Description

Technical Field

[0001] The utility model relates to the technical field of transformer substations, in particular to a box-type transformer substation. Background Art

[0002] The substation wall mainly plays the role of defense and isolation. From the perspective of defense, the substation wall mainly prevents animals of all sizes from entering the substation to avoid damage to electrical equipment and accidents; it also prevents non-staff members who do not understand the dangers of high voltage from entering the substation and causing damage to equipment and personnel; from the perspective of isolation, the substation wall can play a certain role in blocking the noise inside the substation from spreading outside the station.

[0003] The existing substation walls mainly include brick walls, concrete walls and light steel keel partition systems.

[0004] Among them, brick wall is a common partition material, which is built with bricks. Because bricks have the characteristics of pressure resistance and fire resistance, they can well isolate the noise and radiation of power distribution equipment and ensure the safety of personnel. However, the construction cost is high and the construction period is also long.

[0005] Concrete walls can be constructed in the form of slabs, reinforced concrete, precast concrete, etc. according to specific conditions, and are used to build rooms, walls and other structures of substations. Concrete walls have the advantages of high strength, sound insulation, and strong heat insulation capabilities, but they also have problems such as high cost and long construction period.

[0006] The light steel keel partition system is built with light steel keels and gypsum boards. The light steel keel partition is easy to install. It does not require wall construction. It only needs to install keels, boards, etc., which saves the work of plasterers and bricklayers, saving time and labor costs. At the same time, the light steel keel partition is detachable and movable. It can be disassembled or moved at any time without causing damage to the structure. However, compared with solid walls, light steel keel partitions have poor sound insulation performance and there will be problems with noise transmission. At the same time, light steel keel partitions are a light structure with limited load-bearing capacity. It is not suitable for hanging heavy objects or wall decoration through fixings, which can easily cause the wall to loosen and affect the overall appearance.

[0007] Disadvantages of existing technologies: Currently commonly used substation walls either have a long construction period and high labor costs, or have poor sound insulation and insufficient load-bearing capacity. Utility Model Content

[0043] The utility model is further described below in conjunction with embodiments and drawings.

[0044] like Figures 1 to 5 As shown, a box-type substation includes a frame body 1, the frame body 1 is a hollow structure, and modular walls A are installed on the front, rear, left and right sides of the frame body 1, wherein at least one modular wall A is openable and closable and is configured as a box door, and a roof cover assembly B is installed on the top of the frame body 1. In this embodiment, the modular wall A includes a mounting frame 2 and a wall assembly 3 arranged inside the mounting frame 2, and the roof cover assembly B includes a roof frame 4 and a wall assembly 3 arranged inside the roof frame 4. The wall assembly 3 is a layered structure, including an outer wall layer 3a, an inner wall layer 3b, and a metal shielding mesh layer 3c arranged between the outer wall layer 3a and the inner wall layer 3b, and both the outer wall layer 3a and the inner wall layer 3b are calcium silicate boards.

[0045] With such a design, the construction of a box-type substation can be realized by installing modular walls A around the frame body 1 and installing a roof cover assembly B on the top of the frame body 1. The wall assembly 3 adopts a three-layer structure design, which ensures that the box-type substation structure is more solid.

[0046] In this embodiment, the modular wall A can be used as the side wall and window of the box-type substation in addition to being used as the door body of the box-type substation.

[0047] like Figure 2 , Figure 3 and Figure 6As shown, a slot 2a is formed on the inner side of the mounting frame 2, and the wall assembly 3 is embedded in the slot 2a. In this embodiment, in order to ensure that the wall assembly 3 is installed more firmly, screws are also inserted between the wall assembly 3 and the mounting frame 2 for fastening. A mounting hole 2b is formed at one end of the mounting frame 2 and passes through along its length direction. The mounting hole 2b is mainly used to insert a pin 5 for rotating and assembling the mounting frame 2. A positioning portion 1a is extended on the frame body 1, and a positioning hole 1a1 is provided on the positioning portion 1a. The other end of the pin 5 is inserted in the positioning hole 1a1, so that the modular wall A can be rotatably installed when used as a door body or frame body of a box-type substation. In this embodiment, the upper and lower ends of the mounting hole 2b are respectively penetrated with a pin 5. At this time, one end of the pin 5 is fixedly connected to the mounting hole 2b or the positioning portion 1a in a selective manner to ensure that the modular wall A can be rotatably installed. In addition, only one pin 5 can be inserted inside the mounting hole 2b, and at this time, the two ends of the pin 5 are respectively inserted in one positioning hole 1a1.

[0048] For example Figure 7 As shown, a connecting structure 2c is formed on the outer side of the installation frame 2, and the connecting structure 2c is used to connect adjacent modular walls A. When two adjacent modular walls A are used as doors or windows of a box-type substation, the connecting structure 2c helps the doors or windows to close more tightly.

[0049] like Figure 8 As shown, a hollow rubber strip 12 is provided between the connecting structure 2c and the mounting hole 2b. The hollow rubber strip 12 is fixed and glued to the connecting structure 2c or the mounting hole 2b in one of the following ways. When the door or window of the box-type substation is in a closed state, the hollow rubber strip 12 can be in a compressed state, so that the door or window can be closed more tightly and have better sealing performance.

[0050] like Figure 4 and Fig.16 As shown, a plurality of rectangular openings are distributed on the roof frame 4, and the inner layer of each rectangular opening is provided with a limiting groove 4a, and the wall assembly 3 is fixedly arranged in the limiting groove 4a. In this embodiment, three rectangular openings are distributed on the roof frame 4, and a wall assembly 3 is respectively installed in the three rectangular openings. In order to ensure that the roof cover assembly B has sufficient waterproof performance, in this embodiment, a sealing strip 6 is adhered between the roof frame 4 and the wall assembly 3, and the sealing strip 6 can ensure that the roof frame 4 and the wall assembly 3 are installed more tightly, and the sealing strip 6 also has a certain dustproof and heat-insulating effect.

[0051] like Figure 1 and Fig. 9As shown, the roof cover assembly B is circumferentially arranged with a drainage frame 7, the left, right and lower parts of the drainage frame 7 are all hollow structures, and the lower ends of the left, right and lower parts have inwardly folded parts 7a, a strip water trough is formed between the folded part 7a and the corresponding drainage frame 7, and the bottom array of the strip water trough is provided with drainage holes 7b; in this embodiment, the roof cover assembly B is obliquely installed on the top of the frame body 1, the left end, right end and lower end of the roof cover assembly B are all supported on the folded part 7a, and the left end, right end and lower end are all located above the strip water trough, so as to ensure that rainwater can flow to the inside of the drainage frame 7 instead of flowing along the wall of the substation and causing the wall of the substation to peel and rust.

[0052] like Fig.10 As shown, in this embodiment, the drainage frame 7 is assembled from four drainage frames 7d, and any two adjacent drainage frames 7d are fixedly connected by a connecting structure 13, so as to ensure the stability of the overall structure of the drainage frame 7.

[0053] Specifically, an inwardly folded support boss 7c is formed at the upper end of the drainage frame 7, and the upper end of the roof cover assembly B is supported on the support boss 7c, so as to ensure that the roof cover assembly B can be installed at an angle, thereby ensuring that rainwater can flow in a concentrated and directionally manner.

[0054] like Fig.11 As described above, a beam support frame 8 is installed between the frame body 1 and the roof cover assembly B, and the circumferential edge of the roof cover assembly B extends outwardly beyond the beam support frame 8. In this embodiment, the beam support frame 8 is a hollow structure, and the circumference of the beam support frame 8 is formed with array-distributed air holes 8a, which are used to connect the inside of the box-type substation with the outside. In this way, the gas exchange between the inside and outside of the box-type substation is ensured, thereby playing the role of cooling the inside of the box-type substation.

[0055] Specifically, the beam support frame 8 is assembled from a plurality of beam rods 8b. In this embodiment, the beam support frame 8 is assembled from ten beam rods 8b. Any two adjacent beam rods 8b are connected by a reinforcing plate 14. Fig.12 and Fig.13 As shown, the reinforcing plate 14 is a right-angled triangular plate, and both right-angled sides are folded to form a mounting portion 14a, and a through hole 14b is also formed on the mounting portion 14a. In this embodiment, the installation between the two beams 8b is achieved by installing bolts between the through hole 14b and the air vent 8a.

[0056] Further, such as Fig.12 and Fig.14As shown, an exhaust groove 9 is also provided on the top circumference of the frame body 1, and the bottom of the roof cover assembly B abuts against the top surface of the exhaust groove 9, so that a closed space is formed between the roof cover assembly B and the exhaust groove 9, and the air vent 8a is connected to the outside of the box-type substation through the exhaust groove 9. Fig.11 and Fig.15 In order to ensure that the exhaust groove 9 and the roof cover assembly B are installed more closely, a support baffle 9a adapted to the inclination angle of the roof cover assembly B is formed on the exhaust groove 9. An array of strip holes 9b are also formed at the bottom of the exhaust groove 9. The strip holes 9b help the internal gas of the box-type substation to be discharged outward. In addition, the strip holes 9b are arranged at the bottom of the exhaust groove 9 to prevent mosquitoes from entering.

[0057] Combination Fig.16 As shown, the air inside the box-type substation can flow into the exhaust groove 9 through the air holes 8a on the beam support frame 8 in the direction indicated by the arrow, and be discharged through the strip holes 9b.

[0058] like Fig.11 and Fig.18 As shown, a shutter assembly 10 is also provided on the modular wall A, and the shutter assembly 10 is also used for ventilation of the box-type substation. In this embodiment, shutter assemblies 10 are installed on both the upper and lower sides of the front and back of the box-type substation, and an exhaust fan 11 is also installed inside the box-type substation. The exhaust fan 11 can allow the gas outside the box-type substation to enter from the shutter assembly 10 on the lower side of the box-type substation, and the gas inside the box-type substation can be discharged from the shutter assembly 10 on the upper side of the box-type substation, so as to ensure the flow and exchange of air inside and outside the box-type substation, and then ensure the temperature and dryness inside the box-type substation. In addition, shutter assemblies 10 are also provided at the bottom of the left and right sides of the box-type substation to further ensure the ventilation function of the box-type substation.

[0059] like Fig.17 As shown, a condensate channel 4b is formed on the bottom surface of the roof frame 4 along the length direction. The condensate channel 4b is located above the exhaust groove 9. The condensate channel 4b can facilitate the discharge of condensate inside the box-type substation, and the condensate can be concentratedly discharged to the exhaust groove 9, so as to ensure the overall dryness of the inside of the box-type substation.

[0060] In this embodiment, the calcium silicate board of the outer wall layer 3a and the inner wall layer 3b is formed by mixing and rolling cement and calcium silicate. Compared with traditional cement walls and concrete walls, it has higher strength and strength, better stability, and does not require a large construction site and a long solidification time, and has lower production costs and higher efficiency. The metal shielding mesh layer 3c is composed of at least one layer of criss-crossed metal grids, which are parallel to the outer wall layer 3a and the inner wall layer 3b, and the metal grid is connected to a wire, which is directly connected to the installation frame 2 and the roof frame 4, so that the metal shielding mesh layer 3c can be shielded and grounded, thereby ensuring that the wall assembly 3 has a better shielding effect.

[0061] In addition, strong adhesive is filled between the outer wall layer 3a and the inner wall layer 3b, and the strong adhesive wraps the metal shielding mesh layer 3c. The strong adhesive not only ensures the overall firmness of the wall assembly 3, but also makes the wall assembly 3 have good sound insulation and shock absorption effects.

[0062] In this embodiment, a UV-printed exterior decorative layer is also attached to the outside of the exterior wall layer 3a by strong adhesive. The exterior decorative layer can be used to decorate the outer wall of the box-type substation, thereby improving the aesthetics of the wall of the box-type substation and achieving a decorative effect that matches the city or surrounding environment.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present invention.
