Description

Technical Field

[0001] The utility model belongs to the technical field of ship parts, and more specifically, relates to a ship ventilation pipeline structure. Background Art

[0002] Vessels require ventilation structures, which typically include vent pipes and vent heads. Existing vent structures rely on natural ventilation beneath the vent heads, resulting in poor air flow and poor ventilation. Furthermore, existing structures pose concerns about water ingress into the vent heads during rough seas and rivers.

[0003] The prior art includes a technology entitled "Marine Oil Tank Vent Pipe Head Oil Collecting Device and Ship" and publication number "CN118083034A." This technology relates to the field of ships, and more particularly, to a marine oil tank vent pipe head oil collecting device and ship. The marine oil tank vent pipe head oil collecting device comprises: an oil collecting member forming an oil collecting cavity into which a vent pipe extends, and an outer wall of the oil collecting member forming an opening for the vent pipe to extend out of the oil collecting cavity; the oil collecting member comprises a first shell and a second shell, each of which surrounds a portion of the side wall of the vent pipe. The first and second shells are joined to form the oil collecting cavity and cover the entire circumference of the vent pipe; the first and second shells are connected by non-welding; and a sealing assembly is sandwiched between the first and second shells and between the oil collecting member and the wall of the vent pipe. The oil collecting device of the present invention is formed into a two-part structure that is butted together on both sides of the vent pipe in the radial direction. This allows for the non-welding installation of the oil collecting device and the vent pipe head, thereby meeting the need to install the oil collecting device in the oil tank after refueling, thereby improving the fault tolerance during the ship production process and enhancing ship production efficiency. However, this technology does not address the technical problems and technical solutions of the present application. Utility Model Content

[0015] The technical solution of this utility model is adopted, and the working principle and beneficial effects are as follows:

[0016] The present invention relates to a ship ventilation pipe structure. When the structure is configured, a ventilation pipe and a ventilation head are separately formed. The ventilation pipe is a long tube that can be straight or curved and can be positioned according to the position of the component to be ventilated. The lower end of the ventilation pipe is connected to the component to be ventilated, used to connect the component to the outside and the ventilation head.

On the other hand, the reinforcement component is located below the ventilation head, which plays a role in shielding wind and waves. When wind and waves contact the air circulation holes at the bottom of the ventilation head, they are blocked by the reinforcement structure, which has the effect of blocking wind and waves, preventing a large amount of wind and waves from entering the interior of the ventilation head through the air circulation holes, and reducing the impact of wind and waves on the ventilation head.

[0022] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.

[0023] As attached Figure 1 -Attached Figure 3As shown, the present invention is a ship ventilation piping structure. The lower end of the ventilation pipe 1 is connected to the component 2 requiring ventilation. The upper end of the ventilation pipe 1 is connected to the ventilation head 3. The lower portion of the ventilation head 3 is provided with air circulation holes 4. A reinforcement component 5 is mounted on the outer ring of the ventilation pipe 1 below the ventilation head 3. The reinforcement component 5 is provided with a reinforcement slope 6. The above structure addresses the shortcomings of the existing technology and provides an improved technical solution. When setting up the structure, the ventilation pipe 1 and the ventilation head 2 are separately manufactured. The ventilation pipe 1 is a long tube and can be straight or curved, depending on the position of the component 2 requiring ventilation connected to the ventilation pipe. The lower end of the ventilation tube 1 is connected to the component 2 requiring ventilation, and is used to achieve communication between the component 2 requiring ventilation and the outside, and to achieve communication between the component 2 requiring ventilation and the ventilation head 3. The gas inside the component 2 requiring ventilation flows through the ventilation tube 1 to the ventilation head 3, and then flows to the outside through the ventilation head 3. The upper end of the ventilation tube 1 is connected to the ventilation head 3, and the ventilation head 3 is provided with an air circulation hole 4 at the bottom. A reinforcement component 5 is installed on the outer ring of the ventilation tube 1 below the ventilation head 3, and the reinforcement component 5 is provided with a reinforcement slope 6. After the reinforcement component 5 is provided, on the one hand, when the wind flows below the ventilation head 3, it first acts on the reinforcement slope 6. Then, under the resistance and guiding effect of the reinforcement slope 6, the flow direction of the wind is changed to upward, and then enters the interior of the ventilation head 3 through the air circulation hole 4, thereby strengthening the air flow, which can accelerate the speed at which the gas inside the ventilation head 3 flows to the outside, and improve the ventilation effect. On the other hand, the reinforcement member 5 is located below the vent head 3, providing a shield against wind and waves. When wind and waves contact the air circulation holes 4 below the vent head, they are blocked by the reinforcement structure 5, effectively blocking the wind and waves and preventing a large amount of wind and waves from entering the vent head 3 through the air circulation holes 4, thereby reducing the impact of wind and waves on the vent head. The ship ventilation pipe structure described in the utility model has a simple structure, effectively improves the ventilation effect, and at the same time reduces the impact of wind and waves on the vent head to a certain extent, reduces water ingress, and improves operational reliability.

[0024] The reinforcing member 5 is a circular ring structure. An annular reinforcing slope 6 is provided along its upper surface, forming an acute angle with the lower surface of the vent head 3. With this structure, the reinforcing member, through the reinforcing slope, guides the wind below the vent head 3. As wind flows below the vent head 3, it first acts on the reinforcing slope 6. Then, under the resistance and guidance of the reinforcing slope 6, the wind changes its direction upward and enters the vent head 3 through the air circulation holes 4, strengthening the air flow. This accelerates the flow of gas from the vent head 3 to the outside, improving the ventilation effect. The reinforcing member also serves to block wind and waves.

[0025] The air circulation holes 4 at the bottom of the ventilation head 3 are arranged in a plurality of shapes, and the plurality of air circulation holes 4 are arranged in a ring structure along the outer circle of the ventilation tube 1. In the above structure, each air circulation hole can enter the air, and the wind entering from the air circulation hole can promote the air flow in the ventilation head.

[0026] The reinforcing member 5 has a central hole 7 at its center. The reinforcing member 5 is then fitted onto the outer ring of the vent tube 1 through the central hole 7 and welded to the vent tube 1. In this structure, the reinforcing member is fitted onto the vent tube through the central hole, and the two are welded to secure the structure. The reinforcing member is positioned below the vent head, but the distance from the vent head should be limited, as this will compromise the effectiveness of the structure.

[0027] The component 2 requiring ventilation is a ship's oil tank, a ship's cargo hold, or a ship's passenger cabin.

[0028] The vent head 3 is cylindrical in structure, with an open top. A lower plate 8 is positioned below the vent head 3, with air holes 4 formed in the lower plate 8. The upper end of the vent tube 1 extends through the lower plate 8 into the interior of the vent head 3. In this structure, the vent tube and the lower pipe are welded together, providing a secure connection and reliable drainage of gas from the component requiring ventilation.

[0029] The ventilation tube 1, the ventilation head 3 and the reinforcement member 5 are made of metal materials. The metal material has high strength, and the surface of the components is sprayed with anti-rust paint to increase the service life.

[0030] The diameter of the horizontal cross section of the ventilation head 3 is larger than the diameter of the ventilation tube 1 .

[0031] The ship ventilation pipeline structure described in the present invention comprises a ventilation pipe 1 and a ventilation head 2. The ventilation pipe 1 is a long tube that can be straight or curved, and is positioned according to the position of the ventilation component 2 to be connected to the ventilation pipe. The lower end of the ventilation pipe 1 is connected to the ventilation component 2, used to connect the ventilation component 2 with the outside and connect the ventilation component 2 with the ventilation head 3. The gas inside the ventilation component 2 flows through the ventilation pipe 1 to the ventilation head 3, and then flows to the outside through the ventilation head 3. The upper end of the ventilation pipe 1 is connected to the ventilation head 3, and the lower portion of the ventilation head 3 is provided with an air circulation hole 4. A reinforcement component 5 is installed on the outer ring of the ventilation pipe 1 below the ventilation head 3, and the reinforcement component 5 is provided with a reinforcement slope 6. After the reinforcement member 5 is installed, wind flowing below the ventilation head 3 first acts on the reinforcement bevel 6. The wind then changes its direction upwards due to the resistance and guidance of the reinforcement bevel 6, and then enters the ventilation head 3 through the air circulation holes 4, strengthening the air flow. This accelerates the flow of gas from the ventilation head 3 to the outside, improving ventilation. Furthermore, the reinforcement member 5, located below the ventilation head 3, acts as a shield against wind and waves. When wind and waves contact the air circulation holes 4 below the ventilation head, they are blocked by the reinforcement member 5, effectively blocking the wind and waves, preventing large amounts of wind and waves from entering the ventilation head 3 through the air circulation holes 4, and reducing the impact of wind and waves on the ventilation head.

[0032] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
