Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and more specifically, to a photovoltaic floating body and a photovoltaic system. Background Technology

[0002] Currently, photovoltaic (PV) systems typically employ a "one-to-one" design for their floating PV units, meaning each floating unit corresponds to one PV module. To address the issue of shading by the PV modules, this type of system maintains a certain distance between the floating PV units to minimize the impact of shading on power generation efficiency. However, this type of PV system has some drawbacks:

[0003] (1) Large material consumption: Since each photovoltaic module requires an independent photovoltaic float support, the amount of float material consumed is large, which increases the overall cost of the photovoltaic system.

[0004] (2) Low installed capacity: The distance between photovoltaic floating bodies restricts the close arrangement of photovoltaic modules, thereby reducing the installed capacity per unit area.

[0005] (3) Large differences in tilt angle between photovoltaic modules: In order to adapt to different lighting conditions, the tilt angle between photovoltaic modules varies greatly, which not only increases the complexity of the design, but also leads to inconsistent performance between photovoltaic modules.

[0006] (4) Large amount of metal brackets: Traditional photovoltaic systems usually require a large number of metal brackets to fix photovoltaic modules, which not only increases material costs but also reduces construction efficiency.

[0007] Therefore, how to reduce the tilt angle difference of photovoltaic modules in a photovoltaic system has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide a photovoltaic floating body to reduce the tilt angle difference of photovoltaic modules in a photovoltaic system.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A photovoltaic floating body includes a floating body body, which has at least two weight-reducing holes and at least two sets of bracket mounting surfaces, which are used to support at least two sets of photovoltaic modules.

[0012] Optionally, in the above-mentioned photovoltaic floating body, at least two sets of mounting bosses are provided on the floating body body, and the side of each mounting boss facing away from the floating body body serves as the mounting surface of the bracket.

[0013] Optionally, in the above-mentioned photovoltaic floating body, the mounting bosses are three sets arranged at intervals along the first direction;

[0014] Along the first direction, the bracket mounting surface on the middle set of mounting bosses forms a mounting combination with the bracket mounting surfaces on the other two sets of mounting bosses, and the two mounting combinations support at least one set of photovoltaic modules.

[0015] Optionally, in the photovoltaic floating body described above, along the first direction, the extension lengths of the three sets of mounting bosses along the second direction decrease sequentially;

[0016] Alternatively, along the first direction, the extension length of the middle set of mounting bosses along the second direction is greater than the extension length of the other two sets of mounting bosses along the second direction.

[0017] Optionally, in the above-mentioned photovoltaic floating body, the mounting bosses are arranged in four groups at intervals along the first direction, namely, the first boss, the second boss, the third boss and the fourth boss.

[0018] The mounting surfaces of the first boss and the second boss form a mounting assembly, and the mounting surfaces of the third boss and the fourth boss form a mounting assembly. The two mounting assemblies support at least one set of photovoltaic modules respectively.

Detailed Implementation

[0061] The core of this invention lies in disclosing a photovoltaic floating body to reduce the tilt angle difference of photovoltaic modules in a photovoltaic system.

[0062] Another core aspect of this utility model is the disclosure of a photovoltaic system including the aforementioned photovoltaic float.

[0063] The embodiments will now be described with reference to the accompanying drawings. In the drawings, Figures 3-16 The floating body 100 in the middle is a one-piece structure. Figures 20-25 The floating body 100 is a split structure comprising multiple sub-bodies 110.

[0064] Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures illustrated in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features in these embodiments can be combined with each other.

[0065] Combination Figure 1 , Figure 3 and Figure 4 The photovoltaic floating body disclosed in this utility model includes a floating body body 100, which has at least two weight-reducing holes 101 and at least two sets of bracket mounting surfaces. The bracket mounting surfaces are used to support at least two sets of photovoltaic modules 300 through module brackets 310. Each set of bracket mounting surfaces includes at least two bracket mounting surfaces arranged at intervals along a third direction, which is perpendicular to the first direction.

[0066] Compared to existing technologies, the photovoltaic float disclosed in this utility model supports the photovoltaic module 300 through a bracket mounting surface. Simultaneously, a single photovoltaic float can support at least two sets of photovoltaic modules 300, reducing the number of photovoltaic floats in the photovoltaic system. This reduces connection nodes, improves the overall structural strength and stability of the float array, and optimizes the tilt angle differences of the photovoltaic modules in the photovoltaic system. Furthermore, it can shorten the spacing between the photovoltaic modules 300 in a row, effectively increasing the installed capacity. Supporting multiple photovoltaic modules 300 would result in an excessively large photovoltaic float; the inclusion of at least two weight-reducing holes 101 effectively reduces the mass of the photovoltaic float and lowers material costs.

[0067] For example, Figure 1 and Figure 2 The paper illustrates a technical solution in which two weight-reducing holes 101 are provided on the float body 100, and the two weight-reducing holes 101 are arranged sequentially along a first direction.

[0068] Specifically, the mounting surface of the bracket can protrude from the surface of the float body 100, be lower than the surface of the float body 100, or be parallel to the surface of the float body 100. The following description uses the example of the mounting surface protruding from the surface of the float body 100 as a specific embodiment. Specifically, at least two sets of mounting bosses 102 protrude from the float body 100. The side of each mounting boss 102 facing away from the float body 100 can serve as the aforementioned mounting surface of the bracket, and the component bracket 310 supports at least two sets of photovoltaic modules 300. The photovoltaic float disclosed in this utility model supports the photovoltaic modules 300 through the mounting bosses 102, thereby raising the photovoltaic modules 300, increasing the height of the photovoltaic modules 300 above the water, and thus reducing the probability of the photovoltaic modules 300 entering the water. The structure is simple and the cost is low.

[0069] Combination Figure 6 and Figure 7 The individual photovoltaic modules 300 on a photovoltaic floating body can be arranged in the same plane or in different planes; combined with Figure 9 and Figure 12 The installation tilt angles of the individual photovoltaic modules 300 on a photovoltaic float can be the same or different. The mounting surface of the bracket can be a plane or an inclined plane, and this utility model does not restrict the installation direction of the photovoltaic modules 300 relative to the float body 100.

[0070] For example, Figure 7 and Figure 8 The diagram illustrates a structural scheme in which multiple photovoltaic modules 300 are arranged on the same plane, which can effectively reduce the installation spacing of the photovoltaic modules 300 and increase the installed capacity.

[0071] Specifically, the present invention can increase the number of photovoltaic modules 300 that can be supported by extending the length of the floating body 100 in the first direction and increasing the number of mounting bosses 102.

[0072] In some embodiments, combined with Figure 1 , Figure 4 and Figure 5 The mounting bosses 102 are arranged in three sets at intervals along the first direction. Along the first direction, the bracket mounting surface of the middle set of mounting bosses 102 forms a mounting combination with the bracket mounting surfaces of the other two sets of mounting bosses 102. The two mounting combinations can support at least one set of photovoltaic modules 300 through the component bracket 310. That is, the middle set of mounting bosses 102 can be shared by different photovoltaic modules 300 to simplify the structure, reduce the volume of the floating body 100, and reduce costs.

[0073] Specifically, each set of mounting bosses 102 can be disposed on the same plane of the float body 100, and the extension length of each set of mounting bosses 102 along the second direction can be kept consistent. The second direction is perpendicular to both the first and third directions, thus enabling... Figure 13 and Figure 14 As shown, the photovoltaic modules 300 with a tilt angle of 0 are directly installed, or as... Figure 11 and Figure 12 As shown, the required installation tilt angle of the photovoltaic module 300 is formed by setting different sizes and / or numbers of module brackets 310 on the mounting surface of the bracket.

[0074] In some embodiments, along the first direction, the extension lengths of the three sets of mounting bosses 102 along the second direction decrease sequentially; or, along the first direction, the extension length of the middle set of mounting bosses 102 along the second direction is greater than the extension lengths of the other two sets of mounting bosses 102 along the second direction, so as to form a height difference through the different extension lengths of the mounting bosses 102 along the second direction, thereby meeting the installation tilt angle requirements of the photovoltaic module 300 to a certain extent, reducing the weight of the module bracket 310, reducing costs, and improving assembly efficiency.

[0075] Combination Figure 4 and Figure 5In some embodiments, the photovoltaic module 300 is mounted on the mounting boss 102 via a module bracket 310 and a pressure block 320. During assembly, the bolt holes of the module bracket 310 are first aligned with the pre-drilled bolt holes on the mounting boss 102 and connected with bolts. Then, the position of the module bracket 310 is adjusted according to installation requirements to ensure that the positions of the module brackets 310 on the same set of mounting bosses 102 are consistent. Next, two photovoltaic modules 300 are sequentially mounted on the module bracket 310, so that the lower flange of the aluminum frame of the photovoltaic module 300 is engaged in the rolled edge groove of the module bracket 310 and adjusted to an appropriate position. After the overall adjustment of the photovoltaic module 300 is completed, the pressure block 320 is used to press the photovoltaic module 300 firmly onto the module bracket 310, completing the assembly. The photovoltaic module 300 can also be mounted on the mounting boss 102 via a support rod. The specific structures of the support rod, module bracket 310, and pressure block 320 are existing technologies and will not be described in detail here.

[0076] In a specific embodiment of this utility model, the mounting bosses 102 are arranged in four groups at intervals along a first direction. The four groups of mounting bosses 102 are defined as a first boss, a second boss, a third boss, and a fourth boss along the first direction. The bracket mounting surfaces of the first boss and the second boss form a mounting combination, and the bracket mounting surfaces of the third boss and the fourth boss form a mounting combination. The two mounting combinations support at least one group of photovoltaic modules 300 through the component bracket 310.

[0077] Among them, combined Figure 13 and Figure 14 The first boss, the second boss, the third boss and the fourth boss can all be set on the same plane of the floating body 100, and the extension length of the first boss and the second boss along the second direction can be consistent, and the extension length of the third boss and the fourth boss along the second direction can be consistent, so that the photovoltaic module 300 can be arranged through the module bracket 310 or the photovoltaic module 300 can be directly set.

[0078] In some embodiments, combined with Figure 11 and Figure 12 The first, second, third, and fourth protrusions are all disposed on the same plane of the floating body 100. Along the first direction, the extension length of the first protrusion along the second direction is less than the extension length of the second protrusion along the second direction, and the extension length of the third protrusion along the second direction is less than the extension length of the fourth protrusion along the second direction, so that the two mounting assemblies are tilted in the same direction and the photovoltaic modules 300 are arranged therein. Alternatively, the extension length of the first protrusion along the second direction is less than the extension length of the second protrusion along the second direction, and the extension length of the fourth protrusion along the second direction is less than the extension length of the third protrusion along the second direction, so that the two mounting assemblies are tilted in opposite directions and the photovoltaic modules 300 are arranged therein.

[0079] Furthermore, combined Figure 15 and Figure 16 When the mounting bosses 102 are arranged in six or more groups at intervals along the first direction, three or more mounting combinations can be formed respectively. The specific arrangement is similar to the above-mentioned scheme of four groups of mounting bosses 102, and will not be described again here.

[0080] In a specific embodiment disclosed in this utility model, combined with Figures 17-19 The floating body 100 includes at least two sub-bodies 110, each sub-bodies 110 having a sub-bodies connecting portion. The sub-bodies 110 are connected via these connecting portions to form the floating body 100, thereby reducing the production cost of the large-volume floating body 100. Combined with... Figures 20-25 The structures of each sub-body 110 may be the same or different, and the number of sub-body 110 is not limited to two. For example, the floating body 100 can be... Figure 18 The two sub-body 110 are separated in the direction indicated by the middle arrow. The sub-body connecting part includes at least one of the first connecting ear 111 and the mounting groove 112. The two sub-body connecting parts can be directly connected by bolts, or by using an adapter to screw, snap, weld, etc.

[0081] To ensure reliable connections, each end of the floating body 100 along the first direction is provided with at least three second connecting lugs 103. The second connecting lugs 103 of different photovoltaic floating bodies are bolted together. By increasing the number of second connecting lugs 103, the number of connection points on the floating body 100 can be increased, thereby improving connection reliability. Furthermore, the structure of multiple second connecting lugs 103 can effectively increase the ultimate tensile force at a single anchoring point of the floating body 100, thereby reducing the construction workload of the floating body array; it can also improve the buoyancy transmission effect between photovoltaic floating bodies and optimize the tilt angle differences of the module rows.

[0082] The aforementioned float body 100 and mounting boss 102 can be an integral structure, and can be integrally manufactured by injection molding or other methods.

[0083] In some embodiments, combined with Figure 2 The photovoltaic float also includes a reinforcing member 200, whose two ends are bolted to the opposite sides of the weight-reducing hole 101 to further enhance the overall tensile strength of the photovoltaic float and improve the stability of the photovoltaic system, preventing deformation of the float body 100 when its size is too large. Specifically, the reinforcing member 200 can be rod-shaped and extends along a first direction or other directions; the weight-reducing hole 101 can be a closed structure or an open structure, and its shape is not limited to circular, semi-circular, and rectangular; combined with Figure 1 and Figure 19The opening position of the weight reduction hole 101 is not limited to the middle or edge position of the float body 100.

[0084] Combination Figure 26 The photovoltaic system disclosed in this utility model includes the aforementioned photovoltaic floating body, and therefore also possesses the aforementioned structure and beneficial effects. Other structures refer to the prior art and will not be described in detail here.

[0085] In a specific embodiment disclosed in this utility model, combined with Figure 27 Multiple photovoltaic floats are connected sequentially along a third direction to form a photovoltaic float column. A walkway float column is set between two adjacent photovoltaic float columns. The walkway float column is formed by multiple walkway floats 400 arranged sequentially along a third direction.

[0086] To further optimize the scheme, multiple photovoltaic floating columns can be arranged between two adjacent walkway floating columns to increase the installed capacity. In addition, connecting floating columns 500 can be set between two adjacent photovoltaic floating columns to avoid shading caused by the shadows of the front and rear rows of photovoltaic modules 300 when the photovoltaic system is working.

[0087] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Specific technical means in some embodiments may be incorporated, in whole or in part, into another embodiment without being explicitly excluded by another embodiment. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
