[0002] A mobile box-type substation is a mobile box-type substation that is generally constructed of a sturdy metal box (usually steel or aluminum), which integrates transformers, circuit breakers, terminal blocks, and other necessary power equipment. These boxes are usually waterproof, dustproof, and corrosion-resistant to adapt to various environmental conditions. Traditional mobile box-type substations (also known as box-type substations or containerized substations) are a type of power equipment with a certain degree of flexibility and convenience, mainly used for power distribution and transformation in power systems. They are usually designed as a closed box that integrates power facilities such as transformers, switchgear, and protection devices.

[0003] The traditional box-type mobile substation is moved by the universal wheels equipped at the bottom. However, during the movement, due to the single structure between the box and the universal wheels and the lack of a shock-absorbing mechanism, the equipment in the box may be damaged by vibration. Therefore, a box-type mobile substation is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 3A box-type mobile substation includes an electric box 1, the lower surface of the electric box 1 is fixedly connected to a base 2, the side wall of the base 2 is slidably connected to a shock-absorbing box 3, and a moving component is provided at the bottom of the shock-absorbing box 3, which is used to move the electric box 1. The inside of the shock-absorbing box 3 is fixedly connected to a chassis 5, the side wall of the chassis 5 is fixedly connected to a load-bearing block 6, the side wall of the load-bearing block 6 is slidably connected to a connecting frame 7, the inside of the connecting frame 7 is slidably connected to a load-bearing block 8, the upper surface of the load-bearing block 8 is fixedly connected to a chassis 2 9, and the upper surface of the chassis 2 9 is fixedly connected to the lower surface of the base 2. The lower surface of chassis 2 (9) is fixedly connected to a holder (10). A connecting plate (11) is rotatably connected to the side wall of holder (10). A fixing frame (12) is fixedly connected to the side wall of connecting frame (7). A guide column (15) is fixedly connected to the interior of fixing frame (12). A first spring (14) is sleeved on the side wall of guide column (15). A slider (13) is slidably connected to the side wall of guide column (15). The side wall of first spring (14) is slidably connected to slider (13). One end of first spring (14) is fixedly connected to the interior of fixing frame (12). A damper (16) is provided between the side walls of bearing block (1) (6) and bearing block (2) (8). The mobile assembly includes wheels (4), which are provided at the bottom of shock absorber box (3).

[0033] When the device inevitably vibrates during movement, the force generated by the vibration causes the base 2 to slide toward the inside of the shock absorber box 3. This sliding movement causes the load-bearing block 2 8 and chassis 2 9 to squeeze and move up and down. This movement further causes the connecting plate 11 to rotate within the holder 10. As the connecting plate 11 rotates, the slider 13 also begins to slide within the fixing frame 12. The movement of the slider 13 generates a force that deforms and squeezes the first spring 14. This squeezing causes the load-bearing block 2 8 to slide downward within the connecting frame 7, applying pressure to the damper 16. In this way, the force generated by the vibration is transferred to the damper 16. The function of the damper 16 is to weaken the force generated by the vibration, thereby reducing the potential damage to the device. When the force generated by the vibration gradually disappears, the damper 16 uses its internal mechanism to push the load-bearing block 2 8 to move, allowing the device to return to its original state. This process effectively reduces the damage caused by vibration to the device, ensuring its stability and service life.

[0034] Reference Figure 4-Figure 5An exhaust rack 17 is fixedly connected to the side wall of the electrical box 1. A filter rack 18 is provided on the side wall of the exhaust rack 17. A fixed plate 19 is fixedly connected to the side wall of the filter rack 18. A guide platform 21 is slidably fixedly connected to the interior of the fixed plate 19. A second spring 20 is provided between the guide platform 21 and the fixed plate 19. One end of the second spring 20 is fixedly connected to the interior of the fixed plate 19, and the other end of the second spring 20 is fixedly connected to the guide platform 21. A sphere 22 is fixedly connected to the side wall of the guide platform 21. A fixing block 23 is provided on the side wall of the exhaust rack 17. A bolt 24 is threadedly connected to the interior of the fixing block 23. The side wall of the bolt 24 is threadedly connected to the interior of the exhaust rack 17. A groove block 25 is fixedly connected to the side wall of the fixing block 23. The side wall of the groove block 25 is slidably connected between the spheres 22. A fan 26 is fixedly connected to the interior of the electrical box 1. The side wall of the fan 26 is provided on one side of the exhaust rack 17.

[0035] When the temperature inside the electrical box 1 becomes too high, fan 26 is activated to draw air from outside into the box 1. This draws cool air in, helping to lower the temperature inside. As the air is drawn into the box 1, it first passes through the filter frame 18. The filter frame 18 ensures clean air entering the box 1 by effectively filtering out impurities and dust. Over time, excessive dust may accumulate inside the filter frame 18, hindering air circulation. Regular cleaning and maintenance are required. If excessive dust accumulates inside the filter frame 18, obstructing air circulation, the filter frame 18 can be moved by pulling the handle on the frame. As the filter frame 18 moves outward, the ball 22 is squeezed by the groove block 25. This squeezing action causes the ball 22 to slide along the groove block 25 toward the interior of the fixing plate 19. During this process, the ball 22 exerts pressure on the second spring 20, causing it to deform and contract. As the second spring 20 contracts, the connection between the groove block 25 and the ball 22 gradually separates, allowing the filter frame 18 to be easily removed. After removing the filter frame 18, clean any accumulated dust and impurities. After cleaning, reinstall the filter frame 18. First, align the filter frame 18 with the exhaust frame 17 to ensure it is correctly positioned. Then, press the filter frame 18 inward. During this process, the ball 22 is again squeezed by the groove block 25 and guided toward the interior of the fixed plate 19. As the ball 22 slides, it applies pressure to the second spring 20, causing it to deform and contract. When the ball 22 is fully inserted into the fixed plate 19, the groove block 25 and ball 22 engage, completing the installation of the filter frame 18 to the exhaust frame 17. In this way, the filter frame 18 is securely fixed in place, restoring its filtering function and ensuring air circulation and cooling within the electrical box 1.

[0036] Working principle: When the temperature inside the electrical box 1 is too high, the fan 26 can be started to transport external airflow into the electrical box 1 for cooling, thereby reducing the damage to the equipment caused by high temperature. When the external airflow flows through the filter frame 18, the filter frame 18 will filter the air. When too much dust accumulates inside the filter frame 18, affecting the air intake, the handle on the filter frame 18 is pulled to move the filter frame 18 outward. At this time, the ball 22 is squeezed by the groove block 25, sliding toward the inside of the fixed plate 19, and squeezing the second spring 20, causing it to shrink and deform, so that the groove block 25 is separated from the ball 22, and the filter frame 18 is removed. When the filter frame 18 is installed after cleaning, it is aligned with the exhaust frame 17 and then pressed. At this time, the ball 22 is squeezed by the groove block 25, thereby sliding toward the inside of the fixed plate 19 and squeezing the second spring 20 to shrink and deform, so that the groove block 25 is engaged with the ball 22, thereby completing the installation of the filter frame 18 and the exhaust frame 17.

[0037] When the equipment vibrates during movement, the force generated by the vibration will cause the base 2 to slide toward the inside of the shock-absorbing box 3, driving the load-bearing block 2 8 and the chassis 2 9 to squeeze and move up and down. This movement will cause the connecting plate 11 to rotate in the fixer 10, thereby driving the slider 13 to slide inside the fixing frame 12. At the same time, the force generated by the movement of the slider 13 will cause the first spring 14 to deform and squeeze, causing the load-bearing block 2 8 to slide downward inside the connecting frame 7 and squeeze the damper 16, transferring the force generated by the vibration to the damper 16. The damper 16 will weaken the force generated by the vibration. When the force gradually disappears, the damper 16 will push the load-bearing block 2 8 to move, restoring the equipment to its initial state, reducing the loss of the equipment to the vibration.
