[0026] Working principle:

[0027] Flip open working state

[0028] By controlling the external power supply of the hydraulic gate hoist 403, the hydraulic gate hoist 403 starts to work, and the hydraulic gate hoist 403 pushes the connecting head 404 and the connecting plate 405 at the end to move, so that the connecting plate 405 applies thrust to the gate 305, and the upper end of the gate 305 is in a state of connection and rotation with the infrastructure. The pulley 304 on the mounting block 303 on the outer wall of the gate 305 is restricted by the position and the inner wall of the gate 305 slides up and down, so that the gate 305 is supported by the pulley 304 and the movement is more stable, and the slider 301 on the round rod 302 on the outer wall of the mounting block 303 slides in the slide groove 2 on the infrastructure 1, so that the gate 305 is flipped open under the restriction of the slide groove 2.

[0029] Close working state

[0030] When the hydraulic gate opening machine 403 contracts and returns to its original state, the outer wall of the gate 305 and the first sealing strip 307 and the second sealing strip 9 on the first mounting strip 306 are in a sealed state when closed. Finally, the hydraulic cylinder 5 is controlled to contract the connecting rod 6. When the connecting rod 6 is pulled upward, when the connecting rod 6 applies pressure to the blocking rod 7, the blocking rod 7 and the infrastructure 1 have a fulcrum connection effect, so that the blocking rod 7 can be deflected from the inside of the infrastructure 1, thereby achieving the effect of auxiliary blocking of the gate 305.
