Description
TECHNICAL FIELD
[0001] The utility model relates to photovoltaic auxiliary equipment technical field, especially in a kind of novel photovoltaic module end block subassembly. BACKGROUND
[0002] With the large-scale application of photovoltaic power generation system, the structural reliability of module frame under extreme weather conditions faces severe challenges. The traditional aluminum frame is prone to structural failure problems such as frame tearing and profile deformation in areas with high wind pressure due to insufficient structural strength, especially in the photovoltaic power station that has been built. Such damage will directly affect the safety of system operation and power generation efficiency.
[0003] The existing reinforcement scheme mainly uses C-shaped block with purlin opening fixing method. This technology has multiple limitations in practical application. First, the support system of the power station in production is mostly pre-processed and shaped. Secondary drilling needs to overcome the risk of positioning deviation, and the on-site processing of high-strength steel purlin requires special equipment, which significantly reduces the construction efficiency. Second, repeated drilling will weaken the structural strength of the purlin, affecting the overall stability of the support system. Third, the tightening effect of the traditional block is greatly affected by the operation level of the construction personnel, and it is easy to have uneven reinforcement.
[0004] The alternating stress caused by dynamic wind load also aggravates the metal fatigue of the block connection part, leading to the gradual attenuation of the bolt pre-tightening force, and further causing the risk of resonance of the module-support system. In addition, the conventional reinforcement scheme is difficult to adapt to different specifications of purlin cross-section. UTILITY MODEL CONTENTS

[0027] Embodiment 1
[0028] As Figs. 1-2 shown in the technical scheme provided by the utility model discloses a technical scheme:
[0029] A novel photovoltaic module end block assembly, which at least includes but is not limited to upper block 1 and lower block 2, at least part of the end of upper block 1 is in contact with the top outer side end face of purlin 3, the first contact part in contact with the top inner side end face of purlin 3 is arranged on lower block 2, and connecting holes are arranged in upper block 1 and lower block 2, and upper block 1 and lower block 2 are locked on the top of purlin 3 through connecting bolt 5, and after upper block 1 and lower block 2 are locked, the end of upper block 1 and lower block 2 away from purlin 3 abuts, and the connecting part connected with photovoltaic module 4 is further arranged on upper block 1.
[0030] Based on the above structure, in the scheme, upper block 1 and lower block 2 abut on the inner and outer side walls of the top of purlin 3 respectively, form an internal support structure, and cooperate with the end of upper block 1 and lower block 2 away from purlin 3 to abut, form an external support structure, finally, upper block 1 and lower block 2 are locked through connecting bolt 5, through the internal and external support structures, finally, upper block 1 can be stably fixed on purlin 3, and purlin 3 does not need to be holed, the mechanical properties of purlin 3 are guaranteed, and the entire support system can support photovoltaic module 4 more safely under extreme weather conditions.
[0031] As an example, upper block 1 can include first contact horizontal plate 11, first support vertical plate 12, second support vertical plate 13 and second contact horizontal plate 14, first support vertical plate 12 and second support vertical plate 13 are connected with the upper and lower end faces of first contact horizontal plate 11 respectively, and second contact horizontal plate 14 is connected with second support vertical plate 13.
[0032] Based on the above structure, in use, part of the plate surface of first contact horizontal plate 11 is in contact with the outer side wall of the top of purlin 3, first support vertical plate 12 is arranged on the end face of first contact horizontal plate 11 away from purlin 3, second support vertical plate 13 is arranged on the end face of first contact horizontal plate 11 close to purlin 3, so that more plate surfaces of first contact horizontal plate 11 are in contact with the top of purlin 3, and second contact horizontal plate 14 is used to contact lower block 2, forming an external support structure.
[0033] As an example, the first limiting plate 15 is arranged on the end surface of the first supporting vertical plate 12 away from the first contact horizontal plate 11, and the first limiting plate 15 is arranged on the opposite side of the first contact horizontal plate 11 on the first supporting vertical plate 12.
[0034] Based on the above structure, when the first contact horizontal plate 11 is fixed on the purlin 3, the cavity structure for limiting the photovoltaic module 4 is formed between the first limiting plate 15 and the outer side wall of the purlin 3, so that the photovoltaic module 4 can be fixed in the cavity between the first limiting plate 15 and the purlin 3.
[0035] As an example, the connecting edge of the first supporting vertical plate 12 and the first contact horizontal plate 11 is adjacent to the connecting plate of the second supporting vertical plate 13 and the first contact plate, and is integrally formed.
[0036] Based on the above structure, by arranging the first supporting vertical plate 12 and the second supporting vertical plate 13 on different sides, they can play different roles in different directions, that is, the second supporting plays a supporting role, and the first supporting vertical plate 12 plays a limiting and matching role for the photovoltaic module 4, and the two are integrally formed, so that the structure of the entire upper pressing block 1 is more stable, and when locked by the connecting bolt 5, the structural support performance can be more stable.
[0037] As an example, the overall structure of the first limiting plate 15 is a trapezoidal structure, and the end of the first limiting plate 15 away from the first supporting vertical plate 12 is a trapezoidal structure.
[0038] Based on the above structure, the end of the first limiting plate 15 is arranged as a sharp trapezoidal structure, which can reduce the space size of the end, and provide flexible reserved space for subsequent system assembly and clearance between components.
[0039] As an example, the lower pressing block 2 can include a third contact horizontal plate 21, a third supporting vertical plate 22, and a fourth contact horizontal plate 23; the third supporting vertical plate 22 is vertically arranged at the end of the third contact horizontal plate 21, and the fourth contact horizontal plate 23 is arranged on the third supporting vertical plate 22 away from the end of the third supporting horizontal plate, and the fourth contact horizontal plate 23 is perpendicular to the third supporting vertical plate 22.
[0040] The fourth contact horizontal plate 23 and the third contact horizontal plate 21 are respectively arranged on the opposite ends of the third supporting vertical plate 22, and the fourth contact horizontal plate 23 is arranged parallel to the third contact horizontal plate 21.
[0041] Based on the above structure, by setting the third contact horizontal plate 21 can be supported with the second contact horizontal plate 14 to provide a basis, both parallel can have more contact surface, increase the supporting degree; by setting the fourth contact horizontal plate 23 can increase the contact area of the lower pressing block 2 and the purlin 3, increase the friction of the two, when the upper and lower pressing blocks are locked on the purlin 3, it can be more stable, and the larger contact surface, it can also reduce the damage to the surface of the purlin 3.
[0042] As an example, the first contact horizontal plate 11 is provided with a first through hole 16, and the third contact horizontal plate 21 is provided with a second through hole 24, and the first through hole 16 and the second through hole 24 are matched in position, when the connecting bolt 5 passes through the first through hole 16 and the second through hole 24 to connect the upper pressing block 1 and the lower pressing block 2 into one, the ends of the second contact horizontal plate 14 and the third contact horizontal plate 21 are flush.
[0043] Based on the above structure, the first through hole 16 and the second through hole 24 can play a locking role, and at the same time in the pre-locking process, the ends of the second contact horizontal plate 14 and the third contact horizontal plate 21 are flush, which can ensure that the first contact horizontal plate 11 and the fourth contact horizontal plate 23 are located in the same vertical plane at the upper and lower ends of the purlin 3, so as to ensure the strength of the internal support structure.
[0044] As an example, the first through hole 16 is arranged close to the second support vertical plate 13.
[0045] Based on the above structure, the position of the first through hole 16 is specially arranged, so that when the connecting bolt 5 locks the first through hole 16 and the second through hole 24, the third support vertical plate can be spaced apart from the purlin 3 by a predetermined distance, so that the third support vertical plate can have certain adjustment function, so as to adapt to different working environments.
[0046] As an example, the size of the second contact horizontal plate 14 and the size of the third contact horizontal plate 21 can be the same.
[0047] Based on the above structure, so as to ensure that the supporting degree of the internal and external support structures is balanced, so that they have the same fixed fatigue life as much as possible, which is convenient for later maintenance.
[0048] The above only describes the preferred embodiments of the present application, and does not limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
