Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of protective device, specifically is a deck protective device for ship. BACKGROUND

[0002] The deck of the general civilian ship is paved with rubber pad, which plays a role in protecting the deck.

[0003] In the field of naval ships, during the sea shooting training, the shell withdrawn by the machine gun has a huge counterforce, which may cause damage to the deck of the ship or other nearby equipment, so a protective net is generally arranged under the gun for catching the shell and preventing the shell from damaging the deck.

[0004] However, the current deck protective net has the following problems: (1) the height cannot be adjusted, so the height of the protective net cannot be adjusted according to the height of the gun, thereby causing insufficient buffer distance; (2) the connection between the protective net and the support structure is not stable enough, and the protective net is prone to loosen under the impact of the shell; (3) only one layer of protective net is arranged, and if the number of shells is large, the protective net may be crushed, failing to achieve the protective effect. TECHNICAL SOLUTION

[0005] In view of the deficiencies of the prior art, the utility model provides a deck protective device for ship to solve the problems mentioned in the background.

[0006] To solve the above technical problems, the utility model provides the following technical scheme:

[0007] A deck protective device for ship, comprising a support mechanism, a first protective net mounted on the support mechanism, and a second protective net mounted on the support mechanism and located below the first protective net, wherein the support mechanism comprises four hydraulic cylinders arranged in a rectangular shape, a U-shaped seat connected to the telescopic ends of the hydraulic cylinders, and positioning rods fixed in the U-shaped seat and arranged alternately in an up-down direction; the four corners of the first protective net are connected with first rope belts, and the first rope belts are sequentially wound around all the positioning rods from the inside to the outside and then bound to the outermost positioning rod.

[0008] Preferably, clamps are clamped on the cylinders of the hydraulic cylinders, opposite surfaces of two clamps in the same row are rotatably connected with rotating rods, the rotating rods are connected with lifting rings, the four corners of the second protective net are connected with second rope belts, and the second rope belts are bound to the corresponding lifting rings.

[0009] The above technical scheme fixes the second protective net through the second rope belts bound to the lifting rings, the lifting rings are connected to the rotating rods, the rotating rods can rotate along the clamps, and therefore the direction of the lifting rings can be adjusted for the connection of the second rope belts. When the clamps are loosened, the position of the clamps on the hydraulic cylinders can be adjusted, thereby adjusting the height of the second protective net.

[0010] The bottom of the hydraulic cylinder is connected with a mounting plate, and a mounting hole is formed in the mounting plate.

[0011] The mounting plate is mounted on the deck through bolts, and the first protective net is located below the fort.

[0012] Preferably, the first protective net and the second protective net are both woven by flame-retardant polyester fibers.

[0013] Due to the high temperature of the shell, the protective net is made of flame-retardant material, which can prevent the protective net from catching fire.

[0014] Preferably, the mesh size of the first protective net is smaller than that of the second protective net.

[0015] The above technical solution can prevent all the shells from being concentrated on one protective net, effectively preventing the protective net from falling off due to the large weight.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] Through the work of the hydraulic cylinder, the height of the first protective net can be adjusted, so as to adapt to the fort of different heights. The first rope belt is wound around the positioning rod and then bound on the positioning rod, which increases the connection force between the first rope belt and the positioning rod, prevents the first protective net from being separated from the positioning rod under the impact of the shell, and improves the stability.

[0018] By setting the second protective net below the first protective net, that is, setting two layers of protective nets, the buffering of the shell can be increased, and the damage to the deck can be reduced. BRIEF DESCRIPTION OF DRAWINGS

[0023] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts under the premise that no creative efforts are made, belong to the scope of protection of the present application. Embodiment 1

[0024] Please refer to Figures 1-2 A ship deck protection device, comprising a supporting mechanism, a first protection net 1 installed on the supporting mechanism, a second protection net 2 installed on the supporting mechanism and below the first protection net, the first protection net 1 and the second protection net 2 are both woven by flame-retardant polyester fibers. Because the shell temperature is high, the protection net adopts flame-retardant material, which can prevent the protection net from catching fire.

[0025] The supporting mechanism comprises four hydraulic cylinders 3 arranged in a rectangular shape, a U-shaped seat 4 connected to the telescopic ends of the hydraulic cylinders, positioning rods 5 fixed in the U-shaped seat and arranged alternately in an up-down direction, and a mounting plate 11 connected to the bottom of the hydraulic cylinder 3, wherein mounting holes are formed in the mounting plate 11, and the mounting plate 11 is installed on the deck by bolts, and the first protection net 1 is located below the gun emplacement. By the working of the hydraulic cylinder 3, the height of the first protection net 1 can be adjusted, so as to adapt to gun emplacements of different heights.

[0026] The four corners of the first protection net 1 are connected with first rope belts 6, and the first rope belts 6 are sequentially wound around all the positioning rods 5 from the inside to the outside and then tied to the outermost positioning rod 5. The first protection net 1 is wound around the positioning rods 5 by the first rope belts 6 and then tied to the positioning rods 5, which increases the connection force between the first rope belts 6 and the positioning rods 5, prevents the first protection net from being separated from the positioning rods under the impact of the shell, and improves the stability.

[0027] The cylinder body of the hydraulic cylinder 3 is clamped with a clamp 7, the opposite surfaces of the two clamps 7 in the same row are rotatably connected with a rotating rod 8, the rotating rod 8 is connected with a lifting ring 9, the four corners of the second protection net 2 are connected with second rope belts 10, and the second rope belts 10 are tied to the corresponding lifting rings 9. The second protection net 2 is tied to the lifting rings 9 by the second rope belts 10, so as to fix the second protection net 2, the lifting rings 9 are connected to the rotating rods 8, the rotating rods 8 can rotate along the clamps 7, and therefore the direction of the lifting rings 9 can be adjusted for the connection of the second rope belts 10. When the clamps 7 are loosened, the position of the clamps 7 on the hydraulic cylinder 3 can be adjusted, so as to adjust the height of the second protection net 2.

[0028] By arranging the second protection net 2 below the first protection net 1, i.e. arranging two layers of protection nets, the buffer for the shell can be increased, and the damage to the deck can be reduced. Embodiment 2

[0029] On the basis of the embodiment 1, the mesh size of the first protective net 1 is smaller than the mesh size of the second protective net 2. The bullet shell with large volume is left on the first protective net 1, and the bullet shell with small volume is dropped on the second protective net 2, so as to avoid that all bullet shells are concentrated on one protective net, and effectively prevent the protective net from falling off due to large weight.
