Description

Technical Field

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

[0002] The photovoltaic panel bracket is a supporting and fixing structure for outdoor installation of photovoltaic panels. The photovoltaic panel bracket in the prior art uses channel steel as a supporting member to support the photovoltaic panel off the ground. The pressure block is an important component in the photovoltaic panel bracket, and the pressure block can be used to connect and fix the channel steel and the photovoltaic panel.

[0003] For example, the Chinese invention patent with authorization announcement number CN102900206B: A bracket system for installing a solar photovoltaic panel assembly, including a locking nut that is located in a channel steel during installation and whose upper surface is tightly attached to the end of the rolled flange of the channel steel, and a first fastener that fastens the pressure block to the locking nut.

[0004] The above invention patent utilizes a pressure block and a locking nut to achieve fixed installation of the photovoltaic panel, but the structure is complex and the installation operation is cumbersome. Therefore, the field urgently needs an inward-turning quick-install pressure block to solve the problems existing in the prior art. Utility Model Content

[0005] The utility model aims to provide an inward-turning quick-installing medium-pressure block to solve the technical problem of complicated operation steps for installing photovoltaic panels in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inward-turning quick-install middle pressure block, including a groove-shaped steel, a mounting groove is opened on the side wall of the groove-shaped steel, a plurality of photovoltaic panels are supported on the groove-shaped steel, and a pressure block is installed between the photovoltaic panel and the groove-shaped steel. The pressure block includes a top plate, and the opposite ends of the top plate are respectively fixed with side plates pointing vertically downward, and the opposite ends of the top plate avoiding the position of the side plates are respectively fixed with top pressure plates, the lower surface of the top pressure plate contacts the upper surface of the photovoltaic panel frame, and the top pressure plate provides downward pressure to fix the photovoltaic panel. The top pressure plates located at the two ends of the top plate respectively fix one photovoltaic panel, and the side wall of the side plate close to the top plate is fixed with a bottom top plate, and the free end of the bottom top plate faces obliquely upward; the bottom top plate can be stuck in the mounting groove, The top of the bottom top plate is in contact with the top wall of the installation groove, the bottom top plate provides an upward thrust to the groove steel and the photovoltaic panel, and the top pressure plate provides a downward thrust to the groove steel and the photovoltaic panel, so that the photovoltaic panel and the groove steel are tightly fixed together. During assembly, the pressing block is pressed downward from the gap between adjacent photovoltaic panels, and after the top pressure plate contacts the photovoltaic panel, it continues to press down, and the top pressure plate produces elastic deformation; in this process, the bottom top plate contacts the side wall of the groove steel, and the bottom top plate is hindered by the side wall of the groove steel and produces elastic deformation, and continues to press down until the bottom top plate is stuck in the installation groove, the bottom top plate rebounds completely, and the top pressure plate produces incomplete rebound, completing the fixing function between the groove steel and the photovoltaic panel, and the assembly process is simple, without the need to use bolts or other parts with complicated assembly process.

[0007] The gap between the top of the bottom roof plate and the side plates is smaller than the wall thickness of the channel steel.

[0008] As a preferred solution, the side plate is provided with a movable groove near the bottom top plate area, and the area of ​​the movable groove is larger than the maximum side wall area of ​​the bottom top plate, so that during the installation process, the pressing block can be immersed in the movable groove when the bottom top plate is deformed, reducing the difficulty of installation.

[0009] As a preferred solution, reinforcing ribs are stamped on both sides of the side panel surface to improve the strength of the side panel.

[0010] As a preferred solution, a slot is opened through the center of the side panel surface to strengthen the ribs and increase the strength of the side panel. The slot saves raw material costs, so that the side panel meets the installation strength requirements while saving costs.

[0011] As a preferred solution, reinforcing ribs are stamped at the junction of the top plate and the side plates.

[0012] As a preferred solution, reinforcing ribs are stamped on the surface of the top pressure plate.

[0013] As a preferred solution, a dividing groove is horizontally opened on the edge of the bottom top plate along the opening direction of the movable groove, and the dividing groove divides a number of auxiliary top plates. During the on-site assembly of the pressing block, photovoltaic panel, and groove-shaped steel, due to thermal expansion and contraction, dimensional errors of components and the like, the positional relationship between the bottom top plate and the mounting groove may be misaligned, which makes it impossible or impossible for the bottom top plate to be quickly inserted into the mounting groove in the horizontal direction. With the above technical solution, under normal circumstances, the bottom top plate and the auxiliary top plate are simultaneously inserted into the movable groove. When there is an installation error, the bottom top plate is inserted into the movable groove, part of the auxiliary top plate is against the outer wall of the groove-shaped steel, and the deformation recovery force of the auxiliary top plate is small, which will not affect the normal fixing function of the pressing block.

[0014] As a preferred solution, the bottom thickness of the secondary top sheet is smaller than the bottom thickness of the bottom top plate, so as to further reduce the deformation recovery force of the secondary top sheet.

[0015] As a preferred solution, the width of the dividing groove is greater than 2 mm. After the pressure block, photovoltaic panel and groove steel are assembled, during use, due to wind factors, slight dynamic friction will be generated between the pressure block and the groove steel, providing sufficient space for the secondary top sheet to move, so that the secondary top sheet pressed against the outer wall of the groove steel can be easily bent in the horizontal direction, further reducing the force of the secondary top sheet on the groove steel.

[0016] As a preferred solution, the top pressure plate includes 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.

[0017] Beneficial effects:

[0018] 1. This solution uses a quick clamping installation method to complete the rapid assembly of photovoltaic panels and channel steel without the help of bolts or other parts, with high assembly efficiency and cost savings;

[0019] 2. This solution is designed with a top pressure plate of a special shape, which can prevent the top pressure plate from being torn easily, and improve the connection and fixing effect of the photovoltaic panel and the channel steel;

[0020] 3. This solution is designed with a secondary top plate to assist in the connection between the bottom top plate and the channel steel. It can address installation difficulties caused by thermal expansion and contraction and component size errors, improve the fault tolerance rate, and facilitate installation.

DETAILED DESCRIPTION

[0032] 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.

[0033] Embodiment 1, as Figure 1-6As shown, the inner flip quick-install middle pressure block includes a channel steel 300, a mounting groove 301 is opened on the side wall of the channel steel 300, a plurality of photovoltaic panels 200 are supported on the channel steel 300, and a pressure block 100 is connected and installed between the photovoltaic panels 200 and the channel steel 300, characterized in that: the pressure block 100 includes a top plate 101, and the top plate 101 has two opposite ends respectively integrally formed with side plates 102 extending vertically downward, and the top plate 101 has two opposite ends respectively integrally formed with top pressure plates away from the position where the side plates 102 are located. The top plate 103 has a lower surface in contact with the upper surface of the frame of the photovoltaic panel 200, and the top plate 103 provides downward pressure to fix the photovoltaic panel 200. The top plates 103 at both ends of the top plate 101 respectively fix one photovoltaic panel 200. The side plate 102 is integrally formed with a bottom plate 104 on the side wall close to the top plate 101, and the free end of the bottom plate 104 faces obliquely upward; the bottom plate 104 can be inserted into the installation groove 301, and the bottom plate 104 can be inserted into the installation groove 301. The top of 04 is in contact with the top wall of the installation groove 301, the bottom top plate 104 provides an upward thrust to the groove steel 300 and the photovoltaic panel 200, and the top pressure plate 103 provides a downward thrust to the groove steel 300 and the photovoltaic panel 200, so that the photovoltaic panel 200 and the groove steel 300 are tightly fixed together. When assembling, the pressing block 100 is pressed downward from the gap between adjacent photovoltaic panels 200. After the top pressure plate 103 contacts the photovoltaic panel 200, it continues to press downward, and the top pressure plate 103 produces Elastic deformation; in this process, the bottom top plate 104 contacts the side wall of the groove steel 300, and the bottom top plate 104 is hindered by the side wall of the groove steel 300 and produces elastic deformation, and continues to be pressed down until the bottom top plate 104 is stuck in the installation groove 301. The bottom top plate 104 rebounds completely, and the top pressure plate 103 produces an incomplete rebound, completing the fixing function between the groove steel 300 and the photovoltaic panel 200. The assembly process is simple and does not require the use of bolts or other parts that complicate the assembly process.

[0034] The gap between the top of the bottom top plate 104 and the side plate 102 is smaller than the wall thickness of the channel steel 300 .

[0035] The side plate 102 is provided with a movable groove 105 near the bottom top plate 104. The area of ​​the movable groove 105 is larger than the maximum side wall area of ​​the bottom top plate 104. During the installation process, the bottom top plate 104 of the pressing block 100 can be immersed in the movable groove 105 when it is deformed, thereby reducing the difficulty of installation.

[0036] Reinforcing ribs 106 are stamped on both sides of the side plate 102 to improve the strength of the side plate 102 .

[0037] A reinforcing rib 106 is punched at the junction between the top plate 101 and the side plate 102 .

[0038] A reinforcing rib 106 is stamped on the surface of the top pressing plate 103 .

[0039] Embodiment 2, as Figure 7-8 As shown, on the basis of the scheme of Example 1, a dividing groove 402 is horizontally opened on the edge of the bottom top plate 104 along the opening direction of the movable groove 105, and the dividing groove 402 divides a plurality of auxiliary top sheets 401. During the on-site assembly process of the pressing block 100, the photovoltaic panel 200, and the channel steel 300, due to thermal expansion and contraction, size errors of parts and components, the positional relationship between the bottom top plate 104 and the installation groove 301 will be misaligned, which makes it impossible or impossible for the bottom top plate 104 to be quickly inserted into the installation groove 301 in the horizontal direction. With the above technical solution, under normal circumstances, the bottom top plate 104 and the auxiliary top sheet 401 are simultaneously inserted into the movable groove 105. When there is an installation error, the bottom top plate 104 is inserted into the movable groove 105, part of the auxiliary top sheet 401 is against the outer wall of the channel steel 300, and the deformation recovery force of the auxiliary top sheet 401 is small, which will not affect the normal fixing function of the pressing block 100.

[0040] The bottom thickness of the secondary top sheet 401 is less than the bottom thickness of the bottom top plate 104 , which further reduces the deformation recovery force of the secondary top sheet 401 .

[0041] A slot 501 is provided through the center of the side plate 102 to enhance the strength of the side plate 102 with the reinforcement rib 106. The slot 501 saves the cost of raw materials, so that the side plate 102 meets the installation strength requirements while saving costs.

[0042] The width of the dividing groove 402 is 3 mm. After the pressure block 100, the photovoltaic panel 200 and the channel steel 300 are assembled, during use, due to wind factors, a slight dynamic friction will be generated between the pressure block 100 and the channel steel 300, providing sufficient movement space for the auxiliary top sheet 401, so that the auxiliary top sheet 401, which is pressed against the outer wall of the channel steel 300, is easy to bend in the horizontal direction, further reducing the force of the auxiliary top sheet 401 on the channel steel 300.

[0043] Embodiment 3, as Fig. 9 As shown, on the basis of the scheme of Example 2, the top pressure plate 103 includes a first extension plate and a second extension plate which are connected end to end and formed as one piece, the first extension plate and the top plate 101 are formed as one piece, the first extension plate is inclined downward relative to the plate surface of the top plate 101, and the second extension plate is inclined upward relative to the plate surface of the first extension plate; the angle between the plate surface of the first extension plate and the plate surface of the top plate 101 is 13°, and the angle between the plate surface of the second extension plate and the plate surface of the first extension plate is 183°, which can make the top pressure plate 103 less likely to tear and improve the connection and fixing effect of the photovoltaic panel 200 and the channel steel 300.

[0044] 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.
