Currently, general navigation marks do not have a buffer structure and have poor impact resistance. They are easily damaged by the impact under the beating of waves, and it is also easy to cause the hidden danger of damage due to excessive floating.

[0003] Therefore, it is necessary to provide a new impact-resistant navigation mark to solve the above technical problems. Content of the Utility Model

Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] The following describes the specific implementation of the present utility model in detail in conjunction with specific embodiments.

[0026] Please refer to Figures 1 to 5 , an impact-resistant beacon provided by an embodiment of the present utility model, the impact-resistant beacon includes: a floating disk seat 1, an elastic corrugated airbag ring 2, a descent component 3 and a protection component 4.

[0027] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 3 , it is assumed that an elastic corrugated airbag ring 2 is arranged in the floating disk seat 1, the elastic corrugated airbag ring 2 is installed in an annular groove 1a opened on the outer circumferential wall of the floating disk seat 1, and the inner circumferential wall of the elastic corrugated airbag ring 2 is fixedly connected to the groove wall of the annular groove 1a. A plurality of groups of annularly distributed descent components 3 are installed on the floating disk seat 1, and the descent component 3 includes a mounting cylinder 31. The mounting cylinder 31 is fixedly installed on a fixing frame 11 provided on the floating disk seat 1, and an elastically connected piston 32 is installed in the mounting cylinder 31. Specifically, a spring 36 is installed in the mounting cylinder 31. One end of the spring 36 is fixedly connected to the inner top wall of the mounting cylinder 31, and the other end of the spring 36 is fixedly connected to the upper surface of the piston 32. A piston rod 33 is fixedly installed at the bottom of the piston 32. The piston rod 33 extends out of the bottom of the mounting cylinder 31 and is fixedly installed with a conical rubber disk 34. An air port at the top of the mounting cylinder 31 is communicated with a communication hole 1b on the elastic corrugated airbag ring 2 through an air duct 35.

[0028] It should be noted that ropes and anchor hooks are installed at the bottom of the floating disk seat 1 to limit the floating range of the floating disk seat 1. Since a descent component 3 is provided on the side of the floating disk seat 1, when waves appear on the sea surface, the conical rubber disk 34 rises and falls with the undulating waves. At this time, the piston rod 33 on the conical rubber disk 34 slides along the installation cylinder 31. Thus, the piston 32 on the piston rod 33 can squeeze the gas in the installation cylinder 31 and compress the spring 36, and the gas in the installation cylinder 31 is discharged into the elastic corrugated airbag ring 2 through the air duct 35. Therefore, the elastic corrugated airbag ring 2 expands and increases the side area of the floating disk seat 1. On the one hand, the expanded elastic corrugated airbag ring 2 can effectively reduce the impact force of the sea waves on the buoy and reduce the amplitude of the entire buoy caused by the sea waves, effectively avoiding the phenomenon of the buoy tipping over. On the other hand, when the expanded elastic corrugated airbag ring 2 is impacted by the sea waves, the gas in the elastic corrugated airbag ring 2 flows back into the installation cylinder 31 and drives the piston 32 to slide down, so that the conical rubber disk 34 pushes the sea waves downward. At the same time, the gas in the elastic corrugated airbag ring 2 flowing back into the installation cylinder 31 drives the spring 36 to stretch, thereby effectively reducing the impact force received by the floating disk seat 1 and further improving the stability of the buoy.

[0029] In an embodiment of the present invention, please refer to Figure 4 and Figure 5 , a plurality of protection components 4 for protecting the floating disk seat 1 are arranged on the installation cylinder 31. The protection component 4 includes an installation ring 41. The installation ring 41 is sleeved on the installation cylinder 31 and is coaxially arranged with the installation cylinder 31. A plurality of coaxially arranged arc-shaped rubber sleeves 42 are fixedly sleeved on the installation ring 41. Each arc-shaped rubber sleeve 42 is rotatably connected to the installation ring 41. A plurality of radially arranged fixing rods 43 are fixedly installed on the installation ring 41. The connecting end of the fixing rod 43 is fixedly connected to the outer cylinder wall of the installation cylinder 31. The fixing rod 43 and the arc-shaped rubber sleeve 42 are arranged at intervals.

[0030] It should be noted that: when the installation cylinder 31 is impacted by seawater, since the arc-shaped rubber sleeve 42 is an elastic section, the impact force received by the installation cylinder 31 is reduced. At the same time, since the arc-shaped rubber sleeve 42 can rotate around the installation ring 41, the impact received by the installation cylinder 31 is further weakened;

[0031] Among them, a buoy post 5 is fixedly installed on the top of the floating disk seat 1, and a plurality of annular airbag rings 51 are fixedly embedded on the buoy post 5 at equal intervals up and down. The arranged annular airbag rings 51 greatly improve the impact resistance of the buoy post 5.

[0032] The working principle of the impact-resistant buoy provided by the present invention is as follows:

[0033] Install ropes and anchor hooks at the bottom of the floating disc seat 1 to limit the floating range of the floating disc seat 1. Since a descending component 3 is provided on the side of the floating disc seat 1, when waves appear on the sea surface, the conical rubber disc 34 rises and falls with the undulating waves. At this time, the piston rod 33 on the conical rubber disc 34 slides along the mounting cylinder 31, so that the piston 32 on the piston rod 33 can squeeze the gas in the mounting cylinder 31 and compress the spring 36. The gas in the mounting cylinder 31 is discharged into the elastic corrugated airbag ring 2 through the air duct 35. Therefore, the elastic corrugated airbag ring 2 expands and increases the side area of the floating disc seat 1. On the one hand, the expanded elastic corrugated airbag ring 2 can effectively reduce the impact force of the sea waves on the buoy and reduce the amplitude of the whole buoy caused by the sea waves, effectively avoiding the phenomenon of the buoy tipping over. On the other hand, when the expanded elastic corrugated airbag ring 2 is impacted by the sea waves, the gas in the elastic corrugated airbag ring 2 flows back into the mounting cylinder 31 and drives the piston 32 to slide down, so that the conical rubber disc 34 pushes the sea waves downward. At the same time, the gas flowing back into the mounting cylinder 31 in the elastic corrugated airbag ring 2 drives the spring 36 to stretch, further reducing the impact force on the floating disc seat 1 and further improving the stability of the buoy. When the mounting cylinder 31 is impacted by sea water, since the arc rubber sleeve 42 is an elastic section, the impact force on the mounting cylinder 31 is reduced. At the same time, since the arc rubber sleeve 42 can rotate around the mounting ring 41, the impact on the mounting cylinder 31 is further weakened.

[0034] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
