Description

Technical Field

[0001] This invention relates to a ship ventilation system, and more specifically to a customized ventilation system and method for roll-on / roll-off ships. Background Technology

[0002] During a roll-on / roll-off (Ro-Ro) ship voyage, a large number of cars are stored in the cabins. As the cars enter the cabins, they release a large amount of exhaust fumes. In addition, the condition of different fuel-powered cars varies, and those in poor condition may have some degree of oil leakage. All of these factors combined result in a high concentration of pollutants inside the cabins. In particular, when the concentration of gasoline in the air is too high, a fire could spread rapidly, posing a great safety hazard.

[0003] However, most current methods for reducing pollutant concentrations in the cabins of roll-on / roll-off ships involve supplying air to one end of the cabin. This method results in a relatively turbulent overall airflow field inside the cabin, which cannot effectively remove pollutants from the cabin.

[0004] Current technologies generally rely on global ventilation to improve cabin air quality. However, this method requires a very large air volume, and the large open spaces of ship cabins often create dead zones, resulting in wasted airflow. Therefore, a personalized ventilation solution is urgently needed. This solution primarily utilizes a combination of targeted localized ventilation and exhaust to control air quality within specific areas of the ship. The advantage of this approach is that it eliminates the need for global ventilation; targeted ventilation and exhaust can effectively improve air quality in areas with high pollutant concentrations. Furthermore, the inclusion of a central control module allows for real-time adjustments to the ventilation and exhaust scheme based on changes in internal pollutant concentrations. Summary of the Invention

[0005] The purpose of this invention is to provide a personalized ventilation system and method for roll-on / roll-off (Ro-Ro) ships, which effectively removes pollutants from the cabin air by utilizing bottom-mounted air supply and personalized exhaust. This system can identify areas with high pollutant concentrations and then focus on removing pollutants from those areas.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A personalized ventilation system for roll-on / roll-off ships includes a bottom air supply system and a personalized exhaust system. The bottom air supply system is installed on the lower deck, and under the joint action of a pollutant concentration monitoring module and a central control module, it activates the corresponding area's fan module for ventilation to fully disturb the bottom pollutants. The personalized exhaust system is installed at the bottom of the upper deck, and the central control module receives information from the pollutant concentration monitoring module in the bottom air supply system and sends instructions to the corresponding top-floor air duct layout module and exhaust module, thereby quickly exhausting the pollutants in the corresponding area to the outside of the cabin.

[0007] Furthermore, the bottom air supply system consists of a fan module, a bottom air duct module, a bottom air duct arrangement module, a pollutant concentration monitoring module, and a fixing module. The bottom air supply system fully extends the bottom air duct module on the lower deck of the cabin through the air duct arrangement module. After operation, the bottom air duct module is compressed by the bottom air duct arrangement module to reduce the storage volume.

[0008] Furthermore, the fan modules are arranged at both ends of the cargo hold inside the roll-on / roll-off ship to supply sufficient air into the cargo hold.

[0009] Furthermore, the bottom air duct module is used to redistribute the air supplied to the cargo hold area by the fan module, thereby delivering fresh air to various parts of the cabin; each bottom air duct module consists of multiple air duct modules, which are nested together in a certain order.

[0010] Furthermore, the bottom air duct arrangement module is equipped with a positioning device on its top to monitor its position relative to the fixed module and prevent yaw. The head is equipped with an electromagnet for connecting to the fixed module, and the tail is connected to the bottom air duct module for stretching and compressing the bottom air duct module, so that the air duct module can cover the entire cabin floor, thereby allowing for more comprehensive air delivery into the cabin.

[0011] Furthermore, the pollutant concentration monitoring module is arranged on each air duct module. When the bottom air duct module covers the cabin floor, the pollutant concentration monitoring module is also evenly arranged on the cabin floor. The pollutant concentration monitoring module inputs the signal to the central control module. The central control module controls the top air duct arrangement module to lower the corresponding exhaust air duct and start the corresponding exhaust module to draw air containing high concentrations of pollutants into the top air duct module.

[0012] Furthermore, the fixing modules are connected to the deck by welding, with each fan outlet corresponding to a fixing module, and the distance between each fixing module and the fan is equal to the total length of the corresponding bottom duct module.

[0013] Furthermore, the personalized ventilation system consists of a top-level air duct module, a top-level air duct layout module, a central control module, an exhaust module, and a single-direction ventilation module. The top-level air duct module is installed on the top panel of the cabin. Pollutants enter the sub-air ducts through the exhaust air ducts and finally converge into the main air ducts and are discharged into the external environment.

[0014] Furthermore, the single-direction ventilation module is installed inside the top-level air duct module to ensure that air can only be collected from the sub-air ducts of the top-level air duct module to the main air duct, and cannot flow in the opposite direction.

[0015] A personalized ventilation method for ro-ro ships, employing a personalized ventilation system for ro-ro ships, comprising the following steps:

[0016] Step 1: After the cars in the roll-on / roll-off ship cabin are loaded, the bottom air duct layout module is activated to unfold the multi-stage air duct modules of the bottom air duct module in sequence. At the same time, the front end of the bottom air duct layout module is energized to generate magnetic force and connect with the fixing module to ensure the stability of the bottom air duct module.

[0017] Step 2: The pollutant concentration monitoring module is activated, uploading the pollutant concentration of each area to the central control module. At the same time, the central control module controls the motor in the corresponding top-level air duct layout module to start. The motor uses pulleys to loosen the steel wire, causing the support rod to move downward, and at the same time, the exhaust module of the corresponding area is activated to start working.

[0018] Step 3: The central control module activates the corresponding fan module according to the distribution of pollutants, and introduces fresh air into the ship's cabin. The fresh air disturbs the pollutants, and the exhaust module draws the pollutants into the sub-duct through the exhaust duct, and finally exhausts them to the outside of the cabin through the main duct. The one-way ventilation module in the top duct module is used to ensure that air containing high concentrations of pollutants in areas where the exhaust module is not activated will not be discharged back into the cabin.

[0019] Step 4: When the roll-on / roll-off ship is about to reach its destination, the top-level air duct layout module and the bottom-level air duct layout module will retract the exhaust air duct in the top-level air duct module and the bottom air duct module respectively to make room for the cars to disembark.

[0020] The beneficial effects of this invention are:

[0021] 1. Both the top-level air duct arrangement module and the bottom air duct arrangement module in this invention are retractable. They only occupy a large space when working, and can be compressed into a smaller volume during non-working periods to save space.

[0022] 2. In this invention, a combination of a bottom air supply system and a top exhaust system is used. The bottom exhaust system fully disturbs the pollutants at the bottom, and then the top exhaust system extracts them to the outside of the cabin.

[0023] 3. The central control system in this invention can ensure that air from areas with high pollutant concentrations can be preferentially exhausted outside the cabin.

[0024] 4. The air supply and exhaust in this invention are customized according to the actual situation, which greatly reduces the workload of the equipment compared to air supply throughout the entire space. Attached Figure Description

Detailed Implementation

[0032] The preferred embodiments of the present invention will now be described in detail so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0033] like Figures 1 to 6As shown in the figure, the personalized ventilation system for a roll-on / roll-off ship provided by this embodiment of the invention mainly consists of two parts: the first part is a bottom air supply system located on the lower deck, and the second part is a personalized exhaust system located at the bottom of the upper deck. The bottom air supply system mainly consists of a fan module 111, a bottom air duct module, a bottom air duct arrangement module 131, a pollutant concentration monitoring module 141, and a fixing module 151; the personalized exhaust system mainly consists of a top air duct module, a top air duct arrangement module, a central control module 231, an exhaust module 241, and a single-direction ventilation module 251. The bottom air duct module is composed of multi-stage air duct modules; the top air duct arrangement module consists of pulleys 211, support rods 212, a motor 213, and steel wires 214; the top air duct module consists of a main air duct 221, sub-air ducts 222, and an exhaust air duct 223.

[0034] The bottom air duct arrangement module 131 is similar to an electric cart, see Figure 2 The top is equipped with a positioning device to monitor its position relative to the fixed module 151 and prevent it from veering off course. The head is equipped with an electromagnet for connecting to the fixed module 151. The tail is connected to the bottom air duct module, which mainly stretches and compresses the bottom air duct module so that the air duct module 111 can cover the entire cabin floor, thereby allowing more comprehensive airflow into the cabin.

[0035] like Figure 4 As shown in Figures 5 and 6, the top-level air duct module is installed on the top panel of the cabin. Pollutants enter the sub-air duct 22 through the exhaust air duct 223 and finally converge into the main air duct 221 and are discharged into the external environment.

[0036] The fan module 111 is mainly located at both ends of the cargo hold inside the roll-on / roll-off ship to supply sufficient air into the cargo hold. The bottom air duct module is used to redistribute the air supplied to the cargo hold area by the fan module 111, thereby delivering fresh air to various parts of the hold. Each bottom air duct module consists of multiple air duct modules, with the primary air duct module 121, secondary air duct module 122, tertiary air duct module 123, and quaternary air duct module 124 nested together in a specific order.

[0037] Pollutant concentration monitoring modules 141 are installed on each air duct module, see Figure 3 When the bottom air duct module covers the entire cabin floor, the pollutant concentration monitoring module 141 is also evenly distributed on the cabin floor. The pollutant concentration monitoring module 141 sends a signal to the central control module 231, which then controls the top air duct layout module to lower the corresponding exhaust duct 223 and activate the corresponding exhaust module 241 to draw air containing high concentrations of pollutants into the top air duct module.

[0038] The fixed module 151 is welded to the deck. Each fan outlet corresponds to one fixed module 151, and the distance between each fixed module 151 and the fan 213 is equal to the total length of the corresponding bottom air duct module. For each row of cars, there will be two sets of bottom air supply systems.

[0039] The single-direction ventilation module 251 is installed inside the top-level air duct module to ensure that air can only be collected from the sub-air duct 222 of the top-level air duct module to the main air duct 221, and cannot flow in the opposite direction.

[0040] The present invention provides a personalized ventilation method for ro-ro ships, employing a personalized ventilation system for ro-ro ships, comprising the following steps:

[0041] Step 1: After the car is loaded into the roll-on / roll-off ship cabin, the bottom air duct layout module 131 is activated to sequentially unfold the fourth-level air duct module 141, the third-level air duct module 131, the second-level air duct module 121, and the first-level air duct module 111. At the same time, the front end of the bottom air duct layout module 131 is energized to generate magnetic force and connect with the fixing module 151 to ensure the stability of the bottom air duct module.

[0042] Step 2: The pollutant concentration monitoring module 141 is activated, uploading the pollutant concentration of each area to the central control module 231. At the same time, the central control module 231 controls the motor 213 in the corresponding top-level air duct layout module to start. The motor 213 uses the pulley 211 to loosen the steel wire 214, causing the support rod 212 to move downward, and at the same time, the exhaust module 241 of the corresponding area is activated to start working.

[0043] Step 3: The central control module 231 activates the corresponding fan module 211 according to the distribution of pollutants, and introduces fresh air into the cabin. The fresh air disturbs the pollutants. Finally, the exhaust module 241 draws the pollutants into the sub-duct 222 through the exhaust duct 223, and finally exhausts them to the outside of the cabin through the main duct 221. The one-way ventilation module 251 in the top duct module is used to ensure that the air containing high concentrations of pollutants in the area where the exhaust module is not activated will not be discharged back into the cabin.

[0044] Step 4: When the roll-on / roll-off ship is about to reach its destination, the top-level air duct layout module and the bottom-level air duct layout module will retract the exhaust air duct in the top-level air duct module and the bottom air duct module respectively to make room for the cars to disembark.

Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
