Description

Technical Field

[0001] This utility model relates to the technical field of power generation equipment, and in particular to a dual power pack structure for a diesel generator set. Background Technology

[0002] Currently, most public places are equipped with diesel generators for emergency power supply. However, individual diesel generators may malfunction, making emergency power supply impossible. This can cause huge losses in places that require emergency response, such as hospitals, data centers, and emergency rescue facilities. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a dual power pack structure for a diesel generator set. Depending on the actual power load, a single unit can be selected for operation, reducing energy consumption and improving operating efficiency under low load conditions; under high load conditions, both units can be started and run simultaneously to meet the high power demand; and the reliability of power supply is improved. When one generator unit fails, the other generator unit can quickly take over the entire power supply task, ensuring the continuity of power supply and reducing losses caused by power outages.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A dual power pack structure for a diesel generator set, comprising at least two power generation units and a control system, wherein the two power generation units are arranged side by side; Each of the power generation units includes: an engine and a generator connected to the output of the engine; The control system is connected to the engine and generator of the two power generation units respectively.

[0005] The aforementioned dual power pack structure for diesel generator sets further includes: a base frame, on which two generator units are arranged side-by-side and fixedly installed.

[0006] The aforementioned dual power pack structure for diesel generator sets further includes: an electrical connection switchgear assembly, which is signal-connected to the two generator units respectively. When the two generator units are running simultaneously, the electrical connection switchgear assembly controls the two generator units to operate in parallel or switch between them. The base frame forms two parallel installation spaces. One of the installation spaces contains the power generation unit and the control system, while the other installation space contains the power generation unit and the electrical connection switchgear assembly.

[0007] The aforementioned dual-power pack structure of the diesel generator set includes a control system comprising two controllers, each controller being signal-connected to one of the two generator units, which respectively control the starting, stopping, and speed regulation of the two engines and the power output of the two generators.

[0008] The aforementioned dual power pack structure for diesel generator sets, wherein each of the power generation units further includes: a cooling system; Each of the aforementioned cooling systems includes: a radiator, a cooling fan, and a coolant circulation pipe, wherein the cooling fan faces the radiator, and the radiator is connected to the cooling passages on the engine and the generator respectively via the coolant circulation pipes.

[0009] In the aforementioned dual power pack structure of the diesel generator set, each of the power generation units also includes a fuel tank, which provides fuel to the engine.

[0010] In the aforementioned dual power pack structure of the diesel generator set, two forklift slots are provided on the side of the bottom of the base frame. The base frame is equipped with multiple lifting lugs.

[0011] The aforementioned dual power pack structure for diesel generator sets includes a U-shaped base frame comprising a base frame and side frames on both sides thereof, with each generator unit disposed between the side frames. The control system, the radiator of one of the power generation units, the engine, and the generator are distributed sequentially along one of the side plates to the other. The electrical connection switchgear assembly, the radiator of the other power generation unit, the engine, and the generator are distributed sequentially along the other side plate to the first side plate; The radiator, engine, and generator of one power generation unit are arranged in a centrally symmetrical manner with the radiator, engine, and generator of another power generation unit.

[0012] In the aforementioned dual power pack structure of the diesel generator set, the cooling fan is located above the radiator and faces downwards, with one cooling fan close to one side plate and the other cooling fan close to the other side plate.

[0013] In the aforementioned dual power pack structure of the diesel generator set, the radiator of one generator unit is arranged side by side with the generator of another generator unit, the engine of one generator unit is arranged side by side with the engine of another generator unit, and the generator of one generator unit is arranged side by side with the radiator of another generator unit. The cooling fan of one of the power generation units cools the radiator of that power generation unit and the generator of another power generation unit, and the cooling fan of the other power generation unit cools the radiator of that power generation unit and the generator of another power generation unit.

[0014] Because this utility model employs the aforementioned technology, it has the following positive effects compared to existing technologies: (1) In a small data center, when the daily power load is small, one of the power generation units can be started to meet the basic power demand of the equipment, and the operating cost is low at this time. When the data center is carrying out large-scale data processing and the power load increases significantly, another power generation unit can be started quickly. The two power generation units operate at the same time to provide sufficient power for the data center. If one of the power generation units fails, such as engine failure or generator failure, the control system can automatically switch to another normally operating power generation unit to ensure that the power supply of the data center is not interrupted and to ensure the continuity and security of data processing.

[0015] (2) The power of this utility model is flexibly adjustable. According to the actual power load, it can choose to operate a single unit, reduce energy consumption and improve operating efficiency when the load is low; when the load demand is high, it can start the dual units to operate simultaneously to meet the high power demand. It improves the reliability of power supply. When one of the power generation units fails, the other power generation unit can quickly take over the entire power supply task, ensure the continuity of power supply, and reduce the losses caused by power outages.

[0016] (3) By sharing some components, this utility model effectively saves floor space and is more suitable for use in places with limited space. In addition, since the two power generation units have the same structure, it is more convenient to replace and maintain parts, reducing maintenance costs and difficulties.

[0017] (4) The two power generation units of this utility model can operate independently or work at the same time to meet different power needs. The shared heat dissipation system can effectively dissipate heat from the engines and generators of the two power generation units to ensure stable operation of the equipment. The shared base frame integrates the two power generation units together, which not only facilitates movement and installation but also reduces the floor space occupied. Attached Figure Description

[0045] In a small data center, when the daily power load is low, one of the power generation units can be started to meet the basic power needs of the equipment, resulting in low operating costs.
