Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic assembly butt joint sealing, in particular to a solar photovoltaic assembly butt joint sealing cover structure. Background Art

[0002] The butt sealing cover structure of solar photovoltaic modules usually involves the sealing connection between the laminate and the frame. The laminate should fit tightly with the frame and ensure a firm connection. There must be good sealing performance between the laminate and the frame to protect the solar cells from the external environment (such as moisture and dust). The assembly between the frames needs to be simple and fast while ensuring the bonding strength. During the assembly process, care should be taken not to damage sensitive parts such as glass.

[0003] In the prior art, a solar photovoltaic module adhesive sealing structure disclosed in the patent with announcement number CN213185999U mainly improves the tightness of the connection between solar panels by providing adhesive grooves and fixing piles.

[0004] It is known from the technology in the related field that for the sealing cover structure of the docking of solar photovoltaic modules, most of them are connected by means of sealant bonding, bolt matching, etc. When docking solar photovoltaic modules, it is necessary to apply glue to control the flow position of the glue, or add rubber pads to seal when bolting; the efficiency is low during docking, and it is cumbersome to fix the solar panels, the fixing effect is poor, and it is inconvenient to use. Utility Model Content

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] The invention discloses a solar photovoltaic assembly butt sealing cover structure, comprising a frame bar, a butt stabilizing unit and a sealing unit.

[0008] Frame bar: There are card openings on both sides, long grooves are equidistantly provided on the inner upper side of the frame bar, straight tubes are equidistantly installed on the frame bar, the long grooves are communicated with the straight tubes, threads are provided on the straight tubes, and steps are provided on the straight tubes; when docking the solar panel, the side of the solar panel is inserted into the card opening, and the inner surface of the card opening is made of rubber.

[0009] The docking and stabilizing unit comprises: it comprises push grooves respectively arranged on both sides of the lower end of the frame bar, the lower ends of the push grooves are installed with elastic sealing plates, rod seats are installed on both sides of the upper end of the long groove, the lower ends of the rod seats are installed with rod shafts, the rod shafts are rotatably connected with push plate rods, the lower end of the long groove is provided with a block guide groove, the inner part of the block guide groove is slidably connected with two corner blocks; the two corner blocks slide symmetrically, and when the two corner blocks move away from each other, the upper ends of the corner blocks contact with the short ends of the push plate rods, forcing the short ends of the push plate rods to move up, and using the lever principle, the long ends of the push plate rods will move downward to continuously apply downward pressure to the solar panel, and at the same time push the sides of the solar panel into the opening of the card.

[0010] Sealing unit: comprising a sealing ring sleeved on the straight barrel. When docking, forcing the sealing ring to deform can improve the sealing effect of the threaded connection.

[0011] Furthermore, the sealing unit further comprises a nut threadedly connected to the straight tube, the interior of the nut is also provided with a step, and a pressure column is installed at the upper end of the interior of the nut. When the nut is turned, the nut drives the pressure column to rotate downward, and the lower end of the pressure column can apply force to the inclined surfaces of the two corner blocks, so that the two corner blocks move away from each other; when the nut is turned, the step inside the nut presses the sealing ring close to the step on the straight tube, which can force the sealing ring to deform and fill the connection gap between the nut and the straight tube.

[0012] Furthermore, the docking and stabilizing unit further comprises a limit bar installed in the middle of the block guide groove, and the limit bar can prevent the two corner blocks from sliding beyond the limit.

[0013] Furthermore, the circumference of the lower end of the pressure column is rounded, and the upper end of the corner block is also rounded. When the circumference of the lower end of the pressure column contacts the inclined surface of the corner block, the movement is smoother, and the rounded corner of the upper end of the corner block can be smoother when the short end of the paddle lever is lifted. The short end of the paddle lever is heavier, and the long end of the paddle lever can be lifted in a natural state.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. In the utility model, the two corner blocks move away from each other, which can make the short end of the plate-shifting rod move upward. By utilizing the principle of lever, the long end of the plate-shifting rod will move downward to continuously apply a downward pressure to the solar panel, and at the same time, the side of the solar panel will be shifted into the opening of the card board. When docking, the fixing effect of the solar photovoltaic module can be further improved, and the stability is stronger.

[0016] 2. In the utility model, when the nut is rotated, the step inside the nut presses the sealing ring close to the step on the straight tube, which can force the sealing ring to deform and fill the connection gap between the nut and the straight tube, thereby improving the sealing effect and preventing water vapor from entering to cause rust, etc. BRIEF DESCRIPTION OF THE DRAWINGS

When docking, the sealing effect of the docking position can be further improved.

[0031] The docking and stabilizing unit comprises a pair of push grooves 4 respectively provided on both sides of the lower end of the frame bar 1, an elastic sealing plate 5 being installed at the lower end of the push groove 4, a rod seat 6 being installed on both sides of the upper end of the long groove 3, a rod shaft 7 being installed at the lower end of the rod seat 6, a push plate rod 8 being rotatably connected to the rod shaft 7, a block guide groove 9 being provided at the lower end of the long groove 3, two corner blocks 10 being slidably connected to the inner part of the block guide groove 9; Figure 2 , Figure 3 and Figure 4 As shown, the two corner blocks 10 slide symmetrically. When the two corner blocks 10 move away from each other, the upper end of the corner block 10 contacts the short end of the lever 8, forcing the short end of the lever 8 to move upward. Using the principle of leverage, the long end of the lever 8 will move downward to continuously apply a downward force to the solar panel, while pushing the side of the solar panel into the card opening 2. When docking, the fixing effect of the solar photovoltaic component can be further improved, and the stability is stronger.

When docking, the nut 13 is rotated, and the nut 13 rotates and moves downward with the pressure column 14. The lower end of the pressure column 14 can apply force to the inclined surfaces of the two corner blocks 10, so that the two corner blocks 10 move away from each other. The upper end of the corner block 10 contacts the short end of the plate-pulling rod 8, forcing the short end of the plate-pulling rod 8 to move upward. Using the principle of leverage, the long end of the plate-pulling rod 8 will move downward to continuously apply downward pressure to the solar panel, and at the same time, the side of the solar panel is pushed into the card opening 2. When docking, the fixing effect of the solar photovoltaic component can be further improved, and the stability is stronger.

[0037] like Figure 3 , Figure 4 and Figure 5 As shown, when the nut 13 is rotated, the step inside the nut 13 presses the sealing ring 12 close to the step on the straight tube 11, which can force the sealing ring 12 to deform and fill the connecting gap between the nut 13 and the straight tube 11, thereby improving the sealing effect, preventing water vapor from entering and causing rust, etc., and further improving the service life.
