Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, in particular to a water-guiding and mud-draining clamp used for photovoltaic modules. Background Art

[0002] Photovoltaic modules generally refer to solar cell modules. Because individual solar cells have low output voltages and unpackaged cells are susceptible to electrode shedding due to environmental influences, a certain number of these cells must be sealed together in series and parallel to form a solar cell module. This prevents corrosion of the cell electrodes and interconnects. Furthermore, encapsulation prevents cell breakage and facilitates outdoor installation. The quality of the encapsulation determines the lifespan and reliability of the solar cell module.

[0003] Dirt on the surface of photovoltaic modules can block some sunlight, reducing power generation efficiency and affecting the performance of the entire photovoltaic system. Regular cleaning of photovoltaic modules increases operating costs and can damage the modules during the cleaning process. In rainy or humid areas, moisture on the modules combines with dirt to form a conductive layer, causing potential differences, increasing the risk of hot spot effects, and even damaging the modules.

[0004] However, existing water and mud deflector clamps have relatively long tail wings that are nearly parallel to the deflector plates. This means they can only be installed from the sides of the photovoltaic panels. However, for large numbers of existing power plants, this requires disassembling and reinstalling panels, which is labor-intensive, time-consuming, and labor-intensive. Utility Model Content

[0005] In view of this, the utility model provides a water guide and mud drainage clamp for photovoltaic modules to solve the problem of time-consuming and labor-intensive installation of water guide and mud drainage clamps in an already built power station.

[0006] The utility model provides a water guide and mud removal clamp for a photovoltaic module, which includes a photovoltaic panel arranged obliquely and brackets respectively arranged at the upper and lower ends of the photovoltaic panel, the brackets are connected to a support plate and a limit plate located above the support plate, and the end of the photovoltaic panel is inserted between the support plate and the limit plate, including:

[0007] connecting arm;

[0008] a deflector, arranged at the end of the connecting arm;

[0009] The stopper is clipped between the guide plate and the connecting arm, which abuts the side of the bracket at the bottom of the photovoltaic panel. During installation, the connecting arm is placed against the side of the bracket at the bottom of the photovoltaic panel, and the guide plate is pressed down so that the stopper is clipped between the guide plate and the connecting arm. This allows the water and mud drainage clamp to be installed on the photovoltaic panel. It does not require installation from the side of the photovoltaic panel and can be installed directly in the gap of an existing power station, saving time and effort.

[0010] In an optional embodiment, the connecting arm is provided with beveled serrations on the contact surface with the bracket. The beveled serrations can increase the friction between the connecting arm and the bracket, and improve the fastening between the water-guiding and mud-draining clamp and the photovoltaic module.

[0011] In an optional embodiment, the surface of the guide plate near the connecting arm has an envelope surface, and the limit plate is engaged between the envelope surface and the connecting arm. The envelope surface can envelop the surface of the guide plate near the connecting arm, and pressing the guide plate downward causes the limit plate to engage between the envelope surface and the connecting arm.

[0012] In an optional embodiment, the envelope surface is adapted to the shape of the top surface of the limiting plate.

[0013] In an optional embodiment, a first groove is provided on a surface of the guide plate away from the envelope surface.

[0014] In an optional embodiment, the first groove is located at a middle position of the guide plate away from the envelope surface.

[0015] In an optional embodiment, a portion of the envelope surface opposite to the first groove is connected to the connecting arm.

[0016] In an optional embodiment, two second grooves are provided on the surface of the guide plate away from the envelope surface, and the first groove and the second groove are connected.

[0017] In an optional embodiment, two second grooves are respectively arranged on both sides of the first groove.

[0018] In an optional embodiment, two shells are further included, which are respectively arranged on the outer sides of the two second grooves relative to the first groove.

[0019] The first groove, the second groove and the shell together guide muddy water. The shell can guide high water levels, and the first groove and the second groove can guide low water levels. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0026] The following combination Figures 1 to 2 , describing the embodiments of the present utility model.

[0027] According to an embodiment of the present utility model, a water-conducting and mud-draining clamp for a photovoltaic assembly is provided. The photovoltaic assembly includes an inclined photovoltaic panel and brackets respectively arranged at the upper and lower ends of the photovoltaic panel. A support plate and a limit plate located above the support plate are connected to the bracket. The end of the photovoltaic panel is inserted between the support plate and the limit plate, and includes:

[0028] Connecting arm 1;

[0029] The guide plate 2 is disposed at the end of the connecting arm 1. A baffle may also be provided on the connecting arm 1, connected to the guide plate 2. The baffle can be considered to be at the junction of the connecting arm 1 and the guide plate 2. The connecting arm 1 widens along both sides. The angle between the connecting arm 1 and the guide plate 2 can be adjusted as needed. Generally, the connecting arm 1 and the guide plate 2 are perpendicular to each other.

[0030] The limit plate is clamped between the guide plate 2 and the connecting arm 1, and the connecting arm 1 abuts against the side of the bracket at the bottom end of the photovoltaic panel. The bracket can be connected to the support plate and the limit plate respectively. A side wall of the bracket at the bottom end, the support plate, and the limit plate can form a C-shaped accommodating cavity for the bottom end of the photovoltaic panel. The bottom end of the photovoltaic panel abuts against this side wall of the bracket. The support plate supports the photovoltaic panel, and the other side wall of the bracket at the bottom end can abut against the connecting arm 1. The surface of the guide plate 2 facing the limit plate can be provided with a buckle for clamping the limit plate. Pressing the guide plate 2 downward causes the limit plate to be located between the buckle and the guide plate 2.

[0031] During installation, place the connecting arm 1 against the side of the bracket at the bottom of the photovoltaic panel, press the guide plate 2 downward so that the limit plate is clamped between the guide plate 2 and the connecting arm 1, and the water guide and mud drainage clamp can be installed on the photovoltaic module. There is no need to install from the side of the photovoltaic module, and it can be installed directly in the gap of the built power station, saving time and effort. Generally, the water guide and mud drainage clamp of the present application is installed between two upper and lower adjacent photovoltaic panels, and the guide plate 2 is located at the top of the limit plate located in the upper position. The connecting arm 1 is inserted into the gap between its two adjacent brackets, and the two adjacent brackets limit the connecting arm 1 to prevent the guide plate 2 from detaching from the limit plate.

[0032] This application removes the conventional tail wing, and the thickness of the connecting arm 1 can be about 3mm. It can be installed together with the power station, and can also be installed later on an already built power station. It solves the problem that the existing water-guiding and mud-draining clamp has a wide tail wing and cannot be inserted into power stations with too narrow gaps. The connecting arm 1 of this application can be used in power stations with a gap of 3-5mm, while the water-guiding and mud-draining clamps on the market are mostly used in power stations with a component gap of 1.5cm.

[0033] In one embodiment, the connecting arm 1 is provided with beveled serrations 7 on the surface that abuts the bracket. These serrations increase friction between the connecting arm 1 and the bracket, strengthening the securement between the water-draining and mud-draining clamp and the photovoltaic module. During installation, only a portion of the beveled serrations 7 needs to be placed against the bracket. This allows for installation on photovoltaic modules of varying heights, such as 30 mm, 33 mm, and 35 mm, providing greater overall applicability and versatility.

[0034] In one embodiment, the surface of the deflector plate 2 near the connecting arm 1 has an envelope surface 3, and the stop plate is engaged between the envelope surface 3 and the connecting arm 1. The envelope surface can be the entire surface of the deflector plate 2 near the connecting arm 1, or a portion thereof. The envelope surface 3 can envelop the surface of the deflector plate 2 near the connecting arm 1 and abut against the top surface of the stop plate. Pressing the deflector plate 2 downward causes the stop plate to engage between the envelope surface 3 and the connecting arm 1.

[0035] In one embodiment, the envelope surface 3 conforms to the shape of the top surface of the stop plate. The envelope surface 3 envelops the top surface of the stop plate and the edge of the top surface of the stop plate away from the connecting arm 1, but the degree of envelopment should not interfere with the stop plate being secured between the guide plate 2 and the connecting arm 1, nor should it interfere with the contact between the envelope surface 3 and the top surface of the stop plate. If the top surface of the stop plate is rectangular, the envelope surface 3 is a rectangular shape that conforms to this rectangle; if the top surface of the stop plate is curved, the envelope surface 3 is a curved surface that conforms to this curve.

[0036] In one embodiment, a first groove 4 is provided on a surface of the guide plate 2 away from the envelope surface 3 .

[0037] In one embodiment, the first groove 4 is located at a middle position of the guide plate 2 away from the envelope surface 3 .

[0038] In one embodiment, the portion of the envelope surface 3 opposite to the first groove 4 is connected to the connecting arm 1 . The connection between the guide plate 2 and the connecting arm 1 is located on the envelope surface 3 and opposite to the first groove 4 .

[0039] In one embodiment, two second grooves 5 are provided on the surface of the guide plate 2 away from the envelope surface 3 , and the first groove 4 and the second groove 5 are connected.

[0040] The first groove 4 and the second groove 5 can guide muddy water on the photovoltaic panel.

[0041] In one embodiment, two second grooves 5 are respectively provided on both sides of the first groove 4 .

[0042] In one embodiment, two shells 6 are further included, which are respectively arranged on the outer sides of the two second grooves 5 relative to the first groove 4.

[0043] The first groove 4, the second groove 5 and the shell 6 together divert muddy water. The shell 6 can divert high water levels, and the first groove 4 and the second groove 5 can divert low water levels. The edges of the shell 6 can be sharp corners, which can temporarily destroy the surface tension of the water body and cause disturbance to the water body, which is conducive to the water diversion and mud removal function.

[0044] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
