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 high-rise building rainwater recovery system, including building body 1, the edge at building body 1 top sets up along the direction of keeping away from building body 1 tilt up gradually and forms eaves 11 that catchments, and the lateral wall intercommunication of eaves 11 that catchments has a collector pipe 12. The water collecting pipe 12 extends downwards vertically along the side wall of the building body 1 and is communicated with a rectangular parallelepiped structure and a sand sediment box 2 with a cavity inside, the center of the bottom of the sand sediment box 2 is sunken downwards to form an inclined plane, the bottom of the sand sediment box 2 is communicated with a drain pipe 21 along the vertical direction, and the drain pipe 21 is provided with a drain valve 211.

The upper portion intercommunication of sand sediment box 2 has a connecting pipe 3, and the one end intercommunication that sand sediment box 2 was kept away from to connecting pipe 3 has a water storage tank 4, and the highest level of water storage tank 4 is less than the highest level of sand sediment box 2, and connecting pipe 3 is followed the direction that is close to water storage tank 4 and is leaned on gradually then vertical buckling downwards and communicateing in the top of water storage tank 4. The bottom of the water storage tank 4 is also communicated with a water pump 41, the water pump 41 is communicated with a cleaning pipe 5, and one end of the cleaning pipe 5, which is far away from the water pump 41, is communicated with the top of the sand box 2.

When raining, the rainwater can receive the eaves 11 that catchments after falling to the roof and stop, and eaves 11 that catchments inclines inclined slightly along the direction that is close to collector pipe 12 and sets up, makes the rainwater flow to collector pipe 12 in more easily, and the rainwater flows to in the sand sediment box 2 through collector pipe 12. After storing full rainwater in sand box 2, the rainwater can be in connecting pipe 3 flows into water storage tank 4, and water storage tank 4 collects the rainwater, can utilize the rainwater once more, saves the water resource, and drainage system's pressure when also can alleviate rain simultaneously reduces the possibility of flood.

Because one section slope that connecting pipe 3 is close to sand setting tank 2 upwards sets up, can flow to the in-process of water storage tank 4 at the rainwater and play the effect of subsiding to remaining silt in the rainwater, silt can receive the action of gravity to subside to sand setting tank 2 when flowing through connecting pipe 3 in, has reduced the possibility that silt got into water storage tank 4. Crisscross welding has polylith separation blade 31 on the inner wall of connecting pipe 3, and separation blade 31 can block the silt of rainwater, has further improved the effect of subsiding of silt when connecting pipe 3 flows through.

The sand sediment box 2 is used for precipitating rainwater, so that silt carried in the rainwater is precipitated to the bottom of the sand sediment box 2, and the silt is prevented from entering the water storage tank 4 along with the rainwater. The scavenge pipe 5 is used for wasing the sand setting case 2, opens water pump 41 and opens blowoff valve 211 during washing, and the water in the water storage tank 4 washs sand setting case 2 through the scavenge pipe 5 blowout, washes out silt through blow off pipe 21, prevents that silt from accumulating in sand setting case 2 for a long time and causing the jam.

Referring to fig. 2 and 3, the cleaning pipe 5 extends into the interior of the sandbox 2 to the upper part of the sandbox 2 and is communicated with a circular ring pipe 51, the lower surface of the ring pipe 51 is communicated with four water spraying pipes 52 at uniform intervals, a nozzle 53 is installed at the pipe orifice of each water spraying pipe 52, and the directions of the four nozzles 53 are respectively aligned with four top corners of the bottom of the sandbox 2. When cleaning the sand box 2, the ring pipe 51 and the water spray pipe 52 make the water in the cleaning pipe 5 uniformly sprayed out, improving the cleaning effect of the sand box 2, and the nozzle 53 makes the sprayed water have faster flow velocity and impact force, further improving the cleaning effect of the sand box 2.

The nozzle 53 is aimed at the base angle of the sand sediment box 2, can prevent that the edges and corners of the bottom of the sand sediment box 2 from remaining silt, and the bottom of the sand sediment box 2 is set as an inclined plane which can play a guiding role for silt when cleaning, so that silt flows out of the sewage discharge pipe 21 more easily, and is convenient to clean and prevents partial silt from depositing in the sand sediment box 2.

The lower part of the sand sediment box 2 is communicated with a water pipe 22, a water delivery valve 221 is arranged on the water pipe 22, and one end of the water pipe 22 far away from the sand sediment box 2 extends along the horizontal direction and is communicated with the upper part of the water storage tank 4. After the rain stops, the sand sediment box 2 is firstly kept stand, after the sediment in the rainwater is deposited at the bottom of the sand sediment box 2, the water delivery valve 221 is opened, and due to the liquid level difference between the sand sediment box 2 and the water storage tank 4, most of the water in the sand sediment box 2 flows into the water storage tank 4 through the water delivery pipe 22, so that the recovery amount of the rainwater is increased, and the water resource is saved. One end of the water pipe 22 close to the sand box 2 is provided with a filter screen 222, and the filter screen 222 can further filter rainwater to prevent foreign matters from entering the water storage tank 4 through the water pipe 22.

The bottom of the water storage tank 4 is communicated with a drainage pipe 42 along the vertical direction, a drainage valve 421 is installed on the drainage pipe 42, when the water storage tank 4 is fully stored, the drainage valve 421 is opened to drain water in the water storage tank 4, rainwater is prevented from backflushing into the sand sediment box 2 or the water collecting pipe 12, and meanwhile, the drainage pipe 42 is arranged to facilitate cleaning of the inside of the water storage tank 4 and cleaning of silt entering the water storage tank 4.

The implementation principle of the embodiment is as follows: collect the rainwater through setting up water storage tank 4, utilize the rainwater of collecting once more, can save a large amount of water resources, drainage system's pressure when also can alleviating rain simultaneously reduces the possibility of flood. Through setting up sand setting tank 2 and deposiing the rainwater, make the bottom of sand setting tank 2 of sediment that carries in the rainwater, prevent that silt from getting into in water storage tank 4 along with the rainwater. Be used for wasing sand setting box 2 through setting up scavenge pipe 5, avoid silt to pile up in sand setting box 2 for a long time and lead to blockking up.

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.
