Полезная модель относится к ветроэнергетике, а именно к ветродвигателям роторного типа с вертикальным валом вращения и может быть использована в электромашиностроении.Задача, на решение которой направлена заявленная модель, заключается в создании модульной мачты, прочной по своей конструкции и, кроме того, удобной для ремонта, монтажа, обслуживания, а также транспортировки.Техническое решение заключается в создании мачты модульного типа, где мачта поделена на несколько модулей: модуль с генератором и модули с лопастями. При сборке модулей образуется внешний каркас, который несет основную нагрузку.Техническим результатом является создание конструкции мачты, совмещающей в себе требования к прочности за счет внешнего каркаса, а также удобства для ремонта, обслуживания и транспортировки, с возможностью изменения мощности генератора, за счет того, что мачта состоит из модулей.Мачта модульного типа состоит минимум из двух модулей, соединенных между собой. Основанием мачты служит модуль генератора. Модуль генератора крепится на грунт, бетонное основание или крышу здания. На модуль генератора сверху устанавливается модуль ветроуловителя (модуль с лопастями). Монтаж происходит таким образом, что выходной вал ветроуловителя соединяется с помощью муфты для передачи момента. Крепление силовых рам модулей болтовое. При необходимости можно поставить еще один или несколько модулей с лопастями, которые соединяются между собой аналогичным образом.

The WS2 is made of a flexible rust resistant galvanized sheet metal, or other material that can be strong and flexible, that is preformed and bent to it permanent shape, which is a rectangular shape with four sides, one of which has a flap which has an outward fold and an adjacent side which has an inward fold. This allows user to hook together the two open sides. The flap and adjacent side have opposite folds that are designed to lock together making WS2 a secure one piece unit. The WS2 can be flexed open and placed around a wooden post, then to, on its own, snaps shut protecting the post from weed eater damage. There is no folding or unfolding needed. No screws or nails are needed to hold WS2 in place, because of WS2 self locking folds.
