[0033] When the distance between the bent portion and the second bent plate is zero, the effect of reducing the negative wind shedding of the photovoltaic module is improved. When the distance between the bent portion and the second bent plate is greater than zero, there is a certain distance between the bent portion and the second bent plate, reducing the matching accuracy between the photovoltaic module hanger and the purlin, which is beneficial for hanging the photovoltaic module on the purlin by an installation robot.

[0034] The above description is only an overview of the technical solution of the present invention. In order to be able to understand the technical means of the present invention more clearly, it can be implemented according to the content of the specification.

DETAILED DESCRIPTION

[0051] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0052] When installing a photovoltaic module, it is usually manually carried and laid on a photovoltaic support. Then, bolts and nuts are installed to achieve the firm connection between the photovoltaic module and the photovoltaic support. During the process of manually carrying the photovoltaic module and laying it on the photovoltaic support, the installer needs to first carry the photovoltaic module from the ground to below the purlin in the photovoltaic support. Then, the installer holds both sides of the long border of the photovoltaic module with both hands and delivers it to the installer on the scaffold. After receiving the photovoltaic module, the installer on the scaffold lays the photovoltaic module above the purlin.

[0053] However, during the installation of bolts and nuts, one installer needs to hold the photovoltaic module first, and then another installer can install the bolts and nuts. The installation process is complex, the installation efficiency is low, and two installers are required to complete the installation of bolts and nuts. To solve the above problems, an embodiment of the present utility model provides a photovoltaic module hook and a photovoltaic system.

[0054] In a first aspect, an embodiment of the present utility model discloses a photovoltaic module hook 1, and the structure of the photovoltaic module hook 1 has the following embodiments.

[0055] Embodiment 1

[0056] Referring to Figures 1 to 4 , the photovoltaic module hook 1 includes: a connecting portion 11 having a receiving groove 111 extending in a first direction, and the receiving groove 111 is used to cooperate with the bottom plate 21 at the bottom of the middle border 2 of the photovoltaic module; a baffle portion 12 connected to one end of the connecting portion 11, and the baffle portion 12 is used to be hooked to the purlin 3; a gasket portion 14 connected to the connecting portion 11, the gasket portion 14 is located on one side of the connecting portion 11 along a second direction, the second direction intersects with the first direction, and a through hole 141 is provided on the gasket portion 14.

[0057] The photovoltaic module hook 1 is used to realize the hooking connection between the photovoltaic module and the purlin 3. The photovoltaic module includes a photovoltaic laminate and four borders 2, and the four borders 2 include two long borders and two short borders. The photovoltaic module hook 1 is specifically connected to the long border. Referring to Figure 3 , the photovoltaic module hooks 1 connected to the two long borders can be symmetrically arranged.

[0058] The first direction can be the width direction of the photovoltaic module hook 1, and the first direction can be referred to the direction shown by the A arrow in Figure 1 . The second direction can be the length direction of the photovoltaic module hook 1, and the second direction can be referred to the direction shown by the B arrow in Figure 1 . The second direction is preferably perpendicular to the first direction. The receiving groove 111 preferably penetrates the connecting portion 11 along the second direction. The baffle portion 12 is preferably located on one side of the connecting portion 11 along a third direction, and the third direction can be the height direction of the photovoltaic module hook 1, and the third direction is preferably perpendicular to the first direction and the second direction.

[0059] The groove thickness of the receiving groove 111 is determined according to the thickness of the bottom plate 21. The fitting manner between the receiving groove 111 and the bottom plate 21 can be an interference fit. Through the setting of the receiving groove 111, the connection between the photovoltaic module hook 1 and the frame 2 can be quickly realized, and no other connecting parts need to be set.

[0060] The connecting portion 11 may include an upper plate portion 112, a bending portion 113 and a lower plate portion 114 connected to each other. At this time, the gasket portion 14 is connected to the upper plate portion 112. The surface of the gasket portion 14 away from the lower plate portion 114 is preferably flush with the surface of the upper plate portion 112 away from the lower plate portion 114, and the surface of the gasket portion 14 close to the lower plate portion 114 is preferably flush with the surface of the upper plate portion 112 close to the lower plate portion 114.

[0061] The gasket portion 14 is used to contact the bottom plate 21. An installation hole 211 is formed in the bottom plate 21, and the position of the through hole 141 corresponds to the position of the installation hole 211. The shape of the through hole 141 is preferably the same as the shape of the installation hole 211. When the frame 2 and the purlin 3 are fastened by the connecting bolt 4 and the nut, the gasket portion 14 functions as a gasket. At this time, no additional gasket needs to be installed, improving the installation efficiency.

[0062] It should be noted that after the photovoltaic module hook 1 is connected to the frame 2, the through hole 141 has been pre-aligned with the installation hole 211. The shape of the through hole 141 can be any one of a waist shape, a circular shape, and a rectangular shape. At this time, the structure of the through hole 141 is simple and easy to process. The shape of the through hole 141 is preferably a waist shape.

[0063] The frame 2 includes a bottom plate 21. The receiving groove 111 in the connecting portion 11 is specifically used to cooperate with the bottom plate 21 in the frame 2. The purlin 3 can be of a C shape. At this time, the purlin 3 includes a connected top plate 31 and a first bending plate 32. The top plate 31 contacts the frame 2, and the first bending plate 32 is located on one side of the top plate 31 along the width direction of the purlin 3. The baffle portion 12 is specifically used to be hung on the first bending plate 32 in the purlin 3. When the photovoltaic module hook 1 cooperates with the frame 2 and the purlin 3, the baffle portion 12 contacts the first bending plate 32. The height direction of the purlin 3 can be referred to Figure 2 the direction shown by the C arrow in

[0064] When installing the photovoltaic module, first connect the photovoltaic module hook 1 to the frame 2 in the photovoltaic module, then manually or an installation robot grabs the photovoltaic module connected with the photovoltaic module hook 1, and hangs the photovoltaic module on the purlin 3, and finally installs the connecting bolt 4 and the nut. Among them, after the photovoltaic module is hung on the purlin 3, the baffle portion 12 in the photovoltaic module hook 1 contacts the purlin 3. The nut can be a separate connecting nut 5. The nut can also be a pre-installed nut 16 provided on the photovoltaic module hook 1.

[0065] In the embodiment of the present utility model, the photovoltaic module hanger 1 can be used to hang the photovoltaic module on the purlin 3. After the photovoltaic module is hung on the purlin 3, the photovoltaic module is not likely to shift or slip greatly, so the installer does not need to hold the photovoltaic module first, and then the connecting bolts 4 and nuts can be installed, thereby improving the installation efficiency of the photovoltaic module. In addition, only one installer is required to install the connecting bolts 4 and nuts, compared with the prior art where two installers are required to install the bolts and nuts, which reduces the labor cost. In addition, after the photovoltaic module is connected to the photovoltaic module hanger 1, the photovoltaic module connected with the photovoltaic module hanger 1 can be hung on the purlin 3 by an installation robot, which reduces the labor intensity of the personnel and improves the installation efficiency of the photovoltaic module. In addition, the installer who originally held the photovoltaic module can install the connecting bolts 4 and nuts simultaneously with another installer, thereby improving the installation efficiency of the photovoltaic module.

[0066] The photovoltaic module hanger 1 further includes a bending portion 13 connected to one end of the baffle portion 12 away from the connecting portion 11, and the bending portion 13 extends toward the through hole 141.

[0067] The purlin 3 may further include a second bending plate 33 connected to the first bending plate 32. The first bending plate 32 and the second bending plate 33 form an L shape. The baffle portion 12 is specifically used for hanging on the first bending plate 32 in the purlin 3. When the photovoltaic module hanger 1 cooperates with the frame 2 and the purlin 3, the baffle portion 12 contacts the first bending plate 32, and the bending portion 13 is located on the side of the second bending plate 33 away from the top plate 31. Along the height direction of the purlin 3, the distance between the bending portion 13 and the second bending plate 33 is greater than or equal to zero and less than or equal to the height of the first bending plate 32. When the distance between the bending portion 13 and the second bending plate 33 is zero, the bending portion 13 contacts the second bending plate 33. Through the arrangement of the bending portion 13, the probability of the photovoltaic module falling off due to negative wind is reduced.

[0068] A positioning convex portion 15 protruding toward the bending portion 13 is provided on the gasket portion 14. The positioning convex portion 15 is located on the side of the through hole 141 close to the connecting portion 11. An installation hole 211 is formed on the frame 2, and the positioning convex portion 15 is used to extend into the installation hole 211 and contact the inner wall of the installation hole 211.

[0069] Specifically, when the shape of the through hole 141 is waist-shaped, the positioning convex portion 15 is located on one side of the length direction of the through hole 141, and the positioning convex portion 15 is close to the connecting portion 11. When the shape of the installation hole 211 is waist-shaped, the positioning convex portion 15 specifically contacts the inner wall of one side of the installation hole 211 along its length direction. When the positioning convex portion 15 contacts the inner wall of the installation hole 211, the photovoltaic module hanger 1 is installed in place. At this time, the position of the through hole 141 corresponds to the position of the installation hole 211.

[0070] During the connection process of the photovoltaic module hook 1 and the frame 2, the positioning of the photovoltaic module hook 1 can be achieved through the positioning convex portion 15, so as to ensure that the position of the through hole 141 corresponds to the position of the mounting hole 211. In addition, through the setting of the positioning convex portion 15, the sliding of the photovoltaic module can also be avoided.

[0071] The connecting portion 11 includes a connected upper plate portion 112, a bending portion 113, and a lower plate portion 114. The upper plate portion 112, the bending portion 113, and the lower plate portion 114 enclose a receiving groove 111, and the baffle portion 12 is connected to the lower plate portion 114. The receiving groove 111 includes a notch disposed opposite to the bending portion 113. Through the setting of enclosing the receiving groove 111 by the upper plate portion 112, the bending portion 113, and the lower plate portion 114, the contact area between the receiving groove 111 and the bottom plate 21 is increased, so as to ensure the matching performance between the receiving groove 111 in the photovoltaic module hook 1 and the bottom plate 21.

[0072] The cross-sectional shape of the lower plate portion 114 is trapezoidal. Along the second direction, the lower plate portion 114 has a first end far from the baffle portion 12 and a second end close to the baffle portion 12. Along the first direction, the width of the first end of the lower plate portion 114 is smaller than the width of the second end of the lower plate portion 114; the first end of the lower plate portion 114 is located on the side of the positioning convex portion 15 close to the bending portion 113 along the first direction.

[0073] The cross-section of the lower plate portion 114 is the section of the lower plate portion 114 perpendicular to the height direction of the photovoltaic module hook 1. When the photovoltaic module hook 1 is installed on the frame 2, the photovoltaic module hook 1 can be rotated first, so that the end of the gasket portion 14 far from the connecting portion 11 approaches the bottom plate 21 of the frame 2, and the end of the connecting portion 11 far from the gasket portion 14 is far from the bottom plate 21 of the frame 2. Then, the positioning convex portion 15 is first inserted into the mounting hole 211, and then the photovoltaic module hook 1 is rotated, so that the connecting portion 11 gradually approaches the bottom plate 21 of the frame 2 until the bottom plate 21 extends into the receiving groove 111. Through the setting that the first end of the lower plate portion 114 is located on the side of the positioning convex portion 15 close to the bending portion 113 along the first direction, it can be ensured that during the process of the positioning convex portion 15 being inserted into the mounting hole 211, the first end of the lower plate portion 114 is outside the bottom plate 21, which is beneficial to the positioning convex portion 15 being inserted into the mounting hole 211, and thus beneficial to the installation of the photovoltaic module hook 1. In addition, when the cross-sectional shape of the lower plate portion is trapezoidal, the connection width between the lower plate portion 114 and the baffle portion 12 is increased.

[0074] In the first embodiment, an avoidance groove 121 may be formed on the baffle portion 12, or the avoidance groove 121 may not be formed on the baffle portion 12. When the avoidance groove 121 is formed, the avoidance groove 121 communicates with the accommodation groove 111, and the avoidance groove 121 is located on a side of the accommodation groove 111 close to the bending portion 13. Along the first direction, the width of the avoidance groove 121 is smaller than the width of the connecting portion 11. Specifically, the avoidance groove 121 is formed at one end of the baffle portion 12 close to the connecting portion 11. Through the arrangement of the avoidance groove 121, when the photovoltaic module hook 1 in the first to third embodiments is installed on the frame 2, the baffle portion 12 can be prevented from hitting the frame 2.

[0075] In the first embodiment, the assembly process of the photovoltaic module hook 1 and the frame 2 may be as follows: The photovoltaic module hook 1 may be rotated first so that one end of the gasket portion 14 away from the connecting portion 11 approaches the bottom plate 21 of the frame 2, and one end of the connecting portion 11 away from the gasket portion 14 is away from the bottom plate 21 of the frame 2. Then, the positioning convex portion 15 is first inserted into the mounting hole 211, and then the photovoltaic module hook 1 is rotated so that the connecting portion 11 gradually approaches the bottom plate 21 of the frame 2 until the bottom plate 21 extends into the accommodation groove 111. Then, the photovoltaic module hook 1 is pushed toward the frame 2 until the accommodation groove 111 is completely embedded in the bottom plate 21.

[0076] The second embodiment

[0077] Referring to Figure 5 and Figure 6 , the difference between the second embodiment and the first embodiment is that: the cross-sectional shape of the lower plate portion 114 is rectangular, and the lower plate portion 114 is located on a side of the positioning convex portion 15 close to the bending portion 113 along the first direction.

[0078] In the second embodiment, the assembly process of the photovoltaic module hook 1 and the frame 2 may be as follows: The assembly process of the photovoltaic module hook 1 and the frame 2 may be as follows: The photovoltaic module hook 1 may be rotated first so that one end of the gasket portion 14 away from the connecting portion 11 approaches the bottom plate 21 of the frame 2, and one end of the connecting portion 11 away from the gasket portion 14 is away from the bottom plate 21 of the frame 2. Then, the positioning convex portion 15 is first inserted into the mounting hole 211, and then the photovoltaic module hook 1 is rotated so that the connecting portion 11 gradually approaches the bottom plate 21 of the frame 2 until the bottom plate 21 extends into the accommodation groove 111. Then, the photovoltaic module hook 1 is pushed toward the frame 2 until the accommodation groove 111 is completely embedded in the bottom plate 21.

[0079] In the second embodiment, an avoidance groove 121 is formed in the baffle portion 12. When the avoidance groove 121 is located on the side of the lower plate portion 114 away from the bending portion 113, the assembly process of the photovoltaic module hook 1 and the frame 2 can be as follows: First, make the avoidance groove 121 cooperate with the bottom plate 21. At this time, the positioning convex portion 15 is located above the bottom plate 21 and corresponds to the position of the mounting hole 211. Then, move the photovoltaic module hook 1 downward so that the gasket portion 14 contacts the bottom plate 21. At this time, the positioning convex portion 15 extends into the mounting hole 211 and is located on one side in the width direction of the waist-shaped mounting hole 211. Along the height direction of the frame 2, the bottom plate 21 corresponds to the position of the receiving groove 111. Then, push the photovoltaic module hook 1 toward the frame 2 until the receiving groove 111 is completely embedded in the bottom plate 21. At this time, the positioning convex portion 15 is located at the middle position of the waist-shaped mounting hole 211. Finally, along the length direction of the frame 2, adjust the position of the photovoltaic module hook 1 so that the positioning convex portion 15 contacts the side wall on one side in the length direction of the waist-shaped mounting hole 211.

[0080] Embodiment Three

[0081] Referring to Figure 7 and Figure 8 Embodiment Three is different from Embodiment Two in that a pre-installed nut 16 is provided on the gasket portion 14, and the position of the pre-installed nut 16 corresponds to the position of the through hole 141.

[0082] The connection manner between the pre-installed nut 16 and the gasket portion 14 can be welding. The pre-installed nut 16 has a threaded hole, and the position of the threaded hole corresponds to the position of the through hole 141. In this embodiment, only the connecting bolt 4 needs to be installed in the subsequent installation process, and there is no need to install a separate connecting nut 5, which further improves the installation efficiency of the photovoltaic module.

[0083] The assembly process of the photovoltaic module hook 1 and the frame 2 in Embodiment Three is the same as that of the photovoltaic module hook 1 and the frame 2 in Embodiment Two.

[0084] Embodiment Four

[0085] Referring to Figures 9 to 12 , the photovoltaic module hook 1 includes a connecting portion 11, a baffle portion 12, a bending portion 13, and a gasket portion 14. The connecting portion 11 has a receiving groove 111 extending in the first direction, and the receiving groove 111 is used to cooperate with the bottom plate 21 at the bottom of the frame 2 in the photovoltaic module.

The connecting portion 11 has a receiving groove 111 extending along the first direction, and the receiving groove 111 is used to cooperate with the bottom plate 21 at the bottom of the frame 2 of the photovoltaic module. The baffle portion 12 is connected to one end of the connecting portion 11, and the baffle portion 12 is used to hang with the purlin 3. The gasket portion 14 is connected to the connecting portion 11, and the gasket portion 14 is located on one side of the connecting portion 11 along the second direction, and a through hole 141 is provided on the gasket portion 14. The bending portion 13 is connected to one end of the baffle portion 12 away from the connecting portion 11, and the bending portion 13 extends toward the through hole 141.

[0091] In the fifth embodiment, the surface of the connecting portion 11 away from the gasket portion 14 and the surface of the baffle portion 12 away from the gasket portion 14 are in the same plane, and the surface of the connecting portion 11 close to the gasket portion 14 and the surface of the baffle portion 12 close to the gasket portion 14 are in the same plane. At this time, the gasket portion 14 is connected to the connecting portion 11 through the transition portion 17. The transition portion 17 is arranged at an angle with the gasket portion 14. Fillets are provided at the joints of the transition portion 17 with the gasket portion 14 and the connecting portion 11.

[0092] In the fifth embodiment, the thickness of the connecting portion 11 is equal to the thickness of the gasket portion 14. In this embodiment, the structure of the connecting portion 11 is simple and the processing difficulty is low.

[0093] A positioning convex portion 15 protruding towards the bending portion 13 is provided on the gasket portion 14. The positioning convex portion 15 is located on the side of the through hole 141 close to the connecting portion 11. An installation hole 211 is formed in the frame 2. The positioning convex portion 15 is used to extend into the installation hole 211 and contact the inner wall of the installation hole 211. An avoidance groove 121 is formed in the baffle portion 12. The avoidance groove 121 communicates with the accommodation groove 111, and the avoidance groove 121 is located on the side of the accommodation groove 111 close to the bending portion 13. Along the first direction, the width of the avoidance groove 121 is smaller than the width of the connecting portion 11. In the fifth embodiment, when the photovoltaic module hook 1 includes the positioning convex portion 15, if the avoidance groove 121 is not provided and only the accommodation groove 111 is provided, when the photovoltaic module hook 1 is inserted into the frame 2 in the width direction, the frame 2 will interfere with the positioning convex portion 15, resulting in abnormal installation of the photovoltaic module hook 1.

[0094] In the fifth embodiment, the installation of the photovoltaic module hook 1 is realized in a top-down manner. The assembly process of the photovoltaic module hook 1 and the frame 2 can be as follows: First, align the avoidance groove 121 with the bottom plate 21. At this time, the positioning convex portion 15 is located above the bottom plate 21 and corresponds to the position of the installation hole 211. Then, move the photovoltaic module hook 1 downward so that the gasket portion 14 contacts the bottom plate 21. At this time, the positioning convex portion 15 extends into the installation hole 211 and is located on one side in the width direction of the waist-shaped installation hole 211. Along the height direction of the frame 2, the bottom plate 21 corresponds to the position of the accommodation groove 111. Then, push the photovoltaic module hook 1 towards the frame 2 until the accommodation groove 111 is completely embedded in the bottom plate 21. At this time, the positioning convex portion 15 is located at the middle position of the waist-shaped installation hole 211. Finally, adjust the position of the photovoltaic module hook 1 along the length direction of the frame 2 so that the positioning convex portion 15 contacts the side wall on one side in the length direction of the waist-shaped installation hole 211.

[0095] In the second aspect, the embodiment of the present invention also discloses a photovoltaic system, including a photovoltaic module and a purlin 3. The above-mentioned photovoltaic module hook 1 is connected to the frame 2 of the photovoltaic module, and the photovoltaic module is hung on the purlin 3 through the photovoltaic module hook 1.

[0096] Since the photovoltaic system includes the above-mentioned photovoltaic module hanger, it also has the beneficial effects of the above-mentioned photovoltaic module hanger, which will not be elaborated here.

[0097] The assembly process of the photovoltaic module connected with the above-mentioned photovoltaic module hanger 1 and the purlin 3 is as follows: after the photovoltaic module is grabbed by a human or an installation robot, the bottom plate 21 of the frame 2 is attached to the top plate 31 in the purlin 3, and then the photovoltaic module drops. During the dropping process of the photovoltaic module, the photovoltaic module slides down by its own weight, so that the baffle part 12 contacts the first bending plate 32. At this time, the bending part 13 is located on the side of the first bending plate 32 away from the top plate 31; then, the installer passes the connecting bolt 4 through the through hole 141 in the photovoltaic module hanger 1, the installation hole 211 on the frame 2 and the through hole on the purlin 3, and cooperates the connecting nut 5 or the pre-installed nut 16 with the connecting bolt 4 and completes the tightening.

[0098] Refer to Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 11 , Figure 12 and Figure 14 , the purlin 3 includes a connected top plate 31 and a first bending plate 32, the photovoltaic module hanger 1 includes a baffle part 12, the baffle part 12 contacts the first bending plate 32, and along the height direction of the purlin 3, the height of the baffle part 12 is greater than or equal to the height of the first bending plate 32 and less than or equal to twice the height of the first bending plate 32.

[0099] The height direction of the purlin 3 can refer to the direction shown by the C arrow in Figure 2 . When the height of the baffle part 12 is greater than or equal to the height of the first bending plate 32, it can ensure the full contact between the baffle part 12 and the first bending plate 32, and further ensure that the photovoltaic module connected with the photovoltaic module hanger 1 is firmly hung on the purlin 3.

[0100] Refer to Figure 11 , the purlin 3 further includes a second bending plate 33 connected to the first bending plate 32, the photovoltaic module hanger 1 includes a bending part 13, and along the height direction of the purlin 3, the distance between the bending part 13 and the second bending plate 33 is greater than or equal to zero and less than or equal to the height of the first bending plate 32.

[0101] When the distance between the bending part 13 and the second bending plate 33 is zero, the bending part 13 contacts the second bending plate 33, improving the effect of reducing the negative wind shedding of the photovoltaic module. When the distance between the bending part 13 and the second bending plate 33 is greater than zero, there is a certain distance between the bending part 13 and the second bending plate 33, reducing the matching accuracy between the photovoltaic module hanger 1 and the purlin 3, facilitating the hanging of the photovoltaic module on the purlin 3 by an installation robot, and having a certain effect of reducing the negative wind shedding of the photovoltaic module.
