[0038] Each flow guide groove 22 forms a V-shaped groove with the notch facing downward. The connecting plate 41 is a long strip-shaped plate body, and the plate surface is vertically arranged, specifically at the wave bottom of the corrugated plate. The inner inclined plate 21 is designed as a slope structure, and the inner inclined plate 21 is a corrugated plate. Water droplets flow from high to low along the flow guide slope 221 on the corrugated plate to the wave bottom of the corrugated plate, flow along the connecting plate 41 to the water collecting groove 4 at the wave bottom position, and a water guide groove 331 is arranged directly below the first end of the inner inclined plate 21.

[0041] It can be understood that the plate surface of the inner side plate 33 is first vertically downwardly extended, then horizontally bent and extended toward the second end of the inner inclined plate 21, and then vertically bent upward, and the lower part of the entire inner side plate 33 is twice bent to form a U-shaped structure, which constitutes the water guide groove 331. The plate surface of the outer side plate 32 is located outside the inner side plate 33, and is first vertically downwardly extended, then horizontally bent and extended toward the second end of the inner inclined plate 21, then vertically bent upward, and finally horizontally extended toward the second end of the inner inclined plate 21 to form the horizontal plate 323. The lower part of the entire outer side plate 32 is twice bent at right angles to form a U-shaped structure, which constitutes the outer circumferential groove 321, and the outer circumferential groove 321 constitutes the lower part of the groove-shaped structure 31. The horizontal plate 323 can be attached to the groove bottom surface of the water guide groove 331, which is more conducive to the connection of the two.
[0042] In some embodiments, the outer top plate 1 comprises at least one outer inclined plate 11, the number of the outer inclined plates 11 is the same as the number of the inner inclined plates 21, and the side plate 3 is connected to the corresponding outer inclined plate 11. The inclination direction of the outer inclined plate 11 is the same as the inclination direction of the corresponding inner inclined plate 21. Generally, the included angle between the outer inclined plate 11 and the inner inclined plate 21 and the horizontal direction is 5-10°.
[0043] In some embodiments, the number of the inner inclined plates 21 is at least two and is uniformly and spacedly arranged along the horizontal circumference, and a middle partition plate 5 is further connected in the middle of the bottom of the outer top plate 1, and the second end of each inner inclined plate 21 and the corresponding end of each water collecting groove 4 (i.e. the second end of the water collecting groove 4) are connected to the middle partition plate 5.
[0044] The plate surface of the middle partition plate 5 is also vertically arranged. Specifically, the number of the inner inclined plates 21 can be designed as needed. For example, in a specific embodiment, referring to Figure 1, the inner top plate 2 includes two inner inclined plates 21 arranged symmetrically, the number of side plates 3 and water guide grooves 331 is two. The two inner inclined plates 21 form a high-middle-low-low arrangement, the two side plates 3 are also symmetrically distributed, the second end of the two inner inclined plates 21 is connected with the above-mentioned middle partition plate 5; in this specific embodiment, the number of outer inclined plates 11 is also two, the outer inclined plate 11 can adopt a rectangular plate, the inner inclined plate 21 can adopt a rectangular corrugated plate for example, and a side sealing plate is further connected between the two end edges of the outer top plate 1 and the inner top plate 2 along the length direction of the water guide groove 331, which simultaneously seals the two end ports of the side plate 3 along the length direction of the water guide groove 331, so that the hollow cavity 101 in the whole top plate body forms a closed cavity. The two ends of the flow guide groove 22 along the length direction can be sealed by the side wall of the box body 200.
[0045] The material of the whole anti-condensation top cover can be a steel plate, an alloy plate, or other materials.
[0046] Further, the application also provides an electric power equipment box, which comprises a box body 200 with a top opening and the above-mentioned anti-condensation top cover, and the anti-condensation top cover is fixedly arranged at the top opening of the box body 200, and the water falling hole 322 is located outside the box body 200.
[0047] The electric power equipment box has the above-mentioned anti-condensation top cover, and the box body 200 can be used to install components and devices. By designing the inclined surface and the flow guide groove 22, and using the water collecting groove 4 and the water guide groove 331, it is beneficial for the condensation generated on the outer surface of the bottom of the top cover body 100 to flow along the surface tension of water droplets to the water collecting groove 4 and further to the water guide groove 331 for drainage outside the box, which can reduce the electric power failure caused by condensation and create better economic benefits.
[0048] In an optional embodiment, referring to Figure 2 When the number of inner inclined surfaces is two, the box body 200 is a rectangular body structure, and the side wall of the box body 200 near the water guide groove 331 can be horizontally bent and extended into the box body 200 to form a support plate 201, which abuts against the horizontal plate 323 below.
[0049] In summary, the anti-condensation top cover and the electric power equipment box in the embodiment can be applied to box-type substations, ring network boxes, JP cabinets and other electric power equipment prone to condensation. By forming a certain slope with the inner inclined plate 21 and using a corrugated plate for the inner inclined plate 21, the water collecting groove 4 is arranged at the bottom of the corrugated plate along the flow direction of water droplets, and the water guide groove 331 is arranged at the two side edges of the whole top cover body 100 when the number of inner inclined plates 21 is two. When the humidity in the electric power equipment box is high, water vapor condenses into condensation on the anti-condensation top cover. Referring to Figures 1 to 3The arrow 300 in the figure indicates the flow direction of the condensation water drops, when the condensation reaches a certain degree, it will gather to the water collecting groove 4 along the small inclined surface of the corrugated plate, and then flow to the water guide groove 331 on both sides of the two inner inclined plates 21 from high to low, when the condensation water drops in the water guide groove 331 gather to a certain degree, it will drip along the water leakage hole 332 to the groove structure 31 outside the box body 200, and then be discharged outside the power equipment box through the water falling hole 322, so that the failure caused by the condensation dropping on the components can be avoided.
