Description

Technical Field

[0001] This invention relates to the field of inspection drone technology, and in particular to an intelligent power inspection drone for high-voltage overhead lines. Background Technology

[0002] In recent years, with the development of drones, the low-altitude economy has shown outstanding performance. Based on low-altitude airspace and using aircraft such as drones, electric vertical take-off and landing aircraft, and helicopters as carriers, it has become a comprehensive economic form that radiates and drives the integrated development of the entire industrial chain, including R&D and manufacturing, operation and service, airspace management, and safety assurance, through low-altitude flight activities in multiple scenarios such as carrying people, cargo and other operations.

[0003] Unmanned aerial vehicles (UAVs) are aircraft that do not require direct piloting and operate through remote control or autonomous programs. They encompass various types, including multi-rotor, fixed-wing, and vertical takeoff and landing (VTOL) aircraft, and are widely used in both civilian and military fields. In the civilian power industry, they have effectively replaced manual inspections with remarkable results.

[0004] However, traditional intelligent power inspection drones used for high-voltage overhead lines have a fixed and single battery connection method, which makes them susceptible to external interference in complex inspection work, resulting in unsuccessful inspection tasks. Summary of the Invention

[0005] This invention discloses an intelligent power inspection drone for high-voltage overhead lines, which can solve the technical problem that traditional intelligent power inspection drones for high-voltage overhead lines have a fixed and single battery connection method, are easily affected by external interference in complex inspection work, and thus lead to unsmooth inspection tasks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A smart power line inspection drone for high-voltage overhead lines includes a fuselage, a housing, and a connecting base mounted on the bottom of the fuselage. A battery box is located at the bottom of the connecting base. A wing assembly is connected to the outer wall of the fuselage. A probe mounting assembly and a fixing assembly are also located at the bottom of the connecting base. An airflow cooling assembly is located inside the battery box. The airflow cooling assembly includes two symmetrically distributed inner liner frames inside the battery box. Each inner liner frame has a hollow airflow channel inside. A common mesh plate is installed at the bottom of both inner liner frames. The battery body is located on the top of the mesh plate. Upper and lower guide holes are equidistantly distributed on both outer walls of the battery box. The upper guide holes communicate with the interior of the battery box, and the lower guide holes communicate with the interior of the airflow channels. Both ends of the airflow channels penetrate the battery box, and a mesh cover is connected to the penetration points.

[0007] By adopting the above solution, the airflow cooling component can work with the battery box to protect and dissipate heat from the drone's battery, ensuring its stability during high-altitude operations. In actual use, the drone flies against the wind at high altitude, and the airflow enters the interior of the airflow channel through the air holes on the two mesh covers in the opposite direction. As the airflow flows from the airflow channel, it pulls the airflow inside the battery box outward. In order to maintain the internal air pressure, outside air will enter the battery box through the upper guide hole set on the side to cool it down, forming a dynamic airflow circulation. Compared with the traditional completely sealed or large-area exposed battery settings, the battery box of this solution has a better protection effect and can also provide heat dissipation, ensuring the stability of the inspection process.

[0008] In a preferred embodiment, each of the two inner liner frames has equidistantly distributed protrusions and recesses on opposite sides. The recesses have oblique holes that slope downwards and communicate with the interior of the air guide channel. The fixing assembly includes a support platform at the bottom of the connecting seat. The battery box is slidably connected to the inner wall surrounded by the support platform and the connecting seat. The connecting seat has an extension channel on this inner wall, which provides air intake space for the upper guide hole. A handle is provided on one outer wall of the battery box, and two screw fasteners are provided on one outer wall of the battery box. A fixing bolt is screwed onto the inner wall of each of the two screw fasteners. Two fixing holes are provided on the top inner wall of the connecting seat, and the fixing bolts correspond to the positions of the fixing holes.

[0009] The battery box can be fixedly installed below the connector by the set fixing components. The drone used for inspection has a large battery capacity, so the battery box that needs to be fixed is also relatively large. This is to maintain the continuity of inspection. During the fixing process, the space enclosed by the connector and the bracket can limit the position of the battery box. Two fixing bolts are screwed into the fixing holes. The fixing structure is small, which makes it easy to replace the battery later. The extension channel can provide air ducts for the upper guide hole. While maintaining stable fixing, it will not cause overall heat dissipation. Combined with the structural design of the battery box, it optimizes heat dissipation.

[0010] In a preferred embodiment, the wing assembly includes four mounting bases disposed on the outer side of the fuselage. All four mounting bases are fixed to the fuselage by screws. Each mounting base has a connection hole. A fastening sleeve is connected to one side of each mounting base. An arm is mounted on the inner wall of the fastening sleeve. One end of the arm has a threaded structure. The arm is connected to a driver through the threaded structure. The output end of the driver is connected to a blade.

[0011] The modular arms allow the drone to be disassembled and packed during remote transport, and most of the fixing structures used in the assembly process are installed with screws, making the assembly process convenient.

[0012] In a preferred embodiment, the probe mounting assembly includes a sliding hole disposed on one side of the top outer wall of the connector, a mounting bracket disposed on the inner wall of the sliding hole, a screw hole disposed at the center of the bottom of the mounting bracket, a mounting rod screwed onto the inner wall of the screw hole, a bracket mounted on the bottom of the mounting rod, and a probe mounted on the inner side of the bracket.

[0013] The sliding holes improve the compatibility of installation with different probe structures. When different probe models are used for data acquisition, the mounting brackets and rods used for installation can be replaced to adapt them. During installation, they only need to be assembled into the sliding holes.

[0014] In a preferred embodiment, the inner wall of the housing is provided with a cabin, the inner wall of the cabin is provided with a partition, the bottom and top of the partition are respectively used to install control elements, the partition has symmetrically arranged vertical perforations, and the inner walls on both sides of the cabin are provided with horizontal perforations, which communicate with the connecting holes.

[0015] The wiring harness for driving the blade rotation passes through the inside of the arm, the connection hole, and the transverse through hole into the nacelle, where it connects to the control components inside the nacelle. The entire housing is fixed to the top of the fuselage by screws, and after tightening, it is kept sealed to prevent the internal components from getting damp.

[0016] As can be seen from the above, the intelligent power line inspection drone provided by this invention has the following improvements and advantages compared with the prior art: Firstly, it has good heat dissipation. The battery box of the drone is fixed and stable, and it makes full use of the airflow during the drone's flight to ensure battery heat dissipation and ensure the stability of the drone inspection process. Secondly, it has good protection. The stable battery box ensures the power structure functions properly. At the same time, the fixing bolts and fixing holes allow for quick and easy installation and removal. The top casing also ensures airtightness, preventing internal components from getting damp. Thirdly, it has strong adaptability, using sliding holes to freely match the installation of different probes, and the assembly process according to specific usage requirements is more user-friendly.

[0034] Reference Figures 1 to 16 A smart power inspection drone for high-voltage overhead lines includes a fuselage 1, a housing 2, and a connecting seat 9 installed at the bottom of the fuselage 1. A battery box 8 is provided at the bottom of the connecting seat 9. A wing assembly is connected to the outer side wall of the fuselage 1. The connecting seat 9 is characterized in that a probe 22 mounting assembly and a fixing assembly are also provided at the bottom of the connecting seat 9, and a wind-guiding heat dissipation assembly is provided inside the battery box 8. The airflow cooling assembly includes two symmetrically distributed inner liner frames 25 inside the battery box 8. Each inner liner frame 25 has a hollow airflow channel 31 inside. The bottom of the two inner liner frames 25 is equipped with the same mesh plate 26. The top of the mesh plate 26 is equipped with the battery body 24. The outer walls on both sides of the battery box 8 are provided with equally spaced upper guide holes 27 and lower guide holes 28. The upper guide holes 27 communicate with the interior of the battery box 8, and the lower guide holes 28 communicate with the interior of the airflow channel 31. The two ends of the airflow channel 31 pass through the battery box 8, and a mesh cover 23 is connected at the point of penetration.

[0035] Specifically, by adopting the above solution, the airflow cooling component can work with the battery box 8 to protect and dissipate heat from the UAV's battery body 24, ensuring its stability during high-altitude operations. In actual use, the UAV flies against the wind at high altitude, and the airflow enters the interior of the airflow channel 31 through the air holes on the two mesh covers 23 in the opposite direction. As the airflow flows from the airflow channel 31, it pulls the internal airflow of the battery box 8 outward. In order to maintain the internal air pressure, the outside air will enter the interior of the battery box 8 through the upper guide hole 27 set on the side to cool down, forming a dynamic airflow circulation. Compared with the traditional completely sealed or large-area exposed battery setup, the battery box 8 of this solution has a better protection effect and can also provide heat dissipation, ensuring the stability of the inspection process.

[0036] Among them, the mesh plate 26 is located at one-third of the overall height of the battery box 8. The raised design of the mesh plate 26, together with its own ventilated structure, can ensure that the bottom of the battery body 24 can also be fully covered during the heat dissipation process, ensuring the integrity and sufficiency of heat dissipation.

[0037] Reference Figure 12 , Figure 13 and Figure 14 In a preferred embodiment, each of the two inner liner frames 25 has equidistantly distributed protrusions and recesses on opposite sides, and the recesses have oblique holes 30 that are inclined downwards and communicate with the interior of the air guide channel 31.

[0038] It should be noted that when encountering rain, during the drone's flight, rainwater may drift into the airflow channel 31 along with the airflow. However, the battery body 24 will not come into contact with rainwater after being raised. At the same time, the airflow will bring outside air into the battery box 8 through the upper guide hole 27 on the side, and will not bring in rainwater. Occasionally, some rainwater will enter, but it will leak out through the slanted holes 30 on both sides or the mesh plate 26 at the bottom, and will not accumulate in the battery body 24 installation area, thus ensuring higher safety.

[0039] Reference Figure 9 , Figure 10 , Figure 11 and Figure 12 In a preferred embodiment, the fixing assembly includes a support platform disposed at the bottom of the connecting seat 9. The battery box 8 is slidably connected to the inner wall surrounded by the support platform and the connecting seat 9. The connecting seat 9 has an extension channel 20 on the inner wall, which provides air intake space for the upper guide hole 27. A handle 21 is provided on one outer wall of the battery box 8. Two screw fasteners are provided on one outer wall of the battery box 8. A fixing bolt 29 is screwed onto the inner wall of each of the two screw fasteners. Two fixing holes are provided on the top inner wall of the connecting seat 9, and the fixing bolts 29 correspond to the fixing holes.

[0040] In practical use, the battery box 8 can be fixedly installed under the connector 9 using the fixed components. The drone used for inspection has a large battery capacity, so the battery box 8 that needs to be fixed is also relatively large to maintain the continuity of inspection. During the fixing process, the space enclosed by the connector 9 and the support platform can limit the position of the battery box 8. The two fixing bolts 29 are screwed into the fixing holes. The fixing structure is small, which makes it easy to replace the battery later. The extension channel 20 can provide air ducts for the upper guide hole 27, which can maintain stable fixing without overall heat dissipation. Combined with the structural design of the battery box 8, it optimizes heat dissipation.

[0041] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In a preferred embodiment, the wing assembly includes four mounting seats 11 disposed on the outside of the fuselage 1. All four mounting seats 11 are fixed to the fuselage 1 by screws. The mounting seats 11 have connection holes 15. A fastening sleeve 10 is connected to one side of the mounting seat 11. An arm 3 is installed on the inner wall of the fastening sleeve 10. One end of the arm 3 has a threaded structure. The arm 3 is connected to a driver 17 through the threaded structure. The output end of the driver 17 is connected to a blade 16.

[0042] The modular arm 3 allows the drone to be disassembled and packed during remote transport. Most of the fixing structures used in the assembly process are installed by screws, making the assembly process convenient. It should be noted that...

[0043] See attached document Figure 4 All four mounting bases 11 are embedded on the outside of the fuselage 1, and the screws used for screwing the mounting bases 11 are also hidden therein, so as to keep them fixed without affecting the overall appearance of the drone.

[0044] The driver 17 is equipped with a wiring 18, and the inner wall of the arm 3 is a hollow structure. The wiring 18 passes through the arm 3 and the connection hole 15.

[0045] Reference Figure 2 , Figure 8 , Figure 9 , Figure 10 , Figure 15 and Figure 16 In a preferred embodiment, the probe 22 mounting assembly includes a sliding hole 33 disposed on one side of the top outer wall of the connector 9, a mounting bracket 34 disposed on the inner wall of the sliding hole 33, a screw hole 35 disposed at the center of the bottom of the mounting bracket 34, a mounting rod 32 screwed onto the inner wall of the screw hole 35, a bracket 7 mounted on the bottom of the mounting rod 32, and a probe 22 mounted on the inner side of the bracket 7.

[0046] Specifically, the sliding hole 33 can improve the compatibility of installation for different probe 22 structures. When different models of probe 22 are used for data acquisition, the mounting bracket 34 and mounting rod 32 used for matching installation can be replaced and adapted. During installation, they only need to be combined into the sliding hole 33.

[0047] Reference Figure 1 and Figure 3 In a preferred embodiment, the bottom of the connector 9 and the inner wall of the sliding hole 33 are provided with anti-slip pads 36, and a connector 5 is provided on one side of the connector 9.

[0048] When the mounting rod 32 is screwed onto the mounting base 34, it will press against the anti-slip pad 36 to prevent the mounting base 34 from sliding out of the sliding hole 33, thus ensuring the stability of the probe 22 installation.

[0049] It should be noted that the connector 5 is installed in the front position of the drone, and the windward direction of connector 5 is streamlined, which effectively reduces wind resistance for the lateral movement of the drone.

[0050] Reference Figure 5 , Figure 7 , Figure 8 , Figure 15 and Figure 16 In a preferred embodiment, the inner wall of the housing 2 is provided with a cabin, and the inner wall of the cabin is provided with a partition 12. The bottom and top of the partition 12 are respectively used to install control elements. The partition 12 has symmetrically arranged vertical through holes 13. The inner walls on both sides of the cabin are provided with horizontal through holes 14, which communicate with the connection holes 15. The bottom outer wall of the body 1 is provided with four bottom fixing sleeves 19. The inner walls of the four bottom fixing sleeves 19 are all equipped with support rods 6. The bottom ends of two support rods 6 are connected to the same base support 4.

[0051] It should be noted that the wiring 18 on the driver 17 used to drive the blade 16 to rotate passes through the inside of the arm 3, the connection hole 15 and the transverse through hole 14 in sequence to enter the nacelle and connect to the control components inside the nacelle. The overall housing 2 is fixed to the top of the fuselage 1 by screwing. After tightening, it is kept sealed to prevent the internal components from getting damp.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
