It is an indispensable safety device for ship navigation. Existing lightning rods are all welded to the ship's mast and are not detachable. When a lightning rod is damaged, it must be removed by professional workers through mechanical means, such as flame cutting, which is very troublesome. Moreover, working at heights poses a great safety risk to construction workers and can easily cause crew members to fall into the water. Therefore, this utility model provides a marine lightning rod device that is easy to disassemble. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a marine lightning rod device that is easy to disassemble, thus solving the problems mentioned in the background section.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a marine lightning rod device that is easy to disassemble, including a ship mast top plate, and a lightning rod mounting base installed on the ship mast top plate. The top of the lightning rod mounting base is provided with a lightning rod mounting hole, and a lightning rod is inserted into the lightning rod mounting hole. The lightning rod mounting base and the lightning rod are fixed together by a locking component. The locking assembly includes multiple upper locking screw holes circumferentially opened on the outer side of the upper end of the lightning rod mounting base, and upper locking bolts screwed into the internal threads of the upper locking screw holes. The lower end of the lightning rod mounting base has four rectangular grooves. The inner sidewall of each groove has multiple lower locking screw holes around the lower end of the lightning rod mounting base. Each lower locking screw hole has a lower locking bolt screwed into it.
[0005] As a further technical solution of this utility model, the upper locking bolt and the upper locking screw hole are threadedly connected, and one end of the upper locking bolt is screwed into the upper locking screw hole and extends into the lightning rod mounting hole and abuts against the surface of the lightning rod.
[0006] As a further technical solution of this utility model, the lower locking bolt is threadedly connected to the lower locking screw hole, and one end of the lower locking bolt is screwed into the lower locking screw hole and extends into the lightning rod mounting hole and abuts against the surface of the lightning rod.
[0007] As a further technical solution of this utility model, each of the grooves has a corresponding mounting seat screw hole at the bottom inner side and the top of the ship mast. A fixing bolt is screwed into the mounting seat screw hole, and the lightning rod mounting seat is fixedly connected to the ship mast top plate by the fixing bolt.
[0008] As a further technical solution of this utility model, the ship mast top plate and the lightning rod mounting base are both made of metal, and the surfaces of the ship mast top plate and the lightning rod mounting base are coated with anti-corrosion paint.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0014] Please see Figure 1-3 This utility model provides a technical solution for a marine lightning rod device that is easy to disassemble: A marine lightning rod device that is easy to disassemble includes a mast top plate 1, which is the top load-bearing structure of the mast. A lightning rod mounting base 2 is installed on the mast top plate 1. Both the mast top plate 1 and the lightning rod mounting base 2 are made of metal, such as 304 stainless steel, which has excellent corrosion resistance and can adapt to the high salt spray environment at sea. The surfaces of the mast top plate 1 and the lightning rod mounting base 2 are coated with anti-corrosion paint, preferably marine-specific epoxy anti-corrosion paint, to further enhance corrosion resistance and extend the service life of the device. The top of the lightning rod mounting base 2 has a lightning rod mounting hole 21, into which a lightning rod 5 is inserted. The lower end of the lightning rod 5 is adapted to the lightning rod mounting hole 21 and can be directly inserted into the hole, providing initial positioning for the lightning rod 5.
[0015] The lightning rod mounting base 2 and the lightning rod 5 are fixed together by a locking assembly. The locking assembly includes multiple upper locking screw holes 221 circumferentially opened on the upper outer side of the lightning rod mounting base 2 and upper locking bolts 22 screwed into the upper locking screw holes 221. The upper locking bolts 22 and the upper locking screw holes 221 are threaded together. The upper locking bolts 22 are made of stainless steel. After being screwed in, their ends extend into the lightning rod mounting holes 21 and tightly abut against the outer surface of the lightning rod 5, restricting the radial movement of the lightning rod 5 from the top. The lower end of the lightning rod mounting base 2 has four rectangular grooves 3. The inner sidewall of each groove 3 has multiple lower locking screw holes 231 around the lower end of the lightning rod mounting base 2. Each lower locking screw hole 231 is threaded with a lower locking bolt 23. The lower locking bolt 23 is threaded to the lower locking screw hole 231. The lower locking bolt 23 is also made of stainless steel. Its end extends into the lightning rod mounting hole 21 and abuts against the surface of the lightning rod 5. It cooperates with the upper locking bolt 22 to form a double fixation of the lightning rod 5 from both the upper and lower positions, effectively preventing it from loosening or falling off in severe sea conditions.
[0016] Each groove 3 has a corresponding mounting screw hole 41 at its inner bottom and at the top of the mast plate 1. A fixing bolt 4 is screwed into the mounting screw hole 41. The lightning rod mounting seat 2 and the mast plate 1 are fixedly connected by the fixing bolt 4. The fixing bolt 4 is made of stainless steel to ensure connection strength and corrosion resistance.
[0017] The working principle of this utility model is as follows: the lightning rod mounting base 2 is placed in the preset installation position of the top plate 1 of the ship mast, so that the mounting base screw hole 41 at the bottom of the inner side of the groove 3 is aligned with the mounting base screw hole 41 on the top plate 1 of the ship mast; the spring washer is put on the fixing bolt 4, and then the fixing bolt 4 is screwed into the aligned mounting base screw hole 41, and tightened with a torque wrench. The tightening torque is 35-40 N·m, thus completing the fixing of the lightning rod mounting base 2; Furthermore, the lower end of the lightning rod 5 is vertically inserted into the lightning rod mounting hole 21 at the top of the lightning rod mounting base 2, and the verticality of the lightning rod 5 is adjusted to ensure that its axis is perpendicular to the horizontal plane with a deviation of no more than 1°. When locking, first screw the upper locking bolt 22 into the upper locking screw hole 221 and tighten it to 15-20 N·m with a torque wrench to ensure that the end is tightly pressed against the surface of the lightning rod 5; then screw the lower locking bolt 23 into the lower locking screw hole 231 and tighten it to 15-20 N·m to complete the fixed installation of the lightning rod 5. During disassembly, use a torque wrench to loosen the lower locking bolt 23 and the upper locking bolt 22 in sequence until the bolt ends are completely detached from the surface of the lightning rod 5. Then, hold the upper part of the lightning rod 5 with both hands and pull it vertically upward to complete the disassembly of the lightning rod 5. In addition, use a torque wrench to loosen the fixing bolt 4, remove the fixing bolt 4 from the bolt hole, and then remove the lightning rod mounting base 2 from the top plate 1 of the ship's mast to complete the disassembly of the mounting base.
[0018] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
