Water hose box and ro-ro passenger ship comprising same

Abstract

The invention provides a water hose box and a ro-ro passenger ship comprising the same, the water hose box is designed without a door, the water hose box comprises a main body frame, and the main body frame is of a U-shaped structure formed by long flat iron; the main body frame is divided into a rectangular space at the upper half part and a semicircular space at the lower half part, and the water hose is placed in the semicircular space at the lower half part of the main body frame after being wound. The problem that the water hose box is arranged in a ro-ro passenger ship, especially a loading cabin is solved, and the potential safety hazard problem caused by the fact that a traditional water hose box with a door cannot be opened is avoided.

Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, and specifically relates to a water hose box and a passenger roll-on / roll-off ship containing the water hose box. Background Technology

[0002] The existing hose boxes have doors, which can effectively protect the hoses inside from wind and rain erosion, making them suitable for outdoor use.

[0003] On passenger ro-ro ships or in the vehicle bays inside the PCTC (Public Transport Terminal), there are many vehicles parked. The dense arrangement of vehicles occupies a significant amount of space. When using the hose reels, crew members need to stand in front of the hose reel box and open the door to retrieve the hoses. The dense arrangement of vehicles obstructs the opening of the hose reel box doors, making it impossible to retrieve the hoses. Summary of the Invention

[0004] To address the problems existing in the prior art, this application proposes a water hose box, including a main frame, which is a U-shaped structure made of long flat iron; the main frame is divided into a rectangular space in the upper part and a semi-circular space in the lower part, and the water hose is placed in the semi-circular space in the lower part of the main frame after being rolled up.

[0005] Furthermore, the main frame is provided with guardrails made of short, flat iron on both sides of the lower semi-circular space.

[0006] Furthermore, the guardrail includes two short flat iron bars, one long and one short. The longer short flat iron bar corresponds to the diameter of the lower semicircular space of the main frame, and the shorter short flat iron bar corresponds to the radius of the lower semicircular space of the main frame and is perpendicular to the longer flat iron bar.

[0007] Furthermore, the diameter of the semi-circular space in the lower half of the main frame is larger than the diameter of the rolled-up water hose.

[0008] Furthermore, the upper half of the main frame has fixing devices on the opposite side walls of the rectangular space for fixing the nozzle and the valve wrench.

[0009] Furthermore, a connecting plate is vertically provided on the back of the main frame corresponding to the notch of the U-shaped structure, and the main frame is fixedly connected to the vertical wall surface by the connecting plate and bolts.

[0010] Furthermore, the surface of the water hose box is coated with red anti-rust paint.

[0011] A type of passenger roll-on / roll-off ship, which uses the aforementioned water hose with a container.

[0012] The water hose box provided by this invention has the following advantages over the prior art: This invention solves the problem of installing water hoses with boxes in the hold of passenger roll-on / roll-off ships, especially car loading ships, and avoids the safety hazards caused by the inability to open the doors of traditional water hoses with boxes. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of the present invention.

[0014] Figure 2 This is a schematic diagram illustrating the usage state of the present invention. Detailed Implementation

[0015] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] like Figure 1 and Figure 2 As shown, the water hose box proposed in this application is composed of a frame structure of flat iron and angle steel, with a square shape on top and a semi-circular shape on the bottom.

[0017] The hose is placed in the circular area below. A flat iron bar is installed in the circular area to prevent the hose from slipping. This allows for easy access to the hose at any time.

[0018] Fixing devices are installed on both sides of the directional area above the water hose box to secure the nozzles and valve wrenches.

[0019] A flat iron is installed at the back of the water hose box, and the water hose box is fixed with bolts and the flat iron.

[0020] In summary, these are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. All equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the specification are within the scope of the present invention.
