Description

Technical Field

[0001] The present invention relates to the field of photovoltaic devices, and in particular to a modular array photovoltaic device. Background Art

[0002] A modular array photovoltaic system is a new type of photovoltaic system that combines modular design with an array layout. Its core is to achieve efficient power generation, convenient installation, and functional expansion through the flexible combination of standardized units. The modular design is characterized by the integration of independent units, integrating photovoltaic panels, inverters, electrical connectors, and brackets into a single modular unit, allowing each module to operate independently. The modular array also features plug-and-play functionality, with modules connected via standardized interfaces (such as quick-connect plugs and prefabricated cables), eliminating the need for complex wiring and improving installation efficiency. The array layout can be flexible in topology, that is, multiple modular units are arranged in an array form (such as matrix, series-parallel combination), and the layout can be freely adjusted according to the installation area and roof shape (such as L-shaped, stepped array); The brackets installed on the roof to support multiple photovoltaic modules in the modular units are mostly fixed. The inclination angle of the fixed brackets is usually preset according to the local annual average solar altitude angle, but cannot be adjusted with seasonal changes. In summer, the solar altitude angle is large, and the fixed inclination angle will cause the incident angle of noon light to be larger (close to vertical), which will reduce the effective radiation received by the photovoltaic modules. In winter, the solar altitude angle is small, and the fixed inclination angle will cause the incident angle of light to be smaller (close to parallel), which will reduce the actual light-receiving area of the modules. There are also brackets in the existing technology that are equipped with mechanisms to adjust the angle of photovoltaic modules, but most of them are for single or several photovoltaic panels. Array photovoltaic devices usually contain dozens to hundreds of photovoltaic modules. If each module is equipped with an independent drive motor, gearbox or hydraulic rod and other adjustment components, the equipment cost will increase.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 、 Figure 3 、 Figure 4 、 Figure 5、 Figure 7 、 Figure 9 、 Figure 11 、 Figure 12 and Figure 14 A modular array photovoltaic device includes a mounting frame 1, wherein slide rails 11 are symmetrically provided on the surface of the mounting frame 1, and sliders 12 are slidably connected to both ends of the surface of the slide rails 11. A support column 13 is fixedly connected above the slider 12, and a lifting sleeve 14 is sleeved on the outer side of the support column 13, wherein two lifting sleeves 14 are rotatably connected to a first frame plate 15 at one end of the surface away from the mounting frame 1, and the other two lifting sleeves 14 are rotatably connected to a second frame plate 16 at one end of the surface away from the mounting frame 1, and the first frame plate 15 and the second frame plate 16 are slidably connected; The ends of the multiple lifting sleeves 14 away from the mounting frame 1 are all fixedly connected to the first gear 2, the end of the first frame plate 15 close to the second frame plate 16 is symmetrically fixedly connected to the first rack column 3, and the end of the second frame plate 16 close to the first frame plate 15 is symmetrically fixedly connected to the second rack column 4, the two first rack columns 3 are respectively meshed with two of the first gears 2, and the two second rack columns 4 are respectively meshed with the other two first gears 2; A plurality of strip grooves 5 are provided on the surface of the first frame 15 between the two first gears 2. A third rack column 6 is slidably connected to the wall of the strip groove 5. A third gear 7 is equidistantly meshed and connected to the surface of the third rack column 6. A solar panel 8 is fixedly connected between the two third gears 7. A mounting hole 9 is equidistantly provided on the surface of the second frame 16 between the two first gears 2. A rotating plate 10 is mounted on the wall of the mounting hole 9 via a torsion spring. It should be noted that the bracket formed by the mounting frame 1, the support column 13, the first frame 15, the second frame 16 and other structures can support multiple solar panels 8. During use, the angles of multiple solar panels 8 can be adjusted at one time according to local actual conditions. When it snows, the tilt angle of the solar panel 8 can be adjusted to increase, so that snow is not easy to accumulate on the surface of the solar panel 8. When it is windy, the solar panel 8 is adjusted to be parallel to the roof, and the wind can blow more smoothly along the panel surface, reducing the direct action area and front pressure of the wind on the panel surface, thereby reducing the risk of damage to the solar panel 8 and its bracket structure by strong winds, and extending the service life of the bracket and solar panel 8.

[0020] See also Figure 11 The second frame plate 16 is symmetrically provided with connecting grooves 161 on the surface close to the first frame plate 15 , and both connecting grooves 161 are slidably connected to the first frame plate 15 ; It should be noted that the setting of the connecting groove 161 can limit the movement of the first frame plate 15 and the second frame plate 16. When the first frame plate 15 and the second frame plate 16 approach each other or move away from each other, the connecting groove 161 can generate relative movement with the first frame plate 15.

[0021] See also Figure 9 and Figure 10 A spiral groove 131 is provided on the outer side of the support column 13, and a protrusion 132 is installed at the lower end of the wall of the spiral groove 131, and the protrusion 132 is fixedly connected to the inner wall of the lifting sleeve 14; It should be noted that, in the process of adjusting the first frame 15 and the second frame 16 to move closer to or away from each other, the movement of the first rack column 3 and the second rack column 4 can drive the first gear 2 to rotate. When the first frame 15 and the second frame 16 are close to each other, relative movement occurs between the protrusion 132 and the spiral groove 131, and the lifting sleeve 14 can move in the direction away from the mounting frame 1. The bracket formed by the mounting frame 1, the support column 13, the first frame 15, the second frame 16 and other structures rises as a whole, and the solar panel 8 moves accordingly in the direction away from the mounting frame 1, that is, the solar panel 8 is adjusted to move upward. The tilt of the solar panel 8 is adjusted while moving, and a accommodating space can be formed under the solar panel 8 for maintenance personnel to perform operations and maintenance. When the solar panel 8 is parallel to the roof and the adjacent array solar panels 8 are in a tilted state, a space for maintenance personnel to walk can be formed. Compared with using solar panels to cover the entire roof or installing them on the roof through mounting brackets, it is beneficial to maintain the upper surfaces of multiple array photovoltaic device solar panels 8. Before maintenance, observe the direction of the sun, and give priority to maintenance of the array photovoltaic devices close to the direction of sunlight to avoid the formation of radiation shadows and ensure power generation efficiency.

[0022] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , wherein four third gears 7 are rotatably connected to the two first rack columns 3 respectively, wherein ten third gears 7 close to the first frame plate 15 are rotatably connected to the first frame plate 15, and the surfaces of the other sixteen third gears 7 are fixedly connected to rectangular columns 71, and the surfaces of two rectangular columns 71 are sleeved with fixed sleeves 72; It should be noted that the provision of the fixing sleeve 72 can connect multiple solar panels 8 so that the angles of the multiple solar panels 8 can be adjusted simultaneously.

[0023] See also Figure 1 、 Figure 3 、 Figure 12 and Figure 13 A fixing block 51 is fixedly connected to the side of the strip groove 5 away from the second frame plate 16, and a connecting spring 52 is fixedly connected to the surface of the fixing block 51. A circular groove 53 is formed on the end surface of the third rack column 6 close to the fixing block 51, and the end of the connecting spring 52 away from the fixing block 51 is fixedly connected to the wall of the circular groove 53; the initial state of the connecting spring 52 is a stretched state; It should be noted that the elastic force of the connecting spring 52 is used to enable the third rack column 6 to maintain a stable state. During the adjustment and movement of the first frame 15 and the second frame 16, the rotation of multiple third gears 7 close to the side of the second frame 16 can stably drive the third rack column 6 to move, and then drive the remaining third gears 7 to rotate, thereby adjusting the rotation of the solar panel 8.

[0024] See also Figure 1 、 Figure 2 and Figure 11 A horizontal column 121 is fixedly connected between the two sliders 12, and a fourth rack column 122 is fixedly connected to the middle of the surface of the two horizontal columns 121. A fourth gear 123 is meshedly connected between the two fourth rack columns 122. A worm wheel 124 is fixedly connected above the fourth gear 123, and a worm 125 is meshedly connected to the outer side of the worm wheel 124. A connecting frame 126 is rotatably connected to the middle of the surface of the worm 125. The connecting frame 126 is rotatably connected to the fourth gear 123, and the worm 125 is rotatably connected to the mounting frame 1; It should be noted that the arrangement of the worm gear 124 and the worm 125 facilitates position adjustment between the first frame 15 and the second frame 16, thereby controlling the angle adjustment of the solar panel 8. The self-locking function of the worm gear 124 and the worm 125 ensures the stability of the first frame 15 and the second frame 16 after the position adjustment is completed, that is, the stability of the solar panel 8 after the adjustment is completed. Specifically, by adjusting the rotation of the worm 125, the worm wheel 124 is driven to rotate, and the fourth gear 123 rotates as the worm wheel 124 rotates, thereby driving the two fourth racks to move in opposite directions. The two sliders 12 located on the surface of the slide rail 11 approach each other, and the first frame 15 and the second frame 16 are also close to each other. When the angle of the solar panel 8 is adjusted to decrease, the first frame 15 and the second frame 16 can be adjusted away from each other, and the corresponding angle adjustment can be made according to local seasonal changes during actual use.

[0025] See also Figure 7 and Figure 8 The surfaces of the plurality of rotating plates 10 away from the second frame plate 16 are symmetrically provided with inclined grooves 101, the groove walls of the inclined grooves 101 are slidably connected to T-shaped columns 102, the outer sides of the T-shaped columns 102 are sleeved with first springs 103, and the ends of the two T-shaped columns 102 away from the inclined grooves 101 are fixedly connected to L-shaped blocks 104; It should be noted that the arrangement of the L-shaped block 104, the T-shaped column 102 and the first spring 103 can ensure the stability of the solar panel 8 near the second frame 16 during the angle adjustment process; Specifically, in the process of the first frame 15 and the second frame 16 being adjusted to be close to each other, the solar panel 8 and the surface of the rotating plate 10 move relative to each other, and the rotating plate 10 is adjusted to rotate. Then, the rotating plate 10 contacts the surface of the trapezoidal groove 91, and the solar panel 8 contacts the surface of the L-shaped block 104. As the first frame 15 and the second frame 16 continue to move, the L-shaped block 104 and the T-shaped column 102 both move in the direction away from the mounting hole 9, and the first spring 103 is compressed. The elastic force of the first spring 103 is used to enable the solar panel 8 to be in close contact with the L-shaped block 104, thereby ensuring the stability of the solar panel 8 during the adjustment process.

[0026] See also Figure 5 , a trapezoidal groove 91 is provided on the wall of the mounting hole 9; It should be noted that the setting of the trapezoidal groove 91 can limit the rotation adjustment of the rotating plate 10. When the rotating plate 10 contacts the surface of the trapezoidal groove 91, the rotating plate 10 no longer rotates with the movement of the solar panel 8, and the solar panel 8 can contact the surface of the L-shaped block 104.

[0027] It should be noted that an inverter and electrical connectors and other structures can be installed on the surface of the mounting frame 1 below the second frame 16, which are electrically connected to the solar panels 8. The mounting frame 1, support columns 13, lifting sleeves 14, first frame 15 and second frame 16 form a bracket to support multiple solar panels 8; A connecting rod may be fixedly connected to the surface of the third gear 7 , and an end of the connecting rod away from the third gear 7 may be fixedly connected to the side of the solar panel 8 , thereby ensuring stability during angle adjustment of the solar panel 8 .
