[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Please refer to Figures 1 to 5 A railway locomotive air conditioning unit, including shell 1, be equipped with two equipment installation cavities 101 in shell 1, be equipped with partition 2 between two equipment installation cavities 101, partition 2 is fixedly connected with the inner wall of shell 1, the opening of two equipment installation cavities 101 is connected with open and close cover plate 3, ventilation hole 301 is formed in the side wall of two open and close cover plates 3.

[0023] As Figures 1 to 5 Indicated, the railway locomotive air conditioning unit in the utility model is similar to the structure of the prior art railway locomotive air conditioning unit, such as the railway locomotive air conditioning unit disclosed in the patent with the publication number CN222022697U, the main improvement point of the utility model is that the operation stability of the air conditioning unit is guaranteed, and the maintenance operation process is simplified, as Figures 1 to 5 Indicated, when the equipment in any equipment installation cavity 101 in shell 1 needs to be overhauled and maintained, only the open and close cover plate 3 at the corresponding position needs to be opened in the railway locomotive air conditioning unit in the utility model during use, so that the equipment installation cavity 101 is exposed, the equipment in the cavity is maintained or overhauled, and the equipment on the other side can still be safely closed in the equipment installation cavity 101, effectively preventing foreign matters from invading, guaranteeing the operation stability of the air conditioning unit, and simplifying the maintenance operation process, wherein the partition 2 is used to separate the two equipment installation cavities 101, if the connecting wires of the equipment in the two equipment installation cavities 101 need to be connected with each other, then the side of the partition 2 can be punched, so that the connecting wires can be connected with each other by punching, and the ventilation hole 301 on the side of the open and close cover plate 3 can be used with metal mesh, which can block foreign matters, dust and the like from entering the equipment installation cavity 101 while guaranteeing the ventilation and heat dissipation of the internal equipment.

[0024] As shown in Figures 1 to 5 , the upper and lower ends of the shell 1 near the partition 2 are fixedly connected with the fixed seats 4, the upper and lower sides of the adjacent end of the two openable and closable cover plates 3 are rotatably connected with the two fixed seats 4 through the rotating shafts, and the sides away from each other of the two openable and closable cover plates 3 are connected with the cover sealing assemblies, respectively. The two openable and closable cover plates 3 are flipped through the fixed seats 4 at the same time, and two sets of connecting pieces of the openable and closable cover plates 3 do not need to be installed on the shell 1, so that the processing efficiency of the shell 1 is improved, and the manufacturing cost of the shell 1 is reduced.

[0025] As shown in Figures 1 to 5 , the cover sealing assembly comprises a plurality of fixed blocks 5 and a plurality of fastening blocks 6, the plurality of fastening blocks 6 are fixedly connected with the side away from the fixed seat 4 of the openable and closable cover plate 3, and the plurality of fixed blocks 5 are fixedly connected with the side wall of the shell 1 near the end of the fastening block 6. The threaded rod of the bolt is threadedly connected with the adjacent fixed block 5 after penetrating through the fastening block 6. When the openable and closable cover plate 3 is covered on the shell 1 and the equipment installation cavity 101 is closed, the fastening block 6 is tightened on the fixed block 5 by using the bolt, so that the installation and fixation of the openable and closable cover plate 3 and the shell 1 are realized, and the sealing effect of the openable and closable cover plate 3 on the equipment installation cavity 101 is ensured by using the bolt.

[0026] As shown in Figures 2 to 4 , the end of the openable and closable cover plate 3 near the fixed seat 4 and the side near the equipment installation cavity 101 is fixedly connected with the sealing strip 7, and the sealing strip 7 abuts against the partition 2. The end of the openable and closable cover plate 3 rotatably connected with the fixed seat 4 has a larger gap between the shell 1 and the partition 2 due to the flipping. The gap between the openable and closable cover plate 3 and the partition 2 is filled and closed by the extrusion between the sealing strip 7 and the partition 2 when the openable and closable cover plate 3 is covered outside the equipment installation cavity 101, so that the sealing effect of the equipment installation cavity 101 is improved.

[0027] As shown in Figures 2 to 4 , the side of the openable and closable cover plate 3 near the equipment installation cavity 101 is connected with the cover plate sealing strip 8, the cover plate sealing strip 8 has a U-shaped structure, and the other side of the cover plate sealing strip 8 abuts against the opening edge of the shell 1. When the openable and closable cover plate 3 is covered at the opening of the equipment installation cavity 101, the gap between the openable and closable cover plate 3 and the shell 1 is filled by the contact between the cover plate sealing strip 8 and the edge of the shell 1, so that the closing effect between the openable and closable cover plate 3 and the shell 1 is further improved, wherein the cover plate sealing strip 8 can be made of sponge, silica gel or other compressible materials.

[0028] As shown in Figures 2 to 4As shown, the housing 1 opening edge is fixedly connected with a U-shaped convex strip 9, and the cover plate sealing strip 8 is abutted with the U-shaped convex strip 9. When the cover plate 3 is covered on the equipment installation cavity 101, the cover plate sealing strip 8 is abutted on the housing 1 edge, and the U-shaped convex strip 9 is extruded in the cover plate sealing strip 8, and the mutual cooperation makes the sealing effect between the cover plate 3 and the housing 1 better.

[0029] As shown in the drawings, Figures 1 to 5 The cover plate sealing strip 8 is inlaid in the side wall of the cover plate 3, and the cover plate sealing strip 8 covers the U-shaped convex strip 9. Inlaid the cover plate sealing strip 8 in the side wall of the cover plate 3, can avoid the cover plate sealing strip 8 being scratched and damaged in the process of opening the cover plate 3 for inspection and maintenance, and cooperate with the U-shaped convex strip to ensure the sealing effect of the cover plate 3 on the equipment installation cavity 101.

[0030] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model.
