Description

Technical Field

[0001] This application relates to the field of substation technology, and in particular to a support device for a prefabricated substation. Background Technology

[0002] Prefabricated substations, also known as prefabricated modular substations, are an important component of modern power systems. They are widely used in urban power grids, industrial and mining enterprises, residential communities, and other locations due to their compact structure, flexible layout, efficient operation, and convenient maintenance. Since prefabricated substations are typically installed on the ground, water or moisture can enter the substation when there is standing water, affecting the insulation of electronic components and circuits, and even corroding the enclosure, thus reducing the substation's lifespan. Therefore, designing support devices for prefabricated substations is particularly necessary.

[0003] Existing prefabricated substations are typically supported by support bases, which can be categorized into two types:

[0004] 1) A support block is used as the support base. Specifically, the box-type substation is installed on the upper surface of the support block to support the box-type substation. The support block has a certain weight, and the support block is installed together with the box-type substation before it leaves the factory. Therefore, it is relatively difficult to move or transport the box-type substation when adjusting its position.

[0005] 2) The support base is formed by welding or screwing multiple plates together. Welding is time-consuming and labor-intensive, and is not suitable for mass production. Furthermore, prolonged welding can produce harmful gases that pollute the environment. In addition, the screw-fixing method results in a small contact area between the plates, leading to poor stability of the support base. This means that the upper part of the prefabricated substation may sway under external forces or vibrations, potentially damaging the internal structure of the substation.

[0006] Based on this, this application proposes a support device for a prefabricated substation. Utility Model Content

[0007] This application provides a support device for a prefabricated substation to solve the technical problems described in the background section.

[0008] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0009] This application provides a support device for a prefabricated substation, comprising:

[0010] A support assembly includes a base plate and multiple upright plates; the multiple upright plates and the base plate enclose a rectangular space, and a box-type substation is installed on the top surface of the rectangular space;

[0011] Four reinforcing plates are respectively disposed at the four right angles of the inner bottom of the rectangular space to strengthen the connection between each pair of adjacent upright plates and between each pair of adjacent upright plates and the bottom plate.

[0012] An isolation plate is vertically disposed on the inner bottom surface of the rectangular space and is used to divide the rectangular space into a high-voltage space and a low-voltage space, the high-voltage space and the low-voltage space corresponding to the high-voltage room and the low-voltage room of the box-type substation, respectively.

[0013] Optionally, wiring through holes are provided on the inner bottom surface of both the high-pressure space and the low-pressure space. Optionally, multiple heat dissipation through holes are provided from top to bottom on at least one side wall of both the high-pressure space and the low-pressure space, and all of the multiple heat dissipation through holes are strip-shaped.

[0014] Optionally, the height of each of the multiple uprights is 35cm to 70cm.

[0015] Optionally, an inspection ladder corresponding to the door of the box-type substation is inclinedly provided on the side wall of the rectangular space.

[0016] Optionally, the top surface of the upright plate is provided with a mounting groove, and the bottom surface of the box-type substation is provided with a mounting plate that is compatible with the mounting groove. The mounting plate is embedded in the mounting groove and connected to the mounting groove by fasteners.

[0017] Optionally, the reinforcing plate is in the shape of an isosceles triangle and is welded to the base plate and between each pair of adjacent upright plates.

[0018] Optionally, the base plate is welded together with the upright plate and the two upright plates;

[0019] The base plate and the plurality of the vertical plates are all made of stainless steel.

[0020] Optionally, a protective layer is provided on the base plate and the plurality of upright plates;

[0021] The protective layer is made of anti-corrosion paint.

[0022] The support device for the prefabricated substation provided in this application forms a rectangular space by means of a base plate and upright plates. Reinforcing plates are installed at the four right angles of the bottom of the rectangular space, reinforcing each pair of adjacent upright plates and the connection between each pair of adjacent upright plates and the base plate. The prefabricated substation is then installed on the inner top surface of the rectangular space, thus preventing the prefabricated substation from directly contacting the ground. This minimizes the impact of ground water or moisture on the electronic components inside the prefabricated substation. Compared to existing support blocks or support bases formed by welding or screwing multiple plates, the support assembly of this application has a hollow structure, resulting in a lighter weight for both the assembled support assembly and the prefabricated substation, facilitating movement. The reinforcing plates further improve the stability of the entire support assembly. In addition, by setting up isolation plates to divide the rectangular space into high-voltage and low-voltage spaces corresponding to the high-voltage and low-voltage rooms of the prefabricated substation, the support components can provide separate high-voltage and low-voltage spaces for the prefabricated substation while supporting it. This ensures that the high-voltage and low-voltage rooms inside the prefabricated substation do not affect each other while the prefabricated substation is being supported, thus ensuring the normal operation of the prefabricated substation.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0030] refer to Figures 1 to 4 This application provides a support device for a prefabricated substation, comprising:

[0031] The support assembly 100 includes a base plate 101 and multiple upright plates 102. The multiple upright plates 102 and the base plate 101 enclose a rectangular space 200, and a prefabricated substation 300 is installed on the top surface of the rectangular space 200. Since the support assembly 100 is enclosed by the base plate 101 and multiple upright plates 102 and has a support space 200 inside, the weight of the entire support assembly 100 is relatively small, which makes the overall movement of the support assembly 100 and the prefabricated substation 300 after installation more convenient.

[0032] Four reinforcing plates 400 are respectively disposed at the four right angles of the inner bottom of the rectangular space 200 to strengthen the connection between each pair of adjacent vertical plates 102 and between each pair of adjacent vertical plates 102 and the base plate 101. The reinforcing plates 400 can be installed at the right angles of the inner bottom of the rectangular space 200 by welding to improve the stability of the support assembly 100, thereby ensuring the stability of the box-type substation 300 supported by the support assembly 100 during operation.

[0033] An isolation plate 500 is vertically disposed on the inner bottom surface of the rectangular space 200 and serves to divide the rectangular space 200 into a high-voltage space 201 and a low-voltage space 202. The high-voltage space 201 and the low-voltage space 202 correspond to the high-voltage compartment and the low-voltage compartment of the prefabricated substation 300, respectively. To ensure that the high-voltage space 201 and the low-voltage space 202 do not interfere with each other, the isolation plate 500 can be made of insulating material.

[0034] The support device for the prefabricated substation provided in this application forms a rectangular space 200 by means of a base plate 101 and upright plates 102. Reinforcing plates 400 are installed at the four right angles of the bottom of the rectangular space 200. These reinforcing plates 400 strengthen the connection between each pair of adjacent upright plates 102 and between each pair of adjacent upright plates 102 and the base plate 101. The prefabricated substation 300 is then installed on the inner top surface of the rectangular space 200, thus preventing the prefabricated substation 300 from directly contacting the ground. This minimizes the impact of ground water or moisture on the electronic components inside the prefabricated substation 300. Compared to existing support blocks that support the prefabricated substation 300 or support bases formed by welding or screwing multiple plates, the support component 100 in this application has a hollow structure, resulting in a lighter weight for both the support component 100 and the prefabricated substation 300 when installed together, facilitating movement. The reinforcing plates 400 also improve the stability of the entire support component 100. In addition, by setting up an isolation plate 500 to divide the rectangular space 200 into a high-voltage space 201 and a low-voltage space 202 corresponding to the high-voltage chamber and low-voltage chamber of the prefabricated substation 300, respectively, the support assembly 100 can provide separate high-voltage spaces 201 and low-voltage spaces 202 for the prefabricated substation 300 while supporting it. This ensures that the high-voltage chamber and low-voltage chamber within the prefabricated substation 300 do not affect each other while the prefabricated substation 300 is being supported, thus ensuring the normal operation of the prefabricated substation 300.

[0035] In some embodiments, reference Figure 3 and Figure 4 In this application, both the inner bottom surface of the high-voltage space 201 and the inner bottom surface of the low-voltage space 202 are provided with wiring through holes 2011. The wiring through holes 2011 are provided after the support assembly 100 supports the prefabricated substation 300, facilitating the connection of the buried wires in the prefabricated substation 300. Specifically, a portion of the buried wire is buried underground, while the portion above ground passes through the wiring through holes 2011 and extends into the high-voltage space 201 or low-voltage space 202 to connect with terminals and other components in the high-voltage or low-voltage compartment of the prefabricated substation 300. (To ensure that water or moisture from the ground seeps into the rectangular space 200 through the wiring through holes 2011 and affects the prefabricated substation 300, the wiring through holes 2011 are adapted to the outer diameter of the buried wire and are sealed.) In addition, there can be multiple wiring through holes 2011 corresponding to the high voltage space 201 and the low voltage space 202. The specific number of wiring through holes 2011 can be set according to the actual number of ground wires to be connected to the box-type substation 300. Therefore, this application does not make specific limitations on them here.

[0036] In some embodiments, reference Figure 1 and Figure 4In this application, at least one side wall of the high-pressure space 201 and the low-pressure space 202 is provided with a plurality of heat dissipation holes 2012 from top to bottom, and the plurality of heat dissipation holes 2012 are all strip-shaped.

[0037] In the above embodiments, to prevent water from the ground from entering the rectangular space 200 through the heat dissipation holes 2012 and causing the prefabricated substation 300 to become damp, the height of the lowest heat dissipation hole 2012 from the ground should be a safe height. That is, under normal circumstances, the height of the water on the ground is lower than the height of the heat dissipation hole 2012 from the ground. In other words, even if there is water on the ground, it will not enter the rectangular space 200 through the heat dissipation hole 2012. The multiple heat dissipation holes 2012 and each heat dissipation hole 2012 are strip-shaped to increase the heat dissipation efficiency of the high-voltage and low-voltage compartments of the prefabricated substation 300, corresponding to the high-voltage space 201 and low-voltage space 202, respectively. The number of heat dissipation holes 2012 can be set according to actual conditions; therefore, this application does not specifically limit it.

[0038] In some embodiments, the height of the multiple uprights 102 in this application is 35cm to 70cm. Since this application uses the support assembly 100 to support the prefabricated substation 300, the purpose is to prevent water or moisture from entering the prefabricated substation 300 and affecting the insulation of electronic components and circuits inside the prefabricated substation 300 in cases of ground flooding. To ensure that the support assembly 100 can prevent the above-mentioned situation after supporting the prefabricated substation 300, the support assembly 100 needs to have a certain height, that is, the uprights 102 in the support assembly 100 need to have a certain height. If the height of the uprights 102 is too low, the above-mentioned effect will not be achieved. If the height of the uprights 102 is too high, it will be inconvenient for staff to perform daily maintenance on the prefabricated substation 300. The uprights 102 being between 35cm and 70cm not only prevent water or moisture from entering the prefabricated substation 300, thus ensuring the insulation of electronic components and circuits inside the prefabricated substation 300, but also facilitate daily maintenance by staff.

[0039] In some embodiments, reference Figure 1 and Figure 3 In this application, a maintenance ladder 203 corresponding to the door of the box-type substation 300 is inclinedly provided on the side wall of the rectangular space 200.

[0040] In the above embodiments, the maintenance ladder 203 facilitates workers to climb the maintenance ladder 203 and open the box door of the prefabricated substation 300 to perform maintenance and other operations on the prefabricated substation 300.

[0041] In some embodiments, reference Figure 3In this application, the top surface of the upright plate 102 is provided with a mounting groove 204, and the outer bottom surface of the box-type substation 300 is provided with a mounting plate 301 adapted to the mounting groove 204. The mounting plate 301 is embedded in the mounting groove 204 and connected to the mounting groove 204 by fasteners 600. In order to ensure the heat dissipation efficiency of the heat dissipation through hole 2012, the inner bottom of the mounting groove 204 is higher than the height of the uppermost heat dissipation through hole 2012.

[0042] In the above embodiment, first threaded through holes are provided on both opposite side walls of the mounting groove 204, and second threaded through holes are provided on the mounting plate 301. The fastener 600 is a screw, which sequentially passes through one of the first threaded through holes, one of the second threaded through holes, and another first threaded through hole, thereby connecting the mounting plate 301 to the mounting groove 204. Furthermore, to ensure the stability of the connection between the mounting plate 301 and the mounting groove 204, there are multiple first threaded through holes and multiple second threaded through holes, each corresponding one-to-one with a different first threaded through hole.

[0043] In some embodiments, reference Figure 3 The reinforcing plate 400 in this application is an isosceles triangle and is welded to the base plate 101 and to each of two adjacent upright plates 102.

[0044] In the above embodiments, since the two sides of the isosceles triangle are equal, the reinforcing plate 400 can effectively strengthen the connection between each pair of adjacent upright plates 102 and between each pair of adjacent upright plates 102 and the base plate 101.

[0045] In some embodiments, reference Figure 4 In this application, the base plate 101, the upright plate 102, and the two upright plates 102 are all welded together, which can ensure the stability of the connection between the base plate 101, the upright plate 102, and the two upright plates 102.

[0046] In addition, the base plate 101 and the multiple upright plates 102 are all made of stainless steel. Stainless steel has excellent corrosion resistance, mechanical properties, easy cleaning, and aesthetics. The base plate 101 and the multiple upright plates 102 made of stainless steel can effectively support the prefabricated substation 300 and have a long service life.

[0047] In some embodiments, a protective layer is provided on the base plate 101 and the plurality of upright plates 102 in this application; wherein, the protective layer can protect the base plate 101 and the upright plates 102, and can ensure the service life of the base plate 101 and the upright plates 102.

[0048] In addition, the protective layer is made of anti-corrosion paint. The anti-corrosion paint can be applied to the outer surfaces of the base plate 101 and the multiple vertical plates 102 by means of spraying or other methods, which further improves the anti-corrosion performance of the base plate 101 and the multiple vertical plates 102.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
