DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0021] Embodiments of the present application provide a photovoltaic panel angle adjustment device, a photovoltaic device, and a photovoltaic system.

[0022] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0023] Please refer to Figure 1 , Figure 1 A schematic structural diagram of an angle adjustment device for a photovoltaic panel provided in one embodiment of the present application.

[0024] like Figure 1As shown, the angle adjustment device of the photovoltaic panel provided in the embodiment of the present application includes: a support mechanism 10, the support mechanism 10 is provided with a first hinge part 11, a second hinge part 12 and a third hinge part 13, and the first hinge part 11, the second hinge part 12 and the third hinge part 13 are arranged at intervals and arranged in a triangular shape on a side of the support mechanism 10 close to the angle adjustment mechanism 20; the angle adjustment mechanism 20, the angle adjustment mechanism 20 includes a first telescopic component 21 hinged to the first hinge part 11, a second telescopic component 22 hinged to the second hinge part 12 and a third telescopic component 23 hinged to the third hinge part 13, wherein the telescopic lengths of the first telescopic component 21, the second telescopic component 22 and the third telescopic component 23 are all adjustable, and the angle between the support mechanism 10 and the horizontal direction can be changed by adjusting the telescopic length of any one of the first telescopic component 21, the second telescopic component 22 and the third telescopic component 23.

[0025] It is understandable that the incident angle of sunlight changes with time, and there are differences at different times of the day or at the same time in different seasons. In order to improve the power generation efficiency of photovoltaic panels using sunlight, it is necessary to make the sunlight enter the photovoltaic panels as vertically as possible. Therefore, in order to adapt to the change of the incident angle of sunlight, an embodiment of the present application provides an angle adjustment device for photovoltaic panels.

[0026] Specifically, the photovoltaic panel is arranged on the support mechanism 10, and the support mechanism 10 is respectively hinged with the first telescopic component 21, the second telescopic component 22, and the third telescopic component 23 of the angle adjustment mechanism 20 through the first hinge part 11, the second hinge part 12, and the third hinge part 13. Among them, the first hinge part 11, the second hinge part 12, and the third hinge part 13 are arranged in a triangular shape on the side of the support mechanism 10 close to the angle adjustment mechanism 20, so that the support points where the first telescopic component 21, the second telescopic component 22, and the third telescopic component 23 are hinged with the support mechanism 10 form a triangle, which can support the support mechanism 10 more stably.

[0027] Please refer to Figure 2 , Figure 2 A schematic structural diagram of an angle adjustment device for a photovoltaic panel provided in another embodiment of the present application.

[0028] like Figure 2 As shown, by adjusting the telescopic lengths of the first telescopic assembly 21, the second telescopic assembly 22, and the third telescopic assembly 23, the angle between the support mechanism 10 and the horizontal direction can be adjusted. It can be understood that the arrangement of the first hinge 11, the second hinge 12, and the third hinge 13 is only an example, and the actual arrangement of the first hinge 11, the second hinge 12, and the third hinge 13 is not limited to Figure 1 , Figure 2Specifically, the first hinge part 11, the second hinge part 12, and the third hinge part 13 can be arranged in an isosceles triangle or an equilateral triangle on the back of the support mechanism 10, or can be arranged in a triangle of any shape, which is not limited here.

[0029] For example, when the height of the first telescopic component 21 and the second telescopic component 22 is greater than the third telescopic component 23, if it is necessary to reduce the angle between the support mechanism 10 and the horizontal direction, the angle between the support mechanism 10 and the horizontal direction can be reduced by stretching the first telescopic component 21, stretching the telescopic length of the second telescopic component 22, or compressing the telescopic length of the third telescopic component 23; conversely, if it is necessary to increase the angle between the support mechanism 10 and the horizontal direction, the angle between the support mechanism 10 and the horizontal direction can be increased by compressing the first telescopic component 21, compressing the telescopic length of the second telescopic component 22, or stretching the telescopic length of the third telescopic component 23. Of course, it is not limited to this and is not limited here.

[0030] Please refer to Figure 3 , Figure 3 A schematic structural diagram of an angle adjustment device for a photovoltaic panel provided in another embodiment of the present application.

[0031] like Figure 3 As shown, in some embodiments, the support mechanism 10 includes a support component 101 and a locking component 102, wherein the support component 101 is provided with a placement position for placing the photovoltaic panel, the locking component 102 is connected to the support component 101, and the locking component 102 has a locked state and an unlocked state; when the locking component 102 is in the locked state, the locking component 102 is locked and matched with the photovoltaic panel placed in the placement position to fix the photovoltaic panel to the placement position of the support mechanism 10; when the locking component 102 is triggered by an external force, the locked state can be switched to the unlocked state to release the locking cooperation with the photovoltaic panel.

[0032] Exemplarily, the number of locking components 102 may be one or more, and one or more locking components 102 may be respectively disposed on at least one edge of the support component 101 to limit the photovoltaic panel in the position of the support component 101 from at least one direction.

[0033] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of a support mechanism provided by an embodiment of the present application.

[0034] like Figure 4As shown, the locking assembly 102 includes a connecting portion 1021, a locking tongue portion 1022, an elastic portion 1023 and a force-applying portion 1024; wherein the connecting portion 1021 is connected to the supporting assembly 101, and the locking tongue portion 1022 is installed on the connecting portion 1021 and can move relative to the connecting portion 1021; the elastic portion 1023 is extended along the direction of the locking tongue portion 1022 to provide elastic force for the locking tongue portion 1022; the force-applying portion 1024 is at least partially exposed to the connecting portion 1021 and can move relative to the connecting portion 1021. The connecting portion 1021 is displaced; when the force-applying portion 1024 is triggered by an external force, the force-applying portion 1024 pushes the locking tongue portion 1022 to move in a first direction to release the locking cooperation between the support assembly 101 and the photovoltaic panel, and causes the elastic portion 1023 to deform and store energy; when the external force that triggers the force-applying portion 1024 is released, under the action of the elastic force of the elastic portion 1023, the locking tongue portion 1022 moves in a second direction opposite to the first direction to lock the photovoltaic panel in the placement position.

[0035] Exemplarily, by applying external force to the force-applying portion 1024, the locking assembly 102 is triggered to switch from the locked state to the unlocked state, that is, the force-applying portion 1024 is triggered to push the locking tongue portion 1022 to move toward the side close to the connecting portion 1021 to release the locking cooperation between the photovoltaic panel and the supporting assembly 101. When the locking assembly 102 is in the unlocked state, the locking tongue portion 1022 of the locking assembly 102 is retracted into the connecting portion 1021, so that the user can take out the photovoltaic panel in the placement position.

[0036] Similarly, when the external force of the trigger force applying part 1024 is released, the trigger locking assembly 102 switches from the unlocked state to the locked state, and under the elastic force of the elastic part 1023, the lock tongue part 1022 moves to the side away from the connecting part 1021. When the locking assembly 102 is in the locked state, the lock tongue part 1022 of the locking assembly 102 partially blocks the opening of the placement position of the support assembly 101, so that the photovoltaic panel can be locked in the placement position, so that the photovoltaic panel cannot enter or leave the placement position through the opening.

[0037] Please refer to Figure 5 , Figure 5 A schematic structural diagram of an angle adjustment device for a photovoltaic panel provided in another embodiment of the present application.

[0038] like Figure 5 As shown, the angle adjustment device of the photovoltaic panel also includes a weight-bearing mechanism 30, which includes a first weight-bearing component fixedly connected to the first telescopic component 21, a second weight-bearing component fixedly connected to the second telescopic component 22, and a third weight-bearing component fixedly connected to the third telescopic component 23.

[0039] For example, the first load-bearing component, the second load-bearing component, and the third load-bearing component of the load-bearing mechanism 30 may be made of a material with a relatively high density, such as concrete or alloy, but are not limited thereto. By respectively fixing the first telescopic component 21 to the first load-bearing component, the second telescopic component 22 to the second load-bearing component, and the third telescopic component 23 to the third load-bearing component, the photovoltaic panel is prevented from tipping over or overturning, thereby improving the stability of the angle adjustment device.

[0040] In some embodiments, the weight-bearing mechanism 30 also includes a first embedded bolt fixedly arranged on the first weight-bearing component, a second embedded bolt fixedly arranged on the second weight-bearing component, and a third embedded bolt fixedly arranged on the third weight-bearing component. The first telescopic component 21, the second telescopic component 22, and the third telescopic component 23 are respectively fixedly connected to the first weight-bearing component, the second weight-bearing component, and the third weight-bearing component through the first embedded bolt, the second embedded bolt, and the third embedded bolt, respectively.

[0041] Exemplarily, the first load-bearing component, the second load-bearing component, and the third load-bearing component of the load-bearing mechanism 30 are respectively provided with embedded bolts, and the first telescopic component 21, the second telescopic component 22, and the third telescopic component 23 are respectively fixed to the load-bearing mechanism 30 by the embedded bolts to increase the firmness of the device.

[0042] In some embodiments, at least one of the first telescopic assembly 21 , the second telescopic assembly 22 , and the third telescopic assembly 23 is an electric telescopic rod, and the photovoltaic panel is electrically connected to the electric telescopic rod.

[0043] Exemplarily, the first telescopic assembly 21, the second telescopic assembly 22 and the third telescopic assembly 23 may be electric telescopic rods, and the electric telescopic rods are powered by photovoltaic panels to automatically adjust the angle between the support mechanism 10 and the horizontal direction.

[0044] Exemplarily, the correspondence between the date, time and angle can be pre-set in the controller so as to adjust the angle of the support mechanism 10 according to the solar angle corresponding to different seasons and times, and automatically adjust the angle between the support mechanism 10 and the horizontal direction to a certain angle at a certain moment. Of course, it is not limited to this, and the angle between the automatically adjustable support mechanism 10 and the horizontal direction can also be adjusted to a preset angle through a preset instruction trigger. For example, when there is snow on the surface of the photovoltaic panel, the angle between the adjustable support mechanism 10 and the horizontal direction is adjusted to close to 90° through a preset instruction, and the snow on the surface of the photovoltaic panel is removed, etc., so as to improve the adaptability of the angle adjustment device to various scenes and improve the power generation efficiency of the photovoltaic panel in snowy scenes.

[0045] In some embodiments, the angle adjustment device also includes a light sensor and a controller, wherein the light sensor is disposed on the support mechanism 10 and is used to sense light intensity, and the controller is electrically connected to the light sensor and the angle adjustment mechanism 20, and is used to control the angle adjustment mechanism 20 to adjust the angle between the support mechanism 10 and the horizontal direction.

[0046] For example, a light sensor may be provided on the surface of the support mechanism 10, and the angle between the support assembly 101 and the horizontal direction may be adjusted according to the light intensity sensed by the light sensor to determine the angle at which the light intensity is maximized. Specifically, the angle between the support assembly 101 and the horizontal direction may be increased or decreased at regular intervals, and the angle at which the light intensity is maximized may be determined by comparing the change in light intensity when the angle is increased or decreased.

[0047] Specifically, for example, if the light intensity increases when the angle between the support component 101 and the horizontal direction decreases, and when the angle is reduced to a certain angle threshold, the light intensity increases to a certain light intensity threshold, and if the angle continues to decrease beyond the angle threshold, the light intensity also decreases. Then, the angle threshold is determined as the angle between the support component 101 and the horizontal direction, so that the photovoltaic panel can receive sunlight to the greatest extent.

[0048] Please refer to Figure 6 , Figure 6 A schematic structural diagram of an angle adjustment assembly provided in one embodiment of the present application.

[0049] like Figure 6 As shown, in some embodiments, at least one of the first telescopic component 21, the second telescopic component 22, and the third telescopic component 23 is provided with a first fixed portion 201 and a second fixed portion 202; the first fixed portion 201 is provided with at least one first fixed position 2011, and the second fixed portion 202 is provided with at least one second fixed position 2021, and the first fixed position 2011 is matched with the second fixed position 2021 through a position adjustment member to adjust the telescopic length of at least one of the corresponding first telescopic component 21, the second telescopic component 22, and the third telescopic component 23.

[0050] Exemplarily, the telescopic length of at least one of the first telescopic component 21, the second telescopic component 22, and the third telescopic component 23 can also be manually adjusted, that is, at least one of the first telescopic component 21, the second telescopic component 22, and the third telescopic component 23 is a preset telescopic component, which includes a first connecting rod and a second connecting rod, wherein the first connecting rod is provided with a first fixed portion 201, and the second connecting rod is provided with a second fixed portion 202, and the telescopic length of the preset telescopic rod is adjusted by manually adjusting the matching relationship between the first fixed portion 201 and the second fixed portion 202.

[0051] Exemplarily, the first fixing part 201 is provided with at least one first fixing position 2011, and the second fixing part 202 is provided with at least one second fixing position 2021. The different first fixing parts 201 and the second fixing parts 202 are matched with each other through the position adjusting member to change the telescopic length of the preset telescopic rod. Among them, the first fixing position 2011 can be a first limiting hole, and the second fixing position 2021 can be a second limiting hole. The position adjusting member penetrates the first limiting hole and the second limiting hole of different heights to change the telescopic length of the preset telescopic rod. For example, by making the first fixing position 2011 with the lowest height on the first fixing part 201 cooperate with the second fixing position 2021 with the highest height on the second fixing part 202, the length of the preset telescopic rod is maximized. Conversely, by making the first fixing position 2011 with the highest height on the first fixing part 201 cooperate with the second fixing position 2021 with the lowest height on the second fixing part 202, the length of the preset telescopic rod is minimized.

[0052] In some embodiments, the embodiments of the present application also provide a photovoltaic device, comprising: a photovoltaic panel, and an angle adjustment device as described in any one of the embodiments of the present application, wherein the angle adjustment device is used to support the photovoltaic panel and adjust the relative angle between the photovoltaic panel and the horizontal plane.

[0053] Illustratively, the photovoltaic device provided in the embodiment of the present application includes a photovoltaic panel and an angle adjustment device for supporting the photovoltaic panel, wherein the angle adjustment device is also used to adjust the relative angle between the photovoltaic panel and the horizontal plane.

[0054] The photovoltaic panel is electrically connected to the angle adjustment device to supply power to the angle adjustment device, but this is certainly not limited to this and is not limited here.

[0055] In some implementations, the present application also provides a photovoltaic system, which includes a battery 1 and a photovoltaic device 2 as described in the present application, and the battery 1 is electrically connected to a photovoltaic panel of the photovoltaic device 2.

[0058] Exemplarily, a storage battery 1 is arranged on a side of the photovoltaic device 2 away from the photovoltaic panel. The storage battery 1 is electrically connected to the photovoltaic panel of the photovoltaic device 2 and is used to store the electrical energy generated by the photovoltaic panel of the photovoltaic device 2 .
