Description

  The present invention relates to a power generator and a pump.

  Conventional power generation devices have mainly used fossil fuels or the like to convert them into electrical energy. However, resources such as fossil fuels are limited, and carbon dioxide, which causes global warming, or nitrogen oxides, which causes photochemical smog and acid rain, is generated, leading to deterioration of the global environment.

  Under such circumstances, various techniques for obtaining electric energy from fluid energy such as hydraulic power and wind power have been developed from the viewpoint of protecting the global environment.

  Patent Literature 1 and Patent Literature 2 disclose a wind-hydraulic power generation apparatus in which a plurality of rotor blades are installed around a rotating shaft. A plurality of rotor blades receive wind and hydraulic power, and the rotor blades revolve around the rotation axis. Since the rotary blade and the rotary shaft are connected via a connecting member, the rotary shaft rotates. The rotational energy of the rotating shaft is converted into electric energy and taken out.

FIG.

(Embodiment 1)
The power generator according to Embodiment 1 will be described with reference to the drawings. As shown in FIG. 1 to FIG. 3, the power generation device 1 includes a fixed shaft 20a, 20b partially having fixed shaft gears 21a, 21b installed in a case 10, and blade rotation gears 40a, 40b. Half-rotary blade rotating shafts 32a and 32b, to which the half-rotating blades 30a and 30b are fixed and the planetary gears 31a and 31b are fixed, respectively, the fixed-shaft gear 21a and the blade-turning gear 40a, and the fixed-shaft gear 21b and the blade-turning The chain 35a, 35b connecting the gears 40b, the output shafts 50a, 50b to which the output gears 51a, 51b are fixed, and the energy conversion devices 70a, 70b.

  The case 10 is composed of two disc-shaped side plates and a flat plate connecting a part of both side plates. The case 10 is provided with an attachment member 11 that is fixed to a drainage channel or a pier.

  Fixed shafts 20a and 20b are fixed to the center portions of both side plates of the case 10, respectively. The fixed shafts 20a and 20b are arranged symmetrically apart from each other on the same axis. The fixed shafts 20a and 20b are respectively fixed to the side plates of the case 10 by fixing members 22a and 22b such as half-moon keys. The fixed shafts 20a and 20b projecting inward from the side plate of the case 10 are sliding surfaces having no unevenness on the side plate side of the case 10, and fixed shaft gears on which the chains 35a and 35b can be suspended inside the case 10 21a and 21b are arranged.

  The half rotor blades 30a and 30b are rectangular flat plates, and the dimensions thereof are the same. Cylindrical half-rotating blade rotating shafts 32a and 32b are fixed to the central portions of the half-rotating blades 30a and 30b, respectively. The shape of the half rotor blades 30a and 30b is not limited to a rectangular flat plate.

  A blade turning gear 40a and a planetary gear 31a are arranged in this order from one end of the half rotor blade rotating shaft 32a protruding from the half rotor 30a. A blade turning gear 40b is disposed at the other end of the half-rotating blade rotating shaft 32a. The half rotary blade rotating shaft 32a and the planetary gear 31a are fixed by a fixing member (not shown) or the like. Further, the half-rotating blade rotating shaft 32a, the blade turning gear 40a, and the blade turning gear 40b are connected to each other through sliding bearings 42a and 42b provided on the blade turning gears 40a and 40b, respectively. The blade rotating shaft 32a is slidably supported by the blade turning gears 40a and 40b.

  Similarly to the above, the blade turning gear 40b and the planetary gear 31b are arranged in order from the end side at one end of the half-rotating blade rotating shaft 32b. A blade turning gear 40a is disposed at the other end of the half-rotating blade rotating shaft 32b. The half rotary blade rotating shaft 32b and the planetary gear 31b are fixed by a fixing member (not shown) or the like. The half-rotating blade rotating shaft 32b, the blade turning gear 40b, and the blade turning gear 40a are connected to each other through sliding bearings 42c and 42d provided on the blade turning gears 40b and 40a, respectively. The blade rotation shaft 32b is slidably supported by the blade rotation gears 40b and 40a.

  The two planetary gears 31a and 31b have the same structure and have gears around which the chains 35a and 35b can be suspended. The chain 35a is suspended from the planetary gear 31a and the fixed shaft gear 21a. A chain 35b is suspended from the planetary gear 31b and the fixed shaft gear 21b. The number of teeth of the planetary gears 31a and 31b is twice the number of teeth of the fixed shaft gears 21a and 21b formed on the fixed shafts 20a and 20b.

  The blade turning gears 40a and 40b are disk-shaped gears each having a circular hole formed at the center thereof, and the sliding surfaces of the fixed shafts 20a and 20b are inserted into the holes, respectively. The blade turning gears 40a and 40b and the fixed shafts 20a and 20b are slidably arranged via bearings 41a and 41b. The blade turning gears 40a and 40b are respectively connected to the fixed shafts 20a and 20b. And can be rotated.

  FIG. 4 shows the arrangement relationship of the half-rotating blades 30a and 30b, the half-rotating blade rotating shafts 32a and 32b, the planetary gears 31a and 31b, and the fixed shafts 20a and 20b as seen in the BB ′ direction in FIG. The semi-rotary blade rotating shafts 32a and 32b are arranged to face each other with the fixed shafts 20a and 20b as the center. In other words, the half rotor blade rotating shaft 32a, the fixed shafts 20a and 20b, and the half rotor blade rotating shaft 32b are arranged on the same straight line. For this reason, the half rotary blade 30a and the half rotary blade 30b are also arranged on the same straight line with the fixed shafts 20a and 20b as the center. More specifically, the half rotor blade rotating shaft 32a, the fixed shafts 20a and 20b, and the half rotor blade rotating shaft 32b are located on the same plane. The angle formed by the half rotary blade 30a and the half rotary blade 30b is substantially a right angle. This angle is maintained even during operation, as will be described later.

  In the half rotor blades 30a and 30b, the length L1 from the half rotor blade rotation shafts 32a and 32b to the end is longer than the length L2 from the half rotor blade rotation shafts 32a and 32b to the fixed shafts 20a and 20b.

  A rotating plate 60a is disposed between the half-rotating blades 30a and 30b and the planetary gear 31a, and a rotating plate 60b is disposed between the half-rotating blades 30a and 30b and the planetary gear 31b. The rotary plates 60a and 60b are slidable with respect to the case 10, and both end portions of the half rotary blade rotary shafts 32a and 32b are slidably inserted.

  In the present embodiment, both ends of the rotary shafts 32a and 32b are slidably attached to the blade turning gears 40a and 40b, but the rotary plates 60a and 60b have sufficient strength. In the case where the action of the power generation device 1 described later can be achieved, the ends of the half rotary blade rotating shafts 32a, 32b on the side where the planetary gears 31a, 31b are not fixed are the blade rotating gears 40a, 40b. It may not be attached to.

  The rotary plates 60a and 60b mainly prevent water from entering the inside of the case 10 and prevent inoperability due to clogging of the gears and the like. When there is no danger of clogging, the rotary plate 60a , 60b may not be provided.

  The output gears 51a and 51b are arranged so as to mesh with the blade turning gears 40a and 40b. Output shafts 50a and 50b are fixed to the centers of the output gears 51a and 51b by fixing members 53a and 53b, respectively. The output shafts 50a and 50b are slidable through bearings 52a and 52b, respectively. Is pivotally supported.

  The end portions of the output shafts 50a and 50b protrude from the side plates of the case 10 and are connected to the energy conversion devices 70a and 70b. The energy conversion devices 70a and 70b are devices that combine a magnet, a coil, and the like to generate power by the action of magnetic force.

  Then, with reference to FIGS. 5-7, the effect | action of the electric power generating apparatus 1 is demonstrated.

  First, in the state of FIG. 5A, when a fluid flow is received in the left direction on the paper surface, a flow force F mainly acts on the semi-rotary blade 30a. In response to this flow force F, the semi-rotary blade 30a is pushed to the left in the drawing.

  Then, as shown in FIG. 5 (B), the planetary gear 31a is fixed to the half-rotating blade rotating shaft 32a to which the half-rotating blade 30a is fixed, and the blade turning gears 40a and 40b are slidable. Therefore, the half rotor blade 30a rotates clockwise in the drawing. Since the planetary gear 31a is connected to the fixed shaft gear 21a via the chain 35a, the planetary gear 31a rotates (revolves) around the fixed shafts 20a and 20b while rotating clockwise in the drawing. Furthermore, the blade swirl gears 40a and 40b also rotate clockwise in the drawing with the fixed shafts 20a and 20b as fulcrums.

  Since the half-rotating blade rotating shaft 32b is similarly connected to the blade-turning gear 40b, the half-rotating blade 30b and the planetary gear 31b move in the same manner as described above as the blade-turning gear 40b rotates.

  When the above rotation proceeds, as shown in FIGS. 6A and 6B, the semi-rotary blade 30b is positioned on the upstream side of the flow. Then, the flow force F mainly acts on the half rotor blade 30b. Then, rotation continues in the same manner as described above.

  Then, as shown in FIG. 7, when the blade turning gears 40a and 40b each rotate by half rotation (180 °), the two half-rotating blades 30a and 30b are just replaced from the state shown in FIG. It becomes. The half rotor blades 30a and 30b are each rotated 90 °.

  Accordingly, when the blade turning gears 40a and 40b rotate once (360 °), the half-rotating blades 30a and 30b return to the arrangement shown in FIG. 5A, respectively. Thus, when the blade turning gears 40a and 40b rotate by one rotation (360 °), the half-rotating blades 30a and 30b rotate by a half rotation (180 °).

  In this way, the semi-rotary blades 30a and 30b, the semi-rotary blade rotation shafts 32a and 32b, the planetary gears 31a and 31b, and the blade swirling gears 40a and 40b continue to receive the fluid flow, respectively. Keep moving.

  As described above, since the blade turning gears 40a and 40b rotate, the output gears 51a and 51b meshing with these also rotate. As the output gears 51a and 51b rotate, the output shafts 50a and 50b also rotate.

  The energy conversion devices 70a and 70b connected to the output shafts 50a and 50b convert the rotational energy of the output shafts 50a and 50b into electric energy and generate electric power.

  FIG. 8 schematically shows the outer locus of the half rotor blades 30a and 30b and the locus of the semi rotor blades 32a and 32b. Since the number of teeth of the planetary gears 31a and 31b is twice the number of teeth of the gears of the fixed shafts 20a and 20, the two half-rotating blades 30a and 30b rotate half-turn around the fixed shafts 20a and 20b, respectively. Since the two half-rotating blades 30a and 30b rotate while maintaining their right angles, the occupied space required to move the half-rotating blade rotating shafts 32a and 32b is small. In addition, since the three dimensions of the power generator 1 can be designed to be about 1.5 times the width and length of the half rotor blades 30a and 30b, a small power generator 1 can be realized.

  Also, as shown in FIG. 4, the vertical length L1 from the end of the half rotor blades 30a, 30b to the half rotor blade rotation shafts 32a, 32b is from the half rotor blade rotation shafts 32a, 32b to the fixed shaft 20a, Since it is formed longer than the length L2 up to 20b, the ratio of the area occupied by the half-rotating blades 30a, 30b is high in the pressure receiving area of the fluid acting on the power generation device 1, and the rotating shaft of the rotating half-rotating blade is swiveled. The rotational centers of 32a and 32b are theoretically the rotational cores of the semi-rotary blades 30a and 30b, so that the rotational efficiency is high. For this reason, even if it is small, the rotation efficiency is high and the electric power generating apparatus 1 which exhibits favorable electric power generation capability is implement | achieved.

  As described above, since the power generation device 1 is small and has a high rotational efficiency, the power generation device 1 can be installed in a place where various fluid flows exist to generate power. For example, it is installed in a channel where factory drainage flows, generates electricity, installs in a culvert or irrigation channel, etc., generates electricity by installing on a river pier or quay, etc. It is possible to supply power to the street light.

  Moreover, you may install the electric power generating apparatus 1 in the location with the flow of gas etc. other than the installation to the location with the flow of liquids, such as water. For example, the exhaust duct of a factory, the location where waste steam is spouting, etc. are mentioned.

  Moreover, since the electric power generating apparatus 1 is small, there exists an advantage that a freedom degree is high also about the aspect of installation. Since it is small in size, it is easy to install a plurality of power generation devices 1 at locations where fluid flows. In the case where a plurality of power generation devices 1 are installed in narrow flow paths with fluid flow, a large number of power generation devices 1 can be installed in series in the fluid flow direction. Moreover, when installing in a wide flow path etc., you may install so that a flow may be crossed.

  Further, the power generator 1 may be installed so that the half-rotating blade rotating shafts 32a, 32b are horizontal, or may be used by installing the semi-rotating blade rotating shafts 32a, 32b vertically.

(Embodiment 2)
Next, the power generation device 2 according to Embodiment 2 will be described. As shown in FIGS. 9 to 11, the power generation device 2 is installed in the case 10 and has fixed shafts 20a and 20b partially having fixed shaft gears 21a and 21b, blade turning gears 40a and 40b, Half-rotary blade rotating shafts 32a and 32b, to which the half-rotating blades 30a and 30b are fixed and the planetary gears 31a and 31b are fixed, respectively, the fixed-shaft gear 21a and the blade-turning gear 40a, and the fixed-shaft gear 21b and the blade-turning Chains 35a and 35b for connecting the gears 40b, the rotating shaft 55 to which the gears 54a and 54b are fixed, the output shaft 50b to which the output gear 51b is fixed, the energy conversion device 70, the power supply line 71, the lamp 72, a cover 73, and a gap member 74.

  The power generation device 2 is different from the power generation device 1 of the first embodiment mainly in that it includes a cover 73 and a gap member 74, and other configurations are the same as those of the power generation device 1 according to the first embodiment. Description is omitted.

  Note that the arrangement of the chains 35a, 35b and the like is different from that of the first embodiment. Specifically, the fixed shaft gears 21a, 21b of the fixed shafts 20a, 20b are positioned opposite to the sliding surfaces, and the chains 35a, 35b, the planetary gears 31a, 31b are positioned on the side plate side of the case 10, and the blades The turning gears 40 a and 40 b are located inside the case 10.

  The output gear 51b is configured to rotate by rotation of the blade turning gear 40b via the gear 54b. Then, the energy conversion device 70 generates electricity by the rotation of the output shaft 50b, and the generated electricity is conducted through the power supply line 71 to cause the lamp 72 to emit light.

  The power generator 2 has a cover 73 along the maximum outer peripheral locus of the rotation of the half rotor blades 30a and 30b shown in FIG. As can be seen from FIG. 10, the tip of the cover 73 on the fluid inflow side is higher than the tip of the fluid outflow side by about h. When the cover 73 has a small amount of water flowing through the U-shaped groove, the flowing water flows in a state of being thinly attached to the bottom of the U-shaped groove. When the amount of flowing water is small, the inflow side flowing water is blocked to create a drop, and the flowing water pressure is applied to the half rotor blades 30a and 30b.

  Furthermore, the power generation device 2 includes a gap member 74 that fills a gap between the cover 73 and the case 10 and the U-shaped groove. The gap member 74 fills the gap with the U-shaped groove, thereby allowing the water flowing through the U-shaped groove to enter the cover 73 without waste so that the flowing water pressure is applied to the half-rotating blades 30a and 30b.

  FIG. 12 shows a state where the power generator 2 is installed in the U-shaped groove 75. The dimensions of the case 10, the cover 73, the half rotor blades 30 a and 30 b, etc. constituting the power generation device 2 are appropriately designed according to the dimension of the U-shaped groove 75 to be installed. A gap between the case 10, the cover 73, etc. and the U-shaped groove 75 is filled with a gap member 74. The gap member 74 may have any shape and material as long as the gap 73 between the cover 73 and the case 10 and the U-shaped groove is filled and water flowing through the U-shaped groove can flow into the cover 73. .

  FIG. 13 shows a state in which the semi-rotary blades 30a and 30b are continuously rotated by the water flowing through the U-shaped groove 75. When water is blocked by the cover 73 and the volume of water increases and exceeds the tip of the cover 73 on the inflow side, flowing water pressure is applied to the half-rotary blade 30b. Since the water volume increases and there is a drop, the half-rotating blade 30b rotates efficiently because the half-rotating blade 30b is subjected to water gravity in addition to the force in the flow direction of water.

  Then, when the half-rotating blade 30b passes through the outflow side tip of the cover 73 and the flowing water pressure applied to the half-rotating blade 30b is released, the half-rotating blade 30a reaches the inflow side tip of the cover 73, and the half-rotating blade 30a. In the same manner as above, flowing water pressure is applied. In this way, the semi-rotary blades 30a and 30b continue to rotate continuously and efficiently.

  Further, since the gap between the U-shaped groove 75 and the cover 73 and the case 10 is filled with the gap member 74, the water flowing through the U-shaped groove 75 flows into the cover 73 without leakage. Thus, even if it is a U-shaped groove where a small amount of water flows by the cover 73 and the gap | interval member 74, the water can be utilized without wasting and making it act on the half rotary blades 30a and 30b. Thereby, it is possible to generate electric power efficiently and cause the lamp 72 to emit light.

  In addition, although the form provided with the lamp | ramp 72 was demonstrated above, as shown in FIG. 11, the output gear 51a and the output shaft 50a are rotated by the conversion gear 56 fixed to the rotating shaft 55, and the cover of case 10 is covered. 12 may be opened and the energy conversion device 70 may be installed above to generate power.

(Embodiment 3)
Subsequently, a pump according to Embodiment 3 will be described. FIG. 14 shows a cross section of the pump 3, and the configuration is an application of the power generator 1 described above as it is. The output shafts 50a and 50b described in the power generation device 1 are input shafts 80a and 80b, and the output gears 51a and 51b are input gears 81a and 81b. The input shafts 80a and 80b have the same configuration as the output shafts 50a and 50b, and the input gears 81a and 81b have the same configuration as the output gears 51a and 51b.

  Then, rotational drive devices 90a and 90b for rotating the input shafts 80a and 80b are arranged. Known devices such as a motor that converts electrical energy into rotational force can be used as the rotation drive devices 90a and 90b. Other configurations are the same as the configuration of the power generation apparatus 1 described in the first embodiment, and thus the description thereof is omitted.

  By rotationally driving the rotation driving devices 90a and 90b, the input shafts 80a and 80b and the input gears 81a and 81b fixed thereto are rotated. Since the rotation of the input gears 81a and 81b causes the blade rotation gears 40a and 40b to rotate, the half rotary blade rotation shafts 32a and 32b connected to the blade rotation gears 40a and 40b pass around the fixed shafts 20a and 20b. Turn. Since the planetary gears 31a and 31b and the half-rotating blades 30a and 30b are fixed to the half-rotating blade rotating shafts 32a and 32b, the planetary gears 31a and 31b pass around the fixed shafts 20a and 20b via the chains 35a and 35b. While turning, the semi-rotary blades 30a and 30b revolve around the fixed shafts 20a and 20b while rotating. In addition, since the movement of each element is the same as that of Embodiment 1, description is abbreviate | omitted.

  Since the pump 3 is as small as the power generation apparatus 1 described in the first embodiment, the installation mode has a high degree of freedom and can be installed in various places. In addition, since the ratio of the area occupied by the semi-rotary blades 30a and 30b in the pump 3 is high, fluid or the like can be delivered efficiently. For example, it can be effectively used for discharging waste water remaining in a narrow flow path.
