Abstract
The utility model discloses an automatic drip irrigation system of an agricultural greenhouse. The key technical points are as follows: the automatic drip irrigation system comprises a drip irrigation belt, an internal water supply device, a central controller and a humidity sensor as well as a rainwater collecting pond, wherein the drip irrigation belt, the internal water supply device, the central controller and the humidity sensor are arranged in the greenhouse; the rainwater collecting pond is arranged at the top of the greenhouse on the external side; the drip irrigation belt is respectively communicated with the internal water supply device and the rainwater collecting pond through water supply pipelines; an internal electromagnetic valve and an internal water supply pump are arranged on the water supply pipeline for communication between the drip irrigation belt and the internal water supply device; an external electromagnetic valve and an external water supply pump are arranged on the water supply pipeline for communication between the drip irrigation belt and the rainwater collecting pond; and the central controller communicates with the humidity sensor embedded in the soil through a signal collecting module in a connecting way and respectively communicates with the internal electromagnetic valve, the internal water supply pump, the external electromagnetic valve and the external water supply pump through a signal output module in a connecting way. According to the utility model, whether irrigation is needed or not can be determined according to water content in the soil, and rotted roots of crops due to water logging or withered crops due to drought are prevented; and moreover, rainwater can be also collected for drip irrigation, so that cost is saved.
Description
Technical field:
The utility model belongs to irrigation installation, is specifically related to a kind of agricultural greenhouse automatic drip irrigation system.
Background technology:
Drip irrigation technique is due to the advantage of its water-saving and yield-increasing, be used to more and more in canopy chamber irrigation, but existing drip irrigation can't be irrigated according to the actual water requirement of crop, easily like this make crop be subjected to waterlogging rotten or suffer from drought withered, its irrigation effect is poor, be unfavorable for the growth of crop, and waste water resource.Moreover, existing canopy chamber drip irrigation does not take full advantage of rainwater resource, can only allow rainwater be lost in vain within the season that rainfall is plentiful, and can't collect utilization to it, greatly wasted rainwater resource, if rainwater-collecting can be got up for drip irrigation, can greatly save water resource, save planting cost.
Summary of the invention:
The utility model is intended to overcome the deficiencies in the prior art, and a kind of agricultural greenhouse automatic drip irrigation system is provided, and it can be irrigated according to the actual water requirement of crop, also can collect rainwater and carry out drip irrigation, greatly saves water resource, saves planting cost.
Agricultural greenhouse automatic drip irrigation system of the present utility model, the technical scheme that adopts is: it comprises is located at canopy indoor irrigate band, private water supply device, central controller, humidity sensor and canopy outside in the rainwater-collecting pond that ceiling arranges, described irrigate band is communicated with by water supply line and private water supply device and rainwater-collecting pond respectively, and the water supply line that is communicated with irrigate band and private water supply device is provided with internal electrical magnet valve and private water supply pump; The water supply line that is communicated with irrigate band and rainwater-collecting pond is provided with external electromagnetic valve and outside supply-water pump, described central controller by signal acquisition module be embedded in humidity sensor connecting communication in soil, by signal output module respectively with internal electrical magnet valve, private water supply pump, external electromagnetic valve and outside supply-water pump connecting communication.
Preferably, described rainwater-collecting pond is provided with liquid level gauge, and liquid level gauge is by signal acquisition module and central controller connecting communication.
Preferably, the water supply line near the irrigate band is provided with filter.
Preferably, described rainwater-collecting pond is provided with overfall.
The beneficial effects of the utility model are: this agricultural greenhouse automatic drip irrigation system, can determine whether that according to the water content in soil needs irrigate, and prevent that crop is subjected to rotten of waterlogging or suffers from drought witheredly, guarantees the normal growth of crop; Also can collect rainwater and carry out drip irrigation, utilize fully rainwater resource, greatly save water resource, save planting cost.Its structural design advantages of simple, simple and efficient to handle, automaticity is high, time saving and energy saving, safe and reliable.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structured flowchart of the utility model electric control system.
Embodiment:
Below in conjunction with Fig. 1 and Fig. 2, embodiment of the present utility model is described further:
This agricultural greenhouse automatic drip irrigation system, comprise the rainwater-collecting pond 3 of being located at that canopy indoor irrigate band 1, private water supply device 2, central controller, humidity sensor and canopy outside arrange in ceiling, described irrigate band 1 is communicated with by water supply line and private water supply device 2 and rainwater-collecting pond 3 respectively, and the water supply line that is communicated with irrigate band 1 and private water supply device 2 is provided with internal electrical magnet valve 6 and private water supply pump 4; The water supply line that is communicated with irrigate band 1 and rainwater-collecting pond 3 is provided with external electromagnetic valve 7 and outside supply-water pump 5, described central controller by signal acquisition module be embedded in humidity sensor connecting communication in soil, by signal output module respectively with internal electrical magnet valve 6, private water supply pump 4, external electromagnetic valve 7 and outside supply-water pump 5 connecting communications.Rainwater-collecting pond 3 is provided with liquid level gauge, and liquid level gauge is by signal acquisition module and central controller connecting communication.Water supply line near irrigate band 1 is provided with filter 8.Rainwater-collecting pond 3 is provided with overfall.
This embodiment is carried out Real-Time Monitoring by humidity sensor to the moisture of soil, and Monitoring Data is fed back to central controller by data acquisition module, compare with the predefined setting value that is suitable for the soil water content of plant growth, when the numerical value of monitoring less than when setting value, central controller sends instruction so that both start to inner supply-water pump 4 and internal electrical magnet valve 6 respectively, private water supply device 2 is supplied water for irrigate band 1, crop is carried out drip irrigation; When the moisture content value in soil approached or equals to set value, central controller cut out private water supply pump 4 and internal electrical magnet valve 6, and private water supply device 2 stops supplying water for irrigate band 1, stops crop being carried out drip irrigation.When running into the rainfall sky, 3 pairs, rainwater-collecting pond rainwater is collected, when crop needs drip irrigation, central controller starts outside supply-water pump 5 and external electromagnetic valve 7, rainwater-collecting pond 3 is replaced private water supply device 2 and is supplied water for irrigate band 1, thereby utilize fully rainwater resource, reach the purpose of water-saving irrigation.Liquid level gauge on rainwater-collecting pond 3 can carry out Real-Time Monitoring to the water level in it, and send Monitoring Data to central controller, only have after the water level in rainwater-collecting pond 3 reaches certain value, central controller just starts outside supply-water pump 5, prevents from making because the water level in rainwater-collecting pond 3 is too low outside supply-water pump 5 idle running to damage with this.
