Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy material application, and in particular relates to an aluminum profile used for a photovoltaic support system. Background Art

[0002] Photovoltaic support system refers to the support frame used to install photovoltaic panels. The material of photovoltaic support system is generally made of light and strong aluminum profiles.

[0003] On the other hand, the essential structure of the photovoltaic support system is the support bar, which is used to set up the photovoltaic panel. On the support bar, a pressing block can be further arranged to further reinforce the photovoltaic panel.

[0004] In addition, if the photovoltaic support system itself is not erected on a wall or other location, but needs to be installed independently, a column structure needs to be set on the above-mentioned support bar. Finally, the support bar, the lower pressure block and the column can form a relatively complete photovoltaic support system. Of course, various reinforcement structures can also be set in the photovoltaic support system as needed.

[0005] For example, a Chinese utility model patent with authorization announcement number CN220544897U and authorization announcement date 2024.02.27 discloses an aluminum profile for fixing a photovoltaic bracket, including a bottom plate frame, a vertical plate frame is arranged on one side of the bottom plate frame, and an inclined plate frame is connected to one side of the vertical plate frame, a first groove is formed inside the vertical plate frame, and a side frame is connected to the top of the vertical plate frame, a hollow groove is formed between the side frame, the vertical plate frame and the inclined plate frame, and the top of the side frame is connected to the top frame.

[0006] The photovoltaic bracket aluminum profile in this utility model patent has the following structural principles and advantages: two sets of relatively arranged inclined plate frames are used to form a triangular structure inside the profile, which can maintain the stable shape of the structure and provide better support for the profile during the stress process, which can effectively ensure that the structure of the profile in supporting the photovoltaic panel is more stable, and the first groove provided can effectively remove various liquid residues on the surface of the profile.

[0007] However, in actual use, the photovoltaic bracket aluminum profile still has at least the following two shortcomings, which are also the technical problems to be solved by the utility model, namely:

[0008] First, the top skeleton structure can only provide basic support for the photovoltaic panels, but cannot press down and fix the photovoltaic panels, so the fixing and installation strength of the photovoltaic panels is relatively poor;

[0009] Second, the first groove structure is relatively far away from the upper surface of the photovoltaic panel, so it is unable to quickly collect and accommodate dust on the upper surface, and it is even more unable to quickly discharge the dust and debris, which will eventually reduce the power generation efficiency of the photovoltaic panel.

[0010] So in summary, there is an urgent need for a new type of aluminum profile that has sufficient photovoltaic panel fixing strength and can temporarily store and quickly discharge dust as part of the photovoltaic support system. Utility Model Content

[0011] The utility model provides an aluminum profile for a photovoltaic support system, which can achieve the following by arranging a sliding block unit and a combined panel unit on an upper opening frame unit: 1. The photovoltaic panel obtains an upper and lower combined fixing effect on the aluminum profile, ensuring that the photovoltaic panel is not easy to fall off; 2. The upper opening frame unit can conveniently collect dust originally on the photovoltaic panel and quickly discharge the dust, so that the photovoltaic panel is always relatively clean and not covered by dust and debris, thereby ultimately improving the efficiency of photovoltaic power generation.

[0012] The technical solution adopted by the utility model to solve the above-mentioned problem is: an aluminum profile for a photovoltaic support system, the structure of which includes an upper opening frame unit for collecting and accommodating dust on the upper surface of the photovoltaic panel, a sliding block unit that is snap-fitted on the upper opening frame unit and used to press down the photovoltaic panel, and a combined panel unit that is arranged on the upper opening frame unit and used to vertically support and laterally limit the photovoltaic panel.

[0013] A further preferred technical solution is that the upper opening frame unit includes a base plate, an outer vertical plate arranged on the base plate, an inner vertical plate arranged on the base plate and used for installing the combined plate unit, and two end plates respectively arranged on the outer vertical plate and the inner vertical plate and used for engaging the sliding block unit.

[0014] A further preferred technical solution is that the sliding block unit includes a main block arranged on the upper surfaces of the two end plates and used to press down the photovoltaic panel, and two bending blocks arranged on the lower surface of the main block and used to engage the two end plates respectively.

[0015] A further preferred technical solution is that the combined panel unit includes an L-shaped panel arranged on the inner vertical panel and used to vertically support the photovoltaic panel, and a protruding panel arranged on the inner vertical panel and used to laterally limit the photovoltaic panel.

[0016] A further preferred technical solution is that the upper opening frame unit also includes a U-shaped plate whose two ends are respectively arranged on the lower surfaces of the two end plates and is used to collect and accommodate dust on the upper surface of the photovoltaic panel.

[0017] A further preferred technical solution is that the upper opening frame unit also includes a vertical support plate arranged on the bottom plate and the U-shaped plate.

[0018] A further preferred technical solution is that: the sliding block unit further includes a mounting hole arranged on the main block and located between the two bending blocks.

[0019] A further preferred technical solution is that the upper opening frame unit also includes a first screw hole arranged on the bottom plate.

[0020] A further preferred technical solution is that the upper opening frame unit also includes a second screw hole arranged on the U-shaped plate.

[0021] A further preferred technical solution is that the number of the upper opening frame units is 1 or 2. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0035] As attached Figure 1-8 As shown, an aluminum profile for a photovoltaic support system has a structure including an upper opening frame unit 1 for collecting and accommodating dust a on the upper surface of a photovoltaic panel, a sliding block unit 2 which is snap-fitted on the upper opening frame unit 1 and used to press down the photovoltaic panel b, and a combined panel unit 3 which is arranged on the upper opening frame unit 1 and used to vertically support and laterally limit the photovoltaic panel b.

[0036] In this embodiment, the open frame unit 1 and the combined plate unit 3 are integrally formed, and the sliding block unit 2 is a separate part, and both are made of aluminum alloy.

[0037] The "upper opening" structure of the upper opening frame unit 1 is used to collect dust a on the upper surface of the photovoltaic panel to ensure that the upper surface of the photovoltaic panel b is as clean as possible, and the collection method is manual cleaning or natural wind blowing. Finally, the dust can be discharged at the end opening of the aluminum profile, or it can be discharged outward over the side of the "upper opening" structure. However, the latter method is only applicable when the aluminum profile is used as the side of the photovoltaic support system.

[0038] In addition, the aluminum profile can be mounted on a wall when in use, or a lower column can be arranged on the upper opening frame unit 1. The general usage of the aluminum profile is:

[0039] First, it can be used as the middle support position of the multiple photovoltaic panels b arranged linearly, and can also be used as the side support position. All aluminum profiles are used in parallel, that is, the photovoltaic panels b are only supported and fixed by the aluminum profiles on two symmetrical sides;

[0040] Second, a single combined panel unit 3 can support 4-10 photovoltaic panels b at the same time, and one side of each photovoltaic panel b is pressed down and reinforced by 1-2 sliding block units 2.

[0041] The upper opening frame unit 1 includes a bottom plate 101, an outer vertical plate 102 arranged on the bottom plate 101, an inner vertical plate 103 arranged on the bottom plate 101 and used for installing the combined plate unit 3, and two end plates 104 respectively arranged on the outer vertical plate 102 and the inner vertical plate 103 and used for engaging the sliding block unit 2.

[0042] In this embodiment, the upper opening frame unit 1 and the combined plate unit 3 constitute a single component, and the sliding block unit 2 itself, both of which have no visible dividing line between the above-mentioned plates on their cross sections. Figure 4 The dividing lines shown are for relative clarity only.

[0043] The cross-sectional profile of the upper opening frame unit 1 is rectangular, and dust a on the upper surface of the photovoltaic panel can be collected, temporarily stored and discharged in the "U-shaped" structure composed of the bottom plate 101, the outer vertical plate 102 and the inner vertical plate 103.

[0044] In addition, the two end plates 104 simultaneously clamp and fix the sliding block unit 2 in the vertical and lateral directions, so that the sliding block unit 2 can only slide in the length direction of the upper opening frame unit 1, and then select the appropriate position of pressing down the corresponding photovoltaic panel b.

[0045] The sliding block unit 2 includes a main block 201 arranged on the upper surfaces of the two end plates 104 and used to press down the photovoltaic panel b, and two bending blocks 202 arranged on the lower surface of the main block 201 and used to engage the two end plates 104 respectively.

[0046] In this embodiment, the main block 201 is rectangular in shape, and the cross-sectional shape of the bending block 202 is L-shaped. The two together engage the end plate 104, thereby ultimately making it possible for: the end of the main block 201 that is different from the end where the bending block 202 is set to be able to resist or approach the upper surface of the photovoltaic panel b, thereby preventing the photovoltaic panel b from falling after being separated upward on the photovoltaic support system.

[0047] The combined panel unit 3 includes an L-shaped plate 301 disposed on the inner vertical plate 103 and used to vertically support the photovoltaic panel b, and a protruding plate 302 disposed on the inner vertical plate 103 and used to laterally limit the photovoltaic panel b.

[0048] In this embodiment, the L-shaped plate 301, the protruding plate 302 and the main block 201 act on the aluminum alloy frame of the photovoltaic panel b and will not touch the photovoltaic power generation body of the photovoltaic panel b.

[0049] Among them, the conventional photovoltaic panel b has a frame structure with a cross-sectional shape of a rectangle or a lateral U-shape, that is, Figure 7 and attached Figure 2 In the attached Figure 7 In this case, both the protruding plate 302 and the upper opening frame unit 1 need to and can store and discharge dust a on the upper surface of the photovoltaic panel.

[0050] In the attached Figure 2 In this case, the protruding plate 302 does not need to collect dust a on the upper surface of the photovoltaic panel, but it should be noted that the lateral protrusion amplitude of the protruding plate 302 needs to correspond to the lateral groove depth of the frame of the photovoltaic panel b to ensure that the protruding plate 302 and the inner vertical plate 103 can together support and fix the photovoltaic panel b.

[0051] The upper opening frame unit 1 also includes a U-shaped plate 105 whose two ends are respectively arranged on the lower surfaces of the two end plates 104 and is used to collect and contain dust a on the upper surface of the photovoltaic panel.

[0052] In this embodiment, the main function of the U-shaped plate 105 is to form a closed cavity in the upper opening frame unit 1, so that the structural strength of the upper opening frame unit 1 is improved.

[0053] However, it should be noted that the dust a on the upper surface of the photovoltaic panel, which could originally be collected and discharged on the bottom plate 101, can now only be collected and discharged on the U-shaped plate 105, the latter being smaller than the former, resulting in a slight reduction in the dust collection and discharge capacity. Therefore, the length and width of the U-shaped plate 105 should not be too small.

[0054] The upper opening frame unit 1 further includes a vertical support plate 106 disposed on the bottom plate 101 and the U-shaped plate 105 .

[0055] In this embodiment, the upper end of the vertical support plate 106 is connected to the middle bottom plate portion of the U-shaped plate 105 , thereby reinforcing the upper opening frame unit 1 .

[0056] The sliding block unit 2 further includes a mounting hole 203 disposed on the main block 201 and located between the two bending blocks 202 .

[0057] In this embodiment, the function of the mounting holes 203 is to allow the screws c to be replaced with bolts. At this time, the upper opening frame unit 1 also needs to have aligned mounting holes.

[0058] The upper opening frame unit 1 further includes a first screw hole 107 disposed on the bottom plate 101 .

[0059] In this embodiment, the mounting hole 203 needs to be used together with the first screw hole 107 to ensure that the sliding block unit 2 can be fixedly installed in the length direction of the upper opening frame unit 1 .

[0060] At this time, the hardware used for fixing the installation can be bolts and screws. And whether the mounting hole 203 is provided with threads can also be used.

[0061] The upper opening frame unit 1 further includes a second screw hole 108 disposed on the U-shaped plate 105 .

[0062] In this embodiment, after the second screw hole 108 is opened, it does not matter whether the first screw hole 107 is opened or not, as long as the screw c is ensured to have at least one screw connection position on the upper opening frame unit 1 .

[0063] The number of the upper opening frame units 1 is 1 or 2.

[0064] In this embodiment, according to different usage locations, the aluminum profiles can be divided into the following two categories: bracket system side panels and bracket system middle panels.

[0065] When the aluminum profile is the former, the number of the upper opening frame unit 1 is 1. When the aluminum profile is the latter, the number of the upper opening frame unit 1 is 2. For example, see the attached Figure 8 .

[0066] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
