It is an object of the present invention a modular device for collecting rainwater formed by a single body consisting of different elements of different shapes and different materials.

The prior art does not provide the collection of rainwater by the users in condominiums. Therefore, the device, subject of the present invention, finds its use in this field as an absolutely innovative product.

The object of the present invention consists of conveniently using stored rainwater for watering pots located on the balconies of buildings, such as condominiums, by avoiding to use the drinking water provided by the water supply system.

Therefore, the advantage obtained by the device consists of avoiding the waste of drinking water for watering and, consequently, avoiding the costs associated to its use .

Another advantage is also due to the particular implementation of the anti-mosquito-intrusion and anti- evaporation system for collecting rainwater, wherein the modules are series arranged with a substantial saving of space occupied by the tubings . Said objects and advantages are all met by the anti- mosquito-intrusion and anti-evaporation system for collecting rainwater subject of the present invention, which is characterized for what is provided in the attached claims.

This and other characteristics will be better understood by the following disclosure of an embodiment shown by way of an illustrative and non-limiting example in the attached drawings, wherein:

- Figure 1 illustrates a perspective view of the device comprising four modules arranged in cascade that is positioned according to the rainwater flow direction;

- Figure 2 shows a perspective view of a single module comprising a box for collecting rainwater connected to the gutter by a rainwater pipe 3, with a direct connection or through the connection to the upper module, and to the corresponding use by means of another pipe 5;

- Figure 3 illustrates a partial vertical section of the end part of the rainwater pipe.

With reference to the Figures, 1, la, lb, and lc indicate a plurality of modules embodying the system subject of the present invention.

Obviously, in the shown example, the modules are in number of 4 because, with reference to the building to which they are installed, there are illustrated four balconies or, anyway, four floors and corresponding users which could use the system herein illustrated. Obviously, the described system can operate and can be applied also to a different number of modules, greater or smaller.

With reference to the building:

Each of said modules 1, la, lb and lc is formed by a box 2 for collecting rainwater, in which it is inserted a rainwater pipe 3 having its upper end 3a located at a height positioned in the upper half of the box 2 and the lower end 3b connected to the next module.

4 indicates the anti-mosquito-intrusion and anti- evaporation closing system as a whole. It comprises an electromagnetic foil 4a, pivoted at an hinge 4b, by a magnet 4c, which keeps the foil in a closed position, and by a leaf spring 4d, which returns the foil 2 in the closed position once the water has flowed to another module or to the sewer if the module is at the ground floor .

A pipe 5, having a diameter smaller than the rainwater pipe 3, can be connected to the use and transports the water stored in the box 2 to the corresponding use.

The pipe 5 has a valve, not shown.

At the end of this pipe, in correspondence of each use, it is possible to implement different kinds of use such as for example a drop-by-drop automatic watering or a standard tap.

Lastly, 6 indicates the gutter hanging from the strips of the roof which collects the rainwater and takes it to the first rainwater pipe 3 of the upper module, in the example the module indicated by lc.

The anti-mosquito-intrusion and anti-evaporation rainwater collecting system in the existing buildings can be fixed on the outside; or during their construction, it is embedded in the walls.

The collection box 2 can be provided with a gauge of the level of the water collected inside it, for example an inspecting eyelet.

Now, it will be described the operation of the device subject of the present invention following the references indicated in the figures.

The rainwater is collected by the gutter 6 and it channelled in the rainwater pipe 3 and is collected in the collecting box 2. When the water level in the box reaches the upper end 3a of the rainwater pipe 3, located at an height positioned in the upper half of the box 2, the excess water overflows and starts flowing to the next module.

At the lower end 3b of the rainwater pipe there is the anti-mosquito-intrusion and anti-evaporation closing system 4.

Until the flow rate inside the rainwater pipe 3 exerts on the closing foil 4a a force less or equal to the resultant of the force of the attraction magnet 4c and of the upward thrust exerted by the leaf spring 4b, the foil 4a remains in a closed position.

When the flow rate increases inside the collection box 2 and consequently the force acting on the closing foil 4a is greater than the force formed by the abovementioned forces, then the closing foil 4a rotates around the hinge 4b leaving the water free to flow to the next module .

We want to point out that the anti-mosquito-intrusion and anti-evaporation rainwater collection system is a self-adjusting device.

In brief, the anti-mosquito-intrusion and anti- evaporation rainwater collection system comprises a plurality of modules 1, la, lb, lc, each of them comprises :

a. a collection box 2,

b. a rainwater pipe 3 connecting the modules to each other,

c. an anti-mosquito-intrusion and anti-evaporation closing system 4, and d. a pipe 5 which can be connected to the corresponding use .

Said plurality of modules 1, la, lb, lc are connected to each other by pipes 3 and are located so that they receive a cascade flow of water.

The term "cascade flow of rainwater" means a substantially vertical flow, dropping by gravity and coming from the gutter 6 located above with respect to the first module lc and connectable to it by a first rainwater pipe 3.
