Description

Technical Field

[0001] This utility model relates to the field of diesel generator set technology, specifically a stacked containerized diesel generator set. Background Technology

[0002] In industrial production, engineering construction, and other fields, diesel generator sets are widely used as emergency power sources or regular power sources. To facilitate transportation, installation, and management, containerized diesel generator sets have emerged, among which stackable containerized diesel generator sets are favored due to their space-saving design.

[0003] However, existing stacked containerized diesel generator sets still have some drawbacks in practical use: the air outlets are mostly simple straight-out designs, resulting in a large diffusion range of the exhausted hot air, and there is no targeted airflow guiding structure, causing hot air to easily form backflow around the unit. Due to the stacked arrangement, the hot air exhausted from the lower unit diffuses upwards, and if the air inlet of the upper unit is not properly positioned, it is very easy to draw in this high-temperature air, forming a "vicious thermal cycle." For example, the air outlets of some stacked units are located at the top of the container, and the bottom of the upper container is too close to the air outlet of the lower unit. The hot air exhausted from the lower unit is directly drawn into the air inlet of the upper unit without effective guidance, causing the intake air temperature of the upper unit to rise by 10-15°C, which is seriously beyond the normal operating temperature range of the unit.

[0004] To address these issues, we designed a stackable containerized diesel generator set. Utility Model Content

[0005] The purpose of this invention is to provide a stackable containerized diesel generator set to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a stackable containerized diesel generator set, including a first container and a second container, which are stacked vertically in a longitudinal direction. A tray is fixedly installed inside both the first and second containers, and the generator set body is fixedly installed on the top surface of the tray. Heat dissipation components are provided on both the first and second containers, and a locking assembly is provided between the first and second containers. The second container is detachably connected to the first container through the locking assembly.

[0007] Furthermore, the heat dissipation component includes louvers, which are fixedly installed inside the first housing and positioned below the tray. A guide shroud is fixedly connected to the top surface of the first housing, and an air outlet duct is fixedly connected to the top of the guide shroud.

[0010] Furthermore, a lock hole is provided inside the first fixing block, and a movable through groove is provided through the top wall of the first fixing block.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a stackable container diesel generator set, including a first container 1 and a second container 2, which are stacked vertically in the longitudinal direction. This stacking method can make full use of space. A tray 3 is fixedly installed inside both the first container 1 and the second container 2. The generator set body 4 is fixedly installed on the top surface of the tray 3, and the tray 3 provides stable support for the generator set body 4.

[0020] Both the first housing 1 and the second housing 2 are equipped with heat dissipation components 5. Each heat dissipation component 5 includes louvers 51. The louvers 51 are fixedly installed inside the first housing 1 and positioned below the tray 3. The louvers 51 consist of multiple gravity-adjustable baffles, which are suspended by top hinges. They automatically open at a certain angle during negative pressure suction and close to prevent dust when the machine stops, effectively introducing cool air. A guide hood 52 is fixedly connected to the top surface of the first housing 1. The bottom of the guide hood 52 is connected to the unit's exhaust port, and the top of the guide hood 52 is fixedly connected to an exhaust duct 53. The air duct 53 is connected to the interior of the first housing 1 through the air guide shroud 52. The outlet end of the air duct 53 extends to the side of the first housing 1 and the outlet height of the air duct 53 exceeds the bottom plate of the second housing 2 to prevent hot air from being sucked in from the upper layer. A spiral guide vane 54 is fixedly installed inside the air duct 53. The spiral guide vane 54 converts the axial airflow into a rotating jet. It uses the Kerndale effect to adhere to the inner wall of the air duct 53 and move, accelerating away from the area inside the first housing 1. The hot airflow inside the first housing 1 is ejected obliquely upward at a certain angle, completely avoiding the air intake area of ​​the second housing 2.

[0021] A locking assembly 6 is provided between the first housing 1 and the second housing 2. There are four locking assemblies 6, each located at one of the four corners of the top surface of the first housing 1, for a more secure connection. Each locking assembly 6 includes a first fixing block 61, which is fixedly installed on the top surface of the first housing 1. The first fixing block 61 has a locking hole 67 and a through-hole 68 on its top wall. A second fixing block 62 is fixedly connected to the bottom surface of the second housing 2, and the second fixing block 62 is movably disposed within it. There is a movable block 63, and a locking tongue 64 is fixedly connected to the bottom of the movable block 63. The locking tongue 64 passes through the bottom wall of the second fixed block 62 and is slidably connected to the second fixed block 62. A first limiting block 65 is fixedly connected to one side of the bottom of the locking tongue 64, and a second limiting block 66 is fixedly connected to the top side of the locking tongue 64 away from the first limiting block 65. A buffer pad 69 is fixedly connected to the top of the locking tongue 64. The buffer pad 69 is located between the movable block 63 and the second limiting block 66. The buffer pad 69 is made of high-density rubber and can play a buffering role.

[0022] The second housing 2 is detachably connected to the first housing 1 via a locking assembly 6. The second fixing block 62 at the bottom of the second housing 2 is aligned with the first fixing block 61 at the top of the first housing 1. The second housing 2 is then continuously lowered. When the lower inclined surface of the first limiting block 65 on the right side of the latch 64 contacts the movable slot 68 on the first fixing block 61, a leftward bias force is generated on the latch 64, causing the latch 64 to slide to the left along the lower inclined surface of the first limiting block 65. When the latch 64 contacts the left side of the movable slot 68... When the latch 64 is guided downward into the lock hole 67, when the left side of the moving through groove 68 touches the second limiting block 66 set on the left side of the latch 64, the latch 64 is pushed to the right, so that the latch 64 slides completely into the lock hole 67 and enters the locked state. When it is necessary to separate the first fixing block 61 and the second fixing block 62, an upward force is required to make the second limiting block 66 set on the left side of the latch 64 slide out of the lock hole 67. The upward force continues to act, which will continuously pull the latch 64 upward until it is completely disengaged from the lock hole 67.

[0023] An insect-proof net 7 is fixedly installed below the louver 51 to prevent insects from entering the box. In practice, the generator set body 4 is installed on the tray 3 inside the first housing 1 and the second housing 2. When stacking is required, the second fixing block 62 at the bottom of the second housing 2 is aligned with the first fixing block 61 at the top of the first housing 1, and the second housing 2 is lowered. The two are locked by the locking assembly 6. During operation, the heat generated by the generator set body 4 is discharged through the heat dissipation assembly 5. Cold air enters through the louver 51, and hot air is discharged through the guide shroud 52 and the air outlet duct 53. The spiral guide vane 54 accelerates the discharge of hot air and prevents hot air from being sucked into the upper housing. When disassembly is required, an upward force is applied to the second housing 2 to disengage the locking tongue 64 from the locking hole 67.

[0024] Working principle: The first housing 1 receives air from the bottom. The louvers 51 consist of multiple gravity-adjustable baffles, which are suspended by top hinges. They automatically open at a certain angle when drawing in air under negative pressure and close to prevent dust when the machine stops. The first housing 1 forces hot air to the side through the top guide shroud 52 and the exhaust duct 53. The spiral guide vanes 54 fixed inside the exhaust duct 53 convert the axial airflow into a rotating jet. Utilizing the Kerndale effect, the jet adheres to the inner wall of the exhaust duct 53 and accelerates away from the area inside the first housing 1. The hot air inside the first housing 1 is ejected obliquely upward at a certain angle, completely avoiding the air intake area of ​​the second housing 2. By blocking the channel through which the hot air in the first housing 1 is drawn in from the upper layer, the hot airflow path is completely isolated. At the same time, the heat dissipation efficiency is automatically optimized using the airflow dynamics characteristics, with no additional energy consumption.

[0025] The second housing 2 is the same size as the first housing 1. The second fixing block 62 at the bottom of the second housing 2 is aligned with the first fixing block 61 at the top of the first housing 1. Then, the second housing 2 is continuously lowered. When the lower slope of the first limiting block 65 on the right side of the latch 64 touches the movable through groove 68 on the first fixing block 61, a leftward bias force is generated on the latch 64, causing the latch 64 to slide to the left along the lower slope of the first limiting block 65. When the latch 64 touches the left side of the movable through groove 68, the latch 64 is guided downward into the lock hole 67. When the left side of the movable through groove 68 touches the second limiting block 66 on the left side of the latch 64, the latch 64 is pushed to the right, so that the latch 64 slides completely into the lock hole 67 and enters the locked state.

[0026] When it is necessary to separate the first fixing block 61 from the second fixing block 62, an upward force is required to make the second limiting block 66 on the left side of the latch 64 slide out of the lock hole 67. The upward force continues to act, which will pull the latch 64 upward until it is completely disengaged from the lock hole 67.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
