The invention relates to a power generation module, in particular to a temperature difference actuation power generation module.

In recent years, the awareness of environmental protection and nuclear energy safety in the society has soared. Therefore, the construction of traditional thermal power plants or nuclear power plants often leads to fierce competition and serious social and environmental problems. How to seek a more environmentally friendly, sustainable and safe way of generating electricity is the goal of the world's active efforts today.

In various power generation modes, using environmental temperature difference to generate electricity is an environmentally friendly and safe choice. However, existing systems with ambient temperature difference power generation have the disadvantage of unstable power generation. Specifically, although a large amount of current can be generated when the ambient temperature changes drastically, only a slight current can be generated or cannot be generated when the ambient temperature change is moderated. The current, the instability of the output power, makes the use of environmental temperature difference power generation extremely inconvenient. In addition, the existing environmental thermoelectric power generation system can only generate electricity during one of the increase of the ambient temperature or the decrease of the ambient temperature, and the change of the ambient temperature is usually a cyclical rise and fall cycle, resulting in the inability to convert the environmental temperature difference for nearly half of the time.

The energy storage drive unit is coupled to the magnetic unit for storing energy and outputting to drive the magnetic unit to operate.

The piston unit includes a piston body disposed in the cylinder, and an outer portion extending from the piston body to the outside of the cylinder. The piston body divides the interior of the cylinder into a first chamber and a second chamber that are isolated from each other. The first storage bottle is connected to the first chamber, and the pressure and volume change of the first working fluid during the temperature change causes a pressure difference between the first chamber and the second chamber to drive the cylinder and the piston unit to move relative to each other. The transmission unit connects the cylinder to the energy storage drive unit and transmits the energy of the relative movement of the cylinder and the piston unit to the energy storage drive unit to store the energy of the energy storage drive unit.

The foregoing and other objects, features, and advantages of the invention will be apparent from

Referring to FIG. 1 to FIG. 3, a preferred embodiment of the temperature difference actuation power generation module of the present invention is shown. The temperature difference power generation module comprises a wire unit 1, a magnetic unit having magnetic properties, an energy storage driving unit 3 connected to the magnetic unit 2, a cylinder 4, and a piston unit movable relative to the cylinder 4. 5. A first storage bottle 61 internally storing a first working fluid, a second storage bottle 62 internally storing a second working fluid, and a transmission unit 7 connecting the cylinder 4 and the energy storage drive unit 3.

The wire unit 1 comprises two coils 11 connected to an external system (not shown) and spaced apart from each other. The magnetic unit 2 includes two magnets 21 adjacent to the two coils 11, respectively. Each of the magnets 21 includes two surrounding portions 211 which are spaced apart from each other in parallel, and an intermediate portion 212 that connects the two surrounding portions 211. Each of the coils 11 is located between the two surrounding portions 211 of the corresponding magnets 21. The energy storage driving unit 3 includes two springs 31 respectively connecting the intermediate portions 212 of the two magnets 21, and two ratchet gears 32 connecting the two springs 31 and the transmission unit 7, respectively. The ratchet teeth of the two ratchet gears 32 are formed opposite to each other on a side away from the corresponding spring 31, and are inclined in opposite directions (see Figs. 3 and 6).

Referring to Figures 1 and 4, the piston unit 5 includes a piston body 51 disposed in the cylinder 4, and an outer portion 52 extending from the piston body 51 to the outside of the cylinder 4. The piston main body 51 partitions the inside of the cylinder 4 into a first chamber 41 and a second chamber 42 which are isolated from each other. The first chamber 41 is connected to the first storage bottle 61 to accommodate the first working fluid, and the second chamber 42 is connected to the second storage bottle 62 to accommodate the second working fluid. The first working fluid and the second working fluid may be a gas or a liquid. In this embodiment, the first working fluid and the second working fluid are both a mixture of the refrigerant R-290 and the refrigerant R-600a, and the refrigerant R-290 is adjusted. The mixing ratio with the refrigerant R-600a is such that the first working fluid has a coefficient of thermal expansion greater than the second working fluid. It is easy to understand that the types of the first working fluid and the second working fluid are not limited to the refrigerant state used in the embodiment.

Referring to FIGS. 1 to 3, the transmission unit 7 includes a rack 71 fixed to the cylinder 4, a first gear 72 meshed with the rack 71, and a second gear 73 coaxially fixed to the first gear 72. The output gear 74 meshed with the second gear 73, and two spring pieces 75 respectively projecting from opposite sides of the output gear 74 (see Fig. 6). The output gear 74 is coaxial with the two ratchet gears 32, and the opposite sides face the two ratchet gears 32, respectively, so that the two elastic pieces 75 are respectively connected to the ratchet teeth of the two ratchet gears 32, whereby the output gear 74 rotates in either direction. One of the ratchet gears 32 is unidirectionally rotated by a spring piece 75. In the present embodiment, the second gear 73 is larger than the first gear 72, whereby the gear ratio is designed such that the short-distance displacement of the rack 71 is transmitted through the first gear 72 and the second gear 73 to drive the output gear 74 to rotate substantially.

Referring to FIG. 1 , FIG. 4 , FIG. 5 and FIG. 7 , the temperature difference actuation power generation module of the present invention is suitable for being placed in an environment with a severe environmental temperature change (such as a desert) in use, and fixing the external portion 52 of the piston unit 5 . In an external structure (not shown). As the ambient temperature changes, the temperature of the first working fluid in the first chamber 41 and the second working fluid in the second chamber 42 also change, so that the pressure and volume of the first working fluid and the second working fluid It also changes with temperature. Since the thermal expansion coefficients of the first working fluid and the second working fluid are different, the pressure and volume changes of the first and second working fluids are different when the same temperature change occurs, resulting in a pressure difference between the first chamber 41 and the second chamber 42. One of the first chamber 41 and the second chamber 42 is expanded in volume and the other volume is contracted, and the driving cylinder 4 and the piston unit 5 are caused to move relative to each other.

Cylinder 4 interlocking drive train when moving relative to piston unit 5 The rack 71 of the element 7 generates a linear motion, thereby causing the first gear 72, the second gear 73, and the output gear 74 to rotate. When the output gear 74 rotates, the correspondingly-connected ratchet gear 32 rotates through the elastic piece 75, so that the spring 31 is driven to rotate and store energy when the corresponding ratchet gear 32 rotates, and the mechanical energy of the relative movement of the cylinder 4 and the piston unit 5 is transmitted to the storage. The unit 3 can be driven and stored by the spring 31. The spring 31 storing energy is used for continuously and stably outputting energy to drive the corresponding magnet 21 to operate, so that the surrounding portion 211 of the magnet 21 rotates at a constant speed around the corresponding coil 11 to periodically change the magnetic field around the coil 11 to make the coil 11 Continuously generate a stable induced current output to the external system to achieve the overall power generation efficiency.

It should be emphasized that since the ratchet teeth of the two ratchet gears 32 are inclined opposite to each other (see FIGS. 3 and 6), the output gear 74 rotates clockwise or counterclockwise to drive a ratchet gear 32 to rotate and A corresponding spring 31 stores energy, so that the first chamber 41 is expanded (as shown in FIGS. 5 and 7) or the ambient temperature is lowered to cause the first chamber 41 to contract regardless of the ambient temperature (see FIGS. 1 and 4). The temperature difference actuation power generation module can continuously transfer the energy generated by the temperature difference to a spring 31 for storage for power generation.

Further, it should be noted that the spring 31 used in the present invention is in the form of a going barrel, so that the spring 31 is continuously tightened while the mainspring 31 is tightened by the ratchet gear 32, and the energy driving magnet 21 is continuously rotated. The driving magnet 21 is not stopped because the mainspring 31 is tightening the stored energy. Of course, it is easy to understand that although the transmission unit 7 is connected to the cylinder 4 in the embodiment, and the fixed piston unit 5 is used to cause the cylinder 4 to drive the transmission unit 7 in operation, the transmission unit 7 may be connected to the piston unit 5 instead. And in In use, the fixed cylinder 4 causes the piston unit 5 to drive the transmission unit 7 to operate, and only the transmission unit 7 can be driven by the relative movement of the cylinder 4 and the piston unit 5, which is not limited to the embodiment shown in this embodiment. .

In addition, the temperature difference actuation power generation module of the present invention may also be provided with a working fluid having the same expansion coefficient in the first chamber 41, the first storage bottle 61, the second chamber 42, and the second storage bottle 62. The first storage bottle 61 and the second storage bottle 62 are respectively disposed in two environments with different environmental temperature changes (for example, indoors and outdoors), and the difference between the temperature changes of the first storage bottle 61 and the second storage bottle 62 is made. The volume chamber and the second chamber 42 generate a volume and pressure difference, thereby driving the cylinder 4 and the piston unit 5 to move relative to each other, and are not limited to the first and second working fluids having different expansion coefficients.

In summary, the present invention utilizes the arrangement of the energy storage driving unit 3 to temporarily store the mechanical energy generated by the environmental temperature difference in the spring 31 to stably output the magnetic unit 2 to operate, so that the temperature changes drastically or slowly. The temperature difference-driven power generation module can continuously generate a stable current, which greatly improves the stability and continuity of power generation. In addition, through the opposite design of the ratchet gears of the two ratchet gears 32, when the ambient temperature is raised or lowered, the output gear 74 can drive the spring 31 through the elastic piece 75 and the ratchet gear 32 to store energy for power generation. The conventional temperature difference actuation power generation system has the disadvantage of not being able to convert the temperature difference energy for part of the time. Therefore, the object of the present invention can be achieved.

However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change of the patent application scope and the patent specification content of the present invention is Modifications are still within the scope of the invention.
