Description

Technical Field

[0001] This utility model relates to the field of shipbuilding, and in particular to a multifunctional propeller structure. Background Technology

[0002] In ship propulsion systems, traditional hull shafts are typically quite long to meet the power transmission requirements of navigation. When rotating at high speeds under engine drive, their large length-to-diameter ratio and insufficient rigidity greatly increase the probability of vibration. This vibration continuously generates irregular stress on the seals that mate with the mast, accelerating their wear and damage. During mast rotation, high-speed friction between the bearing housing and the mast generates a large amount of heat. Traditional structures lack effective cooling methods, leading to continuous heat accumulation. This not only causes performance degradation in bearings and mast components due to high temperatures but also further accelerates the aging of the seals, shortening their lifespan. As a critical sealing component between the hull and the mast, damage to the seals allows external water to overflow directly into the cabin. However, traditional structures lack any warning devices, making it difficult for crew members to accurately assess when seal damage occurs. Often, the fault is only noticed after significant water ingress, which not only damages equipment inside the cabin but also significantly increases the difficulty and cost of maintenance and replacement, seriously threatening the ship's navigational safety. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional paddle structure that has a cooling effect and can indicate leaks.

[0004] The purpose of this utility model is achieved as follows: a multifunctional propeller structure includes an engine compartment, an engine housed within the engine compartment, a cooling water tank extending outward from the outer side of the engine compartment, a rotating shaft extending outward from the engine, the other end of the rotating shaft passing through the engine compartment and the cooling water tank and connected to a propeller, the rotating shaft being connected to the cooling water tank wall and the engine compartment wall via a bushing; a partition is provided at the top of the cooling water tank, a conical through hole extending downward from the center of the partition, the cooling water tank below the conical through hole being filled with cooling water, and a level gauge being provided above the partition.

[0005] Preferably, the bushing and the rotating shaft are provided with a bearing, a sealing ring, a support ring, and a bearing in sequence from left to right.

[0006] Preferably, the partition plate is inclined towards the conical through hole at the center, forming a conical structure.

[0007] Preferably, a maintenance door is provided on the bulkhead between the cooling water tank and the engine compartment, and the outer ring of the maintenance door is in sealed contact with the bulkhead; the cooling water is filled below the maintenance door.

[0008] Compared with the prior art, the advantages of this utility model are:

[0009] 1. When the bearing seal on the outer side of the cooling water tank leaks, water enters the cooling water tank, and the level gauge detects this and triggers an early warning. If the bearing seal between the cooling water tank and the engine room malfunctions, water leakage from the engine room can also be detected promptly. This dual early warning mechanism allows shipboard personnel to quickly determine the location of the fault and perform repairs. Furthermore, the limited cooling water volume in the cooling water tank prevents large-scale water leakage, significantly improving the safety of ship operations.

[0010] 2. Cooling water can cool the bearing area. Combined with the bushing design connecting the two sets of bearings, it can effectively reduce the vibration of the shaft during operation, ensure stable operation of the shaft, and thus ensure the propeller and the entire power system to work efficiently for a long time. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] The components include: 1. Engine compartment; 2. Engine; 3. Cooling water tank; 4. Shaft; 5. Propeller; 6. Shaft sleeve; 7. Bulkhead; 701. Conical through hole; 8. Level gauge; and 9. Maintenance door. Detailed Implementation

[0013] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0014] It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. These terms are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. The terms "horizontal," "vertical," and "suspended," etc., do not indicate that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0015] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1 As shown, a multi-functional propeller structure includes an engine compartment 1, an engine 2 housed within the engine compartment 1, a cooling water tank 3 extending outward from the outer side of the engine compartment 1, a shaft 4 extending outward from the engine 2, the other end of the shaft 4 passing through the engine compartment 1 and the cooling water tank 3 and connected to a propeller 5, the shaft 4 being connected to the walls of the cooling water tank 3 and the engine compartment 1 via a bushing 6; a partition 7 is provided at the top of the cooling water tank 3, a conical through hole 701 extending downward from the center of the partition 7, the cooling water tank 3 below the conical through hole 701 being filled with cooling water, a level gauge 8 is provided above the partition 7, and the level gauge is connected to an external alarm system to provide early warning; during design and installation, the level gauge is located in the central axis area of ​​the hull.

[0017] like Figure 1 As shown, from left to right, the bushing 6 and the rotating shaft 4 are provided with a bearing, a sealing ring, a support ring, and another bearing, providing two sets of bearing connections to ensure the stability of the rotating shaft's operation and reduce vibration.

[0018] like Figure 1 As shown, the bulkhead 7 is inclined towards the conical through-hole 701 at the center, forming a conical structure. When the ship is floating, it can quickly guide the cooling water that surges up under the bulkhead down, avoiding prolonged stagnation.

[0019] like Figure 1 As shown, a maintenance door 9 is provided on the bulkhead between the cooling water tank 3 and the engine compartment 4. The outer ring of the maintenance door 9 is sealed against the bulkhead, and the maintenance door is installed below the bulkhead. Cooling water is filled below the maintenance door. The maintenance door facilitates maintenance personnel to maintain the internal bulkhead or bushings, while limiting the height of the cooling water to prevent the maintenance door from being in constant contact with the cooling water and reduce leakage.

[0020] The working principle of this utility model is explained as follows: When a leak occurs on the outside of the cooling water tank, water will enter the cooling water tank until the level gauge detects an alarm. The ship's crew can quickly determine that there is a problem with the outer bearing seal and perform rapid maintenance. When there is a problem with the bearing seal between the cooling water tank and the engine room, water will leak into the engine room. The ship's crew can also quickly maintain the bearings inside the engine room. The amount of cooling water in the cooling water tank is limited, so there will be no large-scale internal leakage. The dual warning system greatly improves safety. At the same time, the cooling water can cool the bearings, ensuring their long-term operation.

[0021] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
