The purpose of closing the left explosion-proof door and the right explosion-proof door; on the contrary, switching the two-position four-way reversing valve to the right position, the oil enters the rod chamber of the right push-pull cylinder A through the hydraulic pump and the two-position four-way reversing valve, pushing the piston and piston rod of the right push-pull cylinder A to move right, and the oil in the rod chamber of the right push-pull cylinder A is squeezed into the rod chamber of the left push-pull cylinder A, and the oil in the rod chamber of the left push-pull cylinder A pushes the piston and piston rod of the left push-pull cylinder A to move to the left, and the left push-pull cylinder A and the right push-pull cylinder A respectively drive the left explosion-proof door and the right explosion-proof door to rotate relative to the door frame, thereby achieving the operation of opening the left explosion-proof door and the right explosion-proof door.

5. According to the intelligent waterproof gate of claim 4, It is characterized in that The left sealing rib includes a rib A and a rib B that are parallel to each other and spaced apart. The rib A and the rib B are welded to the right side of the left explosion-proof door. A rear base plate is vertically connected between the rib A and the rib B. The rib A, the rib B and the rear base plate are vertically arranged, and multiple groups of threaded columns are uniformly welded along the length direction of the rear base plate. The left sealing rib also includes a rib C and a rib D that are parallel to each other and spaced apart. The inner walls of the rib C and the rib D are respectively vertically mounted with an inner baffle A and an inner baffle B. The outer sides of the rib C and the rib D are vertically welded with a front base plate. The front base plate, the rib A and the rib B are vertically connected to the right side of the left explosion-proof door. Edge C, rib D, inner baffle A and inner baffle B are all arranged vertically, and there are a first preset gap and a second preset gap between the inner baffle A and the inner baffle B, and between the inner baffle A and the front substrate respectively. The inner baffle A and the inner baffle B are on the same plane, the threaded column passes through the rubber strip and the first preset gap in sequence and is connected to the connecting nut, the connecting nut abuts against the inner baffle B and the inner baffle B, and the two end surfaces of the rubber strip abut against the rear substrate, the inner baffle A, and the inner baffle B respectively, and nut installation avoidance holes matching the position of the threaded column are arranged at intervals along the length direction of the front substrate.

6. According to the intelligent waterproof gate of claim 5, It is characterized in that The cross section of the rubber strip is rectangular, and two groups of symmetrically arranged compression inner holes are opened along the length direction of the rubber strip.

7. According to claim 6, the intelligent waterproof gate, It is characterized in that The right sealing rib has the same structure as the left sealing rib.

8. According to the intelligent waterproof gate of claim 7, It is characterized in that The self-locking device of the left explosion-proof door includes an ear plate A installed on the door frame and a push-pull cylinder A installed on the left explosion-proof door. The telescopic end of the push-pull cylinder A is installed with a wedge block A through a pin shaft A. The ear plate A is provided with a lock hole A that cooperates with the wedge block A. The push-pull cylinder A drives the wedge block A and the ear plate A to lock or unlock each other. The push-pull cylinder A is installed on the left explosion-proof door through a cylinder fixing seat A. The left explosion-proof door is also provided with a cylinder fixing seat A for guiding the wedge block A. The cylinder fixing seat A has a guide hole A through which the wedge block A passes.

9. According to the intelligent waterproof gate of claim 8, It is characterized in that The right explosion-proof door self-locking device 7 includes an ear plate B installed on the right explosion-proof door and a push-pull cylinder B installed on the right explosion-proof door. The telescopic end of the push-pull cylinder B is installed with a wedge block B through a pin shaft B. The ear plate B is provided with a lock hole B that cooperates with the wedge block B. The push-pull cylinder B drives the wedge block B and the ear plate B to lock or unlock each other. The push-pull cylinder B is installed on the right explosion-proof door through a cylinder fixing seat B. The right explosion-proof door is also provided with a cylinder fixing seat B for guiding the wedge block B. The cylinder fixing seat B has a guide hole B through which the wedge block B passes.

10. According to claim 9, the intelligent waterproof gate, It is characterized in that The left explosion-proof door self-locking device and the right explosion-proof door self-locking device are respectively provided with four groups.
