DESCRIPTION

PORTABLE SYSTEM OF PLUVIAL WATER CATCHING SECTOR OF THE TECHNIQUE

The invention referred to in this document falls within the sector of the design and search for viable, low-cost solutions for the collection of rainwater intended for human consumption, due to the shortage of drinking water in low-resource areas water.

BACKGROUND OF THE INVENTION

Throughout history, human beings have used terrestrial surface water for their own consumption, cleaning and hygiene, agricultural activities, as a source of energy, etc. In addition, for more than 5000 years, there is evidence of systems of rainwater harvesting oriented to its use in agriculture At present, there are numerous rainwater harvesting systems, most of them implemented in the construction of houses located in areas with scarcity of water resources.

Some of these systems are very developed and the water passes through filters to enter directly into the network of pipes for human consumption of the home where it is implemented. However, these types of collectors have a very high cost of manufacturing and implementation in the living place.

For this reason, it is necessary to develop appropriate systems that serve to supply drinking water and that are possible to manufacture at a low cost, also being able to fold and transport it with ease, reducing to the maximum the necessary maintenance The type of rainwater collection system that is sought, it can solve the lack of means to obtain potable water in the world with scarce economic resources, where there is no adequate supply of water resources, or, the available water is not potable. Likewise, they can be useful in countries developed, in the domestic environment, in applications such as irrigation, car washing or personal hygiene.

EXPLANATION OF THE INVENTION

The present invention is intended to take advantage of the ability of waterproof fabrics or tarps not to let the water they receive pass through. This aspect, together with the correct presence of a runoff slope, which directs all the collected water to a spill point or sink, similar to a conventional drain. The water poured at that point, will pass through a pipe, preferably made of a PVC type polymeric material, suitable for contact with water intended for human consumption, which will be responsible for taking it to the tank, where it will be stored.

To achieve this, the developed system has the following characteristics: It consists of a structure or frame, formed by stakes or struts, which are semi-buried in the ground where the device is arranged, so that they remain fixed only when the system is used These stakes or props,

They will preferably be made of a wood material. Said structure or frame, will be formed by 10 stakes or struts, arranged in plan under a rectangular geometry, in such a way that the two sides of greater length have four stakes or struts, and that will hold together a flexible collection surface or impermeable canvas , so that said canvas is slightly recessed towards the geometric center of the catchment surface to facilitate water collection

To join the structure or frame with the flexible and impermeable collection surface, the latter will have, on its perimeter, a set of rings or pots that will allow its fixation to the stakes or struts that constitute the structure or frame of the system. These metal rings or pots will be riveted to the flexible surface, so that they leave a hole in it. These pots, will be used to fix the flexible waterproof surface of catchment to each one of the stakes or struts by means of hooks nailed to each stake and to pass through them ropes or rigid or flexible ropes that, in turn will be rolled up to each of the stakes or struts that make up the structure or frame, thus obtaining the necessary support on the collection surface.

In order to achieve the collection and storage of the maximum possible volume of rainwater, one or more tanks are available, of greater or lesser volume and / or interconnected with each other, under the principle of communicating vessels, below the collection surface. , either on the surface of the land or half buried therein.

In addition, and to ensure that the collected water is directed to the inlet of the tanks, a drainage system is provided, formed by a water inlet or sump, preferably metallic, similar to those used in conventional drains, connected to a pipe flexible or down, which allows it to be folded depending on the position of the tank, preferably made of a PVC type polymeric material, suitable for coming into contact with water intended for human consumption. The connection between the sump mouth and the flexible downpipe, must be attached to each other, as a sandwich, to the flexible waterproof surface of collection, to which a circular cut will have previously been made, to allow the passage of the collected water. of storage of the collected water, it will have a lid, which will have a thread type device to join at the end of the described downspout hose.

5 In addition, the maximum height of the tank must be less than the height at which the sump is located on the flexible collection surface; In addition, the downpipe must have a length less than the difference in heights mentioned. In this way, the connection between the end of the downpipe and the tank cover will cause the area of the collection surface near the drain to move down. This displacement or tightening of the flexible waterproof collection surface, causes an inverted cone shape as a whole in the collection surface, which in turn assumes the optimum surface for the runoff of the collected water, directing it towards the sump, and of there to the flexible downspout.

Finally, the placement of the drain or sink cannot be done in the center of the catchment surface, but it must be moved to the side, in order to achieve the most optimal rainwater collection.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the aforementioned figures, it can be seen how the portable rainwater collection system is constituted by four main subsets: the structure or frame, the surface of rainwater collection, the drain or sump, and the tank, in charge of collected water storage.

The structure or frame (1), has ten stakes or struts (2), preferably made of wood, arranged in plan under a rectangular geometry, and half buried in the ground. In this way, the ten stakes or struts (2) support the rest of the device.

This structure or frame (1) is joined by a flexible collection surface or canvas (3), made of a waterproof material, which is responsible for collecting rainwater. The connection between structure or frame (1) and flexible waterproof collection surface (3), is facilitated by two different elements. First, the flexible collection surface (3) incorporates, at its perimeter, at least ten rings or riveted metal pots eight riveted metal cylinders (4), at least one for each stake or strut (2) and arranged close to each of them. These riveted metal diados (4), leave in their inner diameter a hole that passes through the flexible waterproof surface of collection (3). Secondly, each of the stakes or struts (2) a rigid or flexible rope or tie (5) is wound, at the end of which it incorporates hooks that are subject to riveted metal diados (4). This type of device is colloquially known as “octopus.” With the device already explained, an awning type structure would be obtained, capable of collecting rainwater. However, the purpose of the invention is the collection and storage of This water, for this reason, a reservoir (6) that can be on the surface of the surface is disposed within the area of land that delimit the stakes or struts (2) and, below the flexible impermeable surface of catchment (3). land or semi-buried, have greater or lesser volume, or be connected to other secondary tanks; and whose purpose is the storage of collected water On the other hand, the flexible waterproof surface of collection (3), incorporates a drain or sink (7), preferably made of a metallic material, which in turn is attached, leaving a piece of flexible flexible surface for collection (3) in a sandwich-like medium, to a flexible downpipe (8), preferably manufactured in a

5 polymeric material The function of this device is to collect the water collected by the flexible waterproof collection surface (3), and take it to the tank (6), where it will be stored for later consumption.

To achieve this, the lower end of the downcomer flexible pipe (8), will be connected to the tank (6) by means of a threaded joint and through a cover (9), located on the tank (6). In addition, for optimum water collection and storage, the drain or sump (7) will be disposed of the geometric center of the flexible waterproof collection surface (3), and will be arranged, thanks to the joint between the lower end of the the flexible downpipe (8) and the cover (9) of the tank, in a parallel plane and of less height than the rest of the flexible flexible surface of 15 pick-up (3), causing in it a cone-shaped shape inverted by tightening thanks to the flexible downpipe (8) and consequently an optimum runoff surface for the collected water
