Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a combined structure of a dust guide groove and a snow separation piece of a photovoltaic component. Background Art

[0002] Dust on the surface of photovoltaic modules will affect the efficiency of photovoltaic modules in absorbing sunlight. Since photovoltaic modules are tilted, dust and rainwater will accumulate at the bottom, blocking the bottom of the photovoltaic panel, resulting in the bottom area of ​​the photovoltaic panel not receiving sunlight. Therefore, the frame at the bottom of the photovoltaic module is usually equipped with a dust guide groove to achieve the water and dust guide functions. With reference to the Chinese utility model patent with the authorization announcement number CN219394780 U, a siphon dust guide assembly of a photovoltaic panel is disclosed, including a sheet body arranged at the lower part of the photovoltaic panel, an upper clamping plate and a lower clamping plate for clamping the photovoltaic panel are respectively installed at both ends of the sheet body in the width direction, the sheet body and the photovoltaic panel are arranged in a gap, a dust discharge port is provided on the lower clamping plate, and a sawtooth portion extends outward from one end of the upper clamping plate away from the sheet body, and the sawtooth portion abuts against the upper surface of the photovoltaic panel on the side away from the upper clamping plate. The abutment of the sawtooth portion can make water and dust be sucked out of the photovoltaic panel through the siphon effect generated by the bottom surface of the sawtooth portion, and discharged through the gap between the sheet body and the photovoltaic panel and the dust discharge port, and the impurities are discharged by the self-weight of water and dust combined with the siphon effect.

[0003] In addition, the photovoltaic module has a relatively smooth surface to prevent dust accumulation from affecting power generation, which makes snow more likely to slide after snowing. However, snow usually accumulates in piles and slides down under its own weight. If the snow slides down without intervention, it will threaten the lives and property of temporary buildings and passers-by on the ground. Therefore, a snow blocking and snow dividing piece is usually designed. Referring to the Chinese utility model patent with the announcement number CN215818036 U, a snow blocking clamp for photovoltaic modules is disclosed, including a clamp body; the clamp body includes a first clamping edge and a clamping edge assembly, the first clamping edge and the clamping edge assembly form a first clamping groove for clamping the lower frame of the photovoltaic module; the clamping edge assembly includes a second clamping edge and a third clamping edge, the second clamping edge and the third clamping edge form a second clamping groove for clamping the lower edge of the lower frame of the photovoltaic module. In this way, large pieces of snow can be blocked and divided, solving the safety risk problem caused by large pieces of snow sliding down on the surface of the photovoltaic module, ensuring personal safety and avoiding property losses.

[0004] However, in the prior art, the dust guide member and the snow separation member are separately provided and installed, which increases the overall cost of the photovoltaic system. Utility Model Content

[0009] Preferably, one of the connecting portion and the dust guiding groove is provided with a slot, and the other is provided with a plug, and the plug is plugged into the slot.

[0010] Preferably, a slot extending laterally is provided on the upper side of the dust guide on the upper side of the frame, and a plug is provided on the bottom end of the snow separating piece; or, a slot extending laterally is provided on the front side of the dust guide, and a plug is provided on the lower rear side of the snow separating piece.

[0012] Preferably, the upper side of the dust guide is provided with a laterally extending insert on the upper side of the frame, and the bottom of the snow separating piece is provided with a slit groove, and the slit groove is inserted into the insert.

[0013] Preferably, a step portion is provided at the bottom end of the snow distributing member, the step portion comprises a convex surface on the front side and a concave surface on the rear side, and the slit groove is provided at the junction of the concave surface and the convex surface.

[0014] Preferably, the snow separating portion is provided with a snow separating angle on the side facing the accumulated snow to slide down; and / or, the dust guiding groove and the snow separating member are both made of PO material.

[0015] Preferably, the free end of the upper side of the dust guide is bent obliquely or in an arc shape toward the surface of the photovoltaic module; and / or, a protrusion is provided on the inner side of the dust guide groove to form a dust guide gap between the inner side of the dust guide groove and the frame.

[0016] The technical solution adopted by the utility model has the following beneficial effects:

[0017] 1. The dust guide groove is snap-fitted and installed on the frame of the photovoltaic module, and the snow separator is installed on the dust guide groove, forming a dust guide and snow separator combined structure, wherein the free end of the upper side of the dust guide extends beyond the inner edge of the upper side wall of the photovoltaic module frame and has a dust guide inlet between the surface of the photovoltaic module, and because a dust guide gap is provided between the inner side of the dust guide groove and the photovoltaic module frame, dust and water can be introduced from the dust guide inlet, then flow along the dust guide gap, and finally discharged, thereby realizing the water and dust guide functions. The snow separator is provided with a snow separator part for dividing the fallen snow, which can block and divide large pieces of snow, thereby avoiding the safety risks caused by large pieces of snow falling on the surface of the photovoltaic module.

[0019] 3. Since the slot extends horizontally, during installation, the plug is inserted into the slot from the opening at one horizontal end of the slot and moved horizontally until it is installed in place. The advantage of horizontal plug-in installation is that the plug-in direction is perpendicular to the direction of snow sliding, which prevents the plug and the slot from loosening and falling off due to the impact of snow.

[0020] 4. Since the slot is a T-slot and the plug is a T-head, it is not only easy to plug in and out, but also reliable and not easy to loosen or separate.

[0021] 5.

[0022] 6. The step portion at the bottom end of the snow separating piece includes a convex surface on the front side and a concave surface on the rear side, wherein a slit groove is arranged at the junction of the concave surface and the convex surface, so that the convex surface extends downward beyond the bottom end of the insert, thereby increasing the effective area between the dust guide groove and improving the reliability of the connection between the two.

[0023] 7. A snow separation angle is provided on the side of the snow separation part facing the sliding snow. In this way, the snow separation angle first inserts into the large pieces of snow sliding down from the surface of the photovoltaic module, which is conducive to the snow separation part to divide the snow.

[0024] 8. Since the dust guide groove and snow separation parts are made of PO material, they are not only tough and not easy to break, but also corrosion-resistant, thus extending their service life.

[0025] 9. Since the free end of the upper side of the dust guide is bent obliquely or in an arc shape toward the surface of the photovoltaic module, a slit-shaped dust guide inlet is formed, which is conducive to introducing dust and water from the dust guide inlet.

[0026] 10. Since a protrusion is provided on the inner side of the dust guide groove, a dust guide gap is formed between the inner side of the dust guide groove and the frame.

[0046] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] Embodiment 1

[0048] like Figures 1 to 5As shown, a combined structure of dust guide and snow separation of photovoltaic modules includes a dust guide groove 1 and a snow separation member 2 installed on the dust guide groove 1, wherein the dust guide groove 1 includes a dust guide upper side 11, a dust guide lower side 13 and a dust guide front side 12 connecting the dust guide upper side 11 and the dust guide lower side 13, the dust guide groove 1 is snap-fitted and installed on the photovoltaic module frame 100, the free end of the dust guide upper side 11 extends beyond the inner edge of the upper side wall of the photovoltaic module frame and has a dust guide entrance 200 between the photovoltaic module surface, a dust guide gap 300 is provided between the inner side of the dust guide groove 1 and the photovoltaic module frame 100, and the snow separation member 2 includes a connecting portion 21 connected to the dust guide groove 1 and a snow separation portion 22 for separating the fallen snow. Usually, the lower half of the snow separation member 2 is the connecting portion 21, and the upper half is the snow separation portion 22, because the snow separation portion 22 needs to exceed the height of the lower surface of the photovoltaic module upwards, so as to block and separate the large pieces of snow sliding off the surface of the photovoltaic module.

[0049] Among them, the free end of the upper side of the dust guide extends beyond the inner edge of the upper side wall of the photovoltaic module frame and has a dust guide inlet between the surface of the photovoltaic module, and because a dust guide gap is provided between the inner side of the dust guide groove and the photovoltaic module frame, dust and water can be introduced from the dust guide inlet, then flow along the dust guide gap, and finally discharged, thereby realizing the water and dust guiding functions. The snow dividing member is provided with a snow dividing portion for dividing the sliding snow, which can block and divide large pieces of snow, thereby avoiding the safety risks caused by large pieces of snow sliding off the surface of the photovoltaic module. In this way, the function of the dust guide groove is expanded, and one item can be used for multiple purposes, thereby achieving the purpose of saving the overall cost of the photovoltaic system.

[0050] In order to facilitate the combination, the connecting part 21 is detachably connected to the dust guide groove 1. Specifically, the connecting part 21 is plug-connected with the dust guide groove 1, wherein one of the connecting part 21 and the dust guide groove 1 is provided with a slot, and the other is provided with a plug, and the plug is plugged into the slot. This facilitates the assembly and installation of the snow separation component and the dust guide groove, and also facilitates the removal of the snow separation component for replacement.

[0051] In this embodiment, the dust guide upper side 11 is provided with a slot extending transversely on the upper side of the frame, and the bottom end of the snow separation member 2 is provided with a plug. When installing, the plug is inserted into the slot from the opening at one transverse end of the slot and moved transversely to be installed in place. The advantage of transverse insertion is that the insertion direction is perpendicular to the direction of snow sliding down, so as to avoid the plug and the slot being loosened and falling off due to the impact of snow.

[0052] Specifically, the slot is a T-slot 16, and the plug is a T-head 24, which is not only convenient to plug in, but also reliable to fit and not easy to loosen and separate. In this embodiment, a T-slot 16 is provided on the front side of the dust guide, and a T-head 24 is provided on the lower rear side of the snow splitter. Compared with connecting the snow splitter on the upper side of the dust guide, this can have a larger connection area, increase the reliability of the connection, and make installation more convenient.

[0053] Furthermore, the snow dividing portion 22 may be provided with a snow dividing angle 23 on the side facing the snow. For example, the snow dividing portion may be provided with a triangular structure on the side facing the snow. In this way, the snow dividing angle firstly inserts into the large snow falling from the surface of the photovoltaic module, which is conducive to the snow dividing portion to divide the snow.

[0054] Preferably, the dust guide groove 1 and the snow separation member 2 are both made of PO material. Not only is it tough and not easy to break, but it is also corrosion-resistant, thus extending the service life. Of course, it can also be made of other materials, such as stainless steel, aluminum alloy, etc.

[0055] Referring to the dust guide groove structure in the prior art, the free end of the upper side of the dust guide is bent obliquely or in an arc shape toward the surface of the photovoltaic module to form a bending portion 14. Thus, a slit-shaped dust guide inlet is formed, which is conducive to the introduction of dust and water from the dust guide inlet. In addition, a protrusion 15 is provided on the inner side of the dust guide groove 1 to form a dust guide gap between the inner side of the dust guide groove and the frame. Specifically, the protrusion 15 is in the shape of a convex strip, extending along the inner side of the dust guide groove as a whole, that is, from the upper side of the dust guide, along the front side of the dust guide to the edge of the lower side of the dust guide.

[0056] The photovoltaic module is tilted as a whole, and a dust guide and snow separation combination structure can be installed on each of the lateral sides of the lower side frame of the photovoltaic module, and a dust guide and snow separation combination structure can also be installed in the lateral middle of the lower side frame of the photovoltaic module. Of course, the dust guide and snow separation combination structure can also be installed in other positions.

[0057] Embodiment 2

[0058] like Figures 6 to 9 As shown, the difference from the first embodiment is that a slot extending transversely is provided on the dust guide front side 12, and a plug is provided on the lower rear side of the snow separation member 2. Of course, the slot is also a T-shaped slot, and the plug is also a T-shaped head. Compared with the snow separation member connected to the upper side of the dust guide front side in the first embodiment, this can reduce the area of ​​the snow separation member and reduce the cost of the snow separation member.

[0059] In addition, other structures can refer to the first embodiment and will not be described in detail here.

[0060] Embodiment 3

[0061] like Figures 10 to 13 As shown, the difference from the first embodiment is that the structure of the slot and the plug is different. Specifically, the dust guide upper side 11 is provided with a laterally extending plug 17 on the upper side of the frame, and the bottom of the snow divider 2 is provided with a slit groove 25, and the slit groove 25 is plugged with the plug 17. In this way, after the slit groove is aligned with the plug, the snow divider can be pressed from top to bottom to make the slit groove and the plug plug, which is convenient for the snow divider to be assembled and installed with the dust guide groove, and also convenient for disassembling the snow divider for replacement.

[0062] Furthermore, the bottom end of the snow distributing member 2 is provided with a step portion, the step portion includes a convex surface 211 on the front side and a concave surface 212 on the rear side, and the slit groove 25 is provided at the junction of the concave surface and the convex surface. In this way, the convex surface extends downward beyond the bottom end of the insert, thereby increasing the interaction area between the dust guide groove and improving the reliability of the connection between the two.

[0063] In addition, other structures can refer to the first embodiment and will not be described in detail here.

[0064] The above embodiments illustrate that the connection structure between the connection part and the dust guide groove can adopt various forms. Of course, it can be understood that it is not limited to the plug-in connection mentioned above, and other detachable connection methods can also be used, and even the dust guide groove and the snow separation part can be made into an integral part.

[0065] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
