A kind of afforestation of city band rainwater is collected and the slow automatically irrigation rig of executing
Technical field:
The utility model relates to a kind of rainwater to be collected and irrigation rig, and especially a kind of afforestation of city band rainwater is collected and the slow automatically irrigation rig of executing.
Technical background:
At present, it is a kind of extensive simple method that the collection of rainwater utilizes major part, promptly dig a melt pit, a little water leakage measures are done with cement in inside, and use also is in the rural area basically, collecting rainwater in the city utilizes seldom again, particularly the product with the rainwater automatic-watering flowers and plants of collecting does not also occur, the green land in present city or the flowers and plants that greenbelt is planted are to be watered with professional water trolley or the tap water sprinkling irrigation by city's environmental sanitation department all, be waste water resource like this, the labour who increases municipal personnel again drops into, transport costs etc. are unfavorable for environmental protection, energy-conservation.
Summary of the invention:
The purpose of this utility model is to utilize the rainwater on rainy day effectively to reclaim storage, and then utilizes the rainwater that reclaims to water flowers and plants, and does not need the manual watering.
The technical program is achieved in that at first uses glass fiber reinforced plastic, stainless steel or other material ovalisation or rectangular water tank, the neglecting local use occasion greatly of water tank and deciding, top layer is provided with permeatable filter layer in the upper end of water tank, water filling port, soil humidity sensor, automatically the slow water supply installation, controller etc. executed.Bottom, lower end at water tank is provided with the spill sedimentation basin, and the automatic pollution discharge pump of belt stirrer is installed in sedimentation basin.End at water tank also is provided with gutter water filling connector, and screen pack is housed in the connector.Water filling port both sides in the water tank upper end are connected with removable pipeline formula device for collecting rain water, and screen pack also is housed in the gatherer.When rainy, rainwater flows directly in the water tank by the permeation filtration on water tank upper strata, and the place beyond water tank, then have removable pipeline formula device for collecting rain water that water tank is not related to local rainwater and collect in the water tank, the rainwater that compiles through the gutter in addition flow in the water tank through filter screen by the connector of an end of water tank in addition.Can guarantee the rainwater reserves of water tank through the rain water collecting system of a plurality of settings.Controller on the water tank is then controlled automatically according to the soil moisture situation that soil humidity sensor transmitted and slow executed irrigation rig whether needs are irrigated to flowers and plants, and the automatic pollution discharge pump can start automatically according to the set time of controller the earth in the sedimentation basin is stirred and the discharge water tank.
Description of drawings:
Fig. 1 is an overall structure diagrammatic sketch of the present utility model.
Among the figure: the 1st, water tank, the 2nd, gutter water filling connector, the 3rd, screen pack, the 4th, removable pipeline formula device for collecting rain water (2), the 5th, plastic pipe, the 6th, permeatable filter layer, the 7th, water filling port, the 8th, soil humidity sensor, the 9th, the slow water supply installation of executing, the 10th, controller, the 11st, dredge pump, the 12nd, sedimentation basin.
The specific embodiment:
As Fig. 1: the end at water tank 1 is provided with gutter water filling connector 2, in the inside of gutter water filling connector 2 screen pack 3 is housed; Be provided with permeatable filter layer 6 above water tank 1, water filling port 7 has movably duct type device for collecting rain water 4 respectively in the both sides of water filling port 7, also is mounted with screen pack 3 in device for collecting rain water 4 respectively; Above water tank 1, also be provided with soil humidity sensor 8, the slow water supply installation 9, control device 10 executed; Be provided with sedimentation basin 12 in the bottom of water tank 1, in sedimentation basin 12, be provided with the dredge pump 11 of belt stirrer.
Water tank 1 is made by glass fiber reinforced plastic, stainless steel or other resistant material, and its volume size is decided because of using the place, and water tank 1 can be made multiple shape, but no matter which kind of shape is equipped with spill sedimentation basin 12 in its bottom.
In the removable pipeline formula device for collecting rain water 4 filtering material 3 is housed, is connected with pipeline 5 in 4 bottom, pipeline 5 connects water filling port 6.Removable pipeline formula device for collecting rain water 4 is made up of 2 or a plurality of branch, and its quantity can be decided according to collecting rainwater.
In gutter water filling connector 2 inside filtering material 3 is housed, water injection pipe connector 2 is connected with the urban rainwater drain way.
Control device 10 is made up of soil humidity sensor 8 and computing chip, and slow water supply irrigation rig 9, the automatic pollution discharge pump 11 executed of control.
Be mounted with the own moving dredge pump 11 of belt stirrer in the sedimentation basin 12.
When rainy, the upper end permeable formation of water tank 1 can directly be collected dmp filter in the water tank 1, ground other rainwater filters rainwater at a distance by duct type gatherer movably 4 and connects water filling ports 6 by pipeline 5 and enter in the water tank 1 through filter screen 3, the gutter water filling connector 2 of water tank 1 then is connected with the urban rainwater drain way, flows directly in the water tank 1 after the rainwater in gutter filters by the screen pack on the water filling port 23 to store.
When after the rainy day, when flowers and plants need be watered, at this moment the humidity sensor 8 that is located in the soil transmits signals in the controller 10 according to the humidity of soil, whether controller 10 goes out to supply water according to the transmission calculated signals of humidity sensor 8, controller 10 sends instruction and gives the slow supply-water pump 9 of executing then, slowly executes the water that supply-water pump 9 takes out and is transported to weep pipe pouring flowers and plants again through the slow valve of executing.
Sedimentation basin 12 in the water tank 1 is when having the earth precipitation through after a while, and at this moment, can be dynamically connected certainly stirring suction pumps 11 in the sedimentation basin 12 of setting-up time stir the back to the precipitation earth and discharge water tank 1 outside on the controller 10.
