Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, specifically to a modular power station. Background Technology

[0002] A modular power station comprises a modular unit, generator set, batteries, and inverters, with the generator set being the primary power generation equipment. This generator set includes a generator, engine, and cooling components, with different power outputs selected based on actual needs. Generator set operation is often accompanied by noise, primarily generated from two sources: mechanical noise from the engine block and generator operation, and intake and exhaust noise from the engine. Higher engine power means more work done per unit time, faster piston speed, and more drastic pressure changes within the combustion chamber, resulting in greater noise. Therefore, noise reduction is a crucial consideration in the design and manufacturing of modular power stations.

[0003] Existing technology utilizes sound-absorbing materials to fill the bulkheads of the modular housing to block generator noise. In terms of internal structural design, the generator is typically placed in a separate compartment, forming a generator room, with a muffler installed on the engine exhaust pipe. While this method can reduce noise to some extent, other auxiliary components coexist with the generator in the generator room. Especially for high-power generators, a radiator is required, which needs to be located near the exhaust louvers. This not only occupies a significant amount of space within the generator room, but noise also leaks through the exhaust louvers, hindering overall noise reduction. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the existing technology and propose a modular power station. For high-power modular power stations, through reasonable structural design, the noise of the modular power station can be reduced without affecting the heat dissipation performance of the generator set.

[0005] The solution is a modular power station, comprising a generator room and an electrical room separated within a modular unit. The generator room is equipped with several partitions dividing it into zones I, II, III, IV, and V. Zones I, III, and V are located in the upper part of the generator room, with zone V located between zones I and III. Zones II and IV are located in the lower part of the generator room. Zone I is equipped with a first noise reduction component, zone II is equipped with a generator set, zone III is equipped with a second noise reduction component, and zone IV is equipped with a cooling water tank connected to the generator set via piping. Zone V is equipped with a silencer, and the generator set's exhaust pipe is connected to the silencer. The end of the generator room away from the electrical room is equipped with exhaust louvers, through which hot air is discharged from zones III and IV.

[0006] Preferably, Zone I is located above the generator, and Zone I is provided with two air inlet louvers symmetrically installed on the side wall of the cabin. The side of the air inlet louvers closest to the unit room is connected to the first noise reduction component. A baffle is fixed between the two first noise reduction components, and the first noise reduction component extends toward the baffle.

[0007] Preferably, the partition between Zone II and Zone III is an inclined partition with an axial flow fan installed on it, and the partition between Zone II and Zone IV is a vertical partition. The lower end of the inclined partition is fixedly connected to the upper end of the vertical partition. The upper end of the inclined partition is inclined toward Zone II and fixed to the upper bulkhead of the container. The axial flow fan draws air from Zone II to Zone III.

[0008] Preferably, the upper end of the inclined bulkhead is provided with a corner piece, the angle of the corner piece is consistent with the angle between the inclined bulkhead and the upper bulkhead of the container, one side of the corner piece is fixedly connected to the inclined bulkhead, and the other side of the corner piece is fixedly connected to the upper bulkhead of the container.

[0009] Preferably, the second noise reduction component in zone III consists of several noise reduction units, with adjacent noise reduction units arranged alternately.

[0010] Preferably, the noise reduction unit includes a perforated plate, a sound-absorbing material, and an aluminum plate. The sound-absorbing material and the rectangular tube are pressed together between the perforated plate and the aluminum plate, and the perforated plate is disposed on the side with the noise source.

[0011] Preferably, the partition includes a noise reduction unit and multiple rectangular tubes, which form a frame structure. For partitions with a large area, rectangular tubes are added in the middle of the frame as reinforcing ribs, and noise reduction units of matching size are fixedly filled in the hollow part of the frame.

[0012] Preferably, the cabin panels are filled with rock wool.

[0013] Preferably, there are two unit rooms, with an electrical room located between the two unit rooms, and the two unit rooms are symmetrically arranged about the electrical room.

[0014] Beneficial effects: 1. This utility model separates and isolates the mechanical noise and exhaust noise of the generator set, physically controls the noise source, and prevents the superposition of the two noises. Compared with the existing technology where the noise source is concentrated in the same space, it has a better noise suppression effect. 2. To reduce mechanical noise, the air inlet louvers are combined with the first noise reduction component, and the axial flow fan is combined with the second noise reduction component. This arrangement of noise reduction components with the airflow direction in the unit room reduces mechanical noise while ensuring the heat dissipation of the generator set. 3. This technical solution is universally applicable; power plants of different power ratings can all be divided into zones according to this technical solution to achieve the purpose of isolation and noise reduction.

[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] like Figures 1 to 5As shown, a modular power station includes a generator room 1 and an electrical room 2, which are separated and housed within a modular unit. The generator room 1 is equipped with several partitions that divide it into zones I, II, III, IV, and V. Zones I, III, and V are located in the upper part of the generator room 1, with zone V located between zones I and III. Zones II and IV are located in the lower part of the generator room 1. Zone I is equipped with a first noise reduction component 10, zone II is equipped with a generator set, zone III is equipped with a second noise reduction component 7, and zone IV is equipped with a cooling water tank connected to the generator set via pipes. Zone V is equipped with a silencer, and the generator set's exhaust pipe is connected to the silencer. The end of the generator room 1 away from the electrical room 2 is equipped with an exhaust louver 11, through which zones III and IV discharge hot air. The unit room 1 not only generates noise but also high temperatures during operation, requiring airflow for heat dissipation. However, noise may leak from Zone I during air intake, so a first noise reduction component 10 is installed to effectively prevent noise leakage from the air intake area. Zone II is the area where mechanical noise is generated. The noise is partially suppressed by the rebound of the bulkhead and the cabin wall. The hot air in Zone II needs to be discharged through Zone III. At this time, the noise in Zone II will spread towards Zone III, so a second noise reduction component 7 is installed for noise reduction. Zones III and IV share the exhaust area, reducing the structural complexity of multiple exhaust louvers 11 and rationally unifying the exhaust path. The full-area exhaust louver 11 design increases the exhaust area and improves exhaust efficiency. Engine exhaust gas enters Zone V through a pipe. Under the action of the bulkhead, Zone V is not connected to Zone II. The exhaust noise in Zone V will not be superimposed by the mechanical noise in Zone II. The bulkhead in Zone V only reduces exhaust noise, reflecting the effective noise reduction method of zoned noise treatment.

[0020] Zone I is located above generator 13 and engine 14. Zone I is equipped with two symmetrically mounted air inlet louvers 9 on the side wall of the cabin. The side of the air inlet louvers 9 closest to the unit compartment 1 is connected to the first noise reduction component 10. A baffle 12 is fixed between the two first noise reduction components 10, and the first noise reduction components 10 extend towards the baffle 12. Compared with the engine body, the generator is smaller in volume. The space above the generator is fully utilized to set up two air inlet louvers 9 to increase the air intake volume and improve the heat dissipation efficiency in the unit compartment 1. External air passes through the air inlet louvers 9 and the first noise reduction component 10, encounters the baffle 12, flows downward, and then flows downward from both sides of the generator. This structure increases the airflow path and can effectively remove the heat of the unit in Zone II.

[0021] The partition between Zone II and Zone III is an inclined partition 3, on which an axial flow fan 4 is installed. The partition between Zone II and Zone IV is a vertical partition 5, with the lower end of the inclined partition 3 fixedly connected to the upper end of the vertical partition 5. The upper end of the inclined partition 3 is inclined towards Zone II and fixed to the upper bulkhead of the cabin. The axial flow fan 4 draws air from Zone II to Zone III. Before installing noise reduction components, priority should be given to ensuring effective control of the generator set's heat radiation. The axial flow fan can improve the airflow efficiency within the cabin. Compared to the conventional vertical installation method in existing technologies, the inclined installation method is more adaptable to large-size axial flow fans, providing a wider power selection range for high-power cabin power stations.

[0022] The upper end of the inclined bulkhead 3 is provided with a corner piece 8. The angle of the corner piece 8 is consistent with the angle between the inclined bulkhead 3 and the upper bulkhead of the container. One side of the corner piece 8 is fixedly connected to the inclined bulkhead 3, and the other side of the corner piece 8 is fixedly connected to the upper bulkhead of the container. Since the main function of the inclined bulkhead 3 is to install the axial flow fan 4, in order to avoid cracking caused by the vibration of the axial flow fan 4, the upper end of the inclined bulkhead 3 is fixed to the upper bulkhead of the container to enhance the stability of the inclined bulkhead 3. As the size of the axial flow fan 4 increases, the inclination of the inclined bulkhead 3 increases, thus reducing the height design of the container.

[0023] The second noise reduction component 7 in Zone III consists of several noise reduction units, with adjacent units arranged alternately. Noise is continuously weakened by the staggered arrangement of these noise reduction units. The more noise reduction units there are, the better the noise reduction effect, but this can affect heat dissipation. Therefore, the number of noise reduction units is determined based on the product's noise specifications and testing.

[0024] The noise reduction unit includes a perforated plate 701, a sound-absorbing material 702, and an aluminum plate 703. The sound-absorbing material 702 and a rectangular tube 704 are pressed together between the perforated plate 701 and the aluminum plate 703. The perforated plate 701 is positioned on the side with the noise source. When noise passes through the perforated plate 701, part of it is reflected back by the perforated plate 701, and part of it enters the sound-absorbing material 702 through the holes. The sound-absorbing material 702 is a porous material, so some noise is absorbed by the sound-absorbing material 702, and a small portion reaches the aluminum plate 703 and is reflected back into the sound-absorbing material 702, thus achieving effective noise reduction.

[0025] The partition includes noise reduction units and multiple rectangular tubes 704. The rectangular tubes 704 form a frame structure. For partitions with larger areas, rectangular tubes 704 are added in the middle of the frame as reinforcing ribs. Noise reduction units of matching sizes are fixedly filled in the hollow part of the frame. As the main sound insulation component, the partition is responsible for separating mechanical noise and smoke exhaust noise. For the partition between Zone II and Zone V, the perforated plate 701 faces Zone V; for other partitions in Zone II, the perforated plate 701 faces Zone II.

[0026] The modular cabin panels are filled with rock wool. The rock wool filling inside the panels ensures sound insulation and noise reduction, achieving a triple noise reduction effect through cabin sound insulation, bulkhead sound insulation, and further noise reduction by noise reduction components.

[0027] The modular power station has two generator rooms (1), with an electrical room (2) located between them, and the two generator rooms (1) are symmetrically arranged about the electrical room (2). For high-power modular power stations, the conventional layout is to place both generators in the same generator room (1) to save space and wiring, but this usually results in a significant increase in noise within the generator room (1). This solution, designed for dual-generator modular power stations, separates the two generators at opposite ends of the electrical room (2). Both generators can be connected to the electrical room (2) at close range, and each generator is individually soundproofed, isolating the noise sources and minimizing noise leakage.

[0028] Working principle: When the modular power station is working, the generator set generates noise and a large amount of heat. Part of the heat is collected in the cooling water tank in area IV, and the other part is drawn into area III by the axial flow fan 4. The noise is diffused in the direction of air intake and exhaust under the restriction of the partition, and is absorbed by the first noise reduction component 9 and the second noise reduction component 7. At the same time, outside air enters from area I into area II under the action of negative pressure, completing the air flow in the cabin. The noise from the engine exhaust is reflected and consumed in area V.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
