Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, and in particular to a flexible photovoltaic support and a photovoltaic installation foundation for a garbage landfill. Background Art

[0002] With the construction and development of cities, the amount of industrial and domestic waste is also increasing year by year. At present, landfill is the main method of waste disposal. After landfill, it is covered with protective film and planting soil to seal the site. However, the land is occupied for a long time after closure and the reuse rate is low. Therefore, it is proposed to study the use of closed landfills and other new energy projects such as photovoltaic power generation and wind power generation according to local conditions.

[0064] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0065] In the description of the utility model, it should be noted that, unless otherwise specified, "multiple" means two or more; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0066] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0067] Landfills may experience subsidence during the process of garbage degradation because of the garbage layer buried under them. When using such sites to build photovoltaic power stations, the difficulty of using photovoltaic brackets and foundation designs to adapt to foundation subsidence and to minimize the impact of foundation subsidence on the structure is also a problem. In addition, the anti-seepage protective layer on the surface of the landfill should also be protected from damage during the construction of photovoltaic power stations. Due to the poor geological conditions of landfill sites, low bearing capacity, uneven thickness distribution of garbage layers, and incomplete consolidation, before building photovoltaic power stations, in order to ensure that the foundation bearing capacity meets the design requirements and avoid uneven subsidence, the site needs to be pre-treated, and a certain thickness of plain soil is laid on the surface layer and compacted to ensure that a stable bearing layer can be provided for the construction of photovoltaic power stations.

[0068] In order to solve at least one of the above technical problems, the present utility model is proposed.

[0069] Combine the following Figures 1 to 12 , describing an embodiment of the utility model.

By adjusting the installation height of the two groups of ropes 2 located on the corresponding sides of the photovoltaic panel 100, the inclination angle of the photovoltaic panel 100 can be flexibly adjusted. Even if the photovoltaic bracket encounters settlement of the landfill foundation during use, the inclination angle of the photovoltaic panel 100 can be changed by changing the position of the fixing hole for the rope 2 to be at the optimal inclination angle for effectively utilizing solar energy, thereby ensuring power generation.

[0075] Specifically, a connecting steel beam 4 is provided between the two rows of columns 1 to further improve the support strength and structural stability. In addition, the ends of the ropes 2 are fixed to the columns 1 by P-type anchors 10, see Figure 3 .

[0080] The photovoltaic panel 100 is fixed by a pressing block, so that flexible installation between the photovoltaic panel 100 and the rope 2 is achieved, and the structure is simple and easy to install.

[0081] In one embodiment, the pressing assembly is detachably mounted on the rope 2 via a first U-shaped clip 8 .

[0082] The pressing assembly for fixing the photovoltaic panel 100 is connected to the rope 2 via a U-shaped card, so that the rope 2 can be slidably arranged in the U-shaped card, which is convenient for tensioning operation and can also facilitate the adjustment of the length of the rope 2 according to changes in height.

[0083] In one embodiment, the middle pressure block 32 includes:

[0084] The groove-shaped mounting portion 322 has a mounting hole on the bottom side for mounting a U-shaped card;

[0085] Two embedding portions are arranged on two wings of the groove-shaped mounting portion 322 and are used for embedding and supporting two adjacent photovoltaic panels 100 .

[0086] The grooved mounting portion 322 of the middle pressure block 32 is used to mount the U-shaped card to achieve connection with the rope 2; the embedded portion of the middle pressure block 32 is used to embed the photovoltaic panel 100 to achieve connection with the photovoltaic panel 100, and then install the photovoltaic panel 100 on the rope 2, which is convenient for adjusting the installation angle of the photovoltaic panel 100. Two embedded portions are provided to simultaneously fix two adjacent photovoltaic panels 100 in the photovoltaic array, reduce installation nodes, and improve installation convenience.

[0087] In one embodiment, the edge pressing block 31 comprises:

[0088] The L-shaped mounting portion 312 has a mounting hole on the bottom side for mounting a U-shaped card;

[0089] The embedding portion is arranged on the top of the L-shaped mounting portion 312 and is used for embedding and supporting the photovoltaic panel 100 .

[0090] The L-shaped mounting portion 312 of the edge pressure block 31 is used to install a U-shaped card to achieve connection with the rope 2; the embedding portion of the edge pressure block 31 is used to embed the photovoltaic panel 100 to achieve connection with the photovoltaic panel 100, and then install the photovoltaic panel 100 on the rope 2, which is convenient for adjusting the installation angle of the photovoltaic panel 100.

[0091] In one embodiment, the embedding portion is an embedding groove with an embedding opening on the side, and a connecting hole is opened on the bottom side of the embedding portion.

[0092] The embedding portion is an embedding groove with an embedding opening on the side, which is convenient for fixing the photovoltaic panel 100, and the clamping method has high reliability and stability.

[0093] In one embodiment, a second U-shaped clip 9 for the rope 2 to pass through is detachably provided in the fixing hole on the column 1 .

[0094] The rope 2 is arranged in the U-shaped card so that the rope 2 can be slidably arranged in the annular space surrounded by the U-shaped card, which is convenient for the tensioning operation of the rope 2 and can also conveniently adjust the length of the rope 2 according to the change of height.

[0095] In one embodiment, the rope 2 is a steel wire rope.

[0096] The steel wire rope has good structural strength, good load-bearing capacity, is easy to bend and deform, and also has a certain toughness.

[0097] According to an embodiment of the utility model, on the other hand, a photovoltaic installation foundation is also provided, including a plain fill layer 200, a concrete cushion layer 7, a pre-placed floating foundation and any of the above landfill flexible photovoltaic brackets arranged in sequence from bottom to top.

[0098] Because the photovoltaic installation foundation includes a landfill flexible photovoltaic support, it has the same effect as a landfill flexible photovoltaic support; in addition, the installation foundation adopts a pre-installed floating foundation, which can be pre-installed in advance, shortening the construction period and reducing damage to the anti-seepage protective layer.

[0099] In one embodiment, the pre-installed floating foundation includes a reinforced concrete foundation 6 , and an embedded part 5 is arranged between the reinforced concrete foundation 6 and the column 1 .

[0100] By using a reinforced concrete foundation 6 with a certain thickness, compared with the case where the thickness of the covering soil is relatively thin in the related art, the buried depth of the structure foundation is not limited, thereby improving the stability of the photovoltaic installation foundation.

[0101] like Figure 1-Figure 12As shown, the utility model provides a photovoltaic installation foundation. This solution adopts a prefabricated floating foundation to solve the technical difficulties of special geological technical design. The existing soil is leveled and compacted at the photovoltaic bracket installation location, and the concrete cushion layer 7 is poured in advance. At the same time, the reinforced concrete foundation 6 (concrete foundation pier) is prefabricated in batches in the factory. The embedded parts 5 are set on the top of the reinforced concrete foundation 6. After the prefabricated foundation maintenance meets the specification requirements, it is transported to the site and placed on the concrete cushion layer 7. Next, the upper photovoltaic bracket steel structure column 1 is installed. The column 1 is made of hot-rolled steel. The bottom plane of the column 1 connected to the embedded part 5 is milled flat in the factory and welded on the top surface of the embedded part 5 (embedded plate) on site. Bolt holes for fixing ropes 2 are opened on the flange plate on the top side of the column 1. Ropes 2 (steel wire ropes) are fixed to the column 1 through U-shaped clamps. When installing, the U-shaped clamps are passed through the bolt holes on the flange plate and temporarily fixed with bolts that are not tightened. Ropes 2 are temporarily in a loose state after passing through the U-shaped clamps. The length of ropes 2 between the columns 1 is adjusted so that the length of ropes 2 between each span is basically the same. The tensioning mechanical equipment is set on the side of the column 1 at the end, and tensioning begins. After tensioning, the rope body is in a straight state and has the rigidity to bear the weight of the photovoltaic panel 100. The photovoltaic panel 100 is fixed to the rope 2 by a pressure block. The metal pressure block is divided into a side pressure block 31 and a middle pressure block 32. The middle pressure block 32 fixes two photovoltaic panels 100 at the same time, and the side pressure block 31 fixes one photovoltaic panel 100. The middle pressure block 32 is provided with notches on both sides, and bolt holes (side mounting holes 3111, middle mounting holes 3211) are provided on the plate with notches. The frame of the photovoltaic panel 100 adopts a metal frame to prevent the photovoltaic glass plate from being damaged by external forces. Holes are provided on the metal frame, and bolts are used to pass through the metal frame of the photovoltaic panel 100 and the holes on the pressure block (side holes 3121, middle holes 3221) to fix the two together. The top of the column 1 is provided with a plurality of spare U-shaped card bolt holes arranged vertically at intervals. If the photovoltaic bracket encounters foundation settlement during use, resulting in foundation sinking, when the inclination angle of the photovoltaic panel 100 changes, the connection hole position of the U-shaped card and the column 1 can be adjusted and changed, so that the inclination angle of the photovoltaic panel 100 is restored to the original design position, and the photovoltaic panel 100 is always kept at a suitable inclination angle, ensuring the smooth operation of the photovoltaic power station.

[0102] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
