The utility model discloses an outdoor box body with a rainproof structure, the upper end of a box body shell is provided with a convex part or the lower end of the box body shell is provided with a concave part corresponding to the convex part, when the outdoor box body needs to be spliced up and down, the convex part and the concave part can be spliced together to prevent rainwater from seeping into the box body through a splicing seam, and when the outdoor box body is spliced transversely, the convex part and the concave part can be spliced together to prevent rainwater from seeping into the box body. The flow guide grooves can guide infiltrated rainwater into a crack between the two box body supports, then the rainwater flows out, the rainwater is prevented from entering the box body, and the water accumulation risk is also avoided.

The utility model discloses a double-layer side drainage type roof drain device under a mixed roof, which comprises a roof drain main body, a partition plate is arranged at a water inlet of the roof drain main body, the bottom wall of the roof drain main body and the partition plate are obliquely arranged, and the bottom wall of the roof drain main body and the partition plate are horizontally and downwards inclined from the water inlet to a water outlet; the rain hopper is reasonable in design structure, the two channels are formed in the rain hopper body through the partition plate, rainwater on the roof and accumulated water in the heat preservation layer are discharged respectively, meanwhile, the check plate is arranged at the outlet of the lower channel, the check plate is arranged on the lower channel, and therefore the rainwater on the roof and the accumulated water in the heat preservation layer can be prevented from being recharged. And the position is limited through the bottom wall of the rain hopper body and the baffle, so that water in the rain hopper body is prevented from being recharged into the heat preservation layer, and the problems that when the bottom of an existing rain hopper is blocked, rainwater can be deposited in the rain hopper, the rainwater is prone to being recharged along a water passing hole, and the use effect is affected are solved.

The utility model discloses a multi-stage gradient drainage and three-dimensional anti-seepage descending plate area composite waterproof structure, which relates to the technical field of descending plate areas, and comprises a descending plate area main body, an inclined panel is arranged in the descending plate area main body, the bottom surface of the inclined panel is fixedly connected with the inner wall of the descending plate area main body, the two ends of the inclined panel are respectively provided with a downward inclined surface, and the inclined surface is fixedly connected with the inner wall of the descending plate area main body. Drainage grooves are formed in the left end and the right end of each inclined panel, the two drainage grooves correspond to the inclined planes on the two inclined panels, when accumulated water exists on the inclined panels, the accumulated water can flow into the drainage grooves in the two ends along the inclined planes on the inclined panels, when the accumulated water flows into the two drainage grooves, drainage plates in the two drainage grooves can guide the accumulated water to flow into a water outlet, and a water pump is started; the water pump can absorb and drain accumulated water in the plate descending area main body, so that the plate descending area main body has a drainage function, and the problems that the accumulated water enables the ground to be in a humid state for a long time, damage of ground materials is accelerated, and attractiveness and use functions are affected are solved.
