Fig. 1 is a sketch map of the present invention.

Embodiment

Below in conjunction with specific embodiment and accompanying drawing, further set forth the present invention.

A kind of irrigation rig; Comprise the closed rainwater cistern 1 that has water inlet 2 and delivery port 3; On the outlet pipe that delivery port 3 connects water flow switch valve 4 is installed, outlet pipe is connected to drip emitters 6 through Water-pumping motor 5, and said cistern 1 is also connecting city planting ductwork water-supply-pipe 7; Water-supply-pipe 7 is connected to the switch 8 in the cistern 1; The bottom is a sand filter blanket 9 in the said cistern 1, and said water flow switch valve 4 links to each other with Humidity Detection controller 10 with Water-pumping motor 5, and said Humidity Detection controller 10 is electrically connected with the accumulator 12 of solar panel 11 with Water-pumping motor 5.

The sand filter blanket 8 of said cistern 1 is a fine sand for the upper strata, under the fine sand separation layer is arranged, and separation layer is cobblestone down; It is big that diameter becomes from top to bottom gradually; The cobblestone bottom has separation net, sand filter blanket 8 bottoms to be equipped with derives " U " type water pipe 13 of bottom filtered water, and water pipe 13 1 ends open wide; Be positioned under the separation net, the other end is connected to the delivery port 3 of cistern 1.Cobblestone also can adopt peastone, rubble or the cobble etc. of particle diameter 1-16mm, the less upper strata that is placed on.Can also some mats of extra laying on fine sand layer as cover layer, in order to avoid the rainwater inflow velocity when fast sand filter blanket be affected.The design of " U " type water pipe 13 makes water outlet easier on the one hand, has also stoped tiny sandstone to pass through on the other hand.Cistern adopts sand filter, and the equipment cost of use is low, and technology is simple, is easy in various outdoor green land operations.

The switch 8 that said city planting ductwork water-supply-pipe 7 is connected in the cistern 1 comprises ball float, soft chain, and ball float is connected with sealed core, and the outer seal of sealed core has the effluent hole, and ball float is fixed on the seal through soft chain, and seal is connected with water-supply-pipe 7.The method is for adopting the simplest float-ball type liquid-level switch, and cost is low, long service life.

Said Humidity Detection controller 10 comprises humidity detecting module, humidity comparison module, control data output module and timing module.Adopt the humidity situation of humidity detecting module testing environment air, surpass like humidity and set humidity, explain that then the water in air branch is enough, need not irrigate; Be lower than setting value like humidity, then need open water flow switch valve 4 and irrigate with Water-pumping motor 5.After once irrigating back a period of time, detect air humidity once more, compare, need to determine whether to irrigate, so reach automatic monitoring, the full-automation control of loop control is irrigated.Controller 10 can also increase the perpetual calendar timing module, and the time of irrigation can be set respectively according to the drying regime of different sunshine times in summer and winter and air, is beneficial to save and effectively utilize the water source.

Said Water-pumping motor 5 is for being applied to the low starting current motor of solar cell; According to the characteristics of solar cell, even to rated voltage, because power is subject to the sunlight conditions influence; Though used accumulator; If but adopt required starting current low, the motor that is easy to start can increase device stability, and is energy-conservation and increase the service life.Can select corresponding motor according to the power output of the solar panel that uses.Motor drives water and flows out, and can connect various drip emitters 6 facilities behind the Water-pumping motor 5, like drip irrigation, and sprinkling irrigation etc., very convenient.

The present invention has made full use of rainwater and municipal water use, combines solar energy that the energy is provided then, and adopts slow and filter filtration, purification rainwater; Both easy operating and enforcement, with low cost again, consumes energy not; Add the humidity controller automatically control irrigation time point that circulates; Whole device has been realized the unmanned irrigation of control automatically, can save a large amount of manpower and materials, but also the conserve water resource and the energy.
