Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a power grid inspection and wiring UAV. Background Technology

[0002] As an innovative application in the power industry, drone-based power line erection technology not only improves the efficiency and safety of power line construction but also reduces labor and material costs. With continuous technological advancements, drones will be increasingly widely used in power line erection, inspection, and maintenance, and may become one of the standard tools for power companies' daily operations and maintenance.

[0003] Problems with existing technology:

[0004] Existing drones typically use lightweight tethers when laying power lines. One end of the tether is pulled from one power tower to another, and then the cable is connected between the two towers by pulling a thicker rope with a thinner rope. This process avoids contact with trees, roads, and rivers below, thus increasing work efficiency. However, the drone is always operating at high altitude during this process. When the tether extends to a certain length, crosswinds are prone to occur at high altitudes. The longer the tether, the greater the impact of the wind. The spool and the drone's pulling rope at both ends need to be stabilized. Under the influence of crosswinds, the drone may be pulled off the planned route by the tether, reducing work efficiency and making it difficult to control. Utility Model Content

[0005] The purpose of this invention is to provide a power grid inspection and wiring drone. Through the design of the wind-driven drag component and the lateral booster, the drone can obtain the strength of the crosswind when encountering crosswinds at high altitudes, thereby providing a counterforce to overcome the crosswind pull and enabling the drone to fly stably. Through the design of the rope release ring and the line release wheel, the drone can release the tether rope through the wind-resistant rope when encountering strong gusts, converting part of the tether rope's tension into acceleration, quickly reducing the strong pull of the gusts on the drone in a short period of time, and making the drone's flight more stable.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A power grid inspection and wiring drone includes: a wire spool, with a tether rope wound around the outside of the wire spool, and an unmanned aircraft connected to the end of the tether rope;

[0008] The unmanned aerial vehicle includes a fuselage with wings on its outer side. Lateral thrusters are fixedly installed at both ends of the fuselage. A reel is located at the bottom of the fuselage, and a wind-resistant rope is wound around the outer side of the reel. A wind-powered drag system is located on one side of the fuselage corresponding to the reel. A sliding pod is located at the bottom of the wind-powered drag system. A guide ring is fixedly connected between the reel and the sliding pod, and the wind-resistant rope extends through the guide ring to the sliding pod.

[0009] The wind power drag assembly includes a drag rod, the tops of both ends of which are fixedly connected to the machine body, and rope release rings are fixedly connected to the drag rod near both ends.

[0010] A guide column is fixedly connected to one side of the variable drag rod. The sliding chamber is sleeved on the outside of the variable drag rod and the guide column and is slidably installed. Wind-resistant springs are provided at both ends of the guide column corresponding to the sliding chamber. The two ends of the wind-resistant springs are fixedly connected to the end of the variable drag rod and the sliding chamber, respectively.

[0011] Both the wind-resistant rope and the traction rope are fixedly connected to the ends with buckles, and the wind-resistant rope and the traction rope are connected by buckles.

[0012] A camera is installed on the outside of the machine body, and a support leg is fixedly installed on the bottom of the machine body.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention, through the design of wind-driven drag components and lateral boosters, enables unmanned aerial vehicles (UAVs) to obtain crosswind strength when encountering crosswinds at high altitudes, thereby providing a counterforce to overcome crosswind pull and allowing the UAVs to fly smoothly.

[0015] This invention, through the design of the rope release ring and the line release reel, enables the unmanned aerial vehicle (UAV) to release the tether cable through the wind-resistant rope when encountering strong gusts of wind. This allows a portion of the tension in the tether cable to be converted into acceleration, quickly reducing the strong pulling force of the gusts on the UAV in a short period of time, and making the UAV's flight more stable.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1 - Figure 2 As shown, a power grid inspection and wiring drone includes: a wire reel 1, with a tether rope 3 wound around the outside of the wire reel 1, and an unmanned aircraft 2 connected to the end of the tether rope 3; a camera 203 is installed on the outside of the body 201, and outriggers 205 are fixedly installed on the bottom of the body 201.

[0025] In the process of stringing up power lines, the wire reel 1 is first fixed to the first power tower or power station, then the tow rope 3 is connected to the drone 2, and then the wire reel 1 is released to take the drone 2 to another power tower. The camera 203 is used for real-time photo detection and can be used for inspection, and the outriggers 205 are used for landing support.

[0026] See attached document Figure 3 - Figure 5The unmanned aerial vehicle (UAV) 2 includes a fuselage 201, with wings 202 mounted on the outer side of the fuselage 201. Lateral thrusters 204 are fixedly mounted at both ends of the fuselage 201. A wire reel 209 is located at the bottom of the fuselage 201. A wind-driven drag assembly 210 is located on one side of the fuselage 201 corresponding to the wire reel 209. A sliding nacelle 208 is located at the bottom of the wind-driven drag assembly 210. A wire loop 207 is fixedly connected between the fuselage 201 and the wire reel 209 and the sliding nacelle 208. A wind-resistant rope 206 passes through the wire loop. The ring 207 extends to the sliding nacelle 208; the wind-powered variable drag assembly 210 includes a variable drag rod 211, the tops of both ends of the variable drag rod 211 are fixedly connected to the body 201; a guide column 214 is fixedly connected to one side of the variable drag rod 211, the sliding nacelle 208 is sleeved on the outside of the variable drag rod 211 and the guide column 214 and is slidably installed, and wind-resistant springs 212 are provided at both ends of the guide column 214 corresponding to the sliding nacelle 208, and the two ends of the wind-resistant springs 212 are fixedly connected to the end of the variable drag rod 211 and the sliding nacelle 208 respectively.

[0027] According to the above structure, when the UAV encounters crosswinds at high altitude, the crosswinds cause the tether cable 3 to bend under stress. The coil 1 and the UAV 2 pull on both ends of the tether cable 3 to stabilize it. At the same time, the tether cable 3 pulls the coil 1 and the UAV 2 laterally. Under the pull of the tether cable 3, the UAV 2 experiences a lateral force, and the tether cable 3 pushes the sliding cabin 208 to slide laterally. At this time, the wind-resistant springs 212 on both sides push the sliding cabin 208 on one side and pull the sliding cabin 208 on the other side, thus counteracting the tension of the tether cable 3. The sliding cabin 208 is divided into two sections, and the two sections of the sliding cabin 208 are connected in series with the variable drag rod 211 and the two lateral boosters 204, forming two circuits with opposite current directions. This causes the rotation direction of the lateral boosters 204 to be affected by the crosswinds blowing from both sides. Conversely, both can provide power to counteract crosswinds; the resistance at the middle position of the sliding cabin 208 is the greatest and can be regarded as an open circuit, and the resistance is smaller the closer to the end of its two ends. This makes the total resistance in the series circuit of the sliding cabin 208 smaller as it is closer to the end under the action of the tether cable 3, and the output power of the lateral booster 204 is greater. When the tether cable 3 is subjected to crosswinds, it will drive the sliding cabin 208 to slide on the variable drag rod 211. The guide column 214 increases the elastic force to overcome the tension of the tether cable 3 according to the increase of spring deformation. The sliding cabin 208, one side of the variable drag rod 211 and the lateral booster 204 form a circuit. The total resistance is affected by the wind force. The greater the wind force, the smaller the total resistance in the circuit, the greater the current, and the greater the lateral output of the lateral booster 204, thereby overcoming the tension of the tether cable 3 and enabling the unmanned aircraft 2 to fly stably.

[0028] See attached document Figure 3 - Figure 5The outer side of the line reel 209 is wound with a wind-resistant rope 206. The variable resistance rod 211 is fixedly connected to the rope rings 213 near both ends. Both the ends of the wind-resistant rope 206 and the traction rope 3 are fixedly connected with buckles. The wind-resistant rope 206 and the traction rope 3 are connected by buckles.

[0029] According to the above structure, when encountering a strong gust of wind, the sliding cabin 208 slides to the rope release ring 213. At this time, the UAV 2 can no longer overcome the tension of the tethering cable 3 by its own power. When the sliding cabin 208 contacts the rope release ring 213, the sliding cabin 208, the rope release ring 213, and the line release reel 209 are connected in series to form a passage. One end of the line release reel 209 is equipped with a motor to drive the internal rotation of the line release reel 209 to release the wind-resistant rope 206. Under the influence of crosswinds, the tethering cable 3 pulls on the UAV 2. At this time, the UAV 2 quickly releases the wind-resistant rope 206, and the tethering cable 3 loses part of the tension on the UAV 2. At this time, part of the thrust of the crosswind on the tethering cable 3 is released. The acceleration of the tether 3 is converted into that of the tether rope 3, thereby reducing the tension on the drone 2. The tether rope 3 quickly flies to the side where the wind is blowing. After the gust ends, the sliding cabin 208 separates from the rope release ring 213. At this time, the wind-resistant rope 206 is quickly wound up. Although the recovery will change the direction of movement of the tether rope 3 and requires the drone 2 to provide tension, the gust stops at this time, so the winding can be wound up relatively stably. This method mainly converts the sudden tension generated by the gust into a relatively gentle long-term tension, so that the drone can maintain stability. When the second power tower is reached, the tether rope 3 can also be lowered to the hands of the staff by lowering the wind-resistant rope 206, so that the tether rope 3 can be removed from the drone 2.

[0030] The working principle of this utility model is as follows: When stringing lines, the wire reel 1 is first fixed to the first power tower or power station, and then the tethering rope 3 is connected to the drone 2. Then, the wire reel 1 is released to take the drone 2 to another power tower. When the drone encounters crosswinds at high altitude, the crosswinds cause the tethering rope 3 to bend under force. The wire reel 1 and the drone 2 pull the two ends of the tethering rope 3 to make it stable. At the same time, the tethering rope 3 pulls the wire reel 1 and the drone 2 laterally. Under the pull of the tethering rope 3, the drone 2 is subjected to a lateral force. The tethering rope 3 pushes the sliding cabin 208 to slide laterally. At this time, the wind-resistant springs 212 on both sides push the sliding cabin 208 on one side and pull the sliding cabin 208 on the other side, thus counteracting the tension of the tethering rope 3.

[0031] The resistance at the middle position of the sliding cabin 208 is the highest and can be considered an open circuit. The resistance decreases as the two ends approach the end. This makes the total resistance in the series circuit of the sliding cabin 208 smaller as it approaches the end under the action of the tether cable 3, and the output power of the lateral booster 204 is greater. When the tether cable 3 is affected by crosswinds, it will drive the sliding cabin 208 to slide on the variable drag rod 211. The guide column 214 increases the elastic force to overcome the tension of the tether cable 3 according to the increase of spring deformation. The sliding cabin 208, one side of the variable drag rod 211, and the lateral booster 204 form a circuit. The total resistance is affected by the wind force. The greater the wind force, the smaller the total resistance in the circuit, the greater the current, and the greater the lateral output of the lateral booster 204, thereby overcoming the tension of the tether cable 3 and enabling the unmanned aircraft 2 to fly stably.
