AI Technical Summary
The buffer plates in the existing bulk carrier oil tanks cannot effectively adapt to changes in oil levels at different heights, which makes the oil tanks prone to deformation and damage under the impact of waves, and water hammer is easily generated when the oil fluctuates.
The system employs a guide column and corrugated plate structure. The corrugated plate moves with the oil level via a float ball, which drives the oil passage. Combined with antistatic materials or coatings, it buffers oil at different liquid levels. A water hammer eliminator is installed at the oil pump to prevent water hammer.
It achieves oil buffering at different liquid levels, protects the oil tank structure, avoids oil tank deformation and water hammer, and improves the safety and stability of fuel storage.

Abstract
Description
Technical fields:
[0001] This utility model relates to a fuel storage structure for bulk carriers. Background technology:
[0002] Bulk carrier is short for bulk cargo ship. It is a ship specifically used to transport unpackaged goods such as coal, ore, timber, livestock, and grain. Ships that transport bulk dry cargo such as grain, coal, ore, salt, and cement can be called dry bulk carriers, or simply bulk carriers.
[0003] Existing bulk carriers typically have fuel tanks in the engine room to store fuel oil. Bulk carriers usually have a long range and can carry hundreds or thousands of tons of fuel oil. As bulk carriers travel on the sea, they often encounter large waves, which can cause the fuel oil to impact the fuel tanks with tremendous force, leading to deformation and damage. Currently, some buffer plates are installed in the fuel tanks to cushion the impact of the fuel oil. However, these buffer plates are usually installed on the inner wall or bottom of the fuel tank. As the amount of fuel in the tank changes with the amount used, the fuel level in the tank is constantly changing. The buffer plates currently installed cannot effectively cushion the fuel oil at different levels. Summary of the Invention:
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to propose a fuel oil storage structure for bulk carriers. This fuel oil storage structure is reasonably designed and is conducive to buffering fuel at different liquid levels.
[0005] This utility model is implemented using the following solution.
[0006] The present invention relates to a fuel oil storage structure for bulk carriers, characterized in that: it includes a fuel oil storage tank and an output pipeline connected to the fuel oil storage tank, the output pipeline is equipped with an oil pump, the fuel oil storage tank is vertically provided with several guide columns, the guide columns are slidably connected with corrugated plates, the corrugated plates are provided with through holes for the guide columns to pass through, the lower surface of the corrugated plates is provided with a float corresponding to the position of the through hole, the guide column passes through the center of the float, and the corrugated plates are densely covered with oil passage holes.
[0007] Preferably, the guide post, corrugated plate, and float are made of antistatic material.
[0008] Preferably, the surfaces of the guide post, corrugated plate, and float are coated with an antistatic coating.
[0009] Preferably, a tee is installed at the output end of the oil pump on the above-mentioned output pipeline, and a water hammer eliminator is connected to one end of the tee.
[0010] Preferably, the float is in the shape of a circular tube, and the central channel of the circular tube float is fitted with the guide post with a clearance.
[0011] The working principle of this utility model's bulk carrier fuel storage structure is that the float in the fuel storage tank can float with the rise and fall of the oil level, so that the corrugated plate with oil passage holes can always be located above the oil level. When the hull is hit and rocked by the waves, the corrugated plate with oil passage holes can mitigate the fluctuation of the oil level, thus playing a buffering role. Therefore, this utility model's bulk carrier fuel storage structure can achieve a buffering effect on fuel at different liquid levels. Attached image description:
[0012] The present invention will be further described below with reference to the accompanying drawings;
[0013] Figure 1 This is a top view schematic diagram of the bulk carrier of this utility model;
[0014] Figure 2 This is a schematic diagram of the connection between the bulk carrier and the output pipeline;
[0015] Figure 3 This is a cross-sectional structural diagram of the fuel storage tank;
[0016] Figure 4 , 5 This is a schematic diagram of the cross-sectional structure of a fuel storage tank at different liquid levels. Detailed implementation method:
[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] This utility model relates to a fuel oil storage structure for bulk carriers, comprising a fuel oil storage tank 1 on a bulk carrier A and an output pipeline 2 connected to the fuel oil storage tank 1. The output pipeline 2 is equipped with a fuel oil pump 3, and a T-junction 9 is installed at the output end of the fuel oil pump. One end of the T-junction is connected to a water hammer eliminator 10. Since water hammer is easily generated at the moment of opening and closing of the fuel oil pump 3, which can easily damage the output pipeline, the installation of the T-junction 9 at the output end of the fuel oil pump and the connection of the water hammer eliminator 10 at one end of the T-junction helps to overcome the occurrence of water hammer.
[0019] Several guide posts 4 are vertically arranged inside the fuel storage tank 1. The guide posts 4 can be metal round rods. Corrugated plates 5 (which can be metal corrugated plates and connected to grounding wires) are slidably connected to the guide posts 4. Specifically, the corrugated plates 5 are provided with through holes 6 (which can be round holes) for the guide posts 4 to pass through. A float 7 is provided on the lower surface of the corrugated plates at the position corresponding to the through holes. The guide posts pass through the center of the float. The corrugated plates are densely covered with oil passage holes 8. The float 7 can be a metal float.
[0020] The specific float is in the shape of a circular tube. The central hole of the circular tube float is fitted with the guide column with a gap. As the oil level in the fuel storage tank 1 rises and falls, the float rises and falls accordingly, which in turn drives the corrugated plate 5 to rise and fall. When the hull is hit and rocked by the waves, the corrugated plate with oil passage holes can slow down the fluctuation of the oil level, thus playing a buffering role.
[0021] The guide posts, corrugated plates, and floats can also be made of other antistatic materials, or the surfaces of the guide posts, corrugated plates, and floats can be coated with an antistatic coating.
[0022] A cover plate 11 that can be opened and closed is provided on the upper part of the fuel storage tank 1, and fuel can be transferred into the fuel storage tank 1 by opening the cover plate 11.
[0023] This utility model of a fuel storage structure for bulk carriers can buffer fuel at different liquid levels and prevent water hammer in the output pipeline.
[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
