DETAILED DESCRIPTION

[0035] The core of this application is to provide a photovoltaic system to improve the light utilization rate of the photovoltaic system.

[0036] Another core of the present application is to provide a photovoltaic system control method for the above photovoltaic system.

[0037] 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.

[0038] Agricultural and animal husbandry photovoltaic greenhouses and various forms of home sunrooms all use the roof area to generate electricity and generate income, and also have the function of sheltering from wind and rain. They do not occupy the ground and space, and will not affect the nature of land use, thereby achieving the effect of saving land resources.

[0039] Traditional photovoltaic modules and support structures located on the ceiling are usually fixed and cannot be adjusted in angle, so the light received by the photovoltaic modules remains unchanged, resulting in unsatisfactory power generation efficiency. At the same time, lighting and ventilation are difficult to meet the requirements of different sites.

[0040] For this reason, Figure 1As shown, the embodiment of the present application discloses a photovoltaic system, including a scaffolding body 10 and a shield 20. A movable plate 21 that can be opened and closed is used to ensure sufficient light exposure within the scaffolding. At the same time, water stains such as snow or rain can be drained through a water channel 40 between two adjacent shields 20, preventing water stains from accumulating on the photovoltaic modules 22 and the light-transmitting plate 23, which would affect the light transmission effect and power generation efficiency, thereby improving the light utilization rate of the photovoltaic system.

[0041] The following will be combined Figures 1 to 7 The photovoltaic system disclosed in the embodiments of the present application is specifically explained and illustrated.

[0042] Among them, such as Figure 1 and Figure 2 As shown, a plurality of shielding plates 20 can be used, and each shielding plate 20 is installed on the top of the scaffolding body 10 to form the roof of the scaffolding body 10, thereby achieving the effect of shielding from wind and rain. In addition, the shielding plates 20 can adopt at least one of the photovoltaic components 22 and the light-transmitting plates 23, that is, the shielding plates 20 can all adopt photovoltaic components 22 that can generate electricity, or all adopt light-transmitting plates 23 that can transmit light. Of course, some of the shielding plates 20 can adopt photovoltaic components 22, and the rest of the shielding plates can adopt light-transmitting plates 23, thereby achieving the dual effects of both power generation and light transmission. At the same time, as Figure 2 As shown, at least one of the shields 20 can be equipped with a movable panel 21 that can be opened and closed. That is, the number of movable panels 21 in each shield 20 can be one, two, three, or more. Of course, all shields 20 can also be movable panels 21. A driving and adjusting mechanism 30 is provided between the movable panel 21 and the scaffolding body 10 to drive the movable panel 21 to open and close. The driving and adjusting mechanism 30 can drive the movable panel 21 to open and close, thereby enabling the movable panel 21 to be opened and closed according to actual needs, thereby ensuring that more light is provided within the scaffolding body 10 and improving the light utilization rate of the photovoltaic system. It should be noted that the light-transmitting panel 23 can be equipped with filters of different colors, thereby matching different light color requirements according to different usage requirements.

[0043] In addition, if Figure 3 and Figure 4 As shown, a water channel 40 is provided between two adjacent shielding plates 20 so that rainwater, snow water and other water stains can be discharged through the water channel 40 to prevent water stains from accumulating on the photovoltaic components 22 and the light-transmitting plate 23, affecting the light transmission effect and power generation efficiency.

[0044] In some embodiments, as Figure 1 and Figure 2As shown, the scaffolding body 10 may be composed of a scaffolding frame 16 and purlins 17 overlapped on the top of the scaffolding frame 16, and the shielding plate 20 may be installed on the purlins 17 on the top of the scaffolding frame 16. The scaffolding frame 16 may include a plurality of columns and a plurality of triangular trusses connected to the tops of the columns, wherein the columns are distributed in at least two rows, and the triangular trusses are installed in parallel on the tops of two adjacent rows of columns to form the scaffolding frame 16. At the same time, the adjacent triangular trusses are connected by a plurality of parallel purlins 17, thereby improving the overall stability of the scaffolding body 10 and facilitating the installation of the shielding plate 20.

[0045] In some embodiments, as Figure 1 As shown, the scaffolding body 10 can be one or multiple scaffolding frames 16 connected to each other. Figure 2 As shown, the scaffolding body 10 can also adopt two, three or more scaffolding frames 16 according to actual needs, and the shielding plate 20 is adapted to the scaffolding body 10, that is, each scaffolding body 10 is covered with a shielding plate 20. Figure 1 As shown, the movable panels 21 can be respectively distributed on both sides of the triangular truss, so that the shielding panels 20 on both sides of the ridge of the scaffolding body 10 can be opened and closed, thereby ensuring that there is more light in the scaffolding body 10 and improving the light utilization rate of the photovoltaic system. Of course, according to actual needs, the movable panels 21 can also be located on only one side of the triangular truss. Figure 2 As shown, when the scaffolding body 10 uses multiple scaffolding frames 16, the movable panels 21 of some scaffolding frames 16 can be distributed on both sides of the triangular truss, and the movable panels 21 of some scaffolding frames 16 can be located only on one side of the triangular truss.

[0046] In some embodiments, as Figure 4 As shown, a support base 43 is connected to the water channel 40 via welding or bolts, thereby supporting the shield 20 and securing it to the shield 20 with copper hoops, bolts, or other fasteners. Furthermore, the support base 43 can also be connected to the purlins 17 of the scaffolding body 10 via welding or bolts, ensuring a secure connection between the shield 20 and the scaffolding body 10. Furthermore, to ensure a tight seal, a support seal 44 can be provided between the support base 43 and the shield 20. The support seal 44 can be made of a rubber sealing strip or sealant, thereby filling the gap between the support base 43 and the shield 20 to ensure a tight seal and prevent water from entering the scaffolding body 10. It should be noted that in order to ensure that the water stains on the baffle 20 can flow into the water guide groove 40, the upper surface of the baffle 20 must not be lower than the slot position of the water guide groove 40, so that the water stains on the baffle 20 can flow into the water guide groove 40 and be discharged from the water guide groove 40.

[0047] In some embodiments, as Figure 1 and Figure 2 As shown, the scaffolding body 10 may be formed with a ridge 11 and an eaves 12. Figure 5 As shown, a top gutter 12 capable of rotating about the ridge 11 may be provided on at least one side of the ridge 11. The top gutter 12 may be provided on one side of the ridge 11, or on both sides of the ridge 11. At the same time, at least one movable panel 21 is connected to the top gutter 12. Specifically, there may be one, two, three, or more movable panels 21 connected to the top gutter 12, so that the drive adjustment mechanism 30 can drive the movable panels 21 to rotate about the ridge 11. Furthermore, a connection seal 13 is provided between the top gutter 12 and the ridge 11. The connection seal 13 may be made of a rubber sealing strip or sealant, etc., so that the connection seal 13 can be filled in the gap between the top gutter 12 and the ridge 11 to ensure a sealing effect and prevent water stains from entering the scaffolding body 10.

[0048] In some embodiments, as Figure 5 As shown, a C-shaped bayonet can be formed on at least one side of the roof ridge 11, and a C-shaped plug that can be inserted into the C-shaped bayonet can be connected to one side of the top water tank 12 and can rotate within the C-shaped bayonet. Furthermore, at least one of the C-shaped plug and the C-shaped bayonet can be elastically deformable, that is, the C-shaped plug can be elastically deformable, or the C-shaped bayonet can be elastically deformable, or both can be elastically deformable, to ensure that the C-shaped plug can be inserted into the C-shaped bayonet and prevent it from falling out.

[0049] In some embodiments, as Figure 2 As shown, a water gutter 15 can be provided at the eaves 14 of the scaffolding body 10. Figure 4 As shown, the water channel 40 may include a first channel 41 arranged along a first direction and a second channel 42 arranged along a second direction. The first direction may be along the slope of a sloping roof, and the second direction may be parallel to the ridge. This means the first and second directions are perpendicular to each other. Of course, the first and second directions may also intersect and be non-perpendicular. The second channel 42 is connected to the first channel 41, and the first channel 41 is connected to the water gutter 15. This allows water to be directed through the first and second channels 41, 42, to the water gutter 15, where it can then be discharged. This allows the water to be concentrated in one place, preventing the occurrence of random water flow.

[0050] In some embodiments, as Figure 3As shown, a sealing structure 50 is connected between the open side of the movable panel 21 and the fixed side of the adjacent shield 20. The sealing structure 50 may include a sealing cover 51 disposed on the open side of the movable panel 21 and a sealing strip 52 disposed on the fixed side of the adjacent shield 20. When the movable panel 21 is closed, the sealing cover 51 abuts against and compresses the sealing strip 52, thereby ensuring a seal between the movable panel 21 and the adjacent shield 20. At this point, the first water channel 41 on one side of the movable panel 21 communicates with the first water channel 41 on the side of the adjacent shield 20, thereby diverting water stains to the water gutter 15 for discharge through the water gutter 15. It should be noted that the baffle 20 adjacent to the movable plate 21 can be a baffle 20 fixed on the scaffolding body 10, or a movable plate 21. At the same time, the sealing structure 50 can be arranged between the adjacent movable plates 21 and the baffle 20 along the first direction, or between the adjacent movable plates 21 and the baffle 20 along the second direction. This article will not elaborate on this.

[0051] In some embodiments, as Figure 3 As shown, the drive adjustment mechanism 30 may include a drive member 31 and a push rod 32 in transmission connection with the drive member 31. The drive member 31 may be mounted on the scaffolding frame 16 of the scaffolding body 10 via a base 33. The push rod 32 may be connected to the water channel 40, so that the drive member 31 drives the push rod 32 to extend and retract, thereby opening and closing the movable panel 21 connected to the water channel 40. It should be noted that the drive member 31 may be a cylinder, a motor, or other drive mechanism, and this is not limited herein.

[0052] In some embodiments, as Figure 3 As shown, the driving member 31 can be a motor, and a transmission wheel 34 capable of transmitting power is provided between the driving member 31 and the push rod 32. The motor drives the transmission wheel 34 to rotate, and the transmission wheel 34 then drives the push rod 32 to extend and retract, thereby converting the rotation of the motor into the extension and retraction of the push rod 32 through the transmission wheel 34. The connection between the push rod 32 and the transmission wheel 34 can adopt, but is not limited to, a rack and pinion structure, and can also adopt a worm gear and worm structure. Of course, other transmission methods can also be used, which are not limited herein.

[0053] In the above embodiment, the driving and adjusting mechanism 30 can be arranged on one side of the ridge of the scaffolding body 10 according to actual needs. The driving and adjusting mechanism 30 can also be arranged on both sides of the ridge. Of course, the driving and adjusting mechanism 30 can also be arranged in multiple rows on the same side of the ridge.

[0054] In some embodiments, as Figure 3As shown, a damper 60 can be installed between the movable plate 21 and the scaffolding body 10 to reduce the impact of strong winds on the overall vibration of the photovoltaic structure and improve the stability of the photovoltaic system structure. Multiple dampers 60 can be used, and each damper 60 can be located on both sides of the ridge of the roof 11, or only on one side of the ridge 11. Of course, multiple rows of dampers 60 can also be distributed on the same side of the ridge 11. Furthermore, one end of the damper 60 can be connected to the purlin 17 of the scaffolding body 10, and the other end of the damper 60 can be connected to the first water tank 41, thereby reducing the impact of overall vibration of the photovoltaic structure.

[0055] In some embodiments, the photovoltaic system may also include an intelligent monitoring module capable of collecting environmental parameters and an early warning device capable of issuing early warning reminders, wherein the environmental parameters may include at least one of weather conditions, ambient temperature, wind and snow conditions, rainfall conditions, light intensity, and gas concentration, and the intelligent monitoring module can make logical judgments based on the preset values of the environmental parameters, that is, the input values combined with the usage requirements, so as to issue instructions to the controller that controls the drive adjustment mechanism 30, and adjust the inclination angle of the movable panel 21 accordingly to realize intelligent functions such as ventilation, lighting, and temperature control.

[0056] In some embodiments, the intelligent monitoring module may include an NCU intelligent communicator, so that data transmitted by various sensors such as wind speed, temperature, light, carbon dioxide concentration, etc. can be received in real time through the NCU intelligent communicator. According to the requirements of specified input, for example: priority is given to ensuring that the temperature is greater than the X value, and secondly to ensuring the power generation), the real-time power generation data of the photovoltaic system is referred to and combined with meteorological data to complete the logical judgment operation of the corresponding parameters and send corresponding instructions to the controllers at each location.

[0057] like Figure 6 As shown, when the controller at each location receives the command from the NCU intelligent communicator, it controls the photovoltaic system structure to complete the command operation and feeds back the status of the photovoltaic system structure after the command is in place to the NCU intelligent communicator; or, the abnormal status of the photovoltaic system structure that is not in place is fed back to the NCU intelligent communicator, and the corresponding early warning alarm is issued through the early warning device. The final data results are presented in real time on the intelligent monitoring and control platform.

[0058] Among them, the intelligent monitoring and control platform has certain continuity and time requirements for monitoring input demand. In order to ensure the safe operation of the photovoltaic system and avoid frequent switching of operating states, it can be set to trigger a response when the duration is longer than A to lock the limit value, and to release the limit value when the duration is longer than B. Figure 7 As shown in the figure. Furthermore, the intelligent monitoring module also features fault alarms, extreme situation warnings, and manual control to facilitate adjustment and maintenance of the photovoltaic system. It should be noted that the control method described above is not limited to this one and can be adjusted based on actual conditions.

[0059] The photovoltaic system disclosed in the embodiments of the present application comprises a plurality of shields 20 mounted on the top of a scaffolding body 10. The shields 20 can be formed of at least one of photovoltaic modules 22 and light-transmitting panels 23. At least one of the shields 20 is a movable panel 21 that can be opened and closed. A drive and adjustment mechanism 30 is provided between the movable panel 21 and the scaffolding body 10. This mechanism can be used to drive the movable panel 21 to open and close, thereby ensuring sufficient light within the scaffolding. Furthermore, a water channel 40 between adjacent shields 20 drains away water such as snow or rain, preventing it from accumulating on the photovoltaic modules 22 and light-transmitting panels 23 and affecting light transmission and power generation efficiency.

[0060] The photovoltaic system disclosed in the embodiment of the present application can ensure that there is more light in the scaffolding through the movable plate 21 that can be opened and closed and adjusted. At the same time, water stains such as snow water or rain water can be discharged through the water guide trough 40 between two adjacent shielding plates 20, avoiding water stains from accumulating on the photovoltaic components 22 and the light-transmitting plates 23, affecting the light transmission effect and power generation efficiency, thereby improving the light utilization rate of the photovoltaic system.

[0061] The present application also discloses a photovoltaic system control method. This method, which is specific to the photovoltaic system disclosed in the above embodiments, combines all the technical advantages of the aforementioned photovoltaic systems and is not further described herein. The photovoltaic system control method may include the steps of acquiring environmental parameters, issuing action instructions, and actuating a regulating mechanism. The photovoltaic system control method will be specifically explained and illustrated below.

[0062] Step A, obtaining environmental parameters;

[0063] The NCU intelligent communicator can receive real-time environmental parameters such as weather conditions, ambient temperature, wind and snow conditions, rainfall conditions, light intensity, gas concentration, etc.

[0064] Step B, issuing action instructions;

[0065] The acquired environmental parameters are compared with the preset values of the corresponding environmental parameters, thereby sending an action instruction to the controller that controls the driving and regulating mechanism 30.

[0066] Step C, driving the regulating mechanism to operate;

[0067] The driving adjustment mechanism 30 adjusts the inclination angle of the movable plate 21 according to the instruction issued by the controller.

[0068] In some embodiments, when the temperature within the scaffolding body 10 is selected as a primary limit of 25°C to 35°C in winter, and the carbon dioxide concentration is selected as a secondary limit of 700ppm to 900ppm, the photovoltaic system's NCU intelligent communicator, upon detecting rain, snow, or other conditions outside causing a drop in temperature, can drive the adjustment mechanism 30 to adjust the tilt angle of the movable panel 21 to an appropriate angle, thereby reducing photovoltaic power generation and ensuring that the temperature and carbon dioxide concentration within the scaffolding body 10 meet the standards. If the temperature within the scaffolding body 10 is excessively high and exceeds the limits in summer, the adjustment mechanism 30 can be driven to adjust the tilt angle of the movable panel 21 to an appropriate angle to promote ventilation and cooling, while also increasing photovoltaic power generation.

[0069] In some embodiments, when the light intensity within the main trellis 10 for crops is set to 800 LUX to 1200 LUX as the primary limit and the photovoltaic power generation income as the secondary limit, when the photovoltaic power generation is too high and the NCU intelligent communicator detects that the outdoor weather is clear and the light intensity within the trellis 10 is too high, the adjustment mechanism 30 is driven to adjust the opening and closing angle of the movable panel 21 to a suitable angle, and the photovoltaic power generation is reduced to a certain extent to reduce the light intensity. When the light intensity is too low in winter due to insufficient light or rainy weather, the photovoltaic system can adjust the opening and closing angle of the movable panel 21 by driving the adjustment mechanism 30, that is, increase the opening angle of the movable panel 21 to increase light, or combine with the lighting system within the trellis 10 to make adjustments to fully utilize light resources.

[0070] In some embodiments, when the intelligent monitoring module detects an abnormal decrease in photovoltaic power generation for several days, and combined with the current normal weather conditions, it can be determined that the photovoltaic component 22 is blocked by foreign objects or needs to be cleaned in time. At this time, the early warning device can issue an early warning prompt.
