Definitions

  • the present invention refers to an irrigation device .
  • Saving water is especially important in the irrigation of plants, particularly for agriculture and gardening.
  • Drip irrigation is a widely-used irrigation modality that is efficient and saves considerable water.
  • Drip irrigation is an irrigation method that permits the distribution of small volumes of water to be applied directly to the area of influence of the roots, through a piping system and emitters or drippers.
  • the piping system or network allowing the distribution of water consists of a plurality of pipes or lines of different sizes and lengths that are connected to one another. Typically, water flows from a supply source through a main line, and is subsequently distributed from the main line to the different points of application, through a series of tubes and secondary pipes.
  • the most widely-used drip irrigation method consists of a series of micro tubes connected to a water distribution line that can be, in turn, connected to other main distribution lines.
  • the micro tubing comprises one or several holes, and water goes out through said holes in order to irrigate the adjacent soil zone.
  • a dripper is arranged in the connection between each section of micro tubing with the water distribution line, in order to regulate and control the flow rate of the supplied water .
  • a variant that partially solves this problem consists of using pipes made of porous material instead of micro tubes.
  • These porous pipes allow the water to be distributed in a more uniform manner, along their entire length.
  • the volume of liquid passing through the porous pipe and the pressure of the water in their interior will be greater. Therefore, the water flow rate applied using these porous pipes may be too high and may be concentrated in a non homogeneous way at specific sections of the same, for example, at the initial section.
  • the object of the present invention is to overcome the drawbacks of current devices known in the art by providing an irrigation device comprising a first line and a second line, which is connected to the first line and having a smaller diameter than that of said first line, characterized in that it comprises a third line made of a permeable material, which is connected to the second line in a movable manner with this third line having a larger diameter than that of the said second line.
  • the third line comprises an independent pipe made of a porous material.
  • the second line and the third line are connected to one another at one of their respective ends.
  • the resulting device permits the use of a porous or exudative pipe to distribute the irrigation water onto the soil in a homogeneous manner and with a reduced consumption.
  • the use of a micro tubing with reduced diameter between the main distribution line and the porous pipe results in a decreased water pressure and a reduced flow rate before reaching said porous pipe. This decrease in pressure and flow rate permits a homogenous distribution of water along the entire length of the porous pipe.
  • connection that is movable between the micro tubing and the porous pipe permits the easy and fast changing of the length of the micro tubing/porous pipe assembly, making it possible to arrange said porous pipe in different positions and to occupy the most convenient extension of land as desired.
  • the device comprises a connection element between the respective ends of the second line and third line.
  • connection element comprises a tubular conical body whose inner surface is pressure-fitted to the outer surface of the second line and whose outer surface is pressure-fitted to the inner surface of the third line.
  • the inner surface of the connection element that is pressure-fitted to the outer surface of the second line and the outer surface of the connection element that is pressure-fitted to the inner surface of the third line are both smooth.
  • connection element comprises a first narrower end to whose inner surface, the outer surface of the second line is pressure-fitted, as well as a wider second end to whose outer surface, the inner surface of the third line is pressure-fitted.
  • the inner surface of the first end of the connection element and the outer surface of the second end of the connection element are parallel to the longitudinal axis of said connection element.
  • connection element comprises an outer wall that extends perpendicularly with respect to the longitudinal axis of said connection element, with said outer wall being situated next to the outer surface of the connection element that is pressure-fitted to the inner surface of the third line.
  • the device comprises a ring whose inner surface is pressure-fitted to the outer surface of the third line, in the area corresponding to the inner surface of said third line that is pressure- fitted to the outer surface of the connection element.
  • connection piece permits the connection of the micro tube with the porous pipe in a simple and quick manner and with a mutual movement capacity.
  • the device comprises a drip element between the first line and the second line.
  • a dripper permits the additional regulation and control of the flow rate being supplied to the land. Additionally, the use of the micro tube between the main line and the porous pipe permits the connection of a conventional dripper between said micro tube and the main line, of the same type of those used in drip irrigation systems that only use micro tubes.
  • the incorporation of a dripper between the main line and the micro tube is not compulsory, since the connection between both pipes can be carried out directly, by means of a micro-insert or with another appropriate piece known in the art .
  • Figure 1 is a perspective schematic view of a device according to the present invention, showing the different steps of its component assembly
  • Figures 2 and 3 are perspective and sectional detailed views, respectively, showing the connection between a micro tube and a porous pipe of the device, according to the invention, in a disassembled state;
  • Figures 4 and 5 are perspective and sectional detailed views, respectively, showing the connection between a micro tube and a porous pipe of the device, according to the invention, in an assembled state; DESCRIPTION OF A PREFERRED EMBODIMENT
  • FIG 1 a schematic representation of an embodiment of an irrigation device according to the present invention is shown. Said figure shows several assembly steps of the components forming part of the device.
  • the device of the shown embodiment comprises a main or supply line 1, whose function is to transport water received from a supply source.
  • Said main line 1 can receive the water directly from the supply source or from other main lines (not shown) .
  • the main line 1 comprises a plurality of holes 2 on one of its sides, separated at a specific distance. Said holes 2 communicate the inner side of the main line 1 with the outer side, and they permit the exit of the water flowing trough said main line 1.
  • the irrigation device further comprises a dripper 3 that can be of any suitable type available in the art.
  • a dripper 3 that can be of any suitable type available in the art.
  • One of the ends of the dripper 3 is coupled to a corresponding hole 2 in the main line 1.
  • the dripper 3 permits the regulation of the flow rate of the water leaving the corresponding hole
  • the dripper 3 also comprises another outlet end to which one end of a micro tube 4 is pressure-coupled.
  • the micro tube 4 has a substantially smaller diameter than that of the main line 1.
  • the main line 1 and the micro tube 4 are made of an impermeable material, such as polyethylene.
  • the micro tube 4 is connected at its other end to one of the ends of a water permeable porous pipe 5 which has a larger diameter than that of said micro tube 4.
  • the porous pipe 5 may be made of polyester, and allows the water flowing inside of it to exit freely through its pores, along its entire length.
  • the porous pipe 5 is connected to the micro tube 4 through a connection piece 6 and a connection ring 7, whose characteristics and operation will be explained subsequently.
  • connection piece 6 has a substantially conical and tubular shape, and smooth inner
  • connection piece 6 comprises a first end 10 and a second end 11, with the first end 10 being narrower than the second end 11.
  • the piece 6 is hollow with longitudinal openings 12 and 13 at both ends 10 and 11, respectively .
  • connection piece 6 is parallel to the longitudinal axis L of said piece 6.
  • outer surface 15, corresponding to the second end 11 of the connection piece 6, is also parallel to the longitudinal axis L of said piece 6.
  • connection piece 6 further comprises an outer perimeter wall 16, arranged at the end 11 and extending perpendicularly with respect to the longitudinal axis L of said piece 6.
  • connection piece 6 is first arranged lengthwise, aligned with respect to the micro tube 4. Subsequently, one of the ends of the micro tube 4 is introduced into the piece 6 through the opening 13, until the outer surface of said end of said micro tube 4 contacts the inner surface 14 of the end 10 of the piece 6 and reaches or surpasses the opening 12.
  • the diameter of the opening 12, that is, of the inner surface 14, will preferably be slightly smaller than the outer diameter of the micro tube 4, in order to obtain a pressure coupling between the outer surface of the micro tube 4 and the inner surface 14 of the piece 6.
  • the micro tube 4 and the piece 6 are fixed in a watertight and reliable manner, maintaining the capacity for movement between them, as the micro tube 4 can slide lengthwise with respect to the piece 6, in both directions (see figures 1 and 5) .
  • the end 10 of the piece 6 is introduced into the porous pipe 5 until the inner surface of said porous pipe 5 makes contact with the outer surface 15 of the end 11 of the piece 6 and the end of said porous pipe 5 abuts the wall 16.
  • the wall 16 facilitates the positioning of the pipe 5, preventing the piece 6 from being excessively introduced into the same, potentially damaging the quality of the connection and its subsequent disassembly.
  • the diameter of the outer surface 15 of the piece 6 will preferably be larger than the inner diameter of the porous pipe 5, in order to obtain a pressure coupling between the inner surface of the pipe 5 and the outer surface 15 of the piece 6. In this way, the porous pipe 5 and the piece 6 are attached in a reliable manner.
  • connection piece 6 as seen in figures 4 and 5.
  • a retaining ring 7 may be mounted around the pipe 5 to press the area in which the inner surface of said pipe 5 and the outer surface 15 of the piece 6 are pressure-coupled.
  • the ring 7 allows for further improving the water-tightness of the connection, thus avoiding unnecessary water losses in said zone.
  • connection piece 6 apart from quickly and efficiently coupling the micro tube 4 and the porous pipe 5, the connection piece 6 also permits the relative movement between them. To carry out said movement, it is only necessary to slide the micro tube 4 lengthwise inside the piece 6, so as to vary the distance between the porous pipe 5/piece 6 combination and the main line 1 (figure 5) .
  • the porous pipe 5 can be placed in the most suitable position, depending on specific cases, without the need to add pipes or additional elements in order to achieve a greater reach or to cut the micro tube 4 or the porous pipe 5 to shorten its length.
  • connection piece 6 may have a purely conical shape, that is, without the presence of the surfaces 14 and 15 or the perimeter outer wall 16, in order to simplify its production.
  • connection piece 6 may be made out of any suitable material, e.g. plastic, such as polypropylene or polyethylene.
  • the difference of diameters between the main line 1, the micro tube 4 and the porous pipe 5 allows for a more efficient water distribution. Thanks to the smaller section of the micro tube, a reduction in water flow rate, load and pressure is produced in the same.
  • the water entering the porous pipe 5 from the micro tube 4 does so at a lower pressure and with less turbulence than that entering the main line 1, resulting in a better transfer to said porous pipe 5 and a more uniform distribution along the same.
