Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic technology, and more specifically, to a support structure and a photovoltaic module. Background Technology
[0002] Currently, portable photovoltaic (PV) modules are typically supported on the ground by a support assembly. When the support assembly is deployed, a triangular structure is formed between the support assembly, the ground, and the PV device (such as a PV panel), allowing the PV device to stand at an angle. However, the tilt angle of the PV device in existing PV modules is usually fixed and difficult to adjust. Furthermore, to achieve angle adjustment, complex adjustment mechanisms are often added, resulting in poor reliability.
[0003] In view of the above, this application is hereby submitted. Utility Model Content
[0004] The purpose of this application is to provide a support structure and a photovoltaic module that can easily adjust the tilt angle of the photovoltaic device and has a simple and reliable structure.
[0005] The embodiments of this application can be implemented as follows: In a first aspect, this application provides a support mechanism for supporting photovoltaic devices. The support mechanism includes a support component, a pull rope, and a retractable structure. The support component has a connecting end and a supporting end. The connecting end is used to rotatably connect to the photovoltaic device, and the supporting end is used to support the ground. The pull rope has a fixed end and a movable end. The fixed end is connected to the photovoltaic device. The support component is provided with a mating structure. The pull rope is slidably mated with the mating structure. The movable end of the pull rope is connected to the retractable structure. A section of the pull rope extending from the fixed end to the mating structure is defined as an effective rope segment. A section of the pull rope extending from the mating structure to the movable end is defined as a redundant rope segment. The retractable structure is connected to the effective rope segment and can adjust its position along the effective rope segment.
[0006] In an optional embodiment, the retracting structure is provided with an adjustment hole, and the effective rope segment of the pull rope passes through the adjustment hole. When the effective rope segment is taut, there is damping between the retracting structure and the effective rope segment that can prevent the effective rope segment from sliding along the adjustment hole.
[0007] In an optional implementation, the take-up and release structure is provided with at least two adjustment holes, which are through holes, and the effective rope segments pass through each adjustment hole in sequence.
[0008] In an optional embodiment, the retractable structure is provided with a connecting hole, which is a through hole, and the movable end of the pull rope is connected to the retractable structure through the connecting hole.
[0009] In an optional embodiment, the movable end of the pull rope passes through the connecting hole, and the movable end is connected to a limiting part. The diameter of the connecting hole is smaller than the size of the limiting part so that the limiting part cannot pass through the connecting hole.
[0010] In an optional embodiment, the retractable structure is provided with a first adjustment hole, a second adjustment hole, and a connecting hole. The first adjustment hole, the second adjustment hole, and the connecting hole are all through holes. The first adjustment hole, the second adjustment hole, and the connecting hole are arranged sequentially in a straight line. The effective rope segment passes through the first adjustment hole and the second adjustment hole in sequence. The movable end of the pull rope is connected to the retractable structure through the connecting hole.
[0011] In an optional implementation, the retraction structure is a sheet material with an integrated structure.
[0012] In an optional embodiment, the mating structure includes a threading hole formed in the support component, through which a pull rope is threaded.
[0013] In an optional embodiment, the support assembly includes a support rod and a support base. The support base is used to connect the photovoltaic device. One end of the support rod is rotatably connected to the support base, and the other end forms the support end of the support assembly and is used to support the ground.
[0014] Secondly, this application provides a photovoltaic module, including photovoltaic devices and a support structure according to any of the foregoing embodiments.
[0015] The beneficial effects of the support structure and photovoltaic module provided in this application embodiment include: The support mechanism provided in this application is used to support photovoltaic devices. The support mechanism includes a support component, a pull rope, and a retraction structure. The support component has a connecting end and a supporting end. The connecting end is rotatably connected to the photovoltaic device, and the supporting end is supported on the ground. The pull rope has a fixed end and a movable end. The fixed end is connected to the photovoltaic device. A mating structure is provided on the support component, and the pull rope slides into the mating structure. The movable end of the pull rope is connected to the retraction structure. A section of the pull rope extending from the fixed end to the mating structure is defined as an effective rope segment, and a section extending from the mating structure to the movable end is defined as a redundant rope segment. The retraction structure is connected to the effective rope segment and can adjust its position along the effective rope segment. In use, the fixed end of the pull rope is connected to the lower end of the photovoltaic device, and the connecting end of the support component is connected to the upper end of the photovoltaic device. The lower end of the photovoltaic device can support the ground. The support component, the photovoltaic device, and the pull rope form a stable triangular structure. The angle between the support component and the photovoltaic device is determined by the length of the effective rope segment of the pull rope. Therefore, adjusting the length of the effective rope segment can adjust the tilt angle of the photovoltaic device. When it is necessary to reduce the angle between the photovoltaic device and the support assembly, simply adjust the position of the retractable structure towards the fixed end of the pull rope. This increases the redundant rope segment, and correspondingly shortens the effective rope segment. Conversely, when it is necessary to increase the angle between the photovoltaic device and the support assembly, simply adjust the position of the retractable structure towards the direction of the mating structure on the support assembly. This shortens the redundant rope segment, and correspondingly increases the effective rope segment. Therefore, the support mechanism provided in this embodiment can adjust the length of the effective rope segment of the pull rope, thereby adjusting the tilt angle of the photovoltaic device, simply by adjusting the position of the retractable structure. The entire structure is simple, reliable, and easy to adjust.
[0016] The photovoltaic module provided in this application includes the aforementioned support structure and photovoltaic device, which can easily adjust the tilt angle of the photovoltaic device and has a simple and reliable structure. Attached Figure Description

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0021] 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 to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0023] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0024] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0025] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0026] In existing photovoltaic (PV) modules, PV devices (such as PV panels) are supported by both brackets and the ground. The angle of the PV device relative to the ground is generally fixed, which is not conducive to adjusting the PV device to achieve its optimal working state. In order to improve the flexibility of PV module use, related technologies have added mechanisms that can adjust the tilt angle of PV devices. However, these adjustment mechanisms are often complex in structure and have problems such as inconvenience in adjustment and poor reliability.
[0027] To address at least one deficiency in the aforementioned related technologies, this application provides a support mechanism that, by incorporating a pull rope and a retraction structure, adjusts the effective rope length between the support component and the photovoltaic device, thereby adjusting the tilt angle of the photovoltaic device. This structure is simple, reliable, and easy to adjust. Furthermore, this application also provides a photovoltaic module, including a photovoltaic device and the aforementioned support mechanism.
[0028] Figure 1 This is a schematic diagram of a photovoltaic module in one embodiment of this application. Figure 1 As shown, the photovoltaic module provided in this application embodiment includes a photovoltaic device 400 and a support mechanism. The photovoltaic device 400 includes a photovoltaic panel; further, the photovoltaic device 400 may also include other components such as a frame and a back panel. The support mechanism connects the photovoltaic device 400, and both the photovoltaic device 400 and the support mechanism are supported on the ground. The light-receiving surface of the photovoltaic device 400 can maintain a certain tilt angle with the ground. In this application embodiment, the support mechanism includes a support component 100, a pull rope 200, and a retraction structure 300. The support component 100 has a connecting end and a supporting end. The connecting end is used to rotatably connect with the photovoltaic device 400, and the supporting end is used to support the ground. Specifically, the photovoltaic device 400 is plate-shaped, with its upper end connected to the connecting end of the support component 100 and its lower end supporting the ground. The pull rope 200 is connected between the support components 100 to provide tension to prevent the supporting end of the support component 100 from separating excessively from the lower end of the photovoltaic device 400. That is, the pull rope 200 is used to constrain the opening angle between the photovoltaic device 400 and the support component 100. Therefore, the pull rope 200, the support component 100, and the photovoltaic device 400 can form a stable triangular structure.
[0029] In this embodiment, the support assembly 100 includes a support rod 110 and a base 120. The base 120 is connected to the photovoltaic device 400 (specifically, to the backlight surface of the photovoltaic device 400). One end of the support rod 110 is rotatably connected to the base 120, and the other end forms the support end of the support assembly 100 and is used to support the ground. Optionally, the base 120 is provided with a pivot, and the end of the support rod 110 is provided with a shaft hole. The pivot and the shaft hole cooperate to realize the rotatable connection between the base 120 and the support rod 110; or, the base 120 is provided with a shaft hole, and the end of the support rod 110 is provided with a pivot, which can also realize the rotatable connection between the base 120 and the support rod 110. In other embodiments, the rotatable connection between the support assembly 100 and the photovoltaic device 400 can also be realized by a structure such as a hinge.
[0030] Figure 2 This is a partial schematic diagram of the support mechanism in one embodiment of this application. (In conjunction with...) Figure 1 and Figure 2 As shown in this embodiment, the pull rope 200 has a fixed end 201 and a movable end 202, with the fixed end 201 connected to the photovoltaic device 400. A mating structure 111 is provided on the support assembly 100, and the pull rope 200 slides in conjunction with the mating structure 111. The movable end 202 of the pull rope 200 is connected to the retraction structure 300. A section of the pull rope 200 extending from the fixed end 201 to the mating structure 111 is defined as an effective rope segment 210, and one end of the pull rope 200 extending from the mating structure 111 to the movable end 202 is defined as a redundant rope segment 220. The retraction structure 300 is connected to the effective rope segment 210 and can adjust its position along the effective rope segment 210. Specifically, in this embodiment, the mating structure 111 is provided on the support rod 110 and close to the support end. It can be understood that the length of the effective rope segment 210 determines the angle between the support rod 110 and the photovoltaic device 400, that is, the tilt angle between the photovoltaic device 400 and the ground. When the retraction structure 300, carrying the movable end 202 of the pull rope 200, adjusts its position on the effective rope segment 210, the distance between the movable end 202 of the pull rope 200 and the mating structure 111 on the support rod 110 changes. That is, the lengths of both the redundant rope segment 220 and the effective rope segment 210 change. When the retraction structure 300 moves towards the fixed end 201 of the pull rope 200, the redundant rope segment 220 becomes longer, the effective rope segment 210 becomes shorter, the angle between the support rod 110 and the photovoltaic device 400 decreases, and the angle between the light-receiving surface of the photovoltaic device 400 and the ground increases. When the retraction structure 300 moves towards the mating structure 111, the redundant rope segment 220 becomes shorter, the effective rope segment 210 becomes longer, the angle between the support rod 110 and the photovoltaic device 400 increases, and the angle between the light-receiving surface of the photovoltaic device 400 and the ground decreases.
[0031] As can be seen, the support mechanism provided in this application embodiment can achieve the tilt angle adjustment of the photovoltaic device 400 by simply adjusting the position of the retractable structure 300.
[0032] Figure 3 This is a schematic diagram illustrating the interaction between the retractable structure 300 and the pull rope 200 in one embodiment of this application. (In conjunction with...) Figures 1 to 3 As shown, the retractable structure 300 is provided with an adjustment hole, and the effective rope segment 210 of the pull rope 200 passes through the adjustment hole. When the effective rope segment 210 is taut, there is damping between the retractable structure 300 and the effective rope segment 210, which can prevent the effective rope segment 210 from sliding along the adjustment hole. In this embodiment, the retractable structure 300 is a sheet material with an integral structure. The effective rope segment 210 of the pull rope 200 passes through the adjustment hole. When the pull rope 200 is taut, the effective rope segment 210 will bend at the adjustment hole, and there is a large static friction force between it and the retractable structure 300 (i.e., damping that can overcome the sliding of the retractable structure 300 on the effective rope segment 210). Therefore, when the pull rope 200 is taut, the retractable structure 300 will not slide on the effective rope segment 210, thereby keeping the length of the effective rope segment 210 fixed and the tilt angle of the photovoltaic device 400 fixed. When it is necessary to adjust the take-up and release structure 300, keep the pull rope 200 slack to reduce the damping between the effective rope segment 210 and the take-up and release structure 300, and then adjust the position of the take-up and release structure 300 along the effective rope segment 210.
[0033] Optionally, the retractable structure 300 is provided with at least two adjustment holes, which are through holes through which the effective rope segment 210 passes sequentially. By using multiple adjustment holes, the damping between the retractable structure 300 and the pull rope 200 can be increased, preventing the retractable structure 300 from sliding on the pull rope 200 (specifically, the effective rope segment 210) when the pull rope 200 is taut. In this embodiment, the retractable structure 300 is provided with two adjustment holes, namely a first adjustment hole 310 and a second adjustment hole 320. The retractable structure 300 is also provided with a connecting hole 330, which is a through hole through which the movable end 202 of the pull rope 200 is connected to the retractable structure 300. The first adjustment hole 310, the second adjustment hole 320, and the connecting hole 330 are arranged sequentially in a straight line, and the effective rope segment 210 passes sequentially through the first adjustment hole 310 and the second adjustment hole 320.
[0034] In this embodiment, the movable end 202 of the pull cord 200 passes through the connecting hole 330, and the movable end 202 is connected to the limiting part 230. The diameter of the connecting hole 330 is smaller than the size of the limiting part 230 so that the limiting part 230 cannot pass through the connecting hole 330. With this arrangement, when the pull cord 200 is taut, the movable end 202 of the pull cord 200 can be held at the retractable structure 300; when adjusting the position of the retractable structure 300, the movable end 202 of the pull cord 200 can move together with the retractable structure 300. The limiting part 230 can be a knot or other components connected to the movable end 202. In other optional embodiments, the movable end 202 of the pull cord 200 can also be tied to the retractable structure 300.
[0035] To prevent excessive wear on the inner edges of the adjustment hole and the connecting hole 330 on the pull rope 200, optionally, a chamfer transition is provided between the inner walls of the first adjustment hole 310, the second adjustment hole 320, and the connecting hole 330 and the two surfaces of the retracting structure 300.
[0036] In this embodiment, the friction between the adjustment hole and the pull rope 200 is used to prevent the retraction structure 300 from sliding along the effective rope segment 210 when the pull rope 200 is taut. In other optional embodiments, the pulling structure can be other structural forms, such as a clamp that holds the effective rope segment 210 to maintain sufficient static friction.
[0037] In this embodiment, the mating structure 111 includes a threading hole formed in the support component 100, through which the pull rope 200 passes. Specifically, the threading hole is formed in the support rod 110; the number of threading holes can be one or two, and after the pull rope 200 passes through and slides, a sliding engagement is formed with the support rod 110. In other optional embodiments, the mating structure 111 can also be other structural forms, as long as it can achieve a sliding engagement with a specific position of the support component 100; for example, the mating structure 111 can also be a fixed pulley installed on the support rod 110.
[0038] In summary, this application provides a support mechanism. The support mechanism includes a support component 100, a pull rope 200, and a retractable structure 300. The support component 100 has a connecting end and a supporting end. The connecting end is used to rotatably connect to a photovoltaic device 400, and the supporting end is used to support the ground. The pull rope 200 has a fixed end 201 and a movable end 202. The fixed end 201 is connected to the photovoltaic device 400. A mating structure 111 is provided on the support component 100. The pull rope 200 slides in conjunction with the mating structure 111. The movable end 202 of the pull rope 200 is connected to the retractable structure 300. A section of the pull rope 200 extending from the fixed end 201 to the mating structure 111 is defined as an effective rope segment 210, and a section of the pull rope 200 extending from the mating structure 111 to the movable end 202 is defined as a redundant rope segment 220. The retractable structure 300 is connected to the effective rope segment 210 and can adjust its position along the effective rope segment 210. In use, the fixed end 201 of the pull rope 200 is connected to the lower end of the photovoltaic device 400, and the connecting end of the support component 100 is connected to the upper end of the photovoltaic device. The lower end of the photovoltaic device 400 can support the ground. The support component 100, the photovoltaic device 400, and the pull rope 200 form a stable triangular structure. The angle between the support component 100 and the photovoltaic device 400 is determined by the length of the effective rope segment 210 of the pull rope 200. Therefore, adjusting the length of the effective rope segment 210 can adjust the tilt angle of the photovoltaic device 400. When it is necessary to reduce the angle between the photovoltaic device 400 and the support component 100, simply adjust the position of the retractable structure 300 towards the fixed end 201 of the pull rope 200. This increases the length of the redundant rope segment 220 and correspondingly shortens the effective rope segment 210. Conversely, when it is necessary to increase the angle between the photovoltaic device 400 and the support component 100, simply adjust the position of the retractable structure 300 towards the direction of the mating structure 111 on the support component 100. This shortens the redundant rope segment 220 and correspondingly increases the length of the effective rope segment 210. Therefore, the support mechanism provided in this embodiment can adjust the length of the effective rope segment 210 of the pull rope 200 by simply adjusting the position of the retractable structure 300, thereby adjusting the tilt angle of the photovoltaic device 400. The entire structure is simple, reliable, and easy to adjust.
[0039] This application also provides a photovoltaic module, including the aforementioned support structure and photovoltaic device 400, which can conveniently adjust the tilt angle of the photovoltaic device 400 and has a simple and reliable structure.
[0040] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
