DETAILED DESCRIPTION

[0033] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0034] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the application is usually placed when in use.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0035] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0036] In the description of the embodiments of the present application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] According to the present invention, a single-channel gravity energy storage circulation device is provided, such as Figures 1 to 13 As shown, the gravity energy storage single channel circulation device can make the weight block 6 circulate back and forth in the single channel gravity energy storage device. The gravity energy storage single channel circulation device includes an energy storage system 1, a power generation system 2, a guide rail system and a weight block 6.

[0038] In the following description, reference will be made to Figures 1 to 13 The detailed structures of the energy storage system 1, the power generation system 2, the guide rail system and the weight block 6 of the gravity energy storage single-channel circulation device are specifically described.

[0039] In an embodiment, Figure 2 It is a schematic diagram of the present invention, in which the direction pointed by the vertical arrow is the direction of movement of the weight block 6, and the direction indicated by the rotating arrow is the direction of rotation of the following wheel body 703. It can be understood that based on the basic principle of gravity energy storage, the main functions in the gravity energy storage device are split, and the energy storage and power generation functions are realized through the two processes of lifting and releasing the weight, namely, the energy storage system 1 and the power generation system 2 respectively. In the process of energy storage, multiple weight blocks 6 are continuously lifted to a certain height for storage, and the whole process is similar to the escalator movement; in the process of energy release, the weight block 6 is continuously and stably worked under the action of gravity, and converted into continuous torque to drive the power generation equipment, and the process is similar to the movement of a waterwheel. Based on the escalator movement and the waterwheel movement, the two are connected by a guide rail system, so that the weight block 6 can circulate between the two systems, and then there is no need to set up other devices, that is, the reciprocating circulation of the weight block 6 in the single-channel gravity energy storage device can be realized.

[0040] Specifically, Figure 1 As shown, in the embodiment, the weight block 6 of the present invention adopts a spherical structure. The spherical structure has good movement characteristics. The movement scheduling of the weight can be achieved through a simple slope track, and there is no need to install additional machinery and equipment to carry the weight block 6.

[0041] Further, in the embodiment, both the energy storage system 1 and the power generation system 2 may include a loading mechanism 3 and an unloading mechanism 4. Since it is necessary to ensure that the heavy block 6 can circulate in both the energy storage system 1 and the power generation system 2, both systems need to have loading and unloading capabilities to facilitate the lifting and release of the heavy block 6. In order to connect the two loading mechanisms 3 and the two unloading mechanisms 4, the guide rail system includes a first guide rail 501 and a second guide rail 502. The unloading mechanism 4 of the energy storage system 1 is connected to the loading mechanism 3 of the power generation system 2 through the first guide rail 501, and the loading mechanism 3 of the energy storage system 1 is connected to the unloading mechanism 4 of the power generation system 2 through the second guide rail 502.

[0042] Furthermore, the first guide rail 501 and the second guide rail 502 may both include an inclined portion 503, and when the spherical weight block 6 moves on the first guide rail 501 and the second guide rail 502, it can be affected by gravity and move along the guide rails, thereby moving from one loading mechanism 3 to another corresponding unloading mechanism 4, or from one unloading mechanism 4 to another loading mechanism 3. The loading mechanism 3 and the unloading mechanism 4 can load the weight block 6 and unload the weight block 6 respectively.

[0043] The single-channel gravity energy storage circulation device can realize the reciprocating motion of the weight block 6 between the two systems through the cooperation of the energy storage system 1, the power generation system 2 and the guide rail system, thereby realizing the circulation of the weight block 6 of the single-channel gravity energy storage device, and improving the energy conversion rate while reducing energy consumption; through the specially customized spherical weight block 6, the spherical weight block 6 can be affected by gravity and slide on the guide rail system including the inclined portion 503, so that the single-channel gravity energy storage circulation device has a simple overall structure, a small footprint, and less installed equipment, and the overall circulation is smooth, which improves the operating efficiency and effectively solves the problem that the existing single-channel gravity energy storage device cannot achieve cyclic continuous operation.

[0044] Preferably, if Figure 1 , Figures 3 to 8 As shown, in the embodiment, the loading mechanism 3 and the unloading mechanism 4 of the energy storage system 1 and the loading mechanism 3 and the unloading mechanism 4 of the power generation system 2 are connected by a wheel mechanism. The wheel mechanism includes a hanging basket chain 702 and a wheel body 703, and the wheel body 703 is arranged at the end of the first guide rail 501 and the end of the second guide rail 502. In the embodiment, the number of the wheel bodies 703 is four, and the four wheel bodies 703 correspond to two loading mechanisms 3 and two unloading mechanisms 4 respectively. A wheel body 703 is installed at both ends of the first guide rail 501 and the two ends of the second guide rail 502. In this way, the gravity energy storage single-channel circulation device as a whole can be approximately rectangular, and the overall structure of the rectangular gravity energy storage single-channel circulation device is compact and easy to arrange. And the energy storage system 1 and the power generation system 2 can be understood as a module in the rectangular gravity energy storage single-channel circulation device, which is also convenient for early installation and later maintenance.

[0045] Furthermore, the two rotating wheel bodies 703 of the energy storage system 1 and the two rotating wheel bodies 703 of the power generation system 2 are respectively connected by a hanging basket chain 702, and the hanging basket chain 702 can be composed of multiple hanging basket bodies 701 connected end to end. The connection form between the rotating wheel body 703 and the hanging basket chain 702 can be similar to the connection form between a bicycle gear and a bicycle chain. When the bicycle gear (rotating wheel body 703) rotates, it can drive the bicycle chain (hanging basket chain 702) to move. Since the multiple hanging basket bodies 701 are connected to each other in a hinged manner, when the hanging basket chain 702 moves, the hanging basket body 701 will also change position.

[0046] Preferably, if Figure 3 , Figure 4 and Fig.13 As shown, in the embodiment, the loading mechanism 3 may include a loading auxiliary member 8, and the loading auxiliary member 8 is rotatably disposed at one end of the guide rail system close to the rotating wheel body 703. Figure 3 and Figure 4For example, the loading aid 8 is rotatably arranged at the lower part of the first guide rail 501. The rotatable arrangement method can be, for example, a rotation point is arranged at the lower part of the first guide rail 501, and is connected to the rotation point of the loading aid 8 through a connecting shaft, so that the loading aid 8 can rotate with the rotation point as the rotation center.

[0047] Furthermore, the loading auxiliary member 8 may include a receiving groove 801, a blocking end 802 and a rotation driving handle 803. In an embodiment, the loading auxiliary member 8 may be formed into a structure approximately in the shape of a spoon. The spoon-shaped structure can be used to receive the weight block 6, and at the same time drive the weight block 6 to slide along the first guide rail 501 and enter the hanging basket body 701 along a specified direction. Specifically, the receiving groove 801 may be the spoon portion of a spoon. The receiving groove 801 may be formed into a circular groove, and the circular groove may correspond to the spherical weight block 6. In horizontal projection (such as Figure 3 and Figure 4 As shown), the blocking ends 802 are located at both ends of the receiving groove 801, and the blocking ends 802 can be used to prevent the weight block 6 from escaping from the receiving groove 801. Preventing escaping here should be understood as: after the weight block 6 enters the receiving groove 801, the loading auxiliary component 8 rotates, and at this time the blocking ends 802 can prevent the weight block 6 from returning along the original path. The rotating driving handle 803 extends into the rotating wheel body 703. The extension here refers to the horizontal projection. In actual use, the rotating driving handle 803 can be on the side of the rotating wheel body 703. The two will not interfere with each other. The rotating driving handle 803 can have two functions. The first function is to limit the movement path of the weight block 6 so that the weight block 6 can only move from the accommodating groove 801 to the hanging basket body 701. The second function is when the following toggle rod 706 approaches and abuts against the rotating driving handle 803, since the toggle rod 706 is always subjected to the rotational force of the rotating wheel body 703, it can drive the rotating driving handle 803 to rotate, so that the loading auxiliary part 8 is tilted, and then the weight block 6 located on the loading auxiliary part 8 will be affected by gravity and move to the hanging basket body 701.

[0048] Preferably, if Figure 3 , Figure 4 and Fig.13 As shown, in the embodiment, when the weight block 6 enters the accommodating groove 801 along the first guide rail 501 , in order to avoid wear and reduce power loss, a sliding wheel 804 is provided at the top of the blocking end 802 in contact with the weight block 6 .

[0049] Preferably, if Figures 3 to 5 , Fig.11 and Fig.12As shown, in the embodiment, the wheel body 703 includes a plurality of rotating edges 704, each rotating edge 704 is connected in sequence from head to tail, and the connection point of two adjacent rotating edges 704 is a hinge point 705, and the hinge point 705 can be used for the installation of the hanging basket body 701, and the installation method is a hinge connection, specifically, the cooperation of the connecting shaft and the bearing can be used. The two ends of the hanging basket body 701 are respectively arranged at a hinge point 705, which can also be understood as one rotating edge 704 can correspond to one hanging basket body 701.

[0050] Preferably, if Figure 3 and Figure 4 As shown, in the embodiment, the hanging basket body 701 may include a loading position 7014, which can accommodate a heavy object block 6, and each rotating edge 704 is provided with a toggle rod 706. When the rotating wheel body 703 rotates, the toggle rod 706 can abut against the rotating driving handle 803 to drive the loading auxiliary member 8 to rotate, and the heavy object block 6 located in the accommodating groove 801 moves to the loading position 7014. The loading position 7014 can be understood as the basket of the hanging basket body 701. The hanging basket body 701 itself can be made of metal materials such as steel and iron, and has a certain strength.

[0051] Preferably, if Figure 3 and Figure 4 As shown, in the embodiment, the loading assistant 8 may further include a first reset portion 805, a first end of the first reset portion 805 is connected to the guide rail system, and a second end of the first reset portion 805 is connected to the rotation driving handle 803. The first reset portion 805 may be, for example, a tension spring, and when the rotation driving handle 803 is pushed by the toggle rod 706, the tension spring is stretched, and after the toggle rod 706 is separated from the rotation driving handle 803, the tension spring is reset, thereby resetting the loading assistant 8.

[0052] Preferably, if Figures 6 to 8 As shown, in the embodiment, the first end of the hanging basket body 701 is provided with an outer hinge 7011, and the second end of the hanging basket body 701 is provided with an inner hinge 7012. The outer hinge 7011 of one hanging basket body 701 is connected to the inner hinge 7012 of the adjacent hanging basket body 701 through a first rotating shaft 7013. Two adjacent hanging basket bodies 701 are connected through the first rotating shaft 7013, and the connection points of the two adjacent hanging basket bodies 701 can slide against each other. The first rotating shaft 7013 can also be hinged with the hinge point 705 of the rotating wheel body 703, and then through the rotation of the rotating wheel body 703, the hanging basket chain 702 is driven to change position. The hinged manner can be understood as the connection form of the bicycle chain and the gear mentioned above, which will not be repeated here.

[0053] Preferably, if Figure 5As shown, in the embodiment, the hanging basket body 701 may further include a second reset portion 7015, which is disposed inside the loading position 7014. When the weight block 6 is disposed at the loading position 7014, the second reset portion 7015 abuts against the weight block 6. The second reset portion 7015 may be a tension spring, which is in a naturally extended state before the weight block 6 enters the loading position 7014. When the weight block 6 is disposed at the loading position 7014, the tension spring is compressed by the weight block 6. Figure 5 In the unloading state shown, since the gravity of the weight block 6 is dispersed, the elastic force of the tension spring is greater than the gravity at this time, and the tension spring is reset, thereby pushing the weight block 6 toward the inclined portion 503.

[0054] Preferably, if Figures 3 to 5 As shown, in the embodiment, the hanging basket body 701 can be in the loading state ( Figure 3 and Figure 4 is loaded state) and unloaded state ( Figure 5 When the basket body 701 passes through the rotating wheel body 703 of the loading mechanism 3 and approaches the guide rail system, the basket body 701 is in the loading state; when the basket body 701 passes through the rotating wheel body 703 of the unloading mechanism 4 and approaches the guide rail system, the basket body 701 is in the unloading state; when the basket body 701 is in the loading state, one end of the loading position 7014 is flush with the guide rail system (see Fig.13 ), when the basket body 701 is in the unloading state, the opening of the loading position 7014 faces the guide rail system (see Figure 5 ).

[0055] Preferably, if Figure 1 , Figures 3 to 5 As shown, in the embodiment, the first guide rail 501 and the second guide rail 502 also include a straight portion 504, and the ends of the first guide rail 501 and the second guide rail 502 close to the unloading mechanism 4 are inclined portions 503, and the ends of the first guide rail 501 and the second guide rail 502 close to the loading mechanism 3 are straight portions 504. The inclined portions 503 are provided to facilitate the rolling of the weights 6, and the straight portions 504 are provided to prevent the weights 6 from colliding with each other due to a large number of the weights 6.

[0056] Preferably, if Fig. 9 and Fig.10 As shown, in an embodiment, the guide rail system may further include a lateral guide 505, which is disposed above the first guide rail 501 and the second guide rail 502 and on both sides of the weight block 6, thereby preventing the weight block 6 from falling off the first guide rail 501 and the second guide rail 502 and guiding the movement of the weight block 6.

[0057] Preferably, if Fig.11 and Fig.12 As shown, in the embodiment, a second rotating shaft 707 is provided in the middle of the rotating wheel body 703 , and the rotating wheel body 703 can rotate around the second rotating shaft 707 as a rotating point. A bracket 708 is also provided at the bottom of the rotating wheel body 703 to support the rotating wheel body 703 .

[0058] The motion process of the single-channel gravity energy storage circulation device is as follows: Since the entire device is a cycle, the description is based on the loading mechanism 3 of the power generation system 2 as the starting point. Fig.13 , a weight block 6 moves along the first guide rail 501 to the position where the loading auxiliary member 8 is located, and at this time, one end of the sliding wheel 804 of the loading auxiliary member 8 is flush with the first guide rail 501. The weight block 6 can be affected by the inertial force and enter the receiving groove 801, and the loading auxiliary member 8 is switched to Fig.13 The second state is the waiting state, after which the rotating wheel body 703 drives the toggle rod 706 to abut against the rotating driving handle 803 of the loading auxiliary component 8, and pushes the rotating driving handle 803 to rotate the loading auxiliary component 8. Due to the influence of gravity, the weight block 6 enters the hanging basket body 701. After the weight block 6 is separated from the loading auxiliary component 8 and the toggle rod 706 is separated from the rotating driving handle 803, the loading auxiliary component 8 is reset due to the pulling of the first reset part 805, waiting for the transportation of the next weight block 6. Afterwards, the hanging basket body 701 carrying the weight block 6 moves to the unloading mechanism 4 of the power generation system 2 as the hanging basket chain 702 moves. See. Figure 5 The position of the hanging basket body 701 moved to this place changes due to the influence of the rotating wheel body 703. When the opening of the hanging basket body 701 faces the second guide rail 502, the weight block 6 enters the inclined portion 503 of the second guide rail 502 due to the influence of gravity, and then enters the loading mechanism 3 of the energy storage system 1 through the straight portion 504. The loading mechanism 3 of the energy storage system 1 and the loading mechanism 3 of the power generation system 2 have the same operating principle, only the position is different, which will not be repeated here. The weight block 6 is driven by the hanging basket chain 702 and moves from the loading mechanism 3 of the energy storage system 1 to the unloading mechanism 4 of the energy storage system 1. At this time, see Figure 1 Due to the position limitation of the hanging basket chain 702, the unloading at this location is Figure 1 The left side of the unloading is performed, and the weight block 6 returns to the first guide rail 501 along the preset track, thereby completing the whole cycle.

[0059] The single-channel gravity energy storage circulation device can realize the reciprocating motion of the weight block between the two systems through the cooperation of the energy storage system, the power generation system and the guide rail system, thereby realizing the circulation of the weight block of the single-channel gravity energy storage device, and improving the energy conversion rate while reducing energy consumption; through the specially customized spherical weight block, the spherical weight block can be affected by gravity and slide on the guide rail system including the inclined part, so that the overall structure of the single-channel gravity energy storage circulation device is simple, the footprint is small, and the installed equipment is small, the overall circulation is smooth, the operating efficiency is improved, and the problem that the existing single-channel gravity energy storage device cannot realize cyclic continuous operation is effectively solved.
