Consequently, implementation of our project is instrumental in creation of a new cheap and accessible innovative technology for the improvement of the ecological state of various reservoirs.
Introduction:
Contamination of superficial and underground waters became the problem of the entire densely populated countries of world. The principal reason of contamination is an upcast in reservoirs by the industrial enterprises of unrefined flow waters, and also troop landing in water of various garbage. Contamination of reservoirs results in impoverishment of vegetable and animal world, related to the water environment. Western Ukraine experiences the row of the hard ecological problems now. An unfavourable ecological situation was folded on rivers and reservoirs of it. The state of majority reservoirs causes a serious alarm, as are contaminated by industrial and sullage sewage, by washing off from motor-car ways.
Aquatoriums are muddy by the most various rubbish, littoral areas are chocked up, a plenty of strange objects accumulated on a day. All this dangerously for the health of man. Reservoirs suitable for bathing on the territory of the most of cities are not present.
Materials and Methods:
First of all, the literary sources have the information about the ways and methods of purifying the sewage. And almost nothing is told about the purifying of the basins from the rubbish, which is thrown out to the water by unconscious people. But just exactly this problem is the most important for the lakes and basins, because there are a lot of plastic bottles and packets, wrappings from biscuit and chips at the bottom, even automobile tires can we find in the water. This problem needs to be immediately solved, because the biological processes of self-renovation cannot include foreign synthetic objects made by a man.
There is almost no literary about the using of own forces. It is very hard to do and needs a big physical strength.
There is any word about using a definite technology for purifying the basins, which will be cheaper, simpler and needn't so much people to do such work. That is why we decided to propose an example for you, which is based on an old technology and was used by old Greeks. It is called Screw of Archimedes. We call it "The clearing water-pump". It was used for taking up the water for watering the fields. There were used animals or slaves instead of the motor.
The technology, which is proposed, includes next actions the wind moves the propeller (of electrical motor can be used) connected with the screw, which is made of metallic pivot and spiral, begins to work. The water goes inside and then goes out through the tap. Here it goes to the filter, which is made of net. This filter keeps the rubbish and lets the water.
Results:
As a result of creation of a similar aggregate the task of those will be facilitated, who desires to conduct cleaning of reservoirs. He far simplifies work of man at cleaning, and also limits the quantity of people, which is needed for this purpose.
The use of the aggregate it is enough simple and accessible. Depending on possibilities of producers of aggregate, he can work both thanks to strength of wind, and on an ordinary motor from electric power. Consequently, implementation of our project is instrumental in creation of a new cheap and accessible innovative technology for the improvement of the ecological state of various reservoirs.
Consequently, as a result of implementation of project it is foreseen to get a simple and simple in exploitation mechanism for cleaning of reservoirs, which will become in the adventure all persons interested. He not necessarily needs the use of electric power that more frequent all expensive and it is difficult to carry out. She can be replaced by energy of wind, and it is another advantage of our vehicle.
Discussion:
In literary sources there mainly is no question about the use of definite technologies for cleaning of reservoirs, and is written simply: to "clean a reservoir". But this not so it is easily to do, both seems at first. Necessary heavy physical and material tolls both on instruments (buckets, to burst, rakes and others like that), and on vehicles transport, by which take out garbage. Already not speaking it about the huge number of people which are needed to involve to a similar action.
And for this purpose needed either again money on a pay-envelope to these people, or enthusiasts which at us not so already and much... Possibly, to somebody the offered idea will seem inefficient. But this not so, all methods which were offered for cleaning of reservoirs to this pores, are difficult and need large force and money. Instead we offer a small aggregate which simply to do from at hand materials: plastic, foam plastic, tree, aluminium, net and others like that. All these materials can be as easy as anything found or inexpensively purchased in the proper shops. "The cleansing water-pump" will give possibility to conduct cleaning up of territory of muddy reservoirs to all persons interested, for which such decision of problem will become real and accessible. In addition, to clear water it is possible played, say, rolling on a catamaran or cutter with the fastened device.
Conclusions:
Consequently, as a result of implementation of project we will have a simple and not complicated in exploitation mechanism for purifying of reservoirs, which be necessary for all persons interested. It is not necessary for it to use electricity, what is sometimes expensive hard to do. The electricity can be replaced by the energy of wind. This is one more advantage of our apparatus. In the working variant the screw must be making on the factory and the tube must be bent.
Our project is directed on making of simple and simple in exploitation mechanism for cleaning of reservoirs, which will become in the adventure all persons interested. As a result of creation of a similar aggregate the task of those will be facilitated, who desires to conduct cleaning of reservoirs. He far simplifies work of man at cleaning, and also limits the quantity of people, which is needed for this purpose. The use of the "purifying water-pump" is enough simple and accessible. It is not necessarily needs the use of electric power, which more frequent all expensive and it is difficult to carry out.
It can be replaced by energy of wind, and it is another advantage of our vehicle. Consequently, implementation of our project is instrumental in creation of a new cheap and accessible innovative technology for the improvement of the ecological state of various reservoirs.
