Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components and relates to a photovoltaic component. Background Art

[0002] Photovoltaic power generation utilizes the photovoltaic effect at the interface of semiconductors to directly convert sunlight into electricity. The key component is the solar cell. These cells are connected in series and then packaged and protected to form a large-scale photovoltaic power generation system. Combined with components such as a power controller, this creates a photovoltaic power generation device. High places like rooftops and terraces offer less obstruction and therefore offer better sunlight conditions, making them more suitable for installing photovoltaic panels for power generation.

[0003] The existing patent with announcement number CN212115220U discloses a photovoltaic device, whose structural components mainly include: a bottom beam, an inclined beam and a support. The inclined beam is rotatably connected to the bottom beam and a plurality of connection holes are set at one end of the bottom beam. A plurality of connection holes are set at one end of the inclined beam. The two ends of the support are respectively connected to the connection holes on the bottom beam and the inclined beam. By adjusting the connection position of one or both ends of the support, the inclination angle of the inclined beam can be changed, so that the angle of the photovoltaic module can be adjusted, and the efficiency of the photovoltaic module can be maximized. Figure 1 and Figure 2 A similar photovoltaic assembly is also provided, which adjusts the tilt angle by rotating the photovoltaic panels arranged on the support column, thereby achieving an optimal, vertical lighting angle.

[0004] At the same time, in order to improve space utilization and arrange more photovoltaic modules, the distance between adjacent photovoltaic modules is usually shortened. In this case, when the photovoltaic modules are tilted, they will be blocked in front and behind, affecting the working efficiency of the photovoltaic modules behind them. Summary of the Invention

[0005] The purpose of the utility model is to provide a photovoltaic module for solving the problem that when the photovoltaic module adjusts its inclination according to the solar altitude angle, the adjacent photovoltaic modules will block the rear photovoltaic module due to tilt.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A photovoltaic assembly comprises a first photovoltaic unit and a second photovoltaic unit arranged in parallel;

[0008] The first photovoltaic unit and the second photovoltaic unit each include a photovoltaic base and a photovoltaic panel rotatably mounted on the corresponding photovoltaic base;

[0009] The photovoltaic panels in the first photovoltaic unit and the second photovoltaic unit are arranged closely one after the other;

[0010] A first concave arc-shaped slide rail is provided at the bottom of the photovoltaic panel of the first photovoltaic unit; a second concave arc-shaped slide rail is provided at the bottom of the photovoltaic panel of the second photovoltaic unit;

[0011] The photovoltaic base is provided with a driving wheel clamped on the upper and lower sides of the corresponding concave arc-shaped slide rail, and the driving wheel drives the concave arc-shaped slide rail to move backward by rotation, and causes the photovoltaic panel to rotate and tilt;

[0012] The radius of the first concave arc-shaped slide rail is smaller than that of the second concave arc-shaped slide rail, so that at the same photovoltaic panel inclination angle, the backward movement distance of the second concave arc-shaped slide rail is greater than that of the first concave arc-shaped slide rail.

[0013] Furthermore, the ratio of the radius of the first concave arc-shaped slide rail to the radius of the second concave arc-shaped slide rail is 2:3.

[0014] Furthermore, the driving wheel is in frictional contact with the upper and lower sides of the concave arc-shaped slide rail.

[0015] Furthermore, the driving wheel is a rubber wheel.

[0016] Furthermore, the driving wheels are relatively clamped on the upper and lower sides of the concave arc-shaped slide rail.

[0017] Furthermore, the driving wheels are arranged in pairs, and are relatively clamped on the upper and lower sides of the concave arc-shaped slide rail.

[0018] Furthermore, the driving wheels are arranged in a triangle shape and clamped on the upper and lower sides of the concave arc-shaped slide rail.

[0019] Furthermore, the photovoltaic base is also provided with auxiliary support wheels, which support the concave arc-shaped slide rail from the bottom, or are clamped on the upper and lower sides of the concave arc-shaped slide rail.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The utility model utilizes the characteristics that the arc-shaped slide rail also displaces while rotating around its center of circle, and that arcs of different radii have different displacement distances when the rotation angles are the same. While the photovoltaic panel is rotated and tilted by the concave arc-shaped slide rail, the front and rear photovoltaic panels are also moved backward, and the displacement spacing of the rear photovoltaic panel is increased, thereby avoiding the problem of mutual obstruction between adjacent photovoltaic panels when they are tilted.

[0030] The following embodiments are implemented based on the above technical solution of the present invention, and provide detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to the following embodiments.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0032] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0033] Example

[0034] like Figure 3 and Figure 4As shown, a photovoltaic assembly comprises a first photovoltaic unit and a second photovoltaic unit arranged in parallel; wherein the first photovoltaic unit and the second photovoltaic unit both comprise a photovoltaic base 3, and a photovoltaic panel 2 rotatably arranged on the corresponding photovoltaic base 3; the photovoltaic panels 2 in the first photovoltaic unit and the second photovoltaic unit are arranged closely one after the other; a first concave arc-shaped slide rail 4 is provided at the bottom of the photovoltaic panel 2 of the first photovoltaic unit; a second concave arc-shaped slide rail 5 is provided at the bottom of the photovoltaic panel 2 of the second photovoltaic unit; a driving wheel 6 is provided on the photovoltaic base 3 which is clamped at the upper and lower sides of the corresponding concave arc-shaped slide rail, and the driving wheel 6 drives the concave arc-shaped slide rail to move backward by rotation, and causes the photovoltaic panel 2 to rotate and tilt; the radius of the first concave arc-shaped slide rail 4 is smaller than that of the second concave arc-shaped slide rail 5, so that under the same inclination angle of the photovoltaic panel 2, the backward movement distance of the second concave arc-shaped slide rail 5 is greater than that of the first concave arc-shaped slide rail 4.

[0035] This embodiment utilizes the characteristics that the arc-shaped slide rail also displaces while rotating around its center, and that the displacement distances are different when the arc-shaped angles of different radii are the same. While the photovoltaic panel 2 is rotated and tilted by the concave arc-shaped slide rail, the front and rear photovoltaic panels 2 are also moved backward, and the displacement spacing of the rear photovoltaic panel 2 is increased, thereby avoiding the problem of mutual obstruction between adjacent photovoltaic panels while tilting.

[0036] In some specific embodiments, the ratio of the radius of the first concave arc-shaped slide rail 4 to the radius of the second concave arc-shaped slide rail 5 is 2:3. Figure 3 As shown, when the front-to-back length of the photovoltaic panel 2 is 7.7 units, the radius of the first concave arc-shaped slide rail 4 is 3.95 units, the radius of the second concave arc-shaped slide rail 5 is 6.08 units, and the spacing between the photovoltaic panels 2 is 0.15 units, the photovoltaic panel 2 is rotated 25 degrees, as shown in FIG. Figure 4 As shown, the spacing between the photovoltaic panels 2 along the direction of sunlight can still be maintained at 0.31 units. Figure 2 As shown, there is an overlap of about 0.58 units between the two photovoltaic panels.

[0037] In some specific embodiments, the driving wheels 6 are in frictional contact with the upper and lower sides of the concave arc-shaped slide rail, and more specifically, rubber wheels are used. This frictional contact can effectively transmit driving force to drive the concave arc-shaped slide rail to rotate and move, and can also serve as a limiter to maintain the inclination angle of the photovoltaic panel 2.

[0038] More specifically, the driving wheel 6 is driven by a servo motor and / or braked by a transmission mechanism with a braking function.

[0039] More preferably, a brake pad is arranged along the bending direction on the bottom side of the concave arc-shaped slide rail, and a friction clamp adapted to the brake pad is provided on the second base 3. The photovoltaic panel 2 maintains the inclination angle through the clamping friction action of the brake pad and the friction clamp, and the inclination angle can be adjusted by loosening the friction clamp.

[0040] In some specific embodiments, such as Figure 5 As shown, the driving wheels 6 are clamped on the upper and lower sides of the concave arc-shaped slide rail. More preferably, the spacing between the driving wheels 6 on the same side can be adjusted according to actual needs to ensure the smoothness of the rotation of the concave arc-shaped slide rail.

[0041] In some specific embodiments, a clearance groove may be provided on the second base 3 to allow the lower driving wheel 6 to rotate smoothly.

[0042] In some specific embodiments, the driving wheels 6 are arranged in pairs, and are clamped relatively on the upper and lower sides of the concave arc-shaped slide rail, one above and one below.

[0043] In some specific embodiments, the driving wheels 6 are arranged in a triangle shape and clamped on the upper and lower sides of the concave arc-shaped slide rail.

[0044] In some specific embodiments, the second base 3 is further provided with auxiliary support wheels, which support the concave arc-shaped slide rail from the bottom, or are clamped on the upper and lower sides of the concave arc-shaped slide rail. Figure 3 The method shown is arranged on a slope, and the slope inclination is determined according to the variation range of the solar altitude angle during the effective illumination time and the effective inclination adjustment range of the first photovoltaic unit and the second photovoltaic unit, so that at noon, the sun directly shines on the first photovoltaic panel 2 and the photovoltaic panel 2, and the first photovoltaic unit and the second photovoltaic unit are in the middle position of the inclination adjustment range.

[0045] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this utility model without departing from the scope of this utility model should be within the scope of protection of this utility model.
