Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic construction, and in particular to a photovoltaic bracket for a fish pond bank and an installation and deployment method thereof. Background Art

[0002] With the continuous development and expansion of the photovoltaic industry in China, the types of land that can be used to build photovoltaic power stations are currently limited, and there are more and more projects using fish ponds for fish-light complementary photovoltaic power stations. In order to further improve the efficiency of land use in restricted areas, maximize the use of existing sites and increase the design capacity of project layout, it is necessary not only to build photovoltaic power generation systems on the surface of fish ponds, but also to consider the use of pond embankments between fish ponds and use the embankments to design the layout of photovoltaic brackets. Since the width of fish pond embankments is often limited, conventional design schemes are currently adopted. Modeling is required to ensure that a certain distance must be maintained between the front and rear rows of photovoltaic brackets to avoid shadows. At the same time, the traditional bracket structure type is a unified small bracket structure, and a certain distance must be left between adjacent brackets in the same row. When the length direction of the fish pond embankment is certain, the arrangement of small bracket structures and the spacing between adjacent brackets in the same row will cause too much land waste and low land utilization efficiency.

[0003] Therefore, it is of great practical significance to develop a photovoltaic support for fish pond banks that is particularly suitable for use in narrow spaces and an application method thereof. Summary of the invention

[0004] Due to the above-mentioned defects in the prior art, the present invention provides a photovoltaic bracket for the bank of a fish pond that is particularly suitable for use in a narrow space, and an application method thereof. The bracket structure is optimized and designed for a fish-photovoltaic complementary photovoltaic project to reduce the shading effect of the front and rear rows of brackets and increase the number of photovoltaic arrays, so as to overcome the defects of the traditional design method that limits the arrangement of brackets in the length and width directions of the fish pond.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A photovoltaic support for a fish pond bank, comprising an upper clamp, a lower clamp, a vertical column I, a vertical column II, an inclined beam, a front support rod and a rear support rod;

The vertical column I and the vertical column II are provided with at least two vertical column through holes arranged along the length direction. Both ends of the vertical column I and the vertical column II are fixed on the upper hoop and the lower hoop by bolts.

[0008] The two ends of one upper hoop half ring of the upper hoop are provided with strut fixing holes, one end of the front strut and the rear strut are fixed to the upper hoop half ring through strut fixing bolts, and the other end of the front strut and the rear strut are fixed to the inclined beam.

[0009] The photovoltaic bracket for the bank of a fish pond of the present invention has a reasonable structural design. The photovoltaic bracket is fixed to the prestressed concrete pipe pile by upper and lower clamps, and the inclined beam is fixed to the upper clamp by front and rear support rods. At the same time, the upper and lower clamps are also connected together by vertically arranged vertical columns I and II, which can ensure that the bracket is firmly fixed on the prestressed concrete pipe pile.

It has a simple structure, occupies a small space, is convenient to adjust and has multiple adjustment dimensions. It is particularly suitable for narrow spaces (fish pond banks), can maximize the use of the width of the fish pond bank, improve land utilization, utilize the length of the bank, and increase the number of arrays, and has great application prospects.

[0010] As the preferred technical solution:

[0013] The upper hoop half ring II includes a half ring part II and fixed ears II located on both sides of the half ring part II. The length of the fixed ears II is greater than the fixed ears I. The fixed ears II are provided with upper hoop half ring II strut fixing holes and half ring through holes II matching the half ring through holes I. The upper hoop half ring II strut fixing holes are located at the part where the fixed ears II exceed the fixed ears I. Integrating the strut fixing holes on the upper hoop half ring greatly simplifies the structural design of the strut connection.

[0014] As described above, a photovoltaic bracket for a fish pond bank, wherein the connection portion between the semi-ring portion I and the fixed ear portion I is provided with an upper hoop semi-ring I stiffening plate to ensure its structural strength;

[0015] An upper hoop semi-ring II stiffening plate is provided at the connection portion between the semi-ring portion II and the fixed ear portion II to ensure its structural strength.

[0016] As described above, a photovoltaic bracket for the bank of a fish pond, a limiting angle steel connecting the vertical column I and the vertical column II and arranged horizontally is provided between the two, and the limiting angle steel is located above the top of the prestressed concrete pipe pile, which can prevent the photovoltaic bracket from being subjected to excessive force and the upper and lower clamps from sliding relative to the prestressed concrete pipe pile.

[0017] In the photovoltaic support for the bank of a fish pond as described above, the tops of the vertical columns I and II are fixed to the inclined beams by bolts, which can ensure that the inclined beams and the photovoltaic support are securely fixed.

[0019] One side of the L-shaped adapter plate is fixed to the inclined beam by bolts, and the other side is fixed to the purlin bolts;

[0020] The photovoltaic modules are fixed to the purlins with bolts.

[0021] In the photovoltaic bracket for the bank of a fish pond as described above, the photovoltaic component is pressed by the photovoltaic component pressing block and the bolts for fixing the photovoltaic component pass through the photovoltaic component pressing block and the photovoltaic component in sequence and are threadedly connected with the special-shaped nut and the locking nut respectively. Double fixation is achieved by the special-shaped nut and the locking nut, which can ensure reliable fixation of the photovoltaic component.

[0022] In addition, the present invention also provides a method for installing and laying out a photovoltaic support on a fish pond bank as described above, comprising the following steps:

[0023] (1) Determine the number of rows, spacing and height of the photovoltaic brackets on the fish pond embankment according to the actual situation of the fish pond embankment to be laid out;

[0024] (2) Determine the azimuth angle of the photovoltaic support and the inclination angle of the photovoltaic module on the fish pond embankment according to the actual situation of the fish pond embankment to be laid;

[0025] (3) Carry out construction according to the parameters determined in steps (1) and (2).

[0029] According to the installation and layout method described above, the arrangement heights of the photovoltaic brackets of different rows of fish pond ridges are different and the arrangement heights of the photovoltaic brackets of each row of fish pond ridges are the same. The arrangement heights of the photovoltaic brackets of the fish pond ridges are successively increased or decreased along the direction perpendicular to the row arrangement, so as to avoid shadows between the front and rear rows of brackets during power generation;

[0030] The pipe piles are PHC prestressed high-strength concrete pipe piles. Since the construction site is a fish pond bank, the relative groundwater level is shallow, and bored pile construction is difficult, the construction of PHC prestressed high-strength concrete pipe piles is relatively convenient.

[0031] The above technical solution is only a feasible technical solution of the present invention, and the protection scope of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.

A limit angle steel 6 connecting the vertical column I 2 and the vertical column II 3 and arranged horizontally is also provided between the vertical column I 2 and the vertical column II 3.

[0053] Specifically, the photovoltaic bracket for the fish pond bank adopts a fixed bracket, which adopts an intermediate column bracket structure, is made of cold-bent thin-walled steel, and is hot-dip galvanized for corrosion protection.

In order to ensure that the front and rear components are not blocked during the period from 9 to 15 o'clock (true solar time) throughout the year, the layout height difference of the photovoltaic brackets on the embankment of the fish ponds in adjacent columns is 1.15m and the layout height of the photovoltaic brackets on the embankment of each column is the same. The layout height of the photovoltaic brackets on the embankment of the fish ponds increases or decreases in turn along the direction perpendicular to the column layout. The bracket structure adopts four types: 32×4 horizontal rows, 24×4 horizontal rows, 16×4 horizontal rows, and 8×4 horizontal rows. The photovoltaic brackets are arranged accordingly according to the length of the embankment, which improves the utilization rate of the land;

[0057] (3) According to the parameters determined in steps (1) and (2), construction is carried out first, PHC prestressed high-strength concrete pipe piles are constructed (because the groundwater level in the site is shallow and bored pile construction is difficult, PHC prestressed high-strength concrete pipe piles are selected), and then the photovoltaic support for the fish pond bank is installed on the pipe piles, and finally the photovoltaic module is installed on the photovoltaic support for the fish pond bank.
