Description
Technical Field
[0001] The utility model relates to the technical field of protection components, and in particular to a protection component for short circuit of a power exchange cabinet. Background Art
[0002] A battery swap cabinet is a cabinet that can store electric vehicle batteries and charge automatically. It has many grids, which are battery compartments. Each battery compartment can store an electric vehicle battery, and the electric vehicle battery can be charged and replaced through the display screen or QR code on the cabinet. According to the publication number: CN220281141U, a new type of battery swap cabinet battery compartment structure is disclosed, including: a main body component; the main body component includes a battery; a protective component; the protective component includes two groups of connecting rods arranged on the outer side surface of the battery, a connecting frame connected to the top of the connecting rod, three groups of movable rods arranged between the bottom of the connecting rod, and a protective plate connected to the top of the connecting frame and the outside of the connecting rod; it also includes an auxiliary component connected to the bottom end of the connecting rod. The utility model solves the problem that the existing batteries are charged inside the battery compartment by connecting them to the charging piles in the compartment through charging cables, and if an emergency occurs during charging, such as a battery fire caused by a short circuit in the wires, the batteries cannot be isolated separately in the compartment, which eventually leads to the scrapping of the entire battery swap cabinet. At the same time, the batteries are heavy, and when they are placed in the compartment, they are prone to collide with the bottom surface of the compartment, causing battery damage. However, the above technology still has some defects. For example, the short-circuit protection components of the existing power swap cabinets are mostly directly arranged on the back of the cabinet, which is not convenient for staff to maintain after long-term use, and it is easy to cause the cabinet to be damaged due to short circuit. The practicality is poor and needs to be improved. Utility Model Content

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:
[0012] 1. The utility model achieves a better use effect by arranging a card slot, a card plate, a protective cover, a fixed slot, a rotating slot, a threaded rod and a turning handle. After long-term use, when it is necessary to maintain the short-circuit component inside, the turning handle can be pinched to rotate, so that the threaded rod can be rotated to both sides inside the support plate through the rotating slot. When the threaded rod is completely rotated out of the interior of the support plate through the rotating slot, it can be taken out from the inside of the protective cover through the fixed slot. At this time, pinch the protective cover and pull it backwards to make the card plate slide out of the interior of the cabinet through the card slot. This avoids the situation where the short-circuit protection components of the existing power exchange cabinets are mostly directly arranged on the back of the cabinet, which is not convenient for the staff to maintain after long-term use and is easy to cause the cabinet to be damaged due to short circuit.
[0013] 2. The utility model is provided with a limit plate, a limit groove, a fixing ring and a dustproof plate, so that it is more convenient to protect the heat dissipation port.

By setting the card slot 8, the card plate 9, the protective cover 10, the fixed slot 11, the rotating slot 12, the threaded rod 13 and the turning handle 14, a better use effect is achieved. After long-term use, when it is necessary to maintain the short-circuit component inside, the turning handle 14 can be pinched to rotate, so that the threaded rod 13 can be rotated to both sides inside the support plate 7 through the rotating slot 12. When the threaded rod 13 is completely rotated out of the interior of the support plate 7 through the rotating slot 12, it can be taken out from the inside of the protective cover 10 through the fixed slot 11. At this time, pinch the protective cover 10 and pull it backwards to make the card plate 9 slide out of the interior of the cabinet 1 through the card slot 8, thereby avoiding the short-circuit protection component of the existing power exchange cabinet. Most of them are directly set on the back of the cabinet 1, which is not convenient for the staff to maintain after long-term use, and it is easy to cause the cabinet 1 to be damaged due to short circuit. The support columns 2 are evenly distributed at the four corners of the bottom end of the cabinet 1, the heat dissipation ports 3 are symmetrically distributed at the left and right ends of the cabinet 1, and the hinges 4 are symmetrically distributed at the upper and lower ends of the surface of the cabinet 1. The cover plate 5 is rotatably connected to the cabinet 1, which is more convenient for the cover plate 5 to rotate and prevents the cover plate 5 from being stuck by the cabinet 1 during use, causing the cover plate 5 to be unable to continue to rotate. The card plate 9 is slidably connected to the cabinet 1, the protective cover 10 is slidably connected to the cabinet 1, and the protective cover 10 is slidably connected to the support plate 7, which is more convenient for the card plate 9 and the protective cover 10 to rotate. The locking member 12 is connected to the cabinet 1 by the screw thread 13 and the protective cover 10 by the screw thread 13. The locking member 12 is connected to the cabinet 1 by the screw thread 13 and the protective cover 10 by the screw thread 13. The locking member 12 is connected to the cabinet 1 by the screw thread 13 and the protective cover 10 by the screw thread 13. The locking member 12 is connected to the cabinet 1 by the screw thread 13 and the protective cover 10 by the screw thread 13.
[0025] Embodiment 2
[0026] See also Figure 1-3 5. A limit plate 15 is fixedly installed on the side of the cabinet 1. A limit groove 16 is provided inside the limit plate 15. A fixing ring 17 is slidably connected inside the limit groove 16. A dustproof plate 18 is fixedly installed on the side of the fixing ring 17, which is more convenient for protecting the heat dissipation port 3. Before use, pinch the fixing ring 17 corresponding to the upper limit groove 16 and press downward to make the fixing ring 17 slide downward on the top of the limit plate 15 through the limit groove 16. When the fixing ring 17 completely slides into the interior of the limit plate 15 through the limit groove 16, the dustproof plate 18 is firmly stuck on the heat dissipation port through the fixing ring 17. 3, thereby preventing the situation in which external impurities splash into the cabinet 1 through the heat dissipation port 3 during use and causing damage to the internal electrical components. The limit plates 15 are symmetrically distributed at the left and right ends of the cabinet 1. The fixing ring 17 is slidably connected to the limit plates 15, the fixing ring 17 is slidably connected to the cabinet 1, the dustproof plate 18 is slidably connected to the limit plates 15, and the dustproof plate 18 is slidably connected to the cabinet 1, which makes it easier for the fixing ring 17 to slide and avoids the situation in which the fixing ring 17 is stuck by the limit plates 15 during use and the fixing ring 17 cannot continue to slide.
[0027] Working principle: When in use, first place the cabinet 1 in the required position, so that the support column 2 can support the cabinet 1 steadily, then pinch the pull block 6 and pull it backwards, so that the cover plate 5 can rotate backwards on the surface of the cabinet 1 through the hinge 4. When the cover plate 5 is fully opened, the internal electrical components can be installed or replaced, and then the fixing ring 17 can be pinched to correspond to the upper limit groove 16 and pressed downward to make the fixing ring 17 slide downward on the top of the limit plate 15 through the limit groove 16. When the fixing ring 17 completely passes through the limit groove 16 and slides completely into the inside of the limit plate 15, it can be done, and at this time, the fixing ring 17 drives the dustproof plate 18 to completely wrap the heat dissipation port 3, thereby preventing it from being used excessively. During the process, external impurities may splash into the interior of the cabinet 1 through the heat dissipation port 3, causing damage to the internal electrical components. After long-term use, when it is necessary to maintain the short-circuit component, the handle 14 can be pinched and rotated to make the threaded rod 13 rotate to the left and right ends inside the support plate 7 through the rotation groove 12. When the threaded rod 13 is completely rotated out of the interior of the support plate 7 through the rotation groove 12, it can be taken out from the inside of the protective cover 10 through the fixed groove 11, and then the protective cover 10 is pinched and pulled backwards to make the protective cover 10 slide backwards on the top of the support plate 7, and at this time, the card plate 9 slides out of the interior of the cabinet 1 through the card slot 8, so that the staff can maintain the short-circuit component.
