Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, and in particular to a prefabricated substation that is easy to transport. Background Technology

[0002] A prefabricated substation, also known as a box-type substation, is a substation structure that combines high-voltage switchgear, low-voltage switchgear, power metering equipment, and reactive power compensation equipment inside a substation enclosure, while installing the transformer outside the enclosure and assembling them together in advance.

[0003] A search revealed a prefabricated substation disclosed in patent document CN202222163989.0, whose main structure includes a base and a transformer chamber, a high-voltage cabinet, and a low-voltage cabinet installed on the base; the base is provided with several first fixing structures for fixing the transformer chamber, high-voltage cabinet, and low-voltage cabinet of different specifications respectively.

[0004] Compared to traditional substations, this system features several primary fixed structures on the base, allowing users to select and install transformer rooms, high-voltage switchgear, and low-voltage switchgear according to their installation and usage needs. It can be adapted to the installation locations of transformer rooms, high-voltage switchgear, and low-voltage switchgear of different specifications. By independently manufacturing, selling, and installing the base, transformer room, high-voltage switchgear, and low-voltage switchgear, it improves the flexibility for users in the installation and use of substations.

[0005] While this prefabricated substation structure improves installation efficiency, the typically large size of the substation necessitates transportation to the target location after complete prefabrication. The transportation of such large prefabricated structures presents the following challenges:

[0006] First, larger substations have a higher center of gravity, making them prone to significant swaying and tipping during transport by vehicles, especially on bumpy roads, where stability is difficult to maintain.

[0007] Secondly, larger substations have difficulty passing through height-restricted passages when being transported by vehicles, which severely limits the diversity of transportation routes, increases transportation difficulties and costs.

[0008] In summary, it can be seen that existing prefabricated substations have certain shortcomings in the entire transportation process. Based on this, this utility model optimizes and improves existing prefabricated substations, and designs a prefabricated substation that is easy to transport. Summary of the Invention

[0009] To solve one of the aforementioned technical problems, the present invention adopts the following technical solution: a prefabricated substation that is easy to transport, comprising an assembled substation enclosure assembly, wherein primary and secondary equipment are prefabricated inside the substation enclosure assembly, a flip-angle seat is installed on the top of the substation enclosure assembly, a transformer unit is installed on the top of the horizontal section of the flip-angle seat, a high-strength hinge shaft is provided at the left end of the flip-angle seat, and fixing lugs are fixedly installed on the top of the substation enclosure assembly at both ends of the high-strength hinge shaft, with both ends of the high-strength hinge shaft movably inserted into the rotating holes of the fixing lugs, and a plurality of locking pin mechanisms for locking the flip-angle seat are installed on the upper right side wall of the substation enclosure assembly.

[0010] In any of the above embodiments, it is preferred that when the prefabricated substation is in operation, the upper end of the locking pin mechanism extends above the horizontal section of the flip-corner seat and locks the right side of the horizontal section of the flip-corner seat.

[0011] In any of the above embodiments, it is preferred that the flip-corner seat includes a horizontal section and a vertical section is provided at the top right side of the horizontal section. The upper end of the vertical section is folded horizontally to the left to form a fixing part. When the prefabricated substation is in working condition, the fixing part abuts against and is fixed to the bottom of the carriage of the transport vehicle.

[0012] In any of the above embodiments, it is preferred that a strong magnetic block is fixedly installed in a groove in the plane of the fixed part facing the bottom of the carriage of the transport vehicle, and the strong magnetic block is attracted and fixed to the bottom of the carriage of the transport vehicle.

[0013] In any of the above embodiments, it is preferred that the locking mechanism includes two fixing frames that are horizontally fixedly installed on the upper part of the inner and outer sides of the right side wall of the substation box assembly. Vertically arranged locking electric cylinders are bolted to the inner side of the two fixing frames respectively. The upper outer side wall of the piston rod of each locking electric cylinder is provided with external threads. The upper part of the piston rod of each locking electric cylinder passes through the through hole at the horizontal section of the flip-angle seat at its corresponding position and extends above it to cooperate with the locking nut. The bottom of each locking nut abuts against the top of the horizontal section.

[0014] In any of the above embodiments, it is preferred that the locking electric cylinder applies downward pressure to cause the locking nut to press downward against the top of the horizontal section.

[0015] In any of the above schemes, it is preferred that the number of strong magnetic blocks is N, where N is a natural number ≥ 2.

[0016] In any of the above schemes, it is preferred that two adjacent strong magnetic blocks are spaced apart.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The prefabricated substation in this utility model is an optimization and improvement based on the existing prefabricated substation technology. The transformer part adopts a detachable and flip-type structure, which ensures the rapid conversion between the transportation state and the working state of the substation, and effectively ensures the convenience and safety of the prefabricated substation when it is transported to the target location.

[0019] 2. In operation, the prefabricated substation remains fixed in its installation state, and the locking pin mechanism on its top can fix the transformer unit, effectively ensuring the stability of the entire substation structure.

[0020] 3. During transport, the transformer unit is rotated 90° and then fixed to the carriage by the strong magnetic block of the fixing part.

[0026] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-3 As shown in the image.

[0027] Example 1: A prefabricated substation that is easy to transport includes an assembled substation enclosure assembly 1. Primary and secondary equipment are pre-installed inside the substation enclosure assembly 1. A flip-corner seat 2 is installed on the top of the substation enclosure assembly 1. An existing transformer unit 3 is installed on the top of the horizontal section 201 of the flip-corner seat 2. A high-strength hinge shaft 4 is provided at the left end of the flip-corner seat 2. Fixed lugs 5 are fixedly installed on the top of the substation enclosure assembly 1 at both ends of the high-strength hinge shaft 4. The two ends of the high-strength hinge shaft 4 are movably inserted into the rotating holes of the fixed lugs 5. Several locking pin mechanisms for locking the flip-corner seat 2 are installed on the upper right side wall of the substation enclosure assembly 1.

[0028] The flip-angle base 2 of the prefabricated substation design in this utility model, which is easy to transport, adopts a left-end fixed-axis movable hinge and a right-end pin connection to ensure its stability in the normal installation state. At the same time, it can also ensure that after pre-assembly and during factory transportation, it is flipped 90° and fixed flat on the transport carriage 6, which greatly reduces the height of the center of gravity of the entire structure and effectively improves the stability of the entire substation structure during transportation.

[0029] In any of the above embodiments, it is preferred that when the prefabricated substation is in operation, the upper end of the locking pin mechanism extends above the horizontal section 201 of the flip-corner seat 2 and locks the right side of the horizontal section 201 of the flip-corner seat 2.

[0030] After the locking pin mechanism extends upward, it can lock the horizontal section 201 of the flip angle seat 2, ensuring that the horizontal section 201 of the flip angle seat 2 remains fixed. At this time, the left side of the horizontal section 201 of the flip angle seat 2 also remains fixed under the constraint of the high-strength hinge shaft 4. Therefore, the entire flip angle seat 2 can be effectively fixed. After the final installation is completed, the flip angle seat 2 can be tightened and fixed to the substation box assembly 1 again by simple bolt reinforcement.

[0031] In any of the above embodiments, it is preferred that the flip-corner seat 2 includes a horizontal section 201, and a vertical section 202 is provided on the top right side of the horizontal section 201. The upper end of the vertical section 202 is folded horizontally to the left to form a fixing part 203. When the prefabricated substation is in working condition, the fixing part 203 abuts against and is fixed to the bottom of the carriage 6 of the transport vehicle.

[0032] When the flip-angle seat 2 is on top of the substation box assembly 1, it is kept flat and fixed by the horizontal section 201. After flipping 90° to the left around the high-strength hinge shaft 4, it is abutted against the bottom of the carriage 6 of the transport vehicle by the vertical section 202 and the bottom fixing part 203, thereby ensuring the stability of the entire flip-angle seat 2 structure and the transformer unit 3 installed on it.

[0033] In addition, to further ensure the stability of transformer unit 3 during transportation, the vertical section 202 needs to be pressed against the side wall of carriage 6 to prevent lateral movement.

[0034] In any of the above embodiments, it is preferred that a strong magnetic block 7 is fixedly installed in a groove in the plane of the fixing part 203 facing the bottom of the carriage 6 of the transport vehicle, and the strong magnetic block 7 is attracted and fixed to the bottom of the carriage 6 of the transport vehicle.

[0035] When the bottom of the fixing part 203 abuts against the bottom of the carriage 6, in order to ensure that it does not shift to the side or in other directions, it is once again fixed and attracted to the bottom of the steel carriage 6 by the strong magnetic block 7.

[0036] Example 2: Compared with Example 1, this example also includes the following technical features:

[0037] In any of the above embodiments, it is preferred that the locking mechanism includes two fixing frames 8 that are respectively horizontally fixed on the upper part of the inner and outer sides of the right side wall of the substation box assembly 1. Vertically arranged locking electric cylinders 9 are respectively bolted to the inner side of the two fixing frames 8. The upper outer side wall of the piston rod of each locking electric cylinder 9 is provided with external threads 10. The upper part of the piston rod of each locking electric cylinder 9 passes through the through hole 12 at the horizontal section 201 of the flip angle seat 2 at its corresponding position and extends above it to cooperate with the locking nut 11. The bottom of each locking nut 11 abuts against the top of the horizontal section 201.

[0038] When the locking mechanism is working, the locking electric cylinder 9 is activated and its piston rod is controlled to extend upward. The top of the piston rod will extend above the horizontal section 201 of the flip angle seat 2, and then the corresponding locking nut 11 is installed and locked.

[0039] In any of the above embodiments, it is preferred that the locking electric cylinder 9 applies downward pressure to cause the locking nut 11 to press downward against the top of the horizontal section 201.

[0040] After the locking nut 11 is tightened, in order to ensure that the locking nut 11 is not rotated, the piston rod of the locking cylinder 9 needs to be controlled to return downward and apply pressure. At this time, the locking nut 11 and the horizontal section 201 will continue to be pressed together. Then, the locking cylinder 9 is controlled to stop rotating and lock in position, thereby ensuring the effective anti-disengagement treatment of the entire locking nut 11.

[0041] In any of the above schemes, it is preferred that the number of strong magnetic blocks 7 is N, where N is a natural number ≥ 2.

[0042] Selecting and setting multiple intervals of strong magnetic blocks 7 can effectively ensure the number of fixing points when the entire fixing part 203 comes into contact with the bottom of the carriage 6, improve the fixing effect, and prevent the phenomenon of warping and movement.

[0043] In any of the above schemes, it is preferred that two adjacent strong magnetic blocks 7 are spaced apart.

[0044] The spaced strong magnetic blocks 7 can better distribute the fixing points in multiple locations, thus improving the effect of multi-point fixing and adsorption.

[0045] Specific principle: The flip-angle base 2 of the prefabricated substation design in this utility model adopts a left-end fixed-axis movable hinge and a right-end pin connection to ensure its stability in the normal installation state.

[0046] At the same time, it can ensure that after pre-assembly and during factory transportation, it is rotated 90° and fixed flat on the transport carriage 6, which greatly reduces the height of the center of gravity of the entire structure and effectively improves the stability of the entire substation structure during transportation.

[0047] When the entire structure needs to be loaded into the cargo compartment 6 of the transport vehicle, in conjunction with lifting and pulling equipment, each locking nut 11 is removed beforehand, the locking cylinder 9 is returned to its original position, and the flip-angle seat 2 structure, on which the transformer unit 3 is installed, is flipped to the left, so that...

[0048] After rotating 90° around the high-strength hinge axis 4.

[0049] Then, the vertical section 202 and the bottom fixing part 203 abut against the bottom of the carriage 6 of the transport vehicle, thereby ensuring the stability of the entire flip-corner seat 2 structure and the transformer unit 3 installed on it.

[0050] After contact, the strong magnetic blocks 7 ensure the adsorption and fixation effect, preventing any shaking during transportation.

[0051] In summary, the prefabricated substation of this invention is an optimization and improvement upon existing prefabricated substation technologies. The transformer section adopts a detachable and flip-type structure, ensuring rapid conversion between transportation and operating states. This effectively guarantees the convenience and safety of transporting the prefabricated substation to its target location. In the operating state, the prefabricated substation remains fixed, and the locking pin mechanism on its top secures the transformer unit 3, effectively ensuring the stability of the entire substation structure. In the transportation state, the transformer unit 3 flips 90° and is fixed to the carriage 6 by the strong magnetic block 7 of the fixing part 203. This reduces the overall height of the structure in the transportation state and ensures that the structure maintains a low center of gravity and relative stability during transportation, reducing random swaying during transportation and ensuring transportation safety.
