Description

Technical Field

[0001] This utility model relates to the field of marine machinery, and in particular to a marine machinery with a heat dissipation structure. Background Technology

[0002] Marine engines are the core power system of a ship, mainly responsible for providing propulsion power and electrical energy, as well as various auxiliary functions required for the ship's navigation, operation and personnel life. They include key equipment such as main engines, generators, transmission devices, steering gear, pump systems, heat exchange equipment, as well as corresponding control, monitoring and maintenance systems, and are the core part to ensure the safe and efficient operation of the ship.

[0003] In existing technologies, heat dissipation of ship engines is mainly achieved through cooling systems, commonly including open and closed cooling systems. Open cooling systems directly use outboard water to cool the main and auxiliary engines, and then discharge it overboard. They have a simple structure but the water quality is poor and prone to corrosion. Closed cooling systems, on the other hand, use freshwater pumps to draw in freshwater to cool the main and auxiliary engines. The outboard water carries away excess heat from the freshwater through a freshwater cooler, indirectly cooling the diesel engine. They have good water quality and less scale buildup, and are widely used.

[0004] In existing technologies, ship engines are prone to heat accumulation under high loads. Relying solely on a single fan, the internal airflow direction is mostly fixed, making it impossible to flexibly adjust the airflow direction. Cooling air cannot be precisely applied to the heat-generating parts, thus failing to ensure stable engine operation. Therefore, a ship engine with a heat dissipation structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a marine engine with a heat dissipation structure, aiming to solve the problem that the airflow direction inside most marine engines is fixed in the prior art, making it impossible to flexibly adjust the airflow direction and making it difficult for cooling air to accurately act on the heat-generating parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a marine engine with a heat dissipation structure, comprising a hull, a protective box fixedly connected to the outer wall of the hull, a support block fixedly connected to the inner wall of the protective box, a motor I fixedly connected to the top of the support block, a rotating rod fixedly connected to the output shaft of the motor I, a helical gear set fixedly connected to the outer wall of the rotating rod, a fan fixedly connected to the top of the helical gear set, a support frame fixedly connected to the inner wall of the protective box, a motor II fixedly connected to the top of the support frame, a bidirectional threaded rod fixedly connected to the output shaft of the motor II, a threaded sleeve threadedly connected to the outer wall of the bidirectional threaded rod, a limit block fixedly connected to the outer wall of the threaded sleeve, a movable grid plate fixedly connected to the top of the limit block, a fixed grid plate slidably connected to the top of the movable grid plate, a blowing ring pipe fixedly connected to the top of the fixed grid plate, blowing holes fixedly connected to the outer wall of the blowing ring pipe, and a marine engine fixedly connected to the top of the fixed grid plate.

[0007] As a further description of the above technical solution: The outer wall of the rotating rod is rotatably connected to the inner wall of the housing, the outer wall of the rotating rod is rotatably connected to the inner wall of the protective box, the outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the protective box, and the outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the housing.

[0008] As a further description of the above technical solution: A limiting plate is fixedly connected to the inner wall of the housing, and the inner wall of the limiting plate is rotatably connected to the outer wall of the fan.

[0009] As a further description of the above technical solution: A filter screen is fixedly connected to the top of the fixed grid plate, and the outer wall of the filter screen is fixedly connected to the inner wall of the housing.

[0010] As a further description of the above technical solution: A limiting rod is fixedly connected to the inner wall of the housing, and the outer wall of the limiting rod is slidably connected to the inner wall of the limiting block. The outer wall of the fixed grid plate is fixedly connected to the inner wall of the housing.

[0011] As a further description of the above technical solution: The outer wall of the movable grid plate is slidably connected to the inner wall of the housing, and the outer wall of the movable grid plate is slidably connected to the inner wall of the protective box.

[0012] As a further description of the above technical solution: A support plate is fixedly connected to the inner wall of the protective box, and the top of the support plate is slidably connected to the bottom of the movable grid plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the heat dissipation structure can accurately dissipate heat when the temperature of the ship's engine is too high. The motor drives the helical gear set to drive the fan to draw in external air, and another motor drives the component to misalign the moving grid plate with the hole of the fixed grid plate, guiding the air into the blowing ring pipe. After being sprayed out from the blowing hole, the air flows along the groove of the outer wall of the engine, effectively reducing the temperature of the engine and ensuring its stable operation.

[0014] 2. In this utility model, when the ship's engine does not require dedicated cooling, the heat dissipation structure can use a motor to drive the components to make the moving grid plate and the fixed grid plate holes overlap, allowing air to circulate directly to cool other equipment. This not only avoids local high temperature damage to the internal structure of the hull and the engine, but also ensures the stable operation efficiency of the engine and improves the safety of equipment operation.

[0018] Reference Figures 1-3The present invention provides an embodiment of a marine engine with a heat dissipation structure, comprising a hull 1, which serves as the overall mounting base for the engine, supporting various components and forming a protective space. A protective box 2 is fixedly connected to the outer wall of the hull 1, protecting internal components such as a motor 4 and a support frame 9 from external interference. A support block 3 is fixedly connected to the inner wall of the protective box 2, supporting and fixing the motor 4 to ensure its stability during operation. The top of the support block 3 is fixedly connected to the motor 4, which provides power for the rotation of a rotating rod 5. The output shaft of the motor 4 is fixedly connected to the rotating rod 5. Rod 5 transmits power to motor 4, driving helical gear set 6 to rotate. Helical gear set 6 is fixedly connected to the outer wall of rod 5. Helical gear set 6 changes the direction of power transmission, converting the horizontal rotation of rod 5 into the vertical rotation of fan 7. Fan 7 is fixedly connected to the top of helical gear set 6. The rotation of fan 7 generates airflow, providing a basic cooling air source for marine engine 20. Support frame 9 is fixedly connected to the inner wall of protective box 2. Support frame 9 supports and fixes motor 10, ensuring the stability of motor 10 during operation. Motor 10 is fixedly connected to the top of support frame 9. Motor 10 provides power for the rotation of bidirectional threaded rod 11. The output shaft of motor 210 is fixedly connected to a bidirectional threaded rod 11. The bidirectional threaded rod 11 rotates to drive the outer threaded sleeve 12 to move relative to or towards each other. The outer wall of the bidirectional threaded rod 11 is threadedly connected to the threaded sleeve 12, which drives the limit block 13 and the movable grid plate 15 to move. The outer wall of the threaded sleeve 12 is fixedly connected to the limit block 13, which connects the threaded sleeve 12 and the movable grid plate 15 to achieve power transmission. The top of the limit block 13 is fixedly connected to the movable grid plate 15. The movable grid plate 15, through sliding cooperation with the fixed grid plate 16, adjusts the opening and closing degree of the grid plate to control the air intake. The top of the movable grid plate 15... A fixed grid plate 16 is slidably connected, providing a sliding track for the movable grid plate 15. It is also connected to the filter screen plate 17 and the air blowing ring pipe 18. The air blowing ring pipe 18 is fixedly connected to the top of the fixed grid plate 16. The air blowing ring pipe 18 is used to evenly deliver airflow to the area around the ship's engine 20. Air blowing holes 19 are fixedly connected to the outer wall of the air blowing ring pipe 18. The air blowing holes 19 are used to direct the airflow in the air blowing ring pipe 18 toward the ship's engine 20 to enhance the heat dissipation effect. The ship's engine 20 is fixedly connected to the top of the fixed grid plate 16. The ship's engine 20 is the core component of the ship's power system. The heat generated during operation needs to be cooled by the heat dissipation structure.

[0019] Reference Figures 3-5The outer wall of the rotating rod 5 is rotatably connected to the inner wall of the housing 1, and the outer wall of the rotating rod 5 is rotatably connected to the inner wall of the protective box 2. The outer wall of the bidirectional threaded rod 11 is rotatably connected to the inner wall of the protective box 2, and the outer wall of the bidirectional threaded rod 11 is rotatably connected to the inner wall of the housing 1. A limiting plate 8 is fixedly connected to the inner wall of the housing 1. The limiting plate 8 is used to limit the position of the fan 7 and prevent the fan 7 from deviating when rotating. The inner wall of the limiting plate 8 is rotatably connected to the outer wall of the fan 7. A filter screen 17 is fixedly connected to the top of the fixed grid plate 16. The filter screen 17 is used to filter the airflow entering the housing 1 and prevent impurities from adhering to the ship's engine 20. The outer wall of the filter screen 17 is fixedly connected to the inner wall of the housing 1. The outer wall of the filter screen 17 is fixedly connected to the inner wall of the housing 1.

[0020] Reference Figures 4-6 A limiting rod 14 is fixedly connected to the inner wall of the housing 1. The limiting rod 14 limits the sliding of the limiting block 13. The outer wall of the limiting rod 14 is slidably connected to the inner wall of the limiting block 13. The outer wall of the fixed grid plate 16 is fixedly connected to the inner wall of the housing 1. The outer wall of the movable grid plate 15 is slidably connected to the inner wall of the housing 1. The outer wall of the movable grid plate 15 is slidably connected to the inner wall of the protective box 2. A support plate 21 is fixedly connected to the inner wall of the protective box 2. The support plate 21 is used to support the movable grid plate 15 and reduce the friction when the movable grid plate 15 slides. The top of the support plate 21 is slidably connected to the bottom of the movable grid plate 15.

[0021] Working principle: When the temperature of the ship's engine 20 is too high, the first motor 4 is started. The output shaft of the first motor 4 drives the rotating rod 5 to rotate, which in turn drives the helical gear set 6, which consists of two helical gears, to move synchronously. One helical gear is fixedly connected to the rotating rod 5, and the other helical gear is fixedly connected to the fan 7. The rotation of the rotating rod 5 causes the two helical gears to move together, so that the fan 7 starts to rotate and external air enters the interior of the housing 1 through the filter screen at the bottom of the housing 1. Then, the second motor 10 is started. The output shaft of the second motor 10 drives the bidirectional threaded rod. When 11 rotates, the limiting block 13 moves on the bidirectional threaded rod 11 through the threaded sleeve 12, causing the two limiting blocks 13 to move away from each other, thereby causing the moving grid plate 15 to translate, so that the hole opened on the moving grid plate 15 is misaligned with the hole opened on the fixed grid plate 16, ensuring that the air entering from the bottom of the housing 1 can only enter the interior of the blowing ring pipe 18 through the hole at the bottom of the blowing ring pipe 18, and then be ejected from the blowing hole 19 opened on the blowing ring pipe 18. The outer wall of the ship engine 20 has a groove, so that the air blown by the blowing hole 19 can dissipate heat from the ship engine 20 along the groove.

[0022] When the temperature of the ship's engine 20 drops and no special cooling is needed, the motor 2 10 rotates again, and the output shaft of the motor 2 10 drives the bidirectional threaded rod 11 to rotate again. This causes the movable grid plate 15 to move in the same direction through the limit block 13, so that the movable grid plate 15 coincides with the hole on the fixed grid plate 16. This allows the air entering from the bottom of the shell 1 to circulate directly through the grid plate, thereby cooling other equipment. This not only avoids damage to the internal structure of the shell 1 and the ship's engine 20 caused by excessively high local temperatures, but also ensures the stable operation and efficiency of the engine.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
