Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, in particular to an angle-adjustable photovoltaic power generation group. Background Art

[0002] Photovoltaic generator sets are power generation systems that use solar panels to absorb sunlight and convert solar radiation energy into electrical energy through the photoelectric effect. Photovoltaic power generation is a clean and renewable form of energy and has a relatively wide range of applications. When using existing photovoltaic generator sets, the photovoltaic panels are usually installed on the corresponding mounting structure. Because the angle of sunlight is constantly changing, the angle between the sunlight angle and the photovoltaic panel surface is small in the morning and evening, and the sunlight utilization rate is relatively low. In snowy weather, snow accumulates on the photovoltaic panels, which easily blocks the panels. On sunny days, it takes a certain amount of time for the snow to melt, which easily affects the power generation efficiency. At the same time, in freezing rain weather, ice is also prone to appear on the photovoltaic panels. The ice will block the sunlight and affect the power generation efficiency. In addition, when the ice melts, water droplets may flow down the solar panels, posing certain safety hazards to the equipment and personnel below. Summary of the Invention

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] See also Figure 1-5 In an embodiment of the present invention, an angle-adjustable photovoltaic power generation unit includes a plurality of adjustment modules 100, a driving module 200, and a plurality of linkage modules 300;

[0044] Several adjustment modules 100 are used to adjust the angle of the photovoltaic module. The adjustment module 100 includes a fixed frame 110. A photovoltaic panel 120 is arranged inside the fixed frame 110. A fixing seat 112 is fixedly connected to the bottom surface of the fixed frame 110. Two support rods 130 are provided at the bottom of the fixed frame 110. An adjustment mechanism 150 is provided on the top of the support rod 130. The adjustment mechanism 150 includes a support frame 151. The bottom surface of the support frame 151 is fixedly connected to the top surface of the adjacent support rod 130. The inner side surface of the support frame 151 is slidably connected to the sliding rod 152. The sliding rod 152 can move up and down relative to the support frame 151. The inner side surface of the fixing seat 112 is fixedly connected to a fixing rod 114 that is rotatably connected to the inner side surfaces of the two sliding rods 152. The fixed frame 110 can rotate relative to the sliding rod 152.

[0045] A shielding plate 111 is fixedly connected to the top side of the fixed frame 110, and two support rods 113 fixedly connected to the bottom surface of the fixed frame 110 are fixedly connected to both sides of the fixed base 112. The fixed base 112 can support the fixed frame 110 through the support rods 113, and the support rods 113 can improve the stability of the fixed frame 110;

[0046] The driving module 200 is used to provide power for adjusting the angle;

[0047] Several linkage modules 300 are respectively arranged between two adjacent adjustment modules 100 and between the driving module 200 and the adjacent adjustment module 100. The linkage module 300 is used to transmit power. Several adjustment modules 100 can be placed in a row, and the two adjacent adjustment modules 100 can be connected through the linkage module 300. At the same time, the driving module 200 can be placed on one side, and the driving module 200 can be connected to the adjacent adjustment module 100 through the linkage module 300. The driving module 200 can provide power for adjusting the angle of the photovoltaic panels 120 of several adjustment modules 100 through the linkage module 300.

[0048] Specifically, in the morning and evening, the angle of the photovoltaic panel 120 can be adjusted according to the angle of sunlight, and the sunlight can be made to shine vertically on the photovoltaic panel 120 as much as possible, which is beneficial to improving the utilization rate of sunlight by the photovoltaic panel 120 and improving the power generation efficiency. In snowy and freezing rainy weather, the fixed frame 110 and the photovoltaic panel 120 can be moved upward first, and then the fixed frame 110 can be rotated to make the fixed frame 110 in a vertical state or the back of the fixed frame 110 face upward, and the shielding plate 111 is located on the top of the fixed frame 110. At this time, rainwater can fall from the edge of the shielding plate 111, and snowflakes can fall on the shielding plate 111, and the photovoltaic panel 120 is shielded by the shielding plate 111. At the same time, snowflakes and rainwater will also fall on the back of the fixed frame 110, which can prevent rain and snow from contacting the photovoltaic panel 120, and snowflakes will not accumulate on the photovoltaic panel 120. At the same time, it prevents rain from contacting the photovoltaic panel 120 and ice from forming on the surface of the photovoltaic panel 120. When the weather is clear, the impact on the power generation efficiency of the photovoltaic panel 120 can be reduced. When the photovoltaic panel 120 is tilted or erected, the amount of rain and snow accumulated on the back of the fixing frame 110 is relatively small. When the weather is clear, after adjusting the fixing frame 110 to its original angle, when the back of the fixing frame 110 is facing downward again, the snow on the back of the fixing frame 110 will fall directly. This can minimize the situation where the load on the fixing frame 110 is increased due to snow accumulation, and there is no need for staff to manually clean the snow, which is beneficial to reducing the burden on staff. At the same time, in hail weather, turning the back of the fixing frame 110 downward and the photovoltaic panel 120 downward can also minimize the impact of hail on the photovoltaic panel 120, which is beneficial to increasing the service life of the photovoltaic panel 120.

[0049] Example 1

[0050] like Figure 4-5 As shown, in this embodiment, the bottom of the inner side surface of the support frame 151 is rotatably connected to an adjustment screw rod 153 extending to the inside of the sliding rod 152, the bottom of the side surface of the adjustment screw rod 153 is rotatably connected to the inner side surface of the adjacent support rod 130, and the inner side surface of the bottom of the sliding rod 152 is fixedly connected to a screw-on rod 1521 that is screwed together with the side surface of the adjustment screw rod 153, and the adjustment screw rod 153 passes through the inside of the screw-on rod 1521.

[0051] The side of the fixed rod 114 is located inside the two sliding rods 152 and is fixedly sleeved with a bevel gear 115; the inner side of the sliding rod 152 is rotatably connected to a transmission rod 155, which is a hollow rod. The adjusting screw 153 extends to the inside of the transmission rod 155, and the top of the side of the transmission rod 155 is fixedly sleeved with a bevel gear 4 1551 that meshes with the adjacent bevel gear 115 for transmission. The bottom of the inner side of the sliding rod 152 is rotatably connected to a rotating shaft 156, and the bottom of the side of the transmission rod 155 and the side of the rotating shaft 156 are both fixedly sleeved with a bevel gear 5 159, and two adjacent bevel gears 5 159 are meshed for transmission. The side of the rotating shaft 156 is located outside the sliding rod 152 and is fixedly sleeved with a connecting gear 157. The bottom of the inner side of the support frame 151 is fixedly connected with a rack 1511 that meshes with the connecting gear 157 for transmission.

[0052] During specific implementation, the top edge of the adjusting screw rod 153 can extend to the inside of the transmission rod 155, and the inside of the screw rod 1521 is screwed with the side of the adjusting screw rod 153. The adjusting screw rod 153 can limit the position of the screw rod 1521, thereby limiting the height of the sliding rod 152, and the connecting gear 157 is engaged with the rack 1511. When the height of the sliding rod 152 remains unchanged, the rack 1511 can prevent the connecting gear 157 from rotating, thereby preventing the rotating shaft 156 from rotating. The rotating shaft 156 can prevent the transmission rod 155 from rotating through the bevel gear five 159, and the transmission rod 155 can prevent the fixed rod 114 from rotating through the bevel gear four 1551 and the bevel gear one 115. The fixed rod 114 can prevent the fixing seat 112 from rotating, thereby maintaining the angle between the fixing frame 110 and the photovoltaic panel 120. When the angle of the photovoltaic panel 120 is to be adjusted according to sunlight, the adjusting screw rod 153 can be rotated. Since the sliding rod 152 can prevent the screwing rod 1521 from rotating, the screwing rod 1521 can move up and down along the adjusting screw rod 153, and the screwing rod 1521 then drives the sliding rod 152 to move. The sliding rod 152 can drive the rotating shaft 156 to move, so that the connecting gear 157 rolls on the rack 1511, so that the rotating shaft 156 rotates. The rotating shaft 156 can drive the transmission rod 155 to rotate through the bevel gear five 159, and the transmission rod 155 can drive the fixing rod 114 to rotate through the bevel gear four 1551 and the bevel gear one 115. The fixing rod 114 can drive the fixing seat 112 to rotate, and the fixing seat 112 can drive the fixing frame 110 to rotate, thereby adjusting the angle of the photovoltaic panel 120.

[0053] like Figure 4 As shown, in this embodiment, a stop block 158 is fixedly connected to the side of the rotating shaft 156 away from the sliding rod 152, and a limiting rod 1513 is fixedly connected to the inner side surface of the support frame 151 corresponding to the stop block 158. The top surface of the limiting rod 1513 is fixedly connected to an arc block 1514 fixedly connected to the inner side surface of the support frame 151, and the top of the inner side surface of the support frame 151 is fixedly connected to the gear 157 corresponding to the rack 2 1512.

[0054] When the fixing frame 110 is tilted, the adjusting screw 153 is rotated continuously to move the sliding rod 152 upward. After the connecting gear 157 is disengaged from the rack 1511, the stopper 158 will contact the side of the limit rod 1513. At this time, the fixing frame 110 is in a tilted state, and the photovoltaic panel 120 is still at the top of the fixing frame 110. Since the fixing seat 112 is at the side of the shielding plate 111 at the bottom of the fixing frame 110, the side of the stopper 158 can keep in contact with the side of the limit rod 1513 under the action of gravity. The limit rod 1513 can prevent the stopper 158 from continuing to rotate, so that the fixing frame 110 can remain tilted. After the stopper 158 moves upward to the top of the limit rod 1513, the side of the stopper 158 The surface will disengage from the side of the limit rod 1513, and then the stop block 158 will contact the arc surface of the arc block 1514. As the sliding rod 152 gradually rises, under the action of the gravity of the fixed frame 110, the stop block 158 will gradually rotate, so that the fixed frame 110 is in a vertical state, and then the sliding rod 152 continues to drive the rotating shaft 156 and the connecting gear 157 to move upward, which will disengage the stop block 158 from the arc block 1514, and then the connecting gear 157 will engage with the rack 2 1512. When the sliding rod 152 continues to move upward, the connecting gear 157 can roll on the rack 2 1512, causing the rotating shaft 156 to rotate, thereby causing the fixed frame 110 to continue to rotate, so that the fixed frame 110 is in a tilted state, and the back of the fixed frame 110 is facing upward, so that the photovoltaic panel 120 is facing downward, so that the photovoltaic panel 120 can be protected by the fixed frame 110.

[0055] Example 2

[0056] Based on the first embodiment, Figure 3 and Figure 8As shown, in this embodiment, the adjustment module 100 also includes a connecting rod 140, which is fixedly connected between the two support rods 130. The inner side of the connecting rod 140 is rotatably connected to a transmission shaft 141 that is rotatably connected to the inner sides of the two support rods 130. The side of the transmission shaft 141 is located inside the two support rods 130 and is fixedly sleeved with a bevel gear 2 142; the bottom of the side of the adjusting screw rod 153 is located inside the support rod 130 and is fixedly sleeved with a bevel gear 3 154, and the bevel gear 3 154 is engaged with the adjacent bevel gear 2 142 for transmission.

[0057] The adjustment module 100 further includes two universal joints 160, which are fixedly connected to both ends of the transmission shaft 141. The opposite sides of the two support rods 130 are rotatably connected to the adjacent universal joints 160. The ends of the two universal joints 160 that are away from each other are fixedly connected to the plug-in block 161.

[0058] The linkage module 300 includes a linkage rod 310, a toggle block 320, and two rectangular blocks 330;

[0059] Two open slots are provided on the side of the linkage rod 310; the toggle block 320 is rotatably connected to the inside of the linkage rod 310 corresponding to the open slots, and the inner side of the toggle block 320 is fixedly connected to the bidirectional screw rod 321; the two rectangular blocks 330 are respectively slidably connected to the two sides of the inside of the linkage rod 310, and the inner side of the rectangular block 330 is screwed together with the side of the bidirectional screw rod 321, and the inner side of the plug-in block 161 is slidably connected to the side of the adjacent rectangular block 330.

[0060] When the two adjusting modules 100 are put into a row, the linkage module 300 can be moved between the universal joints 160 of the two adjacent adjusting modules 100. Then, the toggle block 320 can be rotated through the opening slot. The toggle block 320 can drive the bidirectional screw rod 321 to rotate. When the bidirectional screw rod 321 rotates, the two rectangular blocks 330 can be moved back to each other, so that the rectangular block 330 extends out. By setting the universal joint 160, the angle of the plug-in block 161 can be adjusted arbitrarily, so that the plug-in block 161 is aligned with the adjacent rectangular block 330, so that the rectangular block 330 can be smoothly inserted into the adjacent plug-in block 161, and the rectangular block 330 can be against the end of the universal joint 160. In this way, when the two adjacent adjusting modules 100 are installed at an angle due to terrain restrictions, the linkage module 300 can also be connected to the plug-in block 161. Since the outer contour of the cross section of the rectangular block 330 is Rectangular, so that when the connecting rod 140 of an adjustment module 100 is rotated, the connecting rod 140 can drive the plug-in block 161 to rotate through the universal joint 160, the plug-in block 161 can drive the linkage rod 310 to rotate through the rectangular block 330, and the linkage rod 310 can drive the plug-in block 161 of another adjustment module 100 to rotate through the rectangular block 330, and the plug-in block 161 can drive the connecting rod 140 to rotate through the universal joint 160, so that the connecting rods 140 of the two adjacent adjustment modules 100 are linked through the linkage module 300, and when the connecting rod 140 rotates, the connecting rod 140 can drive the adjusting screw 153 to rotate through the bevel gear 2 142 and the bevel gear 3 154, so that the sliding rod 152 is raised and lowered to adjust the angle of the fixed frame 110 and the photovoltaic panel 120, so that a row of adjustment modules 100 can synchronously adjust the angle of the photovoltaic panel 120.

[0061] like Figure 6-8 As shown, in this embodiment, the driving module 200 includes a connection box 210, a power motor 220, a driving shaft 1 230, a driving shaft 2 240, two transmission gears 250, and a universal joint 260;

[0062] The inner side of the connecting box 210 is fixedly connected to the support frame 211; the power motor 220 is fixedly connected to the top surface of the support frame 211; the drive shaft 1 230 is rotatably connected to the inner side of the connecting box 210, and the output end of the power motor 220 is transmission-connected to the end of the drive shaft 1 230; the drive shaft 2 240 is rotatably connected to the inner side of the connecting box 210, and the end of the drive shaft 2 240 is rotationally connected to the side of the support frame 211; the two transmission gears 250 are respectively fixedly sleeved on the drive shaft 1 230 and the drive shaft 2 240, and the two transmission gears 250 are engaged for transmission; the universal joint 260 is fixedly connected to one end of the drive shaft 2 240 located outside the connecting box 210, and one end of the universal joint 260 is fixedly connected to the plug-in block 261 which is slidingly connected to the side of the adjacent rectangular block 330.

[0063] In a specific implementation, the driving module 200 can be set on one side of a row of adjustment modules 100, and a linkage module 300 can be placed between the universal joint 260 and the adjacent universal joint 1 160. The toggle block 320 is rotated to make the rectangular block 330 extend out of the linkage rod 310, so that one rectangular block 330 of the linkage module 300 is inserted into the plug-in block 2 261, and the other rectangular block 330 of the linkage module 300 is inserted into the adjacent plug-in block 1 161, so that the universal joint 260 is connected to the universal joint 1 160 through the linkage module 300, and the drive shaft 1 230 can be driven to rotate by the power motor 220. The drive shaft 1 230 can be driven to rotate by the power motor 220. The transmission gear 250 drives the driving shaft 240 to rotate. The rotation of the driving shaft 240 can drive the universal joint 260 to rotate. The universal joint 260 can drive the adjacent rectangular block 330 to rotate through the plug-in block 261. The rectangular block 330 can drive the linkage rod 310 to rotate. The linkage rod 310 can drive the adjacent plug-in block 1 161 to rotate through the rectangular block 330, thereby rotating the universal joint 160 and the connecting rod 140. The connecting rods 140 of several adjustment modules 100 can rotate synchronously through the linkage module 300.
