Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
A kind of unpowered rain water drainage pollution cutting device, comprise an abandoned stream chamber 8, described abandoned stream chamber 8 is provided with horizontal water inflow pipe 1 near the side at top, rainwater is transported to bucket-shaped coarse filter device 3 downwards by centrifugal device 2 by one end that described horizontal water inflow pipe 1 is positioned at abandoned stream chamber 8, the inwall of described abandoned stream chamber 8 is close at the edge large suitable for reading of described bucket-shaped coarse filter device 3, the little end opening of described bucket-shaped coarse filter device 3 is provided with tube connector 4, described tube connector 4 is provided with horizontal outlet pipe 7, described horizontal outlet pipe 7 is provided with thin filter 6, the below of described tube connector 4 is provided with ball float 5-2 device 5, when the water yield acquires a certain degree, the ball float 5-2 of ball float 5-2 device 5 blocks the bottom of described tube connector 4, between the sidewall of described ball float 5-2 device 5 and described abandoned stream chamber 8, there is gap, the bottom of the described abandoned stream chamber 8 below described ball float 5-2 device 5 is provided with water flow speed reduction device, the aperture of described water flow speed reduction device is greater than the aperture of bucket-shaped coarse filter device 3.
Further, described ball float 5-2 device 5 comprises ball float 5-2 and two piece of spring stop 5-1, the side of described two spring stop 5-1 is equipped with spring, two spring stop 5-1 do not arrange the downward-sloping setting in side of spring also near clamping described ball float 5-2, described ball float 5-2 is positioned at immediately below described tube connector 4, one end that described two spring stop 5-1 are provided with spring is positioned at described abandoned stream chamber 8 diametrically, and the bottom of two springs is all fixed on the sidewall of described abandoned stream chamber 8.With the increase of rate of water added, the spring under spring stop 5-1 can press down by the gravity of rainwater, and the other end of spring stop 5-1 will tilt, and then drives ball float 5-2 upwards to block the lower end of tube connector 4.Accelerate the floating of ball float 5-2, have positioning action to ball float 5-2 simultaneously.
Further, described tube connector 4 end and described spring stop 5-1 high-end between be provided with up-small and down-big horn mouth, described bell-mouthed lower bore is slightly less than the length of the high-end line of described two latch plates.The water that bucket-shaped filter covering of the fan leaks down by such convenience and dirt slip down to the spring side of spring stop 5-1 along horn mouth, accelerate spring stress by ball float 5-2 jack-up, accelerate the collection of rainwater.
Further, the bottom bore of described tube connector 4 is slightly larger than the bore of the tube connector 4 below outlet pipe 7.Prevent ball float 5-2 transition from floating, block outlet pipe 7.
Further, described centrifugal device 2 is helix tube.Structure is simple, and cost is low, simultaneously without the need to power.
Further, described bucket-shaped coarse filter device 3 is the funnel that covering of the fan is provided with spiral line type notch.Structure is simple, and cost is low, increases the centrifugal force of rainwater simultaneously, and make the amount of rainfall entering tube connector 4 more, the rainwater namely collected is more, and abandoned stream is less, also can increase the later stage (ball float 5-2 reset after) to wash away dynamics to tube connector 4 tube wall simultaneously.
Further, described water flow speed reduction device is large aperture filter screen.Structure is simple, and cost is low, saves space.
Further, described thin filter 6 is the filter screen of aperture 1-5mm.Meet the requirement of different degree of filtration, improve compliance.
The course of work of this example:
After rainfall starts, the rainwater confluxed in roofing or road surface enters hydraulic centrifugal device 2 by water inlet pipe 1, and make rainwater flow into bucket-shaped coarse filter device 3 with eddy currents, the bulk impurity in rainwater rests on above bucket-shaped coarse filter device 3, or bottom of dropping.Rainwater with suspension and fine impurities flows out, and enters tube connector 4.Abandoned stream chamber 8 can set certain rainfall, discharges bottom abandoned stream chamber 8.Along with rainfall constantly increases, beat the pressure increase on the spring stop 5-1 of the ball float 5-2 device 5 bottom abandoned stream chamber 8, the ball float 5-2 be stuck in the middle of two spring stop 5-1 floats, and blocks the outlet of tube connector 4.Along with tube connector 4 liquid level rises, rainwater is the thin filter 6 of 1-5mm through aperture, and after further fine filtering, comparatively clean rainwater enters rain water collecting system from the outlet pipe 7 at middle part.Rainwater enters thin filter 6, carries out secondary filter, some suspensions and fine impurities is filtered, clean rainwater is entered rain water collecting system by delivery port.
After rainfall terminates, the pressure of the spring stop 5-1 spring terminal of ball float 5-2 device 5 constantly reduces, spring stop 5-1 automatically resets under the effect of spring force, and then drive ball float 5-2 to automatically reset, filter the dirt produced also to flow out with rainwater remaining in tube connector 4, abandoned stream room empties automatically, and this device resets, for rainfall is ready next time.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
