[0018] The following further details the specific embodiments of the present utility model. It should be understood that the description of the embodiments of the present utility model herein does not limit the protection scope of the present utility model.

[0019] As Figures 1 to 3As shown, it is a schematic structural diagram of the keel structure provided by the present utility model and arranged on the ship's side. The keel structure arranged on the ship's side includes a keel main body 10 and a mounting groove group 20 arranged on the keel main body 10. The keel structure arranged on the ship's side also includes some other functional modules, such as a waterproof coating provided on the surface of the keel main body 10, etc., which should be well-known technologies to those skilled in the art and will not be elaborated in detail here one by one.

[0020] The keel main body 10 is a hollow tube body, which increases the structural strength of the keel main body 10 through the tubular structure while reducing the weight, so as to reinforce the edge of the hull. The top of the cross-section of the keel main body 10 is an arc with a higher middle and lower sides on both sides, so that the top of the keel main body 10 is arc-shaped, and further, when forces are applied on both sides of the keel main body 10, better support is provided through the arc structure. The keel main body 10 is in a U shape and fits the contour of the ship. It should be noted that the keel main body 10 mainly covers the bow and both sides of the ship and does not cover the tail of the ship. The keel main body 10 is in a U shape, so it has the same shape as the outer contour of the hull. In this embodiment, the bow of the hull is an acute angle, so the bent part of the U shape of the keel main body 10 is also an acute angle. The material of the keel main body 10 can be plastic or aluminum alloy, which provides stable support while reducing the weight.

[0021] Since the keel main body 10 is a tube body, it is possible to bend the keel main body 10 according to the contours of the bow and both sides of the hull, so that the bent keel main body 10 fits the contour of the hull, and further, the keel main body 10 fits the hull contour.

[0022] The mounting groove group 20 includes an inner mounting groove 21 arranged on one side wall of the keel main body 10, an outer mounting groove 22 arranged on the other side wall of the keel main body 10, a bottom mounting groove 23 arranged at the bottom of the keel main body 10, and a bottom connection groove 24 arranged at the bottom of the keel main body 10. The inner mounting groove 21 and the outer mounting groove 22 are respectively arranged on two opposite side walls.

[0023] The inner installation groove 21 is located inside the U-shape of the keel body 10 and is used to fix marine accessories such as brackets, bases, and boat covers. During use, one end of the marine accessory is snapped into the inner installation groove 21 and fixed to the bottom of the groove by bolts, or a pressing strip is pressed into the inner installation groove 21 to fix the sheet-shaped accessory in the inner installation groove 21. The inner installation groove 21 is a rectangular groove, and two first retaining pieces 211 are symmetrically arranged at the notch of the inner installation groove 21. One side of the first retaining piece 211 is flush with the notch of the inner installation groove 21, and the ends of the two first retaining pieces 211 are spaced apart. During use, the first retaining piece 211 can block external dust and debris from entering and can also limit the accessories in the inner installation groove 21 from coming out.

[0024] The outer installation groove 22 is located outside the U-shape of the keel body 10 and is used to clamp a rubber protection strip to protect the side plate or the bow of the hull from external impacts. When the rubber protection strip is placed in the outer installation groove 22, a part of the rubber protection strip will protrude from the notch of the outer installation groove 22, so as to isolate the external object from the hull during impact. The cross-section of the outer installation groove 22 is a rounded rectangle. Two second retaining pieces 221 are symmetrically arranged at the notch of the outer installation groove 22, and at least one pair of protrusions 222 are symmetrically arranged on the inner walls of the second retaining pieces 221 respectively. The second retaining piece 221 is used to limit the position of the rubber protection strip, and the protrusion 222 is used to increase the friction between the outer installation groove 22 and the rubber protection strip. In this embodiment, the number of the protrusions 222 is two pairs, so as to ensure stable friction. The inner walls of the two retaining pieces 221 are inclined, so that the cross-section of the outer installation groove 22 is approximately triangular. The inclined inner walls of the retaining piece 221 can better clamp the rubber protection strip located between them.

[0025] The bottom installation groove 23 is arranged at the bottom of the keel body 10 and is used to install a light strip assembly or cooperate to fix some marine accessories such as brackets, bases, and boat covers, etc. The bottom installation groove 23 is a U-shaped groove. Two third retaining pieces 231 are symmetrically arranged at the notch of the bottom installation groove 23 and are used to prevent the objects in the groove from coming out. The bottom installation groove 23 is closer to the outer installation groove 22 than the bottom connection groove 24. After the bottom connection groove 24 is fixedly connected to the hull, the bottom installation groove 23 is located outside the hull, which is convenient for the light strip to illuminate the outside of the hull.

[0026] The bottom connection groove 24 is located at the bottom of the keel main body 10 and is used to fix the keel main body 10 on the hull. The inclined settings are provided on both side walls of the bottom connection groove 24, and the end of the bottom connection groove 24 faces the inner wall of the U shape, so as to fit the inclined angle of the ship side plate. The length of the side wall plate of the installation groove 24 near the inner installation groove 21 is less than the length of the side wall on the other side of the installation groove 24, that is, during use, one side of the end is located inside the hull while the long side is located outside the hull. The side wall located outside the hull can provide a good supporting effect, avoiding too many accessories being set on the outside of the keel main body 10 and turning outward, resulting in the detachment of the keel main body 10.

[0027] During installation, the keel main body 10 with the corresponding profile is processed according to the profile of the bow and both sides of the hull. Then, the side plate of the ship is snapped into the bottom installation groove 23 of the keel main body 10 from bottom to top, and the keel main body 10 is fixed to the hull by welding. During use, the corresponding accessories are snapped into the inner installation groove 22 and the bottom installation groove 23 through bolts or mounting buckles, and the effects of quick disassembly and stable installation can be achieved. Snapping the rubber protection strip into the outer installation groove 22 is not only convenient for quick installation and positioning, but also convenient for subsequent replacement of a new rubber protection strip.

[0028] Compared with the prior art, the keel structure provided by the present utility model and arranged on the ship's side increases the structural strength of the top of the side plate and the top of the bow of the hull, and extends the service life of the hull. By providing an installation groove group 20 on the keel main body 10, installation positions are provided for various accessories that need to be installed during the use of the hull, facilitating the disassembly, assembly and positioning of the accessories. Specifically, the installation groove group 20 includes an inner installation groove 21 arranged on one side of the keel main body 10, an outer installation groove 22 arranged on the outside of the keel main body 10, and a bottom installation groove 24 arranged at the bottom of the keel main body 10. The inner installation groove 21 is used for quickly installing brackets, bases and ship covers. The outer installation groove 22 is used for installing rubber protection strips to reduce the impact of external objects on the hull, while the bottom installation groove 24 can install a light strip to provide illumination for the water surface and the ship side, and can also cooperate with the inner installation groove 21 to fix brackets, bases and ship covers.

[0029] The above is only a preferred embodiment of the present utility model and is not used to limit the protection scope of the present utility model. Any modification, equivalent replacement or improvement within the spirit of the present utility model is covered within the scope of the claims of the present utility model.
