Fig. 3 is a schematic structural view of a bead lock locking groove and a bead lock sliding groove provided in an embodiment of the present disclosure, and it can be seen in fig. 3 that the depth of the bead lock sliding groove 13 is reduced in a rotation direction in which the opening and closing door 2 is changed from open to closed.
In the rotating direction of the opening and closing door 2, the depth of the bead lock sliding groove 13 is reduced, so that the resistance of the opening and closing door 2 can be reduced, and the opening and closing efficiency of the opening and closing door 2 is improved.
Fig. 4 is a flowchart of a method for using an underwater isolation door device provided in an embodiment of the present disclosure, and as can be seen from fig. 4, an embodiment of the present disclosure provides a method for using an underwater isolation door device, where the underwater isolation door device is implemented by using the foregoing underwater isolation door device, and the method for using the underwater isolation door device includes:
s101: when the opening and closing door in the underwater isolation device is in a closed state, the bead lock roller in the bead lock assembly in the underwater isolation device is positioned in the bead lock locking groove on the seat body in the underwater isolation device.
S102: and applying pushing acting force to the opening and closing door to enable the ball lock roller to roll into the ball lock sliding groove from the ball lock locking groove, wherein a pressure releasing gap is formed between the ball lock roller and the ball lock sliding groove, and the opening and closing door is pushed to open.
The base body and the opening and closing door in the underwater isolation door device are in hinged fit, the opening and closing of the opening and closing door can be realized by pushing and closing the opening and closing door, and the realization of water flow control is ensured. The bead lock locking groove that has on the pedestal and with the bead lock sliding tray of bead lock locking groove intercommunication can play the mating reaction with the bead lock subassembly in the isolation door device under water. The connecting plate links to each other and the face of connecting plate offsets with the pedestal with the door that opens and shuts in the pearl lock subassembly, and the door that opens and shuts provides the support for the pearl lock subassembly, and the connecting plate provides support and installation space for other structures in the pearl lock subassembly. The connecting plate is provided with a roller placing hole, and the ball lock roller is positioned in the roller placing hole. The connecting plate can provide support for other structures in the bead lock assembly; on the direction that the connecting plate is close to the pedestal, the cross section that the hole was placed to the roller reduces gradually, and the area of the minimum cross section that the hole was placed to the roller is less than the diameter of pearl lock roller, and the hole is placed to the roller can be exposed outside the connecting plate with some of pearl lock roller when playing limiting displacement to the pearl lock roller. The roller is placed the hole and is just to pearl lock locking groove or just to pearl lock sliding tray, and the pearl lock roller is placed the maximum depth of the part that the hole exposes by the roller and is the same with the maximum depth in pearl lock locking groove, and the pearl lock roller can realize that the locking is identical and sealed with pearl lock locking groove, guarantees the locking of opening and shutting door and pedestal, increases the stability that keeps closed state between opening and shutting door and the pedestal. And when the opening and closing door needs to be opened, the bead lock roller overcomes certain acting force and enters the bead lock sliding groove from the bead lock locking groove, the pressure between the bead lock roller and the bead lock sliding groove is small, water flow can enter a gap between the bead lock roller and the bead lock sliding groove, the water pressure which can be received when the opening and closing door is opened is reduced, the water pressure received in the closing process of the underwater isolating door is very small, and the opening and closing efficiency of the opening and closing door can be improved so as to improve the opening and closing efficiency of the underwater isolating door device. The connecting barrel and the limiting spring in the ball lock assembly provide support and reset power for the ball lock roller, and the opening and closing of the opening and closing door can be carried out for multiple times.
When the opening/closing door needs to be changed from the opened state to the closed state, the opening/closing door is controlled to be changed from the state in step S102 to the state in step S102.
Although the present disclosure has been described with reference to specific embodiments, it will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the disclosure.
