Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0019] As Figure 1 shown, this 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. Among them, The track system 20 is disposed on the upper surface of the roof base 10. The telescopic support assembly 40 and the hydroponic planting column 50 are disposed on the upper surface of the track system 20. The photovoltaic module 30 is disposed on the telescopic support assembly 40. The controller 60 is electrically connected to the track system 20 to control the position adjustment of the telescopic support assembly 40 and the hydroponic planting column 50 relative to the roof base 10. The controller 60 is electrically connected to the telescopic support assembly 40 to control the height adjustment of the telescopic support assembly 40. And the position adjustment, height adjustment and angle adjustment include a first adjustment strategy for adapting to normal weather, a second adjustment strategy for adapting to typhoon weather, and a third adjustment strategy for adapting to hail weather.

[0020] Wherein, 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 example of the slidable connection, the height of the roof base 10 relative to the ground is integrally adjustable.

[0021] In addition, the upper surface of the roof base 10 is a photovoltaic agricultural roof structure. The lower surface of the roof base 10 and the side walls of the house enclose the indoor space of the house. The indoor space can be used to place crops, working tools, etc., and the use is not uniquely limited.

[0022] 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 support assembly 40, a hydroponic planting column 50, and a controller 60, the track system 20 is disposed on the upper surface of the roof base 10, the telescopic support assembly 40 and the hydroponic planting column 50 are disposed on the upper surface of the track system 20, and the photovoltaic module 30 is disposed on the telescopic support assembly 40. It can be seen that in the modular photovoltaic agricultural roof structure of the present application, the photovoltaic system and the planting system are deeply integrated, effectively improving the utilization efficiency of the roof three-dimensional space, increasing the greening rate. The photovoltaic system can provide clean electric energy 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.

[0023] 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 support assembly 40 and the hydroponic planting column 50 relative to the roof base 10, and the controller 60 is electrically connected to the telescopic support assembly 40 to control the height adjustment of the telescopic support assembly 40, and the position adjustment, height adjustment and angle adjustment include a first adjustment strategy for adapting to normal 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 risk of typhoon and hail weather, and improve the intelligent level and safety of the modular photovoltaic agricultural roof structure in dealing with disasters.

[0024] In a possible example, such as Figure 1As shown in the figure, the telescopic support assembly 40 includes a telescopic main support 41, a main support telescopic drive mechanism 42, a telescopic auxiliary support 43, and an auxiliary support telescopic drive mechanism 44; the track system 20 includes a sliding ground rail 21, a support mounting base 22, a planting column mounting base 24, and a position adjustment mechanism 23; the photovoltaic module 30 includes a photovoltaic panel 31, a busbar collector 32, and an inverter 33; The telescopic main support 41 includes a first main support joint 411, a second main support joint 412, and a third main support joint 413. The telescopic auxiliary support 43 includes a first auxiliary support joint 431 and a second auxiliary support joint 432. The photovoltaic panel 31 includes a first mounting base 311 and a second mounting base 312; A support mounting base 22 and a planting column mounting base 24 are slidably connected to the sliding ground rail 21. The first main support joint 411 is disposed on the support mounting base 22, and the hydroponic planting column 50 is disposed on the planting column mounting base 24; the second main support joint 412 is connected to the first mounting base 311, the first auxiliary support joint 431 is connected to the third main support joint 413, and the second auxiliary support joint 432 is connected to the second mounting base 312; The photovoltaic panel 31 is electrically connected to the busbar collector 32, the busbar 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 support mounting base 22 and the planting column mounting base 24 relative to the roof base 10; 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.

[0025] Among them, the specific driving methods of the main support telescopic drive mechanism 42 and the auxiliary support telescopic drive mechanism 44 can be motor drive, hydraulic drive, etc., and are not limited to this here.

[0026] It can be seen that in the example of the present application, since 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 telescopic main support 41 includes a first main support joint 411, a second main support joint 412 and a third main support joint 413, the telescopic 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 seat 311 and a second mounting seat 312; the second main support joint 412 is connected to the first mounting seat 311, the first sub-support joint 431 is connected to the third main support joint 413, and the second sub-support joint 432 is connected to the second mounting seat 312; 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 sub-support telescopic drive mechanism 44 to control the angle adjustment of the photovoltaic panel 31. In this way, the angle of the photovoltaic panel 31 relative to the roof base 10 can be flexibly adjusted, improving the intelligence and flexibility of the modular photovoltaic agricultural roof structure in controlling the photovoltaic panel 31; In addition, since 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 module 30 includes a photovoltaic panel 31, a busbar 32 and an inverter 33; the support mounting seat 22 and the planting column mounting seat 24 are slidably connected to the sliding ground rail 21, the first main support joint 411 is disposed on the support mounting seat 22, and the hydroponic planting column 50 is disposed on the planting column mounting seat 24; the photovoltaic panel 31 is electrically connected to the busbar 32, the busbar 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 support 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 positions of the photovoltaic system components and the planting system components relative to the roof base 10, improving the intelligence and flexibility of the modular photovoltaic agricultural roof structure in controlling the positions of the photovoltaic system components and the planting system components.

[0027] In a possible example, as Figure 3 shown, the position adjustment mechanism 23 includes a synchronous belt drive system 231, a first locking pin telescopic mechanism 232 disposed on the support mounting seat 22, and a second telescopic locking pin mechanism 233 disposed on the planting column mounting seat 24; The first locking hole 23111 of the synchronous belt 2311 of the synchronous belt drive system 231 is used to connect the first locking pin 2321 of the first locking pin telescopic mechanism 232 to achieve the first position adjustment of the telescopic support assembly 40 relative to the roof base 10; 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; The position adjustment includes a first position adjustment and a second position adjustment.

[0028] Among them, the first locking hole 23111 and the second locking hole of the synchronous belt can be arranged at intervals, that is, one first locking hole 23111 is adjacent to one second locking hole, and the apertures of the first locking hole 23111 and the second locking hole can be set differently, so that when the photovoltaic system components and the planting system components are controlled to perform position adjustment, position misoperations will not occur, 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.

[0029] It can be seen that in the example of the present application, since the position adjustment mechanism 23 includes a synchronous belt drive system 231, a first locking pin retractable 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; and the first locking hole 23111 of the synchronous belt of the synchronous belt drive 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; thus, the first position adjustment and the second position adjustment can complete the position control of the controller 60 over the telescopic bracket assembly 40 and the hydroponic planting column 50 relative to the roof base 10.

[0030] In a possible example, in the first adjustment strategy, the conditions that need to be satisfied for the first position adjustment, the second position adjustment, the height adjustment, and the angle adjustment are: The effective radiation range of the incident sunlight of the photovoltaic panel 31 on the hydroponic planting column 50 is greater than the preset range ratio; or, The effective radiation range of the sunlight not blocked by the photovoltaic panel 31 on the hydroponic planting column 50 is greater than the preset range ratio.

[0031] Among them, the incident sunlight refers to the light transmitted through the photovoltaic panel 31.

[0032] In this possible example, the photovoltaic panel 31 is a semi-transparent photovoltaic component.

[0033] Among them, the sunlight not blocked by the photovoltaic panel 31 refers to the sunlight other than the sunlight irradiating the photovoltaic panel 31 among all the sunlight irradiating the modular photovoltaic agricultural roof structure.

[0034] Among them, 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.

[0035] In specific implementation, the operator can statistically analyze the specific empirical value ranges of the first position adjustment, the second position adjustment, the height adjustment, and the angle adjustment based on the on-site operation records, and input the empirical value ranges into the control strategy. Or the operator can calculate the empirical value ranges based on the lighting data of the current area and the spatial structure relationship between the photovoltaic system components and the planting system components, and input the empirical value ranges into the control strategy. There is no limitation here.

[0036] 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 pitching angle of the photovoltaic panel 31, the effective radiation range of the incident sunlight on the photovoltaic panel 31 to the hydroponic planting column 50 is greater than the preset range ratio. In this way, the lighting conditions of the hydroponic plants in the hydroponic planting column 50 are maximally utilized, and the output efficiency is improved.

[0037] In a possible example, in the second adjustment strategy, the conditions that the first position adjustment, the second position adjustment, the height adjustment, and the angle adjustment need to meet are: The proportion of the empty area in the spatial occupancy complex formed by the hydroponic planting column 50, the telescopic support assembly 40, and the photovoltaic panel 31 is lower than the preset empty area ratio.

[0038] Among them, 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.

[0039] Among them, the empty area refers to the interval set formed by the interval areas between the components in the spatial occupancy complex. This interval set directly affects the overall wind resistance stability of the modular photovoltaic agricultural roof structure in typhoon weather. Through reasonable structural design and spatial modeling analysis in advance, a spatial occupancy state that meets the wind resistance requirements can be set.

[0040] 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 pitching angle of the photovoltaic panel 31, the proportion of the empty area in the spatial occupancy complex is lower than the preset empty area ratio, which is beneficial to improving the overall wind resistance stability of the modular photovoltaic agricultural roof structure in typhoon weather.

[0041] 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: The height of the roof base 10 is reduced to a preset height so that the direct windward area of the space occupation complex is less than the preset area.

[0042] Among them, the height of the roof base 10 is positively correlated with the direct windward area of the space occupation complex, that is, the lower the height of the roof base 10, the smaller the direct windward area of the space occupation complex. In addition, the minimum height requirement of the indoor space should be considered, such as not being lower than the actual height of the stored items, etc.

[0043] It can be seen that in the example of the present application, since the direct windward area of the space occupation complex is less than the preset area, the overall wind resistance stability of the modular photovoltaic agricultural roof structure in typhoon weather is further improved.

[0044] In a possible example, in the third adjustment strategy, the conditions that need to be satisfied for the first position adjustment, the second position adjustment, the height adjustment, and the angle adjustment are: The angle of the photovoltaic panel 31 is an inclined 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.

[0045] Among them, the inclined 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 size of the hail, such as the radius, the larger the inclined angle. By setting the inclined 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.

[0046] Among them, the hydroponic planting column 50 being in the vertical projection area of the photovoltaic panel 31 relative to the upper surface of the roof base 10 can prevent the hail from hitting the planted plants during the process of falling onto the roof base 10.

[0047] It can be seen that in the example of the present application, since the third adjustment strategy in hail weather makes the angle of the photovoltaic panel 31 an inclined 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, in this way, the risk and degree of damage of the modular photovoltaic agricultural roof structure being damaged by hail hitting in hail weather can be improved.

[0048] In a possible example, as Figure 1 shown, the photovoltaic module 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.

[0049] 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 connected to the power grid when the overall power is sufficient to achieve grid connection and improve the overall revenue efficiency.

[0050] It can be seen that in the example of this application, since the photovoltaic module 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, the power utilization intelligence and convenience of the modular photovoltaic agricultural roof structure can be improved.

[0051] In a possible example, as Figure 4 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 water pipe 57; The column 53 is arranged at the upper end of the liquid storage tank 51. A cup body bearing part is arranged on the side end of the column 53. The liquid storage cup 56 is arranged on the bearing part. 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, and the other end of the return water pipe 57 is connected into the nutrient solution in the liquid storage tank 51. The pump body water inlet of the water pump 52 is connected into the nutrient solution in the liquid storage tank 51.

[0052] Among them, the planting cup 55 of the hydroponic planting column 50 can be used to plant hydroponic plants.

[0053] 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. A cup body bearing part is arranged on the side end of the column 53. The liquid storage cup 56 is arranged on the bearing part. 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, and the other end of the return water pipe 57 is connected into the nutrient solution in the liquid storage tank 51. The pump body water inlet of the water pump 52 is connected into the nutrient solution in the liquid storage tank 51, the planting system components of the modular photovoltaic agricultural roof structure can achieve automated irrigation and nutrient supply, improving the planting intelligence and convenience of the modular photovoltaic agricultural roof structure.

[0054] 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 example of the sliding connection, the height of the roof base 10 relative to the ground is adjustable as a whole. 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 indoor space of the house. The indoor space can be used to place crops, working tools, etc., and the use is not uniquely limited. The specific driving methods of the main support telescopic driving mechanism 42 and the auxiliary support telescopic driving mechanism 44 can be motor driving, hydraulic driving, etc., which are not uniquely 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 proportion of the empty area, the stronger the overall wind resistance of the space occupancy complex. However, at the same time, it is necessary to avoid getting too close to and squeezing the hydroponic plants. In the specific implementation, the size of the hail, such as the radius parameter, can be detected by the vision sensor and synchronized to the controller 60. The controller 60 can use this radius parameter as a query identifier to query the pre-stored mapping relationship set of the anti-hail damage tilt angles, and obtain the corresponding target tilt angle. The energy storage device 34 is arranged at the bottom of the telescopic support 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 powered by it form an independent subsystem. The change range of the electrical connection distance caused by the position adjustment of the telescopic support assembly 40 and the hydroponic planting column 50 in this independent subsystem is relatively small and controllable, improving the power supply stability during the position adjustment process.

In the example of the sliding connection, the height of the roof base 10 relative to the ground is adjustable as a whole. 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, working tools, etc., and the use is not uniquely defined. The specific driving methods of the main support telescopic driving mechanism 42 and the auxiliary support telescopic driving mechanism 44 can be motor driving, hydraulic driving, etc., which are not uniquely defined here.

The controller 60 can use this radius parameter as a query identifier to query the pre-stored mapping relationship set of the anti-hail damage tilt angles, and obtain the corresponding target tilt angle. The energy storage device 34 is arranged at the bottom of the telescopic support 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 powered by it form an independent subsystem. The change range of the electrical connection distance caused by the position adjustment of the telescopic support assembly 40 and the hydroponic planting column 50 in this independent subsystem is relatively small and controllable, improving the power supply stability during the position adjustment process.
