Description

Technical Field

[0001] This utility model relates to the field of photovoltaic system technology, specifically to an energy storage booster component and a photovoltaic tracking device. Background Technology

[0002] In fields such as industrial manufacturing, mechanical engineering, and transportation, the motion of loads often exhibits periodic characteristics during the driving process. For example, in the reciprocating motion of a cantilever beam around its axis in a cantilever structure, when the center of gravity of the cantilever beam moves downward, it is a force-saving motion; when the center of gravity moves upward, it is a force-consuming motion. Therefore, the cantilever beam repeatedly undergoes alternating force-saving and force-consuming motions during its motion. The mechanical energy released during the force-saving phase is consumed in various forms, leading to energy waste. In recent years, with the development of green energy and efficient transmission technologies, issues related to energy recovery and reuse have become a research hotspot.

[0003] Currently, linear springs are commonly used as the core energy storage medium in the field of mechanical energy recovery. However, their inherent characteristics have obvious limitations. The energy storage mechanism of linear springs follows Hooke's Law, that is, the elastic force is proportional to the deformation (F=kx), which causes its output force to exhibit a linear characteristic with the deformation. This linear characteristic does not match the torque requirements of the cantilever beam, and mechanical energy cannot be fully recovered and used for the cantilever beam. To solve these problems, an energy storage assist component is proposed, which adjusts the curve of the output force acting on the cantilever beam through a cam.

[0004] When this energy storage and assist component is used in a cantilever structure, the curve of the force change acting on the cantilever beam and the curve of the torque demand of the cantilever beam are consistent, but the peak values ​​of the two are not at the same position. This can lead to problems such as energy transfer delay or energy loss, thereby affecting the working efficiency of the energy storage and assist component. Utility Model Content

[0005] The first objective of this invention is to provide an energy storage booster component to solve the problems of energy transfer delay and energy loss in existing energy storage booster components. The second objective of this invention is to provide a photovoltaic tracking device.

[0006] The present invention is achieved by the following technical solution:

[0007] As a first aspect of this utility model, an energy storage and assist component is used for a cantilever structure. The cantilever structure includes a support member, a rotating shaft, and a cantilever beam. The rotating shaft includes a central shaft and a movable outer cylinder. The central shaft is connected to the support member, and the movable outer cylinder is sleeved on the central shaft. The movable outer cylinder can rotate around the axis of the central shaft, and one end of the cantilever beam is connected to the movable outer cylinder.

[0008] Energy storage and booster components include:

[0009] A base, which is connected to the support member;

[0010] The elastic element includes a fixed end and a movable end, wherein the fixed end is connected to the support element.

[0011] The traction component includes a first traction component and a second traction component, with one end of the first traction component connected to the movable end;

[0012] The transmission unit includes a main shaft, a first cam, and a first transmission wheel. The main shaft is rotatably connected to a base. The first cam and the first transmission wheel are connected to the main shaft along its axis. The axis of the main shaft is perpendicular to the axis of the central shaft. The other end of the first traction member extends along the surface of the first cam and is connected to the first cam. One end of the second traction member extends along the surface of the first transmission wheel and is connected to the first transmission wheel.

[0013] The second drive wheel is connected to the movable outer cylinder along the axis of the movable outer cylinder, and the other end of the second traction member extends along the surface of the second drive wheel, with the extended end connected to the second drive wheel;

[0014] The guiding structure includes a guide wheel and an adjustment part. The guide wheel is connected to the support member and is used to guide the direction of the second traction member. The adjustment part is used to adjust the distance between the guide wheel and the main shaft.

[0015] Optionally, one side of the surface of the first drive wheel and one side of the surface of the guide wheel form a channel through which the second traction member passes in an axial direction perpendicular to the central axis.

[0016] Optionally, the adjustment unit drives the guide wheel to move along the length of the channel.

[0017] Optionally, the second traction element is a chain.

[0018] Optionally, the adjusting part includes a strip groove, an adjusting block, and an adjusting bolt. The strip groove is disposed on the base along the length direction of the channel. The adjusting block is connected to the guide wheel and disposed in the strip groove. The adjusting bolt is used to drive the adjusting block to move within the strip groove.

[0019] Optionally, the adjusting bolt is rotatably connected to the adjusting block, and the adjusting bolt is threadedly connected to the base;

[0020] Alternatively, the adjusting bolt is threadedly connected to the adjusting block, and the adjusting bolt is rotatably connected to the base.

[0021] Optionally, the base is provided with a U-shaped reserved groove, and the guide wheel is placed in the reserved groove.

[0022] Optionally, at least one side of the two side walls of the reserved groove is provided with the adjustment part.

[0023] Optionally, the axis of the guide wheel is parallel to the axis of the central shaft, and the guide wheel is positioned opposite the second transmission wheel along the axis of the central shaft.

[0024] As a second aspect of this utility model, a photovoltaic tracking device includes the energy storage assist component described above.

[0025] The advantages of this utility model are: it increases the stability of the cantilever structure, improves the working efficiency of the energy storage and assist component, makes the structure of the energy storage and assist component simpler and more efficient, and the adjustment part makes it simple and convenient to adjust the distance between the guide wheel and the main shaft.

[0026] First, under the action of the first cam, the deformation of the first elastic element and the force fed back to the main shaft in the energy storage assist component of this utility model exhibit a similar change state to the change state of the force used to resist the gravitational torque of the cantilever beam. Both first rise and then fall, with a peak value. By setting an adjustment part between the main shaft and the second transmission wheel, the adjustment part is used to adjust the distance between the guide wheel and the main shaft. During the adjustment of the distance between the guide wheel and the main shaft, under the action of the second traction member, the transmission part can be driven to rotate accordingly. Thus, the deformation state of the elastic element is changed by the first traction member, thereby adjusting the peak position of the elastic force fed back to the main shaft by the first elastic element, making it more matched with the state of the cantilever beam. This makes the peak position of the force used to resist the gravitational torque of the cantilever beam consistent with the peak position of the elastic force fed back to the main shaft by the first elastic element, making their curves further overlap. The energy storage assist component can more fully recover and store the energy generated by the gravitational potential energy when the cantilever beam rotates downward, and use it to assist the cantilever beam to rotate upward, further improving the working efficiency of the energy storage assist component.

[0027] Secondly, when adjusting the distance between the guide wheel and the main shaft through the adjustment part, the adjustment screw is rotated. Since the adjustment screw and the adjustment block form a threaded connection, the guide wheel is driven to move in the strip groove through the adjustment block, thereby adjusting the deformation state of the elastic element. The adjustment method is simple and convenient.

[0028] Third, since there is a channel between the first drive wheel and the guide wheel through which the second traction member passes perpendicular to the central axis, only one guide wheel is needed to provide good guidance for the second traction member without causing the second traction member to detach from the second guide wheel. Reducing the number of guide wheels can reduce friction and energy loss.

[0029] Fourth, since the axis of the guide wheel is parallel to the axis of the central shaft, while the axis of the main shaft is perpendicular to the axis of the central shaft, the axis of the guide wheel is parallel to the axis of the main shaft. Therefore, when the second traction component extends to the surface of the guide wheel through the transmission wheel on the main shaft, it needs to turn in two directions, and the two directions are perpendicular. The chain has a strong load-bearing capacity, and due to the characteristics of the chain, it is easy to turn in the vertical direction without affecting its service life. Therefore, using the chain as the second traction component can increase the service life of the second traction component. Attached Figure Description

[0050] In the description of this application, if there are terms such as "A is connected to B in a rotatable manner", it means that A and B are directly or indirectly connected, and A is able to rotate relative to B.

[0051] In the description of this application, references to "one embodiment" or "some embodiments" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0052] like Figures 1 to 5 As shown, this embodiment discloses a cantilever structure, including a support member 200, a rotating shaft 300, and a cantilever beam 400. The rotating shaft 300 includes a central shaft and a movable outer cylinder 301. The central shaft is connected to the support member 200, and the movable outer cylinder 301 is sleeved on the central shaft. The movable outer cylinder 301 can rotate around the axis of the central shaft. One end of the cantilever beam 400 is connected to the movable outer cylinder 301.

[0053] It also includes an energy storage and assist component 100, which includes:

[0054] The elastic element 4 includes a fixed end and a movable end. The fixed end is connected to the support element 200, and the movable end is movable relative to the fixed end along the axial direction of the central axis.

[0055] The traction component includes a first traction component 31 and a second traction component 32, with one end of the first traction component 31 connected to the movable end;

[0056] The transmission unit 2 includes a main shaft 21, a first cam 22, and a first transmission wheel 23. The main shaft 21 is rotatably connected to the base 11. The first cam 22 and the first transmission wheel 23 are connected to the main shaft 21 along the axis of the main shaft 21. The axis of the main shaft 21 is perpendicular to the axis of the central shaft. The other end of the first traction member 31 extends along the surface of the first cam 22 and the extended end is connected to the first cam 22. One end of the second traction member 32 extends along the surface of the first transmission wheel 23 and the extended end is connected to the first transmission wheel 23.

[0057] The second drive wheel 7 is connected to the movable outer cylinder 301 along the axis of the movable outer cylinder 301, and the other end of the second traction member 32 extends along the surface of the second drive wheel 7, with the extended end connected to the second drive wheel 7.

[0058] The guide structure 6 includes a guide wheel 61 and an adjustment part 62. The guide wheel 61 is connected to the support member 200 and is used to guide the direction of the second traction member 32. The adjustment part 62 is used to adjust the distance between the guide wheel 61 and the main shaft 21.

[0059] It should be noted that the point of force application of the first elastic element 4 to the first cam 22 is the position where the first traction element 31 is tangent to the first cam 22. As the first traction element 31 rotates, the point of force application of the first elastic element 4 to the first cam 22 moves along the contour line of the first cam 22. When the deformation of the first elastic element 4 is at its minimum, the distance from the point of force application of the first elastic element 4 to the axis of the main shaft 21 is at its farthest. As the deformation of the first elastic element 4 increases, the distance from the point of force application of the first elastic element 4 to the axis of the main shaft 21 gradually decreases, causing the elastic force fed back to the main shaft 21 by the first elastic element 4 to show a change of first rising and then falling. Therefore, under the action of the first cam 22, the deformation of the first elastic element 4 and the force fed back to the main shaft 21 show a change state similar to the change state of the force used to resist the gravitational torque of the cantilever beam 400, which is first rising and then falling, with a peak value.

[0060] By setting an adjustment part 62 between the main shaft 21 and the second transmission wheel 7, the adjustment part 62 is used to adjust the distance between the guide wheel 61 and the main shaft 21. During the adjustment of the distance between the guide wheel 61 and the main shaft 21, under the action of the second traction member 32, the transmission part 2 can be driven to rotate accordingly. As a result, the deformation state of the elastic member 4 is changed by the first traction member 31, thereby adjusting the peak position of the elastic force fed back to the main shaft 21 by the first elastic member 4, so that it is more matched with the state of the cantilever beam 400. Thus, the peak position of the power used to resist the gravitational torque of the cantilever beam 400 is consistent with the peak position of the elastic force fed back to the main shaft 21 by the first elastic member 4, so that the curves of the two further overlap. Through the energy storage assist component 100, the energy generated by the gravitational potential energy of the downward rotation of the cantilever beam 400 can be more fully recovered and stored, and used to assist the upward rotation of the cantilever beam 400.

[0061] It should be noted that in this embodiment, the support member 200 is used to support the cantilever structure, and the base 11 is used to support the energy storage and assist component 100. The energy storage and assist component 100 is connected to the support member 200 through the base 11. The base 11 can be directly welded to the support member 200, or it can be connected to the support member 200 through a fixing structure (such as bolts, clamps, or flanges). As long as the functions of the base 11 and the support member 200 are satisfied, changes in the shape and structure of the base 11 and the support member 200 do not constitute a limitation on this embodiment.

[0062] It should be noted that, in this embodiment, the rotating shaft 300 is used to provide a stable rotation shaft 300 for the cantilever beam 400, enabling the cantilever beam 400 to rotate stably around the shaft. When an external power source is required to drive the cantilever beam 400 to move, a drive motor can be used as the power source, with the output end of the power source connected to the central shaft, thereby driving the cantilever beam 400 connected to the movable outer cylinder 301 to rotate around the central shaft.

[0063] It should be noted that, in this embodiment, the elastic element 4 stores energy through material deformation under external force, and releases the stored energy during the process of the deformation recovering or decreasing, and has the property of returning to its shape before the external force was applied. The elastic element 4 can be a tension spring, compression spring, coil spring, torsion spring, or rubber, or a combination of two or more of these. The selection of different materials or shapes of the elastic element 4 does not constitute a limitation on this embodiment, provided that the function of the elastic element 4 is satisfied.

[0064] It should be noted that, in this embodiment, in order to transmit the force of the main shaft 21 to the second transmission wheel 7 through the second traction member 32, a guide wheel 61 is provided on the base 11 to guide the direction of the second traction member 32. In order to simplify the structure of the energy storage and assist component 100 and improve the transmission efficiency, one side of the surface of the first transmission wheel 23 and one side of the surface of the guide wheel 61 form a channel through which the second traction member 32 passes in an axial direction perpendicular to the central axis. The second traction member 32 extends along this channel between the first transmission wheel 23 and the guide wheel 61. Therefore, only one guide wheel 61 is needed to achieve the guiding function, and at the same time, it can prevent the second traction member 32 from detaching from the surface of the first transmission wheel 23 or the guide wheel 61. This simplifies the guiding structure and avoids increasing the friction between the second traction member 32 and the guiding structure by setting multiple guide wheels 61, thereby reducing energy loss.

[0065] Furthermore, in this embodiment, to prevent the guide wheel 61 from deviating from the channel, the adjustment unit 62 drives the guide wheel 61 to move along the length direction of the channel.

[0066] It should be noted that in this embodiment, the traction component includes a first traction component 31 and a second traction component 32. The first traction component 31 is used to convert the rotational motion of the transmission unit 2 into linear displacement, thereby causing a change in the deformation of the elastic component 4. The second traction component 32 is used to transmit the force of the elastic component 4 to the movable outer cylinder 301 through the transmission unit 2. At the same time, the traction component, through its cooperation with the transmission unit 2, adjusts the magnitude of the force output through the main shaft 21 to adapt to different external loads. Changes in the structure or material of the traction component, while satisfying its function, do not constitute a limitation on this embodiment.

[0067] Furthermore, in this embodiment, since the axis of the guide wheel 61 is parallel to the axis of the central shaft, and the axis of the main shaft 21 is perpendicular to the axis of the central shaft, the axis of the guide wheel 61 is parallel to the axis of the main shaft 21. Therefore, when the second traction member 32 extends to the surface of the guide wheel 61 through the transmission wheel on the main shaft 21, it needs to turn in two directions, and the two directions are perpendicular. In order to avoid the second traction member 32 breaking due to excessive internal stress concentration caused by excessive torsion angle during the turning process, the second traction member 32 adopts a chain, especially a lifting chain. The lifting chain has a strong load-bearing capacity, and due to its structural characteristics, it is easy to turn in the vertical direction, thereby increasing the service life of the second traction member 32.

[0068] It should be noted that, in this embodiment, the adjustment part 62 is used to adjust the distance between the guide wheel 61 and the main shaft 21. While satisfying the function of the adjustment part 62, the implementation of the adjustment part 62 can be, but is not limited to, the following: Figures 3 to 5 As shown, the adjustment part 62 includes a strip groove 621, an adjustment block 622 and an adjustment bolt 623. The strip groove 621 is provided on the support member 200. The adjustment block 622 is provided in the strip groove 621 and is connected to the guide wheel 61. The adjustment bolt 623 is threadedly connected to the adjustment block 622.

[0069] It should be noted that when the position of the guide wheel 61 needs to be adjusted, the adjusting screw is rotated. Since the adjusting screw and the adjusting block 622 are connected by a thread, the adjusting block 622 drives the guide wheel 61 to move in the strip groove 621, thereby adjusting the deformation state of the elastic element 4.

[0070] Furthermore, in this embodiment, to increase the stability of the guide wheel 61, a U-shaped reserved groove is provided on the support member 200, and the guide wheel 61 is placed in the reserved groove, so that both sides of the guide wheel 61 are connected to the two side walls of the reserved groove, thereby increasing the stability of the guide wheel 61. The connection method between the guide wheel 61 and the reserved groove of the support member 200 includes, but is not limited to, the following:

[0071] First implementation method: such as Figure 4 and Figure 5 As shown, both sides of the reserved groove are provided with strip-shaped grooves 621, and both sides of the guide wheel 61 are provided with adjusting blocks 622. At the same time, the position of the guide wheel 61 is adjusted by adjusting the adjusting bolts 623 on both sides.

[0072] In the second implementation, one side of the reserved groove is provided with the strip groove 621, and the guide wheel 61 is provided with an adjustment block 622 on one side and a slider that is slidably connected to the strip groove 621 on the other side. The position of the guide wheel 61 can be adjusted by adjusting the adjustment bolt 623 on one side only.

[0073] It should be noted that, in this embodiment, to increase the accuracy and stability of the extension of the second traction member 32 between the guide wheel 61 and the second transmission wheel 7, such as... Figure 1 As shown, the axis of the guide wheel 61 is parallel to the axis of the central axis. Simultaneously, along the axis of the central axis, the guide wheel 61 corresponds to the position of the second transmission wheel 7, such that the groove on the surface of the guide wheel 61 and the groove on the surface of the second transmission wheel 7 are on the same plane. This allows the second traction member 32 to be stably embedded in the grooves on the surfaces of the guide wheel 61 and the second transmission wheel 7, preventing the second traction member 32 from detaching from the surfaces of the guide wheel 61 and the second transmission wheel 7, and also preventing the second traction member 32 from rubbing against the sidewalls of the grooves on the surfaces of the guide wheel 61 and the second transmission wheel 7, thereby reducing friction and increasing energy transfer efficiency.

[0074] It should be noted that, in this embodiment, in order to increase the service life of the energy storage assist component 100, such as... Figures 1 to 3 As shown, the housing 1 also includes a first protective shell 12, which is sleeved on the elastic member 4 and connected to the base 11. The first protective shell 12 and the second protective shell mechanically seal the elastic member 4, isolate it from the external environment, and increase its service life. It can also prevent the first traction member 31 or the elastic member 4 from popping out, thereby avoiding damage to the outside world.

[0075] The second aspect of this embodiment discloses a photovoltaic tracking device, including the energy storage booster component 100 as described above.

[0076] The advantages of this embodiment are: it increases the stability of the cantilever structure, increases the working efficiency of the energy storage and assist component 100, makes the structure of the energy storage and assist component 100 simpler and more efficient, and the adjustment part 62 adjusts the distance between the guide wheel 61 and the main shaft 21 in a simple and convenient way.

[0077] First, in this embodiment, the energy storage assist component 100, under the action of the first cam 22, exhibits a change in the relationship between the deformation of the first elastic element 4 and the force fed back to the main shaft 21, similar to the change in the rotational position of the cantilever beam 400 and the change in the force used to resist the gravitational torque of the cantilever beam 400. Both show an initial rise followed by a fall, with a peak value. By providing an adjustment part 62 between the main shaft 21 and the second transmission wheel 7, the adjustment part 62 is used to adjust the distance between the guide wheel 61 and the main shaft 21. During the adjustment of the distance between the guide wheel 61 and the main shaft 21, under the action of the second traction member 32, the transmission part 2 can be driven to rotate accordingly. This causes the deformation state of the elastic element 4 to change through the first traction element 31, thereby adjusting the peak position of the elastic force fed back to the main shaft 21 by the first elastic element 4, making it more compatible with the state of the cantilever beam 400. This ensures that the peak position of the force used to resist the gravitational torque of the cantilever beam 400 is consistent with the peak position of the elastic force fed back to the main shaft 21 by the first elastic element 4, making their curves further overlap. The energy storage and assist component 100 can more fully recover and store the energy generated by the gravitational potential energy when the cantilever beam 400 rotates downwards, and use it to assist the cantilever beam 400 to rotate upwards, further increasing the working efficiency of the energy storage and assist component 100.

[0078] Second, when adjusting the distance between the guide wheel 61 and the main shaft 21 through the adjustment part 62, the adjustment screw is rotated. Since the adjustment screw and the adjustment block 622 form a threaded connection, the guide wheel 61 is driven to move in the strip groove 621 through the adjustment block 622, thereby adjusting the deformation state of the elastic element 4. The adjustment method is simple and convenient.

[0079] Third, since there is a channel between the first transmission wheel 23 and the guide wheel 61 through which the second traction member 32 passes perpendicular to the central axis, only one guide wheel 61 is needed to provide good guidance for the second traction member 32 without causing the second traction member 32 to detach from the second guide wheel 61. Reducing the number of guide wheels 61 can reduce friction and energy loss.

[0080] Fourth, since the axis of the guide wheel 61 is parallel to the axis of the central shaft, while the axis of the main shaft 21 is perpendicular to the axis of the central shaft, the axis of the guide wheel 61 is parallel to the axis of the main shaft 21. Therefore, when the second traction member 32 extends to the surface of the guide wheel 61 through the transmission wheel on the main shaft 21, it needs to turn in the vertical direction. The chain has a strong load-bearing capacity, and due to the characteristics of the chain, it is easy to turn in the vertical direction without affecting its service life. Therefore, using the chain as the second traction member 32 can increase the service life of the second traction member 32.
