DETAILED DESCRIPTION

[0028] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0029] Example

[0030] As mentioned in the background technology, the existing distribution cabinet has a poor rainproof effect. It only seals the top plate to prevent rain, but leakage will still occur at the sealing position. When rainwater flows on the top plate, it is close to the front and rear ends of the distribution cabinet. On rainy days with a breeze, the falling rainwater will be blown to the front and rear ends of the distribution cabinet, and enter the distribution cabinet through the door panels and ventilation positions. In addition, the top plate of the distribution cabinet is exposed to the outdoors for a long time, and the long-term erosion of rainwater can easily cause damage, affecting the sealing effect. Therefore, the inventor has improved the existing distribution cabinet and designed a new rainproof component, which is explained in detail below with reference to the drawings.

[0031] This embodiment provides a rainproof component for a power distribution cabinet, see Figure 1The rainproof component is installed with the distribution cabinet body 1, and includes a rainproof top plate 2 installed on the top of the distribution cabinet body 1. The rainproof top plate 2 is in the shape of a pointed top and is inclined toward the front and rear end surfaces of the distribution cabinet body 1. That is, the middle position of the rainproof top plate 2 is higher than the two ends, so that the rainproof top plate 2 forms two slopes, and the inclination direction is toward the front and rear end surfaces of the distribution cabinet body 1, so that when rainwater falls on the rainproof top plate 2, it can slide down along the slope.

[0032] In this embodiment, the two ends of the rainproof top plate 2 extend beyond the front and rear ends of the power distribution cabinet body 1. Figure 5 , which can divert rainwater on the rainproof top plate 2 to the outside of the distribution cabinet body 1, and is connected to U-shaped grooves 3 at both ends, with its opening facing upward and sealed at both ends. In addition, the bottom of the rainproof top plate 2 is provided with multiple guide grooves 7 along the length direction, and the guide grooves 7 are connected to the U-shaped grooves 3, which can divert rainwater on the rainproof top plate 2 and divert the rainwater.

[0033] It should be noted that limiting plates 5 are connected on both sides of the rainproof top plate 2, and the limiting plates 5 can block the two ends of the rainproof top plate 2, and vertically arranged rainproof side plates 6 are installed in the limiting plates 5, and the rainproof side plates 6 are connected to the side of the distribution cabinet body 1. The width of the rainproof side plates 6 is greater than the width of the distribution cabinet body 1, which can effectively protect the side of the distribution cabinet body 1, and the front end of the bottom of the rainproof side plate 6 is set to an arc shape to avoid damage to the staff caused by sharp corners. Secondly, a rainproof rear plate 16 is connected between the two rainproof side plates 6, which can be welded. The rainproof rear plate 16 is located at the rear end of the distribution cabinet body 1, and a shutter 17 is installed on the end face of the rainproof rear plate 16 to facilitate ventilation.

[0034] Specifically, the installation method of the rainproof top plate 2 and the rainproof side plate 6 is designed in this solution so that the height of the two can be adjusted to adapt to the use of distribution cabinets of different heights. A plurality of mounting tubes 9 are installed on the upper end of the distribution cabinet body 1. In this solution, four mounting tubes 9 are sufficient, and a plurality of plug-in columns 10 are correspondingly installed on the end surface of the rainproof top plate 2. Four plug-in columns 10 are correspondingly arranged, and the plug-in columns 10 can be correspondingly inserted into the mounting tubes 9 for fixation. Moreover, the mounting tubes 9 are provided with a plurality of first threaded holes 11, and a corresponding threaded hole is provided on the side of the plug-in column 10, and the plug-in column 10 is fixed by passing a bolt through any one of the first threaded holes 11 of the mounting tube 9. By fixing different first threaded holes 11 on the mounting tube 9, the rainproof top plate 2 can be fixed at different heights.

[0035] Secondly, a plurality of pillars 12 are installed on the side of the distribution cabinet body 1, combined with Figure 2-Figure 4In this solution, three pillars 12 are provided on both sides of the distribution cabinet body 1, and are arranged in a triangular shape, and the ends of the pillars 12 are connected to mounting plates 13, and the mounting plates 13 are fixed to the rainproof side plates 6 by bolts. Moreover, the inner side of the rainproof side plates 6 is vertically provided with a plurality of slide grooves 14 for sliding the mounting plates 13, and the corresponding rainproof side plates 6 are provided with three slide grooves 14, and the rainproof side plates 6 are vertically provided with a plurality of second threaded holes 15 passing through the slide grooves 14, and the mounting plates 13 are fixed to the rainproof side plates 6 by bolts passing through the second threaded holes 15. The bolts are connected with the second threaded holes 15 of different heights to achieve the fixation of the rainproof side plates 6 at different heights, and the spacing of the second threaded holes 15 in the vertical direction is consistent with the spacing of the first threaded holes 11 in the vertical direction, and the triangular arrangement of the pillars 12 makes the fixation of the rainproof side plates 6 more stable.

[0036] On the basis of the above structure, the bottom of the U-shaped groove 3 is provided with multiple through-flow holes 4, combined with Figure 6 , which can drain the rainwater that slides into the U-shaped groove 3. In this solution, two groups of water flow holes 4 are provided, and are symmetrically provided at both ends of the U-shaped groove 3, that is, close to the edge of the U-shaped groove 3. Moreover, the inner bottom surface of the U-shaped groove 3 is inclined downward from the midline position toward its two ends, so that two slopes are formed along the length direction of the U-shape, and the middle position is higher than the two ends, which can guide the rainwater in the U-shaped groove 3 to flow toward the water flow holes 4 at both ends, thereby accelerating the discharge of rainwater. The design of the U-shaped groove 3 and the water flow holes 4 enable the rainwater in the U-shaped groove 3 to flow relatively far away from the middle of the distribution cabinet body 1, reducing the rainwater adhering to the front and rear end surfaces thereof.

[0037] It should be noted that in order to be able to further divert the water in a direction away from the distribution cabinet body 1, a diversion pipe 8 is connected to the bottom of the water hole 4, and the diversion pipe 8 is inclined in a direction away from the distribution cabinet body 1. By designing the diversion pipe 8 inclined away from the distribution cabinet body 1, the rainwater flowing out of the water hole 4 can flow in a direction away from the front and rear end surfaces of the distribution cabinet body 1, which can further reduce the amount of rainwater adhering to the distribution cabinet, and then reduce the rainwater that penetrates into the distribution cabinet from the front and rear end surfaces, thereby forming effective protection for the surface and internal components.
