[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-Figure 3 The present invention shows an internal grinding device for a GIS high-voltage switch housing, comprising a grinding support housing 1, a grinding mechanism 2 being installed on the top of the grinding support housing 1, the grinding mechanism 2 comprising a telescopic member 201 fixedly connected to the top of the grinding support housing 1, a sliding groove 207 being provided on the output end of the telescopic member 201, a support arm 202 being slidably connected in the sliding groove 207, a through hole 208 being provided on the side of the sliding groove 207, a driving member 205 being fixedly connected to the output end of the telescopic member 201 and corresponding to the through hole 208, a driving gear 206 being fixedly connected to the output end of the driving member 205, teeth being provided on the support arm 202, and the driving gear 206 being connected to the support arm 202 through the through hole 208. The teeth set on the arm 202 are meshed with each other, and the support arm 202 is fixedly connected to the driving member 203, and the output end of the driving member 203 is fixedly connected to the grinding roller 204. The telescopic member 201 drives the support arm 202 to enter the high-voltage switch housing, and the driving member 1 205 drives the driving gear 206 to rotate, and the driving gear 206 drives the support arm 202 to move along the sliding groove 207. The support arm 202 drives the grinding roller 204 to approach the inner wall of the high-voltage support housing. After the grinding roller 204 is in contact with the inner wall of the high-voltage support housing, the driving member 1 205 stops moving, and the driving member 203 moves to drive the grinding roller 204 to rotate, thereby grinding the inner wall of the high-voltage support housing.

[0027] A rotating mechanism 4 is provided at the bottom of the polishing support shell 1. The rotating mechanism 4 includes a rotating base 401. The rotating base 401 is rotatably connected to the bottom of the polishing support shell 1. The rotating base 401 is fixed to the output end of the driving member 3 402. The driving member 3 402 is fixedly installed on the bottom of the polishing support shell 1. When the driving member 3 402 moves, it drives the rotating base 401 to rotate.

[0028] A clamping mechanism 3 is provided on the rotating base 401 , and the clamping mechanism 3 is used to fix the high-voltage switch housing.

[0029] When the high-voltage switch housing needs to be polished, the high-voltage switch housing is placed on the clamping mechanism 3 so that the clamping mechanism 3 fixes the high-voltage switch housing. The action of the driving member 3 402 will drive the rotating base 401 to rotate synchronously. The rotation of the rotating base 401 will drive the clamping mechanism 3 to rotate synchronously, so that the high-voltage switch housing rotates. The rotation of the high-voltage switch housing can make the polishing more efficient and the polishing effect better, thereby improving the polishing efficiency and quality.

[0030] After the high-voltage switch housing starts to rotate, the output end of the telescopic part 201 of the grinding mechanism 2 extends out, driving the grinding roller 204 to enter the interior of the high-voltage switch housing. After the grinding roller 204 enters the interior of the high-voltage switch housing, the driving part 1 205 moves, driving the support arm 202 to move, so that the grinding roller 204 can fit the inner wall of the high-voltage switch housing. After the grinding roller 204 fits the inner wall of the high-voltage hanging housing, the driving part 1 205 stops moving, and the driving part 2 203 starts moving, driving the grinding roller 204 to rotate and grind the inner wall of the high-voltage switch housing. Under the joint action of the grinding mechanism 2 and the rotation of the high-voltage switch housing, the applicability of the grinding device inside the high-voltage switch housing is effectively improved, and the efficiency during grinding is effectively improved.

[0031] Second implementation method:

[0032] Figure 4-Figure 6 The present invention shows an internal grinding device for a GIS high-voltage switch housing. Different from the first embodiment, the clamping mechanism 3 includes a clamping slide 301, which is fixedly connected to a rotating base 401. A clamping slider 302 is slidably connected to the side of the clamping slide 301. The clamping slider 302 moves along the clamping slide 301 to fix the high-voltage switch housing. The rotation of the rotating base 401 will drive the clamping mechanism 3 to rotate; a limiting column 305 is fixedly connected to the clamping slider 302, and a limiting disk 306 is fixedly connected to the bottom of the clamping slide 301. The limiting disk 306 is rotatably connected to a driving gear disk 307 through a rotating shaft 310. A limiting groove 308 is provided on the limiting disk 306, and a driving sliding groove 308 is provided on the driving gear disk 307. Slot 309, the limiting column 305 is slidably connected with the limiting slide 308 and the driving slide 309 respectively, the driving toothed disc 307 is engaged with the driving gear 304, the driving gear 304 is installed on the output end of the driving member four 303, the driving member four 303 is fixedly installed with the clamping slide 301, and a plurality of clamping sliders 302 are provided. The plurality of clamping sliders 302 are evenly distributed along the circumference of the clamping slider 302, the limiting disc 306 is provided with a plurality of limiting slides 308 corresponding to the limiting columns 305 respectively, and the driving toothed disc 307 is provided with a plurality of driving slides 309 corresponding to the limiting columns 305 respectively. When fixing the high-voltage switch housing, the traditional fixing method is time-consuming and labor-intensive, which affects the efficiency of polishing the inside of the high-voltage switch housing.

[0033] When the high-voltage switch housing needs to be fixed, the driving member 303 moves to drive the active gear 304 to rotate, and the rotation of the active gear 304 drives the driving toothed disc 307 to rotate. The rotation of the driving toothed disc 307 drives the limiting column 305 to move along the limiting slide groove 308. The movement of the limiting column 305 drives the clamping slider 302 to move. Multiple clamping sliders 302 move along the radial direction of the limiting disc 306 to fix the high-voltage switch housing. Using multiple clamping sliders 302 to fix the high-voltage switch housing can effectively improve the stability of the fixed high-voltage switch housing. At the same time, using the limiting disc 306 and the driving toothed disc 307 to drive the clamping slider 302 has a certain self-locking function, which can further improve the stability of the fixed high-voltage switch housing.

[0034] In addition, the clamping slider 302 is driven by the driving member 303 to rotate the driving gear disc 307, which can maintain the consistency of the movement of the clamping slider 302, thereby improving the fixing efficiency. There is no need for manual fixing, so that the high-voltage switch housing can be located in the center of the clamping mechanism 3 when fixed. When the high-voltage switch housing is rotated, the grinding effect will not be poor due to the shift of the center of gravity.

[0035] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
