Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic auxiliary equipment technical field, especially in a new type photovoltaic module middle part compression block subassembly. BACKGROUND

[0002] With the large-scale application of photovoltaic power generation system, the structural reliability of the 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 system operation safety and power generation efficiency.

[0003] The existing reinforcement scheme mainly adopts the C-shaped compression block combined with the 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 purlins 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 compression block is greatly affected by the operation level of the construction personnel, and it is easy to cause uneven reinforcement.

[0004] The alternating stress caused by dynamic wind load also aggravates the metal fatigue of the compression block connection part, leading to the gradual attenuation of the bolt pretightening force, and further causing the resonance risk of the module-support system. In addition, the conventional reinforcement scheme is difficult to adapt to different specifications of the purlin section. UTILITY MODEL CONTENTS

[0028] Embodiment 1

[0029] As Figs. 1-3 shown, the utility model provides a technical scheme:

[0030] A novel photovoltaic module middle pressing block assembly, at least including but not limited to upper pressing block 1 and lower pressing block 2, at least part of the end of upper pressing block 1 is in contact with the top outer side end face of purline 3, the first contact part in contact with the top inner side end face of purline 3 is arranged on lower pressing block 2, the connecting hole is arranged in upper pressing block 1 and lower pressing block 2, and upper pressing block 1 and lower pressing block 2 are locked on the top of purline 3 by connecting bolt 5, and after upper pressing block 1 and lower pressing block 2 are locked, the end of upper pressing block 1 and lower pressing block 2 away from purline 3 abuts, and the left and right sides of upper pressing block 1 are respectively provided with the connecting part connected with photovoltaic module 4.

[0031] Based on the above structure, in the scheme, upper pressing block 1 and lower pressing block 2 abut on the inner and outer side walls of the top of purline 3 respectively, form internal support structure, cooperate with the end of upper pressing block 1 and lower pressing block 2 away from purline 3 abutting, form external support structure, finally make upper pressing block 1 and lower pressing block 2 lock by connecting bolt 5, through internal and external support structure, finally make upper pressing block 1 be able to stably fixed on purline 3, and do not need to carry out the hole of purline 3, guarantee the mechanical property of purline 3, make the whole support system be able to more safely support photovoltaic module 4 under extreme weather conditions.

[0032] As an example, upper pressing 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, 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;First support vertical plate 13 is parallelly arranged at both ends of the length direction of first support horizontal plate.

[0033] Based on the above structure, in use, the part of the plate surface of the first contact horizontal plate 11 is in contact with the outer side wall of the top of the purlin 3, the first supporting vertical plate 12 is arranged on the end surface of the first contact horizontal plate 11 away from the purlin 3, and the second supporting vertical plate 13 is arranged on the end surface of the first contact horizontal plate 11 close to the purlin 3, so that the first contact horizontal plate 11 has more plate surfaces in contact with the top of the purlin 3, and the second contact horizontal plate 14 is used to contact the lower pressing block 2, thereby forming an external support structure.

[0034] 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.

[0035] Based on the above structure, when the first contact horizontal plate 11 is fixed on the purlin 3, a 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, and the parallel arrangement of the first supporting vertical plate 13 can simultaneously support two groups of photovoltaic modules on the left and right sides, which is suitable for the middle end support of the photovoltaic module.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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 on the end of the third contact horizontal plate 21, and the fourth contact horizontal plate 23 is arranged on the end of the third supporting vertical plate 22 away from the third supporting horizontal plate, and the fourth contact horizontal plate 23 is perpendicular to the third supporting vertical plate 22.

[0041] The fourth contact horizontal plate 23 and the third contact horizontal plate 21 are respectively arranged at the opposite ends of the third supporting vertical plate 22, and the fourth contact horizontal plate 23 is arranged in parallel with the third contact horizontal plate 21.

[0042] Based on the above structure, the third contact horizontal plate 21 can provide a supporting basis with the second contact horizontal plate 14, and the parallel arrangement can provide more contact surfaces and increase the supporting force; the fourth contact horizontal plate 23 can increase the contact area between the lower pressing block 2 and the purlin 3, increase the friction therebetween, and make the upper and lower pressing blocks more stable when locked on the purlin 3; and the large contact surface can also reduce the damage to the surface of the purlin 3.

[0043] For example, the first through hole 16 is arranged on the first contact horizontal plate 11, the second through hole 24 is arranged on the third contact horizontal plate 21, and the first through hole 16 and the second through hole 24 are arranged in a matching 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 a whole, the ends of the second contact horizontal plate 14 and the third contact horizontal plate 21 are flush.

[0044] Based on the above structure, the first through hole 16 and the second through hole 24 can play a locking role, and during 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 supporting structure.

[0045] For example, the first through hole 16 is arranged close to the second supporting vertical plate 13.

[0046] Based on the above structure, the special arrangement of the first through hole 16 can make the third supporting vertical plate have a predetermined distance from the purlin 3 when the connecting bolt 5 locks the first through hole 16 and the second through hole 24, so that the third supporting vertical plate has a certain adjusting function, which can adapt to different working environments.

[0047] For example, the size of the second contact horizontal plate 14 can be the same as that of the third contact horizontal plate 21.

[0048] Based on the above structure, the balance of the supporting force of the internal and external supporting structures is ensured, so that the same fixed fatigue life is as possible as possible, and the later maintenance is facilitated.

[0049] The above only describes preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
