Description

Technical Field

[0001] The invention relates to the field of modular buildings, in particular to modular buildings with photovoltaic systems. Background Art

[0002] Modular buildings are made of reinforced concrete cast-in-place cabins, or metal structures, bamboo and wood structures, fiberglass structures, engineering plastic structures, or reinforced concrete structures as skeletons, which are combined with wall panels, roof panels and bottom panels to form cabins. At the same time, they integrate water, heating, electricity, and sanitary equipment and pipelines, complete interior decoration, and are factory-produced and transported to the site by vehicles for rapid installation as a whole. They are cabin-type assembled buildings, such as various Lego-style buildings, container houses, and Internet celebrity space capsules. After the existing modular buildings are installed, they can only be operated and inhabited by connecting to external water and electricity pipelines through water and electricity interfaces. In order to improve the self-sufficiency of electric energy and achieve energy conservation and emission reduction, some Modular buildings are also equipped with photovoltaic systems. For example, some container houses use photovoltaic panels to cover part or all of the roof, or use brackets to support multiple photovoltaic modules installed on the roof or eaves to form a building-integrated photovoltaic array. Currently, most modular building-integrated photovoltaic arrays are fixedly installed. Existing renewable energy power generation systems also include wind power generation systems. Wind turbines with a power generation capacity of 10 kilowatts or less are generally called small wind turbines. Small wind turbines are small in size and light in weight, so they can be installed on a single-mast tower, called a mast wind turbine. Mast wind turbines are simple, flexible and land-saving to install, and are easy to combine with modular buildings.

[0003] At present, most of the patents involving photovoltaic integrated modular buildings are about fixed installation of photovoltaic arrays on building envelope structures or additional frames, such as patent application number 2017105941221 "A container photovoltaic integrated frame building with independent power supply function", patent application number 2018211090787 "Solar prefabricated wall and modular building unit with it", patent application number 2023208248758 "Detachable photovoltaic device that can be used for the roof of temporary modular building on construction site", which also includes some fixed photovoltaic arrays that form a wind-solar complementary system with wind turbines, such as patent application number 2012207495815 "A wind-solar complementary new energy Unit container house", patent application number 2015103869634 "An environmentally adaptive modular intelligent building system suitable for the wild", patent application number 201711383289X "A modular prefabricated house"; such fixed photovoltaic arrays cannot adapt to changes in the solar altitude angle, and the real-time power generation efficiency is limited; currently, there are only a few extended photovoltaic arrays or tilt-adjustable photovoltaic arrays used for modular buildings, such as patent application number 2022208969831 "An energy-saving and environmentally friendly solar mobile container house" in which the photovoltaic array tilt angle is adjusted by driving the articulated photovoltaic components with cylinders, and patent application number 2019212848594 "A container house" The patent "An electric self-circulating new energy container house" with application number 202122615852X uses a photovoltaic array with one end hinged and the other end connected to a slider to drive the angle adjustment. The patent "A photovoltaic energy storage and utilization device for a container house" with application number 2023207511040 uses a screw to pull the horizontal movable block at the bottom of the photovoltaic panel, and the top is supported by a rod to adjust the inclination. The patent "A container house with expandable side walls" with application number 2023217708604 uses a manual or pneumatic support rod to prop up the side wall with one end hinged with a photovoltaic panel; the expansion adjustment of the above photovoltaic arrays The common disadvantage of the mode is that the center of gravity of the photovoltaic array is too far away from the rotation axis of the photovoltaic array. As the area and weight of the photovoltaic array increase, the gravitational torque increases, resulting in the drive mechanism to do more work and consume more energy. It is not suitable for large-area photovoltaic arrays that need to track the solar altitude angle to achieve optimized power generation efficiency. Although a rotating support is installed at the center of the photovoltaic array support keel in a very small number of public patents, such as the patent "An Adjustable Photovoltaic Microgrid Support System" with application number 2023231294129, the geometric center is not equal to the structural center of gravity, and there is still the problem of eccentricity between the center of gravity and the rotation axis of the photovoltaic array. In addition, the strength of the rotating support rod and universal joint used is limited, which is only suitable for small-area photovoltaic array inclination adjustment, and not suitable for large-area photovoltaic arrays with heavy weight.In addition, there are cases in existing vehicle-mounted photovoltaic systems where overlapping and retractable photovoltaic modules are arranged on the roof. However, this type of retractable and expandable photovoltaic array is a small-area photovoltaic array, and the overlapping arrangement of the retractable expansion sheets makes the illuminated surfaces of the photovoltaic modules non-coplanar, which not only reduces the installation area of ​​the photovoltaic modules at the overlapping parts, but also the shadows at the overlapping parts can significantly reduce the power generation efficiency of the photovoltaic modules. Once the area of ​​the retractable expansion sheet is increased, it will be too heavy, causing the expansion sheet to get stuck after being pulled out and difficult to retract. In summary, the existing technology lacks technical measures to return the gravity moment to zero for large-area expansion and adjustment photovoltaic arrays, resulting in excessive energy consumption in the inclination adjustment drive to overcome the gravity moment. In addition, the existing technology is very laborious for the expansion of large-area photovoltaic arrays, and requires heavy pneumatic or hydraulic devices to drive. Some even rely on multiple people to lift and then use manual poles to lift photovoltaic modules the size of the side wall of a building. The array is stretched out, or small-area photovoltaic modules are pulled out piece by piece by manpower for limited expansion, which is time-consuming and laborious; and the existing technology does not consider the adverse effects of wind loads in the expansion adjustment of large-area photovoltaic arrays, and does not incorporate the site wind environment information into the expansion adjustment control of photovoltaic arrays, which may lead to excessive energy consumption for the tilt adjustment drive to overcome the adverse wind load of large-area photovoltaic arrays; and the existing technology does not consider weather forecast information in the tilt adjustment of large-area photovoltaic arrays, and cannot make high-efficiency and low-energy one-step pre-adjustment for the optimized tilt angle of photovoltaic arrays required for different photovoltaic power generation periods under different weather conditions, so as to avoid the influence of short-term cloud changes or temporary sunlight blocking, and make frequent real-time sunlight tracking adjustments, which increases the adjustment energy consumption; and the existing building-integrated small wind power generation system has no wind environment information collection and transmission function, because it lacks the application scenario of this information. ; Summary of the invention

[0004] To solve the problem that the photovoltaic arrays of existing modular buildings with photovoltaic systems are mostly fixed and have no ability to expand and adjust the tilt angle, although the photovoltaic arrays of a small number of modular buildings can be expanded and adjusted, their weight increases as the photovoltaic area increases, and the expansion and adjustment of large-area photovoltaic arrays without gravity moment zeroing measures is very laborious and has high driving energy consumption; at the same time, when large-area pull-out expansion sheets overlap up and down, not only the installation area of ​​the photovoltaic components at the overlap is reduced, but the shadows at the overlap significantly affect the power generation efficiency of the photovoltaic components, and at the same time, they are easily stuck and difficult to retract when pulled out and expanded; in addition, the few existing photovoltaic arrays with adjustable tilt angles are small-area photovoltaic arrays. If they are enlarged into large-area photovoltaic arrays, the driving energy consumption for tilt angle adjustment is high, which significantly reduces the net power generation after deducting the power consumption for tilt angle adjustment from the photovoltaic power generation, making it difficult to meet the power demand of the modular building itself. The present invention proposes a modular building with a low-energy expansion and adjustment solar sail.

[0005] A modular building with a low-energy expansion and adjustment solar sail can be used for disaster relief, temporary residence in scenic spots or parks, and its technical purpose is to increase the area of ​​the photovoltaic array integrated in the modular building itself, especially to increase the area of ​​the main photovoltaic array with the largest area to between 1.2 times and 5.0 times the horizontal projection area of ​​the outer wall skin of the modular building, significantly improving the power generation of the photovoltaic array integrated in the modular building itself; and the photovoltaic array integrated in the modular building itself can be stored and attached to the outer surface of the modular building, reducing the outer size, making the modular building easy to transport; after being transported to the site, the photovoltaic array of the modular building is unfolded and a wind turbine is erected, and the modular building can be driven only by solar energy and wind without connecting to external power supply lines. Off-grid operation for human habitation; and the inclination angle of the large-area photovoltaic array of the modular building can be optimized and adjusted according to the geographical latitude, date and meteorological conditions of the location, which can significantly improve the real-time power generation efficiency compared with the fixed photovoltaic array; and the expansion and adjustment of the large-area photovoltaic array of the modular building is divided into two different frequency driving processes, namely low-frequency expansion and high-frequency inclination adjustment. For the high-frequency inclination adjustment, a low-energy consumption driving mechanism and control mode that fully reduces the work done by gravity and adjusts the wind resistance are adopted, which significantly reduces the driving energy consumption of the inclination adjustment of the large-area photovoltaic array; thereby, the modular building with a large-area photovoltaic array significantly improves the photovoltaic power generation capacity and significantly reduces the expansion and adjustment driving energy consumption, thereby making it easier to realize a modular building that is self-sufficient in off-grid energy and driven only by solar energy and wind power throughout the year.

[0016] The photovoltaic controller in the solar sail controller group in the modular building with low-energy expansion and regulation solar sails proposed above is connected to the battery pack through a cable, and then respectively connected to the main solar sail and the auxiliary solar sail, and the small wind turbine in the wind-sensing mast-type wind turbine, for controlling the main solar sail and the auxiliary solar sail, and the small wind turbine for multi-channel charging of the battery pack, and at the same time controlling the battery pack to discharge the load of the modular building; the modular building has one or more photovoltaic controllers, and at least one photovoltaic controller has a wind-solar complementary control function; the solar sail tilt angle adjustment controller in the solar sail controller group is connected to the main solar sail tilt angle adjustment drive mechanism and the auxiliary solar sail tilt angle adjustment drive mechanism through a wireless transmission path or control line, and at the same time receives the site wind environment information collected by the wind direction and anemometer in the wind-sensing mast-type wind turbine as part of the control information through the wind environment information wireless transmission path or control line, and at the same time the solar sail tilt angle adjustment controller also receives local weather forecast information, especially the local weather type, temperature information, cloud cover information, and solar radiation information for the next day or several days transmitted through the Internet as part of the control information, After the current effective photovoltaic power generation period ends and the site wind speed will not produce wind pressure on the surface of the main solar sail and the auxiliary solar sail that hinders their rotation, the optimized inclination angles of the main solar sail and the auxiliary solar sail in the next effective photovoltaic power generation period are preset in advance. In particular, when adjusting at a daily frequency, the optimized inclination angles of the main solar sail and the auxiliary solar sail after sunrise the next day are preset in advance at night to reduce the frequency of inclination adjustment, and complete the one-step pre-adjustment of the optimized inclination angles of the main solar sail and the auxiliary solar sail with a small inclination adjustment driving energy consumption; the solar sail deployment and storage controller in the solar sail controller group is connected to the solar sail controller group through a cable The main solar sail deployment and storage drive mechanism, the main solar sail inclination adjustment drive mechanism, the auxiliary solar sail deployment and storage drive mechanism, and the auxiliary solar sail inclination adjustment drive mechanism are connected. When the modular building is transported to the destination and in place, the solar sail deployment and storage controller is started to control the deployment of the main solar sail and the auxiliary solar sail, and the main solar sail and the auxiliary solar sail are adjusted to their respective optimized inclination angles during the current effective photovoltaic power generation period; or before the modular building is loaded and transported, or when it is necessary to prevent typhoons and rainstorms, the solar sail deployment and storage controller is started to control the storage of the main solar sail and the auxiliary solar sail.

[0017] The modular building with low-energy expansion and adjustment solar sails proposed by the present invention can achieve the following beneficial effects: the photovoltaic array of the modular building is divided into a main solar sail and a secondary solar sail, which can be unfolded and folded and can be adjusted in inclination angle, and the total area of ​​the solar sails after being fully unfolded is significantly increased, especially the area of ​​the main solar sail with the largest area is increased to between 1.2 times and 5.0 times the horizontal projection area of ​​the outer wall skin of the modular building, which significantly improves the photovoltaic power generation per unit building area of ​​the modular building; at the same time, the main solar sail and the secondary solar sail of the modular building can be folded and attached to the outer surface of the modular building cabin, reducing the overall outer dimensions and facilitating transportation; after the main solar sail and the secondary solar sail are unfolded on site, and a wind turbine with wind environment information collection and transmission function is erected, the modular building can operate without connecting to an external power supply line; at the same time, the inclination angles of the main solar sail and the secondary solar sail can also be adjusted according to specific geographical latitudes, dates, and directions. The orientation and meteorological conditions are optimized and adjusted, which significantly improves the real-time power generation efficiency compared with fixed photovoltaic arrays; the expansion and adjustment of the solar sail of the modular building is divided into two different frequency driving processes: low-frequency expansion and high-frequency tilt adjustment. The gravity moment zeroing measure is used for tilt adjustment to fully reduce the work done by gravity, and the control measure of reducing the adjustment wind resistance is adopted, thereby significantly reducing the driving energy consumption of the solar sail tilt adjustment; at the same time, in the tilt adjustment control of the main solar sail and the auxiliary solar sail, the local weather forecast information and the site wind environment information are used, and the main solar sail and the auxiliary solar sail are respectively optimized for the tilt angles required for different weather and different photovoltaic power generation periods. Pre-adjustment with high efficiency and low energy consumption is made in one step to avoid being affected by short-term cloud changes or other temporary sun blocking factors, and frequent real-time sunlight tracking adjustment increases the adjustment energy consumption; thereby, the modular building significantly improves the net capacity of photovoltaic power generation, and it is easier to achieve off-grid energy self-sufficiency driven only by solar energy and wind power throughout the year.

One of the specific implementation methods is: the traction winch or electric push rod of the main solar sail deployment and storage drive mechanism 38 or the scissor-type telescopic mechanism 386 driven by the electric push rod pulls the traction wire rope 383, so that the movable pulley 3812 is close to the fixed pulley 3811, thereby driving the main solar sail cabin. The end face of the sun-facing facade storage section frame 33 and the end face of the main solar sail cabin body shady facade storage section frame 34 are rotated and approached to the end face of the main solar sail cabin body top surface storage section frame 32, and gradually fit together, so that the illuminated surfaces of the main solar sail photovoltaic assembly 301 supported by the main solar sail cabin body sun-facing facade storage section frame 33, the main solar sail cabin body shady facade storage section frame 34 and the main solar sail cabin body top surface storage section frame 32 are unfolded to be coplanar; after the main solar sail 3 is completely flattened, the main solar sail hinge shaft is locked with the main solar sail self-locking mechanism 352 in the self-locking mechanism 35, the main solar sail hinge shaft 351 is tightened to prevent rotation and ensure the strength of the hinge point, and the main solar sail 3 is completely unfolded;The solar sail deployment and storage controller 73 is started to control the secondary solar sail deployment and storage drive mechanism 48 to deploy the secondary solar sail 4. One of the specific implementation methods is: the high-thrust electric push rod of the secondary solar sail deployment and storage drive mechanism 48 drives the secondary solar sail cabin side facade storage section frame 45 to rotate and lift around the secondary solar sail hinge shaft 46, driving the secondary solar sail inclination adjustment main shaft 43 and the secondary solar sail photovoltaic component support frame 42 to rotate and lift toward the outer far end of the side facade 13 of the modular building cabin 1; after the secondary solar sail inclination adjustment main shaft 43 reaches the required spatial position, ... The push rod stops and self-locks, so that the spatial position of the auxiliary solar sail inclination adjustment main axis 43 of the auxiliary solar sail 4 is fixed, and the auxiliary solar sail 4 is fully deployed; the solar sail deployment and storage controller 73 is started to control the main solar sail deployment and storage drive mechanism 38 so that before the main solar sail 3 is stored, the main solar sail cabin top surface storage section frame 32 is first rotated to be adjacent to the top surface of the modular building cabin 1, and then the main solar sail self-locking mechanism 352 in the main solar sail hinge axis and the self-locking mechanism 35 is unlocked, and then the solar sail deployment and storage controller 73 is started to control the storage of the main solar sail 3. One of the specific implementation methods is: controlling the main solar sail deployment and storage drive The traction winch or electric push rod or the scissor-type telescopic mechanism 386 driven by the electric push rod in the mechanism 38 retracts the stretched traction wire rope 383, and the movable pulley 3812 moves away from the fixed pulley 3811, so that the main solar sail cabin body sun-facing facade storage section frame 33 and the main solar sail cabin body shady facade storage section frame 34 rotate and turn down around the main solar sail hinge axis 351 under the action of their own gravity, and gradually return to the main solar sail hinge axis 351 suspended at the end of the main solar sail cabin body top surface storage section frame 32, respectively adjacent to the sun-facing facade 11 and the shady facade 12 of the modular building cabin 1 The storage state completes the main solar sail 3. Storing; starting the solar sail deployment and storage controller 73 to control the storage of the secondary solar sail 4. One of the specific implementation methods is: controlling the high-thrust electric push rod of the secondary solar sail deployment and storage drive mechanism 48 to drive the secondary solar sail cabin side facade storage section frame 45 to rotate and descend around the secondary solar sail hinge shaft 46, so that the secondary solar sail cabin side facade storage section frame 45, together with the secondary solar sail photovoltaic component support frame 42, are rotated to be adjacent to the side facade 13 of the modular building cabin 1, and the secondary solar sail 4 is stored; the stored secondary solar sail 4 can be fastened by the secondary solar sail storage fixing support 19 on the side facade 13 of the modular building cabin 1;Before the main solar sail 3 is tilted for the first time to optimize photovoltaic power generation, the gravity torque needs to be reset to zero. After the main solar sail 3 is fully deployed and the main solar sail self-locking mechanism 352 is locked, the main solar sail frame and the tilt adjustment drive mechanism connecting shaft or connector 371 are temporarily removed, the connection between the main solar sail tilt adjustment drive mechanism 37 and the main solar sail cabin top surface storage section frame 32 is disconnected, and then the main solar sail counterweight balance system 39 is adjusted to make the center of gravity of the main solar sail 3 completely coincide with or approximately coincide with the axis of the main solar sail tilt adjustment main shaft 36; one of the specific implementation methods is: first tilt the main solar sail 3 so that one end of the main solar sail cabin sun-facing facade storage section frame 33 is close to the ground, which is easy for personnel to operate on the ground, and then Then, the main solar sail counterweight 392 is gradually added into the main solar sail counterweight box 391 fixed at the near-ground end of the main solar sail cabin body sun-facing facade storage section frame 33, and at the same time, the tension perpendicular to the surface of the main solar sail 3 required for the pitch rotation of the main solar sail 3 is tested with a dynamometer connected to the dynamometer hanging point 393 near the ground, until the tension required for the pitch rotation of the main solar sail 3 reaches the minimum value. It can be considered that the center of gravity of the main solar sail 3 is almost coincident with the axis of the main solar sail inclination adjustment main shaft 36. At this time, the main solar sail 3 rotates mainly to overcome the friction force of the main solar sail inclination adjustment main shaft 36, and almost no work needs to be done to overcome the gravity of the main solar sail 3.

At the same time, the solar sail inclination angle adjustment controller 72 also receives local weather forecast information, especially the local weather type information, temperature information, cloud cover information, and solar radiation information for the next day or several days transmitted through the Internet as part of the control information. After the current effective photovoltaic power generation period ends, and the site wind speed does not produce wind pressure on the surface of the main solar sail 3 and the auxiliary solar sail 4 that hinders their rotation. , the solar sail inclination adjustment controller 72 presets the optimized inclination of the main solar sail 3 and the auxiliary solar sail 4 in the next effective photovoltaic power generation period in advance, especially in the night period, according to the solar sail inclination adjustment optimization control algorithm, the optimized inclination of the main solar sail 3 and the auxiliary solar sail 4 after sunrise the next day is preset in advance in one step. For example, when the weather forecast shows that the next day is a cloudy day with full clouds, the inclination of the main solar sail 3 and the auxiliary solar sail 4 is adjusted to a small inclination close to 0 degrees. When the next day is a sunny day with a certain amount of clouds, the main solar sail 3 and the auxiliary solar sail 4 are adjusted to a larger inclination related to the local geographical latitude, the current date, the azimuth of the main solar sail 3 and the auxiliary solar sail 4, the amount of clouds in the sky and the intensity of solar radiation, so that the main solar sail 3 and the auxiliary solar sail 4 use a small inclination to adjust the driving energy consumption, and produce a higher real-time photovoltaic power generation efficiency compared with the existing photovoltaic arrays of the same area and installed power. ;
