Abstract

The utility model discloses a stem structure of a ro-ro passenger ship. Another bow inner door is arranged on the inner side of a bow outer door and is hinged on one side of a bulkhead in an openable and closable mode, water sealing materials are arranged on the periphery of the bow inner door, and when the bow inner door is closed, the water sealing materials on the periphery of the bow inner door and the bulkhead are tightly pressed to form a water sealing structure. The bow inner door is closed, the water sealing materials on the periphery of the bow inner door and the bulkhead are abutted tightly, and the water sealing structure is formed. Even sea waves entering through the bow outer door can not further enter a deck of the bulkhead through the bow inner door, and therefore requirements for the height of a stem are reduced. In addition, due to the protection of the bow inner door, one or more than one layers of bottom roll-shipment locations can be divided out at a position of a void cabin below a deck of a vehicle, and therefore space utilization efficiency of a cabin can be improved to a large extent, and the area and loading amount of the roll-shipment locations are improved.

Description

A kind of bow construction of ro-ro passenger ship

Technical field

The present invention relates to the bow construction of ro-ro passenger ship.

Background technology

The forward perpendicular place of ro-ro passenger ship is Zi being called as bow height corresponding to the waterline amount of appraising and deciding summer freeboard and designed drag to the vertical distance of shipboard weather deck top.In order to guarantee in ro-ro passenger ship navigation process, vehicle safety on its deck, avoid wave to enter the deck by the bow external door and flood vehicle and goods, cause damage, maritime office " internal navigation Technical Regulation for Statutory Survey of Seagoing Ships " has stipulated the bow height requirement of the minimum of Coastal Navigation Areas III level ro-ro passenger ship.Yet bow height is larger, and the bottom-to-top-height of boats and ships is larger, and the center of gravity of boats and ships is also higher, and the stability of its navigation is relative with safety just poorer." internal navigation Technical Regulation for Statutory Survey of Seagoing Ships " also stipulated, the width average of only establishing one deck car deck and being provided with first ramp door, the every side of a ship deck house of stem as full ship is not less than 0.2B and is not less than 0.07L and highly is not less than the superstructure calibrated altitude from the length that fore perpendicular measures backward, can exempt the requirement to bow height, this regulation is called as the exemption condition to minimum bow height.In order to satisfy the exemption condition to minimum bow height, most of domestic ro-ro passenger ships have all adopted above-mentioned form of only establishing one deck car deck on the bulkhead deck.Yet the ro-ro passenger ship of this form exists again the cabin space availability ratio low, rolls dress place area little, the problem that the loading of freight waggon is low.

Summary of the invention

The present invention is intended to overcome the problem of above-mentioned prior art, provide a kind of can be when bulkhead arranges the Multi-layer vehicles deck, can satisfy again bow height and exempt the bow construction of the ro-ro passenger ship of condition, with when adopting less bow height, improve the degree of utilization in cabin space.

The bow construction of ro-ro passenger ship described in the utility model, the bow front end arranges the bow external door, the hatch place of the leading section of the vehicle hold of bow external door inboard has set up the bow inside door one, the inboard of its bow external door is provided with another road bow inside door, a described bow inside door side that is hinged on bulkhead to be opened/closed, the surrounding of bow inside door is provided with the water-stop material, and when closed, the water-stop material of bow inside door surrounding and bulkhead compress and form watertight structure.

The bow construction of ro-ro passenger ship described in the utility model, bow arranged outside bow external door, the inboard of bow external door, hatch place at the leading section of vehicle hold has set up the bow inside door one, bow inside door surrounding arranges the water-stop material, when vehicle entered, the bow inside door can be opened the side at bulkhead, formed unimpeded passage on the deck.Vehicle enter complete after, the bow inside door is closed, leakproofing material and the bulkhead of its surrounding offset, and form watertight structure.Even the wave by the bow external door enters also can't enter in vehicle hold by the bow inside door again, thereby it has reduced the requirement of bow height.In addition, protection due to the bow inside door, even entering into the wave of car deck top in the bow external door also can't enter on car deck by the bow inside door, therefore, its place, empty cabin below car deck can arrange the above car deck of one deck again, fills the place as extra rolling, thereby significantly promote the degree of utilization in cabin space, improve and roll dress place area and the loading of freight waggon.Can arrange between each layer car deck

The bow construction schematic diagram of a kind of ro-ro passenger ship of Fig. 1;

Fig. 2 is the birds-eye view of Fig. 1;

Fig. 3 is bow inside door open mode schematic diagram.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, the leading section of the bow of ro-ro passenger ship 1 is provided with bow external door 2, vehicle hold front port 3 places of the inboard of bow external door are provided with another road bow inside door 4, the bow inside door is hinged on a side of bulkhead by rotating shaft, the surrounding of bow inside door is provided with water-stop material 4, when the bow inside door was closed, the water-stop material of its surrounding and bulkhead surrounding compressed and form watertight structure.

Bow inside door 4 can be hinged on the upside of bulkhead, on the deck of bulkhead downside, hydraulic actuating cylinder is installed, by the switching of Driven by Hydraulic Cylinder bow inside door.Or the bow inside door also can be hinged on the downside of bulkhead, on the deck of bulkhead upside, hydraulic actuating cylinder is installed, by the switching of Driven by Hydraulic Cylinder bow inside door.

The bow inside door also can be hinged on left side or the right side of bulkhead.

Described bow inside door can with the springboard one, as Fig. 3.

The water-stop material of bow inside door surrounding can be the good leakproofing materials of watertightness performance such as silica gel.

Claims

1. the bow construction of a ro-ro passenger ship, the bow front end arranges the bow external door, it is characterized in that: the hatch place of the leading section of the vehicle hold of bow external door inboard has set up the bow inside door one, a described bow inside door side that is hinged on bulkhead to be opened/closed, the surrounding of bow inside door is provided with the water-stop material, and when closed, the water-stop material of bow inside door surrounding and bulkhead compress and form watertight structure.

2. the bow construction of ro-ro passenger ship according to claim 1, it is characterized in that: the bow inside door is hinged on the upside of bulkhead, on the deck of bulkhead downside, hydraulic actuating cylinder is installed, by the switching of Driven by Hydraulic Cylinder bow inside door.
