Description

Technical Field

[0001] This utility model relates to photovoltaic support technology, and in particular to a water guiding device for a distributed photovoltaic support. Background Technology

[0002] Distributed photovoltaic (PV) power plants, as a clean energy solution, have been widely used on the rooftops of various buildings and in open areas. During the long-term operation of a PV power plant, the photovoltaic panels are usually installed at a certain angle to maximize the reception of solar radiation. However, in rainy or snowy weather, rainwater or melted snow washes away dust, bird droppings, and other debris from the surface of the photovoltaic panels, which then flow towards the lower edge of the panels.

[0003] Because of the inherent height of the photovoltaic panel frame, water carrying dirt easily accumulates on the lower edges and corners. After the water evaporates, the dust and sludge solidify, forming a noticeable "dirt band." This dirt band obstructs the solar cells at the bottom of the panel, directly causing a loss of power generation in that area. More seriously, the obstructed cells will overheat due to their inability to function properly, creating a "hot spot effect." Over time, this accelerates the aging of the cells and can even cause permanent damage, severely impacting the overall power generation efficiency and lifespan of the photovoltaic power station.

[0004] To address this issue, some simple water-guiding devices have emerged in the existing technology, such as plastic or metal water-guiding clips that directly clip onto the frame of the photovoltaic panel. While these clips can guide water drainage to some extent, their structure and installation methods have significant shortcomings. First, their drainage effect is usually limited to a single point or a small area, failing to effectively and comprehensively drain water from the entire edge of the photovoltaic panel, especially the corners most prone to water accumulation, resulting in dirt still accumulating between the clips or in the corners. Second, these water-guiding clips are mostly rigid or elastic snap-fit ​​structures with fixed dimensions, making them poorly adaptable to the dimensional tolerances of photovoltaic panels from different manufacturers and batches. If too tight, they may damage the anodized layer of the frame; if too loose, they are prone to loosening and falling off under the influence of wind, sun, and thermal expansion and contraction, resulting in low reliability.

[0005] Therefore, this utility model proposes a distributed photovoltaic support water guiding device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of poor drainage effect of existing distributed photovoltaic support water guiding devices, especially the difficulty in handling water accumulation at the edges and corners of photovoltaic panels, fixed installation position and poor versatility, and the use of rigid fixing, which is prone to damage to photovoltaic panels due to excessive tightness or loosening due to thermal expansion and contraction, resulting in low reliability, this utility model aims to provide a distributed photovoltaic support water guiding device with improved structure that can effectively solve the above problems.

[0007] This utility model provides a water guiding device for a distributed photovoltaic support, including: a fixed frame, a water guiding pipe; as well as a water guiding clamp, a pulley, a fixed plate, a spring plate, and a limiting plate with an adjustment knob.

[0008] The top side of the fixing frame is provided with a guide rail, and the water guide clamp is slidably mounted on the guide rail by a pulley on its inner side, and the water guide clamp is used to clamp the water guide pipe.

[0009] Furthermore, the fixing plate is connected to the fixing frame, the spring plate is slidably disposed on the inner side of the fixing plate, and the adjusting knob is combined with the spring plate by means of a threaded connection.

[0010] Preferably, the distributed photovoltaic support water guiding device further includes a rotating shaft and a fixing bolt. The pulley is rotatably mounted inside the water guiding clamp via the rotating shaft, and the fixing bolt is threadedly connected to the rotating shaft to lock the pulley.

[0011] Preferably, the distributed photovoltaic support water guiding device further includes a corner water guiding connector, which is disposed on the inner side of the water guiding pipe.

[0012] Furthermore, the water guide pipe is a pipe body with an open groove, and the corner water guide joint is located at the end of the water guide pipe.

[0013] Preferably, the distributed photovoltaic support water guiding device further includes a fixing screw, and the fixing plate is fixedly connected to the fixing frame by the fixing screw.

[0014] Preferably, the spring plate is provided with a threaded hole that mates with the adjustment knob.

[0015] Preferably, the guide rail is a groove extending along the length direction of the top side of the fixing frame.

[0016] Preferably, the mounting bracket has a central opening and an arm extending outward from the central opening.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of water accumulation at the edges and corners of photovoltaic panels being difficult to effectively collect and drain in the prior art by setting a corner water guide joint on the inside of the water guide pipe. It achieves the effect of thorough drainage of water accumulation on the surface of photovoltaic panels without dead corners, avoids long-term retention of water stains and dirt, thereby ensuring the maximum light-receiving area of ​​the photovoltaic panel and improving work efficiency.

[0018] 2. This utility model solves the problems of fixed position, inconvenient installation and difficulty in adapting to photovoltaic panels of different size tolerances in existing water guiding devices by setting a guide rail on the top side of the fixed frame and a pulley that slides with the guide rail. It achieves the technical effect of flexible and adjustable installation position and convenient and fast installation process, which greatly enhances the versatility and applicability of the device.

[0019] 3. This utility model solves the problem that traditional rigid fixing methods may damage photovoltaic panels due to excessive tightness or loosen due to thermal expansion and contraction by setting a sliding spring plate and using an adjustment knob threaded to the spring plate to adjust the contact force. It achieves the technical effect of stable and reliable installation, controllable contact force and elastic buffer, which can not only ensure the long-term stability of the device under various working conditions, but also effectively protect the photovoltaic panels from damage.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Please refer to Figures 1 to 6 This utility model provides a water guiding device for a distributed photovoltaic support, which aims to solve the problem of reduced power generation efficiency caused by water and dust accumulation at the edges and corners of photovoltaic panels in the prior art.

[0024] like Figure 1 As shown, this distributed photovoltaic (PV) bracket water guiding device is applied to a PV panel 1, including a fixing frame 2 installed on the four outer sides of the PV panel 1, and a water guiding pipe 4 supported by the fixing frame 2. The device also includes a water guiding clamp 3, pulleys 8, a limiting plate 6 with an adjustment knob 11, a fixing plate 12, and a spring plate 13. The overall structure, through the combination of multiple components, securely mounts the device to the edge of the PV panel 1, and guides the accumulated water on the surface of the PV panel 1 into the water guiding pipe 4 for collection and drainage. Please refer to Figures 1 to 6 The top side of the fixing frame 2 is provided with a guide rail 5 extending along its length, and the guide rail 5 has a groove structure; the water guide clamp 3 is used to clamp the water guide pipe 4, and the pulley 8 is rotatably installed on the inner side of the water guide clamp 3 through the rotating shaft 10. The water guide clamp 3 is also provided with a fixing bolt 9 that is threadedly connected to the rotating shaft 10; during assembly, the water guide clamp 3 with the pulley 8 is slidably connected to the guide rail 5 of the fixing frame 2, and the water guide clamp 3 can be firmly locked in any position on the guide rail 5 by tightening the fixing bolt 9.

[0025] The fixing plate 12 is fixedly connected to the fixing frame 2 by the fixing screw 14; please refer to Figure 5 The spring plate 13 is an elastic plate-shaped structure with a threaded hole that mates with the adjusting knob 11. The spring plate 13 is slidably disposed inside the fixing plate 12, with one end abutting against the side of the photovoltaic panel 1. The fixing frame 2 is provided with a limiting plate 6 on the rear side with the adjusting knob 11. The adjusting knob 11 passes through the limiting plate 6 and is threadedly connected to the threaded hole on the spring plate 13. By rotating the adjusting knob 11, the spring plate 13 can be driven to move back and forth inside the fixing plate 12, thereby changing the contact force between the spring plate 13 and the side of the photovoltaic panel 1, providing a buffer for the device and ensuring the stability of the installation.

[0026] As one specific implementation method, please refer to Figure 2 and Figure 6The structure of the water pipe 4 is a pipe with an open groove to facilitate the collection of water flow from the surface of the photovoltaic panel 1; the inner side of the water pipe 4 is also provided with a corner water connector 7, which is specially set at the end of the water pipe 4 or near the corner, to specifically collect the water that is difficult to drain from the edge and corner of the photovoltaic panel 1 and guide it into the main channel of the water pipe 4.

[0027] Please refer to Figure 3 and Figure 4 The fixed frame 2 has a central opening and an arm-shaped structure extending outward from the central opening; the pulley 8 is rotatably mounted on the inner side of the water guide clamp 3 via the rotating shaft 10, and the water guide clamp 3 is provided with a fixing bolt 9 that is threadedly connected to the rotating shaft 10. After the position of the water guide clamp 3 is adjusted, the pulley 8 can be locked by tightening the fixing bolt 9, thereby achieving a stable positioning of the water guide clamp 3 on the guide rail 5.

[0028] Please refer to Figure 4 and Figure 5 The fixing plate 12 is fixedly connected to the fixing frame 2 by the fixing screw 14, providing reliable structural support for the entire device; the spring plate 13 has a threaded hole that matches the adjusting knob 11, and the threaded connection between the spring plate 13 and the adjusting knob 11 is achieved through the threaded hole. This structure allows the extension position and tightness of the spring plate 13 to be precisely adjusted when the adjusting knob 11 is rotated.

[0029] Working principle: When this novel distributed photovoltaic support water guiding device is in operation, the fixing frame 2 is first installed on the outer edge of the photovoltaic panel 1. The water guiding clamp 3, which is equipped with pulley 8, is slidably installed to the predetermined position through the guide rail 5 on the fixing frame 2. The water guiding clamp 3 clamps and fixes the water guiding pipe 4 inside. After the position is determined, the fixing bolt 9 that is threaded with the rotating shaft 10 is tightened, so that the pulley 8 is locked and the water guiding clamp 3 is firmly fixed on the guide rail 5. Then, the operator rotates the adjustment knob 11 on the back of the limiting plate 6. The rotation of the adjustment knob 11 is converted into the linear sliding of the spring plate 13 inside the fixing plate 12 through the thread transmission between the adjustment knob 11 and the threaded hole on the spring plate 13. This allows for precise adjustment of the contact pressure applied by the spring plate 13 to the side wall of the photovoltaic panel 1, thereby achieving stable installation and elastic buffering of the device.

[0030] When it rains or snow melts, water on the surface of the photovoltaic panel 1 flows down the panel to the lower edge. The water is collected in the opening groove of the water pipe 4. In particular, water that accumulates at the edges and corners of the photovoltaic panel 1 is effectively captured by the corner water inlet 7 inside the water pipe 4 and directed into the main channel. The collected water is guided and discharged through the entire through-flow water pipe 4 system, thereby keeping the surface of the photovoltaic panel 1 clean and avoiding the impact of local water and dust accumulation on its normal operation.
