Description

Technical Field

[0001] The present invention relates to the technical field of electrical rooms, and specifically to a ventilation structure for an integral cabinet-type electrical room of an outside corridor shunting locomotive. Background Art

[0002] The integral cabinet-type design of the electrical room is an important part of the overall vehicle modular design. The electrical components in the electrical room are the basic components of the locomotive electric drive system, and have the functions of converting electrical energy, controlling, regulating and protecting the locomotive. The structure of the electrical room directly affects the operability and maintainability of the electrical components, and thus affects the performance of the entire locomotive. The structural layout of the electrical room should not only meet the indicators such as mechanical strength, stiffness and vibration, but also meet the ventilation and heat dissipation conditions required by the electrical components, and should have the functions of waterproofing and dustproofing. Therefore, the structural design of the electrical room is crucial for ensuring the overall quality level.

[0003] Currently, for the ventilation structure of the existing electrical room, the electrical components are installed in the upper part of the electrical room, and the air outside the vehicle enters from one side through the filter window installed on the side wall and is discharged from the other side. During the operation of the locomotive, when passing by the air outlet side, the discharged hot air will reduce the comfort of the crew, and may even cause harm to the personnel. It cannot protect against high humidity and foggy water vapor. Since there is no independent air duct, the humid air, dust, etc. entering the interior of the electrical room will adhere to the electrical components, causing harm to the electrical components for a long time. When entering from the lower part and being discharged through the air duct and the ventilator, the ventilation efficiency is affected. The filter screen needs to be disassembled for cleaning. The air duct at the air inlet is arranged on the upper part of the steel structure of the electrical room and is a welded structure, and it is inconvenient to repair problems such as rust inside.

[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a ventilation structure for an integral cabinet-type electrical room of an outside corridor shunting locomotive. Summary of the Invention

[0005] The purpose of the present invention is to provide a ventilation structure for an integral cabinet-type electrical room of an outside corridor shunting locomotive to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: An overall cabinet-type electrical room ventilation structure for a corridor shunting locomotive, including an electrical room. Above the interior of the electrical room, there is a main inverter module mounting seat. On the main inverter module mounting seat, there is a main inverter module. Below the main inverter module, there is a main inverter module air duct. On the side of the electrical room, there is an electrical component mounting seat. On the electrical component mounting seat, there are electrical components. Between the main inverter module mounting seat and the electrical component mounting seat and the electrical room, there are respectively separated electrical compartments and ventilation compartments. In the ventilation compartment, there is a ventilator. In the electrical compartment, there is an electrical room air duct. Between the electrical room air duct and the electrical room, there is an air inlet assembly. The electrical room air duct is connected to the ventilator. Below the air inlet assembly, there is a maintenance door on the outer wall of the electrical room.

[0007] Preferably, a waterproof louver is provided on the outer wall of the ventilation compartment opposite to the electrical room.

[0008] Preferably, the air inlet assembly is composed of a filter window, a gasket, and an air inlet air duct. The filter window is composed of a stainless steel filter screen and a filter frame. The stainless steel filter screen is located on the outside, and the filter window frame is located on the inside and is in an "L" shape. The blades are in a "Y" shape profile.

[0009] Preferably, there are four air inlet air ducts, and they are arranged in pairs opposite to each other. The adjacent air inlets are independently arranged, and the ventilation areas of adjacent two air inlet devices are different.

[0010] Preferably, the filter window, the gasket, and the air inlet air duct are all detachably connected to each other.

[0011] Preferably, the air inlet air duct has a slope structure and is 155 mm away from the filter window, and the slope is a 30° structure.

[0012] Preferably, at the lower end of the mounting surface of the filter window, there is a drain hole with a length of 120 mm and a height of 15 mm to ensure the smooth discharge of rainwater.

[0013] Preferably, the periphery of the air inlet air duct all has a slope structure.

[0014] Preferably, there is a flow deflector in the electrical room air duct, and the flow deflector is used to reduce wind resistance.

[0015] Preferably, the bottom housing of the ventilator is provided with air outlets in a relative shape.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The present invention relates to a ventilation structure for the integral cabinet-type electrical chamber of an outside corridor shunting locomotive. After the air outside the vehicle enters, the main inverter module takes away the heat, and the electrical chamber air duct cools the electrical components installed at the air duct, and then, via the ventilator, it is discharged to the underframe traction motor air duct, and is discharged out of the vehicle through the path of discharging from the lower row and the side, so as to cool the traction motor, and finally discharge the hot air out of the vehicle to avoid harm to personnel caused by the discharged hot air; the entire electrical chamber air duct is an independent structure, and the humid air, dust, etc. entering the inside of the air duct only adhere to the inside of the air duct and will not harm the electrical components; various flow guiding plates are arranged inside the entire electrical chamber air duct structure to reduce the wind resistance; a water receiving tank is arranged at the lower part of the underframe traction motor air duct, and the water inside the entire air duct can be discharged through the drain pipe to prevent the internal water from affecting the traction motor. This solution designs a dedicated ventilation air duct, rationally utilizes the space structure, plans the optimal ventilation path, ensures sufficient air volume, and improves the heat dissipation efficiency.

[0018] The present invention relates to a ventilation structure for the integral cabinet-type electrical chamber of an outside corridor shunting locomotive. The filter window is composed of two parts. The outermost side is a stainless steel filter screen, which mainly prevents catkins and large-particle dust from entering. This filter screen can be externally cleaned of catkins without disassembly; the inner filter window frame is overall in an "L" shape, and the blades are in a "Y" - shaped profile. This structure can effectively prevent 99% of rainwater from invading. The four upper air inlet devices are independent modules and have no influence on each other. The ventilation areas of two adjacent air inlet devices are different and are designed according to their respective air usage requirements to achieve on-demand distribution. The air inlet device can be disassembled as a whole, and after disassembly, the main inverter module can be overhauled and maintained. This solution can ensure the air cleanliness in the electrical chamber, designs an effective drainage path, and maximally protects the internal components of the electrical chamber.

[0019] The present invention relates to a ventilation structure for the integral cabinet-type electrical chamber of an outside corridor shunting locomotive. The periphery of the air inlet air duct adopts a slope structure. This structure can not only prevent water and drain water, but also play a guiding role in the air while increasing the ventilation volume, and reduce the wind resistance.

[0033] AsFigure 7 As shown, the air inlet component 7 is composed of a filter window 12, a gasket 13, and an air inlet duct 14. The filter window 12 is composed of a stainless steel filter screen and a filter frame. The stainless steel filter screen is located on the outside, and the filter window frame is located on the inside and is in an "L" shape. The blades are in a "Y" - shaped profile.
