Description

Technical Field

[0001] This invention belongs to the field of generator set technology, and relates to a containerized diesel generator set, particularly a cooling and noise reduction type containerized diesel generator set. Background Technology

[0002] Diesel generator sets, as an important backup or primary power source, are widely used in applications where power supply continuity is extremely important, such as data centers, communication base stations, hospitals, large-scale event support, and power supply in remote areas. As people's requirements for noise control in their work and living environments continue to increase, the noise control and emission levels of generator sets have become key indicators for measuring their technological advancement.

[0003] Existing containerized diesel generator sets typically install the diesel engine, generator, and auxiliary equipment directly inside a standard container. However, in pursuit of high noise reduction, these sets often involve excessive sealing of the container or the use of complex silencing channels, which severely impedes airflow and reduces heat dissipation efficiency. Furthermore, while existing noise reduction measures are effective at absorbing mid-to-high frequency airborne noise, they have limited attenuation of low-frequency vibration noise generated by the diesel engine. Current solutions often treat noise reduction, heat dissipation, and vibration isolation as independent modules, lacking a holistic system-wide collaborative design. This "piecemeal" design results in bulky equipment, low energy efficiency, and potential reliability issues.

[0004] Therefore, we propose a cooling and noise reduction containerized diesel generator set. Through a sealed source and multi-layer isolation design, it comprehensively reduces noise from the noise source, the container, and the air duct, significantly reducing operating noise. It adopts a system with independent hot and cold air ducts to simultaneously and efficiently cool the equipment and engine coolant in the cabin. It has strong heat dissipation capacity and no heat backflow. Equipped with a multi-stage vibration isolation structure, it can effectively suppress broadband vibration, ensure stable operation, and reduce structural noise transmission. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a cooling and noise reduction containerized diesel generator set. The technical problem this invention aims to solve is: how to effectively reduce noise propagation during generator operation, improve the efficiency of the heat dissipation system, and achieve multi-level vibration isolation, thereby improving the overall environmental adaptability and operational stability of the generator set.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A cooling and noise reduction type containerized diesel generator set includes a container assembly. A silencer exhaust assembly is fixed to the upper end of the container assembly. The container assembly contains a vibration isolation base assembly, a heat dissipation assembly, a soundproof chamber, a control cabinet, and a power distribution cabinet. The soundproof chamber is mounted on the vibration isolation base assembly. The diesel generator assembly is located inside the soundproof chamber. Several rectangularly distributed vibration damping components are provided between the diesel generator assembly and the bottom of the soundproof chamber. The vibration damping components are connected to an external air pump through a multi-way valve. The heat dissipation assembly is located on the front side of the soundproof chamber. The diesel generator assembly is provided with an exhaust pipe that is connected to the silencer exhaust assembly. The diesel generator assembly is provided with a water inlet pipe and a water outlet pipe that are respectively connected to the heat dissipation assembly.

[0008] The container assembly includes the container body. Inside the container body, from front to back, there are three sound insulation panels: a first sound insulation panel, a second sound insulation panel, and a third sound insulation panel. These panels divide the interior of the container assembly into a front heat dissipation area, a power generation area, a rear heat dissipation area, and an electrical equipment area. The first sound insulation panel has an inverted U-shaped structure. The heat dissipation components are fitted under the first sound insulation panel, with one part of the heat dissipation components located inside the power generation area and the other part extending into the front heat dissipation area. The second sound insulation panel is equipped with several electric exhaust fans, all of which are connected to the sound insulation chamber through pipes and are electrically connected to the control cabinet. The vibration isolation seat assembly, the sound insulation chamber, and the diesel generator assembly are all located inside the power generation area. The control cabinet and the distribution cabinet are arranged side by side in the electrical equipment area. The control cabinet is electrically connected to the heat dissipation components and the external air pump, and the distribution cabinet is electrically connected to the diesel generator assembly.

[0009] The working principle of this invention is as follows: During operation, the diesel generator assembly generates electrical energy, exhaust gas, heat, vibration, and noise. The soundproof chamber isolates most of the motor's operating noise. At the same time, in conjunction with the container assembly's container body, soundproof panel one, soundproof panel two, and soundproof panel three, noise transmission is isolated, thus achieving noise reduction. The exhaust gas is transported to the silencer exhaust assembly through the exhaust gas pipe, and is discharged after being purified by the silencer exhaust assembly. The generated heat is guided to the heat dissipation assembly through the internal circulation via the water outlet pipe.

[0010] The interior of the container is divided into a front heat dissipation area, a power generation area, a rear heat dissipation area, and an electrical equipment area by sound insulation panels one, two, and three, forming an orderly airflow channel. The external cooling airflow enters the power generation area after being filtered and silenced by the sound-absorbing air inlet louvers one. The control cabinet adjusts the cooling fan for forced cooling. Subsequently, a portion of the cooling airflow is blown by the cooling fan to the heat dissipation components, carrying away the heat from the heat dissipation components and forming hot air. The hot air is discharged from the front heat dissipation area, and the cooled water is returned to the diesel generator set to form a cooling water circulation, thereby reducing the operating temperature of the generator set.

[0011] To suppress noise and vibration, the diesel generator assembly is placed inside a soundproof chamber and is subjected to airbag vibration isolation through several vibration damping components. These components are connected to an external air pump via multi-way valves, and the airbag pressure of the vibration damping components can be adjusted by the air pump. The entire soundproof chamber is subjected to primary vibration isolation through the vibration isolation seat assembly at the bottom. At the same time, electric exhaust fans installed on the second soundproof panel are responsible for enhancing the ventilation of the soundproof chamber, allowing another part of the cooling airflow to enter the soundproof chamber and reduce the temperature inside. Hot air is discharged to the rear heat dissipation area through several electric exhaust fans and then discharged from the rear heat dissipation area, thereby achieving multiple cooling and multi-level vibration isolation and noise reduction. Finally, the electrical energy is output from the distribution cabinet, and the overall operation is coordinated and controlled by the control cabinet.

[0012] The container body has exhaust louvers and operating doors at its front and rear ends, respectively. The front of the container body has a sound-absorbing and rectifying grille located between the exhaust louvers and the sound insulation panel. The left and right sides of the container body have sound-absorbing air outlet louvers and sound-absorbing air inlet louvers, and each sound-absorbing air inlet louver is equipped with a dust filter. The sound-absorbing air outlet louvers and the sound-absorbing air inlet louvers are symmetrically arranged. The sound-absorbing air inlet louvers are located on the left and right sides of the power generation area, and the sound-absorbing air outlet louvers are located on the left and right sides of the rear heat dissipation area. The left and right sides of the container body have side inspection doors, with the two side inspection doors located on the left and right sides of the power generation area, respectively.

[0013] With the above structure, the container body forms an organized airflow channel and convenient maintenance access through the exhaust louvers at the front end, the sound-absorbing air inlet louvers on the left and right sides, and the sound-absorbing air outlet louvers. The outside air enters the power generation area after passing through the sound-absorbing air inlet louvers on both sides and being filtered by the dust filter on them. After being silenced, it enters the cooling water cooling area. Then, the hot air formed after participating in the cooling is transported into the front heat dissipation area. After being reduced in noise and guided by the sound-absorbing rectifier grille, it is discharged through the exhaust louvers.

[0014] The cooling airflow entering the soundproof compartment carries away the heat inside, and is then discharged to the rear heat dissipation area by several electric exhaust fans, and discharged through the silencer louvers on both sides of the rear heat dissipation area. At the same time, for ease of operation and maintenance, an operating door is provided at the rear of the container, and side inspection doors are provided on both the left and right sides corresponding to the power generation area, which facilitates maintenance and use.

[0015] The side walls and top of the container body are covered with a composite sound insulation layer, which consists of a high-damping water-based acrylic board, a multi-layer ceramic fiber composite cotton board, a micro-perforated support board, and a perforated inner lining board from the outside to the inside.

[0016] Using the above structure, the composite board achieves sound insulation and noise reduction functions through a combination of multiple materials: the high-damping water-based acrylic board can consume vibration energy and suppress the transmission of structural noise; the middle multi-layer ceramic fiber composite cotton board serves as the core sound-absorbing layer, absorbing and attenuating a large number of sound waves; the inner micro-perforated support plate and the innermost perforated lining plate together constitute the micro-perforated plate sound-absorbing structure, further optimizing the reduction effect of mid-to-high frequency noise. The composite structure from the outside to the inside forms multiple acoustic barriers from sound insulation, damping and vibration reduction to sound absorption, thereby improving the overall sound insulation performance of the enclosure.

[0017] The vibration isolation seat assembly includes a rectangular fixing ring, an upper connecting plate, a lower connecting plate, and two rubber vibration isolation pads. The two rubber vibration isolation pads are bolted side by side between the upper and lower connecting plates. The lower connecting plate is fixedly installed at the inner bottom of the power generation area of ​​the container body. Both the lower and upper connecting plates are rectangular plates. The outer dimensions of the upper and lower connecting plates are equal to the inner circle size of the rectangular fixing ring. The upper edge of the upper connecting plate is rounded. The outer side of the rectangular fixing ring has several evenly spaced mounting holes. The inner side of the rectangular fixing ring has a guide limiting groove with a trapezoidal cross-section, which gradually narrows from the inner side to the outer side of the rectangular fixing ring. The side of the lower connecting plate has several evenly spaced fixing screw holes, the number and position of which correspond to the mounting holes. The lower connecting plate is installed on the inner side of the rectangular fixing ring by several bolts that pass through the mounting holes and are screwed into the corresponding fixing screw holes.

[0018] Using the above structure, two rubber vibration isolation pads placed between the upper and lower connecting plates absorb and isolate vibrations from above, achieving basic vibration isolation. The lower connecting plate is fixed to the inner bottom of the container's power generation area and is bolted through the mounting holes on the outside of the rectangular fixing ring to the corresponding fixing screw holes on the side of the lower connecting plate, thus securing the entire component. Its unique horizontal limiting function is achieved by the trapezoidal cross-section guide limiting groove on the inner side of the rectangular fixing ring and the rounded chamfer on the upper connecting plate. When the upper connecting plate undergoes elastic displacement due to vibration, its rounded chamfer will slide along the inclined surface of the guide limiting groove and embed itself therein, thereby effectively limiting the horizontal displacement of the soundproof cabin and its internal equipment, preventing excessive movement, and ensuring the stability and reliability of the entire vibration isolation system.

[0019] The soundproof chamber has an inspection plate fixed with bolts at the top, two sound-absorbing air inlet louvers at the front, and several exhaust pipes at the rear. The number of exhaust pipes is matched with the number of electric exhaust fans, and the exhaust pipes are connected to the electric exhaust fans at the corresponding positions through pipes.

[0020] With the above structure, the upper part of the soundproof cabin is equipped with a maintenance plate fixed by bolts, which facilitates the maintenance and repair of the equipment inside the cabin. The second sound-absorbing air inlet louver serves as an air intake channel, which allows external air to enter while effectively reducing noise leakage. Several exhaust pipes connected to the interior are matched with electric exhaust fans in corresponding positions to form a forced ventilation system, which efficiently exhausts the hot air inside the cabin to the rear heat dissipation area, thereby achieving the organization, circulation and heat dissipation of airflow inside the cabin while ensuring sound insulation and sealing.

[0021] The diesel generator assembly includes a mounting base, on which a diesel engine and a generator are mounted. The output shaft of the diesel engine is connected to the rotating shaft of the generator. The generator is electrically connected to the distribution cabinet. The water inlet pipe is connected to the water pump integrated on the diesel engine. The water outlet pipe is connected to the thermostat integrated on the diesel engine. The exhaust pipe is located on the diesel engine.

[0022] With the above structure, the diesel engine serves as the power source, and its output shaft is connected to the generator's shaft. This converts chemical energy into mechanical energy and drives the generator to rotate, thereby generating electrical energy. The generated electrical energy is then transmitted to the distribution cabinet via cables for distribution, control, and output. Simultaneously, to maintain the engine's normal operating temperature, an integrated water pump drives the cooling water circulation. The cooling water flows into the engine through the inlet pipe to absorb heat. After absorbing heat, the high-temperature cooling water flows through the outlet pipe connected to the engine thermostat to the cooling components, completes heat dissipation, and then recirculates, thus achieving effective temperature control of the diesel engine.

[0023] The heat dissipation assembly includes a base, on which two finned heat sinks and two cooling fans are fixed. The two cooling fans are located behind the two finned heat sinks respectively. The two finned heat sinks are arranged side by side and locked under a sound insulation plate. The two finned heat sinks extend into the front heat dissipation area. The inlet pipe and outlet pipe are connected to the two finned heat sinks through a multi-way valve.

[0024] With the above structure, two finned radiators are fixed on the base and arranged side by side. Each finned radiator is equipped with a cooling fan on its rear side. The two finned radiators are engaged below the sound insulation plate and extend into the front heat dissipation area, thereby isolating the heat dissipation area from the power generation area. High-temperature cooling water from the diesel generator assembly is diverted into the two finned radiators through the outlet pipe and multi-way valve. The forced airflow generated by the operation of the cooling fan blows across the heat dissipation surface of the finned radiator, carrying away its heat and discharging it into the front heat dissipation area. The cooled water is collected through the inlet pipe and multi-way valve and then flows back to the diesel engine, forming a highly efficient forced air cooling circulation heat dissipation path.

[0025] The silencer exhaust assembly includes a silencer exhaust stack with two fixed pipe clamps arranged symmetrically front and rear on the silencer exhaust stack. The two fixed pipe clamps are fixedly installed on the upper end of the container body, and the exhaust pipe is connected to the silencer exhaust stack.

[0026] With the above structure, the silencer exhaust stack is securely installed on the upper part of the container body through two symmetrically arranged fixing pipe clamps, ensuring the safety and stability of the exhaust pipeline under the vibration of the unit operation. The exhaust gas generated by the diesel generator set during operation is transported to the silencer exhaust stack through the exhaust pipe. The exhaust stack has an internal sound-absorbing structure, which can effectively reduce exhaust noise and purify the exhaust gas. After sound absorption and purification, the exhaust gas is finally discharged into the outside atmosphere, thereby achieving effective control of exhaust noise.

[0027] The vibration damping components include fixed flanges and airbag bases. The fixed flanges of several vibration damping components are fixed below the mounting base, and the airbag bases are fixed to the inner bottom of the soundproof chamber. The airbag bases are hollow inside and have air inlet pipes that are connected to the inside of the airbag bases. The air inlet pipes of several vibration damping components are connected to an external air pump through multi-way valves. A guide sleeve is provided at the upper end of the airbag base and is connected to the airbag base. The guide sleeve has several circumferentially distributed vent holes. A vibration isolation airbag is provided between the fixed flanges and the airbag bases. The guide sleeve is located inside the vibration isolation airbag. A guide rod that matches the guide sleeve is fixed below the fixed flanges. The guide rod is slidably disposed inside the guide sleeve. The guide rod is hollow inside and has several circumferentially distributed vent holes.

[0028] With the above structure, the fixed flange is fixed below the mounting base, and the airbag base is fixed to the inner bottom of the soundproof chamber. The vibration isolation airbag is set between the two to form the core vibration isolation unit. The airbag base is hollow inside and is connected to an external air pump through an air inlet pipe via a multi-way valve, so that the pressure of the vibration isolation airbag can be adjusted according to the operating conditions. The guide sleeve at the upper end of the airbag base extends into the vibration isolation airbag, while the hollow guide rod below the fixed flange slides in the guide sleeve. This fit allows vertical vibration displacement while effectively limiting excessive lateral displacement. At the same time, the first vent on the guide sleeve and the second vent on the guide rod work together to ensure the air pressure balance inside and outside the vibration isolation airbag, ensuring the stable performance of its vibration reduction.

[0029] The sound insulation board 1, sound insulation board 2 and sound insulation board 3 are all sandwich panels, and the middle sandwich layer is sound-absorbing cotton.

[0030] With the above structure, the sound insulation panels 1, 2 and 3 are filled with sound-absorbing cotton, which can effectively absorb and attenuate the sound wave energy passing through the panel, converting sound energy into heat energy. While playing the role of isolation, it actively absorbs sound. Together with the composite panel wall of the container body and the sound insulation compartment, it forms a multi-layer sound insulation system, which works together to prevent the propagation of noise from the power generation area to the front heat dissipation area, the rear heat dissipation area and the electrical equipment area, thereby significantly improving the sound insulation of the container and the overall noise reduction effect.

[0031] Compared with existing technologies, this cooling and noise-reducing containerized diesel generator set has the following advantages:

[0032] 1. By constructing a multi-level noise reduction structure to block noise propagation, the core noise source, the diesel generator assembly, is sealed in a dedicated soundproof cabin, achieving source control; the main body of the container assembly adopts a composite panel structure, and the built-in soundproof panel one, soundproof panel two, and soundproof panel three are all filled with sound-absorbing cotton, forming an efficient internal acoustic barrier; the ventilation channel and exhaust channel are integrated with a sound-absorbing structure, which works together to reduce airborne and structural sound transmission during unit operation.

[0033] 2. Cooling air enters through the first silencer air inlet louver. Part of it enters the cabin through the second silencer air inlet louver on the front side of the soundproof cabin for heat exchange. Then, the electric exhaust fan on the second soundproof panel draws the air to the rear heat dissipation area through the exhaust pipe to avoid heat backflow and reduce the temperature inside the cabin. The other part of the cooling air is used by the heat dissipation components to cool the engine coolant and is forced out through the front heat dissipation area to achieve efficient heat dissipation.

[0034] 3. Vibration reduction of the foundation is achieved through vibration isolation seat assembly. The guide limiting groove and the upper connecting plate cooperate to limit horizontal displacement. The pressure of the vibration isolation airbags of several vibration isolation components can be adjusted by an external air pump to achieve self-adaptation of vibration isolation stiffness. It can effectively isolate broadband vibration. The sliding cooperation between the guide rod and the guide sleeve provides vertical guidance and lateral limitation. Multi-stage vibration isolation reduces the vibration and structural noise transmitted to the container foundation. Attached Figure Description

[0047] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0048] like Figure 1 - Figure 11 As shown, this cooling and noise reduction containerized diesel generator set includes a container assembly 1. A silencer exhaust assembly 2 is fixed to the upper end of the container assembly 1. Inside the container assembly 1, there is a vibration isolation seat assembly 7, a heat dissipation assembly 8, a soundproof chamber 6, a control cabinet 4, and a power distribution cabinet 5. The soundproof chamber 6 is installed on the vibration isolation seat assembly 7. The diesel generator assembly 3 is installed inside the soundproof chamber 6. Several vibration damping components are arranged in a rectangular pattern between the diesel generator assembly 3 and the bottom of the soundproof chamber 6. Several vibration damping components are connected to an external air pump through a multi-way valve. The heat dissipation assembly 8 is located on the front side of the soundproof chamber 6. The diesel generator assembly 3 is equipped with an exhaust pipe 28, which is connected to the silencer exhaust assembly 2. The diesel generator assembly 3 is equipped with a water inlet pipe 23 and a water outlet pipe 25, which are respectively connected to the heat dissipation assembly 8.

[0049] The container assembly 1 includes a container body 15. Inside the container body 15, from front to back, there are three sound insulation panels: a first sound insulation panel 16, a second sound insulation panel 17, and a third sound insulation panel 21. These panels divide the interior of the container assembly 1 into a front heat dissipation area, a power generation area, a rear heat dissipation area, and an electrical equipment area. The first sound insulation panel 16 has an inverted U-shaped structure. The heat dissipation component 8 is fitted under the first sound insulation panel 16, with one part of the heat dissipation component 8 located inside the power generation area and the other part extending into the front heat dissipation area. The second sound insulation panel 17 is equipped with several electric exhaust fans 18, all of which are connected to the soundproof cabin 6 via pipes. The electric exhaust fans 18 are also electrically connected to the control cabinet 4. The vibration isolation seat assembly 7, the soundproof cabin 6, and the diesel generator assembly 3 are all located inside the power generation area. The control cabinet 4 and the power distribution cabinet 5 are arranged side by side in the electrical equipment area. The control cabinet 4 is electrically connected to the heat dissipation component 8 and the external air pump, and the power distribution cabinet 5 is electrically connected to the diesel generator assembly 3.

[0050] In this embodiment, the diesel generator assembly 3 generates electrical energy, exhaust gas, heat, vibration and noise during operation. The soundproof chamber 6 isolates most of the motor operating noise. At the same time, it works with the container body 15, soundproof panel 16, soundproof panel 17 and soundproof panel 21 of the container assembly 1 to isolate noise transmission and achieve noise reduction. The exhaust gas is transported to the silencer exhaust assembly 2 through the exhaust pipe 28 and discharged after being purified by the silencer exhaust assembly 2. The generated heat is guided to the heat dissipation assembly 8 through the water outlet pipe 25 through internal circulation.

[0051] The interior of the container body 15 is divided into a front heat dissipation area, a power generation area, a rear heat dissipation area, and an electrical equipment area by sound insulation panels 16, 17, and 21, forming an orderly airflow channel. The external cooling airflow enters the power generation area after being filtered and silenced by the sound-absorbing air inlet louvers 12. The control cabinet 4 adjusts the cooling fan 27 for forced cooling. Subsequently, a portion of the cooling airflow is blown by the cooling fan 27 to the heat dissipation component 8, which carries away the heat of the heat dissipation component 8 and forms hot air. The hot air is discharged from the front heat dissipation area, and the cooled water is returned to the diesel generator assembly 3 to form a cooling water circulation and reduce the operating temperature of the generator set.

[0052] To suppress noise and vibration, the diesel generator assembly 3 is placed inside the soundproof chamber 6 and is subjected to airbag vibration isolation through several vibration damping components. These vibration damping components are all connected to an external air pump through multi-way valves, and the airbag pressure of the vibration damping components can be adjusted by the air pump. The entire soundproof chamber 6 is subjected to primary limiting vibration isolation through the vibration isolation seat assembly 7 at the bottom. At the same time, the electric exhaust fan 18 installed on the soundproof panel 17 is responsible for enhancing the ventilation of the soundproof chamber 6, allowing another part of the cooling airflow to enter the soundproof chamber 6 and reduce the temperature inside the soundproof chamber 6. The hot air is discharged to the rear heat dissipation area through several electric exhaust fans 18 and discharged from the rear heat dissipation area, thereby achieving multiple cooling and multi-level vibration isolation and noise reduction. Finally, the electrical energy is output by the distribution cabinet 5, and the overall operation is coordinated and controlled by the control cabinet 4.

[0053] The container body 15 has exhaust louvers 10 and operating doors 11 at its front and rear ends, respectively. The front of the container body 15 has a sound-absorbing and rectifying grille 9, which is located between the exhaust louvers 10 and the sound insulation panel 16. The left and right sides of the container body 15 are equipped with sound-absorbing air outlet louvers 14 and sound-absorbing air inlet louvers 12, and the sound-absorbing air inlet louvers 12 are equipped with dust filters. The sound-absorbing air outlet louvers 14 and the sound-absorbing air inlet louvers 12 on both sides are symmetrically arranged. The sound-absorbing air inlet louvers 12 are located on the left and right sides of the power generation area, and the sound-absorbing air outlet louvers 14 are located on the left and right sides of the rear heat dissipation area. The left and right sides of the container body 15 are equipped with side inspection doors 13, which are located on the left and right sides of the power generation area, respectively.

[0054] In this embodiment, the container body 15 forms an organized airflow channel and convenient maintenance entrance through the exhaust louver 10 at its front end, the silencer air inlet louvers 12 on the left and right sides, and the silencer air outlet louvers 14. External air enters the power generation area after passing through the silencer air inlet louvers 12 on both sides and being filtered by the dust filter on them. After being silenced, it enters the cooling water cooling area. Subsequently, the hot air formed after participating in the cooling is transported into the front heat dissipation area. After being noise-reduced and guided by the silencer rectifier grille 9, it is discharged through the exhaust louver 10.

[0055] The cooling airflow entering the soundproof compartment 6 carries away the heat inside the soundproof compartment 6, and is then discharged to the rear heat dissipation area by several electric exhaust fans 18, and discharged through the sound-absorbing air louvers 14 on both sides of the rear heat dissipation area. At the same time, for the convenience of operation and maintenance, an operating door 11 is provided at the rear of the container, and side inspection doors 13 are provided on both the left and right sides at the corresponding positions of the power generation area, which facilitates maintenance and use.

[0056] The side walls and top of the container body 15 are covered with a composite sound insulation layer, which consists of a high-damping water-based acrylic board, a multi-layer ceramic fiber composite cotton board, a micro-perforated support board, and a perforated inner lining board from the outside to the inside.

[0057] In this embodiment, the composite board achieves sound insulation and noise reduction through a combination of multiple materials: the high-damping water-based acrylic board can consume vibration energy and suppress the transmission of structural noise; the middle multi-layer ceramic fiber composite cotton board serves as the core sound-absorbing layer, absorbing and attenuating a large number of sound waves; the inner micro-perforated support plate and the innermost perforated lining plate together constitute the micro-perforated plate sound-absorbing structure, further optimizing the reduction effect of mid-to-high frequency noise. The composite structure from the outside to the inside forms multiple acoustic barriers from sound insulation, damping and vibration reduction to sound absorption, thereby improving the overall sound insulation performance of the enclosure.

[0058] The vibration isolation seat assembly 7 includes a rectangular fixing ring 32, an upper connecting plate 31, a lower connecting plate 33, and two rubber vibration isolation pads 37. The two rubber vibration isolation pads 37 are bolted side-by-side between the upper connecting plate 31 and the lower connecting plate 33. The lower connecting plate 33 is fixedly installed at the inner bottom of the power generation area of ​​the container body 15. Both the lower connecting plate 33 and the upper connecting plate 31 are rectangular plates. The outer dimensions of both the upper connecting plate 31 and the lower connecting plate 33 are equal to the inner circle size of the rectangular fixing ring 32. The upper edge of the upper connecting plate 31 is rounded. The outer side of the fixed ring 32 is provided with several equally spaced mounting holes 34, and the inner side of the rectangular fixed ring 32 is provided with a guide limiting groove 36. The cross-section of the guide limiting groove 36 is trapezoidal, and the guide limiting groove 36 gradually shrinks from the inner side of the rectangular fixed ring 32 to the outer side. The side of the lower connecting plate 33 is provided with several equally spaced fixing screw holes 35. The number and position of the fixing screw holes 35 correspond to the mounting holes 34. The lower connecting plate 33 is provided with several bolts that pass through the mounting holes 34 and are screwed into the corresponding fixing screw holes 35 on the inner side of the rectangular fixed ring 32.

[0059] In this embodiment, two rubber vibration isolation pads 37, placed between the upper connecting plate 31 and the lower connecting plate 33, absorb and isolate vibrations from above, achieving basic vibration isolation. The lower connecting plate 33 is fixed to the inner bottom of the power generation area of ​​the container body 15, and is bolted to the corresponding fixing screw hole 35 on the side of the lower connecting plate 33 by passing through the mounting hole 34 on the outside of the rectangular fixing ring 32, thereby securing the entire component. Its unique horizontal limiting function is achieved by the trapezoidal cross-section guide limiting groove 36 on the inner side of the rectangular fixing ring 32 cooperating with the rounded chamfer on the upper connecting plate 31. When the upper connecting plate 31 undergoes elastic displacement due to vibration, its rounded chamfer will slide along the inclined surface of the guide limiting groove 36 and embed itself therein, thereby effectively limiting the horizontal displacement amplitude of the soundproof cabin 6 and its internal equipment, preventing excessive movement, and ensuring the stability and reliability of the entire vibration isolation system.

[0060] The soundproof chamber 6 has an inspection plate fixed with bolts at the top. The front of the soundproof chamber 6 has a sound-absorbing air inlet louver 29. The rear of the soundproof chamber 6 has several exhaust pipes 30. All exhaust pipes 30 are connected to the interior of the soundproof chamber 6. The number of exhaust pipes 30 matches the number of electric exhaust fans 18. The exhaust pipes 30 are connected to the electric exhaust fans 18 at the corresponding positions through pipes.

[0061] In this embodiment, the upper end of the soundproof chamber 6 is provided with a maintenance plate fixed by bolts, which facilitates the maintenance and repair of the equipment inside the chamber. The sound-absorbing air inlet louver 29 serves as an air intake channel, which effectively reduces noise leakage while allowing external air to enter. Several exhaust pipes 30 connected to the interior are matched with the electric exhaust fans 18 at the corresponding positions to form a forced ventilation system, which efficiently exhausts the hot air inside the chamber to the rear heat dissipation area, thereby achieving the organization, circulation and heat dissipation of airflow inside the chamber while ensuring sound insulation and sealing.

[0062] The diesel generator assembly 3 includes a mounting base 45, on which a diesel engine 19 and a generator 20 are mounted. The output shaft of the diesel engine 19 is connected to the rotating shaft of the generator 20. The generator 20 is electrically connected to the distribution cabinet 5. The water inlet pipe 23 is connected to the water pump integrated on the diesel engine 19. The water outlet pipe 25 is connected to the thermostat integrated on the diesel engine 19. The exhaust pipe 28 is located on the diesel engine 19.

[0063] In this embodiment, the diesel engine 19 serves as a power source, with its output shaft connected to the rotating shaft of the generator 20. This converts chemical energy into mechanical energy and drives the generator 20 to rotate, thereby generating electrical energy. The generated electrical energy is transmitted to the distribution cabinet 5 via cables for distribution, control, and output. Simultaneously, to maintain the normal operating temperature of the engine, an integrated water pump drives the cooling water circulation. The cooling water flows into the engine through the inlet pipe 23 to absorb heat. The high-temperature cooling water after absorbing heat then flows through the outlet pipe 25 connected to the engine thermostat to the heat dissipation assembly 8, completes heat dissipation, and recirculates, thereby achieving effective temperature control of the diesel engine 19.

[0064] The heat dissipation assembly 8 includes a base 26, on which two finned heat sinks 22 and two cooling fans 27 are fixed. The two cooling fans 27 are located on the rear side of the two finned heat sinks 22 respectively. The two finned heat sinks 22 are inserted side by side under the sound insulation plate 16. The two finned heat sinks 22 extend into the front heat dissipation area. The water inlet pipe 23 and the water outlet pipe 25 are both connected to the two finned heat sinks 22 through multi-way valves.

[0065] In this embodiment, two finned radiators 22 arranged side by side are fixed on the base 26, and a cooling fan 27 is provided on the rear side of each finned radiator 22. The two finned radiators 22 are engaged under the sound insulation plate 16 and extend into the front heat dissipation area, thereby isolating the heat dissipation area from the power generation area. The high-temperature cooling water from the diesel generator assembly 3 is diverted into the two finned radiators 22 through the outlet pipe 25 via a multi-way valve. The forced airflow generated by the operation of the cooling fan 27 blows across the heat dissipation surface of the finned radiator 22, carrying away its heat and discharging it into the front heat dissipation area. The cooled water is collected through the inlet pipe 23 via a multi-way valve and then flows back to the diesel engine 19, forming an efficient forced air cooling circulation heat dissipation path.

[0066] The silencer exhaust assembly 2 includes a silencer exhaust pipe 46, on which two fixed pipe clamps 24 are symmetrically arranged. The two fixed pipe clamps 24 are fixedly installed on the upper end of the container body 15, and the exhaust pipe 28 is connected to the silencer exhaust pipe 46.

[0067] In this embodiment, the silencer exhaust stack 46 is securely installed on the upper end of the container body 15 by two symmetrically arranged fixing clamps 24, ensuring the safety and stability of the exhaust pipeline under the vibration of the unit operation. The exhaust gas generated by the diesel generator assembly 3 during operation is transported to the silencer exhaust stack 46 through the exhaust pipe 28. The exhaust stack has an internal sound-absorbing structure, which can effectively reduce exhaust noise and purify the exhaust gas. After sound absorption and purification, the exhaust gas is finally discharged into the outside atmosphere, thereby achieving effective control of exhaust noise.

[0068] The vibration damping assembly includes a fixed flange 38 and an airbag base 41. The fixed flanges 38 of several vibration damping assemblies are fixed below the mounting base 45. The airbag bases 41 are all fixed to the inner bottom of the soundproof chamber 6. The airbag base 41 is hollow inside and has an air inlet pipe 40 connected to the interior of the airbag base 41. The air inlet pipes 40 of several vibration damping assemblies are connected to an external air pump through a multi-way valve. A guide sleeve 42 is provided at the upper end of the airbag base 41. 2. It is connected to the airbag base 41. The guide sleeve 42 has several circumferentially distributed vent holes 44. A vibration isolation airbag 39 is provided between the fixed flange 38 and the airbag base 41. The guide sleeve 42 is located inside the vibration isolation airbag 39. A guide rod 43 matching the guide sleeve 42 is fixed below the fixed flange 38. The guide rod 43 is slidably disposed inside the guide sleeve 42. The guide rod 43 is hollow inside and has several circumferentially distributed vent holes 2.

[0069] In this embodiment, the fixed flange 38 is fixed below the mounting base 45, and the airbag base 41 is fixed to the inner bottom of the soundproof chamber 6. A vibration isolation airbag 39 is set between the two to form the core vibration isolation unit. The airbag base 41 is hollow inside and is connected to an external air pump through an air inlet pipe 40 via a multi-way valve, so that the pressure of the vibration isolation airbag 39 can be adjusted according to the operating conditions. The guide sleeve 42 at the upper end of the airbag base 41 extends into the vibration isolation airbag 39, and the hollow guide rod 43 below the fixed flange 38 slides in the guide sleeve 42. This mating pair allows vertical vibration displacement while effectively limiting excessive lateral displacement. At the same time, the vent hole 44 on the guide sleeve 42 and the vent hole 43 on the guide rod 43 work together to ensure the air pressure balance inside and outside the vibration isolation airbag 39, ensuring the stable performance of its vibration reduction.

[0070] Sound insulation board 16, sound insulation board 27 and sound insulation board 321 are all sandwich panels, with sound-absorbing cotton in the middle.

[0071] In this embodiment, the interior of sound insulation panel 16, sound insulation panel 17, and sound insulation panel 21 is filled with sound-absorbing cotton, which can effectively absorb and attenuate the sound wave energy passing through the panel, converting sound energy into heat energy. While playing the role of isolation, it actively absorbs sound. Together with the composite panel wall of the container body 15 and the sound insulation compartment 6, they form a multi-layer sound insulation system, which synergistically prevents the propagation of noise from the power generation area to the front heat dissipation area, the rear heat dissipation area, and the electrical equipment area, thereby significantly improving the sound insulation of the compartment and the overall noise reduction effect.

[0072] The working principle of this invention is as follows: When the diesel engine 19 of the diesel generator assembly 3 drives the generator 20, it generates electrical energy, exhaust gas, heat, vibration, and noise. The electrical energy is output through the distribution cabinet 5, and the exhaust gas is transported through the exhaust pipe 28 to the silencer chimney 46 installed on the upper part of the container body 15. The chimney has an internal sound-absorbing structure, which can effectively reduce exhaust gas emission noise and purify the exhaust gas. After sound absorption and purification, the exhaust gas is finally discharged into the external atmosphere, thereby achieving effective control of exhaust gas noise.

[0073] Thermal management is accomplished through two independent systems working together. High-temperature cooling water from diesel generator assembly 3 is diverted through outlet pipe 25 and multi-way valve into two finned radiators 22. The forced airflow generated by the operation of cooling fan 27 blows over the heat dissipation surface of finned radiator 22, carrying away its heat and discharging it into the front heat dissipation area. The cooled water is then collected through inlet pipe 23 and multi-way valve and flows back to diesel engine 19, forming an efficient forced air cooling circulation heat dissipation path.

[0074] Meanwhile, after the external air is filtered and silenced by the silencer louver 12, part of it enters the cabin through the silencer louver 29 on the front side of the soundproof cabin 6 and takes away the heat in the cabin. Then, the electric exhaust fan 18 on the soundproof panel 217 draws it to the rear heat dissipation area through the exhaust pipe 30 and finally discharges it through the silencer louver 14. The other part of the air is used to cool the heat dissipation component 8. The hot air formed is guided and silenced by the silencer rectifier grille 9 and discharged through the front exhaust louver 10, realizing the separation of hot and cold air ducts.

[0075] Noise reduction is achieved through multiple structures, including the container body 15 made of composite panels, the sound insulation panel 16, the sound insulation panel 27, the sound insulation panel 3 21 filled with sound-absorbing cotton, and the sound insulation cabin 6 that encloses the generator set, which together form a multi-layer acoustic barrier.

[0076] Basic vibration isolation is provided by the rubber vibration isolation pad 37 between the upper connecting plate 31 and the lower connecting plate 33, and horizontal limiting is achieved by the guide limiting groove 36 of the rectangular fixing ring 32 and the rounded chamfer of the upper connecting plate 31. Several vibration damping components are installed between the base 45 and the bottom of the soundproof chamber 6. An adjustable airbag vibration isolation unit is formed by the fixing flange 38, the airbag base 41 and the vibration isolation airbag 39. Its pressure is regulated by an external air pump through the air inlet pipe 40 and the multi-way valve, and the lateral displacement is limited by the sliding cooperation between the guide rod 43 and the guide sleeve 42 to achieve adaptive vibration reduction. The operation of the entire system, including the cooling fan 27, the electric exhaust fan 18 and the air pump, is coordinated and controlled by the control cabinet 4, thereby integrating the functions of high-efficiency power generation, intelligent cooling, multi-level vibration isolation and deep noise reduction.

[0077] In summary, by constructing a multi-level noise reduction structure to block noise propagation, the core noise source, the diesel generator assembly 3, is sealed within a dedicated soundproof chamber 6, achieving source control; the main body of the container assembly 1 adopts a composite panel structure, and the built-in soundproof panels 16, 17, and 21 are all filled with sound-absorbing cotton, forming an efficient internal acoustic barrier; the ventilation and exhaust channels are integrated with sound-absorbing structures, working together to reduce airborne and structural noise transmission during unit operation;

[0078] Cooling air enters through the silencer louver 12. Part of it enters the cabin through the silencer louver 29 on the front side of the soundproof cabin 6 for heat exchange, and is then drawn out to the rear heat dissipation area by the electric exhaust fan 18 on the soundproof panel 217 through the exhaust pipe 30 to avoid heat backflow and reduce the cabin temperature. The other part of the cooling air is used by the heat dissipation component 8 to cool the engine coolant and is forced out through the front heat dissipation area to achieve efficient heat dissipation.

[0079] The vibration reduction of the foundation is achieved by the vibration isolation seat assembly 7. The guide limiting groove 36 cooperates with the upper connecting plate 31 to limit the horizontal displacement. The pressure of the vibration isolation airbags 39 of several vibration isolation components can be adjusted by an external air pump to achieve self-adaptation of the vibration isolation stiffness. It can effectively isolate broadband vibration. The sliding cooperation between the guide rod 43 and the guide sleeve 42 provides vertical guidance and lateral limiting. Multi-level vibration isolation reduces the vibration and structural noise transmitted to the container foundation.
