However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application.

[0027] The terms used in the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The singular forms "a", "said" and "the" used in the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein means and includes any or all possible combinations of one or more associated listed items.
[0028] In order to better understand the technical scheme of the present application, the present application will be described in detail below in combination with the drawings.
[0029] The utility model discloses a kind of LNG ship manifold area fire monitor, including the fire monitor operating platform 1 of being arranged in the side of manifold area, fire monitor 2 is arranged on fire monitor operating platform 1, the fire monitor 2 is connected with fire pipeline on LNG ship, fire monitor 2 and fire pipeline are all supported by fixed support 3, fixed support is fixed on fire monitor operating platform 1, the range of fire monitor 2 can cover farthest end manifold and nearest end manifold.
[0030] Specifically, one fire monitor operating platform 1 can be arranged in the bow and stern direction of manifold area 4 respectively, one fire monitor 2 is arranged on each horizontal operating platform 1, fire monitor 2 is connected with fire water pipe on LNG ship, in the embodiment, fire monitor 2 is connected with seawater fire pipe, fire monitor 2 and seawater fire pipe are all supported by fixed support 3, fixed support 3 is welded and fixed on fire monitor operating platform 1, fixed support can adopt any support frame body that can realize supporting effect. The fixed support for supporting fire monitor and the fixed support for supporting seawater fire pipe can be the same or different, for example, the fixed support for supporting fire monitor can be arranged as ordinary triangular support, and fire monitor is fixed on the top of triangular support; while the fixed support for supporting seawater fire pipe can be composed of triangular support and insulating pipe clamp fixed on the top of triangular support, and the insulating pipe clamp holds seawater fire pipe.
[0031] Preferably, in order to facilitate operator to quickly reach fire monitor operating platform 1, and facilitate quick evacuation in emergency, fire monitor operating platform 1 is arranged on one side of up and down inclined ladder of manifold platform 5, so that not only human factor engineering elements in fire emergency response can be fully considered, but also the safety and work efficiency of operator can be ensured. At the same time, fire monitor operating platform 1 is arranged on the side of ship side, close to manifold area 4, which can effectively avoid the equipment-intensive area existing in the inside of manifold area, reduce fire dead angle, so as to ensure that fire monitor can extinguish fire in manifold area 4 in the shortest time, greatly shorten the response time, improve the response efficiency in the early stage of fire, improve the rationality of overall layout, save valuable space resources of manifold area, and provide more flexibility for the arrangement of other equipment and pipelines.
[0032] Fire monitor operating platform 1 includes operating platform, platform fence arranged on both sides of operating platform, and anti-skid tread plate arranged between operating platform and ship deck. Operating platform is fixedly installed on the side deck of LNG ship, which should be able to bear the weight of fire monitor and operator, so as to ensure that operating platform can be stable and not shake in daily working state and non-working state. The specific structure of operating platform is similar to that of manifold platform, and both are composed of platform plate and support leg fixed on the bottom of platform plate. Platform plate is made of steel grating made of Q235A or Q235B angle steel. Since fire monitor operating platform is in open area and close to ship side, platform plate needs to be galvanized.
[0033] Preferably, an emergency escape route can also be set on the fire monitor operating platform 1 to ensure that operators can safely evacuate through the emergency escape route when the fire spreads out of control or other emergencies occur.
[0034] As described above, the fire monitor 2 is fixed to the platform plate of the fire monitor operating platform 1 by the fixed bracket 3. The arrangement position of the fire monitor 2 should be determined according to the actual size of the LNG ship manifold area, and taking into account that the fire monitor is arranged on the operating platform, there is a height difference between the fire monitor 2 and the manifold. Under normal working conditions, the water flow of the fire monitor is ejected in a parabolic trajectory. The maximum range of the fire monitor should be able to cover the farthest manifold (i.e., the jet of the fire monitor at the maximum elevation angle should be able to cover the farthest manifold), and the minimum range of the fire monitor 2 should be able to cover the nearest manifold (i.e., the jet of the fire monitor at the maximum depression angle should be able to cover the nearest manifold). Preferably, the range of the fire monitor 2 should be able to cover the entire manifold area and the area 1.5m in front of and behind it.
[0035] In this embodiment, the maximum elevation angle of the fire monitor 2 is 30°, and the left and right rotation range of the fire monitor is 60°.
[0036] To ensure that the parabolic jet range of fire monitor 2 can fully cover all manifolds in manifold area 4, a certain height difference can be set between fire monitor operating platform 1 and manifold platform 5, meaning the platform height of fire monitor operating platform 1 is higher than that of manifold platform 5. By setting a height difference between fire monitor operating platform 1 and manifold platform 5, not only can the range requirement be met, but the utilization rate of the fire water system can also be improved.
[0037] Preferably, since different height differences affect the spray angle and range of the water flow, to adapt to complex environments and enhance fire extinguishing effects, the platform height of the fire monitor operating platform 1 is 4.6m-5.4m higher than that of the manifold platform 5 in the manifold area. This allows the water jet from the fire monitor to better penetrate the flame layer and directly act on the root of the fire source, enhancing the fire extinguishing effect. Simultaneously, this design also considers the dynamic changes of the LNG ship during navigation, ensuring that the water monitor maintains stable fire extinguishing performance under different operating conditions. Furthermore, this design allows operators operating the water monitor on the platform to clearly observe changes in the fire situation in the manifold area, enabling more accurate judgments and decisions. In addition, the height difference reduces the risk of operators being directly exposed to the fire source, improving safety during operations.
[0038] The aforementioned fire monitor is either a water fire monitor or a dry powder fire monitor. When the fire monitor is a water fire monitor, it is connected to the seawater fire-fighting pipe on the LNG ship; when the fire monitor is a dry powder fire monitor, it is connected to the dry powder fire-fighting pipe on the LNG ship.
[0039] It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
