Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment installation technology, and in particular to a clamp for fixing photovoltaic modules. Background Technology

[0002] Small-scale distributed photovoltaic systems and scattered photovoltaic projects in urban and rural areas are typically characterized by short construction cycles, limited on-site working conditions, strict cost control, and waterproofing requirements. Therefore, they place more urgent demands on the construction efficiency and long-term reliability of the photovoltaic module fixing process. The clamps need to enable the rapid installation of photovoltaic modules to shorten the construction period and reduce labor costs, while also having sufficient load-bearing capacity and structural stability to ensure the long-term reliable operation of photovoltaic modules in complex outdoor environments.

[0003] Currently, the industry commonly uses a double-sided clamping block structure to fix photovoltaic modules. While this structure can achieve basic fixing functions, it has several drawbacks in practical applications: First, it lacks waterproofing performance. There is a gap of about 20mm between the photovoltaic modules connected by the double-sided clamping blocks, allowing rainwater to easily seep in, which is not ideal for projects with waterproofing requirements. Second, it has poor adaptability to different scenarios. This structure is limited to the type of crossbeam it can accommodate, only U-shaped steel beams. When site conditions are limited, the adaptability of construction is greatly reduced, increasing the difficulty and cost of project implementation.

[0004] There is an urgent need for a new type of photovoltaic module fixing clamp that can combine rapid construction, reliable waterproofing, and compatibility with various beam types. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a clamp for fixing photovoltaic modules.

[0006] This fixture for fixing photovoltaic modules includes: bolts and a clamp; a crossbeam is provided inside the clamp, and a photovoltaic module is placed flat on the top of the crossbeam; grooves are provided on the side wall of the clamp, and the frame of the photovoltaic module is fixed in the grooves; the bolts pass through the fixing clamp, the crossbeam and the photovoltaic module from bottom to top.

[0007] Preferably, the clamp is U-shaped with an opening at the bottom through which the bolt passes.

[0008] Preferably, the crossbeam is fixed to the hollow part of the new U-shaped clamp by bolts.

[0009] Preferably, the grooves are opened on both sides of the U-shaped clamp, and the grooves are parallel to the bottom of the clamp; the opening direction of the grooves faces the outside of the photovoltaic module.

[0010] Preferably, the edge of the photovoltaic module frame extends out of or is flush with the side of the clamp.

[0011] The beneficial effects of this utility model are:

[0012] 1) This utility model achieves initial fixation by snapping the photovoltaic module frame into the clamp, and secondary fixation by bolts passing through the clamp. The photovoltaic module, crossbeam and clamp are fixed by bolts, thus realizing rapid construction, reliable load-bearing and secure fixation in simple photovoltaic projects.

[0013] 2) The clamp of this utility model is located below the photovoltaic module, rather than between the photovoltaic modules, which realizes a tight fit between the photovoltaic modules and meets the usage requirements of waterproof projects for sunrooms and carports.

[0014] 3) The clamp of this utility model fixes the crossbeam in the hollow part, and the bolts pass through the crossbeam. The type of crossbeam has no effect on the clamp. There is no need to purchase or modify additional steel beams on site due to the limitation of steel beam type, which greatly improves the construction flexibility. Attached Figure Description

[0020] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0021] As one embodiment, a clamp for fixing photovoltaic modules is proposed, such as... Figure 3 and Figure 4 As shown, the system includes bolts 4 and clamps 6. A crossbeam 2 is located inside the clamp 6, with a photovoltaic module 1 placed flat on top of the crossbeam 2. Grooves are provided on the sidewalls of the clamp 6, and the frame of the photovoltaic module 1 is secured within these grooves, completing the initial positioning of the photovoltaic module 1. Bolts 4 pass through the clamp 6, crossbeam 2, and photovoltaic module 1 sequentially from bottom to top, providing secondary fixation of the photovoltaic module 1 through the bolts 4 penetrating the clamp 6. This achieves rapid construction, reliable load-bearing capacity, and secure fixing in simple photovoltaic projects. The clamp 6, crossbeam 2, and photovoltaic module 1 are fixed using bolts 4, which is convenient and requires fewer parts.

[0022] like Figure 4 As shown, the clamp 6 is U-shaped with an opening at the bottom, through which the bolt 4 passes. Grooves are formed on both sides of the U-shaped clamp 6, parallel to the bottom of the clamp 6. The opening of the grooves faces the outside of the photovoltaic module 1. The crossbeam 2 is fixed to the hollow part of the new U-shaped clamp by bolts 4. The type of crossbeam 2 has no impact on the clamp 6, and there is no need to purchase or modify it on site due to the limitation of the type of steel beam 2, which greatly improves the construction flexibility. The edge of the frame of the photovoltaic module 1 extends out or is flush with the side of the clamp 6, so that the frames of adjacent photovoltaic modules 1 fit together, meeting the usage requirements of sunroom and carport waterproofing projects.

[0023] like Figure 1 and Figure 2 As shown, the traditional fixing method uses clamps consisting of double-sided pressure blocks 3, bolts 4, and plastic wing nuts 5. A photovoltaic module 1 is placed flat on a crossbeam 2. Bolts 4 and plastic wing nuts 5 are threaded onto the double-sided pressure blocks 3, passing through one end of the crossbeam 2 and resting on the frame of the photovoltaic module 1. Another photovoltaic module 1 is moved along the crossbeam 2 to the other end of the double-sided pressure blocks 3 and clamped. Tightening the bolts 4 completes the fixing of the photovoltaic module 1 and the crossbeam 2. The double-sided pressure blocks 3 between the photovoltaic modules 1 result in a 20mm gap between them. Furthermore, due to the use of plastic wing nuts 5, the crossbeam 2 can only be U-shaped. The traditional fixing method suffers from problems such as large gaps between photovoltaic modules 1, poor adaptability of the crossbeam 2, and cumbersome installation procedures. The clamp 6 of this application achieves the technical effects of rapid installation, reliable load-bearing, seamless connection between photovoltaic modules 1, and adaptability to various types of crossbeams 2.
