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.
