The floating plug mechanism 2 further comprises a sliding block 14 and a sliding rail 15, wherein the sliding block 14 is connected to the folding arm structure 11, and the sliding rail 15 is connected to the upper frame 100, so that the folding arm structure 11 moves along the sliding rail 15 through the sliding block 14 to realize the contraction or/and expansion action of the folding arm structure 11. Each support rod 13 is also sleeved with a compression spring 16. The electrical plug 111 is provided on the precision guide shaft 17, and the connection of the power source and the signal transmission line can be achieved by connecting the electrical plug 111 and the receptacle in the floating receptacle mechanism 2.
Preferably, the floating socket mechanism 2 includes: a positioning plate 21, a supporting base 28 and a socket mechanism 29, wherein the positioning plate 21 is connected to the container spreader 101, the socket mechanism 29 is connected to the positioning plate 21 through the supporting base 28, the socket mechanism 28 is arranged corresponding to the plug mechanism 110, and the socket mechanism 29 is provided with: the socket mechanism 29 can perform position fine adjustment on the supporting base 28 through the planar spiral spring 27 and can correspond to the plug mechanism 110, the overturning shaft 24 is arranged on the lower surface of the socket mechanism 28, the overturning collision block 23 is used for driving the rainproof cover 210 to open around the overturning shaft 24, and the torsion spring 22 is arranged on the overturning shaft 24 and used for accumulating energy.

The specific implementation process of the connection of the energy source and the signal transmission line of the electric automatic plugging system is as follows:
after the upper frame 100 and the container spreader 101 are mechanically locked (with the locking and unlocking mechanism of the container spreader), the floating plug mechanism 1 is located above the floating socket mechanism 2, the host controls the driving oil cylinder 12 to contract, the driving folding arm structure 11 extends downwards along the sliding rail 15, and pushes the plug mechanism support 13 and the plug mechanism 110 to move downwards integrally, when the thick guide shaft 18 enters the horn guide hole 26, the floating socket mechanism 2 is not normally located right below the floating plug mechanism 1 due to the reasons of structure manufacturing error, structure deformation, the gap between the upper frame 100 and the container spreader 101 for mechanical locking, and the like, at this time, the thick guide shaft 18 continues to move downwards under the driving of the driving oil cylinder 12, and the socket mechanism 29 is shifted to press the planar coil spring 27 to move right below the floating plug mechanism 1 through the horn guide hole 26, the thick guide shaft 18 continues to move downwards after entering the horn guide hole 26, when the rainproof cover 210 is driven to turn over and open around the turning shaft 24 by striking the flip-up striking block 23, the torsion spring 22 is twisted and energy is accumulated.
After the rain cover 210 is completely opened, the driving oil cylinder 12 continues to drive the plug mechanism support 13 and the plug mechanism 110 to integrally move downwards, the accurate guide shaft 17 is inserted into the accurate guide hole 25, the socket mechanism 29 continues to be stirred to extrude the planar spiral spring 27 to move to the position right below the floating plug mechanism 1, and at the moment, the plug mechanism 110 and the socket mechanism 29 meet the butt joint condition.
The driving cylinder 12 continues to contract, and the driving pushes the plug mechanism bracket 13 and the plug mechanism 110 to move downwards, so that the plug mechanism 110 is butted with the socket mechanism 29, and at this time, the butting of the plug in the plug mechanism 110 and the socket in the socket mechanism 29 is completed. The driving oil cylinder 12 continues to contract, the driving plug mechanism support 13 continues to move downwards, and the compression spring 16 is squeezed to store energy until the plug mechanism support 13 is contacted with the plug mechanism 110, so that the connection action is finished. When the upper frame and the container spreader do lifting action, the energy stored by the compression spring 16 can make up for the reserved slack rope gap and the structural deformation under different loads.
The action process of the energy source and the signal transmission line separation is completely opposite to the connection process, and the energy accumulated by the torsion spring 22 can ensure that the rain cover 210 is turned over and closed.
