Specific embodiments
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0026] Refer to Figures 1 - 5 , a low-voltage power cabinet with a double-layer structure, including a cabinet body 1, and a base 19 is installed at the bottom of the cabinet body 1 for elevating and supporting the cabinet body 1, which can prevent the accumulated water on the ground from overflowing over the bottom of the cabinet body 1 and entering the cabinet body 1.
[0027] As Figure 1 shown, a first opening 2 is provided on one side of the cabinet body 1, and a first opening and closing door 3 is hinged on one side of the first opening 2. The other side of the first opening and closing door 3 is connected to the cabinet body 1 through a lock. In the actual use process, a window is provided on the first opening and closing door 3, and a visual glass is installed in the window so as to observe the electrical components in the cabinet body 1 through the visual glass.
[0028] A first support plate 4 is provided on one side of the cabinet body 1 close to the first opening 2. There is a gap between the first support plate 4 and the first opening 2, and one side of the first support plate 4 is fixed to the inner wall of the cabinet body 1, and there is a gap between the other side of the first support plate 4 and the adjacent inner wall of the cabinet body 1 and a second support plate 5 is vertically installed. The second support plate 5 is fixed to the inner wall of the cabinet body 1;
[0029] It should be noted that in the actual use process, as Figure 2 shown, the electronic components are arranged inside the "L"-shaped plate formed by the first support plate 4 and the second support plate 5 and are fixedly supported by connecting brackets.
[0030] AsFigure 4 and Figure 5 As shown in Figure 5 , a second opening 6 is formed in the first support plate 4. Between the gaps between the second support plate 5 and the inner wall of the cabinet 1, there are two strip-shaped seats 12 with one end bent in a "U" shape. The two strip-shaped seats 12 are respectively fixed at the upper and lower ends of the cabinet 1, and the "U"-shaped ends of the strip-shaped seats 12 face the first support plate 4 and are arranged close to it. A chute 13 is correspondingly formed inside the strip-shaped seat 12. A slider 11 is slidably installed in the chute 13. In the actual use process, the front view projection of the slider 11 is circular, that is, the slider 11 is a cylindrical block and can rotate freely in the chute 13;
[0031] A second opening and closing door 7 corresponding to the second opening 6 is arranged between the two sliders 11. A connecting seat 9 is installed on one side of the second opening and closing door 7. Both ends of the connecting seat 9 are installed with connecting shafts 10. The other ends of the connecting shafts 10 are rotatably installed on the sliders 11. The side of the second opening and closing door 7 away from the connecting seat 9 is fixed to the first support plate 4 through a lock. A handle 18 is installed on the side of the second opening and closing door 7 where the raw material connecting seat 9 is located. After unlocking the lock, the handle 18 can be pulled to open the second opening and closing door 7. As the second opening and closing door 7 is opened, the second opening and closing door 7 can be pushed to continue moving along the sliding track of the slider 11 in the chute 13, so as to push the second opening and closing door 7 between the second support plate 5 and the inner wall of the cabinet 1 for storage. At this time, the second opening and closing door 7 will not block the second opening 6 around the second opening 6, that is, when the maintenance personnel stand at the second opening 6 to maintain and repair the electrical components, the second opening and closing door 7 will not obstruct the maintenance personnel.
[0032] Furthermore, limit plates 14 are correspondingly installed on both sides of the top of the chute 13. A gap corresponding to the connecting shaft 10 is left between the two limit plates 14, which can limit the slider 11 in the chute 13 to ensure the stable movement of the slider 11 in the chute 13.
[0033] In order to be able to operate the buttons, indicator lights, and rotary switches on the electrical components after the first opening and closing door 3 is opened, several slots 8 are formed in the second opening and closing door 7, so that after the second opening and closing door 7 is closed, the buttons, indicator lights, and rotary switches on the electrical components can be exposed from the slots 8, which is convenient for the use of some switches and buttons.
[0034] It should be noted that in actual use, the connection brackets for installing electrical components in the power cabinet are mostly made of metal iron sheets, and their support strength is limited. Especially when operating switches on electrical components, it is extremely easy to damage the connection brackets. Therefore, since the end of the chute 13 close to the first support plate 4 is also "U"-shaped like the strip seat 12, when opening the second opening and closing door 7, after unlocking, the second opening and closing door 7 needs to be horizontally pulled outwards. This moving distance corresponds to the insertion length of the buttons, indicator lights, and rotary switches on the electrical components into the slot 8. Therefore, after the second opening and closing door 7 is closed, the inner wall of the slot 8 closely adheres to the sides of the buttons, indicator lights, rotary switches and other structures of the electrical components, providing additional support for these electrical components by relying on the second opening and closing door 7, so that the electrical components have sufficient support when the switch is toggled and will not damage the connection brackets; in addition, an elastic rubber pad 16 is installed inside the slot 8, which can further improve the support effect of the slot 8 on the electrical components.
[0035] It should be further noted that as Figure 1 and Figure 3 shown, ventilation holes 17 are provided on both sides of the cabinet body 1, and at least one fan 15 is installed on the second support plate 5. The fan 15 blows air from the side close to the second support plate 5 towards the first support plate 4. Cooperating with the ventilation holes 17 on both sides, the air can flow from one ventilation hole 17 to the other ventilation hole 17, thereby accelerating the air flow inside the cabinet body 1 and playing a role in dissipating heat from the electronic components inside the cabinet body 1.
[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
