[0036] The following will combine Figures 1-6 This application provides a detailed description of a containerized multi-module diesel generator set according to its embodiments. It is worth noting that the following embodiments are merely illustrative of this application and do not constitute a limitation thereof.

[0037] Example 1:

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

[0039] Container 1 has external dimensions of 12000mm (L*W*H) and is made of galvanized cold-rolled steel sheet with a thickness of 2mm. Container 1 has a static load of 30 tons, a dynamic load of 40.5 tons, an IP45 protection rating, and a noise level of approximately 102dB at one meter. It mainly consists of 4 generator units, 5 high-voltage solid-insulation cabinets, and 1 parallel control cabinet 7. The dimensions of a single generator unit are 3560mm*1320mm*2145mm. The dimensions of the high-voltage solid-insulation cabinet and parallel control cabinet 7 are 420mm*900mm*1850mm.

[0040] The support base 11 is located at the bottom of the container 1 and serves a supporting function; the support base 11 is made of galvanized cold-rolled steel. The support base 11 is used to support the diesel generator set 9 and also protects the base-type fuel tank 12 at the bottom, preventing the diesel generator set 9 from directly impacting the base-type fuel tank 12.

[0041] Container 1 uses a base-mounted fuel tank 12, which is disposed within the bottom plate of container 1 under the supporting base 11. The number of base-mounted fuel tanks 12 matches the number of diesel generator sets 9, with each diesel generator set 9 being equipped with one base-mounted fuel tank 12, and multiple base-mounted fuel tanks 12 are interconnected via pipelines. Each base-mounted fuel tank 12 has a capacity of 630L. The four base-mounted fuel tanks 12 are interconnected via pipelines. A refueling port is provided on the side of container 1, and a local fuel line control box is installed inside container 1.

[0042] Of course, it should be noted that the container type 1 diesel generator set 9 can also use an external fuel tank, and the external fuel tank is supplied with fuel by a fuel pipe to each diesel generator set.

[0043] Multiple diesel generator sets 9 are mounted on a support base 11 and are respectively connected to a base-type fuel tank 12; two air inlets 6 are respectively opened on the side panels on both sides of the container 1; multiple air outlets 2 are mounted on the top panel of the container 1 and are respectively arranged opposite to the air outlets of the multiple diesel generator sets 9.

[0044] The air inlets 6 of container 1 are located on both sides, with two louvers on each side, totaling four louvers and a total air intake area of ​​14 square meters to meet the normal operation of the generator set. Exhaust air is directed to the top of container 1 for heat dissipation. The exhaust vent size of a single generator set is approximately 1200mm*1200mm. Inside container 1, there are also several enclosures composed of air duct partitions 8. These enclosures are connected to the exhaust vents 2 of the diesel generator sets 9, allowing the air exhausted from the exhaust vents 2 of the diesel generator sets 9 to be discharged through the exhaust vents 2 on the top of container 1. The enclosures further ensure that the air exhausted from the exhaust vents 2 of each diesel generator set 9 can only be discharged from the corresponding exhaust vent.

[0045] The control cabinet 7 is installed inside the container 1. The dimensions of the high-voltage solid-insulated cabinet and parallel control cabinet 7 are 420mm*900mm*1850mm. It is used to control multiple diesel generator sets 9 respectively.

[0046] The exhaust pipe 10 is installed on the top of the container 1 and is used to exhaust the exhaust gases generated by the multiple diesel generator sets 9. The exhaust pipe 10 is connected to the muffler of each diesel generator set 9. This can further reduce noise generation.

[0047] The container-type diesel generator set 9 is based on the structure of container 1, with multiple small-power diesel generator sets arranged in a preset order inside container 1. Each small-power diesel generator set 9 inside container 1 corresponds to an incoming line cabinet. The outgoing lines of the incoming line cabinets are arranged side by side with the incoming lines of the outgoing line cabinets. The parallel controller detects that the voltage, frequency, phase, and other conditions meet the parallel operation requirements and closes the corresponding incoming line cabinet. Users can control the outgoing line cabinets to supply power to the load as needed. This enables multiple diesel generator sets to operate in parallel, meeting the needs of high-power loads. Both the incoming and outgoing line cabinets inside container 1 use solid insulation cabinets, ensuring the usability of the switchgear within the confined space of container 1.

[0048] When the actual power demand of the user is less than the parallel power of the generator sets, the number of operating generator sets can be adjusted according to the user's power demand, improving efficiency, economic benefits, and environmental protection. For example, if the site conditions only require a generator set to provide 400KW, a traditional large generator set (2000KW) would only provide 20% of the load power, resulting in incomplete combustion of fuel, severe black smoke emissions, environmental pollution, and reduced efficiency. Now, using a containerized multi-module diesel generator set (model 9), four 500KW small-power units can form a 2000KW output. Only a single small-power diesel generator set (model 9) is needed to meet the requirement, providing 80% of the load power. This not only improves economic efficiency but also ensures complete combustion of fuel, protecting the environment.

[0049] The use of a containerized, multi-module diesel generator set reduces maintenance difficulty and costs, as well as upkeep expenses. While high-power diesel generator sets weigh 20-30 tons and are bulky, making disassembly and repair difficult, this is relatively easier for smaller generator sets. The maintenance cost per unit is also lower; maintenance is only required for units that have reached their operating time, resulting in lower costs compared to maintaining larger units.

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

[0051] In some embodiments, drainage holes are provided at the bottom of the side walls on both the front and rear sides of the container 1. These drainage holes can promptly drain water from inside the container, improving safety.

[0052] In some embodiments, the container 1 is provided with lifting lugs 5 to facilitate movement and lifting.

[0053] In some embodiments, the inner wall of the container 1 is provided with a plurality of sound-absorbing cotton. The sound-absorbing cotton can further reduce the noise of the container 1 type diesel generator set 9 during operation.

[0054] The above description is only a preferred embodiment of the present utility model and is used to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
