Arrangement with a nacelle and with an instrument
View Patent ↗An arrangement with a nacelle and with at least one instrument of a wind turbine is disclosed. The instrument is connected with a rod. A channel penetrates the wall of the nacelle. The channel interacts with the rod in a way that the rod and its assigned instrument are moved through the channel between a first and a second position. The instrument is positioned inside the nacelle at the first position for installation and/or service purposes, while the instrument is positioned outside the nacelle at the second position for operation purposes of the instrument.
1. Arrangement with a nacelle and with at least one instrument of a wind turbine,
an instrument connected with a rod; and
a nacelle comprising a channel which penetrates a wall of the nacelle, the channel interacts with the rod such that the rod and the connected instrument are moved through the channel between a first and a second position,
wherein when the instrument is positioned inside the nacelle at the first position for installation and/or service purposes, and
wherein the instrument is positioned outside the nacelle at the second position for operation purposes of the instrument.
2. The arrangement according to claim 1 , wherein the wall penetrated by the channel is on top of the nacelle and the channel penetrates the top such that a longitudinal axis of the rod is vertical.
3. The arrangement according to claim 1 , wherein the channel comprises a larger diameter then a diameter of the rod, thus the rod is guided inside the channel together with the connected instrument.
4. The arrangement according to claim 1 , wherein the rod contains a telescope mechanism.
5. The arrangement according to claim 1 , wherein the rod is hollow, and electrical wires are located and guided into the hollow rod.
6. The arrangement according to claim 1 ,
wherein the channel contains an integrated flange, which is used to interact with an O-ring sealing, and
wherein the rod contains an integrated flange, used to interact with the O-ring sealing for a substantially tight sealing against water, air or salt.
7. The arrangement according to claim 1 , wherein the instrument is constructed to measure environmental parameters or where the instrument contains wind wanes, an anemometer or an aviation light.
8. The arrangement according to claim 1 , wherein the instrument is includes wind wanes.
9. The arrangement according to claim 1 , wherein the instrument is includes an anemometer.
10. The arrangement according to claim 1 , wherein the instrument is includes an aviation light.
