Description

Technical Field

[0001] The invention belongs to the technical field of generators, and in particular relates to a container-type diesel generator set. Background Art

[0002] A containerized diesel generator set is a power generation device that integrates a diesel generator set, fuel tank, control system and auxiliary equipment in a standard container. This design is not only convenient for transportation and installation, but also effectively protects the generator set from environmental impacts and extends its service life. Containerized generator sets are widely used in engineering construction, emergency power supply, mobile power supply and other scenarios, with good mobility and flexibility. Its power system is usually composed of an efficient diesel engine and generator, and can operate stably under various load conditions. Compared with traditional power generation methods, containerized diesel generator sets have higher fuel economy and lower maintenance costs, and are very suitable for use in scenarios where there is a lack of electricity or temporary electricity demand.

[0003] However, due to the limited internal space and poor air circulation of containerized diesel generator sets, when the generator runs at high load for a long time, the heat is difficult to be discharged naturally, resulting in high temperature and equipment failure. At the same time, since the diesel engine will produce a lot of noise during operation, the sealing and sound insulation of the container are also issues that need to be considered. However, heat dissipation and sealing and sound insulation cannot be effectively taken into account at the same time, which leads to the use defects of containerized diesel generator sets. Improvements are needed to address the above problems. Summary of the invention

[0005] Preferably, the surface of the exhaust pipe located outside the container body is installed with sound insulation cotton, and the surface of the exhaust pipe located outside the container body is a continuous S-shaped structure, an exhaust fan is installed at one end of the exhaust pipe located outside the container body, the exhaust fan is a high temperature resistant exhaust fan, and a vent is opened at the exhaust port of the diesel engine, so that the exhaust gas and noise generated by the diesel engine can be effectively discharged and silenced.

[0006] Preferably, a connecting door is installed in the middle of the partition plate, and heat insulation cotton is installed on the side of the connecting door close to the power generation room, so as to facilitate walking between the power generation room and the transmission room and prevent the temperature of the power generation room from affecting the transmission room.

[0007] Preferably, thermal insulation cotton is installed on the surface of the cooling water tank, and the cold end of the semiconductor refrigerator A is attached to the surface of the cooling water tank to absorb heat.

[0008] Preferably, a water pipe is connected between the upper portion of one end of the cooling water tank and the output end of the water pump, and the water pipe is a continuous S-shaped structure, which is conducive to the heat dissipation and cooling of the cooling water after absorbing heat.

[0009] Preferably, an auxiliary refrigeration pipe is fixedly installed at the bottom of the other end of the cooling water tank, and thermal insulation cotton is installed on the surface of the auxiliary refrigeration pipe. A semiconductor refrigerator B is installed at equal distances on the surface of the auxiliary refrigeration pipe. The cold end of the semiconductor refrigerator B is attached to the surface of the auxiliary refrigeration pipe for absorbing heat. The auxiliary refrigeration pipe is a continuous S-shaped structure, which is conducive to cooling the cooling water again. A delivery pipe is connected between the bottom of the auxiliary refrigeration pipe near one end of the cooling water tank and the spiral liquid cooling pipe, so that the diesel engine and the generator can be effectively cooled and heat absorbed.

[0010] Preferably, thermal insulation cotton is installed on the surface of the air inlet pipe, the air inlet pipe is a continuous S-shaped structure, and semiconductor refrigerators C are installed at equal distances on the surface of the air inlet pipe. The cold end of the semiconductor refrigerator C is attached to the surface of the air inlet pipe to absorb heat and cool the incoming air.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) This container-type diesel generator set has an effective cooling and soundproof exhaust structure. The cooling structure combined with water cooling and air cooling can effectively cool the diesel engine, ensuring that the temperature generated by the long-term high-load operation of the diesel engine will not cause the failure of the diesel engine. At the same time, the effective closed sound insulation and exhaust structure can prevent the noise of the diesel engine from affecting the surroundings, thereby effectively improving the performance of the container-type diesel generator set. At the same time, this container-type diesel generator set has a simple structural design, is easy to use, stable and reliable, and its performance can meet the use requirements; (2) When the diesel engine is started, the generator is driven by the transmission shaft to start generating electricity. The diesel engine needs oxygen to start. The external oxygen is transported to the generator room through the intake pipe for the diesel engine to start. At the same time, the diesel engine and the generator will generate noise. At this time, the noise generated by the diesel engine and the generator is reduced by the sound insulation cotton to avoid noise pollution. When the diesel engine is started, the exhaust fan is turned on at the same time, so that the exhaust fan discharges the exhaust gas through the vent and the exhaust pipe of the continuous S-shaped structure. The air and heat inside the generator room can be extracted through the vent to achieve the purpose of heat dissipation. At the same time, the vent is conducive to the formation of negative pressure inside the exhaust pipe of the continuous S-shaped structure, which is conducive to exhaust. At the same time, the noise generated by the exhaust of the diesel engine will be reduced by the long-distance transmission of the exhaust pipe of the continuous S-shaped structure to avoid noise pollution. (3) Before the diesel engine and generator are used, the semiconductor refrigerator A and the semiconductor refrigerator B are started to cool the cooling water in the cooling water tank and the auxiliary cooling pipe. When the diesel engine and the generator are started, the water pump is turned on to circulate the cooling water tank, the auxiliary cooling pipe, the delivery pipe, the spiral liquid cooling pipe and the water delivery pipe. At the same time, the cooling water is cooled by the semiconductor refrigerator A and the semiconductor refrigerator B. When the cooled cooling water is transported inside the spiral liquid cooling pipe, it can continuously and effectively absorb heat and cool the diesel engine and the generator, which is beneficial to reduce the temperature of the diesel engine and the generator and ensure their stable operation. (4) When semiconductor refrigerator A and semiconductor refrigerator B are started to cool the cooling water in the cooling water tank and the auxiliary cooling pipe, the blower and semiconductor refrigerator C are turned on simultaneously. The blower will transport the external air to the inside of the ventilation pipe through the air intake pipe, and then the air will be transported to the inside of the power generation room. When semiconductor refrigerator C is turned on, the flowing air will be cooled and cooled inside the air intake pipe. The cooled air can absorb the heat of the transmission room through the ventilation pipe to cool the transmission room. At the same time, the cooled air will be transported to the inside of the power generation room, thereby cooling the inside of the power generation room. After that, when the diesel engine and generator are started and used, the diesel engine and generator can be effectively cooled by absorbing heat, which effectively ensures the stable operation of the diesel engine and generator.

At the same time, the effective closed sound insulation and exhaust structure can prevent the noise of the diesel engine from affecting the surrounding area, thereby effectively improving the performance of the containerized diesel generator set. At the same time, this containerized diesel generator set has a simple structural design, is easy to use, stable and reliable, and its performance can meet the use requirements.

[0019] The surface of the exhaust pipe 7 located outside the container body 1 is installed with sound insulation cotton, and the surface of the exhaust pipe 7 located outside the container body 1 is a continuous S-shaped structure.

[0020] Specifically, when the diesel engine 2 is started, the generator 3 is driven by the transmission shaft to start generating electricity. The diesel engine 2 needs oxygen to start. The external oxygen is transported to the generator room through the intake pipe 14 for use in starting the diesel engine 2.

When the diesel engine 2 is started, the exhaust fan 17 is turned on at the same time, so that the exhaust fan 17 discharges the exhaust gas through the vent 16 and the exhaust pipe 7 with a continuous S-shaped structure. The air and heat inside the power generation room can be extracted through the vent 16 to achieve the purpose of heat dissipation. At the same time, the vent 16 is conducive to the formation of negative pressure inside the exhaust pipe 7 with a continuous S-shaped structure, which is conducive to exhaust. At the same time, the noise generated by the exhaust gas of the diesel engine 2 will be reduced through the long-distance transportation of the exhaust pipe 7 with a continuous S-shaped structure to avoid noise pollution.

Semiconductor refrigerators B20 are installed at equal distances on the surface of the auxiliary refrigeration pipe 12. The cold end of the semiconductor refrigerator B20 is attached to the surface of the auxiliary refrigeration pipe 12 to absorb heat. The auxiliary refrigeration pipe 12 is a continuous S-shaped structure, which is conducive to cooling the cooling water again. A delivery pipe 13 is connected between the bottom of the auxiliary refrigeration pipe 12 near one end of the cooling water tank 9 and the spiral liquid cooling pipe 8, so that the diesel engine 2 and the generator 3 can be effectively absorbed and cooled.

[0022] Specifically, before the diesel engine 2 and the generator 3 are used, the semiconductor refrigerator A11 and the semiconductor refrigerator B20 are started first to cool the cooling water inside the cooling water tank 9 and the auxiliary cooling pipe 12. When the diesel engine 2 and the generator 3 are started, the water pump 10 is turned on to circulate the cooling water tank 9, the auxiliary cooling pipe 12, the delivery pipe 13, the spiral liquid cooling pipe 8 and the water delivery pipe 19.

[0024] Specifically, when the semiconductor refrigerator A11 and the semiconductor refrigerator B20 are started to cool the cooling water in the cooling water tank 9 and the auxiliary cooling pipe 12, the blower 18 and the semiconductor refrigerator C21 are started synchronously. The opening of the blower 18 will transport the external air to the inside of the ventilation pipe 15 through the air inlet pipe 14, and then the air is transported to the inside of the power generation room, and the opening of the semiconductor refrigerator C21 will cause the flowing air to be cooled in the inside of the air inlet pipe 14. The cooled air can absorb the heat of the power transmission room through the ventilation pipe 15 to cool the power transmission room, and at the same time, the cooled air will be transported to the inside of the power generation room, thereby cooling the inside of the power generation room; Afterwards, when the diesel engine 2 and the generator 3 are started and used, the diesel engine 2 and the generator 3 can be effectively cooled by absorbing heat, thereby effectively ensuring the stable operation of the diesel engine 2 and the generator 3.
