ES2718116A1 - Modular capillary irrigation device based on PET bottles (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Modular irrigation system by capillarity based on pet bottles. This device arises from the need to avoid the loss of rainwater that falls on the fields by evaporation, especially in areas that suffer higher temperatures. To this end, this device has been designed consisting of a minimum of 4 reusable and cut-out bottles, placed vertically and in the form of a row, in such a way that it is capable of collecting rainwater or sprinklers through an upper module (1) in the form of petals optimized to collect the maximum amount of water. Said water passes through the plug to the module 2. In case of extreme rain, this module 2 has holes in its upper part to release the excess water. As can be seen in figure 2. once the water stored in module 4, the irrigation is produced by capillary action of the absorbent material from module 4 to the earth surrounding the device connected through module 3.

Description

DESCRIPTION

Modular capillarity irrigation device based on PET bottles.

Technical sector

Environmental Sector, Recycling of PET bottles, Use of rainwater.

From time to time, Spain and specifically, drier regions such as Andalusia or Extremadura, suffer long periods of drought that cause a considerable loss of water from reservoir water to attend to the irrigation of large areas of cultivation. The problem in crops is aggravated because in these areas with higher temperatures and suffer more hours followed by sun (especially in summer), there is a greater degree of evaporation of the water from the ground. That is, much of the water used for irrigation, is quickly lost by the natural evaporation that occurs in the soil itself.

Background of the invention

Our idea is to design a simple rainwater collector (or irrigation water) that prevents rapid evaporation and constantly watering and by natural physical phenomena the surrounding land in which it is "planted" (grounded). , said device, has to be done in a simple way with the intention of taking advantage of and reusing one of the most generated waste today, PET bottles (plastic water bottles, soft drinks, etc ...) transparent.

As a background we have a device, consisting of 3 modules (PET bottles) that collected rainwater underground, being absorbed with a sodium polyacrylate type material (material that baby diapers usually carry) After evaporation inside, subsequent condensation on the inner walls of one of the modules, and finally by fall towards the holes that are in contact with the earth in which the device was planted, it ended up wet. However, tests showed that evaporation was insufficient. Not to mention that it was not well seen to use a synthetic absorbent material to irrigate farmland.

Explanation of the invention.

The new invention consists of a modular device consisting of several linearly placed bottles reused vertically of the PET type (water, soft drinks, etc.) that together allow rainwater to be collected by itself or filled directly with tap water . A minimum of 4 modules (bottles) can be placed vertically, although more bottles could be placed to perform different functions (which are currently being studied).

The lower module (PET bottles) (sketch module 4) is completely buried in the ground to protect the collected water from rapid evaporation. From this module, some threads ascend upwards through which the water rises by capillarity to module 3. These threads exit through some holes towards the earth to moisten it. The threads can be of different previously selected fabrics (wool, absorbent cloth, etc.).

Module 1 (water trap) is activated to collect rainwater or sprinklers. The bottle is trimmed to collect the maximum amount of water possible.

Module 2 (filtration module) is used to slowly pass the water from module 2 to 3 and 4. In this way, in case of extreme rain said module 2 would cause excess water to flow out through holes that have on top.

Modules 1, 2 and 3 have a cap of their own bored bottle with a certain diameter to control the flow of water that reaches 4. These modules are embedded and sealed with heat to maintain their vertical stability. Module 4 joins 3 through the mouths of the bottles.

Preferred Embodiment of the Invention

The invention is based on the placement of PET bottles in such a way that by itself it is capable of collecting rainwater, storing and capillarizing the land where it is planted autonomously and without extra energy expenditure. The 4 modules are arranged to perform a different function already described.

This invention is capable of industrial application as an irrigation device in arable land or forest areas. It involves placing a device for each plant planted to provide water in a controlled manner. Also in restocking areas of hard to reach places.

It would be to place a holding stick to the growing plant and add a MODULARPET-IRRIGATION as an extra water support. Therefore, the possibility of producing it in large quantities and marketing it is feasible.

Claims (4)

CLAIMS The irrigation device consists of 4 PET bottles placed 3 inverted and trimmed (they are above the ground level) that carry the collected water to the 4th bottle, which is connected to the rest of the row of bottles in vertical and low land. Water from module 4 (underground) rises to module 3 and naturally accesses through holes to the surrounding terrain where the device is planted. 1. Irrigation device (1) of 4 modules that irrigates by capillarity with any type of material in the form of threads that carries water from module 4 to the ground through module 3. 2. Irrigation device (1) of 4 modules that irrigates by evaporation, condensation and fall of the water stored in module 4 through holes in module 3 without wires. Said module 4 may or may not contain other material that causes water to evaporate inside more slowly. 3. Device (1) according to any of claims 1 or 2 to which more modules (more PET bottles) are added or removed that can perform another function within its structure. 4. Irrigation device (1) according to any of claims 1, 2 and 3 made with any material other than PET bottles, having the same operation.
