Description

Technical Field

[0001] This utility model relates to the field of rail transit air conditioning technology, and in particular to a backup air supply device for the driver's cab of rail transit air conditioning. Background Technology

[0002] Currently, the driver's cab of high-speed trains uses a separate air conditioning unit for air conditioning. In the event of a malfunction or maintenance of the driver's cab air conditioning unit, a backup fan can be immediately put into use to ensure continuous ventilation in the driver's cab and protect the driver's working environment and safety. However, the addition of a backup fan mainly affects the complexity of the structure and piping layout within the limited space at the top of the carriage. In addition, it will also lead to increased manufacturing and assembly costs due to the needs of the transition period.

[0003] Therefore, a backup air supply device for the driver's cab of rail transit is still needed to solve the above problems. Utility Model Content

[0004] This utility model provides a backup air supply device for the driver's cab of rail transit air conditioning to solve the above-mentioned problems.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A backup air supply device for a rail transit air conditioning driver's cab includes:

[0007] The air duct body is provided with spaced warm air ducts and cold air ducts, which are used to separate the cold air and warm air output from the air conditioning unit and enter the carriage respectively.

[0008] Connecting pipe;

[0009] A blower assembly, wherein the air inlet of the blower assembly is connected to the side wall of the air duct body via a connecting pipe, and the blower assembly is used to blow the gas drawn into the air duct body through the air inlet to the cab through the air outlet.

[0010] In one embodiment, the blowing assembly includes an adapter tube, a blowing module, and a connecting frame. The air inlet is opened on the side wall of the adapter tube, and the interior of the adapter tube has a through-hole air chamber. The blowing module is connected to one end of the adapter tube through the connecting frame to form a negative pressure in the air inlet, pumping the gas in the air duct body at the other end of the connecting tube into the air and finally outputting it through the air chamber.

[0011] In one embodiment, the blower module includes a motor and fan blades connected to a rotating shaft, the outer wall of the motor is fixedly connected to the connecting frame, and the outer wall of the adapter cylinder is also connected to a connector for electrically connecting the motor.

[0012] In one embodiment, the other end of the adapter tube opposite the blowing module is connected to a transmission pipe, through which airflow is directionally delivered to the cab.

[0013] In one embodiment, a clamp is fitted onto the outer side of the connecting pipe, and an extension pipe is formed on the outer wall of both the air duct body and the adapter tube. The clamp binds the end of the connecting pipe to the outer wall of the extension pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0015] By connecting the air duct body with the air blowing component, the air duct body is divided into warm air ducts and cold air ducts. Under different modes, under the negative pressure formed by the air blowing component, warm and cold air can quickly and easily enter the driver's cab. There is no need to set up additional and independent cooling or heating equipment to blow air into the driver's cab separately, which reduces costs and simplifies the layout and design of the air conditioning unit on the top of the carriage.

[0021] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0022] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0023] Reference Figure 1-4 This utility model provides a backup air supply device for the driver's cab of a rail transit air conditioning system, comprising:

[0024] The air duct body 1 is provided with spaced warm air ducts 11 and cold air ducts 12. The warm air ducts 11 and cold air ducts 12 are used to separate the cold air and warm air output from the air conditioning unit and allow them to enter the passenger compartment respectively. The air duct body 1 is connected to the top of the passenger compartment, and the air conditioning unit is connected to a position close to the air duct body 1. The cooling or heating pipes of the air conditioning unit are connected to the warm air ducts 11 and cold air ducts 12 through a T-junction pipe, and the airflow path is switched during cooling and heating through a split valve. It should be noted that at the same time, only one flow path of the warm air duct 11 and the cold air duct 12 is in operation.

[0025] The air blowing assembly 3 has its air inlet connected to the side wall of the air duct body 1 via a connecting pipe 2. The air blowing assembly 3 is used to blow the gas drawn into the air duct body 1 through the air inlet towards the driver's cab through the air outlet. The air blowing assembly 3 can be connected near the driver's cab or to the top of the vehicle compartment; there is no limitation on this. The air blowing direction of the air blowing assembly 3 intersects with the airflow direction of the connecting pipe 2, thereby creating a negative pressure during operation. This diverts some of the gas from the air conditioning unit supplying hot or cold air to the driver's cab, eliminating the need for a separate air conditioning unit. This temporarily meets the air supply needs of the driver's cab during malfunctions or maintenance, reducing resource waste and simplifying the design of the roof space.

[0026] Preferably, the air blowing assembly 3 includes an adapter cylinder 31, an air blowing module 32, and a connecting frame 33. The air inlet is located on the side wall of the adapter cylinder 31, and the interior of the adapter cylinder 31 has an air cavity extending through both ends. The air blowing module 32 is connected to one end of the adapter cylinder 31 via the connecting frame 33, and is used to create a negative pressure in the air inlet to pump the gas in the air duct body 1 at the other end of the connecting pipe 2 into the air duct and finally output it through the air cavity. The adapter cylinder 31 can be, for example, a columnar structure with open ends. The main function of the air blowing module 32 is to create a negative pressure at the side opening of the connecting pipe 2, and to pump part of the airflow in the air duct body 1 into the cab through the negative pressure. This simple structure achieves the diversion of some of the gas in the vehicle compartment to supply the cab, simplifying the design and reducing the difficulty of arranging the air conditioner on the top.

[0027] Preferably, the blower module 32 includes a motor 321 and a fan blade 322 connected to a rotating shaft. The outer wall of the motor 321 is fixedly connected to the connecting frame 33, and the outer wall of the adapter cylinder 31 is also connected to a connector 34 for electrically connecting the motor 321. The bottom of the connecting frame 33 has a gap, allowing airflow to enter the motor 321 after it is fixed. The adapter cylinder 31 has three openings; the opening connected to the connecting pipe 2 is located on one side and forms a perpendicular angle with the airflow blown out by the fan blade 322, thereby stably pumping airflow from the vehicle compartment into the driver's cab. The connector 34, for example, is an electrical adapter plug, serving as an electrical connection.

[0028] Preferably, the other end of the adapter tube 31 opposite the air blowing module is connected to a transmission pipe, through which airflow is directionally delivered to the cab. The transmission pipe allows for more specific airflow to be directed to more specific locations within the cab, meeting a wider range of needs.

[0029] Preferably, a clamp 21 is fitted onto the outer side of the connecting pipe 2, and an extension pipe 4 is formed on the outer wall of both the air duct body 1 and the adapter cylinder 31. The clamp 21 binds the end of the connecting pipe 2 to the outer wall of the extension pipe 4. The clamp 21 can seal the connection at the end of the connecting pipe 2, prevent airflow leakage, and ensure stable delivery.

[0030] Preferably, the warm air duct 11 is arranged on both sides of the cold air duct 12. An opening is formed in the partition 5 between the warm air duct 11 and the cold air duct 12. An air baffle is arranged inside the warm air duct 11 near the opening. The sidewall of the air baffle divides the opening on the inner side of the duct body 1 corresponding to the air outlet into two areas. The air baffle between the cold air duct 12 and the warm air duct 11 prevents internal airflow from forming turbulence when the airflow inside the duct body 1 is delivered to the driver's cab. Dividing the opening effectively avoids this situation. Additionally, it should be noted that air vents facing the driver's cab are respectively formed on the duct body 1 at the locations corresponding to the warm air duct 11 and the cold air duct 12.

[0031] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
