The following describes the docking step of wind power automatic docking in embodiment 2 in detail, so that a person skilled in the art can fully understand the technical scheme in embodiment 2, and the specific steps are as follows:
Step 1: firstly, the locomotive is in butt joint with a vehicle behind the locomotive, a first three-way electromagnetic valve 622 on a fourth air pipe 618 connected with a locomotive train hose is powered on, the train hose is conducted to an air path of an outer air cylinder rear cavity 604, and pressure air enters the outer air cylinder rear cavity 604 through the fourth air pipe 618, so that an inner air cylinder 608 body serving as an outer piston rod extends out, the mechanical butt joint body 4 and the wind power butt joint body 5 are pushed to move towards the direction of the vehicle behind the locomotive until the mechanical butt joint body 4 at the rear of the locomotive is in butt joint with the mechanical butt joint body 4 at the front of the vehicle, a first protruding part 401 at the rear of the locomotive is completely inserted into a first recessed part 402 at the front of the vehicle, and the first protruding part 401 at the front of the vehicle is completely inserted into the first recessed part 402 at the rear of the locomotive, so that positioning is completed.

Step 3, after the standard sealing rings 505 on the valve rods 524 of the two wind power butting bodies 5 are tightly attached, the pressure air on the train head enters the train hose of the rear vehicle after passing through the fifth air pipe 619, the third air pressure channel 617, the core rod 616, the hollow part of the inner piston rod 612, the eighth vent 629, the rear chamber 527, the middle chamber 526, the middle chamber vent 539 and the valve rods 524 of the rear vehicle, the middle chamber vent 539, the middle chamber 526, the rear chamber 527, the eighth vent 629, the hollow part of the inner piston rod 612, the core rod 616, the third air pressure channel 617 and the fifth air pipe 619, and then enters the train hose of the rear vehicle; meanwhile, when the pressure air enters the valve rod 524, part of the pressure air enters the front chamber 525 through the front chamber vent hole 538, and the pressure air in the front chamber 525 is divided into two paths, wherein one path of pressure air enters the delay air cylinder rear chamber 533 through the seventh vent hole 537, the outer air pipe 535 and the sixth vent hole 536; one path enters the locking air cylinder front chamber 704 through the blind channel 543, the first air pipe 719 and the third air hole 706, so that the locking piston 703 extrudes the locking spring 708, the locking piston rod 709 retracts and drives the locking hook 710 to retract, and the locking hook 710 rotates clockwise while retracting, so that the locking hook is hung on the locking pin 702 of the rear vehicle wind power docking body 5; when the pressure air enters the valve rod 524 of the rear vehicle, part of the pressure air enters the front chamber 525 through the front chamber vent hole 538, and the pressure air in the front chamber 525 enters the front chamber 704 of the locking air cylinder through the blind duct 543, the first air pipe 719, the second three-way electromagnetic valve 720 in a power-off state and the third air hole 706, so that the locking piston 703 presses the locking spring 708, the locking piston rod 709 retracts and drives the locking hook 710 to retract, the locking hook 710 rotates clockwise while retracting, and is hung on the locking pin 702 of the locomotive wind power docking body 5, and when the pressure air enters the rear chamber 527, a small amount of pressure air enters the front chamber 532 of the delay air cylinder through the fifth vent hole 534.
And 4, the other subsequent vehicles are sequentially connected in a butt joint mode according to the wind path sequence in the step, and the difference is that the locomotive is replaced by a front vehicle.
The separation steps of the wind power automatic docking and separating device for the two vehicles are as follows:
Step 1: the second three-way electromagnetic valve 720 is used for electrically cutting off the air path from the locking air cylinder front chamber 704 to the locking air cylinder front chamber 704, and the second three-way electromagnetic valve 720 is used for communicating the locking air cylinder front chamber 704 to the outside, so that the pressure air of the locking air cylinder front chamber 704 is discharged, the locking piston 703 is pushed by the locking spring 708, the locking piston rod 709 extends, and the locking hook 710 moves forwards while rotating upwards, so that unhooking is completed.
Step 2, when the second three-way electromagnetic valve 720 is electrically connected to the passage of the locking air cylinder front chamber 704 to the outside, the vehicle controller starts timing, after reaching the preset time, the first three-way electromagnetic valve 622 is controlled to cut off the power supply of the train hose to the outer air cylinder rear chamber 604 and the air passage of the detection cabin 405, and the detection cabin 405 and the outer air cylinder rear chamber 604 are enabled to be identical to each other through the first three-way electromagnetic valve 622, so that the pressure air in the outer air cylinder rear chamber 604 and the detection cabin 405 is discharged, the outer piston rod is retracted, the two abutted mechanical abutted bodies 4 are separated, when the mechanical abutted bodies 4 are separated, the detection plunger 406 returns (as shown in a state of fig. 4), so that the first air vent 410 and the second air vent 412 are communicated, and the pressure air in the inner air cylinder rear chamber 611 is enabled to be discharged to the outside through the second air pressure channel 614, the third air pipe, the first air vent 410, the annular groove 409 and the second air vent 412 after the separation of the mechanical abutted bodies 4, and the inner air cylinder rear chamber 723 is enabled to retract to the first air vent hole 410 and the second air vent 412, and the mechanical abutted body 403 is retracted to the first abutted body 403 to the one end of the mechanical abutted body 4 far from the first abutted body 4. When the two wind power butt-joint bodies are separated, the pressure air of the rear chamber 533 of the time delay air cylinder is rapidly discharged to the outside through the sixth vent 536, the outer air pipe 535, the seventh vent 537, the front chamber 525 and the front chamber vent 538, while the pressure air of the front chamber 532 of the time delay air cylinder can only be slowly discharged into the rear chamber 527 through the narrow through hole of the fifth vent 534 and is discharged to the outside through the gap between the annular boss 528 of the valve rod 204 and the end wall of the rear chamber 527 near the middle chamber 526. Due to the obstruction of the pressure air in the front chamber 532 of the delay air cylinder, the annular bulge 528 of the valve rod 524 is delayed to contact with the end wall of the rear chamber 527 near the middle chamber 526, and the separated train pipe pressure air is rapidly discharged to the outside from the gap between the annular bulge 528 of the valve rod 524 and the end wall of the rear chamber 527 near the middle chamber 526, so that the separated train pipe pressure air brakes the separated train pipe foundation brake device, and the separated train pipe brake device is prevented from slipping after the vehicle is separated. The front part connected with the locomotive is separated from the train pipe to supplement air to the locomotive continuously, and after the valve rod 524 is closed and the air outlet stops exhausting, the air pressure of the train pipe is recovered to be constant in time, so that the front part of the train pipe is naturally relieved by the basic brake device of the vehicle.
Step 3: after the preset preparation time in the vehicle-mounted controller is reached, the second three-way electromagnetic valve 720 loses power to connect the passage from the locking reservoir front chamber 704 to the front chamber 525, and cuts off the passage from the locking reservoir front chamber 704 to the outside, so as to prepare for the next butt locking.
Because the storage battery is arranged on each vehicle, after the wind power automatic docking and separating device is separated, all three-way electromagnetic valves and two-way electromagnetic valves can be controlled by the controller.
