Description

Technical Field

[0001] The invention relates to a ship-used shaft generator anti-sway fixing device, which belongs to the technical field of ship design. Background Art

[0002] As the carbon emission standards of the shipping industry become increasingly higher, the use of shaft generators by ships to reduce carbon emissions to meet relevant environmental protection requirements is becoming more and more popular on large ships. However, the area where the shaft generator is installed is near the main engine and main shaft at the bottom of the ship's engine room. The environment in the relevant area has large vibration and shaking. At the same time, the shaft generator body also vibrates and shakes during operation. Combining the two, the vibration and shaking problems must be considered when installing the shaft generator. At this stage, when major shipyards install shaft generators, they mainly improve the strength of the auxiliary machine body and its bottom hull structure to reduce the vibration and shaking of the shaft generator. However, when the equipment itself is relatively high or the vibration itself is large, the effect is limited and not economical.

[0003] The shaft generators commonly used nowadays are generally not equipped with anti-roll bars. The vibration and shaking of the equipment are reduced only by increasing the specifications of the auxiliary machine platform at the bottom and the hull structure. This is not economical and the effect is not ideal. Taking into account the limitations of the shaft generator itself, its surrounding environment, and pipelines, most of them adopt the form of adding hard connections between the various components of the shaft generator body, but the effect is not ideal. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a marine shaft generator anti-sway fixing device to safely remotely operate and adjust the radar scanner, adapt to all-weather weather and facilitate personnel operation.

[0005] The technical means adopted by the present invention are as follows: a ship-used shaft generator anti-sway fixing device, a plurality of anti-sway fixing devices are arranged on the shaft generator, the anti-sway fixing device comprises a shaft generator body connection mechanism and an anti-sway body, the shaft generator body screw and the shaft generator body fixing plate in the shaft generator body connection mechanism are T-shaped welded, the end of the anti-sway body and the anti-sway body fixing plate are T-shaped welded, and the fixing bolts connect the shaft generator body fixing plate and the anti-sway body fixing plate; the shaft generator body screw acts on the shaft generator body threaded hole;

[0006] The anti-sway body comprises an anti-sway body upper section and an anti-sway body lower section, which are connected by an anti-sway body adjusting device; the anti-sway body adjusting device is a sleeve, which is arranged on the outer sides of the anti-sway body upper section and the anti-sway body lower section, and after adjusting the length and angle of the anti-sway body, the main body upper section, the anti-sway body lower section and the anti-sway body adjusting device are welded; the bottom end of the anti-sway body lower section is arranged on the hull through an anti-sway reinforcement bottom plate;

[0007] A first anti-sway body support and a second anti-sway body support are arranged below the anti-sway body adjustment device, and the first anti-sway body support and the second anti-sway body support are arranged on the hull through a supporting reinforcement bottom plate.

[0008] The angle between the anti-sway body and the vertical plane of the shaft-driven generator is 120°-150°.

[0009] At least two sets of anti-shake fixing devices are arranged on the shaft belt generator.

[0010] Compared with the prior art, the present invention has the following advantages: the device provides a solution that can effectively reduce the vibration and sway of the shaft generator body. When the marine shaft generator is running, the device can effectively reduce the vibration and shaking of the shaft generator body, avoid the occurrence of scratches between the internal stator of the shaft generator and the main shaft of the ship, and reduce the risk of equipment operation. At the same time, the size and direction of each component of the device can be fine-tuned according to actual conditions to reduce the difficulty of on-site construction, and by setting a suitable connection form, the impact of the sway-stopping parts on the installation of the ship's hull structure and other pipelines, channels and other components can be reduced. The device itself has the advantages of high rigidity, simple structure, low cost, convenient construction, and long service life. It can easily reduce the vibration and shaking of the shaft generator body and achieve a good sway-stopping effect. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0022] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0024] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
