OBJECT OF THE INVENTION [0001] As stated in the title of this specification, the following invention relates to a border protector fence system, being of special utility for the assembly thereof in the protection of border zones, with the aim of being able to quickly detect any attempt at access via the fence system. [0002] Likewise, an important aim of the invention is to permit a system to be had which is reliable and at the same time prevents any kind of accident in the event of an attempt at access. FIELD OF APPLICATION [0003] This specification describes a protector fence system, which of special utility for the assembly thereof in the protection of border zones. PRIOR ART OF THE INVENTION [0004] Conventionally, among systems used in border fences having the aim of preventing passage from one country to another, we can consider the system which consists of a pair of fences, parallel to each other, installed along the length of the zone to protect and whose fences are made up of support profiles between which is arranged a metal net. [0005] Likewise, in a first practical embodiment, the upper part of the support profiles can end in at least one inclined section, with various rows of barbed wire being provided between those inclined sections. [0006] In a second practical embodiment, the support profiles can end in two inclined sections, towards both sides, with various rows of barbed wire being able to be provided between them, while in their central upper part, between the inclined sections, which define a "V" shape in space, a spiral roll of barbed wire can be laid. [0007] In this way, it is possible to position a ladder or other similar elements on top of the barbed wire arranged between the inclined sections in which the support profiles end with the aim of being able to access the upper part of the fence and, by means of laying a protector element on top of the barbed wire, such as a simple piece of cardboard, with the aim of preventing cuts, one can overcome the fence. [0008] Equally, in relation to the internal face of the first protector fence, one or more rolls of barbed wire can be positioned, these rolls being able to take on different arrangements. [0009] The barbed wire defining the spiral roll can present different forms of blades. [0010] This configuration presents the drawback that, in addition to not being infallible, anyone who tries to "clear" the described protector fence could suffer serious accidents, mainly as a consequence of severe cuts. DESCRIPTION OF THE INVENTION [0011] The present specification describes a border protector fence system, being of special utility for the assembly thereof in the protection of border zones, in such a way that the system comprises: [0012] a first fence consisting of some profiles secured in an inclined position, ending in at least one hinged spring, among which profiles some steel stays and a metal net are arranged; [0013] a second fence consisting of some profiles secured in a vertical position, with some steel stays and a metal net being arranged among them; [0014] some profiles arranged between the first and second fence, of less height than the profiles of the first and second fence, with a diversity of intersecting steel stays being provided between the intermediate profiles and the first and second fence; [0015] means of alarm mounted in relation to the second fence, associated with the structure of the first fence and with the diversity of intersecting steel stays arranged between the first and second fence; and [0016] some ducts for a fluid mounted in relation to the second fence provided with some outlet mouths under pressure towards the zone of the intersecting stays. [0017] The profiles relative to the first fence will be secured with an inclination towards the side where access is possible, presenting an inclination of approximately 75.degree. with the ground. [0018] Likewise, in a preferred embodiment, the profiles secured in an inclined position relative to the first fence present a general cross-section in the form of a double "T", with a series of holes in its core at different heights, for the passage and positioning of the steel stays or cables, in such a way that the lattice of stays or cables between the profiles relative to the first fence stiffen the latter and prevent passage in conjunction with the metal net. [0019] Equally, the profiles secured in an inclined position relative to the first fence present a pair of hinged spring elements in their upper part, mounted in proximity and consisting of a body with a series of annular pieces for the passage of some steel stays. [0020] Moreover, a first hinged spring element, relative to the profiles constituting the first fence, is mounted at its free end with an inclination greater than that of the actual profile, while the second hinged spring element, mounted at a slightly lower position, has the same inclination as the actual profile. [0021] So, in the event of an attempt to position any support such as a ladder, in order to thereby gain access to the upper part of the first fence, the actual action of its weight on the stays or cables, arranged in the highest position and associated with the hinged spring elements, will cause them to rotate downwards, thus preventing access. [0022] From their original rest position, the hinged spring elements have a limited angle of rotation, downwards, depending on the desired angle. [0023] Moreover, the means of alarm mounted in relation to the second fence consist of at least one perimetric system defined by a diversity of stays, which cover the entire perimeter, to which an optical fibre is incorporated with an emitter and a receiver, being associated with the structure of the first fence and/or with the structure of steel stays or cables existing between the first and second fence. [0024] In this way, in a practical embodiment of the invention, the means of alarm mounted in relation to the second fence can consist of two perimetric alarm systems, a first perimetric system being defined by a diversity of stays, which cover the entire perimeter, to which is incorporated an optical fibre with an emitter and receiver, to which stays are joined a series of stays which are in turn joined to the structure of the first fence. [0025] The second means of alarm mounted in relation to the second fence will consist of a second perimetric system, defined by a diversity of stays, which cover the entire perimeter, to which is incorporated an optical fibre with an emitter and receiver, to which stays are joined a series of stays which are in turn joined to the structure of intersecting stays existing between the first and second fence.
