Referring to fig. 1, in one embodiment, a test device for a mobile switching closet includes a carrier 100 and a stationary contact tester 200. The carrying mechanism 100 includes a bracket 110 and a base 120. The support 110 is slidably fitted on the base 120, and the support 110 is provided with a mounting plate 111. The mounting plate 111 is provided with a plurality of contact arm bases 112. The contact arm base 112 can adjust the fixed position on the mounting plate 111. One end of the static contact tester 200 is detachably connected with the contact arm base 112, and the other end of the static contact tester 200 is provided with a test hole 230. The inspection hole 230 is provided therein with a camera 210. The camera 210 is used for acquiring the position image information of the fixed contact on the switch cabinet.
The inspection device for a withdrawable switchgear comprises a carrier 100 and a stationary contact inspection body 200. The carrying mechanism 100 includes a bracket 110 and a base 120. The support 110 can slide on the base 120, so that the inspection device can conveniently approach the fixed contact of the switch cabinet slowly, and the fixed contact of the switch cabinet is prevented from being damaged. The support 110 is provided with a mounting plate 111, the mounting plate 111 is provided with a contact arm base 112, and the contact arm base 112 can adjust the fixed position on the mounting plate 111. The position of the contact arm base 112 can be guaranteed to be consistent with the position arrangement of the standard sample points 510 on the verification plate 500 by adjusting the fixed position of the contact arm base 112, so that the verification precision of the verification device is improved. One end of the static contact checking body 200 is provided with a checking hole 230, and a camera 210 is arranged in the checking hole 230. It can be seen that the distance between the static contact tester 200 and the static contact on the switch cabinet can be monitored by the camera 210 at any time, so that the static contact on the switch cabinet is prevented from being damaged due to excessive pushing. Meanwhile, the position relationship between the fixed contact on the switch cabinet and the fixed contact inspection body 200 is compared by the camera 210, so that the position of the fixed contact of the switch cabinet can be conveniently and accurately detected.
Further, one end of the stationary contact inspection body 200 is disposed coaxially with the contact arm base 112. Therefore, in the inspection process, the deviation condition of the position of the static contact on the switch cabinet and the design position can be judged only according to the deviation of the axis of the static contact inspection body 200 and the position of the static contact on the switch cabinet, so that the inspection process becomes more convenient and quick, and the inspection result of the detection device on the static contact is more accurate and more reliable.
Furthermore, the static contact test body 200 and the contact arm base 112 are hollow, which is beneficial to reducing the weight of the static contact test body 200 and the contact arm base 112, thereby facilitating the test of the static contact on the switch cabinet.
Referring to fig. 2, in one embodiment, the end of the stationary contact inspection body 200 having the inspection hole 230 is provided with the aiming tab 220. The aiming plate 220 is provided with equidistant grids. In this way, the position deviation between the fixed contact and the fixed contact inspection body 200, that is, the installation deviation of the fixed contact on the switch cabinet, can be accurately read according to the equidistant grid on the aiming plate 220. The fixed contacts with different deviations are classified by quantifying the installation deviation of the fixed contacts on each switch cabinet, so that the corresponding processing method is adopted, the classification processing of the switch cabinets is facilitated, and the working efficiency is improved.
Further, the aiming block 220 is disposed coaxially with the inspection hole 230, and the camera 210 is disposed coaxially with the inspection hole 230. Therefore, the position deviation of the fixed contact can be accurately read only by comparing the deviation of the axis of the fixed contact and the axis of the sighting piece. Therefore, the inspection device can more conveniently and rapidly read the position deviation data between the fixed contact and the fixed contact inspection body 200.
Referring to fig. 2 and 5, in one embodiment, an outer wall of an end of the contact arm base 112 remote from the mounting plate 111 is provided with a first thread 1122. One end of the stationary contact inspection body 200 is provided with a limiting hole 240. The inner wall of the limiting hole 240 is provided with a second thread 250. The first threads 1122 mate with the second threads 250. A limiting hole 240 is provided at one end of the stationary contact inspection body 200, for the purpose of ensuring that the other ends of the plurality of stationary contact inspection bodies 200 mounted on the contact arm base 112 are all in a plane, thereby enabling the stationary contact inspection body 200 to be simultaneously contacted with the stationary contact of the switch cabinet.
Referring to fig. 3 and 4, in one embodiment, the inspection apparatus for a withdrawable switchgear further includes a moving contact inspection body 300. One end of the movable contact check body 300 is detachably connected with the contact arm base 112, and the other end of the movable contact check body 300 is matched with the standard sample point 510 on the check plate 500. As can be seen from this, the movable contact test body 300 is mounted on the contact arm base 112. The contact arm base 112 is adjusted to enable the moving contact detector 300 to be identical, so that the correction of the position of the contact arm base 112 can be guaranteed to be completed rapidly and accurately, the inspection precision of the inspection device is improved, and the reliability of the inspection result of the position of the fixed contact is further improved.
Further, a connecting hole 1123 is provided at an end of the contact arm base 112 remote from the mounting plate 111. The inner wall of the connecting hole 1123 is provided with a third thread 1124. One end of the moving contact inspection body 300 is provided with a limiting convex part 310, and the outer wall of the limiting convex part 310 is provided with a fourth thread 320. The third threads 1124 mate with the fourth threads 320. A limit protrusion 310 is provided at one end of the moving contact testing body 300 in order to limit the depth of screwing the moving contact testing body 300 into the contact arm base 112. In this way, the other ends of the plurality of fixed contact check bodies 300 can be guaranteed to be on a vertical plane, so that when the fixed position of the contact arm base 112 is corrected, the other ends of the contact check bodies 300 are simultaneously contacted with the standard sample points 510 on the verification plate 500, and the fixed position of the contact arm base 112 can be accurately corrected. In addition, since the limit protrusion 310 is disposed at one end of the moving contact testing body 300, the moving contact testing body 300 can be rotated until it cannot be rotated in the assembly process, thereby greatly facilitating the installation of the moving contact testing body 300.
Specifically, one end of the moving contact testing body 300 is designed to be a "cone", and the moving contact testing body 300 and the limit projection 310 are coaxially connected.
In one embodiment, a plurality of bar-shaped holes 1111 are provided in the mounting plate 111. One end of the contact arm base 112 is provided with a plurality of mounting holes 1121, and the contact arm base 112 is connected with the mounting plate 111 by bolts passing through the bar-shaped hole slots 1111 and the mounting holes 1121. In this way, the fixed position of the contact arm base 112 can be moved by the bolt moving in the bar-shaped hole groove 1111. Thus, it is advantageous to adjust the fixed position of the contact arm base 112 on the mounting plate 111.
In another embodiment, a plurality of mounting holes 1121 are also provided on the mounting plate 111, such that the fixed position of the contact arm base 112 is adjustable by being fixed to different mounting holes 1121.
In one embodiment, the inspection device for a withdrawable switchgear also includes a sliding mechanism 400. The bracket 110 is slidably coupled to the base 120 by a sliding mechanism 400. The base 120 is provided with a verification platform 121. The verification platform 121 is used to secure the verification plate 500.
Further, the sliding mechanism 400 includes a sliding plate 420, a pulley 410, and a transmission rod 430. The pulley 410 is mounted on a sled 420. The slide plate 420 is slidable on the base 120 through the pulley 410. A support rod 122 is provided on an end of the base 120 remote from the verification platform 121. The support rod 122 is provided with a first transmission hole 1221. The transmission rod 430 is rotatably connected to the support rod 122 through the first transmission hole 1221. The slide plate 420 is provided with a second transmission hole 421 corresponding to the first transmission hole 1221 at one end near the support rod 122. The inner wall of the second transmission hole 421 is provided with a fifth thread. The outer wall of the transfer rod 430 is provided with a sixth thread 431. The sixth thread 431 is matched to said fifth thread. Therefore, the sliding plate 420 slides on the base 120 by rotating the transmission rod 430, so that the bracket 110 is driven to make the static contact check body 200 approach to the static contact on the switch cabinet. The screw driving mode can make the support 110 move slightly. Thus, the static contact on the switch cabinet can be prevented from being damaged due to the fact that the static contact test body 200 is pushed in too much when approaching the static contact on the switch cabinet.
In one embodiment, the inspection apparatus for a mobile switchgear also includes a video device 600 and a guide 113. The video device 600 is electrically connected to the camera 210. The guide 113 is mounted on the bracket 110, and a guide groove 1131 is provided on the guide 113. The guide channel 1131 is adapted to mate with a guide on the switchgear. Thereby, the movement stability of the bracket 110 in the switch cabinet can be ensured, which is beneficial to ensuring the stability of the inspection performance of the inspection device.

and step S30, acquiring static contact image information through the camera 210, and judging the position deviation degree of the static contact of the switch cabinet.
The contact arm base 112 is adjusted to a preset position so that the contact arm base 112 is arranged in a consistent manner with the standard sample point 510 on the verification plate 500. By installing the stationary contact inspection body 200, the holder 110 is slowly pushed so that the stationary contact inspection body 200 collides with the stationary contact. Then, the position relation between the static contact test body 200 and the static contact is observed through the camera 210, so that the position deviation degree of the static contact of the switch cabinet can be conveniently and accurately judged.
Further, the moving contact tester 300 is mounted on the contact arm base 112 before the contact arm base 112 is adjusted to a predetermined position. The holder 110 is pushed so that the moving contact check body 300 is in contact with the check plate 500. The contact arm base 112 is adjusted so that the contact check body 300 coincides with the standard sample point 510 on the check plate 500, and the contact arm base 112 is fixed to the mounting plate 111.
