METHOD FOR MOUNTING A TOWER SUPPORT

Nº publicación: WO2016076683A1 19/05/2016

Solicitante:
SHILIKBAYEV SERIK KADYROVICH [KZ]

Resumen de: WO2016076683A1

The method is intended for mounting a tower support, the upper part of which has elements of a wind-power station, antenna systems or other equipment accommodated thereon. When the method is being carried out, the height at which the tower support with equipment is disposed is increased by means of the combined use of two rims, namely a main rim and an auxiliary rim, which are mutually perpendicularly arranged in such a way that said rims can turn. The tower support with the equipment is accommodated on the upper part of the main rim. On the base of each rim, a lever mechanism with one long arm and two fulcra is provided, permitting a reduction in the forces required. The auxiliary rim is turned by means of a lifting-tractive mechanism, and the main rim, along with the tower support, is turned using the auxiliary rim, which is used as a vertical block. As a result of the fact that each rim is able to turn smoothly in both directions, it is possible to carry out not only initial assembly, but also periodic renovation of the entire structure on the ground, in an accessible area. The method makes it possible to increase the efficiency of using equipment mounted on a tower support.

METHOD FOR RADIATION PROTECTION OF BIOSPHERE

Nº publicación: WO2016074687A1 19/05/2016

Solicitantes:
BARSUKOVA MARIA GENNADYEVNA [RU]
BARSUKOV GENNADY EVGENYEVICH [RU]

Resumen de: WO2016074687A1

The invention relates to means for protecting the biosphere against the spread of ionizing and toxic substances. A method for radiation protection of the biosphere includes blocking airborne forms of particles and aerosols contained in emergency discharges by means of stimulating coagulation and sedimentation processes for particles and aerosols in flows of air masses. Flows of air masses are directed, by means of wind energy installations, toward a flame front of an emergency discharge flare stack. The wind energy installations are disposed on tall towers surrounding an industrial site. The distance between neighboring wind energy installations is determined on the basis of the mutual overlap of flanking airflow fields. A flare stack is kept from circumventing an oncoming flow, from above, by pumping descending airflows from tethered high-position wind energy installations operating in a ventilation mode. A gas/aerosol flare stack flow, which is blocked from three sides, is sucked into receiving windows of a pneumatic storage unit and is pumped into gas holding tanks. Gas/aerosol ventilation mixtures are released from the gas holding tanks onto a turbine. An additional source of electric energy is produced. The invention allows for retaining and rendering harmless a maximum volume of active gases of ionizing toxicants.
