Detailed Description

The present application is described in further detail below with reference to the attached drawings.

The embodiment of the application discloses an energy-saving roof for a green building. Referring to fig. 1, the energy-conserving roofing of green building includes roof 1, builds eave 11 of locating roof 1 edge and builds planting cofferdam 2 of locating eave 11 inboard, and the side of planting cofferdam 2 is parallel with the side of eave 11 and there is the clearance between planting cofferdam 2 and the eave 11, and eave 11 forms the canal 3 that catchments with planting between the cofferdam 2. Planting soil layer 21 is equipped with in planting cofferdam 2, catchments and installs the spray assembly who is used for spraying planting soil layer 21 between ditch 3 and the planting cofferdam 2.

Referring to fig. 1, the spraying assembly includes a water pump 41 fixedly installed on the top of one side of the planting cofferdam 2, a water conduit 42 and a water spraying pipe 43 communicated with the water pump 41, and a nozzle 45 installed on the water spraying pipe 43, wherein one end of the water conduit 42 away from the water pump 41 is communicated with the water collecting channel 3, and one end of the water spraying pipe 43 away from the water pump 41 extends to the planting soil layer 21.

The ditch 3 that catchments can collect the rainwater when raining, when carrying out the maintenance to planting soil layer 21, can open water pump 41 and spray the vegetation with the water blowout from 45 interior shower nozzles with the ditch 3 that catchments, thereby saved a large amount of daily water through carrying out recycle to the rainwater, the energy saving consumed the festival to planting soil layer 21 and catchment ditch 3 also can play certain thermal-insulated effect, are favorable to saving indoor energy consumption.

In order to spray the planting soil layer 21 more uniformly, one end of the water spraying pipe 43, which is far away from the water pump 41, is communicated with a circular water distribution ring pipe 44, the water distribution ring pipe 44 is laid on the upper surface of the planting soil layer 21, and a plurality of spray heads 45 are uniformly installed on the water distribution ring pipe 44 at intervals, so that the water can be sprayed more uniformly, the spraying effect on the planting soil layer 21 is improved, and the utilization rate of rainwater is further improved.

Referring to fig. 1 and 2, a filtering grid 5 is installed in the water collecting channel 3, convex edges 31 for supporting the filtering grid 5 are respectively built at the tops of two sides of the inner wall of the water collecting channel 3, and two sides of the lower surface of the filtering grid 5 abut against the upper surface of the convex edges 31. The filter grating 5 can block foreign matters, so that the foreign matters are prevented from entering the water collecting channel 3 to block the water conduit 42, and the filter grating 5 can also shield the water collecting channel 3, thereby reducing the evaporation of rainwater in the water collecting channel 3.

Referring to fig. 1, an overflow pipe 32 is horizontally connected to the upper portion of the water collecting channel 3, the overflow pipe 32 penetrates the eave 11 and vertically extends downward, and the connection between the overflow pipe 32 and the water collecting channel 3 is located below the filter grill 5. When the water level in the catchment canal 3 reaches the height of overflow pipe 32, the rainwater can be discharged from overflow pipe 32 to water level in the catchment canal 3 is restricted, prevent that the water level in the catchment canal 3 is too high and flood planting cofferdam 2, avoid causing the influence to the normal growth of planting the interior vegetation of cofferdam 2.

Referring to fig. 2, a plurality of drain holes 22 are uniformly arranged at the bottom of the side wall of the planting cofferdam 2 at intervals, and each drain hole 22 is communicated with the water collecting channel 3. The drain hole 22 can discharge the excessive water in the planting cofferdam 2 after the vegetation is sprayed, and the discharged water flows into the water collecting channel 3 again for reutilization, so that the water loss is reduced, and the water source saving is facilitated. In addition, the level of the drainage hole 22 is higher than that of the overflow pipe 32 to prevent the water level in the catchment channel 3 from being higher than the drainage hole 22, which makes it difficult to drain the water in the planting cofferdam 2.

Referring to fig. 1, in order to reduce the loss of the planting soil layer 21, a non-woven fabric layer 23 is laid between the planting cofferdam 2 and the planting soil layer 21, and the drainage hole 22 is covered by the non-woven fabric layer 23. Non-woven fabrics layer 23 can block soil, avoids planting in soil layer 21's soil flows into the canal 3 along with the rainwater in, and the good water permeability of non-woven fabrics layer 23 blocks very little to the drainage simultaneously, the drainage of being convenient for.

The bottom of the water collecting channel 3 is communicated with a drain pipe 33, and a drain valve 331 is arranged on the drain pipe 33. The drain pipe 33 is convenient for cleaning the sediment deposited in the water collecting channel 3 regularly, and avoids the blockage of the spraying assembly caused by the excessive accumulation of the sediment in the water collecting channel 3.

In order to make silt discharge from blow off pipe 33 more easily, the bottom of collecting channel 3 inner wall sets up along the direction of keeping away from blow off pipe 33 tilt up gradually and forms the inclined plane to play the guide effect to silt in the collecting channel 3, wash silt with water during the clearance, silt flows to blow off pipe 33 more easily, makes things convenient for the clearance of silt.

The implementation principle of the energy-saving roof of the green building in the embodiment of the application is as follows: collect the rainwater through setting up catchment ditch 3 on roof 1, the rainwater of collecting is used for spraying planting soil layer 21 to saved a large amount of daily water, the energy saving, and planting soil layer 21 and catchment ditch 3 also can play certain thermal-insulated effect, are favorable to saving indoor energy consumption. The foreign matters are prevented by arranging the filter grids 5 in the water collecting channel 3, the foreign matters are prevented from entering the water collecting channel 3 to cause the water diversion pipe 42 to be blocked, and meanwhile, the filter grids 5 can also play a role in shielding the water collecting channel 3, so that the evaporation effect of rainwater in the water collecting channel 3 is reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
