Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic modules and relates to a windproof suspension-cable photovoltaic assembly. Background Art

[0002] Cable-suspended photovoltaic modules are mainly composed of support frames, steel cables, bases, and solar panels. During assembly, the support frames are fixed above rivers, ponds, or other environments with complex terrain. The steel cables span the occupied site, and then the solar panels are installed on the steel cables. The solar panels are fixed to the steel cables through the snap-on base to complete the installation, which improves the adaptability, economy, and site utilization efficiency of the entire photovoltaic system.

[0004] In the above patent, all photovoltaic panels are interconnected. When the wind is too strong, in order to reduce wind resistance, the photovoltaic modules are gathered together to form an M-shaped group. In this way, the wind-exposed area is reduced to provide a certain degree of protection for the photovoltaic modules. However, after being gathered together, the upper ends of the photovoltaic panels are still connected. The structure of the photovoltaic panels as a whole is connected, and the wind-exposed area is increased. When the wind blows, the wind blows through the connection between the photovoltaic modules. Due to the large wind-exposed area, a large wind resistance will be generated, and the wind pressure will also be greater, which can easily damage or blow off the photovoltaic modules.

DETAILED DESCRIPTION

[0030] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0031] A windproof suspension photovoltaic module, such as Figure 1-Figure 6 As shown, it includes a suspension cable 1, an upper mounting sleeve 2, a photovoltaic panel 3, a connecting rod 4, a lifting mechanism and a mounting mechanism. The left parts of the front and rear sides of the bottom of the photovoltaic panel 3 are hingedly connected with the upper mounting sleeve 2. The photovoltaic panel 3 is arranged on the suspension cable 1 through the upper mounting sleeve 2. The left and right sides of the two upper mounting sleeves 2 are connected with the connecting rod 4. The upper mounting sleeve 2 is provided with a mounting mechanism and a lifting mechanism for lifting the photovoltaic panel 3.

[0032] like Figure 2-Figure 4As shown, the lifting mechanism includes a connecting frame 51, a driving motor 52, a screw 53, a swing rod 54, a transmission assembly, a sliding block 55 and a slider 56. The two upper mounting sleeves 2 are connected to the connecting frame 51, and the driving motor 52 is installed on the right side of the connecting frame 51. The output shaft of the driving motor 52 is connected to the screw 53, and the screw 53 is rotatably connected to the connecting frame 51. The sliding block 55 is slidably connected to the connecting frame 51, and the sliding block 55 is threadedly matched with the screw 53 so that the rotation of the screw 53 can drive the sliding block 55 to move left and right. Slide blocks 56 are slidably connected to the front and rear sides of the bottom of the photovoltaic panel 3, and a swing rod 54 is hingedly connected between the slider 56 and the sliding block 55. A transmission assembly is provided on the swing rod 54 and the connecting frame 51, and the transmission assembly is used to drive the swing rod 54 to swing upward. The movement of the sliding block 55 can squeeze the slider 56 upward through the swing rod 54, thereby pushing the photovoltaic panel 3 to swing.

[0033] like Figure 4 As shown, the transmission assembly includes a gear 541 and a rack 542. The gear 541 is connected to the swing rod 54, and the rack 542 is connected to the connecting frame 51. The rack 542 is meshed with the gear 541, so that when the sliding block 55 drives the swing rod 54 to move, the meshing between the rack 542 and the gear 541 allows the swing rod 54 to swing upward, thereby lifting the photovoltaic panel 3 upward through the slider 56.

[0034] like Figure 5 and Figure 6 As shown, the mounting mechanism includes a lower mounting sleeve 61 and a locking frame 62. The two upper mounting sleeves 2 are rotatably connected with the lower mounting sleeves 61. The lower mounting sleeves 61 and the upper mounting sleeves 2 are provided with locking holes. The locking frame 62 can be inserted into the locking holes of the upper mounting sleeve 2 and the lower mounting sleeve 61. The lower mounting sleeve 61 and the upper mounting sleeve 2 can be mounted on the suspension cable 1, and then the locking frame 62 is inserted into the locking hole positions of the upper mounting sleeve 2 and the lower mounting sleeve 61, so as to fix the photovoltaic panel 3.

[0035] When the photovoltaic module needs to be used, the photovoltaic module can be used. During the installation process, the locking frame 62 is first removed, and then the lower mounting sleeve 61 is controlled to swing, so that the lower mounting sleeve 61 and the upper mounting sleeve 2 are separated, and then the lower mounting sleeve 61 and the upper mounting sleeve 2 are mounted on the suspension cable 1. After the mounting is completed, the lower mounting sleeve 61 is pulled to reset, and then the locking frame 62 is inserted into the lock hole position of the lower mounting sleeve 61 and the upper mounting sleeve 2, so as to complete the installation of the photovoltaic panel 3. During use, if there is frontal wind blowing from top to bottom, the driving motor 52 can be controlled to drive the screw rod 53 to rotate, and the rotation of the screw 53 drives the sliding block 55 to move to the left. When the sliding block 55 moves, it can drive the swing rod 54 to swing upward through the gear 541 and the rack 542, thereby squeezing the slider 56 to move upward to lift the photovoltaic panel 3, so that the state of the photovoltaic panel 3 is as follows: Figure 2 As shown, the wind-exposed area of ​​the photovoltaic panel 3 is reduced, thereby reducing the wind exposure and avoiding the vibration of the suspension cable 1. When the photovoltaic panel 3 is erected, each photovoltaic panel 3 is erected one by one, and the overall area is smaller, which further reduces the wind-exposed area. When the photovoltaic panel is erected, refer to Figure 2 The photovoltaic panel 3 can be supported by forming a triangular support structure through the connection 51, the swing rod 52 and the photovoltaic panel 3, thereby ensuring the stability of the photovoltaic panel 3 when it is erected and preventing the photovoltaic panel 3 from being affected by wind and causing position displacement.

[0036] like Figure 5 and Figure 6 As shown, a rotating sleeve 71 is also included. The two connecting rods 4 are rotatably connected to the rotating sleeve 71. The left and right sides of the rotating sleeve 71 are provided with limiting protrusions 72. The limiting protrusions 72 on the rotating sleeve 71 abut against the locking frame 62 to prevent the locking frame 62 from moving.

[0037] When installing the locking frame 62, you can first rotate the rotating sleeve 71 so that the limiting protrusion 72 will not block the moving trajectory of the locking frame 62, and then you can install the locking frame 62. After installation, rotate the rotating sleeve 71 again so that the limiting protrusion 72 blocks the locking frame 62, thereby blocking the locking frame 62 and preventing the locking frame 62 from loosening.

[0038] like Figure 7-10As shown, a shielding mechanism is also included, and the shielding mechanism includes a side panel 81, a shielding curtain 82, a rotating shaft 821, a weight 83, an elastic member 84 and a connecting rope 85. The front and rear sides of the top of the photovoltaic panel 3 are connected to the side panels 81, and the left sides of the side panels 81 are rotatably connected with the rotating shaft 821. The shielding curtain 82 is wound on the rotating shaft 821. The front and rear sides of the bottom of the photovoltaic panel 3 are slidably connected with the weight 83, and a connecting rope 85 is connected between the weight 83 and the end of the shielding curtain 82, so that the shielding curtain 82 can be pulled out through the connecting rope 85 when the weight 83 moves. The connecting rope 85 bypasses the side panel 81, thereby guiding the connecting rope 85 through the side panel 81, and an elastic member 84 is connected between the rotating shaft 821 and the side panel 81, and the elastic member 84 is a spiral spring.

[0039] When the photovoltaic panel 3 is erected, the weight 83 will move downward under the action of gravity. When the weight 83 moves downward, it can pull the connecting rope 85 to move. When the connecting rope 85 moves, it can pull out the shielding curtain 82, so that the shielding curtain 82 blocks the photovoltaic panel 3. The rotating shaft 821 rotates when the shielding curtain 82 is pulled out, and the elastic member 84 is also deformed, so that the photovoltaic panel 3 can be blocked when the photovoltaic panel 3 is erected to prevent garbage from being blown onto the photovoltaic panel 3 during wind. After the photovoltaic panel 3 is reset and flattened, the component of the gravity of the weight 83 on the connecting rope 85 becomes smaller, and the force required to pull the weight 83 to move is also reduced. At this time, the reset of the elastic member 84 can drive the rotating shaft 821 to rotate, thereby retracting the shielding curtain 82. When the shielding curtain 82 is retracted, the weight 83 is pulled back to its original position by the connecting rope 85.

[0040] like Fig.11 As shown, it also includes a limit block 9. The left side of the upper mounting sleeve 2 is connected to the limit block 9. When multiple photovoltaic panels 3 are installed on the suspension cable 1, the limit block 9 can separate the upper mounting sleeves 2 on the photovoltaic panels 3 at a certain distance to avoid the photovoltaic panels 3 being too close to each other and affecting the windproof effect when erected.

[0041] like Fig.12 As shown, a scraper plate 10 is also included. The scraper plate 10 is connected to the end of the shielding curtain 82. The scraper plate 10 contacts the photovoltaic panel 3 so that the shielding curtain 82 can drive the scraper plate 10 to move when it is unfolded, so that the scraper plate 10 can scrape off impurities attached to the photovoltaic panel 3.

[0042] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
