[0032] 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.

[0033] Reference Figures 1-5 An embodiment of this utility model is provided: a train direct power supply test bench, including a test bench body 1, a lifting component connected to the side of the test bench body 1, a detachable component connected inside the lifting component, a limit groove 2 opened inside the test bench body 1, a collection drawer 3 slidably connected inside the limit groove 2, and a separator component connected inside the collection drawer 3.

[0034] The lifting assembly includes a fixed plate 4, which is fixedly connected to the side of the test bench body 1. A threaded rod 8 is rotatably connected to the bottom of the fixed plate 4. A movable plate 6 is threadedly connected to the outer wall of the threaded rod 8. A gear 9 is fixedly connected to the outer wall of the threaded rod 8. A slide groove 10 is opened on the side of the test bench body 1. A slider 11 is slidably connected in the slide groove 10. A rack 12 is fixedly connected to the side of the slider 11. The rack 12 meshes with the gear 9. A hydraulic rod 5 is fixedly connected to the rear side of the test bench body 1. The output end of the hydraulic rod 5 is fixedly connected to one end of the rack 12. The movable plate 6 slides on the side of the test bench body 1. Connecting plates 13 are fixedly connected to both ends of the movable plate 6 to facilitate the sliding of the movable plate 6 on the side of the test bench body 1 and drive the connecting plates 13 on both sides to rise and fall.

[0035] The detachable components include a fixing bolt 15, a threaded groove 14 in the connecting plate 13, the fixing bolt 15 being threaded into the threaded groove 14, a cooling fan 16 being connected to the bottom of the connecting plate 13, a connecting groove being opened at the top of the cooling fan 16, and the fixing bolt 15 being threaded into the connecting groove at the bottom; the separating components include a crossbar 17, the crossbar 17 being fixedly connected to the inner wall of the collection drawer 3, a moving block 18 being slidably connected to the outer wall of the crossbar 17, the moving block 18 sliding on the inner wall of the collection drawer 3, a baffle 19 being fixedly connected to the side of the moving block 18, and multiple sets of moving blocks 18; the crossbar 17 is parallel to the bottom of the collection drawer 3; the slide 10 and the slider 11 are both T-shaped; a heat dissipation window 7 is opened on the outer wall of the test bench body 1; a handle 20 is fixedly connected to the side of the collection drawer 3; a limit plate 21 is rotatably connected to the side of the test bench body 1 to facilitate limiting the position of the collection drawer 3.

[0036] Working principle: In the train direct power supply test bench, the hydraulic rod 5 is activated to drive the rack 12 to move, which in turn drives the slider 11 to slide in the slide groove 10. This causes the rack 12 to drive the gear 9 to rotate, which in turn drives the threaded rod 8 to rotate. The threaded rod 8 drives the moving plate 6 to slide on the side of the test bench body 1, which in turn drives the connecting plates 13 on both sides to rise and fall. This facilitates the cooling fan 16 to reciprocate and dissipate heat from the test bench body 1, preventing excessive heat buildup that could damage electronic components. The fixing bolts 15 are unscrewed from the threaded groove 14 and the connecting groove at the top of the cooling fan 16, making it easy to disassemble the cooling fan 16. Conversely, unscrewing the bolts also facilitates installation, allowing for disassembly, repair, or replacement of the cooling fan 16. The moving block 18 slides along the crossbar 17, causing the baffles 19 to slide and adjust their positions, facilitating the classification and placement of test-related tools and items for better storage and easy retrieval.

[0037] All electrical components mentioned in this article are electrically connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific embodiments disclosed herein.
