Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation structure of diesel generator sets, and in particular to a high-efficiency heat dissipation containerized diesel generator set. Background Technology

[0002] In the modern industrial and power supply sectors, containerized diesel generator sets, as portable and high-efficiency power supply devices, are widely used in various temporary or long-term power supply needs, such as construction sites, mines, and remote areas. However, during long-term, high-load operation of containerized diesel generator sets, heat dissipation has always been a key factor affecting their performance and stable operation.

[0003] In practical applications, the focus is often solely on increasing the heat dissipation area or raising the fan speed, while neglecting airflow guidance and the cleaning and maintenance of heat dissipation components. Consequently, uneven heat dissipation, obstructed airflow, and dust accumulation frequently occur, severely impacting the generator set's heat dissipation performance and operational stability. These problems are particularly pronounced in complex environments such as high temperatures, dust, and humidity, not only reducing generator set performance but also potentially posing safety hazards, necessitating urgent improvements. Furthermore, these issues hinder precise dosage control for two types of drugs and impede improvements in the efficiency and quality of drug preparation and mixing.

[0004] Therefore, to address the aforementioned problems of inconvenience in improving gas flow efficiency and achieving efficient and reliable ventilation and heat dissipation, a high-efficiency heat dissipation containerized diesel generator set can be designed. During operation, multiple heat dissipation components are first activated to rotate, generating a powerful airflow for comprehensive ventilation and heat dissipation inside the container. Simultaneously, a translation component is activated, driving the heat dissipation components to rotate within a range via a transmission component, allowing for flexible adjustment of the airflow direction. Furthermore, as the translation component moves, the guide slide slides on the guide rod, driving the rotation of the rotating gears on both sides onto the fixed toothed plates. This rotation, in turn, drives the cleaning brushes on both sides to rotate via the rotating shafts on both sides. These cleaning brushes are tightly fitted onto the fixed ventilation... The sides of the air deflector effectively remove dust and impurities adhering to the ventilation plate, significantly improving airflow efficiency and further enhancing ventilation and heat dissipation capabilities. Additionally, the cleaned dust and impurities fall into the arc-shaped ash discharge trough below the fixed ventilation plate. At this point, the translation component drives the ash removal component to move parallel above the arc-shaped ash discharge trough, activating the ash removal component to generate airflow that smoothly discharges the dust in the arc-shaped ash discharge trough through the guide groove on the lower side to the outside of the heat dissipation box. In summary, this utility model, through its cleverly designed airflow adjustment mechanism and dust removal mechanism, not only expands the airflow guidance range but also significantly improves airflow efficiency, thereby achieving a more efficient and reliable ventilation and heat dissipation effect, ensuring the stable operation of the diesel generator set's heat dissipation structure in complex environments. Utility Model Content

[0005] To address the common problem of diesel generator set cooling structures focusing solely on increasing heat dissipation area or fan speed while neglecting airflow guidance and the cleaning and maintenance of cooling components, uneven heat dissipation, obstructed airflow, and dust accumulation frequently occur in practical applications, severely impacting the generator set's cooling performance and operational stability. These problems are particularly pronounced in complex environments such as high temperatures, dust, and humidity, not only reducing generator set performance but also potentially posing safety hazards, necessitating urgent improvements. Furthermore, these improvements hinder precise dosage control for two types of drugs and impede improvements in the efficiency and quality of drug preparation and mixing.

A heat dissipation box is installed inside one side of the container body, a translation component is installed inside the heat dissipation box, a transmission component is installed on one side of the translation component, a heat dissipation component is installed inside one side of the heat dissipation box, and a fixed ventilation plate is installed on the other side of the heat dissipation box. Two sets of guide grooves are provided on both the upper and lower sides of the fixed ventilation plate. The guide chute is equipped with a guide slide rod inside, and a guide slide seat is provided on the side wall of the guide slide rod. The guide slide seat is slidably connected to the guide slide rod. A translation link is provided on the other side of the translation component.

[0007] Preferably, during the operation of the diesel generator set's cooling structure, multiple cooling components are first activated to rotate, generating a powerful airflow for comprehensive ventilation and cooling of the container's interior. Simultaneously, the translation component, via a transmission component, drives the cooling components to rotate within a range, allowing for flexible adjustment of the airflow direction. Furthermore, as the translation component moves, the guide slide slides on the guide rod, causing the rotating gears on both sides to rotate on the fixed toothed plates. This rotation, in turn, drives the cleaning brushes on both sides to rotate via the rotating shafts. These cleaning brushes fit tightly against both sides of the fixed ventilation plate, effectively removing dust and impurities adhering to the ventilation plate, significantly improving cooling performance. This invention improves gas flow efficiency, further enhancing ventilation and heat dissipation capabilities. Additionally, the cleaned dust and impurities fall into the arc-shaped ash discharge trough below the fixed ventilation plate. At this point, the translation component drives the dust removal component to move parallel above the arc-shaped ash discharge trough. Activating the dust removal component generates airflow, smoothly discharging the dust from the arc-shaped ash discharge trough through the lower guide groove to the outside of the heat dissipation box. In summary, this invention, through its cleverly designed airflow adjustment mechanism and dust removal mechanism, not only expands the airflow guidance range but also significantly improves gas flow efficiency, thereby achieving a more efficient and reliable ventilation and heat dissipation effect, ensuring the stable operation of the diesel generator set's heat dissipation structure in complex environments.

[0009] Preferably, the translation assembly also includes a connecting rod and a translation slider. The translation slider is provided on the side wall of the translation screw and is threadedly connected to the translation screw. A connecting rod is provided on one side of the translation slider and the other end of the connecting rod is fixedly connected to the other side of the translation slider.

[0014] The beneficial effects of this utility model are:

[0015] During operation, the diesel generator set's cooling structure first activates multiple cooling components to rotate, generating a powerful airflow for comprehensive ventilation and cooling of the container's interior. Simultaneously, a translation component, via a transmission assembly, drives the cooling components to rotate within a range, allowing for flexible airflow adjustment. Furthermore, as the translation component moves, guide slides on guide rods, which in turn rotates the rotating gears on both sides of the fixed gear plates. This rotation, in turn, drives the cleaning brushes on both sides via rotating shafts. These brushes fit snugly against the sides of the fixed ventilation plates, effectively removing dust and impurities adhering to the ventilation plates, significantly improving cooling performance. This design improves gas flow efficiency and enhances ventilation and heat dissipation capabilities. Furthermore, the cleaned dust and impurities fall into the arc-shaped ash discharge trough below the fixed ventilation plate. At this point, the translation component moves the ash removal component parallel to the arc-shaped ash discharge trough, activating the ash removal component to generate airflow that smoothly discharges the dust from the arc-shaped ash discharge trough through the lower guide groove to the outside of the heat dissipation box. In summary, this invention, through its cleverly designed airflow adjustment mechanism and dust removal mechanism, not only expands the airflow guidance range but also significantly improves gas flow efficiency, thereby achieving a more efficient and reliable ventilation and heat dissipation effect, ensuring the stable operation of the diesel generator set's heat dissipation structure in complex environments.

An arc-shaped dust discharge trough 11 is provided on one side of the guide slide 5.

[0025] Please see Figure 2The translation assembly includes a translation slide rail 101, a translation motor 102, and a translation lead screw 103. The translation slide rail 101 is installed inside the heat sink housing 2. A translation motor 102 is installed at one end of the translation slide rail 101, and a translation lead screw 103 is installed at the output end of the translation motor 102. Starting the translation motor 102 will drive the translation lead screw 103 to rotate. The translation assembly also includes a connecting rod 104 and a translation slider 105. A translation slider 105 is installed on the side wall of the translation lead screw 103, and the translation slider 105 is threadedly connected to the translation lead screw 103. A connecting rod 104 is provided on one side of the heat sink 2, and the other end of the translation connecting rod 4 is fixedly connected to the other side of the translation slider 105. The translation screw 103 can drive the translation slider 105 to move in parallel. The heat dissipation assembly includes a fixed frame 201, an adjusting shaft 202 and an adjusting ventilation plate 203. A fixed frame 201 is provided inside one side of the heat dissipation box 2. Multiple sets of adjusting ventilation plates 203 are provided inside the fixed frame 201. Two sets of adjusting shafts 202 are provided on the upper and lower sides of the adjusting ventilation plate 203. The adjusting shafts 202 can drive the adjusting ventilation plate 203 to rotate.

[0026] Please see Figures 3-6 The heat dissipation assembly also includes a drive motor 204, a drive shaft 205, and a drive impeller 206. A drive motor 204 is located on one side of the adjusting ventilation plate 203. A drive shaft 205 is located at the output end of the drive motor 204, and a drive impeller 206 is located at one end of the drive shaft 205. Starting multiple drive motors 204 drives the drive impeller 206 to rotate via their respective drive shafts 205, thereby generating a powerful airflow to provide all-around ventilation and heat dissipation for the interior of the container 1, ensuring the generator set can operate stably at a suitable temperature. The transmission assembly includes a translation gear plate 301 and an adjusting gear 302. A translation gear plate 301 is located at one end of the connecting rod 104, and an adjusting gear 302 is located on the side wall of the adjusting shaft 202. Engaging with the translation gear plate 301, the translation gear plate 301, during its movement, utilizes the meshing relationship between the adjusting gear 302 and the adjusting shaft 202 to achieve the range of rotation of the adjusting shaft 202. The dust removal assembly includes a support bracket 401, an active motor 402, an active shaft 403, and an active impeller 404. The support bracket 401 is provided on the bottom wall of the translation slider 105. The active motor 402 is provided above one side of the support bracket 401. The active shaft 403 is provided at the output end of the active motor 402. The active impeller 404 is provided at one end of the active shaft 403. After the active motor 402 is started, the active shaft 403 drives the active impeller 404 to rotate, generating airflow to smoothly discharge the dust in the arc-shaped dust discharge trough 11 to the outside of the heat dissipation box 2 through the guide groove on the lower side.

[0027] During operation, the diesel generator set's cooling system first activates multiple drive motors 204, which, through their respective drive shafts 205, drive impellers 206 to rotate. This generates a powerful airflow, providing comprehensive ventilation and cooling to the interior of the container 1, ensuring the generator set can operate stably at a suitable temperature.

[0028] Simultaneously, by activating the translation motor 102, the translation screw 103 is driven to rotate. The translation screw 103 further pushes the translation gear plate 301 to move parallel through the connecting rod 104. During the movement, the translation gear plate 301 utilizes the meshing relationship between the adjusting gear 302 and the adjusting shaft 202 to achieve the range of rotation of the adjusting shaft 202. This rotational action drives the adjusting ventilation plate 203 and its driving motor 204 and driving impeller 206 to rotate together, thereby realizing flexible adjustment of the airflow direction, greatly expanding the airflow guidance range, and further enhancing the ventilation and heat dissipation effect.

[0029] Furthermore, the translation slider 105 is connected to the guide slide 7 via the translation link 4. As the translation slider 105 moves, the guide slide 7 also slides on the guide slide 6. The movement of the guide slide 7 drives the rotation of the rotating gears 9 on both sides on the fixed toothed plates 3, which in turn drives the cleaning brush cylinders 10 on both sides to rotate via the rotating shafts 8 on both sides. These cleaning brush cylinders 10 are in close contact with both sides of the fixed ventilation plate 12, effectively removing dust and impurities attached to the ventilation plate, significantly improving the air circulation efficiency, and further enhancing the ventilation and heat dissipation capabilities.

[0030] Additionally, the cleaned dust and impurities fall into the arc-shaped dust discharge trough 11 below the fixed ventilation plate 12. At this time, the translation slider 105 drives the active motor 402 to move parallel above the arc-shaped dust discharge trough 11 via the support bracket 401. After the active motor 402 is started, the active shaft 403 drives the active impeller 404 to rotate, generating airflow that smoothly discharges the dust in the arc-shaped dust discharge trough 11 to the outside of the heat sink 2 through the guide groove on the lower side.

[0031] In summary, this utility model, through its cleverly designed airflow adjustment mechanism and dust removal mechanism, not only expands the airflow guidance range but also significantly improves the gas circulation efficiency, thereby achieving a more efficient and reliable ventilation and heat dissipation effect and ensuring the stable operation of the diesel generator set's heat dissipation structure in complex environments.

[0032] Through the above steps, when the diesel generator set's cooling structure is in use, multiple cooling components are first activated to rotate, generating a powerful airflow to provide all-around ventilation and cooling for the interior of the container 1. Simultaneously, the translation component is activated, driving the cooling components to rotate within a range via the transmission component, allowing for flexible adjustment of the airflow direction. Furthermore, as the translation component moves, the guide slide 7 slides on the guide slide rod 6. The movement of the guide slide 7 drives the rotation of the rotating gears 9 on both sides of the fixed toothed plates 3, which in turn drives the cleaning brushes 10 on both sides to rotate via the rotating shafts 8. These cleaning brushes 10 are tightly fitted to both sides of the fixed ventilation plate 12, effectively removing dust and debris adhering to the ventilation plate. The airflow efficiency is significantly improved, further enhancing the ventilation and heat dissipation capabilities. Additionally, the cleaned dust and impurities fall into the arc-shaped ash discharge trough 11 below the fixed ventilation plate 12. At this time, the translation component drives the dust removal component to move parallel above the arc-shaped ash discharge trough 11, activating the dust removal component to generate airflow that smoothly discharges the dust in the arc-shaped ash discharge trough 11 through the lower guide groove to the outside of the heat dissipation box 2. In summary, this utility model, through its cleverly designed airflow adjustment mechanism and dust removal mechanism, not only expands the airflow guidance range but also significantly improves the airflow efficiency, thereby achieving a more efficient and reliable ventilation and heat dissipation effect, ensuring the stable operation of the diesel generator set's heat dissipation structure in complex environments.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
