Description
Technical Field
[0001] This application relates to the technical field of photovoltaic equipment, and particularly to a photovoltaic support frame. Background Art
[0002] The photovoltaic support frame is an important part of the photovoltaic power generation system. Its main function is to provide a stable and reliable installation and support environment for the photovoltaic panels, ensure the normal operation of the photovoltaic panels under various natural conditions, and meet the requirements of long-term use. However, in the face of the increasing demand for photovoltaic panel installation and the requirement for convenient maintenance, the design of traditional support frames gradually shows deficiencies.
[0003] In the prior art, in order to connect the photovoltaic panel to the support frame, a bolt fixing method is usually adopted. Specifically, corresponding threaded holes are preset on the photovoltaic panel and the support frame, and the two are tightly connected by bolts. Although such a connection method can meet the basic installation requirements, in actual applications, there are problems of cumbersome disassembly and assembly processes and low efficiency. Especially in the construction and later maintenance of large-scale photovoltaic power stations, frequent disassembly and assembly operations require a large amount of manpower and material resources. Therefore, how to simplify the disassembly and assembly process of photovoltaic panels and improve the construction efficiency has become a technical problem to be solved urgently. Summary of the Invention
[0004] In order to improve the disassembly and assembly convenience of photovoltaic panels, this application provides a photovoltaic support frame.
[0005] The photovoltaic support frame provided by this application adopts the following technical solutions: A photovoltaic support frame includes an installation frame and a base frame. Among them, the installation frame has an installation station for installing photovoltaic panels. A hanging fastener is arranged on the side of the installation frame away from the installation station. The hanging fastener is elastically arranged for hanging the base frame; the hanging fastener includes a connecting part, a limiting part, and a guiding part which are integrally formed. One end of the connecting part is connected to the installation frame, and the other end is connected to the limiting part. One end of the limiting part away from the connecting part is connected to the guiding part; a hanging area is formed between the connecting part, the limiting part, and the installation frame. The guiding part and the surface of the installation frame are spaced apart to form an inlet and outlet of the hanging area.
[0006] By adopting the above technical solution, when installing the photovoltaic panel, align the hanging fastener of the mounting frame with the hanging part of the base frame, and apply a certain thrust to the mounting frame so that the hanging part of the base frame enters the entrance and exit of the hanging area. At this time, the hanging part of the base frame can force the limit part to deform through the guide part to expand the entrance and exit of the hanging area. When the hanging part of the base frame enters the hanging area, the limit part restores the deformation, so that the mounting frame with the photovoltaic panel is connected to the base frame through the hanging fastener. When disassembling, it is only necessary to apply a certain pulling force to the mounting frame to force the mounting frame to separate from the base frame, which greatly improves the convenience of disassembly and assembly of the photovoltaic panel and improves the construction efficiency of the overall structure.
[0007] Optionally, the limiting portion is gradually inclined from an end close to the connecting portion to an end away from the connecting portion toward a mounting frame, and the guiding portion is gradually inclined from an end close to the limiting portion to an end away from the limiting portion toward a mounting frame.
[0008] By adopting the above technical solution, the inlet and outlet of the hanging area are reduced, so that the hanging part of the base frame can be buckled in the hanging area.
[0009] Optionally, a connection portion is formed at a connection between the limiting portion and the guiding portion, a surface of the connection portion close to the mounting frame is provided with a protruding block, and a surface of the connection portion away from the mounting frame is provided with a deformation groove.
[0010] By adopting the above technical solution, the setting of the protrusion further reduces the inlet and outlet of the hanging area and improves the hanging stability; the setting of the deformation groove makes it easier for the guide part to deform, so as to facilitate the entry and exit of the hanging part of the base frame.
[0011] Optionally, the base frame is provided with a plurality of hanging rods for hanging with hanging fasteners, the surrounding walls of the hanging rods are provided with limit columns, the connecting portion is provided with a limit groove for the limit column to pass through, one end of the limit groove extends to the limit portion and forms a limit end; the hanging rod is rotatably connected to the base frame, the base frame is provided with a driving assembly, and the driving assembly is used to drive all the hanging rods to rotate synchronously to force the limit column to rotate to the limit end of the limit groove.
[0012] By adopting the above technical solution, a certain thrust is applied to the mounting frame, forcing the hooking rod of the base frame to buckle into the hooking area, and then the driving assembly forces the hooking rod to rotate a certain angle, driving the limit column of the hooking rod to rotate to the limit end of the limit slot, so that the limit part is limited, so that when the outside world pulls the mounting frame, the limit column forms an obstacle to the limit part through the limit end, that is, the mounting frame cannot be detached. When the mounting frame is forced to be disassembled, the limit column must first be rotated out of the limit end of the limit slot before the mounting frame can be detached, thereby improving the connection stability of the mounting frame and improving the anti-theft performance of the mounting frame. In addition, the limit column is inserted into the limit slot, which can play a certain limiting effect on the displacement of the mounting frame and reduce the possibility of displacement of the mounting frame along the axial direction of the hooking rod.
[0013] Optionally, a contact plate is provided on the surface of the limiting portion away from the hanging area, and one end of the contact plate extends to the outside of the limiting end of the limiting groove for contact by the limiting column; when the limiting column pushes the contact plate, the contact plate forces the end of the limiting portion away from the connecting portion to swing toward the surface close to the mounting frame.
[0014] By adopting the above technical solution, when the hook rod forces the limit column to rotate to the limit end of the limit slot, the limit column and the abutment sheet abut each other. If the outside world directly pulls the mounting frame to force the hook rod to move toward the inlet and outlet relative to the connecting portion, the limit column blocks the abutment sheet, so that the hook rod cannot be separated from the hook area, thereby improving the anti-theft performance of the mounting frame (i.e., it is mandatory to rotate the limit column out of the limit end of the limit slot when the mounting frame is disassembled). In addition, if the limit column is located at the limit end of the limit slot, if the mounting frame is directly pulled, the limit column can push the abutment sheet, and the abutment sheet can be pushed to force the end of the limit portion away from the connecting portion to swing toward the surface close to the mounting frame, thereby reducing the inlet and outlet of the hook area, thereby further improving the stability of the connection between the mounting frame and the hook rod.
[0015] Optionally, an abutment groove is formed at one end of the abutment sheet away from the limiting portion, and the abutment groove is arranged in an arc shape for the outer peripheral wall of the limiting column to be embedded.
[0016] By adopting the above-mentioned technical solution, the abutment groove is arranged in an arc shape, which increases the contact area between the limit column and the abutment plate, and when the limit column is embedded in the abutment groove, the limit column can be limited in displacement, thereby reducing the possibility of free sliding of the mounting frame along the axial direction of the hanging rod, and improving the connection stability between the mounting frame and the base frame.
[0017] Optionally, a tightening ring is provided on the surface of the mounting bracket away from the mounting station. The tightening ring has a through-channel for the limiting post to pass through, and the tightening ring and the hanging fastener are arranged at intervals along the length direction of the mounting bracket. When the limiting post of the hanging rod in the hanging area rotates to the limiting end of the limiting groove, the limiting post of the hanging rod close to the tightening ring pulls the tightening ring, and the mounting bracket is tightened through the tightening ring.
[0018] By adopting the above technical solution, a plurality of hanging rods are provided on the base frame. When the mounting bracket is hung on one of the hanging rods through the hanging fastener, at this time, the limiting post of the hanging rod on the base frame close to the tightening ring can pass through the through-channel. When driving the plurality of hanging rods to rotate synchronously and driving the limiting post of the hanging rod in the hanging area to rotate to the limiting end of the limiting groove, at this time, the limiting post of the hanging rod close to the tightening ring rotates synchronously and pulls the tightening ring, so as to tighten the mounting bracket through the tightening ring, further improving the connection stability of the mounting bracket.
[0019] Optionally, a swinging bar is hinged on the surface of the mounting bracket away from the mounting station. A first elastic member is provided between the swinging bar and the mounting bracket. In the normal state, the first elastic member forces the swinging bar to swing to be parallel to the surface of the mounting bracket. The tightening ring is connected with a connecting rod, and one end of the connecting rod away from the tightening ring is hinged to the free end of the swinging bar. A second elastic member is provided between the connecting rod and the swinging bar. In the normal state, the second elastic member forces the through-channel of the tightening ring to face the hanging area.
[0020] By adopting the above technical solution, the setting of the swinging bar provides a connection carrier for the tightening ring, so that the tightening ring is hinged on the surface of the mounting bracket. And through the cooperation of the first elastic member and the second elastic member, the through-channel of the tightening ring can face the hanging area of the mounting bracket in the normal state, that is, the achievable effect is: when the mounting bracket is hung on one of the hanging rods through the hanging fastener, the limiting post of the hanging rod on the base frame close to the tightening ring can pass through the through-channel.
[0021] Optionally, a connecting piece is provided on the side wall of the photovoltaic panel. A first connecting hole is opened on the side wall of the connecting piece. A second connecting hole is opened on the inner wall of the mounting station. The connecting piece is connected with a connecting bolt. The connecting bolt sequentially passes through the first connecting hole and the second connecting hole and is threadedly connected with the second connecting hole. A decorative strip for covering the connecting piece is hinged on the side wall of the mounting bracket. An opening and closing assembly is provided between the decorative strip and the swinging bar. When the tightening ring tightens the mounting bracket, the opening and closing assembly forces the decorative strip to turn over and cover the connecting piece.
[0022] By adopting the above technical solution, when the mounting frame is connected to the base frame through the hanging fastener and the tightening ring, under the action of the opening and closing assembly, the decorative strip can be forced to cover the connecting piece. On the one hand, the connecting bolts on the connecting piece are covered to improve the overall appearance, and on the other hand, the connecting bolts are hidden, further improving the anti-theft performance of the photovoltaic panel.
[0023] Optionally, the opening and closing assembly includes a pull rope and a third elastic member. One end of the pull rope is connected to the tightening ring, and the other end passes through the installation station and is connected to the decorative strip; the third elastic member is arranged at the hinge of the decorative strip and the mounting frame. Under normal conditions, the third elastic member forces the decorative strip to flip so that the connecting piece is exposed.
[0024] By adopting the above technical solution, by driving the rotation of the hanging rod, the tightening ring is driven to tighten the mounting frame. During this process, the tightening ring can pull the decorative strip through the pull rope, thereby forcing the decorative strip to flip to cover the connecting piece, improving the operation convenience of the overall structure.
[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the hanging fastener, when installing the photovoltaic panel, align the hanging fastener of the mounting frame with the hanging part of the base frame, apply a certain thrust to the mounting frame, so that 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 through the guiding part 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 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 to force the mounting frame to be separated from the base frame, greatly improving the disassembly and assembly convenience of the photovoltaic panel and improving the construction efficiency of the overall structure; 2. Through the setting of the limiting column, apply a certain thrust to the mounting frame to force the hanging rod of the base frame to be buckled into the hanging area, and then drive the hanging rod to rotate a certain angle through the driving assembly, driving the limiting column of the hanging rod to rotate to the limiting end of the limiting groove, so as to limit the limiting part. When an external force pulls the mounting frame, the limiting column forms an obstacle to the limiting part through the limiting end, that is, the mounting frame cannot be disassembled. When it is required to disassemble the mounting frame, the limiting column needs to be rotated out of the limiting end of the limiting groove first before the mounting frame can be disassembled, improving the connection stability of the mounting frame and the anti-theft performance of the mounting frame. Moreover, the limiting column is inserted into the limiting groove, which can play a certain limiting effect on the displacement of the mounting frame, reducing the possibility of the mounting frame displacing along the axial direction of the hanging rod; 3. By setting up the tightening ring, multiple hanging rods are arranged on the base frame. After the mounting frame is hung on one of the hanging rods through the hanging fastener, at this time, the limiting posts of the hanging rods on the base frame close to the tightening ring can pass through the threading channels. When driving the multiple hanging rods to rotate synchronously and driving the limiting posts of the hanging rods in the hanging area to rotate to the limiting end of the limiting groove, at this time, the limiting posts of the hanging rods close to the tightening ring rotate synchronously and pull the tightening ring, thereby tightening the mounting frame through the tightening ring and further improving the connection stability of the mounting frame.

Detailed Embodiment
[0028] The following is combined withFigures 1-10 Further detailed description of the present application is provided.
[0029] Embodiment 1: The embodiment of the present application discloses a photovoltaic support frame.
[0030] Referring to Figure 1 、 Figure 2 A photovoltaic support frame includes a mounting frame 1 and a base frame 2. In this embodiment, the mounting frame 1 includes a mounting portion 12 and a bending portion 13. The mounting portion 12 and the bending portion 13 are integrally formed. The mounting portion 12 and the bending portion 13 are bent to form an "L"-shaped mounting frame 1. An installation station 11 is formed between the mounting portion 12 and the bending portion 13. The installation station 11 is used for installing a photovoltaic panel (the photovoltaic panel is not shown in the figure of this embodiment). The photovoltaic panel can be installed on the surface of the mounting portion 12 in the form of bolt connection.
[0031] A plurality of hanging rods 21 are fixedly installed on the base frame 2. A hanging fastener 3 is arranged on one side of the mounting frame 1 away from the installation station 11. The hanging fastener 3 is elastically arranged for hanging the hanging rod 21 of the base frame 2. The hanging fastener 3 includes a connecting portion 31, a limiting portion 32 and a guiding portion 33 which are integrally formed. In this embodiment, one end of the connecting portion 31 is fixedly connected to the side wall of the mounting portion 12 away from the bending portion 13, and the other end is fixedly connected to the limiting portion 32. One end of the limiting portion 32 away from the connecting portion 31 is fixedly connected to the guiding portion 33. A hanging area 34 for buckling the hanging rod 21 is formed between the connecting portion 31, the limiting portion 32 and the surface of the mounting portion 12. The guiding portion 33 and the surface of the mounting frame 1 are spaced apart to form an inlet and outlet 35 of the hanging area 34.
[0032] Referring to Figure 2 The limiting portion 32 is gradually inclined towards the mounting frame 1 from the end close to the connecting portion 31 to the end away from the connecting portion 31. The guiding portion 33 is gradually inclined away from the mounting frame 1 from the end close to the limiting portion 32 to the end away from the limiting portion 32. For the convenience of description, the connection between the limiting portion 32 and the guiding portion 33 is defined as a connecting portion 36. A convex block 361 is fixedly installed on the surface of the connecting portion 36 close to the mounting frame 1. A deformation groove 362 is formed on the surface of the connecting portion 36 away from the mounting frame 1.
[0033] The implementation principle of Embodiment 1 of this application is as follows: Before leaving the factory, the photovoltaic panel can be connected and fixed to the mounting frame 1. When the photovoltaic panel is arranged on-site, the base frame 2 is fixed at the set position, and then the hanging fastener 3 of the mounting frame 1 is aligned with the hanging part of the base frame 2. Apply a certain thrust to the mounting frame 1 to make the hanging part of the base frame 2 enter the inlet and outlet 35 of the hanging area 34. At this time, the hanging part of the base frame 2 can force the limiting part 32 to deform through the guiding part 33 to expand the inlet and outlet 35 of the hanging area 34. After the hanging part of the base frame 2 is buckled into the hanging area 34, the limiting part 32 resumes deformation, so that the mounting frame 1 provided with the photovoltaic panel is connected to the base frame 2 through the hanging fastener 3. When disassembling, only apply a certain pulling force to the mounting frame 1 to force the mounting frame 1 to separate from the base frame 2, which greatly improves the disassembly and assembly convenience of the photovoltaic panel and improves the construction efficiency of the overall structure.
[0034] Embodiment 2: This application embodiment discloses a photovoltaic support frame.
[0035] The difference between the photovoltaic support frame disclosed in this application embodiment and Embodiment 1 is as follows: Refer to Figure 3 , in this embodiment, the mounting frame 1 includes mounting bars 14 and connecting bars 15. The number of mounting bars 14 is set to two. The two ends of the connecting bar 15 are respectively connected to the two mounting bars 14. The connecting bar 15 and the two mounting bars 14 are combined to form a "U"-shaped mounting frame 1; the number of hanging fasteners 3 is set to two, and the two hanging fasteners 3 are arranged corresponding to the two mounting bars 14. The connecting part 31 in each hanging fastener 3 is fixedly installed on the surface of the corresponding mounting bar 14, and the installation station 11 is located on the side of the mounting bar 14 away from the hanging fastener 3.
[0036] Embodiment 3: This application embodiment discloses a photovoltaic support frame.
[0037] The difference between the photovoltaic support frame disclosed in this application embodiment and Embodiment 2 is as follows: Refer to Figure 4 , Figure 5 , in this embodiment, each hanging rod 21 is rotatably connected to the base frame 2 so as to be able to rotate around its own central axis. A limiting column 211 is fixedly installed on the outer peripheral wall of each hanging rod 21. The connecting part 31 of the hanging fastener 3 is provided with a limiting groove 37 for the limiting column 211 to pass through. One end of the limiting groove 37 extends to the limiting part 32. For the convenience of description, the end of the limiting groove 37 close to the limiting part 32 is defined as the limiting end 371 of the limiting groove 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 column 211 to rotate to the limiting end 371 of the limiting groove 37.
[0038] An installation groove 22 is formed in the outer side wall of the base frame 2. The driving assembly 4 includes a driving disk 41, a force applying rod 42 and a synchronizing member. The driving disk 41 is disposed in the installation groove 22. One end of one of the hanging rods 21 extends into the installation groove 22 and is fixedly connected to the driving disk 41 coaxially. A force applying strip 43 is fixedly installed on the outer peripheral wall of the driving disk 41. A sliding groove 431 is formed in the side wall of the force applying strip 43. The length direction of the force applying rod 42 is the same as that of the hanging rod 21. The force applying rod 42 is inserted through the sliding groove 431 so as to be able to slide along the length direction of the hanging rod 21.
[0039] Referring to Figure 5 , a first limiting hole 221 and a second limiting hole 222 are respectively formed in the inner wall of the installation groove 22. Both the first limiting hole 221 and the second limiting hole 222 are 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 column 211 of the hanging rod 21 rotates to one end of the limiting groove 37 close to the connecting portion 31. When the force applying rod 42 is threadedly connected to the second limiting hole 222, the limiting column 211 of the hanging rod 21 rotates to the limiting end 371 of the limiting groove 37. The synchronizing member is arranged as a belt (not shown in the figure). The belt is wound around all the hanging rods 21 at the same time to drive all the hanging rods 21 to rotate synchronously.
[0040] It should be noted that a cover plate (not shown in the figure) is installed at the notch of the installation groove 22. One side of the cover plate is hinged to the inner wall of the installation groove 22. 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 elaborated too much here and is not shown in the figure). With such a design, the cover plate is locked by the anti-theft lock, reducing the risk of unauthorized personnel rotating the driving disk 41 privately.
[0041] In this embodiment, to ensure that when the hanging fastener 3 of the installation frame 1 is buckled to the hanging rod 21, the limiting column 211 can penetrate into the limiting groove 37, a marking scale line (not shown in the figure) can be arranged on the outer peripheral wall of the hanging rod 21. When the limiting column 211 penetrates into the limiting groove 37, the marking scale line is located at the side edge of the installation strip 14. With such a design, the arrangement of the marking scale line is convenient for the installer to observe, so that when the hanging fastener 3 of the installation frame 1 is buckled to the hanging rod 21, the limiting column 211 can penetrate into the limiting groove 37.
[0042] The implementation principle of the third embodiment of the present application is as follows: a certain thrust is applied to the mounting frame 1, forcing the hooking rod 21 of the base frame 2 to buckle into the hooking area 34, and then the hooking rod 21 is driven to rotate a certain angle, driving the limiting column 211 of the hooking rod 21 to rotate to the limiting end 371 of the limiting groove 37, thereby limiting the limiting portion 32, and finally locking the notch of the mounting groove 22 by the cover plate. When an unrelated person outside pulls the mounting frame 1, the limiting column 211 forms an obstacle to the limiting portion 32, that is, the mounting frame 1 cannot be disassembled. When the mounting frame 1 is forced to be disassembled, the limiting column 211 must first be rotated out of the limiting end 371 of the limiting groove 37 before the mounting frame 1 can be disassembled, thereby improving the connection stability of the mounting frame 1 and improving the anti-theft performance of the mounting frame 1. In addition, the limiting column 211 is inserted into the limiting groove 37, which can play a certain limiting effect on the displacement of the mounting frame 1, and reduce the possibility of the mounting frame 1 being displaced along the axial direction of the hooking rod 21.
[0043] Example 4: The embodiment of the present application discloses a photovoltaic support frame.
[0044] The difference between the photovoltaic support frame disclosed in the embodiment of the present application and the embodiment 3 is that: Reference Figure 6 , Figure 7 In this embodiment, a contact piece 38 is fixedly installed on the surface of the limiting portion 32 away from the hanging area 34. The contact piece 38 is installed on the surface of the limiting portion 32 by welding. One end of the contact piece 38 extends to the outside of the limiting end 371 of the limiting groove 37. An abutment groove 381 is provided at the end of the abutment piece 38 away from the limiting portion 32. The abutment groove 381 is arranged in an arc shape for the outer peripheral wall of the limiting column 211 to be embedded and abutted; when the limiting column 211 pushes the contact piece 38, the contact piece 38 forces the end of the limiting portion 32 away from the connecting portion 31 to swing toward the surface close to the mounting frame 1.
[0045] The implementation principle of the fourth embodiment of the present application is as follows: after the hooking rod 21 is buckled into the hooking area 34, the hooking 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 in the abutting groove 381 of the abutting piece 38. On the one hand, the setting of the abutting groove 381 can limit the displacement of the hooking fastener 3, reducing the possibility of the mounting frame 1 sliding freely along the length direction of the hooking rod 21 after being buckled on the hooking rod 21. On the other hand, if an unrelated person outside wants to directly pull the mounting frame 1 to force the hooking rod 21 to leave the hooking area 34, the limiting column 211 can push the abutting piece 38, and the abutting piece 38 can be pushed to force the limiting part 32 to swing away from the end of the connecting part 31 toward the surface close to the mounting frame 1, so as to reduce the inlet and outlet 35 of the hooking area 34, further improve the connection stability between the mounting frame 1 and the hooking rod 21, and thus improve the anti-theft performance of the overall structure.
[0046] Embodiment 5: An embodiment of the present application discloses a photovoltaic support frame.
[0047] The difference between the photovoltaic support frame disclosed in the embodiment of the present application and Embodiment 3 is as follows: Referring to Figure 8 , Figure 9 , in this embodiment, an avoidance groove 141 is formed on the surface of the mounting strip 14 away from the mounting station 11. A swing strip 6 is hinged in the avoidance groove 141. For the convenience of description, the other end of the swing strip 6 is hereinafter defined as the free end of the swing strip 6. A tightening ring 5 is provided at the free end of the swing strip 6. A connecting rod 52 is fixedly connected to the peripheral wall of the tightening ring 5. One end of the connecting rod 52 away from the tightening ring 5 is hinged to the free end of the swing strip 6; the tightening ring 5 is annular and forms a through-channel 51 for the limiting post 211 to pass through. The tightening ring 5 and the hanging fastener 3 are arranged at intervals along the length direction of the mounting strip 14.
[0048] A first elastic member is installed at the hinge between the swing strip 6 and the inner wall of the avoidance groove 141. In the normal state, the first elastic member forces the swing strip 6 to turn into the avoidance groove 141, and the swing strip 6 swings to be parallel to the surface of the mounting frame 1. The first elastic member is set as a first torsion spring (not shown in the figure); a second elastic member is installed at the hinge between the connecting rod 52 and the free end of the swing strip 6. In the normal state, the second elastic member forces the through-channel 51 of the tightening ring 5 to face the hanging area 34. The second elastic member is set as a second torsion spring (not shown in the figure). When the limiting post 211 of the hanging rod 21 in the hanging area 34 rotates to the limiting end 371 of the limiting groove 37, the limiting post 211 of the hanging rod 21 close to the tightening ring 5 pulls the tightening ring 5, and tightens the mounting frame 1 through the tightening ring 5.
[0049] The implementation principle of Embodiment 5 of the present application is as follows: When the mounting frame 1 is hung on one of the hanging rods 21 through the hanging fastener 3, at this time, the limiting post 211 of the hanging rod 21 on the base frame 2 close to the tightening ring 5 can pass through the through-channel 51. When driving the multiple hanging rods 21 to rotate synchronously, driving the limiting post 211 of the hanging rod 21 in the hanging area 34 to rotate to the limiting end 371 of the limiting groove 37, at this time, the limiting post 211 of the hanging rod 21 close to the tightening ring 5 rotates synchronously and pulls the tightening ring 5, so as to tighten the mounting frame 1 through the tightening ring 5, further improving the connection stability between the mounting frame 1 and the base frame 2.
[0050] Embodiment 6: An embodiment of the present application discloses a photovoltaic support frame.
[0051] The difference between the photovoltaic support frame disclosed in the embodiment of the present application and Embodiment 5 is as follows: Referring to Figure 10, in this embodiment, connecting pieces 8 are fixedly installed on two opposite side walls of the photovoltaic panel. A first connecting hole (not shown in the figure) is formed in the side wall of the connecting piece 8, and a second connecting hole (not shown in the figure) is formed in the inner wall of the installation strip 14 at the installation station 11. A connecting bolt 81 is connected to the connecting piece 8. The connecting bolt 81 sequentially passes through the first connecting hole and the second connecting hole and is threadedly connected to the second connecting hole. The photovoltaic panel is detachably installed in the installation station 11 of the mounting rack 1 through the connecting piece 8 and the connecting bolt 81.
[0052] A decorative strip 7 for covering the connecting piece 8 is hinged to the side wall of the installation strip 14 close to the installation station 11. Both ends of the decorative strip 7 extend along the length direction of the installation strip 14; an opening and closing assembly is arranged between the decorative strip 7 and the swinging strip 6. When the tightening ring 5 tightens the mounting rack 1, the opening and closing assembly forces the decorative strip 7 to flip and cover the connecting piece 8.
[0053] Refer to Figure 10 , the opening and closing assembly includes a pulling rope 71 and a third elastic member. One end of the pulling rope 71 is fixedly connected to the tightening ring 5, and the other end passes into the installation station 11 and is fixedly connected to the decorative strip 7. When the tightening ring 5 tightens the mounting rack 1, the pulling rope 71 forces the decorative strip 7 to cover the connecting piece 8 of the photovoltaic panel; the third elastic member is installed at the hinge joint of the decorative strip 7 and the installation strip 14. Under normal conditions (when the tightening ring 5 does not tighten the mounting rack 1), the third elastic member forces the decorative strip 7 to flip so that the connecting piece 8 is exposed. In this embodiment, the third elastic member is set as a third torsion spring (not shown in the figure).
[0054] The implementation principle of Embodiment 6 of this application is as follows: After the mounting rack 1 is buckled to the hanging rod 21 of the base frame 2 through the hanging fastener 3, the hanging rod 21 is driven to rotate so that the tightening ring 5 tightens the mounting rack 1. During the displacement of the tightening ring 5, the decorative strip 7 is pulled through the pulling rope 71, forcing the decorative strip 7 to cover the connecting piece 8 of the photovoltaic panel, improving the overall aesthetics. In addition, the connecting bolt 81 can be hidden, further improving the anti-theft performance of the overall structure.
[0055] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
