Description

Technical Field

[0001] The utility model relates to the technical field of navigation aids, in particular to a spring type anti-collision top pole. Background Art

[0002] As a key infrastructure for guiding ships to sail safely, marine navigation aids play an indispensable role in global navigation activities. However, due to the harsh marine environment and frequent ship collisions, traditional navigation aids, especially the pole structure at the top, are often damaged. When the pole is knocked crooked, the lamp device on the navigation aid may also be damaged, thus affecting the normal use of the navigation aid. This not only increases the high maintenance cost, but also seriously affects the navigation function of the navigation aid, posing a threat to maritime traffic safety.

[0003] The design of traditional top poles is usually based on a fixed structure, that is, the top pole is connected to the navigation aid base, lacking effective anti-collision performance. Once encountering a ship collision, this rigid structure often cannot absorb or buffer the huge energy generated by the collision, resulting in the breakage of the top pole. To solve this problem, the industry has tried various solutions, such as using stronger materials, increasing the structure thickness, etc. However, these methods are not only costly, but the increase in weight further increases the burden on the base, reducing the stability and durability of the navigation aid.

[0004] Aiming at the above technical problems, this application aims to propose an innovative spring type anti-collision top pole structure to fill the gap in the existing technology and provide a solution that can significantly improve the anti-collision performance of navigation aids, reduce maintenance costs and ensure maritime traffic safety. Content of the Utility Model

[0005] The utility model proposes a spring type anti-collision top pole, which solves the above problems existing in the prior art during use.

[0006] The technical solution of the utility model is realized as follows: A spring type anti-collision top pole includes a top pole body and a spring device. The top pole body includes an upper pole component and a lower pole component. The spring device is arranged between the upper pole component and the lower pole component. The spring device includes at least one elastic element, and the elastic element can bend and stretch within a preset elastic range.

[0007] Preferably, the elastic element is a helical spring, and the size and thickness of the helical spring are adapted to the upper pole component and the lower pole component.

[0008] Preferably, the upper pole component and the helical spring are fixed by welding, and the lower pole component and the helical spring are fixed in the same way.

[0009] Preferably, both the upper benchmark component and the lower benchmark component include connection kits. The upper and lower ends of the helical spring are respectively welded to the connection kits of the upper benchmark component and the lower benchmark component. The inner side wall of the connection kit is provided with internal threads. The upper benchmark component further includes an upper benchmark, and the lower benchmark component further includes a lower benchmark. The lower end of the upper benchmark is threadedly connected to the connection kit of the upper benchmark component, and the upper end of the lower benchmark is threadedly connected to the connection kit of the lower benchmark component.

[0010] Preferably, the connection kit includes a limiting step for the end of the helical spring to abut against and be welded on, and an extended positioning cylinder integrally formed on the connection kit and extending into the helical spring.

[0011] Preferably, a screw is threadedly connected to the side wall of the extended positioning cylinder. The head of the screw is located outside the helical spring, and a washer is pressed between the head of the screw and the helical spring.

[0012] Preferably, the material of the helical spring is stainless steel, alloy steel or composite material.

[0013] In summary, the beneficial effects of the present utility model are as follows:

[0014] 1. By introducing a spring device into the top benchmark structure, the present utility model can generate elastic deformation when being impacted by a ship, effectively absorb and disperse the impact energy, thereby avoiding the rigid damage of the top benchmark and improving the service life of the navigation mark.

[0015] 2. The spring device can effectively disperse and absorb the impact force generated by the collision, greatly reducing the risk of damage to the top benchmark.

[0016] 3. The spring device can quickly return to its original state after the collision, maintaining the normal function of the top benchmark.

[0017] 3. In addition, after the collision occurs, even if the upper half of the top benchmark, that is, the upper benchmark component, comes into contact with the lamp device, since it is connected to the lower benchmark component through a helical spring and is movable relative to the lamp device, the extrusion of the top benchmark on the lamp device can be reduced, thereby reducing the damage to the lamp device.

[0025] Embodiment:

[0026] As Figures 1 to 4 shown, the present utility model discloses a spring-type anti-collision top pole, which includes a top pole body and a spring device. Among them, the top pole body includes an upper pole component 1 and a lower pole component 2, and the spring device is arranged between the upper pole component 1 and the lower pole component 2. The lower pole component 2 is fixed on the navigation buoy. A top mark 7 is fixedly connected to the upper end of the upper pole component 1. In addition, a lantern 8 is provided on one side of the top pole body of the navigation buoy. The spring device can generate elastic deformation when subjected to external impact, absorb and disperse the impact energy, thereby protecting the structure of the top pole body from damage. And the spring device can quickly return to its original state after the collision and maintain the normal function of the top pole. In addition, after the collision occurs, even if the upper half of the top pole, that is, the upper pole component 1, comes into contact with the lantern 8, since it is connected to the lower pole component 2 through the spring device and is movable relative to the lantern 8, the extrusion of the top pole on the lantern 8 can be reduced, thereby reducing the damage to the lantern 8. Among them, the spring device includes at least one elastic element, and the elastic element can bend and stretch within a preset elastic range to adapt to collisions of different intensities.

[0027] Specifically, the elastic element is a coil spring 3, the size and thickness of the coil spring 3 are compatible with the upper benchmark assembly 1 and the lower benchmark assembly 2. The length of the coil spring 3 is preferably about 25 cm, and the length of the lower benchmark assembly 2 is preferably about 15 cm. The lower end of the lower benchmark assembly 2 should be able to be assembled normally with the existing navigation mark base 9, and the upper end of the upper benchmark assembly 1 should be able to be installed normally with the existing top mark 7.

[0028] The upper pole assembly 1 and the coil spring 3 are fixed by welding, and the lower pole assembly 2 and the coil spring 3 are also fixed by welding. The fixing by welding is firm and reliable.

[0029] In the present invention, the upper rod assembly 1 and the lower rod assembly 2 both include a connection kit 4, wherein the upper and lower ends of the coil spring 3 are respectively welded to the connection kits 4 of the upper rod assembly 1 and the lower rod assembly 2, and the inner side wall of the connection kit 4 is provided with an internal thread 41, and the upper rod assembly 1 also includes an upper rod 11, and the lower rod assembly 2 also includes a lower rod 21, wherein the lower end of the upper rod 11 is threadedly connected to the connection kit 4 of the upper rod assembly 1, and the upper end of the lower rod 21 is threadedly connected to the connection kit 4 of the upper rod assembly 1. It is connected to the connecting kit 4 of the lower benchmark assembly 2. In this way, when the coil spring 3 undergoes irreversible deformation, or the welding structure between the coil spring 3 and the upper benchmark assembly 1 and the lower benchmark assembly 2 is damaged, there is no need to replace the entire upper benchmark assembly 1, the lower benchmark assembly 2 and the coil spring 3. Only the connecting kit 4 at the upper and lower ends of the coil spring 3 and the upper benchmark assembly 1 and the lower benchmark assembly 2 need to be replaced, and the upper benchmark rod 11 and the lower benchmark rod 21 can also be disassembled and continued to be used, which reduces costs and improves the convenience of maintenance.

[0030] Furthermore, the connecting kit 4 includes a limiting step 42 for the end of the coil spring 3 to abut and be welded thereon, and an extending positioning cylinder 43 extending into the coil spring 3 is integrally formed on the connecting kit 4. This structure can enhance the structural strength of the coil spring 3 fixed on the connecting kit 4.

[0031] In addition, a screw 5 is threadedly connected to the side wall of the extended positioning cylinder 43, and the head of the screw 5 is located outside the coil spring 3. A washer 6 is pressed between the head of the screw 5 and the coil spring 3. The washer 6 is pressed on the coil spring 3 to further improve the connection strength between the coil spring 3 and the connecting kit 4.

[0032] It should also be noted that the material of the coil spring 3 is stainless steel, alloy steel or composite material to ensure that it has excellent corrosion resistance and long service life in the marine environment.

[0033] It should be noted that the terms used in the present utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0034] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
