Obviously, the described embodiments 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.

[0029] See also Figure 1-Figure 5 The present invention provides a technical solution: a line inspection radar installation structure, including a body 110 and an analysis box 120, a positioning box 130 is fixedly installed on the top of the body 110, and a positioning groove matching the positioning box 130 is provided at the bottom of the body 110, and a slide plate 131 is symmetrically slidably installed on the inner wall of the positioning box 130, and two slide plates 131 are fixedly installed on one side away from each other, and one end of the slide block 132 slides through one side of the positioning box 130 and is inserted into the inner wall of the positioning groove, and an adjustment component is installed on the slide plate 131, and positioning plates 121 are fixedly installed on the four corners of the analysis box 120, and the positioning plates 121 are fixedly connected to the body 110 by bolts 122.

[0030] In some specific implementation schemes, the analysis box 120 is equipped with a radar system designed specifically for drone line inspections. This system integrates a single-line laser radar and a visual recognition module, and is suitable for inspections of transmission lines at voltage levels of 110kV and above. It has a wide range of functions: it can obtain uninterrupted visible light images of the conductors, helping to visually view the appearance of the conductors; uninterrupted infrared images of the conductors can detect abnormal conductor temperatures; multi-angle visible light images and infrared images of the spacers are used to accurately identify various defects in the spacers; the system can also calculate key data such as the maximum sag of the conductors and the distance between dangerous points and trees. In the entire system architecture, key components responsible for data transmission and control are specially set up to achieve efficient data interaction and processing. It uses a single-chip microcomputer with specific communication protocols and data processing capabilities. The single-chip microcomputer is electrically connected to the inspection radar through a specific circuit connection method to ensure stable and high-speed data transmission between the two. At the same time, the microcontroller uses adaptive signal transmission technology to establish a signal connection with the control host, ensuring that important information such as tree obstacle analysis data and spacer defect identification results are transmitted to the control host in a timely and accurate manner for further analysis and processing by staff. The entire radar system has been optimized and weighs less than 200g, making it easily adaptable to a variety of drone platforms. Leveraging advanced laser point cloud and visual recognition fusion technology, the system achieves stable tracking of ground wire targets, efficiently completing functions such as transmission line ground wire inspections, spacer defect identification, tree-line conflict analysis, conductor sag measurement, and conductor foreign object inspections, fully meeting the operational requirements of "increasing efficiency, saving electricity, accurate positioning, and strong expansion."

[0031] In some specific embodiments, a first thread groove matching the bolt 122 is provided at the top of the body 110. The first thread groove is provided at the four corners of the positioning box 130, which can enhance the connection stability between the analysis box 120 and the body 110 and avoid the displacement of the installation structure due to single-point force.

[0032] In some specific embodiments, guide rods 133 are symmetrically fixed between the inner walls of the positioning box 130, and the slide 131 is slidably mounted on the guide rods 133. The positioning box 130 is opened on the side closer to the housing 110. This provides guidance for the movement of the slide 131 and ensures the precise positioning of the insert 132 when it is inserted into the positioning slot. The opening on the side of the positioning box 130 closer to the housing 110 facilitates the rapid docking of the insert 132 with the positioning slot.

[0033] See also Figure 5-Figure 7The adjustment assembly includes a support frame 140 and a threaded rod 141. The support frame 140 is fixedly mounted between the top end of the inner wall of the positioning box 130 and the body 110. The threaded rod 141 is symmetrically mounted on both sides of the support frame 140 for rotation. The slide 131 and the insert 132 are threadedly mounted on the threaded rod 141. A driving assembly is mounted on one end of the threaded rod 141. The slide 131 and the insert 132 are provided with a first threaded hole and a second threaded hole that match the threaded rod 141 and are interconnected. A gap is provided between the threaded rod 141 and the inner wall of the positioning box 130, and a slot is provided on the inner wall of the positioning groove that matches the insert 132. When the threaded rod 141 rotates, it drives the slide 131 to slide through the threaded hole, thereby achieving telescopic control of the insert 132. A gap is provided between the threaded rod 141 and the inner wall of the positioning box 130 to prevent friction and jamming. The slot on the inner wall of the positioning groove matches the insert 132, which can enhance the locking strength of the installation structure. The drive assembly includes a first rotating shaft 142, a second rotating shaft 143, and an elastic telescopic rod 144. The first rotating shaft 142 is rotatably mounted between the inner walls of the support frame 140. Both ends of the first rotating shaft 142 pass through the support frame 140 and are fixedly connected to one end of the adjacent threaded rod 141. The second rotating shaft 143 is rotatably mounted between the inner wall of the positioning box 130 and the body 110. A worm 145 is fixedly mounted on the second rotating shaft 143, and a worm gear 146 is fixedly mounted on the first rotating shaft 142. The worm 145 and the worm gear 146 are in transmission connection. The elastic telescopic rod 144 is fixedly mounted on one end of the first rotating shaft 142. One end of the elastic telescopic rod 144 passes through the body 110 and is fixedly mounted on a turntable 147. Rotating the turntable 147 synchronously drives the threaded rods 141 on both sides to rotate, ensuring the synchronous movement of the slide 131. The elastic telescopic rod 144 connects the first rotating shaft 142 and the turntable 147, facilitating external control of the drive assembly.

[0034] In some specific embodiments, the elastic telescopic rod 144 includes a sleeve rod 150, a pull rod 151, and a spring 152. The sleeve rod 150 is fixedly mounted on one end of the second rotating shaft 143. One end of the sleeve rod 150 slides through the body 110 and slides onto the pull rod 151. The spring 152 is fixedly mounted between the pull rod 151 and the inner wall of the sleeve rod 150. The turntable 147 is fixedly mounted on one end of the pull rod 151. A slider 153 is symmetrically fixedly mounted on the outer side of the pull rod 151. The inner wall of the sleeve rod 150 is provided with a groove that matches the slider 153. A limiting ring is fixedly mounted on the outer side of the sleeve rod 150. An annular groove that matches the limiting ring is provided in the body 110. The pull rod 151 cooperates with the slide groove of the sleeve rod 150 through the slider 153. When the spring 152 is stretched, the turntable 147 can be driven out of the circular groove to unlock the drive assembly. The structural design takes into account both elastic reset and sliding guide functions.

[0035] In some specific embodiments, the bottom end of the housing 110 is provided with a circular groove that matches the turntable 147. A pull groove is provided on one side of the turntable 147. A pull block 148 is fixedly mounted on the inner wall of the pull groove. The pull block 148 has a T-shaped cross section, and the turntable 147 is slidably connected to the inner wall of the circular groove. Pulling the pull block 148 can easily move the turntable 147, making it easier to operate.

[0036] In some specific embodiments, a plurality of limiting bars 149 are fixedly mounted on the outside of the turntable 147. The inner wall of the circular groove is provided with strip grooves that match the limiting bars 149. The plurality of limiting bars 149 are equidistantly mounted on the outside of the turntable 147. After installation, the limiting bars 149 fit into the strip grooves, preventing the turntable 147 from rotating accidentally, ensuring that the insert 132 remains locked, and enhancing the anti-loosening performance of the mounting structure.

[0037] An embodiment of the present invention further provides a drone, comprising the above-mentioned line inspection radar installation structure and a drone body, wherein the drone body is the body.

[0038] Working Principle: To install or remove the analysis cartridge 120, first pull the pull block 148 on the turntable 147, causing the turntable 147 to drive the pull rod 151 to slide within the sleeve 150, compressing the spring 152. Simultaneously, the slider 153 slides within the slot, ensuring smooth movement of the pull rod 151. At this point, the elastic telescopic rod 144 extends, disengaging the turntable 147 from the circular slot and releasing the position limit. Rotating the turntable 147 drives the pull rod 151 and sleeve 150, which in turn rotates the worm gear 146 via the first rotating shaft 142. The worm 145, meshing with the worm gear 146, drives the second rotating shaft 143, thereby rotating the threaded rod 141. Because the slide 131 and the insert 132 are provided with first and second threaded holes that match the threaded rod 141, the rotation of the threaded rod 141 drives the slide 131 to slide on the guide rod 133, driving the insert 132 to move, allowing it to be withdrawn from or inserted into the positioning slot, thereby completing the installation or removal of the analysis box 120 from the body 110. After installation, the turntable 147 is released. Under the elastic force of the spring 152, the pull rod 151 drives the turntable 147 back to its original position. The limit bar 149 on the turntable 147 engages the strip groove on the inner wall of the circular slot, completing the fixed position. The inspection radar inside the analysis box 120 performs a simulated line inspection operation, transmitting data to the single-chip microcomputer, which then transmits the signal to the control host for analysis and processing of the inspection data.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
