Low-carbon buildings refer to reducing the use of fossil energy, improving energy efficiency, and reducing carbon dioxide emissions throughout the entire life cycle of building materials and equipment manufacturing, construction and building use. Currently, low-carbon buildings have gradually become the mainstream trend in the international construction industry.

In the process of real estate development, energy for building heating, air conditioning, ventilation, lighting, etc. are all involved, and carbon emissions are very large. Therefore, it is necessary to build green and low-carbon residential projects as soon as possible, realize energy-saving technology innovation, establish a low-carbon emission system for buildings, pay attention to every link in the construction process, effectively control and reduce carbon emissions from buildings, and form a cyclical and sustainable development model. Ultimately, making buildings effectively save energy and reduce emissions and meet corresponding standards is the only way for China's real estate industry to embark on a healthy development.

Step 2: As the sun rotates, the position adjustment drive motor drives the rotation drive gear to continue to rotate, and the photovoltaic panel of the multi-energy utilization unit rotates with the sun to collect solar energy;

Step 3: Under night conditions, the position-adjusting driving motor drives the rotating driving gear to rotate, and the meshing connection between the rotating driving gear and the fixed inner gear ring drives the driving rotating member and the multi-energy utilization unit to rotate, so that the rainwater resource utilization component of the multi-energy utilization unit is set upward, and dew condenses on the external fixed protective filter;

Step 5: Rainwater hits the main body of the rainwater collecting plate and is diverted through the rainwater collecting trough. The rainwater flows downward through the rainwater collecting trough and accumulates in the rainwater collecting trough. As the amount of rainwater in the rainwater collecting trough increases, the force of the pressure-resisting sealing spring increases, and the upper end slot sealing block is pressed out of the rainwater inlet trough. The rainwater enters the rainwater collection trough and is discharged and collected through the rainwater drain pipe.

Compared with the prior art, the present invention has the following beneficial effects:

In the invention, under sunny conditions, the position-adjusting driving motor drives the rotating driving gear to rotate, and the meshing connection relationship between the rotating driving gear and the fixed inner gear ring drives the driving rotating member and the multi-energy utilization unit to rotate, so that the photovoltaic panel of the multi-energy utilization unit is tilted upward and eastward, and the photovoltaic panel rotates with the sun to collect solar energy; under rainy conditions, the position-adjusting driving motor drives the rotating driving gear to rotate, and the meshing connection relationship between the rotating driving gear and the fixed inner gear ring drives the driving rotating member and the multi-energy utilization unit to rotate, so that the rainwater resource utilization component of the multi-energy utilization unit is tilted upward to collect rainwater. Since sunny and rainy days do not exist at the same time in most cases, the energy utilization structure with two sets of structures is in an unused state for nearly half of the time. By integrating the two sets of energy utilization structures, the corresponding structures are used in rainy and sunny days respectively, which solves the problem that the current photovoltaic power generation structure and rainwater collection device function respectively in the case of sunshine and rain, and do not exist at the same time in most cases of sunny and rainy days, that is, only one of the two systems works under normal circumstances, and the working time cannot be complementary.

In the invention, at night or in other non-sunny and non-rainy environments, the position adjustment drive motor drives the rotating drive gear to rotate, and the meshing connection between the rotating drive gear and the fixed inner gear ring drives the driving rotating member and the multi-energy utilization unit to rotate, so that the rainwater resource utilization component of the multi-energy utilization unit is set upward, and the photovoltaic panel is set downward at this time, which can increase the protection of the photovoltaic panel itself when not in use, and avoid damage to the photovoltaic panel caused by external force impact. In addition, dew will condense on the external fixed protection filter at night instead of condensing on the photovoltaic panel, reducing the impact of temperature difference and humidity on the service life of the photovoltaic panel.

In the invention, rainwater hits the main body of the rainwater collection plate and is guided through the rainwater collection groove. The rainwater flows downward through the rainwater collection groove and accumulates in the rainwater collection groove. As the amount of rainwater in the rainwater collection groove increases, the force of the pressure blocking spring increases, and the upper end slot-inlet blocking block is pressed out of the rainwater slot-inlet, and the rainwater enters the rainwater collection groove for collection. Through the cooperation of the pressure blocking spring and the slot-inlet blocking block, the slot-inlet blocking block double blocks the rainwater slot-inlet at the lower end under the action of gravity and elastic force, preventing rainwater from leaking out of the lower end rainwater slot-inlet. The design of the leak-proof structure allows rainwater at the upper end to enter, and the lower end structure can be blocked normally. The upper and lower rainwater collection plate main bodies and the design of the rotating drive structure can match rainwater from different directions.

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Please refer to Figures 1-7. An embodiment of the present invention provides: a low-carbon building multi-energy complementary system, including a system mounting frame 3, two system mounting frames 3 are provided, the system mounting frame 3 is internally connected with a positioning and fixing frame bar 2 by bolts, the lower end of the positioning and fixing frame bar 2 is welded and fixed with a lower ground mounting plate 1, and the lower ground mounting plate 1 is installed at the target position of the roof by bolts. When the system mounting frame 3 is placed on the upper end of the outer positioning and fixing frame bar 2, there is no need to match the installation position together with the entire set of equipment, which makes the system more convenient to install and saves installation operation time.

An outer fixed vertical plate 4 is fixed to the outer side of the upper end of the system mounting frame 3 on one side, and a position adjustment driving motor 10 is installed on the upper end of the outer fixed vertical plate 4. A fixed pier 5 is fixed to the inner side of the upper end of the system mounting frame 3 on one side and the middle of the upper end of the system mounting frame 3 on the other side. The fixed pier 5 has a certain deadweight to maintain its own stability. A driving rotating member 6 is rotatably connected in the fixed pier 5. The driving rotating member 6 is composed of a fixed inner gear ring 7, a connecting rotating disk 8 and an outer T-shaped arc strip 9. The fixed inner gear ring 7, the connecting rotating disk 8 and the outer T-shaped arc strip 9 are fixedly formed. The fixed inner gear ring 7 is located on the outer side of the connecting rotating disk 8, and the outer T-shaped arc strip 9 is located at the most The outside slides in a limited position along the groove opened on the inner surface of the fixed pier 5, and a rotating ball is arranged in the groove to ensure smooth rotation; a rotating driving gear 11 is installed on the inner side of the external fixed vertical plate 4 along the output shaft end of the position adjustment driving motor 10, and the rotating driving gear 11 is located at the lower end of the fixed inner gear ring 7 and is meshed and connected with the fixed inner gear ring 7. A multi-energy utilization unit 12 is arranged between the two connected rotating disks 8. The multi-energy utilization unit 12 includes a trapezoidal external fixed block 13 and an intermediate fixed plate 14. The trapezoidal external fixed blocks 13 are located at both ends of the intermediate fixed plate 14 and are fixed to the connected rotating disk 8, so that the contact area is increased and the connection is more stable. External fixing blocks 15 are fixed at equal distances from left to right at both ends of the middle fixing plate 14. An external connection plate body 16 is fixed to the outer ends of multiple external fixing blocks 15 at one end. A photovoltaic panel 17 is installed at the outer end of the external connection plate body 16. The photovoltaic panel 17 is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials; a charging controller, an inverter and a battery are matched with it. Part of the power of the battery can be used to meet the power needs of this system. A rainwater resource utilization component 18 is installed at the outer ends of multiple external fixing blocks 15 at the other end.

Since the rotating driving gear 11 and the fixed inner gear ring 7 are meshed and connected, and the rotating driving gear 11 is at the lower end inside the fixed inner gear ring 7, the structural dimensions are different, so that the driving rotating member 6 and the multi-energy utilization unit 12 rotate at a low speed under the driving action. In addition to realizing the position conversion of the photovoltaic panel 17 and the rainwater resource utilization component 18, the angles of the photovoltaic panel 17 and the rainwater resource utilization component 18 can also be adjusted in conjunction with the sensor component, so that the photovoltaic panel 17 rotates with the sun to collect solar energy or the rainwater resource utilization component 18 adjusts the angle of the rainwater resource utilization component 18 according to the size and direction of the wind, so as to better collect rainwater.

Under sunny conditions, the position adjustment drive motor 10 drives the rotating drive gear 11 to rotate, and the meshing connection between the rotating drive gear 11 and the fixed inner gear ring 7 drives the driving rotating member 6 and the multi-energy utilization unit 12 to rotate, so that the photovoltaic panel 17 of the multi-energy utilization unit 12 is tilted upward and eastward;

As the sun rotates, the position adjustment drive motor 10 drives the rotation drive gear 11 to continue to rotate, and the photovoltaic panel 17 of the multi-energy utilization unit 12 rotates with the sun to collect solar energy.

In a rainy environment, the position adjustment drive motor 10 drives the rotating drive gear 11 to rotate, and the meshing connection between the rotating drive gear 11 and the fixed inner gear ring 7 drives the driving rotating member 6 and the multi-energy utilization unit 12 to rotate, so that the rainwater resource utilization component 18 of the multi-energy utilization unit 12 is tilted upward to collect rainwater.

At night or in other non-sunny and non-rainy environments, the position adjustment drive motor 10 drives the rotating drive gear 11 to rotate, and the meshing connection between the rotating drive gear 11 and the fixed inner gear ring 7 drives the driving rotating member 6 and the multi-energy utilization unit 12 to rotate, so that the rainwater resource utilization component 18 of the multi-energy utilization unit 12 is set upward, and the photovoltaic panel 17 is set downward at this time, which can increase the protection of the photovoltaic panel 17 itself when not in use, and avoid damage to the photovoltaic panel 17 caused by external force impact.

Furthermore, the rainwater resource utilization component 18 includes a rainwater collecting plate body 19 and an intermediate rainwater collecting box 20. The rainwater collecting plate body 19 is arranged at the inner ends of the upper and lower ends of the intermediate rainwater collecting box 20, and the rainwater collecting plate body 19 and the intermediate rainwater collecting box 20 are fixedly connected. Rainwater collecting grooves 21 are equidistantly provided on the outer end surface of the rainwater collecting plate body 19 from left to right. The inner ends of the rainwater collecting grooves 21 extend into the intermediate rainwater collecting box 20 to collect rainwater. An external fixed protective filter 22 is fixed to the outer end surface of the rainwater collecting plate body 19 along the outside of the rainwater collecting groove 21 by screws. When the rainwater resource utilization component 18 is set upward, dew will condense on the external fixed protective filter 22 at night instead of condensing on the photovoltaic panel 17, thereby reducing the influence of temperature difference and humidity on the service life of the photovoltaic panel 17; and the external fixed protective filter 22 is mainly used to block some dead branches and leaves driven by wind to avoid impurities from being introduced into the rainwater collecting groove 21.

The upper and lower end surfaces of the middle rainwater collection box 20 are provided with rainwater inlet grooves 23 along the inner ends of the rainwater collection grooves 21. A rainwater collection groove 24 is provided inside the middle rainwater collection box 20. The rainwater collection groove 24 is connected to the inside of the rainwater inlet groove 23. A rainwater discharge pipe 31 is installed on one side of the middle rainwater collection box 20, and the rainwater discharge pipe 31 is connected to the inside of the rainwater collection groove 24. An intermediate connecting horizontal plate 25 is fixed in the middle of the rainwater collection groove 24. The width of the intermediate connecting horizontal plate 25 is smaller than the internal width of the rainwater collection groove 24, so that the inside of the rainwater collection groove 24 is not divided into two spaces by the intermediate connecting horizontal plate 25, thereby reducing the setting of the discharge pipe. A fixed sleeve 26 is fixed to the upper and lower ends of the middle connecting horizontal plate 25 along the inner end of the rainwater inlet groove 23, and a telescopic inner rod 27 is telescopically connected to the fixed sleeve 26. The inner end of the telescopic inner rod 27 is provided with a sliding disk matching the inner diameter of the fixed sleeve 26 for limiting. An inner connecting sealing plate 29 is fixed to the other end of the telescopic inner rod 27, and an inlet groove blocking block 30 is fixed to the other end of the inner connecting sealing plate 29. The maximum diameter of the inlet groove blocking block 30 is greater than the diameter of the rainwater inlet groove 23, and the minimum diameter of the inlet groove blocking block 30 is less than the diameter of the rainwater inlet groove 23. The inlet groove blocking block 30 is a truncated cone structure, which is easier to perform sealing by taking advantage of its own structural shape characteristics. A pressure sealing spring 28 is installed between the inner connecting sealing plate 29 and the middle connecting horizontal plate 25 along the outside of the fixed sleeve 26 and the telescopic inner rod 27.

The outer surface of the inlet groove blocking block 30 is provided with a silicone or rubber sealing layer, which can be pressed tightly against the position of the rainwater inlet groove 23 under pressure to prevent rainwater from leaking out of the lower end rainwater inlet groove 23.

The rainwater hits the rainwater collecting plate body 19 and is diverted through the rainwater collecting groove 21. The rainwater flows downward through the rainwater collecting groove 21 and accumulates in the rainwater collecting groove 21. As the amount of rainwater in the rainwater collecting groove 21 increases, the force of the pressure-resisting sealing spring 28 increases, and the upper end groove sealing block 30 is pressed out of the rainwater inlet groove 23. The rainwater enters the rainwater collecting groove 24 and is discharged and collected through the rainwater drain pipe 31.

This system can respond to the policy requirements of energy conservation and environmental protection and collect rainwater. The collected rainwater is transported to the rainwater treatment equipment through a delivery pump for sterilization and disinfection. The rainwater is then stored in multiple storage tanks. The rainwater can be used for spraying road surfaces to reduce dust, irrigating green spaces, storing water for flushing toilets, etc.

It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
