DE10045601A1 - Flexible wind generator holder for supplying electric current e.g.. on board yacht with total construction of refined e.g. stainless steel and plastic - Google Patents

Abstract

The holder is designed with a tubular mounting of the wind generator by a plastic sleeve led around a fixed welded metal tube. A stand tube of appropriate length is provided, which is interrupted in the vicinity of the wind generator by an elastic holder of movement absorbing material with interposed metal discs, fixed with each other but relatively flexible, and the metal discs themselves are connected with the stand tube. The inner lying cable supply is protected by an outer sleeve of conical shape of plastic.

Description

1. Technical field

The invention comes from the field of electricity since it the area of alternative electricity production is. The example "water sports" is dealt with here.

2. State of the art

Wind generators are becoming increasingly popular alternative energy generation used. This is true especially towards large units that everyone in so-called wind farms at suitable locations in the country can watch. However, in recent years also developed powerful, smaller generators that on sailing yachts, lonely houses or similar come. Here is the example of energy generation a sailing yacht treated because of the care of one Yacht with electricity always problems has prepared.

Owners of sailing yachts choose a wind generator for a variety of reasons, but these will not be explained in detail here. Here it is important that the position of the wind generator on board must meet some important criteria:

• 1. As free flow as possible through the wind;
• 2. No hindrance to the sails or the like;
• 3. No endangerment of people through themselves fast rotating propeller wing.

Observation of these 3 points led to an almost exclusive position of the wind generator at the stern of the ship on a special frame at a height of around 3 meters (see Fig. 1). The vertical standpipe is then supported to the front and to the side with two pipes. This is very important so that the standpipe with the wind generator can withstand the movements of the boat in the rough sea. In the example of the wind generator used here, the manufacturer recommends that the standpipe has to withstand a horizontal (!) Force of 70 kg.

Wind generators usually start to work at around 3 wind speeds. The air then moves at 3-4 m / s. Then the wind blades turn very quickly and generate unbalance and vibrations. These cannot be avoided, but should be as low as possible (see Fig. 2). The manufacturers strive for tolerance-free production and wind blades of the same weight as possible, since they cannot be "balanced" with small weights like a car wheel.

Because the speed of rotation of the wing with more wind this point is particularly important. To rule out any danger to people and Allowing the wind generator to flow well is one sufficient installation height required. This is included about 3 meters. Slight vibrations through the So wind generator are on the standpipe and the transferred two support tubes and by the length of the Reinforced pipes. A transfer to the hull must definitely be prevented. If you sit in the ship you can feel the vibrations, the dishes and cutlery rattles and This applies not only to steel ships, but also also for plastic yachts.

So far, there is only one way to install a "suspension": it is the variant shown in Fig. 3. Here the vibrations of the frame are intercepted by three rubber buffers without a direct metal connection at the assembly points on the boat.

As can be seen from the illustration, the tube ( 1 ) stands on a rubber buffer ( 2 ) which protrudes into the hollow tube and is glued there. The rubber buffer under the tube is wider than the tube so that it does not come into contact with the deck itself. The stable assembly is carried out by means of the central threaded screw ( 3 ) and the combination washer / nut below deck.

The main disadvantage of this construction is that due to the Unbalance in the wind generator for a long time Assembly frame swings. So if you stands at the stern, for example, and hold on to it is very uncomfortable. Can also Unintentional screw connections from assembly to solve. On the other hand, the larger Collect dirt, dirt, rust, etc. Owner of a Ships with a teak deck will want to avoid that and must.

3. The problem underlying the invention

As already described above, a new one was urgently needed Bracket for the wind generator to be developed no more vibrations on the mounting frame transfers. Then you can hold on to the frame, without getting uncomfortable and no screws unintentionally come off. There is also the advantage that the mounting surface of the generator frame on Minimum is decreased and others Fastening options (pushpit or similar) used can be. This will u. Maybe less Drilling required on the boat deck, and under Rubber panels can't rot a teak deck or that Rust the steel deck unnoticed.  

5. Commercial application

Wind generators are becoming increasingly popular Yacht owners. Over time, their accomplishments been improved so that this alternative Energy generation is worthwhile. However, there are those among the Points 2 and 3 described problems. This one solution presented enables all problems with to solve once and is so convincing that this elastic wind generator bracket on the market will enforce.

6. Beneficial effect

The advantages of the wind generator bracket presented here are in the following points:

• a) Immediate damping of the vibrations on the polluter himself Vibrations on the mounting frame or the Transfer hull.
• b) The internal cable routing protects the Cable from damage and Weather.
• c) Damage to the bracket or the Standpipe through the wind wing excluded, even if their tips bend slightly backwards in the storm. The elastic bracket compensates for this by backwards accordingly dodging.
• d) By using plastic for the Protective cover there is no risk of corrosion, and the suspension is from UV rays and the Protected from the weather.  
• e) By eliminating the vibrations this can be relatively close to the wind generator Bracket also for equipment carriers and the
• f) mast assembly can be used.

b) Practical manufacture

As can be seen in Fig. 1, the wind generator stands on a vertical standpipe at the stern of a sailing yacht. It is protected against falling over by two supports. One prop leads forward and supports against the movements that the ship makes in the transverse axis. The other support tube, which supports the standpipe against movements in the longitudinal axis, is not shown. It leads across the ship's longitudinal axis to the other side of the stern. The manufacture of this "base" does not represent a high standard of craftsmanship and must be carried out cleanly and adapted to the respective ship. It is an activity from the normal day-to-day work of a craft company and is therefore not described in more detail here.

The actual production of the actual invention, ie the elastic wind generator holder, is carried out as follows (see Fig. 5):
The lower standpipe ( 1 ) is cut off horizontally at the top. The first disc ( 9 ) is welded onto it after a hole with a diameter of 11 mm has been drilled in the center and a M 10 nut has been welded to the center underneath the hole. Now the picture is ready so that the elastic holder can be started.

A threaded stand ( 11 ) is welded to the center of the next stainless steel washer ( 9 ). The next 3 rubber buffers ( 7 ) are now glued to the 2 thin stainless steel discs ( 8 ) using industrial contact adhesive. A threaded stand ( 11 ) is welded in the middle of the upper stainless steel disc ( 9 ) and glued to the last third rubber buffer. While the glue is tightening, you can work on the upper tube. It is 150 mm long and is welded to a stainless steel washer ( 9 ) at the bottom, which in turn was previously drilled in the center and welded on the inside with a suitable nut ( 10 ).

After the adhesive has hardened, the middle part (B) is screwed onto the lower part (C). Now you can drill the cable ( 16 ). The position of the hole must now be marked on the outside of the pipe. Then the upper part (A) can be screwed onto the middle part (B). Now the marking is transferred to the upper part and the hole for the power cables is also drilled.

A supplier produces the cover ( 12 ). As Fig. 5 shows, the cover can now be placed over the threaded screw ( 11 ). It is pulled down until the entire elastic connection is covered.

The upper part of the pipe is now processed further. The stainless steel disc ( 15 ) that was previously drilled is now welded onto the upper pipe opening. Then the small assembly tube ( 14 ) is welded exactly in the middle of the pane or over the central hole. This is used for cable entry.

In the case presented here, the wind generator (see Fig. 4) must be screwed onto a tube with a diameter of 48 mm. This is achieved by using a turned, suitable plastic part ( 13 ) which is attached and glued around the tube ( 14 ).

The different diameters can be seen again in Fig. 8.

Before screwing the wind generator, the 3 cables through the lower standpipe and through the hole be passed through in the "elastic bracket". Now you can use a luster clamp or something similar to the outstanding cable for the wind generator be connected.

Fig. 4 shows the finished assembly of the wind generator on the standpipe.

8. How it works

The method of operation of the invention presented here is very simple: Fig. 4 shows the finished assembly of the entire unit in a side view. The wind coming from the left drives the generator with the help of the 3 wind blades. These are narrow at the tips and bend backwards in the storm. Even without an "elastic bracket" you will not touch the standpipe, because this bracket is so new that it has not yet been possible to deal with it. The vibrations emanating from the wind generator are absorbed by the triple rubber suspension (see Fig. 5). The plastic cover protects this rubber suspension from harmful UV rays and weather conditions. The conical shape guarantees that rain or the like drips well and the "elastic holder" can give in to the wind pressure. At no time does the lower edge of the cover come into contact with the lower standpipe, so that no vibrations can be transmitted here.

Protection of the rubber suspension and the solid Processing of the entire system guarantee a long lifetime.  

Added to this is the resilient effect on the wind generator mount (see Fig. 7). The turned part made of plastic is more elastic than it would be metal; In addition, the metal clamp of the wind generator itself is additionally lined with rubber on the inside.
