Description

An edge clamping mechanism for fixing photovoltaic modules Technical Field

[0001] This application relates to the field of photovoltaic equipment installation technology, and in particular to a side clamping block mechanism for fixing photovoltaic modules. Background Technology

[0002] In existing photovoltaic power plant technical solutions, the installation of photovoltaic modules typically uses bolts and aluminum alloy clamps for fixing. Since photovoltaic modules generally adopt a frame and photovoltaic panel structure, the aluminum alloy clamps used for the frame are usually stepped in shape. The upper step presses against the frame, the lower step presses against the metal bracket, and bolts are installed on the middle step for locking. However, due to its structural problems, this type of clamp lacks reliability, especially in areas with high wind pressure and frequent typhoons, where many clamps are damaged, seriously affecting system safety. Summary of the Invention

[0003] To address the aforementioned issues, this technical solution provides an edge-pressing block mechanism for fixing photovoltaic modules.

[0006] Side pressing blocks are located on the side of photovoltaic modules and are used to press the photovoltaic modules.

[0007] The edge pressing block includes a main board portion, an inner limiting portion protruding below the main board portion, and a right support portion located on the right side of the main board portion. The main board portion includes a body portion located between the inner limiting portion and the right support portion, and a left support portion located to the left of the inner limiting portion. The left support portion is used to press against the photovoltaic module, and the inner limiting portion is used to press against the side of the photovoltaic module to limit its movement. The right support portion extends downward from the main board portion to support a metal bracket.

[0008] The main body is provided with two third connecting holes for fasteners to pass through;

A plurality of anti-slip teeth extend along the front-back direction of the main board and are spaced apart along the left-right direction.

[0012] An edge pressing block mechanism for fixing a photovoltaic module as described above, wherein the edge of the left support portion is provided with an outward limiting portion protruding downward, and the protruding length of the outward limiting portion is shorter than that of the inward limiting portion.

[0013] An edge pressing block mechanism for fixing a photovoltaic module as described above, wherein the right support portion is L-shaped, its upper end is connected to the right side of the main body portion, and its lower end is used to press against the metal bracket.

[0014] An edge pressing block mechanism for fixing a photovoltaic module as described above further includes a fixing component, which includes a pressing block connecting piece for abutting against the bottom surface of the metal bracket, a fastening member, and a locking member. The fastening member passes through the edge pressing block and the pressing block connecting piece and then is connected to the locking member to lock the photovoltaic module on the top surface of the metal bracket.

The pressing block connecting piece is provided with two second connecting holes arranged at intervals, and the fastening member passes through the second connecting holes.

[0018] An edge pressing block mechanism for fixing a photovoltaic module as described above, wherein the fastening member includes a transverse portion, and linear portions provided at both ends of the transverse portion and perpendicular to each other. The transverse portion is recessed in an arc shape toward the opening direction between the two linear portions.

[0019] The beneficial effects of this application are:

[0020] The present utility model provides an edge pressing block mechanism for fixing a photovoltaic module, which innovates in mechanical design. The left support portion and the right support portion protrude below the main board portion and are arranged at intervals, so that a half "π" - shaped structure is formed on the left side of the main board portion, and a half "J" - shaped structure is formed on the right side. The third connecting hole is located on the main body portion.

[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] An edge clamping block mechanism for fixing photovoltaic modules, characterized in that: it includes...

[0027] Side pressing block 3 is located on the side of the photovoltaic module and is used to press the photovoltaic module.

[0028] The edge pressing block 3 includes a main board portion 31, an inner limiting portion 32 protruding below the main board portion 31, and a right support portion 33 located on the right side of the main board portion 31. The main board portion 31 includes a main body portion 311 located between the inner limiting portion 32 and the right support portion 33, and a left support portion 312 located to the left of the inner limiting portion 32. The left support portion 312 is used to press against the photovoltaic module, and the inner limiting portion 32 is used to press against the side of the photovoltaic module to limit its movement. The right support portion 33 extends downward from the main board portion 31 to support a metal bracket.

[0029] The main body 311 is provided with two third connecting holes 314 for fasteners to pass through;

[0030] The main board portion 31, the inner limiting portion 32, and the right support portion 33 are integrally formed.

[0031] The utility model provides an edge pressing block mechanism for fixing photovoltaic modules, which innovates in mechanical design. The left support part and the right support part protrude below the main board part and are arranged at intervals, so that a half "π" - shaped structure is formed on the left side of the main board part, and a half "J" - shaped structure is formed on the right side. The third connection hole is located on the main body part. The fastener passes through the first connection hole, and when stressed, it is conducted from the main body part to the left support part and the right support part, and finally acts on the photovoltaic module and the metal bracket. Since the forces received by the left support part and the right support part are both downward, there is no bending position during the force conduction process, which greatly optimizes the force - receiving situation where the left side of the stepped structure is under pressure and the right side is under tension, and optimizes the bending and deformation problems that occur during construction and high - wind pressure.

[0032] Further, as a preferred implementation manner of this solution rather than a limitation, the thickness of the main board part 31 is greater than or equal to 4 mm.

[0033] Further, as a preferred implementation manner of this solution rather than a limitation, anti - slip teeth 34 protrude from the bottom surfaces of the left support part 312 and the right support part 33. The plurality of anti - slip teeth 34 extend along the front - rear direction of the main board part 31 and are arranged at intervals along the left - right direction. The anti - slip teeth are used to increase the friction force.

[0034] Further, as a preferred implementation manner of this solution rather than a limitation, an outer limiting part 313 protruding downward is provided at the edge of the left support part 312. The protruding length of the outer limiting part 313 is less than the protruding length of the inner limiting part 32. The outer limiting part is used to directly abut against the photovoltaic module. The protrusion of the outer limiting part can adapt to the arc - shaped frame of the photovoltaic module.

[0035] Further, as a preferred implementation manner of this solution rather than a limitation, the right support part 33 is L - shaped, its upper end is connected to the right side of the main body part 311, and its lower end is used to press against the metal bracket.

[0036] Further, as a preferred implementation manner of this solution rather than a limitation, the two third connection holes 314 are arranged at intervals along the front - rear direction of the main body part 311.

[0037] Further, as a preferred implementation manner of this solution rather than a limitation, it further includes a fixing component 2, which includes a pressing - block connecting part 21 for abutting against the bottom surface of the metal bracket, a fastener 22, and a locking part 23. The fastener 22 passes through the edge pressing block 3 and the pressing - block connecting part 21 and then is connected to the locking part 23 to lock the photovoltaic module on the top surface of the metal bracket.

[0038] Further, as a preferred implementation manner of this solution rather than a limitation, the fastener 22 connects the pressing - block connecting part 21 and the edge pressing block 3 on the front and rear sides of the metal bracket. This is beneficial to increasing the connection strength.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the fastener 22 is a U-bolt, the locking element 23 is a nut, and the two ends of the fastener 22 pass through the two third connecting holes 314 and are threadedly connected to the locking element 23.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the pressure block connector 21 is U-shaped with its opening facing downwards towards the metal bracket. The pressure block connector 21 has two spaced-apart second connecting holes 211 through which the fastener 22 passes. Using U-bolt clamps for fixing, compared to existing single-bolt fixing, makes the photovoltaic module more secure and reliable.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the fastener 22 includes a transverse portion 221 and straight portions 222 disposed at both ends of the transverse portion 221 and perpendicular to each other. The transverse portion 221 is arc-shaped and recessed towards the opening between the two straight portions 222. When locking, the transverse portion applies pressure to the edge pressure block, while the elasticity of the transverse portion itself prevents over-tightening and damage to the photovoltaic module.

[0042] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
