Problems solved by technology

The watertight doors of the former structure are primitive in action and bulky, and can only be manually operated on the spot. Not only is the operation laborious and labor-intensive, but also the sealing effect is not ideal; The operating space is more than twice the body area, and at the same time, most of the remote control of watertight doors adopts tradi...

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1 to Figure 7 As shown, a watertight door includes a door frame 1, a door panel 2, a hydraulic power system 3 and a control system 4; the door frame 1 and the door panel 2 are connected by hinges, and the top and bottom of the door frame 1 are respectively provided with a closing / opening cylinder 5, which The cylinder body and the end of the piston rod are respectively hinged with the door frame 1 and the door panel 2; when the piston rod of the closing / opening cylinder 5 is retracted, the sliding door is closed; when the piston rod is stretched out, the pushing door is opened.

[0028] Such as figure 2 As shown, the inner side of the door frame 1 is provided with a number of symmetrically distributed fixed wedges 6 around the edges, and a fixed shaft seat 7 is provided at the position corresponding to each di...

Abstract

The invention discloses a watertight door which is characterized by comprising a door frame, a door sheet, a hydraulic power system and a control system. The door frame and the door sheet are connected through a hinge, a closing/opening oil cylinder is respectively arranged at the top and the bottom of the door frame, and cylinder bodies of the closing/opening oil cylinders and the ends piston rods of the closing/opening oil cylinders are respectively hinged to the door frame and the door sheet. When the piston rods of the closing/opening oil cylinders (5) contract inwards, a sliding rood is closed. When the piston rods extend outwards, the sliding door is opened. The watertight door can be remotely controlled and is high in safety performance.

Description

technical field [0001] The invention relates to a door, in particular to a watertight door. Background technique [0002] At present, semi-submersible drilling platforms and offshore facilities of similar structures generally use watertight doors as the entrances and exits for staff to enter and exit underwater internal cabins. Due to the large opening area and frequent movements of watertight doors, their sealing performance and working reliability must be absolutely guaranteed . The original watertight door is generally designed as a manual buckle structure or a screw screw structure, or a hydraulic sliding structure. The watertight doors of the former structure are primitive in action and bulky, and can only be manually operated on the spot. Not only is the operation laborious and labor-intensive, but also the sealing effect is not ideal; The operating space is more than twice the body area, and most of the long-distance control of the watertight door adopts the traditi...
