Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3, the present utility model discloses a wind-resistant structure for a prefabricated substation, including a first buckle plate 1, a press-and-release buckle plate 2, and a second buckle plate 3. One side of the first buckle plate 1 is provided with a first assembly buckle groove 11, and the other side of the first buckle plate 1 is provided with a first installation buckle groove 12. A first riveting hole 13 is opened on the first installation buckle groove 12. Both sides of the press-and-release buckle plate 2 are provided with connection buckle grooves 21. A guide sleeve 22 is inlaid on the connection buckle groove 21, and a strong spring 23 is sleeved on the guide sleeve 22. The connection buckle groove 21 on one side of the press-and-release buckle plate 2 is located in the first installation buckle groove 12, and the guide sleeve 22 on one side of the press-and-release buckle plate 2 is riveted and connected to the first riveting hole 13. One side of the second buckle plate 3 is provided with a second assembly buckle groove 31, and the other side of the second buckle plate 3 is provided with a second installation buckle groove 32. A second riveting hole 33 is opened on the second installation buckle groove 32. The connection buckle groove 21 on the other side of the press-and-release buckle plate 2 is located in the second installation buckle groove 32. The provided press-and-release buckle plate 2 is spliced with the first buckle plate 1 and the second buckle plate 3 through a buckle groove structure, and there is a clearance fit between the buckle grooves. The guide sleeve 22 on the press-and-release buckle plate 2 is used for riveting and fixing with the first buckle plate 1 and the second buckle plate 3, and a strong spring 23 is sleeved on the guide sleeve 22. When strong wind acts on the windward side of the prefabricated substation, the strong spring 23 on the press-and-release buckle plate 2 will be compressed, and the spring deforms within the gap of the buckle groove to absorb and consume energy, reducing the impact of the wind force on the direct action of the windward side and improving the wind resistance ability. Moreover, the guide sleeve 22 on the other side of the press-and-release buckle plate 2 is riveted and connected to the second riveting hole 33.

[0020] Specifically, the guide sleeves 22 are evenly distributed on the connection buckle groove 21, and the strong springs 23 are located in the connection buckle groove 21.

[0021] In this implementation scheme, the guide sleeve 22 is a connection structure, which is used for the installation between the press-and-release buckle plate 2 and the first buckle plate 1 and the second buckle plate 3, and is also used for the positioning and installation of the strong spring 23.

[0022] Specifically, the first riveting holes 13 are evenly distributed on the first installation buckle groove 12, and the connection buckle groove 21 on one side of the press-and-release buckle plate 2 has a clearance fit with the first installation buckle groove 12.

[0023] In this implementation scheme, the press-and-release buckle plate 2 is spliced with the first buckle plate 1 through the connection buckle groove 21 on one side of it and the first installation buckle groove 12.

[0024] Specifically, the second riveting holes 33 are evenly distributed on the second installation buckle groove 32, and the connection buckle groove 21 on the other side of the press-and-release buckle plate 2 has a clearance fit with the second installation buckle groove 32.

[0025] In this implementation scheme, the press-and-release buckle plate 2 is spliced with the second buckle plate 3 through the connection buckle groove 21 on the other side of it and the second installation buckle groove 32.

[0026] Specifically, clamping grooves 24 are provided at both ends of the pressing and releasing buckle plate 2, and a sealing strip 4 is clamped in the clamping grooves 24.

[0027] In this implementation scheme, the clamping groove 24 is an assembly structure for the installation and fixation of the sealing strip 4. The sealing strip 4 is a sealing material used to fill and seal the gaps of objects, and its main functions include sealing, heat insulation, sound insulation, waterproofing, dust prevention, and fixation, etc.

[0028] Specifically, a first positioning groove 14 is provided on the first installation buckle groove 12, and the sealing strip 4 at one end of the pressing and releasing buckle plate 2 is clamped in the first positioning groove 14.

[0029] In this implementation scheme, the sealing strip 4 is installed in the first positioning groove 14 and the clamping groove 24 to form a sealed connection between the pressing and releasing buckle plate 2 and the first buckle plate 1.

[0030] Specifically, a second positioning groove 34 is provided on the second installation buckle groove 32, and the sealing strip 4 at the other end of the pressing and releasing buckle plate 2 is clamped in the second positioning groove 34.

[0031] In this implementation scheme, the sealing strip 4 is installed in the second positioning groove 34 and the clamping groove 24 to form a sealed connection between the pressing and releasing buckle plate 2 and the second buckle plate 3.

[0032] During use, the pressing and releasing buckle plate 2 is spliced with the first buckle plate 1 and the second buckle plate 3 through a buckle groove structure, and the buckle grooves are in clearance fit. The guide sleeve 22 on the pressing and releasing buckle plate 2 is used for riveting with the first buckle plate 1 and the second buckle plate 3, and a strong spring 23 is sleeved on the guide sleeve 22 with a spring constant > 4.81 N / mm. We assume that the wind speed of strong wind is uneven. When strong wind acts on the windward side of the prefabricated substation as an accelerating force, it will compress the strong spring 23 on the pressing and releasing buckle plate 2, and the deformation in the clearance of a set of buckle grooves will slow down the pressure. When the wind speed decelerates, the strong spring 23 of the pressing and releasing buckle plate 2 will release to offset part of the acting force, thereby reducing the direct impact of wind force on the windward side.

[0033] To sum up, for the wind-resistant structure of the prefabricated substation, the provided pressing and releasing buckle plate 2 is spliced with the first buckle plate 1 and the second buckle plate 3 through a buckle groove structure, and the buckle grooves are in clearance fit. The guide sleeve 22 on the pressing and releasing buckle plate 2 is used for riveting with the first buckle plate 1 and the second buckle plate 3, and a strong spring 23 is sleeved on the guide sleeve 22. When strong wind acts on the windward side of the prefabricated substation, it will compress the strong spring 23 on the pressing and releasing buckle plate 2, and the spring will deform in the clearance of the buckle groove to absorb and consume energy, reducing the direct impact of wind force on the windward side and improving the wind-resistant ability.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
