Fill out.Easy for construction, short time limit.With support, water storage, the effect of purification.The water in rainwater collection pool 12 can be upper strata simultaneously
The biologies such as green plant provide moisture.
Embodiment 1
Level monitor is combined using water-level probe 14 and water level display alarm instrument 15, and water-level probe 14 experiences hydraulic pressure
Change, then transfer data to water level display alarm instrument 15, making one on the ground just can be to the rain of rainwater collection pool 12
Water is understood, the SEA LEVEL VARIATION in the cistern that display rainwater-collecting module 11 forms, when water level is less than certain warning value
When can send alarm, remind the timely moisturizing of municipal administration personnel.
The rainwater of rainwater collection pool is understood, is easy to control, and accuracy is higher, is easy to accurately control, but need
There is provided electricity could use, and install inconvenience.
Embodiment 2
Level monitor uses column structure 17, vertically inside rainwater collection pool 12, and passes through biological retention layer
2, there is the liquid for observation inside Level monitor.Column structure 17 is placed in inside rainwater collection pool 12, water is from column
The bottom up jack-up of structure 17, and the upper surface of concave herbaceous field 1 is extended to, by the liquid level of fluid column, judge rainwater
The change of water level in collecting pit 12, the Level monitor of column structure 17 is easy for installation, and is easy to observe, it is not necessary to powers,
But service life is short.
Rainwater-collecting module is installed on underground, can be arranged at the underground in the places such as city, cell, factory, landscape on demand, no
Floor space is taken, and rainwater collection pool 12 is combined into a pond by several rainwater-collecting modules 11, the shape in pond is not
Determine, any combination, do not limited by place with terrain generalization, because the method mutually spliced using module, without big machinery,
Easy for construction, short time limit.With support, water storage, the effect of purification.The rainwater of collection can be for a long time the green plants on ground
Moisture required for growth is provided, effectively utilizes nature rainwater, reduces the artificial water for taking running water irrigating plant, it is same with this
When save be detained rainwater, reduce surface runoff, be advantageous to the construction in sponge city, preserve the ecological environment, it is good in economic efficiency
Advantage.Two kinds of Level monitors are chosen as needed, the rainwater of rainwater collection pool 12 can be understood, are easy to control,
And accuracy is high, it is easy to use, PP materials are regenerated environment protecting material, and green, buried underground does not destroy whole ecological environment,
Safeguard simply, and recyclable recycling.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
The limitation present invention, all any modification, equivalent and improvement made within the spirit and principles of the invention etc., all should be included
