[0036] Example 1

[0037] like Figure 1 and Figure 2As shown, this embodiment provides a box-type intelligent power distribution cabinet for a substation, comprising a cabinet body 1 and a foldable cabinet door. An opening is provided at one end of the cabinet body 1. The foldable cabinet door can be rotatably fixed to the end of the cabinet body 1 away from the ground and covered over the opening. The foldable cabinet door matches the shape of the opening.

[0038] The foldable cabinet door comprises an upper cover 2, a middle cover 3 and a lower cover 4 which are rotatably connected in sequence. The end of the upper cover 2 away from the middle cover 3 is rotatably fixed on the cabinet body 1, and the upper cover 2 rotates toward the side away from the cabinet body 1.

[0039] Working principle: When the cabinet body 1 needs to be opened, the foldable cabinet door is rotated upward. During the rotation process, the middle cover 3 is rotated upward so that the outer side of the middle cover 3 fits with the outer side of the upper cover 2, and the lower cover 4 is rotated in the opposite direction so that the inner side of the lower cover 4 fits with the inner side of the middle cover 3, so that the three sections of cover are folded into one section of cover, which reduces the rotation radius of the cabinet door, makes it convenient to rotate the cabinet door to the cabinet body 1, and also facilitates subsequent manual operations.

[0040] By configuring the foldable cabinet door as an upper cover 2, a middle cover 3, and a lower cover 4, a three-stage folding effect can be achieved, thereby reducing the rotation radius of the door cover and allowing the cabinet door to be easily rotated to the upper end of the cabinet body 1, which is more convenient for small spaces. Compared to cabinet doors that open to both sides, the cabinet door of this solution can be completely folded to the upper end of the cabinet body 1, without obstructing personnel's work inside the cabinet body 1, thereby improving personnel's work convenience and efficiency.

[0041] Preferred embodiment, as Figures 3 to 5 As shown, a connecting rod 7 and a rotating shaft 8 are provided between the middle cover 3 and the lower cover 4. The rotating shaft 8 includes a first rotating shaft and a second rotating shaft. The first rotating shaft is fixed to one end of the middle cover 3 close to the lower cover 4, and the second rotating shaft is fixed to one end of the lower cover 4 close to the middle cover 3. One end of the connecting rod 7 can be rotatably connected to the first rotating shaft, and the other end can be rotatably connected to the second rotating shaft.

[0042] Furthermore, side walls are provided on both sides of the middle cover 3 and the lower cover 4 , and adjacent ends of the side walls of the middle cover 3 and the lower cover 4 are provided with rounded corners 9 , which are coaxially arranged with the rotating shaft 8 .

[0043] The middle cover and the lower cover are connected by a rotating shaft and a connecting rod so that the middle cover and the lower cover can rotate relative to each other, and coaxial fillets are provided adjacent to the side walls of the middle cover and the lower cover so that the middle cover and the lower cover will not interfere with each other due to the right-angled edges of the side walls, so that the lower cover can rotate toward the inside of the middle cover, reducing the volume of the cabinet door after folding and improving the stability of the foldable cabinet door after folding.

[0044] Specifically, the upper cover 2 and the middle cover 3 are rotatably connected via a first hinge, which is located on a side of the middle cover 3 away from the cabinet body 1 , and the upper cover 2 is rotatably fixed to the upper end of the cabinet body 1 via a second hinge.

[0045] The number of the first hinges and the number of the second hinges are both 2, the two first hinges are evenly distributed between the upper cover 2 and the middle cover 3, and the two second hinges are evenly distributed between the upper cover 2 and the cabinet body 1.

[0046] In a preferred embodiment, a hanger 5 and a bottom plate 103 are provided inside the cabinet 1. The hanger 5 can be detachably fixed to the inner wall of the cabinet 1. The hanger 5 is provided with strip-shaped fixing holes 501 for fixing electrical equipment. The bottom plate 103 is fixed inside the cabinet 1, suitable for dividing the cabinet into two spaces.

[0047] like Figure 6 As shown, the bracket 5 includes a steel plate 500 , a fixing hole 501 is opened on the steel plate 500 , and mounting holes 502 are provided at both ends of the fixing hole 501 . The diameter of the mounting hole 502 is larger than the width of the fixing hole 501 .

[0048] A connecting column 102 is provided in the cabinet 1 , one end of the connecting column 102 is vertically fixed to the inner wall of the cabinet 1 , and the other end is provided with a threaded hole matching the mounting hole 502 . The steel plate 500 is detachably fixed to the connecting column 102 by screws.

[0049] By providing multiple connecting posts 102 on the inner wall of the cabinet 1 and leaving a gap between the hanger 5 and the inner wall of the cabinet 1, it is convenient to install electrical equipment in the fixing holes 501 on the steel plate 500. Two connecting posts 102 are provided at both ends of the steel plate 500, which match the mounting holes 501 on the steel plate 500 for detachable fixation, facilitating subsequent maintenance and replacement, and reducing costs. The bottom plate 103 separates a space at the bottom of the cabinet 1, thereby achieving the effect of installing electrical equipment.

[0050] Among them, such as Figure 2 As shown, there are multiple racks 5, and four are provided in this embodiment. The number of racks 5 is adaptively adjusted according to the space and the number of electrical equipment to be fixed. The racks 5 are parallel to each other and are distributed at equal intervals inside the cabinet 1.

[0051] like Figure 7 As shown, the cabinet body 1 includes a cabinet shell 100 with an opening at one end, a ring-shaped protruding plate 101 is provided on one side of the open end of the cabinet shell 100, and a ring-shaped side panel is provided around the foldable cabinet door. The protruding plate 101 is located on the inner side of the side panel, and a rubber strip is provided on the side of the protruding plate 101 close to the side panel.

[0052] By providing a convex plate 101 around the open end of the cabinet body 1, cooperating with the side panels provided around the foldable cabinet door, and further providing a sealing rubber strip between the convex plate 101 and the side panels, the sealing and connection reliability between the cabinet door and the cabinet body 1 are improved.

[0053] In combination with the above preferred implementations, this embodiment provides a more specific working principle of the intelligent distribution cabinet of a box-type substation:

[0054] The cabinet door of the cabinet body 1 can achieve a three-section folding effect through the upper cover 2, the middle cover 3 and the lower cover 4, thereby reducing the rotation radius of the door cover. Since the middle cover 3 rotates toward the outside of the cabinet body 1 and the lower cover 4 rotates toward the inside of the cabinet body 1, interference with the side of the door can be avoided.

[0055] The bracket 5 in the cabinet 1 can be used to install electrical equipment, so that the interior can be protected by the cabinet 1. The rotating shaft 8 can connect the middle cover 3 and the lower cover 4 so that the two can rotate with each other. The opening of the rounded corner 9 can prevent the middle cover 3 and the lower cover 4 from interfering with the right-angled edges, so that the two can rotate normally. The fixing holes 501 opened on the steel plate 500 can be used to fix electrical equipment, and the steel plate 500 can be fixed in the cabinet 1 through the installation holes 502. The outer wall of the protruding plate 101 can be used to install rubber strips, so that the cabinet door can play a sealing role. The connecting column 102 can fix the steel plate 500, and the bottom plate 103 separates a space from the bottom of the cabinet 1, so that electrical equipment can be installed.

[0056] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
