Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a water tank and a photovoltaic power station. Background Art

[0002] In home photovoltaic power plant applications, most systems incorporate waterproofing to meet waterproofing requirements. However, since gaps are inevitable where photovoltaic modules are laid and joined, gutters are installed beneath these gaps to collect rainwater that falls through them, ensuring the power plant's waterproofing.

[0003] At present, the water tank systems used in photovoltaic power stations can be divided into ordinary water tanks and ridge water tanks. However, because water tanks are not universal, they need to be processed and produced with different types of materials corresponding to ordinary water tanks and ridge water tanks respectively. The wide variety of water tanks used leads to increased processing and production, warehousing management, and delivery and transportation costs.

[0004] Based on this, the prior art is in urgent need of a new universal sink that can combine the functions of an ordinary sink and a ridge sink. Utility Model Content

[0005] The main purpose of this application is to propose a water tank and a photovoltaic power station, which aims to take into account the functions of ordinary water tanks and roof water tanks and improve the versatility of the water tank.

[0006] To achieve the above-mentioned purpose, the present application proposes a water tank, which is applied to a photovoltaic power station. The water tank comprises:

[0007] The bottom plate includes a curved section and a plurality of bottom plate sections, wherein the curved section is provided between two adjacent bottom plate sections, and the curved section is used to adjust the angle between the two adjacent bottom plate sections accordingly when bending;

[0008] A first folded edge and a second folded edge are respectively provided on both sides of the bottom plate, and the first folded edge, the bottom plate and the second folded edge enclose the water tank.

[0009] In one embodiment, the cross section of the curved section is arc-shaped.

[0010] In one embodiment, the curved section includes a first plate section and a second plate section, and the first plate section and the second plate section are arranged at an angle.

[0011] In one embodiment, the bottom plate segment has a first end and a second end that are oppositely arranged along the length direction, and a water tongue is provided at the first end and / or the second end of each bottom plate segment.

[0012] In one embodiment, the water tongue is arranged to be inclined outward in a direction away from the bottom plate section.

[0013] In one embodiment, the first folded edge includes a first connecting segment and a second connecting segment connected into one piece, and the second connecting segment is bent relative to the first connecting segment;

[0014] The second folded edge includes a third connecting segment and a fourth connecting segment connected into one piece, the fourth connecting segment is bent relative to the third connecting segment, and the first connecting segment and the third connecting segment are relatively arranged on both sides of the bottom plate.

[0015] In one embodiment, the bending direction of the second connecting segment is the same as or opposite to the bending direction of the fourth connecting segment.

[0016] In one embodiment, reinforcing ribs are provided on the first folded edge and the second folded edge.

[0017] The present application also proposes a photovoltaic power station, comprising a photovoltaic component, a plurality of support components and a water tank as described above, wherein the water tank and the plurality of support components enclose a mounting position for mounting the photovoltaic component.

[0018] The present application also provides a photovoltaic power station, which is applied to a building, wherein the building includes a roof corner, the roof corner having a first inclined surface and a second inclined surface arranged at an angle, the photovoltaic power station including a first photovoltaic module, a second photovoltaic module, a first support assembly on which the first photovoltaic module is mounted, a second support assembly on which the second photovoltaic module is mounted, and the above-mentioned water tank;

[0019] The first support assembly is used to be installed on the first inclined surface of the roof ridge corner, and the second support assembly is used to be installed on the second inclined surface of the roof ridge corner;

[0020] At least part of the multiple bottom plate sections are bent toward the first inclined surface, and the first folded edge of the water trough is provided on the first supporting assembly and connected to the first photovoltaic assembly; the other parts of the multiple bottom plate sections are bent toward the second inclined surface, and the second folded edge of the water trough is provided on the second supporting assembly and connected to the second photovoltaic assembly.

[0021] Compared with the prior art, this application has the following beneficial effects:

[0022] The first folded edge, the bottom plate, and the second folded edge form a water trough. When used in the docking position between multiple photovoltaic modules, it can be used to receive and guide accumulated water to prevent water from seeping into the bottom of the photovoltaic modules, thereby optimizing the waterproof function.

[0023] A curved section is provided between two adjacent bottom plate sections.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments.

[0047] The existing water tank systems used in photovoltaic power stations, especially small photovoltaic power stations such as home photovoltaic power stations, need to set up common water tanks and ridge water tanks at the docking locations between multiple photovoltaic modules to achieve waterproofing. As the existing water tanks are not universal, it is necessary to process and produce different types of water tanks for common water tanks and ridge water tanks respectively, which increases the cost. Figures 1 to 13 This application proposes a water trough and a photovoltaic power station. By designing a curved section 120, the water trough is transformed into a required ordinary water trough or a roof ridge water trough, which can improve the versatility of the water trough and reduce the costs of processing and production, warehousing management, delivery and transportation, etc.

[0048] The water tank 100 of the embodiment of the present application is applied to a photovoltaic power station. Specifically, the water tank 100 includes a bottom plate 110, which includes a curved section 120 and multiple bottom plate sections 111. A curved section 120 is provided between two adjacent bottom plate sections 111. The curved section 120 is used to adjust the angle between the two adjacent bottom plate sections 111 when bending.

[0049] A first folded edge 141 and a second folded edge 142 are respectively provided on both sides of the bottom plate 110 . The first folded edge 141 , the bottom plate 110 and the second folded edge 142 form a water tank.

[0050] The first folded edge 141, the bottom plate 110 and the second folded edge 142 form a water trough. The bottom plate 110 is located at the bottom of the water trough 100 and is used to receive accumulated water. The first folded edge 141 and the second folded edge 142 are respectively arranged on both sides of the bottom plate 110 to construct the side walls of the water trough. When used in the docking position between multiple photovoltaic modules 220, the water trough 100 can receive and guide accumulated water to prevent water from seeping into the bottom of the photovoltaic module 220, thereby optimizing the waterproof function.

[0051] A bending section 120 is provided between two adjacent bottom plate sections 111. The bending section 120 refers to the portion of the bottom plate 110 that can bend at a certain position. This bendable portion is bent toward the position of the sink 100 for receiving and guiding accumulated water, and is specifically manifested as an arc-shaped protrusion, a bending angle, or other protruding structures. The bending section 120 is a bendable structure. By bending the bending section 120, the two bottom plate sections 111 on both sides of the bending section 120 can be bent relative to each other, so that the sink can be used as an ordinary sink when the bending section 120 is not bent; and by bending the bending section 120, the angle between the two adjacent bottom plate sections 111 is adjusted accordingly, so that the sink can be used as a required ridge sink, so as to realize the switching between ordinary sinks and ridge sinks to meet the needs of different scenarios. In this way, the versatility and flexibility of the sink can be improved, and the costs of processing and production, warehousing management, and delivery and transportation can be reduced. The functions of an ordinary sink and a ridge sink can be achieved by designing the curved section 120 alone. The overall structure is simple and convenient to produce, process, assemble and use.

[0052] In addition, a recessed section is formed on the lower surface of the base plate 110 at the position of the curved section 120. Specifically, the curved section 120 and the recessed section can be configured to fit together, so as to facilitate storage management, stacking multiple sinks 100 in sequence during delivery and transportation, and reduce the space occupied by the sinks 100.

[0053] The curved section design also alters stress distribution, concentrating stress within the sink 100 at the edge of the curved section 120. The curved section 120 acts as a reinforcing rib, enhancing the sink 100's bending resistance, strengthening its strength and stability, and improving its overall load-bearing capacity, preventing deformation due to accumulated water or other external loads.

[0054] The length direction of the sink 100 refers to the main extension direction of the sink, and the longest side is determined as the length of the sink 100. The flow direction of the water flowing into the sink 100 is consistent with the length direction of the sink 100; the width direction of the bottom plate segment 111 refers to the direction of the bottom plate segment 111 that is perpendicular to the length direction, and the width of the bottom plate segment 111 is determined as the distance between the two side edges of the bottom plate segment 111; the length of any bottom plate segment 111 is equal to the length of the sink 100, and the widths of any two bottom plate segments 111 can be the same or different.

[0055] In one embodiment, the curved section 120 extends along the length of the bottom plate section 111. The curved section 120, as a ribbed structure, can increase the rigidity and strength of the trough structure, reduce deformation or distortion of the trough 100 due to stress, and improve the lateral bending resistance of the trough 100 along its length.

[0056] In the embodiment of the present application, the number of the bottom plate segments 111 is two or more, and the number of the curved segments provided between two adjacent bottom plate segments 111 is correspondingly one or more.

[0057] Taking the example of two bottom plate segments 111, where the two bottom plate segments 111 include a first bottom plate segment 1111 and a second bottom plate segment 1112, a bending segment 120 is provided between the first bottom plate segment 1111 and the second bottom plate segment 1112, for adjusting the angle between the first bottom plate segment 1111 and the second bottom plate segment 1112 by bending the bending segment 120, so that the gutter 100 is suitable for different roof ridge angles or other installation surfaces with angles.

[0058] Taking the case where there are multiple bottom plate segments 111 as an example, a bending section is provided between any two adjacent bottom plate segments 111, which is used to bend the bottom plate 110 into a half trapezoid or other shapes according to actual needs, so as to be suitable for buildings with multiple corners or other application scenarios; the specific settings can be based on actual conditions and are not limited here.

[0059] Reference Figure 4 、 Figure 5 In one embodiment, the cross section of the curved section 120 is arc-shaped 121 .

[0060] Setting the cross-section of the curved section 120 to be in the shape of a “⌒” or other similar arc-shaped structures can facilitate water flow and reduce turbulence; it can also distribute stress more evenly, ensuring that the sink 100 is more structurally robust.

[0061] Reference Figure 6 、 Figure 7 In another embodiment, the curved section 120 includes a first plate section 1221 and a second plate section 1222 , and the first plate section 1221 and the second plate section 1222 are arranged at an angle.

[0062] It can be understood that the first plate segment 1221 and the second plate segment 1222 are two inclined plates arranged on the upper surface of the base plate 110. The curved section 120 is set to be an "Λ" or other similar sharp-angle structure formed by the first plate segment 1221 and the second plate segment 1222 at an angle, which can facilitate processing and manufacturing.

[0063] In one embodiment, the bottom plate segment 111 has a first end and a second end disposed opposite each other along its length. A water spout 130 is provided at the first end and / or the second end of each bottom plate segment 111. The water spout 130 guides the flow of water, ensuring that water flowing into the sink 100 is discharged smoothly, thereby reducing splashing and preventing clogging of the sink 100 due to failure to drain accumulated water and dirt in a timely manner.

[0064] The design of the water tongue 130 prevents water from seeping into the bottom of the trough and causing backflow. Because the curved section 120 of the trough 100 is bendable, the angle of the curved section 120 can be adjusted to allow for switching between a standard trough and a ridge trough. The water tongue 130 is positioned corresponding to the bottom plate section 111 to guide the water flow while preventing it from interfering with the adjustment of the curved section 120's angle.

[0065] When the water trough 100 is used as an ordinary horizontal water trough or a ridge water trough, the water tongue 130 of the water trough 100 is overlapped on a supporting component such as a vertical water trough 2301 for installing the photovoltaic component 220, or the water tongue 130 of the water trough 100 is used to overlap on an installation surface such as a ridge slope; it is used to guide the water flow through the water tongue 130 to avoid backflow.

[0066] To better guide the water flow, in one embodiment, the water tongue 130 is arranged to be inclined outward in a direction away from the bottom plate section 111 .

[0067] Optionally, the water tongue 130 can be set as a rectangular plate, an arc-shaped plate, etc., and the shape, outward inclination angle, etc. of the water tongue 130 can be the same or different. Specifically, the shape of the water tongue 130, the outward inclination angle of the water tongue 130, etc. can be set according to the maximum bendable angle of the bending section 120, which is not limited here.

[0068] In some embodiments of the present application, the curvature angle of the trough 100 can be determined based on the angle between two adjacent bottom plate sections 111 when the curved section 120 is bent. To prevent the bending angle adjustment of the trough 100 from being affected by the contact of the water tongues 130 between two adjacent bottom plate sections 111, when the water tongues 130 are curved, the curvature of the water tongues 130 can be adjusted based on actual conditions. Alternatively, the outward tilt angle of the water tongues 130 can be set so that the water tongues 130 of two adjacent bottom plate sections 111 are staggered when the curvature angle is adjusted.

[0069] In one embodiment, the base plate 110 has a mounting surface 1101 and a connecting surface 1102 disposed opposite to each other. The mounting surface 1101 is used to connect to an external building. The first folded edge 141 and the second folded edge 142 are disposed on both sides of the connecting surface 1102 .

[0070] It can be understood that the inclined surface close to the ridge 210, other installation surfaces or other surfaces of the building in the installed state is used as the installation surface 1101 of the base plate 110, and the other surface is used as the connecting surface 1102, and the first folded edge 141 and the second folded edge 142 are provided on the connecting surface 1102.

[0071] Optionally, the first folded edge 141 includes a first connecting segment 1411 and a second connecting segment 1412 connected as one body, wherein the second connecting segment 1412 is bent relative to the first connecting segment 1411. The second folded edge 142 includes a third connecting segment 1421 and a fourth connecting segment 1422 connected as one body, wherein the fourth connecting segment 1422 is bent relative to the third connecting segment 1421. The first connecting segment 1411 and the third connecting segment 1421 are disposed on opposite sides of the bottom plate 110.

[0072] The first connecting segment 1411 and the second connecting segment 1412 are arranged at an angle, and the bending direction of the second connecting segment 1412 is determined by the opening direction of the angle formed between the first connecting segment 1411 and the second connecting segment 1412. The third connecting segment 1421 and the fourth connecting segment 1422 are arranged at an angle, and the bending direction of the fourth connecting segment 1422 is determined by the opening direction of the angle formed between the third connecting segment 1421 and the fourth connecting segment 1422. Specifically, the angle between the first connecting segment 1411 and the second connecting segment 1412 can be set according to actual needs to determine the bending direction of the second connecting segment 1412; and the angle between the third connecting segment 1421 and the fourth connecting segment 1422 can be set to determine the bending direction of the fourth connecting segment 1422.

[0073] In the embodiment of the present application, when the bending direction of the second connecting section 1412 is the same as the bending direction of the fourth connecting section 1422, the following configuration is constructed: Figure 8 Specifically, the second connecting section 1412 is provided on a side of the first connecting section 1411 close to the second folded edge 142, and the fourth connecting section 1422 is provided on a side of the third connecting section 1421 away from the first folded edge 141; or, the second connecting section 1412 is provided on a side of the first connecting section 1411 away from the second folded edge 142, and the fourth connecting section 1422 is provided on a side of the third connecting section 1421 close to the first folded edge 141.

[0074] When the bending direction of the second connecting section 1412 is opposite to the bending direction of the fourth connecting section 1422, the following configuration is constructed: Figure 9 、 Figure 10 、 Figure 11Specifically, the second connecting section 1412 is provided on a side of the first connecting section 1411 close to the second folded edge 142, and the fourth connecting section 1422 is provided on a side of the third connecting section 1421 close to the first folded edge 141; alternatively, the second connecting section 1412 is provided on a side of the first connecting section 1411 away from the second folded edge 142, and the fourth connecting section 1422 is provided on a side of the third connecting section 1421 away from the first folded edge 141. When the bending direction of the second connecting section 1412 is opposite to the bending direction of the fourth connecting section 1422, the first folded edge 141 and the second folded edge 142 can be symmetrically provided on both sides of the bottom plate 110 by rationally planning the dimensions of the first connecting section 1411, the second connecting section 1412, the third connecting section 1421, and the fourth connecting section 1422, as well as the connection angles between the first connecting section 1411 and the second connecting section 1412, and the connection angles between the third connecting section 1421 and the fourth connecting section 1422. Among them, set as Figure 9 、 Figure 10 When the inner folding structure is shown, the waterproof and drainage capabilities can be optimized; Figure 11 When the outer folding structure is shown, it can be easily stacked for transportation.

[0075] In addition, the connection angles of the first connecting segment 1411, the third connecting segment 1421 and the bottom plate segment 111, the connection positions of the first connecting segment 1411, the third connecting segment 1421 and the bottom plate segment 111, etc. can be set according to actual needs and are not limited here.

[0076] Furthermore, the first connecting section 1411 and the second connecting section 1412 of the first folded edge 141 are perpendicular to each other and connected in an L-shape, and the third connecting section 1421 and the fourth connecting section 1422 of the second folded edge 142 are perpendicular to each other and connected in an L-shape. This facilitates production, processing, and transportation, improves waterproofing and drainage capabilities, and reduces the space occupied by the sink.

[0077] To further improve the bending rigidity of the water tank, in one embodiment, reinforcing ribs are provided on the first folded edge 141 and the second folded edge 142. Specifically, reinforcing ribs are provided on the first connecting segment 1411 and / or the second connecting segment 1412, the third connecting segment 1421 and / or the fourth connecting segment 1422.

[0078] Optionally, one or more reinforcing ribs 143 are provided on the side walls of the first connecting section 1411 and the third connecting section 1421, and each reinforcing rib 143 extends along the length direction of the water tank. When multiple reinforcing ribs 143 are provided, the multiple reinforcing ribs 143 are arranged at intervals.

[0079] By bending the curved section 120 in the middle of the gutter 100, the gutter 100 can be used as a ridge gutter for roof corners. In addition to using the water tongue 130 to guide the water flow, in some other optional embodiments of the present application, to further optimize the waterproof function, the water tongue 130 can also be installed on the first fold 141 and the second fold 142. The size of the water tongue 130 and the outward tilt angle of the water tongue 130 can be further adjusted according to the actual application scenario requirements.

[0080] It should be noted that in the embodiment of the present application, a first folded edge 141 and a second folded edge 142 are provided on both sides of the bottom plate 110, and the bottom plate 110, the first folded edge 141, and the second folded edge 142 are an integral structure with a non-adjustable connection angle. In other alternative embodiments, it is not ruled out that a curved section is provided corresponding to the first folded edge 141 (and / or the second folded edge 142), so as to construct the first folded edge 141 (and / or the second folded edge 142) with different desired angles by adjusting the bending angle of the curved section. The specific configuration can be based on actual needs and is not limited here.

[0081] The present application also proposes a photovoltaic power station, which includes a water tank 100. The specific structure of the water tank 100 refers to the above embodiment. Since the photovoltaic power station adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0082] The water tank 100 can be optionally used as a common water tank such as a horizontal water tank, or as a roof water tank.

[0083] As one of the implementation examples of this application, refer to Figure 1 , the water tank 100 is used as a horizontal water tank.

[0084] Specifically, the photovoltaic power station includes a photovoltaic assembly 220 , a plurality of support assemblies 230 and the water tank 100 as described in the above embodiment. The water tank 100 and the plurality of support assemblies 230 together form an installation position 233 for installing the photovoltaic assembly 220 .

[0085] The support assembly 230 can optionally be a vertical water trough 2301, with multiple vertical water troughs 2301 spaced apart. The ends of the water trough 100 in the aforementioned embodiment overlap the edges of two adjacent vertical water troughs 2301. When the water trough 100 is used as a horizontal water trough, the water tongues 130 at both ends of the water trough 100 overlap the vertical water troughs 2301 to guide the water flow through the water tongues 130 and prevent backflow.

[0086] Optionally, multiple water troughs 100 are provided, spaced apart to enclose mounting locations 233 between any two adjacent water troughs 100 and the two vertical troughs 2301. The dimensions of mounting locations 233 are adapted to the dimensions of photovoltaic modules 220. During heavy rainfall, water entering the water trough 100 through the water interface drains from both ends of the trough 100 into the vertical troughs 2301. The ribbed design of the curved section 120 improves the structural bending stiffness and stability, preventing drainage problems and the trough from bending toward the center due to excessive water accumulation, effectively enhancing waterproofing and drainage.

[0087] Optionally, when multiple mounting positions 233 are provided along the extension direction of the vertical water tank 2301, the first folded edge 141 of the water tank 100 between two adjacent mounting positions 233 is used to connect to the photovoltaic module 220 installed in one of the mounting positions 233, and the second folded edge 142 of the water tank 100 is used to connect to the photovoltaic module 220 installed in the other mounting position 233. When the photovoltaic module 220 is provided with a connecting frame, the photovoltaic module 220 is pressed against the water tank 100 by the connecting frame, and the connecting frame and the water tank 100 are connected and fixed using a component pressing block or the like.

[0088] It should be noted that the water tank 100 of this embodiment can be applied to a flat ground, a roof slope, etc., and is not limited here.

[0089] As the second implementation example of this application, refer to Figure 2 、 Figure 12 、 Figure 13 , the water tank 100 is used as a ridge water tank.

[0090] Specifically, the photovoltaic power station is applied to a building, which includes a roof corner, the roof corner having a first inclined surface 2101 and a second inclined surface 2102 set at an angle, and the photovoltaic power station includes a first photovoltaic component 2201, a second photovoltaic component 2202, a first support component 231 on which the first photovoltaic component 2201 is installed, a second support component 232 on which the second photovoltaic component 2202 is installed, and a water tank 100 as described in the above embodiment.

[0091] The first support assembly 231 is mounted on the first inclined surface 2101 of the roof ridge corner, and the second support assembly 232 is mounted on the second inclined surface 2102 of the roof ridge corner. The support assembly can optionally be a vertical gutter 2301, with the first support assembly 231 and the second support assembly 232 arranged at an angle, and the angle between the first support assembly 231 and the second support assembly 232 is equal to or close to the roof ridge angle.

[0092] At least part of the multiple bottom plate sections are bent toward the first inclined surface 2101, and the first folded edge of the water tank 100 is provided on the first support component 231 and connected to the first photovoltaic component 2201; other parts of the multiple bottom plate sections are bent toward the first inclined surface 2101, and the second folded edge of the water tank 100 is provided on the second support component 232 and connected to the second photovoltaic component 2202.

[0093] Taking the example of a bottom plate segment 111 comprising a first bottom plate segment 1111 and a second bottom plate segment 1112, with a curved segment 120 disposed between the first bottom plate segment 1111 and the second bottom plate segment 1112, the angle between the first bottom plate segment 1111 and the second bottom plate segment 1112 can be adjusted accordingly by bending the curved segment 120. Specifically, by bending the curved segment 120, the first bottom plate segment 1111 is bent toward the first inclined surface 2101, and the second bottom plate segment 1112 is bent toward the second inclined surface 2102, corresponding to the angle of the roof ridge angle, so that the angle between the first bottom plate segment 1111 and the second bottom plate segment 1112 matches the roof ridge angle. The first folded edge 141 of the water trough 100 overlaps the first support assembly 231 and is used to connect to the first photovoltaic assembly 2201 located at the top of the first inclined surface 2101. The second folded edge 142 of the water trough 100 overlaps the second support assembly 232 and is used to connect to the second photovoltaic assembly 2202 located at the top of the second inclined surface 2102. The bent water trough 100 is placed between the first photovoltaic assembly 2201 and the second photovoltaic assembly 2202 on both sides of the roof ridge 210 to collect rainwater in the gap between the first photovoltaic assembly 2201 and the second photovoltaic assembly 2202. Water entering the water trough 100 can be directly discharged from both ends of the water trough 100. The design of the curved section 120 not only improves the structural bending rigidity and stability, prevents poor drainage and prevents the water trough from bending toward the middle due to excessive water accumulation, thereby improving waterproofing and drainage, but also allows it to be adapted to roof ridge angles of different angles, effectively improving the versatility of the water trough 100.

[0094] In addition, in some optional embodiments, a ridge connector may be provided between the first support assembly 231 and the second support assembly 232. The ridge connector is used to connect the first support assembly 231 and the second support assembly 232, and the water tank 100 is mounted on the ridge connector. In order to guide the water flow through the water tongue 130 and avoid backflow, when the water tank 100 is used as a ridge tank, the water tongue 130 of the water tank 100 overlaps the first support assembly 231 and the second support assembly 232; or, the water tongue 130 of the water tank 100 overlaps the first inclined surface 2101 and the second inclined surface 2102; or, the water tongue 130 of the water tank 100 overlaps the ridge connector. The specific configuration may be based on actual conditions and is not limited here.

[0095] It should be noted that the water tank 100 of this embodiment can be applied to roof corners, other buildings with corners, etc., and is not limited here.
