Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, and in particular to a foldable photovoltaic panel that facilitates rainwater drainage. Background Technology

[0002] With the widespread application of photovoltaic power generation technology, the installation method of photovoltaic panels directly affects their power generation efficiency and ease of maintenance. Traditional photovoltaic panels are mostly fixed installations, which are difficult to adapt to different sunlight angles and are prone to water accumulation during heavy rain, leading to surface contamination or corrosion and affecting power generation efficiency. In addition, the transportation and storage of traditional photovoltaic panels occupy a large amount of space, which is not conducive to flexible deployment.

[0003] While some existing foldable photovoltaic (PV) panels (such as the Chinese utility model patent with publication number CN217590732U) have solved the problems of convenient transportation and installation, they still have shortcomings in terms of rainwater drainage. For example, the upper surface of the PV panel is lower than the upper surfaces of the movable and fixed frames. Although this can prevent the PV panels from colliding with each other when folded for shading, rainwater tends to accumulate in the area between the PV panel and the movable and fixed frames during rain. Because this area has a high moisture content and a slow evaporation rate, it easily seeps into the device from the installation position of the PV panel and the movable and fixed frames. More importantly, the device lacks a dedicated drainage system, making it difficult for the seeped water to drain. This not only prolongs the retention time of water inside the device but also easily causes corrosion of the PV panel. Furthermore, the water that seeps into the device is not easy to evaporate, thus its practicality is not very good. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a foldable photovoltaic panel that facilitates rainwater drainage, which can not only be conveniently folded and stored, but also effectively drain rainwater and has a buffer protection function, thus effectively improving the reliability and service life of the photovoltaic system.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A foldable photovoltaic panel that facilitates rainwater drainage includes a support base, a folding mounting frame disposed on the upper end of the support base, and a photovoltaic panel disposed within the folding mounting frame. A storage area is formed inside the folding mounting frame. A plurality of drainage holes are provided in the middle of the folding mounting frame. Guide slopes inclined towards the drainage holes are formed on both sides of the storage area. A lifting plate is fixedly connected to the lower end of the photovoltaic panel. A plurality of springs are fixedly disposed at the bottom of the storage area. The upper ends of the springs are connected to the lifting plate, so that the upper surface of the photovoltaic panel can move up and down relative to the upper surface of the folding mounting frame.

[0006] A further improvement of the present invention is that the folding mounting frame includes a fixed frame fixedly mounted on the support base and a movable frame hinged to the fixed frame via a rotating joint; the photovoltaic panel includes two independent panels respectively disposed within the fixed frame and the movable frame.

[0007] A further improvement of this utility model is that an operating handle is provided on the side wall of the movable frame.

[0008] A further improvement of this utility model is that the support base is provided with an extended support plate, the position of which corresponds to the support position of the movable frame of the adjacent photovoltaic panel when it is in the unfolded state.

[0009] A further improvement of this utility model is that shock-absorbing pads are provided on both sides of the upper surface of the photovoltaic panel.

[0010] A further improvement of this utility model is that the maximum distance between the lifting plate and the bottom of the storage area is greater than the distance between the upper surface of the folding installation frame and the upper surface of the shock-absorbing pad.

[0011] A further improvement of the present invention is that: the side wall of the folding mounting frame is provided with a mounting groove; a limiting plate is detachably provided in the mounting groove, and the lower end face of the limiting plate contacts and limits the upper end face of the lifting plate.

[0012] A further improvement of this utility model is that: the limiting plate has first threaded holes at both ends, and fastening bolts that cooperate with them are configured thereon.

[0013] A further improvement of this utility model is that: the side wall of the mounting groove is provided with a second threaded hole coaxial with the first threaded hole, and the fastening bolt simultaneously forms a threaded engagement with the first threaded hole and the second threaded hole.

[0014] A further improvement of this utility model is that the drainage holes are arranged symmetrically along the axis of the folding installation frame, and their cross-section is an inverted trapezoid, with the opening size gradually decreasing from top to bottom.

[0015] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows: 1. The foldable photovoltaic panel provided by this utility model uses a spring to push the lifting plate and the photovoltaic panel upward, so that the photovoltaic panel is higher than the folding installation frame. This makes it easier for rainwater falling on the photovoltaic panel to flow to the outside and prevents it from accumulating. Secondly, the rainwater entering the folding installation frame will be discharged to the outside through the combination of the guide slope and the drainage hole. After the rain, the ventilation of the drainage hole can facilitate the evaporation of internal moisture, which reduces the corrosion of the photovoltaic panel to a certain extent and improves the power generation efficiency.

[0016] 2. The drainage hole of this utility model adopts an inverted trapezoidal cross-section design to prevent debris from clogging and ensure smooth drainage over a long period of time.

[0017] 3. This utility model adopts a hinged design of a fixed frame and a movable frame, allowing the photovoltaic panels to be folded and stored, reducing space occupation and facilitating transportation and storage. The support base is equipped with an extended support plate, which can stably support adjacent photovoltaic panels in the unfolded state, eliminating the need for additional support structures and improving the convenience of installation.

[0018] 4. In this utility model, the photovoltaic panel is elastically supported by springs and lifting plates, which can buffer the impact when subjected to external forces (such as hail and strong winds) and reduce the risk of damage; the shock-absorbing pad further absorbs vibration, protects the surface of the photovoltaic panel, and extends its service life.

[0019] 5. In this utility model, the limiting plate can be detached and installed with bolts, which facilitates the adjustment of the lifting height of the photovoltaic panel and adapts to different installation environment requirements.

[0020] 6. The photovoltaic panel in this utility model adopts a split design, and a single damaged panel can be replaced individually, reducing maintenance costs. The design of the operating handle facilitates operation and improves the convenience of folding and unfolding.

[0021] 7. The foldable photovoltaic panel provided by this utility model has significant improvements in terms of structural optimization, drainage performance, impact resistance and ease of installation. It is suitable for various photovoltaic power generation scenarios, and is especially suitable for use in environments where water is easily accumulated and frequent handling is required.

Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: like Figures 1-2As shown, a foldable photovoltaic panel that facilitates rainwater drainage includes a support base 2, a folding mounting frame 1 disposed on the upper end of the support base 2, and a photovoltaic panel 3 disposed within the folding mounting frame 1. A storage area 5 is formed inside the folding mounting frame 1. Several drainage holes 8 (specifically, 3 holes) are provided in the middle of the folding mounting frame 1. Guide slopes 9 inclined towards the drainage holes 8 are formed on both sides of the storage area 5. A lifting plate 7 is fixedly connected to the lower end of the photovoltaic panel 3. Several springs 6 are fixedly provided at the bottom of the storage area 5 (specifically, 1 spring can be provided at each of the four corners of the storage area, for a total of 4 springs). The upper ends of the springs 6 are connected to the lifting plate 7, so that the upper surface of the photovoltaic panel 3 can move up and down relative to the upper surface of the folding mounting frame 1.

[0027] Furthermore, such as Figure 2 As shown, the inclined angle of the guide slope 9 is 5°~15°, and the surface is coated with a hydrophobic coating. The spring 6 is a stainless steel helical spring, and its extension stroke is greater than half the thickness of the photovoltaic panel 3. A sealing ring is provided between the lifting plate 7 and the inner wall of the storage area 5 to prevent rainwater from seeping into the spring 6 area. The folding mounting frame 1 is made of aluminum alloy, and the surface is anodized.

[0028] Furthermore, such as Figure 1 As shown, the folding mounting frame 1 includes a fixed frame 1-1 fixedly mounted on the support base 2 and a movable frame 1-2 hinged to the fixed frame 1-1 via a rotating joint 1-3; the photovoltaic panel 3 includes two independent panels respectively disposed within the fixed frame 1-1 and the movable frame 1-2.

[0029] Furthermore, such as Figure 1 As shown, an operating handle 4 is provided on the side wall of the active frame 1-2.

[0030] Furthermore, such as Figure 1 As shown, the support base 2 is provided with an extension support plate 2-1, the position of which corresponds to the support position of the movable frame 1-2 of the adjacent photovoltaic panel when it is in the unfolded state.

[0031] Furthermore, such as Figure 4 , Figure 5 As shown, shock-absorbing pads 12 are provided on both sides of the upper surface of the photovoltaic panel 3.

[0032] Furthermore, the maximum distance between the lifting plate 7 and the bottom of the storage area 5 is greater than the distance between the upper surface of the folding mounting frame 1 and the upper surface of the shock-absorbing pad 12. This ensures that when the folding mounting frame 1 is in the folded state, the storage area 5 has sufficient space to store the lifting plate 7, the photovoltaic panel 3, and the shock-absorbing pad 12.

[0033] Furthermore, such as Figure 6 As shown, the side wall of the folding mounting frame 1 is provided with a mounting groove 10; a limiting plate 11 is detachably provided in the mounting groove 10, and the lower end face of the limiting plate 11 contacts and limits the upper end face of the lifting plate 7.

[0034] Furthermore, such as Figure 3 , Figure 5 As shown, the limiting plate 11 has first threaded holes at both ends, and fastening bolts that cooperate with them are provided.

[0035] Furthermore, such as Figure 6 As shown, the side wall of the mounting groove 10 is provided with a second threaded hole coaxial with the first threaded hole, and the fastening bolt forms a threaded engagement with both the first threaded hole and the second threaded hole.

[0036] Specifically, the lifting plate 7 is placed in the mounting groove 10, and the bolts are screwed into the first threaded hole of the lifting plate 7 and then into the second threaded hole, thereby fixing the lifting plate 7 in the mounting groove 10 so that it no longer moves.

[0037] Furthermore, such as Figure 2 As shown, the drainage holes 8 are arranged symmetrically along the central axis of the folding mounting frame 1, and their cross-section is an inverted trapezoid, with the opening size gradually decreasing from top to bottom.

[0038] Specifically, the staff grasps the operating handle 4 to rotate the movable frame 1-2 until it closes on the fixed frame 1-1. At this time, the shock-absorbing pads 12 on the two photovoltaic panels 3 are in contact with each other to prevent the photovoltaic panels 3 from colliding.

[0039] When the operator grasps the operating handle 4 to unfold the movable frame 1-2 and the fixed frame 1-1, the spring 6 extends, causing the lifting plate 7 to move upward, which in turn moves the photovoltaic panel 3, making the end face of the photovoltaic panel 3 higher than the end faces of the fixed frame 1-1 and the movable frame 1-2. When cleaning and maintenance are required, the fixed frame 1-1 and the movable frame 1-2 are covered, and the shock-absorbing pads 12 of the two photovoltaic panels 3 are pressed together, pressing the photovoltaic panel 3 into the storage area 5. At the same time, the lifting plate 7 is compressed and moves, and the lifting plate 7 compresses the spring 6, causing the spring 6 to... In a compressed state; the folding mounting frame 1 has a drainage hole 8 in the middle. During rain, most of the water flows from the end face of the photovoltaic panel 3 to the outside of the folding mounting frame 1, and a small portion of the rainwater enters the folding mounting frame 1 and is discharged to the outside through the drainage hole 8. The storage area 5 has a guide slope 9 in the middle. The rainwater flows quickly along the guide slope 9 to the drainage hole 8 for discharge. After the rain ends, the water in the folding mounting frame 1 evaporates quickly under the ventilation effect of the drainage hole 8, and can also cool down the photovoltaic panel 3.

[0040] In summary, this utility model provides a foldable photovoltaic panel that facilitates rainwater drainage. During use, rainwater falls onto the photovoltaic panel 3 and then slides off to the outside of the folding mounting frame 1. When the rainfall is heavy, a small portion of the rainwater will seep into the folding mounting frame 1 from between the lifting plate 7 and the folding mounting frame 1, and then flow along the guide slope 9 to the drain hole 8 for discharge to the outside. When it is necessary to store the photovoltaic panel 3, the operator grasps the operating handle 4 on the side wall of the movable frame 1-2, causing the movable frame 1-2 to rotate until it is closed on the fixed frame 1-1. At this time, the shock-absorbing pads 12 on the two photovoltaic panels 3 are in contact with each other to prevent the photovoltaic panels 3 from colliding. During this process, the lifting plate 7 will move accordingly and compress the spring 6, keeping the spring 6 in a compressed state.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
