Description

Technical Field

[0001] This utility model relates to the field of train turbocharger technology, and more specifically, to a water-cooled cover for a train turbocharger. Background Technology

[0002] In the railway transportation sector, the train turbocharger, as one of the core components of the power system, is crucial for ensuring the safe operation of trains due to its stable and efficient operation. To ensure that the turbocharger maintains good performance under long-term, high-intensity working conditions, effective heat dissipation measures are essential. Currently, water-cooled casings, widely used in train turbochargers, are a common heat dissipation device. This device achieves forced air cooling of the turbocharger by setting air inlets at specific locations on the casing and installing air intake fans at these inlets.

[0003] However, in practical applications, especially under the complex and ever-changing environmental conditions faced by train operation, the existing water-cooled casings have revealed significant limitations. Given the vast coverage of train routes, which traverse various geographical areas such as cities, villages, and mountains, the air quality in these areas varies significantly. In particular, the outside air usually contains a high concentration of impurities. When the intake fan introduces a large amount of impure air into the water-cooled casing, due to the lack of an effective filtration mechanism, the impurities will adhere to the surface of the turbocharger. This phenomenon not only hinders heat conduction and reduces heat dissipation efficiency, but also causes the turbocharger temperature to rise abnormally, ultimately adversely affecting its working performance and service life. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water-cooled cover for a train turbocharger, which solves the problem that the lack of a filtration mechanism in the prior art causes impurities to adhere to the surface of the turbocharger. This phenomenon not only hinders heat conduction and reduces heat dissipation efficiency, but also causes the turbocharger temperature to rise abnormally, ultimately adversely affecting its working performance and service life.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a water-cooled cover for a train turbocharger, including a water-cooled housing, with exhaust holes on both the front and rear sides of the top of the water-cooled housing, two air intake pipes fixedly installed on the lower front side of the water-cooled housing, a support frame fixedly installed on the front side of the air intake pipes, an air intake fan detachably installed on the front side of the inner wall of the air intake pipes, a filter plate inserted into the inner wall of the support frame, and a through groove opened in the lower part of the support frame.

[0006] The support frame has a sliding groove on its lower front side, a sliding plate is slidably connected to the inner wall of the sliding groove, an insert rod is fixedly installed in the middle of the sliding plate, an elastic element is sleeved on the outer side of the insert rod, and an insertion hole is opened on the lower front side of the filter plate.

[0007] The insertion rod is inserted into the lower part of the support frame, and its rear end is inserted into the inner wall of the insertion hole through the through groove. One end of the elastic element is fixedly installed between the elastic element and the slide plate, and the other end is fixedly installed between the elastic element and the inner wall of the slide groove.

[0008] The support frame has a fixed frame fixedly installed on the lower part of its inner wall. The fixed frame has a movable groove inside. A movable plate is slidably connected to the inner wall of the movable groove. Multiple elastic elements are fixedly installed on one side of the movable plate, and a cleaning brush is fixedly installed on the other side.

[0009] The front ends of multiple elastic elements are fixedly installed on the front side of the inner wall of the moving groove.

[0010] The rear part of the cleaning brush penetrates the fixing frame and is fitted with the lower front part of the filter plate.

[0011] The filter plate has a through groove at the bottom and is located in front of the intake fan.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the above solution, by installing a filter plate at the front end of the intake fan, the air flowing into the water-cooled housing can be filtered, the deposition of impurities on the surface of the turbocharger can be inhibited, and the heat dissipation efficiency can be improved. At the same time, the filter plate and the support frame adopt a plug-in assembly structure, which facilitates subsequent disassembly, maintenance and replacement operations, thereby improving the performance and operation of the water-cooled housing.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1: Please refer to Figures 1 to 8 This utility model provides a technical solution: a water-cooled cover for a train turbocharger, including a water-cooled housing 1, which is composed of an upper housing and a lower housing to facilitate the installation and disassembly of the turbocharger. Exhaust holes 2 are provided on both the front and rear sides of the top of the water-cooled housing 1. Two air inlet pipes 3 are fixedly installed on the lower front side of the water-cooled housing 1. A support frame 4 is fixedly installed on the front side of the air inlet pipes 3. An air intake fan 6 is detachably installed on the front side of the inner wall of the air inlet pipes 3. A filter plate 5 is inserted into the inner wall of the support frame 4. A through groove 13 is provided at the lower part of the support frame 4. The lower part of the filter plate 5 passes through the through groove 13 and is positioned in front of the air intake fan 6, thereby filtering the air entering the water-cooled housing 1, reducing the entry of impurities, and improving the heat dissipation effect.

[0026] The intake fan 6 is activated to dissipate heat from the supercharger inside the water-cooled housing 1, and the cooling water inside the housing circulates, thereby increasing the heat dissipation effect. Filter plates 5 are inserted into the inner wall of the support frame 4, thereby reducing the amount of impurities that enter the water-cooled housing 1 through the intake pipe 3 along with the outside air, thus improving the heat dissipation effect. When it is necessary to clean the filter plates 5, the fixing of the filter plates 5 is released, and then they can be pulled out downwards for cleaning or replacement, making it convenient for operators to use.

[0027] Example 2: Based on Example 1, in order to fix the filter plate 5, a groove 7 is provided on the lower front side of the support frame 4. A slide plate 10 is slidably connected to the rear side of the inner wall of the groove 7. An insert rod 8 is fixedly installed in the middle of the slide plate 10. An elastic element 9 is sleeved on the outer side of the insert rod 8. An insertion hole 11 is provided on the lower front side of the filter plate 5. The insert rod 8 is inserted into the lower part of the support frame 4, and its rear end is inserted into the inner wall of the insertion hole 11 through the through groove 13. One end of the elastic element 9 is fixedly installed between the slide plate 10 and the other end is fixedly installed between the inner wall of the groove 7. Thus, the elastic force of the elastic element 9 pushes the rear part of the insert rod 8 to maintain the insertion state between it and the insertion hole 11, so as to fix the filter plate 5 and the support frame 4 and facilitate maintenance and use.

[0028] When the filter plate 5 needs cleaning, pull the insert rod 8 forward, causing the slide plate 10 to move along the front side of the inner wall of the slide groove 7. This compresses the elastic element 9, causing the rear part of the insert rod 8 to disengage from the insertion hole 11. Then, pull the filter plate 5 down for cleaning or replacement. After cleaning, reset the filter plate 5 and release the insert rod 8. Use the elastic force of the elastic element 9 to push the slide plate 10 back to its original position and cause the rear part of the insert rod 8 to insert into the inner wall of the insertion hole 11, thus continuing to fix the filter plate 5 to the support frame 4, which facilitates subsequent maintenance and use.

[0029] Example 3: Based on Example 2, in order to facilitate cleaning of the filter plate 5, a fixed frame 12 is fixedly installed on the lower inner wall of the support frame 4. A movable groove 14 is opened inside the fixed frame 12. A movable plate 16 is slidably connected to the inner wall of the movable groove 14. Multiple elastic elements 15 are fixedly installed on one side of the movable plate 16, and a cleaning brush 17 is fixedly installed on the other side. The front ends of the multiple elastic elements 15 are fixedly installed on the front side of the inner wall of the movable groove 14, so that the elastic force of the elastic elements 15 keeps the cleaning brush 17 in contact with the front side of the filter plate 5. The rear part of the cleaning brush 17 penetrates through the fixed frame 12 and is in contact with the lower front side of the filter plate 5. By pulling the filter plate 5 up and down repeatedly, its front side is brought into contact with the cleaning brush 17, so that the filter plate 5 can be cleaned without the need for additional cleaning tools.

[0030] When the filter plate 5 is pulled down, multiple elastic elements 15 are installed on the inner wall of the fixed frame 12, which push the moving plate 16 to move backward along the inner wall of the moving groove 14. This causes the cleaning brush 17 to come into contact with the front side of the filter plate 5. The filter plate 5 is then pulled up and down on the inner wall of the through groove 13 to clean the surface of the filter plate 5 without the need for additional tools, making it convenient for operators and improving cleaning efficiency.

[0031] The working process of this utility model is as follows:

[0032] By activating the intake fan 6 to dissipate heat from the supercharger inside the water-cooled housing 1 and utilizing the circulating cooling water within the housing, the heat dissipation effect is enhanced. Furthermore, a filter plate 5 is inserted into the inner wall of the support frame 4, reducing the amount of impurities entering the water-cooled housing 1 with the outside air through the intake pipe 3, thus improving the heat dissipation effect. When cleaning the filter plate 5, the insert rod 8 is pulled forward, causing the sliding plate 10 to move along the front side of the inner wall of the slide groove 7. This compresses the elastic element 9, causing the rear part of the insert rod 8 to disengage from the insertion hole 11. The filter plate 5 can then be pulled downwards for cleaning or replacement. After cleaning, the filter plate 5 is reset, and the insert rod 8 is released. The elastic force of the elastic element 9 pushes the sliding plate 10 back to its original position, causing the rear part of the insert rod 8 to insert into the inner wall of the insertion hole 11, thus continuing to fix the filter plate 5 to the support frame 4, facilitating subsequent maintenance.

[0033] When the filter plate 5 is pulled down, multiple elastic elements 15 are installed on the inner wall of the fixed frame 12, which push the moving plate 16 to move backward along the inner wall of the moving groove 14. This causes the cleaning brush 17 to come into contact with the front side of the filter plate 5. The filter plate 5 is then pulled up and down on the inner wall of the through groove 13 to clean the surface of the filter plate 5 without the need for additional tools, making it convenient for operators and improving cleaning efficiency.
