Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and particularly to a solar photovoltaic bracket. Background Art

[0002] A solar photovoltaic bracket is a support structure used to place, install, and fix solar panels in a solar photovoltaic power generation system.

[0003] In the prior art, a solar photovoltaic bracket is usually a fixed structure, and a photovoltaic panel is installed on the solar photovoltaic bracket in an inclined state. After retrieval, Chinese Patent with the publication number CN221886335U discloses a photovoltaic bracket and a photovoltaic bracket assembly. Among them, the photovoltaic bracket includes: a bracket body having a crimping bottom surface and an installation top surface located above the crimping bottom surface and inclined. The installation top surface is used to install a photovoltaic module. Under the action of the wind pressure generated when the wind blows onto the installation top surface and the self-weight of the bracket body, the bracket body is crimped to the surface to be installed through the crimping bottom surface. The above solution can effectively solve the problem that the photovoltaic bracket in the prior art will damage the surface to be installed during installation. However, when the above solution is actually used, there are still the following deficiencies:

[0004] When the photovoltaic bracket proposed by the above solution is actually used, when the inclined photovoltaic panel is subjected to a large wind force, it will increase the wind pressure load of the photovoltaic bracket system. This increased wind pressure may cause the photovoltaic bracket to bear greater pressure, thereby affecting its structural stability. Excessive wind pressure may even cause the photovoltaic bracket to deform, loosen or be damaged, thereby threatening the stability of the photovoltaic panel.

[0023] Preferably, the transmission ratio between the second gear and the third gear is less than 1.

[0024] Advantages of the present invention:

[0025] 1. Through the intelligent control system integrating the wind speed sensor and the driving cylinder, self - protection of the photovoltaic panel under strong wind conditions is achieved. Under normal circumstances, the photovoltaic panel remains in an inclined state to maximize sunlight reception. However, when the wind speed sensor detects excessive wind speed, the system can respond quickly. By driving the meshing transmission of the rack and the first gear through the driving cylinder, the photovoltaic panel is smoothly rotated to a horizontal state. This transformation significantly reduces the windward area of the photovoltaic panel, effectively reduces the impact of strong wind on it, thus avoiding possible structural damage and extending the service life of the photovoltaic panel. At the same time, this design also ensures the safe and stable operation of the entire photovoltaic system under extreme weather conditions. When the wind speed weakens, the wind speed sensor comes into play again, controlling the driving cylinder to reset. By driving the rack and the first gear in the reverse direction, the photovoltaic panel is restored to the inclined state again to ensure that it can continue to receive sunlight at the best angle and maximize the power generation efficiency;

[0026] 2. The rotational characteristics bring great convenience to the maintenance of the photovoltaic panel. Especially in snowy weather, the surface of the photovoltaic panel is easily covered with snow, affecting the power generation efficiency. The staff can utilize the rotatability of the rotating frame and, through a series of delicate mechanical linkages (such as tie rods, positioning toothed plates, positioning gears, connecting frames, cylinder mounting frames, etc.), easily flip the driving cylinder and the rack by 180°, and then drive the photovoltaic panel to rotate to a more inclined position. During this process, the snow will naturally slide off under the action of gravity, achieving rapid cleaning without the need for manual climbing or other tools, greatly improving the cleaning efficiency and safety;

[0027] 3. Through the linkage of the push block, rotating cylinder, first shaft body, second gear, third gear, second shaft body and eccentric wheel, the rotation of the rotating shaft is successfully converted into the up - and - down reciprocating motion of the first push rod. This conversion process is not only accurate and efficient but also makes full use of the principle of mechanical transmission to achieve effective energy transfer and conversion. Secondly, the up - and - down reciprocating motion of the first push rod drives the movement of the photovoltaic panel mounting frame, and then causes the photovoltaic panel to generate a vibration effect during rotation. This vibration mechanism has a significant effect on removing the snow covering the surface of the photovoltaic panel. The snow is more likely to slide off the photovoltaic panel under the action of vibration, thus greatly improving the cleaning efficiency and cleanliness;

[0028] 4. Through the linkage of the pull rod and the positioning tooth plate, flexible control of the positioning gear is achieved. When snow removal is required, the staff can easily release the restriction of the positioning tooth plate on the positioning gear by pulling up the pull rod, enabling the positioning gear to rotate freely. When the positioning tooth plate resets and meshes with the positioning gear again, this mechanism provides a firm fixing effect. This fixing not only ensures the stability of the shaft rod, drive cylinder, and rack during operation but also prevents accidental rotation caused by vibration or other external factors, thus guaranteeing the safety and reliability of the entire snow removal process.

[0047] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in conjunction with specific embodiments.

Terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "upper", "lower", "left", "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0049] Such as Figures 1 to 15As shown in the figure, the solar photovoltaic support includes two fixed bases 1, a rotating frame 2, a photovoltaic panel mounting frame 4, two fixing plates 6, a driving structure, a flipping structure, a vibration structure and a transmission unit. The two fixed bases 1 are arranged opposite to each other. The rotating frame 2 is rotatably mounted on the two fixed bases 1 through a rotating shaft 3. The two fixing plates 6 are respectively fixed at both ends of the rotating frame 2;

[0050] As Figure 5 , Figure 14 shown in the figure, the photovoltaic panel mounting frame 4 is slidably assembled on the rotating frame 2 through a sliding structure. The sliding structure includes a plurality of slide rails 51 and a plurality of sliders 52. Each slide rail 51 is fixed on the rotating frame 2. The plurality of sliders 52 are respectively slidably assembled on the plurality of slide rails 51. Each slider 52 is fixedly connected to the photovoltaic panel mounting frame 4. The cross-sections of the slide rail 51 and the slider 52 are both in a T-shaped structure. The plurality of slide rails 51 are distributed in a linear array;

[0051] As Figure 3 shown in the figure, the driving structure is arranged on one of the fixed bases 1 and is used to drive the rotating frame 2 to rotate. The driving structure includes a driving cylinder 72. The driving structure further includes a cylinder mounting frame 71, a rack 73 and a first gear 74. The driving cylinder 72 is mounted on the cylinder mounting frame 71. The rack 73 is fixed on the output end of the driving cylinder 72. The first gear 74 is fixedly sleeved on the rotating shaft 3. The first gear 74 is arranged opposite to the rack 73. The rack 73 is slidably assembled on the cylinder mounting frame 71 through a guide rail and a sliding seat;

[0052] When the solar photovoltaic bracket proposed by the present invention is in use, the photovoltaic panel is installed on the photovoltaic panel mounting frame 4. Under normal circumstances, the rotating frame 2 and the photovoltaic panel are both in an inclined state. A wind speed sensor (proposed as prior art, not shown in the figure and not elaborated here) is installed on one of the fixed bases 1. When the wind speed sensor detects that the wind speed is too high, the wind speed sensor sends a control signal to the driving cylinder 72, causing the driving cylinder 72 to operate. When the driving cylinder 72 operates, it can drive the rack 73 to move. During the movement of the rack 73, it will engage with the first gear 74 and drive the first gear 74 to rotate. When the first gear 74 rotates, it can drive the rotating shaft 3 to rotate, which causes the rotating frame 2 and the photovoltaic panel to rotate accordingly. When the telescopic end of the driving cylinder 72 extends to the maximum extent, the rotating frame 2 and the photovoltaic panel just rotate to the horizontal state. When the photovoltaic panel is in the horizontal state, the windward area of the photovoltaic panel will be greatly reduced. At this time, the windward area of the photovoltaic panel is significantly reduced, effectively reducing the impact of strong wind on the photovoltaic panel, thereby protecting the photovoltaic panel from damage, extending its service life, and ensuring the safe and stable operation of the entire system. When the wind speed sensor detects that the wind speed becomes smaller, the wind speed sensor controls the driving cylinder 72 to reset, causing the rack 73 to reset accordingly. When the rack 73 resets, it can drive the first gear 74 to rotate in the reverse direction. When the driving cylinder 72 is completely reset, the rotating frame 2 and the photovoltaic panel will rotate to the inclined state again to ensure that the photovoltaic panel obtains the best light-receiving angle. It should be noted that the specific control method of the wind speed sensor for the driving cylinder 72 is prior art and will not be elaborated here. In addition, the specific trigger value of the wind speed sensor can be obtained through experiments;

[0053] As Figure 3 , Figure 9 , Figure 10 shown, the flipping structure is arranged on one of the fixed bases 1 and is used to adjust the position of the driving cylinder 72. The flipping structure includes a first fixing frame 81, a shaft rod 82, a connecting frame 83, a positioning gear 84, a positioning toothed plate 85 and a pull rod 86. The first fixing frame 81 is fixed on the fixed base 1. The shaft rod 82 passes through the first fixing frame 81 and is rotatably connected to the first fixing frame 81. The shaft rod 82 and the rotating shaft 3 are coaxially arranged. One end of the connecting frame 83 is fixedly sleeved on the shaft rod 82, and the other end is fixedly connected to the cylinder mounting frame 71. The positioning gear 84 is fixedly sleeved on the shaft rod 82. The pull rod 86 passes through the first fixing frame 81 and is slidably connected to the first fixing frame 81. The positioning toothed plate 85 is fixed at the bottom end of the pull rod 86. A plurality of teeth adapted to the positioning gear 84 are arranged on the positioning toothed plate 85. The positioning toothed plate 85 and the first fixing frame 81 are connected by a connecting spring 87;

[0054] In the present invention, the rotating frame 2 and the photovoltaic panel mounting frame 4 are designed to be rotatable. On the one hand, this is beneficial to reducing the impact of strong winds on the stability of the photovoltaic support. On the other hand, the staff can also utilize this characteristic to remove snow from the photovoltaic panels. When it snows, a layer of snow will cover the surface of the photovoltaic panels. The staff can use the rotatable characteristic of the rotating frame 2 to clean the snow on the photovoltaic panels. Specifically, when it is necessary to clean the snow covering the photovoltaic panels, the staff first pull up the pull rod 86, causing the pull rod 86 to drive the positioning toothed plate 85 to move upward until the positioning toothed plate 85 is separated from the positioning gear 84. Without the restriction of the positioning toothed plate 85, the positioning gear 84 can rotate freely. At this time, the staff can manually control the rotation of the connecting frame 83. When the connecting frame 83 rotates, it can drive the cylinder mounting frame 71 to rotate, and the related structures designed on the cylinder mounting frame 71 will also rotate accordingly until the driving cylinder 72 and the rack 73 rotate 180°. In addition, a pointer is fixed at the end of the shaft rod 82, and two scale lines are provided on the side of the first fixing frame 81. In the initial state, the pointer aligns with one of the scale lines. When the shaft rod 82 rotates, it drives the pointer to rotate. When the pointer aligns with the other scale line, it means that the driving cylinder 72 and the rack 73 have just rotated 180°. Therefore, the staff can accurately control the rotation angle of the shaft rod 82 through the pointer and the two scale lines. When the driving cylinder 72 and the rack 73 rotate 180°, the staff releases the pull rod 86, and the positioning toothed plate 85 is reset under the elastic force of the connecting spring 87. When the positioning toothed plate 85 is reset, the positioning toothed plate 85 meshes with the positioning gear 84 again. At this time, the positioning toothed plate 85 and the positioning gear 84 play a fixing role, and the position of the shaft rod 82 will also be fixed. When the shaft rod 82 is fixed, the driving cylinder 72 and the rack 73 are fixed accordingly. This fixing mechanism can ensure the stability of the driving cylinder 72 and the rack 73 during operation;

[0055] When the driving cylinder 72 and the rack 73 complete the flipping, the staff manually controls the operation of the driving cylinder 72 to move the rack 73. Since the rack 73 has flipped 180°, the rack 73 can drive the first gear 74 to rotate in the reverse direction, causing the rotating shaft 3 to rotate in the reverse direction. When the rotating shaft 3 rotates, the rotating frame 2 and the photovoltaic panel rotate accordingly. During this process, the inclination degree of the photovoltaic panel will gradually increase, and the snow covering the surface of the photovoltaic panel will slide off the photovoltaic panel under the action of gravity. Therefore, the staff can quickly clean the snow covering the surface of the photovoltaic panel by controlling the inclination angle of the photovoltaic panel;

[0056] As Figure 11 、 Figure 15As shown in the figure, the vibration structure is arranged on one of the fixing plates 6 and is used to drive the photovoltaic panel mounting frame 4 to vibrate. The vibration structure includes a pull rope 91, a pulley 92, a counterweight 93, a push rod 94, a fixing block 95, a side plate 96 and a vibrating member 97. The pull rope 91 passes through the hole formed in the fixing plate 6. One end of the pull rope 91 is connected to the photovoltaic panel mounting frame 4, and the other end is connected to the counterweight 93. The pulley 92 is installed on the side of the fixing plate 6, and the pull rope 91 bypasses the pulley 92. The push rod 94 passes through the fixing plate 6 and is slidably connected to the fixing plate 6. One end of the push rod 94 is fixedly connected to the photovoltaic panel mounting frame 4, and the other end is fixedly connected to the fixing block 95. An inclined surface is provided on the fixing block 95. The side plate 96 is fixed to the side of the fixing plate 6, and the vibrating member 97 is fixed to the side plate 96. The vibrating member 97 is arranged opposite to the inclined surface of the fixing block 95. The vibrating member 97 includes a first sealing cylinder, a first push rod and a first spring. The first sealing cylinder is fixed to the side plate 96. The first push rod is movably inserted into the first sealing cylinder. One end of the first push rod extends to the outside of the first sealing cylinder and is arranged opposite to the inclined surface of the fixing block 95. The first sealing cylinder and the first push rod are connected by the first spring. The outer surface of the first push rod and the inner surface of the first sealing cylinder are in mutual contact;

[0057] As Figure 12 shown in the figure, the transmission unit is composed of a rotating structure and a gas supply structure. The rotating structure is driven by the rotating shaft 3. When the rotating structure operates, it drives the gas supply structure to perform a periodic gas supply action. The rotating structure includes a second fixing frame 101, a rotating cylinder 102, a push block 103, a stop block 104, a first shaft body 105 and a second shaft body 106. The second fixing frame 101 is fixed on the fixed base 1, and a through hole is formed in the second fixing frame 101. The rotating cylinder 102 is rotatably installed in the through hole. The rotating cylinder 102 is located between the rotating shaft 3 and the shaft rod 82 and is coaxially arranged with the rotating shaft 3. One end of the rotating shaft 3 extends into the interior of the rotating cylinder 102. The push block 103 is fixed on the rotating shaft 3. The stop block 104 is fixed on the inner surface of the rotating cylinder 102. The first shaft body 105 is fixed on the rotating cylinder 102 and is coaxially arranged with the rotating cylinder 102. The second shaft body 106 is rotatably installed on the side of the second fixing frame 101. A second gear 107 is fixedly sleeved on the first shaft body 105. A third gear 108 is fixedly sleeved on the second shaft body 106. The second gear 107 and the third gear 108 are meshed with each other, and the transmission ratio of the second gear 107 to the third gear 108 is less than 1;

[0058] As Figure 3 、 Figure 8 、 Figure 13As shown in the figure, the air supply structure includes an eccentric wheel 111, two connecting seats 112, an air supply member 113 and a connecting pipe 114. The eccentric wheel 111 is fixedly sleeved on the second shaft body 106, and the eccentric wheel 111 is eccentrically arranged with respect to the second shaft body 106. The air supply member 113 is fixed on the side surface of the second fixing frame 101 through the two connecting seats 112, and the air supply member 113 is arranged opposite to the eccentric wheel 111. One end of the connecting pipe 114 is communicated with the air supply member 113, and the other end is communicated with the first sealing cylinder. The air supply member 113 includes a second sealing cylinder, a second push rod and a second spring. The second sealing cylinder is fixed on the two connecting seats 112. The second push rod is movably inserted into the second sealing cylinder. One end of the second push rod extends to the outside of the second sealing cylinder and is arranged opposite to the eccentric wheel 111. The second sealing cylinder and the second push rod are connected by the second spring. The outer surface of the second push rod is in mutual contact with the inner surface of the second sealing cylinder;

[0059] When the rotating shaft 3 rotates in the reverse direction, the push block 103 on the rotating shaft 3 can push the blocking block 104 in the rotating cylinder 102, so that the rotating cylinder 102 rotates accordingly. When the rotating cylinder 102 rotates, it can drive the first shaft body 105 thereon to rotate. When the first shaft body 105 rotates, it can drive the second shaft body 106 to rotate through the meshing of the second gear 107 and the third gear 108. When the second shaft body 106 rotates, it can drive the eccentric wheel 111 to rotate. When the eccentric wheel 111 rotates, it will continuously squeeze the second push rod. When the eccentric wheel 111 squeezes the second push rod, the second push rod can move, and push the gas in the second sealing cylinder into the first sealing cylinder through the connecting pipe 114. When the gas enters the first sealing cylinder, the gas can push the first push rod to move. When the eccentric wheel 111 is separated from the second push rod, the second push rod will reset under the elastic force of the second spring and draw out the gas in the first sealing cylinder through the connecting pipe 114. When the gas in the first sealing cylinder is drawn out, the first push rod will reset under the elastic force of the first spring. Based on the above process, during the rotation of the eccentric wheel 111, the first push rod will continuously move up and down. When the first push rod moves up, the first push rod will push the inclined surface on the fixed block 95, so that the fixed block 95 drives the photovoltaic panel mounting frame 4 to move. When the first push rod moves down, the first push rod no longer exerts a thrust on the fixed block 95. At this time, the photovoltaic panel mounting frame 4 will reset under the action of the pulling rope 91 and the counterweight 93. This makes the photovoltaic panel generate a synchronous vibration effect during the rotation. When the photovoltaic panel vibrates, the snow covering the surface of the photovoltaic panel will be more likely to slide off the photovoltaic panel;

[0060] It should be noted that when the photovoltaic panel rotates from an inclined state to a horizontal state, that is, when the rotating shaft 3 rotates forward, the pushing block 103 on the rotating shaft 3 will move away from the blocking block 104. At this time, the pushing block 103 cannot drive the rotating cylinder 102 to rotate through the blocking block 104, and the vibration action of the photovoltaic panel will not occur. Only when the photovoltaic panel rotates in the reverse direction, that is, when the inclination angle of the photovoltaic panel increases, can the rotating shaft 3 drive the rotating cylinder 102 to rotate, and the photovoltaic panel will perform a vibration action. This special structural design enables the photovoltaic panel to vibrate only when removing snow while inclined, and will not vibrate when sheltering from the wind in the horizontal state;

[0061] In addition, the transmission ratio of the second gear 107 to the third gear 108 is less than 1. Under the meshing action of the second gear 107 and the third gear 108, even if the rotation angles of the rotating shaft 3 and the rotating cylinder 102 are limited, the eccentric wheel 111 can rotate several circles, which enables the photovoltaic panel mounting frame 4 to vibrate for a period of time, so as to ensure the cleaning effect of the snow on the surface area of the photovoltaic panel.
