Technical Field
[0001] This utility model relates to the field of cabinet interlocking, and more specifically, it also relates to a mechanical interlocking structure. Background Technology
[0002] The safe operation of power distribution systems is a crucial aspect of ensuring power supply. With continuous technological advancements, power distribution systems are gradually evolving towards intelligence and efficiency, with multiple distribution cabinets working together to achieve power distribution control becoming the mainstream configuration. However, existing power distribution systems have significant shortcomings in the design of distribution cabinet enclosures and cabinet door controls. These deficiencies directly lead to serious safety hazards during the operation of the power distribution system.
[0003] In existing power distribution systems, the enclosures of distribution cabinets are designed as independent structures, with each cabinet's door opening and closing operations being independent and unrelated. This design makes it highly susceptible to other distribution cabinets being opened arbitrarily when the power supply to the distribution system is not turned off. Since distribution cabinets typically contain high-voltage electrical equipment, unauthorized personnel opening them without disconnecting the power could lead to electric shock, short circuits, and other safety accidents, posing a serious threat to the personal safety of operators and potentially affecting the stable operation of the power distribution system.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example: like Figures 1 to 9 As shown, this utility model provides a technical solution: a mechanical interlocking structure for mechanically interlocking the cabinet door of the first cabinet 3 with the cabinet door of the second cabinet 4. The cabinet door of the second cabinet 4 can only be opened when the cabinet door of the first cabinet 3 is open, and if the cabinet door of the first cabinet 3 is closed first, the cabinet door of the second cabinet 4 will not be able to be closed. Both the cabinet doors of the first cabinet 3 and the second cabinet 4 are provided with observation windows 13. The observation windows 13 are used to observe the working status of the electronic components inside the cabinet.
[0016] The first cabinet 3 is the power control cabinet, and the second cabinet 4 is the control system cabinet. The first cabinet 3 mainly supplies power to the control components inside the second cabinet 4.
[0017] A mechanical interlocking structure includes: a turntable 1 rotatably disposed within a first cabinet 3; a bracket 7 is fixedly connected within the first cabinet 3; the turntable 1 is rotatably disposed on the bracket 7; the bracket 7 is provided with a positioning part 701; the positioning part 701 has multiple positioning holes in the height direction, one of which is fitted with one end of a tension spring 8 (different positioning holes are selected to adjust the tension of the tension spring 8); the other end of the tension spring 8 is connected to a door bolt 2 (also with different hole positions to adjust the tension of the tension spring 8). The tension spring 8 can drive the door bolt 2 to move horizontally, thereby driving the turntable 1 back to its initial position.
[0018] Turntable 1 is eccentrically hinged to one end of a bolt 2, the other end of which extends into the second cabinet 4. The second cabinet 4 has a slot 401 that mates with the bolt 2. The cabinet door of the first cabinet 3 is fixedly connected to a first baffle 5, and the cabinet door of the second cabinet 4 is fixedly connected to a second baffle 6 that mates with the bolt 2. When the cabinet door of the second cabinet 3 is closed, the second baffle 6 should be positioned below the bolt 2.
[0019] The turntable 1 is provided with a blocking part 101 that cooperates with the first baffle 5. When the blocking part 101 of the turntable 1 contacts the first baffle 5, the bolt 2 passes through the slot 401 and contacts the second baffle 6.
[0020] The turntable 1 is provided with a contact part. When the blocking part 101 of the first baffle 5 moves upward and does not contact the turntable 1, the tension spring 8 will drive the turntable 1 to rotate in the opposite direction and drive the contact part of the turntable 1 to contact the lower surface of the positioning part 701 of the bracket 7. The positioning part 701 limits the turntable 1.
[0021] The bolt 2 is provided with a limiting part that cooperates with the second cabinet 4. When the bolt 2 moves toward the second baffle 6, the limiting part abuts against the second cabinet 4, thereby preventing the bolt 2 from continuing to move into the second cabinet 4.
[0022] The stop part 101 is provided with a contact surface, and the contact surface is provided with a first contact point 1011 and a second contact point 1012 that cooperate with the first baffle 5. The distance between the first contact point 1011 and the rotation center of the turntable 1 is less than the distance between the second contact point 1012 and the rotation center of the turntable 1.
[0023] During the downward movement of the first baffle 5, it will first contact the first contact point 1011, and then move along the contact surface to the second contact point 1012. At this time, the turntable 1 will also rotate, driving the door bolt 2 to move towards the second cabinet 4 and limiting the movement of the second baffle 6. At this time, the second baffle 6 is below the door bolt 2, restricting the upward movement of the cabinet door of the second cabinet 4.
[0024] Both the cabinet doors of the first cabinet 3 and the cabinet doors of the second cabinet 4 are equipped with sealing plates 10 at their bottoms. During the upward movement of the cabinet doors of the first cabinet 3 and the second cabinet 4, sealing plates 10 are installed at the bottom of the cabinet doors to prevent the bottom from being exposed. The sealing plates 10 seal the area where the cabinet doors move upward, reducing the phenomenon of the interior of the cabinet being exposed.
[0025] Both the first cabinet 3 and the second cabinet 4 are provided with multiple hooks 11. The multiple hooks 11 are all located at the junction of the cabinet and the cabinet door, and the hooks 11 are arranged along the height direction of the cabinet. The cabinet door of the first cabinet 3 and the cabinet door of the second cabinet 4 are provided with hanging grooves 12 that cooperate with the hooks 11.
[0026] like Figures 1 to 9 As shown, during operation, when it is necessary to inspect or repair the components inside the second cabinet 4, the cabinet door of the first cabinet 3 is driven upward and disengaged from the hook 11. During the upward movement of the cabinet door of the first cabinet 3, the first baffle 5 is driven to disengage from the turntable 1. At this time, the turntable 1 rotates under the action of the tension spring 8, and the contact part of the turntable 1 contacts the positioning part 701 of the bracket 7, and the turntable 1 stops rotating.
[0027] The cabinet door of the first cabinet is opened (the cabinet door of the first cabinet adopts the conventional cabinet door opening method). After the cabinet door of the first cabinet 3 is opened, the power is turned off. Then the cabinet door of the second cabinet 4 is opened, and the control components inside the second cabinet 4 are tested and repaired.
[0028] After the components in the second cabinet 4 have been inspected and repaired, the cabinet door of the second cabinet 4 is closed first. After the second cabinet 4 is closed, the power supply in the first cabinet 3 is turned on manually, and the cabinet door of the first cabinet 3 is closed and locked. During the downward movement of the first cabinet 3, the first baffle 5 contacts the blocking part 101 of the turntable 1. The blocking part 101 is provided with a contact surface, and the contact surface is provided with a first contact point 1011 and a second contact point 1012 that cooperate with the first baffle 5.
[0029] During the downward movement of the first baffle 5, it will first contact the first contact point 1011, and then move along the contact surface to the second contact point 1012. At this time, the turntable 1 will also rotate, driving the door bolt 2 to move towards the second cabinet 4, and limiting the second baffle 6, so as to realize the mechanical interlock between the cabinet door of the first cabinet 3 and the cabinet door of the second cabinet 4.
[0030] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
