THE WINDMILL WITH WINDMILL

 

We are talking about a pump unit driven by a windmill. Even in relatively weak wind she takes in the water tank well water or shallow wells, and it can be done continuously and with pauses.

 

It should be noted that the lifting operation with the help of wind turbines has long been practiced in the Netherlands. And more recently, on the decks of wooden barges were set a simple wind turbine that powered pump is constantly pumping water from the holds.

There are many designs of water-lifting devices driven by a windmill. So, effectively working a chain pump, which draws water from the well with the “endless” chain, consisting of a number of vessels. A variant of such a water can be seen on one of the drawings. As the vessels used are small (half-liter) plastic bottles of carbonated drinks, you only need each to cut a couple of holes through them, the tanks will be filled with water and emptied. In the bottom of each bottle must be drilled the hole and it is passed the stud with two holes , which is fixed by a pair of nuts. In the holes are introduced wire rings in them, and nylon cord.

 

Gathered from such links in a closed chain hung on a drum welded from 12 mm steel bars and bushings-tubes, and those with two asterisks and the Bush of the Cove, the chain transmission is connected with the shaft of the wind turbine. The wind will blow, spun the windmill and with it the lifting shaft of the drum. Small container vessels, but for an hour or two can be filled with water several 200-litre barrels!

 

Using bottles, you can build an equally efficient pump. Most importantly, choose a half-meter section of pipe of metal or plastic with an inner diameter below it with a slight effort was part of the pistons, the lower part half-liter plastic bottles. Most likely, a tube will have to be machined and sanded to bring its inner diameter to the desired size. Part of the bottles (the pistons) are connected in a single chain is exactly the same as in the previous water — distance between them must be less than the length of the pipe-cylinder. The latter is fixed in the well and is built on top of the pipe of larger diameter or even a wooden box of square section. The rotation of the turbine drives the lifting drum when you move the pistons of which consistently fall into the cylinder, capture water and deliver it to a top tube or box, on which she rises to the water tray.

 

Chain water lift:

 

1 — drum; 2 — water vessels (plastikovye bottles of 0.5 l); 3 — Cup; 4 — water pipe; 5 — tank; 6 — nylon cord

 

Link lifting chain:

 

1,6 — nylon cord; 2 — water vessel; 3 — plastic bottle-processing capacity of 0.5 l; 4 — stud with two nuts M6; 5 — ring

 

 

 

 

 

But the most effective pumping wind turbine, which is a pyramidal truss support, the top of which is mounted a windmill, pump and water capacity.

 

Bearing is welded from steel profiles type “area” section of 40x40x3 mm with the use of spit-knock-amplifiers thickness of 3 mm. it is also easier to pre-cook two flat farm, and then fixing them relative to each other with a few struts to connect the parts into a single spatial structure. In the lower part of the frame is welded on four round flange, each pre-drilled four holes for the mounting studs with M10 threaded hole.

 

Support is fixed on a concrete Foundation piles, formed directly in the wells selected hand drill. Previously in each of the wells goes down rolled roofing material from a hollow cylinder — shape and waterproofing of a future column. Above ground, the Foundation should be approximately 0.2 m. In the process of bookmarking in the form of a concrete mixture are reinforcing bars and threaded studs of the mounting support. The last pre with the nuts fixed to the jig is a plywood plate with holes drilled in accordance with the holes on the mounting flanges of the support.

 

Wind turbine — low-speed, four blade-wings of the soft type, modeled after the sail of a windsurfer, which is known to have high traction qualities.

 

Central bushing of the wind turbine is welded from steel pipe: it consists of a shaft and four nests (Stasov, in sailing terminology). The basis of each blade is a wooden rod (mast) is a conical bar length of 2100 mm and the diameters of its ends are 40 mm and 25 mm. After processing with planer rods are polished with sandpaper and covered with two or three coats of hot linseed oil. At the top of each mast mounted hardware fittings — steel sleeve welded to it with four eyelets for fastening wire braces.

 

Blade-sails sewn from airtight fabric used usually for light coats and jackets jackets. The layout of the sail is made on a level floor: first draw the basic triangle ABC, then from the back and bottom sides are deposited quantities “sickles” and points A and C, as well as A and b, connect a smooth radial curve.

The sail is cut in the shape of four panels of fabric and the seam lines must be perpendicular to the side of the primary AB of the triangle ABC. Incorporation of rear and bottom satorin is made with synthetic ribbons (tapes) of suitable width. Armor is most convenient to cut out a plastic W-shaped profile used for mounting of glass engines in bookcases. The mast (the rod of the blades of a windmill) is put on the sail with mast pocket, and a fixed nylon startcom, passed through the grommet in falevai plank, sails and fixed on the duck.

 

The wind turbine is mounted on a rotary device, which is based on the wheel of the car “the Gazelle” or “field”, freely rotating on four rollers. On a rotating device by welding fixed steel pipe with a pair of nylon bushings (bearings) in which the rotating shaft of the wind turbine with a crank. The latter by means of the connecting rod through the ball joint connects to the stock pump. The shaft is of steel pipe, crank is welded from a piece of square tube and round the finger with a threaded shank.

 

It should be borne in mind that the eccentricity of the crank (and hence piston stroke) should be chosen depending on the dominant in this place wind speed: the higher it is, the more you can choose the stroke and the greater the performance patronesses installation. To calculate these parameters is difficult, it is easier to make several cranks with different eccentricity and choose the best.

 

On the shaft of the wind turbine mounted brake Assembly, representing the hub and the brake shield from a motorcycle “Is”. Brake lever on the shield is connected with a nylon cord — if necessary, the cord is tensioned and the blades slow down. By the way, to slow down the windmill you can purely hydraulically punching ball valve in the delivery pipe (after the pump). If you close it using the same nylon cord, then the wind will turn the windmill. After deceleration of the wind turbine should be deployed sideways to the wind direction and locked in this position by a pair of cords-RA-ties.

 

The pump is a cylinder with the piston in its upper part has six holes, closed with a six-petal valve. The same valve is in the well or sump, so that when the piston moves upward opened hole of the intake valve and close the valve holes of the piston and when the piston moves from the top down open a hole in the piston and closes the holes in the intake valve. Thus, when the reciprocating movement of the piston the water portions served in a water tank.

 

 

 

 

The pump body (cylinder) are made of cut steel pipe, which is welded to the two flanges with six holes for the M6 bolts that secure the top and bottom of the pump cover. In the upper cover is a sleeve rod guide, and bottom welded steel angle plumbing coupler. Piston pump — dural, chiseled with a nylon seal ring. A six-petal valve cut from hard rubber with a thickness of 3-4 mm.

 

At the rear of the rotary device welding is attached to the stabiliser of wind turbine steel tubular frame on which is stretched a triangular piece of cloth synthetic fabric (the same that went into the making of the blades of the sail).

 

As already mentioned, metrosta-novka simultaneously performs the functions of pump and water tower. The water tank is located on the third “floor” truss support. It is made of simple wooden planks and is, in fact, the box, the tightness of which is ensured by reinforced plastic film used for greenhouses or polytunnels. Despite its modest size, the tank holds over 800 gallons of water.
