Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power station support technology, and specifically relates to a flexible photovoltaic support device. Background Technology

[0002] As a crucial component of renewable energy, solar energy plays an increasingly vital role in promoting new energy development and transforming the power structure. With growing attention to environmental pollution and energy consumption, the photovoltaic (PV) power generation industry has received greater focus, leading to a proliferation of PV applications and diverse support structures. From centralized PV power plants to distributed PV systems, the application scope of PV power generation is expanding. Centralized PV power plants are typically built in regions with abundant solar resources, such as the Northwest, while distributed PV systems can be installed on the rooftops of industrial and commercial buildings, residential buildings, and other locations.

[0003] Distributed photovoltaic power stations typically have a small installed capacity and are built near users. They can achieve short-distance power transmission, reduce line losses, and improve energy efficiency. They can be flexibly configured according to the actual electricity demand of users and can also be easily connected to the existing power grid system to achieve complementary operation with the public power grid.

[0004] Traditional distributed photovoltaic (PV) power generation systems often use rigid structures for their PV brackets, which have multiple fixed brackets laid out flat inside. These fixed brackets require numerous support foundations and have small spacing. In places like rest stops, coalbed methane stations, and parking lots, space constraints due to ground obstacles prevent the installation of these fixed brackets. Therefore, we need to provide a PV bracket that can adapt to different environments within these sites. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer and more understandable, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] Distributed photovoltaic power stations typically have a small installed capacity and are built near users. They can achieve short-distance power transmission, reduce line losses, and improve energy efficiency. They can be flexibly configured according to the actual electricity demand of users and can also be easily connected to the existing power grid system to achieve complementary operation with the public power grid.

[0023] Traditional distributed photovoltaic (PV) power generation systems often use rigid structures for their PV brackets, which have multiple fixed brackets laid out flat inside. These fixed brackets require numerous support foundations and have small spacing. In places like rest stops, coalbed methane stations, and parking lots, space constraints due to ground obstacles prevent the installation of these fixed brackets. Therefore, we need to provide a PV bracket that can adapt to different environments within these sites.

[0024] like Figure 1 and Figure 3 As shown, in order to achieve the above objectives, this utility model provides a flexible photovoltaic support device 100, including a support structure 10, a laying structure 30 for mounting photovoltaic panels, and at least one anti-sway structure 50. The support structure 10 is provided with two support frames 11 that are directly opposite each other and spaced apart. The laying structure 30 includes a plurality of parallel and spaced main cables 31. The two ends of each main cable 31 are respectively connected to the top of the two support frames 11. An anti-sway structure 50 is detachably mounted on at least two adjacent main cables 31.

[0025] The flexible photovoltaic support device 100 of this utility model includes a support structure 10, a laying structure 30 for mounting photovoltaic panels, and at least one anti-sway structure 50. The support structure 10 has two opposing support frames 11. The laying structure 30 includes multiple parallel and spaced main cables 31. The two ends of each main cable 31 are respectively connected to the top of the two support frames 11. Each anti-sway structure 50 is detachably mounted on at least two adjacent main cables 31. The two opposing support frames 11 are located on both sides of the rest station. The laying structure 30 uses multiple main cables 31 to span the station roof and connects to the two support frames 11 at both ends. This makes reasonable use of spatial layout conditions to avoid obstacles in the station, while reducing the setting of internal foundation supports. This saves materials and effectively solves the problem of space constraints caused by the need for internal fixed supports in traditional support systems, effectively solving the power supply problem in the station.

[0026] It should be noted that the flexible photovoltaic support device 100 is very suitable for sites such as rest stops, coalbed methane stations, and parking lots where space is limited and fixed supports cannot be installed. The aforementioned flexible photovoltaic support device 100 is applicable to sites such as rest stops, coalbed methane stations, and parking lots, and can solve the current situation where some sites have difficulty in accessing electricity, and traditional fixed supports are not flexible enough, cannot be deployed, and are not economically ideal. It greatly improves the utilization rate of building land, while increasing power generation capacity, saving energy, and has high economic and social benefits and promotional value.

[0027] Combination Figure 1 and Figure 2 As shown, optionally, the two ends of the main cable 31 are fastened to the support frame 11 by anchors 60.

[0028] In this embodiment, the connection between the end of the main cable 31 and the support frame 11 is protected by a special anchor sleeve 70, such as... Figure 2 As shown, it enhances the stability of the main cable 31 connected to the support frame 11 and has a protective function at the end connection to prevent the connection from becoming loose.

[0029] Optionally, the span of the two opposing support frames 11 is 20m-50m.

[0030] In this embodiment, the span of the two opposing support frames 11 is 20m-50m, which makes the lateral span of the support structure 10 of the flexible photovoltaic bracket device 100 large. It is suitable for sites such as rest stations, coalbed methane stations, and parking lots, especially for crossing low-rise buildings. It increases the power generation capacity without affecting the utilization of the space below, saves energy, and can solve the current situation of power shortage in some stations, insufficient flexibility of traditional fixed brackets, inability to be arranged and unsatisfactory economics. It greatly improves the utilization rate of building land and has good comprehensive benefits. It lays a solid foundation for the research and development and large-scale complex application of more efficient and economical flexible photovoltaic bracket systems.

[0031] Reference Figure 1 As shown, optionally, each support frame 11 includes a pile foundation 111, multiple tripods 112 and a main crossbeam 113. The multiple tripods 112 are arranged side by side on the pile foundation 111, and the main crossbeam 113 is located on top of the multiple tripods 112. The right-angled sides of the two opposing tripods 112 on the two sides of the support frame 11 are parallel and the hypotenuses are far apart from each other.

[0032] In this embodiment, the pile foundation 111 is located on the ground. The pile foundation 111 can be set for the support frame 11 on one side, that is, the pile foundation 111 is set for the tripods 112 on both sides. The tripods 112 of the support frame 11 have right-angled sides and hypotenuses. The right-angled sides of the tripods 112 set on both sides of the station are parallel. The right-angled sides of the two opposite tripods 112 on both sides of the support frame 11 are parallel and the hypotenuses are set far apart from each other, so that the hypotenuses occupy part of the space outside the station. The setting of the hypotenuses can improve the verticality of the right-angled sides and improve the support stability of the main cable 31 spanning the top of the tripod 112.

[0033] Optionally, the tripod 112 includes a column 1121 and a diagonal brace 1122. The column 1121 and the diagonal brace 1122 are respectively installed on the pile foundation 111 at one end. The top of the diagonal brace 1122 is connected to the column 1121 to form a tripod 112 support with the column 1121. The diagonal braces 1122 of the two tripods 112 on opposite sides are arranged in a figure-eight shape. The main crossbeam 113 is installed on the top of the column 1121 and there is a gap between the top of the main crossbeam 113 and the top of the diagonal brace 1122.

[0034] In this embodiment, the pile foundation 111 can be installed as a single piece, or it can be installed separately for each corresponding column 1121 and diagonal brace 1122. The column 1121 is vertically installed on the pile foundation 111, and the diagonal brace 1122 is diagonally installed on the corresponding pile foundation 111 to support and pull the column 1121. The main crossbeam 113 is installed at the top of the column 1121, and there is a gap between the top of the main crossbeam 113 and the top of the diagonal brace 1122. The pile foundation 111 of the column 1121 and the pile foundation 111 of the tripod 112 are installed alternately, so that the diagonal brace 1122, the line connecting the two pile foundations 111, and the column 1121 form a triangular stable support. The diagonal braces 1122 of the two tripods 112 facing each other on both sides are arranged in a figure-eight shape, so that the diagonal braces 1122 do not occupy the space inside the site, and can resist the downward pressure of the photovoltaic panel on the laying structure 30 to a certain extent, thus improving the stability of the photovoltaic panel installation.

[0035] Optionally, the support frame 11 also includes at least one connecting beam 114, which is provided on a plurality of parallel columns 1121. The connecting beam 114 is spaced between the main beam 113 and the pile foundation 111. That is, the connecting beam 114 connects the plurality of columns 1121 arranged on one side laterally, thereby improving the constant spacing of the parallel columns 1121 and improving the stability of the vertical arrangement of the columns 1121, thus providing good support conditions for the installation of photovoltaic panels.

[0036] The aforementioned flexible photovoltaic support device 100 is constructed through a process including foundation construction (setting up piles 111), installation of steel columns 1121, installation of steel diagonal braces 1122, installation of steel crossbeams, installation of main cables 31, and installation of anti-sway structures 50, forming a stable flexible photovoltaic support structure. After construction, the flexible support structure can form a stable spatial whole for the photovoltaic module array, effectively resisting wind vibration and significantly reducing the occurrence of photovoltaic panel damage.

[0037] Reference Figure 1 , Figure 3 As shown, optionally, the anti-sway structure 50 includes at least one anti-sway group 51, the anti-sway group 51 includes a connecting frame 511 and at least two anti-sway frames 512, the top of each anti-sway frame 512 is connected to two adjacent main cables 31, and the bottom is detachably connected to the connecting frame 511, the connecting frame 511 is arranged parallel to the main cable 31.

[0038] In this embodiment, at least one anti-sway group 51 includes at least two anti-sway frames 512. The at least two anti-sway frames 512 are arranged at intervals along the extension direction of the main cable 31. Each anti-sway frame 512 can fix the parallel position of two adjacent main cables 31, improve the consistency of the parallel spacing between multiple main cables 31, and improve the installation stability of photovoltaic panels laid on the main cable 31.

[0039] At least two anti-sway frames 512 are detachably connected to the bottom of the connecting frame 511, and the connecting frame 511 is set parallel to the main cable 31, so that the anti-sway structure 50 has two fixed points on two adjacent main cables 31 through the two anti-sway frames 512. That is, at least two points on the extension path of a single main cable 31 are fixed to prevent swaying. At the same time, the two main cables 31 are set in parallel and adjacent to each other and fixed by the same anti-sway structure 50, forming a constraint between them and improving the feasibility of anti-swaying.

[0040] Optionally, the anti-sway bracket 512 is arranged in an inverted triangle shape from top to bottom, and the inverted triangle axes of at least two anti-sway brackets 512 of an anti-sway group 51 are located on the same straight line.

[0041] In this embodiment, the inverted triangle shape can lock two adjacent main cables 31 by the included angle of the triangle. At least two coaxial anti-sway frames 512 are connected at the bottom of the inverted tripod 112 by a connecting frame 511. The photovoltaic panel is set at the top of the inverted tripod 112. The bottom space is appropriately utilized to arrange the connecting frame 511 of the anti-sway group 51, thereby improving the layout flexibility and reliability of the anti-sway group 51.

[0042] Optionally, the anti-sway structure 50 includes a plurality of anti-sway groups 51 arranged in parallel, and the anti-sway frame 512 also includes a combination rod 52, and two adjacent connecting frames 511 are detachably connected by the combination rod 52.

[0043] In this embodiment, the parallel arrangement direction of the multiple anti-sway groups 51 is the same as the parallel arrangement direction of the multiple main cables 31. One anti-sway group 51 in one anti-sway structure 50 can fix two adjacent main cables 31 to prevent swaying. The multiple anti-sway groups 51 arranged in parallel can fix two adjacent main cables 31 in pairs to prevent swaying twice through the combination rod 52. This increases the number of main cables 31 that restrict each other between the same anti-sway structure 50, greatly improves the mutual spacing between multiple parallel main cables 31, and improves the laying stability of photovoltaic panels.

[0044] Optionally, at least two combined rods 52 are provided in an anti-sway structure 50, and the two ends of each combined rod 52 are connected to the same side ends of two parallel connecting frames 511.

[0045] In this embodiment, to enhance the connection strength between anti-sway groups 51, at least two combined rods 52 are provided between each pair of adjacent anti-sway groups 51. The two ends of each combined rod 52 are connected to the same side ends of two parallel connecting frames 511. Within the same anti-sway group 51, two, three, or more anti-sway frames 512 may be provided, and these frames are spaced apart along the extension direction of the main cable 31. Within the same anti-sway structure 50, two, three, or more anti-sway groups 51 may be provided. These anti-sway groups 51 are spaced apart along the parallel direction of the main cable 31 and connected by at least two combined rods 52. The at least two combined rods 52 are arranged parallel to each other and perpendicular to the main cable 31, improving the overall anti-sway reliability of the anti-sway structure 50.

[0046] Furthermore, one anti-sway structure 50 can be installed on the same main cable 31, or multiple anti-sway structures 50 can be staggered to provide anti-sway measures at multiple points on the main cable 31, thereby improving the stability of the main cable 31 during swaying. See the example for reference. Figure 1 and Figure 3 The anti-sway structure 50 is provided with two sets of anti-sway groups 51, and each anti-sway group 51 is provided with two anti-sway frames 512, so that the same anti-sway structure 50 can fix four adjacent main cables 31 to prevent swaying.

The centers of the tripods 112 in the same row of multiple spans must be kept in a straight line and connected with connecting rods. At the same time, connect two adjacent sets of single-span tripods 112 with combination rods 52 to form an overall stable structure.
