Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component installation, in particular to an installation pressing block structure and a photovoltaic system. Background Art

[0002] At present, for new users of industrial and commercial distributed photovoltaic projects, integrated metal roofs are very suitable. That is, special-shaped structures are directly made on the metal roof, and then used for the installation of solar cell modules. Compared with the traditional roof + bracket + module form, this installation method saves the bracket. Although the cost of the metal roof is slightly increased, the overall cost is greatly reduced. In addition, the integrated structure also eliminates the leakage problem that may be caused by the traditional bracket drilling method.

[0003] Specifically, after the metal roof is laid, a metal pressure block will be used when installing the components. The current conventional practice is a bolt, a pressure block and a bottom support plate, wherein a thread that cooperates with the bolt is provided on the bottom support plate. During on-site operations, it is necessary to first pass the bolt through the hole in the middle of the pressure block, and then assemble it with the bottom support plate. The sizes of the several components are adjusted to each other, and then adjusted to the appropriate angles. The bottom support plate is placed in the roof groove, and then the bolts are tightened with electric tools. The bottom support plate moves upward and cooperates with the pressure block to clamp and fix the component. With a metal pressure block of this structure, if a problem is found after tightening the bolts, it needs to be readjusted. Since the special-shaped bottom support plate has been clamped and deformed with the sheet metal, the retraction bolt cannot loosen the bottom support plate, and other tools need to be used for removal, which is relatively inefficient. Utility Model Content

[0004] Based on this, it is necessary to provide a mounting block structure and a photovoltaic system to address the technical problem in the prior art that the bottom support piece of the metal block is easily deformed, resulting in low removal efficiency.

[0005] A mounting block structure, comprising a block and a connecting assembly, wherein the block is used to be connected to a frame of a photovoltaic assembly; the connecting assembly comprises:

[0006] A bottom support sheet is used to be arranged in the roof groove of the metal tile, and the bottom support sheet is configured with a connection hole and a receiving groove connected to the connection hole;

[0007] A connecting piece, passing through the mounting hole on the pressing block and cooperating with the connecting hole on the bottom support sheet, so as to fasten the pressing block and the metal tile;

[0008] A guide sleeve, which is sleeved outside the connecting member, and one end of the guide sleeve is accommodated in the accommodating groove;

[0009] The guide sleeve cooperates with the groove wall of the accommodating groove along the axis of the guide sleeve so that the guide sleeve can move relative to the bottom support plate along its axis and limit the circumferential rotation between the guide sleeve and the bottom support plate along the guide sleeve.

[0010] In one embodiment, the bottom support sheet includes:

[0011] A connecting portion, configured with the connecting hole;

[0012] A bottom support plate, wherein the connecting hole extends to a side of the bottom support plate away from the connecting portion;

[0013] The accommodating portion is arranged on a side of the bottom support plate away from the connecting portion, and the accommodating portion is configured with the accommodating groove, which is coaxially arranged with the connecting portion.

[0014] In one of the embodiments, one of the outer circumferential surface of the guide sleeve and the groove wall of the accommodating groove is provided with a guide groove, and the other is provided with a guide protrusion, the guide groove cooperates with the guide protrusion, and the extension direction of the guide groove and the guide protrusion is along the axial direction of the guide sleeve.

[0015] In one of the embodiments, at least two guide protrusions are provided on the groove wall of the accommodating groove, and at least two guide grooves matching with the guide protrusions are provided on the outer peripheral surface of the guide sleeve. After the guide protrusions match with the guide grooves, the top surface of the bottom support plate and the lower surface of the roof groove interact in the longitudinal direction.

[0016] In one embodiment, the guide groove is configured to penetrate through the sleeve wall of the guide sleeve.

[0017] In one of the embodiments, a depth of the guide groove along the axial direction of the guide sleeve is greater than a height of the guide protrusion along the axial direction of the accommodating groove.

[0018] In one of the embodiments, the inner diameter of the receiving groove is larger than the inner diameter of the connecting hole, so that the receiving groove defines a limiting step on one side of the bottom support plate to limit the movement of the guide sleeve.

[0019] In one embodiment, the connecting hole is a threaded hole, and one end of the connecting piece is provided with an external thread to match with the threaded hole.

[0020] In one embodiment, a limiting plate is constructed at one end of the guide sleeve away from the bottom support plate, and the limiting plate is used to be set in the limiting groove of the pressure block. The limiting plate and the groove wall of the limiting groove resist each other to limit the relative rotation of the guide sleeve and the pressure block.

[0021] A photovoltaic system comprises the mounting block structure as described above.

[0022] Beneficial effects of the utility model:

[0023] The utility model provides a mounting block structure, which connects the block to the frame of the photovoltaic module and fastens the block to the metal tile through a connecting assembly, thereby realizing a fixed connection between the photovoltaic module and the metal tile. Specifically, the bottom support sheet is arranged in the roof groove of the metal tile, the guide sleeve is arranged in the receiving area on the bottom support sheet, and the connecting piece passes through the mounting hole on the block and cooperates with the connecting hole on the bottom support sheet to fix the block to the metal tile, thereby realizing the mutual connection between the photovoltaic module and the metal tile. In the present invention, the guide sleeve and the groove wall of the accommodating groove are guided and cooperated along the axial direction of the guide sleeve, so that the guide sleeve can only move along the axial direction of the guide sleeve, and cannot rotate relative to the bottom support plate, thereby limiting the rotation of the bottom support plate relative to the metal tile, and ensuring that the bottom support plate can only move along the axis of the guide sleeve at a fixed angle, so that the contact surface between the bottom support plate and the metal tile is fixed, and the relative displacement of the contact surface of the metal tile will not be caused by the tightening of the connecting piece, thereby avoiding wear. At the same time, the two ends of the bottom support plate will not contact the groove walls on both sides of the roof groove, thereby avoiding mutual extrusion damage. After the locking force applied by the connecting piece disappears, the module composed of the connecting piece and the bottom support plate sinks as a whole, and the bottom support plate is out of contact with the metal tile. Compared with the prior art, no additional operation is required, and the construction is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Referring to FIGS. 1 to 8 , an embodiment of the present invention provides a mounting block structure 100, which includes a block 110 and a connection assembly 120. The block 110 is used to connect to the frame of the photovoltaic module; the connection assembly 120 includes a bottom support sheet 121, a connection member 122 and a guide sleeve 123. The bottom support sheet 121 is used to be arranged in the roof groove 210 of the metal tile 200. The bottom support sheet 121 is configured with a connection hole 1211a and a receiving groove 1213a connected to the connection hole 1211a; the connection member 122 passes through the block The mounting hole 112 on 110 cooperates with the connecting hole 1211a on the bottom support piece 121 to fasten the pressing block 110 and the metal tile 200; the guide sleeve 123 is sleeved on the outside of the connecting piece 122, and one end of the guide sleeve 123 is accommodated in the accommodating groove 1213a; wherein, the guide sleeve 123 cooperates with the groove wall of the accommodating groove 1213a along the axis of the guide sleeve 123, so that the guide sleeve 123 can move relative to the bottom support piece 121 along its axis direction, and limit the circumferential rotation between the guide sleeve 123 and the bottom support piece 121 along the guide sleeve.

[0041] The utility model provides a mounting block structure 100, which connects the block 110 to the frame of the photovoltaic module, and fastens the block 110 to the metal tile 200 through the connecting assembly 120, thereby realizing the fixed connection between the photovoltaic module and the metal tile 200. Specifically, the bottom support sheet 121 is arranged in the roof groove 210 of the metal tile 200, the guide sleeve 123 is arranged in the receiving groove 1213a on the bottom support sheet 121, and the connecting member 122 passes through the mounting hole 112 on the block 110 and cooperates with the connecting hole 1211a on the bottom support sheet 121, so as to fix the block 110 and the metal tile 200 together, thereby realizing the mutual connection between the photovoltaic module and the metal tile 200. In the present invention, the guide sleeve 123 and the groove wall of the accommodating groove 1213a are guided and matched along the axial direction of the guide sleeve 123, so that the guide sleeve 123 can only move along the axial direction of the guide sleeve 123, and cannot rotate relative to the bottom support piece 121, thereby limiting the rotation of the bottom support piece 121 relative to the metal tile 200, so as to ensure that the bottom support piece 121 moves along the axis of the guide sleeve 123 at a fixed angle, so that the contact surface between the bottom support piece 121 and the metal tile 200 is fixed, and the relative displacement of the contact surface of the metal tile 200 will not be caused by the tightening of the connecting piece 122, thereby avoiding wear. At the same time, the two ends of the bottom support piece 121 will not contact the groove walls on both sides of the roof groove 210, thereby avoiding mutual extrusion damage. After the locking force applied by the connecting piece 122 disappears, the module composed of the connecting piece 122 and the bottom support piece 121 sinks as a whole, and the bottom support piece 121 is out of contact with the metal tile 200. Compared with the prior art, no additional operation is required, and the construction is convenient. Specifically, the connection hole 1211a of the roof trough 210 is a threaded hole, and one end of the connection piece 122 is provided with an external thread to match the threaded hole. By setting the connection hole 1211a as a threaded hole and providing an external thread at one end of the connection piece 122, the connection piece 122 is threadedly matched with the threaded hole on the bottom support sheet 121 to apply a longitudinal pre-tightening force between the metal tile 200 and the pressing block 110, thereby achieving mutual fixation of the metal tile 200 and the pressing block 110.

[0042] As shown in Fig. 3, Fig. 4 and Fig. 5, in one embodiment, the bottom support sheet 121 includes a connecting portion 1211, a bottom support plate 1212 and a receiving portion 1213 which are connected in sequence, the connecting portion 1211 is configured with a connecting hole 1211a; the connecting hole 1211a penetrates the bottom support plate 1212; the receiving portion 1213 is arranged on the side of the bottom support plate 1212 away from the connecting portion 1211, the receiving portion 1213 is configured with a receiving groove 1213a, and the receiving groove 1213a is arranged coaxially with the connecting portion 1211. By arranging the connecting portion 1211 and the receiving portion 1213 on both sides of the bottom support plate 1212, the receiving portion 1213 for accommodating the guide sleeve and the connecting portion for connecting with the connecting member are integrated on the bottom support plate 1212, so as to reduce the number of parts, improve the integration of the bottom support sheet 1212, and thus improve the installation efficiency. Specifically, the bottom support plate 1212 is configured as a substantially rectangular plate-shaped structure, which is advantageous in preventing the bottom support sheet 121 from being separated from the metal tile 200 , thereby ensuring the reliability of the connection between the bottom support sheet 121 and the metal tile 200 .

[0043] It should be noted that, in this embodiment, the length of the bottom support plate 1212 should be slightly wider than the groove width of the roof groove 210. This arrangement allows, in the initial stage of installation, when the guide groove 1231 on the guide sleeve 123 and the guide protrusion 1213b on the accommodating groove 1213a of the bottom support piece 121 have not yet matched, the rotation of the bottom support piece 121 can be limited by the mutual resistance between the bottom support plate 1212 and the side groove wall of the roof groove 210, so that when the connecting piece 122 is twisted, a tangential force can be generated between the connecting piece 122 and the side wall of the connecting hole 1211a, thereby ensuring that the connecting piece 122 moves relative to the bottom support piece 121 along its axial direction.

[0044] In one embodiment, one of the outer circumferential surface of the guide sleeve 123 and the groove wall of the receiving groove 1213a is provided with a guide groove 1231, and the other is provided with a guide protrusion 1213b, the guide groove 1231 and the guide protrusion 1213b are guided and matched, and the extension direction of the guide groove 1231 and the guide protrusion 1213b is along the axial direction of the guide sleeve 123. By providing the guide groove 1231 on one of the outer circumferential surface of the guide sleeve 123 and the groove wall of the receiving groove 1213a, and providing the guide protrusion 1213b on the other, the guiding cooperation between the guide sleeve 123 and the bottom support sheet 121 is achieved, thereby limiting the bottom support sheet 121 from rotating relative to the guide sleeve 123.

[0045] As shown in FIG. 5 and FIG. 7 , in one embodiment, at least two guide protrusions 1213b are arranged on the groove wall of the receiving groove 1213a, and the guide protrusions 1213b protrude from the groove wall of the receiving groove 1213a toward the axis side of the guide sleeve 123. At least two guide grooves 1231 are arranged on the outer circumference of the guide sleeve 123 to match the guide protrusions 1213b. After the guide protrusions 1213b match the guide grooves 1231, the top surface of the bottom support plate 1212 interacts with the lower surface of the roof groove 210. The guide protrusions 1213b are arranged on the groove wall of the receiving groove 1213a, which is conducive to improving the strength of the receiving part 1213, and the guide grooves 1231 are arranged on the guide sleeve 123 for easy processing. The number of the guide protrusions 1213b and the guide grooves 1231 is set to at least two, which is conducive to improving the effect of limiting the rotation between the guide sleeve 123 and the bottom support plate 121. By setting the extension direction of the guide groove 1231 and the guide protrusion 1213b to be along the axial direction of the guide sleeve 123, when the connecting member 122 is rotated, the bottom support plate 121 can move relative to the guide sleeve 123 along the axial direction of the guide sleeve 123, so that the mutual fastening between the pressing block 110 and the metal tile 200 is achieved through the interaction between the bottom support plate 121 and the connecting member 122. After the guide protrusion 1213b is matched with the guide groove 1231, the top surface of the bottom support plate 1212 interacts with the lower surface of the roof groove 210 to prevent the bottom support plate 121 from falling out of the notch of the roof groove 210, and by tightening the connecting member, a pre-tightening force is generated between the bottom support plate 1212 and the connecting member, so that the pressing block 110 and the metal tile 200 are fixed.

[0046] As shown in Fig. 7, in one embodiment, the guide groove 1231 is configured to penetrate the sleeve wall of the guide sleeve 123. Setting the guide groove 1231 to penetrate the sleeve wall of the guide sleeve 123 is conducive to the processing of the guide groove 1231, and is also conducive to the groove matching between the guide protrusion 1213b and the guide groove 1231.

[0047] As shown in Fig. 7, further, there are two guide grooves 1231, and the connecting line of the two guide grooves 1231 in the radial direction of the guide sleeve 123 passes through the axis of the guide sleeve 123. In this way, while ensuring the limiting effect of the guide protrusion 1213b and the guide groove 1231 on the rotation of the bottom support sheet 121, the strength of the guide sleeve 123 can be ensured, and the structure of the guide sleeve 123 is simpler, thereby facilitating processing.

[0048] As shown in Fig. 4, further, the depth of the guide groove 1231 along the axial direction of the guide sleeve 123 is greater than the height of the guide protrusion 1213b along the axial direction of the receiving groove. In this way, when the connecting member 122 is rotated, the bottom support sheet 121 can move a certain travel relative to the guide sleeve 123, thereby ensuring that the pressing block 110 and the metal tile 200 can be fixed by the mutual cooperation between the bottom support sheet 121 and the connecting member 122.

[0049] In one embodiment, the inner diameter of the receiving groove 1213a is larger than the inner diameter of the connecting hole 1211a, so that the receiving groove 1213a defines a limiting step 1213c on one side of the bottom support plate 1212 to limit the movement of the guide sleeve 123. The inner diameter of the receiving groove 1213a is set to be larger than the inner diameter of the connecting hole 1211a, so that the receiving groove 1213a can have a larger space to accommodate the guide sleeve 123. A limiting step 1213c is defined on the bottom support plate 1212 to limit the guide sleeve 123, thereby preventing the guide sleeve 123 from being separated from the bottom support sheet 121 when a pre-tightening force is applied to the connecting member 122.

[0050] As shown in Fig. 6 and Fig. 7, in one embodiment, a limiting plate 1232 is configured at one end of the guide sleeve 123 away from the bottom support sheet 121. The limiting plate 1232 is used to be arranged in the limiting groove 111 of the pressing block 110. The limiting plate 1232 and the groove wall of the limiting groove 111 abut against each other to limit the relative rotation of the guide sleeve 123 and the pressing block 110. The limiting plate 1232 is arranged at one end of the guide sleeve 123 away from the bottom support sheet 121, and the limiting plate 1232 is arranged in the limiting groove 111 on the pressing block 110 to limit the guide sleeve 123, thereby preventing the guide sleeve 123 from rotating relative to the pressing block 110, and thus limiting the rotation of the bottom support sheet 121 relative to the metal tile 200 through the concave-convex fit between the guide groove 1231 on the guide sleeve 123 and the guide protrusion 1213b on the bottom support sheet 121.

[0051] With reference to FIGS. 1 to 8 , the working principle of the mounting block structure provided by the utility model is as follows:

[0052] Put the bottom support piece 121 into the roof groove 210 of the metal tile 200, put the pressing block 110 on the top of the metal tile 200, and then put the guide sleeve 123 into the accommodating groove 1213a of the bottom support piece 121, pass the connecting piece 122 through the guide sleeve 123 and match it with the connecting hole 1211a, rotate the connecting piece 122, and the bottom support piece 121 threadedly matched with the connecting piece 122 moves upward, and when the guide protrusion 1213b matches with the guide groove 1231, the bottom support piece 121 is limited by the guide sleeve 123, so that there is a longitudinal interaction area between the bottom support plate 1212 and the lower surface of the roof groove 210, and the bottom support plate 1212 cannot fall out of the notch of the roof groove 210, and the connecting piece 122 continues to rotate to apply a longitudinal upward force between the pressing block 110 and the bottom support piece 121, so as to realize the connection between the pressing block 110 and the metal tile 200. During this process, once the bottom support piece 121 is limited by the guide sleeve 123, its contact surface with the metal tile 200 is fixed, and the tightening of the connecting piece 122 will not cause relative displacement of the contact surface with the metal tile 200, thereby avoiding wear. At the same time, the two ends of the bottom support plate 1212 will not contact the groove walls on both sides of the roof groove 210, thereby avoiding mutual squeezing damage. After the locking force applied by the connecting piece 122 disappears, the module composed of the connecting piece 122 and the bottom support piece 121 sinks as a whole, and the bottom support piece 121 is out of contact with the metal tile 200. Compared with the prior art, no additional operation is required, and the construction is convenient.

[0053] In other application scenarios, the working principle of the mounting block structure provided by the utility model is as follows:

[0054] First, the pressing block 110 and the connecting assembly 120 are preassembled. At this time, the guide protrusion 1213b and the guide groove 1231 are kept in cooperation. When in use, the length direction of the bottom support sheet 121 is adjusted by rotating the pressing block 110, so that the length direction of the bottom support sheet 121 is consistent with the length direction of the roof groove 210. Then, the bottom support sheet 121 is placed in the roof groove 210, and then the pressing block 110 is rotated, so that the bottom support sheet 121 and the lower groove wall of the roof groove 210 have an interactive area in the longitudinal direction, so as to prevent the bottom support sheet 121 from falling out of the groove of the roof groove 210. Finally, the connecting piece 122 is tightened to lock the pressing block 110 and the metal tile 200. During the tightening process, the position of the pressing block 110 is fixed, the position of the guide sleeve 123 is fixed, and the position of the bottom support piece 121 is fixed. Compared with the prior art, it is easy to operate. During the tightening process, there is no relative displacement between the upper end surface of the bottom support piece 121 and the lower surface of the roof groove 210. The two ends of the bottom support piece 121 in the length direction do not contact the side wall of the roof groove 210, and will not cause damage to the surface of the metal tile 200. The metal tile 200 is protected and the surface damage of the metal tile 200 is avoided, thereby extending the service life of the metal tile 200.

[0055] The utility model also provides a photovoltaic system in one embodiment, which includes the above-mentioned mounting block structure 100. By applying the above-mentioned mounting block structure 100 to the photovoltaic system, a guide groove 1231 and a guide protrusion 1213b are provided on the outer peripheral surface of the guide sleeve 123 and the groove wall of the receiving groove 1213a of the bottom support sheet 121, and the relative rotation of the bottom support sheet 121 and the guide sleeve 123 is limited by the mutual cooperation between the guide protrusion 1213b and the guide groove 1231, thereby limiting the rotation of the bottom support sheet 121 relative to the metal tile 200, so as to prevent the side force of the roof groove 210 of the metal tile 200 from acting on the bottom support sheet 121 to cause the bottom support sheet 121 to deform. When the connecting piece 122 is loosened, the bottom support sheet 121 automatically falls under the action of gravity, which is convenient for rework, thereby improving the installation efficiency.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
