Description

Technical Field

[0001] This application relates to the field of photovoltaic roofing technology, and more specifically to a photovoltaic roofing structure that facilitates drainage. Background Technology

[0002] Currently, photovoltaic power generation is a new type of electricity production that is highly environmentally friendly and energy-saving, among which photovoltaic roof technology, which combines photovoltaic modules with the roof of a building, is becoming increasingly common.

[0003] Most existing photovoltaic roof structures have multiple interconnected water channels at the installation locations of photovoltaic products. These channels are mostly divided into horizontal and vertical channels for drainage. The water channels formed by the horizontal and vertical channels are usually set at the same height. The vertical channels generally have a height difference to allow water to flow out normally under gravity. However, because the horizontal channels are set at the same height as the vertical channels, some water accumulates in the horizontal channels during the flow, resulting in poor drainage and affecting the overall drainage efficiency.

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0022] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] refer to Figures 1 to 5 A preferred embodiment of the photovoltaic roof structure for easy drainage according to this application will be described in detail below. The photovoltaic roof structure for easy drainage is used to be mounted on the top of a building 90. The photovoltaic roof structure for easy drainage includes a main frame 10 and a plurality of photovoltaic units 20.

[0025] Specifically, the main frame 10 includes a plurality of longitudinal frames 11 and a plurality of transverse frames 12, wherein the plurality of longitudinal frames 11 are evenly and spaced apart on a plurality of parallel planes, and each longitudinal frame 11 is provided to be recessed from top to bottom to form a longitudinal channel 1101, and the two ports of the longitudinal channel 1101 extend to the two ends of the longitudinal frame 11 respectively.

[0026] Preferably, each of the longitudinal frames 11 is configured as a generally herringbone structure, that is, a structure that is high in the middle and low at both ends.

[0027] A plurality of transverse frames 12 are evenly and spaced apart, extending along the direction of the arrangement of the plurality of longitudinal frames 11. Each transverse frame 12 is recessed from top to bottom to form a transverse channel 1201. The two ends of the transverse channel 1201 extend to the two ends of the transverse frame 12, and the two ends of one transverse frame 12 are respectively connected to the top ends of two adjacent longitudinal frames 11. The two ends of one transverse channel 1201 are respectively connected to two adjacent longitudinal channels 1101. Furthermore, each end of each transverse frame 12 is inclined from top to bottom toward two adjacent longitudinal frames 11 to form an inclined portion 121, and the two inclined portions 121 of each transverse frame 12 extend into the interior of two adjacent longitudinal channels 1101.

[0028] It should be noted that rainwater in each of the transverse channels 1201 can flow through the two inclined portions 121 respectively along the extension direction of the transverse channel 1201 under the action of gravity. At the same time, since the inclined portion 121 is inclined, rainwater can quickly flow into the longitudinal channel 1101 and then flow out of the longitudinal frame 11 from the longitudinal channel 1101.

[0029] Multiple photovoltaic units 20 are evenly and spaced apart along the arrangement direction of multiple longitudinal frames 11, and one photovoltaic unit 20 is connected to the top of two adjacent transverse frames 12. At least one pair of photovoltaic units 20 are symmetrically arranged on both sides of a longitudinal channel 1101, forming a longitudinal channel 201 between them, and one longitudinal channel 201 connects to one longitudinal channel 1101. In addition, at least one pair of photovoltaic units 20 are symmetrically arranged on both sides of a transverse channel 1201, forming a transverse channel 202 between them, and one transverse channel 202 connects to one transverse channel 1201.

[0030] Those skilled in the art will understand that when the photovoltaic roof structure with easy drainage is in a rainy environment, rainwater can flow into the longitudinal channel 1101 along the longitudinal channel 201 and into the transverse channel 1201 along the transverse channel 202. A portion of the rainwater that directly enters the longitudinal channel 1101 can flow directly out of the longitudinal frame 11 along the extension direction of the longitudinal channel 1101. Conversely, a portion of the rainwater that enters the transverse channel 1201 can flow along the extension direction of the transverse channel 1201 under the influence of gravity until it flows into the longitudinal channel 1101, and then flows out of the longitudinal frame 11 along the extension direction of the longitudinal channel 1101, thus allowing the rainwater to flow out from the photovoltaic roof structure with easy drainage.

[0031] Furthermore, due to the height difference between the longitudinal frame 11 and the transverse frame 12, there is also a height difference between the longitudinal channel 1101 and the transverse channel 1201. This makes it difficult for rainwater flowing in the longitudinal channel 1101 to flow from the longitudinal channel 1101 to the transverse channel 1201, thereby preventing some rainwater from accumulating in the transverse channel 1201. At the same time, the transverse frame 12 is also provided with the inclined part 121 to accelerate the flow of rainwater, so as to shorten the rainwater retention time in each transverse channel 1201, thereby achieving the purpose of rapid drainage.

[0032] In this way, the drainage efficiency of the photovoltaic roof structure that facilitates drainage is improved.

[0033] Preferably, each of the longitudinal channels 1101 is provided to extend at an angle so that the extension direction of the longitudinal channel 1101 of each of the longitudinal frames 11 forms an angle with the axial direction of the longitudinal frame 11. In this way, the retention time of rainwater in the longitudinal channel 1101 is shortened, and it can flow out of the longitudinal frame 11 quickly under the action of gravity.

[0034] It is worth mentioning that when each of the longitudinal frames 11 is configured as a generally herringbone structure, as a variation, the bottom wall of each of the longitudinal frames 11 forming the longitudinal channel 1101 is configured to bulge upward from the middle position, so that the cross-sectional shape of each of the longitudinal channels 1101 is configured to tend to be herringbone, that is, the longitudinal channel 1101 formed by each of the longitudinal frames 11 tends to have a structure that is high in the middle and low at both ends.

[0035] Preferably, each of the transverse channels 1201 is provided to extend at an angle so that the extension direction of the transverse channel 1201 of each transverse frame 12 forms a predetermined angle with the axial direction of the transverse frame 12. In this way, the retention time of rainwater in the transverse channel 1201 is further shortened, and it can flow out of the transverse frame 12 quickly under the action of gravity.

[0036] It is worth mentioning that, as an alternative, the bottom wall of each of the transverse frames 12 forming the transverse channel 1201 is provided to protrude upward from the middle position, so that the cross-sectional shape of each of the transverse channels 1201 tends to be an arc structure, thereby allowing rainwater to flow out quickly from the two ports of each of the transverse channels 1201 under the action of gravity.

[0037] Preferably, the main frame 10 further includes a plurality of transverse support frames 13, wherein the plurality of transverse support frames 13 are evenly spaced and extend along the direction in which the plurality of longitudinal frames 11 are arranged, and one transverse support frame 13 is connected to the bottom end of the plurality of longitudinal frames 11. In other words, one transverse support frame 13 can be connected to the plurality of longitudinal frames 11, thereby maintaining the structural stability of the main frame 10.

[0038] More preferably, the main frame 10 further includes a plurality of longitudinal support frames 14, which are evenly and spaced apart on a plurality of parallel planes, and at least one of the longitudinal support frames 14 is disposed between two adjacent longitudinal frames 11, and the bottom end of one of the longitudinal support frames 14 is connected to the top end of the plurality of transverse support frames 13. In addition, the arrangement direction of the plurality of longitudinal support frames 14 is arranged to coincide with the arrangement direction of the plurality of longitudinal frames 11, so that the plurality of longitudinal support frames 14 and the plurality of longitudinal frames 11 are kept flush.

[0039] It is understood that the longitudinal support frame 14, by connecting with the transverse support frame 13, can not only further maintain the structural stability of the main frame 10, but also, when the transverse frame 12 is connected to two adjacent longitudinal frames 11, the longitudinal support frame 14 can play a supporting role at the middle position of the transverse frame 12. Thus, the photovoltaic unit 20 connected to the top of the two adjacent transverse frames 12 can be supported by the longitudinal support frame 14 supporting the transverse frame 12.

[0040] Preferably, each of the longitudinal support frames 14 is configured as a generally herringbone structure, that is, a structure that is high in the middle and low at both ends.

[0041] Preferably, the main frame 10 is made of a corrosion-resistant material, such as aluminum alloy.

[0042] Furthermore, the photovoltaic roof structure that facilitates drainage also includes a fixing member 30, which is used to maintain the connection state of the photovoltaic unit 20.

[0043] Preferably, the fixing member 30 includes a plurality of first fixing members 31, wherein at least one of the first fixing members 31 is detachably connected to the bottom wall of one of the longitudinal channels 1101 and located between two adjacent photovoltaic units 20, and the top end of each of the first fixing members 31 extends toward the two adjacent photovoltaic units 20 respectively to form a first pressing part 311 above the edges of the two adjacent photovoltaic units 20 respectively to abut against the edges of the two photovoltaic units 20 respectively.

[0044] It is understood that at least some of the photovoltaic units 20 can be stabilized by having their edges abutted at both ends by the first pressing portion 311 of the first fastener 31. Furthermore, the number of first fasteners 31 located between adjacent photovoltaic units 20 is set to at least one, thereby increasing the fixed area of ​​the edges of the photovoltaic units 20 to further stabilize the connection.

[0045] Furthermore, the fixing member 30 also includes a plurality of second fixing members 32, wherein the plurality of second fixing members 32 are detachably connected in a uniformly arranged manner to the longitudinal channels 1101 of the two longitudinal frames 11 located at the periphery of the main frame 10, and each second fixing member 32 is provided to extend above the edge of a photovoltaic unit 20 to form a second pressing part 321. Thus, when the plurality of second fixing members 32 are uniformly connected to the two longitudinal frames 11, the second pressing part 321 of each second fixing member 32 is provided to press against the edge of the photovoltaic unit 20 away from the first pressing part 311.

[0046] It is understood that only one end of the photovoltaic unit 20 located at the edge of the main frame 10 is pressed against by the first fixing member 31, while the second fixing member 32 can press against the other end of the photovoltaic unit 20 away from the first fixing member 31 through the second pressing part 321. In this way, at least two ends of the photovoltaic unit 20 located at the edge of the main frame 10 are pressed against, thus maintaining a stable connection. It is worth mentioning that the photovoltaic unit 20 located at the edge of the main frame 10 is configured to have its edge portion pressed against by at least one of the second fixing members 32.

[0047] Furthermore, the photovoltaic roof structure for easy drainage also includes multiple edge water guide plates 40. Preferably, each edge water guide plate 40 has a connecting portion 41 and a water guiding portion 42 connected to the connecting portion 41. An angle is formed between the connecting portion 41 and the water guiding portion 42 of each edge water guide plate 40. The connecting portion 41 of each edge water guide plate 40 extends towards the bottom end of a photovoltaic unit 20 until it connects to a photovoltaic unit 20 located at the edge of the main frame 10. A water guiding portion 42 is connected to the top of two adjacent longitudinal frames 11 and located at the edge of the main frame 10. Each water guiding portion 42 is evenly and spaced along a direction parallel to the arrangement direction of the longitudinal frames 11.

[0048] It is understood that rainwater falling on the edge water guide plate 40 can be separated from the edge water guide plate 40 under the action of gravity along the extension direction of the water guide part 42, and thus be separated from the entire photovoltaic roof structure that facilitates drainage.

[0049] It is worth mentioning that the water guiding portion 42 of each of the edge water guiding plates 40 is also connected to the top of at least one of the longitudinal support frames 14, so that the middle position of the edge water guiding plate 40 can also be supported by the longitudinal support frame 14.

[0050] In one embodiment, specifically as follows Figure 1 or Figure 5 As shown, each of the longitudinal frames 11 further includes a first segment 111 and a second segment 112, wherein the top ends of the first segment 111 and the second segment 112 of each longitudinal frame 11 respectively have a first channel and a second channel, and the first segment 111 and the second segment 112 of each longitudinal frame 11 are connected at an angle to each other, so that a first channel and a second channel communicate to form a longitudinal channel 1101. Furthermore, a plurality of first segments 111 are evenly and spaced apart on a plurality of parallel planes, and a plurality of second segments 112 are evenly and spaced apart on a plurality of parallel planes.

[0051] It is worth mentioning that at least a portion of the transverse frame 12 is uniformly connected to the top of the first segment 111, and at least another portion of the transverse frame 12 is uniformly connected to the top of the second segment 112. At least a portion of the transverse support frame 13 is uniformly connected to the bottom of the first segment 111, and at least another portion of the transverse support frame 13 is uniformly connected to the bottom of the second segment 112.

[0052] Preferably, each of the first components 111 extends toward the photovoltaic unit 20 to form at least one first partition 1111, and each of the first partitions 1111 is configured to fill the gap between each photovoltaic unit 20 and the first component 111. Correspondingly, each of the second components 112 extends toward the photovoltaic unit 20 to form at least one second partition 1121, and each of the second partitions 1121 is configured to fill the gap between each photovoltaic unit 20 and the second component 112.

[0053] Thus, rainwater is less likely to enter the interior of the building 90 through the drainage-friendly photovoltaic roof structure.

[0054] Preferably, the photovoltaic roof structure for easy drainage further includes a ridge plate 50. Preferably, the ridge plate 50 also has a receiving groove 501 for receiving the connection point where the first segment 111 and the second segment 112 of each of the longitudinal frames 11 are connected. The opposite sides of the ridge plate 50 forming the receiving groove 501 are respectively connected to at least one of the transverse frames 12 closest to the ridge plate 50. Furthermore, the top of the ridge plate 50 is provided with a guide portion 51 that slopes downwards towards the interior of each transverse channel 1201 closest to the sides of the ridge plate 50, guiding rainwater flow towards the transverse channel 1201.

[0055] It is worth mentioning that the guide portion 51 of the ridge plate 50 also passes above at least one of the longitudinal channels 1101, that is, some of the rainwater flowing through the guide portion 51 can flow directly into at least one of the longitudinal channels 1101 under the action of gravity.
