Technical Field
[0001] The utility model relates to the field of photovoltaic brackets, and more specifically, to an integrated three-stage adjustable photovoltaic bracket suitable for steep mountainous areas. Background Art
[0002] At present, the brackets commonly used in the field of mountain photovoltaic installation are usually two-stage adjustable photovoltaic brackets. In the case of photovoltaic installation on steep mountainous areas, when the height difference in the bracket installation area is large, the photovoltaic bracket cannot be installed normally due to the insufficient adjustable range of the bracket columns, which increases the difficulty of on-site construction. At the same time, the existing brackets require secondary assembly and processing of the bracket columns during the installation process, which increases the installation time and cost of on-site operations.

In the concrete cast-in-place pile 7, the fixed base 8 is to prevent the secondary column and the tertiary column from falling off from the bottom. The fixed base 8 is welded and fixed inside the primary column. The fixed base 8 is ten centimeters upward from the bottom of the primary column. The fixed base 8 is an annular steel sheet; a sealing rubber ring 4-1 is provided at the connection between the primary column 1 and the secondary column 2, and a sealing rubber ring 4-2 is provided at the connection between the secondary column 2 and the tertiary column 3. A clamp 10 is installed in the middle of the outer periphery of the primary column 1, and the two ends of the clamp 10 are respectively fixed to one end of the rear diagonal brace 11 and the front diagonal brace 12, and the two ends of the diagonal brace 14 are respectively fixed to the other end of the rear diagonal brace 11 and the front diagonal brace 12; one end of the connecting piece 13 is hinged to the top end of the tertiary column 3, and the other end of the connecting piece 13 is connected to the middle of the bottom surface of the diagonal brace 14.
[0005] The photovoltaic panels are installed in the installation plane formed by the diagonal braces 14 and the purlins.
[0006] The diameters of the limiting base 1 6 - 1 and the limiting base 2 6 - 2 are respectively larger than the diameters of the secondary column 2 and the tertiary column 3 .
[0007] The five photovoltaic brackets mentioned above constitute a photovoltaic array unit.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] 1. While keeping the materials of the existing photovoltaic support columns unchanged, the utility model re-divides the existing two-stage adjustable column support into a three-stage adjustable column support, and adds an adjustable column structure. Compared with the existing two-stage column support, the vertical height adjustability of the photovoltaic support is effectively improved, which can solve the problem of excessive height difference between individual brackets in each bracket group when installing photovoltaic brackets on steep mountainous areas.
[0010] 2. In the construction site area, the existing photovoltaic support columns need to be assembled for the second time. The one-piece column structure of the utility model integrates three-section column structures and two parts of sealing rubber rings, which not only facilitates the material transportation process, but also saves considerable time cost for on-site construction assembly.

[0017] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the utility model. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the utility model. The terms used herein in the specification of the utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model.
[0018] like Figure 1 As shown, the utility model includes a primary column 1, a secondary column 2, a tertiary column 3, a sealing rubber ring 1 4-1, a sealing rubber ring 2 4-2, a through screw 5, a limit base 1 6-1, a limit base 2 6-2, a concrete cast pile 7, a fixed base 8, a hoop 10, a rear diagonal brace 11, a front diagonal brace 12, a connecting piece 13 and a diagonal brace 14; the secondary column 2 is inserted into the column body of the primary column 1 and is fixed by the through screw 1 5-1, and the tertiary column 3 is inserted into the column body of the secondary column 2 and is fixed by the through screw 2 5-2; the bottom surfaces of the secondary column 2 and the tertiary column 3 are respectively fixed with the limit base 1 6-1 and the limit base 2 6-2, wherein the limit base 6 is used to prevent the secondary column 2 and the tertiary column 3 from detaching from the column structure of the photovoltaic bracket during transportation and construction, the primary column 1 is inserted into the concrete cast pile 7, and the fixed bottom The seat 8 is to prevent the secondary column and the tertiary column from falling off from the bottom. The fixed base 8 is welded and fixed inside the primary column. The fixed base 8 is ten centimeters upward from the bottom of the primary column. The fixed base 8 is an annular steel sheet. A sealing rubber ring 4-1 is set at the connection between the primary column 1 and the secondary column 2, and a sealing rubber ring 4-2 is set at the connection between the secondary column 2 and the tertiary column 3. The function of the sealing rubber ring is to prevent pollutants such as rainwater and dust from entering the column to pollute and corrode it. A clamp 10 is installed in the middle of the outer periphery of the primary column 1. The two ends of the clamp 10 are respectively fixed to one end of the rear diagonal brace 11 and the front diagonal brace 12, and the two ends of the diagonal brace 14 are respectively fixed to the other end of the rear diagonal brace 11 and the front diagonal brace 12; one end of the connecting piece 13 is hinged to the top of the tertiary column 3, and the other end of the connecting piece 13 is connected to the middle of the bottom surface of the diagonal brace 14.
[0019] The photovoltaic panel 15 is installed in the installation plane formed by the diagonal braces 14 and the purlins.
[0020] Figure 2and Figure 3 The following is a detailed description of the two working adjustment modes of the integrated three-stage adjustable photovoltaic bracket. Figure 2 The working mode achieves a certain range of column height adjustment by hiding the primary column 1 in the secondary column 2. Figure 3 In the working mode, the primary column 1 is hidden in the secondary column 2, and the secondary column 2 is hidden in the tertiary column 3. The above method realizes the maximum adjustment limit of a single photovoltaic column.
[0021] like Figure 4 As shown, the primary column 1 is reliably connected to the connecting piece 13, which can be used to adjust the angle of the photovoltaic panel 15. The diagonal brace 14 is reliably connected to the front diagonal brace 11, the rear diagonal brace 12 and the connecting piece 13 to form a working plane of the photovoltaic panel 15. The photovoltaic panel 15 is connected to the diagonal brace 14 to form a single photovoltaic power generation unit.
[0022] A single photovoltaic array unit consists of five photovoltaic brackets, as mentioned above Figure 5 As shown in the figure, when the photovoltaic array units are arranged on a mountainous surface with a gentle slope and a small drop, the height adjustment of the columns of a single photovoltaic bracket remains consistent. Figure 6 As shown. First, the large slope of the mountain will increase the front-to-back height difference of the entire photovoltaic array. Secondly, there are mostly large rock blocks in mountainous areas, which makes the casting surface of the photovoltaic array rugged and uneven, which can easily cause inconsistent drilling depths in the early stage, further increasing the front-to-back height difference of the photovoltaic bracket in the photovoltaic array. Therefore, the integrated three-stage adjustable photovoltaic bracket proposed by the utility model can meet the problem of excessive front-to-back height difference of the photovoltaic array in the above-mentioned conditions.
[0023] The utility model is aimed at photovoltaic installation projects on steep mountain slopes. Due to the large mountain slope, the front-to-back height difference between the entire photovoltaic array will be increased. Secondly, there are mostly large rock blocks in mountainous areas, which makes the casting surface of the photovoltaic array rugged and uneven. It is easy to cause inconsistent drilling depth in the early stage, further increasing the front-to-back height difference of the photovoltaic bracket in the photovoltaic array. The utility model's integrated three-stage adjustable photovoltaic bracket can solve the problem of excessive front-to-back height difference of the photovoltaic array. For the current photovoltaic installation site, the utility model's integrated photovoltaic bracket saves considerable time costs and human and material resources for material transportation and subsequent on-site bracket construction and assembly.
[0024] The utility model discloses an integrated bracket structure. The current photovoltaic bracket column structure includes multi-level columns that need to be transported in batches, and secondary assembly of the column main structure is required at the construction site. To solve the above problems, the utility model discloses an integrated bracket structure that integrates three groups of column structures and two groups of sealing rubber rings into a single bracket structure.
[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
