Description

Technical Field

[0001] The present invention relates to the technical field of box-type substations, and in particular to a convenient modular assembled box-type substation. Background Art

[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a factory-prefabricated indoor or outdoor compact power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment according to a specific wiring scheme.

[0003] The existing patent application number CN119093200A is an authorized patent "A modular box-type substation shell", which "comprises a box frame, wherein the box frame has a first side panel installed on two sides, and the second side panel is installed on the other two sides of the box frame, and the box frame cooperates with the first side panel and the second side panel to form a substation built-in cavity, and the top of the box frame is fixedly installed with a top frame, and the top of the top frame is plugged in and pasted with a heat insulation shield, and the bottom of the box frame is paved with a bottom plate, and several bottoms block the bottom opening of the box frame; the box frame includes a bottom bracket, and the upper four corners of the bottom bracket are plugged in and installed with support columns, and the first side panel or the second side panel is plugged in between two adjacent support columns; the upper part of the bottom bracket is also provided with a top bracket, and the lower four corners of the top bracket are plugged in with the upper four support columns; the bottom bracket and the top bracket have the same structure, and the bottom bracket includes a first telescopic plate, and the first telescopic plate is provided with two, and the two A second telescopic plate is also plugged and installed between the two ends of the first telescopic plate through a connecting piece. "Thereby achieving "the box frame can be adjusted according to actual needs. During transportation, the first telescopic plate and the second telescopic plate are in a retracted state. During installation, the first telescopic plate and the second telescopic plate can be extended outward to widen and adjust to adapt to substations of different sizes and shapes. At the same time, due to the adoption of a plug-in structure, the various parts of the box frame can be easily disassembled and assembled, further enhancing its modular characteristics" and "when the square cone rotates with the rotating rod, the driving rod also rotates, and the convex part of the driving rod squeezes the rod body. When squeezed, the rod body can overcome the tension of the second spring and move outward to insert into the inner wall of the auxiliary support plate, thereby achieving bolt-free fixation between the connecting piece and the auxiliary support plate. Similarly, by squeezing the rod body, the other three elastic clamping rods are driven to insert into the main support plate, completing the bolt-free fixation between the main support plate and the auxiliary support plate. The bolt-free installation achieves quick connection through structures such as the driving rod and the elastic clamping rod."

[0004] However, when the above-mentioned box-type substation shell is used, the telescopic structure needs to adjust the length of different telescopic rods separately during use. After confirming the overall frame length of the box-type substation, separate adjustments are made. In addition, although a boltless installation design is adopted, under long-term outdoor complex environments (such as vibration, temperature changes, etc.), the plug-in parts will become loose due to frequent stress or material fatigue, affecting the stability of the overall structure. For example, when encountering external forces such as strong winds or earthquakes, the connections between the modules will become loose, causing the box to deform or even fall apart.

[0005] In addition, when the telescopic plate structure of the box frame bears a large weight (such as transformers and other equipment), local deformation or insufficient support strength will occur. Local deformation will cause the installation foundation of the equipment in the box (such as transformers, switch cabinets, etc.) to be uneven, causing the equipment to tilt or shift.

[0006] To this end, we propose a convenient modular assembled box-type substation to solve the above problems. Summary of the Invention

[0022] Beneficial effects

[0023] Compared with the prior art, the present invention provides a convenient modular assembled box-type substation with the following beneficial effects:

[0024] By setting up the directional support, three sets of mutually parallel horizontal positioning rods and horizontal connecting rods as well as the cross-shaped frame and the long connecting rod can be connected. Thus, while the frame constituting the box-type substation can be changed according to different sizes of box-type substations, the length of the adjacent frames can be adjusted at the same time. The directional support forms a stable support through the truss structure, integrating the scattered horizontal connecting rods and long connections into a whole, thereby enhancing the bending and torsion resistance. In addition, when the length of the adjacent frames is adjusted, the directional support automatically compensates for the displacement difference through rigid connection, ensuring that the overall structure is evenly stressed and avoiding local stress concentration.

[0025] The support of the support rods can balance the stress in the centers of the two sets of rectangular frames. The support rods connect the centers of the two sets of rectangular frames, integrating the scattered frames into a whole and balancing the stress differences caused by uneven loads or external forces (such as wind loads and vibrations);

[0026] In addition, through the setting of elastic support rods, the elastic support rods act as elastic supports to balance the external forces exerted on the pre-assembled frame of the integral box-type substation during specific use. The elastic support rods can absorb the impact generated during operation (such as wind load shaking) and reduce the transmission of these external forces to the frame and internal equipment. Under the action of wind load or earthquake, the support rods offset the lateral force through elastic deformation to maintain the verticality of the frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Further embodiments

[0054] See also Figures 3 to 5 and Figures 8 to 10 , the convenient modular assembled box-type substation further includes a support assembly arranged between the cross-shaped frames 21;

[0055] The support assembly includes a bidirectional threaded rod 41 rotatably connected to the outer wall of the support rod 38, the outer surfaces of both ends of the bidirectional threaded rod 41 are threadedly connected to the driven ring 42, the outer surfaces of the driven ring 42 are symmetrically fixedly connected to the positioning shaft 43 with the central axis of the driven ring 42 as a reference, the positioning shaft 43 is rotatably connected to the end away from the driven ring 42 with an elastic telescopic rod 44, the inner surfaces of the upper and lower ends of the support frame rod 31 are fixedly connected to the fixing parts 45 by bolts, and the outer surface of the fixing parts 45 away from the support frame rod 31 is fixedly connected to the support spring 46.

[0056] Among them, the threads set on the outer surfaces of both ends of the bidirectional threaded rod 41 have opposite spiral directions, the elastic telescopic rod 44 is rotatably connected to the inner surface of the support frame rod 31 at one end away from the positioning shaft 43, and the support spring 46 is fixedly connected to the outer surface of the elastic telescopic rod 44 at one end away from the fixing part 45.

[0057] The two fixing members 45 in the same vertical direction are arranged between the two elastic telescopic rods 44 .

[0058] In the initial state, the driven ring 42 is located at the center of the bidirectional threaded rod 41 , that is, the elastic telescopic rod 44 is in an inclined state.

[0059] The working process and principle of the above embodiment are as follows:

[0060] Box-type substation frame assembly:

[0061] After the staff transports the box-type substation assembly frame to the predetermined location through the conveying equipment, they place one of the cross-shaped frames 21 on the ground, and then place the two long connecting rods 22 and the two horizontal positioning rods 26 in accordance with the Figure 3 Insert the vertical connecting rod 24 into the four end points of the cross frame 21 in the direction shown, and slide the vertical connecting rod 24 into the vertical positioning rod 23, and insert the horizontal connecting rod 27 into the two ends of the horizontal positioning rod 26;

[0062] Then, the staff adjusted the length of the long connecting rod 22 inside the cross-shaped frame 21, the distance between the horizontal connecting rod 27 and the horizontal positioning rod 26, and the distance between the vertical connecting rod 24 and the vertical positioning rod 23 according to the sizes of the long side panels 11 and the short side panels 12. At the same time, a positioning block 29 was placed at the intersection of the horizontal connecting rod 27 and the vertical connecting rod 24, and the positioning block 29 was fixedly connected to the horizontal connecting rod 27 and the vertical connecting rod 24 by bolts. Then, the staff placed the directional support 28 between the long connecting rod 22 and the horizontal connecting rod 27, and fixed the directional support 28 and the horizontal connecting rod 27, as well as the long connecting rod 22 and the horizontal connecting rod 27, by bolts.

[0063] It should be noted that the distance between the end points of the two long connecting rods 22 and the distance between the end points of the two horizontal connecting rods 27 arranged in the same horizontal direction is equal to the length of the long side plate 11, and the distance between the end points of the two vertical connecting rods 24 at both ends of the same vertical positioning rod 23 is equal to the length of the short side plate 12;

[0064] At this time, the cross-shaped frame 21, the long connecting rod 22, the vertical positioning rod 23, the vertical connecting rod 24, the short connecting rod 25, the horizontal positioning rod 26, the horizontal connecting rod 27, the vertical positioning rod and the positioning block 29 together constitute a rectangular frame structure. Since the cross-shaped frame 21, the long connecting rod 22, the vertical positioning rod 23, the vertical connecting rod 24, the short connecting rod 25, the horizontal positioning rod 26, the horizontal connecting rod 27, the vertical positioning rod and the positioning block 29 are all set in two groups, the staff needs to continue to assemble another group of rectangular frames according to the above steps;

[0065] By setting the directional support 28, the three sets of parallel horizontal positioning rods 26 and horizontal connecting rods 27 as well as the cross frame 21 and the long connecting rod 22 can be connected, so that the frame constituting the box-type substation can be changed according to different sizes of box-type substations, and the length of the adjacent frames can be adjusted at the same time. The directional support 28 forms a stable support through the truss structure, integrating the scattered horizontal connecting rods 27 and the long connection into a whole, thereby enhancing the bending and torsion resistance. In addition, when the length of the adjacent frames is adjusted, the directional support 28 automatically compensates for the displacement difference through the rigid connection, ensuring that the overall structure is evenly stressed and avoiding local stress concentration.

[0066] After the two sets of rectangular frames are assembled, the staff will lift one set of rectangular frames using an external lifting device, and then place the support frame rod 31 between the two sets of rectangular frames. At this time, the support frame rod 31 is installed by plugging it into the positioning slots 32 opened at both ends of the support frame rod 31, the positioning blocks 33, and the vertical plug-in blocks 34. The four support frame rods 31 are installed in sequence according to the above steps.

[0067] It should be noted that, since the shape and size of the positioning groove 32 are adapted to the positioning block 33 and the vertical plug-in block 34, the frame-type housing of the box-type substation can be quickly assembled through the positioning groove 32, the positioning block 33 and the vertical plug-in block 34;

[0068] In addition, since threaded holes 36 are provided on both the support frame rod 31 and the vertical plug-in card block 34, and the threaded holes 36 on the vertical plug-in card block 34 are respectively located on both sides of the vertical plug-in card block 34, and the threaded holes 36 on the vertical plug-in card block 34 all pass through the vertical plug-in card block 34 and communicate with the vertical plug-in card slot 35, the staff can fix the vertical plug-in card block 34 to the support frame rod 31 with bolts;

[0069] It should be noted that, since the vertical plug-in card slot 35 divides the vertical plug-in card block 34 into two parts, when the vertical plug-in card block 34 is fixed to the support frame rod 31, the two bolts located at both ends of the vertical plug-in card slot 35 will interfere with each other in the vertical plug-in card slot 35, thereby fixing the vertical plug-in card block 34 to the support frame rod 31;

[0070] After installation, the staff inserts the support rods 38 into the two limit blocks 37 to fix the positions of the two cross-shaped frames 21 through the support rods 38 and the limit blocks 37. It should be noted that rubber damping rings are provided inside the limit blocks 37 and at both ends of the support rods 38 to increase the friction between the limit blocks 37 and the support rods 38, thereby fixing the center of the rectangular frame and balancing the stress of the rectangular frame.

[0071] Then the staff moves one end of the elastic telescopic rod 44 away from the positioning shaft 43 to contact the inner wall of the support frame rod 31, and then fixes the fixing piece 45 to the inner wall of the support frame rod 31 with a bolt. The staff rotates the bidirectional threaded rod 41 located on the outer surface of the support rod 38. Since the screw threads at both ends of the bidirectional threaded rod 41 are arranged in opposite directions, the rotation of the bidirectional threaded rod 41 will cause the driven rings 42 threadedly connected to the two ends of the bidirectional threaded rod 41 to move toward the two cross-shaped frames 21, that is, the two driven rings 42 will move away from each other.

[0072] At this time, the elastic telescopic rod 44 provided on the outer surface of the driven ring 42 via the positioning shaft 43 will move accordingly, and because the other end of the elastic telescopic rod 44 abuts against the L-shaped inner wall of the support frame rod 31, and the fixing member 45 is fixed to the inner wall of the support frame rod 31 by bolts, as the driven ring 42 and the elastic telescopic rod 44 move, the elastic telescopic rod 44 will gradually support the space between the support rod 38 and the support frame rod 31;

[0073] It should be noted that, in the initial state, the driven ring 42 is located at the center of the bidirectional threaded rod 41, that is, the elastic telescopic rod 44 is in an inclined state at this time. Therefore, with the movement of the driven ring 42, the elastic telescopic rod 44, which was originally in an inclined state, will gradually become a horizontal state. At this time, the elastic telescopic rod 44 itself will be squeezed by the support rod 38 and the support frame rod 31, and will shrink. At the same time, the elastic telescopic rod 44 will apply synchronous pressure to the support frame rod 31 in the reverse direction until the elastic telescopic rod 44 is completely in a horizontal state. In this state, the support spring 46 provided between the elastic telescopic rod 44 and the fixing member 45 will also be deformed accordingly to support the position of the elastic telescopic rod 44.

[0074] Then the staff placed the long side panels 11 and the short side panels on the outside of the support frame rod 31 respectively, and fixed the long side panels 11 and the short side panels 12 to the outside of the support frame rod 31 with bolts, and connected the long side panels 11 and the short side panels 12 with hinges 13. Then, the roof 14 was lifted to the upper surface of the positioning block 29 above by the external lifting device, and the roof 14 was fixed to the positioning block 29 with bolts. The assembly of the box-type substation was completed;

[0075] The support of the support rod 38 can balance the stress in the center of the two sets of rectangular frames. The support rod 38 connects the centers of the two sets of rectangular frames, integrating the scattered frames into a whole, and balancing the stress differences caused by uneven loads or external forces (such as wind loads and vibrations);

[0076] In addition, through the provision of the elastic support rod 38, the elastic support rod 38 acts as an elastic support to balance the external forces exerted on the pre-assembled frame of the integral box-type substation during specific use. The elastic support rod 38 can absorb the impact generated during operation (such as wind load shaking), and reduce the transmission of these external forces to the frame and internal equipment. Under the action of wind load or earthquake, the support rod 38 offsets the lateral force through elastic deformation to maintain the verticality of the frame.
