Description

Technical Field

[0001] This application relates to the field of photovoltaic module installation technology, and in particular to a device and method for laying photovoltaic modules in mountainous areas. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that generates direct current (DC) when exposed to sunlight. It consists of thin, solid photovoltaic cells made almost entirely of semiconductor materials, such as silicon.

[0003] To ensure the photovoltaic (PV) panels function optimally, we install them in mountainous areas. However, mountainous terrain is complex, and to maintain optimal panel condition, we typically use adjustment mechanisms. However, strong winds in mountainous areas can cause both the adjustment mechanism and the panels to sway simultaneously, impacting the lifespan of both the installation and the panels, especially when adjusting the panels at multiple angles and heights.

[0004] To address this, we designed a highly efficient adjustment mechanism that allows the photovoltaic panel to deflect stably to the left and right, forward and backward, and also to be adjusted up and down. Even after adjustment, the photovoltaic panel and its structure can remain relatively stable in strong winds and will not sway easily, thereby improving the service life of the device. Furthermore, this highly efficient adjustment mechanism has a compact structure, occupies little ground space, has low manufacturing cost, and is easy to maintain. Summary of the Invention

[0005] The main purpose of this application is to provide a device and method for laying photovoltaic modules in mountainous areas, so as to solve the problem that the existing multi-angle height adjustment mechanism is prone to swaying itself and the photovoltaic panel when encountering strong winds, which reduces its service life.

[0015] A method for laying photovoltaic modules in mountainous areas, using the aforementioned mountainous photovoltaic module laying device, is characterized by comprising: S1: First, install the support rod at the preset position in the mountain to complete the installation of the device at the preset position in the mountain. S2: Install the photovoltaic panels of the photovoltaic module on the top of the horizontal plate to complete the installation of the photovoltaic module and photovoltaic panels; S3: Start the second electric telescopic rod to make the second bevel tooth mesh with the first bevel tooth, then start the motor to make the threaded rod, sliding column, ring sleeve, third rotating column and first rotating column rotate in a circle, so that the photovoltaic module deflects back and forth to a preset angle.

S4: After completing S, hold the photovoltaic panel of the photovoltaic module by hand, and then start the second electric telescopic rod to retract so that the second bevel tooth and the first bevel tooth are no longer engaged. Then start the motor so that only the sliding plate moves up or down. At this time, adjust the photovoltaic panel of the photovoltaic module to the required height, and then start the second electric telescopic rod to keep the second bevel tooth and the first bevel tooth engaged, forming a self-locking state, so that the photovoltaic panel of the photovoltaic module remains in a stable state for operation.

[0016] Compared with the prior art, the beneficial effects of the present invention include: The set stable up-and-down moving mechanism can stably adjust the height of the photovoltaic panel of the photovoltaic module. The up-and-down movement is achieved by threads to make the height adjustment tight.

After adjusting the height of the photovoltaic panel and the two deflection angles of the photovoltaic module, the self-locking of the motor of the stable up-and-down moving mechanism can make the device more stable, thereby greatly improving the lifespan of the device. The device's adjustment mechanisms are all housed within a work box consisting of a sliding sleeve plate and a protective plate, which occupies a relatively small area and is easy to use; The device uses only one motor, which makes the device cost-effective and easy to maintain.

[0036] Methods for installing photovoltaic modules in mountainous areas include: S1: First, install the support rod 29 at the preset position in the mountain to complete the installation of the device at the preset position in the mountain. S2: Install the photovoltaic panel of photovoltaic module 5 on the top of the horizontal plate 7 to complete the installation of the photovoltaic panel of photovoltaic module 5; S3: Start the second electric telescopic rod 39 so that the second bevel tooth 34 and the first bevel tooth 20 mesh with each other. Then start the motor 31 so that the threaded rod 24, the sliding column 36, the ring sleeve 35, the third rotating column 19, and the first rotating column 9 rotate in a circle, thereby causing the photovoltaic module 5 to deflect back and forth to a preset angle. After deflecting back and forth to the preset angle, start the first electric telescopic rod 15 so that the rack 14 and the first gear 17 mesh with each other, thereby causing the photovoltaic panel of the photovoltaic module 5 to deflect back and forth to the preset angle. S4: After completing S3, hold the photovoltaic panel of photovoltaic module 5 by hand, and then start the second electric telescopic rod 39 to retract so that the second bevel tooth 34 and the first bevel tooth 20 are no longer engaged. Then start the motor 31 so that only the sliding plate 1 moves up or down. At this time, adjust the photovoltaic panel of photovoltaic module 5 to the required height, and then start the second electric telescopic rod 39 again so that the second bevel tooth 34 and the first bevel tooth 20 remain engaged, forming a self-locking state, so that the photovoltaic panel of photovoltaic module 5 remains in a stable state for operation.

[0037] In specific implementation, firstly, a predetermined installation location is selected, ensuring that the extension plate 32 of the support rod 29 is placed relatively evenly on the mountainous ground. Then, the device is installed at the predetermined location on the mountainous ground using ground bolts passing through the mounting holes 33. Next, the photovoltaic panel of the photovoltaic module 5 is installed on the top of the horizontal plate 7 using screws and other components. The second electric telescopic rod 39 is activated via the control button 22 on the controller 3, causing the second bevel tooth 34 to mesh with the first bevel tooth 20. Then, the motor 31 is activated, causing the threaded rod 24, sliding column 36, circular sleeve 35, third rotating column 19, and first rotating column 9 to rotate circumferentially, thereby causing the photovoltaic module 5 to deflect back and forth to a predetermined angle. After setting the preset angle, the first electric telescopic rod 15 is activated, causing the rack 14 and the first gear 17 to mesh, thus causing the photovoltaic panel of the photovoltaic module 5 to deflect back and forth to the preset angle. Then, while holding the photovoltaic panel of the photovoltaic module 5, the second electric telescopic rod 39 retracts, causing the second bevel gear 34 and the first bevel gear 20 to disengage. The motor 31 is then activated, causing only the sliding plate 1 to rise or fall. At this time, the photovoltaic panel of the photovoltaic module 5 is adjusted to the required height. Then, the second electric telescopic rod 39 is activated again, keeping the second bevel gear 34 and the first bevel gear 20 engaged, forming a self-locking state, so that the photovoltaic panel of the photovoltaic module 5 remains stable during operation. At this time, the operating mechanism is within the working space formed by the sliding plate 1 and the protective plate 2, preventing damage to the operating mechanism.
