[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Existing technologies for purifying and filtering lubricating oil present several drawbacks. Firstly, it's inconvenient to disassemble, replace, and clean the filter structure, thus hindering continuous filtration. Secondly, during replacement and cleaning, maintaining the oil passage's seal is difficult, allowing external dust and impurities to enter and cause unnecessary contamination. Please refer to [the relevant documentation / reference needed]. Figures 1-4The embodiment provides a wheelset axle box lubrication structure with oil circulation and purification, which can effectively improve the efficiency of disassembling and cleaning the purification structure, while preventing external dust from contaminating the oil circuit during disassembly and cleaning. The wheelset axle box lubrication structure with oil circulation and purification includes an oil reservoir 1, a purification device installed on the right side of the oil reservoir 1, a cooling device installed at the bottom of the oil reservoir 1, and a conveying connection device connected to the bottom left side of the oil reservoir 1.

[0023] The purification device includes a purification structure and a sealing structure, with the sealing structure installed on top of the purification structure. The purification structure includes a purification chamber 101, inside which a slot 102 is installed. A filter plate 103 is connected inside the slot 102, and a pull ring 104 is installed in the center of the top surface of the filter plate 103. The sealing structure includes a sealing plate 105, with a rotating shaft 106 fixedly connected to one end of the front and back of the sealing plate 105. A fixing block 107 is connected to the outer surface of the rotating shaft 106, and a torsion spring 108 is connected to the side of the fixing block 107 away from the rotating shaft 106.

[0024] The slot 102 is fixedly connected to the inner wall of the purification box 101. The front and back of the filter plate 103 are sealed and slidably connected to the inner wall of the slot 102 with a convex groove in the middle. The outer surface of the filter plate 103 is sealed and slidably connected to the top surface of the purification box 101 with a through hole. The bottom of the fixing block 107 is fixedly connected to the top surface of the purification box 101. The end of the torsion spring 108 away from the fixing block 107 is fixedly connected to the end of the rotating shaft 106 away from the sealing plate 105.

[0025] By using the filter plate 103 and the slot 102 to engage with the purification device, it is easy to replace and clean the filter plate 103. At the same time, the installation of the sealing plate 105 makes it easy to seal the disassembly point during the disassembly and replacement process.

[0026] When disassembling and cleaning the lubricating oil purification structure, the filter plate 103 and the slot 102 are engaged by a convex groove, which facilitates the quick disassembly and cleaning of the filter plate 103. At the same time, the torque of the torsion spring 108 drives the rotating shaft 106 and the sealing plate 105 to rotate, so that the sealing plate 105 seals and covers the disassembly hole of the filter plate 103, thereby preventing external dust and impurities from entering the purification box 101 and causing unnecessary pollution to the oil circuit. Example

[0027] Based on Implementation 1, existing technologies also have the problem that lubricating oil generates heat during use, thus affecting normal lubrication, while ensuring the sealing effect of oil circuit connections is also necessary. Please refer to... Figures 5-6This embodiment provides a wheelset axle box lubrication structure with oil circulation and purification, which can effectively solve the sealing problem of oil circuit connection and the cooling effect of lubricating oil during normal use. The oil circulation and purification wheelset axle box lubrication structure includes a cooling device comprising a semiconductor cooler 201. Fins 202 are fixedly mounted on the top surface of the semiconductor cooler 201, and a mounting bracket 203 is fixedly mounted on the bottom surface of the semiconductor cooler 201. A fan 204 is mounted at the bottom of the mounting bracket 203. The top surface of the semiconductor cooler 201 abuts against the bottom surface of the oil reservoir 1. The fins 202 are fixedly installed inside a rectangular hole in the bottom surface of the oil reservoir 1. The fan 204 is detachably installed inside a mounting hole in the middle of the bottom surface of the mounting bracket 203.

[0028] The conveying connection device includes an oil outlet pipe 301, with an oil pump 302 connected to the left end of the oil outlet pipe 301.

The oil outlet pipe 301 is fixedly installed on the left side of the oil storage tank 1 near the bottom. The input end of the oil pump 302 and the left end of the oil outlet pipe 301 are connected through the flange 303.

[0029] By using a cooling device and a conveying connection device, the semiconductor cooler 201 and fins 202 facilitate the cooling of the lubricating oil, ensuring the normal use effect of the lubricating oil. At the same time, the flange 303 and sealing ring 304 ensure the sealing effect at the connection.

[0030] When cooling the lubricating oil in the oil circuit, the semiconductor cooler 201 is activated to cool the oil, and the fins 202 transfer the cooling energy to the inside of the oil tank 1 to cool the lubricating oil. The fan 204 is activated to cool the heat dissipation surface of the semiconductor cooler 201 to ensure the cooling effect of the lubricating oil. The oil pump 302 is activated to pump the lubricating oil through the oil outlet pipe 301. During the connection between the pipelines, the flange 303 is used for connection and fixation, and the installation of inner and outer sealing rings 304 ensures the sealing effect of the pipeline connection.
