[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] As attached Figure 1 To Attachment Figure 6 As shown:

[0039] Embodiment 1: This embodiment provides a self-circulating gravity system power storage and power generation device and method, including a main body 1, including a mountain 101, and a sliding plate 102 arranged on the slope of the mountain 101; a power storage and power generation mechanism 2, including a generator set 201 arranged on the top of the mountain 101, a multi-station coaxial gearbox 202 arranged at the input end of the generator set 201, an input shaft 203 arranged at the input end of the multi-station coaxial gearbox 202, a transmission wheel 204 arranged on the top of the sliding plate 102, four gravity plates 206 slidably arranged on the sliding plate 102, and a power storage and power generation mechanism 2. A rope 205 between the gravity plate 206 and the input shaft 203, a detection and control component 208 arranged on the sliding plate 102, and a pull-back reset component 207 arranged between the rope 205 and the input shaft 203; a safety protection mechanism 3, including a limit guide component 301 arranged between the sliding plate 102 and the gravity plate 206, a disassembly and assembly connection component 302 arranged on the limit guide component 301, and an anti-fall safety component 303 arranged on the limit guide component 301, wherein the sliding plate 102 can be replaced with a slide rail corresponding to the roller 3014.

[0040] Specifically, the pull-back reset assembly 207 includes a detection sensor 2083 disposed at the center of the sliding plate 102 , an electric push rod 2081 disposed at the top of the sliding plate 102 , and a blocking rod 2082 disposed at the output end of the electric push rod 2081 .

[0041] Specifically, the detection sensor 2083 corresponds to the gravity plate 206 , and two groups of blocking rods 2082 are provided, and the two groups of blocking rods 2082 are respectively located on both sides of the gravity plate 206 .

[0042] Specifically, the detection control component 208 includes a one-way bearing 2072 arranged between the rope 205 and the input shaft 203, a gear 2073 arranged on the outer ring of the one-way bearing 2072, a gear shaft 2074 arranged on the top of the mountain 101, and a motor 2071 arranged at the input end of the gear shaft 2074.

[0043] Specifically, gear 1 2073 is meshed with the gear shaft 2074 , and the top of the transmission wheel 204 is in contact with the rope 205 .

[0044] Specifically, the limiting guide assembly 301 includes a plurality of limiting guide rails 3011 arranged on the sliding plate 102, an axle rod 3013 arranged inside the gravity plate 206, a plurality of groups of rollers 3014 arranged on the axle rod 3013, and side limiting wheels 3012 arranged on both sides of the gravity plate 206; the limiting guide rails 3011 are adapted to the movement trajectory of the side limiting wheels 3012, the rollers 3014 penetrate the gravity plate 206 and contact the sliding plate 102, and when the gravity plate 206 slides downward, the side limiting wheels 3012 will slide in the limiting guide rails 3011, thereby reducing the movement resistance of the gravity plate 206 and limiting the position of the gravity plate 206, thereby controlling the sliding route of the gravity plate 206 to be certain.

[0045] As can be seen from the above, before the device works, redundant AC power can be used to power motor 1 2071, and motor 1 2071 will drive gear shaft 2074 to rotate, and then drive one-way bearing 2072 to rotate forward through the engagement of gear shaft 2074 and gear 1 2073, so as to reel in rope 205 and pull gravity plate 206 toward the top of mountain 101 until gravity plate 206 moves over blocking rod 2082 to the specified position at the top of mountain 101, then start electric push rod 2081, push blocking rod 2082 to move to the bottom of gravity plate 206, so as to block the position of gravity plate 206 and prevent gravity plate 206 from slipping, and turn off motor 1 2071. Motor 1 2071 adopts a motor with a non-brake structure. When motor 1 2071 is powered off, its shaft can rotate naturally. When the city electricity is insufficient and power generation is required, the electric push rod 2081 corresponding to the first gravity plate 206 is started to drive the resistance rod 2082 to pull back and contact the limit of the position of the gravity plate 206. The gravity plate 206 will slide downward on the sliding plate 102 using the roller 3014 under the action of its own weight. During the sliding process, the rope 205 wound on the one-way bearing 2072 will be pulled, thereby driving the one-way bearing 2072 to rotate in the opposite direction. When the one-way bearing 2072 rotates in the opposite direction, it will drive the input shaft 203 to rotate synchronously. The input shaft 203 will drive the generator set 201 to rotate rapidly after the multi-station coaxial gearbox 202 changes speed, so as to convert the gravitational potential energy of the gravity plate 206 into electrical energy, which is input into the national power grid after being processed by an external step-up transformer to ensure voltage stability, thereby completing power generation;

[0046] The current detection sensor 2083 corresponds to the electric push rod 2081 corresponding to the next group of gravity plates 206. When the first gravity plate 206 slides to the detection sensor 2083, it will be detected by the detection sensor 2083, and then the electric push rod 2081 corresponding to the second gravity plate 206 will be released to release the position limit of the gravity plate 206. The second gravity plate 206 will slide down to generate electricity. When the second gravity plate 206 moves to the detection sensor 2083, the position limit of the third gravity plate 206 will be released, and at this time the first gravity plate 206 will slide to At the lowest point of the sliding plate 102, start the corresponding motor 2071, repeat the above work to pull the gravity plate 206 back to the initial position at the top of the sliding plate 102, and use the electric push rod 2081 to restore the limit on its position, so that when the fourth gravity plate 206 moves to the detection sensor 2083, the limit is released, and cyclic power generation is carried out. During the power generation process, there are always two gravity plates 206 in a sliding operation state, and the power generation is cyclically generated at a uniform speed to ensure the power generation efficiency. It can be input into the national power grid for power supply, avoiding the situation where a large amount of electricity is generated at one time and causing a waste of electricity.

[0047] Embodiment 2: This embodiment is basically the same as the previous embodiment, with the difference that the disassembly and assembly connection assembly 302 includes a mounting plate 3021 arranged between the limit guide rail 3011 and the sliding plate 102, and a connecting plate 3022 arranged between the limit guide rails 3011. A sliding rail composed of several limit guide rails 3011 is used. When a local limit guide rail 3011 is damaged, it can be separated from the adjacent limit guide rail 3011 by using the connecting plate 3022, and then it can be removed by using the mounting plate 3021, so that personnel can carry out local replacement and maintenance conveniently, reduce maintenance costs, and facilitate personnel to use.

[0048] Specifically, the anti-fall safety component 303 includes tooth plates 3039 arranged on both sides of the gravity plate 206, a movable plate 3035 arranged on the tooth plate 3039, movable seats 3036 arranged on both sides of the gravity plate 206, an insertion rod 3037 arranged on the outside of the movable seat 3036, a plurality of through holes 3032 arranged on the limiting guide rail 3011, a spring 3038 arranged between the movable plate 3035 and the movable seat 3036, a motor 2 3033 arranged on the top of the gravity plate 206, and a gear 2 3034 arranged at the output end of the motor 2 3033.

[0049] Specifically, the second gear 3034 is meshed with the tooth plate 3039 , the insertion rod 3037 is matched with the through hole 3032 , and a buffer seat 3031 is provided on the sliding plate 102 at the bottom of the gravity plate 206 .

[0050] As can be seen from the above, when the gravity plate 206 slides to the lowest point of the sliding plate 102, the gravity plate 206 will be buffered and decelerated by the buffer seat 3031;

[0051] When the rope 205 is accidentally disconnected during the sliding of the gravity plate 206, the motor 2 3033 is automatically started, and the motor 2 3033 drives the gear 2 3034 to rotate. The gear 2 3034 is connected with the tooth plate 3039 to drive the two movable plates 3035 to move to the two sides of the gravity plate 206 respectively, and then the movable seat 3036 is pushed by the spring 3038 together with the plug rod 3037 thereon to move together until the plug rod 3037 hits the limit guide rail 3011. When the plug rod 3037 is not aligned with the through hole 3032 and When motor 2 3033 continues to work, movable seat 3036 cannot move, while movable plate 3035 continues to move toward both sides of gravity plate 206, thereby compressing spring 3038 and accumulating elastic potential energy. When the insertion rod 3037 is aligned with through hole 3032, spring 3038 will release elastic potential energy due to the disappearance of resistance, so as to push the insertion rod 3037 into through hole 3032, thereby utilizing limit guide rail 3011 to slow down and limit the position of gravity plate 206, so as to facilitate subsequent maintenance and adjustment by staff and improve the safety of the device.

[0052] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that it is a method for storing and generating electricity in a self-circulating gravity system, and the specific steps are as follows:

[0053] S1: In the initial state, all four gravity plates 206 are moved to the top of the sliding plate 102;

[0054] S2: releasing the limitation on the position of the first gravity plate 206 by controlling the button;

[0055] S3: The first gravity plate 206 slides downward under the action of gravity, and uses the rope 205 to drive the input shaft 203 to rotate, and after the multi-station coaxial gearbox 202 changes speed, it drives the generator set 201 to rotate, converting the gravity potential energy into electrical energy;

[0056] S4: When the first gravity plate 206 moves to the detection sensor 2083, the position restriction of the second gravity plate 206 is released, and the third and fourth gravity plates 206 are similarly removed;

[0057] S5: When the third gravity plate 206 slides downward, the first gravity plate 206 falls to the lowest point of the sliding plate 102, and the motor 1 2071 is started to drive the one-way bearing 2072 to rotate in the opposite direction to reel in the rope 205;

[0058] S6: When the fourth gravity plate 206 slides downward, the first gravity plate 206 is pulled back to the highest point of the sliding plate 102, and the second, third, and fourth gravity plates 206 are pulled back in the same manner;

[0059] S7: When the fourth gravity plate 206 moves to the detection sensor 2083, the position limitation of the first gravity plate 206 is released to realize a uniform power generation cycle.

[0060] This design application is applied to the scenario of power storage and power generation, and proposes to use the gravity plate 206 to perform up and down reciprocating motion within the vertical range of the slope or artificial building to generate potential energy and related power generation technology. At the same time, it also covers the technology of using two or more gravity plates 206 to perform reciprocating potential energy motion and perform work through the multi-station coaxial gearbox 202. In addition, the device also includes the power generation technology of the coaxial gearbox of two or more stations;

[0061] Specifically, the motor 2071 is powered during the redundancy of the mains power supply, the gravity plate 206 is pulled to the top of the mountain 101, the electrical energy is converted into gravitational potential energy and stored, and the restriction on the gravity plate 206 is released when power is insufficient and power generation is needed, the gravity plate 206 falls down to drive the shaft of the generator set 201 to rotate, and the gravitational potential energy is converted into electrical energy for power generation, and a number of gravity plates 206 are set, and when the current gravity plate 206 slides to the middle of the slope of the mountain 101, the restriction on the position of the next gravity plate 206 is released, and when the gravity plate 206 falls to the lowest point of the mountain 101, it is pulled back to the top of the mountain 101 to achieve uniform and continuous cycle power generation, ensure a certain power generation efficiency, avoid waste caused by a large amount of electrical energy overflow at one time, and avoid waste of time, without being affected by local natural resources and the environment.
