DETAILED DESCRIPTION

[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0017] See also Figure 1-7 As shown in the figure, the reference specification provided in this embodiment Figure 1-7 , a photovoltaic assembly support that is easy to maintain according to an embodiment of the present invention, such as Figure 1-2 As shown, it includes a photovoltaic support body 1; an extension mechanism 2 is fixedly installed at the bottom of the photovoltaic support body 1.

[0018] Combination Figure 5-6As shown, the photovoltaic bracket body 1 includes an inclined brace balance frame 102 arranged in an inclined state and a balance base 101 fixedly connected to the inclined brace balance frame 102. A plurality of photovoltaic mounting panels 104 parallel to the inclined brace balance frame 102 are arranged on the top of the inclined brace balance frame 102. The surface of the photovoltaic mounting panel 104 can be used to fix and install a plurality of photovoltaic panels. The sides of the plurality of photovoltaic mounting panels 104 are fixedly installed with magnetic side strips 103. The magnetic side strips 103 can attract each other, and elastic pads are arranged at the end points of the inclined brace balance frame 102 and at the edge of the positioning plate 21. In the initial state, the magnetic side strips 103 are magnetically connected to each other. The photovoltaic mounting panels 104 and the photovoltaic panels in the frame are connected to each other to form an integral photovoltaic panel, and the ends of the magnetic side strips 103 are attached to the end points of the diagonal brace balance frame 102; and the extension mechanism 2 includes a positioning plate 21 fixedly installed at the bottom of the diagonal brace balance frame 102, and a plurality of first limiting grooves 22 are provided inside the positioning plate 21. Preferably, the number of the first limiting grooves 22 can be four, and the four first limiting grooves 22 are respectively arranged in the four directions of up, down, left and right of the positioning plate 21, and the inner cavities of the plurality of first limiting grooves 22 are slidably installed with first supporting rods 23, and the positioning plate 21 has a surface The surface is also provided with a second limiting groove 24, which is specifically provided at a position on the positioning plate 21 corresponding to the first limiting groove 22. A plurality of third limiting grooves 25 arranged in a through shape are provided inside the diagonal brace balance frame 102. The first limiting groove 22, the first limiting groove 22 and the third limiting groove 25 correspond one to one. The third limiting groove 25 and the inner cavity of the second limiting groove 24 provided on the top of the positioning plate 21 are both slidably installed with a first guide limiting rod 26 fixedly connected to the first supporting rod 23, and the first guide limiting rod 26 extends out of the top of the third limiting groove 25. A positioning tray 27 is fixedly installed, and a plurality of positioning trays 27 are respectively fixedly connected to the back sides of multiple photovoltaic mounting panels 104; when the first supporting rod 23 is driven to move, the positioning tray 27 can drive the multiple photovoltaic mounting panels 104 and the multiple photovoltaic panels to be split into multiple small pieces from a whole. Under normal circumstances, the first guide limit rod 26 is located on the side of the third limit groove 25 close to the center point of the diagonal support balance frame 102. At this time, the multiple first supporting rods 23 are completely extended into the inner cavity of the first limit groove 22, and the distances between the multiple positioning trays 27 are close to each other. At this time, the multiple photovoltaic mounting panels 104 and the multiple photovoltaic panels are abutted against each other to form an integral photovoltaic panel.

[0019] It can be understood that when encountering extremely windy weather, by making the multiple first supporting rods 23 synchronously translate and slide out of the inner cavity of the first limiting groove 22, the first guide limiting rod 26 and the positioning tray 27 can be gradually moved inside the third limiting groove 25 in the direction away from the center of the diagonal support balance frame 102, so that the distance between the multiple positioning trays 27 can be gradually increased, thereby driving the photovoltaic mounting panels 104 and the magnetic edge strips 103 to extend in all directions together, and finally the multiple photovoltaic mounting panels 104 and the multiple photovoltaic panels are split from the whole into multiple small pieces, and gaps are also generated between the small pieces. In this process, not only the area of ​​each small piece is reduced, but the wind force it receives is also reduced compared to the whole photovoltaic panel, and the wind can pass through the gap, reducing the overall wind resistance, thereby reducing the impact of the wind on the photovoltaic panel. In addition, after the splitting, the stress distribution of each small piece is relatively independent, avoiding the concentration of stress on the entire photovoltaic panel and reducing the possibility of cracks. At the same time, since the photovoltaic mounting panels 104 and the magnetic edge strips 103 are together After extending to all sides, the magnetic edge strip 103 no longer contacts the end point of the diagonal brace balance frame 102. At this time, the middle part of the photovoltaic mounting plate 104 contacts the elastic pad at the end point of the diagonal brace balance frame 102 or the edge of the positioning plate 21, so that the photovoltaic mounting plate 104 and the photovoltaic panel installed on it can be deflected and adjusted at a small angle according to the wind direction, thereby reducing its windward area, further reducing the overall wind resistance, reducing the direct impact of wind on the photovoltaic panel, avoiding stress concentration caused by fixed angles, thereby reducing the risk of cracks and reducing maintenance. Cost; when the weather returns to normal, the multiple first supporting rods 23 can synchronously perform reverse translational movement, thereby driving the positioning tray 27, the photovoltaic mounting panel 104 and the magnetic edge strip 103 to synchronously approach the center of the diagonal support balance frame 102 until the magnetic edge strip 103 is re-attached to the end point of the diagonal support balance frame 102, and the multiple photovoltaic mounting panels 104 and the multiple photovoltaic panels are abutted against each other to form an integral photovoltaic panel, and the magnetic edge strips 103 are magnetically connected to each other to form a frame, thereby improving the overall stability.

[0020] Furthermore, combined with Figure 6 As shown, the positioning plate 21 and the diagonal brace balance frame 102 are arranged in parallel with each other, and the positioning plate 21 is arranged at the vertical center of the photovoltaic mounting panel 104. The purpose of such arrangement is that when the multiple first supporting rods 23 and the corresponding positioning trays 27 arranged inside the positioning plate 21 support the back of the photovoltaic mounting panel 104, the photovoltaic mounting panel 104 is subjected to more uniform force and is supported more stably.

[0021] Furthermore, combined with Figure 6-7As shown, a limit turntable 28 is rotatably installed at the bottom of the positioning plate 21, and a plurality of fourth limit slots 29 arranged in a through shape are opened inside the limit turntable 28. The inner cavities of the plurality of fourth limit slots 29 are slidably installed with a second guide limit rod 210 fixedly connected to the first supporting rod 23. In actual use, by rotating the limit turntable 28 and making the second guide limit rod 210 slide and displace in the inner cavity of the fourth limit slot 29, the first supporting rod 23 can be synchronously translated inside the first limit slot 22, so as to adjust the displacement of the plurality of positioning trays 27.

[0022] Furthermore, at the same time, refer to Figure 7 and Figure 5 As shown, the bottom of the extension mechanism 2 is fixedly connected to an auxiliary adjustment mechanism 3, and the auxiliary adjustment mechanism 3 includes a threaded screw 31 fixedly installed on the bottom of the limit turntable 28, and an external bevel gear 33 is fixedly installed on the bottom of the threaded screw 31. An electric internal bevel gear 34 meshing with the external bevel gear 33 is rotatably installed on the top of the balancing base 101, and the outer walls of the threaded screw 31 and the external bevel gear 33 are rotatably installed with a second supporting rod 32 fixedly connected to the balancing base 101.

[0023] It can be understood that in actual use, by starting the electric inner bevel gear 34 to rotate, the outer bevel gear 33 can be driven to rotate the threaded screw 31, and then the limit turntable 28 can be synchronously driven to rotate, so that when the second guide limit rod 210 slides and displaces in the inner cavity of the fourth limit groove 29, the first supporting rod 23 can be synchronously translated inside the first limit groove 22, so as to adjust the displacement of multiple positioning trays 27.

[0024] Further preferably, a shielding mechanism 5 is also fixedly installed on the top of the photovoltaic bracket body 1; the shielding mechanism 5 includes two guide sliding rods 51 rotatably installed on the top of the magnetic edge strip 103, and one end of the guide sliding rod 51 is fixedly connected to a guide threaded rod 52 rotatably connected to the magnetic edge strip 103, and the two guide sliding rods 51 and the two guide threaded rods 52 are arranged in opposite states, wherein the two opposite magnetic edge strips 103 are fixedly installed with elastic positioning strips 53, and the guide threaded rods 52 are meshed with elastic guide strips 54 slidably connected to the guide sliding rods 51, and an elastic protective net 55 is fixedly installed between the elastic positioning strip 53 and the elastic guide strip 54.

[0025] Specifically, refer to Figure 3-4As shown, a shielding mechanism 5 is fixedly installed on the top of the photovoltaic bracket body 1, and the shielding mechanism 5 includes two guide sliding rods 51 rotatably installed on the top of the magnetic side strip 103, and one end of the two guide sliding rods 51 is fixedly connected to a guide threaded rod 52 rotatably connected to the magnetic side strip 103; wherein, the two guide sliding rods 51 and the two guide threaded rods 52 are arranged in opposite states at the installation positions on the top of the magnetic side strip 103, wherein elastic positioning strips 53 are fixedly installed on the two opposite magnetic side strips 103, and the outer walls of the two guide threaded rods 52 are meshed with elastic guide strips 54 slidably connected to the guide sliding rods 51, and an elastic protective net 55 is fixedly installed between the elastic positioning strip 53 and the elastic guide strip 54.

[0026] It can be understood that when the guide sliding support rod 51 and the guide threaded rod 52 fixedly connected together rotate synchronously, the elastic guide bar 54 can be translated along the outer walls of the two. Under normal conditions, the elastic guide bar 54 is close to the elastic positioning bar 53, and the elastic protection net 55 is in a contracted and folded state on the magnetic edge strip 103. With the displacement of the elastic guide bar 54, the stretched elastic protection net 55 is gradually stretched out until the two elastic guide bars 54 set on the top of the photovoltaic mounting board 104 abut against each other in the middle position of the photovoltaic panel, and the elastic protection net 55 covers and blocks the photovoltaic mounting board 104 and the top of the photovoltaic panel, so that the surface of the photovoltaic panel can be protected in the state of strong winds, and large debris can be blocked on the outside of the elastic protection net 55 without affecting the wind passing through the elastic protection net 55, thereby reducing the coverage of debris and reducing the impact of debris on the photovoltaic panel; after the weather returns to normal, the two elastic protection nets 55 can be retracted to put the photovoltaic panel on the photovoltaic mounting board 104 into working state again, and the frequency of cleaning and maintenance is also reduced.

[0027] Further preferably, the auxiliary adjustment mechanism 3 is provided with a pressing mechanism 4, and the pressing mechanism 4 includes horizontal telescopic limit rods 42 installed on both sides of the photovoltaic mounting panel 104, and a gear ring 56 is fixedly installed at the connection between the guide sliding support rod 51 and the guide threaded rod 52, and a guide rack 57 meshing with the gear ring 56 is fixedly installed on the horizontal telescopic limit rod 42, and an internal threaded connecting sleeve 41 is also meshed on the threaded screw 31, and the internal threaded connecting sleeve 41 is fixedly connected to the horizontal telescopic limit rod 42, and a pressing block 43 is fixedly installed on the top of the horizontal telescopic limit rod 42.

[0028] Specifically, combined Figure 3As shown, the outer wall of the auxiliary adjustment mechanism 3 is provided with a holding mechanism 4, and the holding mechanism 4 includes a horizontal telescopic limit rod 42 installed on both sides of the photovoltaic installation panel 104; at the same time, a gear ring 56 is fixedly installed on the outside of the connection between the guide sliding support rod 51 and the guide threaded rod 52, and a guide rack 57 meshing with the gear ring 56 is fixedly installed on the outer wall of the horizontal telescopic limit rod 42. In actual use, as the horizontal telescopic limit rod 42 moves up and down, the guide rack 57 can be synchronously displaced up and down, and then the gear ring 56 meshing with it can be driven to rotate, so that the guide sliding support rod 51 and the guide threaded rod 52 fixedly connected to each other can be synchronously rotated; at the same time, the outer wall of the threaded screw 31 is meshed with an internal threaded connection sleeve 41 fixedly connected to the horizontal telescopic limit rod 42. When the threaded screw 31 rotates, the internal threaded connection sleeve 41 is also synchronously driven to drive the horizontal telescopic limit rod 42 to move up and down on its outer wall for adjustment; the tops of the two horizontal telescopic limit rods 42 are fixedly installed with holding blocks 43.

[0029] It can be understood that in specific implementation, when encountering extremely windy weather, by starting the electric inner bevel gear 34 to rotate, the outer bevel gear 33 can be driven to rotate the threaded screw 31. On the one hand, the first supporting rod 23 and the positioning tray 27 can be slidably adjusted to translate synchronously, and the positioning tray 27 gradually moves away from the center of the device, thereby reducing the internal stress by reducing the force area, reducing wind resistance and optimizing the force, thereby effectively reducing the risk of cracks in the photovoltaic panel; on the other hand, it will also synchronously drive the two horizontal telescopic limit rods 42 to move downward, and then through the gear ring 56 and the guide The cooperation of the rack 57 causes the guide sliding support rod 51 and the guide threaded rod 52 to rotate synchronously, and finally causes the two elastic guide strips 54 to abut against each other in the middle position of the photovoltaic panel, and the elastic protective net 55 covers and shields the photovoltaic mounting plate 104 and the top of the photovoltaic panel; at the same time, the two horizontal telescopic limit rods 42 move downward, and also drive the holding block 43 to move downward. When the two elastic guide strips 54 abut against each other, the two corresponding holding blocks 43 can be pressed at the connection between the two elastic guide strips 54, thereby greatly improving the stability of the shielding mechanism 5 and preventing the shielding mechanism 5 from being damaged by strong winds.

[0030] Further preferably, limiting collars 44 are fixedly installed on both sides of the magnetic edge strip 103 , and the horizontal telescopic limiting rod 42 is slidably installed in the inner cavity of the limiting collar 44 .

[0031] Specifically, referring to Figure 3 As shown, the two horizontal telescopic limit rods 42 are arranged at the vertical center of the photovoltaic mounting panel 104, and the two horizontal telescopic limit rods 42 are arranged symmetrically with respect to the vertical center line of the magnetic edge strip 103. The purpose of such arrangement is to keep the horizontal telescopic limit rod 42 auxiliaryly limited when moving up and down, thereby maintaining the movement stability of the horizontal telescopic limit rod 42. Figure 4 As shown, both sides of the magnetic edge strip 103 are fixedly installed with limiting collars 44 , and the horizontal telescopic limiting rod 42 is slidably installed in the inner cavity of the limiting collar 44 .

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
