Description

Technical Field

[0001] This utility model relates to the field of steel frame technology, specifically to an open-section steel frame for photovoltaic modules. Background Technology

[0002] Energy conservation and emission reduction have become increasingly important. Traditional photovoltaic module frames are made of aluminum alloy. However, the electrolysis of aluminum in the production process is a high-energy-consuming step, requiring approximately 13,500 kWh of electricity to electrolyze one ton of aluminum, while producing one ton of steel requires only 4,500 kWh. Therefore, steel consumes only one-third the energy of aluminum alloy, and its carbon emissions are far lower. The continuously rising price of aluminum has increased the cost of aluminum alloy frames, while the price increase of steel has lagged behind that of aluminum. Against this backdrop, steel frames for photovoltaic modules with zinc-aluminum-magnesium coatings have emerged.

[0003] In existing photovoltaic module steel frames, the connection between the steel frame and the corner bracket mainly relies on the friction between the teeth on the corner bracket and the steel frame. This frictional force results in poor connection stability and a tendency for the structure to loosen. Therefore, an open-section steel frame for photovoltaic modules is proposed.

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing open-section steel frames for photovoltaic modules, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an open-section steel frame for photovoltaic modules, in which interlocking cards and slots are provided at the connection inflection points of the frame body. After the corner brackets are connected, the frame bodies are interlocked together by the cards and slots, so that the inflection points of the frame body chain structure are stably connected, avoiding structural loosening that could cause the photovoltaic panels to fall off, and ensuring the connection stability of the frame.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] This utility model provides an open-section steel frame for photovoltaic modules. Interlocking cards and slots are provided at the connection inflection points of the frame body. After corner bracket connection, the frame bodies are interlocked by the cards and slots, ensuring a stable connection at the inflection points of the frame body chain structure. This prevents structural loosening that could cause the photovoltaic panel to detach, thus ensuring the connection stability of the frame. Please refer to [link to relevant documentation]. Figures 1-5 It includes: border component 100 and corner code component 200.

[0031] The border assembly 100 includes a border body 110, a card 120, a card slot 130, and a groove 140. The end of the border body 110 is provided with a card 120 and a card slot 130 that fit together, and the groove 140 is provided on the inner side of the border body 110.

[0032] Specifically, the frame body 110 is divided into a long frame and a short frame. One end of the long frame is a card 120 and the other end is a card slot 130. One end of the short frame is a card 120 and the other end is a card slot 130. After being assembled, the card 120 and the card slot 130 fit together.

[0033] In addition, such as Figure 5 As shown, the border body 110 also includes ten types (101 to 111) shown in the figure, which can be selected and used according to needs.

[0034] The corner code component 200 is set at the connection inflection point of the frame body 110. Specifically, the corner code component 200 includes a corner code 210, a movable groove 220, a lead screw 230, a push block 240, a slider 250, and an insert block 260. The movable groove 220 is set on the inner side of the corner code 210, the lead screw 230 is set at the corner of the corner code 210, the push block 240 is set at one end of the lead screw 230 located in the movable groove 220, the slider 250 is set on both sides of the movable groove 220, and the insert block 260 is slidably connected to both the upper and lower ends of the outer end of the movable groove 220. The slider 250 and the insert block 260 are provided with corresponding ramps.

[0035] The movable groove 220 is an L-shaped groove, and the lead screw 230 is screwed onto the corner bracket 210. A handle is provided at the end of the lead screw 230 outside the movable groove 220. The handle is an internal hexagonal handle. The push block 240 is a conical block. An elastic element is provided between the insert blocks 260. In its natural state, the insert block 260 is submerged inside the corner bracket 210. By rotating the lead screw 230 through the handle, the push block 240 is moved under the action of threaded feed, causing the push block 240 to move inward into the movable groove 220. When the push block 240 moves, it presses the slider 250, causing the slider 250 to move outward. The outwardly moving slider 250 presses the insert block 260 through the ramp, causing the insert block 260 to slide out from the corner bracket 210. The slid-out insert block 260 is fitted into the groove 140, ensuring connection stability.

[0036] In practical use, the frame body 110 is divided into a long frame and a short frame, which are spliced ​​together. When splicing, the corner code component 200 is inserted into the inside of the corner point. After the frame body 110 is spliced, the card 120 and the card slot 130 are fitted together. Then, the screw 230 is rotated by the handle, and the push block 240 is moved under the action of the thread feed, so that the push block 240 moves inward into the movable slot 220. When the push block 240 moves, it squeezes the slider 250, so that the slider 250 moves outward. The outward slider 250 squeezes the insert 260 through the ramp, so that the insert 260 slides out from the corner code 210. The slid-out insert 260 is fitted into the slot 140 to ensure the connection stability.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
