Description

Technical Field

[0001] This utility model relates to the field of prefabricated transformer box technology, and in particular to a modular design prefabricated transformer box assembly mechanism. Background Technology

[0002] Prefabricated substations are factory-prefabricated, modular electrical equipment that integrates components such as transformers, switchgear, and protection devices. They are quick to install on-site, easy to operate, and suitable for various outdoor power distribution applications, effectively improving the efficiency and reliability of power grid construction.

[0003] Traditional transformer box assembly technology generally uses welding to fix the box structure. The disadvantages of this method are that the overall size of the transformer box is large, which is not conducive to flexible transportation and handling. Due to the welding fixation, the operation of the box during installation and disassembly is complicated, time-consuming and labor-intensive. This not only increases the cost of installation and maintenance, but also makes it particularly inconvenient when repairs or replacement of parts are needed. In addition, the internal space of traditional transformer boxes is usually a fixed structure, which lacks flexibility. This limits the applicability of transformer boxes and makes it difficult for them to adapt to the diversity of different scenarios and needs. Utility Model Content

[0004] One objective of this invention is to propose a modular design for prefabricated transformer box assembly. This invention addresses the shortcomings of traditional transformer box assembly techniques, which typically employ welding to fix the box structure. The disadvantages of this method include a large overall size of the transformer box, hindering flexible transportation and handling. Furthermore, welding makes installation and disassembly complex, time-consuming, and labor-intensive, increasing installation and maintenance costs and causing significant inconvenience when repairs or component replacements are needed. Additionally, the internal spaces of traditional transformer boxes are usually fixed structures, lacking flexibility and limiting their applicability, making them unsuitable for diverse scenarios and needs.

[0005] A modular prefabricated transformer box assembly mechanism according to an embodiment of the present invention includes:

[0006] A transformer box assembly includes a side panel and a back panel. The side panel and the back panel are spliced ​​together by a connecting groove and a connecting block. A door is rotatably provided on one side of the side panel by a rotating assembly. A canopy and a base are respectively provided at the upper and lower ends of the side panel. The canopy and the base are both connected to the side panel by a disassembly and assembly mechanism. Mounting blocks are symmetrically fixed at the connection ends of the canopy and the base.

[0007] The disassembly and assembly mechanism is installed at both the upper and lower ends of one side panel of the transformer box assembly to enable rapid assembly of the prefabricated transformer box. The mechanism includes a housing, inside which a second spring and a third spring are fixedly installed at the lower end. A first pressing block is fixedly installed on the top of the second spring. The third spring is attached to the tail end of a latch. The latch is rotatably mounted inside the housing. A reset component for latch resetting is installed above the tail end of the latch.

[0008] A compartment division mechanism is installed inside the transformer box assembly to adjust the utilization rate of the space. The compartment division mechanism includes a positioning rod, a sliding plate is slidably arranged on the outer side of the positioning rod, a partition is fixedly arranged between the two sliding plates, and a positioning component is arranged between the bottom and side plate of the partition.

[0009] Preferably, the connecting groove is formed inside the side plate, and the connecting blocks are disposed at both ends of the back plate.

[0010] Preferably, the rotating assembly includes an L-shaped lever, a first spring is fixedly disposed between the two L-shaped levers, and a rotating shaft is fixedly disposed at the end of the L-shaped lever away from the first spring.

[0011] Preferably, an observation window and a first handle are fixedly provided on one side of the box door.

[0012] Preferably, the reset assembly includes a second pressing block, which is movably disposed inside the housing and fits against the upper end of the latch, and a lever is fixedly disposed on one side of the second pressing block.

[0013] Preferably, the positioning rod is movably positioned inside the side plate, and a support plate is fixedly mounted on the top of the positioning rod.

[0014] Preferably, the positioning component includes a fixed seat and a limiting post. The fixed seat is fixedly disposed at the bottom of the partition, and the limiting post is fixedly disposed on the outer side of the side plate. An elastic telescopic rod is fixedly disposed between the two fixed seats. A limiting plate is fixedly disposed at the output end of the elastic telescopic rod. The limiting plate and the limiting post are adapted to each other and are engaged.

[0015] Preferably, a second handle is fixedly provided on one side of the limiting plate.

[0016] The beneficial effects of this utility model are:

[0017] This utility model effectively avoids the problem of complicated operation during the installation and disassembly of the transformer box by setting up the transformer box components and disassembly mechanism. When assembling the pre-installed transformer box, the side plate and back plate are quickly spliced ​​together by the connecting groove and connecting block to form the box. By moving the two L-shaped levers, the rotating shaft is retracted into the box, and then the box door can be quickly spliced ​​with the box. After releasing the L-shaped levers, it is positioned, and then the top and base are installed to the top and bottom ends of the box. The mounting frame set at the connection end of the top and base is inserted into the box set in the disassembly mechanism. The mounting block presses the first pressing block downward, and then the latch loses its pushing force and is locked into the inside of the mounting block under the action of the third spring. Thus, the pre-installed transformer box can be quickly installed. When it is necessary to move and disassemble, the pre-installed transformer box can be quickly disassembled by simply moving the lever and L-shaped lever. Therefore, it effectively solves the problem of complicated installation, time and labor consumption caused by welding and fixing of traditional transformer boxes, and improves the efficiency and flexibility of transformer box use.

[0018] This invention utilizes a compartment division mechanism. When adjusting the internal space of a prefabricated transformer box, pulling the second handle outward causes the limiting block connected to the output end of the elastic telescopic rod to slide outward, disengaging it from the outer side of the limiting post. At this point, the partition can be slid up and down on the outer side of the positioning rod, easily dividing and adjusting the size of the compartments to accommodate the installation requirements of different electrical components. After the space adjustment is complete, releasing the second handle allows the limiting plate to re-engage with the limiting post under the reset action of the elastic telescopic rod, thus achieving the partition positioning effect. This effectively solves the problem of fixed and inflexible internal partition spaces in traditional transformer boxes. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] refer to Figure 1-5 A modular prefabricated transformer box assembly mechanism, comprising:

[0028] The transformer box assembly 1 includes a side plate 101 and a back plate 103. The side plate 101 and the back plate 103 are spliced ​​together by a connecting groove 102 and a connecting block 104. The side plate and the back plate are quickly spliced ​​together by the connecting groove and the connecting block to form a box body. A box door 105 is rotatably provided on one side of the side plate 101 by a rotating assembly. A canopy 111 and a base 112 are respectively provided at the upper and lower ends of the side plate 101. The canopy 111 and the base 112 are both connected to the side plate 101 by a disassembly and assembly mechanism 2. Mounting blocks 113 are symmetrically fixed at the connection ends of the canopy 111 and the base 112.

[0029] The disassembly / assembly mechanism 2 is installed at both the upper and lower ends of one side of the side plate 101 in the transformer box assembly 1, and is used to realize the rapid assembly of the pre-assembled transformer box. The disassembly / assembly mechanism 2 includes a housing 201. A second spring 202 and a third spring are fixedly installed at the lower end of the housing 201. A first pressing block 203 is fixedly installed on the top of the second spring 202. The third spring 205 is attached to the tail end of the latch 204. The latch 204 is rotatably disposed inside the housing 201. A reset assembly for resetting the latch 204 is installed above the tail end of the latch 204. The component includes a second pressing block 206, which is movably disposed inside the housing 201 and fits against the upper end of the latch 204. A lever 207 is fixedly disposed on one side of the second pressing block 206. The top and base are installed to the upper and lower ends of the housing. The mounting frame set at the connection end of the top and base is inserted into the housing provided in the disassembly and assembly mechanism. The mounting block presses the first pressing block downward, and then the latch loses its push-out force and is locked into the interior of the mounting block under the action of the third spring, thereby achieving the effect of rapid installation of the prefabricated transformer box housing.

[0030] The compartment division mechanism 3, installed inside the transformer box assembly 1, is used to adjust the utilization rate of the space. The compartment division mechanism 3 includes a positioning rod 301, with a sliding plate 303 slidably mounted on the outer side of the positioning rod 301. A partition 304 is fixedly mounted between two sliding plates 303. A positioning assembly is provided between the bottom of the partition 304 and the side plate 101. The positioning assembly includes a fixing seat 305 and a limiting post 309. The fixing seat 305 is fixedly mounted on the bottom of the partition 304, and the limiting post 309 is fixedly mounted on the outer side of the side plate 101. An elastic telescopic rod 306 is fixedly mounted between two fixing seats 305. A limiting plate 307 is fixedly installed at the output end of the elastic telescopic rod 306. The limiting plate 307 is adapted to the limiting post 309 and is engaged. By pulling the second handle outward, the limiting block connected to the output end of the elastic telescopic rod slides outward to disengage from the outside of the limiting post. At this time, the partition can be slid up and down on the outside of the positioning rod, so that the size of the compartment can be easily divided and adjusted to meet the installation requirements of different electrical components. After the space adjustment is completed, the second handle is released, so that the limiting plate re-engages with the limiting post under the reset action of the elastic telescopic rod, thereby achieving the effect of partition positioning.

[0031] Example 1: The connecting groove 102 is opened inside the side plate 101, the connecting block 104 is set at both ends of the back plate 103, the rotating assembly includes an L-shaped lever 106, a first spring 107 is fixedly set between the two L-shaped levers 106, a rotating shaft 108 is fixedly set at the end of the L-shaped lever 106 away from the first spring 107, an observation window 109 and a first handle 110 are fixedly set on one side of the door 105 respectively, moving the two L-shaped levers causes the rotating shaft to be stored inside the box, at which time the box door can be quickly spliced ​​with the box body, and the L-shaped levers are released to position.

[0032] Example 2: The positioning rod 301 is located inside the side plate 101 and is movable. The top of the positioning rod 301 is fixedly provided with a support plate 302, which can facilitate the quick assembly and disassembly of the compartment division mechanism, so as to facilitate the handling and carrying of the device. A second handle 308 is fixedly provided on one side of the limiting plate 307.

[0033] Working principle: First, the transformer box assembly 1 is quickly assembled with the connecting block 104 via the connecting groove 102 between the side plate 101 and the back plate 103 to form the box body. The box door 105 is rotatably mounted on one side of the side plate 101 via a rotating assembly (including an L-shaped lever 106 and a first spring 107) for easy opening and closing. The roof 111 and the base 112 are connected to the side plate 101 via a disassembly and assembly mechanism 2. The disassembly and assembly mechanism 2 includes a housing 201, a second spring 202, a third spring 205, a latch 204, and a reset assembly (including a second pressing block 206 and a lever 207). During assembly, the mounting blocks 113 of the roof and base are inserted into the housing 201 of the disassembly and assembly mechanism. By pressing the first pressing block 203, the latch 204 is engaged with the third spring 205. Under the action of the mechanism, the compartment division mechanism 3 is engaged with the mounting block to achieve rapid assembly. The compartment division mechanism 3 includes a positioning rod 301, a sliding plate 303, a partition 304, and positioning components (fixed seat 305, limiting post 309, elastic telescopic rod 306, and limiting plate 307). By pulling the second handle 308, the limiting plate 307 is disengaged from the limiting post 309, so that the partition 304 can slide up and down on the outside of the positioning rod 301 to adjust the size of the compartment. By rotating the L-shaped lever 106, the rotating shaft 108 is stored inside the box, and the box door 105 is quickly assembled. The top of the positioning rod 301 is provided with a support plate 302, which facilitates the quick disassembly and assembly of the compartment division mechanism, and is convenient for handling and carrying. This improves the assembly efficiency and space utilization of the transformer box and adapts to the installation requirements of different electrical components.
