Description

Floating irrigation device

The present invention provides a floating irrigation device that utilizes low pressure or gravity irrigation to save water and block. When the liquid flows downward, the floating element in the hollow element of the device moves down with the liquid to block the drain port, and the instantaneous liquid can only flow out from the drain hole near the drain port, and the flow rate is relatively reduced. If the amount of liquid in the tube is too much, a plurality of devices can be connected in series to reduce the liquid flow. If the drain is extended and the drain has a spout, the device can be inserted into the soil for watering. And by disturbing the liquid in the hollow chamber of the hollow element by the floating element, the residue in the tube can be removed into the soil to avoid clogging. When the liquid is changed by the drain pipe, the liquid level of the hollow chamber of the floating irrigation device rises, and the liquid level rises, the floating element rises, and the water inlet is blocked; the gas in the pipe or the tank is trapped, and the gas can be smoothly discharged. For example, a fixing ring is added to the inlet pipe of the hollow element, and the fixing ring and the floating element are magnetized, and the magnets are attracted to each other to prevent leakage of water, and the liquid in the pipe does not overflow.

At present, the drip irrigation technology developed by Israel is more water-saving. However, the requirements for water quality are also high. As long as the filtration device is not regularly flushed, it is easy to cause pipe blockage and affect the watering system. In addition, because of the high investment cost and the maintenance of equipment maintenance, it is currently only suitable for planting high-yield crops, which is difficult to promote on a large scale. Although, many are dedicated to dropper design to reduce blockages, However, it is still impossible to prevent the blocking situation from occurring.

Referring to Figure 5, the recent development of trace irrigation technology in mainland China, the core of the technology is the water-saving component is a trace irrigation control head device, which consists of a capillary tube with water guiding and a trace film with filtering function. The water head is buried near the root of the plant, connected to the water-filled pipe at one end of the capillary beam and to the capillary of the soil at the other end. The water absorption of the plant causes the water around the root system to decrease, and the water in the water control head flows to the periphery of the root system by means of a capillary. The shortcomings of this technology are 2 points. (1) The turbulence caused by this method can eliminate the light slag which is smaller than the liquid, but the heavy slag which is larger than the liquid is still difficult to be excluded, and it is easy to precipitate in the trace film. Still causing blockages. (2) The light slag that is excluded still flows in the pipe. If there is no discharge pipe, it will accumulate for a long time, and the light slag in the pipe will gradually increase, which will still cause blockage.

The novel water-saving and anti-blocking floating irrigation device is suitable for irrigation of various plants, and is applicable not only to large-area planting but also to potted planting. In addition to improving drip irrigation and the obstruction of trace irrigation systems, gravity-based irrigation can be used to address the high cost of equipment construction and maintenance techniques required for general plant irrigation.

The floating irrigation device is used for irrigation to reduce flow, watering and venting, and the device comprises at least: (a) a hollow component: the inlet diameter and the drainage diameter of the hollow component are smaller than the hollow chamber, and there is a discharge port A plurality of drainage holes. The hollow member can also be modified into a detachable type, and the hollow member is disassembled into the hollow member A and the hollow member B, and the leaking member can be used at the joint to prevent water leakage, thereby facilitating cleaning of the hollow chamber. (b) A floating element: the floating element has a specific gravity smaller than the liquid, and the floating element may be of any geometric shape. The floating element moves up and down within the hollow chamber of the hollow element to disturb the liquid and prevent clogging.

The floating element of the floating irrigation device causes the element to move up and down in the hollow chamber of the hollow element to disturb the liquid by the internal liquid level change, to remove the residue and prevent the blockage; and the plurality of drainage holes beside the drain port of the hollow component of the floating irrigation device When the liquid flows downward, the floating element flows down, blocking the drain to prevent a large amount of liquid from flowing out, and only a small amount of liquid flows out from the drainage hole; when the liquid stops flowing, the floating element floats upward and the residue is drained. The mouth flows to prevent blockage. If there is too much liquid flow in the tube, a plurality of devices can be connected in series to reduce the flow rate.

The drain pipe of the hollow component of the floating irrigation device is lengthened, and the lengthened drain pipe has a plurality of watering nozzles, so that the floating irrigation device can be inserted into the soil for watering. If the soil moisture is saturated, the floating element will float up, preventing the liquid from flowing back into the device, and the liquid will flow to the floating irrigation device where the soil is not saturated.

When the liquid is changed by the drain pipe, the liquid level of the hollow chamber of the floating irrigation device rises, the floating element rises, the water inlet is blocked, and the gas in the pipe or the tank is trapped, and the gas can be smoothly discharged. For example, a fixing ring is added to the inlet pipe of the hollow element, and the fixing ring and the floating element are magnetized, and the magnets are attracted to each other to prevent leakage of water, and the liquid in the pipe does not overflow.

Installation of this floating irrigation device, whether in the indoor greenhouse or outdoors, whether it is sunny or rainy days, is applicable and can achieve the effect of water-saving non-blocking.
