Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket based on a large-span carbon fiber cable truss structure. Background Art

[0002] Traditional fixed photovoltaics are densely installed on the ground through brackets. Although they can convert solar energy into electricity, they also make the comprehensive utilization rate of land low and prevent the land from playing a greater role. With the continuous development of science and technology, fixed photovoltaics have also ushered in technological innovation, moving photovoltaics from the ground to high altitudes. Therefore, large-span flexible photovoltaic brackets have emerged, forming a high-clearance photovoltaic array, which can convert solar energy into electricity and improve the comprehensive utilization rate of land.

[0003] The existing large-span flexible photovoltaic brackets mainly have the following technical defects: the existing large-span flexible photovoltaic bracket truss structure mainly adopts metal trusses and steel cables as building materials. The weight of metal trusses and steel cables is heavy, which has a certain impact on the load-bearing and stability of the large-span structure. At the same time, the metal material is exposed to the outdoor environment for a long time and is prone to corrosion, which affects the service life of the bracket. Moreover, the cables in the flexible photovoltaic bracket need to be pulled to a certain prestressed state by external equipment when building the photovoltaic bracket. However, in the subsequent use of the photovoltaic bracket, due to the pulling at one end of a rope, the prestressed state of a single tetrahedron is easily inconsistent. When facing different degrees of wind force outdoors, the photovoltaic and the cables are prone to shaking, and cannot be automatically adjusted individually according to the prestressed state of the single tetrahedron, which leads to the problem of poor stability of the large-span flexible photovoltaic bracket. Summary of the invention

[0006] The flexible stable structure includes a tetrahedron, a connecting rod, a connecting head and a support plate. The back of the photovoltaic panel is fixedly connected to a tetrahedron, the lower side of the tetrahedron is fixedly connected to a connecting head, a connecting rod is fixedly connected between adjacent photovoltaic panels and the connecting heads, and the lower side of the connecting head is fixedly connected to a support plate.

[0007] Furthermore, the adjustment mechanism includes a motor, a guide cylinder, a guide rod, an adjustment cylinder, a threaded rod and a fixing ring, the motor is fixedly connected to the lower side of the support plate, the output end of the motor is fixedly connected to the threaded rod, the outer side of the threaded rod is threadedly connected to the adjustment cylinder, the outer side of the adjustment cylinder is fixedly connected to the fixing ring, the lower side of the support plate is also fixedly connected to the guide cylinder, the upper side of the fixing ring is fixedly connected to the guide rod, and the guide rod slides on the inner side of the guide cylinder.

[0008] Furthermore, the detection mechanism includes a rope threading block and a mounting block, the rope threading block is fixedly connected to the lower side of the adjustment cylinder, the inner side of the rope threading block is fixedly connected to the mounting block by screws, and the mounting directions of the mounting blocks on the inner sides of adjacent rope threading blocks are opposite.

[0009] Furthermore, the detection assembly includes a hollow rubber block, a sliding rheostat, a toggle block, a fixed plate, a moving rod, a spring, a cylindrical tube and a connecting pipe, the hollow rubber block is fixedly installed on the inner side of the mounting block, the sliding rheostat is fixedly connected to the inner side of the mounting block and on the upper side of the hollow rubber block, the toggle block is slidably connected to the upper side of the sliding rheostat, the fixed plate is fixedly connected to the upper side of the toggle block, the moving rod is fixedly connected to one side of the fixed plate, the upper side of the hollow rubber block is connected to a connecting pipe, the other end of the connecting pipe is connected to the cylindrical tube, the moving rod slides on the inside of the cylindrical tube, the outer side of the moving rod is sleeved with a spring, one side of the spring is fixedly connected to the inner wall of the cylindrical tube, and the other side is fixedly connected to the moving rod.

[0010] Furthermore, the outer side of the A-shaped truss is fixedly connected with a plurality of cable fixing mechanisms, the main cable passes through the cable fixing mechanism, the structure of the cable fixing mechanism includes a fixing block, a cable fixing head and a through-hole screw, the outer side of the A-shaped truss is fixedly connected with a plurality of fixing blocks, the inner side of the fixing block is threadedly connected with a through-hole screw, one end of the through-hole screw is threadedly connected with a cable fixing head, and a through hole is provided on the inner side of the through-hole screw for the main cable to pass through the through hole.

[0011] Furthermore, the structure of the supporting mechanism includes a supporting rod and a supporting cable block. A supporting cable block is arranged on the outer side of the middle part of the main cable. The supporting cable block is composed of an upper cover plate and a lower base. The upper cover plate and the lower base are fixed by screws, and the lower side of the lower base is fixedly connected to the supporting rod.

[0012] Furthermore, the sliding rheostat is electrically connected to the motor, and the inner side of the hollow rubber block, the connecting pipe and the cylindrical tube is filled with hydraulic oil.

[0013] The motor drives the guide cylinder to rotate. While the guide cylinder rotates, under the guidance of the guide rod, it drives the fixed ring and the adjusting cylinder to move downward, and then synchronously drives the detection mechanism to move downward, so that the transverse auxiliary cable and the longitudinal auxiliary cable passing through the detection mechanism here are gradually tightened. In the process of gradual tightening, the transverse auxiliary cable and the longitudinal auxiliary cable squeeze the hollow rubber block accordingly. Since the interior of the hollow rubber block, the connecting pipe and the cylindrical tube are filled with hydraulic oil, the hydraulic oil in the hollow rubber block is squeezed, and then the moving rod is pushed, so that the moving rod compresses the spring, and then the moving rod drives the toggle block to slide on the sliding rheostat through the fixed plate, thereby changing the internal of the sliding rheostat. Resistance value, the greater the tightening degree of the transverse auxiliary cable and the longitudinal auxiliary cable, the greater the internal resistance value, until the resistance is infinite. Since the sliding rheostat is electrically connected to the motor, the motor stops working after tightening the transverse auxiliary cable and the longitudinal auxiliary cable to the set maximum degree, thereby realizing the single-point automatic adjustment of the prestressed state of the bracket. At the same time, due to the influence of external factors in the later stage, the transverse auxiliary cable and the longitudinal auxiliary cable are loose, which can also be automatically adjusted to the tightened state, so that the bracket has higher stability in the face of strong winds. At the same time, the transverse auxiliary cable and the longitudinal auxiliary cable are distributed in a wavy shape, which greatly improves the stability compared with the traditional planar distribution.

[0014] Furthermore, the A-shaped truss, X-shaped cables, main cables, transverse auxiliary cables and longitudinal auxiliary cables are all made of carbon fiber materials.

[0015] Furthermore, the inner side of the rope threading block is provided with transverse and longitudinal through holes corresponding to the transverse auxiliary cables and the longitudinal auxiliary cables, and the hollow rubber block is arranged in a semicircular shape, corresponding to the transverse auxiliary cables and the longitudinal auxiliary cables, and the transverse auxiliary cables and the longitudinal auxiliary cables pass through the circular hole formed by the combination of the rope threading block and the hollow rubber block.

[0016] Compared with the prior art, the present invention provides a photovoltaic support based on a large-span carbon fiber cable truss structure, which has the following beneficial effects:

[0017] 1. The photovoltaic bracket based on the large-span carbon fiber cable truss structure is made of carbon fiber materials through the A-shaped truss, X-shaped cable, main cable, transverse auxiliary cable and longitudinal auxiliary cable. The main structure of the large-span flexible photovoltaic bracket is built with lightweight materials. At the same time, the carbon fiber material has the advantages of good stability and durability, thereby achieving the purpose of the large-span flexible photovoltaic bracket with good stability and durability. At the same time, it has strong corrosion resistance, which solves the problem of using metal trusses and steel cables as building materials, the heavy weight of metal trusses and steel cables, which has a certain impact on the load-bearing and stability of the large-span structure, and the metal material is exposed to the outdoor environment for a long time, which is prone to corrosion and affects the service life of the bracket.

[0018] 2. The photovoltaic bracket based on the large-span carbon fiber cable truss structure realizes the single-point automatic adjustment of the prestressed state of the bracket through the cooperation between the flexible stable structure, the adjustment mechanism, the detection mechanism, the detection component, the transverse auxiliary cable and the longitudinal auxiliary cable. At the same time, due to the influence of external factors in the later stage, the transverse auxiliary cable and the longitudinal auxiliary cable are loose, and they can also be automatically adjusted to a taut state, so that the bracket has higher stability in the face of strong winds. At the same time, the transverse auxiliary cable and the longitudinal auxiliary cable are distributed in a wavy shape. Compared with the traditional planar distribution, the stability is greatly improved, which solves the problem that the prestressed state of a single tetrahedron is inconsistent when pulling at one end of a rope. When facing different degrees of wind force outdoors, the photovoltaic and the cable are prone to shaking, and it is impossible to perform automatic single adjustment according to the prestressed state of a single tetrahedron, which leads to the problem of poor stability of the large-span flexible photovoltaic bracket.

[0019] 3. The photovoltaic bracket based on the large-span carbon fiber cable truss structure adopts a slider design for the mounting block, so that when it is installed with the rope threading block, the mounting block can be easily pushed into the rope threading block, and then fixed with two screws. When the electronic components inside the mounting block are damaged, they can be replaced modularly, which greatly improves the installation efficiency, as well as the subsequent maintenance efficiency and maintenance cost.

The structure of the cable fixing mechanism 11 includes a fixing block 111, a cable fixing head 112 and a through-hole screw 113.

[0042] Furthermore, the sliding rheostat 102 is electrically connected to the motor 81 , and the inner sides of the hollow rubber block 101 , the connecting tube 108 and the cylindrical tube 107 are filled with hydraulic oil.

[0043] The motor 81 drives the guide cylinder 82 to rotate. While the guide cylinder 82 is rotating, under the guidance of the guide rod 83, it drives the fixing ring 86 and the adjusting cylinder 84 to move downward, and then synchronously drives the detection mechanism 9 to move downward, so that the transverse auxiliary cable 13 and the longitudinal auxiliary cable 14 passing through the detection mechanism 9 here are gradually tightened. In the process of gradual tightening, the transverse auxiliary cable 13 and the longitudinal auxiliary cable 14 squeeze the hollow rubber block 101 accordingly. Since the interior of the hollow rubber block 101, the connecting pipe 108, and the cylindrical tube 107 are filled with hydraulic oil, the hydraulic oil in the hollow rubber block 101 is squeezed, and then the moving rod 105 is pushed, so that the moving rod 105 compresses the spring 106, and then the moving rod 105 drives the toggle block 103 on the sliding rheostat 102 through the fixed plate 104. Sliding, thereby changing the internal resistance of the sliding rheostat 102, so that the greater the degree of tension of the transverse auxiliary cable 13 and the longitudinal auxiliary cable 14, the greater the internal resistance, until the resistance is infinite. Since the sliding rheostat 102 is electrically connected to the motor 81, after the motor 81 tightens the transverse auxiliary cable 13 and the longitudinal auxiliary cable 14 to the set maximum degree, the motor 81 stops working, thereby realizing the single-point automatic adjustment of the prestressed state of the bracket.

The transverse auxiliary cables 13 and the longitudinal auxiliary cables 14 pass through the circular hole formed by the combination of the rope threading block 91 and the hollow rubber block 101.

[0046] The specific usage and function of this embodiment.

[0047] When in use, the photovoltaic bracket is first built up, and one end of the main cable 3 on both sides of the A-shaped truss 1 can be fixed to the ground by anchor nails. At the same time, the main cable 3 can also be passed through the cable fixing mechanism 11, and an external limiting ring can be installed at the port of the main cable 3. The limiting ring has a larger aperture than the through hole on the inner side of the through hole screw 113, thereby achieving the effect of limiting the main cable 3. The two methods of fixing the main cable 3 can be selected according to the usage scenario.

[0048] After the A-shaped truss 1, X-shaped cable 2, main cable 3 and support rod 121 are built, the photovoltaic panel 4 is slid on the main cable 3 and then slidably installed. After the photovoltaic panel 4 is slid to the corresponding position, the back side is fixed to the main cable 3 by the lock 6. After the entire photovoltaic panel 4 is installed, the corresponding tetrahedron 71 is installed on the back side of the photovoltaic panel 4, and the adjacent tetrahedrons 71 are fixedly connected by connecting rods 72. Then the adjustment mechanism 8 and the detection mechanism 9 are correspondingly installed on the lower side of the support plate 74, and then the transverse auxiliary cables 13 and the longitudinal auxiliary cables 14 are distributed correspondingly through the through holes on the inner side of the detection mechanism 9, and then the ports on both sides of the transverse auxiliary cables 13 and the longitudinal auxiliary cables 14 are fixed by external fixing devices. At this point, the photovoltaic bracket with a large-span carbon fiber cable truss structure is completed.

[0049] After the construction is completed, the circuit between the detection component 10 and the corresponding motor 81 is connected. At this time, the motor 81 is started, and the motor 81 drives the guide cylinder 82 to rotate. While the guide cylinder 82 rotates, under the guidance of the guide rod 83, it drives the fixing ring 86 and the adjusting cylinder 84 to move downward, and then synchronously drives the detection mechanism 9 to move downward, so that the transverse auxiliary cable 13 and the longitudinal auxiliary cable 14 passing through the detection mechanism 9 here are gradually tightened. In the process of gradual tightening, the transverse auxiliary cable 13 and the longitudinal auxiliary cable 14 squeeze the hollow rubber block 101 accordingly. Since the interior of the hollow rubber block 101, the connecting pipe 108, and the cylindrical tube 107 are filled with hydraulic oil, the hydraulic oil in the hollow rubber block 101 is squeezed, thereby pushing the movement rod 105, so that the movement rod 105 compresses the spring 106, and then the movement rod 105 passes through the fixed plate 1 04 drives the toggle block 103 to slide on the sliding rheostat 102, thereby changing the internal resistance of the sliding rheostat 102, so that the greater the degree of tension of the transverse auxiliary cable 13 and the longitudinal auxiliary cable 14, the greater the internal resistance, until the resistance is infinite. Since the sliding rheostat 102 is electrically connected to the motor 81, after the motor 81 tightens the transverse auxiliary cable 13 and the longitudinal auxiliary cable 14 to the set maximum degree, the motor 81 stops working, thereby realizing the single-point automatic adjustment of the prestressed state of the bracket. At the same time, due to the influence of external factors in the later stage, the transverse auxiliary cable 13 and the longitudinal auxiliary cable 14 are loose, and they can also be automatically adjusted to the tightened state, so that the bracket also has higher stability when facing strong winds. At the same time, the transverse auxiliary cable 13 and the longitudinal auxiliary cable 14 are distributed in a wavy shape, which greatly improves the stability compared with the traditional planar distribution.
