Technical Field

[0001] This application relates to the technical field of gravity energy storage, and particularly relates to a chain plate type material inlet and outlet height adjustment device and a gravity energy storage system. Background Art

[0002] Gravity energy storage is a method of storing energy using gravitational potential energy. Its basic principle is to lift gravity power generation blocks to a high place to store energy. When energy needs to be released, these gravity power generation blocks are then lowered to drive a generator to generate electricity.

[0003] There are various forms of lifting devices in gravity energy storage. Among them, the chain plate type continuous elevator is a continuous working vertical conveying device, which can be used for continuous lifting and conveying connection of goods between two floors. The specific structure of the chain plate type continuous elevator can be referred to in Chinese Patent CN119602499A. It has the advantage of a high duty cycle and can lift heavy objects with a relatively large mass as much as possible in a limited space (such as an abandoned mine).

[0004] However, the existing chain plate type continuous elevator can only continuously lift and convey between one inlet and one outlet, and cannot change the height of the inlet and outlet. If there are many floors, it is impossible to change the positions of the inlets and outlets between different floors, resulting in inflexible transportation of heavy objects.

Detailed implementation manners

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. The components of the embodiments of this application usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents the selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative efforts belong to the scope of protection of this application.

[0023] In the description of the embodiments of this application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship when the product of this application is usually placed.

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

[0024] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0025] In the description of the embodiments of this application, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", "connected" 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 directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] According to a first aspect of the present invention, a chain plate type material inlet and outlet height adjustment device is provided, as Figures 1 to 13 shown. This chain plate type material inlet and outlet height adjustment device is used for a gravity energy storage system, and this chain plate type material inlet and outlet height adjustment device can cooperate with a chain plate type continuous elevator to transport the following heavy object block 10. This chain plate type material inlet and outlet height adjustment device includes a main frame body 1 and a lift.

[0027] In the following description, reference will be made to Figures 1 to 13 the detailed structures of the main frame 1 of the chain plate type material inlet and outlet height adjustment device and the elevator will be specifically described. In addition, it should be noted that the chain plate type material inlet and outlet height adjustment device of the present application is matched with a chain plate type continuous elevator, and the principle of the chain plate type continuous elevator can be the prior art, for example, as introduced in Chinese Patent CN119602499A. The chain plate type continuous elevator can utilize the characteristics of the chain plate to realize the lifting of heavy object blocks under specific working conditions, and meet the requirement of high duty cycle (realize higher efficiency power generation or power storage in a limited space). However, the chain plate type elevator has the problem that the inlet and outlet positions cannot be adjusted, that is, the existing chain plate type continuous elevator can only transport the heavy object block 10 from a specific position to a specific position and cannot be adjusted. The chain plate type material inlet and outlet height adjustment device provided by the present application can realize the adjustment of the inlet and outlet positions of the heavy object block 10 while utilizing the principle of the chain plate type elevator. Therefore, the principle of the chain plate type continuous elevator in the present application is the same as that of the chain plate type elevator in Chinese Patent CN119602499A and will not be elaborated here. The difference between the two is that in order to realize the adjustment of the inlet and outlet positions of the heavy object block 10, the installation positions of the following sprocket body 4 are different. In addition, in the following description, for clarity, the entry and exit of the heavy object block 10 are taken as an example of the energy storage process in gravity energy storage, that is, the heavy object block 10 enters the chain plate type continuous elevator at the bottom (the inlet and outlet of the chain plate type continuous elevator here are correspondingly called the inlet), and the heavy object block 10 leaves the chain plate type continuous elevator at the top (the inlet and outlet of the chain plate type continuous elevator here are correspondingly called the outlet).

[0028] As Figures 1 to 8 shown in the embodiment, the chain plate type material inlet and outlet height adjustment device includes a main frame 1 and an elevator. The chain plate type continuous elevator is arranged on the main frame 1, and the elevator is arranged on the main frame 1 in a position adjustable manner. The chain plate type continuous elevator may include a first sprocket group 201, a second sprocket group 202 and a chain group. The first sprocket group 201 is arranged on the main frame 1, the second sprocket group 202 is arranged on the elevator, and the chain group surrounds the first sprocket group 201 and the second sprocket group 202. The first sprocket group 201 is a fixed sprocket, which is used to support and limit the chain group, so that the chain group can operate normally, and further realize the normal operation of the chain plate type elevator. The second sprocket group 202 is arranged on the elevator and moves together with the elevator, so that the chain plate in the chain plate type elevator can receive the heavy object block 10 at different positions. Here, reference can be made to Figure 12 and Figure 13 , Figure 12 wherein, the heavy object block 10 enters the chain plate type elevator at the first floor 901 and is transported to the third floor 903; Figure 13In this case, the heavy object block 10 also enters the chain plate elevator at the first floor 901, but Figure 13 the elevator at the top has adjusted its position so that the outlet of the chain plate elevator corresponds to the fourth floor 904, and then transports the heavy object block 10 to the fourth floor 904. In addition, during the process of adjusting the position of the elevator, the position of the first sprocket group 201 remains unchanged while the position of the second sprocket group 202 changes, so that the length of the chain group remains unchanged to ensure the normal operation of the chain plate elevator.

[0029] Through the cooperation of the main frame 1, the elevator and the chain plate continuous elevator, the chain plate continuous elevator can be applied to the working conditions of multiple floors to meet the use requirements of gravity energy storage; by adopting the chain plate elevator, the high-duty-cycle conveying efficiency of the chain plate elevator can be retained, and the efficiency of gravity energy storage can be improved; through the movable elevator, the inlet and outlet heights of the chain plate continuous elevator can be adjusted, so that gravity energy storage is more flexible, with strong adaptability and versatility, and can meet the transportation of the heavy object block 10 under different working conditions.

[0030] Preferably, as Figures 1 to 11 shown, in the embodiment, the elevator may include a lifting component, a guide rail component and a moving frame 8. The moving frame 8 is movably arranged on the main frame 1 through the guide rail component, and the moving direction is the vertical direction, so as to cooperate with the transportation mode of the chain plate continuous elevator. The lifting component is arranged on the main frame 1 and connected to the moving frame 8 to drive the moving frame 8 to move on the main frame 1. When it is necessary to change the inlet and outlet positions, the lifting component drives the moving frame 8 to move. Similarly, in order to cooperate with the transportation mode of the chain plate continuous elevator to meet the requirement that the inlet and outlet of the chain plate continuous elevator can follow the movement of the moving frame 8, therefore, the second sprocket group 202 is arranged on the moving frame 8. When the second sprocket group 202 moves with the moving frame 8, the position of the chain group will also change, but the overall length remains unchanged.

[0031] Preferably, as Figures 1 to 11As shown, in the embodiment, the lifting assembly may include a driving member 601, a transmission member 602, and a lifting member 603. The driving member 601 drives the lifting rod of the lifting member 603 to extend or retract through the transmission member 602, and the lifting rod of the lifting member 603 is connected to the bottom of the moving frame 8. Further, the guide rail assembly may include a slide rail 701 and a slider 702. The slide rail 701 is disposed on the outer wall of the main frame 1, and the slider 702 is disposed on the outer wall of the moving frame 8 facing the main frame 1. Through the cooperation of the slide rail 701 and the slider 702, the moving frame 8 can move along the main frame 1 in the vertical direction. Thus, the movement process of the elevator is as follows: The lifting assembly may be formed as a screw elevator, for example. Through the drive of the drive motor, i.e., the driving member 601, the transmission member 602 rotates, thereby driving the lifting member 603 to lift. When the lifting member 603 lifts, it drives the moving frame 8 to move, and the movement of the moving frame 8 is achieved through the cooperation of the slide rail 701 and the slider 702. In addition, in order to ensure the stability of the movement, the lifting member 603 may also be fixedly installed on the side wall of the main frame 1.

[0032] Preferably, as Figures 1 to 11 shown, in the embodiment, in order to enable the import and export of the chain plate continuous elevator to adjust their positions, the elevator includes a first elevator 301 and a second elevator 302. The first elevator 301 and the second elevator 302 are relatively disposed at both ends of the main frame 1, that is, corresponding to the import and export of the chain plate continuous elevator respectively.

[0033] Further, the chain plate continuous elevator may include a first end assembly and a second end assembly. The first end assembly and the second end assembly can be respectively understood as the components at the upper and lower ends of the chain plate continuous elevator (the components include part of the chain group and the corresponding sprocket body 4). The first end assembly and the second end assembly are respectively disposed on the first elevator 301 and the second elevator 302. Whether it is the first end assembly or the second end assembly, both of these two assemblies include a first sprocket group 201 and a second sprocket group 202. That is to say, although the chain group simultaneously surrounds the first sprocket group 201 and the second sprocket group 202 of the first end assembly and the first sprocket group 201 and the second sprocket group 202 of the second end assembly, in fact, during the adjustment process, the first end assembly and the second end assembly are relatively independent and can be adjusted separately so that the chain plate continuous elevator can separately adjust the import position at the bottom and the export position at the top.

[0034] Preferably, as Figures 3 to 8As shown, in the embodiment, in order to satisfy the stability when the chain plate type continuous elevator hoists the heavy object block 10, both the first sprocket wheel group 201 and the second sprocket wheel group 202 include a plurality of sprocket wheel bodies 4, and the chain group includes a plurality of chain bodies 5. In addition, according to different set positions, the sprocket wheel bodies 4 need to be additionally installed on the main frame body 1 and the moving frame body 8 through connecting rods, positioning seats, axle shafts or drive shafts, etc. Such a setting is known to those skilled in the art and is also the prior art in the chain plate type continuous elevator, so it will not be elaborated here. In addition, actually in the field of gravity energy storage, the arrangement of sprocket wheels and chains can have various different ways. Therefore, in this application, the specific set positions and the number of uses of the sprocket wheel bodies 4 and the chain bodies 5 on the main frame body 1 and the moving frame body 8 are not limited, and these are also known to those skilled in the art. The chain plate type material inlet and outlet height adjustment device of this application realizes the adjustment of the inlet and outlet through the fixed setting and following setting forms of the first sprocket wheel group 201 and the second sprocket wheel group 202. Therefore, the specific set positions and the number of uses of the sprocket wheel bodies 4 and the chain bodies 5 on the main frame body 1 and the moving frame body 8 will not be elaborated here.

[0035] Further, as Figure 10 shown, since the chain plate type continuous elevator has the usage characteristic of vertical hoisting, the sprocket wheel arrangements at the inlet and outlet of the chain plate type continuous elevator are different. In order to satisfy the height adjustment at different positions of the inlet and outlet, the outlet of the chain plate type continuous elevator is close to the first elevator 301. The moving frame body 8 of the first elevator 301 includes a three-layer structure 801. The three-layer structure 801 can include three cross beams arranged in the height direction, and each layer structure is provided with a sprocket wheel body 4. The chain body 5 is arranged around the sprocket wheel body 4 of the three-layer structure 801. In addition, referring to Figure 7 , Figure 7 the chain body 5 at the lowermost sprocket wheel body 4 in

[0036] is arranged to have two opposite U shapes. On the one hand, it can ensure the stability of the chain body 5 when the moving frame body 8 moves. On the other hand, after the moving frame body 8 moves, it can always ensure that there is sufficient connectivity between the chain body 5 and the sprocket wheel body 4 and will not fall off due to this movement. At the same time, it can also correspondingly adjust the change in the length of the chain body 5 at different positions brought about by the movement of the moving frame body 8.

[0036] Preferably, as Figures 3 to 8 and Figure 11As shown, in the embodiment, the inlet of the chain plate type continuous elevator is close to the second elevator 302. The moving frame 8 of the second elevator 302 includes a single-layer structure 802. The single-layer structure 802 may include a cross beam arranged in the height direction. The single-layer structure 802 is provided with a sprocket body 4, and the chain body 5 is arranged around the sprocket body 4 of the single-layer structure 802. Since the inlet of the chain plate type continuous elevator is located at the bottom and not too many sprocket bodies 4 are required here to meet the operation, the moving frame 8 formed as the single-layer structure 802 can meet the requirement of position adjustment. Correspondingly, referring to Figure 4 and Figure 8 , after the moving frame 8 moves, the moving frame 8 will be far away from the bottom frame of the main frame body 1, and the sprocket body 4 of the first sprocket group 201 is arranged on the bottom frame of the main frame body 1. Thus, even if the moving frame 8 moves, the change in the length of the chain body 5 at different positions caused by the movement of the moving frame 8 can be adjusted accordingly.

[0037] Preferably, as Figures 3 to 8 shown, in the embodiment, the main frame body 1 includes a chain fixing layer 104. The first sprocket group 201 is arranged on the chain fixing layer 104, and both ends of the chain group are arranged around the first sprocket group 201 of the chain fixing layer 104. The top and bottom of the main frame body 1 are both provided with a chain fixing layer 104, and each chain fixing layer 104 is provided with a sprocket body 4 for the chain group to surround.

[0038] Preferably, as Figure 1 shown, in the embodiment, the main frame body 1, the elevator and the chain plate type continuous elevator all include a first part 105 and a second part 106 which are symmetrically arranged with each other. In order to ensure the stability of the operation of the chain plate type continuous elevator, the chain plate type material inlet and outlet height adjustment device is formed into a left-right symmetric structure, and the chain plate can move between the first part 105 and the second part 106 to transport the heavy object block 10.

[0039] Preferably, as Figures 7 to 9As shown, in the embodiment, the main frame 1 may include a bottom frame 103, a top frame 101, and an intermediate frame 102. The intermediate frame 102 is disposed between the bottom frame 103 and the top frame 101. A guide member 107 is provided on the intermediate frame 102, and the guide member 107 abuts against the chain group. The first elevator 301 and the second elevator 302 are respectively provided on the top frame 101 and the bottom frame 103. The height of the intermediate frame 102 can be selected according to the height of the usage scenario. For example, when the building is relatively high, more intermediate frames 102 are applied so that the top frame 101 and the bottom frame 103 can respectively correspond to the corresponding entrances and exits. Since no sprocket body 4 is provided at the intermediate frame 102, in order to ensure the stable operation of the chain body 5, a plurality of long strip-shaped guide members 107 are provided inside the intermediate frame 102. The guide member 107 can be, for example, an angle steel, and the chain body 5 can abut against the guide member 107 to obtain auxiliary support.

[0040] In addition, the connection methods, setting methods, and fixing methods not mentioned above can all be welding or threaded connection. Those skilled in the art can make specific selections according to needs, and will not be elaborated here.

[0041] Take Figure 12 and Figure 13 as an example. The operation process of the chain plate type material inlet and outlet height adjustment device is described by taking the energy storage process in gravity energy storage: First, the inlet of the chain plate type continuous elevator corresponds to the first floor 901 of the building, and the height of the chain plate is made consistent with that of the power conveyor on the first floor 901. The power conveyor on the first floor 901 conveys the heavy object block 10 to the chain plate at the inlet of the chain plate type continuous elevator. After that, the chain plate type continuous elevator drives the chain plate through the cooperation of the sprocket body 4 and the chain body 5, and lifts the heavy object block 10 to the outlet of the chain plate type continuous elevator. Then, the height of the outlet of the chain plate type continuous elevator is made consistent with that of the third floor 903 of the building, and the chain plate at the outlet of the chain plate type continuous elevator conveys the heavy object block 10 to the power conveyor on the third floor 903. Continuing like this, the heavy object block 10 is continuously conveyed from the first floor 901 to the third floor 903, realizing continuous energy storage.

[0042] Furthermore, when the heavy object block 10 needs to be transported to the fourth floor 904 of the building, the first elevator 301 continuously lifts the outlet of the chain plate type continuous elevator to the same height as the fourth floor 904, and makes the chain plates at the outlet of the chain plate type continuous elevator be at the same height as the power conveyor on the fourth floor 904. After that, it is selected whether the second elevator 302 operates according to needs. If it operates, that is, the inlet of the chain plate type continuous elevator is adjusted to be at the same height as the second floor 902 through the second elevator 302. If not, the inlet of the chain plate type continuous elevator still remains at the same height as the first floor 901. The chain plate type continuous elevator drives the chain plates through the cooperation of the sprocket body 4 and the chain body 5, and lifts the heavy object block 10 to the outlet of the chain plate type continuous elevator. Continuing like this, the heavy object block 10 is continuously transported from the first floor 901 to the fourth floor 904, realizing continuous energy storage.

[0043] Through the cooperation of the main frame body, the elevator and the chain plate type continuous elevator, the chain plate type continuous elevator can be applied to the working conditions of multiple floors to meet the use requirements of gravity energy storage; by adopting the chain plate type elevator, the high-duty-cycle conveying efficiency of the chain plate type elevator can be retained, and the efficiency of gravity energy storage can be improved; through the movable elevator, the inlet and outlet heights of the chain plate type continuous elevator can be adjusted, so that the gravity energy storage is more flexible, with strong adaptability and versatility, and can meet the transportation of heavy object blocks under different working conditions.

[0044] In addition, according to the second aspect of the present invention, a gravity energy storage system is provided, and the gravity energy storage system includes the chain plate type material inlet and outlet height adjustment device as described above. During the use of this gravity energy storage system, it can not only have the high duty cycle and transportation efficiency of the chain plate type elevator, but also realize the position adjustment of the inlet and outlet of the chain plate type elevator.

[0045] Finally, it should be noted that: the above-described embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting it. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed by the present application can still modify the technical solutions recorded in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
