Description

Marine vertical evacuation passageway

Technical Field

The utility model relates to a boats and ships or ocean platform's lifesaving equipment, especially one kind withdraw to the passageway of withdrawing of boarding platform from boats and ships or ocean platform that meet a difficult, belong to marine life saving technical field.

Background

The marine evacuation system is used for assisting people to evacuate rapidly when emergency happens to a ship or a marine platform, the marine vertical evacuation channel is an important unit of the marine evacuation system, and the evacuated people evacuate to a boarding platform through the marine vertical evacuation channel so as to get on a lifeboat and drive away from a distressed sea area.

The existing marine vertical evacuation channel is mainly divided into two types according to the different evacuation heights, one type is suitable for passenger rollers and small mail carriers with the evacuation height of less than 15 meters, and the existing marine vertical evacuation channel is a linear channel formed by combining a steel ring, conical channel underwear, resistance cloth, elastic knitted fabrics and a channel jacket. The evacuated people slide down from the pipeline of the linear passage, and people outside the passage cannot clearly see the inside evacuation condition. When the evacuation personnel suddenly happen in the passage jacket, the personnel outside the passage jacket cannot be rescued. The gliding speed of the evacuated persons in the linear channel is uncontrollable, so that the speed of the evacuated persons sliding on the boarding platform is too high, and the injury caused by falling is caused. In addition, as the channel underwear and the resistance cloth are both made of elastic knitted fabrics, the evacuation channel is subjected to large wind resistance, so that the whole evacuation system is easy to shake, and the evacuation speed and efficiency are influenced. In addition, the straight-line channel does not have the reverse climbing escape capacity in case of any emergency on the sea surface in the evacuation process.

The other type of the novel escape passage is suitable for large-scale passenger ships or ocean platforms with the evacuation height of more than 15 meters, and is a vertical evacuation passage formed by combining a flexible sleeve woven by a net wall, a supporting steel ring, a sliding inclined plane of a zigzag net woven structure in the flexible sleeve and a steel wire rope, the sliding inclined plane of the net woven structure enables evacuation personnel to easily generate fear, and the evacuation efficiency of the evacuation personnel who are not trained professionally is easily influenced due to the fact that the evacuation passage is unfamiliar with the vertical evacuation passage. The zigzag vertical evacuation passageway requires the evacuees to change the sliding direction continuously, which is easy to cause dizziness. Be equipped with on the section of thick bamboo wall of the flexible sleeve between two-layer support steel ring and supply personnel to flee through zip fastener confined trompil, because long-time compression is placed, lead to the zip fastener ageing easily and be difficult to open, and then influence the efficiency of fleing when using.

Detailed Description

The invention will be further explained with reference to the drawings and the embodiments for large cruise ships.

As shown in fig. 1 to 3, the present embodiment is located outside the side of a large-sized cruise ship 10 in use, and includes a flexible sleeve 1 and a plurality of layers of support frames 21 fixed at intervals in the flexible sleeve 1, and the bottom support frame 21 is fixed at the center of a boarding platform 3. The flexible sleeve 1 is made of a hexagonal rope net braided fabric, and is made of Kevlar fibers which are low in density, high in strength, good in toughness, high-temperature resistant and easy to process and form. The supporting framework 21 is formed by bending and welding round steel with the diameter of 10mm, the inner diameter of the supporting framework is 1200mm-1400mm, 3 supporting rods 22 of the round steel with the diameter of 10mm, which are radially and uniformly distributed from the center of the supporting framework 21 outwards, divide the supporting framework 21 into 3 fan-shaped areas, except a vacant fan-shaped area 211 for allowing evacuation personnel to pass through, the other fan-shaped areas cover a steel plate net 23 of a rhombic grid with the short pitch of 5mm, the long pitch of 10mm and the thickness of 3mm, and then the supporting platform 2 is formed. The area of the vacant sectorial region 211 is larger than the largest cross-sectional area of a human body, the vacant sectorial regions 211 of two adjacent layers of supporting platforms 2 are arranged in a staggered mode, and the vertical distance H =1300mm between two adjacent layers of steel plate nets 23. The structure facilitates the evacuation of people from the vacant sector areas 211 of the upper supporting platform 2 to the lower supporting platform 2 for a short time, and then from the vacant sector areas 211 of the lower supporting platform 2 to the next supporting platform 2, so as to slow down the descending speed of the evacuated people, avoid the situation that the evacuated people slide into the boarding platform 3 at an excessive speed to cause tumble injury and fall injury, and also enable the evacuated people to reversely climb the upper supporting platform 2 and evacuate when emergencies occur on the sea surface or the boarding platform 3. When arriving at the flexible sleeve 1, the evacuated people can ascend the lifeboat from the boarding platform 3 to finish evacuation.

4 retractable rope rings 24 penetrating through the flexible sleeve are uniformly distributed on the outer edge of the support framework 21, and the retractable ropes 5 made of aramid fiber downwards respectively penetrate through the retractable rope rings 24 of each layer of support framework and then are fixed on the support framework 21 at the bottom layer. The 4 retractable ropes 3 can be retracted and extended through a winch of a vertical evacuation system on the side of the large-scale passenger liner.

As shown in fig. 4, a dark color fabric 11 having a height of 150mm to 200mm is provided around the outer periphery of the net fabric of the flexible sleeve 1, and the dark color fabric 11 of the present embodiment is black polyester fabric, which has a certain light-shielding property and can reduce the fear of evacuees. Vertical slits 12 are arranged on the rope net braided fabric between two adjacent supporting platforms 2, and two sides of each vertical slit 12 are connected through nylon tower buckles 13. The length of the nylon tower buckle 13 is 550mm, and the rope mesh braided fabric has good flexibility, so that the width of an opened escape hole after the nylon tower buckle 13 is pulled open can reach 650mm, and the flexible sleeve 1 can be conveniently drilled by an evacuee to get on the boarding platform 3.

The utility model discloses a working process as follows, when withdrawing the system perpendicularly and receiving and releasing rope 5 through the hoist engine release, step on platform 3 and move down perpendicularly under the action of gravity of the balancing weight 4 of its below, aerify the shaping after falling to the sea until stepping on platform 3, the lower extreme is fixed and is expanded into straight cylindric at the flexible sleeve 1 of stepping on platform 3 this moment. The evacuated personnel enter the flexible sleeve 1 from the vacant sector area 211 of the first layer of supporting platform 2 through the upper platform and squat on the steel plate net 23 of the second layer of supporting platform 2, then fall down from the vacant sector area 211 of the second layer of supporting platform 2 to the steel plate net 23 of the next layer of supporting platform 2, and so on, the evacuated personnel sequentially pass through the vacant sector area 211 of each layer of supporting platform 2 and safely reach the boarding platform 3 at the bottom layer. Then the nylon tower buckle 13 is pulled open, and the evacuees can escape through the escape hole of the flexible sleeve 1 by taking a lifeboat.
