Description

Technical Field

[0001] The utility model relates to an air-conditioning system of an urban rail transit vehicle, in particular to a condensation drainage interface structure that satisfies the requirement of rapid disassembly and assembly of an air-conditioning unit. Background Art

[0002] Most of the drainage methods of embedded air-conditioning units in the roof-mounted units of urban rail transit adopt centralized drainage through pipes. The interface between the drainage pipe and the air-conditioning unit is mainly a threaded structure with sealing tape for sealing connection. When the air-conditioning unit needs to be replaced quickly, it is limited by the threaded interface structure of the drainage pipe and the maintenance space. The disassembly and assembly time is long and the process is complicated. In addition, an inspection door needs to be added to the roof panel of the car, which affects the overall layout of the interior. In order to meet the needs of rapid disassembly and assembly of the air-conditioning unit, a condensation drainage interface structure that meets the needs of rapid disassembly and assembly of the air-conditioning unit needs to be designed. Utility Model Content

[0003] The utility model aims to design a condensation drainage interface structure that satisfies the requirement of rapid disassembly and assembly of an air-conditioning unit, so as to facilitate replacement of the air-conditioning unit, save time and labor costs, and ensure the integrity of the roof layout in the vehicle.

[0004] To achieve the above-mentioned purpose, the utility model provides a condensation drainage interface structure that meets the requirements of quick disassembly and assembly of the air-conditioning unit, including a drainage circular pipe, a circular sealing cotton and a water receiving box structure. The drainage circular pipe is located on the side of the air-conditioning unit, and the circular sealing cotton is pasted around the condensation drainage circular pipe. A water receiving box structure is arranged at a position corresponding to the drainage circular pipe above the roof plate in the vehicle. The water receiving box structure includes a flange structure and a water receiving box body. The flange structure is located on the side of the roof plate in the vehicle. The flange structure is fixed at the top opening of the water receiving box body by bolts. The flange structure is circular and has bosses around it. The circular sealing cotton on the side of the air-conditioning unit is pressed on the bosses of the flange structure to ensure that the interface is sealed and leak-proof. The condensed water generated by the air-conditioning unit enters the water receiving box body through the drainage circular pipe. The water pipes are welded to the bottom of the end surface of the water receiving box body to effectively discharge the water stored in the box.

[0005] Furthermore, a rubber sealing gasket is provided between the flange structure and the water receiving box body.

[0006] Furthermore, the water receiving box body is in the shape of a flat rectangular parallelepiped and is made of stainless steel.

[0007] Furthermore, the flange structure is made of stainless steel.

[0008] Furthermore, the inner diameter of the flange structure and the top opening diameter of the water receiving box body are both larger than the outer diameter of the drainage circular pipe.

[0009] Furthermore, the inner diameter of the circular sealing cotton is larger than the outer diameter of the circular drainage pipe, and the outer diameter of the circular sealing cotton is larger than the outer diameter of the flange surface of the flange structure.

[0010] The existing air-conditioning unit condensation drainage structure is usually sealed and fastened with a threaded structure. The installation and disassembly of the air-conditioning unit must be time-consuming and requires corresponding procedures. The present structure can realize the rapid disassembly and assembly of the air-conditioning unit, reduce the steps of the air-conditioning unit disassembly and assembly process, save time and labor costs, and there is no need to open an inspection door on the roof of the vehicle to ensure the aesthetic requirements of the integrated layout of the roof.

[0017] A condensation drainage interface structure suitable for narrow spaces and without disassembly and assembly procedures is designed. The condensation drainage interface structure includes two parts: a drainage circular pipe 1 and a circular sealing cotton 2 on the air conditioning unit side, and a water receiving box structure on the roof side of the vehicle. The water receiving box structure includes a circular flange structure 3 with a boss and a water receiving box body 4. A waterproof circular sealing cotton 2 is pasted around the condensation drainage circular pipe 1 at the bottom of the air conditioning unit. Figure 1 and Figure 2 shown.

[0018] A circular flange structure 3 with a boss and a water receiving box body 4 are arranged above the roof of the vehicle at a position corresponding to the circular drainage pipe 1. The top of the water receiving box body 4 is opened and the flange structure 3 is fixed with bolts. To ensure the seal between the flange structure 3 and the water receiving box body 4, a circular flange rubber gasket is sandwiched in the middle. Figure 2 and Figure 3 shown.

[0019] The circular sealing cotton 2 on the air-conditioning unit side is pressed on the boss of the flange structure 3 to ensure that the interface is sealed and leak-proof. There is no mechanical connection structure between the interfaces, which facilitates the rapid disassembly of the air-conditioning unit. There is no need to open an inspection door on the roof panel in the car to ensure the aesthetic requirements of the integrated roof panel layout.

[0020] The condensation drainage interface has the following structural form and characteristics: the flange structure 3 and the water receiving box body 4 are made of stainless steel metal, which can effectively resist corrosion and oxidation; the water receiving box body 4 adopts a flat rectangular shape, has the ability to store condensed water and is suitable for narrow space environments; the water pipe 5 welded at the lowest point of the end face of the water receiving box body 4 is conducive to discharging the water stored in the box; the inner circle diameter of the flange structure 3 and the diameter of the top opening of the water receiving box body 4 are both larger than the outer diameter of the drainage circular pipe 1, and the contactless redundant setting can ensure that the installation deviation does not affect the disassembly and assembly of the air-conditioning unit; the inner diameter of the circular sealing cotton 2 is larger than the outer diameter of the drainage circular pipe 1 and the outer diameter of the circular sealing cotton 2 is larger than the outer diameter of the flange surface of the flange structure 3, and the redundant setting can ensure that the installation deviation does not affect the interface crimping seal.

[0021] The condensation drainage interface structure is mainly composed of a condensation drainage round pipe 1, a waterproof round sealing cotton 2, a round boss flange structure 3, and a water receiving box body 4. After the air-conditioning unit is installed, the round sealing cotton 2 of the air-conditioning unit is pressed on the boss of the round boss flange structure 3 to generate compression to ensure the interface sealing ( Figure 3 ), the condensed water generated by the air conditioning unit enters the water receiving box body 4 through the drainage circular pipe 1 and is discharged through the water pipe on the end surface of the water receiving box.
