Description

Fire-extinguishing type cabin is with safe type watertight chamber door Technical Field The invention relates to the technical field of watertight doors of cabins, in particular to a safe watertight chamber door for a fire extinguishing type cabin. Background Watertight doors are key devices for separating ship cabins, are commonly used in ships such as drilling ships (barges) and semi-submersible transport ships, and can be classified into different grades according to different installation positions, but are required to have good sealing performance and fireproof capability. The marine vessel is sailed on sea for several months, and once a fire disaster occurs in a certain cabin, the watertight door can effectively prevent the fire disaster from spreading to the adjacent cabin, and the fire disaster is limited in a single cabin. At present, the heat insulation performance of the conventional watertight door is obviously insufficient compared with that of a cabin wall plate. When a fire disaster occurs, heat is easily and rapidly transferred to one side outside the cabin through the watertight door, so that the temperature near the door body is rapidly increased, serious influence is caused on an outside evacuation channel, and the escape safety of personnel is threatened. In order to improve the fireproof sealing effect, the existing partial watertight door is provided with a fire-swelling adhesive tape at the sealing position of the door frame or the door body. When a fire disaster happens, the adhesive tape is heated and expanded, so that the sealing performance can be temporarily enhanced, fresh air is prevented from entering a fire scene, and a certain choking effect is achieved on the fire disaster. However, the fire-expandable adhesive tape has obvious defects that the adhesive tape is difficult to retract after fire extinguishment, so that a watertight door cannot be normally opened, and the expandable adhesive tape is permanently invalid after high-temperature ablation and cannot be reused. This means that the watertight door will lose normal opening and closing functions during the following navigation of several months, forming a safety hazard, the shipside has to temporarily change the route, change the adhesive tape or repair the door body nearby the shore, seriously affect the navigation plan and economy, and therefore, a watertight door structure capable of actively insulating heat, dynamically enhancing sealing in fire and being reused after fire is needed. Based on the above, the invention provides a safe watertight chamber door for a fire extinguishing type cabin. Disclosure of Invention The invention aims to solve the problems in the prior art, and provides a safe watertight chamber door for a fire extinguishing type cabin. In order to achieve the above purpose, the present invention adopts the following technical scheme: The safe watertight chamber door for the fire extinguishing type cabin comprises a frame body which is welded with the cabin in a sealing way, wherein one side of the frame body is connected with a watertight door body through a hinge, and the watertight door body is sequentially provided with a heat insulation heat exchange body, a watertight internal pressure body and a safe lock control body from outside to inside; the heat insulation heat exchange body comprises a heat insulation plate and a heat exchange base plate which is in pressing fit with the heat insulation plate, and a heat exchange pipeline is arranged in the heat exchange base plate and used for circularly exchanging heat to reduce the temperature outside the watertight door body; The watertight internal pressure body comprises a sealing substrate, an inner notch is formed in the outer side wall of the sealing substrate, a rubber sealing gasket for improving sealing performance is arranged in the inner notch, a sealing outer groove matched with the rubber sealing gasket is formed in the inner wall of the frame, and a water pressure sealing piece is further arranged in the inner notch and used for improving the sealing effect of the rubber sealing gasket when a fire disaster occurs; The safe lock accuse body includes interior lock base plate, interior lock base plate is connected with the control rotary disk through the control shaft that runs through interior pressure body of watertight and thermal-insulated heat transfer body lateral wall, the control shaft is connected with the lock post through allied oneself with accuse lock controlling part, the inside interior trigger formula fire extinguishing atomizer that is provided with of lock post, cabin inner wall is provided with a plurality of interior hasp that use with the lock post adaptation.
