Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, specifically a modular prefabricated substation. Background Technology

[0002] Prefabricated modular substations are integrated substations that are prefabricated, assembled, and commissioned in a factory, and then transported to the site for rapid deployment, either as a whole or in modules. They are characterized by high efficiency, environmental friendliness, and modularity. A prefabricated modular substation is an integrated power facility composed of prefabricated modules, electrical equipment (such as transformers, low-voltage switchgear, and ring main units), and auxiliary facilities (such as air conditioning, fire protection, and monitoring systems). Its core feature is that through factory production, modular design, and rapid on-site assembly, the construction cycle is significantly shortened and construction costs are reduced. In existing technology, patent publication number CN 222029556 U proposes a modular prefabricated modular substation, including a base plate with casters fixedly installed at the four corners of the bottom. A stabilizing component is fixedly installed at the bottom of the base plate, and the substation body is fixedly installed at the top. A ventilation component is fixedly installed on the left side of the substation body. The electrical equipment inside the prefabricated module is mostly connected through pre-drilled mounting holes. Although this reduces the time required for on-site installation, the fixed installation position of the electrical equipment inside the prefabricated module makes it inconvenient to adjust it on-site as needed. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular prefabricated substation, including a base, a prefabricated cabin is provided on the outer edge of the upper surface of the base, an integrated shell is provided inside the prefabricated cabin, and a transformer equipment is provided inside the integrated shell, and a modular installation mechanism is also included. Modular installation mechanism: It includes supports, guide columns, connecting plates, fixed limiting blocks, movable limiting blocks, and mounting plates. The supports are respectively set at the front and rear ends of the upper surface of the base. Guide columns are provided between two supports in the longitudinal position. The integrated shell is respectively set on the upper surface of the mounting plate. Connecting plates are provided at the front and rear ends of the lower surface of the mounting plate. Fixed limiting blocks are provided at the left end of the lower surface of the connecting plates, and adjustable movable limiting blocks are provided at the right end of the lower surface of the connecting plates.

The integrated shell adopts modular installation, which facilitates the adjustment of the installation position of the integrated shell, making it easier to adjust the installation position and increase or decrease the quantity of equipment inside the prefabricated cabin substation.

[0005] Furthermore, the modular installation mechanism also includes positioning holes and positioning pins. The positioning holes are respectively set on the outer arc surface of the guide pin, and the positioning pins are respectively set in the middle of the inner arc surface of the fixed limiting block arc groove and the middle of the inner arc surface of the movable limiting block arc groove.

[0006] Furthermore, each of the lower surfaces of the connecting plate is provided with a sliding groove on the right end, and a screw is rotatably connected between the left and right inner walls of the sliding groove. The screw is threadedly connected to the screw hole at the upper end of the movable limiting block, and the movable limiting block is slidably connected to the inside of the sliding groove to adjust the position of the movable limiting block.

[0007] Furthermore, rollers are rotatably connected between the front and rear inner walls of the rotating grooves on the lower surfaces of the fixed and movable limiting blocks via rotating shafts. The outer arc surfaces of the rollers are in contact with the upper surface of the base, reducing the frictional force experienced by the fixed and movable limiting blocks as they slide on the upper surface of the base.

[0008] Furthermore, the outer arc surface of the connecting column of the guide column is provided with insert plates, and the surface of the vertical plate of the support is provided with slots that cooperate with the insert plates for installation, thereby limiting the installation angle of the guide column and ensuring that the positioning holes are installed horizontally.

[0009] Furthermore, each of the guide posts has a scale plate in the mounting groove on its outer arc surface to facilitate the determination of the mounting plate's installation position.

[0010] Furthermore, corrugated pipes are provided between the movable limiting block and the left and right inner walls of the connecting plate groove, and the corrugated pipes are respectively movably sleeved on the outer arc surface of the screw to provide protection for the screw.

Detailed Implementation

[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] Please see Figure 1-4 This embodiment provides a technical solution: a modular prefabricated substation, including a base 1, which provides support for the installation of the substation. The upper surface of the base 1 is provided with a prefabricated cabin 2, which provides protection for the power equipment. The interior of the prefabricated cabin 2 is provided with an integrated shell 3, which provides space for the integrated installation of primary and secondary power equipment. The interior of the integrated shell 3 is provided with power equipment 11, which includes primary equipment such as transformers, circuit breakers, disconnect switches and instrument transformers, and secondary equipment such as control cables and micro control devices, which perform power transformation control. It also includes a modular installation mechanism 4. Modular installation mechanism 4: It includes a support 41, guide column 42, connecting plate 43, fixed limiting block 44, movable limiting block 45, and mounting plate 48. The support 41 is respectively set at the front and rear ends of the upper surface of the base 1. A guide column 42 is provided between each pair of supports 41 in the longitudinal position. The integrated shell 3 is respectively set on the upper surface of the mounting plate 48. A connecting plate 43 is provided at both the front and rear ends of the lower surface of the mounting plate 48. A fixed limiting block 44 is provided at the left end of the lower surface of the connecting plate 43, and an adjustable movable limiting block 45 is provided at the right end of the lower surface of the connecting plate 43. The fixed limiting block 44 and the movable limiting block 45 are installed in conjunction with the guide column 42. The mounting plate 48 is adjusted in the prefabricated cabin according to the different installation positions required for the primary and secondary power equipment. After adjusting the position within 2, the movable limiting block 45 is moved to the left, reducing the distance between the fixed limiting block 44 and the movable limiting block 45 until the inner arc surfaces of the arc grooves of the fixed limiting block 44 and the movable limiting block 45 are respectively in contact with the outer arc surfaces of the adjacent guide posts 42, thus restricting the left-right and up-down positions of the mounting plate 48. The modular installation mechanism 4 also includes positioning holes 46 and positioning pins 47. The positioning holes 46 are respectively set on the outer arc surfaces of the guide posts 42, and the positioning pins 47 are respectively set in the middle of the inner arc surfaces of the arc grooves of the fixed limiting block 44 and the movable limiting block 45. The positioning pins 47 are installed in conjunction with the positioning holes 46. When the inner arc surfaces of the arc grooves of the fixed limiting block 44 and the movable limiting block 45 are respectively in contact with the outer arc surfaces of the adjacent guide posts 42, the positioning pins 47 are installed in conjunction with the positioning holes 46. When the outer arc surfaces are fitted, the positioning pins 47 are inserted into the adjacent positioning holes 46 to restrict the front and rear positions of the mounting plate 48. The lower right end of the connecting plate 43 is provided with a sliding groove. A screw 5 is rotatably connected between the left and right inner walls of the sliding groove. The screw 5 is threadedly connected to the screw hole at the upper end of the movable limit block 45. The movable limit block 45 is slidably connected laterally inside the sliding groove. The right end of the screw 5 protrudes from the sliding groove and is provided with a knob. Rotating the knob at the right end of the screw 5, through the threaded connection between the screw 5 and the movable limit block 45, causes the movable limit block 45 to move to the left within the sliding groove. Rollers 6 are rotatably connected between the front and rear inner walls of the rotating grooves on the lower surfaces of the fixed limit block 44 and the movable limit block 45 via rotating shafts. The outer arc surfaces of the rollers 6 are in contact with the upper surface of the base 1. By the relative rolling of the roller 6 and the base 1, the friction force experienced by the fixed limiting block 44 and the movable limiting block 45 during sliding adjustment on the upper surface of the base 1 is reduced. The outer arc surface of the connecting column of the guide column 42 is provided with insert plates 7, and the vertical plate surface of the support 41 is provided with slots 8 that cooperate with the insert plates 7 for installation. By inserting the insert plates 7 into the slots 8, the installation angle of the guide column 42 is limited, ensuring that the positioning insertion hole 46 is in a horizontal state. The mounting groove of the outer arc surface of the guide column 42 is provided with scale plates 9. By using the scale corresponding to the connecting plate 43 on the scale plate 9, the installation position of the mounting plate 48 can be quickly determined. Corrugated tubes 10 are provided between the left and right inner walls of the sliding groove of the movable limiting block 45 and the connecting plate 43. The corrugated tubes 10 are movably sleeved on the outer arc surface of the screw 5.During the movement of the movable limit block 45, the bellows 10 extends and retracts, always moving and fitting around the outer arc surface of the screw 5, providing protection for the screw 5.

[0016] The working principle of the modular prefabricated substation provided by this utility model is as follows: During the installation of the prefabricated substation, the position of the mounting plate 48 in the prefabricated cabin 2 is adjusted according to the different installation positions of the primary and secondary power equipment. After adjustment, the rollers 6 are in contact with the upper surface of the base 1, restricting the vertical position of the fixed limiting block 44 and the movable limiting block 45, so that the arc groove of the fixed limiting block 44, the arc groove of the movable limiting block 45 and the guide post 42 are all in the same horizontal plane. By rotating the knob at the right end of the screw 5, the screw 5 is threadedly connected to the movable limiting block 45, causing the movable limiting block 45 to move to the left in the slide groove, and the distance between the fixed limiting block 44 and the movable limiting block 45 is reduced. The arc surfaces of the fixed limiting block 44 and the movable limiting block 45 are aligned with the outer arc surfaces of the adjacent guide posts 42, thus restricting the left-right and up-down positions of the mounting plate 48. At the same time, the positioning pin 47 is inserted into the adjacent positioning hole 46 to restrict the front-back position of the mounting plate 48, quickly fixing the position of the mounting plate 48. Then, the primary and secondary power equipment are installed inside the integrated housing 3. When it is necessary to add equipment or change the installation position of the equipment later, simply rotate the screw 5 in the reverse direction to release the limiting of the mounting plate 48, and the position of the mounting plate 48 can be adjusted. In use, the primary and secondary power equipment inside the integrated housing 3 are used to transform the current.

[0017] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
