Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and in particular to a roof BIPV photovoltaic module. Background Art

[0002] Photovoltaic BIPV roofing technology is an innovative technology that perfectly integrates photovoltaic modules with building roofs. This technology achieves a dual improvement in building appearance and power generation function by directly integrating solar panels into building roofing materials. BIPV roofing technology not only has the power generation capacity of traditional photovoltaic systems, but also has multiple functions such as waterproofing, heat insulation, and aesthetics. It adopts customized design to ensure that photovoltaic modules and building roofs are perfectly matched, which not only does not destroy the overall beauty of the building, but also improves the practicality and environmental protection of the building.

[0003] A Chinese patent with application number 2023101799097 discloses a photovoltaic roof, which includes a roof body, support beams are arranged on both sides of the ridge, a supporting member is arranged on the side of the support beam close to the ridge, an opening is arranged on the side of the support beam away from the ridge, a downward flange is arranged on the top of the opening, and a supporting sheet is arranged on the bottom of the opening; a row of photovoltaic components is arranged between two adjacent support beams, and the photovoltaic components include a photovoltaic panel body, a first supporting frame and a second supporting frame, the first supporting frame is overlapped on the supporting member, and the second supporting frame is overlapped on the supporting sheet. The application has the effect of improving the waterproof performance of the photovoltaic roof.

[0004] A Chinese patent with application number 202311472169.2 discloses a BIPV photovoltaic device and a BIPV photovoltaic system. The BIPV photovoltaic device includes a supporting mechanism, a telescopic mechanism, a photovoltaic module and an installation component installed on a building wall. The supporting mechanism includes a base with a slide groove, and the base is installed below the roof installation opening; the telescopic mechanism is installed on the base, and the telescopic mechanism includes a scissor-type connection component and a rotating component. The state of the photovoltaic module is adjusted by a driving mechanism. When the photovoltaic module is in a folded state, the photovoltaic module is folded to expose the roof, so that the interior of the building receives sunlight. The photovoltaic module rotates to a horizontal position, and the photovoltaic module is in an unfolded state. The photovoltaic module covers the roof after unfolding.

[0005] Photovoltaic facilities similar to the above-mentioned prior art will accumulate dust and dirt on the surface of their photovoltaic modules during long-term use, affecting the transmittance of light, thereby reducing the photoelectric conversion efficiency. Long-term cleaning will lead to a decrease in power generation and fail to meet actual needs. The surface of the photovoltaic modules needs to be cleaned regularly, but the cleaning effect of the photovoltaic modules using wind power in the prior art is poor and cannot effectively separate stubborn dirt from the photovoltaic modules.

[0006] At the same time, since photovoltaic modules are installed on the roof, it is inevitable that birds will stay on the photovoltaic roof. Since most birds are gregarious, if the birds on the photovoltaic modules are not driven away in time, a large number of birds will stay or build nests on the photovoltaic roof, resulting in light being blocked by birds and reduced power generation. At the same time, photovoltaic modules will also be damaged by bird activities, such as trampling, pecking and other problems. Moreover, bird excrement is highly corrosive, and long-term accumulation will erode the surface of photovoltaic panels, affecting the light transmittance and power generation efficiency of photovoltaic modules. In addition, bird droppings may also cause hot spot effects, resulting in local overheating of modules and even fire.

[0007] Therefore, it is necessary to invent a roof BIPV photovoltaic module to solve the above problems. Summary of the invention

The reflector can drive the rotating member to rotate with the help of wind force and reflect light irregularly.

[0012] The lower end of the rotating member passes through the connecting member and is fixedly connected with an elliptical rotating block. The upper half of the axial side of the rotating block is provided with a plurality of electromagnetic parts in a ring array. When the electromagnetic parts are energized and generate magnetic attraction, the rotating block is magnetically attracted to the traction member through the electromagnetic parts; when the electromagnetic parts are not energized, the rotating block is in sliding contact with the traction member.

[0015] Preferably, a slide groove is provided in the sliding member, and a plurality of limit grooves are provided in a linear array in the slide groove, and a hinge ball is fixedly connected to one end of each cleaning roller away from the ridge, and the hinge ball is located in the limit groove and can slide horizontally in the slide groove.

[0019] Technical effects and advantages of the present invention:

[0020] 1. The present invention cooperates with the anti-interference part and the traction part. When the wind pushes the reflector to rotate, the reflector can drive the rotating part to rotate through the rotating ring. At this time, the reflector drives away birds by reflecting light. At the same time, the rotating reflector disturbs the birds landing on the two ends of the roof. Since the rotating block and the traction part are in contact with each other, the traction part will not rotate with the rotating block, but will be continuously vibrated by the thrust of the longer side of the rotating block, so that the birds landing on the traction part cannot find an effective force point, thereby effectively expelling the birds landing on the roof and avoiding the problem of birds blocking the photovoltaic panels and reducing the power generation.

[0021] 2. The present invention achieves mutual cooperation between the anti-interference part and the traction part, and a plurality of limit blocks are arranged on the traction part, and reciprocate along the width direction of the roof ridge under the action of gravity and the drive of the traction part. The limit blocks drive the cleaning roller to slide between the two photovoltaic panels through the connecting line, so as to clean up the dust and debris blocked between the two photovoltaic panels, thereby avoiding excessive accumulation of debris and eventually covering the surface of the photovoltaic panels. At the same time, the reciprocating motion of the cleaning roller causes the plurality of photovoltaic panels to vibrate slightly under the action of friction, so as to clean up the dust accumulated on the surface of the photovoltaic panels, and at the same time, it can avoid the problem of birds landing on the surface of the photovoltaic panels and directly damaging the surface of the photovoltaic panels.

[0022] 3. The present invention arranges a cleaning roller in the drainage trough and makes the cleaning roller cooperate with the anti-interference part and the traction part. On the one hand, it prevents the drainage trough from losing its drainage function due to excessive dust and debris accumulated over a long period of time. On the other hand, it cooperates with the anti-interference part and the traction part to reciprocate on the surface of the photovoltaic panel to effectively clean the bird droppings thereon.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-2 As shown, the first embodiment of the present invention provides a roof BIPV photovoltaic module, including a support part 1, the support part 1 includes a ridge 11, two roofs 12 are symmetrically installed on both sides of the ridge 11, each roof 12 is composed of a plurality of criss-crossing support beams, and each roof 12 is provided with a plurality of drainage grooves 13 in a linear array, one end of each drainage groove 13 is fixedly connected to the ridge 11, and a sliding member 14 is fixedly connected above the other end, and the plurality of support beams are divided into two layers, the support beams located in the lower layer are arranged in an array along the length direction of the ridge 11, and the support beams located in the upper layer are arranged in an array along the width direction of the ridge 11, and the bottom of the support beams located in the lower layer is provided with a plurality of support rods in a linear array to provide support for the photovoltaic module, and a reinforcing rod is fixedly connected between two adjacent support rods to further improve the stability of the device, and a plurality of drainage grooves 13 are arranged in an array above the support beams located in the upper layer.

[0039] In this embodiment, the roof BIPV photovoltaic assembly also includes a photovoltaic panel 2, which is used to convert light energy into electrical energy. Two adjacent photovoltaic panels 2 distributed along the width direction of the ridge 11 are connected by a U-shaped gutter, and two adjacent photovoltaic panels 2 distributed along the length direction of the ridge 11 are connected by a drainage trough 13. By tilting the two roofs 12 so that the ridge 11 is higher than the roof 12, dust and rainwater falling on the photovoltaic panel 2 slide downward along the surface of the photovoltaic panel 2 under the action of gravity and fall into the U-shaped gutter and the drainage trough 13 respectively, thereby collecting the dust and impurities on the photovoltaic panel 2.

[0040] In this embodiment, the roof BIPV photovoltaic assembly also includes an anti-interference part 4, which is arranged on the supporting part 1, and the anti-interference part 4 includes a connecting member 41, which is fixedly connected to one end of the ridge 11, and a rotating member 42 is rotatably connected to the top of the connecting member 41, and a rotating ring 43 is fixedly connected to the upper end of the rotating member 42, and a plurality of connecting rods 44 are arranged in a circular array on the axial side of the rotating ring 43, and each connecting rod 44 is provided with a hemispherical reflector 45 at one end away from the rotating ring 43, and the reflector 45 can drive the rotating member 42 to rotate with the help of wind force, and disturb birds by irregular reflection of light. Through the setting of the rotating ring 43, when the reflector 45 is subjected to wind force, it can drive the rotating ring 43 and the rotating member 42 to rotate synchronously. On the one hand, the rotating reflector 45 disturbs the birds falling on the ridge 11, and on the other hand, by coating reflective paint on the reflector 45, the reflector 45 causes irregular reflection of light during rotation, thereby further improving the effect of expelling birds.

[0041] like Figure 1-Figure 8 As shown, in another embodiment of the present invention, a sliding groove is provided on one side of the connecting member 41, and a traction part 5 is provided in the sliding groove, the traction part 5 includes a traction seat 51, the traction seat 51 is slidably connected to the connecting member 41, the traction seat 51 and the sliding groove are connected by an electrically controlled telescopic rod 52, an elastic rod 53 is fixedly connected to the end of the traction seat 51 away from the sliding groove, a traction ring 54 is provided at the end of the elastic rod 53 away from the traction seat 51, a traction ring 54 is provided in the traction ring 54, and a traction member 55 is provided in the traction ring 54, by respectively arranging an anti-interference part 4 at both ends of the ridge 11, and respectively arranging a traction part 5 on the two anti-interference parts 4, and making the same traction member 55 pass through the two traction rings 54 to form a ring structure, thereby reducing the footholds of birds on the ridge 11, and further improving the bird expelling effect of the device.

[0042] At the same time, the two elastic rods 53 are provided to keep the traction member 55 in a taut state at all times, so as to prevent the traction member 55 from bending downward under the action of gravity and fitting with the roof ridge 11 to lose the restraining effect on the birds.

[0043] In this embodiment, the lower end of the rotating member 42 passes through the connecting member 41 and is fixedly connected with an elliptical rotating block 46. The upper half of the axial side of the rotating block 46 is provided with a plurality of electromagnetic parts 47 in a ring array. When the electromagnetic part 47 is energized and generates magnetic attraction, the electromagnetic part 47 and the traction member 55 are magnetically attracted, and the rotating block 46 is magnetically connected to the traction member 55 through the electromagnetic part 47; when the electromagnetic part 47 is not energized, the rotating block 46 is in sliding contact with the traction member 55. When the rotating member 42 is driven by the reflector 45 to rotate, and the electromagnetic part 47 is not energized, the rotating member 42 will synchronously drive the rotating block 46 to rotate. During this process, since the traction member 55 is arranged on the outside of the elliptical rotating block 46, when the rotating block 46 rotates, the longer side of the rotating block 46 will push the traction member 55 to continuously change. At this time, since the rotating block 46 and the traction member 55 are in sliding fit, the traction member 55 will not rotate with the rotating block 46, but will be continuously shaken by the thrust of the longer side of the rotating block 46, so that the birds that land on the traction member 55 cannot find an effective foothold, further avoiding the harm of birds to the photovoltaic panel 2, and at the same time making up for the disadvantage that the anti-interference part 4 can only expel the birds at both ends of the ridge 11.

[0044] like Figure 1-Figure 8 As shown, in another embodiment of the present invention, the photovoltaic assembly also includes a cleaning part 3, which is arranged between two adjacent photovoltaic panels 2 distributed along the length direction of the ridge 11, and the cleaning part 3 is used to clean the surface of the photovoltaic panel 2, and the anti-interference part 4 cooperates with the cleaning part 3, and the anti-interference part 4 is driven by wind to rotate and cooperate with the movement of the cleaning part 3 to drive away birds, and at the same time, the anti-interference part 4 drives the cleaning part 3 to slide on the photovoltaic panel 2 to clean the photovoltaic panel 2.

[0045] In this embodiment, the cleaning portion 3 includes a limit block 33, and a plurality of limit blocks 33 are arranged in a linear array on the traction member 55. A connecting line 32 is provided on the side of each limit block 33 close to the photovoltaic panel 2, and a cleaning roller 31 is slidably sleeved on the outer side of each connecting line 32. The cleaning roller 31 is located between the two photovoltaic panels 2. When the reflector 45 drives the rotating member 42 to rotate under the action of wind, the rotating member 42 can drive the elliptical rotating block 46 to rotate.

[0046] If the long axis end of the rotating block 46 rotates from the length direction of the roof ridge 11 to the width direction of the roof ridge 11, the short axis of the elliptical structure formed by the traction members 55 connected end to end will become longer, and the long axis will become shorter. Conversely, if the long axis end of the rotating block 46 rotates from the width direction of the roof ridge 11 to the length direction of the roof ridge 11, the short axis of the elliptical structure formed by the traction members 55 connected end to end will become shorter, and the long axis will become longer. In this process, the multiple limit blocks 33 arranged on the traction member 55 can be driven by gravity and the traction member 55 to move along the roof ridge 11. The ridge 11 reciprocates in the width direction, and the limit block 33 drives the cleaning roller 31 to slide between the two photovoltaic panels 2 through the connecting line 32, so as to clean the dust and debris blocked between the two photovoltaic panels 2, thereby preventing excessive accumulation of debris and eventually covering the surface of the photovoltaic panel 2. At the same time, through the reciprocating motion of the cleaning roller 31, the multiple photovoltaic panels 2 are vibrated slightly under the action of friction, so as to clean the dust accumulated on the surface of the photovoltaic panel 2, and at the same time, it is avoided that birds fall on the surface of the photovoltaic panel 2 and directly damage the surface of the photovoltaic panel 2.

[0047] In this embodiment, a slide groove 15 is provided in the sliding member 14, and a plurality of limit grooves 16 are provided in a linear array in the slide groove 15. A hinge ball 34 is fixedly connected to one end of each cleaning roller 31 away from the ridge 11. The hinge ball 34 is located in the limit groove 16 and can slide horizontally in the slide groove 15. A plurality of clamping members 17 are provided in a linear array on each drainage groove 13. Each clamping member 17 can clamp and fix two photovoltaic panels 2 at the same time. The cleaning roller 31 is slidably connected to the clamping member 17. The connection between the slide groove 15 and the limiting groove 16 is wedge-shaped, so that the hinge ball 34 can slide from the limiting groove 16 to the slide groove 15. The clamping member 17 includes a fixed block 171, and the fixed block 171 is fixedly connected to the drainage groove 13. A clamping block 172 is fixedly connected above the fixed block 171. The photovoltaic panel 2 can be clamped by the mutual cooperation of the clamping block 172 and the fixed block 171. A slide rail compatible with the cleaning roller 31 is provided on the top of the clamping block 172, and the side of the slide rail is a wedge surface.

[0048] First, through the cooperation between the anti-interference part 4 and the traction part 5, when the wind pushes the reflector 45 to rotate, the reflector 45 can drive the rotating member 42 to rotate through the rotating ring 43. At this time, the reflector 45 drives away birds by reflecting light, and at the same time, the rotating reflector 45 disturbs the birds landing on the two ends of the roof ridge 11 by rotating; in this process, the electromagnetic part 47 is not energized, and the rotating block 46 and the traction member 55 are in contact with each other, but will not drive the traction member 55 to rotate. At this time, the rotating member 42 will synchronously drive the rotating block 46 to rotate. The guide member 55 is arranged on the outside of the elliptical rotating block 46. When the rotating block 46 rotates, the long axis of the rotating block 46 will push the traction member 55 to change continuously. At this time, due to the contact between the rotating block 46 and the traction member 55, the traction member 55 will not rotate with the rotating block 46, but will be continuously vibrated by the thrust of the longer side of the rotating block 46, so that the birds that land on the traction member 55 cannot find an effective foothold, thereby effectively expelling the birds that land on the ridge 11, avoiding the problem of birds blocking the photovoltaic panels 2 and reducing power generation.

[0049] Secondly, when the traction member 55 is continuously reciprocating under the drive of the rotating member 42, the plurality of limit blocks 33 arranged on the traction member 55 reciprocate on the ridge 11 along the width direction of the ridge 11 under the action of gravity and the drive of the traction member 55. At this time, the limit block 33 will drive the cleaning roller 31 to slide between the two photovoltaic panels 2 through the connecting line 32, so as to clean up the dust and debris blocked between the two photovoltaic panels 2, thereby avoiding excessive accumulation of debris and eventually covering the surface of the photovoltaic panel 2. At the same time, through the reciprocating motion of the cleaning roller 31, the plurality of photovoltaic panels 2 are vibrated slightly under the action of friction, so as to clean up the dust accumulated on the surface of the photovoltaic panel 2, and at the same time, avoid the problem of birds landing on the surface of the photovoltaic panel 2 and directly damaging the surface of the photovoltaic panel 2.

[0050] It should be noted that in order to improve the bird-repelling and cleaning effects of the device, a driving motor can be arranged at the bottom of the rotating part 42. When there is no wind blowing in the space where the photovoltaic component is located, the driving motor is controlled to drive the rotating part 42 to rotate, so that the device can continue to clean and repel birds in a windless environment, thereby further protecting the photovoltaic panel 2. At the same time, a water spraying device can be arranged on the photovoltaic component to cool down the photovoltaic component to avoid damage to the photovoltaic component due to excessive temperature.

[0051] Finally, when it is necessary to clean the dust and bird droppings on the photovoltaic panel 2, the electric telescopic rod 52 is controlled to retract upward, so that the electric telescopic rod 52 can drive the traction seat 51 to slide upward, and drive the traction member 55 to move through the traction ring 54, so that it moves from the lower half of the rotating block 46 to the upper half of the rotating block 46 and fits with the electromagnetic part 47 on the rotating block 46. In this process, the traction member 55 will synchronously drive the plurality of limit blocks 33 to move upward, and since the limit blocks 33 are connected to the cleaning roller 31 through the connecting line 32, the limit blocks 33 are connected to the cleaning roller 31 through the connecting line 32. Therefore, when the limit block 33 moves upward, it will drive the end of the cleaning roller 31 close to the ridge 11 to tilt upward. At this time, the hinged ball 34 connected to the other end of the cleaning roller 31 will rotate upward in the limit groove 16 following the cleaning roller 31. In this state, the end of the cleaning roller 31 close to the ridge 11 will move to the upper area of ​​the photovoltaic panel 2, while the cleaning roller 31 close to the hinged ball 34 is still in the slide rail of the clamping block 172, thereby separating the drainage trough 13 from the cleaning roller 31, and cleaning the dust and debris between the two photovoltaic panels 2 from the gap to the outside.

[0052] It should be noted that the telescopic end of the electric-controlled telescopic rod 52 is connected to the traction seat 51, so when the position of the traction seat 51 needs to be adjusted, the telescopic end of the electric-controlled telescopic rod 52 drives the traction seat 51 to move by electric control, thereby adjusting the position of the traction seat 51. The electric-controlled telescopic rod 52 is electrically connected to the controller, and the working state of the electric-controlled telescopic rod 52 can be controlled by the controller; the controller adopts the existing control technology.

[0053] Subsequently, by controlling the electromagnetic part 47 to be energized, the rotating block 46 will be magnetically attracted to the traction member 55 under the action of magnetic force, and by controlling the rotating member 42 to rotate, the rotating member 42 will drive the traction member 55 to rotate through the rotating block 46, so that the multiple limit blocks 33 arranged on the traction member 55 move along the length direction of the roof ridge 11. In this process, due to the rigidity of the cleaning roller 31 itself and the top of the clamping block 172 is provided with a slide rail adapted to the cleaning roller 31, and the side of the slide rail is a wedge surface, so under the driving of the traction member 55 The cleaning roller 31 located in the clamping block 172 will gradually move to the top of the photovoltaic panel 2 through the wedge surface on the side of the slide rail, and move along the length direction of the ridge 11 following the rotation of the traction member 55, so as to clean the surface of the photovoltaic panel 2, and further improve the cleaning effect of the photovoltaic panel 2 by the arranged water spraying device, effectively avoiding the problem that the long-term accumulation of bird excrement will erode the surface of the photovoltaic panel and affect the light transmittance and power generation efficiency of the photovoltaic module, as well as the problem that the bird droppings will cause the hot spot effect, resulting in local overheating and damage of the module, and even cause a fire.

[0054] It should be particularly noted that the present invention provides a cleaning roller 31 in the drainage trough 13 and cooperates with the anti-interference part 4 and the traction part 5. On the one hand, it prevents the drainage trough 13 from losing its drainage function due to excessive dust and debris accumulated over a long period of time. On the other hand, the cleaning roller 31 reciprocates in the drainage trough 13, thereby causing the photovoltaic panel 2 to vibrate slightly through friction, thereby driving away birds that land on the photovoltaic panel 2 and avoiding the problem of birds pecking at the photovoltaic panel 2. At the same time, the anti-interference part 4 and the traction part 5 cooperate to effectively expel birds that land on the roof 11, and reciprocate on the surface of the photovoltaic panel 2 to effectively clean the bird droppings thereon.

[0055] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
