Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Present embodiments provide a kind of discarding system that automatically can adapt to SEA LEVEL VARIATION extraction clean rainwater, as shown in Figure 1, this system mainly comprises water tank 1, and water tank 1 is hollow structure, and water tank 1 inside is provided with dividing plate 2, overflow weir 3, filter-type dividing plate 4 successively; Water tank 1 inside is divided into the first abandoned stream space 12, abandoned stream space 11, second, the 3rd abandoned stream space 13 and the 4th abandoned stream space 14 by dividing plate 2, overflow weir 3, filter-type dividing plate 4 successively.
Be provided with the first opening 21 between the inner bottom part of dividing plate 2 and water tank 1, the first abandoned stream space 11 is communicated with the bottom in the second abandoned stream space 12, namely the rainwater in the first abandoned stream space 11 can flow into the second abandoned stream space 12 from the first opening 21.Be provided with the second opening 31 between the inner top of overflow weir 3 and water tank 1, the second abandoned stream space 12 is communicated with the top in the 3rd abandoned stream space 13, namely the rainwater in the second abandoned stream space 12 can flow into the 3rd abandoned stream space 13 from the second opening 31.The rainwater in the 3rd abandoned stream space 13 penetrates into the 4th abandoned stream space 14 by filter-type dividing plate 4.
The top of water tank 1 one side is provided with water inlet pipe 5, and water inlet pipe 5 is communicated with the first abandoned stream space 11, and the bottom in the first abandoned stream space 11 is connected with storm-water drainage pipe 6, and the diameter of storm-water drainage pipe 6 is less than the diameter of water inlet pipe 5; The first abandoned stream space 11 top and near water inlet pipe 5 position on be provided with artificial access hole 7, the top of artificial access hole 7 is provided with cover plate.
The following side in the 4th abandoned stream space 14 is connected with rainwater collection collector 8, and rainwater collection collector 8 one end in the 4th abandoned stream space 14 is connected with rotatable rainwater-collecting standpipe 16, and rainwater-collecting standpipe 16 can around the circumferencial direction unrestricted choice of rainwater collection collector 8; The upper end of rainwater-collecting standpipe 16 is connected with diversion elbow 17, and the end of diversion elbow 17 is provided with filter mantle 19, and it is spherical that filter mantle 19 is preferably semicircle; The top of diversion elbow 17 is fixed with buoyancy aid 18, and buoyancy aid 18 preferably adopts cuboid hollow buoyancy tank.
As Figure 2-Figure 5, along with the rising of the water level in the 4th abandoned stream space 14, buoyancy aid 18 drives rainwater-collecting standpipe 16 to rotate around the circumferencial direction of rainwater collection collector 8, make the clean rainwater space of the end face of the diversion elbow 17 of rainwater-collecting standpipe 16 upper end all the time below the water surface, more than sediment miscellaneous object face, thus ensure diversion elbow 17 all the time automatic sucking to the clean rainwater of zone line.
As one embodiment of the present invention, the inner bottom part of water tank 1 is provided with the slope cushion layer 15 of slope aspect storm-water drainage pipe 6; The position that slope cushion layer 15 contacts with overflow weir 3, filter-type dividing plate 4 is provided with water stream channel.
As one embodiment of the present invention, the top in the 4th abandoned stream space 14 is connected with stormwater overflow pipe 9.
As one embodiment of the present invention, the material of water tank 1, dividing plate 2, overflow weir 3 can be steel concrete, plastic plate, glass fiber reinforced plastic etc.; The material of storm-water drainage pipe 6, water inlet pipe 5, rainwater collection collector 8, rainwater-collecting standpipe 16 can be high density polyethylene, rigid polyvinyl chloride UPVC, stainless steel tube, cast iron pipe etc.
What the present embodiment provided can adapt to the discarding system of SEA LEVEL VARIATION extraction clean rainwater automatically when rainfall, rainwater can enter in the first abandoned stream space 11 by water inlet pipe 5, the foreign material of rain water float, owing to being subject to the obstruction of the dividing plate 2 tackling floating thing, generally not easily enter into the second abandoned stream space 2.While rainwater enters into the first abandoned stream space 11, some rainwater flows out water tank by storm-water drainage pipe 6 and emits, specification due to storm-water drainage pipe 6 is less than the specification of water inlet pipe 5, so rainwater emptying speed is slower than rainwater enter speed in water tank 1, namely the water level in water tank 1 constantly raises.First abandoned stream space 11 is communicated with the bottom in the second abandoned stream space 12, after the second abandoned stream space 12 water level is elevated to the height of overflow weir 3, rainwater enters the 3rd abandoned stream space 13 by the second opening 31, the rainwater in the 3rd abandoned stream space is by entering into the 4th abandoned stream space 14 after the filter-type dividing plate filtration of porous, buoyancy aid 18 swims on the water surface, it is under the upwards buoyancy of rainwater, rotatable rainwater-collecting standpipe 16 can be driven to rotate freely around rainwater collection collector 8 circumferencial direction, swim in light weight sundries that is on the water surface and top layer like this and would not enter rainwater-collecting standpipe 16 through hemispheric mouth of pipe filter mantle 19, the heavier foreign material deposited in the 4th bottom, abandoned stream space 14 also can not enter rainwater-collecting standpipe 16 through the mouth of pipe filter mantle 19 that semicircle is spherical, thus ensure the rainwater of rainwater-collecting standpipe 16 cleaning of automatic sucking zone line all the time.
After rainfall terminates a period of time, the rainwater in water tank 1 all will be spilt out by storm-water drainage pipe 6, and the silt accumulated bottom water tank 1 can be discharged from storm-water drainage pipe 6 along slope cushion layer 15 along with rainwater.
To sum up, the discarding system that automatically can adapt to SEA LEVEL VARIATION extraction clean rainwater provided by the invention can discharge early-stage rainwater, tackles floating foreign material, filters the precipitable foreign material of isolation by automatic shunt, and is automatically collected in Rainwater collection system by later stage clean rainwater.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in the claims in the present invention.
