AI Technical Summary
Existing shipboard concealed anchorages lack anti-collision structures, leading to dents and deformation of the top plate, affecting service life and safety.
An arc-shaped φ60mm round steel body is fixedly connected to the bottom surface of the top plate of the anchor hole, arranged around the anchor chain cylinder, and fixed to the top plate by welding. The welding width is 10mm and the angle is 40° to form an anti-collision structure.
It improves the structural strength and safety of the anchorage, prevents the top plate from sinking and deforming, extends service life and reduces maintenance costs.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of ship design technology, and specifically relates to an anchorage anti-collision structure. Background Technology
[0002] Generally, concealed anchorage structures on ships do not have collision protection structures. Figure 1 and Figure 2 This type of concealed anchorage design is susceptible to damage from the violent impact of the anchor, causing the top plate to dent and deform, thus affecting the lifespan of the anchorage and the safety of the ship. Summary of the Invention
[0003] To address the problems existing in the prior art, an anchor pit anti-collision structure is proposed, including a body, which is fixedly connected to the bottom surface of the top plate of the anchor pit, and the body is arranged to avoid the anchor chain cylinder on the top plate of the anchor pit.
[0004] Furthermore, the body is formed into an arc-shaped structure surrounding the anchor chain cylinder.
[0005] Furthermore, the main body is made of φ60mm round steel and is divided into two along a horizontal plane passing through the central axis.
[0006] Furthermore, the main body and the top plate are fixedly connected by welding.
[0007] Furthermore, the welding width between the body and the top plate is 10mm, and the welding angle between the body and the top plate is 40°.
[0008] The anchor cavity anti-collision structure provided by this invention has the following advantages over the prior art: This invention greatly improves the structural strength and safety of the anchorage, while also protecting the top plate of the anchorage from dents and deformation caused by external impacts, reducing maintenance costs and extending the service life of the anchorage.

Figure 3 (From BB's perspective) Figure 5 This is a schematic diagram of the welding between the anti-collision structure and the top plate in this application. Detailed Implementation
[0010] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0011] Reference Figures 3-4 This application proposes an anchorage anti-collision structure, which is made by dividing a φ60mm round steel bar in half along a horizontal plane passing through the central axis, and then welding it to the bottom surface of the top plate. This anti-collision structure is arranged around the outer edge of the anchor chain cylinder.
[0012] Reference Figure 5 The welding width between the body and the top plate is 10mm, and the welding angle between the body and the top plate is 40°.
[0013] Because a semi-circular steel bar is installed around the anchor chain tube on the top plate of the concealed anchorage, when the anchor is pulled upwards into the concealed anchorage, it only impacts the semi-circular steel bar on the top plate of the anchorage. The semi-circular steel bar bears the load, thus enhancing the strength of the anchorage and preventing the top plate from denting or deforming. This increases the safety and wear resistance of the anchorage, extending its service life. In summary, these are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. All equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the specification are within the scope of the present invention.
