Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, for the utility model discloses a roof rainwater collecting system, including building 1, building 1's roof upside is equipped with catch basin 2, is equipped with in the catch basin 2 and plants pond 3, plants many support columns of fixedly connected with (not shown in the figure) between the downside in pond 3 and the bottom of pool 2.
Referring to fig. 2 and 3, the gap between the mouth of the planting pond 3 and the mouth of the water collecting pond 2 is an annular overflow gap 4, and a water grate 41 is laid on the overflow gap 4. A plurality of water leakage holes 31 penetrate through the bottom of the planting pond 3, a soil-isolating and water-permeable layer 32 is laid at the bottom of the planting pond 3, the soil-isolating and water-permeable layer 32 is composed of geotextile, and a soil layer 33 for planting green plants is laid on the upper side of the soil-isolating and water-permeable layer 32; one or more absorbent tampons 34 penetrate through each water leakage hole 31, the upper ends of the absorbent tampons 34 penetrate through the soil-separating permeable layer 32 and penetrate to the soil layer 33, the lower ends of the absorbent tampons 34 are located at the bottom of the water collecting pool 2, and the absorbent tampons 34 are used for guiding rainwater in the water collecting pool 2 to the soil layer 33 and are used for the growth of plants.
When the rainfall is small, the rainwater falling into the planting pond 3 downwards sequentially penetrates through the soil separation permeable layer 32 and the water leakage holes 31 and then enters the water collecting pond 2; when the rainfall is large and the water inlet rate of the planting pond 3 is larger than the rainwater infiltration rate of the planting pond 3, a part of rainwater overflows to the water grate 41 and leaks into the water collecting pond 2. Through above-mentioned two kinds of modes, can collect the utilization to the rainwater to a great extent, improve the recovery efficiency of rainwater.
The height of the soil layer 33 is lower than the mouth of the planting pond 3, so as to reduce the outflow of the soil in the soil layer 33 to the water grate 41, namely, the probability of soil loss is reduced.
Referring to fig. 1 and 2, a drainage hole 21 is formed in the wall of the water collecting tank 2, a plug 22 is detachably plugged in the drainage hole 21, and the drainage hole 21 is connected with the bottom of the water collecting tank 2. When the whole stored water in the collecting tank 2 needs to be discharged, the plug 22 can be detached, and particularly after long-term use, a sludge layer is often accumulated in the collecting tank 2, and the sludge is mainly derived from soil lost from the soil layer 33, so that the collecting tank 2 can be cleaned in time to prevent generation of germs. The bottom of the pool 2 is the slope setting, and the bottom of the pool 2 is close to the one end that the bottom of the pool 21 is less than the bottom of the pool 2 and keeps away from the one end of the drain 21 to when draining away the interior retaining of the pool 2, be favorable to draining up retaining and soil. The edge of the roof of the building 1 is provided with a circle of water collecting grooves 5 (see figure 3), and when the water collecting tank 2 is filled with rainwater, the overflowed rainwater flows into the water collecting grooves 5. A water guiding pipe 51 is communicated with the lower side of the water collecting tank 5 and used for guiding out the rainwater in the water collecting tank 5 downwards.
A water storage tank 6 is arranged on the outer side of the bottom floor of the building 1, a partition plate 61 is fixed in the water storage tank 6, the partition plate 61 divides the interior of the water storage tank 6 into a buffer area 62 and a water storage area 63 which are horizontally arranged, an overflow hole 64 is formed in the partition plate 61, and a filter screen 65 is installed on the overflow hole 64; the upper end of the water storage area 63 is closed, the upper end of the buffer area 62 is opened, and the lower end of the water guide pipe 51 is communicated into the buffer area 62; a sand collection basket 66 is positioned at the bottom of the buffer 62. The water drained from the water guide pipe 51 is accumulated in the water storage tank 6 for subsequent use, so that the utilization rate of rainwater is further improved; and because the rainwater drained from the water guiding pipe 51 contains more impurities, the rainwater can be settled in the buffer area 62, the purified water enters the water storage area 63 through the filter screen 65 for subsequent use, and the redundant rainwater overflows from the upper end of the buffer area 62.
A water return pipe 7 penetrates through the water storage area 63, the lower end of the water return pipe 7 penetrates into the water storage area 63, and the lower end of the water return pipe 7 is connected with a water return pump 71; the upper end of the return pipe 7 is communicated into the water collecting tank 2, and the upper end of the return pipe 7 is positioned above the higher end of the bottom of the water collecting tank 2; when the water in the water return pipe 7 is replenished into the water collecting tank 2, the arrangement can have a certain scouring effect on the soil at the bottom of the water collecting tank 2, so that the soil accumulated at the bottom of the water collecting tank 2 is scoured to the water drainage holes 21, and the soil in the water collecting tank 2 is favorably drained. A section in the middle of the water return pipe 7 needs to be higher than the pool opening of the water collecting pool 2, so that water in the water collecting pool 2 is prevented from flowing out through the water return pipe 7 in the water collecting stage of the water collecting pool 2.
The implementation principle of the embodiment is as follows: when the rainfall is small and the water inlet rate of the planting pond 3 is less than the rainwater infiltration rate of the planting pond 3, the rainwater in the planting pond 3 automatically infiltrates into the water collecting pond 2, and after the rain stops, the water in the water collecting pond 2 can be led back into the planting pond 3 by the water absorption cotton sliver 34 to be used for green plant growth. When the rainfall is large and the water inlet rate of the planting pond 3 is larger than the rainwater infiltration rate of the planting pond 3, a part of rainwater overflows to the water grate 41 and leaks into the water collecting pond 2 at the water grate 41. The light is by planting the rainwater is preserved to the mode that soil oozes by oneself in the pond 3, and the water yield that its unit interval internal energy was preserved is very limited, consequently, through the above-mentioned setting, on the basis that soil oozes by oneself, add round water grate 41 to when the rainfall is great, more rainwater of more quick collection can finally improve the recovery efficiency of rainwater.
The water storage tank 6 can collect part of rainwater overflowing from the water collecting tank 2, so that the rainwater recovery efficiency is further improved; meanwhile, the rainwater recovered in the water storage tank 6 can be recycled into the water collecting tank 2, so that the rainwater can be recovered and utilized to a greater extent.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
