In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] This embodiment provides a fall prevention device, which is applied to a ship deck, wherein the deck has holes, and fasteners are arranged around the holes. Figure 1As shown, the device includes a base 10 and a cover assembly 20. The base 10 is arranged on the periphery of the hole. The base 10 is provided with a mounting hole 11. The fastener can pass through the mounting hole 11 to fix the base 10; the cover assembly 20 is arranged on the top of the base 10, and the cover assembly 20 includes a movable cover 21 and a fixed cover 22. The movable cover 21 has a covering position and a folding position. When the movable cover 21 is in the covering position, the cover assembly 20 can block the hole. When the movable cover 21 is in the folding position, the cover assembly 20 forms an operating hole connected to the hole, so that the workpiece can enter the hole.

[0034] In this device, a mounting hole 11 is provided on the base 10, and a fastener can pass through the mounting hole 11 and fix it on the periphery of the hole. When installing or removing, it is only necessary to twist the fastener without welding, thereby preventing damage to the deck, and the assembly and disassembly is simple and convenient to use. In addition, the cover assembly 20 includes a movable cover 21 and a fixed cover 22. When it is necessary to block the hole, it is only necessary to place the movable cover 21 in the covering position to block the hole, thereby preventing the operator from accidentally falling into the hole, thereby improving the safety of use. When it is necessary to place the workpiece in the hole, or to operate in the hole, it is only necessary to open the movable cover 21 and place it in the folding position. At this time, the cover assembly 20 forms an operating hole, which is connected to the hole. The operator can stand or squat on the fixed cover 22 to operate in the hole, solving the problem that the workpiece cannot enter the hole. The structure is simple and the operation is convenient.

[0035] It is worth noting that in this embodiment, the workpiece is an energy pipeline. When the movable cover plate 21 is in the folded position, the energy pipeline can be smoothly inserted into the hole, so as to facilitate the operator to work. In addition, the fastener is a bolt, which is more common and easy to install and disassemble. A plurality of holes are arranged on the deck, and a plurality of fasteners are arranged on the periphery of each hole. The corresponding base 10 is provided with a plurality of mounting holes 11 along its circumference. Each hole corresponds to a base 10, and each base 10 is fixed by a plurality of fasteners passing through the mounting hole 11, thereby ensuring the stability of the base 10.

[0036] It is further explained that since the base 10 is in a circular shape, if the mounting hole 11 is processed into a circular hole, it is not convenient to install and position the base 10. To solve this problem, Figure 1 and Figure 3 As shown, the mounting holes 11 are all waist holes. When the base 10 is mounted and positioned by fasteners, the structure of the waist holes facilitates the adjustment of the fasteners when mounting the base 10, thereby avoiding the problem of inconvenient installation. In addition, in this embodiment, there are four waist holes, which are evenly and spaced along the circumference of the base 10, thereby ensuring the uniformity of the force on the base 10. In other embodiments, other numbers of waist holes may be set, and the specific number is not limited in this embodiment.

[0037] like Figure 1 and Figure 4 As shown, the central angle of the movable cover plate 21 is 80°-100°. This structure can not only facilitate the folding of the movable cover plate 21, but also ensure that there is enough space for the energy pipeline to enter the hole when the movable cover plate 21 is in the folded position. It should be noted here that in this embodiment, the central angle of the movable cover plate 21 is 90°. In other embodiments, it can also be set to any degree between 80°-100°, as long as it can be conveniently folded and can provide a large enough space to pass the pipeline, and no other restrictions are made in this embodiment.

[0038] In addition, if Figure 1 As shown, the movable cover plate 21 and the fixed cover plate 22 are both mesh plates. This structure can reduce the weight of the cover plate assembly 20 to the greatest extent on the basis of ensuring the structural strength of the cover plate assembly 20, thereby facilitating installation and disassembly, and easy to carry. It should be noted here that in this embodiment, the mesh plates are all made of alloy steel, which has good rigidity and high hardness, and can improve safety. In addition, in order to further ensure the structural strength of the cover plate assembly 20, the cover plate assembly 20 is provided with a plurality of reinforcing ribs 40 along its radial direction. By providing a plurality of reinforcing ribs 40, the bending resistance of the cover plate assembly 20 can be ensured, thereby improving the safety of use.

[0039] In addition, it is worth noting that in this embodiment, two reinforcing ribs 40 are provided, and the two reinforcing ribs 40 are perpendicular to each other and cross-arranged, and this structure can maximize the structural strength of the cover assembly 20. At the same time, a rotating shaft 23 is provided at the intersection of the two reinforcing ribs 40, and the movable cover 21 is connected to the rotating shaft 23, so as to facilitate the installation of the cover assembly 20.

[0040] like Figure 2 As shown, the anti-fall device also includes a protective member 30, the inner periphery of the base 10 is connected to the bottom end of the protective member 30, and the cover assembly 20 is connected to the top end of the protective member 30. The protective member 30 can prevent the workpiece from falling into the hole from the gap between the base 10 and the cover assembly 20. In this structure, by providing the protective member 30, not only can the cover assembly 20 be conveniently installed on the top of the base 10 and the hole be covered, but the protective member 30 can also block the gap between the base 10 and the cover assembly 20, which can ensure that small parts or foreign objects on the deck fall into the hole through the gap, thus playing a good protective role.

[0041] like Figure 2As shown, the length of the guard 30 along its axial direction is 90mm-100mm, that is, the height along the vertical direction is 90mm-100mm. Within this range, not only the base 10 and the cover plate assembly 20 are installed at both ends of the guard 30, but also when the operator works on the fixed cover plate 22, it will not be too high above the deck, thereby ensuring the safety of the operator.

[0042] In addition, if Figure 1 and Figure 2 As shown, at least two handles 12 are also provided on the periphery of the base 10, and the at least two handles 12 are symmetrically arranged. The base 10 can be easily carried by providing the handles 12, and the at least two handles 12 are symmetrically arranged, which can improve the convenience and stability during carrying. In this embodiment, the specific number of the handles 12 is not limited, as long as it can ensure convenient carrying.

[0043] Finally, the use process of the anti-fall device in this embodiment is described in conjunction with the accompanying drawings:

[0044] First, the device is carried to the vicinity of the hole by the handle 12, and the base 10 is fixed to the periphery of the hole by using the fasteners of the deck through the mounting holes 11;

[0045] Secondly, when there is no operator, the movable cover plate 21 is placed in the covering position so that it covers the entire hole;

[0046] Finally, when an operator is required to operate, the movable cover 21 is opened and folded outward, and the energy pipeline is inserted into the hole to carry out the operation.

[0047] In summary, the use of the anti-fall device in this embodiment is not only convenient for installation and will not cause damage to the deck, but also ensures that the energy pipeline can be smoothly extended into the hole and can prevent the operator from falling into the hole.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
