[0021] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0022] Embodiment 1

[0023] As Figure 1 、 2 shown in Figures 3 and 4, a small hatch anti-falling device for a ship provided in this embodiment includes a vertical frame (1) and an outer frame (9). The vertical frame (1) is vertically and fixedly installed on the outer frame (9). As Figure 2 shown, three sides of the outer frame (9) are straight, and the corners are smoothly transitioned. A frame beam (10) is provided on the outer frame (9), and a sleeve (8) is installed on the frame beam (10). The vertical frame (1) has a suitable height, and a handrail (2) is installed on the vertical frame (1). The vertical frame (1) is assembled with two handrails (2). The vertical frame (1) is perpendicular to the outer frame (9). The vertical frame (1) and the handrail (2) form an anti-falling guardrail. The handrail (2) is convenient for people to hold, and is safe and reliable.

[0024] It further includes a movable plate (6). The movable plate (6) is assembled with the sleeve (8) through a U-shaped shaft (7). After assembly, the movable plate (6) can rotate relative to the frame beam (10), and the movable plate (6) is restricted to rotate only towards the vertical frame (1), so that a channel is formed at the position of the outer frame (9) where the movable plate (6) rotates.

[0025] A plurality of locking plates (5) are provided on the side wall of the outer frame (9). Nuts (4) are installed on the locking plates (5). The anti-falling device is fixed at the small hatch through a fastening bolt passing through the locking plate (5) and the nut (4). As Figure 2 、 3 shown, the locking plates (5) are arranged in pairs on the side wall of the outer frame (9), and the paired locking plates (5) are respectively located on the inner side and the outer side of the outer frame (9). The locking plates (5) are assembled on the inner side and the outer side of the outer frame (9) and are arranged on three sides. The nuts (4) are welded to the locking plates (5). During use, the small hatch anti-falling device is fixed through the fastening bolt. After fastening, the structure is stable, safe and reliable, and the operation is convenient, playing an anti-falling role. It should be noted that holes are opened on the locking plates, and the hole diameters are the same as those of the nuts. The fastening bolts are screwed into the locking plates and the nuts to lock the small hatch anti-falling device. The anti-falling device has high safety and good anti-falling effect.

[0026] One end of the U-shaped shaft (7) of the shaft is connected to the movable plate (6), and the other end is assembled with the sleeve (8). After the sleeve (8) is assembled with the U-shaped shaft (7), the clearance between the U-shaped shaft (7) and the sleeve (8) is 2 mm, so that the movable plate (6) can rotate up and down after assembly. However, in order to prevent the movable plate (6) from rotating downward and the staff from falling, a cross beam (3) is also provided on the outer ring (9) of the skeleton. The cross beam (3) is installed inside the outer ring (9) of the skeleton, so that the cross beam (3) can limit the rotation of the movable plate (6) away from the vertical frame (1) and play a limiting role. Of course, it can also be considered that the movable plate (6) and the skeleton beam (10) are in the same plane, and the passage formed after the movable plate (6) rotates and opens allows one person to pass through.

[0027] In this embodiment, the U-shaped shaft is bent from an iron rod and installed on the sleeve and is not detachable. The U-shaped shaft and the sleeve are used in combination, so that the movable plate can rotate freely with the U-shaped shaft as the center. The height of the handrail is appropriate for convenient grasping by personnel. The movable plate and the vertical frame are arranged up and down. When personnel enter and exit, they open the movable plate, grasp the handrail, and close the movable plate, making it convenient and fast for personnel to enter and exit the hatch without being restricted by others, and it has strong versatility. The vertical frame and the handrail provide a grip for personnel to enter and exit the hatch. The protective device is half fixed and half movable, with a unique form and convenient for personnel to enter and exit. Compared with the existing anti-falling devices, this small hatch anti-falling device has a simple structure, is more user-friendly, has a better anti-falling effect, and can be reused in a cycle.

[0028] When specifically installing this anti-falling device, first place the small hatch anti-falling device at the installation position, make the locking plate fit tightly with the small hatch, insert the locking bolt into the locking plate and the nut, and slowly rotate the bolt with a wrench to make the bolt tightly connected to the small hatch. Repeat the above operation for the remaining locking plates to ensure that the bolt torque at the locking plate is uniform. Check whether the movable plate opens and closes smoothly, and then close the movable plate to complete the installation. When personnel enter the hatch, they hold the handrail (2), open the movable plate (6), enter the cabin, and then close the movable plate (6). When personnel exit the cabin, they open the movable plate (6), hold the handrail (2), exit the cabin, and then close the movable plate (6).

[0029] The above embodiments have described the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
