[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] In the present disclosure, unless otherwise stated, the directional words used, such as "upper, lower, top, and bottom", generally refer to the upper, lower, top, and bottom of the corresponding component in the direction of gravity when in use, and "inner and outer" refer to the inner and outer relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first, second", etc., are used to distinguish one element from another, and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0025] The present disclosure provides a photovoltaic assembly, comprising: a bracket 2; a photovoltaic panel 1, which is rotatably arranged on the bracket 2 to adjust the lighting angle; and a focusing element 3, which is adjustable in angle on one of the bracket 2 or the photovoltaic panel 1 to concentrate sunlight on the photovoltaic panel 1.

[0026] Through the above technical solution, the photovoltaic panel 1 can be rotatably set on the bracket 2. The angle between the photovoltaic panel 1 and the sunlight can be adjusted by rotating the photovoltaic panel 1 so that the photovoltaic panel 1 can always face the sunlight to increase the light intensity. The focusing element 3 is set on one of the bracket 2 or the photovoltaic panel 1. The sunlight is reflected on the focusing element 3. The angle of the focusing element 3 is adjusted so that the sunlight can be concentrated on the photovoltaic panel 1, thereby increasing the light intensity and enhancing the utilization rate of sunlight.

[0027] As an optional implementation, Figure 1 and Figure 4As shown, the photovoltaic assembly also includes a first driving device 5, such as a motor, and the bracket 2 includes two oppositely arranged support rods 21 and a rotating shaft 22 horizontally arranged between the two support rods 21. The center of one side of the photovoltaic panel 1 is connected to the rotating shaft 22 and the rotating shaft 22 is connected to the first driving device 5 to drive the photovoltaic panel 1 to rotate. The photovoltaic panel 1 is set on the rotating shaft 22 and rotates along the rotating shaft 22. The first driving device 5 is connected to the rotating shaft 22 to drive the photovoltaic panel 1 to rotate. The first driving device 5 can rotate forward or reverse. The maximum rotation angle of the photovoltaic panel 1 is 180°, that is, ±90° along the horizontal plane, so that the side receiving sunlight is always facing the sunlight.

[0028] Optionally, the first driving device 5 can drive the rotating shaft 22 in any suitable manner. For example, in the present disclosure, the first driving device 5 is disposed at the bottom of the bracket 2 and connected to the rotating shaft 22 through a transmission belt 6. A mounting seat can be disposed at the bottom of the bracket 2, and the first driving device 5 is disposed on the mounting seat. In other embodiments, the first driving device 5 can also be connected to the rotating shaft 22 by means of a gear set, a chain, etc.

[0029] As an optional implementation, Figure 1-2 As shown, the focusing member 3 is disposed on one or both sides of the photovoltaic panel 1 extending horizontally, that is, disposed on one or both sides of the photovoltaic panel 1 parallel to the rotating shaft 22, and does not hinder the rotation of the photovoltaic panel 1. In other embodiments, the focusing member 3 can also be disposed on the bracket 2, for example, disposed on the top of the two support rods 21 of the bracket 2.

[0030] Optionally, the photovoltaic assembly also includes a second driving device 8, and the focusing element 3 is constructed as an arc-shaped focusing plate, one end of which is rotatably connected to the photovoltaic panel 1 through the second driving device 8. The second driving device 8 can be a micro motor, on which a battery can be directly installed to avoid wire entanglement when the photovoltaic panel 1 rotates. The other end is bent toward the side of the photovoltaic panel 1 facing the sunlight, and the curved surface is a reflective surface. The sunlight is reflected onto the photovoltaic panel 1 through the curved surface, so that the sunlight is concentrated and the light intensity is increased.

[0031] As an optional implementation, Figure 1-3 As shown, the photovoltaic module also includes a cleaning device 4 for cleaning the surface of the photovoltaic panel 1. Since the photovoltaic module works in an outdoor open-air environment for a long time, the tempered glass on the surface is easily accumulated with dust and contaminated, resulting in a decrease in light transmittance, and thus a decrease in power generation efficiency. Therefore, a cleaning device 4 is provided to clean the surface of the photovoltaic panel 1.

[0032] Alternatively, if Figure 1As shown, the cleaning device 4 includes a rainwater collection box 41, a connecting pipe 42, a water pump 43 and a cleaning head 44. The top opening of the rainwater collection box 41 is used to collect rainwater. A filter screen 45 is provided at the opening to filter the rainwater. In this way, rainwater can be used to clean the photovoltaic components to save water resources. Of course, when there is no rainwater and the photovoltaic panel 1 needs to be cleaned, water can be manually injected into the rainwater collection box 41. The connecting pipe 42 is used to connect the rainwater collection box 41 and the cleaning head 44 so that the cleaning head 44 can spray water toward the side of the photovoltaic panel 1 facing the sun. The water pump 43 is arranged on the connecting pipe 42. The water in the rainwater collection box 41 is pumped out to the cleaning head 44 through the water pump 43 to clean the photovoltaic panel 1.

[0033] The cleaning head 44 is movably arranged on the photovoltaic panel 1 to increase the cleaning area and avoid a cleaning blind area.

[0034] In addition, if Figure 2-3 As shown, the photovoltaic assembly also includes a mounting plate 7 for mounting the photovoltaic panel 1 and a third driving device 9 arranged at the edge of the mounting plate 7 for driving the cleaning head 44 to move. The cleaning head 44 is constructed as a water spray pipe extending along the width direction of the photovoltaic panel 1, and the width direction is the direction extending in the same direction as the rotating shaft 22. The water spray pipe is constructed as a hard water pipe. A plurality of water spray holes 441 are provided on the side of the water spray pipe facing the photovoltaic panel 1. A first slide 72 and a rack 71 are provided on an edge of one side of the mounting plate 7 perpendicular to the water spray pipe, and a second slide 73 is provided on the other side opposite to the first slide 72. The third driving device 9 is slidably connected to the first slide 72, and a gear 91 meshing with the rack 71 is provided on the driving end of the third driving device 9. One end of the water spray pipe is connected to the third driving device 9, and the other end is provided with a roller 442 to be slidably connected with the second slide 73. The third driving device 9 can be a motor, and a gear 91 is provided at its driving end. The third driving device 9 can be moved along the first slide by meshing with the rack 71. The second end of the water spray pipe is slidably connected to the second slideway 73 through the roller 442, so that the water spray pipe can move smoothly along the length direction of the photovoltaic panel 1. The connecting pipe 42 can be divided into a first section and a second section. One end of the first section is connected to the rainwater collection box 41, and the other end is fixed to the top of the support rod 21. One end of the second section is connected to the first section, and the other end is connected to the water spray pipe. When the water spray pipe moves, the first section remains stationary, and the second section moves with the water spray pipe to avoid the connecting pipe 42 from being separated from the rainwater collection box 41 when the water spray pipe moves. At the same time, the overall distortion of the connecting pipe 42 can be avoided to hinder the movement of other components. The second section can be a telescopic tube such as a bellows, and sufficient length can be reserved to move with the water spray pipe. The battery can be directly installed on the third driving device 9, or a power cord can be connected. The power cord can be fixed to the connecting pipe 42 through a fixing ring to avoid confusion and affect the movement of the photovoltaic panel 1.

[0035] Alternatively, if Figure 1As shown, the rainwater collection box 41 is arranged below the photovoltaic panel 1 and when the photovoltaic panel 1 rotates to a preset angle, rainwater can flow into the rainwater collection box 41 along the photovoltaic panel 1, that is, one end of the photovoltaic panel 1 is inclined toward the rainwater collection box 41 and is located within the range of the rainwater collection box 41, as shown in FIG. Figure 1 If the focusing member 3 is arranged on the side of the photovoltaic panel 1, the angle of the focusing member 3 is adjusted so that rainwater can enter the rainwater collection box 41, and the rainwater falls on the photovoltaic panel 1 and then flows along the photovoltaic panel 1 to the rainwater collection box 41. This is done because the photovoltaic panel 1 has a larger area, collects more rainwater, and can avoid the rainwater collection box 41 from occupying more space.

[0036] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0038] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
