Description

   Water-saving and anti-blocking floating automatic irrigation system   

The invention provides a water-saving and anti-blocking floating automatic irrigation system using low-pressure or gravity irrigation. There is a floating body element in the floating device and floating watering device of the system. If the liquid flows downward, the floating body element blocks the water outlet as the liquid moves downward. The liquid can only pass through the small water-conducting hole next to the water outlet. Outflow, the flow is relatively reduced, and the pressure is also reduced. If there is too much liquid in the main pipe and the pressure is too large, multiple floating devices can also be connected in series to reduce the liquid volume and pressure. If the valve is closed or the soil is saturated with water, the specific gravity of the floating body element is smaller than that of the liquid, so it floats upwards. The floating body element floats upward to disturb the liquid, remove residues, and avoid blockages. In addition, when the soil moisture is saturated, the floating element of the floating watering device will float up. In addition to disturbing the liquid to remove residues, and preventing the liquid from flowing into the device, it will flow to the device where the soil is not saturated, so that the soil moisture can be uniform. Sex. Therefore, the floating device and the floating watering device are installed in the main pipe, which can reduce the liquid flow rate and also discharge the residue to prevent clogging.

The floating ventilating device can be installed in the main pipe and the tank to remove the gas trapped in the tube or the tank. If the liquid level rises, the sliding floating element in the device will rise to the leak-proof gasket above. It is discharged from the top and is attracted and strengthened by the magnetic force of the sliding floating body element and the magnet of the fixed ventilation ring to prevent the liquid from overflowing. Therefore, the device can allow the gas to be smoothly discharged without allowing the liquid to overflow.

The various control valves of the adjusting barrel device are used to control the flow of liquid in and out to achieve the amount of liquid required by the plant for irrigation; the floating ventilation device and the proportional control valve on the device allow gas to pass through the floating ventilation device and the ratio When the control valves of the water inlet are all closed, the device can use the proportional control valve to control the amount of gas in and out to control the speed of the liquid flow; the filter of the device is used to filter the impurities in the liquid; a plurality of The detection display detects the liquid level, pH value and composition of the liquid, and the signals displayed by the plurality of displays are transmitted to the control device, so as to more accurately control the liquid required for irrigation of the plants.

The signals from the plurality of detection displays are transmitted to the control equipment, which controls the opening and closing times of the plurality of control valves of the regulating barrel device, and uses the time required for the switch to regulate the required liquid pouring amount; it can also be remotely controlled by remote control. The equipment, through a control interface, remotely adjusts a plurality of control valves of the barrel to achieve a more accurate and rapid control of the pouring amount.

At present, the drip irrigation technology developed in Israel is relatively water-saving, but the water quality requirements are also high. As long as the filter device is not regularly flushed, it is easy to cause pipeline blockage and affect the irrigation system. In addition, due to the high investment costs and equipment maintenance that requires training, it is currently only suitable for the cultivation of high cash crops, which is difficult to promote on a large scale. Although many parties have devoted themselves to the design of the dropper to reduce obstruction, it still cannot prevent obstruction.

Referring to FIG. 9, a trace irrigation technology recently released in mainland China. The core of the technology is a water-saving element that is a trace irrigation head device. The device includes a capillary tube that conducts water and a trace irrigation film with a filtering function. The water control head is buried near the root system of the plant, and one end of the capillary bundle is connected to the water-filled pipe, and the other end is connected to the capillary tube of the soil. Water absorption by plants causes the water around the root system to decrease, and the water in the water control head flows around the root system by means of capillaries. this There are two disadvantages to this technique. (1) The turbulence caused by this method can exclude light slag with a smaller specific gravity than liquid, but heavy slag with a larger specific gravity than liquid can still not be easily removed, and it is easy to settle in the trace irrigation film. Cause blocking. (2) Excluded light slag still flows in the tube, and it is not discharged outside the tube. Over a long period of time, the light slag in the tube gradually increases, or it will cause blockage.

In view of this, the floating automatic irrigation system of the present invention is water-saving and anti-blocking. The liquid is discharged out of the pipe, and by the way, residues such as light slag and heavy slag are discharged out of the pipe together, and there is no accumulation effect. And the use of floating body elements to increase disturbance and avoid blockages. In addition, the investment cost is reduced, the conversion cost of the existing irrigation system is small, and the installation and maintenance are easy, which is suitable for planting of various plants.

First open the liquid fertilizer control valve 42 to allow the liquid fertilizer to flow into the storage tank 48, and then open the water inlet control valve 41 to allow the water to flow into the storage tank 48. At this time, the properties of the liquid are detected by the display A46 and the display B47. The detection signal is transmitted to the control device 51. Referring to FIG. 8, the main control device 66 and the control interface device 62 of the control device 51 receive the input signals 64 of the plurality of detection displays, and pass through the logic of the main control device 66 and the control interface device 62. After the calculation, it is converted into a control signal 65, and the remote control device 63 or the main control device 66 is used to input the control signal 65 to control the opening and closing times of the water inlet control valve 41 and the liquid fertilizer control valve 42 to achieve the optimal irrigation amount of the plant.

When the liquid flows out of the storage tank trough 48, the coarse slag is initially filtered through the filter 44 and flows to the floating device 1, see FIG. 1. At this time, the floating element A13 of the device flows downward with the liquid, and instantly blocks the water outlet. It is limited to the outflow of the water-conducting small hole 15 beside the water outlet, which reduces the liquid flow and pressure.

The liquid flows into the floating body watering device 2 with the main pipe 5.

When the gasket C36 is leaked, the magnet 34 above the element and the magnet 34 of the fixed ventilation ring 33 attract each other, which enhances the prevention of liquid overflow.

After watering for a period of time, the moisture in the soil 52 is gradually saturated. At this time, the floating body element B25 in the floating device 1 and the floating watering device 2 has a smaller specific gravity than the liquid, so it floats up and disturbs the liquid in the device to remove the residue by disturbance.
