Description

Technical Field

[0001] The invention relates to the field of photovoltaic supports, and in particular to an angle adjustment device for a photovoltaic vertical pile support. Background Art

[0002] Photovoltaic power generation system is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar energy into electrical energy. Solar energy is an inexhaustible clean energy, which reduces dependence on traditional fossil energy such as coal and oil, and improves the security and independence of energy supply.

[0003] In various photovoltaic power generation projects, whether it is a large-scale centralized photovoltaic power station or a widely distributed photovoltaic power generation system, photovoltaic brackets play a vital role. They are key components that support photovoltaic modules and ensure their efficient operation.

[0004] The position of the sun in the sky changes with the seasons and time, and the solar altitude and azimuth angles vary significantly in different regions. In order to keep the photovoltaic modules at the best angle to receive sunlight and maximize the capture of solar energy, the brackets used to support the photovoltaic modules need to be set as adjustable devices.

[0005] At present, in the disclosed technology, there are many types of brackets that can adjust the tilt angle of photovoltaic modules. For example, a Chinese patent with the publication number CN112671318A discloses a photovoltaic bracket, which includes purlins for supporting photovoltaic modules, columns for vertically fixing on a horizontal mounting surface, main beams installed laterally on the columns, and supports for mounting the purlins on the main beams. It also includes a first driving mechanism, a movable component, a fixing component, and a second driving mechanism. The movable component is positioned on the column and is provided with a first tooth pattern, the fixing component is fixed on the main beam and is provided with a second tooth pattern, and the first driving mechanism drives the movable component so that the first tooth pattern and the second tooth pattern have two states of separation and engagement in the vertical direction. In the separated state of the first tooth pattern and the second tooth pattern, the second driving mechanism drives the main beam to rotate to adjust the angle.

[0006] The bracket provided by the above patent can control the rotation of the photovoltaic module around the axis according to the demand, and then adjust the tilt angle of the photovoltaic module, so as to make it possible for the sunlight to irradiate the photovoltaic module vertically and capture as much solar energy as possible. As we all know, the position of the sun changes from the rising of the sun to the setting of the sun, and the above bracket is not convenient to adjust the direction of the photovoltaic module according to the movement of the sun from east to west, resulting in very little sunlight being able to irradiate the photovoltaic module vertically.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The following is a further description with reference to the accompanying drawings and specific embodiments: Embodiment 1

[0039] In order to be able to adjust the orientation of the photovoltaic module over a large range according to the movement of the sun during the day, and to reduce the contact area between the strong wind and the photovoltaic module in strong wind weather, the present embodiment provides a bracket for the photovoltaic module (i.e., the photovoltaic panel 1), which can control the rotation of the photovoltaic panel 1 around the horizontal axis and the vertical axis according to demand, thereby achieving a large range of adjustment of the photovoltaic panel 1.

[0040] like Figure 1 , Figure 4 , Figure 6 As shown, specifically, the bracket includes a frame 11, a connecting mechanism 3, an intermediate member 2, a pile body 16, etc., which are arranged from top to bottom. A plurality of purlins 12 are fixedly connected and arranged above the frame 11 through a first connecting member 13, and a plurality of photovoltaic panels 1 are laid on the plane formed by the plurality of purlins 12. The bottom of the pile body 16 is connected and installed on a concrete base by bolts. The intermediate member 2 is arranged on the top of the pile body 16 by bolt connection, and the intermediate member 2 is adjustable and sleeved on the bottom column of the connecting mechanism 3. At the same time, the connecting mechanism 3 is installed below the frame 11. In addition, the connecting mechanism 3 is set to an adjustable state. In order to control the frame 11 to drive the photovoltaic panel 1 to rotate around the vertical axis, a first driving component 4 is arranged below the intermediate member 2. The first driving component 4 is arranged in the pile body 16. Under the action of the first driving component 4, the connection mechanism 3 and the intermediate member 2 can be contacted. The restrictions, and the connection mechanism 3 is controlled to rotate relative to the intermediate member 2 under the action of the first driving component 4. In order to control the frame 11 to drive the photovoltaic panel 1 to rotate around the horizontal axis, a second driving assembly 5 is provided on the connecting mechanism 3, and the second driving assembly 5 can control the deformation of the connecting mechanism 3, thereby controlling the frame 11 to adjust the tilt angle. In summary, the cooperation between the first driving assembly 4 and the second driving assembly 5 can achieve a wide range of adjustment of the state of the photovoltaic panel 1.

[0041] like Figure 7As shown, in order to be able to adjust the inclination angle of the photovoltaic panel 1, the connecting mechanism 3 includes a middle frame 31 and two arc plates 32, and the central angles of the arc plates 32 and the middle frame 31 are both set to 180°. The two arc plates 32 are installed below the frame 11, and the middle frame 31 is connected to the middle member 2 through a bottom column. Therefore, the inclination angle of the frame 11 can be adjusted by rotating the arc plates 32 relative to the middle frame 31, thereby realizing the adjustment of the inclination angle of the photovoltaic panel 1.

[0042] like Figure 7 As shown, in order to achieve a stable connection between the middle frame 31 and the arc plate 32, a buckle arc groove 33 is provided on the side walls of the middle frame 31 and the arc plate 32 that are close to each other, and the center angle of the cross section of the buckle arc groove 33 is greater than 180°, and a second connecting member 36 is provided in the space formed by the two connected buckle arc grooves 33, and the second connecting member 36 is composed of two balls connected, and the two balls are respectively arranged in the two buckle arc grooves 33, so that under the action of the second connecting member 36, the middle frame 31 and the arc plate 32 are stably and movably connected. In order to limit the movement of the second connecting member 36, the end of the buckle arc groove 33 on the middle frame 31 is set to a closed structure, for example, a plate body can be welded at the end of the buckle arc groove 33, thereby blocking the position of the second connecting member 36, and providing support for the movement of the arc plate 32 relative to the middle frame 31.

[0043] like Figure 8 As shown, in order to force the arc plate 32 to rotate relative to the middle frame 31, the second driving assembly 5 includes a second motor 51 and a first gear 52. The second motor 51 (which can be set as a servo motor, a stepping motor, etc.) is installed on the arc plate 32, and the first gear 52 is installed on the power output shaft of the second motor 51. A first rack 34 is arranged at the edge of the middle frame 31, and the first gear 52 is meshed and connected with the first rack 34. Therefore, when the second motor 51 is working, the first gear 52 can be controlled to rotate, thereby driving the arc plate 32 to move relative to the middle frame 31.

[0044] like Figure 7 , Figure 8As shown, in order to make the arc plate 32 and the middle frame 31 relatively stable after relative movement, that is, to control the photovoltaic panel 1 to be at a stable tilt angle, the second driving assembly 5 also includes a second gear 54, a central shaft 541, a first electromagnet 58, a second electromagnet 59, a second spring 55, a baffle 56, etc. The end of the central shaft 541 is connected and inserted into the support plate 57 through a bearing, and the support plate 57 is fixedly mounted on the middle frame 31, and the second gear 54 is movably sleeved on the central shaft 541. At the same time, a second rack 35 is arranged on the other edge of the middle frame 31, and a third rack 37 is arranged on the arc plate 32 adjacent to the second rack 35. The second rack 35 and the third rack 37 are the same as the first rack 34, except that the width of the second rack 35 is smaller than that of the third rack 37 and smaller than that of the second gear 54. When the second motor 51 works to control the arc plate 32 to move relative to the middle frame 31, the second gear 54 is meshed with the third rack 37. Since the second gear 54 is the same as the first gear 52, the second gear 54 rotates synchronously with the first gear 52. When the arc plate 32 moves a corresponding distance, the second gear 54 moves from the third rack 37 to the second rack 35, that is, the second gear 54 is meshed with the second rack 35 and the third rack 37 at the same time, and then the arc plate 32 and the middle frame 31 are restricted to remain relatively still under the action of the second gear 54, so that the photovoltaic panel 1 is at a stable tilt angle.

[0045] like Figure 8 , Fig. 9As shown, in order to control the movement of the second gear 54, the mutually repelling first electromagnet 58 and the second electromagnet 59 are arranged on the same side of the second gear 54, and the first electromagnet 58 is fixedly connected to the central axis 541, and the second electromagnet 59 is installed on the second gear 54. Therefore, when the first electromagnet 58 and the second electromagnet 59 are energized, they move away from each other under the action of magnetic force, thereby controlling the second gear 54 to move along the length direction of the central axis 541. In addition, the mutually repelling first electromagnet 58 and the second electromagnet 59 can also be arranged on the other side of the second gear 54. The electromagnets on both sides work intermittently, so as to control the second gear 54 to move left and right along the length direction of the central axis 541, and provide support for the second gear 54 to be engaged with the third rack 37 alone, or to be engaged with the second rack 35 and the third rack 37 at the same time. Alternatively, a second spring 55 and a baffle 56 are provided on the other side of the second gear 54. The second spring 55 is sleeved on the central shaft 541, and the second spring 55 is in a compressed state. At the same time, the two ends of the second spring 55 are respectively connected to the second gear 54 and the baffle 56. In addition, the baffle 56 is fixedly provided on the central shaft 541. Therefore, with the cooperation of the second spring 55 and the first electromagnet 58 and the second electromagnet 59 on the other side, the second gear 54 can be controlled to move left and right along the length direction of the central shaft 541, so as to provide support for the second gear 54 to be engaged with the third rack 37 alone, or to be engaged with the second rack 35 and the third rack 37 at the same time.

[0046] like Fig.10 As shown, in order to make the middle frame 31 movably connected to the middle piece 2, the middle piece 2 includes an annular base plate 25, a fixed arc plate 22 and an arc clamping plate 21. The central angles of the fixed arc plate 22 and the arc clamping plate 21 are both set to 180°, and the outer diameter of the spliced ​​tube body is equal to the outer diameter of the annular base plate 25. At the same time, the inner diameter of the spliced ​​tube body is larger than the inner diameter of the annular base plate 25. In addition, the arc clamping plate 21 is detachably arranged on the side of the fixed arc plate 22 by bolts, and the fixed arc plate 22 is fixedly arranged on the annular base plate 25.

[0047] like Fig.10 As shown, a second annular groove 38 is provided on the side wall of the bottom column of the middle frame 31, and a first annular groove 23 is provided on the inner side surfaces of the fixed arc plate 22 and the arc clamping plate 21. A plurality of rollers 24 are provided in the space formed by the first annular groove 23 and the second annular groove 38. Therefore, with the cooperation of the rollers 24 and the annular grooves, the bottom column is stably installed in the middle piece 2, so that the middle frame 31 is movably connected to the middle piece 2.

[0048] like Fig.11As shown, in the case where the middle frame 31 and the middle piece 2 are movably connected, in order to control the middle frame 31 to drive the frame 11 and the photovoltaic panel 1 to rotate around the vertical axis, the first driving assembly 4 includes an electric cylinder 41, a first motor 44 (which can be set as a servo motor, a stepping motor, etc.) and a driving wheel 46. The electric cylinder 41 and the first motor 44 are both inverted. The first motor 44 is installed at the telescopic end of the top of the electric cylinder 41, and the electric cylinder 41 is installed in the pile body 16. Therefore, when the electric cylinder 41 is working, the first motor 44 can be controlled to rise and fall. The driving wheel 46 is set at the top output shaft of the first motor 44, and a driven groove 312 is set on the bottom surface of the bottom column of the middle frame 31. The driven groove 312 and the driving wheel 46 are set as matching concave-convex structures. Therefore, when the electric cylinder 41 works to lift the first motor 44 and the driving wheel 46 extends into the driven groove 312, the middle frame 31 can be controlled to rotate under the action of the first motor 44, and then the photovoltaic panel 1 can be controlled to rotate around the vertical axis.

[0049] In order to enable the middle frame 31 to be stably placed relative to the middle piece 2 after rotating around the axis, an insertion rod 39 is fixedly provided on the edge of the bottom of the middle frame 31, and a plurality of slots 26 are provided on the upper side of the annular bottom plate 25. The plurality of slots 26 are located on the inner side of the fixed arc plate 22 and the arc-shaped clamping plate 21, and the plurality of slots 26 are evenly distributed along the circumferential direction of the annular bottom plate 25. Therefore, when the insertion rod 39 is inserted into a certain slot 26, the middle frame 31 can be installed statically relative to the middle piece 2 with the cooperation of the insertion rod 39 and the slot 26.

[0050] When the insertion rod 39 and the slot 26 are provided, in order not to affect the rotation of the middle frame 31 around the axis, a second bracket 43 is provided at the bottom of the first motor 44 by bolts, and a support plate 45 is fixedly provided on the side of the second bracket 43, and the top surface of the support plate 45 is lower than the top surface of the driving wheel 46. Therefore, after the electric cylinder 41 lifts the first motor 44 to make the driving wheel 46 extend into the driven slot 312, the top of the support plate 45 contacts the bottom of the middle frame 31. When the electric cylinder 41 continues to work, the bottom column of the middle frame 31 can be controlled to rise, thereby making the insertion rod 39 disengage from the slot 26, and releasing the restriction of the middle frame 31 and the middle member 2. After the middle frame 31 rotates around the axis, the electric cylinder 41 works again to reduce its own length, so that the middle frame 31 descends, and the insertion rod 39 is inserted into the slot 26, so that the middle frame 31 and the photovoltaic panel 1 can be stably installed.

[0051] In order to control the lifting and lowering of the middle frame 31, the height of the first annular groove 23 is greater than the height of the second annular groove 38, and the height of the second annular groove 38 should be slightly greater than the height of the roller 24. At the same time, the height difference between the first annular groove 23 and the second annular groove 38 is greater than the height of the insertion rod 39, which facilitates the lifting and lowering of the middle frame 31.

[0052] like Figure 5 , Fig.11As shown, in order to stably install the electric cylinder 41 in the pile body 16, a slide groove 17 is provided at the top of the inner wall of the pile body 16. The slide groove 17 is provided along the height direction of the pile body 16, and the top of the slide groove 17 is provided as an opening. A first bracket 42 is detachably provided at the top of the electric cylinder 41 by bolts, and the end of the first bracket 42 extends into the slide groove 17, and the first bracket 42 can be connected to the pile body 16 by bolts. The second bracket 43 is connected to the telescopic end of the electric cylinder 41, and the end of the second bracket 43 extends into the slide groove 17, and the end of the second bracket 43 is in sliding contact with the side wall of the slide groove 17. The side of the contact surface can be made smoother by grinding, polishing and other processes to reduce the surface roughness of the material, or a coating (such as molybdenum disulfide) is applied on the contact surface to reduce the friction coefficient.

[0053] In order to control the operation of the device, an electrical control box is also required, which at least includes a contactor, a relay, a controller (such as a PLC), a human-machine interface (such as an HMI), a power module, a terminal block, etc. The electrical control box can be connected to the control center through serial communication, Ethernet communication, field bus communication and other publicly available methods to obtain instructions from the control center. In addition, according to the disclosed technology, the power lines and signal lines of the motor, electric cylinder and electromagnet are connected to the corresponding interfaces of the terminal block, so that the electrical control box controls the operation of the motor and electric cylinder to adjust the state of the photovoltaic panel 1. In order to facilitate the connection of the motor and electric cylinder in the pile body 16, an inclined hole 18 is provided on the pile body 16, and the lowest end of the inclined hole 18 is located on the outside of the pile body 16, and the cable can pass through the inclined hole 18 and extend into the pile body 16. Embodiment 2

[0054] like Fig.12 As shown, on the basis of Example 1, the bottom column of the middle frame 31 is connected and installed in the space formed by the annular bottom plate 25, the fixed arc plate 22 and the arc clamping plate 21 through a bearing (such as a roller bearing, a thrust bearing), so as to realize the movable connection between the middle frame 31 and the middle member 2.

[0055] like Fig.13 , Fig.14As shown, in the case where the middle frame 31 and the middle piece 2 are movably connected, in order to control the middle frame 31 to drive the frame 11 and the photovoltaic panel 1 to rotate around the vertical axis, the first driving assembly 4 includes an electric cylinder 41, a first motor 44 (which can be set as a servo motor, a stepping motor, etc.) and a driving wheel 46. The electric cylinder 41 and the first motor 44 are both inverted. The first motor 44 is installed at the telescopic end of the top of the electric cylinder 41, and the electric cylinder 41 is installed in the pile body 16. Therefore, when the electric cylinder 41 is working, the first motor 44 can be controlled to rise and fall. The driving wheel 46 is set at the top output shaft of the first motor 44, and a driven groove 312 is set on the bottom surface of the bottom column of the middle frame 31. Therefore, when the electric cylinder 41 works to lift the first motor 44 and the driving wheel 46 extends into the driven groove 312, the middle frame 31 can be controlled to rotate under the action of the first motor 44, thereby controlling the photovoltaic panel 1 to rotate around the vertical axis.

[0056] In order to ensure that the middle frame 31 can be stably placed relative to the middle piece 2 after rotating around the axis, an annular groove 311 is provided on the bottom surface of the bottom column of the middle frame 31, a brake pipe 48 is provided at the annular groove 311, and a first spring 49 is provided on the top of the brake pipe 48. The first spring 49 is in a compressed state, and the top is in contact with the annular groove 311. A plurality of through holes 27 are provided on the annular bottom plate 25. Under the action of the first spring 49, the bottom of the brake pipe 48 is inserted into a through hole 27, thereby limiting the relative static installation of the middle frame 31 and the middle piece 2.

[0057] In order to release the restrictions of the middle frame 31 and the middle piece 2 and control the rotation of the middle frame 31 under the action of the first motor 44, a second bracket 43 is arranged at the bottom of the first motor 44, and a lifting ring plate 47 is fixedly arranged above the second bracket 43. A plurality of jacking pipes 471 are arranged on the lifting ring plate 47. The jacking pipes 471 are matched with the through holes 27 one by one, and the tops of the jacking pipes 471 are inserted into the through holes 27. At the same time, the top surfaces of the jacking pipes 471 are higher than the top surfaces of the driving wheels 46. Therefore, when the electric cylinder 41 controls the first motor 44 to rise, the jacking pipes 471 lift the brake pipe 48 and compress the first spring 49, so that the brake pipe 48 is disengaged from the through hole 27, and the top surface of the jacking pipe 471 is flush with the top surface of the annular bottom plate 25. At the same time, the driving wheel 46 extends into the driven groove 312, so that the middle frame 31 can be controlled to rotate around the axis by the first motor 44. The end surfaces of the top tube 471 and the brake tube 48 that are close to each other are respectively provided with magnets 472 that repel each other, so that a gap is left between the brake tube 48 and the top surface of the annular bottom plate 25, and the top surface of the magnet 472 arranged on the top tube 471 is flush with the top surface of the annular bottom plate 25. After the middle frame 31 rotates around the axis, the electric cylinder 41 works again, reducing its own length, so that the middle frame 31 descends, and the brake tube 48 is inserted into the through hole 27, so that the middle frame 31 and the photovoltaic panel 1 can be stably installed.

[0058] The difference between this embodiment and Embodiment 1 lies in that the connection mode between the middle frame 31 and the middleware 2 has changed, and at the same time, the structure of the first driving component 4 has been adjusted. Embodiment Three

[0059] As Figure 2 、 Figure 3 shown, on the basis of Embodiment 1 or 2, in order to stably install the photovoltaic panel 1 on the purlin 12, the first connecting member 13 is set as a C-shaped structure, and a buckle groove 14 is provided at the top, and at the same time, a connecting bolt 15 is threadedly penetrated through the bottom. During use, the first connecting member 13 is sleeved on the purlin 12, and the buckle groove 14 is sleeved on the angle iron added under the photovoltaic panel 1, and at the same time, the connecting bolt 15 presses against the bottom surface of the purlin 12, so as to stably install the photovoltaic panel 1 relative to the purlin 12. At present, since the photovoltaic panel 1 has been disclosed, it is briefly introduced here. It includes solar cells (divided into types such as monocrystalline silicon, polycrystalline silicon, and amorphous silicon (thin film)), encapsulation materials (EVA film, backplane), glass cover plate, frame, and junction box.
