Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic frames, and specifically relates to a solar photovoltaic frame. Background Art

[0002] Solar photovoltaic frame is a structural frame used to support and fix solar photovoltaic panels. Since solar photovoltaic panels usually need to be exposed to the natural environment for a long time, the photovoltaic frame must have sufficient strength and durability to ensure the long-term stable operation of the solar photovoltaic system.

[0003] Existing solar photovoltaic frames are usually made of high-strength aluminum alloy materials, which are lightweight, strong, and corrosion-resistant. For example, China's patented solar photovoltaic frame aluminum profile, announcement number: CN20889073U, reduces the difficulty of installing photovoltaic panels by setting components such as horizontal extension plates, vertical extension plates, and horizontal clamps on the main body of the aluminum alloy profile. At present, during installation, due to the large paving area of ​​photovoltaic panels in some areas, for the maintenance or installation of photovoltaic panels in the depth, the installation workers need to step on the photovoltaic frame to reach the installation and maintenance point. The horizontal clamp at the upper end of the existing photovoltaic frame is too narrow and the photovoltaic panel is assembled. The rear horizontal clamp is tightly attached to the photovoltaic panel. Although the photovoltaic frame has a certain degree of pressure resistance, due to negligence in operation, manual stepping on the photovoltaic frame will inevitably leave hidden cracks on the photovoltaic panel. Such hidden cracks are difficult to find and cannot be repaired and replaced in time. We know that hidden cracks refer to small cracks in the battery cell. Hidden cracks in the battery cell will accelerate the attenuation of the battery cell power and affect the normal service life of the component. It may also expand under mechanical loads, resulting in open circuit damage and hot spot effects. Therefore, for the installation or maintenance of photovoltaic panels with a large depth, how to avoid hidden cracks caused by improper manual operation is an issue that needs attention.

[0020] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0021] Specific embodiment 1: Please refer to Figure 1-3 A solar photovoltaic frame comprises: a frame body 1 and a pedal 2, wherein the pedal 2 is slidably connected to the frame body 1, the length of the pedal 2 is less than the length of the frame body 1, and the height of the pedal 2 is not greater than the height of the frame body 1. When in use, when workers are installing or repairing photovoltaic panels in depth, the pedal 2 can provide workers with a stepping point to avoid workers directly stepping on the frame body and the photovoltaic panel body, thereby reducing the occurrence of damages caused by installation or maintenance operation errors; in addition, in specific applications, the number of pedals 2 can be increased or decreased depending on the specific situation.

[0022] Specifically, the frame body 1 is an integrated structure consisting of a lower horizontal baffle 11, a side panel 12, a middle horizontal baffle 13, an upper horizontal baffle 14, and an extension plate 15. The lower horizontal baffle 11 is arranged at the lower end of the side panel 12, the middle horizontal baffle 13 is arranged at the top of the side panel 12, and the upper horizontal baffle 14 is arranged on the upper side of the middle horizontal baffle 13 through the extension plate 15. The thickness of the side panel 12 is greater than the thickness of the extension plate 15 to improve the compressive resistance of the frame body 1. A slide groove 121 is opened on the outer end surface of the side panel 12, and the opening direction of the slide groove 121 is consistent with the length direction of the side panel 12 body.

[0023] The pedal 2 includes a top plate 22 and a support frame, the top plate 22 is arranged on the support frame, and the upper end surface of the top plate 22 is also provided with a plurality of anti-slip grooves;

[0024] The support frame includes a support plate 21 and a slide plate 23, wherein the slide plate 23 is arranged at the lower part of the support plate 21, and the top plate 22 is arranged at the upper end of the support plate 21, and the support plate 21 and the top plate 22 form a T-shaped structure; after assembly, the slide plate 23 is at least partially embedded in the slide groove 121, the main end surface of the support plate 21 is parallel to the main end surface of the side plate 12, and the top plate 22 is located on the upper side of the upper cross baffle 14. In this embodiment, the slide plate 23 cooperates with the slide groove 121 to provide a stable fulcrum for the pedal 2 body. At the same time, the slide plate 23 and the side plate 12 are slidably connected, and the pedal 2 is pushed to flexibly change the position of the pedal 2 on the frame body 1. When a worker steps on the top plate 22, since the top plate 22 is located on the upper side of the upper cross baffle 14, the top plate 22 is compressed but will not squeeze the upper cross baffle 14, thereby avoiding the occurrence of damage to the photovoltaic panel caused by the worker directly stepping on the frame body and the photovoltaic panel body.

[0025] In order to further provide stable support, the width of the top plate 22 is greater than the width of the upper cross baffle 14; in addition, there are two slide plates 23, which are distributed from top to bottom at the lower part of the support plate 21, and two slide grooves 121 are also provided, and the slide plates 23 are arranged corresponding to the slide grooves 121; the pedal 2 is an integrated structure, so that the structural rigidity is stronger.

[0026] In other preferred embodiments, the support plate 21 and the top plate 22 can be detachably connected, such as plug-in, so that during implementation, the support frame can be installed on the frame body 1 in advance. When maintenance or installation is required, the top plate can be installed at the corresponding position to cooperate with the work, which increases the flexibility of the work.

[0027] In other preferred embodiments, in order to improve the load-bearing capacity of the pedal 2 and further reduce the impact on the frame body 1 , the lower end surface of the support plate 21 is flush with the lower end surface of the lower transverse baffle 11 .

[0028] See also Figure 3 This is an implementation method of the pedal 2 between photovoltaic panels at adjacent positions. The top plate 22 and the support plate 21 are embedded in the slide grooves at corresponding positions through the slide plate 23 and are erected between the photovoltaic panels at adjacent positions. Under the support of the side plates 12 of the photovoltaic panels at adjacent positions, the top plate 22 is always located on the upper side of the photovoltaic panels, providing stable, reliable and movable foot support for installation or maintenance.

[0029] Through the technical solution, a pedal is arranged on the frame body, the pedal can be slidably connected to the frame body, and the top plate of the pedal is always located on the upper side of the frame body. When a worker steps on the top plate, since the top plate is located on the upper side of the upper cross baffle, the top plate is compressed but will not squeeze the upper cross baffle, thereby avoiding the situation where the worker directly steps on the frame body and the photovoltaic panel body to cause damage to the photovoltaic panel.

[0030] Example 2: Please refer to Figure 4 , which is different from the first embodiment, in order to provide a more stable supporting force for the top plate 22, the pedal 2 includes a top plate 22 and two sets of support frames, the two sets of support frames are fixedly arranged at the lower end of the top plate 22, the support frames include a support plate 21 and a slide plate 23, and the main planes of the two support plates 21 are parallel to each other. That is to say, compared with the first embodiment, the single-plate support on the lower side of the top plate 22 is changed to a double-plate support, so that the top plate 22 is not easy to shake after being subjected to force, further avoiding the situation of accidental stepping due to operational errors.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
