Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a slope photovoltaic module water guiding and drainage device. Background Technology

[0002] When photovoltaic (PV) power generation systems are constructed on slopes along highways, railways, and airports, the PV modules will create a runoff effect on rainwater. Rainwater that would otherwise fall scattered across the slope will converge on the surface of the PV modules and then fall concentratedly from the lower edge of the modules onto the localized slope surface. This can cause erosion in certain areas, leading to soil loss and affecting the slope's stability and safety. The consequences are particularly severe in collapsible loess areas. Furthermore, because the lower edge of the PV modules has a raised area, water will accumulate there after rain. If this water cannot be drained promptly, it can evaporate and form muddy stains, obstructing the PV cells, reducing power generation efficiency, and even causing hot spots that damage the modules.

[0023] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the technical problem that existing slope photovoltaic module drainage devices cannot effectively divert water trapped at the raised edges of the modules, this application proposes a slope photovoltaic module drainage device.

[0026] Reference Figure 1 A slope photovoltaic module water drainage device is disclosed. The water drainage device is connected to the photovoltaic module, which includes a photovoltaic panel 1 and a photovoltaic support frame. The photovoltaic panel 1 is connected to the photovoltaic support frame. The water drainage device includes:

[0027] Drainage trough 2 is provided along the length of the lower edge of photovoltaic panel 1;

[0028] Water guide clip 3 is clamped at the lower edge of the photovoltaic panel 1, and the water guide clip 3 can guide the water accumulated at the lower edge of the photovoltaic module to the drainage channel 2.

[0029] Pull rod 4, one end of which is connected to water guide clamp 3, and the other end of which is connected to one side wall of drainage trough 2; and,

[0030] Support 5 is located below photovoltaic panel 1 and is connected to the other side wall of photovoltaic bracket, photovoltaic panel 1 and drainage trough 2.

[0031] In this embodiment, when rainwater falls on the photovoltaic module, most of the rainwater flows along the surface of the photovoltaic panel 1 to the lower edge and falls directly into the drainage trough 2, which is set along the length of the lower edge of the photovoltaic panel 1. Water accumulated at the raised frame at the lower edge of the photovoltaic panel 1 is guided into the drainage trough 2 through the guiding structure of the water guide clamp 3 itself. During this process, one end of the tension rod 4 is connected to the water guide clamp 3, and the other end is connected to one side wall of the drainage trough 2. Through the pulling action of the tension rod 4, the water guide clamp 3 is stably clamped at the raised frame at the lower edge of the photovoltaic panel 1, ensuring the normal functioning of the water guide clamp 3 and enhancing the stability of the drainage trough 2. The support member 5 is located below the photovoltaic panel 1 and is connected to the photovoltaic bracket, the photovoltaic panel 1, and the other side wall of the drainage trough 2. It provides additional support for the photovoltaic panel 1 and further reinforces the drainage trough 2, making the entire water guiding and drainage device a stable whole, thereby efficiently completing the water guiding and drainage work of the photovoltaic module.

[0032] The above embodiment proposes a slope photovoltaic module water guiding and drainage device. By setting a drainage channel 2 along the length of the lower edge of the photovoltaic panel 1, rainwater flowing from the surface of the photovoltaic module is collected and concentrated, preventing rainwater from dripping directly from the lower edge of the photovoltaic panel 1 onto the local ground of the slope and causing an erosion effect. At the same time, the water guiding clip 3 guides the water accumulated at the raised edge of the lower edge of the photovoltaic panel 1 into the drainage channel 2, reducing the evaporation of water and the formation of mud and dirt that obstructs the photovoltaic panel 1, thereby improving power generation efficiency. In addition, the support member 5 is connected to the photovoltaic bracket, the photovoltaic panel 1 and the drainage channel 2, enhancing the overall structural stability. This effectively solves the technical problem that existing photovoltaic power generation systems are prone to causing slope soil erosion, ensuring the stability and safety of the slope.

[0033] As an optional implementation, the sidewall of the drainage trough 2 opposite to the photovoltaic panel 1 has a first vertical wall section 6, a first arc-shaped section 7, and a second vertical wall section 8. The first vertical wall section 6, the first arc-shaped section 7, and the second vertical wall section 8 are arranged sequentially from top to bottom, and the second vertical wall section 8 is connected to one end of the tension rod 4. The top height of the first vertical wall section 6 is higher than the height of the lower edge protruding frame of the photovoltaic panel 1.

[0034] It should be noted that the top height of the first vertical wall section 6 is higher than the height of the lower edge protruding frame of the photovoltaic panel 1 because the water flowing from the surface of the photovoltaic panel 1, after converging at the angle to the lower edge frame, will drip downwards in a parabolic trajectory due to gravity, rather than falling vertically into the straight wall area of ​​the drainage ditch 2 directly below. At this time, the first vertical wall section 6 is located exactly in front of the water droplet, becoming the first barrier to intercept the water flow and prevent the water from flowing over the drainage ditch 2 and onto the slope.

[0035] Additionally, it should be noted that the second vertical wall section 8 is mainly used for connection with the tension rod 4.

[0036] In this embodiment, rainwater dripping from the lower edge of the photovoltaic panel 1 first impacts the first vertical wall section 6, and then flows downwards along the first vertical wall section 6 to the first arc-shaped section 7. The presence of the first arc-shaped section 7 allows the water flow to smoothly change direction, preventing the water flow from directly impacting the bottom of the drainage trough 2 and splashing up. Next, after passing through the first arc-shaped section 7, the water flow continues to the second vertical wall section 8, and finally flows into the drainage trough 2, completing the drainage work.

[0037] As an optional implementation, the sidewall of the drainage trough 2 opposite to the photovoltaic panel 1 also has a straight section 9, a second arc-shaped section 10 and a third vertical wall section 11, which are arranged sequentially from top to bottom. The straight section 9 is arranged at an inclined angle to the vertical plane and is connected to the second vertical wall section 8.

[0038] It should be noted that the sidewall of the drainage trough 2 opposite to the photovoltaic panel 1 is provided with a straight section 9, a second arc-shaped section 10, and a third vertical wall section 11. The straight section 9 forms an angle with the vertical plane at an inclined angle, which can guide the water flow to accelerate along the inclined surface and flow into the structure below, expanding the water collection range. The second arc-shaped section 10 reduces the water flow impact resistance through a smooth transition, improving drainage efficiency. The third vertical wall section 11, together with the straight section 9 and the second arc-shaped section 10, forms a composite support structure. When the water flow impacts or the outer side is pulled by the tension rod 4, the three are rigidly connected to distribute the load. In particular, the third vertical wall section 11, as the end support, can effectively resist the deformation trend of the outer side of the drainage trough 2. At the same time, the outer expansion space formed by the combination of the inclined straight section 9 and the arc-shaped section increases the cross-sectional area of ​​the trough, thereby increasing the water collection capacity. Ultimately, through structural optimization, the dual improvement of deformation resistance and water collection capacity is achieved simultaneously.

[0039] As an optional implementation, the water guide clamp 3 is a stainless steel siphon-type water guide clamp 3.

[0040] It should be noted that the stainless steel siphon-type water guide clamp 3 is existing technology. It usually adopts a U-shaped or C-shaped clamping structure and has a guide groove or siphon channel on the inside. It uses the siphon effect to absorb the water accumulated at the raised frame at the lower edge of the photovoltaic panel 1 and guide it to the drainage groove 2.

[0041] Specifically, when water forms a liquid column at the edge, the internal channel of the water guide clamp 3 utilizes the siphon effect created by the difference in liquid level to actively draw the water into the tank, achieving efficient water diversion without additional power. Simultaneously, its clamping end is fixed to the edge via an elastic structure or bolts, ensuring a stable connection between the clamping clamp 3 and the pull rod 4 in the drainage tank 2. Furthermore, the high strength and corrosion resistance of the stainless steel material allow for long-term stable operation in complex outdoor environments, preventing clamping failure or deterioration of the diversion function due to rust.

[0042] As an alternative implementation, the tension rod 4 is set at an angle to the horizontal plane.

[0043] It should be noted that the inclined tension rod 4 can convert the vertical water load and horizontal tensile stress transmitted by the water guide clamp 3 into axial tensile force along the rod body, thus avoiding deformation of the connection part 13 caused by stress concentration.

[0044] In addition, the tilt angle of the tension rod 4 can be set to match the installation tilt angle of the photovoltaic panel 1, so that the pulling direction of the tension rod 4 is consistent with the force direction of the outward expansion side of the drainage trough 2, thereby enhancing the support rigidity of the side wall of the drainage trough 2. For example, when the water flow impacts the outward expansion side of the drainage trough 2, the tilted tension rod 4 can enhance the water flow impact capacity of the device by pulling obliquely.

[0045] As an alternative implementation, the support member 5 is arranged parallel to the photovoltaic panel 1, and the support member 5 and the photovoltaic panel 1 are connected by purlins 12.

[0046] It should be noted that when the support member 5 is arranged parallel to the photovoltaic panel 1 and connected by the purlin 12, a stable double-layer support structure can be formed: the parallel arrangement makes the force direction of the support member 5 and the photovoltaic panel 1 consistent, and the weight of the photovoltaic panel 1 and the external load are evenly transferred to the support member 5 through the purlin 12, avoiding local stress concentration.

[0047] As an optional implementation, the support member 5 is made of U-shaped steel, and the side wall adjacent to the drainage channel 2 and the support member 5 is provided with a connecting part 13, and the connecting part 13 is connected to the upper surface of the support member 5. The lower surface of the support member 5 is connected to the side wall of the drainage channel 2 through the connecting diagonal rod 14.

[0048] It should be noted that when the support member 5 is made of U-shaped steel, its channel structure can provide strong bending stiffness. The connection part 13 adjacent to the side wall of the drainage trough 2 is fixed through the upper surface to form a stable top support. At the same time, the lower surface of the support member 5 is connected to the side wall of the drainage trough 2 through the connecting diagonal rod 14 to form a triangular support structure, which effectively enhances the overall stability.

[0049] As an alternative implementation, the photovoltaic panel 1 is connected to the purlin 12, the purlin 12 to the support member 5, the connecting part 13 to the support member 5, the connecting diagonal rod 14 to the support member 5, and the tension rod 4 to the side wall of the drainage channel 2 by bolted connectors 15.

[0050] It should be noted that when using bolted connectors 15 to connect the various components, the detachability and structural stability of the bolted connection can be utilized to achieve convenient installation and maintenance of the device.

[0051] As an optional implementation, there are several photovoltaic panels 1, and several photovoltaic panels 1 are spliced ​​together in sequence. Each photovoltaic panel 1 is clamped with a water guide clip 3, and each water guide clip 3 is connected to a tension rod 4.

[0052] It should be noted that when several photovoltaic panels 1 are spliced ​​together in sequence, each photovoltaic panel 1 has a water-guiding clip 3 clamped at its lower edge and connected to a tension rod 4, forming a distributed water-guiding system covering the entire photovoltaic module. On the one hand, each water-guiding clip 3 independently guides the water accumulated on the edge of the corresponding photovoltaic panel 1, preventing water from stagnating between the panels when multiple panels are spliced ​​together, and ensuring that the water accumulated on each panel can be quickly guided into the drainage channel 2 through the siphon effect, solving the problem of guiding water accumulation at the edges of large-area modules; on the other hand, the distributed connection between the tension rod 4 and the water-guiding clip 3 ensures that the outer side of the drainage channel 2 is subjected to uniform tensile stress, avoiding excessive local stress that could lead to deformation.

[0053] Specifically, for example, each photovoltaic panel 1 is 1.1 meters long. In the long strip-shaped module spliced ​​with multiple panels, a water guide clamp 3 and a tension rod 4 are set every 1.1 meters to form equally spaced support points. This ensures the structural stability of the drainage channel 2 along its length and enables precise drainage of water accumulated on the edge of each photovoltaic panel 1. This makes the device suitable for photovoltaic module arrays of different sizes and improves the overall water guiding and drainage efficiency of the device.

[0054] As an optional implementation, the number of support members 5 is several, and the several support members 5 are evenly arranged along the splicing extension direction of the photovoltaic panel 1.

[0055] It should be noted that when several support members 5 are evenly arranged along the splicing extension direction of the photovoltaic panel 1, a continuous support system along the length of the module can be formed. The evenly arranged support members 5 are connected to the photovoltaic panel 1 through purlins 12, distributing the weight of the photovoltaic module and external loads to multiple support points, avoiding overload on individual support members 5; at the same time, each support member 5 forms an independent triangular support unit with the connection part 13 and the connecting diagonal rod 14 of the side wall of the drainage channel 2, and each unit works together along the splicing direction to enhance the overall bending and torsional deformation resistance of the drainage channel 2.

[0056] Specifically, for example, in a photovoltaic module array, the support members 5 set at certain intervals (such as 4 meters) can effectively resist the downward trend of the drainage channel 2 due to its own length, ensuring that the drainage channel 2 remains straight along the extension direction, thereby ensuring smooth water discharge.
