Description

Technical Field

[0001] This utility model relates to the field of Topcon component technology, and in particular to a photovoltaic railing for balconies based on Topcon components. Background Technology

[0002] Photovoltaic modules have broad application prospects in the field of BIPV. Their high efficiency, reliability and adaptability enable BIPV systems to operate stably for a long time, while improving the aesthetics of buildings.

[0003] In the prior art, such as the Chinese utility model patent with announcement number CN218758418U, a BIPV balcony photovoltaic railing based on HJT batteries is disclosed. In this device, the photovoltaic module can rotate between two columns, which makes it easy to adjust the orientation of the light-receiving surface of the photovoltaic module. After cleaning the photovoltaic module, the light-receiving surface of the photovoltaic module can be turned outward to improve the photovoltaic power generation efficiency.

[0004] However, in the aforementioned photovoltaic railing, the photovoltaic modules are fixedly connected. When one photovoltaic module rotates, it will inevitably cause the other photovoltaic modules to rotate synchronously, making it difficult to adjust the orientation of the light-receiving surface when rotating multiple photovoltaic modules. Moreover, the locking unit mainly includes locking bolts, bushings, and locking nuts. The locking bolts are exposed, and since the photovoltaic railing is used on a balcony, the locking bolts are very susceptible to moisture and corrosion, affecting the normal use of the locking unit.

[0005] Therefore, it is necessary to improve the existing photovoltaic railings for balconies. Utility Model Content

[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a photovoltaic railing for balconies based on Topcon components that is easy to operate, labor-saving, and ensures normal use.

[0007] To achieve the above-mentioned technical effects, the technical solution of this utility model is: a photovoltaic railing for balconies based on Topcon modules, comprising:

[0008] A fixing frame, the fixing frame including a horizontal axis extending in a horizontal direction and uprights disposed at both ends of the horizontal axis and extending in a vertical direction;

[0009] A photovoltaic module, wherein the photovoltaic modules are distributed along the horizontal axis and rotatably connected to the horizontal axis, and the rotation axis of the photovoltaic modules coincides with the axis of the horizontal axis;

[0010] A locking component is provided, which corresponds one-to-one with the photovoltaic module and is disposed between the photovoltaic module and the fixing frame. The locking component is used to lock the photovoltaic module in the power generation position and the cleaning position. In the power generation position, the light-receiving surface of the photovoltaic module faces outward, and in the cleaning position, the light-receiving surface of the photovoltaic module faces inward.

[0011] The photovoltaic module has two lock holes on its two side walls facing each other on the outer periphery. The lock holes are through holes. The locking component includes a tube and a pin. The tube is set on the fixing frame. One of the lock holes is engaged with the tube through the pin.

[0012] Preferably, in order to facilitate operation and prevent the pin from dislodging from the insertion tube, the fixing frame includes a base fixed between the bottoms of the columns, and the insertion tube is disposed on the base and extends in the vertical direction.

[0013] Preferably, in order to facilitate the stable rotation of the photovoltaic module and to facilitate locking the photovoltaic module in the power generation and cleaning positions, the photovoltaic module includes a photovoltaic cell and four frame profiles surrounding the photovoltaic cell and connected end to end in sequence. Among the four frame profiles, two are rotating profiles that are sealed and sleeved outside the horizontal axis and extend along an axis perpendicular to the horizontal axis, and the remaining two are positioning profiles that extend along an axis parallel to the horizontal axis. The locking hole is provided on the positioning profile.

[0014] Preferably, in order to enhance the waterproof performance of the photovoltaic module and ensure the stable rotation of the photovoltaic module, a rotating sleeve is sealed and fixedly inserted on the rotating profile. The rotating sleeve is sealed and fitted outside the horizontal axis and extends in a direction perpendicular to the length direction of the rotating profile.

[0015] Preferably, in order to further enhance the waterproof performance of the photovoltaic module, a positioning sleeve is sealed and fixedly inserted on the positioning profile, and the inner cavity of the positioning sleeve is the lock hole.

[0016] Preferably, to prevent the pin from disengaging from the insertion tube, the pin includes a thin rod and a locking bar connected in sequence and perpendicular in length direction. The axial direction of the thin rod is consistent with the axial direction of the pin. The projection of the thin rod along its own axial direction is located within the projection of the locking bar along the axial direction of the thin rod. A cover plate is provided at the top of the insertion tube. A strip-shaped hole is provided on the cover plate for the locking bar to pass through. An elastic element is provided inside the insertion tube. The elastic element is used to lock the locking bar to the bottom of the cover plate.

[0017] Preferably, in order to further prevent the pin from dislodging from the insertion tube, the bottom surface of the cover plate is provided with a recess to accommodate the locking bar.

[0018] Preferably, in order to facilitate the rotation of the pin and adjust the position of the locking bar relative to the strip hole, the pin further includes a rotating shaft fixed to the end of the thin rod away from the locking bar, and the locking hole is a cylinder with an inner diameter consistent with the rotating shaft.

[0019] Preferably, to facilitate operation of the pin, a handle is fixed to the end of the pin away from the insertion tube.

[0020] In summary, compared with existing technologies, the photovoltaic railing for balconies based on Topcon components of this utility model features relatively independent photovoltaic components, allowing for individual cleaning of each component and reducing operational effort. The pin passes through one of the lock holes and engages with the insertion tube to lock the position of the photovoltaic component, thus overcoming the disadvantage of bolts being prone to corrosion and ensuring the normal use of the locking component.

[0032] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0033] First Embodiment

[0034] like Figures 1-5 As shown, the first embodiment of the photovoltaic railing for balconies based on Topcon components of this utility model includes:

[0035] The fixing frame 1 includes a horizontal axis 11 extending in the horizontal direction and vertical columns 12 disposed at both ends of the horizontal axis 11 and extending in the vertical direction.

[0036] Photovoltaic module 2 is distributed along the horizontal axis 11 and is rotatably connected to the horizontal axis 11. The rotation axis of photovoltaic module 2 coincides with the axis of horizontal axis 11.

[0037] Locking component 3 corresponds one-to-one with photovoltaic module 2 and is set between photovoltaic module 2 and fixing frame 1. Locking component 3 is used to lock photovoltaic module 2 in power generation position and cleaning position. In power generation position, the light-receiving surface of photovoltaic module 2 faces outward, and in cleaning position, the light-receiving surface of photovoltaic module 2 faces inward.

[0038] The photovoltaic module 2 has two lock holes 232 on the two side walls facing each other on the outer periphery. The lock holes 232 are through holes. The locking component 3 includes a tube 4 and a pin 5. The tube 4 is set on the fixing frame 1. One of the lock holes 232 is engaged with the tube 4 through the pin 5.

[0039] In this photovoltaic railing for the balcony, the uprights 12 of the fixing frame 1 are fixed to the balcony. Two photovoltaic modules 2 are provided, spaced apart along the distribution direction of the uprights 12. There are three photovoltaic modules 2 (of course, the number of photovoltaic modules 2 can also be more depending on the size of the balcony and the photovoltaic modules 2). The photovoltaic modules 2 rotate on the horizontal axis 11, and four convex rings 111 are evenly distributed on the horizontal axis 11. The spacing between adjacent convex rings 111 is consistent with the width of the photovoltaic module 2, which prevents the photovoltaic modules 2 from shifting along the axial direction of the horizontal axis 11 and ensures that each photovoltaic module 2 is relatively independent. In this way, the rotation of one photovoltaic module 2 will not affect the other photovoltaic modules 2, making it convenient to operate any photovoltaic module 2 individually, thereby facilitating the adjustment of the light-receiving surface orientation of each photovoltaic module 2, and making the operation convenient.

[0040] The number of locking components 3 is equal to the number of photovoltaic modules 2, and they correspond one-to-one. Under normal use, the locking components 3 lock the photovoltaic modules 2 in the power generation position. In the power generation position, the light-receiving surface of the photovoltaic modules 2 faces outward, which facilitates the photovoltaic power generation of the photovoltaic modules 2 to supply power to the electrical facilities inside the building. After long-term use, the locking components 3 are removed from the photovoltaic modules 2, and the photovoltaic modules 2 are rotated to the cleaning position. Then, the locking components 3 are used to lock the photovoltaic modules 2 in the cleaning position, so that the light-receiving surface of the photovoltaic modules 2 faces inward, which facilitates the cleaning of the light-receiving surface of the photovoltaic modules 2. After cleaning, the photovoltaic modules 2 are rotated back to the power generation position and locked, thereby ensuring the photovoltaic power generation efficiency of the photovoltaic modules 2.

[0041] In the locking component 3, after the pin 5 passes through the locking hole 232 of the photovoltaic module 2, the end of the pin 5 is inserted into the insertion tube 4. Since the insertion tube 4 is set on the fixing frame 1 and its position is fixed, the position of the photovoltaic module 2 is locked by the insertion and cooperation between the locking hole 232, the pin 5 and the insertion tube 4. When it is necessary to adjust the position of the photovoltaic module 2 and the orientation of the light-receiving surface, it is only necessary to remove the pin 5 from the insertion tube 4. The photovoltaic module 2 can then rotate around the axis of the horizontal axis 11 as the center line, thereby adjusting the position of the light-receiving surface of the photovoltaic module 2 and adjusting it to the power generation position or the cleaning position.

[0042] A further improvement is that the mounting bracket 1 includes a base 13 fixed between the bottoms of the columns 12, and the insertion tube 4 is disposed on the base 13 and extends in the vertical direction.

[0043] The base 13 is elongated and fixed between the bottoms of the two columns 12. The insertion tube 4 extends vertically upward and is fixed to the base 13. With the above structure, the locking component 3 is located at the bottom of the photovoltaic module 2, which lowers the height of the locking component 3 and further facilitates the operation of the locking component 3.

[0044] To increase the structural strength of the fixing frame 1, the tops of the two columns 12 are fixedly connected by a top rod 14, the axis of which is parallel to the axis of the horizontal axis 11.

[0045] A further improvement is that the photovoltaic module 2 includes a photovoltaic cell 21 and four frame profiles surrounding the photovoltaic cell 21 and connected end to end in sequence. Among the four frame profiles, two are rotating profiles 22 that are sealed and sleeved outside the horizontal axis 11 and extend along an axis perpendicular to the horizontal axis 11, and the remaining two are positioning profiles 23 that extend along an axis parallel to the horizontal axis 11. Locking holes 232 are provided on the positioning profiles 23.

[0046] Specifically, such as Figure 4 and Figure 5 As shown, in photovoltaic module 2, rotating profiles 22 and positioning profiles 23 are distributed at intervals along their circumference. The length of rotating profile 22 is greater than the length of positioning profile 23. Rotating profiles 22 and positioning profiles 23 are connected by corner brackets 24. In this way, two rotating profiles 22 and two positioning profiles 23 are connected end to end to form a closed-loop frame structure that surrounds photovoltaic cell 21. Both rotating profiles 22 and positioning profiles 23 are provided with assembly grooves extending along their own length direction. The assembly grooves are sealed to the side of photovoltaic cell 21. Photovoltaic cell 21 uses Topcon modules. Compared with other photovoltaic power generation modules, Topcon modules have higher photoelectric conversion efficiency, exhibit lower degradation rate in long-term operation, and their performance decreases less when the temperature rises, i.e., they have a better temperature coefficient. Thus, photovoltaic cell 21 has higher power generation gain, ensuring long-term power generation stability and high efficiency, and can maintain high power generation efficiency under high temperature and sunlight conditions.

[0047] A further improvement is that a rotating sleeve 221 is sealed and fixedly inserted on the rotating profile 22, the rotating sleeve 221 is sealed and sleeved outside the horizontal shaft 11 and extends in a direction perpendicular to the length direction of the rotating profile 22; a positioning sleeve 231 is sealed and fixedly inserted on the positioning profile 23, and the inner cavity of the positioning sleeve 231 is a lock hole 232.

[0048] Specifically, both the rotating sleeve 221 and the positioning sleeve 231 are metal sleeves, welded to the rotating profile 22 and the positioning profile 23 respectively. The inner diameter of the rotating sleeve 21 is consistent with the outer diameter of the horizontal axis 11. This ensures that the photovoltaic module 2 can rotate stably around the axis of the horizontal axis 11. In addition, the positioning sleeve 231 seals through the positioning profile 23, and the rotating sleeve 221 seals through the rotating sleeve 221, effectively ensuring the airtightness of the four frame profiles and preventing rainwater and moisture from seeping into the photovoltaic cells 21 through the inside of the frame profiles, thus ensuring the normal use of the photovoltaic cells 21.

[0049] A further improvement is that a handle 8 is fixed to the end of the pin 5 away from the insertion tube 4.

[0050] Specifically, the handle 8 is elongated, with its length perpendicular to the axis of the pin 5. The handle 8 facilitates control of the pin 5, enabling locking or unlocking of the photovoltaic module 2.

[0051] Second Embodiment

[0052] like Figures 6-10 As shown, the second embodiment of the photovoltaic railing for balconies based on Topcon components of this utility model is based on the first embodiment, but the difference is that the pin 5 includes a thin rod 52 and a locking bar 53 connected in sequence and perpendicular in length direction. The axial direction of the thin rod 52 is consistent with the axial direction of the pin 5. The projection of the thin rod 52 along its own axial direction is located within the projection of the locking bar 53 along the axial direction of the thin rod 52. A cover plate 6 is provided at the top of the insertion tube 4. A strip hole 61 for the locking bar 53 to pass through is provided on the cover plate 6. An elastic element 7 is provided inside the insertion tube 4. The elastic element 7 is used to lock the locking bar 53 to the bottom of the cover plate 6.

[0053] Specifically, the outer diameter of the thin rod 52 is smaller than the width of the lock bar 53, and the width and length of the lock bar 53 are both smaller than the inner diameter of the lock hole 232. The axis of the thin rod 52 passes through the center of the lock bar 53. The length and width of the lock bar 53 are both smaller than the length and width of the strip hole 61, and the length of the lock bar 53 is greater than the width of the strip hole 61.

[0054] With the above structure, when locking the photovoltaic module 2 at the power generation station or cleaning station, the locking bar 53 and the thin rod 52 are passed through the locking hole 232 in sequence. The locking bar 53 is aligned with the strip hole 61. After the locking bar 53 is passed through the strip hole 61, it abuts against the top of the elastic member 7. Then the locking bar 53 is rotated so that the projection of the locking bar 53 on the horizontal plane intersects with the projection of the strip hole 61 on the horizontal plane, and the horizontal projection of the end of the locking bar 53 protrudes outside the horizontal projection of the strip hole 61. The handle 8 is released, and the elastic member 7 pushes the locking bar 53 upward so that the locking bar 53 abuts against the top of the cover plate 6, thereby preventing the locking bar 53 from falling off the cover plate 6, thus preventing the pin 5 from falling off the insertion tube 4, and ensuring the position locking of the photovoltaic module 2.

[0055] When it is necessary to adjust the position of the photovoltaic module 2, the locking bar 53 is rotated by the handle 8 so that the projection of the locking bar 53 on the horizontal plane is inside the projection of the strip hole 61 on the horizontal plane. Then, the handle 8 is lifted upward so that the locking bar 53 is disengaged from the strip hole 61, and the pin 5 is disengaged from the insertion tube 4, so that the photovoltaic module 2 can be rotated to adjust the position.

[0056] A further improvement is that the bottom surface of the cover plate 6 is provided with a recess 62 to accommodate the locking bar 53. By providing a recess 62 to accommodate the locking bar 53 on the bottom surface of the cover plate 6, and with the elastic element 7 pressing the locking bar 53 against the recess 62, the range of motion of the locking bar 53 is limited. This prevents the locking bar 53 from passing through the strip hole 61 without external operation, further ensuring a stable connection between the pin 5 and the insertion tube 4, and achieving a good locking effect at the photovoltaic module 2 station.

[0057] A further improvement is that the pin 5 also includes a pivot 51 fixed to the end of the thin rod 52 away from the locking bar 53, and the locking hole 232 is a cylinder with an inner diameter consistent with the pivot 51.

[0058] Specifically, the rotating shaft 51 and the thin rod 52 are coaxially connected, with the end of the rotating shaft 51 away from the thin rod 52 fixedly connected to the handle 8. To facilitate the fixing of the cover plate 6 to the top of the insertion tube 4, a screw tube 63 is provided on the outer circumferential edge of the cover plate 6. The screw tube 63 is threadedly connected to the top of the insertion tube 4 and sleeved on the outside of the top of the insertion tube 4. The elastic element 7 includes a compression spring 71, with a fixing block 72 and a pressure plate 73 connected to both ends of the compression spring 71, respectively. The fixing block 72 is fixed to the top inside the insertion tube 4, and the pressure plate 73 is disc-shaped with an outer diameter consistent with the inner diameter of the insertion tube 4, which facilitates movement along the axial direction of the insertion tube 4. When the locking bar 53 passes through the strip hole 61 and abuts against the pressure plate 73, the compression spring 71 contracts, and the pressure plate 73 moves upward by its own elastic force, lifting the locking bar 53.

[0059] By using the matching rotating shaft 51 and locking hole 232, it is convenient for the rotating shaft 51 and the thin rod 52 to rotate around their own axis after the rotating shaft 51 is inserted into the locking hole 232, so as to adjust the angle of the locking bar 53. When the projection of the locking bar 53 on the horizontal plane is located inside the projection of the strip hole 61 on the horizontal plane, it is convenient for the locking bar 53 to pass through the strip hole 61. Otherwise, when the locking bar 53 is located below the cover plate 6 and the horizontal projection of the end of the locking bar 53 protrudes outside the horizontal projection of the strip hole 61, the locking bar 53 cannot disengage from the insertion tube 4, thereby ensuring that the locking component 3 locks the photovoltaic module 2 station well.

[0060] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
