[0032] In existing photovoltaic power stations, photovoltaic equipment is mostly fixedly installed on one side of a photovoltaic module, and the installation angle of the photovoltaic equipment cannot be adjusted after installation. However, the installation angle of the photovoltaic module usually needs to be adjusted according to the angle of ambient light, so that when the installation angle of the photovoltaic module changes, it cannot be well consistent with the installation angle of the photovoltaic device, resulting in the need to reserve a long active line segment between the photovoltaic device and the photovoltaic module during the assembly of the photovoltaic power station, which is not convenient for the wiring between the photovoltaic module and the photovoltaic device and the space utilization at the bottom of the bracket, reducing the practicality of the photovoltaic device. In view of the above problems, the utility model proposes a fixed frame 100.

[0033] Reference Figures 1 to 6 In an embodiment of the utility model, the fixed frame 100 includes a base frame 10, an adjusting rod 30, a first fastener 50 and a bearing frame 70. The surface of the base frame 10 is provided with a first movable groove 131; the adjusting rod 30 is telescopically arranged, and a slider 35 is arranged at one end of the adjusting rod 30, and at least a part of the structure of the slider 35 is movably arranged in the first movable groove 131; the first fastener 50 connects the base frame 10 and the slider 35; the bearing frame 70 is provided with a bearing surface for installing and fixing the photovoltaic device, and the two ends of the bearing frame 70 are rotatably connected to the base frame 10 and the adjusting rod 30 respectively, so that the bearing surface is arranged at an angle with the plane where the base frame 10 is located.

[0034] It is understandable that, affected by the light energy of the light source, the electrical energy output by the photovoltaic modules after absorbing light energy and converting it is usually relatively unstable, and the current, voltage and frequency of the electrical energy are relatively disordered. Therefore, photovoltaic power stations usually need to set up photovoltaic equipment such as rectifier boxes and inverters on one side of the photovoltaic modules, and use transmission cables to connect the photovoltaic modules and the photovoltaic equipment. Under the action of the photovoltaic equipment, the voltage stabilization, rectification and AC-DC conversion and other electrical energy regulation can be well achieved, and the output end of the photovoltaic equipment can be connected to the power grid through cables, which can well achieve stable output of electrical energy from the photovoltaic power station.

[0035] In a photovoltaic power station, the photovoltaic components can usually be set at a certain height from the ground under the support of the photovoltaic bracket, so that the photovoltaic components can better adjust the installation angle according to the illumination angle of the light source, so that the photovoltaic components can be kept facing the light source, and the light energy conversion rate of the photovoltaic components can be improved. In a photovoltaic power station, the fixed frame 100 can usually be used to install and fix the photovoltaic equipment, so that the photovoltaic equipment can be located on one side of the photovoltaic component under the support of the fixed frame 100, which is conducive to laying the transmission cable directly from one side of the photovoltaic component to the photovoltaic equipment, facilitating the wiring operation of the photovoltaic power station, and at the same time can reduce the length of the wiring and reduce the construction cost of the photovoltaic power station.

[0036] In the present application, the fixed frame 100 can be connected to the surface of the base frame 10 by setting the adjustment rod 30, and the base frame 10 and the adjustment rod 30 can be used to support the bearing frame 70 to achieve the installation and fixation of the fixed frame 100 to the photovoltaic device. The base frame 10 can be a base frame structure with a certain load-bearing capacity formed by assembling and combining steel materials. The base frame 10 can be supported and fixed in construction environments such as mountainous areas and plains by using columns; or the base frame 10 can be set in a liquid surface environment such as a lake or a pool by using floating structures such as buoys and pontoons to ensure the stable support of the fixed frame 100 to the photovoltaic device. The adjustment rod 30 can be a column structure extending vertically upward above the surface of the base frame 10. By making the adjustment rod 30 composed of at least two sections of sleeves that are sequentially sleeved, or making the adjustment rod 30 composed of at least two sections of adjustable splicing lengths, the length of the adjustment rod 30 can be telescopically set, so that the adjustment rod 30 can adjust the overall length according to the installation requirements. At this time, by setting a first movable groove 131 on the surface of the base frame 10, and setting a slider 35 on the end of the adjusting rod 30 facing the base frame 10, the slider 35 can be set corresponding to the inner size of the first movable groove 131, so that at least part of the structure of the slider 35 can be placed in the first movable groove 131, and the slider 35 can slide in the first movable groove 131 along the extension direction of the first movable groove 131, and the outer periphery of the slider 35 can abut against the inner wall of the first movable groove 131 to limit the position, which is beneficial to prevent the adjusting rod 30 from deviating during the movement on the base frame 10, avoid the adjusting rod 30 from being separated from the base frame 10, realize the directional movement of the adjusting rod 30 on the base frame 10, and ensure that the overall structure of the fixed frame 100 is stable and reliable. The bearing frame 70 can be a frame structure that is obliquely arranged above the surface of the base frame 10. The side of the bearing frame 70 facing away from the base frame 10 can form a bearing surface for installing and fixing the photovoltaic equipment, so that the bearing frame 70, the base frame 10 and the adjusting rod 30 can form a certain triangular structure, and then by rotating the two ends of the bearing frame 70 to be connected to the base frame 10 and the adjusting rod 30 respectively, the adjustment rod 30 can be moved on the base frame 10 and the length of the adjustment rod 30 can be adjusted by telescopic adjustment, so that the adjusting rod 30 can drive the bearing frame 70 to rotate around the connection point between the bearing frame 70 and the base frame 10, thereby changing the inclination angle of the bearing frame 70 and changing the angle between the bearing surface and the plane where the base frame 10 is located. After the angle between the bearing surface and the base frame 10 is adjusted by moving the adjusting rod 30, the first fastener 50 can be used to connect the slider 35 and the base frame 10 to achieve assembly and fixation of the adjusting rod 30 and the base frame 10. The first fastener 50 can be a block set on the slider 35 or a bolt or pin passing through the base frame 10 and the slider 35, etc., to ensure convenient installation between the adjusting rod 30 and the base frame 10 and achieve adjustment of the installation angle of the fixed frame 100.

[0037] The first bracket 50 is used to connect the slider 35 and the base frame 10, so that the mounting angle of the photovoltaic module can be adjusted according to the illumination angle of the light source. The first bracket 50 can be used to connect the slider 35 and the base frame 10, so that the mounting angle of the photovoltaic module can be adjusted according to the illumination angle of the light source. The first bracket 50 can be used to connect the slider 35 and the base frame 10, so that the mounting angle of the photovoltaic module can be adjusted according to the illumination angle of the light source. The first bracket 50 can be used to connect the slider 35 and the base frame 10, so that the mounting angle of the photovoltaic module can be adjusted according to the illumination angle of the light source. This is conducive to the compact wiring between the photovoltaic device and the photovoltaic module. There is no need to reserve active line segments between the photovoltaic device and the photovoltaic module to avoid pulling cables when the photovoltaic module adjusts the mounting angle. A certain amount of free space can be formed under the photovoltaic bracket and the fixed frame 100 because there is no need to store active cables. This is conducive to the storage of maintenance equipment or cleaning equipment of the photovoltaic power station, facilitates the space utilization of the photovoltaic power station, and effectively improves the practicality and reliability of the photovoltaic device.

[0038] The technical solution of the utility model is to set an adjustment rod 30 on the base frame 10, use the movement of the slider 35 in the first moving groove 131 to drive the adjustment rod 30 to move in a directional manner, and use the telescopic adjustment rod 30 to adjust the overall length of the adjustment rod 30, so that the bearing frame body rotatably connected to the adjustment rod 30 and the base frame 10 can swing on the base frame 10 as the adjustment rod 30 moves and adjusts its length, thereby changing the angle between the bearing surface and the plane where the base frame 10 is located. By using the first fastener 50 to connect and fix the adjustment rod 30 and the base frame 10, the fixed frame body 100 can well adjust the installation angle of the photovoltaic device, so that the photovoltaic device can be stably set on the fixed frame body 100 and adjust the installation angle accordingly following the angle adjustment of the photovoltaic component, so that the connecting cables between the photovoltaic device and the photovoltaic component can be arranged more compactly, thereby improving the practicality and assembly convenience of the photovoltaic device, and further improving the stability and reliability of the fixed bracket.

[0039] Reference Figures 2 to 4 In one embodiment of the utility model, the slider 35 includes an abutting portion 351 and a fixing portion 353, the abutting portion 351 is movably abutted against the surface of the base frame 10; the fixing portion 353 is connected to the side of the abutting portion 351 facing away from the adjusting rod 30, and is arranged in the first movable groove 131, and the first fastener 50 connects the fixing portion 353 and the base frame 10.

[0040] In this embodiment, the slider 35 may include an abutment portion 351 and a fixing portion 353. The abutment portion 351 may be a plate structure with a width greater than the width of the slot of the first movable slot 131, and the fixing portion 353 may be a plate structure with a height less than or equal to the slot depth of the first movable slot 131 and a width less than or equal to the slot width of the first movable slot 131, so that the slider 35 can use the abutment portion 351 to abut on the structure of the base frame 10 at the slot of the first movable slot 131, and make the fixing portion 353 move in the first movable slot 131 to achieve stable sliding of the slider 35 on the base frame 10. Under the action of the abutment portion 351, it can be helpful to prevent the fixing portion 353 from being embedded in the first movable slot 131, which may cause the slider 35 to be stuck with the inner wall of the first movable slot 131, causing the movement of the adjustment rod 30 to be blocked. At the same time, it is helpful to increase the contact area between the slider 35 and the base frame 10, and further improve the connection stability and reliability between the adjustment rod 30 and the base frame 10. Among them, the first fastener 50 can be a block or a pin clamped between the fixing part 353 and the inner wall of the first movable groove 131, or can be a pin or a bolt passing through the fixing part 353 and the base frame 10, so that the first fastener 50 can stably connect the slider 35 and the base frame 10, further improving the structural stability and reliability of the fixed frame body 100.

At this time, by setting a limiting groove 3511 on the side of the abutment portion 351 facing away from the adjusting rod 30, the size of the limiting groove 3511 can correspond to the structural setting of the channel steel or the boss of the base frame 10, so that the inner wall of the limiting groove 3511 can abut the outer peripheral side of the channel steel or the boss of the base frame 10, so that the slider 35 can utilize the limiting groove 3511 of the abutment portion 351 to limit and abut with the base frame 10, which is beneficial to further ensure the guided movement of the slider 35 on the base frame 10 and prevent the slider 35 from deviating on the base frame 10. At the same time, it is better to avoid the fixing portion 353 from being clamped with the inner wall of the first movable groove 131, thereby ensuring the stable movement of the adjusting rod 30 on the base frame 10, facilitating the adjustment of the installation angle of the fixed frame 100, and further improving the adjustment stability and reliability of the fixed frame 100.

At this time, a plurality of first connecting holes 1311 connected to the inner wall of the first movable groove 131 can be provided on the outer peripheral side of the base frame 10, and by providing a fixing hole 3531 corresponding to the size of the first connecting hole 1311 on the partial structure of the slider 35 arranged in the first movable groove 131, the adjusting rod 30 can be moved on the base frame 10 until the fixing hole 3531 is relatively connected with any first connecting hole 1311. The first fastener 50 is inserted into the first connecting hole 1311 and passes through the first connecting hole 1311 and the fixing hole 3531 to achieve a stable connection between the slider 35 and the base frame 10, thereby ensuring the connection and fixation of the adjusting rod 30 and the base frame 10, which is conducive to more convenient operation of the first fastener 50 to achieve the connection and separation of the adjusting rod 30 and the base frame 10. By sequentially arranging a plurality of first connection holes 1311 along the length direction of the first movable groove 131, the fixing hole 3531 can be connected to the first connection hole 1311 when the adjusting rod 30 is moved to a plurality of positions, thereby effectively increasing the adjustment range of the fixing frame 100 and further improving the adjustment convenience and stability of the fixing frame 100.

The fixed frame 100 can use multiple first fasteners 50 to simultaneously penetrate multiple first connection holes 1311 to connect the fixed slider 35 and the base frame 10, which is beneficial to further ensure the fastening effect of the first fasteners 50 on the slider 35 and the base frame 10, and improve the structural stability and reliability of the fixed frame 100.
