[0002] Photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. Photovoltaic brackets include fixed, adjustable or tracking types. Among them, tracking photovoltaic brackets can use solar trackers to make the brackets automatically rotate following the changes in light angle, which is beneficial for making the sunlight shine directly on the solar panels. Compared with fixed photovoltaic brackets, it can increase power generation by 20%-25%, with excellent performance.
[0003] The solar tracker is mainly composed of a sensor, an azimuth tracking mechanism, an altitude tracking mechanism and an automatic control device; the Chinese patent application publication number CN116526948A discloses a photovoltaic tracking bracket drive device, which is essentially also an altitude tracking mechanism, including a column, a main shaft movably connected to the column, a first gear plate connected to the main shaft, a second gear plate connected to the column, a roller chain connected to the column, a transmission assembly connected to the roller chain, and a motor connected to the transmission assembly, the roller chain is arranged between the first gear plate and the second gear plate, a connecting rod is connected between the first gear plate and the second gear plate, and the roller chain is respectively engaged with the first gear plate and the second gear plate.
[0004] With respect to the above-mentioned related technical solutions, the solar panel is usually fixed on the main shaft. In order to keep the altitude angle of the solar panel fixed, the motor needs to be always in a powered-on state so that the first gear and the second gear are protected and engaged and fixed. Although the electricity generated by the solar panel can always power the motor, the electricity consumed for continuous power supply to the motor is also relatively large, which indirectly leads to a decrease in the effective power generation efficiency of the solar panel, which needs to be improved. Summary of the invention
[0005] Based on this, the present application provides a trackable solar photovoltaic bracket, which can keep the altitude angle of the solar panel fixed when the drive motor is powered off, thereby improving the effective power generation efficiency of the solar panel.
[0006] The present application provides a trackable solar photovoltaic bracket adopting the following technical solutions:
[0007] A trackable solar photovoltaic support, comprising a main beam, a secondary beam, an auxiliary column, at least one supporting column and at least one fixed beam; wherein the supporting column and the auxiliary column are both fixed to a base carrier, a rotating mechanism is provided at the top of the supporting column, and the main beam is fixedly mounted on the rotating mechanism;
[0008] The fixed beam is fixedly mounted on the main beam and is used to install the solar panel; the auxiliary beam is slidably connected to the fixed beam, and the sliding direction of the auxiliary beam is perpendicular to the length direction of the auxiliary beam; an adjustment mechanism for adjusting the height angle of the solar panel is provided between the auxiliary column and the auxiliary beam; wherein,
[0009] The adjustment mechanism includes a lifting rod connected to the auxiliary beam by sliding and rotation, a rotating rod connected to the auxiliary column by rotation, and a driving motor for driving the rotating rod to rotate. A spiral extension is provided on the outer peripheral side of the rotating rod, and the distance between the outer edge of the spiral extension and the central axis of the rotating rod gradually decreases from one end of the rotating rod to the other end.
[0010] The lifting rod is equipped with a rolling member, and a sliding groove is provided on the outer circumference of the rolling member; the rolling member naturally rests against the spiral extension under the action of gravity, and the spiral extension is partially located inside the sliding groove; a guide component is also provided between the lifting rod and the auxiliary column, which is used to move the lifting rod in the vertical direction.
[0011] By adopting the above-mentioned technical solution, a fixed beam is set up to fix the solar panel, and the rotating mechanism between the main beam and the supporting column can be used as a rotating base. By controlling the action of the adjustment mechanism, the solar panel can be rotated around the rotating mechanism, thereby changing the altitude angle of the solar panel so that the sunlight can directly shine on the solar panel.
[0012] Specifically, the lifting rod of the present application can only be lifted up and down under the guidance of the guide assembly, and the lifting rod can naturally rest against the spiral extension under the action of its own gravity. Since the distance from the outer edge of the spiral extension to the central axis of the rotating rod is constantly changing, when the drive motor rotates, the spiral extension can gradually force the lifting rod to lift up and down, thereby promoting the rotation of the fixed beam movably connected to the lifting rod, thereby realizing the angle adjustment of the solar panel; through the cooperation of the sliding slot and the spiral extension, after the height angle of the solar panel is fixed, the drive motor is in a power-off state, and the gravity acting on the solar panel and the lifting rod acts vertically on the rotating rod, which can limit the natural rotation of the rotating rod, thereby keeping the height angle of the solar panel fixed, which is beneficial to improving the effective power generation efficiency of the solar panel and increasing the effective amount of electricity generated by the solar panel.
[0013] Optionally, the guide assembly includes a sliding sleeve vertically slidably mounted on the lifting rod and an inserted rod fixed to the side of the sliding sleeve, and the inserted rod is movably inserted in the auxiliary column; the cross-sectional shape of the inserted rod is rectangular, and the moving direction of the inserted rod is set in the same direction as the horizontal direction. When the lifting rod moves upward, the inserted rod moves horizontally in a direction close to the auxiliary column.
[0014] By adopting the above-mentioned technical solution, the sliding sleeve is horizontally slidably inserted into the auxiliary column through the outer insertion rod, so that the direction of the sliding sleeve remains unchanged when the sliding sleeve moves horizontally; at this time, when the lifting rod movably sleeved on the sliding sleeve moves driven by the spiral extension part, the moving direction of the lifting rod can always be kept vertical, ensuring that the lifting rod can steadily push the solar panel to rotate.
[0015] Optionally, an end of the plug-in rod away from the sliding sleeve is provided with an integrally formed cylindrical portion; a rotating seat is rotatably embedded in the auxiliary column, and the rotating seat is provided with a movable slot for the cylindrical portion to match and pass through, and the movable slot is coaxially arranged with the rotating seat;
[0016] A spiral groove is provided on the outer circumferential surface of the cylindrical part, and a spiral protrusion is provided on the inner circumferential wall of the movable slot that is slidably matched with the spiral groove. The cooperation between the spiral groove and the spiral protrusion can force the rotating seat to rotate circumferentially; a clamping mechanism is also provided on the outer circumferential side of the rotating seat. When in use, the rotating seat is kept in position by the clamping mechanism.
[0017] By adopting the above-mentioned technical solution, when the driving motor runs and drives the lifting rod to move up and down, the cylindrical part at the end of the plug-in rod can translate axially in the movable slot, and the rotating seat can be rotated through the cooperation of the spiral groove and the spiral protrusion; when the solar panel is adjusted to the required height angle, the clamping mechanism can limit the rotation of the rotating seat, thereby limiting the horizontal movement of the cylindrical part and the plug-in rod, thereby further limiting the natural rotation of the rotating rod, so that the height angle of the solar panel remains fixed, and the driving motor does not need to be energized to maintain it, thereby improving the effective power generation efficiency of the solar panel.
[0018] Optionally, the clamping mechanism includes a first tension spring and two movable swing arms, wherein the two movable swing arms are respectively hinged to the auxiliary pillars, the two movable swing arms are symmetrically arranged on the outer side of the rotating seat, and a damping pad is fixed on the side of each movable swing arm close to the rotating seat;
[0019] The first tension spring is connected between the two movable swing arms. The first tension spring is always in a stretched state, and can force the two damping pads to approach each other and press against the rotating seat together.
[0020] By adopting the above-mentioned technical solution, when the height angle of the solar panel remains fixed and the drive motor is in a power-off state, the elastic tension generated by the first tension spring acting between the two movable swing arms can make the two damping pads move toward each other and jointly clamp the rotating seat, thereby smoothly limiting the movement of the plug-in rod and the rotation of the rotating rod.
[0021] Optionally, the clamping mechanism also includes an electric push rod and two articulated arms, the two articulated arms are respectively articulated to two movable swing arms, and one end of each articulated arm away from the movable swing arm is rotatably connected to a connecting component; the electric push rod is fixed to the auxiliary column, and the movable end of the electric push rod is fixedly connected to the connecting component.
[0022] By adopting the above-mentioned technical solution, by controlling the action of the electric push rod to drive the connection component to move, the two articulated arms rotatably connected to the connection component can be rotated toward each other, thereby forcing the two movable swing arms to move away from each other, so that the damping pad can be smoothly separated from the rotating seat, so as to facilitate the smooth rotation of the rotating seat and the smooth movement of the plug-in rod, thereby facilitating the smooth lifting and lowering of the lifting rod and the smooth rotation of the solar panel.
[0023] Optionally, it also includes a sensor module for controlling the operation of the electric push rod and the drive motor. When the sensor module detects a change in the light altitude angle, the electric push rod is in action, and then the drive motor is powered on; when the solar panel rotates to an angle directly opposite the light, the electric push rod and the drive motor are both in a power-off state.
[0024] By adopting the above-mentioned technical solution, the sensor module is set to detect the altitude angle of light. When it is measured that the angle of sunlight shining on the solar panel is skewed, the sensor module first controls the action of the electric push rod to release the rotation restriction on the rotating seat, and then controls the drive motor to drive the rotating rod to move, so as to smoothly adjust the angle of the solar panel in real time.
[0025] Optionally, the rotating seat is partially exposed from the auxiliary column and is fixed with a winding drum; a steel rope is provided between the winding drum and the fixed beam, one end of the steel rope is fixedly connected to the winding drum, and the other end is elastically connected to the fixed beam through a second tension spring. When the lifting rod drives the fixed beam to move upward, the winding drum rotates and gradually unwinds the steel rope.
[0026] By adopting the above-mentioned technical solution, by arranging a steel rope to connect it between the winding drum and the fixed beam, the stability and wind load resistance of the solar panel can be improved after the installation, so that the photovoltaic bracket can maintain a good service life; when the lifting rod drives the fixed beam to move upward, the distance between the fixed beam and the rotating seat gradually increases. At this time, the movement of the cylindrical part in the movable slot can automatically drive the collecting drum to unwind the steel rope, which can ensure the stability of the solar panel while weakening the hard pulling force of the steel rope on the fixed beam, thereby reducing the possibility of tensile deformation of the fixed beam.
[0027] Optionally, multiple supporting columns are provided, and connecting columns are connected between adjacent supporting columns; a first diagonal bracing mechanism is provided between the connecting columns and the fixed beam, and the first diagonal bracing mechanism includes a fixed column fixed to the connecting column and a movable column movably plugged into the fixed column, an end of the movable column away from the fixed column is hinged and slidably connected to the fixed beam, and the sliding direction of the movable column is the same as the length direction of the fixed beam.
[0028] By adopting the above technical solution, the setting of the first diagonal bracing mechanism can improve the connection stability between the supporting column and the fixed beam, thereby further improving the stability and wind load resistance of the solar panel after installation, so that the photovoltaic bracket maintains a good service life.
[0029] Optionally, a second diagonal bracing mechanism is provided between the fixed column and the fixed beam, and the second diagonal bracing mechanism includes two movably connected hinged columns, one of which is hinged to the fixed column, and the other is hinged to the fixed beam.
[0030] By adopting the above technical solution, by setting a second diagonal bracing mechanism and fixing it between the fixed column and the fixed beam, a stable triangular support structure can be formed, thereby further improving the stability of the fixed beam, thereby further improving the stability and wind load resistance of the solar panel after installation.
[0031] Optionally, the rotating mechanism includes two bearings and two sleeves, and mounting grooves are respectively provided on opposite sides of the two bearings, and the two mounting grooves together form an installation space for fixing the main beam; the outer arc surface of the bearing is provided with a circumferentially extending annular groove, and the two sleeves are connected to each other and rotate together in the two annular grooves; the sleeves are fixedly connected to the supporting column.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:
[0034] 1. By setting a driving motor to drive the rotating rod to rotate, the abutment cooperation between the spiral extension and the rolling element can force the lifting rod to move up and down, so as to achieve the angle adjustment of the solar panel; and, by the limit cooperation between the movable card slot and the spiral extension, the natural rotation of the rotating rod can be limited, so that the height angle of the solar panel can be kept fixed, thereby improving the effective power generation efficiency of the solar panel;
[0035] 2.

The steel rope 33 in this embodiment is always in a taut state, which is conducive to improving the stability of the solar panel after installation, and when the lifting rod 71 moves upward and drives the fixed beam 5 and the solar panel to flip upward, the cylindrical part 751 automatically forces the rotating seat 31 and the winding drum 32 to rotate, and the winding drum 32 can gradually unwind the steel rope 33, which can ensure the stability of the solar panel while reducing the hard pulling force of the steel rope 33 on the fixed beam 5, and reduce the possibility of the fixed beam 5 being deformed by tension.
[0065] In addition, the photovoltaic bracket of the present application also includes a sensor module (not shown in the figure) for controlling the operation of the electric push rod 83 and the drive motor 73. The sensor module is usually installed on the side of the solar panel to measure the altitude angle of the light. When the sensor module detects that the altitude angle of the light has changed, the electric push rod 83 is firstly powered on, and the electric push rod 83 is controlled to move to release the rotation restriction of the rotating seat 31; secondly, the drive motor 73 is powered on, and the drive motor 73 is controlled to be powered on to drive the lifting rod 71 up and down, so that the fixed beam 5 can rotate around the rotating mechanism 6, thereby changing the altitude angle of the solar panel; finally, when the solar panel rotates to an angle directly opposite to the light, the sensor module can make the electric push rod 83 and the drive motor 73 both in the power-off state, which can save the power generated by the solar panel and improve the effective power generation efficiency of the solar panel.
[0066] The implementation principle of a trackable solar photovoltaic bracket in the embodiment of the present application is:
[0067] The solar panel of the present application is installed on a photovoltaic bracket, and the sensor module can monitor the altitude angle of light in real time, and can automatically adjust the solar panel to an angle directly opposite to the light, thereby increasing the power generation of the solar panel. After the angle of the solar panel is kept fixed, the drive motor 73 is turned off, and the rolling element 711 can naturally lean against the spiral extension 721 under the action of its own gravity and the lifting rod 71. At this time, the gravity exerted on the solar panel and the lifting rod 71 acts vertically on the rotating rod 72, which can limit the natural rotation of the rotating rod 72, and further limit the rotation of the solar panel. Therefore, when the drive motor 73 is powered off, the altitude angle of the solar panel can still be kept fixed, which is conducive to increasing the effective amount of electricity generated by the solar panel and improving the effective power generation efficiency of the solar panel.
[0068] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
