Technical Field

[0001] This utility model relates to the field of ship technology, and in particular to an emergency release mechanism for dangerous goods on passenger and cargo ships. Background Technology

[0002] With economic development, the trade in flammable, explosive, and other hazardous materials is increasing. Maritime transport, characterized by its economy, safety, and large capacity, is one of the main routes for transporting hazardous materials. Ships carrying oil, hazardous chemicals, and other dangerous goods are at risk of serious damage to the vessel and significant casualties in the event of a fire, explosion, or major leak. Ensuring safety during the transport of hazardous materials is paramount in ship design. For vessels carrying hazardous materials, it is necessary to prevent potential hazards during loading, reduce the risk of accidents, minimize damage in the event of an accident, and facilitate loading, unloading, and routine maintenance for the shipowner. For ships with limited space, there may not be enough room specifically for hazardous materials containers; therefore, innovative designs are needed to utilize the limited space on board.

[0003] Existing dangerous goods containers are generally transported by container ships; currently, there are no passenger ships carrying dangerous goods containers.

[0004] However, in certain special circumstances, passenger ships need to carry dangerous goods containers. In this case, the dangerous goods containers are usually placed on the container platform and cannot be thrown off the hull. In the event of a fire, explosion, or major leak, it may lead to serious damage to the ship and major casualties, especially for passenger ships carrying a large number of passengers.

[0025] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a dangerous goods emergency release mechanism for a passenger container ship includes an upper platform 10 for securing dangerous goods containers and a lower platform 20 located below the upper platform. The lower platform 20 has a height of not less than 2 meters. Both the upper and lower platforms are steel structures.

[0027] The lower platform 20 is fixed to the deck 40 of the passenger / cargo ship. The deck is an open deck. The deck can be a mooring deck at the bow of the ship. The lower platform is located on the side of the deck. The lower platform is fixed to the bulwark 41.

[0028] A sloping slide rail 21 is fixedly installed at the top of the lower platform. The slide rail 21 extends sloping downwards towards the outwards of the hull. The inclination angle of the slide rail is not less than 7°.

[0029] The bottom of the upper platform is provided with a pulley 11 that can be adapted to the slide rail; the pulley 11 is located on the slide rail 21.

[0030] A limiting component 30 is provided between the upper platform 10 and the lower platform 20 to restrict the movement of the upper platform.

[0031] The top of the upper platform is equipped with container fasteners 12 for securing dangerous goods containers. Dangerous goods containers 13 are secured to the top of the upper platform. The container fasteners are standard container legs.

[0032] The emergency release mechanism for dangerous goods on passenger and container ships also includes a remotely controlled release device 31 that can release the limit component from its limit position.

[0033] The remote control operation release device 31 is connected to the limit component 30. The remote control operation release device 31 and the limit component 30 are connected by a control line.

[0034] Remote control operation release devices and limit components can take many forms. Since both are common existing components, they will not be described in detail here.

[0035] The emergency release mechanism for dangerous goods on passenger / cargo ships in this plan is located on the open deck side for easy and rapid disposal. In practical application, it should be positioned as far away as possible from passenger and crew accommodation areas to minimize safety risks to passengers and crew. Figure 7 As shown, the emergency release mechanism 50 for dangerous goods on passenger and container ships is located in the mooring area 51 at the bow of the ship, without affecting the mooring operations of the crew.

[0036] The main structure of the dangerous goods emergency release mechanism on passenger / cargo ships consists of an upper platform and a lower platform. The upper platform is equipped with pulleys at its bottom, and the lower platform has rails with an inclination angle of up to 8 degrees. The upper and lower platforms are connected by pulleys and rails. The upper platform is always ready for release, controlled by a limiting component that can be remotely operated to release the container. Once crew members detect a hazard, they can remotely operate the release device to release the limiting component. Under gravity, the upper platform, carrying the dangerous goods container, automatically slides outwards towards the side of the ship, releasing both the upper platform and the dangerous goods container overboard. Figure 3 , Figure 4 , Figure 5 , Figure 6 The diagram shows the upper platform sliding outwards towards the side of the hull.

[0037] Standard container legs are fixed on the upper platform. The crew can use a crane to lift the standard container to the dock. After the container is loaded with dangerous goods, it is lifted by a crane to the upper platform and fixed to the container legs on the upper platform by automatic twist locks. During unloading, the container is also lifted by a crane to the dock for unloading dangerous goods.

[0038] The emergency release mechanism for dangerous goods on passenger / cargo ships is located on the ship's side, while the remotely controlled release device needs to be positioned away from the dangerous goods containers. The lower platform is over 2 meters high, allowing crew members easy access for mooring operations. The entire release mechanism is easily visible to the crew for routine maintenance.

[0039] This invention can significantly reduce the hazards posed by the loading of dangerous goods to the safety of ships and personnel on board, and has the following advantages:

[0040] 1. For passenger and container ships, which carry both passengers and containers, it is necessary to ensure the safety of passengers. This utility model can remove dangerous goods away from the ship as quickly as possible and dump them into the sea, thus protecting the safety of the ship and its crew to the greatest extent.

[0041] 2. The mechanism of this utility model can be released quickly and can be released remotely when the crew discovers danger, without the need for the crew to operate it at close range, thus reducing the danger to the crew.

[0042] 3. The release mechanism of this utility model is ingeniously designed to automatically release dangerous goods by gravity. Only by operating the remote control release device, the lower platform can automatically slide away from the side of the ship under the action of gravity with the dangerous goods, without the need for additional power, thus reducing the complexity of the mechanism.

[0043] 4. The structure of this utility model is compact. Containers containing dangerous goods can be stacked on the upper platform using standard container legs and twist locks. Ship owners can easily load and unload dangerous goods using cranes.

[0044] 5. The mechanism of this utility model integrates the release mechanism with the ship's hull structure and mooring operation space, which not only meets the need for rapid release of dangerous goods containers, but also leaves sufficient space for crew members to perform mooring operations under the platform. At the same time, the structural design of the release mechanism is combined with the ship's bulwark structure, making the entire structure more reasonable.

[0045] 6. The mechanism of this utility model has the advantage of convenient maintenance. All the structures and devices of this mechanism can be maintained at close range, ensuring the safety of maintenance personnel.

[0046] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
