Summary of the invention
The objective of the invention is to propose a kind of energy saves energy and water resource, and automatic irrigation system easy to use.
The automatic irrigation system that the present invention proposes is a kind of irrigation system that solar energy and pressurized tank are combined.Promptly, realize effectively irrigating in conjunction with automation control by 2 accumulation of energys.
So-called 2 accumulation of energys are: 1, and be electric energy with transform light energy, electric energy has been saved the power supply of the system of being used as by accumulator.2, utilize the air compressibility, with air compressor pressurized tank is carried out pneumatic compression, irrigate required pressure thereby reach.
Concrete structure of the present invention as shown in Figure 1, this automatic irrigation system is connected to form through connecting line by photovoltaic cell 1, charge controller 2, accumulator 3, air compressor 4, pressurized tank 5, tank 6, irrigation conduit 7 and automatic controller 8; Wherein, photovoltaic cell 1, charge controller 2, accumulator 3 connect successively; Air compressor 4 is connected by pipeline with the air inlet on pressurized tank 5 tops, and pipeline is provided with intake valve 9, and tank 6 is connected by pipeline with the water inlet at pressurized tank 5 middle parts, and pipeline is provided with water intaking valve 10; The bottom delivery port of pressurized tank 5 is connected with irrigation conduit 7 by tube connector, and tube connector is provided with outlet valve 13; Automatic controller 8 is connected with air compressor 4, implements air compressor 4 is controlled; Automatic controller 8 provides power supply by the photovoltaic cell system; Pressurized tank 5 tops are provided with manometer 11, and the tube connector between pressurized tank 5 and the manometer 11 is provided with arm, and arm is provided with relief valve 12; The bottom of pressurized tank 5 is provided with down water gauge 17, is used for the next water level of gaging pressure jar 5, and the top of pressurized tank 5 is provided with water gauge 18, is used for the top water level of gaging pressure jar 5.
In addition, system also is provided with medicine storing pot 14, and medicine storing pot 14 is connected by the middle part of pipeline with pressurized tank 5, and pipeline is provided with soup control valve 15.
Among the present invention, irrigation conduit 7 can extend to the place that need irrigate, and for example green area irrigation, crop irrigation, flowers irrigation etc. can be provided with different nozzles on the irrigation conduit 7, implement drip irrigation and spray irrigation, atomizing humidifying performance etc.
Operation principle of the present invention is as follows: when raining storing as source of irrigation water after the rainwater collection, thereby can the energy-saving tap water resource; Utilize the solar-energy photo-voltaic cell generating, and get up, as the working power of system by accumulators store; Utilize air compressor to make the glassware for drinking water in the pressurized tank that certain pressure be arranged, for water flows out, irrigation provides kinetic energy; Water through pressurization is implemented to irrigate by pipeline.
It is as follows to utilize the present invention to carry out the process of concrete operations: rainwater is through collecting, being stored in the tank 6; Photovoltaic cell 1 utilizes solar electrical energy generation, and by photoelectric controller 2 with power storage in accumulator 3, the photovoltaic cell system provides power supply for automatic controller 8.4 work of automatic controller 8 control air compressors; During system works, open water intaking valve 10 and relief valve 12, the water in the tank 6 is entered in the pressurized tank 5, arrive when setting the high water level place, close water intaking valve 10 and relief valve 12, stop into water.At this moment, other valves also are in closed condition, and pressurized tank 5 becomes closed container.Open air compressor 4, open intake valve 9, fill compressed air in pressurized tank 5, to setting pressure, air compressor 4 quits work.At this moment, have certain pressure in the pressurized tank 5, open outlet valve 13, water is implemented to irrigate through irrigation conduit 7.When water level in the pressurized tank 5 was low to moderate the setting low water level, outlet valve 13 was closed, and system stops water outlet.Open relief valve 12 and water intaking valve 10, system intakes again, pressurization then, and water outlet is irrigated again, so, moves in circles.
System is provided with dosing and irritates 14, can add agricultural chemicals or nutrition as required, enters pressurized tank 5 by pipeline and control valve 15, after water mixes, exports in the lump when irrigating.
The present invention is widely used, and except that carrying out traditional crop irrigation, also can carry out irrigations such as place greening, roof greening, warm grid plant, is particularly suitable for the place use that does not have civil power and manually be difficult to realize irrigate at some.And system can accurately control the water yield, irrigation time, and can add nutriment, agricultural chemicals etc. automatically, uses very convenient.
The invention is further illustrated by the following examples.
500 watts of the power of photovoltaic cell 1 are equipped with corresponding charge controller 2 and accumulator 3,200 watts of the power of air compressor 4.Pressurized tank 5 be circular, make of metal material, volume is 30 cubic metres, tank 6 is a bigger pond, and volume is about 200 cubic metres, can be according to place size specific design, adopt reinforced concrete structure, medicine storing pot 14 volumes are 1 cubic metre, adopt stainless steel material to make.
Irrigation conduit 7 is provided with 1-3 road branch, and every diameter is 1.5cm, adopts engineering plastics and elastomeric material to make, and some nozzles or drip nozzle is set on the pipeline waits until, pipe branch quantity, length, nozzle etc. are all selected to determine according to actual needs.Undertaken by dress by shown in Figure 1, and corresponding accessory is set, comprise that each by-pass valve control, connecting pipe wait until.Native system can be implemented the irrigation of common crops or greening etc.
