Description

  The present invention relates to a power generation apparatus that converts kinetic energy of external force applied to a structure by earthquake, wind power, wave force, etc. into thermal energy, outputs kinetic energy by this thermal energy, and generates electrical energy from kinetic energy.

  Conventionally, as this type of power generation device, the kinetic energy of external force applied to the building structure is converted into thermal energy, and the converted thermal energy is effectively used without being discarded, and the kinetic energy is output from the thermal energy, There has been no conventional example of a configuration for generating electric energy from the output kinetic energy.

  Further, as an attenuation device installed in a building structure in order to attenuate the external force of an earthquake applied to the building structure and safely protect the building structure from being broken, there is JP-A-2004-84845. Is shown in FIG. FIG. 6 is a schematic configuration diagram of a conventional attenuation device.

  In FIG. 6, the conventional damping device is formed with a male screw 50a, and is moved by the male screw 50a to convert the external force applied to the building structure into a linear motion in the screwing direction, and this motion converting means. Rotating motion means 513 formed with a female screw 50b to be engaged with the 50 male screws 50a, and a housing body 512 for supporting the rotating motion means 513 are provided. It is composed of a viscous damping means 53 that moves and attenuates the kinetic energy by the frictional resistance of the viscous fluid 516 accommodated in the housing body 512. A first bearing 511a and a second bearing 511b are interposed between the rotational movement means 513 and the viscosity damping means 53, and the first bearing 511a serves as the rotational movement means 513 and the housing body 512. And the second bearing 511b supports the viscous damping means 53 and the casing body 512 in the rotational direction. As described above, the casing 51 is constituted by the casing main body 512, the rotational movement means 513, the bearing 511a, and the bearing 511b.

  In this way, when relative displacement occurs between the motion conversion means 50 to which the kinetic energy of the external force is transmitted and the housing 51, the rotational motion means 513 is rotated by the male screw 50a and the female screw 50b so that the axis of the motion conversion means 50 is rotated. Rotate around. The viscous damping means 53 rotated in the same direction via the connecting portion 514 by the rotational movement means 513 is caused by the viscous fluid 516 sealed between the viscous damping means 53 and the casing main body 512 with a seal 515. Receives frictional resistance. This frictional resistance generates a force that inhibits the rotational movement of the viscous damping means 53, and the frictional resistance is applied to the sliding surface of the pair of screws including the male screw 50 a and the female screw 50 b via the rotational movement means 513. The frictional force is generated on the sliding surface, and the axial damping force is generated. In this way, the attenuation device can absorb external energy such as earthquakes.

As described above, the conventional damping device has the motion converting means 5 to which the kinetic energy of the external force is transmitted.
When a relative displacement occurs between 0 and the casing 51, the frictional force generated on the sliding surface between the pair of screws 50a and 50b is caused by the rolling sliding surface of the first bearing 511a via the rotational movement means 513. The kinetic energy is attenuated. Furthermore, the viscous fluid 516 generates a viscous frictional resistance that inhibits the rotational movement of the viscous damping means 53, and the kinetic energy is attenuated.
JP 2004-84845 A

Since the conventional damping device is configured as described above, the frictional force generated on the rolling sliding surface is converted into thermal energy on the sliding surface of the bearing 511a, and the metal rotational motion means 513 and The temperature of the bearing 511a is raised and thermally expanded. As a result, the gap between the rotational motion means 513 and the bearing 511a is reduced due to the difference in thermal expansion coefficient between the rotational motion means 513 and the bearing 511a, and in extreme cases, seizure or damage to the damping device itself occurs. End up. Thermal energy is also generated by viscous frictional resistance, and the viscous fluid 516 that has absorbed this thermal energy decreases in viscosity as its temperature rises, leading to a decrease in the damping capability of the damping means itself.

  In this way, it has a function as a thermal energy conversion means for converting kinetic energy into thermal energy at the same time as kinetic energy such as earthquake and wind power is attenuated. Therefore, when used as thermal energy conversion means constituting the power generation device, there is a problem that the energy conversion efficiency cannot be normally functioned or the energy conversion efficiency is poor even if it functions.

  The present invention has been made to solve the above-mentioned problems, and attenuates the kinetic energy of an external force applied to a structure, and effectively and positively uses the thermal energy generated at the time of attenuation, and uses this kinetic energy to An object of the present invention is to provide a power generation device that generates energy reliably and efficiently.

Further, the power generation device according to the present invention comprises a hollow container for containing a viscous fluid therein , if necessary, and the inside of the hollow container is divided into two regions by a partition portion supported by the other end of the motion conversion means. A storage means that divides freely and connects the two regions with a connection flow path, another drive output means that outputs kinetic energy based on the viscous fluid moving in the connection flow path, and the other Power generation means that is driven by the kinetic energy output from the drive output means and generates electrical energy .

Further, in the power generation device according to the present invention, as necessary, the drive output means dissipates heat energy generated between the motion conversion means and the storage means or in a viscous fluid to a liquid heat transfer medium, and The heat transfer medium that has absorbed heat energy is supplied to output kinetic energy .

Further, the power generation device according to the present invention is transmitted by the transmission means that engages with the motion conversion means and rotates based on a straight line or a rotational motion of the motion conversion means , as necessary. Electric power is output by the power generation means by the kinetic energy of the rotational movement .

In the present invention, the external force applied to the structure is converted into kinetic energy of linear or rotational motion by the external thread of the motion conversion means , and the thermal energy conversion means including the internal thread that is screwed into the external thread of the motion conversion means includes a viscous fluid inside. Therefore, the kinetic energy of the external force is attenuated on the sliding surfaces of the male screw and the female screw, and the kinetic energy is converted into thermal energy. The sliding surfaces of the male screw and the female screw are prevented from being burned, and the heat transfer medium vaporized by this heat energy into steam is introduced into the drive output means to output kinetic energy, and this drive output means The electric power can be generated by driving the power generation means by the kinetic energy output from the electric power .

  Further, in the present invention, the external force applied to the structure is converted into linear or rotational kinetic energy by the motion conversion means, the storage means is formed from the hollow container that stores the viscous fluid inside, and the inside of the hollow container is formed. A partition part supported by the other end of the motion conversion means divides the two regions in a movable manner, connects the two regions with a connecting channel, and introduces a viscous fluid moving in the connecting channel with a drive output unit. Since the kinetic energy is output and the electric energy is generated by the power generation means driven by the kinetic energy output from the drive output means, the viscous fluid flows in the connecting flow path from one of the two regions. When moving to the other side, an effect of increasing the speed of the viscous fluid is generated in this connection flow path, and the kinetic energy is output by rotating the drive output means at high speed with this increased viscous fluid. so It becomes Rukoto has the effect of an electric energy of a large capacity can be generated by driving the power generating means by the kinetic energy output from the drive output unit.

  In the present invention, the heat energy generated between the motion converting means and the storage means or in the viscous fluid is radiated to the liquid phase heat transfer medium, and the heat transfer medium that has absorbed the heat energy is supplied to the drive output means. Kinetic energy is output, and electric energy is generated by the power generation means by the kinetic energy output from the drive output means, and the viscous fluid flows from one of the two regions through the connection channel and moves to the other. Due to the speed increasing effect generated in the motor, the drive output means is rotated at a high speed by the increased viscous fluid to output kinetic energy, and the power generation means can generate electrical energy by the kinetic energy output from the drive output means. , It has an effect that large-capacity electric energy can be generated from two systems.

  In the present invention, the external force applied to the structure is converted into kinetic energy of a linear or rotational motion by the motion converting means, and the transmission means engaged with the motion converting means is converted into the linear or rotational motion of the motion converting means. Since the power generation means is driven by the rotational motion transmitted by the transmission means to generate power, the linear or rotational motion of the motion conversion means is converted into the rotational motion of the transmission means. Thus, it is possible to directly drive the power generation means by the kinetic energy transmitted from the transmission means to generate electric energy with little transmission loss.

(First embodiment of the present invention)
Hereinafter, a power generator according to a first embodiment of the present invention will be described with reference to FIG. 5 based on FIG. 1. FIG. 1 is a diagram illustrating an overall configuration of a power generator according to the present embodiment, and FIG. 5 illustrates an arrangement of thermal energy conversion means of the power generator within a building.
In FIG. 1, the power generation apparatus according to the present embodiment is formed integrally with the motion conversion means 10 that converts external force applied to the building structure 160 due to an earthquake or the like into predetermined kinetic energy, and the motion conversion means 10. The thermal fluid converting means 11 for storing the viscous fluid 113 and converting the kinetic energy of the motion converting means 10 into thermal energy by attenuating the external force between the viscous fluid 113 and the motion converting means 10, and the thermal energy conversion. The liquid phase heat transfer medium is supplied to the means 11 by the supply means 14, and the heat energy generated by the heat energy conversion means 11 is absorbed into steam, and the heat transfer medium converted into steam is introduced and kinetic energy is introduced. Drive output means 12 for outputting electric power and electric energy generated by being driven by the kinetic energy output from the drive output means 12 A power generating unit 13, and a condensing means 15 for returning the heat transfer medium in the vapor state which outputs the kinetic energy in the drive output unit 12 to the liquid phase.

  The thermal energy conversion means 11 is installed on the floor surface (or ground) 162 in the building structure 160, and the force transmission means 161 disposed in the building structure 160 is used to externally transmit the earthquake or the like. It is arranged to absorb energy and damp vibrations.

  In addition, the thermal energy conversion means 11 forms a female screw 101 b that is screwed into the male screw 101 a in the housing 111, encloses the viscous fluid 113 in the housing portion 114 in the housing 111, The resistor 112 that slides on the inside is loosely fitted, and the kinetic energy of the motion converting means 10 is attenuated by the frictional resistance of the viscous fluid 113 that flows through the gap between the loosely fitted resistor 112 and the inner wall of the storage 114. The kinetic energy is converted into thermal energy on the sliding surfaces of the male screw 101a and the female screw 101b.

  The motion converting means 10 is formed with a male screw 101a and is screwed by the male screw 101a to convert external force into kinetic energy of linear motion in the screwing direction. Further, in the motion converting means 10, one end 102a of the male screw 101a is rotatably engaged with the receiving portion 165 of the building structure 160, and the other end 102b of the male screw 101a slides in the storage portion 114. The resistor 112 is fixed, and a seal (not shown) is mounted between the storage portion 114 and the resistor 112, and the viscous fluid 113 is sealed in the storage portion 114.

The casing 111 is formed with a cavity 116 adjacent to the sliding surfaces of the male screw 101a and the female screw 101b, and the liquid phase heat transfer medium supplied by the supply means 14 is a supply pipe among the pipes 163. The hollow portion 116 is filled by flowing through the inside 163a. The liquid phase heat transfer medium filled in the cavity 116 contacts the sliding surfaces of the adjacent male screw 101a and female screw 101b without diffusing, and absorbs the heat energy generated on the sliding surface. The heat transfer medium that has been vaporized and turned into vapor flows in the discharge pipe 163 b of the pipe 163 and is introduced into the drive output means 12.
The casing 111 is placed on a moving means 164 movably disposed on the floor (or ground) 162 of the building structure 160, and an external force such as an earthquake acts on one end 117a. In some cases, it can be moved.

  Next, the operation of the power generation apparatus according to this embodiment based on the above configuration will be described based on FIG. 1 and with reference to FIG. When an earthquake or the like occurs and an external force is applied to the building structure 160, and the external force is transmitted to the one end 117a of the casing 111 of the thermal energy conversion means 11 via the force transmission means 161, the casing 111 is While being supported by the moving means 164, it moves in the same direction as an external force such as an earthquake. As the casing 111 moves, the motion conversion means 10 is rotated by the male screw 101a and the female screw 101b, and receives a reaction force in the direction opposite to the external force from the receiving portion 165. Due to this reaction force, the motion conversion means 10 moves relative to the casing 111 while rotating.

  The resistor 112 receives the frictional resistance of the viscous fluid 113 due to the relative rotational movement of the motion converting means 10 with the housing 111. This frictional resistance generates a force that suppresses the motion of the resistor 112, and the frictional resistance becomes a frictional damping force on the sliding surfaces of the male screw 101a of the motion converting means 10 and the female screw 101b of the housing. In this way, the thermal energy conversion means 11 can absorb external energy by attenuating external forces such as earthquakes.

  The thermal energy conversion means 11 absorbs external energy such as an earthquake and converts kinetic energy into thermal energy on the sliding surfaces of the male screw 101a and the female screw 101b when absorbing the external energy. The thermal energy generated by the thermal energy conversion means 11 can be used effectively and positively without being discharged to the outside.

  The heat transfer medium that absorbs the heat energy has a large temperature difference between the boiling point of the heat transfer medium and the temperature at which the sliding surfaces of the male screw 101a and the female screw 101b reach due to heat energy. Since more vapor is obtained, a refrigerant having a low boiling point is used.

  The supply means 14 is maintained in a non-operating state during normal times, starts operating simultaneously with the occurrence of an earthquake, and supplies the refrigerant to the supply pipe 163a in the pipe 163 in a liquid phase state, The refrigerant flowing in the supply pipe 163a is filled in the hollow portion 116, contacts the sliding surfaces of the male screw 101a and the female screw 101b adjacent to the hollow portion 116 without being diffused, and is generated on the sliding surface. Vaporizes by absorbing heat energy.

  The refrigerant that has been vaporized and flows into the discharge pipe 163b of the pipe 163 is introduced into the drive output means 12, and the drive output means 12 is rotated to generate kinetic energy. The power generation means 13 is driven by the kinetic energy output from the drive output means 12 to generate electric energy. Further, the refrigerant in the vapor state from which the kinetic energy is output by the drive output means 12 is changed into a liquid phase by the condensing means 15 and returns to the supply means 14.

  As described above, the power generation apparatus according to the present embodiment positively utilizes the thermal energy generated by the thermal energy conversion means 11 without throwing it outside by applying an external force to the building structure 160 due to an earthquake or the like. Thus, electric energy is generated by the power generation means 13, and an emergency can be avoided such that an earthquake occurs and the electricity in the building structure 160 is usually cut off.

  Further, since the heat transfer medium absorbs heat energy generated on the sliding surfaces of the male screw 101a and the female screw 101b, the sliding surfaces of the male screw 101a and the female screw 101b are prevented from being seized. The damping function of the thermal energy conversion means 11 for attenuating external forces such as earthquakes can maintain the original performance.

(Second embodiment of the present invention)
A power generator according to a second embodiment of the present invention will be described with reference to FIG. 5 based on FIG. FIG. 2 shows the overall configuration of the power generator according to this embodiment. In FIG. 2, the power generation apparatus according to this embodiment is similar to the first embodiment in that the motion conversion means 20 (corresponding to 10), the thermal energy conversion means 21 (corresponding to 11), and the drive output means 22 (corresponding to 12).

Then, the transmission means 26 that rotates based on the linear or rotational movement of the motion converting means 20 and the second driven by the rotational movement of the transmission means 26 through the connecting shaft 266 to generate electric energy. In addition to the power generation means 23 b, a heat exchange means 28 is interposed between the thermal energy conversion means 21 and the drive output means 22.

  The transmission means 26 is configured by meshing a pair of gears 26a and 26b, and is engaged with the motion conversion means 20 so that one gear 26a rotates based on the rotational movement of the motion conversion means 20.

The gear 26b is configured such that the rotational motion of the gear 26b is transmitted to the second power generation means 23b via the connecting shaft 266, and electric energy is generated by the second power generation means 23b. Further, a flywheel 27 and a clutch 27a are pivotally supported on the connecting shaft 266, and the rotational motion shifted by the transmission means 26 is stored in the flywheel 27, and the connecting shaft 266 on the flywheel 27 side is stored. The connecting shaft 266 on the transmission means 26 side is controlled so as to be able to contact and separate by a clutch 27a.

  Further, for the number of teeth Z1 and Z2 of each of the gears 26a and 26b, a pair of gears satisfying a relationship of Z2 = N · Z1 (N is an integer of 1 or more) is used, and N is an integer greater than 1. In this case, the rotation speed of the gear 26b is faster than the rotation speed of the gear 26a, and as a result, the rotation speed of the second power generation means 23b is also increased.

As in the first embodiment, when an earthquake or the like occurs and an external force is applied to the building structure 160, the motion conversion means 20 advances relative to the casing 211 while rotating, and the motion conversion means 20 and the casing are moved. Due to the relative screwing motion of the body 211, the resistor 212 receives the frictional resistance of the viscous fluid 213, and this frictional resistance is a friction damping force on the sliding surfaces of the male screw 201a of the motion converting means 20 and the female screw 201b of the housing 211. It becomes. Thus, the thermal energy conversion means 21 absorbs external energy by attenuating external forces such as earthquakes as in the first embodiment, and when the external energy is absorbed, the sliding of the male screw 201a and the female screw 201b is performed. Converts kinetic energy into thermal energy on the surface.

  The first heat transfer medium (for example, water) absorbs the heat energy generated by the heat energy conversion means 21, and the boiling point is lower than that of the first heat transfer medium that has absorbed the heat energy and the first heat transfer medium. The heat exchanger 29 exchanges heat with a second heat transfer medium (for example, ammonia / water) to perform indirect heating. The second heat transfer medium is supplied from the supply means 24 and absorbs and vaporizes the heat energy of the first heat transfer medium, and the second heat transfer medium that has been vaporized into vapor is the drive output means. 22, the drive output means 22 is rotated to generate kinetic energy, and the first power generation means 23 a can generate electrical energy by the kinetic energy output from the drive output means 22.

  Further, since one gear 26a is rotated based on the rotational movement of the motion converting means 20, the other gear 26b is rotated by the rotational movement of the gear 26a, and the rotational movement of the gear 26b is changed. It is transmitted to the second power generation means 23b via the connecting shaft 266, and electric energy can be generated by the second power generation means 23b.

  As described above, the power generation apparatus according to the present embodiment positively uses the thermal energy generated by the thermal energy conversion means 21 without throwing it outside by applying an external force to the building structure 160 due to an earthquake or the like. As a result, the first power generation means 23a generates electrical energy, and the rotational movement of the motion conversion means 20 is transmitted to the second power generation means 23b via the pair of gears 26a and 26b. Electric power is generated by the power generation means 23b, and each of the electric energy generated by the first power generation means 23a and the second power generation means 23b is added to generate a large capacity. It can be a power generator.

(Third embodiment of the present invention)

First and second drive output means 32a, 32b (corresponding to 12) and first and second power generation means 33a, 33b (corresponding to 13), in addition to this structure, the thermal energy converting means The storage portion 314 (corresponding to 114) of 31 is divided into two regions by a resistor 312 (corresponding to 112) sliding in close contact, and the pipes 363a (corresponding to 163a) and the piping 363b (corresponding to these two regions), respectively. 163b), and the pipes 363a and 363b are connected to the first and second drive output means 32a and 32b, respectively. Unlike the viscous fluid 113 in the first embodiment, the accommodating portion 314 is configured to accommodate a fluid 313 having a very low viscosity.

  Next, the operation of the power generation apparatus according to this embodiment based on the above configuration will be described based on FIG. 3 and with reference to FIG. As in the first embodiment, when an earthquake or the like occurs and an external force is applied to the building structure 160, the motion conversion means 30 advances relative to the casing 311 while rotating, and the motion conversion means 30 and the casing are moved. Due to the relative screwing motion of the body 311, the resistor 312 receives the frictional resistance of the fluid 313, and this frictional resistance is applied to the frictional damping force on the sliding surfaces of the male screw 301 a of the motion converting means 30 and the female screw 301 b of the housing 311. Become. In this way, the thermal energy conversion means 31 absorbs external energy by attenuating external forces such as earthquakes as in the first embodiment, and when the external energy is absorbed, the sliding of the male screw 301a and the female screw 301b. Converts kinetic energy into thermal energy on the surface.

  A fluid 313 that flows due to the movement of the resistor 312 in the illustrated black arrow direction (or the movement in the illustrated white arrow direction) in the housing portion 314 of the thermal energy conversion means 31 passes through the pipe 363b (or 363a). One drive output means 32a (or second drive means 32b) is supplied. With the moving direction of the resistor 312 (black arrow or white arrow), the fluid 313 also flows in the corresponding black arrow direction or white arrow direction. In the case of the black arrow direction, the fluid 313 is supplied to the first drive output means 32a. In the case of the white arrow direction, the valve is controlled so as to be supplied to the second drive output means 32b. The first drive output means 32a or the second drive means 32b converts the kinetic energy of the rotational motion by the inflow of the fluid 313, and rotates the corresponding first or second power generation means 33a, 33b by the kinetic energy. It can be driven to generate electrical energy.

  In addition, although the heat generating apparatus according to the present embodiment has a configuration in which the first and second drive output units 32a and 32b are connected in parallel and the first and second power generation units 33a and 33b generate power complementarily. A single drive output unit and a power generation unit may be used. Alternatively, the supply pipe 363a and the discharge pipe 363b may be cooled and recirculated to the storage unit 314 of the thermal energy conversion means 31 when flowing.

(Fourth embodiment of the present invention)
A power generator according to a fourth embodiment of the present invention will be described with reference to FIG. 5 based on FIG. FIG. 4 shows the overall configuration of the power generator according to this embodiment. In FIG. 4, the power generator according to the present embodiment is configured by combining the first and second embodiments, and includes a motion conversion means 40 (corresponding to 10 and 30), a thermal energy conversion means 41 ( 11 and 31), other drive output means 42, 42a, 42b (corresponding to 12, 32a, 32b), power generation means 43 (corresponding to 13, 33a, 33b), supply means 44 (14) And a condensing means 45 (corresponding to 15), and in addition to this structure, a pipe 463a for supplying a heat transfer medium from the supplying means 44 passes through the receiving portion 165 of the building structure 160. The cooling means 46 is connected to the cavity 416 and is arranged adjacent to the outside of the pipe 463c to return the fluid 413 discharged from the drive output means 42a and 42b to the storage part 414 of the thermal energy conversion means 41. 13 is configured to cool the.

  Next, the operation of the power generator according to this embodiment based on the above configuration will be described based on FIG. 4 and with reference to FIG. As in the first embodiment, when an external force is applied to the building structure 160 due to an earthquake or the like, the motion conversion means 40 advances relative to the casing 411 while rotating, and the motion conversion means 40 and the casing are moved. Due to the relative screwing movement of the body 411, the resistor 412 moves in the storage portion 414 of the supply means 44 in the direction of the black arrow (or the direction of the white arrow in the drawing) to communicate the fluid 413 with the storage portion 414. It discharges to the drive output means 42a (or 42b) through the pipe 463c. In the fluid 413, the frictional resistance generated at the time of discharge becomes a friction damping force on the sliding surfaces of the male screw 401 a of the motion converting means 40 and the female screw 401 b of the housing 411.

  In this way, the thermal energy conversion means 41 absorbs external energy by attenuating external forces such as earthquakes as in the first embodiment, and the external screw 401a and the female screw 401b slide when absorbing this external energy. Converts kinetic energy into thermal energy on the surface. In this thermal energy conversion, first, the heat transfer medium is supplied to the receiving portion 165 to absorb the heat energy generated in the receiving portion 165, and further, in the vicinity of the sliding surfaces of the male screw 401a and the female screw 401b that are larger than the heat generation amount of the receiving portion 165. The heat energy generated on the sliding surface is absorbed by being supplied to the formed cavity 416, and larger heat energy is accumulated in the heat transfer medium.

  The liquid phase supplied from the supply means 44 is the heat energy generated by the heat energy conversion means 41 and the heat energy generated between the one end 402a of the motion conversion means 40 and the receiving portion 165 acting as a universal joint of the building structure 160. The heat transfer medium is absorbed and vaporized, and the vaporized heat transfer medium is introduced into the drive output means 42, and the drive output means 42 is rotated to generate kinetic energy. Electric power can be generated by the power generation means 43 by the kinetic energy output from the output means 42.

  The cooling means 46 absorbs the thermal energy accumulated in the fluid 413 through the pipe 463a. The fluid 413 cooled by the absorption of the heat energy is returned to the storage portion 414.

  As described above, the power generation apparatus according to the present embodiment actively uses the thermal energy generated by the thermal energy conversion means 41 without being discharged to the outside by applying an external force to the building structure 160 due to an earthquake or the like. As a result, the first and second power generation means 43a and 43b generate electric energy by the flow energy of the fluid 413 discharged from the storage portion 414 of the thermal energy conversion means 41, and the motion conversion with the thermal energy conversion means 41 is performed. The power generation means 43 generates electric energy by the heat energy generated between the means 40 and the motion conversion means 40 and the receiving portion 165.

  In addition, in this embodiment, before absorbing the largest heat energy which generate | occur | produces on the sliding surface of the external thread 401a and the internal thread 401b with a heat transfer medium, the building structure 160 which generate | occur | produces less thermal energy than the said sliding surface. Although the heat energy of the receiving portion 165 is absorbed by the heat transfer medium, a pipe 463a is first disposed in the vicinity of the storage portion 414 for storing the fluid 413 having a smaller calorific value than that of the receiving portion 165. Also, a configuration that absorbs heat energy may be adopted. That is, the heat transfer medium supplied from the supply means 44 is sequentially absorbed from a portion with a small amount of heat generation to a portion with a large amount of heat generation, and the heat energy is accumulated in the heat transfer medium. It is possible to output a larger amount of electric energy from the power generation means by driving.

(Other embodiments of the present invention)
A power generation apparatus according to another embodiment of the present invention will be described with reference to FIG. 2 based on FIG. In FIG. 1, the power generation apparatus according to this embodiment includes a motion conversion means 10, a thermal energy conversion means 11, a drive output means 12, a power generation means 13, a supply means 14, and a condensation means 15 as in the first embodiment. It is configured. In addition to the case where an external force such as an earthquake is applied to the building structure 160 as described in the first embodiment, an external force such as a wind force is applied to the building structure 160, and the building structure 160 has a long vibration. The operation of the power generator when it occurs continuously in the meantime will be described.

  When the building structure 160 is vibrated by an external force such as wind force, and this vibration is continuously generated for a long time, the energy of the wind force is converted into heat energy by the thermal energy conversion means 11. The amount of heat generated is enormous. The liquid phase refrigerant is supplied to the thermal energy conversion means 11 by the supply means 14 to absorb this enormous heat energy, and the amount of vapor that is vaporized by vaporization becomes enormous. Therefore, the motion output from the drive output means 12 As the energy increases, the electric energy generated by the power generation means 13 has a large capacity, and this electric energy can be generated during a long period in which the building structure 160 continues to vibrate. In addition, the power generation apparatus according to the present embodiment can function particularly effectively in locations where the average wind speed at which wind power generation is possible occurs throughout the year.

  Moreover, in the electric power generating apparatus which concerns on the said each embodiment, it is set as the structure by which an external force is added to the building structure 160, However, It can apply also about the wave force applied to floating bodies, such as the ocean, or the fluctuation force of the sea surface. For example, in the mounting support portion of the cold seawater intake pipe of the ocean temperature power generation device, the motion conversion means 10 (or 20, 30, 40) is based on an external force such as a wave applied to a floating body such as a buoy constituting the mounting support portion. It is possible to generate electricity by taking it out as kinetic energy. In this way, it is possible to generate electric power with the kinetic energy generated by the shaking while suppressing the influence of the shaking to the cold seawater intake pipe that supports the shaking by absorbing the shaking of the floating body as much as possible.
