A system for installing on a tower of a wind turbine at least one moving objects monitoring device and/or at least one moving objects collision prevention device, the system comprising:
- a mounting base of the moving objects monitoring device and/or the moving objects collision prevention device on the tower of the wind turbine, wherein the mounting base is adapted to be mounted on the tower of the wind turbine,
- wherein the system is characterized in that the mounting base comprises a flat surface in a shape of a quadrilateral and at least one pair of opposite walls, wherein each wall of the pair of opposite walls extends perpendicularly to the flat surface along each of two opposite sides of the flat surface,
- and in that the system further comprises:
- a box for installing the moving objects monitoring device and/or the moving objects collision prevention device, wherein the box comprises a flat base in a shape of a quadrilateral and four sides extending perpendicularly to the flat base and circumferentially thereto, wherein a pair of opposite sides of the box and a pair of opposite walls of the mounting base are adapted to be connected to each other so as to form a closed space inside the box between the flat base of the box, the flat surface of the mounting base and the four sides of the box, wherein the flat base of the box comprises at least one opening of such dimensions that from the at least one opening passes through and protrudes therefrom the part of the moving objects monitoring device and/or the part of the moving objects collision prevention device necessary to be located outside the box in order to perform monitoring of moving objects or in order to prevent collision of moving objects with the tower of the wind turbine;
- and
- at least one supporting base for the moving objects monitoring device and/or the moving objects collision prevention device adapted to support the moving objects monitoring device and the moving objects collision prevention device, wherein the at least one supporting base and the flat base of the box are adapted to be connected to each other in the region of the flat base of the box where the at least one opening is located such that said devices are fixed on the flat base of the box in such manner that only the part of said devices necessary to be located outside the box in order to perform the monitoring of moving objects or in order to prevent the collision of moving objects with the tower of the wind turbine protrudes from the opening whilst the rest part of said devices is enclosed within said closed space inside the box, wherein the mounting base is adapted to be mounted on the tower of the wind turbine by means of at least one elongated fastening means having two ends and an adequate length for surrounding a perimeter of the tower of the wind turbine at a mounting height of the system such that after having surrounded the perimeter of the tower, the two ends are adapted to be connected to each other in order to achieve the fastening of the mounting base on the tower, wherein each of the two opposite walls of the mounting base comprises at least one hole so that the at least one elongated fastening means passes through the at least one hole of each of the two opposite walls traversing a front part of the flat surface of the mounting base from the one wall to the other wall of the mounting base, so that after connecting the two ends of the at least one elongated fastening means the mounting base is mounted on the tower of the wind turbine with an entire rear part of the flat surface of the mounting base being in contact with the wall of the tower, and wherein each of the two opposite sides of the box comprises at least one hole located at such a point of each of the two opposite sides so as to overlap with the corresponding at least one hole of each of the two opposite walls of the mounting base after the connection of the two opposite sides of the box with the two opposite walls of the mounting base, so that the at least one elongated fastening means passes simultaneously from the at least one hole of each of the two opposite sides of the box and from the at least one hole of each of the two opposite walls of the mounting base traversing the front part of the flat surface of the mounting base from the one wall to the other wall of the mounting base.
