Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and in particular to a flexible photovoltaic tracking bracket. Background Art

[0002] Flexible photovoltaic tracking bracket is a photovoltaic bracket with excellent lightweight performance and high adaptability. It is made of lightweight materials, light weight, low cost, easy to carry, and reduces the pressure on the building. This bracket system can be applied to roofs of different shapes and angles, such as curved surfaces, inclined surfaces, flat surfaces, concave surfaces, etc., and the installation is simple and fast, which improves construction efficiency and reduces labor costs.

[0003] After searching, the Chinese patent application number 202320679948.9 discloses a flexible cable photovoltaic tracking bracket, including a main beam, a column, a cross beam and a load-bearing cable. The main beam can rotate circumferentially, and the cross beam is fixedly installed on the main beam perpendicular to the extension direction of the main beam. At least two parallel load-bearing cables are arranged between adjacent cross beams to allow photovoltaic modules to be installed across the load-bearing cables. The span of the flexible cable of the photovoltaic tracking bracket can be flexibly set, and the overall structure is light in weight, low in construction cost, and has good reliability.

[0004] The above patent still has the following deficiencies: (1) The tracking rope is easy to shake. Since the material of the tracking rope is usually made of steel wire rope, which has a certain toughness, the photovoltaic panels are easily affected by the wind in bad weather, causing the tracking rope to shake, which will cause the connection between the photovoltaic panels to loosen, increasing the risk of components falling off or the collapse of the entire system;

[0005] (2) The defect of inconvenient angle adjustment. Since the power generation efficiency of photovoltaic panels is closely related to the amount of solar radiation they receive, and the angle of the device cannot be adjusted according to the change in the altitude of the sun, the photovoltaic panels cannot always maintain the optimal receiving angle, especially in different seasons or different time periods of the day. This will cause the amount of solar radiation received by the photovoltaic panels to decrease, thereby reducing the power generation efficiency.

[0006] Therefore, a flexible photovoltaic tracking bracket is urgently needed to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to address the problem that the tracking rope is prone to shaking. Since the tracking rope is usually made of steel wire rope with good toughness, the photovoltaic panels are easily affected by wind in bad weather, causing the tracking rope to shake, which will cause the connection between the photovoltaic panels to loosen, increasing the risk of parts falling off or the collapse of the entire system.

[0008] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0009] A flexible photovoltaic tracking bracket includes a base plate and further includes:

[0010] The vertical poles are fixed to the top of the bottom plate, and the tops of the vertical poles are all equipped with first hinged seats;

[0011] The rotating structure is arranged on one side of the first hinge seat;

[0012] A top plate is mounted on the top of the first hinged seat, and a limiting frame is fixed on the top of the top plate;

[0013] A tensioning structure is arranged on one side of the top plate, and a tracking rope is installed on one side of the tensioning structure;

[0017] As a preferred technical solution of the present application, the hydraulic assembly includes a shell rotatably connected to both sides of a support rod, a piston sliding inside the shell, a push rod fixed to the top of the piston, and a connecting hose installed between the two shells, wherein both ends of the connecting hose are respectively connected to the chambers at the bottom of the two shells.

[0018] As a preferred technical solution of the present application, the rotating structure includes an outer shell fixed to the top ends of both sides of the vertical pole, a worm installed at the bottom end of the inner part of the outer shell, a worm wheel installed at the top end of the inner part of the outer shell, a self-locking motor installed at the bottom end of one side of the outer shell, and a rotating shaft fixed inside the worm wheel and connected to the first hinge seat.

[0019] As a preferred technical solution of the present application, the tensioning structure includes a connecting hook fixed on one side of the top plate, a connecting ring detachably installed on one side of the connecting hook, a sleeve fixed on one side of the connecting ring, a screw inserted inside the sleeve, a rotating block fixed on one side of the screw, and a connecting seat fixed on one side of the tracking rope.

[0020] As a preferred technical solution of the present application, the mounting plates are arranged in several groups along the outer side of the tracking rope, and the several groups of mounting plates are distributed at equal intervals on the outer side of the tracking rope.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] In the scheme of this application:

[0025] The middle part of the tracking rope is supported and fixed by the support rod and the connecting frame. When the tracking rope turns over, the piston squeezes the hydraulic oil inside the shell to adjust the angle of the connecting frame, thereby realizing the position fixing function of the device, facilitating the support and fixing of the tracking rope, making it difficult for the tracking rope to shake in bad weather, and at the same time making it difficult for the photovoltaic panel to shake and fall, thereby enhancing the safety of the device;

[0026] The worm is driven to rotate by the self-locking motor, so that the worm wheel drives the first hinge seat to rotate through the rotating shaft, thereby driving the top plate and the photovoltaic panel to rotate, and adjusting the placement angle of the photovoltaic panel. This realizes the angle adjustment function of the device, which is convenient for adjusting the placement angle of the photovoltaic panel, improves the power generation efficiency of the photovoltaic panel, and does not require manual operation, reduces the difficulty and cost of operation and maintenance, and enhances the functionality of the device.

[0027] The screw is moved toward the inside of the sleeve by rotating the rotating block, and at the same time the connecting seat pulls the tracking rope to tighten, so that the tracking rope remains taut, thereby realizing the tracking rope tensioning function of the device, making it easy to tension the wire rope and ensuring the normal use of the device.
