Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic power generation devices, in particular to a photovoltaic panel water guide assembly. BACKGROUND

[0002] With the popularization of photovoltaic power generation, more and more photovoltaic power stations are being built. From small residential power generation systems to large commercial and industrial rooftop photovoltaic power generation systems, to large-scale northwest ground photovoltaic power generation systems. In these several use places, there is a common problem: when the angle of the photovoltaic panel is small, a small amount of water on the edge after the rain will absorb dust, thereby reducing the power generation efficiency, or even unable to generate electricity. The design of the water guide assembly can quickly guide the water out even at an angle close to 0 degrees. In a large-area photovoltaic system, the use of manpower can be reduced.

[0003] Chinese patent document CN109617520A discloses a photovoltaic power generation panel drainage device, which comprises a guide piece, the guide piece has a fitting surface and a guide surface connected to each other; the fitting surface comprises a first fitting part and a second fitting part, the plane where the first fitting part is located and the plane where the second fitting part is located intersect, the guide surface comprises a first guide part and a second guide part, the first guide part is connected with the first fitting part, the included angle between the extension direction of the first guide part and the plane where the first fitting part is located is obtuse, the second guide part is connected with the second fitting part, the included angle between the extension direction of the second guide part and the plane where the second fitting part is located is obtuse; a fixing piece, the fixing piece has a first connecting part and a second connecting part, the guide piece is made of a soft material with elasticity and wetness, and the guide piece is made of a soft material with elasticity and wetness. It also includes a screw, the first bottom plate of the fixing piece has a threaded hole, the screw passes through the threaded hole and is threadedly connected with the first bottom plate of the fixing piece.

[0004] The technical defects of the photovoltaic power generation panel drainage device described in CN109617520A are that the guide piece is made of a soft material with elasticity and wetness, and it is difficult for one person to accurately fix the guide piece on the photovoltaic panel (referred to as photovoltaic panel) with the fixing piece at one time, which is prone to loosen, tilt and move, and cannot guarantee the state of the two, and also needs to consider using a screw to pass through the threaded hole, so that the first fitting part of the guide piece is firmly attached to the photovoltaic panel and the upper frame, thereby preventing it from falling off (see paragraph 0053 of the specification). It is often difficult for one person to complete these assembly work well and quickly, and at least two people are often needed to cooperate in the installation, which increases the labor cost.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only the preferred embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative effort shall fall within the scope of the present application.

[0028] Reference Figures 1-6 As shown in the drawings, a water guide assembly of a photovoltaic panel comprises a water guide sheet 2 and a fixing clamp 1. The water guide sheet 2 is provided with a first positioning strip 21 and a second positioning strip 22. The first positioning strip 21 and the second positioning strip 22 are oppositely arranged, and the width between the two is equal to the width of the fixing clamp 1, so that the fixing clamp 1 can be pre-assembled between the first positioning strip 21 and the second positioning strip 22 of the water guide sheet 2.

[0029] Since the first positioning strip 21 and the second positioning strip 22 are oppositely arranged, and the width between the two is equal to the width of the fixing clamp 1, so that the fixing clamp 1 can be pre-assembled between the first positioning strip 21 and the second positioning strip 22 of the water guide sheet 2. In this way, the fixing clamp 1 can be kept in the central position of the water guide sheet 2, and the pre-assembly of the fixing clamp 1 and the water guide sheet 2 can be done before installation. The fixing clamp 1 and the water guide sheet 2 are not loose, inclined or moved, and the state of the two is guaranteed. With the pre-assembly, when the pre-assembly is fixed to the photovoltaic panel 3, there is no need to take and screw the screw again. The pre-assembly can be directly clamped to the edge of the photovoltaic panel 3, which greatly facilitates the installation of the water guide assembly of the photovoltaic panel. One person can quickly install it, and the water guide assembly of the photovoltaic panel only needs two components, without using screws, thereby saving manpower and resources.

[0030] The first positioning strip 21 and the second positioning strip 22 can each be a whole continuous positioning strip. In order to save materials and weight, the first positioning strip 21 and / or the second positioning strip 22 is formed by a plurality of intermittently arranged dot-shaped or line-shaped protrusions. As a preferred specific embodiment, the first positioning strip 21 and the second positioning strip 22 can each be formed by a plurality of intermittently arranged line-shaped protrusions, for example, 3-5 intermittently arranged line-shaped protrusions. In a certain embodiment, 3 intermittently arranged line-shaped protrusions can be selected.

[0031] In terms of materials, the water guide sheet 2 still adopts a soft material with elasticity and wetness. The first positioning strip 21 and the second positioning strip 22 can each be integrally formed on the water guide sheet 2 by the same material. In this way, it is easier to process.

[0032] As a preferred specific embodiment, the water guide sheet 2 comprises a front water-adhering surface 23, a water flow guiding surface 24 and a water draining surface 25 which are integrally formed in sequence, the front water-adhering surface 23 has a curvature for downwardly contacting and adhering to the photovoltaic panel 3, the water flow guiding surface 24 is upwardly transitioned relative to the water flow guiding surface 24, and the angle between the water draining surface 25 and the water flow guiding surface 24 is less than 90 degrees and not less than 85 degrees. For example, the angle between the water draining surface 25 and the water flow guiding surface 24 includes but is not limited to 88.5°, 89°, 89.5°, etc.

[0033] In this embodiment, the front water-adhering surface 23 has a curvature for downwardly contacting and adhering to the photovoltaic panel 3, so that the photovoltaic panel 3 can be fully contacted by the curvature itself; the water flow guiding surface 24 is upwardly transitioned relative to the water flow guiding surface 24, so as to guide the water flow out of the photovoltaic panel 3 and play a guiding role. The angle between the water draining surface 25 and the water flow guiding surface 24 is less than 90 degrees and not less than 85 degrees, so that a gap similar to a horn mouth is formed between the water draining surface 25 and the water flow guiding surface 24, so that the water flow can keep flowing continuously and is not easy to be blocked by foreign matters.

[0034] As a preferred specific embodiment, the water flow guiding surface 24 is provided with integrally formed first arc-shaped surfaces 29 which are outwardly spread on both sides, the water draining surface 25 is provided with integrally formed second arc-shaped surfaces 20 which are outwardly spread on both sides, and the first arc-shaped surfaces 29 and the second arc-shaped surfaces 20 are integrally transitioned and connected. The first arc-shaped surfaces 29 and the second arc-shaped surfaces 20 serve to increase the area of the water flow guiding surface 24, and the outwardly spread first arc-shaped surfaces 29 and the second arc-shaped surfaces 20 also have gaps between them and the photovoltaic panel 3, so that the water flow keeps flowing continuously and is not easy to be blocked by foreign matters during the water flow process.

[0035] As a preferred specific embodiment, the front water-adhering surface 23, the water flow guiding surface 24 and the water draining surface 25 are respectively provided with a first strip-shaped convex surface 26, a second strip-shaped convex surface 27 and a third strip-shaped convex surface 28, the first strip-shaped convex surface 26 has a curvature for downwardly contacting and adhering to the photovoltaic panel 3, and the second strip-shaped convex surface 27 is upwardly transitioned relative to the first strip-shaped convex surface 26; the angle between the third strip-shaped convex surface 28 and the second strip-shaped convex surface 27 is less than 90 degrees and not less than 85 degrees. In this way, the first strip-shaped convex surface 26, the second strip-shaped convex surface 27 and the third strip-shaped convex surface 28 respectively replace the functions of the front water-adhering surface 23, the water flow guiding surface 24 and the water draining surface 25, and increase the gaps between the front water-adhering surface 23, the water flow guiding surface 24 and the water draining surface 25 and the photovoltaic panel 3, so that the water flow keeps flowing continuously and is not easy to be blocked by foreign matters.

[0036] The first, second and third strip-shaped convex surfaces 26, 27 and 28 are integrally connected in sequence to form a strip-shaped convex surface, the width of the strip-shaped convex surface is not greater than the width between the first and second positioning strips 21 and 22, and the position of the strip-shaped convex surface is on the opposite side of the first and second positioning strips 21 and 22. In this way, after the pre-assembly of the fixing clamp 1 and the water guide sheet 2, the pre-assembled part is fixed on the photovoltaic panel 3, and the part between the strip-shaped convex surface and the photovoltaic panel 3 can be further clamped by the fixing clamp 1.

[0037] As a preferred embodiment, the fixing clamp 1 is of type, the front edge of the upper horizontal end has a downward pressing part 11, the tail of the lower horizontal end has an upward clamping protrusion 12. The middle of the upper horizontal end of the fixing clamp 1 is provided with a pressing strip 13. The inner side of the vertical end of the fixing clamp 1 is an outward convex arc surface 14, which can be a slight or appropriate arc surface 14.

[0038] The pressing part 11 presses the front edge of the water guide sheet 2 to the water surface 23, so that the front edge of the water guide sheet 2 is pressed to fit the photovoltaic panel 3, which plays a pressing role; the pressing strip 13 increases the elasticity between the water guide sheet 2 and the fixing clamp 1; the arc surface increases the elasticity of the inner side of the fixing clamp 1; the clamping protrusion 12 has a fixing effect, which is convenient for clamping the fixing clamp 1 on the photovoltaic panel 3 during installation.

[0039] In use, the fixing clamp 1 is positioned between the first and second positioning strips 21 and 22 of the water guide sheet 2, and after pre-assembly, the fixing clamp 1 further clamps the water guide sheet 2 on the photovoltaic panel 3, and the water guide sheet 2 guides the water on the photovoltaic panel 3 out of the panel.
