Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated cabins, and in particular to a prefabricated cabin and a bracket structure thereof. Background Art

[0002] With the rapid development of power grids, new intelligent prefabricated cabin substations have been widely promoted and applied in China. The prefabricated cabin includes a cabin, a rack installed in the cabin, and electrical devices installed on the rack. The overall performance of the cabin and the rack installed in the cabin directly affects the safe operation of the substation.

[0003] In the prior art, the Chinese patent document with publication number CN110739608B proposes that the electrical device is fixed to the front mounting part. When the electrical device needs to be wired or repaired, the bracket structure is first pushed and pulled relative to the frame to a set position, and then the front mounting part is flipped downward so that the wiring terminal of the electrical device is above the front mounting part, and then the wiring or maintenance operation is performed. After the wiring or maintenance operation is completed, the front mounting part is flipped and reset, and then the bracket structure is pushed back to the set position of the frame. There is no need to reserve maintenance space between the side wall of the cabin and the rack, and the rack can be placed on the side wall of the cabin, which reduces the size of the cabin and the number of cabins, reduces the area occupied by the prefabricated cabin, and reduces the cost. This solves the problem that the rack in the prefabricated cabin in the prior art cannot be arranged against the side wall of the cabin, resulting in a large area occupied by the prefabricated cabin and high cost, and provides strong support for the development and application of smart substations. However, consistent with the traditional method, the traditional prefabricated cabin requires staff to manually open the door and move the internal components for maintenance. The whole process is cumbersome and error-prone, which seriously affects work efficiency. When performing maintenance or operation, it is necessary to manually adjust the position of multiple components, which consumes a lot of time and effort. In addition, the design of the traditional prefabricated cabin usually makes it difficult to repair or install the components or electronic control components close to the inside. Due to the narrow internal space, the operator must enter the narrow space when performing maintenance, and may even need to disassemble the components on the outside to access the components on the inside, which not only increases the difficulty of operation, but also may cause accidental damage to other components. Therefore, the present application discloses a prefabricated cabin and its bracket structure to meet the convenience of subsequent installation or maintenance inside the prefabricated cabin.

[0018] Beneficial effects of the present invention:

[0019] 1. The prefabricated cabin and its bracket structure are provided with a lifting door, a lifting assembly, a bracket body and a pushing groove for coordinated use. The lifting door can move up and down in the positioning slide groove under the drive of the lifting assembly. By rotating the first adjusting wheel, the rotating rod and the screw rod are driven to rotate, and the positioning slider is driven to move along the positioning slide groove, so as to realize the up and down movement of the lifting door. The staff can move the lifting door to the required position for maintenance or operation, which simplifies the operation process and improves the work efficiency. During the movement of the lifting door, the guard plate will be lifted up and follow the adjustment angle to avoid affecting the movement of the lifting door. When the lifting door is reset, the guard plate is reset under the action of the torsion spring to provide protection and coverage, ensuring the safety and cleanliness of the equipment. During the rising process of the lifting door, the universal ball first contacts the expansion groove on the bracket body, gradually enters the Z-shaped pushing groove, and drives the bracket body to slide outward. The bracket body slides in the T-shaped slide groove through the T-shaped slider to ensure the positioning and stability during the sliding process and maintain the balance. Multiple bracket bodies slide out in sequence, which is convenient for the staff to inspect or connect wires.

[0020] 2. This prefabricated cabin and its bracket structure are provided with an alternating component. By rotating the second adjusting wheel, the belt is driven to move, thereby driving the two slides to move synchronously or in reverse, so that the first slide is driven to move to the front and the lifting plate is moved to the bottom at the rear. In this way, the front and rear position relationship can be adjusted to facilitate installation or maintenance, etc., and this mechanism enables the lifting plate to evenly compress the damper during sliding, providing an effective shock absorbing effect, ensuring the smoothness of movement and the accuracy of positioning. In addition, the positioning block and the V-shaped groove, together with the rotating slider on the lifting plate, realize stable lifting control, avoid the violent vibration and error of the traditional sliding device, and improve the convenience and accuracy of operation. It not only improves the overall stability of the system, but also reduces the inconvenience of operation caused by vibration or error, ensuring that the slide plate can move smoothly to the required position during maintenance or wiring, greatly improving the efficiency and safety of operation.

[0021] 3. This type of prefabricated cabin and its bracket structure, by providing a positioning assembly, achieves accurate positioning by pressing down under its own weight without the need for additional mechanical force, and at the same time achieves deceleration and shock absorption through the cooperation of the support rod and the return spring, protecting the parts from impact and vibration, thereby maintaining quality and integrity. The linkage mechanism connecting the slider and the movable clamp ensures the stable clamping and precise positioning of the parts or electrical components, and the sliding positioning of the first positioning plate and the second positioning plate in the positioning groove provides additional support and stability, so that the positioning assembly can adapt to parts or electrical components of different sizes, providing high flexibility and adaptability, and no complicated mechanical adjustments or changes are required.

[0042] The staff rotates the first adjusting wheel 8 to drive the rotating rod 7 to rotate. The first bevel gears 9 set on both sides of the rotating rod 7 are meshed with the second bevel gear 11 at the bottom of the screw rod 10, so that the screw rod 10 rotates vertically. The rotation of the screw rod 10 drives the positioning slider 12 to move up and down along the positioning slide groove 5. The middle part of the positioning slider 12 is provided with a threaded groove 13 adapted to the screw rod 10, so that the lifting door 6 moves up and down under the drive of the positioning slider 12. After the lifting door 6 moves to the required position, the staff can perform maintenance operations. In the process of the lifting door 6 moving upward, the guard plate 4 is lifted up, and the guard plate 4 follows the rotation to adjust the angle, which will not affect the up and down movement of the lifting door 6.
