[0037] The application discloses a European box transformer top cover structure.

[0038] A European box transformer top cover structure is applied to the top of a European box transformer for covering the European box transformer.

[0039] Reference Figure 1 As shown in the drawings, it comprises a top frame 1, a horizontal main beam 2, a wedge-shaped cross beam 3, a wedge-shaped side plate 4 and a fixed cover plate 5; the top frame 1 is installed on the top of the European box transformer and has a width greater than that of the European box transformer; the top frame 1 is the main frame for providing support for the top cover; the top frame 1 is installed along the top of the European box transformer so that the stress of the top frame 1 is borne by the European box transformer; the top frame 1 can be a rectangular frame made of metal or plastic; the width of the top frame 1 is greater than that of the European box transformer, so that the top frame 1 can extend outwards in the width direction of the European box transformer to completely cover the European box transformer.

[0040] The horizontal main beam 2 is installed at both ends of the top frame 1 along the length direction of the European box transformer; the horizontal main beam 2 can be a rectangular plate beam and is located at the center point of each width side of the top frame 1 to ensure that the stress is balanced when providing support.

[0041] The wedge-shaped cross beam 3 is provided with a plurality of wedge-shaped cross beams arranged at intervals along the width direction of the top frame 1; the wedge-shaped cross beam 3 can form a wedge shape on its top surface; the wedge-shaped cross beam 3 is provided with a plurality of wedge-shaped cross beams; the two ends of the bottom of each wedge-shaped cross beam 3 are in contact with and fixedly installed on the top frame 1; meanwhile, the center of the wedge-shaped cross beam 3 is borne by the horizontal main beam 2; when the wedge-shaped cross beam 3 is stressed, the wedge-shaped cross beam 3 is subjected to pressure from top to bottom due to its wedge shape; the protrusion in the middle can improve the bearing capacity; the horizontal main beam 2 at the bottom provides bearing, thereby ensuring the stability and compression resistance of the whole wedge-shaped cross beam 3.

[0042] The wedge-shaped side plate 4 is provided with two groups of wedge-shaped side plates installed at both ends in the width direction of the top frame 1; the wedge-shaped side plate 4 is located at both width sides of the top frame 1 and serves as the cover on both sides of the complete top cover structure.

[0043] The fixed cover plate 5 is fixedly installed on the wedge-shaped side plate 4 and the top frame 1; the wedge-shaped cross beam 3 and the top frame 1 provide the bearing of the fixed cover plate 5; when the fixed cover plate 5 covers the wedge-shaped side plate 4, the top frame 1 and the wedge-shaped cross beam 3, the fixed cover plate 5 extends out of the European box transformer together with the top frame 1 to cover the whole European box transformer and form a complete top cover; meanwhile, the wedge-shaped design can facilitate the guidance of water flow, ensure the convenient flow of rainwater in rainy days, improve the waterproof performance and the beauty of the surface style, and improve the stable bearing of the structure by using the wedge-shaped side plate 4, the top frame 1 and the wedge-shaped cross beam 3 to provide the stable bearing of the fixed cover plate 5.

[0044] Further, referring to Figure 2 As shown, the fixed cover plate 5 includes a first inclined plate 51 and a second inclined plate 52; the first inclined plate 51 and the second inclined plate 52 are connected to each other at an inclined fixed angle, forming a cover plate in the shape of a "person" character. When the rain falls on the first inclined plate 51 and the second inclined plate 52, it can flow along the inclined surface, thereby providing the function of guiding and flowing the rainwater, and further ensuring stable waterproof performance.

[0045] The first inclined plate 51 and the second inclined plate 52 are connected to the wedge-shaped side plate 4 and the top frame 1 at one end away from the connection point, and the connection mode can be clamping or bolt locking to ensure the stability of the connection, while also being convenient to disassemble. The bottom surface of the first inclined plate 51 and the second inclined plate 52 is connected to the top surface of the wedge-shaped cross beam 3, and the connection mode can be abutting. The first inclined plate 51 and the second inclined plate 52 only need to be in contact with the top surface of the wedge-shaped cross beam 3, so that the force can be transmitted to the wedge-shaped cross beam 3 when stressed. At the time of disassembly, the first inclined plate 51 and the second inclined plate 52 can be directly removed, which is convenient for installation and disassembly.

[0046] Specifically, the first inclined plate 51 and the second inclined plate 52 utilize the person-shaped connection structure to conveniently guide and flow the rainwater, ensuring high waterproof performance, and through the connection with the wedge-shaped side plate 4, the top frame 1 and the wedge-shaped cross beam 3, the stability of the installation can be ensured.

[0047] Further, referring to Figure 2 As shown, the first inclined plate 51 and the second inclined plate 52 are provided with a bent end 53 at one end close to the top frame 1. The bent end 53 is bent along the top frame 1 and covers the side surface of the top frame 1 in the vertical direction. By covering the top frame 1 with the bent end 53 of the first inclined plate 51 and the second inclined plate 52, the first inclined plate 51 and the second inclined plate 52 completely cover the top frame 1, ensuring the overall appearance while covering the top frame 1 to reduce the water leakage at the connection point, further improving the waterproof performance.

[0048] Among them, the bent end 53 is bent inward toward the top frame 1, thereby wrapping the top frame 1 to improve the stability of the connection.

[0049] In some embodiments, referring to Figure 2 As shown, the first inclined plate 51 and the second inclined plate 52 are provided with a first cover plate 54 at the connection point. The first cover plate 54 is located on the same vertical straight line as the horizontal main beam 2. The first cover plate 54 covers the connection point of the first inclined plate 51 and the second inclined plate 52, which can ensure that the connection point of the first inclined plate 51 and the second inclined plate 52 will not appear the phenomenon of water leakage, further improving the waterproof performance of the top cover.

[0050] In some embodiments, referring to Figure 1 As shown in the figure, the fixed cover plate 5 is provided with a plurality of fixed cover plates 5, and the plurality of fixed cover plates 5 are spliced to form a complete top cover covering the top frame 1. The splicing of the plurality of fixed cover plates 5 into a complete top cover is to separate the originally complete top cover into several parts, so that when any fixed cover plate 5 is damaged, only the damaged fixed cover plate 5 needs to be replaced, without the need to replace the complete top cover, thereby achieving the effect of facilitating maintenance and replacement. The number of fixed cover plates 5 in this embodiment is taken as an example.

[0051] Further, referring to Figure 1 and Figure 3 As shown in the figure, the splicing points of the adjacent fixed cover plates 5 are provided with a second cover plate 55, which covers the splicing points of the adjacent fixed cover plates 5 to avoid water leakage.

[0052] The fixed cover plate 5 is provided with a bending piece 56 at one end close to the second cover plate 55, and the second cover plate 55 is provided with an inner groove 551. The fixed cover plate 5 is embedded in the inner groove 551 by the bending piece 56, so that the fixed cover plate 5 is clamped with the second cover plate 55 by the bending piece 56. The clamping condition can make the connection between the fixed cover plate 5 and the second cover plate 55 more stable and the structure more compact, so as to avoid the separation of the fixed cover plate 5 and the second cover plate 55 under the condition of collision or vibration.

[0053] Further, a sealing strip is arranged between the second cover plate 55 and the fixed cover plate 5, which covers the gap between the connection points of the second cover plate 55 and the fixed cover plate 5, thereby further improving the waterproof performance.

[0054] In some embodiments, referring to Figure 1 As shown in the figure, a reinforcing cross beam 6 is further arranged between the adjacent wedge-shaped cross beams 3. The reinforcing cross beam 6 can stabilize the wedge-shaped cross beam 3. The reinforcing cross beam 6 connects the adjacent wedge-shaped cross beams 3, so that when the wedge-shaped cross beam 3 is forced to fall to any side, it can be resisted by the reinforcing cross beam 6, thereby ensuring the stability of the installation of the wedge-shaped cross beam 3. At the same time, the reinforcing cross beam 6 can also cooperate with the wedge-shaped cross beam 3 to resist the first inclined plate 51 and the second inclined plate 52, and simultaneously provide the compression resistance and stability of the first inclined plate 51 and the second inclined plate 52.

[0055] In some embodiments, referring to Figure 1 As shown in the figure, a horizontal cover plate 7 is further arranged on the surface of the top frame 1. The horizontal cover plate 7 can cover the position below the wedge-shaped cross beam 3. The horizontal cover plate 7 can play a certain heat insulation role. After the sunlight is blocked by the fixed cover plate 5, the horizontal cover plate 7 is used as a second layer of heat insulation to avoid too much heat from being transferred to the European box transformer, thereby affecting the operation of the internal equipment.

[0056] In some embodiments, referring to Figure 1As shown, the side of the top frame 1 extends to the end away from the wedge-shaped cross beam 3 and is provided with an abutting part 11. The abutting part 11 is in the form of a U-shaped block structure. The main function is to fix the cover plate 5 to cover the top cover plate. The width of the cover plate 5 is greater than the width of the top frame 1. Therefore, the top frame 1 extends to the end away from the wedge-shaped cross beam 3. Therefore, the abutting part 11 connected with the top frame 1 is arranged to abut against the bottom of the cover plate 5. Thus, the end of the cover plate 5 away from the top frame 1 can be supported, thereby improving the stability of the overall structure.

[0057] The abutting part 11 can abut against the second cover plate 55 and simultaneously provide support for the second cover plate 55.

[0058] The embodiments of the present application are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same reference numerals are used to represent the same components. Therefore, equivalent changes made according to the structure, shape, principle of the present application should be included in the protection scope of the present application.
