Wind turbine and tower or tower segment and door frame therefor
View Patent ↗The invention relates to a tower or a tower segment of a wind turbine, having a door for entering the inside of the tower, comprising a door frame, which has a door opening that is preferably closed by a door leaf. The Invention further relates to a door frame for a door of a tower of a wind turbine, said frame having a door opening that is preferably closed by a door leaf, and to a wind turbine having a tower, a door provided for entering the inside of the tower, and a staircase leading to the door on the outside of the tower, preferably of a tower described above. The underlying object of the invention is to provide an air passage opening in at least one advantageous location. This object is achieved according to the invention in that the door frame has at least one air passage opening, particularly an air inlet opening.
1. A tower of a wind power installation, comprising:
an outer wall surrounding an interior of the tower,
a transformer for installing in the interior of the tower,
said outer wall comprising a reversibly detachable door frame comprising an outer contour, a door opening and a door leaf, wherein the door opening is closed with the door leaf,
at least one air passage intake arranged in the door frame below the door leaf, wherein the at least one air passage intake comprises a first ventilator that transports ambient air from an exterior of the tower to the interior of the tower for cooling the transformer,
at least one air discharge opening arranged in the door frame above the door leaf, wherein the at least one air discharge opening comprises a second ventilator that transports the air from the interior of the tower to the ambient air at the exterior of the tower,
wherein the transformer is housed in a housing and the ambient air that is drawn in through the at least one air passage intake is conducted through an air conduit of air transformer housing underneath the transformer, and wherein the transformer housing has an upper area in which heated air is trapped by a hood and conducted through a conduit to the air discharge opening,
wherein the outer contour of the door frame forms an area in the outer wall, and wherein the area in the wall is larger than a cross-sectional area of the transformer, and wherein the cross-sectional area of the transformer is larger than the door opening, and
a horizontal loading beam attached to a lifting appliance, wherein the transformer is temporarily attachable to the horizontal loading beam and the transformer is thereby transportable,
wherein the transformer is transported along the horizontal loading beam through the area in the outer wall into and out of the interior of the tower only when the door frame is detached and removed from the door opening.
2. The tower according to claim 1 , characterized in that the door frame has a substantially oval outside contour and that the door opening is substantially rectangular.
3. The tower according to claim 1 , characterized in that the door frame has a substantially oval outside contour and that the door opening is substantially rectangular.
4. A reversibly detachable door frame for a door of a tower of a wind power installation closed with a door leaf,
wherein the tower comprises an outer wall surrounding an interior of the tower, and a transformer for installing in the interior of the tower,
wherein the reversibly detachable door frame is arranged in the outer wall, and comprises an outer contour, a door opening and a door leaf, wherein the door opening is closed with the door leaf,
at least one air passage intake arranged in the door frame below the door leaf, wherein the at least one air passage intake comprises a first ventilator that transports ambient air from an exterior of the tower to the interior of the tower for cooling the transformer,
at least one air discharge opening arranged in the door frame above the door leaf, wherein the at least one air discharge opening comprises a second ventilator that transports the air from the interior of the tower to the ambient air at the exterior of the tower, and wherein the at least one discharge opening is arranged on a side of the tower facing away from the at least one air intake opening,
and wherein the air is trapped by a hood and discharged to the outside via an air conduit,
wherein the outer contour of the door frame forms an area in the outer wall, and wherein the area in the wall is larger than a cross-sectional area of the transformer, and wherein the cross-sectional area of the transformer is larger than the door opening, and
a horizontal loading beam attached to a lifting appliance, wherein the transformer is temporarily attachable to the horizontal loading beam and the transformer is thereby transportable,
wherein the transformer is transported along the horizontal loading beam through the area in the outer wall into and out of the interior of the tower only when the door frame is detached and removed from the door opening.
5. The door frame according to claim 4 , characterized in that the door frame has a substantially oval outer contour and that the door opening is substantially rectangular.
6. The door frame according to claim 4 , characterized in that the door frame has a substantially oval outer contour and that the door opening is substantially rectangular.
