It may be used for heater operation on roads that may freeze, and for melting snow on roads. On the other hand, the same can be said for the other embodiments described below. However, water energy is not only used for power consumption, but also for hydraulic pressure (including hydraulic motor drive) or air pressure generation. is there.
[0009]
1 and 2, reference numeral 1 denotes a water flow point such as a river or a water channel. Water flows from above as indicated by an arrow in FIG. 1 and from the back side to the front in FIG. Reference numeral 2 denotes a bottom surface, through which a water turbine, which is a main part of the energy conversion device, is fixedly installed.
[0010]
The water turbine includes a fixed shaft 3 that is a vertical shaft. The fixed shaft 3 may be driven into a bottom plate like a pile, but is preferably firmly fixed via a foundation block 4 as shown in the figure. Reference numeral 5 denotes a base bracket for stabilization.
[0011]
Around the fixed shaft 3, there is provided a central rotary body 6 that is closed vertically and has a hollow cylindrical shape that generates buoyancy so as to be able to follow the water level, and is movable up and down with respect to the fixed shaft 3.
Although the central rotating body 6 itself generates buoyancy, the buoyancy may not be obtained in a predetermined manner. For example, the buoyancy may be adjusted afterwards by adding water.
On the other hand, the central rotating body 6 itself has a simple structure such as a plate shape or a simple cylindrical shape, and has a structure in which a buoyant body can be added as necessary. Although not provided, the side of the water receiving rotating member (blade) 7 described below can be provided with buoyancy generating means or buoyancy generating means. These can be said similarly in other embodiments.
[0012]
Further, it is desirable that the central rotating body 6 moves smoothly up and down with respect to the fixed shaft 3, so that a repulsive relationship is provided between the central rotating body 6 and the fixed shaft 3, or a screw is interposed between the two. The water pressure may be added depending on other factors.
[0013]
The water receiving rotating members 7 have a curved shape that easily receives a water flow, and may be of other shapes such as a straight plate or a hemisphere. The bases of the water receiving rotating members 7 are fixed to the outer periphery of the central rotating body 6 in a radial arrangement. The water receiving rotation members 7 are rotated by being immersed in the water flow place 1 in a submerged state as shown in FIG. As shown in phantom lines in FIG. 1, the water receiving rotation members 7.. You may make it halve.

In order to reduce the resistance at the half-circumferential portion where the water receiving rotating members 7 are opposed to the water flow, the water flow guide plate 8 prevents the water flow from the upstream from hitting the water receiving rotating members 7 at the outer peripheral position of the track. Is fixed by using the fixed shaft 3 or by a separate fixing means.
[0015]
The rotational energy generated thereby is transmitted from a drive gear 9 provided on the central rotating body 6 so as to move up and down together with the rotating body 6 to a driven gear 10 meshing with the driving gear 9. 11 is a horizontal member, and the horizontal member 11 is spanned between the fixed shaft 3 and a river side bank (not shown), and it is free to add a support post in the middle. A transmission case 12 is provided on the upper side of the horizontal member 11, and a chain 14 hung on a sprocket 13 interlocking with the driven gear 10 is provided in the case 12 so as to be freely circulated so that it can be converted into electric power. It can be converted into hydraulic or pneumatic pressure.
[0016]
Instead of the transmission means using the gear, it may be configured to allow direct transmission by a combination of a sprocket and a chain or a pulley and a timing belt.

For example, magnets, barley stones, microorganisms, activated carbon, porous ceramics and the like.
Furthermore, each of the water receiving rotating members 7 may be provided with a sign such as a seal applied with a luminous paint or a sign for promoting environmental improvement.
Further, as shown in FIGS. 1 and 2, the first fixed guide 16 that guides the water flow from the upstream side from the place where the water turbine is installed and the second movable guide 17 that guides the flow of the water in a freely variable height are configured. Thus, the rotational force of the water turbine is promoted if it is applied to the drive side of the water turbine from above. In this case, a separate blade may be provided on the water receiving rotation member 7... It is not necessary to apply a water flow to the blade on the drive side in FIG. It becomes possible.
Furthermore, the bottom surface 2 may be provided with a slope guide 18 so that the bottom flow portion passing therethrough is lifted obliquely upward and applied to the drive side of the water receiving rotating member 7.
In the above embodiment and the following embodiments, only one water wheel is shown, but a plurality of water wheels can be arranged on the left and right or front and rear.
Furthermore, in the case of the said embodiment, you may set the fixed axis | shaft 3 in the shape of an inclination axis | shaft so that a drive side may be set to the down side and a return side may be set to the upper side. Moreover, you may make it changeable to any of perpendicular | vertical and inclination. The same applies to the following embodiments.
[0017]
In the embodiment of FIG. 3, resistance due to water flow is not received at the time of return rotation. The foundation block 20 is embedded in the bottom board (or a pile is driven), and a stand 21 is erected on the block 20. Thus, the base plate 23 is pivotally supported on the gantry 21 via the shaft 22. The substrate 23 can be adjusted in angle (including vertical) by the angle adjusting member 24, the long holes 25, and the fastening tool 26.
[0018]
A fixed shaft 28 is erected on the substrate 23 via a base tube 27, and a central rotating body 29 is provided around the fixed shaft 28 so as to be movable up and down. The central rotating body 29 is equipped with a water injection plug 30 for adjusting the buoyancy. If a large amount of water is put into the central rotating body 29, the buoyancy is reduced.
[0019]
On the outer periphery of the central rotating body 29, water receiving rotating members 32 are arranged radially through the arms 31 so that the driving side, which is the left side of the figure, is immersed in the water surface and the other is floated on the water. The water receiving rotation members 32 are thin on the base side so that there is no resistance to water during return rotation. Further, the water receiving / rotating member 32 is a flat plate and has a recess 32a formed in the center thereof so as to reliably capture water. However, the water receiving / rotating member 32 may be a curved plate as shown in FIG. . Further, the lengths of the water receiving rotation members 32 can be adjusted with respect to the arm 31 by the adjustment holes 33 and the fastening device 34. This is effective for setting the water receiving rotary members 32 to float on the water surface completely during the return rotation. The water receiving / rotating member 32 may be a hollow body so that the water receiving / rotating member 32 itself generates buoyancy, and a buoyancy generator such as a polystyrene foam or a hollow body can be added to the water receiving / rotating member 32. Good. 35 is a drive gear, and 36 is a driven gear.
[0020]
In addition, 37 shown with a virtual line is a side stay, and is for fixing an apparatus to the side wall 38 of a river or a waterway. Needless to say, this embodiment and other embodiments can also be installed for oceans such as coastlines in addition to rivers.

[0021]
The embodiment of FIG. 4 shows an example of an additional proposal. In a river (including one without a jetty) in which a river jetty 40 is constructed to prevent breakage and the like, the river has more turbidity than expected. In that case, the water level may change from the normal water level (virtual line) to the solid line state as shown by the arrow, and even more. In response to such a situation, a round (including an ellipse) or square tube (including a triangle) polygonal emergency water feed pipe 41 of concrete, metal, resin, etc. is equipped in an emergency or a stand-alone manner.

In the upstream opening or in the middle of the pipe 41, river water can be sucked up by a pump 42, and the capacity of the pump 42 is 3 to 10 times or more than the assumed speed of river muddy flow. In addition, when making the number of the pipes 41 into a plurality, the speed in the pipe may be lower than that, but it should be higher than the flow speed of the river. However, the speed in the case where the pipe 41 is installed in a place where the muddy flow does not flow may be arbitrary.
[0023]
Examples of installation of the pipe 41 include the solid line jetty 40, the inside or outside of the jetty 40, the inner surface of the river, the middle, the lower level, the corner of the jetty 40, a horizontal member (a roof type or a horizontal shape) 43 In rivers, riverbeds (not shown), etc. The pump 42 can be driven strongly by a water wheel system as in the above embodiment or the following embodiment. Even when the pump 42 is not used, the suction port upstream (or even midway) can be enlarged, or the manifold pipe can be converged so that a large amount of water can be brought into this. In this case, if the pipe for the first time from the opening is not narrowed immediately, but the shape is such that it is gradually narrowed in a tapered shape, the stagnation from the opening becomes smooth.
[0024]
In the embodiment of FIG. 5, a vertical (or inclined) fixed shaft 46 is fixed to the bottom, and a central rotating body 47 is provided so as to be movable up and down around the fixed shaft 46 and an arm around the central rotating body 47.

Yes. The bar 50 is also configured to follow the water level. This embodiment is also applied to a system that circulates with a chain or the like. Without the fixing means such as a fixed shaft, the central rotating body 47 may be a floating body that is swept from the upstream by a wire rope or the like.
[0026]
In the embodiment of FIG. 6, the fixed shaft 52 is inclined and directly placed on a bank (or river bed) 53 that is not a riverbed, and a water receiving rotating member 53 is provided around the fixed shaft 52 so as to be submerged on the drive side.

Is a point. That is, the water receiving rotating member 64 surrounds the inner frame a and the inner frame a using the remaining most of the lower leg portion of one of the ladder frames as a frame scaffold. It consists of a water receiving plate b fixedly attached.
The inner frame a has a stopper 65 such as an angle member fixed to the outer periphery of the central rotating body 63 so that there is almost no resistance with the help of the exclusion guide 66 although it is radially resistant on the drive side and somewhat resistant to the flow on the return side. It is something that falls back and forth.
The water receiving plate b is substantially for receiving a water flow, and these are configured at a very low cost. The water receiving / rotating member 64 is hollow and is itself a buoyant body. However, when the central rotating body 63 is a buoyant body, water may enter. The water receiving rotating member 64 and / or the central rotating body 63 serves as a buoyancy body.
In addition, there may be a plurality of water receiving rotating members 64, as indicated by phantom lines in FIG. Of course, other temporary equipment (such as a walk board, a building frame, and a simple building frame) may be used.

[0059]
The upper part of the viewing water tank 201 is lower than the bridge 200 when not in use. For example, when it becomes dark, the viewing water tank 201 is raised automatically (a solar power source may be used) or manually. At the same time, the vacuum pump is operated, so that the fish 202 in the river are sucked up together with the river water and kept in this state. The viewing water tank 201 may be illuminated by a light 211 and floated.
[0060]
The viewing water tank 201 may be levitated by buoyancy generating means installed on the outer periphery of the water tank 201 so as to be in the river. In this case, the buoyancy generating means may be, for example, a hollow body that introduces / leads air inside. You may combine the said raising / lowering means with this.
[0061]
In the above description, the vacuum pump system is used. However, as shown in FIG. 37, a suction pump 212 used for sucking fish may be provided.
Furthermore, as shown in FIG. 38, an upper water tank 214 made of an orthogonal hexahedron may be attached to the upper end of the viewing water tank 201 and fixed to a bridge or the like by a connecting table 215. The upper water tank 214 is not limited to a square shape, and may be a round pipe or a plurality of pipes.
[0062]
In FIG. 39, a plurality of water quality management pipes 217 are erected, the lower ends of these pipes are in different states, and river water is sucked up by a vacuum pump or the like. As a result, the water quality at each location with different depths can be understood immediately. In this case, a thin pipe other than the monitoring portion at the upper end may be used, and it is not necessary to be transparent.
[0063]
FIG. 40 shows a case where the whole is not made of a transparent resin pipe, but the whole is made of a metal water tank body 219, and only a necessary part thereof is a viewing section 220 made of resin, glass, etc. Then, the water tank main body 219 is made into a square pipe shape. Reference numeral 221 denotes an air vent pipe. In this example, the water tank body 219 may be fixed. In FIG. 41, the water tank body 223 has a triangular prism shape, and other geometric shapes are also planned to be adopted.
[0064]
In the example of FIG. 42, a viewing water tank 225 is erected and a vacuum pump 226 is connected to the water tank 225 so that river water and fish 227... Are pumped. It is what I did.
A first valve 228 is provided in the middle of the water tank 225, a second valve 229 is provided between the water tank 225 and the pump 226, and third and fourth valves 231, 232 are also provided between the bait supply hopper 230 and the water tank 225. Is provided. And from the upper part of the water tank 225, the horizontal viewing water tank 233 is connected in parallel with the bridge 234 and is received by the stay 235. The stay 235 may be liftable.

At the tip of the horizontal viewing water tank 233, a fifth valve 236 is provided, and a water receiving tank 238 provided with a microorganism tank 237 is installed in correspondence with the location where water flowing out from the opening of the tip falls.
[0066]
First, the vacuum pump 226 is driven in a state where the fourth and fifth valves 232 and 236 are closed and the others are inflated, whereby the fish in the viewing water tank 225 and the horizontal viewing water tank 233 are fished together with the river water. 239 ... is sucked up. In this state, the bait is fed from the bait supply hopper 230 as necessary, and then the third valve 231 is opened to feed the bait with the fourth valve 232 closed. After that, the third valve 231 is closed and the fourth valve 232 is opened, so that the food falls into the viewing water tank 225. As a result, the fishes 239 gather at the top of the viewing tank 225 and eat food. When the first valve 228 is opened in a state where the vacuum pump 226 is stopped and water is held, the bait flows down from there, the bait is dispersed, and soot is collected.
[0067]
Then, by opening the fifth valve 236, the jump of the kite can be seen as shown. Since this jump involves water, it can lead to air contamination and water purification. In addition, the microorganism tank 240 may be arranged in the lower end inner periphery or outer periphery position of the viewing water tank 225.
[0068]
In the example of FIG. 43, a fixture 243 is set around the viewing water tank 242, a net or porous microorganism tank 244 is attached to the water at the lower end, and microorganisms are placed in the interior as indicated by the arrow Z. In this case, air may be ejected through the air pipe 245 and the air ejection pipe 246.
[0069]
In the example of FIG. 44, the valve is simply performed by a lid 249 provided at the lower end of the viewing water tank 248, and the lid 249 is opened and closed on the support 250 arranged on the outer periphery of the viewing water tank 248. This is performed by a transmission link 251 and a driving means 252 such as a cylinder which can be moved freely.
[0070]
The example of FIG. 45 shows an apparatus that can take garbage collected in the viewing water tank 254 from above and feed fish (such as carp). The viewing water tank 254 includes a first valve 255 in the middle and a vacuum pump 257 via a second valve 256. A third valve 258 is provided at the upper end of the viewing water tank 254.
[0071]
By operating the vacuum pump 257 with the first valve 255 and the second valve 256 open and the third valve 258 closed, dust collects on the water surface in the viewing water tank 254. These dusts are removed by stopping the pump 257 and opening the third valve 258. At that time, you can feed at the same time or touch the candy.
[0072]
In addition, 259 shown with an imaginary line is an inner surface brush which can remove the deposits on the inner surface of the viewing water tank 254, and an outer peripheral brush may be used.
[0073]
In addition, dust accumulates on the water surface near the lower side of the viewing water tank 254 during tide. In order to eliminate this, the example of FIGS. 46-48 is proposed. 260 is a garbage collector, 261 is a conveyor, and 262 is a garbage collection container. The conveyor 261 is entirely made of a net-like material, and a dust bucket 264... Has been. Coarse garbage is removed, medium and small garbage are scraped up by the conveyor 261, and dirt and the like are scraped up by buckets 264, and dust and dirt around the viewing water tank 254 are removed by this apparatus.
