Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to a modular prefabricated transformer structure that is easy to move. Background Technology

[0002] With the large-scale development of the new energy industry, the accelerated construction of new infrastructure, and the normalization of emergency power supply needs, prefabricated substations, as core equipment for power conversion and transmission, have been widely used in diverse scenarios such as photovoltaic power generation, wind power generation, energy storage power stations, urban distribution network upgrades, temporary power supply for construction sites, and emergency support for natural disasters. Compared with traditional substations, prefabricated substations integrate high-voltage switches, transformers, low-voltage distribution devices, and other equipment into a sealed enclosure, offering advantages such as small footprint, convenient installation, and reliable operation. This significantly shortens the on-site construction cycle, reduces site planning costs, and makes them a key piece of equipment in modern power systems. However, in actual mobile applications, the mobility reliability of existing mobile transformer substation structures still has significant hidden dangers. For example, a Chinese patent with application number "201811581857.1" shows that the problem caused by the unreasonable bottom roller design is particularly significant: when the transformer substation moves on uneven ground, the bottom rollers collide with obstacles such as gravel and protruding roadbeds, which can easily disrupt the original force balance of the cabinet, causing the center of gravity of the transformer substation to shift and become unbalanced, which may lead to the risk of the cabinet tilting or even overturning. This may not only damage the precision electrical components inside the transformer substation, but also threaten the personal safety of on-site workers, seriously restricting the safe application of mobile transformer substations in complex site scenarios. In view of this, we propose a modular transformer substation structure that is easy to move in order to solve the above-mentioned technical problems. Summary of the Invention

[0003] The present invention provides the following technical solution: a modular box-type substation structure that is easy to move, including a mobile module and a box-type substation module fixed to the top of the mobile module, wherein the mobile module and the box-type substation module form a movable modular box-type substation structure; The moving module includes a support component, a moving component, a side support component, a catapult component, and an anti-slip component; The support includes a base plate, a top plate located on top of the base plate, and several pillars fixedly installed between the base plate and the top plate. The pillars support the space between the base plate and the top plate, and the transformer substation module is fixedly installed on the top of the top plate. The movable component includes linear bearings fixedly installed at the four corners of the base plate, and guide shafts vertically slidably installed inside the linear bearings. A support plate is fixedly installed at the bottom of the guide shaft, and rollers are fixedly installed at the bottom of the support plate. The rollers are used for moving this modular transformer substation structure. The side support includes a slide plate that is slidably disposed on the bottom of the bottom plate along the length of the bottom plate, and a side support square tube that is fixedly installed on the bottom of the slide plate by a connecting plate; The ejector is positioned between the bottom plate and the top plate, and extends to the bottom of the bottom plate.

[0004] As a preferred embodiment of the present invention, four linear bearings are distributed in a "U" shape at the four corners of the base plate, the support plate is fixedly installed at the bottom of the four guide shafts, and springs are sleeved around the guide shafts. The springs are fixedly installed between the bottom of the base plate and the top of the support plate.

[0005] As a preferred embodiment of the present invention, a locking groove is provided at the bottom of the side support square tube along its length direction. A Z-shaped sheet metal bracket is fixedly installed between the front and rear support plates distributed on the left and right sides of the central axis of the base plate. There are two Z-shaped sheet metal brackets. A locking bolt is installed vertically in the middle of each of the two Z-shaped sheet metal brackets. The two locking bolts are respectively inserted into the two ends inside the locking groove.

[0006] As a preferred embodiment of the present invention, the ejector includes two settling plates disposed between the bottom plate and the top plate. The two settling plates are symmetrical about the central axis of the bottom plate, and the two settling plates are respectively fixedly installed on the top of the guide shafts distributed on both sides of the central axis of the bottom plate. Two wedges are provided opposite to each other at the bottom of the two settling plates, and the two wedges are provided at an angle to each other. The bottom of the two wedges is higher than the top of the slide plate.

[0007] As a preferred embodiment of the present invention, two rectangular grooves for accommodating the movement of the wedges are provided through the top of the base plate along its length, and the two rectangular grooves are symmetrical about the central axis of the base plate. The ejector also includes two power-storing grooves formed on its top along the length of the side support square tube. The positions of the two power-storing grooves correspond one-to-one with the positions of the two wedges. Power-storing sliders are slidably installed inside the two power-storing grooves. The power-storing sliders are located at the bottom of the corresponding angle. A U-shaped spring is also fixedly installed inside the power-storing groove. The U-shaped spring is fixed between the surface of the power-storing slider and one inner wall of the power-storing groove.

[0008] As a preferred embodiment of the present invention, the anti-slip component includes square holes that penetrate through the four corners of the top of the skateboard, and U-shaped blocks that are slidably installed inside the front and rear square holes. The U-shaped blocks are located around the side support square tubes. A screw is fixedly installed on the outer surface of the U-shaped blocks. A screw is fixedly installed on the side of the skateboard near the screw. A tension spring is fixedly installed between the screw and the screw.

[0009] As a preferred embodiment of the present invention, both ends of the U-shaped stop are rotatably provided with rolling balls. Initially, the top of the rolling balls abuts against the bottom of the base plate so that the tension spring is in a stretched and stored state. Solid lubricating grease is coated between the inner wall of the square hole and the outer surface of the U-shaped stop.

[0010] As a preferred embodiment of the present invention, two symmetrical foot pedals are fixedly provided on the U-shaped stop, the two foot pedals are located at the ends of the slide plate, and the gap between the two foot pedals is greater than the width of the wedge block. The top of each foot pedal is provided with a number of anti-slip holes at equal intervals in both directions.

[0011] As a preferred embodiment of the present invention, both ends of the side support square tube are fixedly provided with abutment blocks, and the length of the abutment blocks is less than the width between the two opposing inner walls of the U-shaped sheet metal bracket.

[0012] As a preferred embodiment of the present invention, the top height of the locking bolt is lower than the bottom height of the U-shaped spring.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. When two rollers on one side are lifted off the ground by the tilted transformer module, the compressed spring's rebound force is released, pushing the support plate and rollers to move along the sliding trajectory of the guide shaft and linear bearing. During this process, the support plate also moves the Z-shaped sheet metal bracket and locking bolt together, eventually causing the locking bolt to exit from the bottom of the locking groove, releasing the sliding lock on the side support square tube. The tilted side support square tube, connecting plate, and sliding plate slide along the bottom of the base plate towards the side of the transformer module that is tilted, and drive the abutment block to extend from the bottom of the transformer module together, providing lateral support towards the side of the transformer module that is tilted, so as to prevent the transformer module from tipping over.

[0014] 2. When the transformer substation module tilts, the spring force at the upward-tilting end releases the tilted-up end, causing the guide shaft to slide along the linear bearing. During this process, the guide shaft also moves the settling plate located between the bottom and top plates. The settling plate, connected by wedges, moves the angled section, bringing it into contact with the top of the energy storage slider. A wedge force is applied to the angled section along the sliding direction of the energy storage slider and the energy storage groove. The U-shaped spring is compressed and stores elastic force. As the locking bolt exits from the bottom of the locking groove, the side support square tube is released. The compressed, stored elastic force of the U-shaped spring is released instantaneously, propelling the side support square tube to slide rapidly. This allows the side support square tube to quickly extend towards the side of the tilted transformer substation module, preventing insufficient lateral support and thus avoiding the transformer substation module from tipping over due to inadequate lateral support, thereby reducing the risk of accidents.

[0015] 3. As the sliding plate extends along the bottom of the base plate towards the side where the transformer module tilts, the sliding plate also moves the U-shaped stop, screw one, screw two, tension spring, and ball bearings together through the square hole. The rotational characteristics of the ball bearings reduce the damping of the U-shaped stop sliding along the bottom of the base plate, thereby reducing the sliding resistance of the side support square tube, sliding plate, and other components. This ensures that the speed at which the side support square tube is ejected towards the side where the transformer module tilts is not affected. When the side support square tube is fully extended, the U-shaped stop slides to one end of the base plate with the sliding plate. The tension spring, which is in a stretched and stored state, releases its rebound force, pulling the U-shaped stop upward along the inside of the square hole. This stops the U-shaped stop at the end of the base plate, ensuring that the extended side support square tube does not slide in the opposite direction, thus providing a stable lateral support effect.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-12 The technical solution provided by the present invention specifically includes the following embodiments: A modular prefabricated substation structure that is easy to move includes a mobile module 100 and a prefabricated substation module 200 fixed to the top of the mobile module 100. The mobile module 100 and the prefabricated substation module 200 form a movable modular prefabricated substation structure. The mobile module 100 includes a support member 300, a moving member 400, a side support member 500, a catapult member 600, and an anti-slip member 700.

[0020] For further details, please refer to [link / reference]. Figure 4 , Figure 6 , Figure 7 As shown: The support member 300 includes a base plate 301, a top plate 302 located on top of the base plate 301, and a plurality of columns 303 fixedly disposed between the base plate 301 and the top plate 302. The columns 303 support the base plate 301 and the top plate 302 to form a space. The transformer substation module 200 is fixedly disposed on the top of the top plate 302 and supported between the base plate 301 and the top plate 302 by the columns 303, so that a certain height space is maintained between the base plate 301 and the top plate 302. Furthermore, multiple columns 303 are provided to make the spatial structure formed between the base plate 301 and the top plate 302 more stable. The movable component 400 includes linear bearings 401 fixedly installed at the four corners of the base plate 301, and guide shafts 402 vertically slidably installed inside the linear bearings 401. A support plate 403 is fixedly installed at the bottom of the guide shaft 402, and a roller 404 is fixedly installed at the bottom of the support plate 403. The roller 404 is used for moving the modular transformer substation structure. Four linear bearings 401 are distributed in a "U" shape at the four corners of the base plate 301. The support plate 403 is fixedly installed at the bottom of the four guide shafts 402. A spring 405 is sleeved around the guide shaft 402. The spring 405 is fixedly installed between the bottom of the base plate 301 and the top of the support plate 403. During normal use, the modular transformer substation structure relies on four rollers 404 touching the ground to support it, ensuring its stability. When necessary, the four rollers 404 facilitate movement of the modular transformer substation structure. When the rollers 404 are in normal support, they are pressed down by the weight of the transformer substation module 200 and the moving module 100. The linear bearing 401 slides along the outer wall of the guide shaft 402 towards the support plate 403. In the final state, the bottom of the linear bearing 401 contacts the top of the support plate 403, and the spring 405 is compressed to store elastic force, utilizing the support plate 403. The top support of the linear bearing 401 further provides support for the support member 300 and the transformer module 200 as a whole. During the movement, if one of the rollers 404 is tripped by an object, causing the transformer module 200 to tilt, the two rollers 404 on the other side will be lifted away from the ground by the tilted transformer module 200. The spring 405 under compression will be released, pushing the support plate 403 and rollers 404 to move along the sliding trajectory of the guide shaft 402 and the linear bearing 401, causing the side support member 500 to be unlocked.

[0021] For further details, please refer to [link / reference]. Figure 6 , Figure 8 , Figure 9 , Figure 11 As shown: The side support component 500 includes a sliding plate 501 that is slidably disposed at the bottom of the base plate 301 along the length direction of the base plate 301, and a side support square tube 503 that is fixedly installed at the bottom of the sliding plate 501 via a connecting plate 502. The bottom of the side support square tube 503 is provided with a locking groove 505 along its length direction. A Z-shaped sheet metal bracket 506 is fixedly installed between the front and rear support plates 403 distributed on the left and right sides of the central axis of the base plate 301. There are two Z-shaped sheet metal brackets 506. Each of the two Z-shaped sheet metal brackets 506 has a locking bolt 507 vertically threaded in the middle. The two locking bolts 507 are respectively inserted into the two ends inside the locking groove 505. Both ends of the side support square tube 503 are fixedly provided with abutment blocks 504. The length of the abutment block 504 is less than the width between the two opposing inner walls of the Z-shaped sheet metal bracket 506. When the two rollers 404 on one side are lifted off the ground by the tilted transformer module 200, the compressed spring 405 is released, pushing the support plate 403 and rollers 404 to move along the sliding trajectory of the guide shaft 402 and linear bearing 401. During this process, the support plate 403 also drives the U-shaped sheet metal bracket 506 and locking bolt 507 to move together, eventually causing the locking bolt 507 to come out from the bottom of the locking groove 505, releasing the sliding lock on the side support square tube 503. The side support square tube 503, connecting plate 502 and sliding plate 501, which are in a tilted state, slide along the bottom of the base plate 301 toward the side of the tilted transformer module 200, and drive the abutment block 504 to extend from the bottom of the transformer module 200 together, providing lateral support toward the side of the tilted transformer module 200 to prevent the transformer module 200 from tipping over.

[0022] For further details, please refer to [link / reference]. Figure 9 , Figure 10 , Figure 11 As shown: The ejector component 600 includes two settling plates 601 disposed between a base plate 301 and a top plate 302. The two settling plates 601 are symmetrical about the central axis of the base plate 301, and the two settling plates 601 are respectively fixedly installed on the top of guide shafts 402 distributed on both sides of the central axis of the base plate 301. Two wedges 602 are provided opposite each other at the bottom of the two settling plates 601. The top of the base plate 301 has two rectangular grooves that are symmetrical about the central axis of the base plate 301. The two wedges 602 are provided opposite each other. The angle is 603, and the bottom of the two wedges 602 is higher than the top of the slide plate 501. The ejector 600 also includes two power storage grooves 604 opened on the top of the side support square tube 503 along its length direction. The positions of the two power storage grooves 604 correspond one-to-one with the positions of the two wedges 602. Power storage sliders 605 are slidably installed inside the two power storage grooves 604. The power storage sliders 605 are located at the bottom of the angle 603 at the corresponding positions. A U-shaped spring piece 606 is also fixedly installed inside the power storage groove 604. The U-shaped spring piece 606 is fixed between the surface of the power storage slider 605 and the inner wall of one side of the power storage groove 604. When the transformer module 200 tilts, the spring 405 at the upward-tilting end releases its elastic force, causing the guide shaft 402 to slide along the interior of the linear bearing 401. During this sliding process, the guide shaft 402 also drives the settling plate 601 located between the bottom plate 301 and the top plate 302 to move along with the guide shaft 402. The settling plate 601, connected by the wedge block 602, drives the inclined angle 603 to move, causing the inclined angle 603 to contact the top of the energy storage slider 605. This applies a wedge force to the inclined angle 603 along the sliding direction of the energy storage slider 605 and the energy storage groove 604. Simultaneously, because the Z-shaped sheet metal bracket 506 carrying the locking bolt 507 has not yet fully withdrawn from the locking groove 505, the side support square tube 503 cannot slide. Therefore, the inclined angle 603 exerts a force on the energy storage slider... The wedge force of 605 can only cause the energy storage slider 605 to slide along the energy storage groove 604. The U-shaped spring 606 is compressed and stores elastic force. As the Z-shaped sheet metal bracket 506 continues to drive the locking bolt 507 to move, the locking bolt 507 eventually exits from the bottom of the locking groove 505, and the side support square tube 503 is released from its lock. The elastic force of the U-shaped spring 606, which is under compression and storage, is released instantly, pushing the side support square tube 503 to slide quickly. This allows the side support square tube 503 to pop out to the side where the transformer module 200 is tilting in a short time. This avoids the transformer module 200 from being overturned due to insufficient lateral support caused by the side support square tube 503 not extending quickly enough. This reduces the occurrence of safety accidents.

[0023] For further details, please refer to [link / reference]. Figure 12 As shown: The anti-slip component 700 includes square holes 701 that penetrate the four corners of the top of the slide plate 501, and U-shaped blocks 702 that are slidably installed inside the front and rear square holes 701. The U-shaped blocks 702 are located around the side support square tube 503. A screw 703 is fixedly installed on the outer surface of the U-shaped blocks 702. A screw 704 is fixedly installed on the side of the slide plate 501 near the screw 703. A tension spring 705 is fixedly installed between the screw 703 and the screw 704. A ball bearing 706 is rotatably installed at both ends of the U-shaped blocks 702. Initially, the top of the ball bearing 706 abuts against the bottom of the base plate 301 so that the tension spring 705 is in a stretched and stored state. Solid lubricating grease is coated between the inner wall of the square holes 701 and the outer surface of the U-shaped blocks 702. As the sliding plate 501 slides and extends along the bottom of the base plate 301 toward the side where the transformer module 200 tilts, the sliding plate 501 also moves the U-shaped stop 702, screw 703, screw 704, tension spring 705, and ball bearing 706 together through the square hole 701. The rotational characteristics of the ball bearing 706 can reduce the resistance of the U-shaped stop 702 sliding along the bottom of the base plate 301, thereby reducing the sliding resistance of components such as the side support square tube 503 and the sliding plate 501, so as not to affect the side support square tube. The side support tube 503 is ejected at the speed of the side tilting of the transformer module 200. When the side support tube 503 is fully extended, the U-shaped stop 702 slides to one end of the base plate 301 along with the slide plate 501. The tension spring 705, which is in a stretched and stored state, releases its rebound force, pulling the U-shaped stop 702 to slide upward along the inside of the square hole 701, so that the U-shaped stop 702 is blocked at the end of the base plate 301. This ensures that the extended side support tube 503 will not slide in the opposite direction, thereby providing a stable lateral support effect.

[0024] For further details, please refer to [link / reference]. Figure 12 As shown: Two symmetrical foot pedals 707 are fixedly installed on the U-shaped stop 702. The two foot pedals 707 are located at the ends of the slide plate 501, and the gap between the two foot pedals 707 is greater than the width of the wedge block 602, so as to ensure that the foot pedals 707 will not interfere with the wedge block 602 as the U-shaped stop 702 slides along the length of the bottom of the base plate 301. The top of each foot pedal 707 is provided with several anti-slip holes at equal intervals in both directions. After use, first unscrew the locking bolt 507, which was previously raised at one end, downwards along the inside of the Z-shaped sheet metal bracket 506. Then, by stepping on the top of the pedal 707, the U-shaped stop 702, which is blocking the end of the base plate 301, slides downwards along the inside of the square hole 701. The tension spring 705 is stretched again to accumulate elasticity. The downward sliding of the U-shaped stop 702 causes the ball 706 to move together to the bottom of the base plate 301. Then, the side support square tube 503, connecting plate 502, and sliding plate 501 can be pushed back to their original positions. Next, tighten the unscrewed locking bolt 507 again inside the Z-shaped sheet metal bracket 506. At this time, the two locking bolts 507 are inserted into the two ends of the locking groove 505, which can prevent the side support square tube 503 from sliding unnecessarily.

[0025] For further details, please refer to [link / reference]. Figure 11 As shown: The top of the locking bolt 507 is lower than the bottom of the U-shaped spring 606. Because the top of the locking bolt 507 is lower than the bottom of the U-shaped spring 606, during the sliding of the side support square tube 503 toward the side of the transformer module 200, while the energy storage groove 604, energy storage slider 605 and U-shaped spring 606 move together, the bottom of the U-shaped spring 606 will not contact the top of the locking bolt 507 near the side of the tilt, thus avoiding interference with the sliding of the side support square tube 503.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
