Description

Wind turbine: for converting wind energy into electrical energy; i in horizontal and vertical design.

State of the art

Today, wind turbines are essentially manufactured and used as multi-blade, mainly as 3-blade rotors, which are mounted on high masts.

The efficiency in relation to the wind blade area exposed to the wind is very low.

The air flow must slide off the wind blades and can therefore only be used to a small extent for propulsion. Due to the size and centrifugal force of the rotating wind blades, the high tower must be very stable and therefore a correspondingly large foundation is required. If several turbines are located next to each other, for example on the North and Baltic Sea coasts, the landscape is changed significantly.

problem

The invention specified in claim 1 is based on the problem of creating a wind turbine with greater efficiency and versatile application possibilities.

It should be more economical, smaller, more landscape-friendly and quieter.

This problem is solved by the features listed in claims 1-4 (if applicable, citation of the features verbatim).

1.1 Wind turbines for large and multiple systems have wheel disks 0 larger than 0 2 meters and relatively small wheel disk spacing, approximately 2 meters. They are referred to below as wind turbines.

1.2 The roof is attached to 16 supports, the supports are inserted into the swivel device. The wind turbine shafts rotate in two ball bearings each, the bearing support plates are attached to the two middle supports.

1.3 The individual windbreaks are pushed over the horizontal outriggers on the support frame with angle rails attached to them (4 pieces) and anchored in the appropriate place. The angle rails can be seen on page 2 Fig. 3.

3.2 To protect the wind turbine system from destruction or overloading by storm winds, about 80% of the strongly curved wind guide should be tilted (opened). This section is suspended on hinges and is pressed onto the rubber buffers by 2 torsion springs.

3.3 If the wind speed exceeds 25 m/sec, the spring force is overcome, the wind guide opens, the wind turbine is slowed down, and the air can flow past the opposing windbreak.

4.1 The double-acting wind turbine bearing is pressed into the bearing angle. This bearing also absorbs the lateral pressure that occurs when cornering.

4.2 The wind troughs are inserted into the slots in the outer area of the wheel discs (4) and, after the wheel discs are anchored, form a stable wind turbine on the shaft.

Section G-H shows the cross-section of the wheel disc. This part, in conjunction with the segment (see sheet 5 Fig. 10), is particularly suitable for wheel discs 0 50 cm - 100 cm, and can be manufactured using die casting or plastic injection molding.

6.1 When installing the wind turbine in the vehicle, wheel disks 0 smaller than 0 50 cm are used. The wheel disk spacing is relatively large, as are the speeds "between 100 - 2000 rpm", which is why the wind turbine is referred to below as a wind turbine when used in a vehicle.

6.2 The slightly smaller wind turbine installed under the vehicle roof has the greatest efficiency due to the large wind deflector (windshield).

6.3 The W-turbine (1) is located between two angles (6). The two-way ball bearings are installed in these. The two angles, the windbreak with the wind guides (3) and (8), and the windbreak side walls (4), are attached to the base plate (2).

6.4 If the wheel disc distance is more than 60 cm, a support disc (5) is required. It prevents the wind troughs from bending in strong air currents.

7.4 The wire bracing is attached to the windscreen with 4 supports, it prevents the large bearing plate (3) from bending. Two interacting wind vanes (5) are screwed onto the bearing plate. They align and stabilize the windscreen against the direction of the wind.

7.5 Installation of the wind turbine vertically

1. The supporting pillars are anchored on a concrete slab. The base plate (6) with the bearing block (10) attached is screwed onto the supporting pillars.

2. The wind turbine assembly (7a) is inserted into the shaft bearing in the bearing block (10).

3. The drive wheel of the double transmission is pressed onto the wind turbine shaft. The double transmission connects the wind turbine to the generator.

4. The windscreen assembly (la) with double bearing (2) is placed on the upper end of the wind turbine shaft. The windscreen can now be positioned against the wind direction using the wind vanes on the rotating wind turbine. The windscreen can swivel through 360°.

Benefits achieved

1.1 The advantages achieved with the invention are in particular that the windbreak brings more wind to the wind wheel or wind turbine. The size of the windbreak (larger than the wind wheel) prevents the countercurrent that occurs on one half of the wind wheel without a windbreak. The windbreaks, which are mounted opposite one another in the horizontal design, use all wind directions and require a swivel range of 2 x 90° (problem-free current dissipation).

1.2 The position and arrangement of the wind troughs prevents the air flow from slipping and guarantees 100% use of the captured wind.

1.3 The wind guides in the windbreak direct the captured air flow in a compressed state and at the most favorable angle to the wind troughs. This creates flow-free zones. This reduces the air resistance of the rotating wind turbine.

1.4 Due to the advantages described, the efficiency is increased several times over compared to existing wind turbines.

2.1 Vertical wind turbine system

This system can be installed cost-effectively on flat roofs. The high efficiency and low manufacturing, assembly and maintenance costs guarantee a good price-performance ratio and high economic efficiency. Systems with wind turbine sizes of 0:2 meters are planned.

3., 1 wind turbine in horizontal design (multiple ) The horizontal multiple turbine can be equipped with 3 wind turbines = 0.5 meters and has a windscreen area of 45 m ² . This amount of air is fed to the wind turbines without any loss. This could achieve about 1.5 times the output of a wind turbine with a rotor 0.30 meters.

3.2 A larger multiple system could be built at low cost to double the output. This would mean that a system with 6 wind turbines could produce approximately 3 times the output of the rotor-driven system shown on page 9.

This would make the construction of giant rotor turbines with heights of over 100 m, "as currently planned in the Black Forest", unnecessary.

Benefits achieved

4.1 Wk.-AnIage for cars

A further advantage is the possibility of using it to recover energy in the vehicle, especially in electrically powered vehicles, by using the headwind that occurs at the front of the vehicle when driving.

4.2 On page 6, Fig. Hu. 12 it is shown how by directing the resulting air currents via wind channels to the wind turbines installed in the vehicle, about 60% of the air to be displaced can be used to recover the energy used.

4.3 Technical data comparing wind turbines, (a) rotor drive versus (b) wind turbine drive.

The efficiency of a rotor system is reduced by the fact that the air flow slides off the rotor blade (50%) and the air resistance that occurs when the rotor blades rotate (17%). Efficiency = 33%.
