Utility Model Content

[0004] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art and to provide a marine diesel engine side control box. The marine diesel engine side control box can adjust the installation height of the control box through a bracket to be suitable for more diesel engines of different sizes, and the internal components of the control box are cooled by a cooling fan, so the heat dissipation efficiency is high.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A ship diesel engine side control box is used to control the ship diesel engine, comprising a control cabinet, a bracket and a cooling fan, wherein the bracket comprises a first connecting member, a second connecting member and a support leg, the first connecting member being mounted on the second connecting member by means of bolts; the support leg is provided with two positioning screw holes, and the bracket is mounted and fixed on the horizontal plane of the ship through the positioning screw holes of the support leg; a connecting plate is provided on the upper part of the bracket, the connecting plate is connected to the first connecting member through screw holes, the control cabinet is mounted on the bracket through the connecting plate, and the cooling fan is mounted on the back of the control cabinet.

[0007] Furthermore, the bracket includes a first bracket and a second bracket, a connecting rod is provided between the first bracket and the second bracket, the connecting rod connects the first bracket and the second bracket through bolts, and the first connecting member and the second connecting member are also connected together through the connecting rod.

[0008] The frame structure formed by the first and second brackets, along with the use of connecting rods, enhances the overall stability and rigidity of the control box. This design effectively disperses and withstands external forces from all directions, such as vibration and shaking during navigation, thereby protecting the internal electronic equipment from damage. The use of bolted connections makes bracket assembly and adjustment more flexible and simple. The distance and angle between the brackets can be adjusted to suit different installation environments while ensuring stable installation. This design is conducive to rapid positioning and adjustment of on-site installation, reducing installation time and cost. The design concept of connecting the first connecting piece and the second connecting piece through a connecting rod embodies the modular concept, which means that when maintaining or replacing parts, the damaged part can be replaced in a targeted manner without replacing the entire bracket system, reducing maintenance costs and improving the maintainability and upgrade potential of the system. Through the precisely designed bracket structure, the limited space inside the ship or on the deck can be effectively utilized to ensure that the control box is stable after installation and does not hinder the operation of other equipment or the passage of personnel, optimize the space layout, and improve the overall utilization efficiency. The stable bracket structure and reliable connection method can further improve the safety of the control box, prevent the equipment from falling off due to accidental collision or strong vibration, and ensure that the control box can still work stably in severe sea conditions or emergencies, thereby ensuring the safety of ship operation.

[0009] Furthermore, the connecting rod is a V-shaped sheet metal bending part, and two screw holes are provided at the head and tail sections of the connecting rod.

[0010] The design of the V-shaped sheet metal bending part increases the structural strength and bending resistance of the connecting rod, especially when subjected to lateral force and torsion. It performs better and can effectively prevent the control box from displacement or shaking during ship movement, maintaining the stability and safety of the overall structure. The V-shaped structure can distribute external forces more evenly in mechanics, reduce stress concentration points, and avoid damage to the connection parts due to excessive local force, thereby improving the durability and reliability of the connecting rod. The design of two screw holes at each end provides more installation flexibility, allowing the bracket to be fixed from different directions, facilitating rapid adjustment and precise alignment on site according to actual conditions, and also facilitating subsequent maintenance and parts replacement. Compared with traditional casting or forging processes, the sheet metal bending process is usually lower in cost and higher in production efficiency. In addition, the V-shaped design itself is relatively simple, reducing the use of materials and helping to control costs. V-shaped sheet metal parts usually have a smoother and more modern appearance, which meets the aesthetic and lightweight requirements of ship equipment and helps to enhance the overall internal quality and external image of the ship.

[0011] Furthermore, two connecting plates are provided on the upper portion of the bracket, and the two connecting plates are respectively connected to the first connecting member, the second connecting member and the control cabinet through bolts.

[0012] The addition of a connecting plate provides an additional support point for the control cabinet, especially when the control cabinet is heavy or subject to significant vibration. This design effectively distributes weight and vibration, enhancing the stability and load-bearing capacity of the entire installation, ensuring safe and stable operation of the control cabinet in all sea conditions. Directly connecting the connecting plate to the control cabinet simplifies installation procedures, making installation more straightforward and quicker. The screw connection facilitates on-site position and angle adjustment, ensuring precise and secure installation of the control cabinet. This design also facilitates future removal and reinstallation of the control cabinet for maintenance or upgrades. If the control cabinet or internal components need to be replaced, simply loosen the corresponding screw connections, eliminating the need for extensive disassembly of the entire support structure, reducing maintenance time and effort. The use of the connecting plate enhances system design flexibility, allowing for customized installation solutions based on different control cabinet models or specific installation requirements, tailored to meet diverse vessel designs. The additional fixing points enhance the stability of the control cabinet during vessel movement, reducing safety hazards such as loosening or falling equipment due to vibration or impact, further enhancing vessel safety.

[0013] Furthermore, the cooling fan is provided on the back of the control cabinet and is fixed to the control cabinet by bolts.

The display screen is provided on the upper part of the front of the control cabinet, the control buttons are provided on the lower part of the front of the control cabinet, and the cabinet door switch is provided on the right part of the front of the control cabinet.

[0014] A cooling fan is bolted directly onto the back of the control cabinet, ensuring stable operation and effectively exhausting hot air from the cabinet. This provides necessary cooling for the internal electronic components, preventing performance degradation or damage caused by overheating and improving equipment reliability and lifespan. A display screen, located on the upper front of the control cabinet, allows easy viewing and reading of diesel generator set operating data and status information, enabling operators to quickly understand system conditions and respond promptly. This layout promotes intuitive and efficient operation. Ergonomically positioned at the lower front, the control buttons allow operators to reach them directly while standing, enabling them to start, stop, and adjust operations without bending or searching, enhancing ease and comfort. The door switch is located on the right side of the front, independent of the display screen and control buttons, preventing accidental operation and facilitating quick opening and closing of the control cabinet door for internal inspection or maintenance. This design incorporates both safety and practicality. The overall layout is organized according to functional areas, creating a clean and organized layout that facilitates maintenance and upgrades. The separate zones for the display screen, control buttons, and door switch also facilitate future modular replacement or upgrades, enhancing system flexibility and maintainability.

[0015] The utility model has the following beneficial effects:

[0016] The bracket structure consisting of the first connecting member, the second connecting member and the supporting legs, as well as the design of multiple screw holes and positioning screw holes, can ensure that the control box is firmly installed on the horizontal surface of the ship. Even if the ship encounters bumps, shaking or encounters harsh sea conditions during navigation, it can remain stable, reducing the impact of vibration on the delicate electronic equipment in the control box and extending its service life. At the same time, the height of the control box can be adjusted by adjusting the position of the connecting rod on the connecting plate, which can meet the installation requirements of more diesel engine control boxes of different sizes.

[0017] The cooling fan installed on the back of the control cabinet directly forces air cooling on the internal heat source, effectively removing the heat generated by the electronic components in the control cabinet, and preventing equipment overheating, performance degradation, or even damage due to excessive temperature. This is crucial to improving the reliability of the entire diesel unit and extending its service life, especially during long-term continuous operation or high-temperature environments.
