[0013] According to the description of the utility model, compared with the prior art, the utility model has the following beneficial effects:

[0014] In the first technical solution, the waterproof and dustproof structure is provided with the waterproof grid part and the dustproof cotton part which is located behind the waterproof grid part, so that the dustproof cotton part can be used for dustproofing in addition to the waterproof grid part.

[0015] The waterproof grid part comprises a plurality of blades arranged in the up-down direction and extending in the left-right direction, the upper surface of the blade is inclined forward, so that a gap can be formed between the blades for airflow to pass through while the water flow from the upper to the lower direction, such as rain, can be preferably prevented. The upper and lower ends of the blade are respectively provided with a first extension and a second extension extending in the up-down direction, the first extension of one of the two adjacent blades intersects with the second extension of the other blade in the up-down direction, so that when the water flow hits the waterproof grid part from the front-rear direction, it cannot directly penetrate the waterproof grid part, and the water flow hitting the upper surface of the blade needs to first pass over the first extension of the blade before it can pass over the waterproof grid part. The extension directions of the first extension and the second extension are parallel to each other and only intersect in the up-down direction, and because the upper surface of the blade is inclined forward, there is a large space between the first extension of the blade and the second extension of the adjacent blade, so that the wind resistance is low.

Therefore, even if the water flow hits the dustproof cotton part after passing through the waterproof grid part, it will be blocked by the dustproof cotton part and then flow into the drainage groove and then be drained through the first drainage hole under the action of gravity. Therefore, compared with the existing technology in which the adjacent "s" blades are almost buckled, the waterproof and dustproof structure provided by the technical solution can have better waterproof and dustproof performance with lower wind resistance, and can also have lower cost compared with the use of "s" type blades.

[0017] In addition, in the front-rear direction, the opening of the first drainage groove extends to the rear of the dustproof cotton part, so as to receive water that penetrates the dustproof cotton part. Therefore, when the dustproof cotton part cannot completely block the water flow, the potential energy of the water flow that penetrates the dustproof cotton part will be greatly reduced, so as to fall into the first drainage groove and then be drained through the first drainage hole.

[0018] In the second technical solution, a second drainage groove is arranged below the waterproof grid part, the second drainage groove is suitable for receiving water flowing down from the waterproof grid part and is provided with a second drainage hole for draining water flow therein, so that the water flowing down from the waterproof grid part can be specially drained to avoid flowing to other places.

[0032] As shown in Figure 1 The utility model discloses a cabinet door plate.

[0033] As shown in Figure 2 And 3 The cabinet door plate in the embodiment is provided with a waterproof and dustproof structure, which is provided with a waterproof grid part 1, a dustproof cotton part 2, a first drainage groove 3 and a second drainage groove 9.

[0034] The waterproof grid part 1 comprises a plurality of blades 4 arranged in the up-down direction and extending in the left-right direction, the upper surface 5 of the blade 4 is inclined to the front and downward, and the upper and lower ends of the blade 4 are also respectively provided with a first extension 6 and a second extension 7 extending in the up-down direction, the first extension 6 of one of the two adjacent blades 4 intersects with the second extension 7 of the other in the up-down direction, that is, in the projection in the front-back direction (on the projection plane perpendicular to the front-back direction), the first extension 6 of one of the two adjacent blades 4 at least partially overlaps with the second extension 7 of the other.

[0035] The dustproof cotton part 2 is located behind the waterproof grid part 1 and adjacent to the waterproof grid part 1. In the embodiment, the dustproof cotton part 2 is plate-shaped, the material used is polyurethane, the pore size is 25PPI, and the thickness is 10mm.

[0036] The first drainage groove 3 is located below the dustproof cotton part 2, and the opening thereof faces upward so as to be suitable for receiving water flowing down from the dustproof cotton part 2. The first drainage groove 3 is also provided with a first drainage hole 8 for discharging water flow therein. The number of the first drainage hole 8 can be set according to the actual situation, and in the embodiment, the number is four. In the embodiment, in the front-back direction, the opening of the first drainage groove 3 extends to the rear of the dustproof cotton part 2, so as to be suitable for receiving water penetrating the dustproof cotton part 2.

[0037] The second drainage groove 9 is located below the waterproof grid part 1, which is adapted to receive the water flowing down from the waterproof grid part 1 and is provided with a second drainage hole 10 for draining the water flow therein. The number of the second drainage hole 10 can also be set according to the actual situation, and the number in the embodiment is four.

[0038] The working principle of the waterproof and dustproof structure in the embodiment is as follows:

[0039] When the water flow hits the waterproof and dustproof structure from the front to the back, since the first extension part 6 and the second extension part 7 intersect in the up-down direction, the water flow cannot directly penetrate the waterproof grid part 1. Since the upper surface 5 of the blade 4 is inclined forward, the water flow hitting the upper surface of the blade 4 will be scattered, only the water flow over the first extension part 6 can penetrate the waterproof grid part 1, and the rest of the water flow will be collected into the second drainage groove 9 and then discharged from the second drainage hole 10. For the water flow that penetrates the waterproof grid part 1, it will hit the dustproof cotton part 2, if it cannot penetrate the dustproof cotton part 2, it will flow down along the dustproof cotton part 2 and then be collected into the first drainage groove 3 and then discharged by the first drainage hole 8. For the water flow that penetrates the dustproof cotton part 2, since it has been buffered by the dustproof cotton part 2, the potential energy of the water flow is greatly reduced, and the opening of the first drainage groove 3 extends to the back of the dustproof cotton part 2, so it will also be collected into the first drainage groove 3 and then discharged. The dustproof cotton part 2 itself can also play a dustproof role, thereby achieving the purpose of waterproof and dustproof. It has been tested that the waterproof and dustproof structure provided in the embodiment can achieve IP54.

[0040] It should be noted that in other embodiments, the selection of the material and thickness of the dustproof cotton part 2 can be determined according to the structure of the waterproof grid part 1 used, as long as it is configured to reduce the potential energy of the water flow after penetrating it to flow out of the first drainage groove 3 through the opening of the first drainage groove 3.

[0041] In the embodiment, the waterproof and dustproof structure is provided with a waterproof grid part 1 and a dustproof cotton part 2 located behind the waterproof grid part 1, so that in addition to waterproofing by the waterproof grid part 1, dustproofing can also be achieved by the dustproof cotton part 2. The waterproof grid part 1 includes a plurality of blades 4 arranged in the up-down direction and extending in the left-right direction, the upper surface 5 of the blade 4 is inclined forward, so that a gap can be formed between the blades 4 for airflow to pass through while the water flow from the upper to the lower direction, such as rain, can be better prevented. The upper and lower ends of the blade 4 are respectively provided with a first extension part 6 and a second extension part 7 extending in the up-down direction, the first extension part 6 of one of the two adjacent blades 4 intersects with the second extension part 7 of the other in the up-down direction, so that when the water flow hits the waterproof grid part 1 from the front-rear direction, it cannot directly penetrate the waterproof grid part 1, and the water flow hitting the upper surface of the blade 4 needs to first pass over the first extension part 6 of the blade 4 before it can pass over the waterproof grid part 1, and the extension directions of the first extension part 6 and the second extension part 7 are parallel to each other and only intersect in the up-down direction, and since the upper surface 5 of the blade 4 is inclined forward, there is a large space between the first extension part 6 of the blade 4 and the second extension part 7 of the adjacent blade 4, resulting in lower wind resistance. The waterproof and dustproof structure is also provided with a drainage groove located below the dustproof cotton part 2, the opening of the drainage groove faces upward and is suitable for receiving water flowing down from the dustproof cotton part 2, and it is also provided with a first drainage hole 8 for draining the water flow therein, so that even if the water flow passes over the waterproof grid part 1 and hits the dustproof cotton part 2, it will be blocked by the dustproof cotton part 2 and then flow into the drainage groove and then be discharged through the first drainage hole 8. Therefore, compared to the existing technology in which the adjacent "s" blades 4 are almost locked, the waterproof and dustproof structure provided by the technical solution can have better waterproof and dustproof performance with lower wind resistance, and can also have lower cost compared to using "s" shaped blades 4.

[0042] In the embodiment, by providing a second drainage groove 9 below the waterproof grid part 1, the second drainage groove 9 is suitable for receiving water flowing down from the waterproof grid part 1 and is provided with a second drainage hole 10 for draining the water flow therein, so that the water flowing down from the waterproof grid part 1 can be specially drained to avoid flowing to other places.

[0043] In the embodiment, in the front-rear direction, the opening of the first drainage groove 3 extends to the rear of the dustproof cotton part 2, so as to receive water that penetrates the dustproof cotton part 2, so that when the dustproof cotton part 2 cannot completely block the water flow, the potential energy of the water flow that penetrates the dustproof cotton part 2 will also be greatly reduced, so as to fall into the first drainage groove 3 and then be discharged through the first drainage hole 8.

[0044] The embodiment also provides an outdoor energy storage electrical equipment which also adopts the cabinet door plate and the waterproof and dustproof structure in the embodiment.

[0045] The description of the above specification and the embodiment is used to explain the protection scope of the utility model, but does not constitute the limitation to the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiment, the modification, equivalent replacement or other improvement of the utility model embodiment or one part of technical features can be obtained by the ordinary skill in the art in combination with the common knowledge, the ordinary skill in the art and / or the prior art through logical analysis, reasoning or limited test, and should be included in the protection scope of the utility model.
