When the insulator is driven to adjust the test angle, the second driving device is started to drive the second transmission worm 325 to rotate, the second annular worm 325 drives the second annular worm wheel 324 to circumferentially slide in the second annular slide 323 through meshing connection, so that the insulator placement frame 2 installed in the second annular worm wheel 324 rotates axially, that is, the detection angle of the insulator changes.
Through the meshed connection of the second annular worm wheel 324 and the second transmission worm 325, the second circumferential motion assembly 306 has motion self-locking performance, when the second driving device is closed, motion cannot be transmitted to the second transmission worm 325 through the second annular worm wheel 324, the second transmission worm 325 is closed and limited to rotate in the second driving device, the state of the insulator placement frame 2 is kept stable and unchanged, namely, the test angle of the insulator is unchanged, and the test can be stably carried out.
The second ring-shaped worm wheel 324 is arranged so that the insulator can be arranged at the center of the second ring-shaped worm wheel 324 and at the center of the first ring-shaped worm wheel 309, namely, when the test angle of the insulator and the wind generating direction of the wind generating device 304 are changed, the distance between the wind generating device 304 and the insulator is not changed.
External mounting seats 326 are arranged on one of the support frames 302 and one of the support seats 321, the first transmission worm 311 and the first driving device are mounted on the external mounting seats 326 on the support frames 302, and the second transmission worm 325 and the second driving device are mounted on the external mounting seats 326 on the support seats 321.
The external mounting seat 326 is used for providing a mounting position for the first transmission worm 311, the first driving device, the second transmission worm 325 and the second driving device, and preventing the first driving device and the second driving device from being mounted on the first annular plate 307 and the second annular plate 322 to influence the motion stability of the first annular worm wheel 309 and the second annular worm wheel 324.
In this embodiment, the first driving device and the second driving device are both existing devices that can provide power, such as a power device like a motor.
The common vertical lines of the two opposite side walls of the two supports 321 and the common vertical lines of the two opposite side walls of the two illustrated support frames 302 are perpendicular to each other, and the height of the joint of the supports 321 and the second annular plate 322 is the same as the height of the center of the axial section of the first annular plate 307.
By limiting the relative positions of the two supports 321 and the two support frames 302, the circumferential motion planes of the first annular worm wheel 309 and the second annular worm wheel 324 can be formed in a relatively vertical state, and secondly, the interference of the motion of the first circumferential motion assembly 303 and the second circumferential motion assembly 306 caused by the arrangement of the positions of the supports 321 and the support frames 302 is avoided.
Since the insulator is to be located at the center of the first annular plate 307, the heights of the first annular plate 301 and the second annular plate 322 are limited so that the center of the first annular plate 307 is the same as the horizontal installation height of the second annular plate 322.
The straight lines of the axial section circle centers on the first annular plate 307 are perpendicular to the straight lines of the axial section circle centers on the second annular plate 322, and the straight lines of the axial section circles on the first annular plate 307 are horizontal straight lines.
The planes of axial motion between the first 303 and second 306 circumferential motion assemblies are defined to be perpendicular to each other by defining a perpendicular relationship between the line of axial section centers of the first 307 and second 322 annular plates.
And the axial section of the first annular plate 307 is defined as a vertical plane by defining the straight line where the center of the axial section of the first annular plate 307 is located horizontally, and the axial section of the second annular plate 322 is further defined as a horizontal plane, i.e. the mutual perpendicular relationship between the two is defined.
