SELF-CONTAINED POWER-GENERATING DEVICE Russian patent published in 2007 - IPC F03G7/04 

FIELD: mechanical engineering.

SUBSTANCE: invention is designed for converting energy of air flow appearing in vertical pipe opened from end faces into electric energy. Proposed self-contained power-generating device contains power unit, system creating air flow through power unit and output voltage stabilizing and control unit. Power unit is made in form of cylindrical hollow vertically installed housing with stator of electric generator placed inside. Said stator accommodates multiple-stage propeller-type turbine installed ion vertical shaft with rotor of electric generator enclosing the turbine and made of magnetic material or provided with filed windings. Vertical shaft of turbine is installed on upper and lower magnetic supports each being formed of magnetic cone installed in conical space of magnetic base. Magnetic base of upper magnetic support is installed higher than rotor. Magnetic base of lower magnetic support is arranged lower than rotor, and cone and conical space of base are pointed to each other by like magnetic poles. System to deliver air through power unit consists of two parts, lower one on which power unit is arranged and upper one connected to power unit from top. Lower part is made in form of cylindrical shell and is designed to create air flow at inlet of power unit, and upper part is made in form of tube of rigid or soft airtight material. Upper part made of soft material is provided with braces and inner bridges to fix position of upper part relative to power unit and with spaces formed in wall of upper part made of gas tight material and filled with gas lighter-than-air and communicating with reservoir through valve for delivery of gas lighter-than-air into said spaces.

EFFECT: ecologically clean generation of electric energy of different power.
