Description

Technical Field

[0001] This application relates to the field of photovoltaic panel installation technology, and in particular to a photovoltaic panel stabilizing fastener. Background Technology

[0002] A photovoltaic (PV) panel is a panel that converts solar energy into electrical energy. When using PV panels, they are often suspended in open areas using mounting frames to maximize the conversion of solar energy. To prevent the PV panels from falling and breaking due to accidental contact or other reasons, clips are used during the installation process to securely fasten the edges of the PV panels to the mounting frames.

[0003] In existing technologies, most photovoltaic (PV) panel fasteners simply use a clamping structure to hold the edge of the PV panel to the frame on the mounting bracket, and then use bolts to tighten the two. However, due to factors such as strong winds or impacts, the PV panel itself will rub against the mounting bracket when under stress. While the above structure can achieve a stable installation of the PV panel, the large area of ​​the clamped PV panel inevitably leads to significant wear and tear on the PV panel. Therefore, there is still room for improvement in existing PV panel technologies. Utility Model Content

[0004] In order to solve the problems of structural wear caused by collisions or strong winds when photovoltaic panels are fixed on the mounting frame in the prior art, and to make innovative improvements to the structure of the fasteners for photovoltaic panel installation, this application provides a photovoltaic panel stabilizing fastener.

[0005] The photovoltaic panel stabilizing fastener provided in this application adopts the following technical solution:

[0006] A photovoltaic panel stabilizing fastener includes a mounting frame at the bottom of the photovoltaic panel, with a gap between the mounting frame and the bottom side of the photovoltaic panel. The fastener includes a pressure plate and a snap-on plate detachably mounted on the pressure plate. The pressure plate rests against the bottom of the mounting frame, and the snap-on plate is positioned in the gap between the mounting frame and the photovoltaic panel. A through hole is formed in the pressure plate, and a second through hole, coinciding with one of the first through holes in the pressure plate, is formed in the snap-on plate. A bolt passes through both the first and second through holes, and a nut for clamping the mounting frame is threaded onto the bolt. Several baffles are vertically arranged on the pressure plate, and these baffles abut against the side of the photovoltaic panel.

[0007] Optionally, the pressure plate has two through holes symmetrically formed along its length to connect two adjacent photovoltaic panels respectively, and several baffles are located in the middle of the pressure plate and on the same vertical plane.

[0008] Optionally, two baffles are symmetrically connected on the pressure plate, and both baffles are bent upward from a portion of the pressure plate, with the inner sides of the two baffles respectively abutting against two adjacent photovoltaic panels.

[0009] Optionally, the through hole is an oblong hole extending along the length of the pressure plate, and the bolt is clearance-fitted with the oblong hole to achieve sliding adjustment.

[0010] Optionally, the buckle plate may also have a baffle extending vertically on the side away from the pressure plate for laterally positioning the buckle plate, the baffle abutting against the inner side of the mounting frame on the side facing the buckle plate.

[0011] Optionally, the buckle plate includes protrusions at both ends and a recess between the two protrusions. The protrusions abut against the bottom side of the photovoltaic panel. The second through hole is formed in the recess. A steel washer is provided at the position of the recess and the second through hole to reinforce the structural strength when the buckle plate is connected. The height of the steel washer is less than the distance between the recess and the protrusion along the bolt axis.

[0012] Optionally, both ends of the pressure plate are arc-shaped structures at the locations where the through holes are formed, and the arc-shaped structures are adapted to the mounting frame.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. This application improves the structure of the clips used to fix the photovoltaic panel when it is installed on the mounting frame, thereby avoiding clamping of the photovoltaic panel and preventing friction between the photovoltaic panel and the clips and the mounting frame when the photovoltaic panel shakes, which would damage the structure of the photovoltaic panel.

[0015] 2. The clips in this application can be used to connect multiple photovoltaic panels, enabling them to be used in more scenarios and offering more comprehensive functions;

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] This application discloses a photovoltaic panel stabilizing fastener.

[0023] Reference Figure 1 A photovoltaic panel stabilizing fastener is disclosed for fixing a photovoltaic panel 1 to a mounting frame. A mounting frame 11 is provided on the bottom side of the photovoltaic panel 1, with a gap between the mounting frame 11 and the bottom side of the photovoltaic panel 1. The fastener includes a pressure plate 2 and a snap-on plate 3 detachably mounted on the pressure plate 2. When the photovoltaic panel 1 needs to be installed, the pressure plate 2 rests on the mounting frame of the photovoltaic panel 1 and its top abuts against the mounting frame 11, while the snap-on plate 3 is placed at the gap between the mounting frame 11 and the bottom side of the photovoltaic panel 1. A through hole 21 communicating with the bottom side of the mounting frame is provided on the pressure plate 2, and a through hole 321 coinciding with the through hole 21 is provided on the snap-on plate 3. A bolt 4 passes through both the through hole 21 and the through hole 321, and a nut for clamping the mounting frame 11 is fitted on the bolt 4. When the nut is tightened, the bolt 4 forces the pressure plate 2 and the snap-on plate 3 closer together, achieving a stable clamping effect.

[0024] Meanwhile, several baffles 22 are vertically arranged on the pressure plate 2, and the baffles 22 together abut against the side of the photovoltaic panel 1 to achieve lateral restriction of the photovoltaic panel 1.

[0025] This structure prevents the fasteners from contacting the effective working surface of the photovoltaic panel 1, thus protecting the structure of the photovoltaic panel 1.

[0026] Reference Figure 1 and Figure 2 Furthermore, two through holes 21 are symmetrically opened at both ends along the length of the pressure plate 2, and the baffles 22 on the same pressure plate 2 are all located on a uniform vertical surface in the middle of the pressure plate 2. When it is necessary to install another photovoltaic panel 1 on the adjacent side of the photovoltaic panel 1, this structure can stably connect the two photovoltaic panels 1 into a whole, expanding the application scope of the fastener of this application and making it more practical.

[0027] Reference Figure 1 and Figure 2Furthermore, there are two baffles 22 on the pressure plate 2, and both baffles 22 are formed by bending a portion of the pressure plate 2 after shearing. The two baffles 22 are symmetrically arranged in the width direction of the pressure plate 2. When two adjacent photovoltaic panels 1 are attached together, the inner sides of the two pressure plates 2 abut against the sides of the two adjacent photovoltaic panels 1 respectively, so as to achieve stable positioning of the photovoltaic panels 1.

[0028] Reference Figure 2 and Figure 3 The through hole 21 is an oblong hole. When the bolt 4 is not tightened, it can slide along the length of the oblong hole, so as to quickly adjust the buckle plate 3 to the most suitable installation position, making the installation of the buckle of this application more convenient and flexible.

[0029] Preferably, a baffle 33 is vertically provided on the side of the buckle plate 3 away from the pressure plate 2, and the inner side of the baffle 33 abuts against the inner side of the mounting frame 11. When the bolt 4 is tightened, the baffle 33 and the baffle plate 22 work together to completely limit the mounting frame 11 and the photovoltaic panel 1 connected to the mounting frame 11, ensuring that the photovoltaic panel 1 is stable when it shakes. At the same time, the baffle 33 designed in this application can also help the buckle plate 3 find a suitable installation position, improving the convenience of photovoltaic panel 1 installation.

[0030] Reference Figure 1 and Figure 3 The buckle plate 3 specifically includes protrusions 31 at both ends and a recess 32 located between the two protrusions 31. The second through hole 321 is opened at the position of the recess 32. A steel washer 322 is also installed on the buckle plate 3 at the position of the second through hole 321. The steel washer 322 can increase the strength of the connection structure when the pressure plate 2 and the buckle plate 3 are connected by bolts 4, ensuring that the connection structure is more stable.

[0031] In order to ensure that the connection of bolt 4 is not affected, the height of steel washer 322 is designed to be less than the height difference between recess 32 and protrusion 31, so as to prevent damage to the structure of baffle 33 itself when bolt 4 is rotated.

[0032] Reference Figure 1 and Figure 2 Preferably, both ends of the pressure plate 2 are arc-shaped structures 23 at the locations where through holes 21 are opened, and the arc-shaped structures 23 are adapted to the mounting frame 11. This structure is to ensure that the pressure plate 2 can be stably placed on the mounting frame, reducing the possibility of the photovoltaic panel 1 shaking.

[0033] The implementation principle of a photovoltaic panel stabilizing fastener according to an embodiment of this application is as follows:

[0034] First, place the pressure plate 2 on the mounting frame, then place the buckle plate 3 between the bottom side of the photovoltaic panel 1 and the mounting frame 11. Finally, use bolts 4 to pass through the mounting frame, pressure plate 2, mounting frame 11 and buckle plate 3 in sequence and add nuts to achieve vertical clamping and bonding of multiple parts.

[0035] During this process, the baffle 22 on the pressure plate 2 abuts against the side of the photovoltaic panel 1, while the baffle 33 on the buckle plate 3 abuts against the inner side of the mounting frame 11. The two work together to achieve lateral positioning of the photovoltaic panel 1, ensuring that the photovoltaic panel 1 and the mounting frame can be connected quickly and stably.

[0036] Meanwhile, in this application, the pressure plate 2 has two through holes 21 along its length, so that the connection between two adjacent photovoltaic panels 1 can be achieved by connecting a buckle plate 3 to each end of the pressure plate 2, which is more practical.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
