Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and more particularly to the field of water flow hole technology at the hull intake, specifically referring to a rib structure at the intake. Background Technology

[0002] Ribs, constructed from a single piece of steel, are distributed transversely perpendicular to the midsole girder and are important components in the hull structure used to increase rigidity and stability. Due to the complex fluid flow at the ship's intake, flow holes are usually provided on the ribs at the intake to guide the fluid more smoothly through the rib area, reducing stagnation and eddy effects behind the ribs.

[0003] like Figure 1 and Figure 2 As shown, the existing arrangement of drainage holes is not only limited by space, but also needs to consider the distance between the drainage holes and the longitudinal stiffener through holes, as well as the distance between the drainage holes and the welds, resulting in difficulties in drainage hole arrangement. In order to ensure the strength of the ribs, the existing drainage holes are mostly opened in a circular or fan-shaped structure, and the drainage holes need to be opened between two adjacent vertical stiffeners, resulting in a small opening area for the drainage holes and incomplete drainage.

[0004] Therefore, there is a need for a rib structure at the suction port that can increase the drainage area of ​​the water flow hole while ensuring the strength of the rib, so that the fluid can pass through more smoothly. Summary of the Invention

[0005] The main objective of this invention is to provide a rib structure at the suction port to solve the problem of incomplete drainage caused by insufficient water flow hole area at the suction port in the prior art.

[0006] To achieve the above objectives, the present invention provides a rib plate structure at the suction port, including a rib plate body, on which a plurality of vertical stiffeners are uniformly arranged, and longitudinal ribs penetrate through the bottom of the rib plate body corresponding to the positions of each vertical stiffener. The rib plate between two adjacent longitudinal ribs at the suction port is removed, forming a square hole as a drainage hole.

[0007] Furthermore, on the rib plate body, a reinforcing rib is provided horizontally above the water flow hole.

[0008] Furthermore, the reinforcing ribs are placed between the two vertical reinforcing members on both sides of the water flow hole.

[0009] Furthermore, the distance between the reinforcing rib and the upper sidewall of the drainage hole is 15 mm.

[0010] Furthermore, at least one side of the two sidewalls of the water outlet is provided with a reinforcing patch that matches the corresponding longitudinal bone.

[0011] Furthermore, the reinforcement plate is a square plate, and the two apex corners on the plate that connect to the rib plate are chamfered.

[0012] Furthermore, the length of the water outlet is 940 mm and the width of the water outlet is 395 mm.

[0013] Furthermore, the two longitudinal bones corresponding to the two sides of the water flow hole are located inside the water flow hole.

[0014] Furthermore, the rib plate itself is a single piece of metal.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention eliminates the suction port and requires the creation of ribs between the two longitudinal ribs on either side of the water outlet location, increasing the opening area of ​​the water outlet and making the fluid flow more smoothly, thus solving the problem of incomplete drainage caused by the small water outlet area. This invention addresses the design of square drainage holes by adding reinforcing ribs and reinforcing plates at the edges of the drainage holes through a reasonable connection method. This strengthens the ribs at the drainage holes, solving the problem of incomplete drainage while ensuring the strength of the ribs. Attached Figure Description

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 3 The diagram illustrates a rib structure at a suction inlet, comprising a rib body 1 with several vertical stiffeners 2 evenly distributed on it. A longitudinal rib 3 penetrates the bottom of the rib body 1 corresponding to the positions of each vertical stiffener 2. The ribs between adjacent longitudinal ribs 3 at the suction inlet are removed, forming square holes as drainage holes 4. The suction inlet of a ship typically refers to the opening structure on the bottom or side of the ship used for drawing in liquid. The rib is usually constructed from a single piece of steel. Due to the complex fluid flow at the suction inlet, drainage holes 4 are typically provided on the rib to meet the fluid flow requirements. The size and number of drainage holes 4 need to be calculated based on the flow rate at the suction inlet. By removing the ribs between adjacent longitudinal ribs 3 at the suction inlet, the area of ​​the drainage holes 4 is increased, reducing or avoiding the problem of incomplete drainage caused by a small drainage hole area. The rib, as a transverse strong member of the ship, bears transverse strength and prevents structural torsional deformation. The longitudinal ribs 3, as longitudinal strong members, bear total longitudinal bending strength and prevent longitudinal buckling of the structure. The longitudinal bone 3 needs to pass through the rib plate to avoid interruption. This is achieved by making an incision in the rib plate to allow the longitudinal bone 3 to pass through, and welding one side of the web of the bone to the rib plate.

[0023] Specifically, a reinforcing rib 5 is provided horizontally above the water outlet hole 4 on the rib body 1. By providing the reinforcing rib 5 above the water outlet hole 4, the strength of the rib at the suction port is increased, and the impact of enlarging the water outlet hole 4 on the strength of the rib is reduced.

[0024] Specifically, the reinforcing ribs 5 are positioned between the two vertical stiffeners 2 on either side of the drainage hole 4. The location and number of the reinforcing ribs 5 are related to the dimensions of the drainage hole 4.

[0025] Specifically, the distance between the reinforcing rib 5 and the upper wall of the drainage hole 4 is 15 mm.

[0026] Specifically, at least one side of the two side walls of the water outlet 4 is provided with a reinforcing plate 6 that matches the corresponding longitudinal bone 3.

[0027] Specifically, the reinforcing plate 6 is a square plate, with chamfered corners at the two apex where it connects to the rib. Chamfering refers to the machining process of cutting the edges of the workpiece into a certain bevel. The reinforcing plate 6 is usually welded onto the rib. By setting the chamfer, the edge burrs of the reinforcing plate 6 can be reduced, avoiding porosity or slag inclusions during welding.

[0028] Specifically, the length a of the drainage hole 4 is 940 mm, and the width b of the drainage hole 4 is 395 mm. The width of the drainage hole 4 is greater than or equal to the height of the longitudinal bone 3, and the length of the drainage hole 4 is greater than or equal to the distance between two adjacent longitudinal bones 3.

[0029] Specifically, the two longitudinal bones 3 on both sides of the water outlet 4 are located inside the water outlet 4.

[0030] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
