Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel pressing blocks, in particular to an outward-turning quick-installing middle pressing block. Background Art

[0002] Photovoltaic panel installation and erection structures can be used to effectively fix photovoltaic panels outdoors, allowing them to effectively receive sunlight and convert solar energy into electrical energy. The pressure block is an important component of the photovoltaic panel installation structure, which connects and fixes adjacent photovoltaic panels and installation structures.

[0003] For example, the Chinese utility model patent with authorization announcement number CN210380722U: a rooftop photovoltaic panel bracket discloses a fastening support, which includes a support seat and a pressure block; a photovoltaic panel is pressed onto the support seat using a second nut, and at the same time, the fastening support is pressed onto the horizontal adjustment block, which is a photovoltaic panel installation technical solution.

[0004] Although the above utility model patent can use the pressure block to install and fix the photovoltaic panel, it needs to be fixed with the help of bolts, the structure is complex and the installation process is cumbersome. Therefore, the field urgently needs an outward-turned quick-install medium pressure block to solve the problems existing in the prior art. Utility Model Content

[0005] The utility model aims to provide an outward-turning quick-install middle pressure block to solve the above-mentioned shortcomings in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The outward-flip quick-install middle pressure block comprises a top plate, wherein the first and second abutment plates extending downward are respectively fixed at opposite ends of the top plate, and abutment side plates are respectively fixed at opposite ends of the top plate away from the positions of the first and second abutment plates, and the two abutment side plates can be connected and fixed to two adjacent photovoltaic panels; a limiting plate is fixed on a side wall of the first abutment plate away from the second abutment plate, and a limiting plate is fixed on a side wall of the second abutment plate away from the first abutment plate, and a free end of the limiting plate extends obliquely upward;

[0008] The pressing side plate comprises a first extension plate and a second extension plate connected end to end, the first extension plate is connected and fixed to the top plate, the first extension plate is inclined downward relative to the top plate surface, and the second extension plate is inclined upward relative to the first extension plate surface;

[0009] By adopting the above technical scheme, multiple photovoltaic panels are mounted on C-shaped steel, and pressure blocks are installed from the gaps between adjacent photovoltaic panels. The pressure blocks are applied with force toward the inside of the C-shaped steel. The limiting plate is squeezed by the C-shaped steel, and the limiting plate, the first abutment plate, and the second abutment plate produce elastic deformation toward the middle of the pressure block; the bottom of the abutment side plate abuts against the top surface of the photovoltaic panel frame, and force is continued to be applied to the pressure block, and the abutment side plate produces elastic deformation; force is continued to be applied to the pressure block until the limiting plate is embedded in the C-shaped steel groove. At this time, the limiting plate and the abutment side plate complete the clamping and fixing of the C-shaped steel and the two adjacent photovoltaic panels, and have a tendency to recover deformation, so that the fixing effect of the photovoltaic panel is good, and it has the elastic adaptability function to cope with external impact force, thereby extending the service life of the C-shaped steel, photovoltaic panel, and pressure block, and reducing maintenance costs.

[0010] As a preferred solution, the first and second abutment plates are both provided with movable grooves near the limiting plate, and the area of ​​the movable grooves is larger than the surface area of ​​the limiting plate near the movable groove. When the limiting plate is deformed during the installation process, the limiting plate can enter the movable groove, which can reduce the degree of deformation of the first and second abutment plates during the installation process, reduce the difficulty of installation, and increase the installation efficiency.

[0011] As a preferred solution, the first abutment plate comprises a first L-shaped plate connected and fixed to the top plate, and a third L-shaped plate is connected and fixed to one end of the first L-shaped plate away from the top plate; the second abutment plate comprises a second L-shaped plate connected and fixed to the top plate, and a fourth L-shaped plate is connected and fixed to one end of the second L-shaped plate away from the top plate; the free ends of the third L-shaped plate and the fourth L-shaped plate are close to each other; the movable groove and the limit plate are located on the third L-shaped plate and the fourth L-shaped plate;

[0012] By adopting the above technical scheme, the first abutment plate and the second abutment plate spliced ​​in L shape are stepped and have better deformation adaptability, which can further prevent the photovoltaic panel from being damaged by external force. After the installation of the pressing block is completed, the bottom of the first L-shaped plate and the second L-shaped plate can be close to the upper surface of the C-shaped steel, so that the installation of the pressing block is more stable; when the pressing block is squeezed by the photovoltaic panel, the free ends of the third L-shaped plate and the fourth L-shaped plate abut against each other, so that the pressing block as a whole is not easy to deform significantly, the fixing effect of the photovoltaic panel is good, and it is beneficial to reduce the maintenance cost of the pressing block.

[0013] As a preferred solution, the angle between the first extension plate surface and the top plate surface is 10°-15°, and the angle between the second extension plate surface and the first extension plate surface is 180°-185°. By adopting the above-mentioned angle range, while ensuring that the pressing side plate can cooperate with the limiting plate to effectively fix the photovoltaic panel, it can effectively avoid excessive deformation of the pressing side plate during the installation process to cause rigid deformation or breakage.

[0014] As a preferred solution, the angle between the first extension plate surface and the top plate surface is 13°, and the angle between the second extension plate surface and the first extension plate surface is 183°.

[0015] As a preferred solution, the second extension plate is provided with reinforcing ribs to enhance the strength of the pressing side plate.

[0016] As a preferred solution, the third L-shaped plate has a rounded corner at the bottom near one end of the fourth L-shaped plate, and a slot is provided at the bottom of the rounded corner; the fourth L-shaped plate has a protrusion fixed at the top near one end of the third L-shaped plate, and the protrusion matches the shape of the slot.

[0017] By adopting the above technical solution, before assembling the C-shaped steel, photovoltaic panel and pressing block, the first abutment plate and the second abutment plate are bent to produce a relative upward and downward displacement deformation, and then a force is applied to the first abutment plate and the second abutment plate to approach each other, so that the protrusion slides along the rounded surface until it is stuck in the slot; then the C-shaped steel, photovoltaic panel and pressing block are assembled. In this process, the protrusion will move in the direction of continuing to approach the third L-shaped plate and leave the slot; when the limit plate is embedded in the C-shaped steel groove, the limit plate, the first abutment plate and the second abutment plate are The plates recover their deformation at the same time, and the protrusions, with the help of the inertia of the instantaneous deformation recovery force of the limit plate, the first abutment plate, and the second abutment plate, and the jitter caused by the deformation recovery, quickly recover to the state where the third L-shaped plate and the fourth L-shaped plate end are abutted, and the pressure block is installed. At this time, the third L-shaped plate and the fourth L-shaped plate respectively have deformation recovery forces in the direction of each other, which makes the friction between the C-shaped steel and the third L-shaped plate and the fourth L-shaped plate greater. While saving raw materials, the installation stability between the C-shaped steel and the pressure block is further enhanced.

[0018] As a preferred solution, the pressing block is an integrally formed structure.

[0019] Beneficial effects:

[0020] 1. This solution uses C-shaped steel as the frame supporting the photovoltaic panel, and designs a pressing block that can closely match the C-shaped steel. The assembly between the C-shaped steel, photovoltaic panel and pressing block can be completed conveniently and quickly by pressing in, without the need for bolts, with low cost and high installation efficiency;

[0021] 2. This solution can deal with external impacts, such as strong winds and human damage, by using the elastic deformation of the compression block itself to reduce the damage to the photovoltaic panel;

[0022] 3. The pressure side plate in this solution has a multi-angle deformation design, which can effectively prevent the pressure side plate from excessively deforming and causing rigid deformation or breakage during installation while ensuring that the pressure side plate can cooperate with the limit plate to effectively fix the photovoltaic panel;

[0023] 4. The design of this solution can increase the friction between the C-shaped steel and the third L-shaped plate and the fourth L-shaped plate, and further enhances the installation stability between the C-shaped steel and the pressing block while saving raw materials.

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] like Figure 1-Figure 4 , Fig. 9 , Fig.10 As shown, the outward-turning quick-install middle pressure block includes a top plate 201, and the top plate 201 has a first abutment plate 200 and a second abutment plate 2001 extending downwardly formed on opposite ends thereof, and abutment side plates 204 are formed on opposite ends of the top plate 201 away from the positions of the first abutment plate 200 and the second abutment plate 2001, respectively. The two abutment side plates 204 can connect and fix two adjacent photovoltaic panels 102; a limiting piece 302 is formed on the side wall of the first abutment plate 200 away from the second abutment plate 2001, and a limiting piece 302 is formed on the side wall of the second abutment plate 2001 away from the first abutment plate 200, and the free end of the limiting piece 302 extends obliquely upward;

[0038] The pressing side plate 204 includes a first extension plate and a second extension plate formed in one piece. The first extension plate is formed in one piece with the top plate 201. The first extension plate is inclined downward relative to the top plate 201, and the second extension plate is inclined upward relative to the first extension plate.

[0039] By adopting the above technical solution, multiple photovoltaic panels 102 are mounted on the C-shaped steel 101, and the pressing block 103 is installed from the gap between the adjacent photovoltaic panels 102. The pressing block 103 is applied to the inner direction of the C-shaped steel 101, and the limiting piece 302 is squeezed by the C-shaped steel 101. The limiting piece 302, the first abutting plate 200, and the second abutting plate 2001 produce elastic deformation toward the middle direction of the pressing block 103; the bottom of the pressing side plate 204 is in contact with the top surface of the frame of the photovoltaic panel 102, and the pressing block 103 continues to be applied with force. The side plate 204 produces elastic deformation; continue to apply force to the pressing block 103 until the limiting piece 302 is embedded in the groove of the C-shaped steel 101. The limiting piece 302 and the pressing side plate 204 now complete the clamping and fixing of the C-shaped steel 101 and the two adjacent photovoltaic panels 102, and have a tendency to restore deformation, so that the fixing effect of the photovoltaic panel 102 is good, and it has the elastic adaptability function to cope with external impact force, thereby extending the service life of the C-shaped steel 101, the photovoltaic panel 102, and the pressing block 103, and reducing maintenance costs.

[0040] The first abutment plate 200 and the second abutment plate 2001 are both provided with movable grooves 301 near the limiting plate 302. The area of ​​the movable grooves 301 is larger than the surface area of ​​the limiting plate 302 near the movable grooves 301. When the limiting plate 302 is deformed during installation, the limiting plate 302 can enter the movable grooves 301, which can reduce the degree of deformation of the first abutment plate 200 and the second abutment plate 2001 during installation, reduce the difficulty of installation, and increase installation efficiency.

[0041] The first abutment plate 200 includes a first L-shaped plate 202 integrally formed with the top plate 201, and a third L-shaped plate 203 is integrally formed at one end of the first L-shaped plate 202 away from the top plate 201; the second abutment plate 2001 includes a second L-shaped plate 2021 integrally formed with the top plate 201, and a fourth L-shaped plate 2031 is integrally formed at one end of the second L-shaped plate 2021 away from the top plate 201; the free ends of the third L-shaped plate 203 and the fourth L-shaped plate 2031 are close to each other; the movable groove 301 and the limiting piece 302 are located on the third L-shaped plate 203 and the fourth L-shaped plate 2031;

[0042] By adopting the above technical scheme, the first abutment plate 200 and the second abutment plate 2001 which are spliced ​​in an L shape are stepped and have better deformation adaptability, which can further prevent the photovoltaic panel 102 from being squeezed and damaged by external force. After the installation of the pressing block 103 is completed, the bottom of the first L-shaped plate 202 and the second L-shaped plate 2021 can be close to the upper surface of the C-shaped steel 101, so that the installation of the pressing block 103 is more stable; when the pressing block 103 is squeezed by the photovoltaic panel 102, the free ends of the third L-shaped plate 203 and the fourth L-shaped plate 2031 abut against each other, so that the pressing block 103 as a whole is not easy to deform significantly, the fixing effect of the photovoltaic panel 102 is good, and it is beneficial to reduce the maintenance cost of the pressing block 103.

[0043] The included angle between the first extension plate surface and the top plate 201 surface is 13°, and the included angle between the second extension plate surface and the first extension plate surface is 183°.

[0044] A reinforcing rib 205 is punched on the second extension plate to increase the strength of the side plate 204 .

[0045] Embodiment 2, as Figure 5-Figure 8 As shown, based on the scheme of Example 1, a rounded corner 401 is provided at the bottom of the third L-shaped plate 203 close to the fourth L-shaped plate 2031, and a slot 402 is provided at the bottom of the rounded corner 401; a protrusion 403 is fixed at the top of the fourth L-shaped plate 2031 close to the third L-shaped plate 203, and the protrusion 403 matches the shape of the slot 402.

[0046] By adopting the above technical solution, before assembling the C-shaped steel 101, the photovoltaic panel 102 and the pressing block 103, the first abutment plate 200 and the second abutment plate 2001 are bent to produce a deformation of relative upward and downward displacement, and then a force is applied to the first abutment plate 200 and the second abutment plate 2001 to approach each other, so that the protrusion 403 slides along the surface of the rounded corner 401 until it is inserted into the slot 402; then the C-shaped steel 101, the photovoltaic panel 102 and the pressing block 103 are assembled. In this process, the protrusion 403 will move in the direction of continuing to approach the third L-shaped plate 203 and disengage from the slot 402; when the limiting piece 302 is embedded in the groove of the C-shaped steel 101, the limiting piece 302 and the first abutment plate 2 00 and the second abutment plate 2001 restore their deformations at the same time, and the protrusion 403, with the help of the inertia of the instantaneous deformation recovery force of the limiting plate 302, the first abutment plate 200 and the second abutment plate 2001 and the shaking caused by the deformation recovery, quickly restores to the state where the third L-shaped plate 203 and the fourth L-shaped plate 2031 end are in abutment with each other, and the installation of the pressing block 103 is completed. At this time, the third L-shaped plate 203 and the fourth L-shaped plate 2031 respectively have deformation recovery forces in the direction of each other, so that the friction between the C-shaped steel 101 and the third L-shaped plate 203 and the fourth L-shaped plate 2031 is greater, and the installation stability between the C-shaped steel 101 and the pressing block 103 is further enhanced while saving raw materials.

[0047] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
