Description

The invention relates to renewable energy and can be used in the development of new types of wind turbines of different capacities operating in free air flows.

The closest analogue (prototype) is known - a wind and hydraulic installation with oscillating vertical blades (1), however, it is able to balance the tipping forces only in water flows due to the large lifting force of the sealed hollow blades, while its emergency design does not provide for emergency stop with simultaneous rotation of the blades in the air flow.

An object of the invention is the creation of compact, balanced overturning efforts, silent and safe wind turbines with advanced features that allow you to additionally install them on the roofs of buildings, and in the marine version - on the decks of non-self-propelled boats.

This goal is achieved by the fact that the console mounting unit with blades contained in the wind turbine and the multi-pole generator with the multiplier coaxial with it are shifted relative to the additional stationary carrier body towards the incoming air flow and placed using an intermediate bracket on the upper platform of the inclined rotary frame, rigidly connected in the lower parts with a central vertical shaft mounted on bearings in the bearing housing, which is inhibited by a worm gear connected by with a pair of bevel gears with a shaft of a reversible direct current electric motor electrically connected with a vane node for the self-orientation of the blades in the wind, located in the upper part of the central shaft.

In the casing of the rotary console near the axis of the main blade, a locking fork and a solenoid are additionally fixed, electrically connected to the emergency check switch of its power circuit, located on the upper end of the axis of attachment of the rotary console. An emergency stop of the console with blades in any range of wind speeds is carried out using an external remote contactor of the solenoid power supply circuit.

In the absence of supply voltage, the console with the blades is stopped manually - with the help of a thin long cable connected to the locking fork, connected at the bottom of the inclined frame with a tensioning rotary lever.

For uninterrupted consumption of generated electricity, the installation is equipped with technical means (electrochemical and oxygen-hydrogen) for converting and accumulating its excess part at night and during periods of strong winds, and in the ship's version, also when anchoring and using it as a mobile autonomous floating power station for power supply of coastal non-electrified settlements and other objects remote from energy resources. Placing on the deck of a non-self-propelled craft (preferably the most stable catamaran with two installations), provides him with the ability to sail for unlimited time without the consumption of hydrocarbon fuel and without sailing equipment.

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 1 is a side view of the installation with the blades deployed in the air flow.

Figure 2 is a top view of the installation with the working position of the blades (the upper platform of the inclined swing frame and the intermediate bracket are not shown).

Figure 3 is a side view of the location of the main energy nodes inside a stationary bearing body.

Figure 4 is a side view of the placement inside the casing of the rotary console of the locking fork, solenoid and staples with a cable (a) and a top view of the locking fork (c).

5 is an electrical diagram of the installation (P.U. - moving nodes circled by a dashed line).

The installation comprises a rotary console 1 with the main 3 and auxiliary 4 blades placed on its casing 2, fixed by means of a node 1 / on the vertical axis 5 and held in horizontal position by a cable extension 6 with a tension lanyard 7, and the axis 5 is connected via a multiplier 8 with a multipole generator 9, which in the proposed design solution are biased towards the incident air flow.

The installation is additionally equipped with a bearing sleeve 10 located on the axis 5 with an intermediate bracket 11 fixed on it, the base of which is connected by bolts 12 to the upper horizontal platform of the inclined support frame 13 with two cheeks 14 mounted on it, with horizontal slots for attaching a multi-pole generator 9 s to them by the multiplier 8. The frame 13 in the lower part is rigidly connected with the hollow vertical central shaft 15, on the upper end of which there is a weather vane 16 with a contact group of switches 17 and the inner m harness 17 / and lower portion of the shaft 15 placed on the thrust bearings 18 and 19 in the stationary supporting frame 20, hold down support arms 21. Inside the housing 20 the shaft 15 planted on its inhibitory worm wheel 22, articulated through a horizontal worm shaft 23 and a pair of bevel gears 24 with a shaft of a reversible direct current electric motor 25, electrically connected with vane switches 17.

A three-phase power rectifier 26, a voltage regulator 27 for internal recharging of the buffer battery 28, a power collector current collector 29, and a distribution low-current collector current collector 30 are also located inside the housing 20. An emergency flag 36 with a push-button closure 37 is located on the upper end of the axis 5 (tiltable by excess air flow) the power circuit of the solenoid 38, the rod of which is connected by means of a spring plate 39 to the locking fork 40, held by an arm 41 and connected by a return ruzyne 42 with the bracket 43. At the end of the solenoid rod 38 is attached a movable bracket 44, connected via the guide sleeve 45 with the cable 46 extended thin outputted outward from the console 1 and connected to the rotary tensioning lever 47, fixed at the bottom of the supporting frame 13.

Installation works as follows.

The installation assembled at the place of operation is located on a flat platform (mast, elevations, building roof, deck of a non-self-propelled vessel, etc.). The twin sections of the blades 3 and 4 are easily removable, so they can be fixed last on the fixed casing 2 of the console 1. When fixing the intermediate bracket 11 with bolts 12 on the upper horizontal platform of the inclined supporting frame 13, it is more preferable to shift it towards the incoming wind flow for additional compensation for dynamic overturning effects created mainly by working blades.

The vane system carries out the self-orientation of the blades in the wind and tracks the change in its direction within 360 ° as follows.

When the direction of the incoming flow changes by an angle ± α p exceeding the free play angle α 0 of the vane 16, the left or right contact group of the dual switches 17 (for example, type P2T-5) closes, and the reverse motor 25 turned on by a pair of bevel gears 24 and the worm pair 23.22 will turn the central shaft 15 in the same direction and the same angle, while the plane of the weather vane 16 will again be oriented in the air flow, and the opened switches 17 will spontaneously return to the neutral average position (figure 5) and turn off the reversing electric motor 25.

In the range of excess wind speeds, for example, more than 30 m / s, the pre-calibrated emergency flag 36 tilts down and closes the contacts 37, while the rod retracted into the coil of the solenoid 38 (Fig. 4a) presses the fork 40 simultaneously against two levers 48 and 48 / of the transverse rocker arm, planted in the center of the axis of the main dual blade 3 and when it is in the extreme right II or left III positions (figure 2), i.e. in the process of turning it with the air flow to start the reciprocating movement in the opposite direction, at the moment of coincidence of the plane with the axis of the console 1, the grooves 49 of the plug 40 will close with the levers 48 and 48 / and the axis of the blade 3 will be locked, as well as the axis of the auxiliary blade 4 connected with it At the same time, both blades, which are already in the vane mode, will turn under the pressure of the wind to position I and for the entire storm (or storm) time will be kept deployed in the air flow, including when its direction changes. After weakening the wind to operating values, for example, below 30 m / s, the flag 36 rises, the weakened solenoid rod with the help of a spring plate 39 and a return spring 42 returns to its original position, the fork 40 to the upper open position (Fig. 4a), and blades - in the working (figure 2). The presence of the console with the blades in the extreme positions does not significantly affect the overall balancing of the installation.

Before carrying out scheduled preventive or repair work with the power supply turned off, the main blade 3 is manually locked with the fork 40 using the bracket 44, which is additionally mounted on the end of the stem 44 and connected via a thin extended cable 46 of the pivoting tension lever 47 by turning it to the lower position. After completion of work, the lever 47 is necessarily transferred to the upper position, while the fork 40 opens with the levers 48 and 48 / , and the blades spontaneously return to the working position.

In the marine version, especially when using the unit as an autonomous power station, it is additionally supplied with technical means of electrochemical, oxygen-hydrogen or other accumulation of generated excess electricity for uninterrupted supply of external and internal consumers to it.
