[0002] Photovoltaic module is applied to the power generation device of converting solar light into electric energy, and is usually arranged in open and unobstructed area, and the photovoltaic module needs to be fixed with the support, and the flexible support is usually used to install the photovoltaic module in the present use, and the single photovoltaic module is fixed on the flexible support by the connecting device one by one during installation, and then the flexible support is installed in the specified area, the structure of the existing connecting device is usually connected with the flexible support at one end, and the hole matched with screw and the hole carried by the frame of the photovoltaic module are fixed at the other end, but the photovoltaic module is usually disturbed by wind due to the open area, so the shaking of the photovoltaic module is very serious when the photovoltaic module is simply fixed by the bolt, the frame of the photovoltaic module is deformed for a long time, and then the photovoltaic module is damaged, and the bolt is easily loosened to cause the connection to be not firm, and the risk of falling of the photovoltaic module is increased. SUMMARY

[0003] In order to solve the above problems, the utility model provides a photovoltaic module and support connecting device of anti-loose, which comprises a pressing piece, a connecting piece and a fixing piece.

[0004] The pressing piece and the connecting piece are connected, and the pressing piece is attached to the photovoltaic module.

[0005] The connecting piece and the photovoltaic module are fixed, and the connecting piece and the pressing piece form an assembly groove to assemble the photovoltaic module.

[0006] The fixing piece is connected with the connecting piece to form a fixing ring between the fixing piece and the connecting piece, and the fixing ring is connected with the flexible support.

[0007] The pressing piece is arranged on the basis of the bolt connection, and the upper part of the photovoltaic module is pressed to improve the stability, so that the hole of the frame is not stressed and twisted due to shaking, and the stability of the photovoltaic module is improved.

[0008] Further, the pressing piece, the connecting piece and the fixing piece are provided with connecting holes, and the connecting bolt passes through the connecting holes to connect the pressing piece, the connecting piece and the fixing piece.

[0009] The pressing piece, the connecting piece and the fixing piece can be fixed by a group of bolts, and the operation is simple and convenient to use.

[0010] Further, the connecting piece is provided with a first fixing hole, and the photovoltaic module is provided with a second fixing hole; the bolt passes through the first fixing hole and the second fixing hole to connect the connecting piece and the photovoltaic module.

[0011] Further, the fixing member is provided with an anti-loosening member at the connecting position with the connecting member, and the connecting member is provided with an anti-loosening member at the connecting position with the photovoltaic module.

[0012] The anti-loosening member is arranged at the bolt connection position to prevent the bolt from loosening due to shaking, so that the connection fastening is not affected by wind force, and the photovoltaic module is prevented from falling off.

[0013] Further, a limiting member is arranged between the bolt and the second fixing hole, and the limiting member is matched with the size of the bolt to prevent the bolt from rotating.

[0014] When the connecting member is mounted on the frame of the photovoltaic module, the distance between the hole of the photovoltaic module and the edge is far, so that the bolt rotates synchronously with the nut when the bolt and the nut are fastened, and finally the bolt cannot be firmly fixed. The limiting member can effectively prevent the bolt from rotating, so that the bolt and the nut are firmly connected.

[0015] Further, the anti-loosening member comprises an anti-loosening ring and an anti-loosening nut; the anti-loosening nut comprises a tooth surface, the anti-loosening ring is provided with a fastening tooth matched with the tooth surface, and the fastening tooth is inclined along the fastening direction of the anti-loosening nut to make the tooth surface clamped to prevent the anti-loosening nut from rotating reversely.

[0016] The nut is an anti-loosening nut, and the connecting member or the fixing member is provided with an anti-loosening ring. At this time, the fastening tooth and the tooth surface are matched, and the fastening tooth can only rotate along the inclined direction of the fastening tooth, that is, the fastening direction of the anti-loosening nut. When the anti-loosening nut reversely rotates, the fastening tooth and the tooth surface are clamped to block the anti-loosening nut from reversing, so that the connecting device and the photovoltaic module cannot be disassembled once connected, and the possibility of the anti-loosening nut reversing due to wind shaking is completely eliminated, and the photovoltaic module is prevented from falling off.

[0017] Further, the limiting member comprises a limiting groove, a groove wall and a through hole. The groove wall is oppositely arranged at two sides of the limiting groove to limit the bolt, and the limiting groove is provided with a through hole at the bottom. The bolt passes through the through hole and is matched with the second fixing hole.

[0018] The size of the limiting member depends on the distance between the hole of the photovoltaic module and the edge of the photovoltaic module frame. The limiting member needs to be in contact with the edge of the photovoltaic module, and the through hole is always aligned with the hole of the photovoltaic module to prevent the limiting member from rotating when the bolt rotates. Preferably, the contact surface between the limiting member and the photovoltaic module frame is rough to increase the friction between them and prevent the relative movement between the photovoltaic module and the limiting member.

[0019] Further, the pressing member is divided into a middle pressing member and a side pressing member. The middle pressing member is used to connect between two photovoltaic modules, and the two sides of the middle pressing member are matched with the connecting member to form an assembly groove. The side pressing member is used to connect with one photovoltaic module, and one side of the side pressing member is matched with the connecting member to form an assembly groove.

[0020] When the connection device is used to connect two photovoltaic modules, a medium-pressure component is used; when the connection device is connected to one side of a photovoltaic module, a side-pressure component is used.

[0021] Furthermore, the surface of the pressed component located in the assembly groove is provided with anti-slip texture; the anti-slip texture can be raised dots or blocks to increase the friction between the pressed component and the upper surface of the photovoltaic module, thereby further enhancing their stability.

[0022] Furthermore, the inner surface of the fixing ring is provided with a protrusion perpendicular to the extension direction of the flexible support; when the fixing ring and the flexible support are connected, the protrusion and the flexible support are interference-fitted.

[0023] The raised strips make the fastener and the flexible support more secure, reducing the probability of relative movement.

[0024] Furthermore, the anti-loosening ring and the connector are detachably connected. The anti-loosening ring has a locking claw on the surface opposite to the fastening teeth, and the locking claw engages with the first fixing hole.

[0025] When the photovoltaic modules need to be disassembled from the flexible support, the locking claws can be broken to allow the anti-loosening ring and the connecting plate to move relative to each other. Then, the anti-loosening nut and the anti-loosening ring can be unscrewed at the same time. When using them again, a new anti-loosening ring can be replaced, which is low-cost.

[0026] The beneficial effects of this utility model are as follows:

[0027] (1) The connection device of this utility model has higher connection stability, better resistance to wind force, reduced the swaying amplitude of photovoltaic modules, and reduced the risk of photovoltaic module frame distortion.

[0028] (2) The connection device of this utility model ensures that the bolts and nuts will not loosen due to wind swaying. The anti-loosening ring and anti-loosening nut work together to prevent the anti-loosening nut from turning back, thus avoiding the phenomenon of photovoltaic module connection falling off due to bolt loosening.

[0046] like Figures 1-10 The photovoltaic module and bracket connection device shown includes a pressing component 1, a connecting component 2, and a fixing component 3.

[0047] The pressing component 1 and the connecting component 2 are connected, and the pressing component 1 is attached to the photovoltaic module;

[0048] The connector 2 is fixed to the photovoltaic module, and the connector 2 and the pressing part 1 form an assembly groove 11 for assembling the photovoltaic module;

[0049] The fastener 3 and the connector 2 are connected to form a fixing ring 31 between the fastener 3 and the connector 2. The fixing ring 31 is connected to the flexible bracket.

[0050] A pressing component 1 is installed on the basis of bolt 43 connection to press the top of the photovoltaic module to improve its stability and prevent stress distortion at the holes of the frame due to shaking, thereby improving the stability of the photovoltaic module.

[0051] In one embodiment, such as Figures 1-2 The pressing component 1, connecting component 2, and fixing component 3 shown are all provided with connecting holes 15. Connecting bolts 43 pass through the connecting holes 15 to connect the pressing component 1, connecting component 2, and fixing component 3.

[0052] The pressing component 1, the connecting component 2, and the fixing component 3 can all be fixed by a set of bolts 43, which is simple to operate and convenient to use.

[0053] In a specific embodiment, as shown Figure 5 , 10 As shown, the connector 2 has a first fixing hole 21, and the photovoltaic module has a second fixing hole; the bolt 43 passes through the first fixing hole 21 and the second fixing hole to connect the connector 2 and the photovoltaic module.

[0054] In one specific embodiment, such as Figures 1-2 The pressing component 1 shown is divided into a middle pressing component 12 and a side pressing component 13. The middle pressing component 12 is used to connect between two photovoltaic modules, and both sides of the middle pressing component 12 form an assembly groove 11 with the connecting component 2. The side pressing component 13 is used to connect to the photovoltaic module on one side, and one side of the side pressing component 13 forms an assembly groove 11 with the connecting component 2.

[0055] When the connection device is used to connect two photovoltaic modules, the middle pressure member 12 is used; when the connection device is connected to one side of the photovoltaic module, the side pressure member 13 is used.

[0056] In one embodiment, such as Figures 1-2 The fastener 3 shown is provided with anti-loosening parts 4 at the connection position with the connector 2 and at the connection position with the photovoltaic module.

[0057] Anti-loosening component 4 is installed at the bolt 43 connection to prevent the bolt 43 from loosening due to shaking, so that the connection tightness is not affected by wind force and the photovoltaic module is prevented from falling off.

[0058] In one specific embodiment, such as Figure 8 The anti-loosening component 4 shown includes an anti-loosening ring 41 and an anti-loosening nut 42; the anti-loosening nut 42 includes a toothed surface 421, and the anti-loosening ring 41 is provided with fastening teeth 411 that cooperate with the toothed surface 421. The fastening teeth 411 are inclined along the fastening direction of the anti-loosening nut 42 so as to engage with the toothed surface 421 to prevent the anti-loosening nut 42 from rotating in the opposite direction.

[0059] The nut is a lock nut 42; at the same time, the connector 2 or the fixing part 3 is provided with a lock ring 41; at this time, the fastening teeth 411 and the tooth surface 421 cooperate, and can only rotate in the inclined direction of the fastening teeth 411, that is, the fastening direction of the lock nut 42. When the lock nut 42 wants to rotate in the opposite direction, the fastening teeth 411 and the tooth surface 421 will be stuck to prevent the lock nut 42 from rotating in reverse. Therefore, once the connecting device and the photovoltaic module are connected, they cannot be removed, completely eliminating the possibility of the lock nut 42 rotating in reverse due to wind swaying, and preventing the photovoltaic module from falling off.

[0060] In one embodiment, such as Figure 10 A limiting member 5 is provided between the bolt 43 and the second fixing hole. The limiting member 5 is adapted to the size of the bolt 43 to prevent the bolt 43 from rotating.

[0061] When installing the connector 2 and the frame of the photovoltaic module, some of the holes of the photovoltaic module are far from the edge, which causes the bolt 43 to rotate synchronously with the nut when the bolt 43 and nut are tightened, making it impossible to securely fix them. After setting the limiter 5, the bolt 43 can be effectively prevented from rotating, so that the connection between the bolt 43 and the nut is firm.

[0062] In one specific embodiment, such as Figure 9 The limiting member 5 shown includes a limiting groove 51, a groove wall 52 and a through hole 53; the groove wall 52 is arranged opposite to the two sides of the limiting groove 51 to restrict the bolt 43, and the bottom of the limiting groove 51 is provided with a through hole 53, through which the bolt 43 passes and cooperates with the second fixing hole.

[0063] The size of the limiting member 5 depends on the distance between the hole in the photovoltaic module frame and the edge of the photovoltaic module. The limiting member 5 needs to be in contact with the edge of the photovoltaic module. The through hole 53 is always aligned with the hole in the photovoltaic module to prevent the limiting member 5 from rotating when the bolt 43 rotates. Preferably, the contact surface between the limiting member 5 and the photovoltaic module frame is a rough surface to increase the friction between them and prevent relative movement between the photovoltaic module and the limiting member 5.

[0064] In one embodiment, such as Figures 3-4 The surface of the pressing component 1 located at the assembly groove 11 is provided with anti-slip texture 14; the anti-slip texture 14 can be protruding points or blocks to increase the friction between the pressing component 1 and the upper surface of the photovoltaic module, and further enhance the stability of the two.

[0065] In one embodiment, such as Figure 6 The inner surface of the fixed ring 31 shown is provided with a protrusion 32 perpendicular to the extension direction of the flexible support; when the fixed ring 31 and the flexible support are connected, the protrusion 32 and the flexible support are interference fit.

[0066] The protrusion 32 makes the fixation between the fastener 3 and the flexible bracket more secure, reducing the probability of their relative movement.

[0067] In one embodiment, such as Figure 7 The anti-loosening ring 41 and the connector 2 shown are detachably connected. The anti-loosening ring 41 has a locking claw 412 on the surface opposite to the fastening teeth 411. The locking claw 412 engages with the first fixing hole 21.

[0068] When the photovoltaic module needs to be disassembled from the flexible support, breaking the locking claw 412 allows the anti-loosening ring 41 and the connecting plate to move relative to each other, so that the anti-loosening nut 42 and the anti-loosening ring 41 can be unscrewed at the same time. When it is used again, a new anti-loosening ring 41 can be replaced, which is low-cost.

[0069] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0070] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0071] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
