RU2546373C1 - Oscillating console with rotary flaps of main blade of wind and hydroelectric power plant - Google Patents

Abstract

FIELD: power industry.

SUBSTANCE: at end faces of the top and bottom sections of the main blade from the side of the running flow the rotary flaps of a flowline shape are placed, which are withheld within the limiting angles by the springing forks and returnable springs with adjustable tension are located in addition on trailer pins. Hollow sections of the main blade are in addition strengthened inside by corrugated stiffening ribs, especially in places of contact with the damping overlays of springing forks. The invention promotes creation of new types of environmentally friendly and low-noise wind- and submersible hydroelectric power plants.

EFFECT: improvement of efficiency of rotation of blades in extreme left and right positions, improvement of spontaneous start of the console after its stop during a storm or scheduled maintenance.

Description

The invention relates to renewable energy and can be used to create new non-rotating kinetic energy converters for wind and hydraulic installations operating in free air or water flows.

Known rotary console of a wind and hydraulic installation with oscillating vertical blades (1), containing kinematically coupled twin main and auxiliary blades. However, such a constructive solution implements the transmission of torques with significant losses in the extreme left and right positions of the main blade, especially at small angles of attack to the incoming flow.

An object of the invention is the creation of more efficient non-rotating technical means of converting the kinetic energy of air or water flows with a more uniform torque on the shaft of a multipolar generator, as well as improving the spontaneous start of the console after it stops during a storm or during preventive maintenance.

This goal is achieved in that at the ends of the upper and lower sections of the main blade on the side of the incoming flow, streamlined flap flaps are additionally placed on the end pins, held within the limiting angles by spring forks and return springs with adjustable tension.

The planes of the rotary flaps as well as the main and auxiliary blades have a simple symmetrical streamlined shape, which generally reduces their cost and improves manufacturability.

From the patent and scientific and technical information, the author does not know the sources containing information about similar technical solutions having similar features with the claimed solution.

The invention is illustrated by schematic images, where:

Figure 3 - Fragment of the main blade with a flap:

The console 1 contains kinematically connected main 2 and auxiliary 3 twin blades placed on an airtight casing 4. At the ends of each section of the main blade 1, a rotary flap 6 is additionally placed on two end pins 5, on which two spring forks 7 with damping plates 8 and are fixed stand 9, connected by means of a return spring 10 with a threaded axis 11, connected by means of a figured nut 12 with an angular bracket 13, mounted on a carrier plate 14.

Inside each of the hollow sections of the main blade 2 are placed reinforcing their strength corrugated stiffeners 15, especially in places of contact with the damping pads 8 spring forks 7.

The console works as follows.

If, for example, initially the axis of the console 1 was in the middle position, coinciding with the direction of flow, and the plane of the main blade in the left, then they, together with the auxiliary blade 3, will move to the left (figure 1). With the continuation of the motion of the blade 2 to the leftmost position, the angle of attack of its plane relative to the flow will be proportionally reduced and at the conditional point A _z ′ (in the vertical plane mm) it will be equal to zero. At the same time, the auxiliary blade 3 under continued pressure on its plane of the incoming flow will continue to turn the console 1 to the left, while the main blade 2, going into the negative angle α _l ^- , will begin to turn around its axis in the opposite direction, and the flap 6 - an additional turn to a fixed angle α _s ^- and will create additional effort for the rotation of the working blade 2 to the full angle β _l ^- and simultaneously with it the rotation of the auxiliary blade 3 to a larger angle (the new relative position of both blades is shown by a dashed line). Thus, in the range A ₃ -A _s ′, maximum force is created to turn the console 1 to the right. All subsequent processes on the right side in the range A ₁ ′ -A ₁ will be identical. The full working angle of the turn of the console 1 in each direction is α _to ⁺ + α _to ^- and in practice is in the range of 50-70 degrees.

The necessary working tension of the return spring 10 with a constant shoulder t of the arm of the rack 9 is carried out by turning the adjusting curly nut 12.
