Embodiment Construction
[0034] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0035] The invention provides a shutter opening and closing device for a railway generator car, which is used in the cooling system of the diesel generator set of the railway generator car.
[0036] like figure 1 and figure 2 As shown, a partition 2 is set in the compartment 1 of the generator car to separate the cooling system 3 from the generator set 4. The partition 2 separates the compartment 1 into a relatively independent engine room 5 and cooling chamber 6. The generator set 4 is installed in Inside the engine compartment 5 , the cooling system 3 is installed in a cooling chamber 6 . Each generating car is generally equipped with two sets of generator sets 4 and two sets of cooling systems 3 .
[0037] Wherein, each cooling system 3 includes a casing 7, the casing 7 is fixedly installed on the floor of the compartment 1, and a fan 53 ...

The invention relates to a shutter opening and closing device for a railway power-generation vehicle. The shutter opening and closing device comprises a top shutter component and a side shutter component and is composed of a power mechanism and a linkage mechanism, the output end of the power mechanism is connected with the linkage mechanism, and the linkage mechanism is connected with the top shutter component and the side shutter component and drives the top shutter component and the side shutter component to be in linkage rotation. The shutter opening and closing device is simple in structure, convenient to operate and reliable in control, a top air outlet and a side air outlet can be opened and closed in a linkage mode only with the power mechanism through the linkage mechanism, the control mode is simpler, cooling air inner and outer circulation is achieved, the cooling air inner circulation function is used at extremely low temperature in winter, the cooling air outer circulation function is used in the daily operation process, the problems that negative pressure in a cooling chamber of the power-generation vehicle is large in a low temperature environment in winter, and the temperature fluctuation range of cooling liquid in the daily operation process of a generator set is too wide are solved, the temperature of the cooling liquid of a diesel engine is controlled to be basically constant, the diesel engine always works in an efficient area, and the work efficiency of the generator set is improved.
Description
technical field [0001] The invention relates to a louver opening and closing device, in particular to a louver opening and closing device used in the cooling system of a diesel generator set of a railway electric car, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] During the design process of diesel generator sets and auxiliary systems for international intermodal buses passing through cold regions such as Siberia, there is a problem of how to ensure efficient and economical operation of diesel engines when diesel generator sets work in extremely low temperature environments in winter. At present, the cooling system of the railway generator car controls the water temperature of the diesel engine through a two-speed motor. Under the extremely low temperature operating environment in winter, the cooling system has a large cooling margin, the impact on the power supply of the diesel generator set when the fan is started, the water...
