Sequence of mechanical actions of the whole device:

when the equipment of the invention is operated, the motor 57 is started to rotate in a positive direction, so that the driving shaft 58 is driven to rotate, so that the bevel gear II 13 is driven to rotate, the bevel gear II 13 is in meshing transmission with the bevel gear I56, so that the rotating shaft 46 is driven to rotate, so that the mounting disc 45 provided with teeth on the lower end wall is driven to rotate, the mounting disc 45 provided with teeth on the lower end wall is in meshing transmission with the gear 43, so that the rotating disc shaft 37 is driven to rotate, so that the rotating disc 74 is driven to rotate, so that the gear lever 36 is driven to rotate, the gear lever 36 is in contact transmission with the shift lever 73, so that the shift lever shaft 75 is driven to move, so that the shift lever shaft mounting bracket 71 is driven to rotate, so that the rotating drum 70 is driven to rotate, so that the screw 64 is, the screw 64 rotates to drive the sliding block 33 to move upwards, when the sliding block 33 moves upwards to be in contact with the contact block 21, the contact block 21 moves rightwards, the wire rope one 84 is loosened, the connecting block 82 is pushed leftwards due to the action of the connecting spring two 83, the sleeve 81 moves leftwards, the bevel gear three 24 and the bevel gear four 66 are in meshing transmission, the driving shaft 58 rotates, the spline 85 rotates, the sliding shaft 80 rotates, the bevel gear three 24 and the bevel gear four 66 rotate, the bevel gear shaft 34 rotates, the mounting block 59 rotates, and the mounting block 31 rotates, thereby moving the lightning rod 29.

When the lightning rod 29 or the mounting rod 31 is damaged, the weight is lightened, so that the spring switch 69 is contracted, the ejector rod 67 is moved upwards, the mounting block 59 is driven to move upwards, and the spring switch 69 sends a signal to the motor 57.

The motor 57 receives the signal of the mounting block 59, so that the motor 57 rotates reversely, thereby rotating the driving shaft 58, thereby rotating the second wire 14, thereby tightening the second wire 14, thereby compressing the second connecting spring 83, thereby moving the connecting block 82 to the right, thereby disengaging the bevel gear four 66 from the bevel gear three 24, rotating the driving shaft 58, thereby rotating the rotating shaft 46, thereby rotating the rotary plate shaft 37, thereby rotating the lead screw 64, thereby moving the sliding block 33 downwards, thereby driving the friction block 65 to move downwards and generating electric energy by friction between the friction generating plate 25 to supply power to the electromagnet 53, when the sliding block 33 moves downwards to the extreme position, the screw rod 64 does not rotate any more, and the shift lever 36 and the shift lever 73 are in continuous contact transmission, so that the shift lever shaft 75 is driven to rotate, and the torsion spring 72 is driven to move.

The electromagnet 53 is energized to attract the attraction block 52, so that the connecting rod 54 moves to the right, so that the brake tooth 55 is disengaged from the cam cavity 47, the driving shaft 58 rotates in the reverse direction, so that the mounting plate 18 rotates, so that the engagement groove 17 rotates, the engagement transmission between the engagement groove 17 and the engagement tooth 79 drives the rotating frame 76 to rotate, so that the cam shaft 32 rotates, so that the cam 42 rotates, and the contact transmission between the cam 42 and the sliding rod 39 pushes the mounting block 59 to move to the left, so that the damaged lightning rod 29 or the mounting rod 31 is replaced, and the replaced mounting block 59 enters the collection cavity 27.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
