[0026] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0027] Example 1: Please refer to Figures 1 to 10 This utility model provides a technical solution: a distributed DC power supply cabinet, including a cabinet door 1, a power cabinet body 2, and a hinge 3. The cabinet door 1 is installed between the cabinet door 1 and the power cabinet body 2 via the hinge 3. A storage groove 17 is provided on the upper part of the power cabinet body 2. A rain shield 4 is inserted into the inner wall of the storage groove 17. A fixing post 7 is installed on the right rear side of the rain shield 4. A limiting groove 16 is provided on the inner bottom wall of the storage groove 17. Multiple drainage grooves 5 are provided on the upper part of the rain shield 4. Multiple drainage grooves are provided on the upper part of the cabinet door 1. Hole 6; The rain shield 4 is installed between the front part and the upper rear side of the cabinet door 1. The fixing post 7 is inserted into the right side of the inner wall of the limiting groove 16, so that when the rain shield 4 is opened, it is hinged along the inner wall of the limiting groove 16 by the fixing post 7 to limit the position of the rain shield 4 and facilitate its subsequent reset. Multiple drainage grooves 5 are all designed with an inclination, and the front end is connected to the drainage hole 6, so that rainwater can be discharged through the drainage groove 5 and through the drainage hole 6 to prevent the accumulation of too much rainwater on the top of the rain shield 4.

[0028] When in use, first pull the cabinet door 1 forward to open it, and use the hinge 3 to hinge with the cabinet door 1, thereby simultaneously pulling the rain shield 4 forward to hinge open, and driving the fixing post 7 to slide along the inner wall of the limiting groove 16, thereby fully opening the rain shield 4, so that maintenance personnel can carry out maintenance operations, preventing rainwater from splashing into the surface of the components. The top of the rain shield 4 has multiple drainage grooves 5, and the rainwater on its surface is guided through the drainage grooves 5 and discharged through the drainage holes 6, thereby improving the performance of the cabinet door 1. After maintenance is completed, close the cabinet door 1, and drive the rain shield 4 to gradually insert into the inner wall of the storage groove 17, so as to facilitate subsequent opening and use, thereby improving the use effect of the power cabinet 2.

[0029] Example 2: Based on Example 1, in order to fix the position of the rain shield 4 after it is opened or closed, a sliding groove 8 is provided inside the fixing post 7. A sliding plate 10 is slidably connected to the lower part of the inner wall of the sliding groove 8. A plug 11 is installed on one side of the sliding plate 10, and an elastic element 9 is installed on the other side. Insertion holes 18 are provided on both the front and rear sides of the bottom wall of the limiting groove 16. The top of the elastic element 9 is installed on the inner top wall of the sliding groove 8. The bottom of the plug 11 penetrates the fixing post 7 and is inserted into the inner wall of one of the insertion holes 18. Thus, the elastic force of the elastic element 9 pushes one end of the plug 11 to maintain the insertion state between it and the insertion hole 18, so as to fix the position of the rain shield 4.

[0030] First, pull the cabinet door 1 forward to open it, and simultaneously pull the rain shield 4 forward to hinge it open. This causes the fixing post 7 to slide along the inner wall of the limiting groove 16. During this process, the plug 11 pushes against the rear socket 18 and is squeezed upward, thereby causing the slide plate 10 to move upward and squeeze the elastic element 9, keeping it compressed in the inner wall of the sliding groove 8. At this time, when the rain shield 4 is open, the fixing post 7 slides along the inner wall of the limiting groove 16, and causes the bottom end of the plug 11 to slide along the inner wall of the limiting groove 16. Then, after the rain shield 4 is fully opened, the plug 11 is pushed into the inner wall of the front socket 18 by the elastic force of the elastic element 9, so as to fix the position of the rain shield 4 after it is opened, thus facilitating maintenance personnel to perform maintenance operations. After maintenance is completed, close the cabinet door 1, and use the elastic force of the elastic element 9 to push the plug 11 into the inner wall of the rear socket 18 to fix the position of the rain shield 4 after it is closed, so as to facilitate subsequent maintenance.

[0031] Example 3: Based on Example 2, in order to scrape the water off the surface of the rain shield 4 and reduce rainwater residue, a movable groove 12 is provided on the upper front side of the power cabinet 2. A movable plate 14 is slidably connected to the lower part of the inner wall of the movable groove 12. Multiple elastic elements 13 are installed on one side of the movable plate 14, and a scraper 15 is installed on the other side. The tops of the multiple elastic elements 13 are all installed on the inner top wall of the movable groove 12, thereby using the elastic elements 13 to increase the compensation of the scraper 15 and maintain its contact with the surface of the rain shield 4. The bottom of the scraper 15 penetrates the storage groove 17 and is in contact with the top surface of the rain shield 4, so that the scraping operation is performed when the rain shield 4 is closed, and the rainwater is scraped forward on the surface of the rain shield 4. After it is reset, it is discharged by the cooperation between the drainage groove 5 and the drainage hole 6.

[0032] Close the cabinet door 1 and gradually insert the rain shield 4 into the inner wall of the storage slot 17. At this time, multiple elastic elements 13 are installed on the inner wall of the moving slot 12. The elastic force of the multiple elastic elements 13 pushes the moving plate 14 down along the inner wall of the moving slot 12, and drives the scraper 15 to stick to the surface of the rain shield 4, thereby scraping the rainwater forward on the surface of the rain shield 4. After the rain shield 4 is completely reset, the scraped rainwater is discharged forward through the drainage slot 5 and the drain hole 6, thereby reducing the amount of rainwater remaining on the surface of the rain shield 4.

[0033] The working process of this utility model is as follows:

[0034] In use, first pull the cabinet door 1 forward to open it, and use the hinge 3 to hinge with the cabinet door 1, thereby simultaneously pulling the rain shield 4 forward to open, and causing the fixing post 7 to slide along the inner wall of the limiting groove 16. During this process, the plug 11 pushes against the rear insertion hole 18 and is squeezed upward, thereby causing the slide plate 10 to move upward and squeeze the elastic element 9, keeping it in a compressed state on the inner wall of the sliding groove 8. At this time, when the rain shield 4 is open, the fixing post 7 slides along the inner wall of the limiting groove 16, and causes the bottom end of the plug 11 to slide along the inner wall of the limiting groove 16. Then, after the rain shield 4 is fully opened, the plug 11 is pushed into the inner wall of the front insertion hole 18 by the elastic force of the elastic element 9, so as to fix the position of the rain shield 4 after it is opened, thereby facilitating maintenance personnel to perform maintenance operations and preventing rainwater from splashing into the surface of the components. The top of the rain shield 4 is provided with Multiple drainage channels 5 guide rainwater from their surfaces, which is then drained through drainage holes 6, thereby improving the performance of the cabinet door 1. After maintenance, the cabinet door 1 is closed, and the rain shield 4 is gradually inserted into the inner wall of the storage slot 17. At this time, multiple elastic elements 13 are installed on the inner wall of the moving slot 12. The elastic force of the multiple elastic elements 13 pushes the moving plate 14 down along the inner wall of the moving slot 12, causing the scraper 15 to adhere to the surface of the rain shield 4, thereby scraping the rainwater forward on the surface of the rain shield 4. After the rain shield 4 is fully reset, the elastic force of the first elastic element 9 pushes the plug 11 into the inner wall of the rear insertion hole 18. After the position of the rain shield 4 after closing is fixed, the scraped rainwater is discharged forward through the drainage channels 5 and drained through the drainage holes 6, thereby reducing the amount of rainwater remaining on the surface of the rain shield 4 for subsequent maintenance.
