[0002] A fire hose is a flexible pipe used for conveying water or extinguishing fires. It is usually made of durable materials such as rubber, polymer, or fabric-reinforced rubber. The fire hose can be connected to a water source and a sprinkler or nozzle, and water is conveyed to the target area through water pressure. The fire hose is generally stored inside a corresponding box. According to relevant specification requirements, fire hose boxes are conventionally required to be configured on the open decks of ships. This fire hose box is arranged near the fire hydrant and is used in conjunction with the fire hydrant to meet the fire fighting requirements of the ship.

Specific embodiments

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1: The present invention provides a technical solution: Please refer to Figures 1 - 2 , a protection device for a fire hose box on an open deck of a ship, including a protection box 1 and a cover plate 2. Two groups of connecting plates 3 are fixedly connected to the outer surface of the left side of the protection box 1. The number of each group of connecting plates 3 is two. A pin shaft 4 is movably inserted into the outer surface of each group of connecting plates 3. A split pin 24 is inserted into the opening of the pin shaft 4. A ball joint bolt 5 is sleeved between the two connecting plates 3. Two lapping plates 7 are fixedly connected to the outer surface of the front side of the cover plate 2 near the left end. A through groove for the ball joint bolt 5 to pass through is opened on the outer surface of the lapping plate 7. A wing nut 6 is threadedly connected to the outer surface of the ball joint bolt 5. One end of the wing nut 6 is attached to the outer surface of the front side of the lapping plate 7. The protection box 1 and the cover plate 2 are both made of carbon structural steel. The cost of carbon structural steel is low, it is easy to produce and process, and the strength of carbon structural steel is high. When the fire hose box needs to be used, the user unscrews the wing nut 6 so that the wing nut 6 disengages from the outer surface of the ball joint bolt 5, thereby removing the limit on the lapping plate 7.

[0034] Please refer to Figure 1 , Figure 3 and Figure 4, two sets of side plates 8 are fixedly connected to the right outer surface of the protective box 1. The number of each set of side plates 8 is two. Connecting bolts 9 penetrate through the outer surfaces of each set of side plates 8. Two rotating plates 10 are fixedly connected to the outer surface of the front side of the cover plate 2 near the right end. The rotating plates 10 are rotatably sleeved on the outer surface of the connecting bolts 9 between the two side plates 8. A connecting nut 11 is threadedly connected to the bottom outer surface of the connecting bolt 9. The top outer surface of the connecting nut 11 is in contact with the lower side plate 8. A handle 28 is fixedly connected to the outer surface of the cover plate 2. After the limit of the cover plate is released, pull the handle 28. The handle 28 drives the cover plate 2, so that the cover plate 2 is opened. When the cover plate 2 is opened, it drives the rotating plates 10 to rotate between the two side plates 8, so that the user can quickly open the cover plate 2, and then use the fire hose box.

[0035] Please refer to Figure 6 , four fixing screw holes 27 are opened on the rear outer surface of the protective box 1. The four fixing screw holes 27 are adapted to the openings provided by the hose box itself. Align the fixing screw holes 27 with the openings provided by the hose box itself, and then screw the fixing bolts into the fixing screw holes 27 to fix the hose box and the protective box 1.

[0036] Please refer to Figure 4 , gaskets 23 are provided between the head of the connecting bolt 9 and the upper side plate 8, between the rotating plate 10 and the side plate 8, and between the connecting nut 11 and the lower side plate 8. A plurality of gaskets 23 are all sleeved on the outer surface of the connecting bolt 9. Through the gaskets 23, the friction area can be increased, the common point of the fastening force can be increased, the fastening effect can be improved, and the buffering effect between the rotating plate 10 and the side plate 8 can be increased.

[0037] Please refer to Figure 2 , a rectangular groove is opened on the outer surface of the overlapping plate 7. The width of the rectangular groove is greater than the diameter of the screw rod of the articulated bolt 5. By providing the rectangular groove, when the cover plate 2 drives the overlapping plate 7 to move, the rectangular groove provides a channel for the articulated bolt 5, avoiding the overlapping plate 7 being unable to rotate due to being blocked by the articulated bolt 5.

[0038] In the specific implementation process, such as Figures 1 - 6, align the opening provided with the fire hose box with the fixing screw holes 27 on the back of the protection box 1, then screw the fixing bolts into the fixing screw holes 27 to fix the fire hose box inside the protection box 1. When the ship is sailing normally, the wave-facing cover plate 2 is closed, which well protects the fire hose box inside the protection box 1. When it is necessary to use the fire hose box, the user unscrews the wing nut 6 so that the wing nut 6 disengages from the outer surface of the loose joint bolt 5, thereby releasing the limit on the overlapping plate 7. After releasing the limit on the two overlapping plates 7, the user pulls the handle 28, and the handle 28 drives the cover plate 2 to open. When the cover plate 2 opens, it drives the rotating plate 10 to rotate between the two side plates 8, so that the user can quickly open the cover plate 2 and thus use the fire hose box.

[0039] Embodiment 2: In Embodiment 1, there is still a problem that the protection box 1 cannot be installed at any position on the ship's railing according to actual needs. Therefore, on the basis of Embodiment 1, it further includes:

[0040] Please refer to Figure 6 and Figure 7 , two longitudinal beams 12 are fixedly connected to the outer surface of the rear side of the protection box 1. The inner surfaces of the two longitudinal beams 12 are both rotatably connected with a left-right threaded screw rod 13. The left-right threaded screw rod 13 rotates through the outer surface of the top of the longitudinal beam 12. A knob 14 is fixedly connected to the outer surface of the top of the left-right threaded screw rod 13. Two threaded blocks 15 are threadedly connected to the outer surface of the left-right threaded screw rod 13. Connecting blocks 16 are fixedly connected to the outer surfaces of the two threaded blocks 15. The connecting blocks 16 extend to the outer surface of the longitudinal beam 12. Vertical plates 17 are fixedly connected to the outer surfaces of the two connecting blocks 16 away from the threaded blocks 15. Hooks 18 are fixedly connected to the outer surfaces of the two vertical plates 17 away from the connecting blocks 16. According to the distance between the upper and lower rails of the railing of different ships, rotate the knob 14. The knob 14 drives the left-right threaded screw rod 13 to rotate. The left-right threaded screw rod 13 drives the two threaded blocks 15 to move towards or away from each other, thereby driving the connecting blocks 16 to make the vertical plates 17 drive the upper and lower hooks 18 to move, so as to adjust the distance between the upper and lower hooks 18.

[0041] Please refer to Figure 7 , a chute is opened on the outer surface of the longitudinal beam 12. The connecting block 16 is movably connected to the inner wall of the chute. The chute provides a channel for the movement of the connecting block 16, and when the left-right threaded screw rod 13 rotates to drive the threaded block 15 to move, the connecting block 16 slides inside the chute, avoiding the rotation of the threaded block 15 along with the rotation of the left-right threaded screw rod 13.

[0042] In the specific implementation process, such as Figure 6 , Figure 7 and Figure 10, when installing the protection box 1, according to the spacing between the upper and lower railings of the fence of different ships, turn the knob 14. The knob 14 drives the forward and reverse screw rod 13 to rotate. The forward and reverse screw rod 13 drives the two threaded blocks 15 to move towards or away from each other, thereby driving the connecting block 16, so that the vertical plate 17 drives the hook 18 in the up and down direction to move, so as to adjust the distance between the upper and lower hooks 18 to make it suitable for the ship fences with different spacings. The protection box 1 is hung on the fence through the hook 18, so that the installation position on the fence can be arbitrarily selected as needed.

[0043] Embodiment 3: In Embodiment 2, there is still a phenomenon that when the hook 18 is hung on the fence, it is easily affected by external forces and causes the protection box 1 to shake. Therefore, on the basis of Embodiment 2, it further includes:

[0044] Please refer to Figure 8 and Figure 9 , on the outer surface of the side of the hook 18 away from the vertical plate 17, an L-shaped limiting plate 19 is hinged through a hinge. A regulating screw 20 is threaded through the outer surface of the right side of the L-shaped limiting plate 19. One side of the regulating screw 20 facing the inside of the hook 18 is rotatably connected with an arc-shaped clamping plate 21. Rotate the regulating screw 20 so that the regulating screw 20 drives the arc-shaped clamping plate 21 to move, so that the arc-shaped clamping plate 21 cooperates with the arc part of the hook 18 to clamp the pull rod of the fence, so that the protection box 1 is fixed on the railing more firmly, preventing the hook 18 from shaking due to the appearance of a gap at the railing under external force.

[0045] Please refer to Figure 8 and Figure 9 , on the outer surface of the bottom end of the L-shaped limiting plate 19 and the outer surface of the left side of the hook 18, corresponding limiting screw holes are opened. A limiting bolt 22 is threadedly connected inside the limiting screw hole. Under the action of the hinge, the L-shaped limiting plate 19 can rotate. At this time, rotate the limiting screw hole at one end of the L-shaped limiting plate 19 to the corresponding limiting screw hole on the hook 18, and then screw the limiting bolt 22 into the limiting screw hole to limit the L-shaped limiting plate 19.

[0046] Please refer to Figure 8 and Figure 9 , two limiting rods 26 are movably inserted into the outer surface of the right side of the L-shaped limiting plate 19. The other sides of the two limiting rods 26 are fixedly connected with the outer surface of the arc-shaped clamping plate 21. When the regulating screw 20 rotates, it drives the arc-shaped clamping plate 21 to move. At this time, it drives the limiting rods 26 to move on the surface of the L-shaped limiting plate 19, preventing the arc-shaped clamping plate 21 from rotating as the regulating screw 20 rotates.

[0047] Please refer to Figure 8 and Figure 9The inside of the arc of the hook 18 and the outside of the arc clamping plate 21 are fixedly connected with a silicone pad 25. The function of the silicone pad 25 is to increase the friction between the hook 18 and the arc clamping plate 21 and the railing, and the silicone pad 25 can be deformed to a certain extent, so that the clamping of the railing is more stable.

[0048] In the specific implementation process, Figure 8 , Figure 9 and Figure 10 , rotate the L-shaped limit plate 19. Under the action of the hinge, the L-shaped limit plate 19 can rotate. At this time, the limit screw hole at one end of the L-shaped limit plate 19 is rotated to the corresponding limit screw hole on the hook 18, and then the limit bolt 22 is screwed into the limit screw hole to limit the L-shaped limit plate 19. Then the adjusting screw 20 is rotated so that the adjusting screw 20 drives the arc-shaped clamping plate 21 to move, so that the arc-shaped clamping plate 21 cooperates with the arc-shaped part of the hook 18 to clamp the pull rod of the fence, so that the protection box 1 is fixed more firmly on the railing to prevent the gap between the hook 18 and the railing from shaking due to external force.

[0049] Specifically, the working principle of the utility model is as follows:

[0050] During actual use of the utility model, the opening of the fire hose box is matched with the fixing screw hole 27 on the back of the protection box 1, and the fixing bolt is screwed into the fixing screw hole 27 to fix the fire hose box inside the protection box 1. When the ship is sailing normally, the wave-facing cover plate 2 is closed, which well protects the fire hose box inside the protection box 1. When the fire hose box needs to be used, the user unscrews the butterfly nut 6 to disengage the butterfly nut 6 from the outer surface of the live bolt 5, thereby releasing the limit on the lap plate 7. After the limit on the two lap plates 7 is released, the user pulls the handle 28, and the handle 28 drives the cover plate 2 to open. When the cover plate 2 is opened, it drives the rotating plate 10 to rotate between the two side plates 8, so that the user can quickly open the cover plate 2 to use the fire hose box.

[0051] When installing the protection box 1, according to the spacing between the upper and lower railings of the fence of different ships, the knob 14 is turned, and the knob 14 drives the forward and reverse screw rods 13 to rotate, and the forward and reverse screw rods 13 drive the two threaded blocks 15 to move towards or away from each other, thereby driving the connecting block 16 so that the vertical plate 17 drives the hook 18 to move in the up and down directions, thereby adjusting the distance between the upper and lower hooks 18 to make it suitable for ship fences with different spacings. The protection box 1 is hung on the fence through the hooks 18, so that the position on the fence can be arbitrarily selected according to needs.

[0052] In order to prevent the protection box 1 from shaking when the hook 18 is hung on the fence, the L-shaped limiting plate 19 can be rotated. Under the action of the hinge, the L-shaped limiting plate 19 can rotate. At this time, the limiting screw hole at one end of the L-shaped limiting plate 19 is rotated to the corresponding limiting screw hole on the hook 18, and then the limiting bolt 22 is screwed into the limiting screw hole to limit the L-shaped limiting plate 19. Then, the adjusting screw 20 is rotated, so that the adjusting screw 20 drives the arc-shaped clamping plate 21 to move, so that the arc-shaped clamping plate 21 cooperates with the arc-shaped part of the hook 18 to clamp the pull rod of the fence, so that the protection box 1 is fixed on the railing more firmly, preventing the hook 18 from having a gap at the railing and shaking when subjected to external force.

[0053] In summary, the utility model can effectively protect the fire hose box and can install the protection device at a suitable position according to different actual needs.

[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
