Description

  The present invention relates to a system for obtaining power over a long period by circulating a certain amount of fluid.

  Conventionally, thermal power, nuclear power, wind power, geothermal power, solar power, hydraulic power, and the like have been used in technologies for obtaining power using natural energy and generating power based on the power. Among these, when using thermal power or nuclear power, pollution or environmental destruction may be a problem, and there are also cost problems such as fuel and equipment. In addition, wind power, geothermal heat, and solar power are easily affected by the weather, the region, day and night, and have a difficulty in that stable power cannot be obtained.

  In view of such circumstances, techniques for obtaining power and generating power using hydropower as natural energy are widely disclosed. Among the technologies that use hydraulic power, circulating a certain amount of water solves quantitative problems when using hydraulic power, as well as environmental issues without using a drive source such as a motor or internal combustion engine. Has also been proposed (see, for example, Patent Documents 1 and 2).

However, in the prior art, the rotation of the output shaft or the like when obtaining power by circulating water is performed only by the fall of water due to gravity using the height difference. That is, since the output shaft and the like are rotated only by the momentum of the falling water, and the water is not pressurized, it is difficult to efficiently obtain sufficient rotational energy (output energy).
Furthermore, there are few devices that actually obtain energy by circulating such a fixed amount of water in the long run, and the present situation is that only the idea remains.

  Therefore, in the present invention, even if a certain amount of fluid (mainly water) is circulated while applying a high pressure, the difference in height for dropping the fluid is not so large, or the amount of fluid to be circulated is not so large. It is possible to obtain sufficient rotational energy, solve the problems of installation location and quantitative problems due to the height difference, and in addition to a certain amount of fluid, other natural energy such as wind power and driving of motors, etc. Provided is a circulating fluid driving force system that can be operated for a long time only by clean energy without using a source.

  The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

  That is, in the first aspect of the present invention, a circulating fluid driving force system that obtains power by circulating a certain amount of fluid inside a main body container having an upper layer, an intermediate layer, and a lower layer separated by a partition. Provided from the upper layer to the lower layer, provided in a pump for pumping the fluid of the lower layer to the upper layer, and a partition between the upper layer and the intermediate layer, from the upper layer to the A pump-driven water turbine that is driven by a fluid flowing down to the lower layer and drives the pump; a pump operating mechanism that is provided in the upper layer and that transmits the driving force from the pump-driven water wheel to operate the pump; An output water turbine provided in a partition between the intermediate layer and the lower layer, driven by a fluid flowing down from the upper layer to the lower layer, and driving an output shaft for external output; and the upper layer Pressure A pressure holding mechanism for holding the constant, but with a.

  In claim 2, the pump includes a cylinder having a check valve at a lower end, and a piston that is a hollow cylindrical member that reciprocates in the cylinder and has a check valve at the lower end. A plunger-type pump having a fluid passage as a gap between the cylinder and the piston, and the pump moves relative to each other while engaged from both sides with gears fixed to both ends of the pump drive shaft of the pump operating mechanism. A pump unit is composed of a pair of pumps.

  According to a third aspect of the present invention, the piston is configured such that the weight can be adjusted by putting a fluid therein.

  As effects of the present invention, the following effects can be obtained.

  In Claim 1, since power can be obtained by circulating a certain amount of water in the main body container, it can be operated for a long time using only clean energy of water, and the environment is not impaired. Moreover, since the water flowing down among the water circulating in the main body container is in a pressurized state, hydraulic energy comparable to a large-capacity dam or the like can be obtained. That is, there is no need to construct a dam or the like when generating electricity, and there are no regional or installation restrictions. In other words, this circulating fluid driving force system can be optimized in size, scale, and structure for the installation location. In addition, since the operation of each part of the system is performed in the main body container, it is possible to prevent noise and the like from being generated. Furthermore, since there is no need for external input to operate this circulating fluid driving force system, including during initial driving, and there is no need to use a driving source such as a motor, there are few failures and simple maintenance. Long-term operation is possible.

  According to the second aspect, the pump unit can be operated by utilizing the weight of the piston and the buoyancy due to water in addition to the energy of the pump drive unit that is rotated by the water flowing down from the upper layer. Thereby, the rotational energy of the gear fixed to the both ends of the pump drive shaft of the pump operating mechanism can be efficiently used, and the pump can efficiently pump water. That is, it is possible to efficiently use the energy of water circulating in the main body container, and it is possible to pump more water than the amount flowing down from the upper layer from the lower layer to the upper layer. Therefore, since the pressure in the upper layer can be increased, it is possible to obtain a head pressure higher than the level of the water surface in the upper layer and to circulate the pressurized water. In this way, by causing the pressurized water to flow down from the upper layer, it is possible to solve the installation location problem and the quantitative problem due to the height difference.

  According to the third aspect, since the weight of the piston, that is, the specific gravity of the piston with respect to water can be adjusted, it is possible to adjust the buoyancy that the piston obtains from water. As a result, the buoyancy applied to the piston can be set in consideration of the balance with gravity, the resistance of water, etc., and in a series of operations of the piston in a pair of relatively moving pumps, Such torque can be reduced. That is, it is possible to improve the transmission efficiency of energy transmitted from the pump-driven water turbine to the pump unit via the pump operating mechanism.

Next, embodiments of the invention will be described.

  In the circulating fluid driving force system of the present invention, when a fluid such as water collected in a high place naturally flows down to a low place, the head pressure of the fluid always accumulated in the high place is always at any position in the middle of the flow path. Therefore, if the cross-sectional area of the flow path is made constant, the flow rate proportional to the hydraulic head pressure can be maintained, and the kinetic energy from a constant fluid can be always taken out. is there. Hereinafter, the configuration of the circulating fluid driving force system of the present invention will be described with reference to the drawings.

First, the overall configuration of the circulating fluid driving force system of the present invention will be described with reference to FIGS. 1 to 3.
The circulating fluid driving force system of the present invention circulates a certain amount of fluid in a substantially sealed hollow cylindrical main body container 1 that is placed and fixed on a disk-shaped base table 2. It can be obtained. In the following description, water that is generally widely used is used as an example of a fluid that circulates inside the main body container 1.

  The main body container 1 is partitioned into three spaces, an upper layer 3, an intermediate layer 4, and a lower layer 5, by a partitioning portion. That is, the upper partition 3 separates the upper layer 3 and the intermediate layer 4, and the lower partition 7 separates the intermediate layer 4 and the lower layer 5. The layers are substantially sealed except for a water passage.

  A pump unit 50 including a pair of plunger-type pumps 51 and 51 that move relative to each other for pumping water from the lower layer 5 to the upper layer 3 is provided in the main body container 1 from the lower layer 5 to the upper layer. It is erected over three. That is, the pumps 51 and 51 of the pump unit 50 maintain the sealed state of the respective layers by the upper and lower partition parts 6 and 7 and are provided through the lower partition part 7 and the upper partition part 6 from the lower layer 5 to the upper layer 3. It has been.

A pump-driven water turbine 8 for driving the pump unit 50 is provided at a substantially central portion of the upper partition 6 that is a partition between the upper layer 3 and the intermediate layer 4. A pump operating mechanism 10 for operating the pump unit 50 by transmitting the driving force of the pump driven turbine 8 is provided above the pump driven turbine 8, that is, in the upper layer 3.
Further, an output turbine 9 having an output shaft 15 of the circulation type fluid driving force system is provided at a substantially central portion of the lower partition portion 7 which is a partition portion between the intermediate layer 4 and the lower layer 5.

  The upper partition 6 and the lower partition 7 are respectively supported above the upper part of each of the pump-driven water turbine 8 and the output water turbine 9 and for ensuring the momentum of water flowing into the respective pumps. A partition plate 6a and a partition plate 7a that form the space are provided (see FIG. 1). In these partition plates 6a and 7a, a plurality of water passage holes are formed at arbitrary positions so that the water can flow downward.

In the configuration as described above, the upper layer 3 and the lower layer 5 in the main body container 1 always store water therein as an upper tank portion and a lower tank portion, respectively, and the water flows from the upper layer 3 to the lower layer 5. As a result, the pump-driven water turbine 8 and the output water turbine 9 are driven.
Then, when the output water wheel 9 is rotationally driven, the output shaft 15 for outputting power from the circulating fluid driving force system to the outside is rotationally driven. Further, the pump unit 50 is operated via the pump operating mechanism 10 when the pump-driven water turbine 8 is rotationally driven.
By the operation of the pump unit 50, the water accumulated in the lower layer 5 is pumped up to the upper layer 3, and the upper layer 3 is always replenished with water. That is, the pump-driven turbine 8 and the output turbine 9 are configured to continue to rotate unless the flow of water flowing from the upper layer 3 to the lower layer 5 is stopped.
Note that a plurality of output water turbines 9 can be arranged in parallel in the lower partition 7 or a plurality of output turbines 9 can be arranged in series in the intermediate layer 4. In this manner, by providing a plurality of output water turbines 9, a plurality of output extraction portions (output shafts 15) can be provided.

In this way, the water is circulated through the inside of the main body container 1 by the flow of water from the upper layer 3 to the lower layer 5 and the pumping of water by the pump unit 50 from the lower layer 5 to the upper layer 3. The shaft 15 is rotationally driven, and the driving force (rotational energy) is obtained by the rotation of the output shaft 15.
And as an example of embodiment of the circulation type fluid drive force system which concerns on this invention, it becomes a thing of an external appearance as shown in FIG.
Hereinafter, the details of the configuration of each part in the circulating fluid driving force system will be described.

First, the output turbine 9 will be described with reference to FIGS.
The output water turbine 9 has a rotor 13 that rotates in a substantially cylindrical case 12 by the momentum of flowing water. The case 12 is divided into two spaces, an upper space 12a and a lower space 12b, and the rotor 13 is rotatable in the upper space 12a by a vertical rotation shaft 13a supported up and down via a bearing or the like. It is supported. A valve plate 14 for adjusting the amount of water flowing from the output water turbine 9 to the lower layer 5 is provided in the lower space 12 b of the case 12.

The rotor 13 has a plurality of (three in the present embodiment) blades 16. These blades 16 are provided so as to be able to enter and exit in the radial direction in the plan view of the rotor 13. That is, the rotor 13 is formed with a recess 13b in which the blade 16 is accommodated, and the blade 16 protrudes when water flows into the gap between the recess 13b and the blade 16.
Therefore, a groove portion 16 a is formed on the side surface of the blade 16 to promote the inflow of water into the gap between the recess 13 b and the blade 16.
In addition, the spring member which pushes out the blade | wing 16 in the direction which protrudes in the recessed part 13b is provided, and the blade | wing 16 can be protruded also with a spring member in addition to the water which flows in into the recessed part 13b.

A water inlet 12c through which water flows into the case 12 is formed on one side of the side surface of the case 12, and the water in the case 12 is drained out of the case 12 on the bottom surface of the case 12 as well. For this purpose, a drain port 12d is formed.
In addition, a convex portion 12 e is formed on the inner side surface of the side surface of the upper space 12 a of the case 12 for urging the storage of the blades 16 in the rotor 13 as the rotor 13 rotates. The convex portion 12 e is provided immediately before the water inlet 12 c with respect to the rotation direction of the rotor 13, and is formed so that the tip portion is substantially in contact with the rotor 13. That is, as shown in FIG. 5, the upper space 12 a of the case 12 is partitioned by the convex portion 12 e and the rotor 13.

In such a configuration, water always flows from the water inlet 12c, the rotor 13 rotates, and the blades 16 are accommodated in the concave portion 13b along the curved surface of the convex portion 12e. Thereafter, the blade 16 passes through the substantially contact portion between the convex portion 12 e and the rotor 13, and at the same time, the water flowing in from the water inlet 12 c flows into the gap between the blade 16 and the concave portion 13 b of the rotor 13. As a result, the blades 16 are projected, and the blades 16 are pushed by the momentum of water from the water inlet 12c, so that the rotor 13 obtains a rotational force.
And the water which flowed in from the water inlet 12c and gave the rotational force to the rotor 13 is discharged | emitted as it is from the drain outlet 12d to the lower lower space 12b. In other words, the inflowing water actually gives a rotational force to the rotor 13 due to the flow of water between the water inlet 12c and the water outlet 12d. Rotational force is gained through.
That is, the convex portion 12e formed on the inner surface of the case 12 partitions the upper space 12a of the case 12 by being substantially in contact with the rotor 13, so that the momentum of water flowing from the water inlet 12c is not dispersed. Yes. The blades 16 are provided so as to be able to enter and exit from the rotor 13 in order to correspond to the partition by the convex portions 12e.

The rotational energy obtained in the output water turbine 9 having such a structure is obtained by using a bevel gear 17a fixed to the end of the drive shaft 17 provided coaxially with the rotation shaft 13a of the rotor 13 and upward, and the umbrella Rotational energy is given to the output shaft 15 of the circulating fluid driving force system via the bevel gear 15a meshing with the gear 17a.
The meshing portion of the bevel gears 17a and 15a is covered with a gear case 18 filled with lubricating oil, so that contact with water can be cut off and smooth power transmission can be achieved.

  On the other hand, the water that flows down from the upper space 12a of the case 12 through the drain port 12d flows into the lower space 12b. A plurality of (four in this embodiment) discharge holes 12f for allowing water to flow down to the lower layer 5 are formed on the bottom surface of the lower space 12b. The discharge holes 12f are formed on the discharge holes 12f. The valve plate 14 that can be closed is rotatably provided. The valve plate 14 is a cross-shaped plate member in plan view, and has a rotation shaft 14a at the center thereof, and the discharge hole 12f can be opened and closed by rotating around the rotation shaft 14a. it can. That is, by adjusting the rotation of the valve plate 14, the amount of water flowing down from the discharge hole 12f can be adjusted.

  And the rotating shaft 14a of the valve plate 14 is extended toward the downward direction, and the pinion gear 20 is fixed to this lower end part. A rack gear 21 meshes with the pinion gear 20, and the rack gear 21 extends outside the main body container 1 and can be operated from the outside of the main body container 1 (see FIG. 3). The pinion gear 20 is moved in the direction of rotation by rotating the. That is, the rotation of the valve plate 14 can be adjusted by operating the output adjustment handle 19 that can be operated from the outside of the main body container 1.

  From such a structure, the rotation of the valve plate 14 can be adjusted by operating the output adjustment handle 19, and the amount of water flowing down from the discharge hole 12f can be adjusted. The rotation of the rotor 13 of the output water turbine 9 can be adjusted by adjusting the amount of water flowing down from the discharge hole 12f. Further, the rotation of the output shaft 15 can be stopped by closing the discharge hole 12f by the valve plate 14. That is, the output adjustment handle 19 can adjust the driving force obtained from the output shaft 15 and stop the output.

Next, the pump drive turbine 8 will be described with reference to FIG.
The pump-driven water turbine 8 has a rotor 23 having substantially the same structure as the above-described output water turbine 9 in the case 22, and has a structure for obtaining rotational energy by the flow of water flowing into the case 22. The rotational energy obtained by the pump-driven turbine 8 is generated by the bevel gear 25a fixed to the end of the drive shaft 25 provided coaxially with the rotation shaft of the rotor 23 and upward, and the bevel gear 25a. The gears are meshed and transmitted to the transmission shaft 26 via a bevel gear 26 a fixed to one end of the transmission shaft 26. The rotational energy of the transmission shaft 26 is transmitted to the pump unit 50 via a bevel gear 26b fixed to the other end of the transmission shaft 26 and a transmission shaft 27 having a bevel gear 27a meshing with the bevel gear 26b. It is structured to be transmitted to the pump operating mechanism 10 to be operated.
The meshing portions of the bevel gears 25a and 26a and the bevel gears 26b and 27a are also covered with a gear case 24 filled with lubricating oil, so that contact with water is cut off and smooth power transmission is enabled. be able to.

Next, the pump operating mechanism 10 will be described with reference to FIGS.
The pump operating mechanism 10 is a mechanism for regularly operating the pump unit 50 by transmitting rotational energy obtained by the pump-driven water turbine 8 to the pump unit 50.
The pump actuating mechanism 10 is engaged with a pinion gear 27b fixed to the upper end of the transmission shaft 27 and a gear wheel 28 to which power from the pump-driven water turbine 8 is transmitted symmetrically with an upper mechanism having substantially the same structure up and down. The lower mechanism is shifted by 90 degrees with respect to the center of the main body container 1 in plan view. That is, the upper cam plate 29 and the lower cam plate 30 are respectively fixed above and below the gear wheel 28, and the upper mechanism is driven by the upper cam plate 29 and the lower mechanism is driven by the lower cam plate 30.
In the following description, only the upper mechanism will be described for portions common to the upper mechanism and the lower mechanism, and the description of the lower mechanism will be omitted by attaching the same reference numerals.

  The gear wheel 28 forms a gear unit 31 together with an upper cam plate 29 and a lower cam plate 30, and the gear unit 31 includes a substantially cylindrical drum 32 and a disk-shaped upper base plate fixed above and below the drum 32. 33 and the lower base plate 34, and is housed in a cylindrical case configured integrally with the main body container 1. The gear unit 31 is rotatably supported in this case. That is, a plurality of support rollers 35 are erected on the lower base plate 34, and the gear unit 31 is rotatable by fitting the outer peripheral portion of the lower cam plate 30 of the gear unit 31 to these support rollers 35. Supported in state.

A rack gear 37 is provided at the center of the upper base plate 33 so as to be slidable through long plate-like guide plates 36 and 36 with the tooth surfaces facing the upper and outer sides of the upper base plate 33. The guide plates 36 and 36 are fixed to a substantially central portion of the upper base plate 33 with a slight gap therebetween, and the rack gear 37 slides while being sandwiched between the two guide plates 36 and 36.
For this reason, groove portions for fitting the guide plates 36 and 36 are formed on both side surfaces of the rack gear 37, and are substantially letter-shaped in a sectional view in the sliding direction. That is, the rack gear 37 is slidably supported on the upper base plate 33 by the guide plates 36 and 36 being fitted to both side surfaces thereof, and the diameter direction of the upper base plate 33 is supported by the guide plates 36 and 36. The sliding direction is restricted.

  The rack gear 37 has rollers 38 on the lower side at the front and rear ends in the sliding direction. The rollers 38 are provided so as to come into contact with the inner peripheral surface of the upper cam plate 29, and the rack gear 37 is slid by the rotation of the upper cam plate 29 as the gear unit 31 rotates. That is, the inner peripheral surface of the upper cam plate 29 (and the lower cam plate 30) is formed in a substantially heart shape in plan view, and when the upper cam plate 29 rotates, the rack gear 37 rotates the rollers 38 and 38. It is configured to slide in a direction regulated by the guide plates 36 and 36 via the. In other words, the upper cam plate 29 converts the rotational motion of the gear unit 31 into the reciprocating linear motion of the rack gear 37.

  On the upper base plate 33, a pump drive shaft 39 is rotatably supported at its left and right end portions and an intermediate portion by bearing bases 40, 40, 40, and is provided in a state orthogonal to the rack gear 37 in plan view. Yes. The pump drive shaft 39 has a pinion gear 39 a that meshes with the tooth surface of the rack gear 37 at the center thereof, and is configured to rotate as the rack gear 37 reciprocates linearly. Gear wheels 42 and 42 that transmit power to the pump unit 50 are fixed to both ends of the pump drive shaft 39.

  The pump operating mechanism 10 having such a configuration drives the pair of pump units 50 and 50 facing each other by the upper structure and drives the other pair of pump units 50 and 50 by the lower structure. In the main body container 1, the pump units 50 erected from the lower layer 5 to the upper layer 3 can operate without interfering with each other.

  With the pump operating mechanism 10 configured as described above, the rotational energy from the pump-driven water turbine 8 is transmitted to the gear wheel 28 via the pinion gear 27b of the transmission shaft 27, and the upper wheel plate 29 and the lower cam wheel 29 are rotated by the rotation of the gear wheel 28. The cam plate 30 also rotates, and the upper and lower rack gears 37 reciprocate linearly as the upper and lower cam plates rotate. The reciprocating linear movement of the rack gear 37 causes the pinion gear 39a to rotate the pump drive shaft 39 while alternately changing the rotation direction within a certain rotation range. Accordingly, the gear wheels 42 and 42 at both ends of the pump drive shaft 39 also rotate while changing the rotation direction alternately within a certain rotation range. This rotational movement of the gear wheels 42, 42 activates each pump 51 of the pump unit 50.

Next, the pump unit 50 and the pump 51 will be described with reference to FIG.
The pump 51 is a plunger type pump, and constitutes a pump unit 50 that makes a relative motion in pairs.
The pump 51 includes a gate-like base portion 52 in a side sectional view, a cylindrical cylinder 53 erected on the base portion 52, and a piston 54 that slides inside the cylinder 53.

The cylinder 53 has a check valve 55 that opens and closes a water suction port 53 a formed at the lower end thereof by a valve body 56.
The piston 54 is fixed to a piston main body 57 that is a hollow cylindrical member, a rack gear 58 that is fixed to the upper surface of the piston main body 57 and meshes with the gear wheel 42 of the pump operating mechanism 10, and a lower end portion of the piston main body 57. And a piston head 59.

  The outer diameter of the piston main body 57 is set so as to have a slight gap between the inner diameter of the cylinder 53. And this clearance gap becomes a passage of water so that it may mention later. Further, the piston body 57 has a check valve 60 that opens and closes the water inlet 57a formed at the lower end portion by the valve body 61 while separating the internal space by providing a partition 57b on the lower end side of the hollow interior. Yes. A passage hole 57c through which water passes is formed on the side surface below the partition 57b of the piston body 57.

The rack gear 58 extends upward from the upper end portion of the piston main body 57 in the piston 54, and its tooth surface is engaged with the gear wheel 42 of the pump operating mechanism 10, thereby rotating the gear wheel 42 in the vertical direction of the piston 54. It is converted into motion. Therefore, the piston 54 has a length sufficient to correspond to the piston stroke in the cylinder 53.
The piston head 59 is an annular member having an outer diameter substantially the same as the inner diameter of the cylinder 53 and having a water absorption hole 59a at the center.

The action of pumping water by the pump 51 having the above configuration will be described with reference to FIG.
First, when the piston 54 rises in the cylinder 53, the check valve 55 at the lower end of the cylinder 53 is opened, and water collected in the lower layer 5 is formed at the lower portion of the base 52. And flows into the cylinder 53 through the check valve 55. At this time, the check valve 60 at the lower end of the piston 54 is closed by water pressure, and water does not flow down from the piston 54 side. Thus, when the piston 54 rises, the water from the lower layer 5 enters the space below the piston head 59 in the cylinder 53 (see FIG. 10A).

  When the piston 54 descends from the state where water is accumulated below the cylinder 53, the water in the cylinder 53 is compressed by the piston head 59 so that the check valve 55 of the cylinder 53 is closed. At the same time, the check valve 60 at the lower end of the piston 54 is opened. That is, the water in the cylinder 53 flows into the piston 54 from the water absorption hole 59a of the piston head 59 via the check valve 60, and is discharged out of the piston 54 from the passage hole 57c of the piston body 57. Ascends through the gap with 53 and is discharged from the opening 53b at the upper end of the cylinder 53 (see FIG. 10B). Since the opening 53 b of the cylinder 53 opens in the upper layer 3, the water pumped up by the pump 51 accumulates in the upper layer 3. That is, in this pump 51, the gap between the cylinder 53 and the piston main body 57 of the piston 54 is used as a water passage, and water in the lower layer 5 is pumped up to the upper layer 3.

  A pump 51 that pumps water from the lower layer 5 to the upper layer 3 with such a structure is disposed with the rack gear 58 engaged with the gear wheel 42 of the pump operating mechanism 10 from the left and right sides, and a pair of pump units that move relative to each other. 50. In the pump unit 50, when the piston 54 of one pump 51 is raised as the gear wheel 42 rotates, the piston 54 of the other pump 51 is lowered. That is, the pair of pistons 54 is lifted and lowered by the same length in opposite directions, and the pair of pumps 51 alternately pumps water.

In such a structure, the piston main body 57 is made hollow so that buoyancy from water can be obtained. That is, the piston 54 can receive buoyancy by water in the cylinder 53 within a distance range that approximates the piston stroke. In order to efficiently use this buoyancy, the piston 51 is engaged by engaging the rack gear 58 from both the left and right sides with the gear wheel 42 fixed to both ends of the pump drive shaft 39. Is placed in a suspended state.
By carrying out like this, both pistons 54 will be in the state which balanced by making the weight of each piston 54 in a pair of pump 51 into the same. That is, as in a balance having the pump drive shaft 39 as a fulcrum, both pistons 54 are always subjected to a force for maintaining a balance.

  As described above, the pump unit 50 operates by utilizing the self-weight of the piston 54 and the buoyancy due to water in addition to the rotational energy of the pump-driven turbine 8 due to the water flowing down from the upper layer 3. As a result, the rotational energy of the gear wheel 42 can be used efficiently, water can be pumped by the pump 51 more efficiently, and more water than the amount flowing down from the upper layer 3 can be pumped from the lower layer 5 to the upper layer. Can be pumped up to 3.

  Further, the piston main body 57 is configured so that a fluid such as water or other weight can be put into the hollow interior thereof. For example, a lid body 57d whose upper surface can be opened and closed allows a weight such as water to be put inside the piston main body 57, and the weight of the piston 54 can be adjusted. At this time, in order to reduce the power related to the operation of the pump 51 by obtaining buoyancy due to water, the specific gravity of the piston 54 with respect to water is set to be smaller than 1 (set to about 0.6 in this embodiment).

With such a configuration, the weight of the piston 54, that is, the specific gravity of the piston 54 with respect to water can be adjusted, so that the buoyancy that the piston 54 obtains from water can be adjusted. That is, the buoyancy applied to the piston 54 takes into account the balance with gravity, the resistance of water, and the like, and the torque applied to the pump drive shaft 39 of the pump operating mechanism 10 is small in each process of the piston 54 ascending and descending in the pump 51. Is set to be
Thereby, the transmission efficiency of the energy transmitted to the pump unit 50 from the pump drive water turbine 8 via the pump operation mechanism 10 can be improved.

A series of power transmission from the pump-driven water turbine 8 to the pump unit 50 in the above configuration will be described.
First, the pump-driven turbine 8 is rotated by the water flowing down from the upper layer 3. The rotational energy of the pump-driven water turbine 8 is transmitted to the transmission shaft 27 via a bevel gear or the like. The rotational energy of the transmission shaft 27 is transmitted to the gear wheel 28 of the gear unit 31 through the pinion gear 27b. As the gear wheel 28 rotates, the upper cam plate 29 and the lower cam plate 30 also rotate.
As the upper and lower cam plates rotate, the rack gears 37 of the upper structure and the lower structure of the pump operating mechanism 10 reciprocate linearly. The upper and lower pump drive shafts 39 rotate while changing the rotation direction alternately within a certain range by the rack gears 37 that reciprocate linearly in a direction orthogonal to each other in plan view above and below the gear unit 31.
The pistons 54 of the pumps 51 are moved up and down through the rack gear 58 by the rotation of the gear wheels 42 and 42 fixed to both ends of the pump drive shaft 39. That is, each of the upper and lower rack gears 37 reciprocates once by rotating the gear wheel 28 once, and the pair of pumps 51 of the pump unit 50 discharges water one by one by reciprocating the rack gear 37 once. It has become.

Further, since the upper and lower pump drive shafts 39 are provided in a state orthogonal to the respective rack gears 37, they are in an orthogonal state in plan view. That is, as shown in FIG. 2, the pump units 50 including a pair of pumps 51 are installed for the gear wheels 42 at both ends of each pump drive shaft 39, so that a total of four sets of pump units 50 ( A total of eight pumps 51) are provided so as not to interfere with each other.
In this way, a certain amount of water is circulated in the main body container 1 by operating the plurality of pumps 51 by the pump-driven water turbine 8. The output water wheel 9 is rotated by the force of the circulating water, and the output from the output shaft 15 is obtained. The number of pump units 50 provided in the main body container 1 of the circulation type fluid driving force system is not limited to this embodiment, and a plurality of output shafts may be provided from one output turbine 9. A plurality of output water turbines 9 can be provided.

  At the time of initial driving of the circulating fluid driving force system configured as described above, first, an appropriate amount of water is stored in each of the upper layer 3 and the lower layer 5. In this state, the upper layer 3 and the lower layer 5 are not filled with water, and predetermined spaces are secured respectively. That is, in the upper layer 3, the amount of water in the upper layer 3 is increased by the pumped water to obtain a high pressure. Therefore, in the lower layer 5, the momentum of water flowing down from the output water turbine 9 is secured, and the output water turbine 9 In order to ensure the rotation speed of the water, the water is adjusted so that it is not filled with water in each. The same is true while water is circulating during operation of the circulating fluid drive system.

From this initial driving state, the pump-driven water turbine 8 starts to be driven by the water flowing down from the upper layer 3. Then, each pump unit 50 is operated via the pump operating mechanism 10 by the power of the pump-driven water turbine 8. By the operation of the pump unit 50, water in the lower layer 5 is pumped up and water is always supplied to the upper layer 3.
Since the amount of water pumped up by the plurality of pump units 50 is larger than the amount of water flowing down from the upper layer 3, the pressure in the upper layer 3 rises. Thereby, the water head pressure more than the height of the water surface in the upper layer 3 can be obtained, and it becomes possible to circulate the pressurized water.

In order to prevent the pressure of the upper layer 3 from rising more than necessary, a bypass 66 having a pressure regulating valve 65 communicates the upper layer 3 with the intermediate layer 4 and the lower layer 5 as a pressure holding mechanism. (See FIG. 1). Thereby, when the pressure in the upper layer 3 becomes equal to or higher than the pressure set by the pressure regulating valve 65, the water in the upper layer 3 is discharged to the intermediate layer 4 and the lower layer 5 through the bypass 66. The
That is, the sum of the amount of water flowing from the upper layer 3 to the lower layer 5 and the amount of water flowing into the lower layer 5 through the bypass 66 is substantially the same as the amount of water pumped by the pump unit 50. It is possible to circulate the pressurized water in the container 1 for a long time.

Further, in order to secure the momentum of the water flowing down from the output water turbine 9, the lower layer 5 desirably has an internal pressure that is substantially the same as the atmospheric pressure (more preferably a negative pressure). Therefore, the lower layer 5 is provided with an air vent 67 for communicating the lower layer 5 with the outside air (see FIG. 1). By providing the air vent 67, the pressure inside the lower layer 5 is always substantially the same as the atmospheric pressure, the momentum of the water flowing down from the output water turbine 9 can be secured, and the rotational energy from the output shaft 15 is always stable. Can be obtained. In addition, it is also possible to promote the circulation of the water in the main body container 1 by making the inside of the lower layer 5 into a negative pressure by a vacuum pump or the like from the outside of the main body container 1 of the air vent 67.
Moreover, the drain 68 for draining the water in the main body container 1 or replacing the water at the time of maintenance or the like is provided at the lower end of the main body container 1 (see FIG. 3).

By using the circulating fluid driving force system of the present invention described above, the following effects can be obtained.
First, since power can be obtained by circulating a certain amount of water in a certain body container 1, it can be operated for a long time using only clean energy such as water, and the environment is not impaired. Moreover, since the water flowing down among the water circulating in the main body container 1 is in a pressurized state, it is possible to obtain hydraulic energy comparable to a large-capacity dam or the like. That is, there is no need to construct a dam or the like when generating electricity, and there are no regional or installation restrictions. In other words, this circulating fluid driving force system can be optimized in size, scale, and structure for the installation location.
Moreover, since the operation | movement of each part of this system is performed in the main body container 1, it can prevent generating a noise.
Furthermore, since there is no need for external input to operate this circulating fluid driving force system, including during initial driving, and there is no need to use a driving source such as a motor, there are few failures and simple maintenance. Long-term operation is possible.

As an application example of the present invention, it can be widely and generally used for power generation. When this system is used for power generation, an external input is not required and independent operation is possible. Therefore, it is possible to prevent power outages all at once by using a plurality of this system. This power generation can also be used as driving energy for electric vehicles. In this case, the electric vehicle continues to generate electricity while traveling and does not require charging.
It is also conceivable that the fluid to be circulated is compressed / pressurized air to be used as an air engine system. In this case, the high-pressure air engine system can be used as a power source for an aircraft, a ship, and the like, and serves as a power source for moving an aircraft turbine and a propeller of a propeller aircraft.

Furthermore, it is possible to apply the circulation type of this circulation type fluid driving force system to precision systems such as nanotechnology. In this case, it can be used for, for example, an artificial heart-lung machine or an artificial dialysis system in the medical field.
Moreover, the possibility of utilization as an air conditioning system is conceivable by using this circulation form for circulation of air itself. In this case, it can be used from a small space facility such as a vinyl house to a large space facility such as a dome type facility.
