Description

Technical Field

[0001] This utility model relates to the field of photovoltaic flexible support technology, specifically a photovoltaic large-span flexible support based on fishery-solar complementary technology. Background Technology

[0002] The large-span flexible support technology for photovoltaics based on fishery-solar integration is an innovative model that combines aquaculture and photovoltaic power generation. By optimizing structural design and material application, it solves the shortcomings of traditional supports in complex terrain, wind resistance and space utilization.

[0003] In the prior art, patent application CN202420061636.6 discloses a flexible photovoltaic support system, which includes steel strands, a series of side piles connected by cables, several intermediate piles, several sets of support components, and combined anchors. Each of the intermediate piles, support components, and combined anchors has at least one component. A solar panel is mounted on the upper end of the steel strands via a fixing component. The intermediate piles are connected in series by steel strands to increase continuity. The support components are connected to form a mesh structure. The side piles are fixed on both sides by cables. One end of each steel strand and cable is connected to the top of a side column, and the other end of each cable is installed on the combined anchor. The steel strands pass through several steel strand fixing components and clamps, with the other end fixed to the top of another side column. This system has a reasonable structure, with the steel strands interwoven and connected to the support components, generating mutual support and making the photovoltaic system more tightly connected. This facilitates mutual assistance and force sharing in mountainous terrain.

[0004] However, in order to prevent the steel cables from sagging too much in the middle, the existing flexible photovoltaic support system requires a large number of columns to support the steel cables. Moreover, many of these columns are located in the water, which makes it easy for fishermen to collide with the columns in the water when they are working on their boats. This can damage the stability of the support system and the fishermen's boats. Utility Model Content

[0005] The purpose of this invention is to provide a large-span flexible photovoltaic support structure based on fishery-solar complementarity, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large-span flexible photovoltaic support based on fishery-solar complementarity, comprising: a column, a crossbeam fixed to the top of the column, a photovoltaic installation steel cable provided on the surface of the column, a clamp installed on the surface of the photovoltaic installation steel cable by bolts and nuts, a first mounting frame and a second mounting frame installed at the top of the clamp, a photovoltaic power generation panel fixed at the top of the first mounting frame and the second mounting frame, and a reinforcing steel cable fixed between the crossbeam and the photovoltaic installation steel cable.

[0007] Preferably, the reinforcing steel cables are provided in several groups, and the groups of reinforcing steel cables are linearly distributed.

[0008] Preferably, a hoisting steel cable is fixed to the middle bottom end of the photovoltaic installation steel cable, a counterweight is fixed to the bottom end of the hoisting steel cable, and an air cushion is fitted and fixed on the surface of the counterweight.

[0009] Preferably, the photovoltaic installation steel cables are provided in several sets, and two adjacent sets of photovoltaic installation steel cables are used together. A first mounting frame is fixed on the clamps provided on the surface of one set of photovoltaic installation steel cables, and a second mounting frame is fixed on the clamps provided on the surface of the other set of photovoltaic installation steel cables.

[0010] Preferably, both the first mounting bracket and the second mounting bracket have an "L"-shaped plate structure, and the length of the vertical plate of the first mounting bracket is less than the length of the vertical plate of the second mounting bracket.

[0011] Preferably, the surface of the column has a steel cable hole, and a movable pulley is rotatably connected in the steel cable hole, and the photovoltaic installation steel cable is slidably connected in the movable pulley.

[0012] Preferably, a first concrete pile foundation is installed at the bottom of the column via a flange and stud nuts. The first concrete pile foundation is fixed to the bank, and a second concrete pile foundation is also fixed to the bank. A crossbeam cable is fixed between the second concrete pile foundation and the crossbeam, and the two ends of the photovoltaic installation cable are fixed to the surface of the second concrete pile foundation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The large-span flexible photovoltaic support frame proposed in this utility model can increase the span between two adjacent sets of columns while ensuring that the photovoltaic installation steel cables do not sag excessively. At the same time, the diameter of the columns is increased to ensure that the strength of the columns is sufficient to bear the weight of the photovoltaic installation steel cables. This eliminates the need for columns erected in fish ponds and avoids collisions between fishermen's boats and columns when they are sailing on the fish ponds. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1: Please refer to Figures 1 to 2 This utility model provides a technical solution: a large-span flexible photovoltaic support structure based on solar-fishery integration, comprising: a column 1, a crossbeam 2 fixed to the top of the column 1, photovoltaic installation cables 3 arranged on the surface of the column 1, and clamps 4 installed on the surface of the photovoltaic installation cables 3 by bolts and nuts, a first mounting frame 5 and a second mounting frame 11 installed on the top of the clamps 4, photovoltaic panels 6 fixed to the top of the first mounting frame 5 and the second mounting frame 11, a reinforcing cable 10 fixed between the crossbeam 2 and the photovoltaic installation cables 3, the reinforcing cables 10 being arranged in several groups, the groups of reinforcing cables 10 being linearly distributed, and the photovoltaic installation cables 3 being arranged in several groups, with two adjacent groups of photovoltaic installation cables 3 used together, and the clamps 4 on the surface of one group of photovoltaic installation cables 3 being fixed. A first mounting frame 5 is fixed, and a second mounting frame 11 is fixed on the clamps 4 set on the surface of another set of photovoltaic mounting steel cables 3. Both the first mounting frame 5 and the second mounting frame 11 are "L"-shaped plate structures. The vertical plate length of the first mounting frame 5 is less than the vertical plate length of the second mounting frame 11. A steel cable hole 14 is opened on the surface of the column 1. A movable pulley 15 is rotatably connected in the steel cable hole 14. The photovoltaic mounting steel cable 3 is slidably connected in the movable pulley 15. The bottom end of the column 1 is installed with a first concrete pile foundation 12 through a flange and stud nuts. The first concrete pile foundation 12 is fixed to the bank. A second concrete pile foundation 13 is also fixed to the bank. A crossbeam steel cable 16 is fixed between the second concrete pile foundation 13 and the crossbeam 2. The two ends of the photovoltaic mounting steel cable 3 are fixed to the surface of the second concrete pile foundation 13.

[0020] In actual use, a first concrete pile foundation 12 and a second concrete pile foundation 13 are poured on the bank of the fishpond. A column 1 is installed on the surface of the first concrete pile foundation 12, and a crossbeam 2 is fixed to the top of the column 1. After the photovoltaic installation cable 3 passes through the cable hole 14 and overlaps on the pulley 15, the photovoltaic installation cable 3 is straightened and both ends are fixed to the second concrete pile foundation 13. Then, a clamp 4 with a first mounting frame 5 is installed on one set of photovoltaic installation cables 3, and a clamp 4 with a second mounting frame 11 is installed on the other set of photovoltaic installation cables 3. The horizontal and vertical plates of the first mounting frame 5 and the second mounting frame 11 are inclined so that the tops of the horizontal plates of the first mounting frame 5 and the second mounting frame 11 are on the same plane. Then, the photovoltaic panel 6 is installed on the first mounting frame 5 and the second mounting frame 11 using bolts and screws. On frame 11, several sets of reinforcing steel cables 10 are fixed between the crossbeam 2 and the photovoltaic installation steel cable 3, so that the weight of the photovoltaic installation steel cable 3 is transferred to the crossbeam 2 and then to the column 1. Through the tension of the several sets of reinforcing steel cables 10, excessive sag in the middle of the photovoltaic installation steel cable 3 can be prevented. At the same time, crossbeam steel cables 16 are fixed at both ends of the crossbeam 2, and the crossbeam steel cables 16 are straightened and fixed to the second concrete pile foundation 13, so that the two ends of the column 1 have equal tension, preventing the column 1 from tilting. Through the above settings, while ensuring that the photovoltaic installation steel cable 3 is prevented from sag excessively, the span between two adjacent sets of columns 1 can be increased, and the diameter of the column 1 can be increased to ensure that the strength of the column 1 is sufficient to bear the weight of the photovoltaic installation steel cable 3. Thus, the column 1 set up in the fishpond can be eliminated, avoiding collisions between fishermen's boats and the column 1 when sailing on the fishpond.

[0021] Example 2: Based on Example 1, in order to prevent the photovoltaic installation cable 3 from bending upward when the wind blows the photovoltaic panel 6 upward with great force, a hoisting cable 7 is fixed to the middle bottom end of the photovoltaic installation cable 3, a counterweight 8 is fixed to the bottom end of the hoisting cable 7, and an air cushion 9 is fixed on the surface of the counterweight 8.

[0022] A hoisting steel cable 7 is fixed at the bottom middle of the photovoltaic installation steel cable 3, and a counterweight 8 is fixed at the bottom of the hoisting steel cable 7. An air cushion 9 is fitted on the surface of the counterweight 8. Under normal conditions, the counterweight 8 floats on the water surface through the air cushion 9 and will not put too much load on the photovoltaic installation steel cable 3. When the wind blows the photovoltaic panel 6 upward with great force, causing the photovoltaic installation steel cable 3 to tend to bend upward, the counterweight 8 pulls the photovoltaic installation steel cable 3 downward through the hoisting steel cable 7, which can prevent the photovoltaic installation steel cable 3 from bending upward. At the same time, the counterweight 8 floats on the water surface. When a boat accidentally collides with the counterweight 8, the counterweight 8 can move laterally within a certain range without causing too much damage to the boat.

[0023] In actual use, a first concrete pile foundation 12 and a second concrete pile foundation 13 are poured on the bank of the fishpond. A column 1 is installed on the surface of the first concrete pile foundation 12, and a crossbeam 2 is fixed to the top of the column 1. After the photovoltaic installation cable 3 passes through the cable hole 14 and overlaps on the pulley 15, the photovoltaic installation cable 3 is straightened and both ends are fixed to the second concrete pile foundation 13. Then, the clamp 4 with the first mounting frame 5 is installed on one set of photovoltaic installation cables 3, and the clamp 4 with the second mounting frame 11 is installed on the other set of photovoltaic installation cables 3. The first mounting frame 5... The horizontal and vertical plates of the first and second mounting brackets 11 are inclined together, so that the tops of the horizontal plates of the first and second mounting brackets 11 are on the same plane. The photovoltaic panels 6 are then installed on the first and second mounting brackets 5 and 11 using bolts and screws. Several sets of reinforcing steel cables 10 are fixed between the crossbeam 2 and the photovoltaic mounting cables 3, so that the weight of the photovoltaic mounting cables 3 is transferred to the crossbeam 2 and then to the column 1. The tension of the reinforcing steel cables 10 prevents excessive sagging in the middle of the photovoltaic mounting cables 3. Simultaneously, crossbeam cables 16 are fixed at both ends of the crossbeam 2. The crossbeam steel cable 16 is straightened and fixed to the second concrete pile foundation 13, thereby ensuring equal tension at both ends of the column 1 and preventing the column 1 from tilting. This arrangement ensures that the photovoltaic installation steel cable 3 does not sag excessively while increasing the span between adjacent sets of columns 1. Simultaneously, increasing the diameter of the column 1 ensures its strength is sufficient to bear the weight of the photovoltaic installation steel cable 3, thus eliminating the need for the column 1 erected in the fishpond and preventing collisions between fishermen's boats and the column 1. A hoisting steel cable 7 is fixed at the bottom middle of the photovoltaic installation steel cable 3, and the bottom end of the hoisting steel cable 7 is fixed... The counterweight 8 has an air cushion 9 on its surface. Under normal conditions, the counterweight 8 floats on the water surface through the air cushion 9, which will not put too much load on the photovoltaic installation cable 3. When the wind blows the photovoltaic panel 6 upward with great force, causing the photovoltaic installation cable 3 to tend to bend upward, the counterweight 8 pulls the photovoltaic installation cable 3 downward through the hoisting cable 7, which can prevent the photovoltaic installation cable 3 from bending upward. At the same time, the counterweight 8 floats on the water surface. When a ship accidentally collides with the counterweight 8, the counterweight 8 can move laterally within a certain range without causing too much damage to the ship.
