[0028] Accessing information and conducting routine inspections of high-altitude equipment such as GIS equipment, lightning rod counters, and density relays is difficult. Existing technology uses drones to record video, allowing cameras to be mounted on drones for remote inspections. However, this existing technology uses drones equipped with cameras for recording, which requires advanced skills to control the drone's hovering in the air and specialized training for drone operation. Furthermore, drones are expensive and difficult to maintain, resulting in high equipment procurement, operation, and maintenance costs. Drones require electricity to fly, and when the drone runs out of power, the equipment becomes unusable, creating power shortages.

[0029] In view of this, the utility model provides a ground inspection device for high-altitude equipment, with a telescopic support rod assembly as a telescopic structure, and a first reflector assembly and a second reflector assembly as a high-altitude equipment observation device, thereby realizing the inspection and information acquisition operations of the high-altitude equipment without considering power supply anxiety, and realizing efficient real-time inspection.

[0030] See also Figures 1 to 3The present invention provides a ground inspection device for high-altitude equipment, which includes a telescopic support rod assembly 100, a first boom assembly 200, a second boom assembly 300, a first reflector assembly 400, a second reflector assembly 500, and an optical enhancement device 600. The telescopic support rod assembly 100 uses a telescopic rod, one end of which is installed on the ground and the other end extends upward. The first boom assembly 200 and the second boom assembly 300 are installed on the telescopic support rod assembly 100, and the first boom assembly 200 is located on the telescopic rod body of the telescopic support rod assembly 100. As the telescopic support rod assembly 100 is extended or retracted, the equipment is lifted or lowered. The second boom assembly 300 is installed below the first boom assembly 200 and is located on the non-telescopic rod body of the telescopic support rod assembly 100. The first boom assembly 200 and the second boom assembly 300 are used to install the first reflector assembly 400 and the second reflector assembly 500, respectively. The first reflector assembly 400, through the telescopic movement of the telescopic support rod assembly 100, is positioned corresponding to the overhead equipment to receive and reflect light from the overhead equipment. The second reflector assembly 500, serving as an observation mirror, is located at the bottom of the telescopic support rod assembly 100. Its installation position on the second boom assembly 300 corresponds to the position of the first reflector assembly 400 to receive light from the overhead equipment reflected by the first reflector assembly 400. The optical enhancement device 600 is used to magnify and observe the image of the overhead equipment reflected by the second reflector assembly 500, ensuring accurate acquisition of images and data information of the equipment to be inspected. No electrical equipment is used, so there is no need to worry about power supply issues.

[0031] In an example of a ground inspection device of the present invention, the first boom assembly 200 includes a first boom connector 210 and a first boom 220.

A first reflector assembly 400 is mounted on the first boom 220. In this embodiment, the first boom connector 210 adopts a cross fastener, i.e., a right-angle fastener, and the first boom 220 adopts a circular tube.

The relative positions of the first boom 220, the first reflector mounting bracket 410, and the telescopic support rod assembly 100 minimize the space occupied by the upper portion of the ground inspection device, thereby avoiding excessive space occupation at the upper portion and interference with high-altitude equipment, thereby causing inspection obstacles. The first reflector 420 is rotatably mounted at the end of the first reflector mounting bracket 410 away from the first boom 220. By rotating the first reflector 420 to adjust the angle of the first reflector 420, the first reflector 420 is ensured to receive light from the high-altitude equipment and reflect it to the second reflector assembly 500. Specifically, the first reflector mounting frame 410 includes a support rod connector 411, a first reflector support rod 412, and a rotating clamping assembly 413. The first reflector support rod 412 is fixedly connected to the first suspension rod 220 via the support rod connector 411. The rotating clamping assembly 413 is rotatably mounted on the lower portion of the first reflector support rod 412 and clamps and connects the first reflector 420. The rotation of the rotating clamping assembly 413 drives the clamped first reflector 420 to achieve angle adjustment. In this embodiment, the support rod connector 411 uses a cross fastener, through which the first reflector support rod 412 is vertically mounted to the lower portion of the first suspension rod 220. The rotating clamping assembly 413 uses spherical mica and a flat plate fixing clamp. The first reflector 420 is a plane mirror. The rotation mechanism of the spherical mica and the clamping of the plane mirror by the flat plate fixing clamp realize the rotational clamping function of the first reflector 420. The cross fastener, spherical mica and flat plate fixing clip in this embodiment can be obtained through general commercial means, and their functions and structures are well known in the industry. Therefore, their essential contents will not be described in detail here.

[0034] In an example of the ground inspection device of the present invention, the second reflector assembly 500 is used to receive the light reflected by the first reflector 420 from the high-altitude equipment, so as to enable ground personnel to obtain information. The structure of the second reflector assembly 500 is consistent with that of the first reflector assembly 400. Specifically, the second reflector assembly 500 includes a second reflector mounting bracket 510 and a second reflector 520. The second reflector mounting bracket 510 is fixedly mounted on the upper part of the second boom 320 and is parallel to the telescopic support rod assembly 100. The second reflector 520 is rotatably mounted on the upper end of the second reflector mounting bracket 510 away from the second boom 320; the reflecting surface of the second reflector 520 is arranged relatively parallel to the reflecting surface of the first reflector 420, and the reflecting surface of the first reflector 420 is away from the direction of the telescopic support rod assembly 100 and faces the direction of the high-altitude equipment; the reflecting surface of the second reflector 520 is facing the direction of the telescopic support rod assembly 100, so as to intuitively convey the reflected image to the inspection personnel.

[0035] See also Figure 3 In an example of the ground inspection device of the present invention, in order to prevent the risk of falling objects from being bumped and broken when the first reflector 420 is observed at a high place, the first reflector assembly 400 preferably includes an explosion-proof assembly 430. The explosion-proof assembly 430 is adhesively connected to the non-reflective surface of the first reflector 420 and fixedly connected to the upper part of the ground inspection device; specifically, the explosion-proof assembly 430 includes an explosion-proof sticker 431, an explosion-proof pull ring 432 and an anti-fall rope 433. The explosion-proof sticker 431 is a wall sticker or wallpaper with self-adhesion and certain tear resistance.

The anti-fall rope 433 is also tied to the upper part of the ground inspection device, such as the first boom 220, the first reflector mounting frame 410 or the top of the telescopic support rod assembly 100. When the first reflector 420 is broken, the rotating clamping assembly 413 loses its grip on the first reflector 420, and the broken first reflector 420 falls freely. The explosion-proof ring 432 is pulled by the anti-fall rope 433, and the explosion-proof ring 432 is bonded to the explosion-proof sticker 431 to prevent fragments of the first reflector 420 from falling. The wall sticker and mobile phone finger ring buckle in this embodiment can be obtained through general commercial means. Their functions and structures are well known in the industry.
