Description

Technical Field

[0001] This utility model belongs to the technical field of power equipment, and in particular relates to an outdoor combined box-type substation. Background Technology

[0002] A modular prefabricated substation (also known as a European-style prefabricated substation) is a compact, complete power distribution unit that integrates a distribution transformer, low-voltage switchgear, power metering equipment, and reactive power compensation devices into one or more enclosures according to a specific wiring scheme. It is mainly used in urban high-rise buildings, rural buildings, residential communities, high-tech development zones, small and medium-sized factories, mines and oil fields, and temporary construction power supply locations, serving as a power distribution system for receiving and distributing electrical energy. These prefabricated substations are mostly used outdoors. Currently, most modular prefabricated substations are prefabricated and can be used after simple assembly upon arrival at the required location. However, in practical use, the following drawbacks still exist:

[0003] Firstly, the conventional European-style prefabricated substation's enclosure structure typically consists of three parts: a base, an outer shell, and a top cover. It possesses five protective functions: sun protection, rain protection, dust protection, rust protection, and prevention of small animals from entering. However, this type of structure is usually quite rigid and lacks structural strength. Furthermore, the outer shell is typically formed by several door panels or other enclosures, making it easily deformed under pressure. Whether during transportation or use, such as during construction, factors like work vehicles touching the outer shell can easily cause deformation. Damage to the outer shell is a minor issue, but it can easily lead to damage to the internal electrical equipment, thereby affecting the entire construction site. Therefore, it is necessary to strengthen the structure of the outer shell.

[0004] Secondly, an outdoor combined prefabricated substation with application number 202310534367.0 adopts a flexible movement and protection method to facilitate movement, avoid damage to the enclosure, and improve protection. However, the protection method it adopts is a three-sided enclosure structure, which is not comprehensive enough and still has protection defects. Moreover, the protection part does not come into contact with the main body of the prefabricated substation and cannot interact with each other, so the protection strength cannot be combined. Utility Model Content

[0005] The purpose of this utility model is to provide an outdoor modular box-type substation. By setting up columns, protective frames, door frames, sealing plates, bases, and guardrails, it solves the problems of insufficient structural strength, insufficient protective surface and protective effect of box-type substations, and the inability of protective components to be used in conjunction with box-type substations.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an outdoor combined box-type substation, including a base, guardrail, columns, roof, protective frame and sealing plate. Guardrails are provided at the four edges of the upper surface of the base. The guardrails include horizontal bars and vertical bars that are equidistant and fixed inside the horizontal bars. The bottom end of the vertical bars is fixed to the upper surface of the base.

[0008] The upper end of the base is also fixed with columns arranged in two rows and five columns in a rectangular pattern. Each of the two rows of columns has an L-shaped support block fixed on its opposite side. All the support blocks are supported by a protective frame, which is fitted over all the columns.

[0009] A sealing plate is inserted between each pair of columns in each column, and a door frame is fixed between each pair of columns in each row, with a door leaf installed inside the door frame.

[0010] Furthermore, a moisture-proof block is fixed to the bottom of the base, two protective railings are provided on each side of the upper end of the base, and one protective railing is provided on each end of the upper end of the base.

[0011] Furthermore, the outer periphery of the protective frame is fixed with threaded sleeves, and the number of threaded sleeves is twice that of the guardrail. Each crossbar of the guardrail is threaded with two long-neck bolts, the ends of which are screwed into the threaded sleeves adjacent to them.

[0012] Furthermore, all the aforementioned posts, door frames, and sealing panels are located within the enclosure of the guardrail, and the height of the vertical bars is lower than the height of the posts.

[0013] Furthermore, a hinge is fixed on the door frame, and the door leaf is hinged to the door frame via the hinge. The door frame is at the same height as the column, and a door lock is also installed on the door leaf.

[0014] Furthermore, each pair of columns in each column has a slot on its opposite side, and the sealing plate has a strip on both sides that matches the size of the slot. The sealing plate is inserted into the two slots and connected to the columns via the strip.

[0015] Furthermore, a top plate is fixed to the top of all the columns, and a canopy is fixed above the top plate. End plates are fixed between the two end edges of the top surface of the top plate and the inner arc surface of the canopy.

[0016] This utility model has the following beneficial effects:

[0017] This invention solves the problem of insufficient structural strength and easy deformation and damage of the outer shell of prefabricated substations by setting up columns, protective frames, door frames, sealing plates, and a base. It changes the conventional single-door panel assembly design (the conventional prefabricated substation shell is a rectangular structure composed of multiple door panels or door leaves), which has low structural strength and is prone to deformation. This invention uses multiple columns fixed to a base to form a rectangular structure, then inserts sealing plates between two columns in each column, and installs door frames between two columns in each row, with door leaves installed inside the door frames. Finally, a protective frame is installed over all columns for structural reinforcement, and a top plate is fixed to the top of all columns for integrated fixation. Multiple columns are used to strengthen key parts, and door leaves and sealing plates are no longer interconnected but connected to their corresponding columns, resulting in higher structural strength. The protective frames over the columns further strengthen the column structure.

[0018] This utility model solves the problems of insufficient protection surface and effect in prefabricated substations, and the inability of protective components to be used in conjunction with prefabricated substations, by setting up protective railings, columns, and protective frames. Multiple protective railings completely enclose the main body of the substation (the box-shaped structure formed by columns, sealing plates, and door panels), reducing protection defects. Even if there are external factors, the protective railings will bear the first layer of impact. Long-neck bolts are inserted in the crossbars of the protective railings and connected to the threaded sleeves outside the protective frame, making them connected as a whole. The protective frame is fitted over the columns, combining the main body of the substation with the protective part, making it more impact-resistant, better protective, and with a more complete protective surface.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Please see Figure 1-9 As shown, this utility model is an outdoor combined box-type substation, including a base 1, guardrail 2, column 3, roof 4, protective frame 5 and sealing plate 7. Guardrail 2 is provided at the four edges of the upper surface of the base 1. The guardrail 2 includes a horizontal bar 201 and vertical bars 202 that are equidistant and fixed inside the horizontal bar 201. The bottom end of the vertical bar 202 is fixed to the upper surface of the base 1.

[0033] The base 1 serves as the carrier and is located on the lower layer. The protective railing 2 is installed on the base 1 to protect the main body of the box-type substation.

[0034] The upper end of the base 1 is also fixed with two rows of five columns of rectangular columns 3. The opposite sides of the two rows of columns 3 are fixed with L-shaped support blocks 301, and all the support blocks 301 are supported by a protective frame 5, which is fitted over all the columns 3.

[0035] The main frame structure of the box-type substation is formed by fixing multiple rectangular columns 3 to the base 1. Support blocks 301 are then installed on the outside of all columns 3. The protective frame 5 is fitted over the columns 3 and placed on the support blocks 301 for support, which further strengthens the structural strength and improves the protective function.

[0036] A sealing plate 7 is inserted between each pair of columns 3 in each column, and a door frame 6 is fixed between each pair of columns 3 in each row, with a door leaf 601 installed inside the door frame 6.

[0037] The space between two columns 3 in each row is sealed off by the sealing plate 7, and the space between two columns 3 in each row is sealed off by the door frame 6 and the door leaf 601, thereby forming multiple compartments for installing different electrical equipment.

[0038] A moisture-proof block 101 is fixed at the bottom of the base 1, and two protective railings 2 are set on each side of the upper end of the base 1, and one protective railing 2 is set on each end of the upper end of the base 1.

[0039] The moisture-proof block 101 is made of moisture-proof material, which can be used to prevent moisture from entering the box and can also be used to raise it to a certain extent to prevent the box substation from being embedded too deep into the ground; it is also protected by multiple protective railings 2.

[0040] The outer periphery of the protective frame 5 is fixed with threaded sleeves 501, and the number of threaded sleeves 501 is twice that of the protective railing 2. Each horizontal bar 201 of the protective railing 2 is inserted with two long neck bolts 203, and the end of the long neck bolt 203 is screwed into the threaded sleeve 501 that is close to it.

[0041] The protective frame 5 is fitted over all the posts 3. Two long-neck bolts 203 are inserted into the crossbar 201 of each guardrail 2, and then screwed into the corresponding threaded sleeve 501, so that the guardrail 2 and the protective frame 5 are relatively fixedly connected and form an integral unit, which makes the protective effect better and the protective strength higher.

[0042] All posts 3, door frames 6, and sealing plates 7 are within the enclosure of guardrail 2, and the height of the vertical bar 202 is lower than the height of the post 3.

[0043] All the guardrails 2 form a rectangular enclosure, which encloses and protects the main body of the prefabricated substation.

[0044] A hinge is fixed on the door frame 6, and the door leaf 601 is hinged to the door frame 6 via the hinge. The door frame 6 is at the same height as the post 3, and a door lock is also installed on the door leaf 601.

[0045] The door leaf 601 is hinged to the door frame 6, which makes it easy to open, and the door frame 6 makes the door leaf 601 more stable.

[0046] Each column of two uprights 3 has a slot 302 on its opposite side. Both sides of the sealing plate 7 are provided with a strip that matches the size of the slot 302. The two sides of the sealing plate 7 are inserted into the two slots 302 and connected to the uprights 3 through the strip.

[0047] Insert the sealing plate 7 into the slot 302 using the clip, so that the sealing plate 7 does not need to be installed with the column 3 with any additional fasteners. The simple plug-in connection is sufficient for use, and no fasteners are required. After all the sealing plates 7 are plugged in, finally install the top plate 402.

[0048] All the columns 3 are fixed to the top of the top plate 402, and the canopy 4 is fixed above the top plate 402. The two end edges of the top surface of the top plate 402 and the inner arc surface of the canopy 4 are both fixed with end plates 401.

[0049] The top plate 402 is fixed to the top of all the columns 3, connecting all the columns 3 into a whole to form a rectangular frame. The ceiling 4 is also fixed above the top plate 402. The gaps on both sides of the ceiling 4 are fixed by the end plate 401. At this time, a heat insulation cavity is formed between the top plate 402, the ceiling 4 and the end plate 401 to isolate the entry of external heat as much as possible.

[0050] The specific working principle of this utility model is as follows: First, the base 1, as a carrier, is located in the lower layer. A moisture-proof block 101 is fixed at the bottom of the base 1, directly contacting the ground or foundation, which can be used for moisture prevention to avoid water vapor entering the box body, and can also be used to raise it to a certain extent to prevent the box-type substation from being embedded too deeply into the ground. Then, multiple rectangular columns 3 are fixed to the base 1 to form the frame structure of the main body of the box-type substation. Subsequently, a sealing plate 7 is inserted between each pair of columns 3 in each row. The sealing plate 7 is inserted into the slot 302 through the clip, so that the sealing plate 7 does not need to be installed with the column 3 with additional fasteners. A door frame 6 is fixed between each pair of columns 3 in each row. The door frame 6 and the door leaf 601 are used to close the gap between each pair of columns 3 in each row, thereby forming multiple compartments for installing different electrical equipment. Finally, the top plate 402 is welded and fixed. At the top of all columns 3, all columns 3 are connected as one to form a rectangular frame; then support blocks 301 are set outside all columns 3, and the protective frame 5 is fitted outside the columns 3 and placed on the support blocks 301 for support, further strengthening the structural strength; a canopy 4 is also fixed above the top plate 402, and the gaps on both sides of the canopy 4 are fixed by end plates 401 to form a heat insulation cavity, which isolates the entry of external heat as much as possible; finally, protective railings 2 are installed on the base 1, and all protective railings 2 form a rectangular enclosure space, which completely encloses the main part of the substation (the box formed by the columns 3, the sealing plate 7, and the door leaf 601) to reduce protection defects. Two long neck bolts 203 are inserted into the crossbar 201 of each protective railing 2, and then screwed into the corresponding threaded sleeve 501, so that the protective railing 2 and the protective frame 5 are relatively fixedly connected and formed as one.

[0051] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
