Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic technology, and more specifically, to a plug structure and an adjustable fixed photovoltaic bracket. Background Art
[0002] Photovoltaic power generation is a green energy technology that converts solar radiation into direct current. With the improvement of environmental awareness and the transformation of the energy structure, photovoltaic power generation has been more and more widely used globally and has become an important renewable energy source. A photovoltaic system is a commonly used device for photovoltaic power generation, and among them, a photovoltaic bracket is an important part of the photovoltaic system. The photovoltaic modules (i.e., the power generation part) of the photovoltaic system are supported by the photovoltaic bracket.
[0003] Currently, common photovoltaic systems include a tracking system and a fixed adjustable bracket system. In the fixed adjustable bracket system, since the inclination angle of the bracket needs to be adjusted periodically, its stability after adjustment is crucial. And after adjusting the inclination angle, it is often necessary to use a locking structure to ensure the stability of the bracket in the fixed state. The quality of the locking structure determines the stability and installation efficiency of the adjustable bracket system. Currently, common locking structures generally rely on bolts for locking. When the bracket is adjusted to the corresponding angle, insert the bolt and tighten the nut to achieve the purpose of locking. When the angle needs to be adjusted, loosen the nut and pull out the bolt. This locking structure has some problems. 1. When adjusting, the efficiency is too slow. 2. The bolt may have an adhesion phenomenon. If this situation occurs, it will cause the adjustable bracket to lose the function of adjusting the angle. Summary of the Utility Model

Figure 5 Fig. is a structural schematic diagram of the plug 140 in the plug structure 100 provided in this embodiment. Figure 6 Fig. is a structural schematic diagram of the cover plate 120 in the plug structure 100 provided in this embodiment. Please refer to Figures 1-6 In this embodiment, a plug structure 100 is provided, and at the same time, an adjustable fixed photovoltaic bracket 10 is provided. The adjustable fixed photovoltaic bracket 10 includes the above-mentioned plug structure 100.
[0041] In this embodiment, the adjustable fixed photovoltaic bracket 10 includes a main beam, a column 21, and a plug structure 100. The column 21 is used to rotatably support the main beam, and the plug structure 100 is installed on the column 21. A rod member 25 is also installed on the main beam. One end of the rod member 25 is movably arranged at the plug structure 100. The plug structure 100 locks the movement of the rod member 25 relative to the column 21 to lock the rotation of the main beam relative to the column 21.
[0042] Optionally, the adjustable fixed photovoltaic bracket 10 further includes a bearing arc rotation structure 22. The bearing arc rotation structure 22 is arranged between the column 21 and the main beam, so that the main beam can rotate relative to the column 21. Specifically, the bearing arc rotation structure 22 includes a first rotation part 23 and a second rotation part 24 that are rotatably connected to each other. The first rotation part 23 is fixedly connected to the column 21, and the second rotation part 24 is fixedly connected to the main beam. It should be noted that in this embodiment, the main beam is a tubular member with a square cross-section. Figure 1 The structure of the main beam is not shown in Figure 1As shown, the second rotating part 24 has a square through-hole 27 for installing and fixing the main beam. One end of the rod 25 is rotatably installed on the second rotating part 24, and an indirect connection with the main beam is achieved through the second rotating part 24. It can be understood that in some other embodiments, the structure can also be set to directly connect the rod 25 to the main beam. When the angle of the main beam needs to be adjusted, the pin structure 100 is in the unlocked state at this time. During the change of the angle of the main beam, the rod 25 rotates relative to the second rotating part 24, and at the same time, the rod 25 moves in the space 150 of the pin structure 100; when the pin structure 100 is in the locked state, the movement of the rod 25 relative to the column 21 is locked.
[0043] The pin structure 100 includes a base 110, a cover plate 120, and a pin 140. The base 110 is used for fixedly connecting to the column 21. The cover plate 120 is installed on the base 110, and a space 150 for the rod 25 to move is formed between the cover plate 120 and the base 110. A first insertion hole 114 is provided on the base 110, and a second insertion hole 121 is provided on the cover plate 120. The first insertion hole 114 and the second insertion hole 121 are located on both sides of the space 150. The pin 140 includes a rod portion and a convex block 143 protruding from the rod portion. When the pin 140 is inserted into the first insertion hole 114 and the second insertion hole 121, a part of the rod portion penetrates through the space 150, so as to be inserted into the rod 25 in the space 150, thereby locking the movement of the rod 25 relative to the column 21, and further locking the relative rotation between the main beam and the column 21; when the pin 140 is not inserted into the first insertion hole 114 and the second insertion hole 121, the movement of the rod 25 relative to the column 21 is unlocked at this time, and further the relative rotation between the main beam and the column 21 is unlocked, so that the angle of the main beam is adjustable, and the adjustment is more convenient and fast. At the same time, since the pin 140 is used to replace the bolt in the prior art, the problem that the main beam cannot be adjusted in angle due to the adhesion of the bolt is avoided. Moreover, the second insertion hole 121 has a notch 123 for the convex block 143 to enter and exit the space 150. When the pin 140 is in the locked state, the convex block 143 can enter the space 150 through the notch 123 and rotate to an angle misaligned with the notch 123. In this way, the movement of the rod 25 relative to the cover plate 120 is limited, thereby blocking the movement of the pin 140 in the direction of disengaging from the second insertion hole 121, and ensuring the stability when the pin 140 is in the locked state.
[0044] Specifically, a third insertion hole 26 is provided on the rod 25, and the pin 140 is inserted into the first insertion hole 114, the second insertion hole 121, and the third insertion hole 26 at the same time to lock the rod 25.
[0045] The following further explains the pin structure 100 provided in this embodiment:
[0046] Figure 7Schematic diagram of the base 110 in the plug structure 100 provided in this embodiment. Please refer to Figures 1-7 , in this embodiment, the base 110 includes a first connecting arm 111, a connecting plate portion 112, and a second connecting arm 113 that are connected in sequence. The first connecting arm 111 and the second connecting arm 113 are fixedly connected to both sides of the column 21, so that the base 110 is fixedly connected to the column 21, and the first insertion hole 114 is provided at the connecting plate portion 112. Specifically, the base 110 is a U-shaped member, and its two free arms are respectively used as the first connecting arm 111 and the second connecting arm 113 to be fixedly connected to the column 21. The first insertion hole 114 is provided at the connecting plate portion 112, and the first insertion hole 114 is coaxially arranged with the second insertion hole 121. In this way, the rod portion inserted into the second insertion hole 121 and coaxially arranged with the second insertion hole 121 can be inserted into the first insertion hole 114.
[0047] In this embodiment, the cover plate 120 is a rectangular plate-like member, and a second insertion hole 121 is provided thereon. The second insertion hole 121 includes a circular hole portion 122 and a notch 123 communicating with the circular hole portion 122. The size of the circular hole portion 122 is adapted to the size of the rod member 25 of the plug 140, ensuring that the rod member 25 can be inserted into the circular hole portion 122. The size of the notch 123 is adapted to the size of the convex block 143, ensuring that the convex block 143 can enter and exit the space 150 through the notch 123. As Figure 3 and Figure 4 shown, when the plug 140 is in the locked state, the convex block 143 is located in the space 150.
[0048] Furthermore, a first fixing hole 115 is further provided on the connecting plate portion 112, a second fixing hole 124 is further provided on the cover plate 120, and the plug structure 100 further includes a fixing bolt 131 and a bolt sleeve 132. The bolt sleeve 132 is sleeved outside the fixing bolt 131 and is located between the connecting plate portion 112 and the cover plate 120, so as to maintain the spacing distance between the connecting plate portion 112 and the cover plate 120 through the bolt sleeve 132, that is, to form a stable space 150. The fixing bolt 131 is installed at the first fixing hole 115 and the second fixing hole 124 to lock the connecting plate portion 112 and the cover plate 120.
[0049] Specifically, the bolt sleeve 132 is a circular tube, and its outer diameter is larger than the first fixing hole 115 and the second fixing hole 124. By arranging the bolt sleeve 132 between the connecting plate portion 112 and the cover plate 120, and by passing the fixing bolt 131 through the first fixing hole 115, the bolt sleeve 132, and the second fixing hole 124 in sequence, and fastening the connecting plate portion 112, the bolt sleeve 132, and the cover plate 120 into one body, so that while the connecting plate portion 112 and the cover plate 120 are fixed, a space 150 for the rod member 25 to move can be formed.
[0050] Optionally, in this embodiment, the number of the first fixing holes 115 and the second fixing holes 124 is two each. The two first fixing holes 115 are arranged on both sides of the first insertion hole 114, and the two second fixing holes 124 are arranged on both sides of the second insertion hole 121. Correspondingly, in this embodiment, the number of the bolt sleeves 132 and the fixing bolts 131 is correspondingly set to two. It can be understood that the number of the first fixing holes 115 and the second fixing holes 124 is not limited here. In some other embodiments, the number of the first fixing holes 115 and the second fixing holes 124 can also be specifically set according to requirements. For example, the number of the first fixing holes 115 is set to four, and two first fixing holes 115 are arranged on each side of the first insertion hole 114. Correspondingly, the number of the second fixing holes 124, the bolt sleeves 132 and the fixing bolts 131 is also set to four.
[0051] It should be noted that the connection structure between the cover plate 120 and the base 110 is not limited here. It can be understood that in some other embodiments, other connection methods can also be adopted. For example, the cover plate 120 is set as a U-shaped part or a "ji"-shaped part, so that a space 150 for the rod member 25 to move can be formed after the cover plate 120 is connected to the base 110.
[0052] Furthermore, the cover plate 120 is inclined relative to the connecting plate portion 112, so that the opening of the space 150 formed between the cover plate 120 and the connecting plate portion 112 is inclined relative to the vertical direction. In this way, it is convenient for the obliquely arranged rod member 25 to be inserted into the space 150 from the opening and move in the space 150. Specifically, in this embodiment, the connection line of the two first fixing holes 115 is inclined relative to the horizontal direction.
[0053] Please refer to Figures 1-5 , in this embodiment, the rod portion includes a first rod segment 141 and a second rod segment 142, and the first rod segment 141 and the second rod segment 142 are connected to each other to form an L shape. The convex block 143 is arranged on the first rod segment 141, and the first rod segment 141 is used for being inserted into the first insertion hole 114 and the second insertion hole 121, so that the bolt 140 is in a locked state (as Figures 2-4 shown). When the bolt 140 is in the locked state, the second rod segment 142 is located on the side of the cover plate 120 away from the base 110. In other words, in this embodiment, the first rod segment 141 can be regarded as a functional part for playing the role of insertion and locking, and the second rod segment 142 can be regarded as a manipulation part for the staff to operate.
[0054] Further, the protruding direction of the bump 143 and the extending direction of the second rod segment 142 are misaligned in the circumferential direction of the first rod segment 141. Optionally, in this embodiment, the protruding direction of the bump 143 and the extending direction of the second rod segment 142 are misaligned by 90° in the circumferential direction of the first rod segment 141. In this way, when it is necessary to manipulate the bolt 140 to insert into or pull out from the second insertion hole 121 and when it is necessary to align the bump 143 with the notch 123, the second rod segment 142 will not block the alignment state of the bump 143 and the notch 123, facilitating observation and operation.
[0055] Further, the end of the first rod segment 141 away from the second rod segment 142 is conical, facilitating the insertion of the first rod segment 141 into the first insertion hole 114 and the second insertion hole 121.
[0056] In this embodiment, the bump 143 is trapezoidal, and one end of the trapezoid has a tapered head 144, and the tapered head 144 is located at the end of the bump 143 close to the cover plate 120. At the same time, the trapezoid also includes a long side 145 and a short side 146 located on both sides of the tapered head. The long side 145 and the short side 146 are respectively located at different circumferential positions of the rod portion.
[0057] Specifically, the bump 143 is a right trapezoid, and it also has a flat head 147 located at the other end of the bump 143 opposite to the tapered head 144. The tapered head 144 is located at the end of the bump 143 close to the second rod segment 142, and the flat head 147 is located at the end of the bump 143 close to the conical end of the first rod segment 141. The long side 145 and the short side 146 are the lateral positions where the two parallel sides of the trapezoid are located. The long side 145 and the short side 146 are located at different circumferential positions of the rod portion. In this way, after the first rod segment 141 of the bolt 140 is inserted into the second insertion hole 121, the bump 143 enters the space 150 between the cover plate 120 and the base 110 from the notch 123. At this time, the bump 143 is still in a position facing the notch 123. Subsequently, rotate the bolt 140 in the direction from the long side 145 to the short side 146, so that the bump 143 rotates to a position misaligned with the notch 123. Moreover, as the bolt 140 is rotated, the long side 145 is rotated to the inside of the cover plate 120 to abut against the cover plate 120, further ensuring the effect of top locking and locking.
[0058] The latch structure 100 and the adjustable fixed photovoltaic bracket provided by the embodiment of the utility model are used. After the angle of the main beam is adjusted to the desired position, a third plug hole 26 on the rod 25 is aligned with the first plug hole 114 and the second plug hole 121. At this time, the latch 140 is inserted into the second plug hole 121, and the protrusion 143 is aligned with the notch 123, so that the protrusion 143 enters the space 150 between the cover plate 120 and the base 110 through the notch 123. The latch 140 is inserted into the first plug hole 114 at the same time. When the rod 25 is locked by the second plug hole 121 and the third plug hole 26, the protrusion 143 is located between the rod 25 and the cover plate 120. At this time, the latch 140 is rotated to make the protrusion 143 misaligned with the notch 123, so as to achieve the locking effect and ensure the stability after adjustment. When the angle of the main beam needs to be adjusted and the latch 140 needs to unlock the activities of the rod 25 and the column 21, the latch 140 is rotated to rotate the protrusion 143 to a position opposite to the notch 123. At this time, the latch 140 can be pulled out to achieve unlocking. By adopting the latch structure 100 to achieve the locking of the adjustable fixed photovoltaic bracket, the operation is more convenient and quick. In addition, since the protrusion 143 is set on the latch 140, the locking effect after plugging and locking can be achieved through the protrusion 143, which further ensures the stability of the bracket after adjustment and helps to reduce the maintenance cost and failure rate during use.
[0059] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technology in this field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
