Description

Technical Field

[0001] This invention relates to the field of oblique single-axis tracking photovoltaic bracket technology, and more specifically, to an oblique single-axis tracking photovoltaic bracket. Background Technology

[0002] A tilted single-axis tracking photovoltaic (PV) bracket refers to a system that connects PV panels via a single rotating shaft. This shaft is tilted to better align the PV panels with the geographical latitude. By controlling the rotation of the shaft, the angle of the PV panels can be changed, thus tracking the movement of the sun.

[0003] However, existing inclined single-axis tracking photovoltaic brackets require a certain degree of flatness of the ground during installation in order to adapt to the tilt angle of the photovoltaic panels. If the road surface has a certain tilt angle or has bumps, the bracket itself will be tilted during installation, which will affect the tilt angle of the photovoltaic panels and thus affect the sunlight. Summary of the Invention

[0004] The purpose of this invention is to provide a single-axis inclined photovoltaic support, which solves the problem that if the road surface where the single-axis inclined photovoltaic support is installed has an inclined angle or is uneven with protrusions, the support itself will tilt, causing the tilt angle of the photovoltaic panel to change, making it impossible to accurately align with direct sunlight.

[0005] This invention is achieved through the following technical solution: This invention provides a single-axis tracking photovoltaic support bracket, comprising a bracket with support rods at the top of both ends of the bracket. The two support rods are at different heights and are connected by a rotating rod. A connecting block is provided on the side wall of the rotating rod. A photovoltaic panel is bolted to the top of the connecting block. A mating strip is connected to the bottom of the bracket. A lifting rod is protruding from the top of the mating strip. A connecting cavity is opened inside the bracket. A deflection block is connected to the middle of the connecting cavity. A pressing slope protrudes from one side of the deflection block. An abutment block is provided at the bottom of the deflection block.

[0006] Preferably, the mating strip is connected to the bottom of the bracket via a top lifting rod, with the protruding part of the lifting rod in the connecting cavity.

[0007] Preferably, the connecting cavity further includes a fitting groove and a rack, the fitting groove being formed on one side of the middle portion of the connecting cavity, and the rack being disposed on one side of the middle portion of the fitting groove.

[0008] Preferably, the lifting rod further includes a fitting rod, a transmission rod, an arc-shaped block, and an extension opening. The fitting rod is disposed on one side of the lifting rod, the transmission rod is connected inside the lifting rod, the arc-shaped block is hinged to the bottom sides of the transmission rod, and the extension opening is opened at the bottom of the mating strip.

[0009] Preferably, the fitting rod engages with the fitting groove, and the side wall of the fitting rod is provided with a gear that meshes with the rack.

[0010] Preferably, one side of the transmission rod is in contact with one side of the fitting rod, and the side of the transmission rod in contact with the fitting rod is engaged by a rack.

[0011] Preferably, the arc-shaped block is an arc-shaped plate hinged to both sides of the bottom of the transmission rod, and the arc-shaped block is located in the extension opening.

[0012] Preferably, the bottom portion of the arc-shaped block is connected to the hinged arc-shaped block via a torsion spring.

[0013] Preferably, one side of the lifting rod is provided with tooth marks, and the abutment block is a triangular protrusion extending obliquely from the bottom of the deflection block, and the triangular end point of the abutment block engages with the tooth marks on one side of the lifting rod.

[0014] Preferably, the deflection block is connected by a central hinge shaft, and torsion springs are provided at both ends of the central hinge shaft of the deflection block.

[0015] The technical solution of the present invention has at least the following advantages and beneficial effects: 1. The device uses a matching strip that rises to different degrees depending on the angle of inclination of the inclined road surface when in contact with it, thereby forming an inclined surface that matches the angle of inclination of the inclined road surface, allowing the support to be placed parallel to the inclined road surface.

[0016] 2. The device is also equipped with an arc-shaped block. When the mating strip rises with the inclined road surface, the transmission arc-shaped block will move down to contact the ground and deflect. The arc-shaped block itself increases the resistance to sliding of the mating strip and also allows the suspended part of the long mating strip to be supported on the road surface, making the placement of the mating strip more stable.

Detailed Implementation

[0024] The following is combined with Figures 1 to 6 The present invention will be described in detail below.

[0025] A single-axis tracking photovoltaic bracket includes a bracket 1. Support rods 101 are provided at the top of both ends of the bracket 1. The two support rods 101 are at different heights. A rotating rod 2 is connected between the two support rods 101. A connecting block 201 is provided on the side wall of the rotating rod 2. A photovoltaic panel 3 is bolted to the top of the connecting block 201. A mating strip 4 is connected to the bottom of the bracket 1. A lifting rod 401 is provided on the top of the mating strip 4. A connecting cavity 103 is opened inside the bracket 1. A deflection block 104 is connected to the middle of the connecting cavity 103. A pressing inclined surface 1041 extends protruding from one side of the deflection block 104. An abutment block 1042 is provided at the bottom of the deflection block 104.

[0026] First, the bracket 1 is placed flat on the ground. Then, the photovoltaic panel 3 is connected to the connecting block 201 on the side wall of the rotating rod 2. Since the rotating rod 2 is connected between two support rods 101 of different heights, the rotating rod 2 itself will be tilted, which will also make the connected photovoltaic panel 3 tilted, so that the photovoltaic panel 3 has an angle, which is more in line with the geographical latitude and more in line with the movement trajectory of the sun from east to west.

[0027] Furthermore, the mating strip 4 is connected to the bottom of the bracket 1 via the top lifting rod 401. The protruding part of the lifting rod 401 is in the connecting cavity 103. The connecting cavity 103 also includes a fitting groove 1031 and a rack 1032. The fitting groove 1031 is opened on one side of the middle part of the connecting cavity 103, and the rack 1032 is set on one side of the middle part of the fitting groove 1031. The deflection block 104 is connected via a central hinge shaft, and torsion springs are provided at both ends of the central hinge shaft of the deflection block 104.

[0028] Meanwhile, when the bracket 1 is laid flat on the ground, the bottom mating strip 4 will contact the ground first. If the ground has a certain slope, when several mating strips 4 are laid flat along with the bracket 1, one end of the mating strip 4 will contact the ground first. The remaining mating strips 4 will not immediately contact the ground due to the slope of the road. When the mating strip 4 at one end contacts the ground first, it will be pressed by the pressure of the lowering and the weight of the bracket 1 itself. The mating strip 4 will rise into the inside of the bracket 1 through the lifting rod 401 at the top. Then, during the lowering process, the mating strip 4 will contact the sloped ground in sequence. Several mating strips 4 will also form a slope angle to match the sloped ground due to different degrees of rising, so as to adapt to the slope of the ground. This allows the bracket 1 to maintain a parallel state when placed on the sloped ground, avoiding changes in the slope angle of the photovoltaic panel and affecting the sunlight.

[0029] Furthermore, the lifting rod 401 also includes a fitting rod 4011, a transmission rod 4012, an arc-shaped block 4013, and an extension opening 4014. The fitting rod 4011 is disposed on one side of the lifting rod 401, the transmission rod 4012 is connected inside the lifting rod 401, the arc-shaped block 4013 is hinged to both sides of the bottom of the transmission rod 4012, and the extension opening 4014 is opened at the bottom of the mating strip 4. The fitting rod 4011 mates with the fitting groove 1031, and the side wall of the fitting rod 4011 is provided with a gear that meshes with the rack 1032. One side of the transmission rod 4012 is connected to the fitting groove 1031. The connecting rod 4011 is attached to one side, and the transmission rod 4012 is attached to one side of the fitting rod 4011 through a rack and pinion. The arc-shaped block 4013 is an arc-shaped plate that is hinged to both sides of the bottom of the transmission rod 4012, and the arc-shaped block 4013 is set in the extension opening 4014. The bottom part of the arc-shaped block 4013 is connected by a torsion spring. The lifting rod 401 has tooth marks on one side. The abutment block 1042 is a triangular protrusion that extends obliquely from the bottom of the deflection block 104, and the triangular end of the abutment block 1042 is engaged with the tooth marks on one side of the lifting rod 401.

[0030] As the mating bar 4 closest to one end rises under pressure, the lifting rod 401 extends into the connecting cavity 103. Simultaneously, it first abuts against the pressing slope 1041 on one side of the deflection block 104 within the connecting cavity 103. The continuous rise of the lifting rod 401 compresses the pressing slope 1041, forcing the deflection block 104 to deflect along the central hinge axis. Once the deflection block 104 deflects, the abutment block 1042 at the bottom of the deflection block 104 approaches the toothed area on one side of the lifting rod 401. The pointed end of the abutment block 1042 abuts against the groove of the toothed area, thus limiting the lifting rod 401 and preventing it from rising further. This also limits the position of other mating bars 4 without a designated spot, ensuring they maintain their rising distance and conform to the angle of the ground's inclination, preventing them from rising on their own and making the placement of the mating bar 4 against the slope more stable.

[0031] Simultaneously, during the ascent of the lifting rod 401, the engaging rod 4011 connected to one side of the lifting rod 401 engages in the engaging groove 1031 for further ascent. Because the side wall of the engaging rod 4011 meshes with the rack 1032 on one side of the middle of the engaging groove 1031, the engaging rod 4011 rotates by meshing with the rack 1032 as it rises with the lifting rod 401. When the engaging rod 4011 rotates, its side wall also meshes with the transmission rod 4012 inside the lifting rod 401. On the side, the rotation of the interlocking rod 4011 engages the transmission rod 4012 to move downward. When the transmission rod 4012 moves downward, it will also drive the bottom arc block 4013 to move downward. When the arc block 4013 moves downward, it will contact the ground. Because the mating strip 4 itself is long and narrow, on a road surface with a certain angle of inclination, part of it will not be able to contact the ground. However, the downward movement of the arc block 4013 will fit and support the ground, increasing the stability of the mating strip 4.

[0032] Meanwhile, if the curved block 4013 contacts the ground and the lifting rod 401 is still moving upward, the curved block 4013 will continue to move downward to apply pressure. This is because the curved block 4013 itself consists of two plates that are bent and tilted to both sides. When under pressure, the two curved blocks 4013 will deflect to both sides to accommodate the downward movement of the curved block 4013. If the ground is soil, when the curved block 4013 is applying downward pressure and deflecting to both sides, part of it will be inserted into the soil for a stable connection. The curved structure of the curved block 4013 itself also increases the resistance to the sliding of the mating strip 4 to both sides. Thus, when the mating strip 4 is placed on the ground, the curved block 4013 can provide a certain degree of anti-slip, preventing the mating strip 4 from easily sliding when it is placed on an inclined surface.

[0033] Finally, the combination of several mating strips 4 can form a slope, and if there are protrusions on the road surface, the part that contacts the protrusion can shrink in advance to form a groove, so that it can be placed parallel in areas where there are protrusions on the road surface.

[0034] The following is a specific implementation process of the present invention. First, the bracket 1 is placed flat on the ground. Then, the photovoltaic panel 3 is connected to the connecting block 201 on the side wall of the rotating rod 2. Because the rotating rod 2 is connected between two support rods 101 of different heights, the rotating rod 2 itself will be tilted, so that the connected photovoltaic panel 3 will also be tilted, making the photovoltaic panel 3 have an angle, which is more in line with the geographical latitude and more in line with the trajectory of the sun from east to west.

[0035] Meanwhile, when the bracket 1 is laid flat on the ground, the bottom mating strip 4 will contact the ground first. If the ground has a certain slope, when several mating strips 4 are laid flat along with the bracket 1, one end of the mating strip 4 will contact the ground first. The remaining mating strips 4 will not immediately contact the ground due to the slope of the road. When the mating strip 4 at one end contacts the ground first, it will be pressed by the pressure of the lowering and the weight of the bracket 1 itself. The mating strip 4 will rise into the inside of the bracket 1 through the lifting rod 401 at the top. Then, during the lowering process, the mating strip 4 will contact the sloped ground in sequence. Several mating strips 4 will also form a slope angle to match the sloped ground due to different degrees of rising, so as to adapt to the slope of the ground. This allows the bracket 1 to maintain a parallel state when placed on the sloped ground, avoiding changes in the slope angle of the photovoltaic panel and affecting the sunlight.

[0036] As the mating bar 4 closest to one end rises under pressure, the lifting rod 401 extends into the connecting cavity 103. Simultaneously, it first abuts against the pressing slope 1041 on one side of the deflection block 104 within the connecting cavity 103. The continuous rise of the lifting rod 401 compresses the pressing slope 1041, forcing the deflection block 104 to deflect along the central hinge axis. Once the deflection block 104 deflects, the abutment block 1042 at the bottom of the deflection block 104 approaches the toothed area on one side of the lifting rod 401. The pointed end of the abutment block 1042 abuts against the groove of the toothed area, thus limiting the lifting rod 401 and preventing it from rising further. This also limits the position of other mating bars 4 without a designated spot, ensuring they maintain their rising distance and conform to the angle of the ground's inclination, preventing them from rising on their own and making the placement of the mating bar 4 against the slope more stable.

[0037] Simultaneously, during the ascent of the lifting rod 401, the engaging rod 4011 connected to one side of the lifting rod 401 engages in the engaging groove 1031 for further ascent. Because the side wall of the engaging rod 4011 meshes with the rack 1032 on one side of the middle of the engaging groove 1031, the engaging rod 4011 rotates by meshing with the rack 1032 as it rises with the lifting rod 401. When the engaging rod 4011 rotates, its side wall also meshes with the transmission rod 4012 inside the lifting rod 401. On the side, the rotation of the interlocking rod 4011 engages the transmission rod 4012 to move downward. When the transmission rod 4012 moves downward, it will also drive the bottom arc block 4013 to move downward. When the arc block 4013 moves downward, it will contact the ground. Because the mating strip 4 itself is long and narrow, on a road surface with a certain angle of inclination, part of it will not be able to contact the ground. However, the downward movement of the arc block 4013 will fit and support the ground, increasing the stability of the mating strip 4.

[0038] Meanwhile, if the arc-shaped block 4013 contacts the ground and the lifting rod 401 is still moving upward, the arc-shaped block 4013 will continue to move downward to apply pressure. This is because the arc-shaped block 4013 itself consists of two plates that are bent and tilted to both sides. When under pressure, the two arc-shaped blocks 4013 will deflect to both sides to adapt to the downward movement of the arc-shaped block 4013. If the ground is soil, when the arc-shaped block 4013 is applying downward pressure and deflecting to both sides, part of it will be inserted into the soil for a stable connection. The arc-shaped structure of the arc-shaped block 4013 itself also increases the resistance to the sliding of the mating strip 4 to both sides. Thus, when the mating strip 4 is placed on the ground, the arc-shaped block 4013 can provide a certain degree of anti-slip, preventing the mating strip 4 from easily sliding when it is placed on an inclined road surface. Finally, when several mating strips 4 are combined together, they can form an inclined surface. If there is a protrusion on the road surface, the part that contacts the protrusion can contract in advance to form a groove, so that it can be placed parallel in areas with protrusions on the road surface.
