Description

Technical Field

[0001] The utility model relates to the field of marine navigation marks, in particular to a marine floating mobile navigation mark. Background Art

[0002] A navigation mark is a facility or system that provides safety information for various water activities. It is installed in or near navigable waters to mark the location of waterways, anchorages, shoals and other obstacles, indicate water depth and wind conditions, and direct traffic in narrow waterways. Navigation marks play an important role in supporting water transportation, fisheries, marine development, and national defense construction. However, when passing ships such as fishing boats are sailing, they often scratch the navigation marks, causing wear and even damage to the navigation marks, reducing the life of the navigation marks. Utility Model Content

[0003] The purpose of this application is to provide a floating mobile navigation mark at sea, aiming to solve the problems existing in the prior art.

[0004] The embodiment of the present application provides a floating mobile navigation mark at sea, including a floating body, the floating body is cylindrical, an upper floating body is installed above the floating body, and a lower floating body is installed below the floating body; the outer periphery of the floating body is rotatably connected with an anti-scratch ring;

[0005] The anti-scratch ring includes a base fixedly connected to a floating body, a swivel is arranged on the outside of the base, arc grooves are opened on the upper and lower end surfaces of the base, balls are arranged in the arc grooves, and arc grooves are arranged on the swivel corresponding to the balls, so that the balls are embedded between the base and the swivel, and the swivel rotates relative to the base through the balls; a plurality of block-shaped elastic bodies are arranged at intervals on the outer circumferential surface of the swivel.

[0006] Furthermore, the floating body, the upper floating body and the lower floating body are all made of polyethylene plastic, and the interior of the floating body is filled with EPS foam.

[0007] Furthermore, a baffle bar extending in the upward and downward directions is arranged on the outer side of the base body, and a limiting groove is provided on the swivel body corresponding to the baffle bar. The baffle bar is located in the limiting groove and there is a gap between the baffle bar and the limiting groove.

[0008] Furthermore, there is a gap between the outer end surface of the base body and the inner end surface of the swivel body.

[0009] Furthermore, a reflective strip is provided on the upper end surface of the swivel, and the reflective strip is annular and concentric with the anti-scratch ring.

[0010] Furthermore, the material of the elastic body is rubber.

[0011] The beneficial effect of the utility model is that a rotatably connected anti-scratch ring is arranged on the outer periphery of the navigation mark floating body. When a ship approaches and scratches the navigation mark, it will directly contact the anti-scratch ring to avoid contact with the floating body. After the ship contacts the anti-scratch ring, as the ship continues to move, sliding friction is generated with the swivel, which can drive the swivel to rotate. Rolling friction is formed between the swivel and the base on the floating body through the ball bearings, so that the base on the floating body is subjected to rolling friction. The surface loss caused by rolling friction is significantly lower than that caused by sliding friction, thereby protecting the floating body, preventing the floating body from being damaged, and extending the life of the floating body.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 As shown, a floating mobile navigation mark at sea includes a floating body 1, which is cylindrical, an upper floating body 2 is installed above the floating body 1, and a lower floating body 3 is installed below the floating body 1. In this embodiment, the upper floating body 2 and the lower floating body 3 are in the shape of a cone or a truncated cone, and the lower floating body 3 has a weight to help the buoy to remain stable in the sea. The shape of the upper floating body 2 also helps the buoy to remain stable in the sea. The floating body 1, the upper floating body 2 and the lower floating body 3 are all made of polyethylene plastic, and the floating body 1 is filled with EPS foam.

[0019] The outer periphery of the floating body 1 is rotatably connected with an anti-scratch ring 4 so that the anti-scratch ring 4 is located above the sea surface. The anti-scratch ring 4 can rotate relative to the floating body 1 to reduce friction damage when a ship collides or rubs against the surface of the navigation mark.

[0020] Specifically, if Figure 2 and Figure 3 As shown, the anti-scratch ring 4 includes a base 5 fixedly connected to the floating body 1, the base 5 is annularly sleeved on the floating body 1, a swivel 6 is arranged on the outside of the base 5, and there is a gap between the outer end surface of the base 5 and the inner end surface of the swivel 6 to prevent the swivel 6 from contacting with the base 5 and generating sliding friction. The upper and lower end surfaces of the base 5 are provided with arc grooves, and balls 7 are arranged in the arc grooves. The swivel 6 corresponding to the balls 7 is provided with arc grooves in a corresponding position, so that the balls 7 are embedded between the base 5 and the swivel 6, and the swivel 6 rotates relative to the base 5 through the balls 7. There are multiple balls 7, and optionally, a retaining frame can be installed between the multiple balls 7 to maintain the positions of the multiple balls 7. A sliding seal 8 is arranged between the swivel 6 and the floating body 1 to isolate the balls 7 from contact with seawater.

[0021] like Figure 3 As shown, a baffle 9 extending in the upward and downward direction is arranged on the outer side of the base 5, and a limiting groove 10 is provided on the swivel 6 corresponding to the baffle 9. The baffle 9 is located in the limiting groove 10 and there is a gap between the baffle 9 and the limiting groove 10. The swivel 6 and the base 5 are in contact with each other through the ball 7. The baffle 9 does not contact the swivel 6 during normal use. The baffle 9 is used to prevent the swivel 6 from being misaligned with the base 5 and the swivel 6 from being separated from the base 5, and plays a limiting role.

[0022] A plurality of block-shaped elastomers 11 are arranged at intervals on the outer circumferential surface of the swivel 6. The material of the elastomer 11 is preferably rubber, which has elasticity and friction. When friction occurs with a ship, the friction between the elastomer 11 and the ship is relatively large, so that the swivel 6 can be driven to rotate when the ship passes by, thereby reducing scratches on the floating body 1 and playing a role in protecting the floating body 1.

[0023] like Figure 1 The upper end surface of the swivel 6 is provided with a reflective strip 12, which is annular and concentric with the anti-scratch ring 4. When a ship passes by at night, the light shines on the reflective strip 12 to reflect light to remind the ship to avoid it.

[0024] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
