Abstract

Ανεμογεννήτρια με τηλεσκοπικά πτυσσόμενο άξονα (1) και πτερύγια (2), με μηχανισμό ανάπτυξης σύμπτυξης των πτερυγίων (2) κατά το μήκος, ύψος και ή πλάτος τους ώστε να αυξομειώνεται η επιφάνεια που προβάλλει αντίσταση στον άνεμο αναλόγως των συνθηκών πνεόντων ανέμων και μηχανισμό με τον οποίο τα πτερύγια (2) αναπτύσσονται σε ορισμένο μήκος τόξου (10a) ενός εκάστου κύκλου περιστροφής της διατάξεως πτερυγίων και συμπτύσσονται στο υπόλοιπο μήκος τόξου του κύκλου περιστροφής ελαχιστοποιώντας την αντίσταση στο παραγωγικά αρνητικό μέρος του κύκλου. Στην ανάπτυξη του τηλεσκοπικού άξονα (1) ή και των πτερυγίων (2) χρησιμοποιείται βαρούλκο (37) με τύμπανο δύο μερών (37a, 37b) στα οποία τυλίγεται ενιαίο σχοινί (38) διερχόμενο από διαδοχικές τροχαλίες (41) διασύνδεσης των τηλεσκοπικά αναπτυσσόμενων ήσυμπτυσσόμενων τμημάτων. Ο άξονας (1) είναι δυνατό όταν συμπτύσσεται να βυθίζεται εντός υπόγειου φρέατος (7) με νερό για την εξαφάνιση της ανεμογεννήτριας όταν δεν χρησιμοποιείται και την ελαχιστοποίηση λόγω της άνωσης του βάρους της υπερκατασκευής.
