Description

TECHNICAL FIELD

[0001] The utility model relates to the field of side -pushing pipe flow guiding, especially a side -pushing pipe flow guiding structure. BACKGROUND

[0002] To meet the need of dynamic positioning, generally, side -pushing pipe is set up in the transverse of the ship body for installing side -pushing component, but the opening is formed in the transverse of the ship body on both sides of the side -pushing pipe, which causes the water flow to impact the back wall of the side -pushing pipe during navigation, and increases the navigation resistance of the ship body. SUMMARY

[0003] The utility model discloses a kind of side -pushing pipe flow guiding structures, which can solve the problem of increased navigation resistance of ship body caused by side -pushing pipe.

[0004] Therefore, the utility model adopts the following technical solutions:

[0005] A kind of side -pushing pipe flow guiding structure, the side of side -pushing pipe close to bow is fixed with flow guiding block, the surface of the flow guiding block is set as cambered surface, the cambered surface and bow surface link to form "C" shaped flow guiding surface, and the flow direction of water flow on the flow guiding surface deviates from the surface streamline of ship body.

[0006] Based on the above technical scheme, the utility model can also adopt the following further technical solutions, or use these further technical solutions in combination:

[0007] The junction of the side -pushing pipe and the ship body is pasted with a skin.

[0008] The outside of the flow guiding block is covered with CSM chopped felt.

[0009] The flow guiding block and the ship body / the side -pushing pipe are fixedly connected through structural adhesive.

[0010] The flow guiding block and the CSM chopped felt are fixedly connected through glass adhesive.

[0011] A 45-degree chamfer is provided between the side of the side -pushing pipe away from the bow and the ship body.

[0012] The flow guiding block is made of PVC foam.

[0013] Compared with the prior art, by setting flow guiding block, forming flow guiding surface, cutting and guiding the water flow outside the side -pushing pipe during navigation of the ship body, the flow direction is changed after the water flow flows through the flow guiding surface, avoiding impacting the back wall of the side -pushing pipe, thereby reducing the navigation resistance of the ship body.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote elements with the same or similar functions throughout. However, it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting this utility model. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this utility model.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] The present invention provides a side thrust pipe flow guiding structure, wherein a flow guiding block 2 is fixed on the side of the side thrust pipe 1 near the bow of the ship, and the surface of the flow guiding block 2 is set as an arc surface 21. The arc surface 21 is connected with the surface of the bow of the ship to form a “C” shaped flow guiding surface, and the water flow direction on the flow guiding surface deviates from the streamline of the ship surface.

[0022] like Figure 1 As shown, in a traditional side thruster 1 without a guide block 2, during ship navigation, the water flow follows the streamlines of the hull surface. Upon encountering the side thruster 1, due to the presence of the pipe opening, the water flow directly impacts the rear wall of the side thruster 1, resulting in increased navigation resistance; as... Figure 2 As shown, by setting the guide block 2, the water flow outside the side thrust pipe 1 can be cut and guided. After the water flows through the guide surface, the flow direction is changed, avoiding impact on the rear wall of the side thrust pipe, thereby reducing the hull's sailing resistance.

[0023] Skin 3 is pasted at the junction of the side thrust tube 1 and the hull.

[0024] The outer side of the flow guide block 2 is covered with CSM short cut felt 4 to avoid the flow guide block 2 from being impacted and falling off during sailing.

[0025] The flow guide block 2 and the ship body / side thrust pipe 1 are fixedly connected through structural glue, and 1152PA structural glue is adopted in the embodiment.

[0026] The flow guide block 2 and the CSM short cut felt 4 are fixedly connected through glass glue.

[0027] A 45-degree chamfer 5 is arranged between the side of the side thrust pipe 1 far away from the bow and the ship body.

[0028] The flow guide block 2 is made of PVC foam.
