Description

The invention relates to wind energy and can be used to drive electric generators, hydraulic pumps and other mechanisms of the payload of small autonomous energy in various sectors of the economy.

Known wind power installation with a vertical axis, containing a horizontal base and a conical dome, which is installed above the horizontal base on the uprights. In the upper central hole of the dome, an impeller with a vertical shaft is mounted on a conical deflector to drive consumer mechanisms. The horizontal base and the dome form an annular opening for air inlet for the blades of a wind wheel (see US Patent No. 4017205, F 03 D 3/04, 1977).

The disadvantages of this installation are the insufficiently efficient conversion of the incoming wind flow energy, the poor use of local natural heat fluxes and the insufficient reliability of the installation of the wind wheel with large diametrical dimensions.

Also known is the design of a wind power installation comprising a tower casing with a wind wheel and inlet channels with air dampers, the tower casing consists of a lower confuser, middle cylindrical and upper diffuser parts, a wind wheel is installed horizontally in the cylindrical part of the tower casing on a vertical shaft, the unit is equipped with an actuating mechanism containing a shaft with a common central rotary link kinematically connected with the dampers and the vertical shaft of the wind wheel (see AS SU No. 1134771, F 03 D 3/04, 09.04.81. Bull. No. 2, 1985).

The disadvantages of such wind power plants are low specific power, large uneven operation of the wind wheel, lack of efficient use of internal heating of additional gas-air flows and insufficient reliability of the installation of the wind wheel with large diametrical dimensions.

The objective of the present invention is to increase specific power, improve control of the operation of the wind wheel and its reliability. The problem is solved in such a way that in a wind and thermal power plant containing a tower case with inlet channels with air dampers in the lower confuser part, the middle cylindrical part and the upper diffuser with a deflector, a wind wheel located in the cylindrical part of the tower on a vertical shaft, a servo mechanism with a common central the rotary link kinematically connected with the shutters, the input channels are tangentially directed and inclined to the vertical axis of the tower body, inside the lower onfuzornoy portion coaxially therewith, an additional convergent channel, and wind wheel arranged movable supports resting on the monorail.

The drawing shows a General view of a wind thermal power plant with sections aa and bb.

The wind thermal power plant comprises a tower casing 1, consisting of a lower confuser part 2 with tangentially directed inlet channels with air dampers 3 inclined to its vertical axis, a middle cylindrical part 4 with a monorail 5, an upper diffuser part 6 with a deflector 7, a wind wheel 8 mounted on a vertical shaft 9 and additionally supported by movable bearings on a monorail 5, an additional confuser channel 10, coaxially located inside the lower confuser part 2 of the tower housing 1. The shaft 9 is connected with Ithel energy 11. At the bottom of the tower 12, the heat sources are arranged.

Installation works as follows. Inlet tangentially directed channels with air dampers 3 inclined to the vertical axis of the tower 1 perceive natural air currents and pulsations of various directions and transform them into an organized internal vortex upward flow, which creates an additional vacuum in the center vertically of the entire tower body, into the zone of which they come from the central the output part of the additional confuser channel 10 heated by various sources 12 additional gas-air flows that increase the heat pressure and ultiruyuschee effect on the wind wheel propeller 8. The movable support 8 is further based on the monorail 5, mounted in the middle of the cylindrical portion 4 of the body 1 of the tower.

The efficiency of such power plants in the Far North and arid regions will be almost 10 times higher than diesel ones.
