Description

Technical Field

[0001] This utility model relates to the field of substation protection technology, and in particular to a sunshade structure for outdoor substations. Background Technology

[0002] Outdoor transformers are exposed to the natural environment for extended periods, leading to a rapid increase in surface temperature, accelerated aging of insulation materials, and increased load on the cooling system. Their operational stability and lifespan are significantly affected by climatic conditions. This is particularly true in the Middle East, where extreme climates such as Oman and Saudi Arabia, characterized by high radiation, high temperatures (long-term ≥40℃), and strong sandstorms, pose severe challenges to transformers. Currently, natural ventilation or simple shade netting are commonly used for heat dissipation both domestically and internationally, but these methods cannot effectively address the problem of heat radiation from direct sunlight. Furthermore, traditional shading devices are mostly designed for buildings or low-voltage equipment, making it difficult to meet the protection requirements of high-voltage power equipment (≥400kV) under extreme weather conditions.

[0003] Although various types of transformer shading devices have been proposed both domestically and internationally, none can meet the requirements of extreme high temperatures in some regions. Existing technologies, such as the substation-based shading structure (publication number CN209129283U), include a substation and horizontal and vertical shading panels fixed to it. The horizontal shading panels are horizontally positioned around the substation floor slab. The vertical shading panels face the substation's exterior windows, and a ventilation duct is provided between them. This invention, combining horizontal and vertical shading panels, overcomes the shortcomings of using either type alone. It is effective at blocking sunlight at medium angles from oblique rays entering through windows, providing a more uniform shading effect. This reduces indoor solar radiation heat and lowers indoor air conditioning energy consumption, thus achieving energy conservation and emission reduction goals.

[0004] However, existing technologies suffer from low modularity, complex on-site installation, and difficult maintenance and replacement. Furthermore, existing technologies often use corrugated panels as the top structure of the sunshade structure. During installation, corrugated panels need to be spliced ​​together horizontally to ensure airtightness. In the assembly of sunshade devices, it is difficult to fix and splice the corrugated panels on the sloping top of the sunshade device. Moreover, the existing sunshade devices have limited structural stability after splicing. When affected by environmental factors such as strong winds, they are prone to structural instability and swaying, and in severe cases, they may even deform or collapse.

[0005] Therefore, it is necessary to invent an outdoor substation shading structure to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a sunshade structure for outdoor substations to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an outdoor substation sunshade structure, including vertical beams and steel beams, wherein the vertical beams are provided in two sets and are symmetrically distributed, and the steel beams are provided in multiple sets and are respectively connected to the top of multiple vertical beams, and multiple purlins are provided above the steel beams, and multiple corrugated plates are provided above the multiple purlins. A pressure plate is provided above each of the corrugated plates, and the pressure plate is located above the purlin. Two strip-shaped through slots are provided through the upper surface of the purlin. An inclined tie rod is provided through the interior of each of the two through slots. The top ends of the two inclined tie rods are respectively threaded to the two ends of the lower surface of the pressure plate. The bottom ends of the two inclined tie rods are threaded together to a lower support plate, which is located below the steel beam. A strip-shaped groove is provided through the middle of the lower support plate. Two positioning blocks are provided above the opening of the strip-shaped groove, and the two positioning blocks are respectively attached to the bottom ends of the two sides of the steel beam. A locking bolt is provided through the middle of each of the two positioning blocks, and the locking bolt is provided through the interior of the strip-shaped groove.

[0008] Preferably, the top end of the inclined tie rod is configured as a vertical structure relative to the corrugated plate, and the top end of the inclined tie rod passes through a through hole opened in the middle of the corrugated plate.

[0009] Preferably, a sealing gasket is sleeved on the top end of the inclined tie rod. The sealing gasket is located above the corrugated plate, and the cross-section of the sealing gasket is an inverted conical structure. An extension of an annular structure is fixed on the outside of the sealing gasket, and the cross-section of the extension is a semi-circular structure.

[0010] Preferably, an angle bracket is provided between the outer wall of the purlin and the upper surface of the steel beam, and the two sides of the angle bracket are respectively connected to the outer wall of the purlin and the upper surface of the steel beam by bolts.

[0011] Preferably, multiple diagonal braces are fixed between the multiple steel beams, and adjacent diagonal braces are symmetrically distributed.

[0012] Preferably, the outer walls of the multiple vertical beams are each equipped with multiple side beams, and the multiple side beams are arranged sequentially from bottom to top.

[0013] Preferably, multiple sets of reinforcing beams are fixedly installed on the outer side of each of the multiple side beams, and each set of reinforcing beams consists of two beams, which are arranged in a cross pattern.

[0014] The technical effects and advantages of this utility model are as follows: This utility model uses vertical beams, steel beams, and purlins to form the main frame of a sunshade structure. The steel beams and purlins form an "H"-shaped stable structure to improve the overall strength of the sunshade structure. A corrugated plate is set above the purlins to achieve the sunshade effect. A pressure plate is set above the corrugated plate, and a lower support plate is set below the steel beams. The pressure plate and the lower support plate are connected by diagonal tie rods. The two sets of triangular structures formed by the lower support plate, pressure plate, and diagonal tie rods can stably fix the corrugated plate above the purlins and also assist in fixing the purlins. Furthermore, when the diagonal tie rods are not locked, they can slide laterally along the through grooves on the purlins to facilitate the lateral movement of the corrugated plate during installation. Compared with the prior art, this technical solution can achieve rapid construction of the sunshade structure and ensure its stability after construction. 2. This utility model improves the structural strength of steel beams by setting diagonal bracing between multiple steel beams, forming an "X" shape with multiple sets of diagonal bracing. It also improves the lateral wind resistance of the sunshade structure by setting side beams on the outside of the vertical beams, forming an "H" shape with the vertical beams and side beams. Furthermore, it enhances the lateral wind resistance of the sunshade structure by setting reinforcing beams on the outside of the side beams, forming an "X" shape with the reinforcing beams, thus ensuring the stability of the device during use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-6 The outdoor substation sunshade structure shown includes vertical beams 1 and steel beams 2. The vertical beams 1 are provided in two sets and are symmetrically distributed. The steel beams 2 are provided in multiple sets and are respectively connected to the top of multiple vertical beams 1. Multiple purlins 3 are provided above the steel beams 2, and multiple corrugated plates 4 are provided above the multiple purlins 3. A pressure plate 5 is provided above each of the corrugated plates 4, and the pressure plate 5 is located above the purlin 3. Two strip-shaped through grooves 6 are provided through the upper surface of the purlin 3. An inclined tie rod 7 is provided through the interior of each of the two through grooves 6. The top ends of the two inclined tie rods 7 are respectively threaded to the two ends of the lower surface of the pressure plate 5. The bottom ends of the two inclined tie rods 7 are threaded together to install a lower support plate 8, and the lower support plate 8 is located below the steel beam 2. A strip groove 9 is provided through the middle of the lower support plate 8. Two positioning blocks 10 are provided above the opening of the strip groove 9, and the two positioning blocks 10 are respectively attached to the bottom ends of both sides of the steel beam 2. A locking bolt 11 is provided through the middle of each of the two positioning blocks 10, and the locking bolt 11 is provided through the interior of the strip groove 9. It should be noted that the two ends of the inclined tie rod 7 are respectively connected to the pressure plate 5 and the lower support plate 8 by nuts. The above connection method is a common method in the art and will not be described in detail here. The top end of the inclined tie rod 7 is designed to be perpendicular to the corrugated plate 4, and the top end of the inclined tie rod 7 passes through the through hole opened in the middle of the corrugated plate 4. A sealing gasket 12 is sleeved on the top end of the inclined tie rod 7. The sealing gasket 12 is located above the corrugated plate 4, and the cross section of the sealing gasket 12 is an inverted conical structure. An annular extension 13 is fixed on the outside of the sealing gasket 12, and the cross section of the extension 13 is a semi-circular structure. The sealing gasket 12 and the extension 13 are used to seal the holes opened on the corrugated plate 4. Furthermore, the inverted conical cross section of the sealing gasket 12 allows its protruding part to better fit the surface of the corrugated plate 4. In addition, the sealing gasket 12 and the extension 13 can play a flexible connection role to prevent the pressure plate 5 from squeezing the corrugated plate 4 and deforming it during the locking process. An angle bracket 14 is provided between the outer wall of the purlin 3 and the upper surface of the steel beam 2. The two sides of the angle bracket 14 are respectively connected to the outer wall of the purlin 3 and the upper surface of the steel beam 2 by bolts. Multiple diagonal bracing strips 15 are fixedly installed between multiple steel beams 2, with adjacent diagonal bracing strips 15 symmetrically distributed. Multiple side beams 16 are installed on the outer walls of multiple vertical beams 1, and the multiple side beams 16 are arranged sequentially from bottom to top. Multiple sets of reinforcing beams 17 are fixedly installed on the outer side of multiple side beams 16, with two reinforcing beams 17 in each set, and the two reinforcing beams 17 are arranged crosswise to form an "X" shape structure, which improves the connection strength between multiple side beams 16. It should be noted that baffles can be added to the outer side of the reinforcing beams 17 as needed to achieve side wind protection, or baffles can be omitted to ensure the heat dissipation efficiency of the transformer.

[0024] Working principle of this utility model: During assembly, multiple sets of vertical beams 1 and steel beams 2 are first combined. A vertical beam 1 is bolted to each end of the steel beam 2, forming a "∩" shape with two vertical beams 1 and one steel beam 2. These "∩" shapes are then placed in the substation installation area. Side beams 16 are then bolted to the outside of the vertical beams 1, allowing for connection and positioning between the multiple "∩" shapes. Multiple diagonal braces 15 are then staggered between the steel beams 2, forming the main frame structure. The diagonal braces 15 enhance the structural stability between the steel beams 2. Purlins 3 are then placed on top of the steel beams 2 and secured with angle brackets 14 and bolts. Finally, corrugated plates 4 are placed... Above the purlin 3, and at the overlapping position of the corrugated plate 4 and the purlin 3, a hole is drilled. The inclined tie rod 7 is passed through the through groove 6 on the purlin 3 and the through hole on the corrugated plate 4. The pressure plate 5 is placed above the corrugated plate 4 so that the top end of the inclined tie rod 7 passes through the corresponding hole on the pressure plate 5. A nut is screwed onto the top end of the inclined tie rod 7 to connect the inclined tie rod 7 and the pressure plate 5. A lower support plate 8 is placed below the steel beam 2, and the bottom end of the inclined tie rod 7 passes through the bottom end of the lower support plate 8. Then, the bottom end of the inclined tie rod 7 is connected to the lower support plate 8 with a nut. At this time, the pressure plate 5, the inclined tie rod 7 and the lower support plate 8 form a triangular structure on both sides of the steel beam 2. While tightening and fixing the corrugated plate 4 above the purlin 3, the connection stability between the purlin 3 and the steel beam 2 is further improved. During the fixing process of the corrugated plate 4, when the nut at the bottom of the tie rod 7 is not tightened, the lower support plate 8 can slide along the lower surface of the steel beam 2. At this time, the position of the lower support plate 8 is adjusted so that the lower support plate 8 drives the tie rod 7 and the corrugated plate 4 to slide horizontally. This allows the horizontal position of the corrugated plate 4 to be adjusted after the initial positioning of the corrugated plate 4, so that multiple corrugated plates 4 can be spliced ​​together. After the corrugated plate 4 is fixed, the positioning block 10 is fixed below the lower support plate 8 by the locking bolt 11. At this time, the positioning block 10 presses against the steel beam 2 to limit the lower support plate 8, thereby further improving the stability of the triangular structure formed by the lower support plate 8, the tie rod 7 and the pressure plate 5. It should be noted that the connection between the structures in this embodiment is through high-strength bolts. All components in this embodiment are steel structures. The surface of the steel structure can be sprayed with a rust-removing and anti-corrosion coating. The corrugated plate 4 in this embodiment adopts the corresponding structure in the prior art. It is produced by prefabrication. Its specifications, models and the processing of reserved holes are all customized according to the actual needs of the substation.
