Description

  The present invention relates to a water turbine apparatus.

  Examples of the conventional technology of the water turbine device include those described in Patent Documents 1 and 2. Patent Document 1 describes a technique in which a water turbine pipe that drops water on an inclined land and a water turbine provided in the middle of the water turbine pipe are arranged. Patent Document 2 describes a technique in which a plurality of water turbines are arranged in multiple stages in the vertical direction.

  There are roughly two types of water turbine devices: a so-called hanging type in which irrigation water is flowed to the lower part of the water wheel and turned, and a so-called upper type in which the irrigation water is dropped from the upper part of the water wheel. The watermill device of Patent Document 2 is a top-down type. The top type can obtain a relatively large amount of electric power because it uses the head of water, and it is expected that more electric power can be obtained if the turbines are arranged in multiple stages in the vertical direction as in Patent Document 2. . Such a water turbine device having a multi-stage water wheel seems to be suitable as a private power generator particularly in a mountainous village.

  In laying a water channel system such as a water pipe on a slope between mountains and supplying water to a water turbine device, the technique of Patent Document 1 requires a tower body of a power generation tower and a relay pipe in the air. There is a problem that the laying cost of the building becomes high.

  The present invention has been created to solve the above-described problems, and an object thereof is to provide a water turbine device that has a simple structure and can reduce manufacturing costs.

  In order to solve the above-mentioned problems, a watermill device of the present invention is constructed on a sloping ground, and an upstream end port is located at a water source above the sloping ground. A housing made of FRP incorporated therein, and a water conduit extending in the vertical direction is formed in the housing, a downstream end of the water supply hose is connected to a lower end of the water conduit, and an upper end of the water conduit is the water supply It is lower than the upstream end of the hose, and water is supplied to the upper water turbine from the upper end of the water conduit.

  Since the upper end of the water conduit is lower than the upstream end of the water supply hose located at the water source, the water flowing into the lower portion of the water conduit through the water supply hose flows upward in the water conduit, and the upper end of the water conduit Is supplied to the upper turbine. According to the water turbine apparatus, the laying operation is extremely easy because it is only necessary to install the water supply hose on the sloping ground with respect to the water supply system from the water source to the housing. Since there is no installation part in the air, it is excellent in assembling on site.

  Further, the watermill device of the present invention is characterized in that a funnel disposed at the upper part of each waterwheel is fixed to the housing, and water dropped from the upper end of the water conduit is supplied to the watermill through the funnel. To do.

  According to the watermill device, water can be efficiently collected by the funnel, and a large electric power can be obtained by increasing the rotational torque of the watermill.

  Moreover, the watermill device of the present invention is characterized in that a fixed floating skimmer is provided in the water source, and an upstream end of the water supply hose is configured as a water surface suction port of the fixed floating skimmer.

  If a water flow meter is provided in the water source, the water turbine device is highly profitable and can easily obtain large electric power without securing and losing water flow. If the water flow quantification device is a quantitative floating skimmer and the upstream end of the water supply hose is configured as a water surface suction port for the quantitative floating skimmer, the construction cost can be reduced and the production cost of the water turbine device can be reduced.

  In the watermill device according to the present invention, the float of the fixed floating skimmer is a poly tank.

  By making the float of the fixed floating skimmer into a poly tank with excellent versatility, the production cost of the water turbine device can be further reduced.

  According to the present invention, with respect to the water supply system from the water source to the housing, it is only necessary to simply install the water supply hose on the sloping ground. Since there are no aerial installation parts, it is easy to assemble in the field and can be installed easily in mountainous villages.

  As shown in FIG. 1 and FIG. 2, the water turbine device 1 is installed on a sloped land S, and an upstream end 2 </ b> A is installed on a flexible water supply hose 2 located in a water source W above the sloped land and a flat ground H below the sloped land. And an FRP housing 3 in which multistage water turbines 31 are built in the vertical direction.

  Examples of the water source W include a pond and a water tank. By providing the fixed floating skimmer 4 in these water sources W, it becomes possible to supply a constant amount of water to the water wheel 31 regardless of the fluctuation of the water level, and stable power can be obtained. As shown in FIG. 3A and FIG. 4, the basic configuration example of the fixed floating skimmer 4 includes a flat plate 5, a poly tank 6 as a float placed on the flat plate 5, and a water supply hose 2.

  The flat plate 5 is, for example, a rectangular resin plate. A plurality of plastic tanks 6 are mounted and fixed on the flat plate 5 by fastening bands 7. A hole for passing the water supply hose 2 is formed in the flat plate 5, and the upstream end 2 </ b> A of the water supply hose 2 is inserted and fixed from below into the hole. The upstream end port 2A functions as a water surface suction port, and may be the end port of the water supply hose 2 or the end port of the suction pipe 8 attached to the end port of the water supply hose 2 as illustrated. Good. By adjusting the filling amount of water in the plastic tank 6, the distance between the water surface and the water surface suction port can be easily adjusted. That is, the amount of water flowing into the water supply hose 2 can be easily adjusted. There may be one water surface inlet or a plurality of water surface inlets as shown.

  Moreover, frequent flow adjustment can be easily handled by covering the water surface suction port with the cap 9. For example, when there are multiple water inlets, open all the water inlets when you want to secure a large amount of water, and when you want to reduce the amount of water to some extent, close some of the water inlets with caps 9 and supply completely water. When not, the cap 9 may be put on all the water surface inlets. In addition, vertical bar-shaped balancers 20 are appropriately provided at the four corners of the flat plate 5 as a bracing device for the fixed-quantity floating skimmer 4.

  Further, a dust collecting net 10 may be provided as shown in FIG. 3B for the purpose of preventing dust (falling leaves, etc.) from entering the water surface inlet. The dust collection net 10 is provided so as to cover the fixed floating skimmer 4. A plastic tank 11 is attached as a float so that the garbage collection net 10 can also respond to fluctuations in the water level.

  When the water source W is a water storage tank, for example, as shown in FIG. 3C, a water storage tank is provided beside the waterway or the river 12 and a gate 13 is provided in the waterway or the river 12, so that the amount of water can be easily obtained. It can be sent to the water tank after adjustment. The water storage tank can be easily manufactured by making it from FRP. Moreover, when providing a water storage tank without using the waterway or the river 12, the structure which recirculates the water used with the water turbine 31 to the water storage tank with the pumping pump 14 can be employ | adopted as shown in FIG. . Furthermore, the water used in the water turbine 31 can be used for another water turbine device, for example, a hung-type water turbine device 41 as shown in FIG.

  A bellows-like hose can be suitably used as the water supply hose 2. The water supply hose 2 is laid along the slope S as shown in FIG. 1, and the downstream end 2B is connected to the lower part of the housing 3 (specifically, the lower end of the water conduit 18 as described later). Since the water supply hose 2 is merely installed on the inclined land S and the flat ground H over almost the entire length, the laying operation is extremely easy. If the downstream end 2B of the water supply hose 2 is connected to the upper part of the housing 3 from the middle of the slope S, the water supply hose 2 will be installed in the air, and it will take time for installation work, and it will be solid with measures such as strong wind measures. However, according to the present invention, since the aerial installation is not required, the water turbine device 1 is excellent in assembling on-site.

  As shown in FIG. 5, in the housing 3, a water turbine 31 is arranged as a so-called top-end type in which water is dropped from the upper part of the water turbine 31 and turned. As shown in FIG. 6, the housing 3 has a cross shape in plan view, and water turbines 31 are arranged in multiple stages in the vertical direction inside each of the four extending portions 15 as shown in FIG. 5. A funnel 16 disposed on the top of each water turbine 31 is fixed to the housing 3. Water that has dropped from the upper end of a water conduit 18 to be described later is collected by the funnel 16 and then supplied from the funnel port 17 to the water turbine 31. The water dropped from the water turbine 31 is collected by the funnel 16 located below the water turbine 31 and sequentially supplied to the lower water turbine 31 by dropping. The funnel 16 can also be easily manufactured by FRP.

  In the housing 3, a water conduit 18 extending in the vertical direction is formed. As shown in FIG. 6, the water conduit 18 is integrally formed as a space with a rectangular closed cross section in a plan view on the tip wall of each extending portion 15. As described above, the downstream end 2B of the water supply hose 2 is connected to the lower end of the water conduit 18. The upper end of the water conduit 18 is lower than the upstream end 2 </ b> A of the water supply hose 2. An upper end opening 19 that opens toward the inside of the housing 3 is formed at the upper end of the water conduit 18.

  As described above, since the upper end of the water conduit 18 is lower than the upstream end 2A of the water supply hose 2 located at the water source W, the water flowing into the lower portion of the water conduit 18 through the water supply hose 2 passes through the water conduit 18. It flows upward and is supplied to the uppermost water turbine 31 by dropping from the upper end opening 19.

  In addition, although the rotational force of each water turbine 31 arranged in multiple stages in the vertical direction may be independently taken out and generated by each power generator, as shown in FIG. A configuration may be adopted in which an annular endless member 33 such as a chain or a belt is hung around a sprocket, a pulley, or the like attached to the rotating shaft 32, and the rotational force is taken out from one rotating shaft 32 to generate power with one generator.

  In the above, the suitable example of the watermill apparatus 1 of this invention was demonstrated. As an example of the structure of the water wheel 31 itself, as shown in FIGS. 7 and 8, a structure in which water receiving buckets 35 are fixed to both side surfaces of the ring plate 34 by bolts, nuts, and the like. The ring plate 34 and the water receiving bucket 35 are preferably made of FRP, and can be made of a resin containing a carbon fiber in addition to a resin containing a glass mat.

  FIGS. 9-11 is explanatory drawing of the 1st modification of the structure of a water turbine. The water wheel 41 also has a structure in which water receiving buckets 43 are fixed to both side surfaces of the ring plate 42 by bolts, nuts, and the like. As shown in FIG. 10, the water receiving bucket 43 is formed in a flat triangular dust removal shape when viewed from the side, and the side facing the radially outward direction of the ring plate 42 is a water outlet, as can be seen from FIG. 11. It is open.

  FIG. 12 is an explanatory diagram of a second modification of the structure of the water wheel. The water wheel 51 has a structure in which ring plates 52 each having a plurality of water receiving bucket half pieces 53 formed on the respective edges are overlapped with each other, and the edge portions of the water receiving bucket half pieces 53 are attached to each other to form one water receiving bucket. Configure. The joints at the edges of the water receiving bucket halves 53 are closed by, for example, FRP spray painting.

  FIG. 13 is an explanatory diagram of a third modification of the structure of the water wheel. The water turbine 61 is integrally formed with a pair of ring plates 62 in which a plurality of convex strips 63 extending from the outer edge toward the axial center on the inner surface are formed in the circumferential direction, and mounting flanges 65 on both sides. It is a structure provided with a water receiving bucket 64 that is fixed between the ring plates 62 by attaching the flange 65 to the ridge 63. A concave groove having a rectangular cross section is formed on the outer side surface of the annular plate 62, and the protruding line portion 63 is a portion that forms an outline of the concave groove. The water receiving bucket 64 is fastened and fixed by a bolt 66 and a nut 67 with the mounting flange 65 applied to one side surface of the ridge 63.

  In each of the water turbines 31, 41, 51, 61 shown above, the wheel plate and the water receiving bucket can be easily manufactured by FRP, and the manufacturing cost can be reduced.

  Moreover, you may provide an air bleeding valve suitably in the middle of the water supply hose 2 or the water conduit 18.
