[0045] In the utility model, the working steps of the device are as follows:

[0046] First, you can connect to the mains or install a battery of your own choice to power the entire device, then place the base plate 2 on the external measuring platform, and use the fixing bolts 3 to fix the base plate 2 to the external measuring platform. Then, according to the terrain conditions, rotate the connecting frame 6 to make the screw 13 and the spherical shaft 9 rotate synchronously. After the bubble in the bubble level 7 is located in the middle position, that is, the measuring instrument 8 is in a horizontal state, stop rotating the connecting frame 6, and use the controller 5 to start the motor 4 so that the output ends of the two groups of motors 4 rotate at the same time. The motor 4 is a stepping motor with strong controllability and sensitive response. The output end of the motor 4 drives the bidirectional screw 10 to rotate, and the two groups of bidirectional screws 10 drive the two groups of movable plates 11 to move synchronously in the center, and the two groups of clamping columns 12 move in the center accordingly, until the two groups of clamping columns 12 are tightly clamped on both sides of the outer wall of the spherical shaft 9, so that the spherical shaft 9 can no longer rotate.

[0047] When it is necessary to adjust the lateral angle of the measuring instrument 8, the limiting assembly 17 can be used to rotate the second toothed disc 16 along the middle of the connecting frame 6. The second toothed disc 16 drives the measuring instrument 8 to rotate to a suitable angle and then stops rotating. Then the screw sleeve 14 is rotated to make the screw sleeve 14 rise along the outer surface thread of the screw rod 13. The screw sleeve 14 pushes the first toothed disc 15 to rise synchronously until the top of the first toothed disc 15 is meshed with the bottom of the second toothed disc 16 to complete the fixing of the angle of the measuring instrument 8. Finally, the measuring instrument 8 is used to measure the sag of the overhead wires of the transmission line. This is an existing mature technology and will not be elaborated on here.
