Description

Technical Field

[0001] The utility model relates to a photovoltaic component installation structure and belongs to the field of photovoltaic accessories. Background Art

[0002] In current photovoltaic systems, photovoltaic modules are mostly installed on photovoltaic main beams using U-bolts / clamps in combination with clamps. This installation method is costly on the one hand, and time-consuming and labor-intensive on the other hand, resulting in low installation efficiency.

[0003] In order to solve the above problems, a photovoltaic module installation structure is proposed in the present application. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a photovoltaic component installation structure, which has the advantages of convenient installation and low cost, and can effectively solve the problems in the background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A photovoltaic module mounting structure includes a photovoltaic module, a photovoltaic main beam, and a purlin. The bottom of the photovoltaic module is fixedly connected to the top of the purlin. The purlin is fixedly connected to the photovoltaic main beam through a clamp. The opening of the clamp is locked by a bolt. The photovoltaic module is mounted on the photovoltaic main beam using the clamp in combination with the purlin. Compared with the solution of using U-bolts / clamps in combination with clamps in the prior art, the amount of steel used can be effectively reduced and the cost can be reduced.

[0007] As a further improvement of the present invention, the bottom of the purlin is recessed downward to form a raised portion, and a through hole matching the raised portion is provided on the photovoltaic main beam. The raised portion cooperates with the through hole on the photovoltaic main beam to prevent the clamp from slipping relative to the photovoltaic main beam.

[0008] As a further improvement of the present invention, two mounting holes are opened at the bottom of the purlin, and the mounting holes are located on both sides of the photovoltaic main beam. The clamp passes through the mounting holes on the purlin and then clings to the photovoltaic main beam.

[0009] As a further improvement of the utility model, a connecting head for installing a bolt is provided at the opening of the clamp. The clamp is locked by rotating the thread of the bolt on the connecting head. The tightness of the clamp can be adjusted by adjusting the length of the bolt screwed into the connecting head.

[0010] As a further improvement of the present invention, the screw head of the bolt is configured as a hexagonal structure or is provided with a straight / cross-shaped groove.

[0011] As a further improvement of the utility model, a waist-shaped through hole for installing a photovoltaic module is provided on the top of the purlin.

[0012] The beneficial effects of the utility model: a photovoltaic component installation structure, compared with the structure using clamps for anti-slip in the prior art, effectively reduces the amount of steel used by arranging raised portions on the purlins, and the cooperation between the raised portions and the through holes simultaneously plays the effect of positioning the purlins on the photovoltaic main beams during installation. The rigid U-bolts or clamps in the prior art are replaced by clamps made of flexible materials, thereby avoiding damage to the purlins by the rigid structure under adverse working conditions, reducing the weight of the connection, and being able to adjust the tightness of the connection. During installation, only a number of bolts need to be tightened, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example

[0023] like Figure 1-Figure 5 As shown, a photovoltaic module installation structure includes a photovoltaic module 1, a photovoltaic main beam 2, and a purlin 3. The bottom of the photovoltaic module 1 is fixedly connected to the top of the purlin 3. The purlin 3 is fixedly connected to the photovoltaic main beam 2 by a clamp 4. The opening of the clamp 4 is locked by a bolt 8. The clamp 4 made of a flexible material replaces the rigid U-bolt or clamp in the prior art, thereby avoiding damage to the purlin 3 by the rigid structure under adverse working conditions, reducing the weight of the connection, and the tightness of the connection can be adjusted. During installation, only one bolt 8 needs to be tightened, saving time and effort.

[0024] In some optional embodiments, the bottom of the purlin 3 is recessed downward to form a raised portion 11, and the photovoltaic main beam 2 is provided with a through hole matching the raised portion 11. The raised portion 11 is used in conjunction with the through hole on the photovoltaic main beam 2 to prevent the clamp 4 from slipping relative to the photovoltaic main beam 2. Compared with the structure of using a clamp for anti-slip in the prior art, the amount of steel used is effectively reduced by providing the raised portion 11 on the purlin 3. The cooperation between the raised portion 11 and the through hole also has the effect of positioning the purlin 3 on the photovoltaic main beam 2 during installation.

[0025] Preferably, the raised portion 11 is designed as a hemispherical raised portion with a hollow structure, and the corresponding through hole used in conjunction with the photovoltaic main beam 2 is set as a circular hole. The purlin 3 is formed by stamping and batch stamping, which effectively reduces the processing cost.

[0026] In some optional embodiments, two mounting holes 10 are opened at the bottom of the purlin 3, and the mounting holes 10 are located on both sides of the photovoltaic main beam 2. The clamp 4 passes through the mounting holes 10 on the purlin 3 and is pressed against the photovoltaic main beam 2. The purlin 3 is clamped on the photovoltaic main beam 1 by passing the clamp 4 through the mounting holes 10 on the purlin 3, so that the bottom of the purlin 3 is tightly fitted to the outer wall of the photovoltaic main beam 1, and the fitting effect is better.

[0027] In some optional embodiments, a connecting head 7 for installing a bolt 8 is provided at the opening of the clamp 4, and a threaded hole matching the bolt 8 is provided inside the connecting head 7. The clamp 4 is locked by rotating the thread of the bolt 8 on the connecting head 7.

[0028] In some optional embodiments, the screw head of the bolt 8 is configured to have a hexagonal structure or a straight / cross-shaped groove. In view of the fact that the distance between the bolt 8 and the photovoltaic main beam 2 is very close, a screw head with a hexagonal structure or a screw head with a straight / cross-shaped groove is used to facilitate installation using tools.

[0029] In some optional embodiments, a waist-shaped through hole 9 for installing the photovoltaic module 1 is opened on the top of the purlin 3. The waist-shaped through hole 9 is used in conjunction with the through hole for installation on the photovoltaic module 1, and the photovoltaic module 1 is installed on the purlin 3 by fasteners.

[0030] During installation, the protrusion 11 is placed on the through hole on the photovoltaic main beam 2, and the two ends of the clamp 4 are respectively passed through the mounting holes 10 on the purlin 3 on both sides of the photovoltaic main beam 2, the connecting head 7 is aligned, the bolt 8 is screwed into the connecting head 7 and the connecting head 7 is connected, so that the installation of the clamp 4 is completed, and finally the fastener is passed through the waist-shaped through hole 9 and the photovoltaic component 1 to install the photovoltaic component 1 to the top of the purlin 3. Compared with the installation structure using U-bolts / clamps with clamps in the prior art, the amount of steel used is effectively reduced, the cost is reduced, the installation is convenient, and time and labor are saved.

[0031] The above is a preferred implementation mode of the utility model. The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Technical personnel in this industry should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model to be protected.
