Description

Technical Field

[0001] This application relates to the technical field of temporary prefabricated substations, and in particular to a vibration-damping and protective prefabricated substation for construction. Background Technology

[0002] For occasions requiring temporary power supply, such as construction sites, temporary prefabricated substations are typically used. These substations can provide power for specific needs (such as construction equipment like tower cranes and mixers) while also being easy to dismantle or relocate after the demand ends, without needing to be permanently retained.

[0003] One difference between temporary prefabricated substations and traditional prefabricated substations is that temporary prefabricated substations have a simpler structure, especially the base, to facilitate quick installation and dismantling. In related technologies, the base of a temporary prefabricated substation is typically constructed from ordinary channel steel, angle steel, and other steel materials welded into a frame structure to meet support and stability requirements. Traditional prefabricated substations, on the other hand, have a more complex base structure, ranging from integral to split bases, using materials such as hot-dip galvanized steel to ensure the base is not easily damaged.

[0004] The problem with this technology is that, for temporary transformer substations, the ground conditions at construction sites are often complex, potentially uneven or soft. If the temporary substation is placed on such ground, the vibrations generated by large construction machinery such as excavators and cranes during operation can affect the temporary substation, leading to accelerated wear and tear, loose connections between components, and potentially causing safety accidents. Utility Model Content

[0005] In order to reduce the vibration impact of large construction machinery on temporary box-type substations and ensure stable equipment operation, this application provides a vibration-damping and protective box-type substation for construction.

[0006] This application provides a construction-grade vibration-damping and protective box-type substation with the following technical solution:

[0007] A vibration-damping and protective prefabricated substation for construction includes a main body and a base. The base is fixed to a foundation support surface to provide support for the main body. A vibration-damping connection assembly is provided between the main body and the base. The vibration-damping connection assembly includes:

[0008] An upper support is fixed to the side of the main body facing the base, and the upper support has a through hole at its lower end;

[0009] The lower support is fixed to the side of the base facing the main body, and one end of the lower support extends into the through hole to form a buffer cavity between the lower support and the upper support.

[0010] The shock absorber is installed inside the buffer cavity and has one end fixed to the outer surface of the lower support and the other end fixed to the inner wall of the upper support.

[0011] Optionally, the base includes multiple crossbeams and longitudinal beams distributed in an alternating manner. Connecting portions are formed at the junctions of the multiple crossbeams and longitudinal beams. The lower support is fixed to the connecting portions by fasteners. Mounting portions are formed at both ends of the multiple crossbeams and longitudinal beams in their extending directions. The mounting portions are located on the outside of the main body and are used to connect the base and the foundation support surface.

[0012] Optionally, the mounting part is welded and fixed to the end face of the crossbeam and the longitudinal beam. An mounting groove is formed on the mounting part, which penetrates the upper surface of the mounting part. An anchor rod is provided in the mounting groove. An mounting hole is opened on the side of the mounting part that contacts the foundation support surface. The anchor rod extends into the foundation support surface through the mounting hole.

[0013] Optionally, each of the crossbeams and longitudinal beams is provided with a fastener at both ends. The fastener is installed at the opening of the mounting part and is adapted to the mounting groove. The fastener is movably connected to the mounting part so that the mounting groove can be closed or opened.

[0014] Optionally, the shock-absorbing connection assembly further includes a wear-resistant pad and a connecting sleeve. The connecting sleeve is threaded to one end of the lower support extending into the through hole. The wear-resistant pad is fixed to the connecting sleeve, and the inner wall of the upper support is in full contact with the upper surface of the wear-resistant pad.

[0015] Optionally, side plates extending towards the base are formed around the bottom of the main body, and the lower surface of each side plate is in full contact with the base to form a receiving groove between the base, the side plate and the main body. Multiple sets of shock-absorbing connecting components are provided and evenly distributed in the receiving groove.

[0016] Optionally, the base also includes multiple outer protective plates, each of which is respectively disposed around the perimeter of the main body and connected to the bottom of the main body. The end of each outer protective plate away from the main body extends downward and contacts the foundation support surface.

[0017] Optionally, each of the outer protective plates is provided with an assembly groove that matches the crossbeam and the longitudinal beam, so that the outer protective plate can slide along the extension direction of the crossbeam and the longitudinal beam, and the two adjacent outer protective plates can be detachably connected.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By setting up shock-absorbing connection components between the bases, with the cooperation of the upper support, shock absorber and lower support, when the transformer receives internal or external vibration, the vibration energy is absorbed or dissipated by the shock absorber, reducing the vibration transmission to the foundation support surface, avoiding rigid collision between the main body and the base, thus making the operation of the main body more stable.

[0020] 2. By using side panels and outer protective panels in combination, sufficient space is created between the base and the main body to accommodate and protect the shock-absorbing connection components. The outer protective panel can isolate external debris and improve the overall protective performance of the equipment. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a vibration-damping and protective prefabricated substation for construction. (Refer to...) Figure 1A construction-grade vibration-damping and protective prefabricated substation comprises a main body 1, a base 2, and a vibration-damping connection assembly 3 disposed between the two. The base 2 is fixed to a foundation support surface, such as the ground at the construction site. The main body 1 is movably connected to the base 2 via the vibration-damping connection assembly 3. When large machinery at the construction site operates and generates vibration, the vibration is transmitted to the vibration-damping connection assembly 3 through the base 2. The vibration-damping connection assembly 3 absorbs or dissipates the vibration energy, thereby preventing rigid collisions between the main body 1 and the base 2 and avoiding problems such as loosening of the connection between the main body 1 and the base 2. Simultaneously, the vibration generated by the electrical equipment within the main body 1 during operation can be transmitted to the vibration damper 33 through the main body 1, preventing wear between the electrical equipment and the main body 1 and ensuring stable equipment operation.

[0029] The main body 1 adopts a modular structure, with the enclosure and its internal electrical equipment, such as high-voltage switchgear, transformer, and low-voltage switchgear, combined in one enclosure. Its specific structure and arrangement are well-known technologies to those skilled in the art and are not specifically limited here.

[0030] Reference Figure 2 and Figure 3 The base 2 is constructed by interlacing and welding multiple horizontal beams 21 and vertical beams 22. The horizontal beams 21 and vertical beams 22 are vertically distributed, forming a grid-like frame support structure. A connection point, i.e., a cross node, is formed at the intersection of each horizontal beam 21 and vertical beam 22. The lower end of the shock-absorbing connection component 3 is fixed to the connection point to ensure uniform load distribution. Preferably, both the horizontal beams 21 and vertical beams 22 are made of hot-dip galvanized channel steel or I-beams to ensure good corrosion resistance and adaptability to the humid environment of the construction site.

[0031] Furthermore, each longitudinal beam 22 and transverse beam 21 extends to form a mounting portion 23 at both ends. The mounting portion 23 is located on the outside of the main body 1, and a through mounting groove is formed on the upper surface of the mounting portion 23, thus forming a U-shaped plate structure. Anchor rods 4 are installed in the mounting groove. A mounting hole is formed on the bottom surface of the mounting portion 23. The anchor rod 4 passes through the mounting hole and is inserted into the foundation support surface. The base 2 is rigidly connected to the foundation by bolts. Preferably, the mounting portion 23 is fixed to the transverse beam 21 / longitudinal beam 22 by welding to ensure the connection strength. Preferably, there are two transverse beams 21, both extending along the length direction of the main body 1 and spaced apart in the width direction of the main body 1, preferably symmetrically arranged along the centerline of the width direction of the main body 1. Preferably, there are three longitudinal beams 22, all extending along the width direction of the main body 1 and spaced apart in the length direction of the main body 1.

[0032] In addition, to protect the anchor rod 4 and prevent the joint between the bolt and the anchor rod 4 from long-term exposure to the external environment and corrosion, which would affect subsequent dismantling work, a fastener 5 is installed at the opening of the mounting groove of the mounting part 23. The fastener 5 is made of a metal cover plate, adapted to the shape of the mounting groove and movably connected to the mounting part 23, so that the fastener 5 can slide or reverse to cover the mounting groove and prevent soil and rainwater from entering. The specific usage steps are as follows: when installing the base 2, open the fastener 5, insert the anchor rod 4 and fix it; after installation, close the fastener 5 to ensure that the surface of the mounting part 23 is flat.

[0033] Side plates 6 extend downwards from the bottom of the main body 1. The side plates 6 are formed by bending metal plates. The lower surface of the side plates 6 contacts the upper surface of the base 2. A receiving groove is formed between the four side plates 6, the main body 1, and the base 2. The aforementioned shock-absorbing connecting assembly 3 is set in the receiving groove.

[0034] Reference Figure 4 The damping connection assembly 3 includes an upper support 31, a lower support 32, and a damper 33. The upper support 31 is welded or bolted to the bottom surface of the main body 1, and is in the shape of a hollow column. A through hole is opened at the lower end, and the diameter of the through hole is larger than the outer diameter of the lower support 32. The lower support 32 is fixed to the connecting part of the base 2, and its upper end extends into the through hole of the upper support 31 in a platform shape, forming a buffer cavity with the inner wall of the upper support 31. The damper 33 is disposed in the buffer cavity, with one end fixed to the outer surface of the lower support 32 by bolts, and the other end fixed to the inner wall of the upper support 31. When the main body 1 or the base 2 transmits vibration to the damper 33, multiple dampers 33 work together to absorb or dissipate the vibration energy, thereby achieving the purpose of vibration damping.

[0035] Furthermore, to reduce frictional loss and improve the support effect of the base 2 on the main body 1, the shock-absorbing connection assembly 3 is further provided with a wear-resistant pad 34 and a connecting sleeve 35. The connecting sleeve 35 is screwed to the top of the lower support 32, and the wear-resistant pad 34 is fixed to the upper surface of the connecting sleeve 35, making close contact with the inner wall of the upper support 31 to form sliding friction, thus avoiding noise and wear caused by direct metal-to-metal friction. Preferably, the wear-resistant pad 34 is made of polytetrafluoroethylene or stainless steel.

[0036] Understandably, to prevent excessive compression or stretching of the shock absorber 33, a limiting flange can be provided on the inner wall of the through hole of the upper support 31, and a limiting step can be provided on the top of the lower support 32, thereby limiting the relative displacement between the upper support 31 and the lower support 32, and thus ensuring that the relative displacement between the main body 1 and the base 2 is within a safe range. The specific settings of the limiting flange and limiting protrusion are not shown in the attached drawings and adopt conventional technology, which will not be described in detail here.

[0037] Reference Figure 1An outer protective plate 24 is provided around the base 2. The outer protective plate 24 is a metal plate or a composite material plate, covering the gap between the bottom of the main body 1 and the base 2. The lower end of the outer protective plate 24 extends to the foundation support surface to form a complete protective shell. The outer protective plate 24 is preferably designed with a hollow structure to facilitate heat dissipation from the bottom of the main body 1. The outer protective plate 24 has mounting grooves that are compatible with the crossbeams 21 and longitudinal beams 22, so that the outer protective plate 24 can be slidably installed along the extension direction of the crossbeams 21 / longitudinal beams 22. Adjacent outer protective plates 24 can be detachably connected by bolts, clips, or overlapping, which facilitates on-site assembly and disassembly.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
