Description

Technical Field

[0001] This utility model belongs to the field of ship structure technology, and in particular, it is a high-strength and easy-to-assemble protective keel. Background Technology

[0002] Yachts, as a form of water transportation, have seen increasingly widespread use in recent years, playing a crucial role in transporting personnel and supplies, especially in flood control and disaster relief. However, due to limitations imposed by non-human factors such as severe weather and water surface conditions, as well as human factors like operator skill, collisions between ships during navigation are inevitably on the rise. If the hull lacks adequate collision and wave-resistant preventative measures, it can suffer significant damage. Most existing hulls incorporate cushioning materials, such as tires, on the side plating to protect it. However, this method offers limited protection for the hull side, making it susceptible to damage during collisions and thus affecting normal use.

[0003] In the utility model patent with publication number CN220996650U, although the hull is protected by the keel at the mouth, the light strip groove is located between the fixing slot and the connecting part. When the hull is sailing at night, it can only illuminate the inside of the hull, and has little effect on illuminating the outside of the hull. This makes it difficult to observe the surrounding environment at night, which can easily lead to contact with foreign objects in the water and damage to the hull. Summary of the Invention

[0004] In view of this, the present invention provides a high-strength and easy-to-assemble protective keel to solve the above problems.

[0005] A high-strength and easily assembled protective keel includes an opening keel. The opening keel includes a keel body, a collision avoidance groove on one outer side wall of the keel body, a connecting portion on the adjacent outer side wall of the collision avoidance groove, an external light strip groove between the collision avoidance groove and the connecting portion for illuminating the external space of the hull, and two reinforcing ribs on the inner side wall of the keel body facing away from the connecting portion for improving the bending and torsional shear resistance of the keel body. The connecting portion includes a fixing groove for connecting and fixing a side plate to secure the keel body to the hull. In a cross-section perpendicular to the extension direction of the keel body, the reverse extension line of the fixing groove intersects with another side wall opposite the side wall where the connecting portion is located, forming an intersection point. The two reinforcing ribs are located at the midpoint of the perpendicular line from this intersection point to the side wall where the fixing groove is located. The two reinforcing ribs balance the torsional shear force during ship movement, thereby improving the torsional shear resistance of the keel body.

[0006] Furthermore, the mouth keel also includes a fixing slot disposed on the outer side wall of the keel body facing away from the anti-collision slot, an inner light strip slot disposed between the fixing slot and the connecting part, and an inclined surface disposed on the outer side wall between the outer side wall of the keel body facing away from the connecting part and the side wall where the anti-collision slot is located.

[0007] Furthermore, the main body of the keel is a hollow tubular structure.

[0008] Furthermore, the fixing slot is a T-shaped slot used for installing marine fittings.

[0009] Furthermore, the anti-collision slot includes a groove and a plurality of limiting protrusions disposed within the groove.

[0010] Furthermore, the connecting part also includes a short baffle disposed on the keel body, and a long baffle disposed at a distance from the short baffle and close to the anti-collision slot side, the short baffle and the long baffle facing the fixed slot side, and the extending directions of the short baffle and the long baffle being parallel.

[0011] Furthermore, the inner light strip groove includes two first support portions disposed at the opening of the inner light strip groove.

[0012] Furthermore, the outer light strip groove includes two second support portions disposed at the groove opening of the outer light strip groove.

[0013] Furthermore, the inclined surface is used to guide water flow from the surface of the keel body.

[0014] Compared with existing technologies, the high-strength and easily assembled protective keel provided by this utility model achieves rapid assembly of ship components through the connection and cooperation of T-bolts with the fixing slots. Furthermore, by setting the external light strip groove on the keel body, the installation of light strips can improve the visibility of the hull during nighttime navigation, preventing collisions and illuminating the external space of the hull to prevent the hull from contacting foreign objects and causing damage during nighttime navigation. Simultaneously, by setting two reinforcing ribs on the side of the keel body opposite to the connecting part, the bending and torsional shear resistance of the keel body is improved to prevent deformation under external pressure and torsional deformation caused by swaying during voyage.

[0015] Figure 1 This is a schematic diagram of a high-strength and easy-to-assemble protective keel provided by this utility model.

[0016] Figure 2 for Figure 1A plan view of a high-strength and easy-to-assemble protective keel. Detailed Implementation

[0017] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0018] like Figure 1 and Figure 2 The diagram shows a structural schematic of a high-strength and easily assembled protective keel provided by this utility model. The high-strength and easily assembled protective keel includes an opening keel 10. The opening keel 10 includes a keel body 11, a fixing groove 12 disposed on one outer side wall of the keel body 11, an anti-collision groove 13 disposed on the outer side wall of the keel body 11 facing away from the fixing groove 12, a connecting part 14 for assembling the keel body 11 onto a ship, an inner LED strip groove 15 disposed between the fixing groove 12 and the connecting part 14, and an outer LED strip groove 16 disposed between the anti-collision groove 13 and the connecting part 14. The high-strength and easily assembled protective keel also includes other functional modules, such as an anti-oxidation coating and a decorative layer applied to the keel body 11 to prevent rust, which are technologies known to those skilled in the art and will not be described in detail here.

[0019] The keel body 11 is a hollow tubular structure that can extend indefinitely. The keel body 11 can be formed by extrusion of metal materials such as aluminum alloy or steel, and the wall thickness of the keel body 11 can be increased or decreased according to actual needs.

[0020] The fixing slot 12 is located on the outer side of the keel body 11 along its length and is a T-shaped slot. The fixing slot 12 is used to install marine accessories, such as brackets and bases. Specifically, a T-bolt can be inserted into the fixing slot 12 and then rotated to engage and fix the T-bolt onto the fixing slot 12. Marine accessories such as brackets and bases can be fixed to the T-bolt, and the nut can be tightened to secure them in the fixing slot 12. In use, the nut can be removed to replace different types of accessories as needed. The T-bolt and the fixing slot 12 facilitate quick assembly and replacement of marine accessories.

[0021] The anti-collision slot 13 and the fixing slot 12 are respectively disposed on opposite sides of the keel body 11. The anti-collision slot 13 includes a groove 131 and a plurality of limiting protrusions 132 disposed in the groove 131.

[0022] The groove 131 is used to embed and install anti-collision strips (not shown in the figure), so the anti-collision groove 13 is generally located on the outside of the ship when in use.

[0023] The limiting protrusion 132 is used to fix the anti-collision strip to the groove 131, thereby increasing the stability of the anti-collision strip after installation with the groove 131 and preventing the anti-collision strip from easily falling off after a collision. The length of the limiting protrusion 132 is the same as the length of the groove 131 along the length direction of the keel body 11, and extends into the interior of the groove 131. The number of limiting protrusions 132 can be set according to actual needs. In this embodiment, there are four limiting protrusions 132, which are evenly arranged on both sides of the groove 131.

[0024] like Figure 2 As shown, the connecting portion 14 is disposed on an outer side wall between the side wall where the anti-collision slot 13 and the fixing slot 12 are located. The connecting portion 14 includes a short baffle 141 disposed on the keel body 11, and a long baffle 142 disposed at a distance from the short baffle 141 and close to the side of the anti-collision slot 13. Both the short baffle 141 and the long baffle 142 are inclined toward the fixing slot 12, and the extending directions of the short baffle 141 and the long baffle 142 are parallel.

[0025] The connecting portion 14 further includes a fixing groove 143 located between the short baffle 141 and the long short plate 142. The fixing groove 143 is used to insert a ship side plate (not shown) to fix the keel body 11 to the hull. Specifically, the ship side plate (not shown) is inserted between the short baffle 141 and the long short plate 142. At this time, both ends of the ship side plate (not shown) are respectively abutted and fixed by the short baffle 141 and the long short plate 142. Then, the ship side plate (not shown) is welded and fixed in the connecting portion 14 by welding process to fix the keel 10 to the hull.

[0026] The inner light strip groove 15 is used to install a light strip. The inner light strip groove 15 also includes two first support portions 151 disposed near the groove opening to prevent the light strip from falling out of the inner light strip groove 15 after installation. Specifically, both ends of the light strip are supported by the two first support portions 151 to prevent it from falling. After the light strip is installed, the inner light strip groove 15 can serve both lighting and decorative purposes, illuminating the interior space of the ship and improving its aesthetics.

[0027] The outer light strip groove 16 has the same structure and function as the inner light strip groove 15. Only the components of the outer light strip groove 16 will be described here. The outer light strip groove 16 also includes two second support portions 161 disposed near the opening of the outer light strip groove 16. After the light strip is installed in the outer light strip groove 16, it can illuminate the external space of the hull to improve its visibility when the hull is traveling at night, avoiding collisions, and also illuminate the external space to prevent the hull from hitting foreign objects and causing damage to the hull.

[0028] like Figure 2 As shown, the keel body 11 is also provided with two reinforcing ribs 17 to improve its strength. The two reinforcing ribs 17 are formed on the inner sidewall of the keel body 11 facing away from the connecting portion 14. The reinforcing ribs 17 can be rectangular strips, extruded and extending together with the keel body 11. When the keel body 11 is subjected to a force perpendicular to the direction of the fixing slots 12 and the anti-collision slots 13, the reinforcing ribs 17 can support the keel body 11, thereby improving its compressive strength and bending resistance, and preventing damage from external pressure.

[0029] The reinforcing rib 17 also improves the torsional shear resistance of the keel body 11. Specifically, when the connecting part 14 is fixed to the side plate of the ship's hull, the hull will sway from side to side during the ship's movement, causing the keel body 11 to sway. At this time, the keel body 11 will be subjected to a force exerted by the side plate of the hull on the connecting part 14, and this force is perpendicular to the arrangement direction of the short plate 141 and the long plate 142. This force will cause the keel body 11 to have a tendency to rotate and twist. At this time, the keel body 11 on the side away from the connecting part 14 is prone to deformation under the action of this force, which may damage the keel body 11. On the cross section perpendicular to the extension direction of the keel body 11, the reverse extension line of the extension direction of the fixing groove 143 intersects with another side wall opposite to the side wall where the connecting part 14 is located and forms an intersection point. The two reinforcing ribs 17 are located at the midpoint of the perpendicular line from this intersection point to the side wall where the fixing groove 12 is located. The two reinforcing ribs 17 are used to balance the torsional shear force during the ship's movement, thereby improving the torsional shear resistance of the keel body 11.

[0030] An inclined surface 18 is also provided between the outer wall of the keel body 11 facing away from the connecting part 14 and the anti-collision groove 13. The inclined surface 18 is used to guide water splashed onto the surface of the keel body 11 to the water surface and change the position of the edges of the keel body 11, making its surface smoother and without sharp protrusions, making it more comfortable for the operator to hold and improving the operator's user experience.

[0031] Compared with the prior art, the high-strength and easy-to-assemble protective keel provided by this utility model achieves rapid assembly of ship accessories through the connection and cooperation of T-bolts with the fixing slot 12. Furthermore, by providing the external light strip slot 16 on the keel body 11, the installation of light strips can improve the visibility of the hull during nighttime navigation, preventing collisions and illuminating the external space of the hull to prevent the hull from contacting foreign objects and causing damage during nighttime navigation. Simultaneously, by providing two reinforcing ribs 17 on the side of the keel body 11 opposite to the connecting part 14, the bending resistance and torsional shear resistance of the keel body 11 are improved, preventing deformation of the keel body 11 under external pressure and torsional deformation caused by swaying during voyage.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
