Drainage system of ro-ro ship deck and ro-ro ship

Abstract

This invention belongs to the field of marine technology and discloses a drainage system for a ro-ro ship deck and the ro-ro ship itself. The drainage system for the ro-ro ship deck connects longitudinal and transverse drainage channels below the vehicle deck, and a sewage well is connected to the longitudinal and / or transverse drainage channels. During cleaning, sewage flows into the drainage channels through the nearest drain outlet and is quickly guided to the sewage well. Sewage no longer flows freely on the deck surface, reducing accumulation and retention on the vehicle deck and preventing sewage from adhering to the deck surface and bulkhead corners after drying, thus reducing the difficulty of cleaning operations. Due to the multiple drain outlets, cleaning can be carried out more efficiently, reducing the time and effort required and improving cleaning efficiency. Furthermore, the cleaning structure effectively removes dirt from the corresponding drainage channels, ensuring drainage effectiveness and further improving cleaning quality and efficiency.

Description

Technical Field

[0001] This invention relates to the field of technical ships, and more particularly to drainage systems for roll-on / roll-off (Ro-Ro) ship decks and Ro-Ro ships. Background Technology

[0002] Currently, there is an increasing number of cases involving full truckload transportation and full truckload transportation with cargo, especially in short-distance sea freight. Cargo trucks are often driven directly onto roll-on / roll-off ships. These vehicles are different from new cars used to transport goods, as their wheels carry a large amount of mud, sewage and other impurities from the journey.

[0003] Existing roll-on / roll-off (Ro-Ro) ships often use large sewage wells in the corners of the vehicle deck (usually near the bow and stern). The cleaning of the deck surface relies on the ship's own rolling and pitching motions during operation, as well as the crew's use of high-pressure water jets after the ship arrives at port. However, because the sewage wells are only located at the bow and stern, sewage flows throughout the deck before entering the wells, making it difficult to clean thoroughly during operation. This results in incomplete cleaning. After drying, the sewage tends to adhere to the deck surface and the corners of the bulkheads, making it difficult to remove. Furthermore, cleaning from the middle of the cargo hold to the sewage wells at the bow and stern requires a large amount of work and expends considerable effort from the crew to wash the deck surface, resulting in low cleaning efficiency.

[0004] Therefore, there is an urgent need for a drainage system for the deck of a roll-on / roll-off (Ro-Ro) ship and a Ro-Ro ship itself to solve the problems in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a drainage system for the deck of a roll-on / roll-off ship, which can improve the cleaning efficiency of the vehicle deck.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The drainage system of a roll-on / roll-off (Ro-Ro) ship deck includes:

[0008] The vehicle deck has a longitudinal drainage channel and a transverse drainage channel underneath it. The longitudinal drainage channel is connected to the transverse drainage channel. The vehicle deck has a number of drainage outlets corresponding to the longitudinal drainage channel and the transverse drainage channel.

[0009] A sewage well is provided on the vehicle deck, and the longitudinal drainage channel and / or the transverse drainage channel are connected to the sewage well;

[0010] The cleaning structure is provided on the vehicle deck at the top of both the longitudinal and transverse drainage channels. The cleaning structure is used to clean the dirt in the corresponding drainage channels.

[0011] Optionally, along the first direction, a longitudinal drainage channel is provided on each side of the vehicle deck, and a plurality of transverse drainage channels are spaced apart between two longitudinal drainage channels along the first direction. The extension direction of the longitudinal drainage channels is perpendicular to the transverse drainage channels, and the two ends of each transverse drainage channel are respectively connected to two longitudinal drainage channels.

[0012] Optionally, the vehicle deck is provided with sewage wells at the bow, middle and stern, and each sewage well is connected to the longitudinal drainage channel and / or the transverse drainage channel.

[0013] Optionally, the longitudinal drainage channel includes bulb flat steel and angle steel. The bulb flat steel is arranged vertically below the vehicle deck. One side plate of the angle steel is vertically welded to the side of the bulb flat steel, and the other side plate of the angle steel is vertically welded to the lower surface of the vehicle deck.

[0014] Optionally, the transverse drainage channel includes a channel steel, and the top ends of the two channel walls of the channel steel are welded to the lower surface of the vehicle deck.

[0015] Optionally, the vehicle deck is provided with longitudinal stiffeners, and the longitudinal stiffeners are provided with assembly slots corresponding to the positions of the channel steel, with the channel steel disposed in the assembly slots.

[0016] Optionally, the connection between the bottom wall and the side wall of the assembly groove is chamfered.

[0017] Optionally, the cleaning structure includes a cleaning port and a grating plate. The cleaning port is provided on the vehicle deck at the top of both the longitudinal drainage channel and the transverse drainage channel. The grating plate is installed over the cleaning port and is detachably connected to the vehicle deck.

[0018] Optionally, the width of the cleaning port is greater than the width of the longitudinal drainage channel, and the width of the cleaning port is greater than the width of the transverse drainage channel.

[0019] The purpose of this invention is to provide a roll-on / roll-off (Ro-Ro) ship that enables crew members to more effectively clean dirt and sewage on the deck, improving cleaning efficiency and effectively maintaining the cleanliness of the vehicle deck of the Ro-Ro ship.

[0020] To achieve this objective, the present invention adopts the following technical solution:

[0021] Ro-Ro ships, including the drainage system of the aforementioned ro-ro ship deck.

[0022] Beneficial effects:

[0023] The drainage system for the roll-on / roll-off (Ro-Ro) ship deck provided by this invention features longitudinal and transverse drainage channels connected beneath the vehicle deck, with a sewage well connected to both channels. During cleaning, sewage flows into the drainage channels via the nearest outlet and is quickly guided to the sewage well, preventing it from flowing freely on the deck surface. This reduces sewage accumulation and retention on the vehicle deck, avoiding the problem of dried sewage adhering to the deck surface and bulkhead angles, thus reducing the difficulty of cleaning operations. The multiple drainage outlets allow for more efficient cleaning, reducing time and effort required and improving cleaning efficiency. Furthermore, the vehicle deck at the top of both the longitudinal and transverse drainage channels is equipped with cleaning structures. When mud or impurities clog the channels, crew members can quickly open these structures to remove debris, ensuring effective drainage and further improving cleaning quality and efficiency.

[0024] The ro-ro ship provided by this invention includes the aforementioned drainage system for the ro-ro ship deck, which enables the crew on the ro-ro ship to more effectively clean dirt and sewage on the deck, improves cleaning efficiency, effectively maintains the cleanliness of the vehicle deck of the ro-ro ship, and improves the operational efficiency of maritime transport of whole vehicles and cargo, while reducing the time and effort costs of cleaning operations.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0042] This embodiment provides a drainage system for the deck of a roll-on / roll-off ship, such as... Figures 1-9 As shown, the drainage system of the roll-on / roll-off ship deck includes a vehicle deck 100, a drainage access point, and a cleaning structure 300. The vehicle deck 100 is provided with a longitudinal drainage channel 110 and a transverse drainage channel 120, which are connected. The vehicle deck 100 has several drainage outlets 130 corresponding to the longitudinal drainage channel 110 and the transverse drainage channel 120. A sewage well 200 is provided on the vehicle deck 100. The longitudinal drainage channel 110 and / or the transverse drainage channel 120 are connected to the sewage well 200. The cleaning structure 300 is provided on the vehicle deck 100 at the top of the longitudinal drainage channel 110 and the transverse drainage channel 120. By opening the cleaning structure 300, the crew can clean the dirt in the corresponding drainage channel.

[0043] The drainage system of this roll-on / roll-off ship deck connects longitudinal drainage channels 110 and transverse drainage channels 120 below the vehicle deck 100, and the sewage well 200 is connected to the longitudinal drainage channels 110 and / or the transverse drainage channels 120. During the cleaning process, sewage flows into the drainage channels through the drain outlet 130 and is quickly guided into the sewage well 200. Sewage no longer flows freely on the deck surface, reducing accumulation and retention on the vehicle deck 100. This avoids the problem of sewage adhering to the deck surface and the corners of the bulkheads after drying, thus reducing cleaning costs. The difficulty of the operation; due to the setting of multiple drainage outlets 130, the cleaning work can be carried out more efficiently, thereby reducing the time and effort required for cleaning and improving cleaning efficiency; and the vehicle deck 100 at the top of the longitudinal drainage channel 110 and the transverse drainage channel 120 are equipped with cleaning structures 300. When mud and impurities are encountered in the longitudinal drainage channel 110 and the transverse drainage channel 120, the crew can quickly open the cleaning structure 300 to clean the dirt in the corresponding drainage channel, ensuring the drainage effect and further improving the cleaning quality and cleaning efficiency.

[0044] Optionally, such as Figure 1As shown, along the first direction, a longitudinal drainage channel 110 is provided on each side of the vehicle deck 100, and several transverse drainage channels 120 are spaced apart between two longitudinal drainage channels 110 along the first direction. The extension direction of the longitudinal drainage channels 110 is perpendicular to the transverse drainage channels 120, and both ends of each transverse drainage channel 120 are connected to two longitudinal drainage channels 110 respectively. By providing longitudinal drainage channels 110 on each side of the vehicle deck 100 and spaced apart between two longitudinal drainage channels 110, the number and density of drainage channels are increased. Regardless of where the sewage is generated on the ro-ro ship deck, there is a relatively close drainage channel, thereby reducing the difficulty of cleaning operations and helping to guide sewage to the sewage well 200 more quickly, reducing the chance of sewage lingering on the deck. Furthermore, because the drainage channels are denser and more evenly distributed, cleaning work can be carried out more quickly and orderly, improving cleaning efficiency.

[0045] Optionally, such as Figure 1 As shown, the vehicle deck 100 is equipped with sewage wells 200 at its bow, midsection, and stern, each sewage well 200 communicating with a longitudinal drainage channel 110 and / or a transverse drainage channel 120. Specifically, the sewage wells 200 at the bow and stern of the vehicle deck 100 are located at opposite ends of the longitudinal drainage channel 110, while the sewage well 200 in the midsection of the vehicle deck 100 is located at the intersection of the longitudinal drainage channel 110 and the transverse drainage channel 120. By placing sewage wells 200 at different locations on the vehicle deck 100, the coverage area is wider, and sewage generated in any part of the vehicle deck 100 can be quickly guided to the corresponding sewage well 200, helping to ensure that the entire surface of the vehicle deck 100 can be effectively cleaned. The placement of the sewage well 200 in the midsection of the vehicle deck 100 makes cleaning operations more convenient, as crew members can access the sewage well 200 more closely for cleaning, without having to move sewage a long distance to the sewage wells 200 at the bow and stern, thus improving cleaning efficiency.

[0046] Optionally, such as Figures 2-3 As shown, the longitudinal drainage channel 110 includes a bulb flat steel 111 and an angle steel 112. The bulb flat steel 111 is vertically positioned below the vehicle deck 100. One sidewall of the angle steel 112 is vertically welded to the side of the bulb flat steel 111, and the other sidewall of the angle steel 112 is vertically welded to the lower surface of the vehicle deck 100, thereby forming the longitudinal drainage channel 110. This ensures that the longitudinal drainage channel 110 structure is more robust, and the durability and reliability of the drainage system are improved.

[0047] Optionally, such as Figures 4-5As shown, the transverse drainage channel 120 includes a channel steel 121, the top ends of which are welded to the lower surface of the vehicle deck 100. The use of the channel steel 121 provides the transverse drainage channel 120 with a robust structure, enabling it to effectively collect and guide sewage, prevent sewage from accumulating on the deck, and improve drainage efficiency.

[0048] Optionally, a longitudinal stiffener 140 is provided under the vehicle deck 100, and an assembly groove 141 is provided on the longitudinal stiffener 140 corresponding to the position of the channel steel 121, with the channel steel 121 disposed within the assembly groove 141. The use of the longitudinal stiffener 140 provides additional support for the drainage system, ensuring the structural stability of the drainage system. Specifically, by installing the channel steel 121 within the assembly groove 141, the vibration and displacement of the channel steel 121 are reduced, which helps maintain the positional stability of the channel steel 121 and ensures smooth drainage.

[0049] Optionally, a chamfer 142 is provided at the connection between the bottom wall and the side wall of the assembly groove 141. The chamfer 142 at the connection between the bottom wall and the side wall of the assembly groove 141 helps reduce stress concentration at the connection point, increasing material durability and reducing fatigue and damage that may result from stress concentration. The chamfer 142 also makes it easier for the channel steel 121 to slide into the assembly groove 141, thereby simplifying the installation process of the drainage system, accelerating installation, and reducing labor costs.

[0050] Optionally, such as Figures 6-9 As shown, the cleaning structure 300 includes a cleaning port 310 and a grating plate 320. Cleaning ports 310 are provided on the vehicle deck 100 at the top of both the longitudinal drainage channel 110 and the transverse drainage channel 120. The grating plate 320 covers the cleaning ports 310 and is detachably connected to the vehicle deck 100. Due to the grating plate 320, larger debris such as gravel and wood chips are less likely to enter the drainage system, avoiding the risk of blockage and damage. However, wastewater can easily enter the drainage channel through the grating plate 320, helping to keep the drainage channel unobstructed. Even if the drainage channel is blocked by debris, the crew can simply open the grating plate 320 and clean the debris through the cleaning port 310. This makes cleaning easier for the crew, reducing the complexity and time required for cleaning work.

[0051] The design of the drain outlet 310 and the grating 320 enhances cleaning efficiency, reduces the risk of dirt entering the drainage system, provides a detachable connection, and reduces the complexity of cleaning work, thereby improving the performance and maintenance of the drainage system.

[0052] Optionally, the width of the cleaning port 310 is greater than the width of the longitudinal drainage channel 110, and the width of the cleaning port 310 is greater than the width of the transverse drainage channel 120. The wider cleaning port 310 provides a larger working area, which helps to clean debris in the sewage tank more effectively, including larger gravel and dirt, simplifying the cleaning operation process and improving cleaning efficiency.

[0053] This embodiment also provides a roll-on / roll-off (Ro-Ro) ship, which includes the aforementioned drainage system for the Ro-Ro ship deck. This system enables the crew on the Ro-Ro ship to more effectively clean dirt and sewage on the deck, improving cleaning efficiency. It effectively maintains the cleanliness of the vehicle deck 100 of the Ro-Ro ship and improves the operational efficiency of maritime transport operations involving both full vehicle transport and cargo transport, while reducing the time and effort costs associated with cleaning operations.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
