Technical Field
[0001] This utility model relates to the field of power equipment technology, and in particular to a heat dissipation box for a distribution automation station terminal. Background Technology
[0002] As a key piece of equipment in the smart grid, distribution automation substation terminals need to monitor and control the power system's operating status in real time. Their internal electrical components generate a significant amount of heat during prolonged operation. To ensure stable operation, the heat dissipation enclosure becomes a crucial component of the distribution automation substation terminal. It must not only efficiently dissipate heat but also possess excellent protective performance and convenient maintainability to adapt to complex environments such as outdoor substations and switching stations.
[0003] Currently, the heat dissipation enclosures of traditional distribution automation substations mostly adopt a fixed structure design. The mounting plate inside the enclosure is usually fixed to a preset position by bolts or other means, and electrical components are directly mounted on the plate; the heat dissipation system relies on fixed-layout heat dissipation holes, heat sinks or fans for passive or active heat dissipation; the dustproof structure uses non-removable filters or a sealed design.
[0004] Because the mounting plate is fixed in position, when it is necessary to replace electrical components of different specifications or perform maintenance operations, the staff often have to carry out complicated disassembly and assembly work inside the small box. This not only consumes a lot of time, but also makes the operation difficult and can easily cause problems such as component damage or poor circuit contact. Therefore, a heat dissipation box for the terminal of the power distribution automation station is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a heat dissipation box for the terminal of a power distribution automation station, aiming to improve the problem that the fixed position of the mounting plate inside the traditional power distribution box is difficult to adjust flexibly, resulting in inconvenience for the installation and maintenance of electrical components.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] The dustproof component includes a dustproof frame that covers the side wall of the cooling fan, and a connecting block is fixedly connected to the side wall of the dustproof frame.
[0011] As a further description of the above technical solution:
[0012] A connecting frame is fixedly connected to the side wall of the distribution box, and the side wall of the connecting block is slidably connected inside the connecting frame. A vertical groove is opened inside the connecting frame.
[0013] As a further description of the above technical solution:
[0014] The connecting frame is provided with a locking block, the side wall of which is slidably connected to the inside of the vertical groove and the connecting block.
[0015] As a further description of the above technical solution:
[0016] A sleeve is provided inside the connecting frame, and the side wall of the sleeve is fixedly connected to the inside of the vertical groove.

[0021] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, when it is necessary to adjust the position of the mounting plate for the installation or maintenance of electrical components, the operator moves the lever, causing the locking pin to slide on the side wall of the connecting rod, compressing the first spring and moving it out of the slide rail, releasing the sliding frame from its fixed position, allowing it to slide along the slide rail to adjust its position. After adjustment, the lever is released, and the first spring pushes the locking pin back into the slide rail slot, fixing the sliding frame. This solves the problem of the fixed position of the mounting plate inside the traditional distribution box, which is difficult to adjust flexibly, resulting in inconvenience for the installation and maintenance of electrical components.

[0025] 2.

After the locking block is disengaged from the connecting block groove, the dustproof frame can be taken out for cleaning or replacement. This solves the problem that the traditional dustproof structure is fixed by bolts, which makes it inconvenient to clean or replace the dustproof components regularly. The above technical solution improves the convenience of disassembling and installing the dustproof frame. Attached Figure Description

[0034] 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.
[0035] Reference Figures 1-4This utility model provides an embodiment of a heat dissipation box for a terminal of a power distribution automation station, including a power distribution box 1. A door 2 is rotatably connected to the side wall of the power distribution box 1. A rain shield 3 is fixedly connected to the upper surface of the power distribution box 1. The rain shield 3 is used to prevent rainwater from directly hitting the top and heat dissipation vents of the power distribution box 1, thus preventing rainwater from entering the box and causing short circuits or moisture damage to electrical components. A cooling fan 4 is installed inside the power distribution box 1 to accelerate airflow inside the box, thereby expelling heat through forced convection and reducing the operating temperature of electrical components. To prevent excessive temperature from affecting equipment performance or shortening its lifespan, the side wall of distribution box 1 is equipped with a dustproof component, and the interior of distribution box 1 is equipped with a moving component. The moving component includes a sliding frame 6, and a slide rail 5 is fixedly connected inside distribution box 1. The side wall of the sliding frame 6 is slidably connected to the side wall of the slide rail 5. The slide rail 5 cooperates with the sliding frame 6 to slide, allowing the sliding frame 6 to move smoothly along the slide rail 5 within distribution box 1. This facilitates the adjustment of the position of the mounting plate 7 for the installation or maintenance of components. The side wall of the sliding frame 6 is fixedly connected to the mounting plate. 7. Mounting plate 7 is used to install electrical components of the distribution automation station terminal and provide fixed support for the components. A fixed frame 8 is provided on the side wall of the sliding frame 6. A locking post 9 is slidably connected inside the fixed frame 8. A lever 10 is fixedly connected to the side wall of the locking post 9. A connecting rod 11 is fixedly connected inside the fixed frame 8. A first spring 12 is sleeved on the side wall of the connecting rod 11. By moving the lever 10, the locking post 9 is driven into the fixed frame 8 and moves against the side wall of the connecting rod 11, compressing the first spring 12. The locking post 9 moves out of the slide rail 5, realizing the locking post 9 and the slide rail. The separation or engagement movement of 5 achieves the fixation or unlocking of the sliding frame 6, facilitating the movement of the sliding frame 6 to move the mounting plate 7. The side wall of the fixed frame 8 is fixedly connected to the fixed block 13, which is internally fixedly connected to the side wall of the sliding frame 6. The side wall of the locking post 9 is slidably connected to the inside of the slide rail 5. The side wall of the lever 10 is slidably connected to the inside of the fixed frame 8. The locking post 9 and the lever 10 are slidably connected to the side wall of the connecting rod 11. One end of the first spring 12 is fixedly connected to the side wall of the lever 10, and the other end of the first spring 12 is fixedly connected to the inside of the fixed frame 8.
[0036] Reference Figures 5-6The dustproof component includes a dustproof frame 14, which covers the side wall of the cooling fan 4 to prevent external dust and debris from entering the distribution box 1 through the cooling fan 4, thus avoiding dust accumulation that could affect heat dissipation or cause short circuits. The dustproof frame 14 covers the side wall of the cooling fan 4, and a connecting block 15 is fixedly connected to the side wall of the dustproof frame 14. A connecting frame 16 is fixedly connected to the side wall of the distribution box 1. The side wall of the connecting block 15 is slidably connected inside the connecting frame 16, allowing the connecting block 15 to slide in conjunction with the connecting frame 16, providing installation guidance and support for the dustproof frame 14, facilitating its installation and removal. A vertical groove 17 is provided inside the connecting frame 16, and a locking block 18 is also provided inside the connecting frame 16. The side wall is slidably connected inside the vertical groove 17, the side wall of the locking block 18 is slidably connected inside the connecting block 15, and a sleeve 19 is provided inside the connecting frame 16. The side wall of the sleeve 19 is fixedly connected inside the vertical groove 17, and a second spring 20 is provided inside the connecting frame 16. One end of the second spring 20 is fixedly connected to the side wall of the locking block 18, and the other end of the second spring 20 is fixedly connected to the inside of the sleeve 19. The locking block 18, the sleeve 19, and the second spring 20 cooperate with each other. When installing the dustproof frame 14, the locking block 18 automatically engages with the slot of the connecting block 15 under the action of the second spring 20. When disassembling, pressing the locking block 18 compresses the second spring 20 and disengages it from the slot, thus achieving quick fixing and disassembly of the dustproof frame 14 and facilitating maintenance.
[0037] Working principle: When it is necessary to adjust the position of the mounting plate 7 to install or maintain electrical components, the operator moves the lever 10, which causes the locking pin 9 to slide within the fixed frame 8 and move along the side wall of the connecting rod 11, compressing the first spring 12 and causing the locking pin 9 to move out of the slide rail 5, thereby releasing the fixation of the sliding frame 6. At this time, the sliding frame 6 can slide smoothly along the side wall of the slide rail 5, moving the mounting plate 7 to the required position. After the adjustment is completed, the lever 10 is released, the first spring 12 resets and pushes the locking pin 9 to re-engage in the slot of the slide rail 5, fixing the sliding frame 6 for easy installation or maintenance.
[0038] During the operation of the heat dissipation box, the dustproof frame 14 covers the side wall of the heat dissipation fan 4, continuously intercepting dust and debris to prevent them from entering the power distribution box 1. When it is necessary to clean or replace the dustproof frame 14, the staff pulls the dustproof frame 14, causing the connecting block 15 to slide in the connecting frame 16. As the connecting block 15 moves, it squeezes the locking block 18, causing the locking block 18 to slide in the vertical groove 17 and compress the second spring 20. When the locking block 18 is completely disengaged from the locking groove of the connecting block 15, the fixed state of the dustproof frame 14 is released, and it can then be taken out for cleaning or replacement.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
