Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a sliding induction door. Background Art

[0002] In ship design, stability is a very critical factor, especially damage stability. During the use of ships, marine accidents may occur, causing damage to the hull and allowing seawater to enter the hull. Therefore, during the design process of the ship, it is necessary to consider that the ship has a certain degree of anti-sinking ability, that is, when one or more compartments of the ship are damaged and water enters, it can still maintain a certain buoyancy and stability.

[0003] There are many cabin doors on the ship, including many fire doors on Class A fireproof bulkheads, especially those close to the side. They are closed under normal navigation. When the ship is damaged and flooded, under certain damage conditions, these normally closed doors will hinder the flow of incoming water, significantly limiting the free flow of incoming water, resulting in an intermediate flooding stage with a very low probability of survival. Although the amount of water inflow is not the largest at this stage, it may also be the most dangerous state, such as causing a greater roll. There is currently no technical solution to solve this problem. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a sliding induction door in order to overcome the above-mentioned defects in the prior art.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A sliding induction door, comprising a fire door arranged between a steel enclosure wall of a ship cabin and a deck; the fire door is a sliding door; a slide rail is fixedly arranged on the steel enclosure wall, and a connecting device is arranged on the top of the sliding door; the sliding door is hung on the slide rail through the connecting device; a stop device for stopping the sliding door from sliding on the slide rail is also arranged on the steel enclosure wall; the sliding induction door also comprises an accumulator, a water level switch and a driving mechanism for driving the sliding door to move on the slide rail; the sliding induction door also comprises a control system and a driving control device which can send an instruction to move the sliding door to the driving mechanism after receiving a signal sent by the water level switch; the accumulator, the water level switch and the driving mechanism are all connected to the control system and the driving control device through electric wires.

[0007] The sliding induction door also includes a local control handle for manually opening or closing the sliding door; the local control handle is connected to the control system and the drive control device. When the ship fails and the power is cut off, causing the sliding door to fail to open automatically, the sliding door can be manually opened or closed by the local control handle.

[0008] There are two local control handles, which are respectively arranged on the inner wall and the outer wall of the cabin. The local control handles are arranged on both sides of the sliding door for easy operation.

[0009] The sliding induction door also includes an alarm, which is connected to the control system and the drive control device. When the flooding liquid level switch is triggered, the alarm sounds an alarm to remind the crew and passengers, thus playing a warning role.

[0010] There are two alarms, which are respectively arranged on the inner wall of the cabin and the outer wall of the cabin. The alarms are arranged on both sides of the sliding door, so that the alarm sound can be transmitted in a wider range.

[0011] The flooding level switch is installed above the deck. When the seawater entering the ship reaches the sliding door, the flooding level switch can be triggered immediately, sending a signal to the control system and drive control device in time, so that the sliding door is opened in time to increase the safety of the ship.

[0012] There are two water level switches, which are respectively arranged inside and outside the cabin.

[0013] There is a rubber gasket between the sliding door and the deck. In this way, the sealing can be improved and the fire resistance of the door can be ensured.

[0014] The steel enclosure wall is provided with a slide rail fixing device, and the slide rail is fixed to the steel enclosure wall through the slide rail fixing device. In this way, the slide rail structure is more stable, providing strong support for the smooth sliding of the sliding door.

[0015] A cover is also fixed on the steel surrounding wall, and the cover is arranged outside the slide rail and the driving mechanism. The cover shields the slide rail, the driving device, the fixing device and other mechanisms, and plays a role in safety and beauty.

[0016] The beneficial effects of the present invention are as follows: the sliding induction door of the present invention eliminates the influence of the fire door that causes the intermediate flooding stage, greatly improves the survival probability of the damage calculation, can improve the stability of the ship, make the overall layout of the whole ship more flexible, more convenient to meet the layout of different needs, and reduce the influence of the cabin layout on the damage stability calculation result.

[0020] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a sliding induction door includes a fire door arranged between a steel enclosure wall 21 of a ship cabin and a deck 20; the fire door is a sliding door 1.

[0022] In this embodiment, the sliding door is made of a stainless steel frame and the door leaves are made of stainless steel.

[0023] A slide rail 4 is fixedly arranged on the steel enclosure 21 , and a connecting device 7 is arranged on the top of the sliding door 1 ; the sliding door 1 is hung on the slide rail 4 via the connecting device 7 ; a stop device 6 for stopping the sliding door from sliding on the slide rail is also arranged on the steel enclosure 21 .

[0024] A slide rail fixing device 5 is fixedly provided on the steel surrounding wall 21 , and the slide rail 4 is fixed to the steel surrounding wall 21 through the slide rail fixing device 5 .

[0025] A cover 9 is also fixedly provided on the steel surrounding wall 21, and the cover 9 is arranged outside the slide rail 4 and the driving mechanism 8. The cover shields the slide rail, the driving device, the fixing device and other mechanisms, and plays a role in safety and aesthetics.

[0026] The sliding induction door further comprises a control system and a drive control device 3, an accumulator 2, a water level switch 11 and a drive mechanism 8 for driving the sliding door to move on the slide rail.

[0027] The control system and the drive control device 3 are connected to the ship power supply 22 via electric wires.

[0028] The accumulator 2, the water level switch 11 and the drive mechanism 8 are all connected to the control system and the drive control device 3 through electric wires.

[0029] The control system and the drive control device 3 may send a command to move the sliding door 1 to the drive mechanism 8 after receiving a signal sent by the immersion liquid level switch 11 .

[0030] The sliding induction door also includes a local control handle 13 for manually opening or closing the sliding door; the local control handle 13 is connected to the control system and the drive control device 3.

[0031] In this embodiment, there are two local control handles 13, and the two local control handles are respectively arranged on the inner wall and the outer wall of the cabin.

[0032] The sliding induction door further includes an alarm 12 , which is connected to the control system and the drive control device 3 .

[0033] In this embodiment, there are two alarms 12, which are respectively arranged on the inner wall and the outer wall of the cabin.

[0034] In this embodiment, the water level switch 11 is arranged above the deck.

[0035] In this embodiment, there are two water level switches 11, which are respectively arranged inside the cabin and outside the cabin.

[0036] In order to improve the sealing performance between the sliding door and the deck under normal conditions, a rubber gasket 10 is provided between the sliding door 1 and the deck 20. In this embodiment, the rubber gasket is a fire-resistant rubber gasket to ensure the fireproof performance of the door.

[0037] Under normal conditions, the sliding door is in a closed state and is used as a regular fire door for the cabin.

[0038] When a ship is damaged during use, the hull is damaged and seawater enters the ship. When the seawater entering the ship reaches the sliding door, the flooding level switch sends a signal to the control system and the drive control device when the sensor detects flooding. After receiving the signal, the control system and the drive control device send a command to the drive mechanism to move the sliding door. Driven by the drive mechanism, the sliding door moves along the slide rail, and the sliding door opens, allowing the incoming water to flow freely, eliminating the influence of the intermediate flooding stage in the calculation process, thereby increasing the survival probability value of the damage calculation and increasing the safety of the ship.

[0039] When the water level switch is triggered, the alarm sounds to alert the crew and passengers and serve as a warning. It is set on both sides of the sliding door.

[0040] There are two sources of power for the control system and drive control device, one is the ship power supply and the other is the accumulator. When the ship power supply cannot be used due to marine damage, the accumulator can be used for on-site manual operation. The function of the accumulator is to provide power for manual operation in the event of power failure.

[0041] In this embodiment, in order to prevent the sliding door from being unable to open automatically due to a power outage caused by a malfunction in the ship, a local control handle is provided, through which the sliding door can be manually opened or closed, and the local control handle is provided on both sides of the sliding door.

[0042] The sliding induction door of the present invention eliminates the influence of the fire door that causes the intermediate flooding stage, greatly improves the survival probability of the damage calculation, can improve the stability of the ship, make the overall layout of the whole ship more flexible, more convenient to meet the layout of different needs, and reduce the influence of the cabin layout on the damage stability calculation result.

[0043] The advantages of the present invention are:

[0044] (1) Reduce the adverse effects of flooding during the intermediate stage of damage calculation for passenger ships;

[0045] (2) It greatly facilitates the overall layout design of the ship;

[0046] (3) It is easier to meet the requirements of shipowners, increase design flexibility and enhance market competitiveness.
