Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated substations, specifically a prefabricated substation enclosure assembled with rivets. Background Technology

[0002] Prefabricated substations, also known as box-type substations, are integrated power equipment widely used in urban power grid upgrades, industrial enterprises, and residential communities, providing crucial support for power distribution and conversion. Their enclosures not only protect the internal electrical equipment from external environmental corrosion but also require excellent mechanical strength to withstand various external impacts during transportation, installation, and use.

[0003] Traditional prefabricated substation enclosures are primarily manufactured and assembled using welding or bolting. While welding ensures a strong connection, it requires a high level of skill from the workers, and the high temperatures generated during welding can cause deformation of the enclosure material, affecting the overall appearance and dimensional accuracy. Furthermore, welded enclosures are difficult to repair; once problems occur, significant time and effort are often required for cutting, repairing, and re-welding.

[0004] While bolted connections mitigate the problems of welding deformation to some extent, they require numerous bolt holes in the casing, which weakens its structural strength and increases the complexity of the assembly process. Furthermore, bolts are prone to loosening over long-term use due to vibration and environmental factors, leading to a decline in the casing's sealing performance and affecting the normal operation of internal equipment. Utility Model Content

[0005] To address the problem that bolts are used as connectors in prefabricated substations, which leads to cumbersome installation procedures and weakened structural strength during use, this utility model provides a prefabricated substation enclosure assembled with rivets.

[0006] This utility model is achieved through the following technical solution:

[0007] A box-type substation enclosure assembled with rivets includes a base, a substation shell, and a top cover connected sequentially from bottom to top. The top cover and the base are connected at the corners of the top and bottom of the substation shell by a first connecting plate, respectively.

[0008] The first connecting plate includes a first extension plate and a first fixing plate; the first extension plate is connected to the bottom surface of the top cover or the top surface of the base by rivets; one end of the first fixing plate is connected to the first extension plate, and one end of the first fixing plate is located between the first extension plate and the base or the top cover; the other end of the first fixing plate is connected to the substation housing.

[0009] By replacing traditional welding or bolts with riveting, the assembly process is simplified, eliminating the need for complex equipment or highly skilled workers and significantly shortening the installation time. The design of the first connecting plate tightly connects the top cover, base and the corner of the shell, distributing the force and enhancing the overall structural strength. Whether assembled on-site or transported after partial assembly, it can exhibit good structural strength and improve its resistance to external forces.

[0010] The first extension plate effectively increases the contact area and ease of operation when connecting the top cover or base; a portion of the first fixing plate is located between the first extension plate and the top cover or base, forming a clamping structure, which improves the overall strength of the connection structure.

[0011] A further improvement of this utility model is that the aforementioned first fixing plate includes a first vertical plate and a first horizontal plate; there are two first vertical plates, which are connected to form a right-angle structure, and the two first vertical plates are installed at the corner of the inner wall of the substation shell by rivets; there are two first horizontal plates, which are respectively vertically connected to the upper edge of the two first vertical plates. The right-angle structure of the first vertical plates and the horizontal plates forms a three-dimensional support frame, which significantly improves the compressive and bending resistance at the corner; the combination design of the double vertical plates and the double horizontal plates allows the load to be evenly transferred to the shell and the top cover or base, reducing local stress concentration and extending the service life.

[0012] A further improvement of this invention is that the first transverse plate is mounted on the first extension plate by rivets. The riveting of the first transverse plate and the first extension plate facilitates modular pre-assembly production, reduces on-site assembly complexity, and improves production efficiency; the rivet fastening force ensures that there is no loosening between the first transverse plate and the first extension plate, adapts to long-term vibration environments, and maintains structural stability.

[0013] A further improvement of this utility model is that the first extension plate is provided with a right-angled clearance notch, and the first fixing plate is located within the clearance notch. The clearance notch defines the installation position of the first fixing plate, avoids assembly misalignment, and improves assembly accuracy and consistency; the notch design saves materials while maintaining the strength of the connecting plates, reducing manufacturing costs.

[0014] A further improvement of this invention is that the top surface of the first extension plate is provided with a clearance groove that mates with the first transverse plate. The clearance groove provides guidance for the installation of the first transverse plate on the first extension plate.

[0015] A further improvement of this invention is that the thickness of the first extension plate is greater than the thickness of the first transverse plate, and the depth of the clearance groove is equal to the height of the first transverse plate. The thickened design of the first extension plate provides higher load-bearing capacity, while the depth of the clearance groove matches the height of the first transverse plate, ensuring complete contact between the connecting surfaces and avoiding localized stress concentration.

[0016] A further improvement of this utility model is that the internal space of the substation shell is divided into a high-voltage chamber, a transformer chamber, and a low-voltage chamber by a high-voltage partition and a low-voltage partition; the high-voltage chamber and the low-voltage chamber are respectively located on both sides of the transformer chamber;

[0017] The top of the high-voltage baffle is connected to the substation housing and the top cover via a second connecting plate, and the bottom of the high-voltage baffle is connected to the substation housing and the base via a second connecting plate.

[0018] The top of the low-voltage baffle is connected to the substation housing and the top cover via a second connecting plate, and the bottom of the low-voltage baffle is connected to the substation housing and the base via a second connecting plate.

[0019] The high-voltage and low-voltage baffles are fixed by riveting a second connecting plate to achieve safe isolation of electrical equipment and reduce the risk of electromagnetic interference. Moreover, the second connecting plate can connect the baffle to the top cover or base, increasing the installation structure of the baffle inside the substation shell.

[0020] A further improvement of this utility model is that the aforementioned second connecting plate includes a second extension plate, a second vertical plate a, and a second vertical plate b; the second extension plate is connected to the top cover or base by rivets; the upper edge of the second vertical plate a is vertically connected to the second extension plate; the second vertical plate b is vertically connected to the second vertical plate a, and extends away from the second extension plate. The second vertical plate a and the second vertical plate b cooperate to complete the connection between the partition and the inner wall of the substation housing. The connection between the second vertical plate a and the second extension plate helps to increase the structural strength of the connection between the partition and the top cover or base, ultimately improving the stability of the partition installation within the substation housing.

[0021] As can be seen from the above technical solutions, the beneficial effects of this utility model are: replacing traditional welding or bolts with rivet connections simplifies the assembly process, eliminates the need for complex equipment or highly skilled workers, and significantly shortens the installation time; the design of the first connecting plate tightly connects the top cover, base, and corner of the shell, distributing the force and enhancing the overall structural strength. Whether assembled on-site or transported after partial assembly, it can exhibit good structural strength and improve its resistance to external forces.

[0022] The first extension plate effectively increases the contact area and ease of operation when connecting the top cover or base; a portion of the first fixing plate is located between the first extension plate and the top cover or base, forming a clamping structure, which improves the overall strength of the connection structure.

[0038] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0039] like Figures 1-10 As shown, this utility model discloses a box-type substation enclosure assembled with rivets, including a base 40, a substation shell 10 and a top cover 50 connected sequentially from bottom to top. The top cover 50 and the base 40 are connected at the corners of the top and bottom ends of the substation shell 10 by a first connecting plate 20.

[0040] The internal space of the substation housing 10 is divided into a high-voltage chamber 12, a transformer chamber 11, and a low-voltage chamber 13 by a high-voltage partition 14 and a low-voltage partition 15; the high-voltage chamber 12 and the low-voltage chamber 13 are respectively located on both sides of the transformer chamber 11.

[0041] The top of the high-voltage baffle 14 is connected to the substation housing 10 and the top cover 50 via the second connecting plate 30, and the bottom of the high-voltage baffle 14 is connected to the substation housing 10 and the base 40 via the second connecting plate 30.

[0042] The top of the low-voltage partition 15 is connected to the substation housing 10 and the top cover 50 via the second connecting plate 30, and the bottom of the low-voltage partition 15 is connected to the substation housing 10 and the base 40 via the second connecting plate 30.

[0043] The high-voltage baffle 14 and the low-voltage baffle 15 are fixed by riveting the second connecting plate 30 to achieve safe isolation of electrical equipment and reduce the risk of electromagnetic interference; moreover, the second connecting plate 30 can connect the baffle to the top cover 50 or the base 40, which increases the installation structure of the baffle in the substation shell 10.

[0044] The second connecting plate 30 includes a second extension plate 31, a second vertical plate a32, and a second vertical plate b33. The second extension plate 31 is connected to the top cover 50 or the base 40 via rivets 70. The upper edge of the second vertical plate a32 is vertically connected to the second extension plate 31. The second vertical plate b33 is vertically connected to the second vertical plate a32 and extends away from the second extension plate 31. The second vertical plate a32 and the second vertical plate b33 cooperate to complete the connection between the partition and the inner wall of the substation housing 10. The connection between the second vertical plate a32 and the second extension plate 31 helps to increase the structural strength of the connection between the partition and the top cover 50 or the base 40, ultimately improving the stability of the partition installation within the substation housing 10.

[0045] The substation shell 10 comprises multiple sets of door panels 16 and multiple wall panels 17. The high-voltage chamber 12, transformer chamber 11, and low-voltage chamber 13 are enclosed by a high-voltage partition 14, a low-voltage partition 15, and two sets of opposing door panels 16. The high-voltage chamber 12 is enclosed by a set of door panels 16, a high-voltage partition 14, and two opposing wall panels 17. The low-voltage chamber 13 is enclosed by a set of door panels 16, a low-voltage partition 15, and two opposing wall panels 17.

[0046] The door panel 16 is connected to the wall panel 17 via a third connecting plate 60; the third connecting plate 60 is a hinge plate, and the two hinged parts of the hinge plate are connected to the door panel 16 and the wall panel 17 via rivets 70 respectively.

[0047] The upper part of the high-pressure baffle 14 is connected to the wall panel 17 and the top cover 50 via the second connecting plate 30, and the lower part of the high-pressure baffle 14 is connected to the wall panel 17 and the base 40 via the second connecting plate 30. The upper part of the low-pressure baffle 15 is connected to the wall panel 17 and the top cover 50 via the second connecting plate 30, and the lower part of the low-pressure baffle 15 is connected to the wall panel 17 and the base 40 via the second connecting plate 30.

[0048] The second connecting plate 30 is initially a complete rectangular plate. A slit is cut into the rectangular plate, located in the middle of its wide side, with its length parallel to the long side and half the length of the long side. The rectangular plate is then bent 90° along the slit's length, resulting in a second extension plate 31 on one side. The other part of the plate is folded 90° away from the second extension plate 31. The portion connecting to the second extension plate 31 is the second vertical plate a32, and the remaining portion connecting only to the second vertical plate a32 is the second vertical plate b33. During on-site use or manufacturing, it is necessary to distinguish in advance whether the second vertical plate a32 is folded upwards or downwards relative to the second extension plate 31, thus accommodating the adaptability of the second connecting plate 30 in different positions on the partition.

[0049] The first connecting plate 20 includes a first extension plate 21 and a first fixing plate 22; the first extension plate 21 is connected to the bottom surface of the top cover 50 or the top surface of the base 40 by rivets 70; one end of the first fixing plate 22 is connected to the first extension plate 21, and one end of the first fixing plate 22 is located between the first extension plate 21 and the base 40 or the top cover 50; the other end of the first fixing plate 22 is connected to the substation housing 10.

[0050] The assembly process is simplified by using rivets 70 instead of traditional welding or bolts, eliminating the need for complex equipment or highly skilled workers and significantly shortening the installation time. The design of the first connecting plate 20 tightly connects the top cover 50, the base 40 and the corner of the shell, distributing the force and enhancing the overall structural strength. Whether assembled on-site or transported after partial assembly, it can exhibit good structural strength and improve its resistance to external forces.

[0051] The first extension plate 21 effectively increases the contact area and ease of operation for connecting the top cover 50 or the base 40; a portion of the first fixing plate 22 is located between the first extension plate 21 and the top cover 50 or the base 40, forming a clamping structure, which improves the overall strength of the connection structure.

[0052] The first fixing plate 22 includes a first vertical plate 221 and a first horizontal plate 222. Two first vertical plates 221 are provided, connected at a right angle, and installed at the corner of the inner wall of the substation housing 10 by rivets 70. Two first horizontal plates 222 are provided, each vertically connected to the upper edge of one of the two first vertical plates 221. The right-angled first vertical plates 221 and the horizontal plates form a three-dimensional support frame, significantly improving the compressive and bending resistance at the corner. The combination of the double vertical and double horizontal plates ensures that the load is evenly distributed between the housing and the top cover 50 or the base 40, reducing local stress concentration and extending service life.

[0053] The first transverse plate 222 is mounted on the first extension plate 21 by rivets 70. The riveting of the first transverse plate 222 and the first extension plate 21 helps to achieve modular pre-assembly production, reduces on-site assembly complexity, and improves production efficiency; the fastening force of the rivets 70 ensures that there is no loosening between the first transverse plate 222 and the first extension plate 21, adapts to long-term vibration environment, and maintains structural stability.

[0054] The first extension plate 21 has a right-angled clearance notch 211, and the first fixing plate 22 is located within the clearance notch 211. The clearance notch 211 defines the installation position of the first fixing plate 22, avoids assembly misalignment, and improves assembly accuracy and consistency; the notch design saves materials while maintaining the strength of the connecting plates and reducing manufacturing costs.

[0055] The top surface of the first extension plate 21 is provided with a clearance groove 212 that mates with the first transverse plate 222. The clearance groove 212 provides guidance for the installation of the first transverse plate 222 on the first extension plate 21.

[0056] The thickness of the first extension plate 21 is greater than the thickness of the first transverse plate 222, and the depth of the clearance groove 212 is equal to the height of the first transverse plate 222. The thickened design of the first extension plate 21 provides higher load-bearing capacity, while the depth of the clearance groove 212 matches the height of the first transverse plate 222, ensuring complete contact of the connecting surfaces and avoiding local stress concentration.

[0057] All components through which rivets 70 pass are provided with rivet holes 80.

[0058] The present invention describes a box-type substation enclosure assembled with rivets. The rivet connection replaces the traditional welding or bolts, simplifying the assembly process, eliminating the need for complex equipment or highly skilled workers, and significantly shortening the installation time. The design of the first connecting plate tightly connects the top cover, base and corner of the shell, distributing the force and enhancing the overall structural strength. Whether assembled on-site or transported after partial assembly, it can exhibit good structural strength and improve its resistance to external forces.

[0059] The first extension plate effectively increases the contact area and ease of operation when connecting the top cover or base; a portion of the first fixing plate is located between the first extension plate and the top cover or base, forming a clamping structure, which improves the overall strength of the connection structure.
