Description

Technical Field

[0001] The utility model relates to the technical field of cabins, in particular to a boat skeleton structure. Background Art

[0002] Law enforcement boats are important means of transport for anti-smuggling patrols and maritime law enforcement. Existing law enforcement boats generally have multiple cabins, including a cockpit, engine room, rest cabin, and bow tank. The engine room and bow tank are generally located at both ends of the law enforcement boat, and the other cabins are distributed between the two engine rooms and the bow tank.

[0003] For example, in a law enforcement boat provided in patent CN201510286375.3, the fuel tank and the dirty oil tank are both arranged in the cavity of an engine room together with the engine. Because the engine runs in the engine room for a long time, the temperature of the engine room will rise, causing the fuel to be in a greenhouse for a long time, accelerating the oxidation and deterioration of the oil. Therefore, a cabin structure is designed to ensure the storage environment of the fuel by adjusting the position of the fuel tank. Utility Model Content

[0004] The purpose of the utility model is to provide a boat skeleton structure, by arranging a first floor between the watertight bulkhead and the structural bulkhead, and arranging the fuel tank at the lower end of the first floor, that is, below the cockpit, thereby ensuring the storage temperature of the fuel tank and improving the storage environment.

[0005] The utility model provides the following technical solutions: a boat skeleton structure, comprising a bottom plate at the bottom of the cabin, one end of the bottom plate being connected to a stern closure plate layer, a side of the stern closure plate layer being connected to a partition plate, the partition plate being also connected to one end of the bottom plate, a plurality of solid ribs being distributed at intervals on the bottom plate, the solid ribs being connected to watertight bulkheads, structural bulkheads, collision bulkheads and ordinary bulkheads distributed in sequence from the stern to the bow, the side of the watertight bulkheads close to the stern forming an engine room with the bottom plate of the cabin, the watertight bulkheads and the structural bulkheads being connected to the engine room, A first floor is connected between the structural bulkheads, with its aft end connected to the side of the watertight bulkhead and its forward end connected to the upper end of the structural bulkhead. The cockpit is located above the first floor, and the fuel tank is located below the first floor. A second floor is also connected between the structural bulkhead and the collision bulkhead, with its aft end connected to the side of the structural bulkhead and its forward end connected to the side of the solid floor at the lower end of the collision bulkhead. The ordinary bulkhead is arranged at the lower end of the second floor.

[0006] Furthermore, the upper end of the stern closure plate layer is connected to a port reinforcement plate, and the port reinforcement plate is located in the cabin, and the connection strength between the upper end of the stern closure plate layer and the deck is enhanced by the port reinforcement plate.

[0007] Furthermore, side longitudinals are fixed on the side walls of the cabin, and the side longitudinals are distributed throughout the length. Side ribs are also fixed on the side walls of the cabin, and the side ribs are distributed perpendicular to the side longitudinals. The strength of the cabin side walls is enhanced by the side ribs and the side longitudinals.

[0008] Furthermore, a central inner keel is fixed in the middle of the bottom plate, and symmetrically distributed bottom longitudinals, symmetrically distributed main engine seat longitudinal girders and symmetrically distributed local girders under the pillars are fixed on both sides of the central inner keel. The bottom longitudinals are distributed throughout the length of the ship, and the main engine seat longitudinal girders and local girders under the pillars are distributed perpendicular to the solid ribs. The bottom longitudinals, main engine seat longitudinal girders and local girders under the pillars are used to enhance the rigidity and strength of the cabin bottom.

[0009] Furthermore, steel pipe supports are vertically fixed on the local trusses under the supports, and the supporting force of the first floor is improved by the steel pipe supports.

[0010] Furthermore, water pipes are provided in the cabin, and the water pipes are fixed on the side surfaces of the solid ribs and the side surfaces of the middle inner keel, so that the water demand of each cabin is met through the water pipes.

[0011] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0012] (1) By arranging a watertight bulkhead and a structural bulkhead, and arranging a first floor on the structural bulkhead, the space between the watertight bulkhead and the structural bulkhead is divided into two upper and lower areas. By arranging the fuel tank below the first floor, the fuel tank and the engine are separated, thereby reducing the storage temperature of the fuel tank;

[0013] (2) The first floor is located above the cockpit, and the fuel tank is placed below the cockpit. The temperature below the first floor is further lowered by the temperature of the cockpit to ensure the storage temperature of the fuel tank.

[0014] (3) The ordinary bulkhead is set close to the structural bulkhead, and the upper space of the second floor is divided into a toilet and a rest cabin by the ordinary bulkhead, so that the cockpit and the rest cabin are located on both sides of the toilet, making the space distribution more reasonable.
