Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic equipment, and in particular to an angle-adjustable photovoltaic bracket. Background Art

[0002] Photovoltaic system is a power generation device that generates direct current when exposed to sunlight. Photovoltaic modules are almost entirely composed of thin-film solid photovoltaic cells made of semiconductor materials (such as silicon). Photovoltaic brackets are required when installing photovoltaic modules. When installing photovoltaic modules, photovoltaic modules need to be oriented in the direction where the sunlight exposure time is longer and at an angle that is relatively perpendicular to the sunlight incident angle. However, at present, photovoltaic brackets are mainly fixed, resulting in the photovoltaic modules being in a fixed position, which is not convenient for adjusting the overall position. This will affect the insufficient light exposure time and light intensity on the photovoltaic modules, resulting in insufficient charging intensity of the photovoltaic modules, affecting the normal use of the photovoltaic modules and reducing the economic benefits of the photovoltaic system.

[0003] To solve this problem, the prior art also designs a photovoltaic bracket for adjusting the installation angle of the photovoltaic module. This type of photovoltaic bracket usually adjusts the pitch angle and horizontal angle of the photovoltaic bracket through motor drive. However, after the angle adjustment is completed, it is usually locked by relying on the power-off self-locking function of the motor itself or the self-locking of the mechanical transmission part. However, not all motors can self-lock, which depends on the type of motor used and its design. AC motors usually do not self-lock because they do not have an excitation magnetic field to maintain their position. Even for those motors that can self-lock, if the motor is powered off for too long, the locking force of the motor will gradually decrease. When the motor locking force is not enough to overcome the shear force, it will not be able to maintain the self-locking state. The photovoltaic bracket usually does not need to be adjusted at night, and it is difficult to ensure the stability of the photovoltaic bracket when the motor is powered off for a long time. The self-locking of the mechanical transmission part will have the problem of a small force surface. The gravity of the entire photovoltaic bracket and the influence of the wind force will be concentrated on the contact surface of the mechanical transmission part, which will aggravate the wear of the transmission part and make it difficult to ensure stability after long-term use.

[0004] In summary, the traditional angle adjustment method of photovoltaic brackets is only applicable to small photovoltaic brackets and is difficult to be applied to large photovoltaic brackets; therefore, we propose an angle-adjustable photovoltaic bracket to solve this problem.

[0018] The beneficial effects of the present invention are:

[0019] 1. In the present invention, the angle-adjustable photovoltaic bracket is driven by the cylinder to move the lifting plate upward, and the lifting plate drives the driving motor and the driving gear to move upward, so that the lifting plate is out of contact with the inner gear ring, and the driving gear begins to mesh with the inner gear ring, and then the driving motor is started to drive the driving gear to rotate, and the driving gear drives the crossbeam to rotate by meshing with the inner gear ring, and the crossbeam drives the bracket body to rotate through the cooperation of the fixed frame, the support plate and the adjustment plate, so as to adjust the horizontal angle of the bracket body;

[0020] 2. In the present invention, the angle-adjustable photovoltaic bracket drives the connecting shaft and the driven gear to perform circular motion through the fixed frame, the driven gear rotates by meshing with the outer gear ring, and drives the rotating box to rotate through the connecting shaft. While the rotating box rotates, the two vertical plates receive centrifugal force to move away from each other and compress the two compression springs. The two vertical plates drive the horizontal plates to move upward through the corresponding connecting plates, the horizontal plates drive the turntable to move upward through the connecting columns, and the turntable drives the U-shaped plate to move upward. The U-shaped plate drives the multiple bent card plates to disengage from the card slots through the cooperation of the multiple inclined holes and the corresponding bent card plates, thereby releasing the fixation of the adjustment plate. Then, the electric push rod can be started to drive the adjustment plate to move up and down, and the adjustment plate can adjust the pitch angle of the bracket body by being hinged with the bracket body.

[0021] 3. In the present invention, the angle-adjustable photovoltaic bracket described above controls the driving motor and the electric push rod to stop running after the adjustment is completed, so that the rotating box stops rotating, and the two vertical plates are reset and approach each other under the elastic force of the compression spring, and the U-shaped plate moves downward under the action of the vertical spring, and drives the multiple bent card plates to move in the opposite direction and re-engage in the corresponding card slots, so as to fix the adjustment plate, thereby locking the pitch angle of the bracket body;

[0022] 4. In the present invention, the angle-adjustable photovoltaic bracket drives the lifting plate to move downward by starting the cylinder, so that the driving gear is disengaged from the inner gear ring, and the lifting plate is inserted into the inner gear ring. The rotation of the inner gear ring is locked by the tooth grooves provided on the outer side of the lifting plate and the cooperation with the inner gear ring, and the larger force-bearing surface can ensure stability;

[0023] 5. In the present invention, the angle-adjustable photovoltaic bracket can drive the blades to move and the mounting column to move by the wind force through the wind locking device when encountering strong wind conditions. The mounting column drives the limit plate to move through the column, so that the edge of the limit plate exceeds the inner ring of the retaining ring, so that the upward movement of the limit plate can be limited by the retaining ring, thereby limiting the upward movement of the lifting plate, thereby avoiding the angle adjustment of the photovoltaic bracket under the condition of strong wind force, so as to avoid the wind force increasing the load of the adjustment drive mechanism, thereby ensuring the stability of the adjustment process;

[0024] 6. In the present invention, the angle-adjustable photovoltaic bracket can lock the horizontal angle of the photovoltaic bracket by means of a lifting plate, and can lock the pitch angle of the photovoltaic bracket by means of the cooperation of a U-shaped plate, a bending pallet and a rotating box. The locking method has a large contact surface, so that stability can be maintained for a long time, and the pitch angle can be automatically unlocked when the horizontal angle of the photovoltaic bracket is adjusted, so as to facilitate multi-dimensional adjustment at the same time.
