[0002] Electromagnetic interference (EMI) is a critical factor for equipment on electric bulk carriers, as these vessels house not only complex electric propulsion systems but also various electronic devices and communication and navigation systems whose proper operation is essential for the ship's safety and efficiency. EMI can cause equipment malfunctions and even system failures. For example, interference can affect the quality of radio communications, causing signal distortion, interference, or disconnection. Navigation equipment such as radar and electronic nautical charts may experience false alarms or malfunctions, affecting navigation safety. Various electronic devices on board may become unstable due to interference, reducing system reliability. In extreme cases, severe electromagnetic interference may cause critical systems to fail, increasing safety risks. These systems and communications all use cables at the hull, but traditional shielded cables are often laid together with power cables, which, due to the limited spacing between the hull and the cables, are prone to mutual interference. Therefore, this application provides an electromagnetic interference suppression device for electric bulk carriers. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an electromagnetic interference suppression device for electric bulk carriers, which solves the problem that traditional shielded cables and power transmission cables are arranged together, and mutual interference is easily caused due to the limited spacing between the ship hulls.

[0004] The present invention relates to an electromagnetic interference suppression device for electric bulk carriers, including bulk carriers used for loading cargo. The bulk carrier includes a hull, a loading area on the hull, and an equipment area located on one side of the hull. One or more partitions are provided on the inner side of the equipment area, and a cable groove is provided between every two partitions for organizing the cables connecting the equipment. The cable tray includes a tray body, on both sides of the inner wall of the tray body there are grooves at equal intervals, a shielding plate is installed on the inner side of the grooves, and a protrusion is provided below the shielding plate at the middle of the inner side of the tray body and on the top of the shielding plate for separating different types of cables.

[0005] As a further improvement of this utility model, a slot is provided on the top of the protrusion, and a positioning block is fitted into the slot. The positioning block is located at the bottom of the shielding plate.

[0006] As a further improvement of this utility model, a through hole is provided on one side of the protrusion, a connecting plate is installed at the through hole, and a flexible tube is connected through the connecting plate to change the position of the wire groove arrangement.

[0010] As a further improvement of this utility model, the partition includes a plate body, and heat-conducting plates are provided on both sides of the plate body, and the heat-conducting plates are in contact with the inner side of the hull.

[0011] As a further improvement of this utility model, a circulation pipe is provided on the inner side of the plate. The circulation pipe is bent and coiled at a preset angle, and its two ends extend through the plate to one side of the heat-conducting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model achieves effective cable separation through the combination of bumps, shielding plates, and positioning blocks, reducing the possibility of electromagnetic coupling and lowering electromagnetic interference. The design of bumps and shielding plates ensures physical isolation between different types of cables (such as power lines and signal lines), further improving electromagnetic compatibility. Furthermore, the combination of through holes, connecting plates, and flexible hoses enables flexible adjustment of the cable tray layout, making it easy to adapt to different equipment layouts and cable routing. The protrusions and grooves on both sides of the shielding plate allow for flexible adjustment of its position. Multiple shielding plates can be connected through positioning slots to form a unified cable management area. The ventilation holes on the shielding plate ensure airflow to the outside of the cables, aiding in heat dissipation and preventing moisture, thus extending the cable's lifespan. Utilizing the contact between the partition plate and the hull structure through the heat-conducting plate, along with the coordinated work of the internal circulation pipe and filling medium, efficient heat transfer and dissipation are achieved, reducing the temperature in the equipment area. By reducing electromagnetic interference and optimizing heat dissipation, the risk of equipment failure is reduced, improving the safety of ship operation and the reliability of equipment. The orderly cable arrangement and effective heat dissipation management also reduce safety hazards such as fires. Attached Figure Description

[0018] Please see Figure 1-8 Electromagnetic interference (EMI) is a very important consideration for equipment on the electric bulk carrier 1, because the ship not only has a complex electric propulsion system, but also various electronic devices and communication and navigation systems, the proper operation of which is crucial to the safety and efficiency of the vessel. EMI may cause equipment malfunctions or even system failures; For example, interference may affect the quality of radio communications, causing signal distortion, interference, or disconnection. Navigation equipment such as radar and electronic nautical charts may experience false alarms or malfunctions, affecting navigation safety. Various electronic devices on board may become unstable due to interference, reducing system reliability. In extreme cases, severe electromagnetic interference may cause critical systems to fail, increasing safety risks. These systems and communications all use cables at the hull 11. However, traditional shielded cables and power transmission cables are often laid together, and due to the limited spacing at the hull 11, mutual interference is likely to occur. Therefore, this application provides an electromagnetic interference suppression device for an electric bulk carrier 1, including the bulk carrier 1 used for loading cargo. The bulk carrier 1 includes a hull 11, a loading area 12 disposed on the hull 11, and an equipment area 13 located on one side of the hull 11; One or more partitions 14 are provided on the inner side of the equipment area 13, and a wire groove 15 is provided between every two partitions 14 for organizing the cables connecting the equipment. The cable tray 15 includes a tray body 151. The inner wall of the tray body 151 is provided with grooves 155 at equal intervals on both sides. A shielding plate 154 is installed on the inner side of the grooves 155. A protrusion 156 is provided below the shielding plate 154, in the middle of the inner side of the tray body 151, and on the top of the shielding plate 154, for separating different types of cables.

[0019] The bulk carrier 1 includes a hull 11, a loading area 12, and an equipment area 13. The equipment area 13 is located on one side of the hull 11 and has multiple partitions 14 inside. Each partition 14 has a cable tray 15 between it for organizing and protecting the cables connecting the various devices.

[0020] The cable tray 15 consists of a tray body 151, and the inner wall of the tray body 151 has equally spaced sliding grooves 155 on both sides. These sliding grooves 155 are used to install shielding plates 154, which can slide in the sliding grooves 155 to adjust their position or replace them.

[0021] A shielding plate 154 is installed within a groove 155, and has protrusions 156 on its lower and upper parts. These protrusions 156 are used to separate different types of cables, ensuring that they do not interfere with each other. For example, power lines and signal lines can be separated to prevent electromagnetic interference.

[0022] By setting protrusions 156 above and below the shielding plate 154, different cables can be placed in categories, maintaining an appropriate distance between cables and reducing electromagnetic coupling.

[0023] Within the equipment area 13, appropriate partitions 14 and cable trays 15 are installed according to the equipment layout and cable routing. Cables are placed into different sections of the cable trays 15 according to their type, and are isolated using shielding plates 154 and protrusions 156.

[0024] Because the cables are neatly organized within the cable tray 15 and isolated by the shielding plate 154, maintenance and repair work is more convenient. Specific cables can be easily located, reducing the risk of misoperation.

[0025] By using physical isolation and shielding measures, electromagnetic interference between different cables can be reduced, the electromagnetic compatibility of the equipment can be improved, and the stable operation of the equipment can be ensured.

[0026] By separating different types of cables and isolating them with shielding plate 154, electromagnetic interference is effectively reduced and the operational stability of the equipment is improved.

[0027] The cables are neatly arranged in the cable tray 15, making them easy to identify and manage, which greatly facilitates daily maintenance and repair work.

[0028] Reducing electromagnetic interference can lower equipment failure rates and improve the safety of ship operations, especially in critical systems involving navigation and communication.

[0029] Given the limited space in the hull 11, the reasonable arrangement of the cable trays 15 and shielding plates 154 not only suppresses electromagnetic interference but also makes full use of the limited space.

[0030] The top of the protrusion 156 is provided with a slot 159, and a positioning block 1511 is fitted into the slot 159. The positioning block 1511 is located at the bottom of the shielding plate 154.

[0031] A through hole 1510 is provided on one side of the protrusion 156. A connecting plate 152 is installed at the through hole 1510, and a flexible hose 153 is connected through the connecting plate 152 to change the position of the cable tray 15.

[0032] The top of the protrusion 156 has a slot 159, and the positioning block 1511 fits into the slot 159 and is installed at the bottom of the shielding plate 154. This design allows the shielding plate 154 to be firmly fixed on the protrusion 156, ensuring the orderly arrangement of cables in the cable tray 15.

[0033] A through hole 1510 is provided on one side of the protrusion 156, through which a connecting plate 152 is installed. A flexible hose 153 is connected to the connecting plate 152. This design allows the arrangement of the wire trough 15 to be changed through the flexible hose 153, increasing the flexibility of the device.

[0034] The flexible hose 153 can be used to guide the cable routing or as an additional protective layer to further reduce electromagnetic interference. In addition, the flexibility of the flexible hose 153 makes the arrangement of the cable tray 15 more flexible and can adapt to the complex internal structure of the hull 11.

[0035] During installation, first fix the protrusion 156 to the inner center of the groove 151 and the top of the shielding plate 154. Then, insert the positioning block 1511 into the slot 159 on the top of the protrusion 156 to fix the position of the shielding plate 154.

[0036] Next, the connecting plate 152 is installed through the through hole 1510 on the side of the protrusion 156, and the flexible hose 153 is connected to the connecting plate 152. The flexible hose 153 can guide the cable to different positions as needed, enabling flexible cable management.

[0037] Due to the design of the connecting plate 152 and the flexible hose 153, the arrangement of the cable tray 15 can be adjusted to adapt to different equipment layouts or changes in cable routing. This flexibility makes cable management more convenient when equipment is added or changed, reducing the complexity and cost of rewiring.

[0038] The combined use of bump 156 and shielding plate 154 effectively separates different types of cables, reducing the possibility of electromagnetic coupling.

[0039] The use of flexible hose 153 can provide additional shielding when necessary, further reducing electromagnetic interference.

[0040] The cooperation of the protrusion 156, the positioning block 1511 and the shielding plate 154 enables precise separation and fixation of the cables, keeping the cables neatly arranged and facilitating management and maintenance.

[0041] The combination of through hole 1510, connecting plate 152 and flexible hose 153 allows the arrangement of cable tray 15 to be flexibly adjusted to adapt to different installation requirements and space constraints.

[0042] The separation provided by the bump 156 and the shielding plate 154, along with the additional shielding provided by the flexible hose 153, significantly reduces electromagnetic interference between different cables and improves the electromagnetic compatibility of the equipment. The orderly cable arrangement and flexible cable tray 15 layout make it easier for maintenance personnel to identify and access specific cables, reducing maintenance time and service costs.

[0043] One or more ventilation holes 157 are provided at the plate body 141 of the shielding plate 154 to ensure air circulation on the outside of the cable.

[0044] Both sides of the shielding plate 154 are provided with protrusions 156 that are adapted to the slide groove 155 for positioning the shielding plate 154.

[0045] A positioning groove 158 is provided on the protrusion 156 located on the top of the shielding plate 154. The positioning groove 158 is used to cooperate with another shielding plate 154 for fixation.

[0046] The shielding plate 154 has one or more ventilation holes 157 on its body 141. These holes are designed to ensure airflow to the outside of the cable. The ventilation holes 157 not only help dissipate heat but also prevent the cable packaging from being damaged by excessive temperature or moisture. For example, in high-temperature environments, the ventilation holes 157 can effectively reduce the cable temperature and extend the cable's lifespan.

[0047] Both sides of the shielding plate 154 are provided with protrusions 156 that mate with the sliding grooves 155. These protrusions 156 are used to position the shielding plate 154. Through the cooperation of the protrusions 156 and the sliding grooves 155, the shielding plate 154 can slide freely in the sliding grooves 155 to adjust its position and adapt to different cable layout requirements. This design makes the installation of the shielding plate 154 more flexible and also improves its installation stability.

[0048] A positioning groove 158 is provided on the protrusion 156 on the top of the shielding plate 154. The positioning groove 158 is used to fix the shielding plate 154 in place. For example, when multiple shielding plates 154 are required for cable isolation, the positioning groove 158 can cooperate with the protrusion 156 of another shielding plate 154 to form a stable connection and ensure the cable isolation effect.

[0049] First, slide the shielding plate 154 into place using the protrusions 156 on both sides of the slide groove 155, ensuring that the shielding plate 154 is fixed in the slide groove 155 and fits tightly against the groove body 151.

[0050] During installation, the positioning groove 158 on the protrusion 156 on the top of the shielding plate 154 can engage with the protrusion 156 of another shielding plate 154 to form a continuous cable separation area.

[0051] The design of the vent 157 allows the cable to maintain good ventilation within the shielding plate 154, preventing damage to the cable from overheating or moisture.

[0052] Since the protrusions 156 on both sides of the shielding plate 154 are compatible with the slide groove 155, the shielding plate 154 can be easily adjusted in the slide groove 155 to adapt to different cable arrangement requirements. The design of the positioning groove 158 allows multiple shielding plates 154 to be seamlessly connected to form a unified cable management area, which facilitates subsequent maintenance and repair.

[0053] Through the separation of the shielding plate 154 and the fixation of the positioning slot 158, different types of cables (such as power lines and signal lines) can be effectively isolated, reducing the occurrence of electromagnetic interference.

[0054] The protrusions 156 on both sides of the shielding plate 154 are adapted to the slide grooves 155, making the installation and adjustment of the shielding plate 154 more convenient and adaptable to different cable layout requirements.

[0055] Multiple shielding plates 154, in cooperation with positioning slots 158, form a unified cable management area, which facilitates the orderly arrangement and management of cables.

[0056] The partition 14 includes a plate body 141, and heat-conducting plates 143 are provided on both sides of the plate body 141. The heat-conducting plates 143 are in contact with the inner side of the hull 11.

[0057] A circulation pipe 142 is provided on the inner side of the plate 141. The circulation pipe 142 is bent and coiled at a preset angle, and its two ends extend through the plate 141 to one side of the heat-conducting plate 143.

[0058] The inner side of the plate 141, located outside the circulation pipe 142, is filled with a filling medium 145 for uniform heat conduction.

[0059] The partition 14 consists of a plate 141 and a heat-conducting plate 143. Heat-conducting plates 143 are provided on both sides of the plate 141, and the heat-conducting plates 143 are in close contact with the inner side of the hull 11. This effectively transfers heat from the partition 14 to the structure of the hull 11, allowing for rapid heat dissipation through the metal material of the hull 11.

[0060] A circulation pipe 142 is provided on the inner side of the plate 141. The circulation pipe 142 is bent and coiled at a preset angle. Both ends of the circulation pipe 142 pass through the plate 141 and extend to one side of the heat-conducting plate 143. The circulation pipe 142 can be used to transport cooling medium (such as cooling water or cooling oil), and the heat on the plate 141 is removed by circulation, further enhancing the heat dissipation effect of the partition 14.

[0061] The inner side of the plate 141, located outside the circulation pipe 142, is filled with a filling medium 145. The filling medium 145 is usually a material with good thermal conductivity (such as thermal grease or thermal adhesive) to distribute heat evenly and ensure that heat can be efficiently transferred from the plate 141 to the circulation pipe 142 and the heat-conducting plate 143.

[0062] First, fix the partition 14 in the equipment area 13 of the hull 11 to ensure that the plate 141 is in close contact with the structure of the hull 11 so that heat can be transferred smoothly.

[0063] Install the circulation pipe 142, bend and coil it at a preset angle, and ensure that both ends of the circulation pipe 142 pass through the plate 141 and extend to one side of the heat conduction plate 143 so that the cooling medium can flow.

[0064] The outer side of the circulation pipe 142 is filled with a filling medium 145 with good thermal conductivity to ensure that the heat can be evenly distributed and quickly transferred to the hull structure 11 through the circulation pipe 142 and the heat conduction plate 143.

[0065] During operation, the heat from the baffle 14 is evenly distributed through the filling medium 145 and transferred to the circulation pipe 142 and the heat-conducting plate 143. The cooling medium flows in the circulation pipe 142, carrying away heat and further reducing the temperature of the baffle 14.

[0066] The contact between the heat-conducting plate 143 and the structure of the hull 11 ensures that heat can be quickly dissipated to the external environment through the metal material of the hull 11, thus enhancing the overall heat dissipation effect.

[0067] The partition 14, through close contact with the heat-conducting plate 143 and the structure of the hull 11, can quickly transfer heat to the hull 11 and dissipate it rapidly through the metal material of the hull 11. This significantly improves the heat dissipation efficiency of the partition 14 and reduces the temperature of the equipment area 13.

[0068] The use of filling medium 145 ensures that the heat inside the partition 14 can be evenly distributed, avoiding the problem of excessive local temperature. Through the coordinated work of filling medium 145, circulation pipe 142 and heat conduction plate 143, rapid and uniform heat transfer is achieved.

[0069] The efficient heat dissipation design reduces the temperature of the equipment area 13, minimizing the risk of equipment failure due to high temperatures and extending the equipment's lifespan. Especially under high-load operation, the effectiveness of heat dissipation directly impacts the reliability of the equipment.

[0070] The heat dissipation design of the bulkhead 14 integrates the heat conduction plate 143, the circulation pipe 142 and the filling medium 145, forming a compact and efficient heat dissipation system, reducing the need for additional heat dissipation equipment on the hull 11 and optimizing space utilization.

[0071] The pre-designed angled bending and coiling of the circulation pipe 142 allows it to adapt to different equipment layouts and space constraints. Meanwhile, the flexible selection of the cooling medium enables the heat dissipation system to operate efficiently under varying ambient temperatures.

[0072] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
