Abstract

FIELD: engines and pumps.

SUBSTANCE: invention relates to wind power engineering. Proposed windmill comprises air wing, generator, coupling, brake, reduction gear, pulley block, coils and auxiliary weights. Pulley block weight approaching top position, first coil is de-energised and first auxiliary weight, moving down, unlocks coupling and brakes the drum. Pulley block weight approaching bottom position, second contact closed first contact for first coil to pull core in and throw in the coupling that couples reduction gear, drum and pulley block with generator shaft so that pulley block lefts the weight. In no-wind condition, second coil is de-energized for second auxiliary weight to lift first auxiliary weight so that drum brake is released and coupling is engaged to generate electric current due to pulley block weight gravity travel.

EFFECT: continuous operation irrespective of wind availability.

Description

The invention relates to wind energy.

The prior art scheme for controlling an accumulator device in wind energy is such that the accumulator device is connected to a wind turbine to store energy during periods of wind, disconnect when the load is filled with energy, and reconnect when there is no wind (see application DE 102006003897 A1, F03D 9 / 02, 08.08.2007, 13 p. (1)).

The technical result of the claimed invention is to ensure the continuity of the operation of the wind turbine regardless of the presence of wind.

The technical result is achieved by the fact that the wind turbine contains a wind turbine, generator, clutch, brake, gearbox, drum, chain hoist, contacts, coils and auxiliary loads. When approaching the tackle load to the upper position, the first coil is de-energized and the first auxiliary load, moving down, opens the clutch and brakes the drum with a brake. When the pulley gear approaches the lower position, the second contact closes the first contact and the first coil retracts the core and includes a coupling connecting the gearbox, drum and pulley block to the generator shaft and the windmill so that the pulley lifts the pulley. In the absence of wind, the second coil is de-energized and the second auxiliary load, lifting the first auxiliary load, brakes the drum and turns on the clutch to generate current from the gravitational movement of the pulley load by the generator.

The drawing shows a wind turbine in accordance with the claimed invention.

Windmill operates as follows.

When approaching the upper position of the pulley load G, the contacts E ₁ and E _{2 are} open, the first coil And _{1 is} de-energized, the first auxiliary load G ₁ , moving downward, opens clutch M and brakes the drum 1 with brake 2, disconnecting the pulley 3 from the system. In this case, the wind generates current through the wind turbine and the generator shaft 4 in the generator 4.

When the load G of the chain hoist approaches the lower position, the second contact B ₂ closes the first contact B ₁ , and the first coil And ₁ pulls the core and turns on the synchronous clutch M, connecting the gear 5, the drum and the chain block with the generator shaft and the wind turbine 6 so that the load hoists G.

At this time, in the presence of wind, the generator generates energy, holding the core of the second coil And ₂ in the upper position.

There is a process of energy production by the generator from the wind and the lifting of the load G of the tackle (accumulation of potential energy).

When the load G of the chain hoist is raised to the upper position, the first contact B _{1 is} open, the first auxiliary load G _{1 has} lowered and, having opened the clutch M, has weakened the drum and has braked.

At this moment, the second coil And ₂ holds the second auxiliary load G ₂ , the current goes from the generator to the network, and through the first coil And _{1 the} chain hoist is inhibited and disconnected by the coupling M from the generator.

Calmness has arrived - there is no wind.

The second coil And _{2 was} de-energized, and the second auxiliary load G ₂ , lifting the first auxiliary load G ₁ , disengages the drum while turning on the coupling M, connecting the gearbox to the drum, pulley and generator, and the generator generates current from the gravitational movement of the load G of the pulley.

When the load G of the tackle has reached a low position, when the wind appears, the generator simultaneously starts to wind. In this case, the generator will be scrolled by the wind and the chain hoist will return to rise, since the first contact B ₁ is closed, the core of the first coil And ₁ is retracted, the clutch M is turned on and the drum is released, allowing you to supplement the energy supply by lifting the load G of the chain hoist.

Thus, the wind turbine operates continuously regardless of the presence of wind in automatic mode.
