Description

Technical Field

[0001] The present invention relates to the field of building technology, and particularly to a daylighting system for green buildings and a construction method therefor. Background Art

[0002] As a non-electric lighting system, a light duct enables a building using this system to utilize sunlight for indoor lighting during the day. Its basic principle is that outdoor natural light is collected by a daylight collector, and then transmitted through a fiber optic bundle to a diffuser, so as to evenly and efficiently irradiate natural light to places where light is needed.

[0003] Since the daylight collector is exposed to the external environment for a long time, it is difficult to keep the daylighting surface of the daylight collector clean for a long time. If there is dust accumulation, in the existing daylighting system, only manual cleaning supplies can be used to regularly clean and maintain the daylighting surface, and the use experience needs to be improved.

[0004] Therefore, it is necessary to provide a new daylighting system for green buildings. Summary of the Invention

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present invention is to provide a daylighting system for green buildings, which eliminates the need for manual cleaning and maintenance and improves the use experience.

When the mounting seat swings relative to the rotary arm to a horizontal first position, that is, the daylighting surface of the lens module is perpendicular to the outer surface of the cleaning plate, the rotation of the rotary shaft and the support can drive the daylighting surface of the lens module to collect light in all directions. When the mounting seat swings relative to the rotary arm to a vertical second position, that is, the daylighting surface of the lens module is parallel and abuts against the outer surface of the cleaning plate. In this way, when the eccentric shaft rotates, the rotary shaft rotates relative to the eccentric shaft, enabling the lens module to slide in a circle on the cleaning plate, so that the cleaning cotton can perform continuous wiping operations on the daylighting surface of the lens module.

[0007] Further, a lock is installed between the mounting base and the swing arm. When the mounting base swings relative to the swing arm to a first lateral position and the swing arm rotates downward, the cleaning plate is located below the mounting base, the hinged structure is located on the side of the lens module on the mounting base, and the center of gravity of the mounting base is located on the side of the rotation axis of the hinged structure away from the lens module.

[0008] Further, the lock is installed on the swing arm, and a resisting wall corresponding to the lock is provided on the mounting base. When the mounting base swings relative to the swing arm from a second position to the first lateral position, the lock abuts against the resisting wall.

[0014] Further, a plurality of lens modules are provided on the mounting base, and the plurality of lens modules are arranged in a coplanar manner.

[0015] To achieve the above object, the technical solution adopted by the present invention is: a construction method applicable to the above-mentioned daylighting system for green buildings, including the following steps: S1: Select an open position outside the building to install the daylighting device; S2: Install the diffuser at the position where lighting is required inside the building; S3: Connect the daylighting device and the diffuser through the optical fiber bundle.

The light collection component includes a mounting seat, a rotary arm, a lens module, an eccentric shaft, and a rotating shaft. The cleaning plate is installed on the side of the support. The eccentric shaft is rotatably fitted on the support. The rotating shaft is eccentrically and rotatably installed on the eccentric shaft. The rotary arm is connected to the eccentric shaft.

The rotation axis of the support is perpendicular to the rotation axis of the rotating shaft. In this way, when the mounting seat swings relative to the rotary arm to the first horizontal position, that is, the light collecting surface of the lens module is perpendicular to the outer surface of the cleaning plate, the rotation of the rotating shaft and the support can drive the light collecting surface of the lens module to collect light in all directions to adapt to the change of the sun's position. In addition, when the mounting seat swings relative to the rotary arm to the second vertical position, that is, the light collecting surface of the lens module is parallel and abuts against the outer surface of the cleaning plate. In this way, when the eccentric shaft rotates, the rotating shaft rotates relative to the eccentric shaft, enabling the lens module to slide in a circle on the cleaning plate, so that the cleaning cotton can perform continuous wiping operations on the light collecting surface of the lens module, completing the cleaning and maintenance of the light collecting surface of the lens module, without manual maintenance, effectively improving the user experience. In addition, the lighting collector provided by the embodiment of the present invention, by swinging the mounting seat relative to the rotary arm to the second vertical position, making the light collecting surface of the lens module parallel and abut against the outer surface of the cleaning plate, can also protect the light collecting surface of the lens module in harsh environments, avoiding damage to the light collecting surface by the external environment.

[0030] References to "one embodiment" or "an embodiment" in the course of the specification mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appearing throughout the specification do not necessarily all refer to the same embodiment. Moreover, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0031] Please refer to Figures 1 to 7 As shown, a daylighting system for a green building provided by the present invention will now be described. The daylighting system for a green building includes a daylight collector 100. The daylight collector 100 includes a support 1, a light collection assembly 2, and a cleaning plate 3. The light collection assembly 2 includes a mounting base 21, a swing arm 22, a lens module 23, an eccentric shaft 25, and a rotary shaft 26. The cleaning plate 3 is installed on the side of the support 1. The eccentric shaft 25 is rotatably fitted on the support 1. The rotary shaft 26 is eccentrically and rotatably installed on the eccentric shaft 25. The swing arm 22 is connected to the eccentric shaft 25. The lens module 23 is used to collect light. The lens module 23 is installed on the mounting base 21. The mounting base 21 and the swing arm 22 are hinged by a hinge structure 6. The rotation axis of the hinge structure 6 is perpendicular to the rotation axis of the rotary shaft 26. The rotation axis of the hinge structure 6 is parallel to the outer surface of the cleaning plate 3. The rotation axis of the rotary shaft 26 is perpendicular to the outer surface of the cleaning cotton 3. A support leg 11 is rotatably fitted on the support 1. The rotation axis of the support 1 is perpendicular to the rotation axis of the rotary shaft 26. As Figure 1 shown, when the mounting base 21 swings relative to the swing arm 22 to the first horizontal position, that is, when the light collecting surface 231 of the lens module 23 is perpendicular to the outer surface of the cleaning plate 3, the rotation of the rotary shaft 26 and the support 1 can drive the light collecting surface 231 of the lens module 23 to collect light in all directions to adapt to the change in the position of the sun. In addition, as Figure 6 shown, when the mounting base 21 swings relative to the swing arm 22 to the second vertical position, that is, when the light collecting surface 231 of the lens module 23 is parallel and abuts against the outer surface of the cleaning plate 3, when the eccentric shaft 25 rotates, the rotary shaft 26 rotates relative to the eccentric shaft 25, enabling the lens module 23 to slide in a circle on the cleaning plate 3, so that the cleaning cotton 3 can continuously wipe the light collecting surface 231 of the lens module 23, completing the cleaning and maintenance of the light collecting surface 231 of the lens module 23 without manual maintenance, effectively improving the user experience. In addition, for the daylight collector 100 provided in the embodiment of the present invention, when the mounting base 21 swings relative to the swing arm 22 to the second vertical position, making the light collecting surface 231 of the lens module 23 parallel and abut against the outer surface of the cleaning plate 3, it can also protect the light collecting surface 231 of the lens module 23 in a harsh environment, avoiding damage to the light collecting surface 231 by the external environment.

[0032] As Figure 6 shown, it can be understood that in some of the embodiments, when the mounting base 21 swings relative to the slewing arm 22 to the second vertical position, in order to enable the lens module 23 to slide around a circle on the cleaning plate 3, it can be that the eccentric shaft 25 rotates actively and the rotary shaft 26 also rotates actively, so that when the eccentric shaft 25 rotates to drive the rotary shaft 26 to be in any position, the rotary shaft 26 drives the mounting base 21 to swing and maintain a drooping state by rotating relative to the eccentric shaft 25.

[0033] As Figure 6 shown, it can be understood that in some other embodiments, when the mounting base 21 swings relative to the slewing arm 22 to the second vertical position, in order to enable the lens module 23 to slide around a circle on the cleaning plate 3, it can also be that the eccentric shaft 25 rotates actively, and the mounting base 21 naturally droops under the action of its own weight. Thus, during the active rotation of the eccentric shaft 25, the rotary shaft 26 is gently pulled by the gravity of the mounting base 21 and rotates relative to the eccentric shaft 25, so that the mounting base 21 always maintains a natural drooping state during the rotation of the eccentric shaft 25, thereby realizing the sliding of the lens module 23 around a circle on the cleaning plate 3.

[0034] As Figure 5 shown, in some of the embodiments, an eccentric shaft hole 251 is eccentrically provided on the eccentric shaft 25, and the rotary shaft 26 is rotatably installed in the eccentric shaft hole 251.

[0035] In order to make the swinging mode of the mounting base 21 relative to the slewing arm 22 simple and with low energy consumption, in some of the embodiments, a lock 24 is installed between the mounting base 21 and the slewing arm 22. When the mounting base 21 swings relative to the slewing arm 22 to the first horizontal position and the slewing arm 22 rotates downward, the cleaning plate 3 is located below the mounting base 21, the hinge structure 6 is located on the side of the lens module 23 on the mounting base 21, and the center of gravity G1 of the mounting base is located on the side of the rotation axis of the hinge structure 6 away from the lens module 23, as Figure 6As shown, when the mounting base 21 swings relative to the swing arm 22 to the first lateral position and the swing arm 22 rotates downward, due to the self-weight of the mounting base 21, the mounting base 21 has a tendency to swing downward around the hinge structure 6. At this time, the control lock 24 is unlocked, enabling the mounting base 21 to swing relative to the swing arm 22 to the second vertical position under its own weight, driving the lens module 23 to move closer to the cleaning plate 3. There is no need to additionally provide a power structure to drive the mounting base 21 to swing relative to the swing arm 22. And since the center of gravity G1 of the mounting base is on the side of the rotation axis of the hinge structure 6 away from the lens module 23, the mounting base 21 has a tendency to rotate under its own weight until the center of gravity G1 of the mounting base is directly below the hinge structure 6, so that the mounting base 21 has a tendency to rotate to make the side of the mounting base 21 where the lens module 23 is installed tilt upward. This tendency will prompt the lens module 23 to press tightly against the cleaning plate 3, thus ensuring that the lens module 23 receives excellent cleaning force exerted by the cleaning plate 3; As Figure 7 shown, in addition, since the center of gravity G1 of the mounting base is on the side of the rotation axis of the hinge structure 6 away from the lens module 23, when the mounting base 21 swings relative to the swing arm 22 to the second vertical position, at this time, the drive shaft 26 is rotated to drive the swing arm 22 upward. Since most of the mass of the mounting base 21 is on the side of the hinge structure 6 away from the support 1, the mounting base 21 will swing downward relative to the swing arm 22 away from the support 1 to the first lateral position under its own weight. Then, the control lock 24 locks the mounting base 21 and the swing arm 22, so that the mounting base 21 can be kept in the state of the first position. In this way, when the drive shaft 26 rotates to adjust the angle of the light collecting surface 231, the mounting base 21 can always be kept in the first position.

[0036] In some embodiments, the lock 24 is installed on the swing arm 22, and the mounting base 21 is provided with a resisting wall 211 corresponding to the lock 24. When the mounting base 21 swings relative to the swing arm 22 from the second position to the first lateral position, the lock 24 abuts against the resisting wall 211, thereby playing a limiting role in the swing of the mounting base 21 relative to the swing arm 22, enabling the mounting base 21 to accurately reach the first position.

[0037] In some embodiments, the lock 24 is an electric plug lock, a magnetic lock, etc.

[0038] As Figure 2As shown, in some of these embodiments, a test light source 4 is provided on the cleaning plate 3, and a light sensor is disposed inside the light-gathering surface 231 of at least one lens module 23. When the mounting base 21 swings relative to the swing arm 22 to the second vertical position such that the lens module 23 abuts against the cleaning plate 3, a light ray of a specified brightness can be emitted by the test light source 4. By receiving the light ray emitted by the test light source 4 through the light sensor, the light transmissibility of the light-gathering surface 231 of the lens module 23 can be obtained, and it can be determined in sequence whether the light-gathering surface 231 needs to be cleaned and maintained. In this way, on the one hand, compared with relying on ambient light detection, since the test light source 4 can emit a light source of a set brightness, the detection is more accurate. On the other hand, the energy consumption loss caused by ineffective cleaning is avoided, and the energy consumption of the cleaning operation can be reduced.

[0039] As Figure 2 shown, in some of these embodiments, a spray head 5 is provided on the cleaning plate 3. When the mounting base 21 swings relative to the swing arm 22 to the second vertical position such that the lens module 23 abuts against the cleaning plate 3, the light-gathering surface 231 of the lens module 23 is flushed through the spray head 5, which can reduce the number of particulate matters adhering to the light-gathering surface 231, reduce the possibility of the particulate matters scratching the light-gathering surface 231, and at the same time enhance the cleaning effect on the stubborn stains adhered to the light-gathering surface 231. The fluid sprayed by the spray head 5 can be, but is not limited to, liquids, gases, etc. The liquid can be, but is not limited to, rainwater, and the gas can be, but is not limited to, air. The power source of the spray head 5 comes from a reserve battery (not shown in the figure), and the power supply method of the reserve battery can be, but is not limited to, a solar module.

[0040] As Figure 3 shown, in some of these embodiments, the support leg 11 is used to be installed and fixed on the ground or a building. A first driver 31 for outputting the power of circular motion is installed on the support 1. The output end of the first driver 31 is in transmission connection with the support leg 11. In this way, when the first driver 31 outputs a torsional force, the support 1 can be driven to perform a circular rotation motion relative to the support leg 11.

[0041] As Figure 3 shown, in some of these embodiments, a second driver 27 for outputting the power of circular motion is installed on the eccentric shaft 25. The output end of the second driver 27 is in transmission connection with the rotating shaft 26, and the rotating shaft 26 is driven to rotate on the eccentric shaft 25 through the second driver 27.

[0042] As Figure 3 shown, in some of these embodiments, a third driver 28 for outputting the power of circular motion is installed on the support 1. The output end of the third driver 28 is in transmission connection with the eccentric shaft 25 to drive the eccentric shaft 25 to rotate on the support 1.

[0043] As Figure 1As shown, in some of these embodiments, a plurality of lens modules 23 are provided on the mounting base 21, and the plurality of lens modules 23 are arranged in a coplanar manner.

[0044] As Figure 1 As shown, in some of these embodiments, two light-receiving components 2 are provided on the support 1, and two cleaning plates 3 are provided on the support 1 corresponding to the light-receiving components 2. It can be understood that in some other embodiments not shown in the figures, there are no less than two light-receiving components 2 provided on the support 1.

[0045] The daylighting system for green buildings provided by the embodiments of the present invention further includes a diffuser and a light guide fiber bundle. One end of the light guide fiber bundle is connected to the receiving end of the lens module 23, and the other end of the light guide fiber bundle is connected to the diffuser. Thus, after the lens module 23 of the daylighting device 100 receives natural light, it is transmitted to the diffuser through the light guide fiber bundle, causing the diffuser to emit light to provide the required illumination. Specifically, a convex lens is provided on the daylighting surface 231 of the lens module 23, and one end of the light guide fiber bundle is aligned with the focal position of the convex lens. Thus, the converging effect of the convex lens is used to converge natural light to one end of the light guide fiber bundle aligned with the convex lens, and the total internal reflection of the light guide fiber bundle on the light is used to enable the light to be transmitted out from the other end. The diffuser evenly distributes the received natural light, reduces glare, and provides a soft illumination effect.

[0046] The embodiments of the present invention also provide a construction method, which is applicable to the daylighting system for green buildings provided in any of the above embodiments, and includes the following steps: S1: Select an open position outside the building to install the daylighting device 100. Specifically, fix the feet 11 of the daylighting device 100 to a stable structure at the open position. S2: Install the diffuser at the position inside the building where illumination is required. Specifically, the number of diffusers is based on; S3: Connect the daylighting device 100 and the diffuser through the light guide fiber bundle. Specifically, measure the distance between the daylighting device 100 and the diffuser, cut a light guide fiber bundle with a surplus length for connection operations, and finally organize the plurality of light guide fiber bundles.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
