[0036] The following will be combined with Figures 1-6 to elaborate in detail on a containerized multi-module diesel generator set involved in the embodiments of this application. It should be noted that the following embodiments are only used to explain this application and do not constitute a limitation to this application.

[0037] Embodiment 1:

[0038] See Figures 1-6 As shown, a container 1 type multi-module diesel generator set. This case is a container 1 type modular unit with a total output power of 2000 KW, consisting of 4 sets of 500 KW generator set units. It includes: container 1, support base 11, base-mounted fuel tank 12, diesel generator set 9, air inlet 6, air outlet 2, control cabinet 7, and exhaust pipe 10;

[0039] The external dimensions of container 1 are length × width × height: 12000 mm × 3200 mm × 3000 mm, and the material is galvanized cold-rolled sheet with a thickness of 2 mm. The static load of container 1 is 30 tons, the dynamic load is 40.5 tons, the protection level is IP45, and the noise at a distance of 1 meter is about 102 dB. It is mainly composed of 4 sets of generator units, 5 high-voltage solid insulation cabinets, and 1 parallel operation control cabinet 7. The length × width × height of a single unit is: 3560 mm × 1320 mm × 2145 mm. The length × width × height of the high-voltage solid insulation cabinet and the parallel operation control cabinet 7 is: 420 mm × 900 mm × 1850 mm.

[0040] The support base 11 is arranged at the bottom of container 1 to play a supporting role; the support base 11 is made of galvanized cold-rolled sheet. The support base 11 is used to carry the diesel generator set 9 and protect the base-mounted fuel tank 12 at the bottom, preventing the diesel generator set 9 from directly acting on the base-mounted fuel tank 12.

[0041] Container 1 adopts a base-mounted fuel tank 12, and the base-mounted fuel tank 12 is configured inside the bottom plate of container 1 below the support base 11; the number of the base-mounted fuel tanks 12 matches the number of the diesel generator sets 9, and each diesel generator set 9 is adapted to one base-mounted fuel tank 12, and multiple base-mounted fuel tanks 12 are connected and interconnected through pipelines. The capacity of each base-mounted fuel tank 12 is 630 L. The four base-mounted fuel tanks 12 are connected and interconnected through pipelines. A fuel filling port is provided on the side of container 1, and an on-site oil circuit control box is configured inside container 1.

[0042] Of course, it should be noted that the containerized diesel generator set 9 can also adopt an external fuel tank, and the external fuel tank supplies oil to each diesel generator set through an oil pipe.

[0043] Multiple diesel generator sets 9 are arranged on the support base 11 and are respectively communicated with the base fuel tank 12; two air inlets 6 are respectively opened on the side plates on both sides of the container 1; multiple air outlets 2 are arranged on the top plate of the container 1 and are respectively arranged opposite to the air outlets of multiple diesel generator sets 9.

[0044] The air inlets 6 of the container 1 are located on both sides, with two shutter windows on each side, a total of 4 shutter windows, and a total air inlet area of 14 square meters to meet the normal operation of the unit. The exhaust air for heat dissipation is diverted to the top of the container 1, and the exhaust port size of a single unit is about 1200mm * 1200mm. There are also several enclosures formed by the air duct partitions 8 in the container 1. The enclosures are communicated with the air outlets 2 of the diesel generator sets 9 and are used to discharge the air discharged from the air outlets 2 of the diesel generator sets 9 through the air outlets 2 on the top of the container 1. The setting of the enclosures further enables the air discharged from the air outlets 2 of each diesel generator set 9 to be discharged only from the corresponding exhaust port.

[0045] The control cabinet 7 is arranged in the container 1. The dimensions of the high-voltage solid insulation cabinet and the parallel operation control cabinet 7 are: 420mm * 900mm * 1850mm; it is used to control multiple diesel generator sets 9 respectively.

[0046] The exhaust pipe 10 is arranged on the top of the container 1 and is used to discharge the exhaust gas generated by multiple diesel generator sets 9. The exhaust pipe 10 is respectively communicated with the mufflers of each diesel generator set 9. This can further reduce the generation of noise.

[0047] The containerized diesel generator set 9 is based on the container 1 structure, and multiple small-power diesel generator sets are arranged in the container 1 in a preset order. Each small-power diesel generator set 9 in the container 1 corresponds to an incoming line cabinet. The outgoing line ends of the incoming line cabinets are arranged side by side with the incoming line ends of the outgoing line cabinets. The parallel operation controller detects that conditions such as voltage, frequency, and phase meet the parallel operation requirements and closes the corresponding incoming line cabinets. Users can control the outgoing line cabinet to supply power to the load according to needs, which realizes the parallel operation output of multiple diesel generator sets and meets the requirements of high-power loads. The incoming line cabinets and the outgoing line cabinets in the container 1 both adopt solid insulation cabinets, ensuring the use of the switch cabinets in the narrow space of the container 1.

[0048] When the actual required power of the user is less than the parallel operation power of the generator sets, the number of operating generator sets can be increased or decreased according to the required power of the user, which improves the efficiency, economic benefits and protects the environment. For example: the on-site situation may only require the generator sets to provide 400KW. For a traditional large generator set of 2000KW, it actually provides 20% of the load power, and the fuel cannot be fully burned, emitting serious black smoke, polluting the environment and reducing the usage efficiency. Now, the container 1 type multi-module diesel generator set 9 is adopted. Four small power generator sets of 500KW are used to form an output of 2000KW. The on-site only requires the generator sets to provide 400KW, and only starting one small power diesel generator set 9 can meet the requirements. It actually provides 80% of the load power, not only improving the economic benefits, but also enabling the fuel to be fully burned and protecting the environment.

[0049] Adopting the form of the container 1 type multi-module diesel generator set 9 reduces the maintenance difficulty, maintenance cost and maintenance expenses. For a large power diesel generator set 9, it weighs dozens of tons and has a large volume, making disassembly and maintenance difficult. However, it is relatively easy for small power diesel generator sets; the maintenance cost for a single unit is also lower; only the units that have reached the operating time are maintained, and the cost is also lower compared to the maintenance of large generator sets.

[0050] In some embodiments, access doors 4 are provided on the side walls of the front and rear sides of the container 1, and louvers 3 are provided on the access doors 4 to further improve the air intake effect.

[0051] In some embodiments, drain holes are provided at the bottom of the side walls of the front and rear sides of the container 1. The drain holes can timely drain the accumulated water inside the box body and improve safety.

[0052] In some embodiments, lifting lugs 5 are provided on the container 1 for easy movement and hoisting.

[0053] In some embodiments, a number of sound-absorbing cotton is provided on the inner wall of the container 1. The sound-absorbing cotton can further reduce the noise when the container 1 type diesel generator set 9 is working.

[0054] The above are only the preferred embodiments of the present invention and are used to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
