[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] Implementation Method 1

[0057] The present invention provides a gas tank potential energy power generation system, which is mainly used to solve the problem of recovering the pressure potential energy of the gas in the gas tank, so as to achieve the effect of energy conservation and emission reduction.

[0058] Please refer to Figures 1 to 10 In an embodiment of the present invention, a gas tank potential energy power generation system is provided, comprising: a gas tank 1 having a piston 11; a winding device 2 rotatably arranged on the piston 11; a power generation device 3, which is detachably connected to the winding device 2; and a counterweight 12, which is connected to the winding device 2 through a connecting member 9. The counterweight 12 has at least a first potential energy state and a second potential energy state. Switching the counterweight 12 from the first potential energy state to the second potential energy state drives the winding device 2 to rotate, thereby driving the power generation device 3 to generate electrical energy.

[0059] Overall, refer to Figures 1 to 6 The present invention arranges the winding device 2 and the power generation device 3 on the piston 11 of the gas tank 1, and the winding device 2 and the power generation device 3 can move up and down with the piston 11. The counterweight 12 in the present invention is connected to the winding device 2 through the connecting member 9. The winding device 2 can pull the counterweight 12 during the up and down movement of the piston 11, and pull the counterweight 12 from the second potential energy state to the first potential energy state, thereby converting the gas pressure potential energy into the gravitational potential energy of the counterweight 12, realizing the recovery process of the gas pressure potential energy. When power generation is required, the winding device 2 and the power generation device 3 are connected, and the counterweight 12 is released to drive the power generation device 3 to generate electricity, thereby realizing the reuse process of the gas pressure potential energy. The present invention can recycle and reuse the gas pressure potential energy through the winding device 2, the power generation device 3 and the counterweight 12, thereby reducing energy waste, improving the utilization rate of the internal energy of the gas, and playing a role in energy conservation and emission reduction.

[0060] Wherein, counterweight 12 can be a counterweight block, and connector 9 can be a cable. Certainly, designers also can be set to other structures with counterweight 12 and connector 9 as required, and do not limit here.

[0061] For details, please refer to Figure 7 and Figure 8 A first coupling structure 4 is provided between the power generation device 3 and the winding device 2 , and the power generation device 3 and the winding device 2 are detachably connected through the first coupling structure 4 .

[0062] The first coupling structure 4 detachably connects the generator 3 and the winding device 2. When power generation is not required, the first coupling structure 4 is unlocked, disconnecting the generator 3 and the winding device 2. This locks the winding device 2, and the piston 11 pulls up the counterweight 12. When power generation is required, the first coupling structure 4 is locked, connecting the generator 3 and the winding device 2. The counterweight 12 then synchronously drives the winding device 2 and the generator 3, thereby driving the generator 3 to generate electricity.

[0063] Specifically, the winding device 2 includes a first rotating shaft 21 and a winding wheel 22 arranged on the first rotating shaft 21. The winding wheel 22 is provided with a winding groove 221 for winding the connecting member 9.

[0064] During use of the winding device 2, in order to prevent the winding wheel 22 from rotating when pulling the counterweight 12 and affecting the pulling effect, a locking structure such as a block or a bolt can be provided on the winding device 2 to lock the first rotating shaft 21 or the winding wheel 22. Of course, the designer can also adjust the locking structure according to the needs of use, and this is not limited here.

[0065] In the embodiment of the present invention, the power generation device 3 includes a generator 31 and a second rotating shaft 32 provided on the generator 31 . The second rotating shaft 32 is detachably connected to one end of the first rotating shaft 21 via a first coupling structure 4 .

[0066] When the counterweight is used to generate electricity, the first rotating shaft 21 is connected to the second rotating shaft 32 through the first coupling structure 4, and the counterweight 12 drives the winding wheel 22 and the generator 31 to rotate synchronously through the connecting member 9 for generating electricity.

[0067] Specifically, the first coupling structure 4 includes a first sleeve 41 arranged at one end of the first rotating shaft 21, a second sleeve 42 arranged on the second rotating shaft 32, and a first locking member 43 arranged between the first sleeve 41 and the second sleeve 42. The first locking member 43 is detachably connected to the first sleeve 41 and the second sleeve 42.

[0068] By disposing a first locking member 43 between the first sleeve 41 and the second sleeve 42, the first coupling structure 4 can be unlocked by removing the first locking member 43. At this time, a gap remains between the first sleeve 41 and the second sleeve 42, which does not affect the normal operation of the winding device 2 and the power generation device 3.

[0069] Furthermore, in order to prevent relative rotation between the rotating shaft and the sleeve, a keyway structure can be set between the first sleeve 41 and the first rotating shaft 21 of the present invention, and a keyway structure can also be set between the second sleeve 42 and the second rotating shaft 32. The keyway structure can prevent circumferential rotation between the sleeve and the rotating shaft.

[0070] The present invention can quickly connect the first sleeve 41 and the second sleeve 42 via the first locking member 43. The first locking member 43 and the first sleeve 41 and the second sleeve 42 can be connected by bolts. Of course, designers can also use a snap-fit ​​structure to quickly connect the first locking member 43 and the first sleeve 41 and the second sleeve 42, which is not limited here.

[0071] In an embodiment of the present invention, the gas tank potential energy power generation system also includes a winch device 5, which is arranged on the piston 11. A second coupling structure 6 is provided between the winch device 5 and the winding device 2, and the winch device 5 is detachably connected to the winding device 2 through the second coupling structure 6.

[0072] By connecting the hoisting device 5 to the reeling device 2 via the second coupling structure 6, the hoisting device 5 can drive the reeling device 2 to reel in the connecting member 9. By locking the second coupling structure 6 to connect the hoisting device 5 to the reeling device 2, the hoisting device 5 can drive the reeling device 2 to rotate synchronously, thereby reeling in the connecting member 9 between the counterweight 12 and the reeling device 2, preventing the connecting member 9 from falling and affecting the use of the reeling device 2.

[0073] The hoisting device 5 can also be used to assist in lifting the counterweight 12. For example, during low power consumption periods, to improve power utilization, the second coupling structure 6 can be locked to connect the hoisting device 5 to the reeling device 2. The hoisting device 5 can then be used to lift the counterweight 12, converting electrical energy into gravitational potential energy of the counterweight 12 for storage.

[0074] For details, please refer to Figure 7 and Figure 9 The hoisting device 5 includes a hoist 51 and a third rotating shaft 52 arranged on the hoist 51. The third rotating shaft 52 is detachably connected to the other end of the first rotating shaft 21 through the second coupling structure 6.

[0075] When the winch 51 is used to drive the winding device 2, the second coupling structure 6 is locked to connect the first rotating shaft 21 with the third rotating shaft 52, and the winch 51 drives the winding wheel 22 to rotate synchronously to wind up the connecting member 9 or lift the counterweight 12; or, the winch 51 is used to lock the winding wheel 22, and then the counterweight 12 is lifted by the piston 11.

[0076] In an embodiment of the present invention, the second coupling structure 6 includes a third sleeve 61 arranged at the other end of the first rotating shaft 21, a fourth sleeve 62 arranged on the third rotating shaft 52, and a second locking member 63 arranged between the third sleeve 61 and the fourth sleeve 62, and the second locking member 63 is detachably connected to the third sleeve 61 and the fourth sleeve 62.

[0077] By disposing a second locking member 63 between the third sleeve 61 and the fourth sleeve 62, the second coupling structure 6 can be unlocked by removing the second locking member 63. At this time, a gap remains between the third sleeve 61 and the fourth sleeve 62, which does not affect the normal operation of the winding device 2 and the power generation device 3.

[0078] Furthermore, in order to prevent relative rotation between the rotating shaft and the sleeve, a keyway structure can be set between the third sleeve 61 of the present invention and the first rotating shaft 21, and a keyway structure can also be set between the fourth sleeve 62 and the third rotating shaft 52. The keyway structure can prevent circumferential rotation between the sleeve and the rotating shaft.

[0079] The present invention allows for rapid connection of the third and fourth shaft sleeves 61 and 62 via the second locking member 63. Bolts may be used to connect the second locking member 63 to the third and fourth shaft sleeves 61 and 62. Alternatively, a snap-fit ​​mechanism may be used to rapidly connect the second locking member 63 to the third and fourth shaft sleeves 61 and 62, without limitation.

[0080] In an embodiment of the present invention, the gas tank potential energy power generation system further includes a limiting guide structure 7 , and the counterweight 12 is arranged on the gas tank 1 through the limiting guide structure 7 .

[0081] By arranging the counterweight 12 on the limiting guide structure 7 , the movement path of the counterweight 12 can be limited, thereby preventing the counterweight 12 from colliding with the gas tank 1 during the lifting process.

[0082] Specifically, the limiting guide structure 7 includes a guide rail 71 provided on the gas cabinet 1 and a guide member 72 movably provided on the guide rail 71. The guide member 72 is connected to the counterweight 12. Specifically, the guide rail 71 can be provided on the gas cabinet 1 in the vertical direction, allowing the counterweight 12 to move vertically along the guide rail 71, thereby facilitating the rapid increase and release of the gravitational potential energy of the counterweight 12.

[0083] A guide rail locking structure may be provided between the guide rail 71 and the guide member 72. When the counterweight 12 needs to be retained on the guide rail 71, the guide rail 71 and the guide member 72 are locked by the guide rail locking structure. The guide rail locking structure may be a bolt structure or an eccentric wheel locking structure, which is not limited here.

[0084] In an embodiment of the present invention, a pulley structure 8 is provided on the gas tank 1, through which a connector 9 is connected to the winding device 2 and the counterweight 12. Utilizing the pulley structure 8 can reduce wear on the connector 9 and prevent the counterweight 12 from accidentally falling due to breakage of the connector 9.

[0085] Further, see Figure 10 In order to lift the counterweight 12 more effortlessly, the pulley structure 8 may include a first fixed pulley 81, a second fixed pulley 82, and a movable pulley 83 arranged between the first fixed pulley 81 and the second fixed pulley 82. The first fixed pulley 81 and the second fixed pulley 82 are both arranged on the gas tank 1 through a bracket.

[0086] The connecting member 9 includes a first cable 91 and a second cable 92. One end of the first cable 91 is connected to the first fixed pulley 81, and the other end of the first cable 91 is connected to the winding device 2 through the second fixed pulley 82. The movable pulley 83 is movably arranged on the first cable 91, one end of the second cable 92 is connected to the movable pulley 83, and the other end of the second cable 92 is connected to the counterweight 12.

[0087] By disposing the movable pulley 83 between the first fixed pulley 81 and the second fixed pulley 82, the movable pulley 83 can generate a lever effect, thereby making it possible to lift the counterweight 12 more labor-saving. In particular, when the movable pulley 83 is used in conjunction with the hoisting device 5, the output power of the hoisting device 5 can be reduced, thereby reducing the cost of using the hoisting device 5.

[0088] In order to facilitate guiding the connecting member 9 from the winding device 2 to the movable pulley 83, the pulley structure 8 may further include a third fixed pulley 84. Specifically, the first fixed pulley 81, the second fixed pulley 82, and the third fixed pulley 84 may be arranged at the same height, wherein the third fixed pulley 84 may be arranged directly above the winding device 2 to guide the first cable 91 to the first fixed pulley 81 and the second fixed pulley 82.

[0089] Among them, reference Figure 1 As shown, when the piston 11 descends, the winding device 2 is locked by the winch device 5, and the counterweight 12 is lifted by the pulling force when the piston 11 descends, so that the counterweight 12 rises to the top of the guide rail 71 for storing gravitational potential energy, thereby completing the first working condition.

[0090] Reference Figure 2 As shown, when it is necessary to use the counterweight 12 to generate electricity, the winding device 2 and the power generation device 3 are connected, and the counterweight 12 is released. The counterweight 12 descends from the top of the guide rail 71 to the bottom of the guide rail 71, and then pulls the power generation device 3 to generate electricity, thereby completing the second working condition.

[0091] Reference Figure 3As shown, when the piston 11 is at the bottom of the gas tank 1, the winch device 5 can be connected to the winding device 2, and the winch device 5 can be used to pull up the counterweight 12, so that the counterweight 12 rises from the bottom of the guide rail 71 to the top of the guide rail 71 for storing gravitational potential energy, thereby completing the third working condition.

[0092] Reference Figure 4 As shown, when the piston 11 is at the top of the gas tank 1, the hoisting device 5 can be connected to the winding device 2, and the hoisting device 5 can be used to pull the counterweight 12 up, so that the counterweight 12 rises from the bottom of the guide rail 71 to the top of the guide rail 71. At this point, the guide rail 71 and the guide member 72 can be locked to keep the counterweight 12 at the top of the guide rail 71, completing the fourth working state. At this point, the connection between the counterweight 12 and the connecting member 9 can also be released. When power generation is required, the connecting member 9 can be reconnected to the counterweight 12.

[0093] Reference Figure 5 As shown, when the piston 11 is at the top of the gas tank 1, the counterweight 12 can be pulled up by the winch device 5 to store gravitational potential energy; when power generation is required, the counterweight 12 is released, and the counterweight 12 is used to pull the power generation device 3 to generate electricity, completing the fifth working condition.

[0094] When the gas tank potential energy power generation system of the present invention is used, during the process of storing or releasing gas in the gas tank 1, the piston 11 in the gas tank 1 will frequently move up and down under the action of the gas pressure. The present invention arranges the winding device 2 and the power generation device 3 on the piston 11, and utilizes the winding device 2 and the power generation device 3 to cooperate with each other to pull the counterweight 12 from the second potential energy state to the first potential energy state during the up and down movement of the piston 11, thereby increasing the gravitational potential energy of the counterweight 12. The present invention can convert the pressure potential energy of the gas acting on the piston 11 into the gravitational potential energy on the counterweight 12, thereby realizing the recovery process of the gas pressure potential energy. When power generation is required, the winding device 2 is coordinated with the power generation device 3, and the counterweight 12 is used to drive the power generation device 3 to generate electricity, thereby realizing the process of recycling the gas pressure potential energy, which plays a role in recycling energy, saving energy and reducing emissions.

[0095] Implementation Method 2

[0096] The embodiment of the present invention further provides a method for generating electricity using the gas tank potential energy power generation system described in embodiment 1, comprising the following steps:

[0097] Energy storage process: The piston 11 is used to pull the counterweight 12 to the first potential energy state, or the winch device 5 is used to pull the counterweight 12 to the first potential energy state, so as to store gravitational potential energy.

[0098] Power generation process: After the counterweight 12 is in the first potential energy state, the counterweight 12 is used to drive the winding device 2 to rotate, so that the counterweight 12 switches from the first potential energy state to the second potential energy state to release weight potential energy, and then drives the power generation device 3 to generate electricity.

[0099] Among them, the height of the counterweight 12 in the first potential energy state is greater than the height of the counterweight 12 in the second potential energy state. For example, when the counterweight 12 is at the top of the guide rail 71, the first potential energy state can be formed, and when the counterweight 12 is at the bottom of the guide rail 71, the second potential energy state can be formed. There is no restriction here.

[0100] In an embodiment of the present invention, the energy storage process specifically includes the following steps: locking the second coupling structure 6, unlocking the first coupling structure 4, so that the winding device 2 is connected to the winch device 5, controlling the winch device 5 to be in a stopped state, and using the piston 11 to drive the counterweight 12 to move to the first potential energy state to store gravitational potential energy.

[0101] Specifically, when gas is introduced into the gas cabinet 1, the piston 11 is lifted and raised by the potential energy of the gas pressure. At this time, the second coupling structure 6 is locked, the first coupling structure 4 is unlocked, and the piston 11 drives the counterweight 12 to rise and store gravitational potential energy.

[0102] Of course, as another alternative implementation of the energy storage process, the energy storage process specifically includes the following steps: locking the second coupling structure 6, unlocking the first coupling structure 4, so that the winding device 2 is connected to the winch device 5, and using the winch device 5 to drive the counterweight 12 to rise to the first potential energy state to store gravitational potential energy.

[0103] In an embodiment of the present invention, the power generation method further includes identifying the current power consumption of the power grid, and performing an energy storage process if the current power consumption of the power grid is in a power consumption valley.

[0104] At this point, the second coupling structure 6 is locked, the first coupling structure 4 is unlocked, and the hoisting device 5 is used to pull the counterweight 12 upward to store gravitational potential energy, thereby converting electrical energy into gravitational potential energy for storage in the counterweight 12. By using the hoisting device 5 to raise the counterweight 12 during power consumption troughs, the power utilization rate of the power grid can be improved and energy waste can be reduced.

[0105] In an embodiment of the present invention, the power generation process includes the following steps: unlocking the second coupling structure 6, locking the first coupling structure 4, connecting the winding device 2 to the power generation device 3, moving the counterweight 12 from a first potential energy state to a second potential energy state to release weight potential energy, and utilizing the counterweight 12 to drive the winding device 2 to rotate, thereby driving the power generation device 3 to generate electricity. Releasing the counterweight 12 drives the power generation device 3 to generate electricity, thereby converting the gravitational potential energy on the counterweight 12 into electrical energy for output.

[0106] In an embodiment of the present invention, the power generation method further includes identifying the current power consumption of the power grid, and performing the power generation process if the current power consumption of the power grid is at a peak.

[0107] By releasing the counterweight 12 to drive the power generation device 3 to generate electric energy for supplying the power grid during the peak of power consumption, the load capacity of the power grid can be improved.

[0108] The current power consumption of the power grid can be identified based on time periods. For example, a 24-hour day can be divided into two time periods: 8:00 to 22:00 is the peak power consumption period, and 22:00 to 8:00 the next day is the valley power consumption period.

[0109] Furthermore, based on power grid electricity consumption data feedback over a period of time, peak and valley periods can be determined to control the energy storage and power generation processes. Alternatively, based on real-time power grid usage data feedback, the peak and valley periods can be adjusted in a timely manner. Of course, other methods can also be used to determine peak and valley periods, which are not limited here.

[0110] In an embodiment of the present invention, multiple gas tank potential energy power generation systems can be networked for use. These systems can generate electricity collaboratively during peak power consumption periods, generating significant amounts of power for the grid. During low power consumption periods, grid power is used to drive the hoisting device 5 to lift the counterweight 12, converting this energy into gravitational potential energy. This reduces power waste in the grid and improves power utilization. Furthermore, during peak power consumption periods, the counterweight 12 is released to generate power for the grid, thus achieving peak-shaving and valley-filling.
