DETAILED DESCRIPTION

[0014] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0015] See also Figure 1-3 An embodiment of the present utility model provides a novel marine diving ladder, comprising an upper ladder 1, a lower ladder 2, and a rotating member 3 for rotatably connecting the upper ladder 1 and the lower ladder 2.

[0016] The rotating member 3 includes an upper ladder rotating disk 31 connected to the bottom of the upper ladder 1, a lower ladder rotating disk 32 connected to the top of the lower ladder 2, and a rotating shaft 35 that rotatably connects the upper ladder rotating disk 31 and the lower ladder rotating disk 32. Specifically, a lower ladder rotating disk 32 is respectively provided at both ends of the top of the lower ladder 2, and the two lower ladder rotating disks 32 are connected by a rotating shaft 35. The rotating shaft 35 passes through the lower ladder rotating disk 32 and is rotatably connected to the upper ladder rotating disk 31 at both ends of the bottom of the upper ladder 1.

[0017] The upper ladder rotating disk 31 is provided with first rotating holes 33 at intervals along the annular edge, and the lower ladder rotating disk 32 is provided with a plurality of second rotating holes 34 at intervals along the circular edge. When the upper ladder rotating disk 31 rotates around the rotating shaft 35, the first rotating holes 33 and the second rotating holes 34 can overlap and correspond in sequence.

[0018] like Figure 1 As shown, the lower ladder 2 is now rotated upward around the rotation axis 35 until it fits in with the upper ladder 1. The working ladder is now in a folded state, making it easy to carry and lower toward the side of the ship. When it is needed, the lower ladder 2 can be rotated downward around the rotation axis 35 to spread the lower ladder 2 and the upper ladder 1 at a certain angle until the desired angle is reached. At this time, a first rotation hole 33 of the upper ladder rotating disk 31 coincides with a second rotation hole 34 of the lower ladder rotating disk 32. The fixing screw 36 is passed through the corresponding first rotation hole 33 and second rotation hole 34 to fix the angle at which the lower ladder 2 and the upper ladder 1 are spread. Figure 2 shown.

[0019] The upper end of the upper ladder 1 is provided with a plurality of locks 4, correspondingly located on either side. These locks 4 are used to secure cables to the ship's side railings. These locks 4 include a fixing bracket 41 and a cable connection hole 42 defined therein. The fixing bracket 41 comprises a base and brackets extending upward from either side of the base, with the cable connection holes 42 defined on opposite sides of the brackets. In this embodiment, the upper end of the upper ladder 1 is provided with four sets of locks 4 spaced apart, allowing for adjustment to accommodate the varying number and spacing of railings on different ships. During use, the cables are threaded through the cable connection holes 42 and locked to the railing, securing the ladder to the railing.

[0020] The lower ladder 2 includes a fixed ladder 21 and a sliding ladder 22 slidably connected to the fixed ladder 21. The relative sliding of the fixed ladder 21 and the sliding ladder 22 allows the lower ladder 2 to be extended or retracted according to different diving positions, facilitating operation and use. A handrail 5 is provided at the bottom of the lower ladder 2, specifically at the bottom of the sliding ladder 22. The handrail 5 allows crew members to firmly grasp the working ladder while diving along the working ladder, ensuring safety during operation and preventing falls.

[0021] The working principle of this utility model:

[0022] The initial state is Figure 1As shown, the upper ladder 1 and the lower ladder 2 are in a folded and stowed state. When it is necessary to launch the work, the work ladder can be taken out of the cabin, and then the lower ladder 2 is rotated outward to a certain angle according to the diving position. After reaching the required angle, the fixing screw 36 is passed through the corresponding first rotating hole 33 and the second rotating hole 34 to lock the upper ladder rotating disk 31 and the upper ladder rotating disk 32, so that the upper ladder 1 and the lower ladder 2 are maintained at the required angle; then, according to the diving position, the sliding ladder 22 is pulled out from the fixed ladder 21 until the lower ladder 2 is extended to the required length;

[0023] Finally, according to the number and spacing of the ship's railings, the corresponding lock 4 to be tied to the cable is selected, and the cable is passed through the cable connection hole on the lock 4 and tied to the railing. At this time, the crew can walk and dive along the upper ladder 1 and the lower ladder 2, and then grab the handrail 5 to clean the fishing net or debris.

[0024] The upper ladder 1 and the lower ladder 2 of the utility model can be adjusted to different angles through the rotating part 3 to meet different diving needs; the telescopic structure of the lower ladder 2 can realize direct access to the working ladder, and reach the designated location efficiently, quickly and conveniently, so as to carry out operations safely.

[0025] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention are intended to be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
