Renewable energy sources can have as many applications as one can imagine. Among them is the pumping of water for its use, for example for irrigation, among other possible uses.
An alternative to perform this operation without causing an increase in energy consumption is make a wind water pump, which provides the energy necessary to raise this resource. We explain how to create this mechanism, for which you will basically need skills and reused parts from old bikes.
Wind water pump instructions.
Step 1: Prepare the wheels and gears.
Much of the materials in this wind water pump are parts used from bicycles, which have been adapted to work for this purpose. This is the case with the gears, for which you will have to use the part you see in the picture (the cassette) and, as you can see, place bolts on its perimeter.
For the part that will go above the pump, use short bolts; while for the one who goes vertically, the lengths will be more suitable.
Next, attach the horizontal gear to the axle of a bicycle wheel. On the other hand, the rim of another wheel is fixed to the part by three metal supports.
Now you will need a sturdy tripod to attach a T-piece at the top to connect the PVC pipes. In this room you will need to install the wheel structure you created. In this case, it was chosen to do it with a few circular pieces of wood. Later, you need to install the vertical part horizontally with the connecting part for PVC, so that it does not interfere with its rotation.
Step 2: Create the wind sails.
Although we initially opted for pieces of fabric covered with plastic sheeting, the truth is that after several tests it was found that the system was not effective enough. Therefore, prepare five PVC or tin windscreen sails and attach them directly to the rims of the bike.
Step 3: Install the spark plugs.
In this step, you will need to drill five holes large enough for a bicycle spoke to go through them. Indeed, you will have to insert them to the rim so that they are well fixed, for example by means of epoxy, widely used in plumbing for its effectiveness of adhesion.
Once the epoxy dries, the sails will also need to be attached to the spokes of the bike. Fix them again with the same material and, if you want to strengthen the structure even more, screw the spokes to prevent the sails from falling.
Step 4: Make the pump connector.
If you check the vertical mechanism, you will see that on the back of the bolts you placed in the cassettes there is a small red ball. In fact, there are two, this one and another fixed on the piston of the water pump, thanks to which the wind turbine and the pump are connected so that the force of the wind is transferred to the water pump.
This connector is simply made of PVC tubing. In addition, several bicycle spokes were inserted, simply by heating the plastic, for example over a kitchen fire. Make sure this part of the system is as light as possible, otherwise it will need more air to function.
Step 5: Create the water pump.
To create the water pump, you will basically need a PVC pipe and a T-connector. If you follow the pattern in the picture, you shouldn’t have a problem getting everything to fit. Also, to help you in this step, you can watch this video.
Step 6: Repair the wind turbine and water pump.
To keep the system upright, firmly attach a metal rod to the floor where you want to place the equipment. Secure the metal rod to the outside of the pump using a screw clamp.
Then position the wind turbine on the pump so that it is high enough so that the link arm is fully extended. Finally, make sure to join the connector with the impeller horizontally and with the pump piston.
As the system can be somewhat fragile, you should ideally strengthen it by installing it on a 4 × 4 pole, which will eliminate unwanted movement.
With all these steps, the wind water pump will be ready. However, observing how it works and having received many suggestions, the promoter of this idea applied some improvements to increase performance. They are as follows:
- Replace the tripod with a metal pipe throughout the system.
- Move the valve closer to the ground so that it is not necessary to pump the water so high.
- Replace the piston and PVC arm with bicycle shocks.
- Unhook the sails from below and leave them anchored to the structure from above, so that they are in “attack mode”, which will offer more flexibility and promote thrust.
Now, with these latest recommendations, everything is ready for you to start your wind-powered air pump.
