[0002] Vertical agriculture and rooftop photovoltaic technologies are now relatively mature and have been applied to a certain extent. However, the output of these technologies is relatively single, and they fail to fully utilize the multiple values of land resources, resulting in low land use efficiency. Especially in areas with limited resources, how to efficiently utilize every inch of land remains an urgent problem to be solved. In addition, although these two technologies have their own advantages in energy production and agricultural production, they have weak risk resistance in dealing with extreme weather, especially natural disasters such as typhoons and hail. This poses a certain threat to the stability and long-term reliability of the system, especially in areas where natural disasters are frequent. Therefore, how to improve the adaptability and disaster resistance of these technologies in different environments has become a key challenge for further promotion and development.

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] like Figure 1 As shown, the present application provides a technical solution: a modular photovoltaic agricultural roof structure, including a roof base 10, a track system 20, a photovoltaic module 30, a telescopic support assembly 40, a hydroponic planting column 50, and a controller 60, wherein:

[0031] The track system 20 is arranged on the upper surface of the roof base 10, the telescopic bracket assembly 40 and the hydroponic planting column 50 are arranged on the upper surface of the track system 20, the photovoltaic assembly 30 is arranged on the telescopic bracket assembly 40, and the controller 60 is electrically connected to the track system 20 to control the position adjustment of the telescopic bracket assembly 40 and the hydroponic planting column 50 relative to the roof base 10. The controller 60 is electrically connected to the telescopic bracket assembly 40 to control the height adjustment of the telescopic bracket assembly 40, and the position adjustment, height adjustment and angle adjustment include a first adjustment strategy adapted to normal weather, a second adjustment strategy adapted to typhoon weather and a third adjustment strategy adapted to hail weather.

[0032] The roof base 10 is fixedly connected or slidably connected to the load-bearing columns and / or load-bearing walls of the house. In the sliding connection example, the height of the roof base 10 relative to the ground is adjustable as a whole.

[0033] In addition, the upper surface of the roof base 10 is a photovoltaic agricultural roof structure, and the lower surface of the roof base 10 and the side walls of the house form the indoor space of the house. The indoor space can be used to place crops and work tools, etc., and the use is not limited.

[0034] It can be seen that in the embodiment of the present application, since the modular photovoltaic agricultural roof structure includes a roof base 10, a track system 20, a photovoltaic module 30, a telescopic bracket assembly 40, a hydroponic planting column 50, and a controller 60, the track system 20 is arranged on the upper surface of the roof base 10, the telescopic bracket assembly 40 and the hydroponic planting column 50 are arranged on the upper surface of the track system 20, and the photovoltaic module 30 is arranged on the telescopic bracket assembly 40. It can be seen that the photovoltaic system and the planting system are deeply integrated in the modular photovoltaic agricultural roof structure of the present application, which effectively improves the utilization efficiency of the three-dimensional space of the roof and increases the greening rate. The photovoltaic system can provide clean electricity for the building, and can also block part of the sunlight, reduce the roof temperature, and reduce water evaporation, which is beneficial to plant growth and soil water retention.

[0035] In addition, since the controller 60 in the modular photovoltaic agricultural roof structure is electrically connected to the track system 20 to control the position adjustment of the telescopic bracket assembly 40 and the hydroponic planting column 50 relative to the roof base 10, the controller 60 is electrically connected to the telescopic bracket assembly 40 to control the height adjustment of the telescopic bracket assembly 40, and the position adjustment, height adjustment and angle adjustment include a first adjustment strategy for adapting to conventional weather, a second adjustment strategy for adapting to typhoon weather and a third adjustment strategy for adapting to hail weather. In this way, the modular photovoltaic agricultural roof structure of the present application can effectively cope with the damage risks of typhoon and hail weather, and improve the disaster response intelligence level and safety of the modular photovoltaic agricultural roof structure.

[0036] In one possible example, Figure 1As shown, the telescopic support assembly 40 includes a telescopic main support 41, a main support telescopic drive mechanism 42, a telescopic sub-support 43 and a sub-support telescopic drive mechanism 44; the track system 20 includes a sliding ground rail 21, a support mounting seat 22, a planting column mounting seat 24 and a position adjustment mechanism 23; the photovoltaic assembly 30 includes a photovoltaic panel 31, a concentrator 32 and an inverter 33;

[0037] The retractable main support 41 includes a first main support joint 411, a second main support joint 412 and a third main support joint 413, the retractable sub-support 43 includes a first sub-support joint 431 and a second sub-support joint 432, and the photovoltaic panel 31 includes a first mounting base 311 and a second mounting base 312;

[0038] The sliding rail 21 is slidably connected to a bracket mounting seat 22 and a planting column mounting seat 24. The first main bracket joint 411 is provided on the bracket mounting seat 22, and the hydroponic planting column 50 is provided on the planting column mounting seat 24. The second main bracket joint 412 is connected to the first mounting seat 311, the first auxiliary bracket joint 431 is connected to the third main bracket joint 413, and the second auxiliary bracket joint 432 is connected to the second mounting seat 312.

[0039] The photovoltaic panel 31 is electrically connected to the collector 32, the collector 32 is electrically connected to the inverter 33, the inverter 33 is electrically connected to the controller 60, and the controller 60 is electrically connected to the position adjustment mechanism 23 to control the position adjustment of the bracket mounting base 22 and the planting column mounting base 24 relative to the roof base 10;

[0040] The controller 60 is electrically connected to the main support telescopic drive mechanism 42 of the telescopic main support 41 to control the height adjustment of the telescopic main support 41 , and the controller 60 is electrically connected to the auxiliary support telescopic drive mechanism 44 to control the angle adjustment of the photovoltaic panel 31 .

[0041] The specific driving modes of the main support telescopic driving mechanism 42 and the auxiliary support telescopic driving mechanism 44 may be motor driving, hydraulic driving, etc., which are not limited here.

[0042] It can be seen that in the example of the present application, since the telescopic bracket assembly 40 includes a telescopic main bracket 41, a main bracket telescopic driving mechanism 42, a telescopic sub-bracket 43 and a sub-bracket telescopic driving mechanism 44; the telescopic main bracket 41 includes a first main bracket joint 411, a second main bracket joint 412 and a third main bracket joint 413, the telescopic sub-bracket 43 includes a first sub-bracket joint 431 and a second sub-bracket joint 432, the photovoltaic panel 31 includes a first mounting seat 311 and a second mounting seat 312; the second main bracket joint 412 is connected to the first mounting seat 311, the first sub-bracket joint 431 is connected to the third main bracket joint 413, and the second sub-bracket joint 432 is connected to the second mounting seat 312; the controller 60 is electrically connected to the main bracket telescopic driving mechanism 42 of the telescopic main bracket 41 to control the height adjustment of the telescopic main bracket 41, and the controller 60 is electrically connected to the sub-bracket telescopic driving mechanism 44 to control the angle adjustment of the photovoltaic panel 31. This allows the angle of the photovoltaic panel 31 relative to the roof base 10 to be flexibly adjusted, thereby improving the intelligence and flexibility of the modular photovoltaic agricultural roof structure in controlling the photovoltaic panel 31;

[0043] In addition, since the rail system 20 includes a sliding ground rail 21, a bracket mounting seat 22, a planting column mounting seat 24 and a position adjustment mechanism 23; the photovoltaic component 30 includes a photovoltaic panel 31, a concentrator 32 and an inverter 33; the bracket mounting seat 22 and the planting column mounting seat 24 are slidingly connected to the sliding ground rail 21, the first main bracket joint 411 is arranged on the bracket mounting seat 22, and the hydroponic planting column 50 is arranged on the planting column mounting seat 24; the photovoltaic panel 31 is electrically connected to the concentrator 32, the concentrator 32 is electrically connected to the inverter 33, the inverter 33 is electrically connected to the controller 60, and the controller 60 is electrically connected to the position adjustment mechanism 23 to control the position adjustment of the bracket mounting seat 22 and the planting column mounting seat 24 relative to the roof base 10; in this way, the modular photovoltaic agricultural roof structure can intelligently control and adjust the position of the photovoltaic system components and the planting system components relative to the roof base 10, thereby improving the intelligence and flexibility of the modular photovoltaic agricultural roof structure for the position control of the photovoltaic system components and the planting system components.

[0044] In one possible example, Figure 3 As shown, the position adjustment mechanism 23 includes a synchronous belt transmission system 231, a first retractable locking pin mechanism 232 provided on the bracket mounting seat 22, and a second retractable locking pin mechanism 233 provided on the planting column mounting seat 24;

[0045] The first locking hole 23111 of the synchronous belt 2311 of the synchronous belt transmission system 231 is used to connect the first locking pin 2321 of the first locking pin retractable mechanism 232 to achieve the first position adjustment of the telescopic bracket assembly 40 relative to the roof base 10;

[0046] The second locking hole of the synchronous belt is used to connect the second locking pin of the second retractable locking pin mechanism 233 to achieve the second position adjustment of the planting column mounting seat 24 relative to the roof base 10;

[0047] The position adjustment includes a first position adjustment and a second position adjustment.

[0048] In which, the first locking hole 23111 and the second locking hole of the synchronous belt can be arranged at intervals, that is, a first locking hole 23111 is adjacent to a second locking hole, and the apertures of the first locking hole 23111 and the second locking hole can be set to be different, so that the photovoltaic system components and the planting system components will not cause position misoperation when they are controlled to adjust their positions, such as the first locking hole 23111 locking the planting column mounting seat 24, or the second locking hole locking the telescopic bracket assembly 40.

[0049] It can be seen that in the example of the present application, since the position adjustment mechanism 23 includes a synchronous belt transmission system 231, a first locking pin retractable mechanism 232 arranged on the bracket mounting seat 22, and a second retractable locking pin mechanism 233 arranged on the planting column mounting seat 24; and the first locking hole 23111 of the synchronous belt of the synchronous belt transmission system 231 is used to connect the first locking pin 2321 of the first locking pin retractable mechanism 232 to achieve the first position adjustment of the telescopic bracket assembly 40 relative to the roof base 10; and the second locking hole of the synchronous belt is used to connect the second locking pin of the second retractable locking pin mechanism 233 to achieve the second position adjustment of the planting column mounting seat 24 relative to the roof base 10; thereby, the first position adjustment and the second position adjustment can complete the position control of the telescopic bracket assembly 40 and the hydroponic planting column 50 relative to the roof base 10 controlled by the controller 60.

[0050] In a possible example, in the first adjustment strategy, the conditions that need to be met for the first position adjustment, the second position adjustment, the height adjustment, and the angle adjustment are:

[0051] The effective radiation range of the incident sunlight from the photovoltaic panel 31 to the hydroponic planting column 50 is greater than the preset range ratio; or,

[0052] The effective radiation range of the sunlight not blocked by the photovoltaic panel 31 to the hydroponic planting column 50 is greater than a preset range ratio.

[0053] The incident sunlight refers to the light transmitted through the photovoltaic panel 31 .

[0054] In this possible example, the photovoltaic panel 31 is a semi-transmissive photovoltaic component.

[0055] The sunlight that is not blocked by the photovoltaic panel 31 refers to the sunlight excluding the sunlight irradiating the photovoltaic panel 31 in all the sunlight irradiating the modular photovoltaic agricultural roof structure.

[0056] The preset range ratio may be, for example, a minimum range ratio including the area where the hydroponic plants are located, such as 80%, 85%, etc.

[0057] In the specific implementation, the operator can statistically analyze the specific empirical value intervals of the first position adjustment, second position adjustment, height adjustment and angle adjustment based on the on-site operation records, and enter the empirical value intervals into the control strategy. The operator can also calculate the empirical value intervals based on the current area's lighting data and the spatial structural relationship between the photovoltaic system components and the planting system components, and enter the empirical value intervals into the control strategy. There is no limitation here.

[0058] It can be seen that in the example of the present application, since the modular photovoltaic agricultural roof structure can actively adjust the first position and height of the photovoltaic system components, the second position and height of the planting system components, and the pitch angle of the photovoltaic panel 31, the effective radiation range of the incident sunlight of the photovoltaic panel 31 to the hydroponic planting column 50 is greater than the preset range ratio, thereby maximizing the lighting conditions of the hydroponic plants in the hydroponic planting column 50 and improving the output efficiency.

[0059] In one possible example, in the second adjustment strategy, the conditions that need to be met for the first position adjustment, the second position adjustment, the height adjustment, and the angle adjustment are:

[0060] The proportion of hollow areas in the space-occupying complex formed by the hydroponic planting column 50, the telescopic support assembly 40, and the photovoltaic panel 31 is lower than the preset hollow area ratio.

[0061] The angle of the photovoltaic panel 31 is preferably parallel to the surface of the roof base 10. The preset empty area ratio is, for example, 10%, 20%, 25%, etc.

[0062] Among them, the empty area refers to the interval set formed by the spacing areas between components in the space occupying complex. This interval set directly affects the overall wind resistance stability of the modular photovoltaic agricultural roof structure in typhoon weather. Through pre-reasonable structural design and spatial modeling analysis, the space occupying state that meets the wind resistance requirements can be set.

[0063] It can be seen that in the example of this application, since the modular photovoltaic agricultural roof structure can actively adjust the first position and height of the photovoltaic system components, the second position and height of the planting system components, and the pitch angle of the photovoltaic panel 31, the proportion of the hollow area in the space occupying complex is lower than the preset hollow area ratio, which is beneficial to improving the overall wind resistance and stability of the modular photovoltaic agricultural roof structure in typhoon weather.

[0064] In a possible example, the roof base 10 is slidably connected to the load-bearing columns and / or load-bearing walls of the house. The conditions that need to be met in the second adjustment strategy also include:

[0065] The height of the roof base 10 is lowered to a preset height so that the direct windward area of the space-occupying complex is smaller than the preset area.

[0066] The height of the roof base 10 is positively correlated with the area directly exposed to wind by the space-occupying complex. That is, the lower the height of the roof base 10, the smaller the area directly exposed to wind by the space-occupying complex. Furthermore, the minimum height requirements for the indoor space must be considered, such as not being lower than the actual height of the stored items.

[0067] It can be seen that in the example of this application, since the direct wind-exposed area of the space-occupying complex is smaller than the preset area, the overall wind-resistant stability of the modular photovoltaic agricultural roof structure in typhoon weather is further improved.

[0068] In one possible example, in the third adjustment strategy, the conditions that need to be met for the first position adjustment, the second position adjustment, the height adjustment, and the angle adjustment are:

[0069] The angle of the photovoltaic panel 31 is an inclination angle adapted to the size of hail in hail weather, and the hydroponic planting column 50 is located in the vertical projection area of the photovoltaic panel 31 relative to the upper surface of the roof base 10.

[0070] Among them, the inclination angle of the photovoltaic panel 31 relative to the horizontal plane of the roof base 10 is positively correlated with the size of the hail, that is, the larger the radius of the hail, the larger the inclination angle. By setting the inclination angle, the maximum impact force between the hail and the surface of the photovoltaic panel 31 is effectively reduced, thereby reducing the risk of the photovoltaic panel 31 being damaged.

[0071] The hydroponic planting column 50 is located in the vertical projection area of the photovoltaic panel 31 relative to the upper surface of the roof base 10 to prevent hail from hitting the plants when falling onto the roof base 10 .

[0072] It can be seen that in the example of the present application, due to the third adjustment strategy for hail weather, the angle of the photovoltaic panel 31 is an inclination angle adapted to the size of the hail in hail weather, and the hydroponic planting column 50 is in the vertical projection area of the photovoltaic panel 31 relative to the upper surface of the roof base 10. This can enhance the overall resistance of the modular photovoltaic agricultural roof structure to the risk and degree of damage caused by falling hail in hail weather.

[0073] In one possible example, Figure 1As shown, the photovoltaic assembly 30 further includes an energy storage device 34 , the inverter 33 is electrically connected to the energy storage device 34 , and the energy storage device 34 is electrically connected to the controller 60 and the hydroponic planting column 50 .

[0074] Among them, the energy storage device 34 can not only supply power to the electrical equipment in the photovoltaic system components and planting system components of the modular photovoltaic agricultural roof structure, but also supply power to other electrical equipment in the building where the modular photovoltaic agricultural roof structure is located. It can also be fed into the power grid when the overall electricity is abundant, thereby achieving grid connection and improving overall revenue benefits.

[0075] It can be seen that in the example of this application, since the photovoltaic component 30 also includes an energy storage device 34, the inverter 33 is electrically connected to the energy storage device 34, and the energy storage device 34 is electrically connected to the controller 60 and the hydroponic planting column 50, the intelligence and convenience of electricity use of the modular photovoltaic agricultural roof structure can be improved.

[0076] In one possible example, Figure 4 As shown, the hydroponic planting column 50 includes a liquid storage tank 51, a water pump 52, a column 53, a water outlet pipe 54, a planting cup 55, a liquid storage cup 56, and a return pipe 57;

[0077] The column 53 is arranged at the upper end of the liquid storage tank 51, and the side end of the column 53 is provided with a cup body bearing portion, the liquid storage cup 56 is arranged on the bearing portion, and the planting cup 55 is arranged in the liquid storage cup 56. One end of the outlet pipe 54 is connected to the water outlet of the pump body of the water pump 52, and the other end of the outlet pipe 54 is connected to the water inlet of the cup body of the liquid storage cup 56. The water outlet of the cup body of the liquid storage cup 56 is connected to one end of the return pipe 57, and the other end of the return pipe 57 is connected to the nutrient solution in the liquid storage tank 51, and the water inlet of the pump body of the water pump 52 is connected to the nutrient solution in the liquid storage tank 51.

[0078] The planting cup 55 of the hydroponic planting column 50 can be used to plant hydroponic plants.

[0079] It can be seen that in the example of this application, since the hydroponic planting column 50 includes a liquid storage tank 51, a water pump 52, a column 53, a water outlet pipe 54, a planting cup 55, a liquid storage cup 56, and a return water pipe 57; and the column 53 is arranged at the upper end of the liquid storage tank 51, the side end of the column 53 is provided with a cup body bearing portion, the liquid storage cup 56 is arranged in the bearing portion, and the planting cup 55 is arranged in the liquid storage cup 56, one end of the water outlet pipe 54 is connected to the pump body water outlet of the water pump 52, and the other end of the water outlet pipe 54 is connected to the cup body water inlet of the liquid storage cup 56, the cup body water outlet of the liquid storage cup 56 is connected to one end of the return water pipe 57, the other end of the return water pipe 57 is connected to the nutrient solution in the liquid storage tank 51, and the pump body water inlet of the water pump 52 is connected to the nutrient solution in the liquid storage tank 51, this enables the planting system components of the modular photovoltaic agricultural roof structure to realize automatic irrigation and nutrient supply, thereby improving the planting intelligence and convenience of the modular photovoltaic agricultural roof structure.

[0080] In this embodiment, the roof base 10 is fixedly connected or slidably connected to the load-bearing columns and / or load-bearing walls of the house. In the sliding connection example, the height of the roof base 10 relative to the ground is adjustable. In addition, the upper surface of the roof base 10 is a photovoltaic agricultural roof structure, and the lower surface of the roof base 10 and the side walls of the house enclose the interior space of the house. The interior space can be used to place crops and work tools, etc., and the use is not limited to a single purpose. The specific driving method of the main bracket telescopic drive mechanism 42 and the auxiliary bracket telescopic drive mechanism 44 can be motor drive, hydraulic drive, etc., and is not limited here. The preset range ratio can be, for example, the minimum range ratio including the area where the hydroponic plants are located, such as 80%, 85%, etc. The preset empty area ratio can be, for example, 10%. The smaller the empty area ratio, the stronger the overall wind resistance of the space-occupying complex, but at the same time, it is necessary to avoid excessively close squeezing of the hydroponic plants. In implementation, the size of hail, such as the radius parameter, can be detected by a visual sensor and synchronized to the controller 60. The controller 60 can use the radius parameter as a query identifier to query the pre-stored anti-hail damage tilt angle mapping relationship set to obtain the corresponding target tilt angle. The energy storage device 34 is set at the bottom of the telescopic bracket assembly 40, and each energy storage device 34 is electrically connected to the hydroponic planting column 50 that is relatively close, so that each energy storage device 34 and the hydroponic planting column 50 it powers form an independent subsystem. The range of change in the electrical connection distance caused by the position adjustment of the telescopic bracket assembly 40 and the hydroponic planting column 50 in the independent subsystem is relatively small and controllable, thereby improving the power supply stability during the position adjustment process.
