Description

Irrigation pipe using a wick

[0001] The present invention relates to an irrigation pipe, and more particularly, to an irrigation pipe that supplies moisture using a wick made of an absorbent material.

[0002] Typically, irrigation pipes are used to supply water to crops such as field crops, fruit trees, and flowers, whether grown in open fields or in greenhouses. Typically, one end of an irrigation pipe is connected to a pump installed in a well or river, while the other end is installed in the field, fruit tree, or flower garden.

[0003] A conventional drip irrigation pipe is made up of a pipe body having a cylindrical cross-section with a water channel formed inside, and through holes are formed at regular intervals along the length of the pipe body to communicate with the water channel, so that water is ejected through these through holes when the water pump is operated.

[0004] Therefore, in conventional irrigation pipes, the water supply is controlled depending on whether the water pump is operating. That is, when the water pump is operating, water is supplied, and when the water pump is stopped, water supply is stopped.

[0005] Furthermore, depending on the elevation of the cultivation area, if the irrigation pipe is located at a high elevation, water is sprayed weakly through the penetration holes. If located at a low elevation, water is sprayed strongly. Specifically, because water flows from higher elevations to lower elevations, irrigation is insufficient in higher elevations and excessive amounts are supplied to lower elevations, making water supply management difficult and wasting water.

[0006] In addition, conventional irrigation pipes have a problem in that water is supplied through the through-holes only while the pump is operating, so the pump must be operated continuously for the entire irrigation time required by the crop, which consumes a lot of energy.

[0007] In addition, conventional irrigation pipes have a problem in that the water supply is blocked when the roots of surrounding plants or fine clay from the soil enter through the penetration holes.

[0008] The purpose of the present invention is to provide an irrigation pipe that can maximize irrigation efficiency by preventing water supply blockage due to the inflow of roots or fine clay.

[0009] Another object of the present invention is to provide an irrigation pipe that can solve the problem that a large amount of moisture diffuses into soil pores during the initial stage of water supply through the irrigation pipe, while the amount of moisture supplied decreases as the distance increases.

[0010] Another object of the present invention is to provide an irrigation pipe using a wick, which can solve the problem of a limitation in the water supply height in existing wick irrigation using capillary phenomenon.

[0011] In order to solve the aforementioned problem, the present invention provides an irrigation pipe using a wick including a wick made of a fiber material and an outer shell that wraps the outer side of the wick.

[0012] According to one feature, a plurality of exhaust holes can be formed on the outer surface of the above appearance.

[0013] According to another feature, the outer shell is wound in a coil shape to have multiple layers and extends in the vertical direction, and a temporary moisture storage space can be formed in each layer of the outer shell.

[0014] According to another feature, the exterior may include an upper portion having an end bent downwards, a lower portion having an end bent upwards, and a connecting portion formed between the upper portion and the lower portion.

[0015] According to another feature, a plurality of the above-mentioned exteriors are continuously connected in the height direction to form a plurality of layers, and a temporary moisture storage space can be formed at the lower part of the above-mentioned exteriors.

[0016] In addition, in order to solve the aforementioned problem, the present invention provides an irrigation pipe using a wick, which includes a body in which a space is formed inside and a protrusion having a hollow portion in the center of the bottom surface is formed to protrude upward, and a wick made of a fiber material inserted into the hollow portion of the protrusion.

[0017] According to one feature, the upper end of the protrusion is formed in a shape that is bent downward at a predetermined angle, the upper end of the wick extends from the bottom surface to a predetermined height above through the protrusion, and the lower end of the wick can extend to the lower part of the body through the protrusion.

[0018] According to another feature, when a plurality of the above bodies are stacked in the vertical direction, moisture stored in the lower body can be supplied to the upper body through the upper wick.

[0019] In addition, in order to solve the aforementioned problem, the present invention provides an irrigation pipe using a wick including an inner tube having a hollow shape and a plurality of holes formed on an outer surface, and a wick made of a fiber material formed to wrap around the outer side of the inner tube.

[0020] According to one feature, the outer surface of the wick may further include an outer surface having a plurality of exhaust holes formed on the outer surface.

[0021] According to the irrigation pipe using a wick according to the present invention, the phenomenon of water supply blockage due to the inflow of roots or fine clay can be prevented, thereby maximizing irrigation efficiency.

[0022] In addition, according to the irrigation pipe using a wick according to the present invention, a certain amount of moisture can be evenly supplied to the surrounding soil over the entire length of the irrigation pipe.

[0023] In addition, according to the irrigation pipe using a wick according to the present invention, water can be supplied from a low place to a high place using the wick without being limited by the water supply height due to capillary phenomenon.

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the embodiments described below are merely intended to be detailed enough to enable those skilled in the art to easily practice the invention, and are not intended to limit the scope of protection of the present invention. In describing various embodiments of the present invention, components having the same technical features will be designated by the same reference numerals.

[0035] FIG. 1 is a perspective view of an irrigation pipe using a wick according to a first embodiment of the present invention.

[0036] As illustrated in FIG. 1, an irrigation pipe (hereinafter, “irrigation pipe”) (100) using a wick according to the first embodiment of the present invention includes a wick (200) and an outer shell (300) surrounding the wick.

[0037] The wick (200) is made of an absorbent material having a density that allows capillary action of moisture to be realized. For example, the wick (200) may be made of a fiber material of a predetermined length with numerous capillaries formed inside. Here, a capillary tube refers to a tube having an inner diameter small enough to transport a small amount of liquid through capillary action.

[0038] The exterior (300) is formed to surround the outer side of the wick (200), and a plurality of exhaust holes (310) are formed through the outer surface of the exterior (300).

[0039] When an irrigation pipe (100) according to the first embodiment of the present invention is buried underground and water is supplied from one side of the irrigation pipe (100), moisture is transferred to the opposite side of the irrigation pipe (100) through the wick (200). The moisture transferred in this way is supplied to the surrounding soil in a drip irrigation manner through the discharge hole (310) of the outer surface (300).

[0040] According to the first embodiment of the present invention, irrigation efficiency can be maximized by burying an irrigation pipe (100) around a target plant to be irrigated. In addition, since the wick (200) is surrounded and protected by the outer shell (300), tree roots or fine clay in the surrounding soil can be prevented from penetrating the wick (200) and clogging the pipe, and there is an effect of evenly supplying moisture through the discharge hole (310) over the entire length of the irrigation pipe (100).

[0041] Figure 2 is a diagram showing the state of use of an irrigation pipe using a wick according to the first embodiment of the present invention.

[0042] According to the first embodiment of the present invention, a plurality of irrigation pipes (100) can be branched from one irrigation pipe (100) in a form in which the wicks (200) are intertwined and connected to each other.

[0043] For example, in the embodiment illustrated in FIG. 2, the first irrigation pipe (100) is arranged in one direction, and an example is illustrated in which the second irrigation pipe (100) and the third irrigation pipe (100) are branched in directions perpendicular to the first irrigation pipe (100) from one side of the first irrigation pipe (100).

[0044] At this time, the first irrigation pipe (100) has the outer surface (300) of some sections removed to expose the wick (200), and the wicks of the second irrigation pipe (100) and the third irrigation pipe (100) are intertwined with the wick (200) of the first irrigation pipe (100) and combined. In this case, moisture flowing along the first irrigation pipe (100) can flow into the second irrigation pipe (100) and the third irrigation pipe (100) through the intertwined wicks (200), and there is an advantage in that the irrigation route can be easily set or changed without separate pipe construction or pipe installation. In the irrigation pipe where the wick (200) is exposed in some sections, the part where the end and the wick ((200) come into contact can be wrapped with tape (312) to finish.

[0045] The number of irrigation pipes (100) branching from one irrigation pipe (100) can be appropriately selected as needed, and it is to be noted in advance that branching the movement path of moisture by mutually connecting wicks (200) in this way can be equally applied not only to the above-described embodiment but also to the following embodiment using wicks (200).

[0046] Fig. 3 is a cross-sectional view of an irrigation pipe using a wick according to a second embodiment of the present invention.

[0047] The irrigation pipe (100a) according to the second embodiment of the present invention is similar in overall configuration to the irrigation pipe (100) of the first embodiment described above in that it includes a wick (200) and an outer shell (300a) that surrounds the outside of the wick (200). However, it differs from the first embodiment described above in that it is formed by being extended while being wound in a coil shape.

[0048] Hereinafter, the irrigation pipe (100a) according to the second embodiment of the present invention will be described in detail, focusing on the differences from the first embodiment described above.

[0049] According to the second embodiment of the present invention, as illustrated in FIG. 3, the outer shell (300a) is formed to extend in the vertical direction while being wound in a coil shape to have multiple layers, and at this time, the wick (200) inside the outer shell (300a) is also extended while being wound in a coil shape along the longitudinal direction of the outer shell (300a).

[0050] The outer shell (300a) can be extended by being wound in the vertical direction multiple times, for example, in a circular shape, and one layer is formed each time the outer shell (300a) is wound in the vertical direction once. In the embodiment shown in the drawing, the layers are spaced apart, but if necessary, the lower part of the upper layer and the upper part of the lower layer may overlap in some section, such as when the lower part of the upper layer is positioned lower than the upper part of the lower layer.

[0051] Here, if the part where the outer surface (300a) is wound once to form one layer is called a 'coil part (320)', a temporary moisture storage space (330) is formed at the lower end of each coil part (320). That is, moisture flowing along the wick is temporarily stored by gathering at the lower end of the coil part (320), and the temporarily stored moisture is then sequentially supplied to the temporary moisture storage space (330) of the upper layer through the wick (200).

[0052] Accordingly, according to the second embodiment of the present invention, a temporary moisture storage space (330) is formed at each predetermined height of the irrigation pipe (100a), thereby overcoming the height at which moisture can normally rise by the capillary phenomenon of the wick (200), and supplying moisture to a higher point.

[0053] Figures 4 and 5 are diagrams showing the state of use of an irrigation pipe using a wick according to the second embodiment of the present invention.

[0054] As an example, as shown in FIG. 4, when the lower end of the irrigation pipe (100a) according to the second embodiment of the present invention is buried in an underground aquifer (10) and the upper end of the irrigation pipe (100a) extends to the surface layer (20), moisture in the aquifer (10) can be supplied to the surface layer (20) through the wick (200).

[0055] At this time, the moisture accumulated in the lower temporary moisture storage space (330) is sequentially supplied to the upper temporary moisture storage space (330) through the wick (200), and by appropriately adjusting the height between the upper and lower temporary moisture storage spaces (330), the limitation of the moisture supply height by conventional wick irrigation can be overcome. In other words, the moisture in the aquifer (10) formed deep underground can be drawn up to the surface layer (20) by utilizing the capillary phenomenon of the wick (200).

[0056] Moisture transmitted through the wick (200) is discharged to the outside through a discharge hole (310) formed penetrating the outer surface (300). At this time, the height of the discharge hole (310) can be appropriately selected as needed. For example, if moisture is to be supplied only to the surface layer (20), at least one discharge hole (310) can be formed only in the outer surface (300a) portion buried in the surface layer (20). In addition, if moisture is to be supplied evenly from the aquifer (10) to the surface layer (20), a plurality of discharge holes (310) can be formed over the entire length of the outer surface (300a).

[0057] In addition, the irrigation pipe (100a) extended to the surface layer (20) may be extended to a specific point where irrigation supply is required, or the irrigation pipe (100) of the first embodiment described above may be connected and extended. In this case, it is of course possible to bury a number of branch pipes over a wide area using the embodiment described above with reference to FIG. 2.

[0058] Meanwhile, the embodiment illustrated in FIG. 5 illustrates an example of supplying moisture to the surface layer (20) from a storage tank (30) buried in the ground and storing rainwater or sewage water, using an irrigation pipe (100a). In this case, if the storage tank (30) in which moisture is stored has a discharge hole (310) of the exterior (300), the discharge hole (310) also functions as an inlet to allow moisture from the storage tank (30) to easily flow in. Meanwhile, it goes without saying that the irrigation pipe (100a) may be connected to a water pipe (not shown) buried in the ground through which rainwater or sewage water flows instead of the storage tank (30).

[0059] Fig. 6 is a cross-sectional view of an irrigation pipe using a wick according to a third embodiment of the present invention.

[0060] The irrigation pipe (100b) according to the third embodiment of the present invention is similar in overall configuration to the irrigation pipe (100) of the first embodiment described above in that it includes a wick (200) and an outer body (300b) that surrounds the outside of the wick (200). However, it differs from the first embodiment described above in that the upper and lower ends of the outer body (300b) are bent downward and upward, respectively, to form an overall 'C' shape.

[0061] Hereinafter, the irrigation pipe (100b) according to the third embodiment of the present invention will be described in detail, focusing on the differences from the first embodiment described above.

[0062] According to the third embodiment of the present invention, as illustrated in FIG. 6, the exterior (300b) is formed in a 'C' shape. At this time, the exterior (300b) includes an upper portion (301) with an end bent downwards, a lower portion (302) with an end bent upwards and facing the upper portion (301), and a connecting portion (303) formed between the upper portion (301) and the lower portion (302).

[0063] A wick (200) is inserted inside the outer shell (300b), and a temporary moisture storage space (330) is formed at the lower end of the outer shell (300b). That is, moisture flowing along the wick (200) is temporarily stored by gathering at the lower end of the outer shell (300b).

[0064] Figure 7 is a diagram showing the state of use of an irrigation pipe using a wick according to a third embodiment of the present invention.

[0065] According to the third embodiment of the present invention, the irrigation pipe (100b) can be formed by combining multiple pipes in the vertical direction to form multiple layers, as shown in FIG. 7.

[0066] At this time, the lower part of the upper irrigation pipe (100b) and the upper part of the lower irrigation pipe (100b) are joined, and the joining method can be selected in various ways as needed, such as a fitting joint using a groove and a projection, a screw joint, or a joint using a separate joining member.

[0067] In this way, when a plurality of irrigation pipes (100b) are connected in a vertical direction in a continuous manner to form a plurality of layers in the height direction, the wick of the irrigation pipe (100b) extends from the temporary water storage space (330) of the corresponding irrigation pipe (100b) to the upper part of the temporary water storage space (330) of the upper irrigation pipe (100b). That is, the lower part of the wick (200) is immersed in the water accumulated in the temporary water storage space (330) of the corresponding irrigation pipe (100b), and the upper part of the wick (200) is positioned above the temporary water storage space (330) of the upper irrigation pipe (100b) at a predetermined interval. At this time, the lower part of the wick (200) of the lowest irrigation pipe (100) may extend to the outside of the outer surface (300b).

[0068] In this case, the moisture accumulated in the temporary moisture storage space (330) of the lower irrigation pipe (100b) is absorbed into the lower end of the wick (200), then rises along the wick (200) and drips from the upper end of the wick (200) to accumulate in the temporary moisture storage space (330) of the upper irrigation pipe (100b). That is, the moisture accumulated in the temporary moisture storage space (330) of the lower irrigation pipe (100b) is sequentially supplied along the wick (200) to the temporary moisture storage space (330) of the upper irrigation pipe (100b), and accordingly, by adjusting the gap between the temporary moisture storage spaces (330) of the upper and lower layers, the height at which moisture can normally rise due to the capillary phenomenon of the wick (200) can be overcome, and moisture can be supplied to a higher point.

[0069] Fig. 8 is a cross-sectional view of an irrigation pipe using a wick according to the fourth embodiment of the present invention.

[0070] The irrigation pipe (100c) according to the fourth embodiment of the present invention includes a body (400) having a space formed inside and a protrusion (410) formed in the center of the bottom surface, as shown in FIG. 8, and a wick (200) inserted into the hollow of the protrusion (410).

[0071] Here, the protrusion (410) is formed in the shape of a pipe having a hollow space, for example, and the upper end of the protrusion (410) is formed in a shape that is bent downwards at a predetermined angle. A wick (200) is inserted into the hollow space of the protrusion (410), and at this time, the upper end of the wick (200) extends from the bottom surface of the body (400) to a predetermined height above through the protrusion (410), and the lower end of the wick (200) extends to the lower part of the body (400) through the protrusion (410).

[0072] Fig. 9 is a cross-sectional view of an irrigation pipe using a wick according to the fourth embodiment of the present invention in a used state.

[0073] According to the fourth embodiment of the present invention, the irrigation pipe (100c) may be stacked in a plurality of vertical directions to form multiple layers, as illustrated in FIG. 9. At this time, the lower end of the upper body (400) is supported by the upper end of the lower body (400), and the lower body (400) and the upper body (400) may be mutually coupled in various ways, such as by fitting, screw coupling, or coupling using a separate coupling member.

[0074] As shown in Fig. 9, when a plurality of irrigation pipes (100c) are continuously connected in the height direction, the lower end of the wick (200) of the upper irrigation pipe (100c) extends to the bottom surface of the body (400) of the lower irrigation pipe (100c).

[0075] At this time, the lower end of the wick (200) of the lowest irrigation pipe (100c) can be inserted into the aquifer (10), the storage water tank (30) buried underground, or the inside of the water pipe, and a separate wick (200) can be inserted into the inside of the uppermost irrigation pipe (100c) by penetrating the outside of the body (400). The wick (200) inserted into the inside of the body (400) of the uppermost irrigation pipe (100c) has a lower end immersed in water collected on the bottom surface of the body (400), and an upper end can extend outside the body (400) to the surface layer (20).

[0076] In this case, moisture absorbed through the wick (200) of the lowest irrigation pipe (100c) is sequentially supplied from the lower irrigation pipe (100c) to the upper irrigation pipe (100c) through the wick (200) of each layer, and accordingly, by adjusting the height of the body (400), the height at which moisture can normally rise due to the capillary phenomenon of the wick (200) is overcome, and moisture can be supplied to a higher point.

[0077] That is, according to the irrigation pipe (100c) according to the fourth embodiment of the present invention, the irrigation height can be increased by continuously assembling a plurality of irrigation pipes (100c) in a modular manner, and thus, while manufacturing and installation are simple, the limitation of the irrigation height of the conventional wick irrigation method can be overcome.

[0078] Meanwhile, in the irrigation pipe (100c) according to the fourth embodiment of the present invention, when surface water flows into the top irrigation pipe (100c) or moisture is forcibly supplied, moisture can be filled into the body (400) of each layer through the wick (200) of each layer.

[0079] Meanwhile, according to the irrigation pipes (100a to 100c) according to the second to fourth embodiments of the present invention, moisture in a storage water tank (30) or a water pipe that is too deep to be irrigated by a conventional wick (200), or moisture in an aquifer (10) formed deep underground, can be drawn up to near the surface layer (20) and supplied as irrigation water. At this time, since the length of the irrigation pipes (100a to 100c) can be extended or branched as needed, the irrigation area can be easily expanded, and for example, it can greatly contribute to soil transformation in deserts.

[0080] Fig. 10 is a perspective view of an irrigation pipe using a wick according to the fifth embodiment of the present invention.

[0081] The irrigation pipe (100d) according to the fifth embodiment of the present invention has some similarities with the first embodiment described above in that it includes a wick (200) and an inner pipe (500), but it differs from the first embodiment described above in that the wick (200) is formed to surround the outer side of the inner pipe (500).

[0082] Specifically, the irrigation pipe (100d) according to the fifth embodiment of the present invention includes, as illustrated in FIG. 10, an inner tube (500) having a hollow shape and having a plurality of through holes (510) formed through the outer surface thereof, and a wick (200) made of a fiber material formed to surround the outer side of the inner tube (500).

[0083] Moisture flowing along the inner tube (500) is discharged to the outside through the perforation (510), and the moisture discharged through the perforation (510) is supplied to the surrounding soil through the wick (200).

[0084] In the case of the irrigation pipe (100d) according to the fifth embodiment of the present invention, since the hole (510) of the inner pipe (500) is wrapped by the wick (200), the penetration of tree roots or fine clay into the inner pipe (500) is prevented, thereby preventing the pipe from clogging in advance.

[0085] Fig. 11 is a perspective view of an irrigation pipe using a wick according to the sixth embodiment of the present invention.

[0086] The irrigation pipe (100e) according to the sixth embodiment of the present invention is similar to the irrigation pipe (100d) of the fifth embodiment described above in that it includes a wick (200) and an inner pipe (500), but is different from the irrigation pipe (100d) of the fifth embodiment described above in that the outer body (300) is formed to surround the outer side of the wick (200).

[0087] That is, the irrigation pipe (100e) according to the sixth embodiment of the present invention, as illustrated in FIG. 11, includes an inner tube (500) having a hollow shape and a plurality of through holes (510) formed through the outer surface thereof, a wick (200) made of a fiber material formed to surround the outer side of the inner tube (500), and an outer body (300) having a plurality of discharge holes (310) formed on the outer surface thereof while surrounding the outer side of the wick (200).

[0088] According to the irrigation pipe (100e) according to the sixth embodiment of the present invention, moisture flowing along the inner pipe (500) is absorbed into the wick (200) through the through hole (510), and the moisture absorbed into the wick (200) is supplied to the surrounding soil through the discharge hole (310) of the outer pipe (300).

[0089] Accordingly, according to the irrigation pipe (100e) according to the sixth embodiment of the present invention, the inflow of tree roots and fine clay into the inner pipe (500) is prevented by the outer body (300) and the wick (200), thereby maximizing the irrigation efficiency.

[0090] Although the embodiments of the present invention have been described above, it is understood that those skilled in the art will be able to make various modifications and implementations without departing from the scope of the claims of the present invention.

[0091] According to the irrigation pipe using the wick of the present invention, the phenomenon of water supply blockage due to the inflow of roots or fine clay can be prevented, thereby maximizing irrigation efficiency.

[0092] In addition, according to the irrigation pipe using the wick of the present invention, a certain amount of moisture can be evenly supplied to the surrounding soil over the entire length of the irrigation pipe.

[0093] In addition, according to the irrigation pipe using the wick of the present invention, water can be supplied from a low place to a high place using the wick without being limited by the water supply height due to capillary phenomenon.
