The limiting section 23 is connected to the other end of the connecting section 22, and the limiting section 23 is adapted to extend into the frame 42. For example, in the examples of fig. 1 and 2, the front end of the connection section 22 is connected to the fixed section 21, and the rear end of the connection section 22 is connected to the stopper section 23 in the first direction. So arranged, by providing the fixing section 21, the connection structure 2 can be firmly connected with the connection portion 12, thereby enhancing the fixing effect of the connection portion 12 to the connection structure 2. In addition, the structure of the connecting structure 2 is simple, and the production difficulty of the connecting structure 2 is reduced, so that the production cost of the connecting structure 2 is reduced, and the production efficiency of the connecting structure 2 is improved.
Alternatively, referring to fig. 2, the cross-sectional area of the stopper section 23 is larger than the cross-sectional area of the connecting section 22. And/or the cross-sectional area of the fixed section 21 is larger than the cross-sectional area of the connecting section 22. For example, the arrangement of the cross sections of the limiting section 23, the connecting section 22 and the fixing section 21 includes the following cases: the cross-sectional area of the first, stop segment 23 is greater than the cross-sectional area of the connecting segment 22. The cross-sectional area of the second, stationary section 21 is larger than the cross-sectional area of the connecting section 22. The cross-sectional area of the third, spacing section 23 is greater than the cross-sectional area of the connecting section 22, and the cross-sectional area of the stationary section 21 is greater than the cross-sectional area of the connecting section 22. By this arrangement, the contact area between the fixing section 21 and the connecting portion 12 is increased, thereby improving the strength of the connection of the connecting structure 2 and the connecting portion 12. In addition, the area of the limiting section 23 extending into the frame 42 is increased, so that the connection strength of the connecting structure 2 and the frame 42 is enhanced, and the stabilizing effect of the pressing block 100 on the photovoltaic module 4 is further enhanced. In addition, the connecting section 22 strengthens the connection between the fixing section 21 and the limiting section 23, and meanwhile, the cross section area of the connecting section 22 is smaller, so that the material consumption of the connecting section 22 can be reduced, the production cost of the connecting structure 2 is reduced, and the production cost of the pressing block 100 is further reduced.
According to some embodiments of the present utility model, referring to fig. 1, the fixing portion 13 is located at a side of the connection portion 12 remote from the pressing portion 11. For example, in the example of fig. 1, the fixing portion 13 is connected to the lower side of the connecting portion 12. When the pressing block 100 is used for the photovoltaic module 4, the fixing part 13 can be connected with the bracket 3 to fix the pressing block 100, so that the use stability of the pressing block 100 is improved, and the compaction stability of the pressing block 100 on the photovoltaic module 4 is also improved.
A photovoltaic power generation system 200 according to an embodiment of the second aspect of the present utility model, referring to fig. 1, includes a bracket 3, a photovoltaic module 4, and a briquette 100.
Specifically, the photovoltaic module 4 is provided on the holder 3. The photovoltaic module 4 includes a photovoltaic body 41 and a frame 42, and the frame 42 is provided around the photovoltaic body 41. The press block 100 is the press block 100 according to the first aspect of the embodiment of the present utility model, the fixing portion 13 of the press block 100 is connected to the bracket 3, the pressing portion 11 of the press block 100 is abutted against the top of the frame 42, the connecting portion 12 of the press block 100 is located at the outer peripheral side of the frame 42, and the connecting structure 2 of the press block 100 is connected to the frame 42. For example, in the example of fig. 1, the fixing portion 13 is fixedly connected to the bracket 3 by a bolt, and the lower surface of the pressing portion 11 is abutted against the upper surface of the top of the frame 42. Therefore, the pressing part 11 presses the frame 42 downwards through the stopping of the pressing part 11 and the top of the frame 42, so that the frame 42 can be effectively prevented from being turned inwards, and the use stability of the frame 42 is improved. The connection portion 12 may limit the movement of the frame 42 in the front-rear direction. In addition, the connection structure 2 increases the connection strength of the pressing block 100 and the rim 42 and provides a tensile force to the rim 42, thereby effectively preventing the rim 42 from slipping down and being turned in.
According to some embodiments of the present utility model, referring to fig. 2, the frame 42 includes a mounting groove 421 and a receiving cavity 422, the edge of the photovoltaic body 41 is fitted into the mounting groove 421, a second mounting hole 4221 penetrating a side surface of the receiving cavity 422 facing the connection part 12 is formed on the frame 42, and the other end of the connection structure 2 is fitted into the receiving cavity 422 through the second mounting hole 4221. For example, in the example of fig. 2, an end of the connecting section 22 remote from the fixing section 21 passes through the second mounting hole 4221 so that the limiting section 23 is fitted in the receiving cavity 422. The left side wall of the accommodating cavity 422 is abutted against the left side surface of the limiting section 23. Thus, on the one hand, by providing the second mounting hole 4221, the limiting segment 23 can be quickly and accurately inserted into the receiving cavity 422, thereby facilitating quick assembly of the press block 100 and the rim 42. On the other hand, the inner wall of the accommodating cavity 422 has a limiting effect on the limiting section 23 so as to prevent the limiting section 23 from falling off from the frame 42, thereby effectively preventing the connecting structure 2 from falling off from the frame 42, further enhancing the connection strength between the connecting structure 2 and the frame 42, effectively preventing the photovoltaic module 4 from sliding downwards, and further improving the stability of the photovoltaic module 4.
According to some embodiments of the present utility model, referring to fig. 2, the central axis of the other end of the connection structure 2 is arranged offset from the central axis of the second mounting hole 4221. For example, in the example of fig. 2, the above-described other end of the connection structure 2 is the end of the connection structure 2 remote from the connection portion 12. The assembly process of the connection structure 2 and the frame 42 is generally as follows: the central axis of the other end of the connecting structure 2 is aligned with the central axis of the second mounting hole 4221, then the connecting structure 2 is moved towards the direction close to the frame 42, so that one end of the limiting section 23 and the connecting section 22, which is far away from the fixed end, passes through the second mounting hole 4221 until the limiting section 23 stretches into the accommodating cavity 422, and then the connecting structure 2 is moved downwards, so that the central axis of the limiting section 23 is staggered with the central axis of the second mounting hole 4221, and the limiting section 23 is in abutting fit with the inner wall of the accommodating cavity 422. Therefore, the limit section 23 can be effectively prevented from falling from the second mounting hole 4221, and the assembly stability of the connecting structure 2 and the frame 42 is further enhanced, so that the stability of the photovoltaic module 4 in long-term use is further improved.
