Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic devices, in particular to a photovoltaic support frame. BACKGROUND

[0002] The photovoltaic support frame is an important component in the photovoltaic power generation system, which mainly provides a stable and reliable installation and support environment for the photovoltaic panel, ensures the normal operation of the photovoltaic panel under various natural conditions, and meets the long-term use requirements. However, in the face of the growing demand for photovoltaic panel installation and the requirement for convenient maintenance, the traditional support frame design gradually shows its shortcomings.

[0003] In the prior art, in order to realize the connection between the photovoltaic panel and the support frame, a bolt fixing method is usually adopted. Specifically, corresponding threaded holes are pre-set on the photovoltaic panel and the support frame, and the two are tightly connected by bolts. Although this connection method can meet the basic installation requirements, in actual application, there are problems of complicated disassembly and assembly process and low efficiency. Especially in the process of large-scale photovoltaic power station construction and later maintenance, frequent disassembly and assembly operations require a lot of manpower and material resources. Therefore, how to simplify the disassembly and assembly process of the photovoltaic panel and improve the construction efficiency has become a technical problem to be solved. SUMMARY

[0007] By adopting the technical scheme, when the photovoltaic panel is installed, the hanging fastener of the mounting frame is aligned with the hanging position of the base frame, and a certain pushing force is applied to the mounting frame, so that the hanging position of the base frame enters the inlet and outlet of the hanging area, at this time, the hanging position of the base frame can force the limiting portion to deform through the guide portion, so as to expand the inlet and outlet of the hanging area. When the hanging position of the base frame enters the hanging area, the limiting portion restores the deformation, so that the mounting frame provided with the photovoltaic panel is connected to the base frame through the hanging fastener. When disassembling, only a certain pulling force needs to be applied to the mounting frame, so that the mounting frame and the base frame are separated, which greatly improves the convenience of disassembling and assembling the photovoltaic panel, and improves the construction efficiency of the overall structure.

[0008] Optionally, the limiting portion is gradually inclined towards the mounting frame from one end close to the connecting portion to the other end away from the connecting portion, and the guide portion is gradually inclined away from the mounting frame from one end close to the limiting portion to the other end away from the limiting portion.

[0009] By adopting the technical scheme, the inlet and outlet of the hanging area are reduced, so that the hanging position of the base frame can be buckled in the hanging area.

[0010] Optionally, the connecting portion of the limiting portion and the guide portion forms a linking portion, the surface of the linking portion close to the mounting frame is provided with a protruding block, and the surface of the linking portion away from the mounting frame is provided with a deformation groove.

[0014] Optionally, the surface of the limiting part away from the hanging area is provided with an abutting piece, one end of the abutting piece extends to the outside of the limiting end of the limiting groove, so that the limiting column abuts against the abutting piece; when the limiting column pushes the abutting piece, the abutting piece forces the one end of the limiting part away from the connecting part to swing towards the surface close to the mounting rack.

[0015] By adopting the technical scheme, the hanging rod forces the limiting column to rotate to the limiting end of the limiting groove, at this time, the limiting column abuts against the abutting piece, if the mounting rack is directly pulled from outside to force the hanging rod to displace relative to the connecting part towards the inlet and outlet, the limiting column blocks the abutting piece, so that the hanging rod cannot be separated from the hanging area, the anti-theft performance of the mounting rack is improved (that is, when the mounting rack is forcibly detached, the limiting column needs to be rotated out of the limiting end of the limiting groove). In addition, if the limiting column is in the state of being located at the limiting end of the limiting groove, and the mounting rack is directly pulled, the limiting column can push the abutting piece, and the abutting piece can be forced to swing the one end of the limiting part away from the connecting part towards the surface close to the mounting rack to reduce the inlet and outlet of the hanging area, and further improve the connection stability between the mounting rack and the hanging rod.

[0026] In summary, the present application has at least one of the following beneficial technical effects:

[0027] 1. By arranging the hanging buckle, when the photovoltaic panel is installed, the hanging buckle of the mounting frame is aligned with the hanging part of the base frame, a certain pushing force is applied to the mounting frame, the hanging part of the base frame enters the inlet and outlet of the hanging area, at this time, the hanging part of the base frame can force the limiting part to deform to expand the inlet and outlet of the hanging area. When the hanging part of the base frame enters the hanging area, the limiting part restores the deformation, so that the mounting frame provided with the photovoltaic panel is connected to the base frame through the hanging buckle. When disassembling, only a certain pulling force needs to be applied to the mounting frame to force the mounting frame to separate from the base frame, thereby greatly improving the disassembly convenience of the photovoltaic panel and improving the construction efficiency of the overall structure;

[0028] 2. By arranging the limiting column, a certain pushing force is applied to the mounting frame to force the hanging rod of the base frame to buckle into the hanging area, and then the driving assembly is used to force the hanging rod to rotate by a certain angle to drive the limiting column of the hanging rod to rotate to the limiting end of the limiting slot, so that the limiting part is limited. When the mounting frame is pulled from outside, the limiting column forms an obstacle to the limiting part through the limiting end, that is, the mounting frame cannot be disassembled. When the mounting frame is forcibly disassembled, the limiting column needs to be rotated out of the limiting end of the limiting slot first, and then the mounting frame can be disassembled, thereby improving the connection stability of the mounting frame and improving the anti-theft performance of the mounting frame. Moreover, the limiting column is inserted into the limiting slot, which can limit the displacement of the mounting frame and reduce the possibility of displacement of the mounting frame along the axis of the hanging rod;

[0029] 3. By the setting of the tightening ring, a plurality of hanging rods are arranged on the base frame. When the mounting frame is hung on one of the hanging rods by the hanging buckle, at this time, the limiting column of the hanging rod close to the tightening ring on the base frame can pass through the through channel. When the plurality of hanging rods are driven to rotate synchronously, the limiting column of the hanging rod in the hanging area is driven to rotate to the limiting end of the limiting slot, at this time, the limiting column of the hanging rod close to the tightening ring is synchronously rotated and pulled to tighten the mounting frame by the tightening ring, thereby further improving the connection stability of the mounting frame.

[0050] Embodiment 3: The embodiment of the application discloses a photovoltaic support rack.

[0051] The photovoltaic support rack disclosed by the embodiment of the application is different from the embodiment 2 in that:

[0052] Referring to Figure 4 , Figure 5In the embodiment, each of the hanging rods 21 is rotationally connected with the base frame 2 to be able to rotate around the middle axis thereof, and the outer peripheral wall of each of the hanging rods 21 is fixedly installed with a limiting post 211. The connecting portion 31 of the hanging buckle 3 is provided with a limiting slot 37 through which the limiting post 211 passes, and one end of the limiting slot 37 extends to the limiting portion 32. For the convenience of description, the one end of the limiting slot 37 close to the limiting portion 32 is defined as the limiting end 371 of the limiting slot 37. The base frame 2 is provided with a driving assembly 4, and the driving assembly 4 is used to drive all the hanging rods 21 to rotate synchronously to force the limiting post 211 to rotate to the limiting end 371 of the limiting slot 37.

[0053] The outer side wall of the base frame 2 is provided with a mounting slot 22, and the driving assembly 4 comprises a driving disc 41, a force applying rod 42 and a synchronizer. One end of one of the hanging rods 21 extends into the mounting slot 22 and is coaxially fixed with the driving disc 41. The outer peripheral wall of the driving disc 41 is fixedly installed with a force applying strip 43, and the side wall of the force applying strip 43 is provided with a sliding slot 431. The length direction of the force applying rod 42 is consistent with the length direction of the hanging rod 21, and the force applying rod 42 is arranged in the sliding slot 431 to be able to slide along the length direction of the hanging rod 21.

[0054] Referring to Figure 5 The inner wall of the mounting slot 22 is respectively provided with a first limiting hole 221 and a second limiting hole 222, and the first limiting hole 221 and the second limiting hole 222 are both used for the threaded insertion of the force applying rod 42. When the force applying rod 42 is threadedly connected to the first limiting hole 221, the limiting post 211 of the hanging rod 21 rotates to the one end of the limiting slot 37 close to the connecting portion 31. When the force applying rod 42 is threadedly connected to the second limiting hole 222, the limiting post 211 of the hanging rod 21 rotates to the limiting end 371 of the limiting slot 37. The synchronizer is a belt (not shown in the figure), which is arranged around all the hanging rods 21 to drive all the hanging rods 21 to rotate synchronously.

[0055] It should be noted that a cover plate (not shown in the figure) is installed at the slot opening of the mounting slot 22, one side of the cover plate is hingedly connected to the inner wall of the mounting slot 22, and the cover plate is provided with an anti-theft lock (the anti-theft lock is a prior art structure, and its structure will not be described in detail here, and it is not shown in the figure). In this way, the cover plate is locked by the anti-theft lock, thereby reducing the private rotation operation of the driving disc 41 by irrelevant personnel from outside.

[0056] In the embodiment, in order to ensure that the limiting column 211 can penetrate into the limiting groove 37 when the hanging buckle 3 of the mounting rack 1 is buckled to the hanging rod 21, an identification scale line (not shown in the figure) can be arranged on the outer peripheral wall of the hanging rod 21, and when the limiting column 211 penetrates into the limiting groove 37, the identification scale line is located at the side edge of the mounting strip 14. In this way, the arrangement of the identification scale line facilitates the observation of the installer, so that when the hanging buckle 3 of the mounting rack 1 is buckled to the hanging rod 21, the limiting column 211 can penetrate into the limiting groove 37.

[0057] The implementation principle of the embodiment 3 of the application is that a certain pushing force is applied to the mounting rack 1 to force the hanging rod 21 of the base frame 2 to buckle into the hanging area 34, then drive the hanging rod 21 to rotate by a certain angle, drive the limiting column 211 of the hanging rod 21 to rotate to the limiting end 371 of the limiting groove 37, thereby limiting the limiting part 32, and finally lock the slot opening of the mounting groove 22 through the cover plate. When an unrelated person outside pulls the mounting rack 1, the limiting column 211 hinders the limiting part 32, that is, the mounting rack 1 cannot be detached, and when the mounting rack 1 is forcibly required to be detached, the limiting column 211 needs to be rotated out of the limiting end 371 of the limiting groove 37 first, and then the mounting rack 1 can be detached, thereby improving the connection stability of the mounting rack 1 and improving the anti-theft performance of the mounting rack 1. Moreover, the limiting column 211 is inserted into the limiting groove 37, which can limit the displacement of the mounting rack 1 to a certain extent, thereby reducing the possibility of displacement of the mounting rack 1 along the axis of the hanging rod 21.

[0058] Embodiment 4: The embodiment of the application discloses a photovoltaic support frame.

[0059] The photovoltaic support frame disclosed by the embodiment of the application is different from the embodiment 3 in that:

[0060] Referring to Figure 6 , Figure 7 In the embodiment, the limiting part 32 is fixedly installed with an abutting piece 38 away from the surface of the hanging area 34, the abutting piece 38 is installed on the surface of the limiting part 32 in a welding manner, one end of the abutting piece 38 extends to the outside of the limiting end 371 of the limiting groove 37, and an abutting groove 381 is formed in the end of the abutting piece 38 away from the limiting part 32, the abutting groove 381 is arranged in an arc shape to embed the outer peripheral wall of the limiting column 211; when the limiting column 211 pushes the abutting piece 38, the abutting piece 38 forces the end of the limiting part 32 away from the connecting part 31 to swing towards the surface of the mounting rack 1.

[0061] The implementation principle of the embodiment 4 of the present application is that after the hanging rod 21 is buckled into the hanging area 34, the hanging rod 21 is driven to rotate to force the limiting column 211 to rotate to the limiting end 371 of the limiting groove 37, so that the limiting column 211 is embedded into the abutting groove 381 of the abutting piece 38. On the one hand, the abutting groove 381 can limit the displacement of the hanging buckle 3, and reduce the possibility that the mounting rack 1 is free to slide along the length direction of the hanging rod 21 after the mounting rack 1 is buckled to the hanging rod 21. On the other hand, if an irrelevant person in the outside world wants to directly pull the mounting rack 1 to force the hanging rod 21 to be separated from the hanging area 34, the limiting column 211 can push the abutting piece 38, and the abutting piece 38 subjected to the pushing force can swing the limiting part 32 away from one end of the connecting part 31 towards the surface close to the mounting rack 1 to reduce the inlet and outlet 35 of the hanging area 34, further improve the connection stability between the mounting rack 1 and the hanging rod 21, and further improve the anti-theft performance of the overall structure.

The tightening ring 5 is annular and forms a penetrating passage 51 for the limiting column 211 to penetrate, and the tightening ring 5 and the hanging buckle 3 are spaced apart along the length direction of the mounting strip 14.

[0065] The hinged part of the swing strip 6 and the inner wall of the avoiding groove 141 is provided with a first elastic member, which forces the swing strip 6 to turn into the avoiding groove 141 under normal circumstances, and the swing strip 6 swings to be parallel to the surface of the mounting rack 1, and the first elastic member is a first torsional spring (not shown in the figure). The hinged part of the connecting rod 52 and the free end of the swing strip 6 is provided with a second elastic member, which forces the penetrating passage 51 of the tightening ring 5 to face the hanging area 34 under normal circumstances, and the second elastic member is a second torsional spring (not shown in the figure).
