Description

Technical Field

[0001] The present invention relates to the field of photovoltaic module frames, and more specifically, to a hybrid material reinforced photovoltaic module frame. Background Art

[0002] With the continuous increase in the price of aluminum, photovoltaic material manufacturers have rethought the choice of frame materials. Considering material costs and usage effects, new material frames have tried to replace traditional aluminum frames, such as zinc-magnesium-aluminum coated steel frames, polymer frames, etc. Due to the advantages in terms of price, component manufacturers are under pressure to reduce costs and are still trying or have mass-produced them. However, the accompanying problems are also worthy of attention. Steel frames cause various inconveniences in component production. Currently, the steel frames use an outer zinc-magnesium-aluminum coating to protect the steel body, but the corrosion resistance of steel frames during use is still poor. In addition, the high mold cost of polymer frames results in a relatively single frame design, restricting their ability to meet the different needs of different manufacturers.

[0003] In addition, currently, the main direction of components is large size, with both length and width increasing significantly. The aluminum frame has been upgraded from T5 material to T6 material, with an increase in strength. However, with the continuous increase in component size, higher requirements are also put forward for the load-bearing capacity of the aluminum frame. Therefore, it is necessary to propose a hybrid material reinforced photovoltaic module frame to solve the problems existing in the prior art. Summary of the Invention

[0026] It should be understood that the terms such as "having", "including" and "comprising" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0027] As Figure 1 shown, the present invention provides a frame of a photovoltaic module reinforced with a hybrid material, including: an aluminum alloy frame and a reinforcing beam 6. The aluminum alloy frame includes a bottom plate 1, side plates 2, support plates 3, pressing plates 4 and vertical plates 5. The bottom plate 1, support plates 3 and pressing plates 4 are fixedly connected to one side of the side plates 2. The pressing plates 4 and the bottom plate 1 are respectively fixed to the upper and lower ends of the side plates 2. The support plates 3 are fixed at a position above the middle of the side plates 2. The support plates 3, pressing plates 4 and the bottom plate 1 are arranged in parallel. The vertical plates 5 are arranged between the bottom plate 1 and the support plates 3. A reinforcing cavity is formed between the vertical plates 5 and the side plates 2, bottom plate 1 and support plates 3. The reinforcing beam 6 is arranged in the reinforcing cavity. An installation groove is formed between the pressing plates 4 and the support plates 3 and side plates 2. The reinforcing beam is made of steel or polymer fiber.

[0028] Working principle of the above technical solution: Aluminum alloy frame and reinforcing beam 6. The aluminum alloy frame includes a bottom plate 1, side plates 2, support plates 3, pressing plates 4 and vertical plates 5. The bottom plate 1, support plates 3 and pressing plates 4 are fixedly transferred to the side plates 2. The support plates 3 and pressing plates 4 are arranged parallel to the bottom plate 1. The vertical plate 5 is arranged between the bottom plate 1 and the support plates 3. A reinforcing cavity is formed between the vertical plate 5, the side plates 2, the bottom plate 1 and the support plates 3. The reinforcing beam 6 is arranged in the reinforcing cavity. An installation groove is formed between the pressing plate 4, the support plate 3 and the side plates 2. The photovoltaic panel is installed in the installation groove. The reinforcing beam can be made of steel or polymer fiber material.

[0029] Beneficial effects of the above technical solution: The reinforcing beam strengthens the strength of the aluminum alloy frame, can reduce the overall wall thickness and height of the aluminum alloy frame, reduce the frame material cost. Using steel to make the reinforcing beam has high strength and low cost. Using polymer fiber to make the reinforcing beam can reduce the overall weight of the frame.

[0030] In one embodiment, the surface of the aluminum alloy frame is an anodic oxidation layer.

[0031] Working principle of the above technical solution: The primary anodic oxidation used is to use aluminum alloy as the anode in an acidic electrolyte and stainless steel etc. as the cathode. Under the condition of applying a certain voltage or current, an oxide layer with a micron-level thickness is formed on the surface of the aluminum alloy matrix. This layer structure is denser and presents a certain configuration.

[0032] The aluminum alloy anodic oxidation electrolyte includes the following components: 40 - 60 g / L sulfuric acid; 8 - 20 g / L organic weak acid; 5 - 30 ml / L accelerator; water is used as the solvent in the electrolyte. Here, the organic weak acid has its inherent meaning in the field, generally referring to organic acids with an acidity coefficient pKa greater than 4.

[0033] The organic weak acid is oxalic acid, acetic acid, malic acid, gluconic acid or citric acid, more preferably citric acid. The addition of the organic weak acid can improve the structure of the oxide layer and obtain an oxide layer with finer pores than that of sulfuric acid anodic oxidation. However, when the dosage of the organic weak acid is too low, the structure of the oxide layer is rough, and when the dosage is too high, the pores of the porous layer of the oxide layer will become larger and the corrosion resistance will decrease.

[0034] The accelerator is titanium sol, silica sol or zirconium sol. The addition of the accelerator can effectively improve the size of the pores of the oxide layer, make the pores of the oxide layer more uniform, and at the same time the surface of the oxide layer is smoother, thereby improving the corrosion resistance of the oxide layer.

[0035] Use eddy current thickness measurement method to detect the thickness of the anodic oxidation layer. A high-frequency electromagnetic field is generated by a high-frequency alternating current coil installed in the measurement probe placed on the oxide layer, so that an eddy current value is generated in the non-magnetic metal conductor under the insulating layer. The size of this eddy current value is quantitatively related to the thickness of the layer.

[0036] At the selected high frequency, the anodic oxidation layer thickness δ is inversely proportional to the capacitance value C in a functional relationship:

[0037]

[0038] Wherein, δ is the anodic oxidation layer thickness; A is the surface area of the oxidation layer; ε is the dielectric constant of the oxidation layer, π is the ratio of the circumference of a circle to its diameter. After anodizing the aluminum alloy frame, the density of the anodic oxidation layer is detected.

[0039] The detection of the density of the anodic oxidation layer includes:

[0040] Obtaining an X-ray image of the anodic oxidation layer of the aluminum alloy frame;

[0041] Constructing a grayscale histogram corresponding to the X-ray image of the anodic oxidation layer and calculating the gradient of each pixel point on the X-ray image of the anodic oxidation layer;

[0042] Using the following formula to calculate the gradient of each pixel point on the X-ray image of the anodized aluminum alloy frame:

[0043]

[0044] Where: H is the gradient of the i-th pixel point on the X-ray image of the anodized aluminum alloy frame, t is the grayscale threshold, G is the minimum grayscale value of the pixel point on the X-ray image of the anodized aluminum alloy frame, x i is the grayscale value of the i-th pixel point on the X-ray image of the anodized aluminum alloy frame, and e is the base of the natural logarithm.

[0045] Clustering the pixel points on the X-ray image of the anodized aluminum alloy frame whose gradients are less than or equal to the set threshold to obtain the area with the lowest density on the X-ray image of the anodized aluminum alloy frame;

[0046] Encoding the pixel points in the area with the lowest density, and counting the number of jumps of the pixel points in the area with the lowest density; calculating the correlation of the pixel points in the area with the lowest density according to the number of jumps and the number of pixel points of the pixel points in the area with the lowest density.

[0047] Encoding the pixel points in the area with the lowest density: the pixel points belonging to the marked pixel points are encoded as 1, and the pixel points not belonging to the marked pixel points are encoded as 0 to establish a row sequence; the marked pixel points are the pixel points on the X-ray image of the anodic oxidation layer whose gradients are greater than or equal to the set threshold, and counting the number of jumps of the pixel points from 1 to 0 in the row sequence.

[0048] Using the following formula to calculate the correlation of the pixel points in the area with the lowest density:

[0049]

[0050] Where: S is the correlation degree of the pixel points in the area with the lowest density, N is the number of jumps of the pixel points in the area with the lowest density, β is the number of pixel points in the area with the lowest density, and α is the number of marked pixel points in the area with the lowest density.

[0051] Calculate the density of the anodic oxidation layer of the aluminum alloy frame according to the correlation degree of the pixel points in the area with the lowest density.

[0052] Use the following formula to calculate the density of the anodic oxidation layer of the aluminum alloy frame:

[0053]

[0054] Where: T is the density of the anodic oxidation layer of the aluminum alloy frame, S is the correlation degree of the pixel points in the area with the lowest density, A is the total number of marked pixel points on the X-ray image of the anodic oxidation layer of the aluminum alloy frame, and B is the total number of pixel points on the X-ray image of the anodic oxidation layer of the aluminum alloy frame.

[0055] Compare the calculated density T of the anodic oxidation layer of the aluminum alloy frame with the set density threshold of the anodic oxidation layer of the aluminum alloy frame. If T is greater than the density threshold of the anodic oxidation layer of the aluminum alloy frame, the anodic oxidation layer of the aluminum alloy frame is qualified; otherwise, the anodic oxidation layer of the aluminum alloy frame is qualified and needs to be subjected to secondary anodic oxidation treatment. The density threshold of the anodic oxidation layer of the aluminum alloy frame can be selected as 0.8.

[0056] The aluminum alloy frame with a qualified anodic oxidation layer is subjected to high-temperature over-sealing treatment. In deionized water at 100 degrees Celsius, boil to seal the anodic oxidation layer, and the treatment time is 30 minutes.

[0057] Advantages of the above technical solution: The anodic oxidation operation is simple and low-cost. The anodic oxidation layer has strong corrosion resistance, high hardness, is not easily scratched during use or handling, has good wear resistance and is not easily worn during use. The anodic oxidation layer is a porous structure and has strong adsorption ability, and various pigments, lubricants, resins, etc. can be filled into the pores to further improve the protection, insulation, wear resistance and decorative performance of the aluminum product. The anodic oxidation layer is non-conductive and has good insulation.

[0058] In one embodiment, there are reinforcing ribs in the reinforcing cavity.

[0059] Working principle of the above technical solution: Reinforcing ribs are arranged in the reinforcing cavity.

[0060] Advantages of the above technical solution: By arranging reinforcing ribs in the reinforcing cavity, the strength of the aluminum alloy frame is improved. The reinforcing ribs are closely attached to the reinforcing beam, so that the reinforcing beam is fixed in the reinforcing cavity. Arranging the reinforcing ribs can...

[0061] In one embodiment, the reinforcing beam 6 is a hollow rectangle.

[0062] Working principle of the above technical solution: The reinforcing beam is a hollow rectangle. The reinforcing beam can be made of steel or polymer fibers. The reinforcing beam can be made of steel or high polymer fibers according to the usage scenario. The length of the reinforcing beam can be the same as that of the aluminum alloy frame, or the length of the reinforcing beam can be selected according to needs, but the length of the reinforcing beam cannot exceed the length of the aluminum alloy frame. For example, the length is selected to be the same as the position between the supports of the aluminum alloy frame. The position of the aluminum alloy frame support refers to the position where the aluminum alloy frame is fixed after the photovoltaic panel is installed.

[0063] Beneficial effects of the above technical solution: By adding a reinforcing beam in the reinforcing cavity, the wall thickness and height of the aluminum alloy frame can be reduced, the amount of frame material used can be reduced, the cost can be reduced, and the overall strength of the frame can be increased. The steel is inside the aluminum alloy frame, avoiding contact with the external harsh environment and improving the service life of the steel.

[0064] In one embodiment, the reinforcing beam 6 and the aluminum alloy frame are fixed by stamping, and the stamping positions are evenly distributed on the horizontal center line of the vertical plate 5.

[0065] Working principle of the above technical solution: The reinforcing beam and the aluminum alloy frame are fixed by stamping. At the position of the reinforcing beam outside the vertical plate of the reinforcing cavity, at an interval of a set distance, the vertical plate is stamped at the position of the center height of the reinforcing cavity to form a stamping pit on the vertical plate. An inward depression is formed on the inner side of the vertical plate at the stamping position to form a stamping protrusion, and the stamping protrusion presses tightly on the reinforcing beam, and the reinforcing beam and the aluminum alloy frame are fixed together.

[0066] Beneficial effects of the above technical solution: After the reinforcing beam and the aluminum alloy frame are fixed by stamping, the reinforcing beam can be prevented from moving in the reinforcing cavity. Using the stamping method for fixing is simple and low-cost.

[0067] In one embodiment, a sealing groove 10 is provided on the pressing plate 4.

[0068] Working principle of the above technical solution: A sealing groove is provided on the pressing plate, and a sealing strip can be provided in the sealing groove to prevent rainwater and impurities from entering the installation groove of the aluminum alloy frame.

[0070] In one embodiment, a storage capsule is provided inside the installation groove. The storage capsule includes a resin storage capsule 12 and a curing agent storage capsule 13. The resin storage capsule 12 is adhered to the side plate of the installation groove, and the curing agent storage capsule 13 is adhered to the pressing plate 4 and the supporting plate 3 of the installation groove respectively.

[0071] The working principle of the above technical solution: A storage capsule is provided inside the installation groove. The storage capsule includes a resin storage capsule 12 and a curing agent storage capsule 13. The resin storage capsule 12 is adhered to the side plate of the installation groove, and the curing agent storage capsule 13 is adhered to the pressing plate 4 and the supporting plate 3 of the installation groove respectively. The storage capsule can be made of PE material, and its thickness can be selected according to the length of the aluminum alloy frame. The longer the length, the thicker the wall thickness can be selected. The thickness of the storage capsule is between 50 and 150 microns.

[0072] The beneficial effect of the above technical solution: By pre-setting the storage capsule in the installation groove, when manufacturing the aluminum alloy frame, the aluminum alloy frame is made according to the specifications of the photovoltaic panel and the storage capsule is pre-set.

When installing the photovoltaic panel, the photovoltaic panel pushes the needle plate to move. The needle pins on the needle plate pierce the storage capsule. The resin glue and the curing agent in the storage capsule are extruded from the storage capsule. Under the further pressure of the needle plate, the resin glue and the curing agent are mixed and enter the gap between the photovoltaic panel and the installation groove through the glue outlet hole and the glue guide groove.
