A 182×210mm large photovoltaic module structure

Abstract

This utility model relates to the technical field of photovoltaic modules, and in particular to a 182×210mm large photovoltaic module structure, including a mounting frame. The top of the mounting frame has a mounting groove. In this 182×210mm large photovoltaic module structure, when the trapezoidal block moves under the drive of the threaded rod, the inclined surface of the trapezoidal block will squeeze the inclined block, thereby driving the movable rod to overcome the elastic force of the return spring and move towards the limiting groove. When the movable rod moves, one end of it is connected to the through hole of the limiting block to fix the limiting block. Then, the photovoltaic panel is fixed by the pressure block, which facilitates the disassembly and maintenance of the photovoltaic panel. By pulling the handle, the limiting rod is driven to move outward against the elastic force of the compression spring. Then, the two mounting frames are spliced ​​together, and the limiting hole of the connecting block is aligned with the position of the limiting rod. After releasing the handle, the limiting rod is inserted into the limiting hole under the action of the compression spring, thereby splicing and fixing the two mounting frames. The disassembly and assembly are convenient and the practicality is better.

Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic modules, and in particular to a structure of a large photovoltaic module with dimensions of 182×210mm. Background Technology

[0002] A 182×210mm solar cell refers to a photovoltaic cell with dimensions of 182 mm by 210 mm. This type of solar cell is the core component of a photovoltaic module and has the function of generating electricity. In practical applications, in order to protect and enhance the performance of the solar cell, a photovoltaic film is usually added to the top and bottom, then a glass sheet is attached to the top, and a photovoltaic backsheet is added to the bottom. This is called a "photovoltaic module unit". Multiple such photovoltaic module units are combined to form what we usually call a "photovoltaic module", which is also known as a solar panel.

[0003] Patent document CN222073075U discloses a 182×210mm large photovoltaic module structure, including a frame one, in which a solar panel one is installed, and a frame two is provided on the outside of the frame one, which is parallel to the frame one. A solar panel two is installed in the frame two, and a splicing mechanism is installed between the frame one and the frame two. In this utility model, through the cooperation between the drive shaft, the drive gear and the driven gear, the driven shaft can be rotated when the turntable is rotated. Through the cooperation between the bevel gear one and the bevel gear two, the bidirectional lead screw can be rotated. Through the cooperation between the lead screw nut, the slider and the slide groove, the two insert plates can be inserted into the two slots on the opposite sides, and the two mounting blocks can be fixed to the mounting plate. This can fix the frame one and the frame two, thereby facilitating the rapid splicing of the solar panel one and the solar panel two.

[0004] The solution also has the following problems: The solution achieves rapid assembly by assembling and splicing multiple sets of frames. However, the photovoltaic panels are fixedly installed inside the frames. If the photovoltaic panels need to be replaced, the frames need to be disassembled and replaced at the same time. The operation is cumbersome and it is not convenient to directly and quickly replace the photovoltaic panels. This increases the efficiency of maintenance and replacement, so there are certain drawbacks.

[0005] Therefore, in order to solve the above problems, this utility model provides a large photovoltaic module structure of 182×210mm. Utility Model Content

[0006] The purpose of this invention is to provide a 182×210mm large photovoltaic module structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a 182×210mm large photovoltaic module structure, including a mounting frame, a mounting groove on the top of the mounting frame, a photovoltaic panel installed inside the mounting groove, symmetrically spaced limiting grooves at both ends of the two longer edges of the top of the mounting frame, limiting blocks installed inside the limiting grooves, a pressure block installed at one end of the limiting block and on top of the photovoltaic panel, a cavity opened on the two wider outer sides of the mounting frame and between the two limiting grooves, a threaded rod installed between the top and bottom of the inner side of the cavity, a trapezoidal block installed on the outer ring surface of the threaded rod, symmetrically spaced return springs on the two inner side walls of the cavity, a movable rod installed inside the return spring, and a wedge installed at one end of the movable rod and near the trapezoidal block.

[0008] Preferably, a handle is installed at the top end of the threaded rod after it extends through the top of the mounting frame. The outer ring surface of the threaded rod is threadedly connected to the interior of the trapezoidal block, and the two outer sides of the trapezoidal block are in contact with the inner sidewall of the cavity.

[0009] Preferably, the end of the movable rod away from the inclined block passes through the return spring and extends into the interior of the limiting groove, and the two outer sides of the inclined block are in contact with the inner sidewall of the cavity.

[0010] Preferably, a through hole is provided on the outer side of the limiting block, and the movable rod can extend into the through hole after the limiting block is fully inserted into the limiting groove.

[0011] Preferably, fixing ears are symmetrically installed at both ends of the narrower side of the mounting frame, and a connecting block is installed at the end of the mounting frame away from the two fixing ears. Limiting holes are symmetrically opened at both ends of the connecting block, so that the outside of the connecting block fits tightly with the outside of the two fixing ears when the two mounting frames are spliced.

[0012] Preferably, a limiting rod is installed between the inner sidewalls of the fixing ear, a compression spring is installed on the outer ring surface of the limiting rod, a limiting plate is installed on the outside of the limiting rod and in close contact with the compression spring, one end of the limiting rod extends to the outside of the fixing ear and is fitted with a handle, and the end of the limiting rod away from the handle extends to the outside of the fixing ear and is connected to the inside of the limiting hole.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] This 182×210mm large photovoltaic module structure features a trapezoidal block that moves under the influence of a threaded rod. The inclined surface of the trapezoidal block presses against the inclined block, causing the movable rod to overcome the spring force of the return spring and move towards the limiting groove. One end of the movable rod engages with the through hole of the limiting block, thus fixing the limiting block in the limiting groove. The pressure block then secures the photovoltaic panel, ensuring its stability on the mounting frame and facilitating disassembly and maintenance. Pulling the handle moves the limiting rod outwards against the spring force of the compression spring. The two mounting frames are then joined together, aligning the limiting hole of the connecting block with the limiting rod. Releasing the handle allows the limiting rod to insert into the limiting hole under the spring force of the compression spring. Simultaneously, the limiting plate prevents excessive movement of the limiting rod, thus securing the two mounting frames together. This design offers convenient assembly and disassembly, enhancing practicality. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 - Figure 4 The present invention will be described in further detail below.

[0021] A 182×210mm large photovoltaic module structure, referring to Figure 1 - Figure 4The system includes a mounting frame 1, with a mounting groove 101 at the top. A photovoltaic panel 2 is installed inside the mounting groove 101. Limiting grooves 102 are symmetrically opened at both ends of the two longer edges of the top of the mounting frame 1. Limiting blocks 3 are installed inside the limiting grooves 102. A pressure block 4 is installed at one end of the limiting block 3 and at the top of the photovoltaic panel 2. A cavity 103 is opened on the two wider sides of the outer side of the mounting frame 1 and between the two limiting grooves 102. A threaded rod 5 is installed between the top and bottom of the inner side of the cavity 103. A trapezoidal block 6 is installed on the outer ring surface of the threaded rod 5. Reset springs 7 are symmetrically installed on the two inner walls of the cavity 103. A movable rod 8 is installed inside the reset spring 7. A wedge 9 is installed at one end of the movable rod 8 and the end near the trapezoidal block 6.

[0022] Reference Figure 3 - Figure 4 The top end of the threaded rod 5 extends through the top of the mounting frame 1 and is fitted with a handle 10. The outer ring surface of the threaded rod 5 is threadedly connected to the inside of the trapezoidal block 6. The two outer sides of the trapezoidal block 6 are in contact with the inner sidewall of the cavity 103. By rotating the handle 10, the threaded rod 5 is driven to rotate. Since the threaded rod 5 and the trapezoidal block 6 are threadedly connected and the two sides of the trapezoidal block 6 are in contact with the inner sidewall of the cavity 103, the rotation of the threaded rod 5 will cause the trapezoidal block 6 to move along the axial direction of the threaded rod 5.

[0023] Reference Figure 3 - Figure 4 The end of the movable rod 8 away from the inclined block 9 passes through the return spring 7 and extends into the limiting groove 102. The two outer sides of the inclined block 9 are in contact with the inner wall of the cavity 103. When the trapezoidal block 6 moves under the drive of the threaded rod 5, the inclined surface of the trapezoidal block 6 will press against the inclined block 9. Since the two sides of the inclined block 9 are in contact with the inner wall of the cavity 103, the inclined block 9 will move along the inner wall of the cavity 103, thereby driving the movable rod 8 to overcome the elastic force of the return spring 7 and move towards the limiting groove 102. The movable limit block 3 has a through hole 301 on its outer side. After the limit block 3 is fully inserted into the limit groove 102, the movable rod 8 can extend into the through hole 301. When the movable rod 8 moves, one end of it is inserted into the through hole 301 of the limit block 3 to fix the limit block 3, thereby fixing the limit block 3 in the limit groove 102. Then, the photovoltaic panel 2 is fixed by the pressure block 4 to ensure the stability of the photovoltaic panel 2 on the mounting frame 1 and facilitate the disassembly and maintenance of the photovoltaic panel 2.

[0024] Reference Figure 1 - Figure 2The mounting frame 1 has symmetrically installed fixing ears 11 on both ends of the narrower side. A connecting block 16 is installed on the outer end of the mounting frame 1 away from the two fixing ears 11. Limiting holes 1601 are symmetrically opened on both ends of the outer side of the connecting block 16. When the two mounting frames 1 are spliced, the outer side of the connecting block 16 is tightly fitted with the outer side of the two fixing ears 11. When it is necessary to splice the two mounting frames 1, the connecting block 16 of one mounting frame 1 is tightly fitted with the two fixing ears 11 of the other mounting frame 1 to facilitate subsequent splicing and fixing.

[0025] Reference Figure 1 - Figure 2 A limiting rod 12 is installed between the inner walls of the fixing ear 11. A compression spring 13 is installed on the outer ring surface of the limiting rod 12. A limiting plate 14 is installed on the outside of the limiting rod 12 and close to the compression spring 13. One end of the limiting rod 12 extends to the outside of the fixing ear 11 and is fitted with a handle 15. The other end of the limiting rod 12, away from the handle 15, extends to the outside of the fixing ear 11 and is inserted into the inside of the limiting hole 1601. By pulling the handle 15, the limiting rod 12 is moved outward against the elastic force of the compression spring 13. Then, the two mounting frames 1 are spliced ​​together so that the limiting hole 1601 of the connecting block 16 corresponds to the position of the limiting rod 12. After releasing the handle 15, the limiting rod 12 is inserted into the limiting hole 1601 under the elastic force of the compression spring 13. At the same time, the limiting plate 14 plays a limiting role to prevent the limiting rod 12 from moving excessively, thereby splicing and fixing the two mounting frames 1, which is convenient for assembly and disassembly.

[0026] The implementation principle of a 182×210mm large photovoltaic module structure according to this utility model embodiment is as follows: When using the module, rotating the throttle 10 drives the threaded rod 5 to rotate. Since the threaded rod 5 is threadedly connected to the trapezoidal block 6 and the two sides of the trapezoidal block 6 are in contact with the inner wall of the cavity 103, the rotation of the threaded rod 5 will cause the trapezoidal block 6 to move along the axial direction of the threaded rod 5. When the trapezoidal block 6 moves under the drive of the threaded rod 5, the inclined surface of the trapezoidal block 6 will press against the inclined block 9. Since the two sides of the inclined block 9 are in contact with the inner wall of the cavity 103, the inclined block 9 will move along the inner wall of the cavity 103, thereby driving the movable rod 8 to overcome the elastic force of the return spring 7 and move towards the limiting groove 102. When the movable rod 8 moves, one end of it is connected to the through hole 301 of the limiting block 3. The limiting block 3 is fixed in the limiting groove 102, and then the photovoltaic panel 2 is fixed by the pressure block 4 to ensure the stability of the photovoltaic panel 2 on the mounting frame 1, which facilitates the disassembly and maintenance of the photovoltaic panel 2. By pulling the handle 15, the limiting rod 12 is moved outward against the elastic force of the compression spring 13. Then the two mounting frames 1 are spliced ​​together, and the limiting hole 1601 of the connecting block 16 is aligned with the position of the limiting rod 12. After releasing the handle 15, the limiting rod 12 is inserted into the limiting hole 1601 under the elastic force of the compression spring 13. At the same time, the limiting plate 14 plays a limiting role to prevent the limiting rod 12 from moving excessively, thereby splicing and fixing the two mounting frames 1. The disassembly and assembly are convenient and the practicality is better. The external helix opening angle of the threaded rod 5 is 20 degrees, and the thread self-locking condition is calculated by the following formula: self-locking condition = friction coefficient * tan (helix angle) ≥ 1.
