Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a dust guide component for a photovoltaic panel. Background Technology

[0002] Dust on the surface of photovoltaic panels can affect their efficiency in absorbing sunlight. Due to the tilted design of the panels, dust and rainwater accumulate at the bottom, blocking sunlight and preventing the bottom area from receiving sunlight. Therefore, a dust guide is usually installed on the bottom edge of the photovoltaic panel to guide water and dust. A common siphon dust guide structure can be found in Chinese utility model patent CN219394780U, which discloses a siphon dust guide assembly for photovoltaic panels. This assembly includes a sheet positioned at the bottom of the photovoltaic panel, with upper and lower clamping plates respectively installed at both ends of the sheet's width direction for holding the photovoltaic panel. A gap is created between the sheet and the photovoltaic panel, and a dust outlet is provided on the lower clamping plate. While this siphon dust guide solves the problem of dust accumulation on the photovoltaic panel surface and achieves good results, its method of fixing to the photovoltaic panel frame with adhesive is prone to detachment due to factors such as the amount of adhesive used, the quality of construction, the weather on the day of construction, and the adhesive's own weather resistance. Especially in Northeast China, due to the cold weather, a large number of dust-guiding components fall off every year, which seriously affects the quality of power plants and their operation and maintenance. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a siphon dust guide component and photovoltaic system that can be installed on a photovoltaic panel, thereby solving the problem that the siphon dust guide component is easy to fall off due to the use of glue for fixing in the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: First, a siphon dust guide component for installation on a photovoltaic panel is provided, including an upper dust guide clamp clamped to the upper side of the photovoltaic panel frame, a lower dust guide clamp clamped to the lower side of the photovoltaic panel frame, and a front dust guide clamp connecting the upper and lower dust guide clamps. The upper, lower, and front dust guide clamps form a dust guide groove. The free end of the upper dust guide clamp extends beyond the inner edge of side A of the photovoltaic panel frame and has a dust guide inlet between it and the surface of the photovoltaic panel. A dust guide gap is provided between the inner side of the dust guide groove and the photovoltaic panel frame. The upper dust guide clamp is provided with an upper buckle that engages with side A of the photovoltaic panel frame, and the lower dust guide clamp is provided with a lower buckle that engages with side C of the photovoltaic panel frame.

[0005] Preferably, the lower buckle includes a lower latching protrusion connected to the end of the lower dust guide clamp away from the front dust guide clamp, and the lower latching protrusion is matched with the inner edge of the C side of the photovoltaic panel frame.

[0006] Preferably, there are two lower dust guide plates, which are arranged on opposite sides of the siphon dust guide component, thereby forming a lower dust guide outlet in the middle, and two lower buckles are provided accordingly.

[0007] Preferably, the lower inner side of the dust guide front clamp is provided with two front protrusions corresponding to the upper side of the two dust guide lower clamps, and the two front protrusions are provided with a lower guide slope on the side of the lower dust guide outlet, so that a flared structure is formed between the two front protrusions.

[0008] Preferably, the upper side of the front boss is provided with a side guide slope, which forms a side dust outlet between the front boss and the dust guide upper clamp.

[0009] Preferably, the upper buckle is provided with at least two; and / or, the upper buckle includes an upper protrusion extending in the front-rear direction and an upper locking protrusion connected to the end of the upper protrusion away from the dust guide front clamp, the upper locking protrusion being limited and engaged with the inner edge of the photovoltaic panel frame A.

[0010] Preferably, the siphon dust guide is an integral structural component.

[0011] Preferably, the free end of the dust guide upper clamp is bent obliquely or arc-shaped toward the surface of the photovoltaic panel.

[0012] Preferably, the free end of the dust guide upper clamp is provided with a serrated portion.

[0013] In addition, a photovoltaic system is provided, including a photovoltaic panel on which the aforementioned siphon dust guide is installed.

[0014] The technical solution adopted in this utility model has the following beneficial effects: 1. The siphon dust guide is installed on the frame of the photovoltaic panel. The free end of the dust guide upper clamp extends beyond the inner edge of side A of the photovoltaic panel frame and has a dust guide inlet between it and the surface of the photovoltaic panel. Since there is a dust guide gap between the inner side of the dust guide groove and the photovoltaic panel frame, dust and water can be introduced from the dust guide inlet, then flow along the dust guide gap, and finally be discharged from the dust guide groove, thus realizing the functions of water and dust guidance.

[0015] The upper dust guide plate has an upper buckle that engages with side A of the photovoltaic panel frame, and the lower dust guide plate has a lower buckle that engages with side C of the photovoltaic panel frame. In this way, both the upper and lower dust guide plates are secured to the photovoltaic panel frame via a buckle structure, making the fixation more reliable and solving the problem of the siphon dust guide components easily falling off.

[0017] 3. The lower inner side of the dust guide front clamp is provided with two front protrusions corresponding to the upper side of the two dust guide lower clamps. The front protrusions cooperate with the B side of the photovoltaic panel frame, so that the dust guide front clamp and the B side of the photovoltaic panel frame form a dust guide gap, and the upper protrusion is fastened to the inner edge of the A side of the photovoltaic panel frame, and the lower protrusion is fastened to the inner edge of the C side of the photovoltaic panel frame.

[0018] Furthermore, there are two dust guide plates on opposite sides of the siphon dust guide component, forming a lower dust guide outlet in the middle. The two front protrusions are provided with a lower guide slope on one side of the lower dust guide outlet, so that a funnel structure is formed between the two front protrusions, that is, the lower dust guide outlet is narrow at the inner end and wide at the outer end, which can enhance the siphon dust guide capacity of the dust guide groove.

[0019] 4. Since the upper side of the front boss is provided with a side guide slope, and a side dust guide outlet is formed between it and the dust guide upper clamping plate, that is, the inner end of the side dust guide outlet is narrow and the outer end is wide, which can enhance the siphon dust guide capacity of the dust guide groove.

[0020] 5. The upper buckle has an L-shaped structure, including an upper protrusion extending in the front-to-back direction and an upper locking protrusion connected to the end of the upper protrusion away from the dust guide front clamp. The upper locking protrusion is matched with the inner edge of the photovoltaic panel frame A to prevent the upper side of the siphon dust guide component from detaching from the photovoltaic panel frame A. In addition, the upper protrusion matches the photovoltaic panel frame A, and forms a dust guide gap between the upper dust guide clamp and the photovoltaic panel frame A.

[0021] 6. The siphon dust guide component is a one-piece structure. It can be made of plastic, such as PO material, which is not only tough and not easy to break, but also corrosion-resistant, thus extending its service life. Of course, it can also be made of other materials, such as stainless steel, aluminum alloy, etc.

[0022] 7. The free end of the dust guide upper clamp is bent obliquely or arc-shaped towards the surface of the photovoltaic panel, and the free end of the dust guide upper clamp is provided with a serrated part. This forms a slit-shaped dust guide inlet, which is conducive to introducing dust and water from the dust guide inlet, and the serrated part has a filtering function to prevent larger debris, such as leaves, from being sucked into the dust guide groove.

[0029] like Figure 1 and Figure 2As shown, this embodiment provides a siphon dust guide 1 installed on a photovoltaic panel 2. The photovoltaic panel 2 is arranged at an angle, and the siphon dust guide 1 is specifically installed on the downward-facing frame 21 of the photovoltaic panel. The photovoltaic panel frame has an upper A side 211, a middle B side 212, and a lower C side 213. The siphon dust guide 1 includes an upper dust guide clamp 11 clamped to the upper side of the photovoltaic panel frame, a lower dust guide clamp 13 clamped to the lower side of the photovoltaic panel frame, and a front dust guide clamp 12 connecting the upper and lower dust guide clamps. The upper dust guide clamp 11, the lower dust guide clamp 13, and the front dust guide clamp 12 form a dust guide groove. The free end of the upper dust guide clamp 11 extends beyond the inner edge of the A side 211 of the photovoltaic panel frame and has a dust guide inlet 112 between it and the surface of the photovoltaic panel. A dust guide gap is provided between the inner side of the dust guide groove and the photovoltaic panel frame 21, and a dust guide outlet is provided.

[0030] The free end of the dust guide plate extends beyond the inner edge of the photovoltaic panel frame A and has a dust guide inlet 112 between it and the photovoltaic panel surface. Since there is a dust guide gap between the inner side of the dust guide groove and the photovoltaic panel frame, dust and water can be introduced from the dust guide inlet 112, then flow along the dust guide gap, and finally be discharged from the dust guide outlet, thus realizing the functions of water and dust guidance.

[0031] In this embodiment, the upper dust guide clamp 11 is provided with an upper buckle 14 that engages with the A side of the photovoltaic panel frame, and the lower dust guide clamp 13 is provided with a lower buckle that engages with the C side 213 of the photovoltaic panel frame. Since both the upper and lower dust guide clamps are engaged and fixed to the photovoltaic panel frame through a buckle structure, the fixation is more reliable, solving the problem of easy detachment of the siphon dust guide component.

[0032] Specifically, the lower clip includes a lower latching protrusion 15 connected to the end of the lower dust guide clamp away from the front dust guide clamp. The lower latching protrusion 15 is engaged with the inner edge of the C-side 213 of the photovoltaic panel frame. In this way, the lower dust guide clamp and the lower latching protrusion together form an L-shaped lower clip, which, together with the front dust guide clamp, forms a U-shaped structure and is firmly fastened to the bottom of the photovoltaic panel frame.

[0033] In this embodiment, two lower dust-guiding clamps 13 are provided on the left and right sides of the siphon dust-guiding component, thereby forming a lower dust-guiding outlet 17 in the middle. Two lower buckles are correspondingly provided. Two front protrusions 16 are provided on the lower inner side of the lower inner side of the front dust-guiding clamp 12, corresponding to the upper sides of the two lower dust-guiding clamps 13. The front protrusions 16 cooperate with the B side 212 of the photovoltaic panel frame, creating a dust-guiding gap between the front dust-guiding clamp and the B side of the photovoltaic panel frame, and simultaneously fastening the upper protrusion to the inner edge of the A side of the photovoltaic panel frame, and the lower protrusion to the inner edge of the C side of the photovoltaic panel frame. Furthermore, a lower guide slope 161 is provided on the side of the lower dust-guiding outlet corresponding to the two front protrusions 16, forming a flared structure between the two front protrusions 16. That is, the lower dust-guiding outlet is narrow at the inner end and wide at the outer end, which enhances the siphon dust-guiding capacity of the dust-guiding groove.

[0034] Furthermore, the upper side of the front boss 16 is provided with a side guide slope 162, which forms a side dust guide outlet 18 between the side guide surface and the dust guide upper clamping plate 11. That is, the side dust guide outlet is narrow at the inner end and wide at the outer end, which can enhance the siphon dust guide capacity of the dust guide groove.

[0035] In this embodiment, at least two upper buckles 14 are provided, three as shown in the figure, one on the left, one in the center, and one on the right, to ensure reliable fastening and fixing between the upper side of the siphon dust guide and the photovoltaic panel frame A side. The upper buckle 14 has an L-shaped structure, including an upper protrusion 141 extending in the front-back direction and an upper locking protrusion 142 connected to the end of the upper protrusion away from the dust guide front clamping plate. The upper locking protrusion 142 is limited and engaged with the inner edge of the photovoltaic panel frame A side 211 to prevent the upper side of the siphon dust guide from detaching from the photovoltaic panel frame A side. In addition, the upper protrusion 141 engages with the photovoltaic panel frame A side 211, and a dust guide gap is formed between the dust guide upper clamping plate 11 and the photovoltaic panel frame A side 211.

[0036] In this embodiment, the siphon dust guide component 1 is a one-piece structural component. It can be made of plastic, such as PO material, which not only has good toughness and is not easy to break, but is also corrosion-resistant, thus extending its service life. Of course, it can also be made of other materials, such as stainless steel, aluminum alloy, etc.

[0037] Specifically, the free end of the dust guide upper clamp 11 is bent obliquely or arc-shaped toward the surface of the photovoltaic panel. Furthermore, the free end of the dust guide upper clamp 11 is provided with a serrated portion 111. This forms a slit-shaped dust guide inlet 112, which facilitates the introduction of dust and water from the dust guide inlet, and the serrated portion has a filtering function, preventing larger debris, such as leaves, from being sucked into the dust guide groove.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above.
