Utility model content
The purpose of this utility model is that solve above-mentioned the deficiencies in the prior art, there is provided a kind of self-cleaning based on water-jet
Storm detention tank.
The utility model is achieved through the following technical solutions：
A kind of self-cleaning storm detention tank based on water-jet, storage pond is by 1 ~ 4 arranged side by side group of self-cleaning unit transverse
Into each self-cleaning unit bottom center sets longitudinal spoil disposal ditch with certain head fall, is upper at left and right sides of spoil disposal ditch
Slope is risen, two neighboring self-cleaning unit is connected at the top of acclivity；Spoil disposal ditch bottom center is according to pond length edge of regulating and storing
Longitudinally disposed 2~10 360 degree of Plane Rotation shower nozzles, the range of 360 degree of Plane Rotation shower nozzles is acclivity top and shower nozzle
1.5 times of vertical range；Spoil disposal ditch slope aspect end sets out pump sump.Storage pond bottom and surrounding do antiseepage resistance to compression processing.
Preferably, each self-cleaning unit bottom only sets a spoil disposal ditch, spoil disposal ditch width 1m, length and self-cleaning list
Member or the equidirectional length in storage pond bottom are consistent；The distance of the two neighboring 360 degree of Plane Rotation shower nozzles in spoil disposal ditch bottom is shower nozzle
The distance of 1.4 times of range, bottom two 360 degree of Plane Rotation shower nozzles of head and the tail and pool wall is 0.7 times of sprinkler pattern range.
Preferably, the head fall of the spoil disposal ditch is 3 ‰.
Preferably, it is described go out pump sump in set submersible sewage pump.
Preferably, 360 degree of Plane Rotation head of the nozzle are fixed in spoil disposal ditch, the spray of 360 degree of Plane Rotation shower nozzles
Height is penetrated with being flushed at the top of acclivity.
Preferably, the range of 360 degree of Plane Rotation shower nozzles is 15~20m, and Plane Rotation speed is 1~2r/min,
Injection flow is 8~12 L/S, and nozzle diameter is 3~6cm.
Preferably, the gradient of the spoil disposal ditch both sides acclivity is 3~5%.
The beneficial effects of the utility model are：
The utility model has carried out self-cleaning innovation on the basis of traditional storm detention tank, reduces self-cleaning cost
And operation energy consumption, effectively increase storage pond efficiency and operation stability.Meanwhile self-cleaning shower nozzle water spray can use rainwater purification
Water outlet or sewage treatment plant tail water afterwards, realize reclaimed wastewater reuse.

Embodiment
To be best understood from the utility model, the utility model is further described with reference to embodiment and accompanying drawing, with
Lower embodiment is only that the utility model is illustrated rather than it is limited.
System architecture：
As Figure 1-4, a kind of self-cleaning storm detention tank based on water-jet, storage pond is by 3 self-cleaning units 1
Laterally composition side by side, it is 3 ‰ that each bottom center of self-cleaning unit 1, which sets a head fall, width 1m, length with from clear
Wash the consistent spoil disposal ditch 2 of 1 equidirectional length of unit, the left and right sides of spoil disposal ditch 2 is the acclivity 3 of the gradient 4%, it is two neighboring from
Cleaning unit 1 is connected at the top of acclivity 3, and the distance between two tops of acclivities 3 are 20 meters；The bottom of spoil disposal ditch 2
Longitudinally disposed 5 360 degree of Plane Rotation shower nozzles, 4, the 360 degree of bottoms of Plane Rotation shower nozzle 4 in center are each attached in spoil disposal ditch 2,
And jetting height flushes with the top of acclivity 3, the range of 360 degree of Plane Rotation shower nozzles 4 is 15 meters, bottom head and the tail two
The distance of 360 degree of Plane Rotation shower nozzles 4 and pool wall is 10.5 meters, and the distance of two neighboring 360 degree of Plane Rotation shower nozzles 4 is 21
Rice；Spoil disposal ditch 2 sets out pump sump 5 along gradient end, goes out and submersible sewage pump is set in pump sump 5.
System principle：
A kind of self-cleaning storm detention tank based on water-jet, comprises the following steps：
