In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] In order to better understand the technical solutions of the present application, the following will be described in conjunction with the accompanying drawings Figures 1 to 5 The positioning device and the tightening device in the embodiments of the present application are described.

[0030] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the tightening device in the embodiments of the present application for installing the photovoltaic support and the photovoltaic module is shown.

[0031] The tightening device 100 in the embodiments of the present application is used for tightening the to-be-installed member, which can be the photovoltaic support and the photovoltaic module 210.

[0032] The photovoltaic module 200 is used for collecting solar energy and can also convert solar energy into electric energy. In an example, the photovoltaic module 200 can include a single photovoltaic assembly 210. In another example, the photovoltaic module 200 can include multiple photovoltaic assemblies 210, and a photovoltaic support is used to connect the multiple photovoltaic assemblies 210 to form the photovoltaic module 200 and achieve support of the photovoltaic module 200. Taking an example of an example structure of the photovoltaic support, the photovoltaic support includes multiple connecting beams, which can specifically include purlins 300 and support beams, the purlins 300 are arranged on the support beams, and the purlins 300 and the support beams are connected by purlin brackets to form the photovoltaic support.

[0033] When the photovoltaic support connects multiple photovoltaic assemblies 210, the photovoltaic support is connected to the frame structure 220 of each photovoltaic assembly 210 through the purlin 300, so the to-be-mounted member can be specifically the frame structure 220 and the purlin 300, the frame structure 220 and the purlin 300 can be correspondingly provided with connecting holes, and the tightening device 100 is used to pass the locking assembly through the connecting holes of the frame structure 220 and the purlin 300, the locking assembly can be arranged as a bolt and a nut, or can be arranged in multiple forms such as a screw, a rivet, and a connecting pin, to achieve assembly and fixation of the photovoltaic support and the photovoltaic assembly 210.

[0034] It should be noted that the tightening device 100 can be used not only for connection and fixation between the photovoltaic support and the photovoltaic assembly 210, but also for installation between multiple components of the photovoltaic support, for example, connection between the purlin bracket and the support beam, the support beam and the purlin, or other mechanisms; the use of the tightening device 100 can also not be limited to the field of photovoltaic equipment, but can also be applied to other equipment that needs to be fastened. The present application does not make specific limitations here. For the convenience of description, the following will be described by taking the tightening device 100 as an example for connecting the purlin 300 and the frame structure 220 in the photovoltaic support and the photovoltaic assembly 210. Figure 1

[0035] Please refer to Figure 1 and Figure 2 , Figure 2 The figure shows the working principle of the positioning device 1 in the embodiment of the present application.

[0036] In the related scheme, the moving position of the tightening mechanism 2 is fixed, and taking the theoretical position of the connecting hole as an example, the target operation position is A1 position, the tightening device 100 will make the tightening mechanism 2 fixedly move to the A1 position, and by positioning the tightening mechanism 2 relative to the connecting holes on the photovoltaic support and the photovoltaic assembly 210, the reliable connection of the photovoltaic support and the photovoltaic assembly 210 can be achieved.

[0037] ​However, due to the large size of the photovoltaic support and the photovoltaic assembly 210, the absolute position of the connecting hole can vary greatly, and in the actual installation process, the actual position of the connecting hole can be at the B1 position, that is, there is a deviation between the theoretical position of the connecting hole and the actual position of the connecting hole, and at this time, the target operating position is the B1 position, and since the tightening device 100 in the related scheme only allows the tightening mechanism 2 to be fixedly moved to the A1 position, it is difficult to pass the locking assembly 400 through the connecting hole, and the automatic tightening cannot be achieved.

[0038] To solve the above problems, the application also provides a positioning device 1, which can adjust the position of the tightening mechanism 2 in real time according to the position of the photovoltaic support and the photovoltaic assembly 210 during automatic tightening by providing the positioning device 1 on the tightening device 100, so that the tightening mechanism 2 can accurately reach the target operating position to more reliably achieve the automatic tightening of the tightening device 100.

[0039] Please refer to Figures 1 to 4 , Figure 3 The structure of the tightening device 100 in the embodiment of the application is shown, Figure 4 The local enlarged view of the target operating position in the embodiment of the application is shown.

[0040] The positioning device 1 provided by the embodiment of the application comprises a bearing platform 11, a driving mechanism 12, and a positioning member 13. The bearing platform 11 comprises a first platform 111 and a second platform 112 rotatably installed on the first platform 111. The second platform 112 is used to bear the tightening mechanism 2. The driving mechanism 12 is used to drive the first platform 111 to move to drive the tightening mechanism 2 to move to the piece to be installed. The driving direction of the driving mechanism 12 intersects with the rotation axis of the second platform 112. The positioning member 13 is arranged on the second platform 112 or the tightening mechanism 2 and is configured to abut against at least a part of the piece to be installed to drive the second platform 112 to rotate relative to the first platform 111 to the relative position of the tightening mechanism 2 and the target operating position.

[0041] The positioning device 1 in the embodiment of the application can take the piece to be installed as a reference. When the driving mechanism 12 drives the first platform 111 to move to the relative position of the positioning member 13 on the second platform 112 and the piece to be installed, the second platform 112 can rotate relative to the first platform 111, and when the positioning member 13 moves to the limit moving position relative to the piece to be installed, the tightening mechanism 2 on the second platform 112 is in the relative position of the target operating position. Since the positioning member 13 is fixed at the limit moving position of the piece to be installed, the position of the positioning member 13 can be adjusted in real time according to the actual position of the piece to be installed by taking the piece to be installed as a reference, so that the tightening mechanism 2 can accurately reach the target operating position according to the relative position relationship between the positioning member 13 and the tightening mechanism 2, to more reliably achieve the automatic tightening of the tightening device 100.

[0042] It can be understood that when the to-be-installed member is the photovoltaic support and the photovoltaic component 210, since the purlin 300 of the photovoltaic support and the frame structure 220 of the photovoltaic component 210 are cross arranged, the limit moving position of the positioning member 13 relative to the to-be-installed member is the intersection of the purlin 300 and the frame structure 220. Therefore, in the design, the relative position relationship between the positioning member 13 and the tightening mechanism 2 can be designed according to the relative position relationship between the intersection of the purlin 300 and the frame structure 220 and the connecting hole, so that when the positioning member 13 moves to the limit moving position relative to the to-be-installed member, the tightening mechanism 2 on the second platform 112 is opposite to the target operation position, and the automatic searching of the target operation position is realized.

[0043] Specifically, the driving mechanism 12 includes a first stroke and a second stroke. When the driving mechanism 12 performs the first stroke, the driving mechanism 12 drives the first platform 111 to move in the first direction X until the positioning member 13 abuts against one of the purlin 300 and the frame structure 220. Then the driving mechanism 12 performs the second stroke, at this time, the second platform 112 rotates relative to the first platform 111, and the positioning member 13 moves along the straight edge of the purlin 300 or the frame structure 220. When the positioning member 13 moves to the intersection of the purlin 300 and the frame structure 220, i.e. the limit moving position of the positioning member 13 relative to the to-be-installed member, the tightening mechanism 2 can be opposite to the target operation position, so as to realize the automatic searching of the target operation position, and more reliably realize the automatic tightening of the tightening device 100.

[0044] The positioning device 1 in the embodiment of the application can realize the position adjustment of the tightening mechanism 2, no matter whether the target operation position is in the A1 position or the target operation position is in the B1 position, so as to more accurately guide the tightening mechanism 2 to the target operation position, reliably complete the insertion and tightening of the locking assembly 400, and improve the production efficiency.

[0045] Optionally, the positioning member 13 is used to abut against the purlin 300 or the frame structure 220. When the driving mechanism 12 performs the first stroke, the driving mechanism 12 can drive the first platform 111 to move towards the intersection of the purlin 300 and the frame structure 220, i.e. the first direction X is arranged obliquely relative to the extension direction of the purlin 300 and the extension direction of the frame structure 220, so as to improve the positioning efficiency.

[0046] The positioning member 13 can be arranged on the second platform 112 or the tightening mechanism 2. When the positioning member 13 is arranged on the second platform 112, the positioning member 13 protrudes from the second platform 112 towards the purlin 300 and the frame structure 220 by a certain distance, the protruding direction of the positioning member 13 is the second direction Z, and the second direction Z can be a vertical direction. The specific protruding distance of the positioning member 13 relative to the second platform 112 can be adjusted according to actual needs, that is, the positioning member 13 can abut against the purlin 300 and the frame structure 220.

[0047] In some optional embodiments, the first platform 111 and the second platform 112 are arranged in parallel, the driving direction of the driving mechanism 12 is parallel to the plane in which the first platform 111 is located, and the rotation axis of the second platform 112 is perpendicular to the plane in which the first platform 111 is located.

[0048] As an optional implementation, the driving direction of the driving mechanism 12 is the first direction X, and the extension direction of the rotation axis of the second platform 112 is the second direction Z, and the first direction X can be perpendicular to the second direction Z.

[0049] The above arrangement can make it more convenient for the second platform 112 to relatively rotate relative to the first platform 111 under the action of the driving mechanism 12 after the positioning member 13 abuts against the purlin 300 or the frame structure 220, so as to realize the alignment of the tightening mechanism 2 and the target operation position and improve the production efficiency.

[0050] Please refer to Figures 1 to 5 , Figure 5 FIG. 4 shows a structural schematic view of the positioning device 1 from another angle according to some embodiments of the present application.

[0051] In some optional embodiments, the positioning device 1 further comprises a limiting assembly 14 for limiting the limit rotation angle of the second platform 112.

[0052] Since the difference between the theoretical position of the connecting hole and the actual position of the connecting hole is usually small in the actual installation process, that is, the positioning device 1 is mainly used for fine adjustment of the position of the tightening mechanism 2 according to the actual position of the to-be-installed member, therefore, by arranging the limiting assembly 14 on the positioning device 1, the limit rotation angle of the second platform 112 can be limited, so as to fine adjust the position of the tightening mechanism 2 within the limit rotation angle, thereby improving the adjustment efficiency.

[0053] In addition, when connecting and fastening a plurality of target operation positions on a group of photovoltaic supports and photovoltaic components 210, or connecting and fastening target operation positions between a photovoltaic support and a plurality of photovoltaic components 210, the rotation angle of the second platform 112 does not need to be reset every time, thereby improving the production efficiency.

[0054] It can be understood that the limit rotation angle of the limiting assembly 14 can be adjusted according to the driving direction of the driving mechanism 12 and the specific structural size of the to-be-mounted member, that is, the adjusting efficiency can be improved while the tightening mechanism 2 can be more accurately moved to the target operating position.

[0055] In some embodiments, the limiting assembly 14 can also include a limiting sliding groove and a limiting block. For example, the limiting sliding groove can be arranged on the first platform 111 along the circumferential direction of the rotation axis of the second platform 112, and the second platform 112 is provided with a limiting block matched with the limiting sliding groove. The limiting block is embedded in the limiting sliding groove and can move relative to the limiting sliding groove, so as to limit the limit position of the limiting block through the limiting sliding groove, thereby limiting the limit rotation angle of the second platform 112.

[0056] In other embodiments, the limiting assembly 14 includes a limiting member 141 arranged on the second platform 112 and a limiting seat 142 fixed relative to the first platform 111. The limiting seat 142 has an adjustable limiting interval, and the limiting member 141 is arranged in the limiting interval.

[0057] That is, the limiting member 141 of the second platform 112 is arranged between the limiting seats 142 fixed relative to the first platform 111. By adjusting the limiting interval between the limiting seats 142 arranged opposite to each other, the limit rotation angle of the second platform 112 can be adjusted, so as to be applicable to different specifications of photovoltaic supports to be mounted with the photovoltaic module 210, and in addition, it can also be applicable to the installation between different parts of the photovoltaic support, thereby improving the applicability.

[0058] Of course, the limiting member 141 can be arranged on the first platform 111, and the limiting seat 142 can be arranged on the second platform 112. The limiting member 141 can extend between the limiting seats 142 arranged opposite to each other, so as to limit the limit rotation angle of the second platform 112 through the limiting assembly 14.

[0059] Taking the limiting assembly 14 including the limiting member 141 and the limiting seat 142 as an example, the limiting member 141 is arranged on the second platform 112, and the limiting seat 142 is arranged on the first platform 111.

[0060] As an optional implementation, the limiting member 141 is a protruding portion extending radially along the edge of the second platform 112. The limiting seat 142 includes two oppositely arranged supporting walls 1421, and two bolts 1422 are respectively threadedly connected to the two supporting walls 1421. The two bolts 1422 are coaxially arranged and spaced apart from each other to form a limiting interval, and the protruding portion is arranged between the two bolts 1422.

[0061] By setting the limiting seat 142 as a structure in which a bolt 1422 is threadedly connected to the supporting wall 1421, the protruding distance of the bolt 1422 relative to the supporting wall 1421 can be adjusted by rotating the bolt 1422, so as to realize the adjustment of the limit rotation angle of the second platform 112. By threadedly connecting a bolt 1422 to each of the two supporting walls 1421, the limit rotation angle on both sides of the second platform 112 can be adjusted respectively, thereby improving the flexibility of adjustment.

[0062] In some optional embodiments, the side surface of the positioning member 13 is set as an arc surface, and the positioning member 13 is configured to abut against the to-be-mounted member through the arc surface.

[0063] Compared with setting the side surface of the positioning member 13 as a planar structure, by setting the side surface of the positioning member 13 as an arc surface, the positioning member 13 can be more conveniently moved relative to the surface of the purlin 300 or the frame structure 220, the friction is reduced, the damage to the purlin 300 or the frame structure 220 is reduced, and the reliability is improved.

[0064] Further, the positioning member 13 is set as a cylindrical structure, and the positioning member 13 is rotationally connected to the second platform 112 or the mounting mechanism, so that when the driving mechanism 12 performs the second driving stroke, the positioning member 13 can be rotationally arranged relative to the purlin 300 or the frame structure 220, so as to reduce the friction between the positioning member 13 and the purlin 300 or the frame structure 220, further reduce the damage to the positioning member 13, the purlin 300 or the frame structure 220, and improve the service life of the positioning device 1.

[0065] Please refer to Figures 1 to 5 In some optional embodiments, the positioning device 1 further includes a base 15, the first platform 111 is slidingly connected to the base 15, and the driving mechanism 12 is arranged on the base 15 and is used to drive the first platform 111 to reciprocally move relative to the base 15.

[0066] Optionally, one of the base 15 and the first platform 111 is provided with a slide channel extending along the first direction X, and the other is provided with a slide groove matched with the slide channel, and the first platform 111 is slidingly connected to the base 15 along the first direction X through the slide channel.

[0067] As an optional implementation, the base 15 is arranged in parallel with the first platform 111 and the second platform 112, the base 15 is provided with a slide channel, and the first platform 111 is provided with a slide groove facing the surface of the base 15, so as to improve the stability of the first platform 111 during movement by matching the slide groove with the slide channel.

[0068] Optionally, the number of slide channels is two or more, and the two or more slide channels can be arranged in pairs on both sides of the driving mechanism 12, so as to further improve the reliability of the first platform 111 during sliding.

[0069] In some optional embodiments, the driving mechanism 12 comprises a fixed end and a movable end, the fixed end is connected to the base 15. In the overlapping area of the first platform 111 and the second platform 112, the second platform 112 is provided with a through hole exposing the first platform 111, and the positioning device 1 further comprises an adapter 16, the movable end of the driving mechanism 12 extends to the through hole and is connected to the first platform 111 through the adapter 16.

[0070] By providing the through hole in the overlapping area of the second platform 112 and the first platform 111, and connecting the movable end of the driving mechanism 12 to the overlapping area of the second platform 112 and the first platform 111, the space occupied by the positioning device 1 along the first direction X can be reduced on the basis of the same driving distance, thereby reducing the space required by the tightening device 100, so as to be suitable for the tightening of the to-be-installed member in a narrow space, and improve the applicability of the tightening device 100.

[0071] Optionally, the driving mechanism 12 can comprise at least one of an electric push rod, a ball screw mechanism, a hydraulic cylinder, an electric cylinder, etc.

[0072] As an optional implementation, the through hole is arranged at the rotation center area of the second platform 112. Since the greater the distance between the through hole and the fixed end of the driving mechanism 12 along the first direction X, the smaller the space occupied by the positioning device 1 along the first direction X on the basis of the same driving distance, by arranging the through hole at the rotation center area of the second platform 112, the space occupied by the positioning device 1 along the first direction X can be reduced while avoiding the interference between the movable end of the driving member and other components on the second platform 112, further improving the applicability of the tightening device 100.

[0073] In some optional embodiments, the positioning member 13 has a first distance from the tightening device, and has a second distance from the rotation center of the second platform 112, the second distance is greater than the first distance. It can be understood that the first distance is determined by the relative distance between the intersection of the purlin 300 and the frame structure 220 and the connecting hole, and by making the second distance greater than the first distance, the accuracy of the adjustment of the tightening mechanism 2 can be improved, so that the tightening mechanism 2 can be more accurately positioned relative to the target operation position, and the installation effect is improved.

[0074] In some optional embodiments, the tightening mechanism 2 comprises a first tightening structure 21 mounted on the second platform 112 and a second tightening structure 23 arranged above the first tightening structure 21 through a lifting mechanism 22, the locking assembly 400 comprises a first fastener 410 and a second fastener 420, the first tightening structure 21 is used to connect the first fastener 410, and the second tightening structure 23 is used to connect the second fastener 420.

[0075] The first tightening structure 21 and the second tightening structure 23 are matched to tighten the locking assembly 400 in the connecting hole to realize the connection between the photovoltaic support and the photovoltaic assembly 210.
