Description

Technical Field

[0001] This utility model relates to the field of installation pile technology, and in particular to an installation pile for photovoltaic power generation. Background Technology

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. It mainly consists of three parts: solar panels, controllers, and inverters. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as power controllers, a photovoltaic power generation device is formed. Since solar panels are installed outdoors, in order to ensure stability, the solar panel supports are fixed to the ground by mounting piles.

[0003] However, in the existing technology, most of the foundation piles used to fix the solar panel brackets are directly cast in concrete. During the casting process, the solar panel brackets are fixed by pre-drilling fixing holes or using screws. However, whether it is fixing holes or screws, they can only be fixed by threads, which results in limited fixing strength during use and greatly reduces the fixing firmness of the foundation piles. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of limited fixing firmness of existing photovoltaic power generation installation piles in the prior art, and to propose a photovoltaic power generation installation pile.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: including a connecting base and a support base plate, wherein a limiting side plate is symmetrically fixed on the top surface of the connecting base, and a plurality of fixing holes are equidistantly opened on the top surface of the limiting side plate, and a fixing screw tube is pre-embedded and fixed inside the connecting base below each fixing hole, and a plurality of limiting protrusions are equidistantly fixed on the outer surface of the fixing screw tube, and a fixing screw hole that mates with the fixing hole is opened inside each fixing screw tube;

[0006] The top surface of the connecting base is fitted with a bracket base plate, and the two sides of the bracket base plate are inserted into the limiting side plate. An mounting plate is provided above the bracket base plate. A bracket column is symmetrically fixed on the top surface of the bracket base plate, and the top surface of the bracket column is fixed to the bottom surface of the mounting plate. Each side of the bracket base plate has another fixing hole that matches the fixing hole in the limiting side plate.

[0007] Preferably, the bottom surface of the connecting base is provided with a limiting connecting plate, and a plurality of reinforcing piles are symmetrically and equidistantly arranged on the bottom surface of the limiting connecting plate. The limiting connecting plate and the reinforcing piles are integrally cast with the connecting base, and the length of the limiting connecting plate is greater than the length of the connecting base.

[0008] Preferably, the height of the fixing screw tube is less than the height inside the connecting base, the top surface of the fixing screw tube is fixed with a positioning plate, and the top surface of the positioning plate is flush with the top surface of the connecting base. The positioning plate has a fixing screw hole that mates with the fixing screw tube.

[0009] Preferably, each of the limiting protrusions is configured as a tapered shape with the narrow end pointing downwards, and each of the fixing screw, limiting protrusion and positioning plate is vertically pre-embedded and fixed inside the connecting base.

[0010] Preferably, each of the limiting side plates is configured as an inverted "L" shape, the thickness of the bracket base plate is equal to the thickness between the inner bottom surface of the limiting side plate and the top surface of the connecting base, and the width of the limiting side plate is equal to the width of the connecting base.

[0011] Preferably, a positioning protrusion is cast and fixed on the top surface of the connecting base between the two limiting side plates, and the thickness of the positioning protrusion is equal to the thickness of the bracket base plate. A positioning groove that mates with the positioning protrusion is provided in the middle of the side of the bracket base plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the limiting side plates on both sides can limit the bottom plate of the bracket during the installation of the bracket. With the help of multiple fixing bolts, the connection between the bracket and the foundation pile is more firm and stable. This solves the problem of limited fixing firmness of existing photovoltaic power generation installation foundation piles during use, and greatly improves the fixing firmness of the foundation pile, thereby ensuring the stability of the solar panel outdoors.

[0014] 2. In this utility model, the connection between the fixed screw tube and the connecting base is increased by multiple limiting protrusions on the fixed screw tube. The limiting connecting plate at the bottom can increase the connection between the connecting base and the ground, thereby further improving the stability when the foundation pile is installed. In addition, the positioning protrusions and positioning slots cooperate to quickly align the bottom plate of the bracket with the top surface of the connecting base when fixing.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] like Figure 1-4 As shown, this utility model provides a photovoltaic power generation installation pile, including a connecting base 1 and a support base plate 11. A limiting connecting plate 2 is provided on the bottom surface of the connecting base 1. A plurality of reinforcing piles 3 are symmetrically and equidistantly arranged on the bottom surface of the limiting connecting plate 2. The limiting connecting plate 2 and the reinforcing piles 3 are integrally cast with the connecting base 1. The length of the limiting connecting plate 2 is greater than the length of the connecting base 1. A limiting side plate 8 is symmetrically fixed on the top surface of the connecting base 1, and a plurality of fixing holes 9 are equidistantly opened on the top surface of the limiting side plate 8. A fixing screw tube 4 is pre-embedded and fixed inside the connecting base 1 below each fixing hole 9, and a plurality of limiting protrusions 5 are equidistantly fixed on the outer surface of the fixing screw tube 4. A fixing screw hole 7 that mates with the fixing hole 9 is opened inside each fixing screw tube 4.

[0024] The specific settings and functions of this embodiment are described below: The height of the fixed screw tube 4 is less than the internal height of the connecting base 1. The top surface of the fixed screw tube 4 is fixed with a positioning plate 6, and the top surface of the positioning plate 6 is flush with the top surface of the connecting base 1. This facilitates the vertical placement of the fixed screw tube 4 during pre-embedding and makes it easy to remove the fixed screw tube 4 during pre-embedding. The positioning plate 6 has a fixing screw hole 7 that mates with the fixed screw tube 4, preventing the positioning plate 6 from affecting the normal connection of the fixed screw tube 4. Each limiting protrusion 5 is set as a tapered shape with the narrow end pointing downwards, which facilitates the insertion of the fixed screw tube 4 into the undried concrete and also facilitates the limiting protrusion 5 to limit and reinforce the fixed screw tube 4. Each fixed screw tube 4, limiting protrusion 5, and positioning plate 6 are vertically pre-embedded and fixed inside the connecting base 1, ensuring that the bolt is screwed into the fixing screw hole 7 after passing through the fixing hole 9.

[0025] Example 2

[0026] like Figure 1-4 As shown, a bracket base plate 11 is attached to the top surface of the connecting base 1, and the two sides of the bracket base plate 11 are inserted into the limiting side plate 8. An mounting plate 13 is provided above the bracket base plate 11. A bracket column 12 is symmetrically fixed to the top surface of the bracket base plate 11, and the top surfaces of the bracket columns 12 are all fixed to the bottom surface of the mounting plate 13. Another fixing hole 9 is opened on both sides of the bracket base plate 11, which matches the fixing hole 9 in the limiting side plate 8.

[0027] The overall effect of this embodiment is that each limiting side plate 8 is set as an inverted "L" shape. The thickness of the bracket base plate 11 is equal to the thickness between the inner bottom surface of the limiting side plate 8 and the top surface of the connecting base 1, and the width of the limiting side plate 8 is equal to the width of the connecting base 1. The limiting side plate 8 limits the bracket base plate 11, so that the limiting side plate 8 can provide a fixing force to the bracket base plate 11. At the same time, when the bracket base plate 11 is tilted, it can provide a supporting force to the bracket base plate 11. The top surface of the connecting base 1 between the two limiting side plates 8 is cast and fixed with a positioning protrusion 10, and the thickness of the positioning protrusion 10 is equal to the thickness of the bracket base plate 11. The middle of the side of the bracket base plate 11 is provided with a positioning groove 14 that cooperates with the positioning protrusion 10. Through the cooperation of the positioning protrusion 10 and the positioning groove 14, the bracket base plate 11 and the connecting base 1, as well as the fixing holes 9 inside the bracket base plate 11 and the limiting side plate 8, can be quickly aligned.

[0028] The usage and working principle of this device are as follows: When constructing the foundation piles, the connecting base 1, the limiting connecting plate 2, and the reinforcing pile 3 are cast from bottom to top using a precast slab casting method. After casting is completed and the top surface of the connecting base 1 is horizontal, the fixing screws 4 are inserted into the connecting base 1 one by one according to the positioning. The limiting side plate 8 is then cast using a precast slab. After the concrete dries and solidifies, the precast slabs are removed one by one. After removal, the bracket base plate 11 is inserted into the top surface of the connecting base 1 between the two limiting side plates 8 along the end away from the positioning protrusion 10. This allows the bracket base plate 11 to engage with the positioning protrusion 10 through the positioning slot 14, thereby aligning the fixing hole 9 and the fixing screw hole 7 one by one. After alignment, the bracket base plate 11 is fixed by passing the fixing bolt through the fixing hole 9 and then screwing it into the fixing screw hole 7. Finally, the solar panel is installed on the top surface of the mounting plate 13 using fasteners.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
