Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic panel brackets, in particular to a double-push rod adjustable photovoltaic bracket. Background Art
[0002] With the growing global demand for clean energy, solar photovoltaic power generation has been widely used as a sustainable energy solution. In solar photovoltaic systems, photovoltaic brackets are used to install and fix solar photovoltaic panels.
[0003] Traditional photovoltaic brackets have certain limitations in adjusting the angle of photovoltaic panels to adapt to changes in the position of the sun. The angle of sunlight changes with time and seasons, and traditional solar photovoltaic panel installation methods are often fixed and cannot automatically adjust the horizontal orientation and pitch angle of the photovoltaic panels according to changes in the angle of sunlight. This causes the photovoltaic panels to not always face the direction of the strongest sunlight, greatly affecting the efficiency of the solar photovoltaic panels in receiving solar energy and failing to fully exert their maximum power generation efficiency. When solar photovoltaic panels work in high temperature environments in summer, as the temperature rises, the power generation efficiency of the solar photovoltaic panels will decrease. Some existing solar photovoltaic panel heat dissipation measures only rely on simple natural heat dissipation methods and lack effective heat conduction and heat dissipation structures. When natural heat dissipation cannot meet the needs, there is a lack of corresponding active heat dissipation mechanisms to accelerate air flow to enhance the heat dissipation effect and ensure the normal operation of photovoltaic panels in high temperature environments. If the heat of the photovoltaic panels cannot be dissipated in time, it will accumulate inside the photovoltaic panels, resulting in reduced power generation efficiency of the photovoltaic panels.

The upper end of the support rod 4 is provided with an installation equipment bracket 5. The upper end of the support rod 4 is hinged to the lower surface of the installation equipment bracket 5. The support rod 4 is used to support the installation equipment bracket 5 and rotate the installation equipment bracket 5. A heat dissipation structure 6 is provided inside the installation equipment bracket 5. The heat dissipation structure 6 includes a heat conducting plate 10 and a heat dissipation fin 11. A solar photovoltaic panel 12 is fixedly connected to the upper surface of the installation equipment bracket 5. The installation equipment bracket 5 facilitates the installation of the solar photovoltaic panel 12. The heat dissipation structure 6 is used to dissipate heat from the solar photovoltaic panel 12.
[0022] During the specific implementation process, two groups of fixing plates 13 are fixedly connected to the upper surface of the base plate 1, and through holes are opened on the side surfaces of the two groups of fixing plates 13. The two ends of the worm 8 are rotatably connected to the inside of the through holes on the side surfaces of the two groups of fixing plates 13. The fixing plates 13 are used to install the worm 8 without hindering the rotation of the worm 8. One end of the worm 8 is fixedly connected to the power output end of the servo motor 9. The bottom of the servo motor 9 is fixedly connected to the upper surface of the base plate 1. The servo motor 9 is electrically connected to the external power supply. The servo motor 9 is started, and the rotation of the power output end of the servo motor 9 can drive the worm 8 to rotate.
[0023] Among them, the lower end of the support rod 4 passes through the through hole on the upper surface of the mounting seat 2 and is rotatably connected to the upper surface of the base plate 1. The support rod 4 can rotate inside the through hole on the upper surface of the mounting seat 2. The middle part of the worm gear 7 is fixedly connected to the outer surface of the lower end of the support rod 4. Since the worm gear 7 is engaged with the worm 8, the worm gear 7 is driven to rotate when the worm 8 rotates, and the worm gear 7 is driven to rotate when the worm 8 rotates, and the support rod 4 is driven to rotate when the worm gear 7 rotates, and the worm 8 has a limiting effect on the worm gear 7 to prevent the support rod 4 from rotating. The side surface of the support rod 4 is fixedly connected to a cross bar 14, and the upper surfaces of both ends of the cross bar 14 are respectively fixedly connected to a group of connecting seats 15. The side surfaces of the two groups of connecting seats 15 A group of electric push rods 16 are hinged respectively, and the ejection ends of the two groups of electric push rods 16 are hinged to the lower surface of the installation equipment bracket 5 respectively. The electric push rods 16 are electrically connected to the external power supply. When the electric push rods 16 are started, the ejection ends of the electric push rods 16 are hinged to the lower surface of the installation equipment bracket 5. The bottom of the electric push rods 16 is connected to the support rod 4 through the hinge with the connecting seat 15 and the cross bar 14. When the electric push rods 16 are extended or retracted, since their two ends are respectively hinged with the installation equipment bracket 5 and the support rod 4, they will push the installation equipment bracket 5 to rotate around the hinge point at the upper end of the support rod 4, thereby realizing the adjustment of the pitch angle of the installation equipment bracket 5.
[0024] The working principle of this embodiment is as follows:
[0025] When the servo motor 9 is started, the power output end of the servo motor 9 rotates to drive the worm 8 to rotate. Since the worm 8 is engaged with the worm wheel 7, the rotation of the worm 8 will cause the worm wheel 7 to rotate, and the middle part of the worm wheel 7 is fixedly connected to the outer surface of the lower end of the support rod 4. The lower end of the support rod 4 passes through the through hole on the upper surface of the mounting seat 2 and is rotatably connected to the upper surface of the base plate 1. Therefore, the rotation of the worm wheel 7 will drive the support rod 4 to rotate around its own axis in the through hole on the upper surface of the mounting seat 2. The rotation of the support rod 4 will cause the mounting device bracket 5 installed on its upper end and hinged to it to change its orientation in the horizontal direction. When the electric push rod 16 is started, the ejection end of the electric push rod 16 is hinged to the lower surface of the mounting device bracket 5. The bottom of the electric push rod 16 is connected to the support rod 4 through the hinge with the connecting seat 15 and the cross bar 14. When the electric push rod 16 is extended and retracted, since its two ends are respectively hinged with the mounting device bracket 5 and the support rod 4, it will push the mounting device bracket 5 to rotate around the hinge point at the upper end of the support rod 4, thereby adjusting the pitch angle of the mounting device bracket 5.
[0026] Example 2
[0027] Referring to the figure, this embodiment is based on the previous embodiment, and is different from the previous embodiment in that ventilation slots are respectively provided on both sides of the installation device bracket 5, and three groups of cooling fans 17 are fixedly connected to the outside of the ventilation slot on one side of the installation device bracket 5. Each group of cooling fans 17 is electrically connected to an external power supply. When the cooling fan 17 is started, the rotation of the cooling fan 17 will accelerate the flow of air. The external cold air is extracted by the cooling fan 17 and enters from the ventilation slot on the other side of the installation device bracket 5. After passing through the inside of the installation device bracket 5 and taking away the heat, it is discharged from the ventilation slot on the side where the cooling fan 17 is located, thereby effectively reducing the temperature inside the installation device bracket 5. A connecting slot is provided on the upper surface of the installation device bracket 5, and three groups of cooling slots are provided on the lower surface of the installation device bracket 5. The three groups of cooling slots on the lower surface of the installation device bracket 5 are conducive to the discharge of hot air from below, further promoting the dissipation of heat.
[0028] Among them, several groups of heat dissipation fins 11 are fixedly connected to the lower surface of the heat conducting plate 10, and heat is conducted to the heat dissipation fins 11 through the heat conducting plate 10. The heat dissipation fins 11 increase the heat dissipation area and improve the heat dissipation efficiency. The heat conducting plate 10 and the heat dissipation fins 11 are both made of copper with good thermal conductivity. The outer surface of the heat conducting plate 10 is fixedly connected to the inner wall of the connecting groove on the upper surface of the mounting device bracket 5. The upper surface of the heat conducting plate 10 passes through the connecting groove on the upper surface of the mounting device bracket 5 and is attached to the lower surface of the solar photovoltaic panel 12. Since the upper surface of the heat conducting plate 10 is attached to the lower surface of the solar photovoltaic panel 12, the heat generated by the solar photovoltaic panel 12 will be transferred to the heat conducting plate 10.
[0029] The working principle of this embodiment is as follows:
[0030] Since the upper surface of the heat conducting plate 10 is attached to the lower surface of the solar photovoltaic panel 12, the heat generated by the solar photovoltaic panel 12 will be transferred to the heat conducting plate 10, and the heat is conducted to the heat dissipation fins 11 through the heat conducting plate 10. The heat dissipation fins 11 increase the heat dissipation area and can dissipate the heat to the air inside the mounting device bracket 5. The three groups of heat dissipation grooves on the lower surface of the mounting device bracket 5 are conducive to the discharge of hot air from below, further promoting the dissipation of heat. When the temperature inside the mounting device bracket 5 is too high and the active heat dissipation efficiency through the heat dissipation grooves is low, the three groups of heat dissipation fans 17 installed outside the ventilation slots on one side of the mounting device bracket 5 are started. The rotation of the heat dissipation fans 17 will accelerate the flow of air. The external cold air extracted by the heat dissipation fans 17 enters from the ventilation slots on the other side of the mounting device bracket 5, takes away the heat from the inside of the mounting device bracket 5, and is discharged from the ventilation slots on the side where the heat dissipation fans 17 are located, thereby effectively reducing the temperature inside the mounting device bracket 5, so that the heat generated by the solar photovoltaic panel 12 is continuously conducted to the heat sink through the heat conducting plate 10, thereby ensuring the heat dissipation of the solar photovoltaic panel 12.
[0031] The working principle provided by the present invention is as follows: when the angle of sunlight changes and the horizontal orientation of the solar photovoltaic panel 12 needs to be adjusted, the servo motor 9 is started, and the power output end of the servo motor 9 rotates to drive the worm 8 to rotate. Since the worm 8 is engaged with the worm wheel 7, the rotation of the worm 8 will cause the worm wheel 7 to rotate, and the middle part of the worm wheel 7 is fixedly connected to the outer surface of the lower end of the support rod 4, and the lower end of the support rod 4 passes through the through hole on the upper surface of the mounting seat 2 and is rotatably connected to the upper surface of the base plate 1, so the rotation of the worm wheel 7 will drive the support rod 4 to rotate around its own axis in the through hole on the upper surface of the mounting seat 2, and the rotation of the support rod 4 will cause the mounting device installed at its upper end and hinged therewith to rotate. The mounting bracket 5 can realize the change of its orientation in the horizontal direction. When the pitch angle of the solar energy needs to be adjusted, the electric push rod 16 is started. The ejection end of the electric push rod 16 is hinged to the lower surface of the mounting equipment bracket 5. The bottom of the electric push rod 16 is connected to the support rod 4 through the hinge with the connecting seat 15 and the cross bar 14. When the electric push rod 16 is extended or retracted, since its two ends respectively form a hinge relationship with the mounting equipment bracket 5 and the support rod 4, it will push the mounting equipment bracket 5 to rotate around the hinge point at the upper end of the support rod 4 to achieve the adjustment of the pitch angle of the mounting equipment bracket 5, so that the orientation and pitch angle of the mounting equipment bracket 5 can be adjusted according to the change of the sun's angle of illumination. The solar photovoltaic panel 12 is oriented toward the direction of the strongest sunlight to obtain the best solar illumination, thereby improving the maximum power generation efficiency of the solar photovoltaic panel 12. When the solar photovoltaic panel 12 is in a high temperature environment in summer, in order to prevent the high temperature from causing a decrease in the power generation efficiency of the solar photovoltaic panel 12, the heat generated by the solar photovoltaic panel 12 will be transferred to the heat conducting plate 10. The heat is conducted to the heat dissipation fins 11 through the heat conducting plate 10. The heat dissipation fins 11 increase the heat dissipation area and can dissipate the heat to the air inside the mounting device bracket 5. The three sets of heat dissipation grooves on the lower surface of the mounting device bracket 5 are conducive to the discharge of hot air from below, further promoting the dissipation of heat. When the temperature inside the mounting device bracket 5 is too high and the active heat dissipation efficiency through the heat dissipation slots is low, the three sets of cooling fans 17 installed outside the ventilation slots on one side of the mounting device bracket 5 are started. The rotation of the cooling fans 17 will accelerate the flow of air. The external cold air drawn by the cooling fans 17 enters from the ventilation slots on the other side of the mounting device bracket 5, passes through the mounting device bracket 5 and takes away the heat, and is discharged from the ventilation slots on the side where the cooling fans 17 are located, thereby effectively reducing the temperature inside the mounting device bracket 5, so that the heat generated by the solar photovoltaic panel 12 is continuously conducted to the heat sink through the heat conducting plate 10, ensuring continuous heat dissipation of the solar photovoltaic panel 12.
