DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0018] like Figure 1-2As shown, a solar photovoltaic panel tilt angle automatic adjustment locking mechanism includes a photovoltaic panel 1 and a fixed plate 2 provided at the bottom of the photovoltaic panel 1. The photovoltaic panel 1 is an existing solar photovoltaic panel. The photovoltaic panel plane is fixed to the end surface of the fixed plate 2. Two horizontal bars 3 arranged parallel to each other are provided below the fixed plate 2. The lower side of the fixed plate 2 is rotatably connected to the same end of the two horizontal bars 3. The two horizontal bars 3 are arranged parallel to both sides of the fixed plate 2. The fixed plate 2 can drive the photovoltaic panel 1 to flip up and down relative to one end of the horizontal bar 3 to achieve the tilt of the photovoltaic panel 1 and the change of the tilt angle of the photovoltaic panel 1. The other end of the horizontal bar 3 is provided with a support column 4 arranged upwardly tilted. The fixed plate 2, the horizontal bar 3 and the support column 4 are mutually enclosed to form a triangular support structure for the photovoltaic panel. The movable rod 41 can be elastically moved along the tilting direction of the support column 4, and the movable rod 41 supports the upper side of the fixed plate 2, so that the fixed plate 2 can change the tilt angle as the movable rod 41 moves, thereby realizing the adjustment of the tilt angle of the photovoltaic panel. The support column 4 is tilted so that the angle between the support column 4 and the cross bar 3 is greater than 90 degrees. Therefore, when affected by strong wind, the force direction of the photovoltaic panel 1 and the fixed plate 2 is inconsistent with the movable direction of the movable rod 41. The movement of the movable rod 41 is guided by the tilted support column 4 and the control of the movable rod 41 is increased. The lateral limitation of the movable rod 41 strengthens the structural strength for maintaining the tilt angle of the photovoltaic panel 1, strengthens the self-locking ability of the photovoltaic panel 1 when it is tilted and fixed, and prevents the movable rod 41 from moving when the photovoltaic panel 1 and the fixed panel 2 are blown by strong winds, causing the tilt angle of the photovoltaic panel 1 to change, thereby ensuring full utilization of solar energy. A rotatable winding wheel 31 is provided on the horizontal bar 3, and a first connecting member 32 connected to the side wall of the movable rod 41 is wound around the winding wheel 31. The first connecting member 32 can be made of a steel cable or a chain, etc., which is wound around the side wall of the winding wheel 31. When the winding wheel 31 rotates to release the first connecting member 32, the first connecting member 32 moves with the movement of the movable rod 41 through the elastic movement of the movable rod 41. The movable rod 41 is stretched and maintained in a pulling state. When the winding wheel 31 rotates to rewind the first connecting member 32, the first connecting member 32 pulls the movable rod 41 so that the movable rod 41 overcomes the elasticity and moves. The movement of the movable rod 41 realizes the adjustment of the inclination angle of the fixed plate 2, thereby changing the inclination angle of the photovoltaic panel 1 and maintaining the inclination angle. A strip groove 40 is provided on the side wall of the support column 4 along the inclination direction of the support column 4. The two ends of the movable rod 41 are respectively inserted into the strip groove 40 and slide with the strip groove 40. The movable rod 41 moves along the strip groove 40 to change the inclination angle of the fixed plate 2. The strip groove 40 limits and guides the movement of the movable rod 41 to ensure that the movable rod 41 is stable and reliable when moving.

[0019] like Figure 1-2As shown, a rotatable shaft 33 is provided between the two horizontal bars 3 corresponding to the lower part of the support column 4, and a driving motor 34 coaxially connected to one end of the shaft 33 is provided on the side wall of one of the horizontal bars 3, and the two ends of the winding wheel 31 are coaxially connected to the output shaft of the driving motor 34 and the output shaft of the shaft 33 respectively. The driving motor 34 can drive the winding wheel 31 to rotate, realizing the automatic winding action and automatic release action of the first connecting member 32 to control the movement of the movable rod 41. The setting of the shaft 33 makes the winding wheels of the two horizontal bars 3 31 can rotate synchronously to realize synchronous driving of the two ends of the movable rod 41, ensuring the stability of the movable rod 41 when moving. A slot 35 is provided at the top of the crossbar 3 corresponding to the bottom of the support column 4. The winding wheel 31 is arranged in the slot 35. The slot 35 accommodates and positions the winding wheel 31 and increases the moving space of the first connecting member 32. One end of the first connecting member 32 is wound around the winding wheel 31, and the other end of the first connecting member 32 extends out of the slot 35 and extends along the inclined direction of the support column 4 and is connected to the movable rod 41. The first connecting member The component 32 realizes the movement drive of the movable rod 41 through the control of the winding wheel 31. The support column 4 is provided with a receiving groove 42 for accommodating the first connecting member 32. The receiving groove 42 is provided with a second connecting member 43. The second connecting member 43 can be a steel cable or a chain. A guide wheel 421 is provided at the top of the receiving groove 42. One end of the second connecting member 43 is connected to the movable rod 41. The other end of the second connecting member 43 extends into the receiving groove 42 and is wound around the guide wheel 421. The setting of the guide wheel 421 can change the second connecting member 4 With respect to the direction of the force acting on the movable rod 41, when the movable rod 41 moves, the fixed guide wheel 421 always maintains its guiding effect on the second connecting member 43, thereby ensuring that the second connecting member 43 can always stably pull the movable rod 41. At the same time, when the winding wheel 31 releases the first connecting member 32, the second connecting member 43 can maintain a taut state on the movable rod 41, thereby preventing the movable rod 41 from being easily moved by external forces when the first connecting member 32 is released, thereby enhancing the stability of the movable rod 41 in the fixed position.

[0020] like Figure 2As shown, the second connecting member 43 extends from the guide wheel 421 and is provided with a counterweight 44 at the end. Both sides of the accommodating groove 42 are provided with a limiting slide 422 arranged along the inclined direction of the support column 4. The counterweight 44 slides with the limiting slide 422. The setting of the counterweight 44 can enhance the pulling strength of the second connecting member 43 on the movable rod 41, so as to ensure reliable pulling of the movable rod 41 when the first connecting member 32 is released by the winding wheel 31, so that the movable rod 41 can be stably moved to the specified position. At the same time, after the first connecting member 32 is wound up by the winding wheel 31, the first connecting member 32 is The component 32 and the second connecting component 43 can synchronously apply tensioning force to the two opposite sides of the movable rod 41 to maintain the stability of the movable rod 41. When the winding wheel 31 rotates to reel in or release the movable rod 41, the counterweight component 44 at the end of the second connecting component 43 can slide along the limiting slide 422. The movement of the counterweight component 44 is limited and guided by the limiting slide 422 to ensure the structural stability of the counterweight component 44 and avoid shaking due to external force. At the same time, the setting of the counterweight component 44 can increase the counterweight of the support column 4 and strengthen the supporting stability of the support column 4 and the cross bar 3 for the photovoltaic panel 1.

[0021] like Figure 2-3 As shown, a positioning shaft 21 is provided on the bottom of the lower side of the fixed plate 2 and is passed through the end of the cross bar 3. A movable groove 36 is provided at the end of the cross bar 3. The end of the positioning shaft 21 is located in the movable groove 36. The movable groove 36 is used to position the positioning shaft 21 so that the fixed plate 2 can be stably flipped with the positioning shaft 21 as the rotation center to adjust the inclination angle of the photovoltaic panel 1, and the movable groove 36 can increase the activity space of the movable column 37. The flipping of the movable column 37 makes way for a movable column 37. A movable column 37 rotatably connected to the positioning shaft 21 is provided in the movable groove 36. A limiting cylinder 38 is sleeved on the movable column 37 in the movable groove. The movable column 37 and the limiting cylinder 38 move relative to each other along the axial direction to realize telescopic movement. The end of the limiting cylinder 38 is located in the accommodating groove 42 and is rotatably connected to the end of the movable rod 41. A telescopic spring 381 connected to the end of the movable column 37 is provided in the limiting cylinder 38. The elastic support for the movable rod 41 is increased so that after the first connecting member 32 is released, the movable rod 41 can automatically move by the action of the telescopic spring 381 and adapt to the movement of the movable rod 41 through the telescopic action. At the same time, the end of the movable column 37 is rotatably connected to the cross bar 3, and the end of the limiting cylinder 38 is rotatably connected to the end of the movable rod 41 on the support column 4, which can form a triangular structure between the support column 4 and the cross bar 3 to strengthen the support strength of the photovoltaic panel 1. An axially arranged limiting groove 382 is provided on the inner wall of the limiting cylinder 38, and a limiting block 371 is provided at the end of the movable column 37 to cooperate with the limiting groove 382. The setting of the limiting groove 382 and the limiting block 371 is so as to increase the guiding limit of the movable column 37, strengthen the stability of the movable column 37 when moving in the limiting cylinder 38, and prevent the movable column 37 from falling out of the limiting cylinder 38, thereby strengthening the structural stability.

[0022] like Figure 4 As shown, a fixing piece 411 is provided in the middle of the movable rod 41 for rotationally connecting with the movable rod 41. The fixing piece 411 is sleeved on the movable rod 41 and can rotate relative to the movable rod 41, so that when the movable rod 41 moves, the upper side of the fixed plate 2 can be relatively deflected with the movement of the movable rod 41 to change its own inclination angle. A T-shaped limiting groove 22 is provided in the middle of the fixed plate 2 and is arranged in the inclination direction. A T-shaped limiting block 412 is provided on the fixing piece 411 and is slidably matched with the T-shaped limiting groove 22. The T-shaped limiting groove 22 and the T-shaped limiting block 412 are arranged in cooperation so as to facilitate The movable rod 41 and the fixed plate 2 are connected, and the inclination of the fixed plate 2 is guided and limited by the cooperation of the T-shaped limit groove 22 and the T-shaped limit block 412 to avoid the fixed plate 2 from being offset and increase the positioning effect of the fixed plate 2. At the same time, during the movement of the movable rod 41, the fixed plate 2 tilts accordingly, and the T-shaped limit block 412 can move along the T-shaped limit groove 22. The T-shaped limit groove 22 guides the movement of the T-shaped limit block 412, thereby ensuring that the fixed plate 2 can stably tilt accordingly when the movable rod 41 moves, thereby playing a role in stabilizing the adjustment of the inclination angle of the photovoltaic panel.

[0023] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
