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 traditional relay control circuits, which are large in size
For a semi-submersible drilling platform, the underwater structural units are relatively independent, and the internal cabins are usually distributed at different levels about 20m from the keel, and the layout space is limited, and the watertight doors require high pressure resistance. doors obviously don't apply

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 to Figure 7 As shown, the present invention 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 hingedly connected, and the top and the bottom of the door frame 1 are respectively provided with a closing / opening oil cylinder 5, and 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 retracts, the sliding door is closed; when the piston rod is extended, the pushing door is opened.

[0020] like 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 diagonal wedge 6 arou...

Abstract

The invention relates to a watertight door device which is characterized by comprising a door frame, a door plate, a hydraulic power system and a control system. The door frame is connected with the door plate by a hinge, linkage of a closed/open hydro-cylinder and a locked/loosened hydro-cylinder is employed to automatically perform the motions of closing-locking and delocking-opening; the control system is composed of a plurality of regional control cabinets and a centralized-control box, and can carry out centralized monitoring on the state of the watertight door device and remotely or locally control opening and closing. Compared with the traditional manual type watertight door, the watertight door device provided by the invention not only reduces heavy physical strength dissipation, but also is stable and simple in operation and high in safety and reliability. Meanwhile, compared with the traditional hydraulic sliding type watertight door, the watertight door device is compact instructure, light in weight and small in occupied space.

Description

technical field [0001] The invention relates to a watertight door, in particular to a hydraulic hinged watertight door device designed for the underwater interior compartment of a semi-submersible drilling platform. 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 opera...
