[0049] When conventional wind power box-type substations are used, due to the large diameter and high height of conventional wind turbine blades, the blades are prone to ice and ice falling when not in operation, posing a danger to the box-type substation underneath. In order to protect the box-type substation from ice falling, conventional wind power box-type substations are usually protected from ice falling by building an anti-ice falling protection cover or protection pavilion, and placing the box-type substation in it to reduce ice falling damage, but this anti-ice falling protection method has a complex structure, and the disassembly and assembly process is cumbersome, which is extremely inconvenient.

[0050] In view of this, an embodiment of the utility model provides a top cover assembly and a box-type substation, which can effectively reduce the damage caused by ice falling from wind turbines to the box-type substation, and has a simple structure, is easy to disassemble, maintain and replace, and reduces on-site construction.

[0051] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0052] See also Figure 1 The top cover assembly 10 provided in the embodiment of the utility model is applied to a box-type substation 1, such as a box-type substation 1 for wind power. The box-type substation 1 comprises a box-type substation body 11 and the top cover assembly 10, wherein the top cover assembly 10 is connected to the top of the box-type substation body 11, so as to reduce the damage to the box-type substation 1 caused by ice falling from the wind turbine.

[0053] See also Figure 1 and Figure 2 The top cover assembly 10 includes a top cover 100, a reinforcing beam 200, a connecting piece 300 and an anti-ice falling plate 400. The top cover 100 is connected to the box transformer body 11. The reinforcing beam 200 is connected to the upper surface of the top cover 100. One end of the connecting piece 300 is connected to the reinforcing beam 200, and the other end is connected to the anti-ice falling plate 400.

[0054] The top cover assembly 10 provided by the embodiment of the utility model is provided with an anti-ice falling plate 400, which can receive ice falling from the fan blades to prevent the ice falling from the fan blades from directly damaging the box transformer body 11; and the reinforcing beam 200 is connected between the top cover 100 and the anti-ice falling plate 400, so that the structural strength is higher and the damage to the box transformer body 11 caused by the ice falling from the fan can be effectively reduced; in addition, due to the use of the connecting piece 300, the connection between the reinforcing beam 200 and the anti-ice falling plate 400 is realized, making the structure simpler, easy to disassemble, maintain and replace, and reducing on-site construction.

[0055] See also Figure 3 Furthermore, in this embodiment, in order to improve the overall strength of the top cover assembly 10, the top cover 100 adopts a double-layer structure. The top cover 100 includes an upper top cover plate 110, an inner reinforcement plate 120 and a lower top cover plate 130. Among them, the upper surface of the upper top cover plate 110 is connected to the reinforcement beam 200. The inner reinforcement plate 120 is connected between the upper top cover plate 110 and the lower top cover plate 130. The lower top cover plate 130 is connected to the box-type transformer body 11.

[0056] It should be noted that the upper top cover plate 110 and the lower top cover plate 130 can be considered to be stacked in parallel, and the two are connected by the inner reinforcement plate 120, so as to realize a double-layer top cover 100 structure to make the structure stronger. In addition, the anti-falling ice plate 400 can also be optionally stacked with the upper top cover plate 110 and the lower top cover plate 130, and can be arranged obliquely downward relative to the upper top cover plate 110, so as to form a three-layer structure of the anti-falling ice plate 400, the upper top cover plate 110, and the lower top cover plate 130 from top to bottom. When the fan blade falls on the anti-falling ice plate 400, the impact force is transmitted to the upper top cover plate 110, the inner reinforcement plate 120 and the lower top cover plate 130 through the anti-falling ice plate 400 and the reinforcement beam 200 in turn. Since the anti-falling ice plate 400, the upper top cover plate 110 and the lower top cover plate 130 form a three-layer structure, the structural strength is higher and it can better withstand the impact force of the falling ice on the fan blades, so that the falling ice on the fan blades will not damage the top cover assembly 10, and at the same time, it also protects the box transformer body 11 and the electrical equipment inside it.

[0057] Optionally, the upper cover plate 110 and the inner reinforcement plate 120 may be connected by fastening bolts, the inner reinforcement plate 120 and the lower cover plate 130 may be connected by fastening bolts, and the lower cover plate 130 may be connected to the box-type transformer body 11 by fastening bolts. This can ensure structural strength, facilitate assembly and disassembly of the cover 100, and reduce on-site construction.

[0058] See also Figure 3 and Figure 4 In addition, as an example, in this embodiment, the reinforcing beam 200 is welded to the upper surface of the top cover 100. This can make the connection between the reinforcing beam 200 and the top cover 100 more secure and stronger. Further, the reinforcing beam 200 is welded to the upper surface of the upper top cover plate 110.

[0059] See also Figure 4 and Figure 5 The reinforcing beam 200 is a hollow structure, and a through hole 210 communicating with the internal cavity of the reinforcing beam 200 is provided on one side wall of the reinforcing beam 200. One end of the connecting piece 300 is located in the internal cavity and connected to the reinforcing beam 200; the other end of the connecting piece 300 passes through the through hole 210 and protrudes from the reinforcing beam 200, and is connected to the anti-fall ice plate 400.

[0060] In this way, by pre-placing a portion of the connecting piece 300 into the internal cavity of the reinforcing beam 200 and connecting it to the reinforcing beam 200, after the reinforcing beam 200 is installed on the upper surface of the top cover 100, it is very convenient to connect the anti-ice falling plate 400 to the connecting piece 300, and it is convenient to disassemble and assemble the reinforcing beam 200 and the anti-ice falling plate 400.

[0061] Optionally, the reinforcing beam 200 adopts a profile structure with a rectangular cross section and a hollow interior, so that the connecting member 300 can pass through the through hole 210 and connect with the reinforcing beam 200. As an example, the connection between the connecting member 300 and the reinforcing beam 200 can be welded.

[0062] See also Figure 5 and Figure 6 In this embodiment, in order to facilitate the connection between the connector 300 and the reinforcing beam 200, the connector 300 may include a bolt 310 and a nut 320. The anti-falling ice plate 400 is provided with a through hole 410. The bolt 310 has a first end 311 and a second end 312 that are arranged opposite to each other. The first end 311 is located in the internal cavity and is connected to the reinforcing beam 200. The second end 312 passes through the through hole 210 and the through hole 410 in sequence and cooperates with the nut 320.

[0063] When the connector 300 is connected to the reinforcing beam 200, the first end 311 of the bolt 310 having the nut is placed in the internal cavity and connected to the reinforcing beam 200. As an example, the first end 311 is welded to the reinforcing beam 200 to facilitate the connection of the bolt 310 and improve the structural strength, for example, full welding can be used. In addition, the screw portion of the bolt 310 passes through the through hole 210 and extends upward. When installing the anti-falling ice plate 400, the anti-falling ice plate 400 is placed on the reinforcing beam 200, so that the second end 312 of the bolt 310 passes through the through hole 410, that is, the screw portion passes through the through hole 410, and then cooperates with the bolt 310 through the nut 320, thereby locking the anti-falling ice plate 400. In this way, it can ensure emphasis and facilitate the disassembly and assembly of the anti-falling ice plate 400, reducing on-site construction.

[0064] Optionally, in other embodiments of the present invention, the bolt 310 used in the connecting member 300 may also be considered as a screw rod without a nut portion, as long as the screw rod and the reinforcing beam 200 can be reliably welded.

[0065] In this embodiment, optionally, the screw rod portion of the bolt 310 can be an M16 screw rod. In addition, the bolt 310 is a hot-dip galvanized bolt 310 or a stainless steel bolt 310 to prevent the bolt 310 from rusting.

[0066] Please continue reading Figure 1 In addition, the anti-ice-falling plate 400 roughly adopts a rectangular plate structure. The anti-ice-falling plate 400 can be selected as an anti-slip patterned steel plate, which can ensure the structural strength and can more effectively reduce the damage of ice falling from the fan blades to the box transformer body 11. The through hole 410 opened on the anti-ice-falling plate 400 can be selected as a long strip, so that the screw part on the reinforcing beam 200 can pass through the through hole 410, and sufficient space can also be left for welding. When installing the anti-ice-falling plate 400, a large rust-proof gasket and a spring gasket can also be put on the outside of the screw, so that after the nut 320 is tightened, the locking effect of the nut 320 is better.

[0067] In this embodiment, a lifting ring 420 is welded on the top of the anti-falling ice plate 400, which facilitates the on-site disassembly, lifting, transportation and replacement of the top cover assembly 10.

[0068] See also Figure 7 In addition, in order to further improve the structural strength, the present embodiment further optimizes the arrangement of the reinforcing beams 200. As an example, there are multiple reinforcing beams 200. The multiple reinforcing beams 200 are sequentially arranged on the upper surface of the top cover 100 at intervals along the length direction of the top cover 100, and / or the multiple reinforcing beams 200 are sequentially arranged on the upper surface of the top cover 100 at intervals along the width direction of the top cover 100.

[0069] That is to say, the top cover 100 is generally rectangular in structure as a whole. A plurality of reinforcing beams 200 can be arranged at intervals in sequence along the length direction of the top cover 100 on the upper surface of the top cover 100, or, they can also be arranged at intervals in sequence along the width direction of the top cover 100 on the upper surface of the top cover 100. It is also possible to arrange the reinforcing beams 200 both along the length direction and the width direction of the top cover 100, so as to form a crisscross "field" - shaped reinforcing structure. These three forms of the arrangement of the reinforcing beams 200 can all improve the overall strength of the top - cover assembly 10 and make the anti - falling - ice effect of the top - cover assembly 10 better.

[0070] Please refer to Figure 8 , in some alternative embodiments of the present utility model, the box - type substation 1 further includes a transformer radiator 12, and the anti - falling - ice plate 400 at least partially covers the transformer radiator 12. It should be understood that the anti - falling - ice plate 400 can be enlarged and widened, so that the anti - falling - ice plate 400 protrudes from the edge of the box - type transformer body 11, thereby at least partially covering the transformer radiator 12 to play a role in protecting the transformer radiator 12 from falling ice.

[0071] Please refer to in combination Figures 1 to 8 , when the top - cover assembly 10 provided by the embodiment of the present utility model is installed, the reinforcing beam 200 is pre - connected to the connecting member 300. For example, a bolt 310 passes through the through - hole 210, the bolt 310 is welded to the reinforcing beam 200 in advance, the screw part of the bolt 310 faces upward, and a plurality of reinforcing beams 200 are welded to the upper surface of the top cover 100 according to a preset arrangement method. On the ground, the anti - falling - ice plate 400 is placed on the reinforcing beam 200, so that the screw part of the bolt 310 passes through the perforation 410, and a nut 320 is used to lock it, thereby fastening the anti - falling - ice plate 400 to the reinforcing beam 200. Finally, the top - cover assembly 10 is hoisted as a whole onto the top of the box - type transformer body 11 through the lifting ring 420, thus completing the assembly.

[0072] In summary, for the top - cover assembly 10 and the box - type substation 1 provided by the embodiments of the present utility model, by providing the anti - falling - ice plate 400 and connecting the reinforcing beam 200 between the top cover 100 and the anti - falling - ice plate 400, the structural strength is higher, and it can effectively reduce the damage of falling ice from the fan to the box - type transformer body 11; in addition, due to the use of the connecting member 300 to realize the connection between the reinforcing beam 200 and the anti - falling - ice plate 400, the structure is simpler, easier to disassemble, assemble, maintain and replace, and the on - site construction is reduced.

[0073] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model.
