Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power distribution cabinet installation, in particular to a power distribution cabinet top cover which is convenient for installation and maintenance. Background Art
[0002] The top cover of the traditional power distribution cabinet often adopts a fastening structure of a cover plate and self-tapping screws. The cover plate is fixed to the top of the power distribution cabinet by self-tapping screws, but the self-tapping screws cannot be disassembled multiple times, otherwise the fastening effect of the self-tapping screws will be significantly reduced. Therefore, the traditional power distribution cabinet fails to fully consider the convenience of the early installation and later maintenance of the horizontal busbar copper bar on its top. At the same time, the sealing structure on the top of the power distribution cabinet is not conducive to the outflow of internal hot air, and the heat dissipation performance of the power distribution cabinet needs to be improved. Utility Model Content
[0003] In order to facilitate the installation and subsequent maintenance of the horizontal busbar copper bar on the top of the power distribution cabinet, the utility model provides a power distribution cabinet top cover that is easy to install and maintain. When installation or maintenance work is required, the top cover can be flipped backwards for operation, and the top cover can be closed after the operation is completed. The power distribution cabinet top cover has the characteristics of convenient installation, simple maintenance, enhanced heat dissipation and high structural strength.
[0004] This application provides the following technical solutions:
[0005] The four sides of the top cover of the power distribution cabinet are vertically bent to form a front vertical bending surface, a left vertical bending surface, a right vertical bending surface and a rear vertical bending surface, wherein the lower end of the front vertical bending surface is bent 90 degrees to form a front horizontal bending surface, an array of through holes is provided on the front horizontal bending surface, and the front horizontal bending surface is connected to the cabinet body of the power distribution cabinet by rivet bolts, and the rear vertical bending surface is provided with an array of through holes for installing hinges, and the rear vertical bending surface is connected to the cabinet body of the power distribution cabinet by hinges.
[0006] Technical principle: The top cover of the distribution cabinet is fixed to the top of the distribution cabinet through the rear hinge and the front rivet bolts. When the rivet fixing bolts are removed, the top cover forms a semi-movable connection with the cabinet body and can be easily flipped backwards. The top cover can be fixed again by restoring the bolts.
[0007] Beneficial effect: When the installer needs to work, remove the rivet fixing bolts and flip the top cover backward to form a working space; after the work is completed, restore the fixing bolts to fix the top cover of the distribution cabinet, which is convenient and quick.
[0008] Furthermore, the rear vertical bending surface is connected to the cabinet body of the power distribution cabinet through two hinges.
[0009] Beneficial effect: Using two hinges to connect the top cover and the cabinet body of the power distribution cabinet can ensure reliable connection and smooth turning process.
[0010] Furthermore, the front vertical bending surface and the rear vertical bending surface are respectively provided with array-distributed notches.
[0011] Beneficial effect: The front vertical bending surface is opposite to the rear vertical bending surface, and the array slots formed therein form a convection channel, which facilitates the outflow of internal hot air.
[0012] Furthermore, the two ends of the left vertical bending surface are bent inward at 90 degrees to form a first overlapping surface with the front vertical bending surface and a second overlapping surface with the rear vertical bending surface; the two ends of the right vertical bending surface are bent inward at 90 degrees to form a third overlapping surface with the front vertical bending surface and a fourth overlapping surface with the rear vertical bending surface, and through holes are provided in the parts where the front vertical bending surface and the rear vertical bending surface overlap with the overlapping surfaces for installing self-tapping screws.
[0013] Beneficial effects: The vertical bending surfaces on both sides of the top cover of the distribution cabinet are bent 90 degrees at both ends to form overlapping surfaces with the front vertical bending surfaces and the rear bending surfaces. Openings are set on the overlapping surfaces, and the vertical bending surfaces on the sides are fixedly connected with the front and rear vertical bending surfaces by self-tapping screws, thereby improving the structural stability of the top cover of the distribution cabinet.
[0014] Furthermore, the material of the top cover of the distribution cabinet is aluminum-zinc plate.
[0015] Beneficial effect: The aluminum-zinc plate material ensures the structural strength and corrosion resistance of the top cover of the distribution cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The lower end of the front vertical bending surface 1 is bent 90 degrees to form a front horizontal bending surface 2. An array through hole 11 is provided on the front horizontal bending surface 2. The front horizontal bending surface 2 can be fixedly connected to the cabinet body of the power distribution cabinet by passing rivet bolts through the array through holes 11. The rear vertical bending surface 5 is provided with a hinge installation through hole, and the rear vertical bending surface 5 is connected to the cabinet body of the power distribution cabinet through two hinges 6. Therefore, the top cover of the power distribution cabinet is fixed to the top of the power distribution cabinet through the rear hinge 6 and the front rivet bolts. The front vertical bending surface 1 and the rear vertical bending surface 5 also have heat dissipation slots 12 with a size of 1mm*30mm and arranged in an array to facilitate the outflow of internal hot air, while ensuring that the protection level of the top cover is not lower than IP4X. The array-arranged slots 12 take into account both the heat dissipation performance and the protection level of the top cover. The specific structure is as follows Figure 1 and Figure 2 shown.
[0025] The material of the top cover of the power distribution cabinet is aluminum-zinc plate, which has high strength and corrosion resistance. In order to improve the structural stability of the top cover of the power distribution cabinet and simplify the number of parts and processing procedures, the two ends of the left vertical bending surface 3 and the right vertical bending surface 4 are bent inward 90 degrees to form the first overlapping surface 7, the second overlapping surface 8, the third overlapping surface 9 and the fourth overlapping surface 10 with the front vertical bending surface and the rear bending surface respectively. Through holes are provided in the parts where the front vertical bending surface and the rear vertical bending surface overlap with the overlapping surface for installing self-tapping screws. Its structure is as follows: Figure 3 The front vertical bending surface 1, the rear vertical bending surface 5, the left vertical bending surface 3, and the right vertical bending surface 4 are fixed by self-tapping screws and overlapping surfaces to ensure the overall structural stability of the top cover.
