulated bucket trucks in mountainous areas and narrow alleys where they are difficult to reach the work point, this operation platform uses a drone to drive the main frame to fly precisely to the cable position. There is no need for personnel to climb the tower or rely on large equipment, reducing the safety hazards of manual high-altitude operations. Even in adverse weather conditions such as dampness, it can be remotely controlled through a ground control terminal, avoiding the superposition of risks caused by environmental factors. The left and right limit frames of the main frame form an arc-shaped receiving cavity. With the help of the rotatable sub-frame, the cable can push the sub-frame to rotate through the opening structure and be stably locked into the receiving cavity. It is suitable for power distribution cables of different diameters. Moreover, the high mobility of the drone can easily cross special terrains such as rivers, highways and mountainous forests, breaking through the terrain limitations of traditional operation equipment. The dual positioning of distance and displacement sensors can obtain cable position information in real time and feed it back to the ground terminal. With standardized operation steps, it can achieve precise control of cable splicing and operation, reducing the error of manual operation. The hollow structure of the mounting frame provides an internal channel for the transmission wires, which protects the wires from damage by the external environment and prevents the cables from getting tangled and affecting the operation. At the same time, the drone has both power supply and data transmission functions, and can transmit the data collected by the operating equipment back to the ground terminal in real time, enabling instant analysis of operation and maintenance data and greatly shortening the troubleshooting cycle.

Detailed Implementation

[0019] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. It should be noted that these embodiments are provided to enable a more thorough understanding of this disclosure and to fully convey the scope of this disclosure to those skilled in the art. This disclosure can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0020] Example This embodiment discloses a high-altitude power distribution line operation platform based on UAV 4 technology, aiming to solve the problems of high safety hazards, poor terrain adaptability, and slow emergency response associated with traditional manual tower climbing and insulated bucket truck operations. Through the collaborative design of an integrated arc-shaped mounting structure, precise sensor positioning, and UAV 4 remote control, it enables unmanned and safe high-altitude operations such as cable inspection, temperature measurement, fault diagnosis, and insulation coating. It is suitable for the power distribution line maintenance needs of complex areas such as urban streets, rural fields, and mountainous forests. Its specific structure, core components, and operating methods are as follows (see attached figure). Figures 1-3 It includes the main mounting frame 1, which has an overall arc-shaped structure. Its length in the cross-sectional direction can be set as needed to ensure sufficient length along the cable direction, increasing the contact area with the cable during mounting and effectively dispersing the impact force during cable mounting, thus avoiding localized stress concentration. It includes a left limiting frame 11 and a right limiting frame 12. Figure 1 The dashed line in the middle represents the dividing line between the left limiting frame 11 and the right limiting frame 12. Both are arc-shaped and integrally formed, with the bottom curving downwards. The left limiting frame 11 and the right limiting frame 12 enclose each other to form a receiving cavity 13 for accommodating cables. The width of the receiving cavity 13 should be adapted to the diameter range of the current mainstream cables.

[0021] In this embodiment, combined with Figure 2The right limiting frame 12 includes a main body section 121 connected to the left limiting frame 11. An arc-shaped extension section 122 is integrally formed at the top of the main body section 121, facing the left limiting frame 11. The extension section 122 curves upwards, with one end away from the main body section 121 used for hinged connection to the sub-frame 3. The other end of the extension section 122 is on the same horizontal line as this end, ensuring balanced force distribution when the sub-frame 3 rotates. A first connecting frame 15 is integrally formed on the outer side of the connection point between the left limiting frame 11 and the right limiting frame 12, used to fix the operating equipment 2, such as a high-definition inspection camera, infrared thermometer, ultrasonic flaw detector, etc., adapting to the equipment installation requirements of different maintenance scenarios. A second connecting frame 16 is integrally formed on the outer side of the arc-shaped apex of the extension section 122. The second connecting frame 16 and the first connecting frame 15 are coplanar in the vertical direction, ensuring the overall center of gravity of the drone 4 is stable after mounting, avoiding off-center loading during flight. The curvature of the left limiting frame 11 is less than that of the main body section 121 of the right limiting frame 12, and the highest point of the main body section 121 is not lower than the highest point of the left limiting frame 11. This design can guide the cable to slide quickly into the receiving cavity 13, and also ensure that the arc top of the extension section 122 can be set vertically upward, while preventing the cable from falling off from the left side during operation. In addition, the right limiting frame 12, the first connecting frame 15, and the second connecting frame 16 are all set as hollow structures, and the three are internally connected. The transmission wire 5 can be set inside, providing a hidden wiring channel for the transmission wire 5, avoiding the wire from being exposed to the outside and being corroded by wind and rain or tangled with the cable. The transmission wire 5 enters from the first connecting frame 15, extends along the inside of the right limiting frame 12 to the second connecting frame 16 and exits. The two ends of the transmission wire 5 are respectively connected to the drone 4 and the working equipment 2 to realize the electrical connection between the two. On the one hand, the drone 4 can supply power to the working equipment 2, and on the other hand, it can realize the signal transmission between the two.

[0022] Based on the above structure, the mounting sub-frame 3 is designed as an arc shape, with its curvature matching that of the extension section 122 of the right limiting frame 12, ensuring a tight fit with the extension section 122 when mounted. The arc-shaped top of the mounting sub-frame 3 is hinged to the end of the extension section 122 of the right limiting frame 12. In its natural state, the mounting sub-frame 3 is located entirely within the receiving cavity 13, with its hinged part on the left side within the opening structure 14 and maintaining a 5-8cm gap from the left limiting frame 11, providing a reserved channel for cable entry. Even if the cable diameter is larger than this size, it can still enter the receiving cavity 13 by pushing the mounting sub-frame 3 to rotate during the entry process. However, the purpose of this size design is to ensure that the gap distance is larger than the diameter of most commonly used cables. When mounted, the cable pushes the right side of the hinged part of the mounting sub-frame 3 upward under the action of gravity until the sub-frame abuts against the right limiting frame 12. At this time, the mounting sub-frame 3, the left limiting frame 11, and the right limiting frame 12 together form a limiting space.

[0023] In this embodiment, the UAV 4 is a six-rotor heavy-duty UAV 4, which features high hovering accuracy, strong wind resistance, and long endurance. Its fuselage bottom is connected to the second connecting frame 16, which is easy to disassemble and maintain. The UAV 4 has a built-in high-performance control system, which integrates a flight control unit, a signal processing unit, and a power supply management unit. The control system and the ground control terminal are wirelessly connected via 5G and Beidou dual-mode, which ensures both the stability of signal transmission and centimeter-level positioning accuracy.

[0024] The drone 4 and the operating equipment 2 are electrically connected via a transmission cable 5. The transmission cable 5 enters from the inlet of the first connecting frame 15, extends along the hollow interior of the right limiting frame 12, exits through the outlet of the second connecting frame 16, and finally connects to the power supply and signal interface of the drone 4. The drone 4 can provide a stable DC power supply to the operating equipment 2 and receive the output signals of the operating equipment 2, transmitting them back to the ground control terminal in real time. The ground control terminal is an industrial-grade tablet computer with built-in dedicated operation and maintenance software, supporting functions such as command issuance, status monitoring, data storage and analysis.

[0025] It should be noted that, in combination Figure 2 The dashed arrows in the diagram indicate the direction of sensor signal transmission. To improve efficiency and accuracy when mounting cables, a ranging sensor 6 and a displacement sensor 7 are also included, both using laser sensors. The ranging sensor 6 is installed inside the left limiting frame 11 near the upper end, with its signal output end pointing vertically upwards and able to pass through the opening structure 14. The ranging sensor 6 is electrically connected to the control system and is mainly used for accurate identification of the initial position of the cable. When the cable is outside the opening structure 14, it can obtain the vertical distance information between the cable and the opening structure 14 in real time and transmit the signal to the ground control terminal, providing data support for the fine-tuning of the UAV 4. In addition, the displacement sensor 7 is installed at the bottom of the receiving cavity 13, and its signal transmitting end is coplanar with the first connecting frame 15 in the vertical direction, ensuring that the detection direction is consistent with the cable mounting path. The displacement sensor 7 is electrically connected to the control system. When the cable enters the opening structure 14, it can monitor the position change of the cable in the receiving cavity 13 in real time, accurately determine whether the cable has reached the preset mounting position, and prompt the ground operator to adjust to the preset position as soon as possible. It should also be noted that both the distance sensor 6 and the displacement sensor 7 are electrically connected to the UAV 4 through the transmission wire 5. The transmission wire 5 is arranged in the hollow left limit frame 11 and right limit frame 12 and passes through them to connect with them, so as to provide power to them.

[0026] The above is a description of the work platform. In conjunction with this work platform, a work method has also been designed, including the following steps: S1: Initial Positioning of UAV 4: The operator starts UAV 4 in a safe area. After receiving the command, the control system drives UAV 4, carrying the main frame 1, to fly along the preset route until it reaches a position 10-15m below the target cable and hovers. It should be noted that guide rails 8 are provided outward and upward at the end of the left limiting frame 11, which is equivalent to enlarging the opening structure 14, allowing the cable to enter the opening structure 14 on one side of the guide rail 8 more quickly. In addition, for overall balance, the same guide rails 8 are provided at the symmetrical position of the right limiting frame 12, making the whole structure more balanced and stable.

[0027] S2: Opening position guidance and positioning: Activate the ranging sensor 6, and fine-tune the height and horizontal position of the UAV 4 through the ground control terminal. When the ranging sensor 6 detects the cable signal and transmits it to the control system, the ground terminal screen displays the relative position of the cable and the opening structure 14. Slowly raise the height of the UAV 4, and at the same time control the UAV 4 to fine-tune in the direction away from the left limit frame 11, so as to guide the cable to accurately enter the opening structure 14 between the left limit frame 11 and the right limit frame 12.

[0028] S3: Cable enters the pre-set position detection of the receiving cavity 13: Continue to control the movement of the drone 4 according to the operation rhythm of S2. The displacement sensor 7 transmits the position data of the cable in the receiving cavity 13 to the ground terminal in real time. When the cable reaches the pre-set position in the middle of the receiving cavity 13, the control system sends a positioning completion signal to the ground terminal, and the operator immediately stops lifting the drone 4 and maintains the current hovering state.

[0029] S4: Cable mounting on subframe 3: The ground terminal controls the drone 4 to descend slowly. Under the influence of gravity, the cable presses against the right side of the hinge of subframe 3, pushing the subframe to rotate upward. When the subframe rotates to abut against the right limit frame 12, the cable is completely fixed in the receiving cavity 13. At this time, the distance information fed back by displacement sensor 7 no longer changes, the control system sends a mounting lock signal, and the operator stops the descent of drone 4.

[0030] Furthermore, it should be noted that limiting blocks 9 can be installed at both ends of the bottom of the mounting sub-frame 3. These limiting blocks 9 are located at the ends of the mounting sub-frame 3, and two limiting blocks 9 are symmetrically arranged relative to the arc top of the mounting sub-frame. They can limit the movement at the edge to prevent the cable from being separated from the mounting sub-frame 3 when subjected to sudden external force.

[0031] S5: Start-up and Operation of Operation Equipment 2: Select the preset operation mode through the ground control terminal and send a start command to UAV 4. After receiving the command, the control system of UAV 4 starts the corresponding operation equipment 2, such as turning on the high-definition camera and infrared thermal imager in inspection mode.

[0032] S6: Data Acquisition and Transmission: During the operation of the work equipment 2, the collected audio, video, temperature, and flaw detection data are transmitted to the drone 4 via the transmission cable 5. After being encoded by the control system, the data is transmitted back to the ground control terminal in real time via the 5G network. Based on the data display, the operator can control the drone 4 to move at a constant speed along the length of the cable, achieving continuous operation along the entire cable section. At the same time, the terminal automatically stores all data for subsequent analysis.

[0033] S7: Operation Completion and Recovery: After the operation is completed, the drone 4 is slowly raised to the preset position in S3. The pressure of the cable on the sub-frame 3 is released, and the sub-frame resets under its own weight and the action of the hinge, disengaging from the contact state with the right limit frame 12. Then, the drone 4 is controlled to move towards the left limit frame 11, and at the same time, the drone 4 is lowered, so that the cable is separated from the receiving cavity 13 from the opening structure 14. Finally, the return command is sent through the ground terminal, and the drone 4 carries the main frame 1 and the operation equipment 2 back to the designated recovery point, completing the operation process.
