Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a photovoltaic bracket used in a water plant. Background Art

[0002] Photovoltaic panels are a type of direct solar power generation device, mainly made of silicon semiconductor materials, which converts light energy into electrical energy, thereby facilitating the collection and use of clean energy. Since water plants are large energy consumers and have a large amount of available space, building photovoltaic systems in water plants is currently a hot topic and a key focus.

[0003] As a structure that supports photovoltaic panels, photovoltaic brackets affect the construction of photovoltaic systems to a certain extent. At present, there are three types of photovoltaic system construction forms, namely portal steel frame system, grid system and flexible bracket system. The above three photovoltaic bracket systems are all constructed outside the structure pool. It is necessary to lay the foundation first, then set up columns, and erect keels, beams and other structures. They have the following shortcomings:

[0043] Please refer to Figures 1 to 6 A photovoltaic bracket for a water plant provided in an embodiment of the present application includes a main keel 1, a secondary keel 2 and a mounting support 3; multiple main keels 1 are arranged in parallel, and multiple mounting supports 3 are fixedly connected to the inner wall of a water pool 91, and the distribution positions of the mounting supports 3 correspond to the positions of the two ends of the main keel 1, and the two ends of the main keel 1 are fixedly connected to the mounting supports 3; multiple secondary keels 2 are arranged in parallel, and the secondary keels 2 are perpendicular to the main keels 1, and the secondary keels 3 are fixedly connected to the upper side of the main keel 1, and multiple fixing clips 4 for clamping the ends of the photovoltaic panels 95 are provided on the secondary keels 3.

[0044] In the above scheme, the mounting support 3 can be fixedly connected to the inner wall of the pool 91 by mechanical anchor bolts, and the two ends of the main keel 1 are fixedly connected to the mounting support 3. Multiple secondary keels 2 are fixedly connected to the upper side of the main keel 1, and the multiple secondary keels 2 form a cross grid structure with the multiple main keels 1. Each secondary keel 2 can be divided into multiple sections according to the length, and multiple sections can be arranged in the same direction according to the construction area to form a secondary keel 2. A fixing card 4 is installed on the secondary keel 2, and the fixing cards 4 on the two adjacent secondary keels 2 are used to support and fix the two ends of the photovoltaic panel 95. The photovoltaic bracket is directly installed on the wall of the pool of the structure, without the need for civil construction outside the pool, and can accurately control the construction area, and has no effect on the operation of the pool when it is full of water, meeting the requirements of the water plant without stopping work, and the overall structure is simple, saving the cost of building the photovoltaic system.

[0045] According to some embodiments of the present application, both ends of each main keel 1 are detachably connected to the mounting bracket 3 via a first connecting member 5, each secondary keel 2 is detachably connected to the main keel 1 via a second connecting member 6, and the fixing card 4 is detachably connected to the secondary keel 2. Since the main keel, secondary keel and fixing card in the photovoltaic bracket are all installed and fixed in a detachable manner, the installation and disassembly of the entire photovoltaic bracket are flexible, which is convenient for early installation and later maintenance, and is convenient for future upgrading and transformation of the water plant; at the same time, modular accessories can be realized, and accessories of different specifications can be matched according to different spans, and the entire installation process does not require welding, cutting and other operations.

[0046] According to some embodiments of the present application, a third connecting member 7 is provided at the middle of the lower side of the main keel 1, and the third connecting member 7 is used to install the anti-hanging film 94. The photovoltaic bracket is provided with a third connecting member at the middle of the lower side of the main keel, and the anti-hanging film of the pool can be installed through the third connecting member. In this way, a set of bracket systems can be used to install the anti-hanging film and build the photovoltaic system, which is conducive to saving costs and improving aesthetics.

[0047] According to some embodiments of the present application, a slide groove 21 is provided at the top of the secondary keel 2, and the slide groove 21 extends along the length direction of the secondary keel 2, and the fixing card 4 is installed and fixed to the top of the secondary keel 2 by a fastener 22 placed in the slide groove 21. By reserving a photovoltaic installation slide groove at the top of the secondary keel and using bolt connection to reduce the construction period, the installation requirements of different photovoltaic panel sizes can also be met. Specifically, the slide groove 21 can be a T-slot provided at the top of the secondary keel 2, and the position of the fastener 22 along the length direction of the slide groove 21 is adjustable; the fastener 22 includes a bolt and a nut block adapted to the bolt, wherein the bolt is provided in the slide groove 21, the nut block is sleeved on the bolt and is located in the secondary keel 2, and the fixing card 4 can be installed on the top of the secondary keel 2 by the fastener 22.

[0048] According to some embodiments of the present application, the fixing card 4 has two card slots 41, and the opening directions of the two card slots 41 are opposite to each other, and the width of the card slot 41 is adapted to the thickness of the end of the photovoltaic panel 95. When installing the photovoltaic panel, the two ends of the photovoltaic panel 95 are placed in the card slots 41 on the two opposite fixing cards 4 on the two adjacent secondary keels 2, and then the fixing card 4 is fastened to the secondary keel 2. The installation and positioning of the photovoltaic panel on the bracket is achieved by limiting the end of the photovoltaic panel with the card slot.

[0049] According to some embodiments of the present application, the first connector 5 has a variety of different height specifications. By using first connectors of different heights, the main keel and the secondary keel can be tilted to form different angles with the ground, so as to achieve the best photovoltaic panel installation angle in different regions and meet the photovoltaic panel lighting requirements. For example, first connectors of different heights are used at both ends of the same main keel; or first connectors of the same height are used at both ends of the same main keel, while the heights of the first connectors used by adjacent different main keels gradually increase, so that the tilted installation of photovoltaic panels can be achieved.

[0050] According to some embodiments of the present application, the second connector 6 has a plurality of different height specifications. Since each secondary keel is connected to the main keel through a plurality of second connectors, similarly, by using second connectors of different heights, the secondary keel can be tilted to form different angles with the ground, thereby achieving the best photovoltaic panel installation angle in different regions.

[0051] According to some embodiments of the present application, the photovoltaic support for the water plant further includes a steel insert 8, and both ends of each main keel 1 are detachably connected to the mounting support 3 through the steel insert 8. Specifically, the lower end of the steel insert 8 has a connecting plate, which is bolted to the mounting support 3 through the connecting plate, and the upper end of the steel insert 8 is inserted into the through groove of the main keel 1. Of course, other forms of steel inserts 8 can also be used as long as they have a certain height.

[0052] The height of the photovoltaic arrangement can be increased by using the steel insert 8, which is close to the height of the existing railing 92 at the edge of the pool 91, so that the photovoltaic bracket can be used as part of the guardrail. By integrating the structure with the photovoltaic bracket, the bracket system can be directly used as a guardrail or a lifting frame for daily water treatment equipment, providing more functions.

[0053] According to some embodiments of the present application, the main keel 1 and the secondary keel 2 are basalt fiber composite profiles. The use of basalt fiber main keels and secondary keels, under the premise of meeting the use requirements, their weight is greatly reduced compared to steel, that is, the weight of the entire photovoltaic bracket is reduced, which is conducive to reducing the stress on the pool wall.

[0054] Of course, it is understandable that the main keel 1 and the secondary keel 2 can also be light steel structure keels, but their weight will be much greater than that of basalt fiber keels, so the force on the pool wall will also increase.

[0055] According to some embodiments of the present application, the mounting bracket 3, the first connecting member 5, the second connecting member 6 and the third connecting member 7 are all made of weathering steel. The mounting bracket and all connecting members are made of weathering steel, which can improve the anti-corrosion performance.

[0056] The photovoltaic system is constructed as follows: 1) Use mechanical anchor bolts to connect the mounting bracket 3 to the inner wall of the pool 91; 2) Use the first connecting piece 5 (including a stainless steel bolt assembly) to connect the two ends of the main keel 1 to the mounting bracket 3; 3) Use the second connecting piece 6 (including a stainless steel bolt assembly) to connect the secondary keel 2 to the main keel 1; 4) Install the anti-hanging membrane 94 (PVDF membrane), use the third connecting piece 7 (including a stainless steel bolt assembly) to connect the anti-hanging membrane 94 to the main keel 1, and fix the anti-hanging membrane 94 on the pool walls on both sides; 5) Install the photovoltaic panel 95.

[0057] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
