Hatch arrangement for closing an opening in a floor of a wind turbine and a wind turbine

A hatch arrangement with at least one slidable hatch for closing an opening in a floor of a wind turbine, the hatch arrangement comprising:

• a first guiding device which is fixedly mountable to the floor;
• a second guiding device which is pivotably mountable to the floor;
• and
• a first coupling means to guide the at least one slidable hatch along a first guidance path in the first guiding device and a second coupling means to couple the at least one slidable hatch at least pivotably to the second guiding device;
• wherein the at least one slidable hatch is coupled to the first guiding device at a first position and to the second guiding device at a second position, the first position and the second position being located along a longitudinal direction of the at least one slidable hatch and spaced apart from each other;
• wherein a movement of the at least one slidable hatch from a closed position along the first guidance path results in a pivoting movement of the second guiding device and in a movement of the at least one slidable hatch to an open position and vice versa;
• wherein the at least one slidable hatch comprises a hatch opening for a wire in the closed position.
