Description

  The present invention relates to a horizontal running water power generation apparatus, and more particularly to a horizontal running water power generation apparatus suitable for installation in a large number of remaining waterways for domestic and overseas water turbines.

  In recent years, awareness of the environment has increased, and various efforts have been made to utilize natural energy. Among these, with regard to power generation, since power generation using hydropower has already been developed, attention is being focused on power generation using wind power, tidal power, geothermal heat, sunlight, and the like.

However, the inventor thinks that it is an early measure that power generation using hydropower has already been developed and exhausted. In other words, the fact that it has been fully developed out of hydropower is related to power generation by constructing a dam and using the energy of its head.
This is not the only energy of water. The inventors particularly paid attention to the flowing water flowing through the water turbine channel. That is, the history of water turbines is old. For example, in Europe, many water turbines were installed in the 11th to 13th centuries, and 90,000 water turbines were operating in France alone. In Japan, waterwheels have been popular since the Edo period.

  Many of these turbines have finished their roles in the subsequent development of steam engines, internal combustion engines, electrical energy, and the like. However, many waterways for waterwheels still exist and continue to flow. For example, most of the above 90,000 units in France and about 40,000 units continue to flow in Japan. In this case, the watermill is near the house. Therefore, the waterway is naturally near the house.

This is a great advantage. Because of this, running water naturally exists in natural rivers. However, the position where a flow velocity suitable for power generation is obtained is not necessarily near a house. For this reason, even if power generation is possible, an electric circuit must be laid in order to supply it to the consumer's home. This is not profitable.
In this regard, the waterway for water turbines is close to the house from the beginning. Therefore, if a power generation device is installed here, electric power can be easily supplied to a house.

In this case, a structure in which a floating base is floated on running water and a water wheel is arranged on the water is preferable because of easy transportation and installation. Many such power generation devices have been proposed in addition to those described in Patent Document 1 below.
JP-A-5-256246

  However, as far as the inventor knows, there seems to be no example of continuing power generation by installing a power generation device in such a waterway for a water turbine. The inventor considered the reason. As a result, it turned out that this kind of conventional power generation device has a small amount of power generation for the installation cost and may not be profitable, and it seems that it is not continuously implemented for this reason. .

  That is, in the conventional power generator, a circular water wheel was still used. If the water wheel is circular, for example, as shown in FIG. 9, the water wheel is not sufficiently filled with water in each water receiver l, and the water wheel rotates. Or when located in the lower part, since the effective radius with respect to a rotating shaft is small, the energy of water cannot fully be taken out.

  In addition, even in the case of the underhanging type, if there is only a part of the slats, for example, 18 slats, it is about one fifth that is immersed in the spilling water, about one fifth of that. Moreover, since the blades are not directly facing the running water when entering and exiting the running water, the energy of the running water cannot be sufficiently extracted.

  The object of the present invention is to solve such a problem, and when generating electricity using running water, it is possible to draw out the energy to the maximum. The present invention is to realize a suitable flowing water power generation apparatus applied to the above.

  In order to solve the above-mentioned problems, the invention of claim 1 includes an upstream rotating body arranged on the upstream side, a downstream rotating body arranged on the downstream side, and a tension between the upstream rotating body and the downstream rotating body. A suspended traveling body and a blade plate attached to the traveling body and receiving the energy of running water and circulating the traveling body.

  The invention according to claim 2 is an upstream rotating body disposed on the upstream side, a downstream rotating body disposed on the downstream side, and a circuit stretched between the upstream rotating body and the downstream rotating body. A belt is stretched between a body, a blade that is attached to the circuit body and receives the energy of flowing water and circulates the circuit body, and two multi-stage pulleys arranged in opposite directions, and the upstream side And transmission means for transmitting energy to the generator from either the rotating body or the downstream rotating body.

  Further, the invention of claim 3 is that the anti-slip is provided on at least the surface of the rotating body that outputs energy to the generator among the upstream rotating body or the downstream rotating body according to claim 1 or 2. It has been subjected.

  Further, the invention according to claim 4 is provided with the anti-slip as defined in claim 3 with aramid fibers.

According to the first aspect of the present invention, the slats attached to the circulating body are opposed to the running water and move parallel to the running water. Thereby, the energy of flowing water can be taken out much more efficiently than the conventional circular water wheel. According to the inventor's estimation, it is possible to extract 2 to 3 times as much energy as that of the conventional circular water turbine. Moreover, sufficient energy can be extracted even from a channel with a low flow velocity.
Therefore, where there is running water, especially when it is applied to a large number of waterways for water turbines that are still in the vicinity of people's houses, power generation can be started immediately without any need for electric circuit work and waterway work. A gentle and inexpensive power generation system can be realized.

  Further, according to the invention of claim 2, in addition to the effect of the invention of claim 1, by changing the position of the belt, the rotational speed of the generator can be kept appropriate regardless of the speed of running water. And wherever it is installed, power generation can be started immediately.

  Further, according to the invention of claim 3, in addition to the effect of the invention of claim 1 or claim 2, slippage between the rotating body and the circulating body, which is likely to occur due to getting wet with water, is prevented, and is taken out by the blade. The energy of the flowing water is supplied to the generator without any loss.

  According to the invention of claim 4, in addition to the effect of the invention of claim 1 or 2, the slip prevention between the rotating body and the circulating body is further ensured, and energy loss is completely prevented.

The details of the present invention will be described below based on the embodiments shown in the drawings. 1 to 8 show a horizontal running water power generation apparatus 50 according to an embodiment. In each figure, reference numeral 1 denotes a float, which is formed by connecting two floats 2 and 3 with crosspieces 4, 5 and 6. The float 1 is locked with a chain 9 (not shown) driven to the side of the waterway 8 for the water turbine.
It is not necessary to lock the float 1 with a chain. For example, a resin or hemp rope may be used. A wire may be used. When the waterway 8 for the water turbine increases, it is possible to easily move to the land by removing the chain 9 and the like, and to prevent the horizontal running water power generator 50 from being lost.

  A support plate 11 is attached on the upstream rails 4 and 5, and a generator 12 and a transmission 13 are disposed thereon. These generator 12 and transmission 13 are covered with a transparent acrylic cover 14. An upstream drum 15 and a downstream drum 16 are supported by the left and right floats 2 and 3 via bearings 17, respectively. A sealed bearing is used as the bearing 17. Thereby, there is no water penetration | invasion to a bearing and durability of the apparatus 50 increases. A circulating belt 18 is formed of a wide rubber band and is stretched between the upstream drum 15 and the downstream drum 16.

  Twenty blade plates 19 are attached to the circulating belt 18 at predetermined intervals. The structure of the blade 19 is as shown in FIG. 5, and the details of the attachment are as shown in FIG. The vane plate 19 includes a wall portion 21 that is perpendicular to the circulating belt 18, an attachment portion 22 that extends from the lower end thereof, and a rib 23 that connects them. The wall portion 21 is bent in a mountain shape on the downstream side with a peak 24 at the center, and three hooks 26 are passed through the attachment portion 22 and attached to the circulating belt 18. By making the peak 24 downstream, the movement of the running water 27 is reliably captured.

  Further, by using the circulating belt 18, the wall portion 21 moves in parallel with the running water 27. Thereby, the movement of the flowing water 27 can be captured for a long time as compared with the circular water wheel. Furthermore, in this embodiment, running water 27 is captured by a plurality of blades 19. In combination with these, the inventors have calculated that in the case of this embodiment, about three times as much energy as that of the conventional circular water turbine can be extracted. Further, the wall portion 21 is rounded at both ends 28 at the front end. As a result, the resistance when the blade 19 enters the running water 27 is eliminated, and the circulation of the circulation belt 18 becomes smooth.

  The transmission 13 includes two multi-stage pulleys 30 and 31 arranged in opposite directions, and a V-belt 32 is stretched around the pulley. Ordinary pulleys 33 and 34 (single groove pulleys) are respectively attached to the other ends of the rotary shafts to which the multistage pulleys 30 and 31 are attached. Correspondingly, ordinary pulleys 36 and 37 are attached to the upstream drum 15 and the generator 12, and V-belts 38 and 39 are respectively stretched. Thus, the movement of the blades 19 is transmitted to the generator 12 to generate power.

Changing the position of the V-belt 32 of the transmission 13 is simple. The generator usually has an appropriate rotation speed. Although the speed of the flowing water 27 varies depending on the installation location, the position of the V-belt 32 can be easily changed, so that there is an advantage that it can be installed anywhere.
The structure of the transmission is not limited to this. Furthermore, some generators have a constant output voltage regardless of the rotational speed. If the storage battery is once stored and output, the generator speed itself is not a problem. In such a case, a transmission is not necessary.

  The upstream drum 15 is rotated by the movement of the circulating belt 18. The upstream drum 15 and the circulating belt 18 are immersed in water. This may cause slip. In order to prevent this from happening, a string of aramid fibers is tightly wound around the surface of the upstream drum 15 (41). Non-slip is not limited to aramid fiber. For example, a number of protrusions may be provided on the surface of the upstream drum 15 in parallel with the rotation axis. However, the aramid fiber string has high frictional resistance, and it only needs to be wound. Therefore, it is optimal as an anti-slip here. The downstream drum 16 merely tensions the circulating belt 18. Therefore, there is no need to worry about slipping and no slipping is necessary. Depending on the material of the upstream drum 15 and the circulating belt 18, there may be a case where it is not necessary to prevent slipping. For example, if the upstream drum 15 is made of wood, there is some concern about durability, but slipping is unlikely to occur.

Here, as a precaution, the relationship between the configuration of the embodiment and the configuration of the claims will be mentioned. Each drum 15 and 16 hits each rotating body. The traveling belt 18 hits the traveling body. The transmission 13 hits the transmission means. Since the other names use the same names, explanations thereof are omitted.
The rotating body and the circulating body are not limited to the drums 15 and 16 and the circulating belt 18. For example, two ordinary single-slotted pulleys are attached to each rotating shaft to form each rotating body, a V belt is stretched on each rotating body, and a blade 19 is attached to these parallel V belts. May be.

Finally, the history of the watermill that became the motive for the present invention will be described. There are parts that overlap with the previous descriptions, but that seems to be easier to understand, so keep that in mind.
At least 40,000 water mills were operating for rural power in the pre-war period, but about 500 are still operating nationwide. The decline of water turbines began in 1965 and 20 years, and peaked in 1955 and 1955 after the war. Instead of water turbine power, oil turbines and electric motors were substituted.

  This phenomenon has the same tendency not only in Japan but also in developed countries in Europe. It is said that in France, before 1900, 90,000 water turbines were in operation for milling. It is a little surprising that France, which has not changed much with the size of Japan, has more than double the size of Japan. Anyway, I was able to understand something surprising because of the watermill.

  In the long history of mankind, people have utilized natural energy by utilizing the wisdom of human beings. As one of them, during the 11th and 13th centuries, water turbines were built on a large scale in various places in Europe. The reason for this is that bread is a regular diet, and milling wheat in Europe is an indispensable task. This means that water turbines were made on a large scale at various locations for use in the future. Therefore, it may be said that it was a historical fact that 90,000 turbines were operating in France alone.

  The fact that the water turbine was built on a large scale means that there was always a water channel built for the water turbine at the place where the water turbine was installed. If a mill and a mill are left for 100 years, even if they have been destroyed and disappeared, only the waterway should remain and remain. And even though it is not used for water turbines now, the clean water from the mountains that has been flowing since ancient times will still flow, reflecting the changes of the times, the history and the appearance of the farmers.

  Speaking of Europe in the 11th and 13th centuries, most of the countries on the continent were agricultural. Therefore, the fact that a large number of water turbines were built in various places supports that there were almost the same number of waterways. And in order for abundant water to flow through the waterways, there must be a mountain that is the source of the water, but fortunately there is an Alpine mountain range (750 km in length and 200 km in width) that has a huge water retention capacity in Europe. There is even a glacier, and France, which borders the Swiss federation, which covers most of this huge mountain range, has the Pyrenees to the south and borders Spain.

  The snow and rain that fall in these two mountain ranges become sources from the mountains of the Alps and Pyrenees, and innumerable flows pass through the surrounding countries, gathering many tributaries along the way, becoming the mainstream, and pouring into the sea. The sea flows north to the North Sea, south to the Mediterranean, northern France to the Doba Strait, west to Spain to the Atlantic Ocean, northern Germany to the Bay of Biscay and the North Sea, and east to the Danube River to the Black Sea. Head over. In this way, 90,000 turbines were operating in France alone, which means that there were 90,000 turbines using rivers flowing through the Alps and the Pyrenees. By analogy with this, it can be estimated that the neighboring countries, such as Germany, the Czech Republic, Austria, Slovakia, Hungary, Italy, etc., which are adjacent to the Alps, were at least three times as large as France. Furthermore, in all Europe, including Spain, Portugal, Eastern Europe, and Scandinavian countries, if there were five times as much as France, the number would actually be 450,000, which is 11 times that of Japan, 40,000. It seems that there is no doubt 10 times at least.

  Since these turbines are used as a power source in rural areas, most of the turbines scattered throughout the country, regardless of whether they are east or west, are present at many points between mountainous areas and plains. Since a watermill is selected and is installed, it is located in a place with a relatively large amount of water and a high flow velocity, and has characteristics that are not found in natural rivers. Furthermore, most of these canals are well-manufactured and maintained, with a canal width of about 1 to 1.5 m, a depth of about 50 cm, and a flow rate of about 0.5 to 1 m on average. Because of the flow velocity, this canal can be said to be the best and optimal channel that should be utilized for running water power generation.

  As described above or in the background section, the inventor of the present invention is that the inventor has focused on the advantages of the waterway for water turbines. However, the present invention is not limited to installation in a water turbine channel. It would be profitable if an electric circuit is unnecessary even in a natural river, and the efficiency has been dramatically improved, so it can be installed in a location that requires an electric circuit. Furthermore, the present invention can also be applied to artificial rivers and waterways such as agricultural water and industrial water.
