DETAILED DESCRIPTION

[0016] In order to enable experts in this field to better understand the present invention, the present invention will be explained in more detail below with reference to specific embodiments and drawings.

[0017] The terms used in the present invention are those general terms that are currently widely used in the field with regard to the functions associated with the present invention. However, these terms may vary depending on the intent of those skilled in the art, precedents, or new technologies in the field. Furthermore, certain terms may be selected by the applicant, in which case their precise meaning will be described in the detailed description of the present invention. The terms used in this specification are therefore not to be understood as mere designations, but are based on the meaning of the terms and the general description of the present invention.

[0018] With reference to Fig. Figures 1 to 8 describe the present embodiment as providing an inspection device for GIS equipment, comprising: a main body mechanism 1, wherein the main body mechanism 1 comprises a mounting part 11, a drive part 12 attached inside the mounting part 11, and a support part 13 attached to the outside of the drive part 12; a movement mechanism 2, wherein the movement mechanism 2 comprises a first inspection part 21 attached to the outside of the drive part 12, a cleaning part 22 attached to the outside of the first inspection part 21, a second inspection part 23 attached to the outside of the support part 13, and a pressure part 24 attached to the outside of the second inspection part 23; The first inspection part 21 and the second inspection part 23 serve to inspect the condition of the equipment to be inspected.The drive part 12 is used to adjust the inspection position of the first inspection part 21, the support part 13 is used to adjust the inspection position of the second inspection part 23, the cleaning part 22 is used to clean the first inspection part 21 and the pressure part 24 is used to press the second inspection part 23 firmly against the device to be inspected.

[0019] When in use, the mounting part 11 is attached to the outside of the GIS device, the first inspection part 21 and the second inspection part 23 perform the inspection on the GIS device, and the drive part 12 is driven so that the drive part 12 moves the first inspection part 21 to perform the inspection over a larger area, and the drive part 12 can also move the support part 13 so that the support part 13 moves the second inspection part 23 to perform the inspection over a larger area.

[0020] Furthermore, the cleaning part 22 can clean the first inspection part 21 and the GIS device when the first inspection part 21 is moved, thus increasing the accuracy of the inspection. Additionally, after the mounting part 11 is installed on the outside of the GIS device, the pressure part 24 is driven so that it presses the second inspection part 23 against the outside of the GIS device, further increasing the accuracy of the inspection.

[0021] In an embodiment provided for in the present application, as in Fig. As shown in Figures 1 to 3, the assembly part 11 comprises a cover 111 and first suction cups 112, which are attached inside the cover 111. Several first suction cups 112 are present. After the cover 111 has been placed on the outside of the GIS device, the first suction cups 112 and the cover 111 can be firmly attached to the outside of the GIS device by the suction action of the first suction cups 112.

[0022] In an embodiment provided for in the present application, as in Fig. As shown in Figures 1 to 6, the drive part 12 comprises an electric machine 121 attached to the outside of the hood 111, a support column 122 fixedly connected inside the hood 111, a rotating shaft 123 rotatably connected inside the support column 122, a sprocket 124 fixedly connected to the outside of the rotating shaft 123, and a chain 125 appropriately attached to the outside of the sprocket 124.

[0023] As in Fig. Figure 4 shows four support columns 122, rotating shafts 123 and sprockets 124, one of the rotating shafts 123 being fixedly connected to the output shaft of the electric machine 121.

[0024] When in use, the electric machine 121 is started, causing the electric machine 121 to rotate the rotary shaft 123, which in turn rotates the sprocket 124, thereby enabling the sprocket 124 to drive the chain 125. In an embodiment provided for in the present application, as in Fig. As shown in Figures 1 to 6, the support part 13 comprises a connecting rod 131, which is fixedly connected to the outside of the chain 125; a first slide 132, which is fixedly connected to the outside of the connecting rod 131; a first rail 133, which is attached to the outside of the first slide 132; a second slide 134, which is fixedly connected to the outside of the first rail 133; a second rail 135, which is attached to the outside of the second slide 134; and a second suction cup 136, which is attached to the outside of the second rail 135. The first slide 132 is slidably connected inside the first rail 133, the second slide 134 is slidably connected inside the second rail 135, and the central axis of the first rail 133 and the central axis of the second rail 135 are perpendicular to each other.When the chain 125 moves, the chain 125 drives the first slide 132 via the connecting rod 131, so that it moves synchronously.

[0025] If the first slider 132 of the chain 125 follows in a direction parallel to the central axis of the first rail 133, the first slider 132 slides inside the first rail 133; if the first slider 132 of the chain 125 follows in a direction perpendicular to the central axis of the first rail 133, the second slider 134 slides inside the second rail 135. The arrangement of the first rail 133, the second slider 134, and the second rail 135, and the alignment of the central axes of the first rail 133 and the central axes of the second rail 135, ensures that the first slider 132 can move in all directions in the plane.

[0026] In an embodiment provided for in the present application, as in Fig. As shown in Figures 1 to 7, the first inspection part 21 comprises a connecting rod 211 fixedly connected to the outside of the chain 125, a third slide 212 fixedly connected to the outside of the connecting rod 211, a third rail 213 attached to the outside of the third slide 212, a first spring 214 and a second spring 215 attached inside the third rail 213, a disc 216 rotatably connected to the outside of the third rail 213, a base 217 fixedly connected to the outside of the disc 216, and a first sensor 218 appropriately attached to the outside of the base 217.

[0027] The third slide 212 is slidably connected inside the third rail 213; the two ends of the first spring 214 are each fixedly connected to the third slide 212 and the third rail 213; the two ends of the second spring 215 are each fixedly connected to the third slide 212 and the third rail 213. The first sensor 218 can be a temperature sensor, but can also be replaced by another sensor depending on the actual inspection requirements.

[0028] When the chain 125 moves, the chain 125 drives the third slide 212 via the connecting rod 211, so that it moves synchronously, the third slide 212 can drive the third rail 213, so that it moves synchronously, whereby the third rail 213 sets the disc 216 in motion.

[0029] During the movement of the disk 216, the first sensor 218 rolls on the outside of the base 217 upon contact of the first sensor 218 with the GIS device due to the rotatable connection between the disk 216 and the third rail 213, i.e. the disk 216 rotates, so that several first sensors 218 can alternately perform the inspection, resulting in a longer service life of the first sensors 218 and more accurate inspection results.

[0030] Furthermore, since the first inspection part 21 moves synchronously with the chain 125, the inspection can be carried out on a larger area to be inspected.

[0031] Furthermore, the first sensor 218 is raised or lowered when it passes over and crosses a protrusion or depression on the outside of the GIS device. In doing so, the first sensor 218 drives the third rail 213 for raising or lowering via the base 217 and the disc 216, utilizing the elasticity of the first spring 214 and the second spring 215 for adaptive adjustment.

[0032] In an embodiment provided for in the present application, as in Fig. As shown in Figures 1 to 7, the cleaning part 22 comprises a connecting plate 221 which is fixedly connected to the outside of the third rail 213, and a cleaning wheel 222 which is rotatably connected to the outside of the connecting plate 221.

[0033] The outer surface of the cleaning wheel 222 comes into contact with the first sensor 218, and the outer surface of the cleaning wheel 222 comes into contact with the outer surface of the GIS device.

[0034] During the movement of the first inspection part 21 with the chain 125, the connecting plate 221 drives the cleaning wheel 222 so that it moves synchronously with the third rail 213. As the cleaning wheel 222 moves, it rolls over the outer surface of the GIS device, thereby cleaning it. Since the cleaning wheel 222 is also in contact with the first sensor 218, its outer surface can also be cleaned, thus increasing the accuracy of the inspection. In an embodiment provided in the present application, as shown in Fig. As shown in Figures 1 to 8, the second inspection part 23 comprises an extension plate 231, which is fixedly connected to the outside of the first slide 132, a first U-shaped frame 232, which is fixedly connected to the outside of the extension plate 231, a cylinder 233, which is attached to the outside of the first U-shaped frame 232, a second U-shaped frame 234, which is slidably connected to the outside of the first U-shaped frame 232, a mounting bracket 235, which is slidably connected to the outside of the second U-shaped frame 234, a third spring 236, which is attached to the outside of the mounting bracket 235, a straight rod 237, which is fixedly connected to the outside of the mounting bracket 235, and a second sensor 238, which is appropriately attached to the outside of the straight rod 237.The second U-shaped frame 234 is fixedly connected to the outlet end of the cylinder 233, the two ends of the third spring 236 are each fixedly connected to the second U-shaped frame 234 and the mounting bracket 235, the second sensor 238 can be a resistive-capacitive sensor, but can also be replaced by another sensor depending on the actual inspection requirements.

[0035] After the hood 111 has been attached to the outside of the GIS device, the cylinder 233 is driven so that the output end of the cylinder 233 causes the second U-shaped frame 234 to lower, which in turn causes the second U-shaped frame 234, via the third spring 236, to lower the mounting bracket 235, which in turn causes the mounting bracket 235, via the straight rod 237, to lower the second sensor 238 until the second sensor 238 comes into contact with the GIS device.

[0036] After the second sensor 238 comes into contact with the GIS device, the first slide 132, when moved over the extension plate 231, sets the first U-shaped frame 232 in motion, causing the second sensor 238 to move synchronously and thus allowing the second sensor 238 to perform the inspection on a larger area on the outside of the GIS device.

[0037] In an embodiment provided for in the present application, as in Fig.As shown in Figures 1 to 8, the pressure element 24 comprises a first rack 241, which is slidably connected to the outside of the mounting bracket 235; a second rack 242, which is fixedly connected to the outside of the second U-shaped frame 234; a gear 243, which is rotatably connected to the outside of the straight rod 237; a first connecting rod 244, which is articulated to the outside of the first rack 241; a second connecting rod 245, which is articulated to the outside of the first connecting rod 244; and a pressure block 246, which is rotatably connected to the outside of the second connecting rod 245. The gear 243 engages with both the first rack 241 and the second rack 242, and the second connecting rod 245 is articulated to the straight rod 237.

[0038] Once the second sensor 238 comes into contact with the GIS device, the cylinder 233 is driven further, causing the output end of the cylinder 233 to lower the second U-shaped frame 234 further. Since the mounting bracket 235, the straight rod 237, and the second sensor 238 cannot be lowered any further, the third spring 236 is compressed. Furthermore, as the second U-shaped frame 234 continues to lower, it causes the second rack 242 to descend, which in turn causes the gear 243 to rotate. The rotation of the gear 243 causes the first rack 241 to rise, which in turn causes the first connecting rod 244 to rise.The articulated connection between the first rack 241, the first connecting rod 244, and the second connecting rod 245 causes the second connecting rod 245 to press the pressure block 246 downwards, thereby pressing the pressure block 246 against the second sensor 238. This ensures stable contact between the second sensor 238 and the GIS device.

[0039] In summary, the interaction of the individual components allows the first sensor 218 and the second sensor 238 to be moved over a large area. This enables inspection to be carried out over a larger area without excessively increasing the number of sensors. This improves the reliability of the inspection results.

[0040] Finally, it should be noted that the methods and devices described in detail above are merely exemplary embodiments which can be modified in various ways by those skilled in the art in this field, as long as the scope of the present invention is not exceeded.
