Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic module frame mounting components, and in particular to a fixing component for short C-frames and purlins. Background Technology

[0002] See Figure 4 As shown, some of the frame bottoms extend to form horizontal panels. These horizontal panels are fixed to the purlins in the following two ways: 1. Drill mounting holes on the extension end. Bolts pass through the mounting holes on the extension end and the pre-drilled holes on the purlin to fix the frame to the purlin.

[0003] 2. Use fixing components to secure the frame to the purlin. The fixing components may be used by pressing down on the top of the frame or only on the bottom extension of the frame. This fixing method limits one side of the frame.

[0004] During actual installation, the purlins on the two spans of the photovoltaic support beams are 4-4.5 meters apart, causing them to bend along the east-west direction. The left-right and top-bottom spacing and orientation of the module frames need to be adjusted during and after installation. Because the fixing components only limit movement on one side of the frame, the fixing components can easily separate from the frame, leading to installation failure. In severe cases, this can cause the photovoltaic panels to fall to the ground and damage them. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fixing component for short C-frames and purlins, which can prevent the frame from losing contact with the pressure plate during installation and adjustment after installation, improve the frame installation firmness, and the fixing component is low in cost and easy to install.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A fixing component for a short C-frame and purlin includes a fixing component body, the fixing component body including a base plate and a pressure plate, one side edge of the base plate extending upward to form a first limiting plate, the frame being placed on the base plate, one side edge of the pressure plate extending upward to form a second limiting plate, and the two sides of the frame respectively abutting against one side of the first limiting plate and one side of the second limiting plate. The bottom extension of the frame is located between the pressure plate and the base plate; The base plate, the pressure plate, and the purlins are fixedly connected by bolts.

[0007] In a preferred embodiment, the present invention can be further configured such that a support block is integrally formed at the bottom of the pressure plate away from the frame; The height of the support block is equal to the height of the bottom extension end in the frame.

[0008] In a preferred embodiment, the present invention can be further configured such that: the other side edge of the base plate extends upward to form a third limiting plate; The portion of the third limiting plate near the pressure plate is machined into a first inclined surface; The portion of the pressure plate near the third limiting plate is machined into a second inclined surface; The first inclined surface is in contact with the second inclined surface.

[0009] In a preferred embodiment, the present invention can be further configured such that a first through hole is provided on the pressure plate; The base plate has a waist-shaped hole; The bolt passes through the first through hole and the waist-shaped hole.

[0010] In a preferred embodiment, the present invention can be further configured such that the end of the support block near the base plate is rounded.

[0011] In summary, this utility model has at least one of the following beneficial technical effects: 1. The system includes a base plate and a pressure plate. The base plate has a first limiting plate on top, and the pressure plate has a second limiting plate on top. The frame is placed between the first and second limiting plates, with both sides of the frame abutting against one side of the first and second limiting plates, respectively. The first and second limiting plates limit the sides of the frame, preventing it from detaching from the purlin after installation, thus improving the frame's installation stability. The fixing components are also low-cost and easy to install.

[0012] 2. By setting a support block at the bottom of the pressure plate, the pressure plate remains horizontal when it is fixed by bolts, thereby ensuring that one side of the second limiting plate is always in contact with one side of the frame.

[0013] 3. By providing a first inclined surface on one side of the third limiting plate and a second inclined surface on the other side of the pressure plate, the first inclined surface is tilted away from the frame, which makes it convenient for the operator to quickly place the pressure plate. As the pressure plate gradually approaches the bottom plate, the force exerted by the pressure plate on the frame becomes greater and greater, further strengthening the fixation of the frame.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0017] Reference Figures 1-3 As shown, this utility model discloses a fixing component 1 for short C-frames and purlins, including a fixing component 1 body. The fixing component 1 body includes a base plate 11 and a pressure plate 12.

[0018] The pressure plate 12 has a first through hole 4, and the base plate 11 has a waist-shaped hole. The bolt passes through the first through hole 4, the waist-shaped hole, and the pre-set hole on the purlin. The first through hole 4 is located directly above the waist-shaped hole.

[0019] In this embodiment, the first through hole 4 is a circular hole, an oblong hole, or a through hole of other shapes. When installing the fixing component 1, the bolt passes through the first through hole 4 and the hole in the base plate for locking.

[0020] One side edge of the base plate 11 extends upward to form a first limiting plate 13, and the other side edge of the base plate 11 extends upward to form a third limiting plate 3. The portion of the third limiting plate 3 near the pressure plate 12 is processed into a first inclined surface 31.

[0021] One edge of the pressure plate 12 extends upward to form a second limiting plate 14. The portion of the pressure plate 12 near the third limiting plate 3 is machined into a second inclined surface 32. The first inclined surface 31 is parallel to the second inclined surface 32. After installation, the first inclined surface 31 and the second inclined surface 32 are in contact.

[0022] A support block 2 is integrally formed at the bottom of the pressure plate 12, away from the frame. The height of the support block 2 is equal to the height of the bottom extension end in the frame, making the top surface of the pressure plate 12 parallel to the top surface of the base plate 11. The end of the support block 2 near the base plate 11 is rounded.

[0023] The bolt is located between the support block 2 and the frame.

[0024] During installation, the assembled frame assembly is first placed on the two purlins. Then, the operator installs the fixing component 1 onto the frame, with one side of the frame abutting against one side of the first limiting plate 13. Because the base plate 11 has a slotted hole, the pressure plate 12 can be tilted when only the bolts are passed through the pressure plate 12 and the base plate 11, without tightening the nuts on the bolts. This means the second limiting plate 14 on the pressure plate 12 is not in contact with the other side of the frame assembly. This allows the operator to easily move the base plate 11 and the pressure plate 12.

[0025] Move the fixing component 1 along the length of the horizontal plate in the frame. When the fixing component 1 is moved to the appropriate position, the operator lifts the frame component so that the bolt on the fixing component 1 passes through the preset hole on the purlin.

[0026] Then the pressure plate 12 is placed in place. At this time, one side of the second limiting plate 14 is in contact with the other side of the frame, and the first inclined surface 31 is in contact with the second inclined surface 32.

[0027] Finally, screw on the nut to fix the position of the fixing component 1.

[0028] It is particularly noteworthy that when the nuts on the bolts are not fully tightened, the top edge of the second inclined surface 32 is slightly higher than the top edge of the first inclined surface 31, and there is a slight gap between the bottom of the support block 2 and the top of the pressure plate 12.

[0029] After the nuts are tightened, the height of the top edge of the first inclined surface 31 is equal to the height of the top edge of the second inclined surface 32, and the bottom of the support block 2 is in contact with the top of the pressure plate 12. At the same time, one side of the second limiting plate 14 is in contact with one side of the frame.

[0030] The pressure plate 12, the second limiting plate 14 and the third limiting plate 3 on it form a horizontal force on the frame, further limiting the position of the frame.

[0031] To facilitate the operator's placement of the pressure plate 12, the pressure plate 12 is placed between the third limiting plate 3 and the frame by pressing.

[0032] After the pressure plate 12 is placed in place, the top surface of the third limiting plate 3 is flush with the top surface of the pressure plate 12.

[0033] The bottom extension of the frame is located between the pressure plate 12 and the base plate 11, and the top and bottom sides of the bottom extension of the frame are respectively attached to the bottom of the pressure plate 12 and the top of the base plate 11.

[0034] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
