Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator technology, and in particular to a marine generator set. Background Technology
[0002] Marine generators, as the heart of a ship's electrical system, play a crucial role in converting other forms of energy into electrical energy, providing power support for the ship's navigation, living conditions, and operations. Their working principle is based on electromagnetic induction. Typically, a prime mover (such as a diesel engine or steam turbine) drives the generator rotor to rotate, causing the rotor's magnetic field to cut magnetic lines of force with the stator windings, thereby generating an induced electromotive force in the stator windings and outputting electrical energy. Existing marine generator sets usually consist of a diesel engine and a generator. The diesel engine provides power to the generator to achieve electrical energy output. During prolonged operation, the generator generates a large amount of heat. Heat sinks are usually installed on the generator surface, but over time, dust accumulates on the surface of the heat sinks, affecting airflow and reducing heat dissipation efficiency. Furthermore, at sea, the air contains salt, moisture, and various impurities, which can easily enter the generator set, negatively impacting heat dissipation and potentially corroding components, reducing its reliability and stability. Therefore, this invention proposes a marine generator set. Utility Model Content
[0003] The purpose of this invention is to address the problems in the background technology where, after long-term use, heat sinks accumulate a large amount of dust on their surface, affecting airflow and reducing heat dissipation efficiency. Furthermore, due to sea travel, the air contains salt, moisture, and various impurities that can easily enter the generator set, negatively impacting its heat dissipation and potentially corroding its components, thus reducing its reliability and stability. Therefore, this invention proposes a marine generator set.
[0004] The technical solution of this utility model is as follows: a marine generator set, comprising: a base, a fixing frame fixedly mounted on the upper surface of the base, a diesel engine mounted on the fixing frame; a generator mounted on one side of the diesel engine, a coupling connected to one end of the generator, and the coupling connected to the diesel engine at one end; a first gear fixedly sleeved on one end of the generator, and a heat dissipation component for heat dissipation sleeved on the outer wall of the generator.
[0005] Optionally, the heat dissipation assembly includes a housing fixedly sleeved on the outer wall of the generator, a plurality of fixed cylinders fixedly through the housing, an air inlet filter plate and an air outlet filter plate fixedly installed on the outer wall of the fixed cylinder, a fan blade rotatably installed on the fixed cylinder, one end of the fan blade penetrating the fixed cylinder and extending to be connected to a second gear, the second gear meshing with the first gear.
[0006] Optionally, the generator is provided with heat sinks fixedly on its outer wall.
[0007] Optionally, a sealing cap is provided at one end of the housing, and a filter cylinder is threadedly connected to one end of the sealing cap.
[0008] Optionally, the intake filter plate is located on the outside of the housing, and the exhaust filter plate is located on the inside of the housing.
[0009] Optionally, a filter element is provided inside the filter cartridge.
[0010] Optionally, a first fixing block is fixedly provided on the outer wall of the housing, and a second fixing block is fixedly provided on the outer wall of the sealing cover, with a fixing bolt provided between the first fixing block and the second fixing block.
[0011] In summary, this application includes at least one of the following beneficial technical effects:
[0012] This invention, through the structure of the first gear, the second gear, and the fan blades, enables the automatic drive of the fan blades to rotate during generator operation. The rotation of the fan blades generates airflow, which accelerates the flow of air around the heat sink, greatly improving the heat dissipation efficiency and effectively avoiding the problem of performance degradation caused by the accumulation of heat generated during long-term generator operation.
[0013] Furthermore, this utility model achieves multiple filtrations of the air entering the generator set through the structure of the air intake filter plate, air outlet filter plate, filter element, and filter cylinder. This prevents salt, moisture, and impurities in the marine air from entering the generator, reducing their corrosion of generator components, ensuring the generator's heat dissipation effect, effectively improving the reliability and stability of the generator set, and extending its service life.

[0026] Example
[0027] like Figure 1 and Figure 2As shown, the marine generator set proposed by this utility model includes: a base 1, a fixing frame 2 is fixedly installed on the upper surface of the base 1, and the base 1 and the fixing frame 2 are integrally formed to increase their support strength. A diesel engine 3 is installed on the fixing frame 2, which can provide power output for the generator 4.
[0028] Furthermore, a generator 4 is installed on one side of the diesel engine 3, which can convert the power provided by the diesel engine 3 into electricity. A heat sink 8 is fixedly installed on the outer wall of the generator 4, which can quickly conduct heat out of the generator 4 to avoid damage due to overheating. A coupling 5 is connected to one end of the generator 4, and one end of the coupling 5 is connected to the diesel engine 3, which can stably connect the diesel engine 3 and the generator 4. A first gear 6 is fixedly sleeved on one end of the generator 4, which can drive the generator 4 to move the first gear 6 stably.
[0029] like Figure 2 and Figure 3 As shown, a heat dissipation assembly 7 for heat dissipation is fitted onto the outer wall of the generator 4. The heat dissipation assembly 7 includes a housing 71 fixedly fitted onto the outer wall of the generator 4. A first fixing block 12 is fixedly provided on the outer wall of the housing 71, and multiple first fixing blocks 12 are provided. Multiple fixing cylinders 72 are fixedly and through the housing 71, and the fixing cylinders 72 are arranged in a ring array. An air inlet filter plate 73 and an air outlet filter plate 74 are fixedly provided on the outer wall of the fixing cylinder 72. The air inlet filter plate 73 is located on the outside of the housing 71, and the air outlet filter plate 74 is located on the inside of the housing 71. They are used to dissipate the heat from the heat sink 8 on the outer wall of the generator 4. The fixing cylinder 72 is equipped with a fan blade 75 for rotation. One end of the fan blade 75 passes through the fixing cylinder 72 and extends to be connected to a second gear 76. The second gear 76 meshes with the first gear 6, so that the first gear 6 drives the fan blade 75 to rotate inside the fixing cylinder 72 through the second gear 76, thereby allowing the heat from the heat sink 8 to be quickly discharged through the flowing air, improving the heat dissipation efficiency.
[0030] Furthermore, a sealing cover 9 is provided at one end of the housing 71. A second fixing block 13 is fixedly provided on the outer wall of the sealing cover 9, and the second fixing block 13 corresponds to the first fixing block 12. A fixing bolt 14 is provided between the first fixing block 12 and the second fixing block 13, which can seal the sealing cover 9 to the housing 71 and facilitate disassembly and assembly. A filter cartridge 10 is threadedly connected to one end of the sealing cover 9. The threaded connection facilitates the removal and replacement of the filter cartridge 10 and the filter element 11. The filter cartridge 10 allows filtered air to enter the interior of the housing 71. The filter element 11 is provided inside the filter cartridge 10. The filter element 11 is an activated carbon filter element. Its loose and porous structure gives it a strong adsorption capacity. In addition to adsorbing moisture, it can also adsorb odors and some pollutants in the air, preventing moisture from entering the interior of the housing 71 and improving the service life of the generator 4.
[0031] In this embodiment, when the marine generator set is working, the diesel engine 3 starts running and drives the generator 4 to run synchronously through the coupling 5. At this time, the first gear 6, which is fixedly sleeved on one end of the generator 4, rotates accordingly. Since the first gear 6 is meshed with the second gear 76 at the end of the fan blade 75 in the heat dissipation assembly 7, the rotation of the first gear 6 will drive the second gear 76, thereby driving the fan blade 75 to rotate at high speed in the fixed cylinder 72.
[0032] The rotation of the fan blade 75 drives the airflow inside the housing 71. The airflow passes through the filter cylinder 10 to filter larger particles in the air, and the filter element 11 filters out salt, moisture and other fine impurities in the air before entering the interior of the housing 71. The airflow flows between the heat sink 8, carrying away heat. The heat enters the interior of the fixed cylinder 72 through the intake filter plate 73 and is discharged from the exhaust filter plate 74, thereby accelerating the airflow speed inside the housing 71, reducing its corrosion on the generator 4 components, ensuring the heat dissipation effect of the generator 4, improving the reliability and stability of the generator set, and extending its service life.
[0033] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
