Description

Technical Field

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

[0002] A prefabricated substation is a compact, complete power distribution unit that integrates high-voltage switchgear, distribution transformers, low-voltage switchgear, power metering equipment, reactive power compensation equipment, etc., into one or more enclosures according to a specific wiring scheme. It possesses complete power transformation and distribution functions, enabling the reception, conversion, and distribution of electrical energy to provide power to surrounding users. Using modular prefabricated substations, the entire unit can be divided into multiple prefabricated modules, manufactured in a factory and transported to the site for assembly. Compared to traditional integrated substations, this significantly reduces on-site construction time and workload. Furthermore, in terms of transportation convenience, the small size and light weight of each module make it easier to transport than traditional integrated substations, even in areas with poor transportation conditions such as narrow mountain roads.

[0003] In most cases, existing prefabricated substations are assembled by welding, which is time-consuming and labor-intensive. Moreover, welding is mostly a one-time installation, and when additional installations are needed, it is not possible to effectively splice them together, which ultimately leads to problems that affect installation efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a modular prefabricated substation, which aims to improve the existing technology where prefabricated substations are mostly assembled by welding, which is time-consuming and labor-intensive. Furthermore, since welding is mostly a one-time installation, it is difficult to effectively splice together subsequent installations, thus affecting the installation efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular box-type substation, comprising a connecting plate, a top plate provided on the upper surface of the connecting plate, a partition provided on one side of the outer wall of the connecting plate, a snap-fit ​​assembly for connecting the top plate and the connecting plate installed on the lower surface of the top plate, and a limiting assembly for connecting the partition and the connecting plate installed inside the partition.

[0006] The snap-fit ​​assembly includes a sliding frame, the upper surface of which is fixedly connected to the lower surface of the top plate. A spring is fixedly connected inside the sliding frame, and a snap-fit ​​block is fixedly connected to one end of the spring. A sliding groove is provided inside the top plate, and a sliding column is slidably connected to the inner wall of the sliding groove. One end of the sliding column is fixedly connected to one side of the outer wall of the snap-fit ​​block. A snap-fit ​​groove is provided inside the connecting plate, and the inner wall of the sliding frame is slidably connected to the inner wall of the connecting plate.

[0007] Furthermore, the limiting component includes a third spring, which is fixedly connected inside the partition. A first locking block is fixedly connected to one end of the partition. A second spring is fixedly connected inside the connecting plate. A button is fixedly connected to one end of the second spring, and one end of the button is in contact with one side of the outer wall of the first locking block.

[0008] Furthermore, a support plate is fixedly connected to the lower surface of the connecting plate, and the support plate has an inclined edge design.

[0009] Furthermore, a support foot is fixedly connected to the lower surface of the support plate.

[0010] Furthermore, a mounting plate is fixedly connected to the upper surface of the support plate, and a positioning hole is provided inside the mounting plate.

[0011] Furthermore, a positioning post is fixedly connected to the lower surface of the top plate, and one side of the outer wall of the positioning post is slidably connected to the inside of the positioning hole.

[0012] Furthermore, a side plate is slidably connected to one side of the outer wall of the mounting plate, and a rotating door is rotatably connected to one side of the outer wall of the connecting plate.

[0013] Furthermore, the rotating door has heat dissipation holes inside, which are used to facilitate heat dissipation of the device.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, splicing and installation are achieved by using a snap-fit ​​assembly and a limiting assembly. The sliding column drives the snap-fit ​​block to move and disengage from the sliding frame and the connecting plate, thereby disassembling the top plate and the connecting plate. During installation, simply align and insert the snap-fit ​​block into the slot. Then, the button drives the snap-fit ​​block to disengage from the connecting plate, thereby disassembling the partition. When installing the partition, simply insert it. The above splicing method is simple and quick to operate, solving the problem that welding and installation of box-type substations in the prior art is time-consuming and labor-intensive, and the installation is a one-time process that cannot effectively increase the number of splices, thus affecting the installation efficiency. This improves the practicality of the device.

[0016] 2. In this utility model, by adding a base plate to raise the substation device, the corrosion of the substation by water flow is prevented. Furthermore, the inclined design of the top plate and support plate prevents rainwater from accumulating at the bottom of the substation, thus preventing corrosion. This solves the problem that rainwater accumulates at the bottom of the substation during rainy weather, which can corrode the device over time and affect its moisture-proof performance, thereby improving the practicality of the device.

[0023] 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.

[0024] Reference Figure 1 - Figure 4This utility model provides an embodiment of a modular box-type substation, including a connecting plate 3, which provides a stable mounting plane and support point for a top plate 1, a partition plate 6, and other related components. The top plate 1 is mounted on the upper surface of the connecting plate 3, serving a protective function to prevent external dust, rainwater, foreign objects, etc., from entering the substation interior and protecting the internal electrical equipment from external environmental factors. A partition plate 6 is mounted on one side of the outer wall of the connecting plate 3, mainly used to divide the internal space of the substation into different functional areas. A snap-fit ​​assembly for connecting the top plate 1 to the connecting plate 3 is mounted on the lower surface of the top plate 1. A limiting assembly for connecting the partition plate 6 to the connecting plate 3 is mounted inside the partition plate 6. The snap-fit ​​assembly includes a sliding frame 9, which is fixedly connected to the lower surface of the top plate 1, enabling the snap-fit ​​assembly to be fixedly mounted on the top plate 1 and guiding the sliding column 7 and the second locking block 19 to move in a specific direction. The upper surface of the sliding frame 9 is fixedly connected to the lower surface of the top plate 1, and a spring 8 is fixedly connected inside the sliding frame 9. One end of the spring 8 is fixedly connected to the second locking block 19. During installation, when the sliding... After the bracket 9 is inserted into the slot 11, the second locking block 19 is engaged in the slot 11 under the action of the first spring 8, preventing the top plate 1 from moving vertically, thus firmly fixing the top plate 1 to the connecting plate 3. This provides elasticity to the second locking block 19, giving it a tendency to extend outward in its natural state. The top plate 1 has a sliding groove 10 inside, and a sliding post 7 is slidably connected to the inner wall of the sliding groove 10. One end of the sliding post 7 is fixedly connected to one side of the outer wall of the second locking block 19. The connecting plate 3 has a slot 11 inside, and the inner wall of the sliding bracket 9 is slidably connected to the connecting plate 3. The inner wall of the connecting plate 3 includes a limiting component including a spring 15, which enables the locking block 12 to actively contact the connecting plate 3 and lock into the interior of the connecting plate 3 during the installation of the partition 6. The spring 15 is fixedly connected inside the partition 6. The locking block 12 is fixedly connected to one end of the partition 6. The connecting plate 3 is fixedly connected to a spring 14, which provides elasticity to the button 13, so that the button 13 is tightly fitted to the outer wall of the locking block 12 under normal conditions. The button 13 is fixedly connected to one end of the spring 14, and one end of the button 13 is fitted to one side of the outer wall of the locking block 12.

[0025] Reference Figure 1 and Figure 2A support plate 16 is fixedly connected to the lower surface of the connecting plate 3, providing a certain height for the device and preventing rainwater corrosion from affecting the moisture-proof effect. The support plate 16 has a beveled design so that rainwater will not remain at the bottom of the substation. A support foot 17 is fixedly connected to the lower surface of the support plate 16, and a mounting plate 2 is fixedly connected to the upper surface of the support plate 16. The mounting plate 2 has a positioning hole 20 inside. A positioning post 21 is fixedly connected to the lower surface of the top plate 1. One side of the outer wall of the positioning post 21 is slidably connected to the positioning hole 20. When installing the top plate 1, the positioning post 21 is first inserted. The positioning hole 20 provides initial positioning guidance for the top plate 1, ensuring that the top plate 1 is accurately positioned in the horizontal direction. A side plate 5 is slidably connected to one side of the outer wall of the mounting plate 2. The side plate 5 can effectively block external objects from colliding with and damaging the equipment inside the substation, while preventing dust, rainwater and other impurities from entering the substation from the side. A rotating door 4 is rotatably connected to one side of the outer wall of the connecting plate 3. The rotating door 4 has a heat dissipation hole 18 inside. The heat dissipation hole 18 is used to facilitate heat dissipation of the device and provides a channel for the heat generated by the operation of the equipment inside the substation to be discharged.

[0026] Working principle: When assembling the substation roof plate 1, the second locking block 19 extends partially out of the sliding frame 9 under the action of the first spring 8. The sliding frame 9 is aligned with the inner wall of the connecting plate 3 and inserted into the slot 11. During the insertion process, the inner wall of the connecting plate 3 will squeeze the second locking block 19, causing it to slide along the sliding groove 10 into the sliding frame 9, compressing the first spring 8. When the sliding frame 9 is fully inserted into the slot 11, the second locking block 19 pops out under the elastic force of the first spring 8 and locks into the corresponding position in the slot 11, achieving a tight connection between the roof plate 1 and the connecting plate 3. At the same time, the positioning post 21 under the roof plate 1 slides into the positioning hole 20 on the mounting plate 2, further ensuring the accuracy of the installation position of the roof plate 1. When installing the partition plate 6, the first locking block 12 contacts the connecting plate 3 under the push of the third spring 15 until the first locking block 12 is locked into the interior of the connecting plate 3, achieving a locking limit and preventing the first locking block 12 from moving further, thereby fixing the partition plate 6 to the connecting plate 3. The roof plate 1 is then disassembled. When manually pressing the sliding column 7, the sliding column 7 drives the second locking block 19 to overcome the elastic force of the first spring 8 and move it into the sliding frame 9, so that the second locking block 19 disengages from the locking slot 11. Then the top plate 1 can be lifted upward to separate it from the connecting plate 3. When disassembling the partition 6, press the button 13. The button 13 compresses the second spring 14 and presses and moves the first locking block 12 until it is disengaged from the connecting plate 3. Then the partition 6 can be pulled out from the connecting plate 3. Finally, the top plate 1 and the support plate 16 of the transformer box are both designed with beveled edges, so that when rainwater comes into contact with the support plate 16, it can flow away along the beveled edge and will not accumulate at the bottom of the substation. This avoids the risk of corrosion and leakage caused by water accumulation and protects the substation from rainwater damage from the bottom. At the same time, the support foot 17 raises the entire substation device, keeping the bottom of the substation a certain distance from the ground, further preventing water from the ground from soaking the bottom of the substation and reducing the possibility of rainwater seeping in from the bottom.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
