[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a factory-fabricated, compact indoor and outdoor power distribution system that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment according to a specific wiring scheme. It organically combines the functions of transformer step-down and low-voltage power distribution within a fully enclosed, removable steel structure that is moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, and heat-insulated. It is particularly suitable for urban power grid construction and renovation, and represents a new type of substation that has emerged after the civil substation. Box-type substations are suitable for mines, factories, enterprises, oil and gas fields, and wind power stations. They replace existing civil power distribution rooms and substations, becoming a new type of complete power transformation and distribution system.

[0003] The bottom plate in the existing box-type substation is a fixed component. When installing transformers and electrical equipment, it is usually necessary to use a forklift to transport the transformers and electrical equipment into the box. Multiple auxiliary staff need to be on both sides of their equipment to guide and assist the equipment in placing it in the box. However, as more electrical equipment is placed, the space in the box becomes smaller, resulting in a significant reduction in the observation angle and observation range, which in turn affects the installation speed. Therefore, the applicant has made a useful design and found a solution to the above problem. The technical solution to be introduced below was produced in this context. Summary of the Invention

[0034] Reference example Figures 1 to 6 A box-type substation that is easy to install includes a box body 1, a partition 11 is provided inside the box body 1, and a plurality of chambers 12 are formed. A lifting portion 13 is provided on both sides of the chamber 12, and a stop portion 14 is provided on one side of the lifting portion 13. The lifting portion 13 is provided with a supporting plate 2 that can move forward and backward. The supporting plate 2 is provided with an extension portion 21 and abuts against the side wall of the stop portion 14. The extension portion 21 is provided with a rack portion 22. A plurality of equally spaced rollers 3 are provided on the top of the lifting portion 13 and abut against the supporting plate 2. A driving assembly 4 is provided at the bottom of the chamber 12 and engages with the rack portion 22. A lifting support assembly 5 is provided on both sides of the front end of the supporting plate 2.

[0035] It is worth mentioning that a first through hole 131 is provided on the side wall of the raised portion 13, baffles 15 are provided on both sides of the entrance of the raised portion 13, and a fixing hole 132 is provided at the front end of the raised portion 13. The first through hole 131 is used to cooperate with the roller 42, and the baffles 15 limit the distance that the supporting plate 2 extends out of the chamber 12;

[0036] It is worth mentioning that the drive assembly 4 includes a drive shaft 41, a roller 42, and a motor 43. The roller 42 is mounted and fixed on the first through hole 131. The drive shaft 41 is pivotally mounted on the roller 42. First driven gears 44 are provided on both sides of the drive shaft 41 and mesh with the rack portion 22. The drive shaft 41 is provided with a second driven gear 45. The motor 43 is mounted and fixed on the bottom of the chamber 12. The rotating shaft of the motor 43 is provided with a driving gear 46 and meshes with the second driven gear 45. The drive shaft 41 is driven to rotate by a motor 43, which reduces the manufacturing cost of the drive assembly 4. The roller 42 reduces the rotation resistance of the drive shaft 41.

[0037] It is worth mentioning that the rear end of the support plate 2 is provided with a limit block 23 on both sides, and the front end of the support plate 2 is provided with a column 24 on both sides. One end of the column 24 is provided with a blind hole 25, and both sides of the blind hole 25 are provided with a limit slot 26. The bottom of the blind hole 25 is provided with a through hole 27. The support plate 2 is provided with a latch 6, which is inserted into the fixing hole 132. The limit block 23 is used in conjunction with the lifting portion 13. The column 24 prevents the spring 52 from detaching. The blind hole 25 limits the distance the support frame 51 can descend. The through hole 27 provides guidance for the guide rod 511. The limit slot 26 prevents the support member from rotating during movement and fixes the orientation of the wheel 53.

[0038] It is worth mentioning that the support assembly 5 includes a support frame 51 and a spring 52. The support frame 51 is provided with a wheel 53. The support frame 51 is provided with a guide rod 511 and passes through the through-hole 27. The end face of the guide rod 511 is provided with a retaining ring 54 and is slidably arranged in the blind hole 25. Both sides of the retaining ring 54 are provided with a protrusion 541 and are slidably arranged in the limit groove 26. The spring 52 is arranged on the outer wall of the cylinder and abuts the supporting plate 2 and the support frame 51. The wheel 53 assists the supporting plate 2 to move forward and backward. When the wheel 53 passes over an uneven ground, the bumps generated are absorbed and reduced by the spring 52, ensuring that the supporting plate 2 has good balance and stability during the movement.

[0039] It is worth mentioning that the chamber 12 is provided with a second through hole 16 corresponding to the support frame 51, and the second through hole 16 is used to accommodate the support frame 51;

[0040] It is worth mentioning that the extension portion 21 is in a vertical relationship with the supporting plate 2, and the rack portion 22 is in a vertical relationship with the extension portion 21. Through the relationship between the above components, the supporting plate 2, the extension portion 21 and the rack portion 22 form a structure that wraps the stop portion 14, thereby preventing the supporting plate 2 from separating from the lifting portion 13.

[0041] The operating principle of the present invention is now described as follows:

[0042] Pull out the pin 6, refer to the attached Figure 4The orientation diagram is shown in FIG. 4 , and the motor 43 is powered to make it run, and drives the driving gear 46 to rotate clockwise, and the driving gear 46 drives the second driven gear 45 to rotate counterclockwise. At the same time, the first driven gear 44 also rotates together, and the first driven gear 44 drives the carrying plate 2 to extend out of the chamber 12. The roller 42 reduces the resistance of the carrying plate 2 during movement, ensuring that the carrying plate 2 moves smoothly until the limit block 23 abuts the baffle 15 and the power supply of the motor 43 is cut off, and the electrical equipment is secured on the carrying plate 2. The spring 52 is squeezed and energy is stored, and then the elastic force released by the spring 52 ensures that the carrying plate 2 and the lifting part 13 are on the same axis, and prevents the box body 1 from being affected by the gravity of the electrical equipment and tilting forward. The motor 43 is powered to make it rotate in the opposite direction, and the carrying plate 2 is stably retracted into the chamber 12 through the wheel 53 and the roller 3, and the latch 6 is inserted into the fixing hole 132 to fix the carrying plate 2 in the position after the movement to prevent the carrying plate 2 from displacement.

[0043] The above design solution can enable the product to achieve the advantage of improving installation efficiency.

[0044] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
