Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic flexible brackets, and specifically relates to a wind-resistant adjusting device for a photovoltaic flexible bracket. Background Technique

[0002] A photovoltaic flexible bracket is a large-span photovoltaic module support structure formed by a prestressed flexible cable structure, which has the characteristics of high clearance and large span. It is fixed at both ends, and the span of the cable structure is usually between 20 meters and 40 meters, and can reach up to 100 meters at most. At the same time, the module can be 2 meters to 30 meters above the ground. The design of this bracket system aims to improve the comprehensive utilization efficiency of land. Compared with the fixed bracket in the traditional mode, the panel installation capacity of the flexible bracket can be increased by nearly three times, and it has the layout advantages of high clearance below the module and few pile foundations;

[0003] The wind-resistant adjusting device of the photovoltaic flexible bracket is a design that can facilitate installation and connection, and at the same time always keep the steel cable in a straightened state, aiming to improve the reinforcement stability;

[0004] Although the conventional photovoltaic flexible bracket has structures such as steel cables to ensure the stability of the structure, considering that the structure of the photovoltaic bracket itself has a certain degree of flexibility in adjustment, the adjustment of the steel cable structure is relatively inconvenient, resulting in a certain degree of sacrifice of the structural flexibility of the photovoltaic bracket itself. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wind-resistant adjusting device for a photovoltaic flexible bracket to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A wind-resistant adjusting device for a photovoltaic flexible bracket, including a bearing bracket and a traction assembly. The lifting columns are vertically and symmetrically installed at the left and right of the bottom of the bearing bracket, and the mounting frame is horizontally connected and installed at the bottom of the lifting columns. The traction assembly is fixedly installed at the top of the left and right ends of the mounting frame, and the base assemblies are connected to the bottom of the left and right ends of the mounting frame. The traction assembly includes a winding frame, a servo motor, a metal cable and a traction ring. The servo motor is horizontally installed on one side of the winding frame, the metal cable is wound on the middle surface of the winding frame, and the traction ring is fixed at the end of the metal cable away from the winding frame.

[0007] Preferably, the bearing bracket includes a connecting frame, a support frame, a rotating pile and a connecting ring. The connecting frame is connected to the bottom of the support frame, the rotating piles are installed at both the left and right ends of the bottom of the support frame, and the connecting ring is hung at the bottom of the rotating pile.

[0008] Preferably, the connecting frame and the support frame are welded together, and the connecting ring is sleeved inside the bottom end of the rotating pile.

[0009] Preferably, the lifting column includes a hydraulic column, a connecting shaft frame, an assembly pile and fastening bolts. A connecting shaft frame is installed at the top end of the hydraulic column, an assembly pile is installed at the bottom end of the hydraulic column, and fastening bolts are vertically threaded on the left and right sides of the assembly pile.

[0010] Preferably, one end of the connecting shaft frame away from the connecting shaft frame is fixedly connected to the bottom of the support frame, and the bottom end of the hydraulic column is vertically fixed to the middle inside of the assembly pile.

[0011] Preferably, the winding frame and the mounting frame are connected by welding, and the connecting ring is buckled inside the connecting ring.

[0012] Preferably, the base assembly includes a stabilizing seat, a connecting pile and fixing bolts. A connecting pile is horizontally installed in the middle of the stabilizing seat, and fixing bolts are vertically threaded on the left and right sides of the stabilizing seat.

[0013] Preferably, the stabilizing seat and the mounting frame are fixedly connected to each other by an embedded welding structure, and the fixing bolts are symmetrically arranged at the front and rear ends on one side of the stabilizing seat.

[0014] Compared with the prior art, the beneficial effect of the present utility model is as follows: for the wind resistance adjustment device of the photovoltaic flexible support, through the structural setting of the connecting ring and the traction ring at the bottom of the left and right ends of the supporting bracket, the traction assembly can be connected to the supporting bracket. When the lifting column adjusts the inclination angle of the supporting bracket connected at the top within a certain range, the traction assemblies installed at the left and right ends of the mounting frame will operate in coordination, so as to provide effective structural traction to the whole supporting bracket, thereby realizing the stability of the structure of the photovoltaic support connected to the whole device by the supporting bracket, and thus minimizing the influence caused by wind as much as possible;

[0015] For the wind resistance adjustment device of the photovoltaic flexible support, a traction assembly is provided. The traction ring at the end of the metal cable is sleeved with the connecting ring at the bottom of the rotating pile, so that the supporting bracket and the traction assembly can be connected to each other. When the servo motor operates, it will drive the winding frame connected to its power output end to rotate axially in the horizontal direction. Thus, under the telescopic adjustment of the structure of the lifting column, when the supporting bracket adjusts the inclination angle within a certain range, the traction assemblies symmetrically installed on the left and right can, through the operation of the structure, respectively perform effective structural traction at the bottom ends of the supporting bracket, and at the same time use the tensioning of the metal cable connecting the support frame and the winding frame to further ensure the stability of the structure of the supporting bracket and prevent unnecessary structural shaking;

[0016] The wind-resistant adjustment device of the flexible photovoltaic support is provided with lifting columns. The lifting columns are vertically and symmetrically installed on the left and right sides of the bottom of the support bracket. By using the telescopic structure of the hydraulic columns, the support bracket can be adjusted in height within a certain range. By using the above structure, on the one hand, it is convenient for operators to fix the photovoltaic support on the top surface of the connection frame, and on the other hand, the overall device and the photovoltaic support can be adjusted in height to a certain extent according to needs. In addition, by using the mobility of the connecting shaft frame connected between the support frame and the hydraulic columns and cooperating with the independent operation adjustment of the two groups of hydraulic columns, the photovoltaic support can be flexibly tilted at different angles within a certain range, thus ensuring the flexibility of the device structure to meet different usage requirements.

Detailed Description of the Preferred Embodiments

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: an anti-wind adjustment device for a photovoltaic flexible support, which includes a support bracket 1 and a traction assembly 4. Lifting columns 2 are vertically and symmetrically installed at the left and right bottoms of the support bracket 1, and an installation frame 3 is horizontally connected and installed at the bottom of the lifting column 2. The traction assembly 4 is fixedly installed at the tops of the left and right ends of the installation frame 3, and the bottoms of the left and right ends of the installation frame 3 are connected with a base assembly 5. The traction assembly 4 includes a winding frame 401, a servo motor 402, a metal cable 403 and a traction ring 404. A servo motor 402 is horizontally installed on one side of the winding frame 401, and a metal cable 403 is wound on the middle surface of the winding frame 401. One end of the metal cable 403 away from the winding frame 401 is fixed with a traction ring 404. The winding frame 401 and the installation frame 3 are connected by welding, and the connecting ring 104 is buckled inside the connecting ring 104.

[0024] When using the anti-wind adjustment device for the photovoltaic flexible support, as Figure 1 and Figure 4 shown, the base assembly 5 includes a stabilizing seat 501, a connecting pile 502 and fixing bolts 503. A connecting pile 502 is horizontally installed at the middle end of the stabilizing seat 501, and fixing bolts 503 are vertically and threadedly installed on the left and right sides of the stabilizing seat 501. The stabilizing seat 501 and the installation frame 3 are connected and fixed by an embedded welding structure, and the fixing bolts 503 are symmetrically arranged at the front and rear ends on one side of the stabilizing seat 501. First, through the stabilizing seat 501 connected with the connecting pile 502, the installation frame 3 is horizontally placed on the set installation structure surface. After confirming the installation position, the fixing bolts 503 can be used to structurally fix the entire installation frame 3 with the traction assembly 4 and the base assembly 5.

[0025] Meanwhile, the supporting bracket 1 includes a connecting bracket 101, a supporting frame 102, a rotating pile 103 and a connecting ring 104. The bottom of the connecting bracket 101 is connected with the supporting frame 102, and the rotating piles 103 are installed at both the left and right ends of the bottom of the supporting frame 102. Moreover, the connecting ring 104 is hung at the bottom of the rotating pile 103. The connecting bracket 101 and the supporting frame 102 are connected by welding, and the connecting ring 104 is sleeved inside the bottom end of the rotating pile 103. The lifting column 2 includes a hydraulic column 201, a connecting shaft frame 202, an assembly pile 203 and a fastening bolt 204. The top of the hydraulic column 201 is installed with the connecting shaft frame 202, and the bottom end of the hydraulic column 201 is installed with the assembly pile 203. Moreover, the fastening bolts 204 are vertically threadedly installed on both the left and right sides of the assembly pile 203. One end of the connecting shaft frame 202 away from the connecting shaft frame 202 is fixedly connected to the bottom of the supporting frame 102, and the bottom end of the hydraulic column 201 is vertically fixed inside the middle of the assembly pile 203. Then, the entire lifting column 2 is butt-jointed with the mounting frame 3 structure through the assembly pile 203, and the fastening bolts 204 are sequentially screwed vertically into the internal cavities of the assembly pile 203 and the mounting frame 3, so as to fixedly connect the lifting column 2 and the mounting frame 3, ensuring the structural stability of the supporting bracket 1 connected to the top of the lifting column 2.

[0026] After that, the photovoltaic bracket is connected to its structure through the use of the connecting bracket 101, facilitating the subsequent laying of photovoltaic modules. When it is necessary to adjust the supporting bracket 1, only by the telescopic structure of the hydraulic column 201, the structural lifting adjustment of the supporting bracket 1 can be quickly realized. At the same time, with the cooperation of the structural mobility of the connecting shaft frame 202 and the separate operation of the two hydraulic columns 201, the overall inclination adjustment of different angles of the supporting bracket 1 can be realized, ensuring the windward surface inclination angle of the photovoltaic device.

[0027] Meanwhile, start the servo motor 402, and drive the winding frame 401 connected thereto to rotate horizontally axially by the operation of the servo motor 402, so as to wind and unwind the metal cable 403 used to connect the supporting bracket 1 and the traction assembly 4. Under the pulling of the metal cable 403, the connecting ring 104 at the bottom of the rotating pile 103 is driven by the traction ring 404, so that the metal cable 403 will be appropriately unwound in cooperation with the different lifting angles at both ends of the entire supporting bracket 1, and the metal cable 403 is tightened to ensure the structural stability of the supporting bracket 1.
