[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] This invention provides a tracking photovoltaic mounting system, such as... Figure 1 and Figure 4 As shown, it includes: a photovoltaic module, which includes: a side frame 5, an inner strip 6, and a photovoltaic panel 7; two side frames 5 are arranged opposite each other, and the side frames 5 are located on top of the frame 1. The inner strip 6 is fixed to the bottom of the inner side of the side frame 5, and the photovoltaic panel 7 is placed on top of the two inner strips 6 respectively. At this time, the side of the photovoltaic panel 7 is in contact with the inner side wall of the side frame 5. A screw 501 is screwed into the side of the side frame 5, and the inner end of the screw 501 is in contact with the side of the photovoltaic panel 7 to limit the photovoltaic panel 7 between the two side frames 5. The bottom of the inner strip 6 is limited to the top of the frame 1 by a connecting component. The frame 1 is located at the bottom of the photovoltaic module.

[0019] Specifically, push the side frame 5, and the side frame 5 slides on the top of the frame 1 using the connecting parts until the distance between the two side frames 5 is greater than the width of the photovoltaic panel 7. Lock the side frame 5 using the connecting parts, and place the photovoltaic panel 7 on the inner side of the two side frames 5. The side frame 5 supports the photovoltaic panel 7 using the connecting parts and the inner strip 6. At this time, screws 501 are inserted through the side of the side frame 5. By rotating, the inner end of the screw 501 is aligned with the side of the photovoltaic panel 7. Multiple screws 501 are used to lock the photovoltaic panel 7 between the two side frames 5.

[0020] In this embodiment, the connecting component is used to easily lock the photovoltaic module at the top of the frame 1, and the two side frames 5 cooperate with the connecting component to clamp photovoltaic panels 7 of different widths, so that the two side frames 5 can be adapted to photovoltaic panels 7 of different widths.

[0021] To deflect the frame 1 and the photovoltaic modules, a deflection device is used to deflect the photovoltaic modules. Figures 1 to 4 In the process, the deflection assembly includes: a collar 2, a slider 3, and a first elastic element 4, wherein the first elastic element 4 is configured as a spring sheet; the collar 2 is sleeved on the end of the frame 1, and the bottom of the collar 2 is supported by a support column, the bottom end of which is installed on the ground; the inner sidewall of the collar 2 is provided with an arc groove 201, and an arc strip 202 is built inside the arc groove 201; at this time, the bottom end of the slider 3 is inserted into the arc groove 201, and an inner groove 301 is built inside the slider 3; the slider 3 is sleeved on the surface of the arc strip 202 by utilizing the inner groove 301.

[0022] The driving component is a cylinder, and the bottom end of the driving component is hinged to the middle of the support column. A bottom rod 502 is fixed to the bottom of the inner side wall of the side frame 5, and the output end of the driving component is sleeved on the surface of the bottom rod 502.

[0023] Specifically, when the drive unit is activated, the output end of the drive unit pushes the front part of the side frame 5 upward using the base rod 502. The side frame 5 uses the connecting component to make the frame 1 rotate clockwise inside the collar 2. The frame 1 makes the bottom end of the slider 3 move inside the arc groove 201. At this time, the slider 3 moves on the surface of the arc bar 202 using the inner groove 301. The rear end of the side frame 5 moves downward. At this time, the photovoltaic module shifts backward as a whole. When the output end of the drive unit pushes the rear part of the side frame 5 upward using the base rod 502, the side frame 5 uses the connecting component to make the frame 1 rotate counterclockwise inside the collar 2. The front end of the side frame 5 moves downward. At this time, the photovoltaic module shifts forward as a whole.

[0024] When a bottom groove 203 corresponding to the slider 3 is provided at the center of the bottom of the arc groove 201, and the bottom end of the slider 3 is inside the bottom groove 203, the top surface of the arc strip 202 is in contact with the top surface of the inner side of the inner groove 301, and the bottom end of the slider 3 is inside the arc groove 201, the bottom surface of the arc strip 202 is in contact with the bottom surface of the inner side of the inner groove 301.

[0025] In this embodiment, the photovoltaic module is bidirectionally deflected by the power of the driving component, and the arc strip 202 and the slide bar 3 limit the frame 1, so that the frame 1 is stably deflected inside the collar 2. The bidirectionally deflected photovoltaic module allows the photovoltaic panel 7 to track the sunlight, which facilitates the photovoltaic module to generate photovoltaic power.

[0026] To limit the frame 1, the first elastic element 4 is used to allow the bottom end of the slider 3 to be inserted into the bottom groove 203. Figure 2 and Figure 3 In the middle, a semi-circular plate 15 is fixed at the bottom of the frame 1. A notch 16 corresponding to the top of the slide bar 3 is provided on the bottom of the inner side of the semi-circular plate 15. A horizontal plate 17 is provided inside the notch 16. Vertical grooves corresponding to the horizontal plate 17 are provided on both sides of the notch 16. The first elastic member 4 is located inside the vertical groove, and the elastic force of the first elastic member 4 makes the bottom surface of the horizontal plate 17 fit against the top surface of the slide bar 3.

[0027] Specifically, when the photovoltaic module causes the frame 1 to rotate, the semi-circular plate 15 at the bottom of the frame 1 rotates inside the collar 2. Since the notch 16 on the inner side of the semi-circular plate 15 is engaged with the top of the slide bar 3, the rotating semi-circular plate 15 uses the notch 16 to make the bottom end of the slide bar 3 slide out from the bottom groove 203. At this time, the top end of the slide bar 3 moves upward inside the notch 16. The upward movement of the slide bar 3 causes the horizontal plate 17 to press the first elastic member 4 inside the vertical groove. The elastic force of the first elastic member 4 makes the bottom end of the slide bar 3 fit with the bottom surface of the bottom groove 203 and the inner bottom surface of the arc groove 201.

[0028] In this embodiment, the sliding bar 3 cooperates with the arc-shaped bar 202 to enable the frame 1 to rotate stably inside the collar 2. When the bottom end of the sliding bar 3 is inside the bottom groove 203, the elastic force of the first elastic element 4 causes the bottom surface of the horizontal plate 17 to press against the top surface of the sliding bar 3. The elastic force of the first elastic element 4 makes the sliding bar 3 vertically set at the bottom of the frame 1. The elastic force of the first elastic element 4 keeps the frame 1 and the photovoltaic module in a horizontal state, avoiding damage to the photovoltaic module due to excessive external wind force.

[0029] To limit the side frame 5 at the top of the frame 1, the side frame 5 is moved using a connecting component. Figure 1 , Figure 4 and Figure 5 In the process, the connecting components include: a sliding sleeve 8, a sleeve frame 9, a screw 10, an insert rod 11, and a pressing part; the top of the sliding sleeve 8 is provided with a sliding head, and the diameter of the sliding head is larger than the width of the slide groove 101. The bottom surface of the sliding head is in contact with the top surface of the frame 1. The sliding sleeve 8 is vertically inserted into the slide groove 101 at the top of the frame 1. A frame plate 801 is fixed to the side of the sliding sleeve 8. The inner strip 6 is placed on the top surface of the frame plate 801, and the frame plate 801 is connected to the inner strip 6 by bolts. The sleeve frame 9... Located at the bottom of the sliding sleeve 8, a screw 10 is vertically inserted into the center of the sliding sleeve 8, and the sleeve frame 9 is spirally sleeved on the surface of the screw 10. The bottom end of the screw 10 is in contact with the inner bottom surface of the frame 1. An insert rod 11 is fixed on the bottom surface of the sliding sleeve 8, which passes through the sleeve frame 9, so that the sleeve frame 9 can move up and down on the surface of the screw 10. Side edges 901 are provided on both sides of the sleeve frame 9, and the pressing part is installed on the side edges 901, so that the sliding sleeve 8 is confined inside the sliding groove 101 of the frame 1.

[0030] The extrusion section includes a vertical rod 12, a second elastic element 13, and a baffle 14. The second elastic element 13 is configured as a spring. The vertical rod 12 extends vertically through the side 901. A circular plate is fixed to the bottom end of the vertical rod 12, and the top surface of the circular plate is flush with the bottom end of the insertion rod 11. A baffle 14 is fixed to the top of the vertical rod 12. The second elastic element 13 is sleeved on the surface of the vertical rod 12. The top end of the second elastic element 13 is connected to the bottom surface of the baffle 14, and the bottom end of the second elastic element 13 is connected to the top surface of the side 901. The elastic force of the second elastic element 13 causes the top end of the vertical rod 12 to fit against the inner bottom surface of the frame 1.

[0031] Specifically, the sliding sleeve 8 is pushed, and the sliding head of the sliding sleeve 8 moves on the top surface of the frame 1. At this time, the sliding sleeve 8 moves inside the sliding groove 101. The sliding sleeve 8 uses the insert rod 11 to make the sleeve 9 move inside the frame 1. The sleeve 9 makes the top of the vertical rod 12 on the side 901 slide on the inner bottom surface of the frame 1 until the sliding sleeve 8 moves to the appropriate position. Then, the screw 10 is rotated. Since the sleeve 9 is spirally sleeved on the surface of the screw 10, the rotating screw 10 makes the sleeve 9 move upward. At this time, the frame 1 cooperates to limit the vertical rod 12. The sleeve 9 makes the side 901 move up on the surface of the vertical rod 12. The upward side 901 and the baffle 14 press the second elastic member 13. The elastic force of the second elastic member 13 makes the top of the vertical rod 12 tightly press against the inner top surface of the frame 1. The two vertical rods 12 cooperate with the frame 1 to lock the sliding sleeve 8, which facilitates the limitation of the sliding sleeve 8.

[0032] At this point, the side frame 5 is placed on top of the frame 1, and the bottom surface of the inner strip 6 on the inner side of the side frame 5 is attached to the top surface of the frame plate 801. The frame plate 801 is connected to the inner strip 6 with bolts to complete the limitation of the side frame 5.

[0033] In this embodiment, the rotating screw 10 causes the top of the vertical rod 12 to press against the inner top surface of the frame 1. The two vertical rods 12 cooperate with the frame 1 to lock the sliding sleeve 8, which facilitates the definition of the side frame 5 at the top of the frame 1 according to the width of the photovoltaic panel 7.

[0034] Working principle of this invention: Reference Figures 1 to 6 As shown, when the sliding sleeve 8 is pushed, the sliding head of the sliding sleeve 8 moves on the top surface of the frame 1. At this time, the sliding sleeve 8 moves inside the sliding groove 101. The sliding sleeve 8 uses the insert rod 11 to make the sleeve 9 move inside the frame 1. The sleeve 9 makes the top of the vertical rod 12 on the side 901 slide on the bottom inner surface of the frame 1 until the sliding sleeve 8 moves to the appropriate position. Then, the screw 10 is rotated. Since the sleeve 9 is spirally sleeved on the surface of the screw 10, the rotating screw 10 makes the sleeve 9 move upward. At this time, the frame 1 cooperates to limit the vertical rod 12. The sleeve 9 makes the side 901 move up on the surface of the vertical rod 12. The upward side 901 and the baffle 14 press the second elastic member 13. The elastic force of the second elastic member 13 makes the top of the vertical rod 12 tightly press against the top inner surface of the frame 1. The two vertical rods 12 cooperate with the frame 1 to lock the sliding sleeve 8, which facilitates the limitation of the sliding sleeve 8.

[0035] At this point, the side frame 5 is placed on top of the frame 1, and the bottom surface of the inner strip 6 on the inner side of the side frame 5 is attached to the top surface of the frame plate 801. The frame plate 801 is connected to the inner strip 6 with bolts to complete the limitation of the side frame 5.

[0036] When the sliding sleeve 8 moves the side frame 5, until the distance between the two side frames 5 is greater than the width of the photovoltaic panel 7, the side frame 5 is locked by the connecting parts, and the photovoltaic panel 7 is placed inside the two side frames 5. The side frame 5 supports the photovoltaic panel 7 by the connecting parts and the inner strip 6. At this time, the screw 501 passes through the side of the side frame 5. By rotating, the inner end of the screw 501 is aligned with the side of the photovoltaic panel 7. The photovoltaic panel 7 is locked between the two side frames 5 by the use of multiple screws 501.

[0037] When the drive unit is activated, the output end of the drive unit pushes the front part of the side frame 5 upward using the bottom rod 502. The side frame 5 uses the connecting component to make the frame 1 rotate clockwise inside the collar 2. The semi-circular plate 15 at the bottom of the frame 1 rotates inside the collar 2. Since the notch 16 on the inner side of the semi-circular plate 15 is engaged with the top of the slide bar 3, the rotating semi-circular plate 15 uses the notch 16 to make the bottom end of the slide bar 3 slide out from inside the bottom groove 203. At this time, the top end of the slide bar 3 moves upward inside the notch 16. The upward movement of the slide bar 3 causes the horizontal plate 17 to press the first elastic element 4 inside the vertical groove. The elastic force of the first elastic element 4 makes the bottom end of the slide bar 3 fit against the bottom surface of the bottom groove 203 and the inner bottom surface of the arc groove 201.

[0038] The rotating frame 1 causes the bottom end of the slider 3 to move inside the arc groove 201. At this time, the slider 3 moves on the surface of the arc bar 202 using the inner groove 301, and the rear end of the side frame 5 moves down. At this time, the photovoltaic module shifts backward as a whole. The output end of the drive component pushes the rear part of the side frame 5 upward using the bottom rod 502. The side frame 5 uses the connecting component to make the frame 1 rotate counterclockwise inside the collar 2, and the front end of the side frame 5 moves down. At this time, the photovoltaic module shifts forward as a whole.

[0039] The photovoltaic module is bidirectionally deflected by the power of the driving component, and the arc strip 202 and the slider 3 limit the frame 1, so that the frame 1 deflects stably inside the collar 2. The bidirectionally deflected photovoltaic module allows the photovoltaic panel 7 to track the sunlight, which facilitates the photovoltaic module to generate photovoltaic power.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
