Description

Technical Field

[0001] This invention relates to a ship, specifically a valve box structure suitable for housing a tank cleaning valve on a ship, belonging to the field of ship design technology. Background Technology

[0002] Traditional tank cleaning pipes are typically placed within the base structure on the inner bottom. Before each tank cleaning operation, the manhole cover 2 on the side wall needs to be opened (e.g., Figure 1 As shown in the image, remove the tank cleaning hose for tank cleaning. Removing the hose through the manhole cover is inconvenient due to the narrowness of the manhole, and it also increases the risk of bumps and injuries. Summary of the Invention

[0003] The purpose of this invention is to provide a valve box structure suitable for housing tank cleaning valves on ships, changing the traditional tank cleaning valve housing method. While ensuring structural strength, the structure makes the arrangement of tank cleaning valves more convenient, facilitating crew members' use of the valves for tank cleaning.

[0004] The present invention adopts the following technical solution:

[0005] A valve box structure suitable for housing a tank washing valve on a ship is provided, wherein at least one valve box 4 is fixedly installed in the area between adjacent transverse bulkheads and adjacent longitudinal bulkheads B3 at the bottom of the ship's inner bottom; the valve box 4 is hexahedral in shape, with its front side flush with the first transverse bulkhead B1 and having a door; the tank washing valve is placed inside the valve box 4, and the water pipe at the rear end of the tank washing valve passes through a reserved hole on the second transverse bulkhead B2 and can shuttle along the reserved hole.

[0006] Preferably, the longitudinal bulkhead B3 is provided with a longitudinal bulkhead manhole, and the valve box 4 is positioned at a height that avoids the longitudinal bulkhead manhole.

[0007] Furthermore, a manhole is provided on the transverse bulkhead between some adjacent longitudinal bulkheads, and the position of the valve box 4 avoids the position of the transverse bulkhead between adjacent longitudinal bulkheads with the manhole.

[0008] Preferably, the valve box 4 has a hexahedral structure, wherein the bottom surface is an inclined plane.

[0009] Furthermore, the valve box 4 has a door 401 on the front, and below the door 401 is a baffle plate 402 to prevent the wash valve from sliding down.

[0010] Furthermore, the valve box 4 is positioned at a height of 1.5-1.7m above the inner bottom of the double-layer bottom, eliminating the need to remove the manhole cover during use.

[0011] Preferably, the side cross-section of the valve box 4 is a right-angled trapezoid.

[0012] Preferably, the valve box structure has multiple locations.

[0013] Furthermore, the valve box 4 is positioned at a height of 1.6m above the inner bottom of the double-layered bottom, which is adapted to the height of the operator when standing.

[0014] The beneficial effects of this invention are as follows:

[0015] 1) Provided that the transverse bulkhead structure meets the strength requirements, a valve box is installed at the bottom seat, and the tank washing valve is placed inside the valve box. When tank washing is required, the cover plate is opened and the tank washing pipe is removed.

[0016] 2) The valve box is located at a height of about 1.6m above the double bottom (adapted to human height), so there is no need to remove the manhole cover during use, making operation safe and convenient.

[0017] 3) The bottom surface of the valve box is set as a slope so that the tank washing valve automatically moves close to the box door, making it easy for the crew to access;

[0018] 4) The valve box has a baffle plate at the bottom of the door to prevent the washing valve from sliding down. This is a thoughtful design feature.

[0019] 5) A reserved hole is provided on the back plate of the valve box for the water supply pipe to pass through, so that the water pipe of the washing valve can be pulled out and retracted, and the storage reliability is better. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1 (Comparative Example):

[0030] See Figure 1-2 The tank cleaning pipes are located within the base structure on the inner bottom. Before each tank cleaning operation, the manhole cover 2 on the side wall needs to be opened (e.g., Figure 1 As shown in the image, remove the tank cleaning hose for tank cleaning. Removing the hose through the manhole cover is inconvenient due to the narrowness of the manhole, and it also increases the risk of bumps and injuries.

[0031] Example 1 is the prior art. Example

[0032] See Figure 3-7 A valve box structure suitable for housing tank washing valves on a ship, wherein at least one valve box 4 is fixedly installed in the area between adjacent transverse bulkheads and adjacent longitudinal bulkheads B3 at the bottom bench structure above the ship's inner bottom. Figure 4 As shown, Figure 5 The perspective only shows one longitudinal bulkhead, B3.

[0033] See Figure 5 The valve box 4 is hexahedral in shape, with its front side flush with the first transverse bulkhead B1 and equipped with a door. A tank washing valve is placed inside the valve box 4. The water pipe at the rear end of the tank washing valve passes through a pre-reserved opening in the second transverse bulkhead B2 and can travel along the pre-reserved opening. Figure 7 As shown.

[0034] See Figure 5 The longitudinal bulkhead B3 is provided with a longitudinal bulkhead manhole, and the valve box 4 avoids the longitudinal bulkhead manhole in height.

[0035] Furthermore, transverse bulkheads are provided on some of the transverse bulkheads between adjacent longitudinal bulkheads, and the valve box 4 is positioned to avoid the location of the transverse bulkheads between adjacent longitudinal bulkheads with transverse bulkhead manholes. The transverse bulkhead manholes are not shown in the accompanying drawings of this embodiment; please refer to the accompanying drawings of Embodiment 1. Figure 1 and 2 .

[0036] See Figure 5 and 7The valve box 4 has a hexahedral structure, with the bottom surface being an inclined plane.

[0037] See Figure 7 The valve box 4 has a door 401 on the front, and below the door 401 is a baffle plate 402 to prevent the wash valve from sliding down.

[0038] See Figure 4 The valve box 4 is positioned 1.6m above the inner bottom of the double-layered bottom, which is adapted to the operator's standing height. The manhole cover does not need to be removed during use.

[0039] See Figure 5 and 7 The side cross-section of the valve box 4 is a right trapezoidal shape.

[0040] See Figure 3 The valve box structure has multiple locations.

[0041] This invention, while ensuring the transverse bulkhead structure meets strength requirements, arranges a valve box at the bottom bench, housing the tank washing valve. When tank washing is needed, simply open the cover and remove the tank washing pipe. The valve box is positioned approximately 1.6m above the double bottom, eliminating the need to remove the manhole cover. Simply stand upright, open the valve box cover 5, and remove the tank washing pipe to perform the washing operation. The operation is safe and convenient.

[0042] like Figure 3-5 As shown, a valve box 4 structure is installed at a height of 2m above the double bottom. The center of the valve box is about 1.6m above the double bottom. When the tank needs to be washed, there is no need to open the manhole cover. Just open the door 401 of the valve box while standing normally and take out the tank washing pipe to wash the tank.

[0043] Key points: Without compromising structural strength, a valve box structure was designed at the bottom of the transverse bulkhead, simplifying the tank cleaning process and making it safer and more convenient for crew members. The structure is compact, does not affect structural strength, and makes efficient use of the space at the bottom of the transverse bulkhead. Considering the actual needs of the crew, when cleaning the tank, it is no longer necessary to open the manhole cover; only the valve box cover needs to be opened, simplifying the process and reducing the risk of crew injuries from bumps and knocks. The tank cleaning valve is neatly and aesthetically pleasingly housed within the valve box.

[0044] Without compromising structural strength, the valve box is positioned approximately 1.6 meters above the double bottom, facilitating crew operation. During tank washing, crew members no longer need to open manhole covers; simply opening the valve box cover suffices, simplifying the process and reducing the risk of injury from impacts. From a space utilization perspective, the valve box's placement also makes more efficient use of the space at the transverse bulkhead floor structure.

[0045] The above embodiment two is a preferred embodiment of the present invention. Those skilled in the art can make various changes or improvements on this basis. Without departing from the general concept of the present invention, these changes or improvements should fall within the scope of protection claimed by the present invention.
