[0031] The present invention provides a cable-suspended photovoltaic power station device, which comprises a plurality of pairs of cable base points, at least two main cables arranged in parallel, a plurality of groups of transverse supports and solar photovoltaic modules. The main cables are arranged longitudinally, and the two ends of the main cables are respectively fixed to the cable base points. The plurality of groups of transverse supports are arranged side by side, and the two ends of the plurality of groups of transverse supports are respectively connected to two adjacent main cables. The solar photovoltaic modules are fixedly installed on the plurality of groups of transverse supports. The solar photovoltaic modules can be flattened or folded and stowed. Two rows of transverse supports form a support unit, and a plurality of support units are connected in series to form a support module.

[0032] Please refer to Figure 1-Figure 11As shown, the cable-suspended photovoltaic power station device includes 4 or more paired cable base points 11, 13, at least two parallel main cables 12, a first pull rope 14, a second pull rope 15, multiple groups of cross supports 20, loose-leaf 31 and solar photovoltaic modules 30; at least two main cables 12 are arranged longitudinally, and the two ends of the main cables 12 are respectively fixed to the cable base points 11, 13; multiple groups of cross supports 20 are arranged side by side, and two rows of cross supports 20 form a support unit 21, and multiple solar photovoltaic modules 30 are fixedly installed on the multiple groups of cross supports 20 through the original hole specifications, and the solar photovoltaic modules 30 can be flattened or folded; multiple support units 21 are connected in series through hinges to form a support assembly; the two ends of multiple groups of cross supports 20 are respectively connected to two adjacent main cables 12; the cable base points 11, 13 are independent support points, and the preferred cable points can be steel towers, concrete tower columns, and concrete piers. Please refer to Figure 8 Shown is a schematic diagram of the bracket components arranged in an array.

[0033] In one embodiment of the present invention, please refer to Figure 6 , Figure 7 As shown, the two ends of the transverse bracket 20 are respectively provided with a main cable pulley 40 and a smooth spreading pulley 50, wherein the two transverse brackets 20 of the bracket unit 21 are provided with a smooth spreading pulley 50 close to the adjacent edge, and the main cable pulley 40 is provided away from the adjacent edge.

[0034] The head end, i.e., the fixed end 22, of the bracket assembly is fixed to the main cable 12, and the ends of the bracket assembly are respectively provided with a first pull rope 14 and a second pull rope 15. When the solar photovoltaic assembly 30 is unfolded, the first pull rope 14 is pulled, and the bracket assembly slides along the main cable 12, the folded bracket unit 21 is gradually unfolded, and the loose-leaf 31 is unfolded. When the first pull rope 14 reaches a preset degree, it is fixed to the cable base points 11, 13, and the second pull rope 15 is tightened until the adjacent bracket units 21 reach the same plane, and then the second pull rope 15 is fixed to the cable base points 11, 13.

[0035] In one embodiment of the present invention, the main cable pulley 40 is provided with two cable grooves, for the main cable 12 and the second pull rope 15 to pass through respectively. Figure 5 As shown, the positions of the main cable pulleys 40 at both ends of the cross support 20 are higher than the position of the flat spreader pulley 50.

[0036] Please refer to Figure 2 As shown, the solar photovoltaic assembly 30 is in a retracted and folded state, in which the wind-exposed area is minimized and the photovoltaic assembly panel surface is completely avoided and upward, so Figure 2 The state shown is the protective form of the device and the form when vegetation needs photosynthesis in the agricultural light mode, which can achieve wind resistance, wave resistance, hail resistance and healthy growth of plants.

[0037] The threading method of the second pull rope 15 of the present invention is as follows: pass through the wheel groove of the main cable pulley 40 of the first cross bracket 20 of the bracket unit 21 from the top, pass through the smooth unfolding pulley 50 from the bottom, pass through the smooth unfolding pulley 50 of the second cross bracket 20 from the bottom, pass through the wheel groove of the main cable pulley 40 from the top, and connect multiple bracket units 21 in series in sequence.

[0038] When unfolding the solar photovoltaic assembly 30, the first pull rope 14 is pulled, the bracket assembly slides along the main cable 12, the folded bracket unit 21 is gradually unfolded, and the second pull rope 15 is tightened synchronously. Please refer to Figure 3 When the first pull rope 14 reaches a certain degree of pulling, it is fixed to the cable base points 11 and 13 so that it will not retract; at this time, the adjacent photovoltaic brackets have not reached the same plane, and the second pull rope 14 is tightened until the adjacent bracket units 21 reach the same plane. Please refer to Figure 4 shown.

[0039] After the adjacent bracket units 21 reach the same plane, the second pull rope 14 is fixed to the cable base points 11 and 13 to prevent it from retracting. The bracket assembly is deployed, and is now in a normal power generation state and a protective state for excessive photosynthesis of plants in the agricultural light mode.

[0040] In one embodiment of the present invention, the device includes a first drive assembly and a second drive assembly, the first drive assembly is connected to a first pull rope, the second drive assembly is connected to a second pull rope, and the first drive assembly and the second drive assembly can be a reduction motor or a reduction winch. Specifically, the first pull rope 13 and the second pull rope 14 of the present invention can be pulled by, but not limited to, a reduction winch or a reduction motor.

[0041] The cable-suspended photovoltaic power station device and the bracket assembly of the present invention can be applied to large-span installation in mountainous areas, small- and medium-span installation in flat areas, and large-span installation in complex environments. For details, please refer to Figure 9-11 shown.

[0042] In one embodiment of the present invention, the first pull rope 13, the second pull rope 14, the traction motor and the device use an intelligent power station management system to implement a general mode, an agricultural light mode and an ocean mode.

[0043] The device of the present invention also includes an intelligent power station management system, multiple attitude sensors and a meteorological analyzer. The intelligent power station management system is pre-set with three functional modes: general mode, agricultural light mode and ocean mode. The device sets one of the modes in advance according to the user type. The intelligent power station management system in this mode performs real-time detection, data collection, control and recording on each attitude sensor and meteorological analyzer. The meteorological analyzer is composed of light, wind speed, wind direction, temperature and rain sensors. When the detection reaches the power generation meteorological parameters that meet the preset power generation requirements, the solar photovoltaic components are expanded. Please refer to Figure 3 The device also includes a cleaning component for cleaning dust or bird droppings. If the power generation is found to be decreasing compared with the previous data at the initial stage of deployment and reaches the set limit, the first row of photovoltaic modules will be sequentially cleaned through the cleaning device to clean the dust or bird droppings. This process is carried out while cleaning. After the deployment is completed, Figure 4 and Figure 5 In normal working condition, if the intelligent power station management system detects that the meteorological parameters do not trigger the self-protection and cleaning functions, the device will remain in the deployed state until protection or cleaning is required. Figure 2 The self-protection here means that after folding and stowing, the support frame, solar panel glass and wires in the photovoltaic module will be protected due to the folded state.

[0044] When the intelligent power station management system detects the current mode according to the preset value of the mode, when it detects that the device is in the agricultural light mode, it will automatically execute the light control logic according to the action process of the general mode and superimpose the vegetation photosynthesis parameters to achieve reasonable protection of different vegetation, so that the vegetation can get a better growth environment and make it easier to increase the yield of crops. Specifically, because illumination is one of the necessary parameters for light control, and because light can synthesize chlorophyll for plants, chlorophyll is very important to plants, but too much light can harm plants. In order to resist excessive sunlight, plants will consume existing chlorophyll and water, which more or less affects the growth of plants and also affects the yield of crops. In order to block and better utilize the strongest sunlight in a day, the general mode of this device is cleverly combined with an intelligent power station management system that combines a large model interface module for light agriculture and forestry crop data and a real-time collection module for meteorological information to realize various functions of the agricultural light mode; the principle process is: using the expanded state of the general mode to realize the protection function of plants in the agricultural light mode, and using the folded state of the general mode to realize photosynthesis of plants in the agricultural light mode, making the realistic version of the "intelligent planting greenhouse" possible.

[0045] When the intelligent power station management system detects that the device is in ocean mode, it will superimpose ocean meteorological parameters and balance parameters of the floating platform during the general mode operation to achieve self-balancing and Figure 2 The anti-wind and wave protection function in the state shown enables the device to be used stably under the floating platform. Specifically, the balance management of the device is performed through the general mode parameters combined with the real-time wind speed (wave height) and wind direction parameters collected in the real-time meteorological information collection module and the balance watertight compartment and balance attitude management module. When the device is in the folded state, all photovoltaic modules are concentrated on one side, which will cause the balance of the platform.

[0046] The present invention can be used in all areas of land and sea, effectively protecting photovoltaic modules from damage by extreme weather such as typhoons, waves and hail, making it possible for any common high-efficiency photovoltaic modules to control light. Since only four base points are needed for ground construction, less arable land is occupied and the original vegetation is not destroyed. The structure is light, which is convenient for construction and short construction period. It is easy to clean, maintain and has high stability and safety.
