[0002] Box-type substation, also called prefabricated substation or prefabricated substation. It is a kind of factory-prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme with high-voltage switchgear, distribution transformer and low-voltage distribution device. It combines transformer step-down, low-voltage distribution and other functions organically and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation.

[0003] According to announcement number CN114530776A, a box-type substation that is easy to maintain includes a box body, a working chamber is opened in the box body, a control chamber is opened on the right inner wall of the working chamber, and a control structure is symmetrically arranged in the control chamber. The control structure is used to control the movement of internal parts, and the control structure includes a pressing plate that is sliding left and right in the control chamber.

[0004] In view of the above description, the applicant believes that there are the following problems: During use, when the equipment is used to maintain power electronic components inside the box-type substation, a challenge that maintenance personnel often face is the management of the box door. Since the current design lacks a stable locking or fixing mechanism, the box door is prone to repeated opening and closing without control when it encounters harsh environmental conditions such as wind and rain. This not only accelerates the wear and damage of the box door structure, but also poses a potential threat to the internal electrical components. In addition, the instability of the box door opening and closing also greatly affects the smooth progress of maintenance work, brings unnecessary troubles and safety hazards to the working environment of technicians, and reduces maintenance efficiency and operational convenience. Summary of the invention

[0005] The object of the present invention is to provide a box-type substation that is easy to maintain, so as to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a box-type substation that is easy to maintain, comprising a substation box and a tool storage box, wherein a box cover is hingedly connected to the front hinge of the substation box, a mounting mechanism is provided on the box cover and the tool storage box, an opening and fixing mechanism is provided on the substation box, and a limit mechanism is provided on the opening and fixing mechanism; The opening and fixing mechanism includes a double-axis motor, which is fixedly connected to the center of the back of the transformer substation box, a cover plate is fixedly connected to the back of the transformer substation box, and the cover plate is arranged on the top of the double-axis motor.

At the same time, when the substation is set up and installed, the box cover will not be opened at will, thereby reducing the power electronic components in the substation from being damaged at will.

[0017] 3. The box-type substation which is easy to maintain drives the fixing seat to move through the spring, and the fixing seat drives the T-shaped connecting rod to move until the fixing seat drives the plug rod to be inserted into the socket slot, and then the square plate is inserted into the square slot again. When the box cover is opened or closed, the position of the box cover will not change arbitrarily.

[0018] 4. The box-type substation which is easy to maintain, drives the tool storage box to insert and slide the T-block in the T-slot, and when the rotating plate is turned on the surface of the rotating rod to rotate until the rotating plate is inserted in the rectangular slot, the fixed plate drives the long block to be inserted in the long slot, and the bolts threadably fix the fixed plate and the box cover, so that the tool storage box can be set up and installed on the inner side of the box cover, which is convenient for maintenance personnel to place maintenance tools in the tool storage box when repairing power electronic components, thereby reducing the situation where tools are placed everywhere and difficult to find.

[0029] In actual operation, when this device is used, when it is necessary to repair the power electronic components in the transformer substation box 1, it is first necessary to start the dual-axis motor 63 to drive the rotating rods 62 at both ends to rotate, and at the same time, the rotating rod 62 drives the second gear 69 to rotate. Since the second gear 69 and the first gear 64 are meshed and connected, and with the cooperation of the rotating seat 61, the first gear 64 can be rotated around the second gear 69 in a circle. When the first gear 64 rotates, it can drive the rotating shaft 601 to rotate, and at the same time, the rotating shaft 601 drives the transmission plate 65 to rotate. When the transmission plate 65 rotates, the T-shaped rotating rod 602 can move forward and backward, so that when the power electronic components are repaired later, the box cover 2 will not rotate and close by itself, reducing the impact of the maintenance operation of the maintenance personnel; When the T-shaped rotating rod 602 moves, the moving plate 606 can be driven to move, and the moving plate 606 drives the slider 605 to slide in the arc-shaped sliding groove 604.

At the same time, when the substation is set up and installed, the box cover 2 will not be opened at will, reducing the power electronic components in the substation from being damaged at will; Under the rebound force of the spring 53, the spring 53 drives the fixing seat 58 to move, and the fixing seat 58 drives the T-shaped connecting rod 55 to move, until the fixing seat 58 drives the insertion rod 52 to be inserted into the insertion slot 51, and the square plate 56 is inserted into the square slot 57 again, so that the box cover 2 will not change position at will when the box cover 2 is opened or closed; When maintenance personnel repair power electronic components, they can first drive the tool storage box 3 to insert and slide the T-block 41 into the T-slot 43. When the rotating plate 402 is turned on the surface of the rotating rod 49 to rotate until the rotating plate 402 is inserted into the rectangular slot 403, the fixed plate 47 drives the long block 48 to be inserted into the long slot 46. The bolts 401 threadably fix the fixed plate 47 and the box cover 2, so that the tool storage box 3 can be set up and installed on the inner side of the box cover 2, so that maintenance personnel can place maintenance tools in the tool storage box 3 when repairing power electronic components, thereby reducing the situation where tools are placed everywhere and difficult to find.
