    Wind generator electricity generator for umbrellas and umbrellas.
    5 Object and sector of the technique to which the invention relates
    The present invention relates to a wind generator generating electricity for umbrellas and umbrellas (1) for preferential placement in umbrellas and umbrellas, both handheld for portable use, and stationary for use in campsites, beaches, etc.,
    10 allowing electric power to be generated from wind energy captured by the fabric when it is extended; the device (1) stores the electrical energy in a battery for use preferably for recharging mobile phones, smartphones, tablets, electronic books, laptops, etc., as well as eg LED lighting; The device (1) allows the normal folding of the umbrella and umbrella.
    The invention is located in the technical sector of electrical engineering and fluid mechanics.
    General and closest prior state of the art
    20 The dictionary of the Spanish language (DRAE), in its 22nd edition, defines "umbrella" as a portable tool for shelter from rain, consisting of an axis and a rod covered with cloth that can be extended or folded; and defines "umbrella" as "sunshade", defining this as a kind of umbrella or umbrella used for
    25 shelter from the sun.
    An umbrella is an object to protect against rain; It is formed by a concave folding surface, usually made of waterproof or plastic cloth, attached to a structure of rods arranged around a central axis finished off in one of its
    3 Or ends by a bead that serves as support, and on the other hand finished in a handle or fist, suitable for carrying with one hand; There is a pocket version, which has rods that fold in two or more places.
    The theoretical wind power that develops the air flow captured by an umbrella or umbrella will be given by the following expression:
    1 3
    P = _ · p · S · v
    2 eo
    where: P is the power (W), p is the density of the air (kg / m3), S is the characteristic area 4 O (m2) and Veo is the wind speed (mis).
    For a circular catchment area, typical of an umbrella or umbrella, we will have:
    rr. D2
    S = -
    being: D the diameter of the extended fabric of the umbrella or umbrella.
    For an air density of 1.2 kg / m3, we will have:
    p = 047 · D2 • I see 3
    ,
    The air flow will travel through the interior of the fabric, through the concave part, until it reaches a wind collector (107), said air flow being redirected until finally reaching a wind turbine (1024). The energy of the air flow, except for the losses in its movement, will be constant, so that the power produced by the wind turbine (1024) is given by the following equation:
    where: P is the power (W), Cp is the power coefficient dependent on A, peripheral speed ratio (TSR), and ~, which is the pitch angle, D is the diameter of the extended fabric of the umbrella or umbrella (m), and I see is the wind speed (mis).
    The power coefficient Cp can reach the maximum theoretical value of 16/27 (0.59) which is the so-called Betz limit, although in practice the maximum value is given in two-bladed HAWT turbines being 0.47 ( Femández, 2009; Patel, 2006).
    For a Cp of 0.47, the mechanical power on the axis of the wind turbine (1024) is given by:
    p = 0.472 • D2. I see
    To calculate the specific power, we will use a D = ~ m, leaving:
    p '= 0.28 · see 3
    where: P 'is the specific power (W 1m2).
    E.g. for a Veo of 5 mi we will have a P 'of 35 W / m2 •
    The average power of a smartphone is 5 W, by 10 that with a square meter of cloth, that is to say 1.13 m in diameter, we will need a Veo of 2,615 mis; if we consider an electric generator performance (1029) of 0.9 then we will need a Veo of
    2.7 mis.
    It is unknown in the state of the art if there is a functionally similar device, although it solves the technical problems in a different way, as claimed by the present invention.
    In the closest state of the art we have the following documents: In the utility model document called DOl with publication number ESI074332U and presentation date 22.12.2010 and literally entitled: "Umbrella", an umbrella is described that presents the particularity of being equipped with solar panels
    5 to establish a power supply of a plug, connector or similar, to which different devices, devices or equipment can be connected for operation.
    These devices present a problem that focuses primarily on the following 10 aspects:
    - Rigid elements in contact with the waterproof fabric or canvas, causing weaknesses in it;
    15 - They require a plurality of auxiliary elements for fixing the different elements to the umbrella or umbrella, being therefore laborious assembly and disassembly;
    The device (1), which the invention prepares, fully and satisfactorily solves the problem set forth above, in each and every one of the different aspects mentioned. Detailed description of the invention
    25 Wind generator electricity generator for umbrellas and umbrellas (1) comprising the following elements with the following characteristics:
    - a first part called the wind collection and electricity generation subsystem (100) and whose function is to properly redirect the air flow
    3 Or captured by the fabric of an umbrella or umbrella and make it reach a wind turbine (1024), to make an electric generator (1029) drag in its turning movement in order to generate electrical energy;
    - a second part called storage and feeding subsystem
    35 electric (200) and whose function is to regulate the load and store the electrical energy from an electric generator (1029) in a stage of storage and power supply (2001), as well as power an electric receiver by means of a plug (2005).
    4 O The technical advantages, with respect to the current state of the art, presented by the invention are:
    ./ There are no rigid elements in contact with the waterproof fabric or canvas that cause weaknesses in it;
    , ¡The flow of turbined air is allowed to escape, avoiding the entry of water into the umbrella or umbrella; , Device for easy assembly and disassembly both in existing umbrellas or umbrellas and in new factory designs;
    5 To complement the description and in order to help a better understanding of the features of the invention, a set of figures with an illustrative and non-limiting nature is attached as an integral part of said description.
