Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0029] As Figures 1-7 shown, a guide rail device for an inverter module includes: an electric cabinet 1, a guide rail 3, and a mounting plate 6,

[0030] Inside the electrical cabinet 1, there is an inverter module 5. The bottom end of the inverter module 5 is fixedly connected to a support frame 4. The bottom end of the support frame 4 is cooperatively connected to a moving component. A guide rail 3 is arranged at the bottom of the inverter module 5, and the guide rail 3 is cooperatively connected to the moving component. When the inverter module 5 needs to be installed in the electrical cabinet 1, the staff places the moving component fixed to the bottom end of the support frame 4 on the guide rail 3, and the moving component moves along the inner wall of the guide rail 3. The moving component and the guide rail 3 cooperate, thus achieving the effect of facilitating the pushing or pulling out of the inverter module 5, avoiding the phenomenon that the friction generated when the inverter module 5 moves in the electrical cabinet 1 damages the inverter module 5. The guide rail 3 can provide a guiding function for the inverter module 5 during disassembly and assembly through the moving component, avoiding the phenomenon that the inverter module 5 collides with the inner wall of the electrical cabinet 1 during disassembly and assembly, thereby ensuring the safety of the inverter module 5 during disassembly and assembly;

[0031] There are two groups of mounting plates 6, which are respectively fixedly connected to both ends of the inverter module 5. The mounting plates 6 are cooperatively connected to the inner wall of the electrical cabinet 1. When the inverter module 5 is installed on the guide rail 3 through the moving component, the staff fixes the mounting plates 6 to the inner side wall of the electrical cabinet 1 with bolts, thereby ensuring the stability of the inverter module 5 installed on the electrical cabinet 1. The mounting plates 6 are arranged on both sides of the inverter module 5, facilitating the staff to carry out disassembly and assembly.

[0032] In some specific implementation schemes, fixing frames 2 are respectively arranged on both sides of the bottom end of the guide rail 3. The upper and lower ends of the fixing frames 2 are respectively fixedly connected to the guide rail 3 and the electrical cabinet 1. The fixing frames 2 provide a supporting function for the guide rail 3, thereby supporting the inverter module 5 and avoiding the influence of water on the inverter module 5 when water accumulates at the bottom of the electrical cabinet 1 during the use of the electrical cabinet 1.

[0033] In some specific implementation schemes, there are two groups of moving components, which are respectively located at both ends of the support frame 4. The moving component includes: rollers 11, moving rods 14, damping columns 15 and balls 16. The outer wall of the moving rod 14 is fixedly connected to the damping columns 15. There are several groups of balls 16, and several balls 16 are clamped inside the rollers 11. The rollers 11 cooperate with the inner wall of the guide rail 3, and the rollers 11 are cooperatively connected to the moving rods 14. The guide rail 3 is cooperatively connected to an oil injection component. When the moving component operates, the rollers 11 roll along the inner wall of the guide rail 3, and the balls 16 clamped inside the rollers 11 roll along the bottom surface of the moving rod 14, so that the moving rod 14 moves. The moving rod 14 drives the inverter module 5 to move through the support frame 4, thus achieving the effect of pulling out or pushing in the inverter module 5. The balls 16 reduce the friction generated by the contact between the rollers 11 and the moving rods 14.

[0034] In some specific embodiments, positioning holes 12 are respectively formed at both ends of the bottom of the support frame 4. The damping columns 15 are slidably connected to the inner walls of the positioning holes 12. A spring 13 is sleeved and connected to the outer wall of the moving rod 14. The upper and lower ends of the spring 13 are respectively fixedly connected to the inner wall of the positioning hole 12 and the damping column 15. When the moving assembly operates, vibrations will be generated when the rollers 11 roll along the inner wall of the guide rail 3. The vibrations are transmitted to the spring 13 through the moving rod 14 and the damping column 15. The spring 13 buffers the vibrations. At the same time, the damping column 15 slides along the inner wall of the positioning hole 12. The sliding friction generated by the sliding of the damping column 15 provides a damping effect for the spring 13. The abutment of the damping column 15 against the inner wall of the positioning hole 12 provides a positioning function for the moving rod 14. The spring 13 is sleeved on the outer wall of the moving rod 14 to prevent the spring 13 from being bent during operation.

[0035] In some specific embodiments, the oil injection assembly includes: an oil storage tank 7, a connecting pipe 8, an injector 9 and a nozzle 10. The oil storage tank 7 is fixedly connected to the side end of the support frame 4. The connecting pipe 8 is arranged between the support frame 4 and the guide rail 3 and is fixedly connected to the injector 9 and the connecting pipe 8 at both ends respectively. The injector 9 is fixedly connected to the bottom end of the support frame 4. The nozzle 10 is fixedly connected to the bottom end of the injector 9 and the nozzle 10 is arranged inside the guide rail 3. The nozzle 10 cooperates with the moving assembly. A plurality of oil injection holes 17 are respectively formed around the nozzle 10, and an oil injection hole 17 is formed at the bottom end of the nozzle 10. When the inverter module 5 is overhauled after long-term use, the lubricating oil in the moving assembly and the guide rail 3 will be lacking. It is difficult for the moving assembly to move on the guide rail 3. In order to reduce the friction generated when the moving assembly moves on the guide rail 3, when the moving assembly operates, the injector 9 automatically operates. The injector 9 extracts the lubricating oil stored in the oil storage tank 7 through the connecting pipe 8, and then the injector 9 sprays the lubricating oil through the nozzle 10. The lubricating oil is sprayed on the inner side end of the guide rail 3, the rollers 11 and the balls 16 through the oil injection holes 17 formed around. At the same time, the lubricating oil is sprayed on the inner bottom end of the guide rail 3 through the oil injection hole 17 formed at the bottom end of the nozzle 10. The lubrication can reduce the friction of the moving assembly moving along the guide rail 3, extend the service life of the moving assembly and the guide rail 3, and at the same time, reduce the burden on the staff for disassembly and assembly through the moving assembly.

[0036] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
