(D) Fourth embodiment (see FIGS. 12 to 14)
FIG. 12 is a plan view showing a use state of the power generation device using the water flow of the bypass river provided in the river according to the fourth embodiment of the present invention, and FIG. 13 relates to the fourth embodiment of the present invention. It is a sectional side view which shows the use condition of an electric power generating apparatus. FIG. 14 is an enlarged cross-sectional view showing an XIV portion of FIG.

First, there is a river 101, and the river 101 is provided with a bypass river 103. That is, a bypass river intake 105 is provided upstream of the river 101 (right side in FIG. 12), and a bypass river drain 107 is provided downstream of the river 101 (left side in FIG. 12). It has been. Between the bypass river intake 105 and the bypass river drain 107 is the bypass river 103.

  A switching valve 109 is provided at a position slightly downstream of the river 101 from the bypass river intake 105. When the switching valve 109 is open, the water flow passes through both the river 101 and the bypass river 103 from the upstream side toward the downstream side. On the other hand, when the switching valve 109 is closed, the water flow only flows through the bypass river 103.

A power generation device 111 is installed in the bypass river 103. The power generator 111 includes a running water pipe fitting 113. The water pipe fitting 113 is fixed to the riverbed 117 by fixing bases 115 and 116. The fixing table 115 is installed in a state where it is buried in the water of the bypass river 103 and includes a through hole 115 a for attaching the water pipe fitting 113. On the other hand, the fixed base 116 is installed in a state of being extended higher than the fixed base 115, and the width thereof is the same as the width of the bypass river 103. An open / close valve 119 is provided on the upper side of the fixed base 116 (upper side in FIG. 13). Further, the fixing base 116 is provided with a through hole 116a for attaching the running water pipe fitting 113.

As a result, the water flow passes only through the outlet 123. At the same time, a difference in height occurs between the upstream side and the downstream side of the opening / closing valve 119, compared to the state where the opening / closing valve 119 is opened, and the flow velocity can be further increased.

  In addition, the power generation device 111 uses the flowing water pipe fitting 113 described above, the flowing water pipe 127 disposed in the water of the bypass river 103, and the water flow 129 flowing inside the flowing water pipe 127 to rotate energy. Energy generating means 131 for generating the electric energy, and a generator 133 as electric energy generating means for converting the rotational energy generated by the energy generating means 131 into electric energy. The leading end 125 of the water pipe 127 is located on the upstream side of the bypass river 103. The water pipe 127 is also fixed to the riverbed 117 by a fixture 134. The flowing water pipe 127 is fixed through a through hole 134 a provided in the fixture 134.

A strainer 135 is provided at the distal end portion 125 of the water flow tube 127 so that only water outside the water flow tube 127 is taken into the water flow tube 127 and foreign matter such as earth and sand is prevented from flowing into the drainage tube 127. . As described above, the water pipe fitting 113 is provided at the rear end portion 136 of the water pipe 127. As shown in FIG. 13, the water pipe fitting 113 is configured by including a guide tube 137 that penetrates the through holes 115 a and 116 a and a water pipe support 139 having a lattice-like water flow structure as an example. Has been. The flowing water pipe support 139 is a member for supporting the rear end portion 136 of the flowing water pipe 127 and fixing it to the guide tube 137. In the present embodiment, the flowing water pipe support 139 has a shade-like external shape as an example, and has a large mesh. A support with a water flow structure is used.

The energy generating means 131 includes a hydraulic pump 143 provided with a propeller 141 rotated by a water flow 129 flowing in the flowing water pipe 127 as an input shaft, and a hydraulic pressure provided on the ground and rotated by pressure oil supplied from the hydraulic pump 143. The motor 145 is provided. A plurality of the hydraulic pumps 143 are installed at appropriate intervals so as to be positioned at the center of the drain pipe 127 by the support rod 144.

  As an example, the hydraulic pump 143 has a streamlined external shape, and the propeller 141 is disposed so as to face the distal end portion 125 side of the flowing water pipe 127. The hydraulic pump 143 is supplied with pressure oil pumped from the hydraulic pump 143 to the ground hydraulic motor 145, and returns the hydraulic oil discharged from the hydraulic motor 145 to the hydraulic pump 143 again. Is connected.

  The hydraulic path 147 includes a supply path 147A for supplying pressure oil to the hydraulic motor 145 and a return path 147B for returning the pressure oil discharged from the hydraulic motor 145 to the hydraulic pump 143. The supply path 147A and the return path 147B fed out from each hydraulic pump 143 are joined to one path on the way, and then connected to the ground hydraulic motor 145.

Next, the power generation method using the flowing water pressure of the present embodiment, which is executed by using the power generation device 111 using the flowing water pressure, will be described. The power generation method using the flowing water pressure according to the present embodiment is basically configured by including (1) a water flow forming step, (2) a rotational energy generating step, and (3) an electric energy generating step. ing.

(1) Water Flow Formation Step The water flow formation step is a step of forming a water flow 129 in the water flow pipe 127 connected to the outflow port 123 using the energy of the water directly flowing out from the outflow port 123. In the present embodiment, the width of the fixed base 116 provided with the outlet 123 is the same as the width of the bypass river 103, and the height of the fixed base 116 is the same as the depth of the bypass river 103. Therefore, if the opening / closing valve 119 provided at the upper part of the fixed base 116 is closed, the water flow that has passed through the opening / closing valve is blocked, and the water flow passes only through the water flow pipe 127. .

Therefore, the difference in the water level at the fixed base 116 becomes larger than when the opening / closing valve 119 is opened and a water flow passes through both the opening / closing valve and the flowing water pipe 127. That is, the water level on the upstream side of the fixed table 116 is increased, and the water level on the downstream side of the fixed table 116 is decreased. Therefore, due to this water level difference, the water on the upstream side of the fixed base 116 flows into the flow pipe 127 vigorously from the lattice-like mesh of the strainer 135 provided at the distal end portion 125 of the flow pipe 127 and flows downstream. It flows to the side. As a result, the water flow 129 is generated.

In addition, the water pipe 127 is attached to the outlet 123 by a water pipe fitting 113, and the water pipe 127 is supported on a portion of the water pipe fitting 113 exposed to the upstream side of the fixed base 116. A water pipe support 139 having a grid-like water flow structure is provided. Therefore, water also flows from the grid-like water flow structure of the water flow pipe support 139 to the downstream side of the fixed base 116, and negative pressure is generated on the rear end portion 136 side of the water flow pipe 127 by the momentum of the water. Thus, a suction force that causes water to flow into the water flow pipe 127 is generated, and the water flow 129 generated in the water flow pipe 127 can be made stronger.

In addition, foreign matter such as earth and sand is simultaneously sucked in when the water flows into the water pipe 127 and the water pipe fitting 113, but the strainer 135 is provided at the distal end portion 125 of the water pipe 127. Since the water pipe support 139 having a lattice-like water flow structure is provided at the tip of the water pipe fitting 113 on the side of the water pipe 127, water and foreign substances are provided by the strainer 135 and the water pipe support 139. Are separated, and only water flows into the water pipe 127 and the water pipe fitting 113.

(2) Rotational energy generation process The rotational energy generation process is a process of generating rotational energy using the water flow 129 formed in the water flow pipe 127. In other words, in the present embodiment, the energy generating means 131 is configured by including the hydraulic pump 143 and the hydraulic motor 145, so that the hydraulic pump 143 disposed in the flowing water pipe 127 flows in the flowing water pipe 127. It operates by receiving a driving force from the propeller 141 rotated by the water flow 129.

When the hydraulic pump 143 starts operation, hydraulic pressure is generated, and the hydraulic pressure is supplied to the ground hydraulic motor 145 through the supply path 147A of the hydraulic path 147. In response to the supply of the hydraulic pressure, the hydraulic motor 145 rotates and rotational energy is generated. The hydraulic pressure used for the rotation of the hydraulic motor 145 is sent again to the hydraulic pump 143 through the return path 147B of the hydraulic path 147 and circulated and used.

(3) Electric energy generation process The electric energy generation process is a process of generating electric energy using the generated rotational energy. That is, in the present embodiment, rotational energy is generated by the hydraulic motor 145 as described above, and therefore, the generator 133 is driven using the rotation of the output shaft of the hydraulic motor 145 to generate electrical energy. Electricity generated by the generator 133 is transmitted to a power transmission line (not shown) through a power transmission line (not shown).

  Thus, according to the present embodiment, power generation can be easily performed by installing the power generation device 111 in the bypass river 103 that bypasses the river 101.

Through holes 234a and 234a are respectively provided in the fixtures 234 and 234 slidably attached to the guides 209 and 209 installed on the flange 203. The flowing water pipe 225 is attached through the through holes 234a and 234a.

A strainer 235 is provided at the distal end portion 223 of the water flow pipe 225 so that only water outside the water flow pipe 225 is taken into the water flow pipe 225 and foreign matter such as earth and sand is prevented from flowing into the water flow pipe 225. . As described above, the water pipe fitting 207 is provided at the rear end 227 of the water pipe 225. As shown in FIG. 14, the water pipe fitting 207 is configured by including a guide tube 237 inserted into the outlet 215 and a water pipe support 239 having a lattice-like water flow structure as an example. Has been. The flowing water pipe support 239 has, for example, the same configuration as that described in the fourth embodiment.

The energy generating means 231 is provided on the ground with the above-described hydraulic pump 243 provided with a propeller 241 that rotates by the water flow 229 flowing in the water flow pipe 225, and rotated by the pressure oil supplied from the hydraulic pump 243. The hydraulic motor 245 is configured to be configured. A plurality of the hydraulic pumps 243 are installed at an appropriate interval so as to be positioned at the center of the water flow pipe 225 by the support rod 244.

As an example, the hydraulic pump 243 has a streamlined outer shape, and the propeller 241 is disposed so as to face the distal end 223 side of the water flow pipe 225. The hydraulic pump 243 is supplied with pressure oil pumped from the hydraulic pump 243 to the ground hydraulic motor 245, and a hydraulic path 247 for returning the pressure oil discharged from the hydraulic motor 245 to the hydraulic pump 243 again.

  The hydraulic path 247 includes a supply path 247A for supplying pressure oil to the hydraulic motor 245 and a return path 247B for returning the pressure oil discharged from the hydraulic motor 245 to the hydraulic pump 243. The supply path 247A and the return path 247B fed out from each hydraulic pump 243 are joined to one path in the middle, and then connected to the ground hydraulic motor 245.

Next, the power generation method using the flowing water pressure of the present embodiment, which is executed by using the power generation device 205 using the flowing water pressure, will be described. The power generation method using the flowing water pressure according to the present embodiment is basically configured by including (1) a water flow forming step, (2) a rotational energy generating step, and (3) an electric energy generating step. ing.

(1) Water Flow Formation Step The water flow formation step is a step of forming a water flow 229 in the water flow pipe 225 connected to the outflow port 215 using the energy of the water that flows out directly from the outflow port 215. In the present embodiment, the width of the fixture 213 provided with the outflow port 215 is the same as the width of the river 201, and the height is substantially the same as the depth of the river 201. Therefore, if the power generator main body 206 is installed on the riverbed 221, the water flow of the river 201 is blocked by the fixture 213 and passes through the outlet 215.

For this reason, a difference in water level occurs with the fixture 213 as a boundary. That is, the water level on the upstream side of the fixture 213 is increased, and the water level on the downstream side of the fixture 213 is decreased. Therefore, due to the difference in water level, the water on the upstream side of the fitting 213 flows into the drain pipe vigorously from the lattice-like mesh of the strainer 235 provided at the distal end portion 223 of the water flow pipe 225 and flows downstream.

Therefore, water also flows downstream from the fitting 213 from the lattice-like water flow structure of the water flow pipe support 239, and negative pressure is generated on the rear end 227 side of the water flow pipe 225 by the force of the water. Thus, a suction force that causes water to flow into the water flow pipe 225 is generated, and the water flow 229 generated in the water flow pipe 225 can be made stronger.

It should be noted that foreign matter such as earth and sand is simultaneously sucked in when the water flows into the water pipe 225 and the water pipe fitting 207, but the strainer 235 is provided at the tip 223 of the water pipe 225. Since the water pipe support 239 having a grid-like water flow structure is provided at the end of the water pipe fitting 113 on the side of the water pipe 225, water and foreign matter are provided by the strainer 235 and the water pipe support 239.

That is, in this embodiment, the energy generating means 231 is configured by including the hydraulic pump 243 and the hydraulic motor 245, so that the hydraulic pump 243 disposed in the water pipe 225 flows in the drain pipe 225. It operates by receiving a driving force from the propeller 241 rotated by the water flow 229.

When the hydraulic pump 243 starts operation, hydraulic pressure is generated, and the hydraulic pressure is supplied to the ground hydraulic motor 245 through the supply path 247A of the hydraulic path 247. In response to the supply of the hydraulic pressure, the hydraulic motor 245 rotates and rotational energy is generated. The hydraulic pressure used for the rotation of the hydraulic motor 245 is sent again to the hydraulic pump 243 through the return path 247B of the hydraulic path 247 and circulated and used.

(3) Electric energy generation process The electric energy generation process is a process of generating electric energy using the generated rotational energy. That is, in this embodiment, rotational energy is generated by the hydraulic motor 245 as described above, and therefore, the generator 233 is driven using the rotation of the output shaft of the hydraulic motor 145 to generate electrical energy. The electricity generated by the generator 233 is transmitted to the original power transmission line side of a power plant (not shown) via a power transmission line (not shown).

The rear end of the water flow pipe 439 is supported by the guide tube 451 through a fixture 433. The fitting 433 is configured so as not to obstruct the water flow in the guide tube 451 (for example, provided intermittently with a gap in the circumferential direction).

The energy generating means 443 is provided on the ground with the above-described hydraulic pump 457 provided with a propeller 455 rotated by the water flow 441 flowing in the water flow pipe 439, and rotated by the hydraulic pressure supplied from the hydraulic pump 457. The hydraulic motor 459 is provided. A plurality of the hydraulic pumps 457 are installed at appropriate intervals so as to be positioned at the center of the water flow pipe 439 by a support rod 461.

As an example, the external shape of the hydraulic pump 457 is a streamline shape, and the propeller 455 is disposed so as to face the distal end portion 437 side of the flowing water pipe 439. The hydraulic pump 457 supplies pressure oil pumped from the hydraulic pump 457 to the ground hydraulic motor 459, and returns the hydraulic oil discharged from the hydraulic motor 459 to the hydraulic pump 457 again. Is connected.

  The hydraulic path 463 includes a supply path 463A for supplying pressure oil to the hydraulic motor 459 and a return path 463B for returning the pressure oil discharged from the hydraulic motor 459 to the hydraulic pump 457. The supply path 463A and the return path 463B fed out from each hydraulic pump 457 are joined to one path on the way, and then connected to the ground hydraulic motor 459.

Next, the power generation method using the flowing water pressure according to the present embodiment, which is executed by using the power generation device 405 using the flowing water pressure, will be described. The power generation method using the flowing water pressure according to the present embodiment is basically configured by including (1) a water flow forming step, (2) a rotational energy generating step, and (3) an electric energy generating step. ing.

(1) Water Flow Formation Step The water flow formation step is a step of forming a water flow 441 in the water flow pipe 439 connected to the flow outlet 404 using the energy of the water that flows out directly from the flow outlet 404. In the present embodiment, the pipe 401 provided with the outlet 404 is connected to a water and sewage system or a river, and is located on the downstream side. In addition, a pipe 403 is provided on the upstream side of the pipe 401 across the power generation device 405, and is connected to a water and sewage system or a river. Therefore, the water flows into the flow pipe 439 from the grid 403 of the strainer 447 provided at the tip 437 of the drain pipe 439 from the pipe 403 side, and flows toward the pipe 401 side. Go. As a result, the water flow 441 is generated.

Further, the water pipe 439 is attached to the inside of a pipe 431 connected to the pipe 401 and the pipe 403 by a water pipe fitting 435. A portion of the water pipe fitting 435 exposed to the upstream side is provided with a water pipe support 453 that supports the water pipe 439 and has a lattice-like water flow structure. Therefore, water also flows from the lattice-like water flow structure of the water flow pipe support 453 through the inside of the water flow pipe attachment 435 to the downstream side. Due to the momentum of water, a negative pressure is generated on the rear end side (left side in FIG. 21) of the water flow pipe 439 to generate a suction force that causes water to flow into the water flow pipe 439, and is generated in the water flow pipe 439. The water stream 441 can be made stronger.

It should be noted that foreign matter such as earth and sand is also sucked at the same time when water flows into the water pipe 439 and the water pipe fitting 435, but the strainer 447 is provided at the tip 437 of the water pipe 439. A water pipe support 453 having a grid-like water flow structure is provided at the tip of the water pipe fitting 435 on the side of the water pipe 439. For this reason, water and foreign matter are separated by the strainer 447 and the flowing water pipe support 453, and only water flows into the flowing water pipe 439 and the flowing water pipe fitting 435.

(2) Rotational Energy Generation Step The rotational energy generation step is a step of generating rotational energy using the water flow 441 formed in the water flow pipe 439. That is, in the present embodiment, the energy generating means 443 is configured by including the hydraulic pump 457 and the hydraulic motor 459, and therefore the hydraulic pump 457 arranged in the water flow pipe 439 passes through the water flow pipe 439. It operates by receiving a driving force from the propeller 455 rotating by the flowing water stream 441.

When the hydraulic pump 457 starts operation, hydraulic pressure is generated, and the pressure oil is supplied to the ground hydraulic motor 459 through the supply path 463A of the hydraulic path 463. In response to the supply of the pressure oil, the hydraulic motor 459 rotates and rotational energy is generated. Further, the pressure oil used for the rotation of the hydraulic motor 459 is sent again to the hydraulic pump 457 through the return path 463B of the hydraulic path 463 and circulated and used.

(3) Electric energy generation process The electric energy generation process is a process of generating electric energy using the generated rotational energy. That is, in this embodiment, rotational energy is generated by the hydraulic motor 459 as described above, and therefore, the generator 445 is driven using the rotation of the output shaft of the hydraulic motor 459 to generate electrical energy. Electricity generated by the generator 445 is transmitted to a power transmission line (not shown) through a power transmission line (not shown).

The propeller 455 is rotated by the water flow 441 generated in the water flow pipe 439 and the hydraulic pump 457 is driven. The hydraulic motor 459 is rotated by the hydraulic pressure supplied from the hydraulic pump 457, and power is generated by the generator 445.
