Description

Wind power plant with exhaust air outflow amplifier

The utility model relates to the field of wind energy, namely, devices for generating electricity.

A device for a wind power installation is known (patent RU 74670, publication date July 10, 2008). The utility model contains a wind power installation containing a support on the foundation, on the top of which a block frame is rigidly mounted with twelve inlet nozzles on its vertical surface for air inlet air inlet and with a diffuser for air outlet on its upper cover mounted in the block frame a wind turbine rigidly connected to a vertical shaft, which has a kinematic connection with the electric generator by means of a hydraulic brake system with a flywheel, of a lower gear, which made in the form of the rear axle of the car, the body of which is rigidly connected to the foundation, and the coupling, while the vertical shaft is mounted in bearings with the possibility of rotation, and the support is made sectional. This device is accepted as the closest analogue.

However, this power plant is characterized by insufficient functionality. The main disadvantage of the analogue is the lack of efficiency.

The task to which the utility model is directed is to increase the efficiency of a power plant.

The technical result is aimed at creating an inexpensive, easy to manufacture and operate wind energy device for converting the kinetic energy of the wind into mechanical energy of rotation of the wind wheel with further conversion to electrical energy.

The specified technical result is achieved by means of a power plant with an amplifier for outflow of exhaust air containing a support mounted on a reinforced concrete foundation, and the vertical shaft of the wind wheel has a kinematic connection with the electric generator, while the support is fixed through threaded joints to anchor bolts; a rotary support device is attached to the upper part of the support by means of a threaded connection and bearings to move the movable wind turbine housing, and an exhaust air outflow amplifier is attached through the threaded connection to the upper part of the movable wind turbine housing; from the windless side of the wind turbine through the threaded connection, a vane-type stabilizer is attached, an inlet nozzle is installed on the windy side; shear type pressure stabilizer inside the wind turbine.

In FIG. 1 shows a general view of a wind power plant; FIG. 2 shows a top view.

The essence of the utility model is as follows.

Wind power installation with an exhaust air outflow amplifier ”, contains a support (13) mounted on a reinforced concrete foundation (14), which is fixed through a threaded connection. A rotary support device (8) is fastened to the upper part of the support (13) by means of a threaded connection and bearings (7) for moving the movable housing (3) of the wind turbine. An exhaust air amplifier (5) is attached to the upper part of the movable casing (3) of the wind wheel through a threaded connection. The vertical shaft (2) of the wind wheel (1) has a kinematic connection with the electric generator (11) through a bearing system (7). At the base of the earth's surface, a car disk (9) with a hydraulic braking system is attached to the system of vertical working shafts installed in the bearings (7) and the threaded connection to stop the rotation of the vertical shaft (2), the gearbox (10) through the shaft (2) and the coupling ( 12), which is installed in the bearings (7), is attached to the car disk (9) with a hydraulic braking and stopping system for the vertical shaft (2), the coupling (12) couples the gearbox (10) rigidly to the electric generator (11). On the windless side of the wind turbine (3) through a threaded connection, a vane type stabilizer (6) is attached, an inlet nozzle (4) is installed on the wind side, and there is a slide type pressure stabilizer inside the wind turbine (not shown in the drawing).

The first essential sign sufficient to achieve the above technical result is the presence of working bodies of an exhaust air outflow amplifier (5) and a wind engine consisting of: a wind wheel (1), which has a kinematic connection with an electric generator (11), a vane type stabilizer (6 ), movable housing (3), inlet nozzle (4).

The second essential sign sufficient to achieve the above technical result is the presence of working bodies: a pressure stabilizer (slide type) inside the wind engine, the action of which in the case of strong and gusty wind gusts allows maintaining the operation of the wind turbine in a mode close to the maximum power mode. Also, the presence of such a device will significantly reduce operating costs and increase the life of the wind power plant.

The device operates as follows:

The air flow acts on the stabilizer of the vane type (6), as a result of this action, the movable body of the wind wheel (3) is rotated, since it is mounted on the support-rotary device (8), which fixes the position of the inlet nozzle (4). The air flow passing through the inlet nozzle (4) is compressed due to its design feature in proportion to the ratio of the outer inlet area and the inner area; all this leads to an increase in aerodynamic force and an increase in the force acting on the blade elements of the wind wheel (1) of the wind engine, which leads to the torque of the wind wheel (1) of the wind engine, consisting of a vertical shaft of the wind wheel (2) and attached to it blade elements, which transmits a torque via a kinematic connection to an electric generator (11). The air flow, when interacting with the blade elements of the wind wheel (1), is inhibited, which leads to a decrease in the aerodynamic velocity of the flow and a drop in kinetic energy.

The exhaust air outflow amplifier (5) with the lower diameter corresponds to the upper diameter of the movable housing of the wind turbine, while the upper diameter of the exhaust duct (5) is 30% less, which contributes to an increase in the speed of the air flow inside the wind turbine.

The exhaust air outflow amplifier (5) provides an efficient outflow of exhaust air from the wind engine.

With the help of the gearbox (10), the speeds of the working shaft are increased and its output shaft is rigidly connected to the electric generator (11) with the help of a coupling (12). The air flow, interacting with the blade elements of the wind wheel (1), swirls and brakes, the presence of an exhaust air outflow amplifier (5) in this design provides an effective outflow of exhaust air from the wind turbine, which reduces the loss of air flow velocity inside the wind turbine by up to 70%.

The proposed design of a device for converting kinetic energy of the wind into mechanical energy of rotation of the wind wheel with further conversion into electrical energy is characterized by high manufacturability, the absence of expensive materials and minimal need for machining of materials. A power plant with an exhaust air outflow amplifier has a relatively simple design, primarily because its production does not require high-tech equipment. The main parts of wind power plants are a weather vane stabilizer (6), an electric generator (11), a car disc with a hydraulic braking system (9), for stopping a vertical shaft (2) of a wind wheel (1), an exhaust air outflow amplifier (5), a movable housing wind turbine (3), inlet nozzle (4), shear-type pressure stabilizer inside the wind turbine.
