[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1.

[0050] Working principle: When the present invention is in use, the ports of two sections of power cable protection pipes are contacted with both ends of the hot melt butt welding machine 6;

[0051] A second motor 107 is used to drive the first drive shaft 104 to rotate. The rotation of the first drive shaft 104 drives the rotation of the first shaft sleeve 208 on its outer ring. The rotation of the first shaft sleeve 208 drives the rotation of the second bevel gear 209. The rotation of the second bevel gear 209 drives the rotation of the first bevel gear 206. The rotation of the first bevel gear 206 drives the rotation of the second screw rod 204. The rotation of the second screw rod 204 drives the two fixing blocks 303 on it to move towards each other. The movement of the fixing blocks 303 towards each other drives the movement of the connecting bracket 302 on its outer ring. The movement of the connecting bracket 302 drives the movement of the support frame 301. The movement of the support frame 301 drives the movement of the deflection mechanism 4 on it. Furthermore, the mutual approach of the two deflection mechanisms 4 drives the mutual approach of the clamps 407 on them, clamping and fixing the two sections of the power cable protection pipe;

[0052] The two mutually approaching ends of the two sections of the power cable protection pipe are subjected to hot melting operation by a hot melt butt welding machine 6. After the hot melting is completed, the first motor 106 is used to drive the first screw rod 103 to rotate. The rotation of the first screw rod 103 drives the two moving brackets 201 to move away from each other, and thus the power cable protection pipes on the two moving brackets 201 move away from each other;

[0053] An electric cylinder 508 is used to drive the straight rack 507 to move. The movement of the straight rack 507 drives the rotation of the external gear 505. The rotation of the external gear 505 drives the rotation of the central shaft 503. The rotation of the central shaft 503 drives the deflection of the deflection bracket 504. The deflection of the deflection bracket 504 drives the deflection of the hot melt butt welding machine 6, moving the hot melt butt welding machine 6 away from between the two sections of the power cable protection pipe;

[0054] Subsequently, the two mutually approaching ends of the two sections of the power cable protection pipe are brought into close contact again by the rotation of the first screw rod 103;

[0055] Finally, another second motor 107 is used to drive the second drive shaft 105 to rotate reciprocally. The rotation of the second drive shaft 105 drives the rotation of the second shaft sleeve 212 on its outer ring. The rotation of the second shaft sleeve 212 drives the rotation of the fourth bevel gear 213 on its outer ring. The rotation of the fourth bevel gear 213 drives the rotation of the third bevel gear 210. The rotation of the third bevel gear 210 drives the rotation of the transmission shaft 205;

[0056] The rotation of the transmission shaft 205 drives the rotation of the third shaft sleeve 305 on its outer ring. The rotation of the third shaft sleeve 305 drives the rotation of the fifth bevel gear 306 on its outer ring. The rotation of the fifth bevel gear 306 drives the rotation of the sixth bevel gear 308. The rotation of the sixth bevel gear 308 drives the rotation of the rotating shaft 307. The rotation of the rotating shaft 307 drives the rotation of the worm 309 connected to it. The rotation of the worm 309 drives the rotation of the arc-shaped rack 406. The rotation of the arc-shaped rack 406 drives the arc-shaped plate 405 to deflect along the arc-shaped bar 401;

[0057] By means of the reciprocating deflection of two arc-shaped plates 405, the power cable protection pipe clamped by the fixture 407 on one side of the two arc-shaped plates 405 can be reciprocally deflected, thereby accelerating the hot melting speed of the two sections of the power cable protection pipe. Subsequently, the deflection of the power cable protection pipe is stopped, and after the connection part of the power cable protection pipe is cooled, the hot connection operation is completed.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
