Description

Technical Field

[0001] The invention relates to the field of photovoltaic equipment installation, and in particular to a cable-truss type flexible photovoltaic bracket. Background Art

[0002] A cable-truss flexible photovoltaic support is a structural system used to support solar photovoltaic panels. In areas with large terrain undulations, the cable-truss flexible photovoltaic support can better adapt to ground changes. Compared with traditional rigid supports, the cable-truss flexible support is usually easier to install, reducing the time and cost of on-site construction. However, existing cable-truss flexible photovoltaic supports usually include key parts such as load-bearing cables, component cables, cable truss struts, piles, side anchor systems, steel beams, cable truss struts, etc. The overall stiffness of the structure is improved by tensioning prestressed steel strands. However, it is difficult to make secondary adjustments to the tensioning of the steel strands after the setting is completed, which makes it difficult for the device to flexibly face complex and changeable airflow and environmental conditions.

[0003] Therefore, a cable-truss type flexible photovoltaic support is now developed to address the above problems. Summary of the invention

[0004] In order to overcome the disadvantage that the existing device improves the overall rigidity of the structure by tensioning the prestressed steel strands, and it is difficult to make secondary adjustments to the tensioned steel strands after setting, which makes it difficult for the device to flexibly cope with complex and changeable airflow and environmental conditions, the present invention provides a cable-truss type flexible photovoltaic support.

[0007] There are two mounting base columns;

[0008] A truss installed between the mounting base columns;

[0009] Fixed columns are installed on the truss, and there are two groups of them, which are symmetrically distributed front and back;

[0010] A cable installation mechanism, arranged between the installation base column and the truss, for adapting and adjusting the stable state of the installation;

[0011] The photovoltaic installation mechanism is arranged on the cable installation mechanism and is used for coordinated installation of the photovoltaic bracket.

[0012] More preferably, the cable installation mechanism comprises:

[0013] Guide seats, there are two guide seats, each of which is installed directly above the corresponding mounting base column;

[0014] A rope is slidably mounted between the guide seats and slidably connected to the fixed column;

[0015] A pulley block is installed on the outside of the corresponding mounting base column, and the ropes are all wound around the corresponding pulley block;

[0016] A sliding rod, slidably connected to the corresponding mounting base column and connected to the corresponding rope end;

[0017] The first spring is sleeved on the corresponding sliding rod and connected between the sliding rod and the mounting base.

[0018] More preferably, the photovoltaic installation mechanism comprises:

[0019] There are two mounting frames, which are slidably mounted between the ropes;

[0020] An installation component is arranged inside the installation frame, and two installation components cooperate with each other to quickly install the photovoltaic bracket;

[0021] A clamping frame, slidably mounted on the corresponding mounting frame, and used to cooperate with the mounting frame to compress and limit the rope;

[0022] The bidirectional screw rod is rotatably arranged on the outer side of the corresponding mounting frame and is threadedly connected to the adjacent clamping frame.

[0023] More preferably, an adjustment mechanism is also included, the adjustment mechanism includes a fixing rod, two fixing rods symmetrically connected to the inner side of the lower part of the mounting frame, a sleeve rod is slidably connected between the left and right adjacent fixing rods, a second spring is connected between the left and right adjacent fixing rods, the second spring is located inside the corresponding sleeve rod, a tightening wheel is rotatably connected to the right side of the lower part of the right mounting frame, a pull rope is connected between the mounting frames, the pull rope is wound around the tightening wheel, and a tightening assembly is installed on the right mounting frame.

[0024] More preferably, a tightening mechanism is also included, which includes a fixing plate, the fixing plate is connected to the truss, the fixing plate is slidably connected to an inclined frame, the front and rear ends of the inclined frame are rotatably connected to rotating wheels for pushing the rope, the lower part of the mounting frame is connected to a connecting frame, and the inner side of the connecting frame is rotatably connected to a rotating cylinder for pushing the inclined frame.

[0025] More preferably, an anti-shake plate is further included, and the anti-shake plate is connected between the upper parts of the mounting frames, and the anti-shake plate is used to maintain the stability of the upper part of the mounting frame to prevent the mounting frame from shaking violently when it is in the air.

[0026] More preferably, a pressure mechanism is further included, the pressure mechanism includes a fixing ring, four fixing rings are connected to the rope in a bilaterally symmetrical manner, and a third spring is connected between the fixing ring and the adjacent guide seat.

[0028] By adopting the above technical solution, the beneficial effects of the present invention are:

[0029] 1. When installing the rope, the present invention relies on the pulley group to adjust the corresponding tightness of the rope. During the adjustment process, the rope can maintain stability by relying on the tension applied by the pulley group. At the same time, when the rope is pulled, it will drive the corresponding sliding rod to slide, so that the corresponding first spring is compressed, thereby improving the stability of the rope.

[0030] 2. In order to adapt to photovoltaic brackets of different specifications and ensure the stability of the photovoltaic bracket after installation, during the installation of the photovoltaic bracket, the worm in the tightening assembly can be rotated according to the specifications of the photovoltaic bracket, so that the worm gear drives the tightening wheel to rotate. As the tightening wheel rotates, the pull rope will be pulled, thereby bringing the two mounting frames closer to each other. By adjusting the distance between the mounting frames, the distance between the mounting assemblies can be adjusted, thereby achieving the effect of adapting to photovoltaic brackets of different specifications.

[0031] 3. As the spacing between the mounting frames is controlled and adjusted, the connecting frame will move with the mounting frame, so that the rotating cylinder will push the inclined frame. After being pushed, the inclined frame will slide upward due to the extrusion force, thereby causing the rotating wheel to move upward. At this time, the rotating wheel will contact and push the rope, causing the rope to be pulled, and then the rope will enter a straightened state, so that the adjusted mounting frame can also maintain stability.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1

[0043] A cable-truss type flexible photovoltaic support, such as Figure 1 As shown, it includes mounting base columns 1, there are two mounting base columns 1, trusses 2 are installed between the mounting base columns 1, and fixed columns 3 are installed on the trusses 2. There are two groups of them, which are symmetrically distributed front to back. A cable mounting mechanism 4 is arranged between the mounting base columns 1 and the trusses 2 for adapting and adjusting the stable state of the installation. A photovoltaic mounting mechanism 5 is arranged on the cable mounting mechanism 4 for coordinating the installation of the photovoltaic bracket.

[0044] It should be noted that when installing the photovoltaic bracket, first rely on the cable installation mechanism 4 to fix and tighten the installation cable, and then rely on the photovoltaic installation mechanism 5 to install the photovoltaic bracket. After the installation is completed, rely on the cable installation mechanism 4 to adjust the tightness of the cable, so that the photovoltaic bracket can be stably installed.

[0045] like Figure 1 and Figure 2As shown, the cable installation mechanism 4 includes a guide seat 41, there are two guide seats 41, which are respectively installed directly above the corresponding installation base column 1, the rope 42 is slidably installed between the guide seats 41 and is slidably connected to the fixed column 3, the pulley group 43 is installed on the outer side of the corresponding installation base column 1, the rope 42 is wound on the corresponding pulley group 43, the sliding rod 45 is slidably connected to the corresponding installation base column 1, and is connected to the corresponding end of the rope 42, and the first spring 44 is sleeved on the corresponding sliding rod 45 and connected between the sliding rod 45 and the installation base.

[0046] It should be noted that when the rope 42 is installed, the pulley group 43 is used to adjust the corresponding tightness of the rope 42. During the adjustment process, the tension applied by the pulley group 43 enables the rope 42 to maintain stability. At the same time, when the rope 42 is pulled, the corresponding sliding rod 45 will slide, so that the corresponding first spring 44 is compressed, thereby improving the stability of the rope 42.

[0047] like Figure 1-Figure 3 As shown, the photovoltaic mounting mechanism 5 includes two mounting frames 51, which are slidably mounted between the ropes 42. The mounting components 52 are arranged on the inner side of the mounting frames 51, and the two mounting components 52 cooperate with each other to quickly install the photovoltaic bracket. The clamping frame 53 is slidably mounted on the corresponding mounting frame 51, and is used to cooperate with the mounting frame 51 to tighten and limit the rope 42. The bidirectional screw rod 54 is rotatably arranged on the outer side of the corresponding mounting frame 51 and is threadedly connected to the adjacent clamping frame 53.

[0048] It should be noted that, first, the mounting frame 51 is slid along the rope 42 to the specified position, and then the photovoltaic bracket is fixed and installed with the help of the mounting assembly 52. ​​After the installation is completed, the bidirectional screw rod 54 is rotated to adjust the position of the bracket 53, so that the bracket 53 slides outward respectively, thereby cooperating with the mounting frame 51 to clamp and fix the rope 42, ensuring the fit between the mounting frame 51 and the rope 42, and improving the stability of the photovoltaic bracket installation.

[0049] Example 2

[0050] On the basis of Example 1, Figure 1 and Figure 4As shown, it also includes an adjusting mechanism 6, which includes a fixing rod 61. Two front-to-rear symmetrical fixing rods 61 are connected to the inner side of the lower part of the mounting frame 51. A sleeve rod 62 is slidably connected between the left and right adjacent fixing rods 61. A second spring 63 is connected between the left and right adjacent fixing rods 61. The second spring 63 is located inside the corresponding sleeve rod 62. A tightening wheel 65 is rotatably connected to the right side of the lower right side of the mounting frame 51 on the right side, a pull rope 64 is connected between the mounting frames 51, and the pull rope 64 is wound around the tightening wheel 65. A tightening assembly 66 is installed on the right side mounting frame 51, and the tightening assembly 66 includes a worm wheel and a worm. The worm wheel is connected to the tightening wheel 65, and the worm is rotatably connected to the mounting frame 51, and the worm wheel and the worm are meshed with each other.

[0051] It should be noted that in order to adapt to photovoltaic brackets of different specifications and ensure the stability of the photovoltaic bracket after installation, during the installation of the photovoltaic bracket, the worm gear in the tightening assembly 66 can be rotated according to the specifications of the photovoltaic bracket, so that the worm gear drives the tightening wheel 65 to rotate. As the tightening wheel 65 rotates, the pull rope 64 will be pulled, thereby making the two mounting frames 51 closer to each other. By adjusting the distance between the mounting frames 51, the distance between the mounting assemblies 52 can be adjusted, thereby achieving the effect of adapting to photovoltaic brackets of different specifications.

[0052] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a tightening mechanism 7, which includes a fixed plate 71, the fixed plate 71 is connected to the truss 2, and the fixed plate 71 is slidably connected to an inclined frame 72. The front and rear ends of the inclined frame 72 are rotatably connected to rotating wheels 73 for pushing the rope 42. The lower part of the mounting frame 51 is connected to a connecting frame 74, and the inner side of the connecting frame 74 is rotatably connected to a rotating cylinder 75 for pushing the inclined frame 72.

[0053] It should be noted that as the spacing between the mounting frames 51 is controlled and adjusted, the connecting frame 74 will move with the mounting frame 51, so that the rotating cylinder 75 pushes the inclined frame 72. After being pushed, the inclined frame 72 will slide upward due to the extrusion force, thereby causing the rotating wheel 73 to move upward. At this time, the rotating wheel 73 will contact and push the rope 42, causing the rope 42 to be pulled, thereby causing the rope 42 to enter a straightened state, so that the adjusted mounting frame 51 can also maintain stability.

[0054] like Figure 1 and Figure 7 As shown, an anti-shake plate 8 is also included. The upper part of the mounting frame 51 is connected with the anti-shake plate 8. The anti-shake plate 8 is used to maintain the stability of the upper part of the mounting frame 51 to prevent the mounting frame 51 from shaking violently when it is in a high altitude.

[0055] like Figure 1 and Figure 8 As shown, a pressure mechanism 9 is also included, and the pressure mechanism 9 includes a fixing ring 92 . Four fixing rings 92 are connected to the rope 42 in a left-right symmetrical manner. A third spring 91 is connected between the fixing ring 92 and the adjacent guide seat 41 .

[0056] It should be noted that, during the use of the rope 42, the fixing ring 92 and the third spring 91 cooperate to further increase the bearing pressure of the rope 42, thereby making the rope 42 more stable.

[0057] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
