Description

Modular sunlight collection system

Technical Field

The invention relates to the technical field of sunlight collection, in particular to a modular sunlight collection system.

Background Art

Human life cannot live without sunlight. Natural sunlight improves the living environment, improves the air environment, and improves people's physical and mental health. However, there are always some places inside buildings that sunlight cannot reach, so it is very meaningful to introduce natural sunlight into the building and project it out to improve the living environment.

The growth of plants requires energy from their own photosynthesis, and the process of photosynthesis relies on sunlight. With the arrival of winter, compared with other seasons, the amount of rainfall or clouds increases due to the influence of climate, resulting in insufficient light for plants, which seriously affects their growth.

Sunlight is a natural light source, which is a mixture of light of different intensities and wavelengths. In addition to infrared and ultraviolet rays visible to the naked eye, it also contains other light waves that can participate in plant growth and metabolism. Plant supplementary lighting is developed according to the natural law of plant growth and the principle of plant photosynthesis. It can replace the sun to supplement the light for plants, and artificially regulate some light components that plants are sensitive to to promote plant growth. Ordinary lamps do not have the full spectrum characteristics absorbed by plants. If you want to use lamps to illuminate plants instead of sunlight, you must ensure that the spectrum of the lamps is the same as that of sunlight, and have light that plants absorb and utilize. Different plants absorb and utilize light differently.

The sunlight collection system refers to the process of collecting sunlight and transmitting it to the interior of a building through optical fiber and projecting it out. While providing lighting, it can also provide direct sunlight exposure for the living environment and plant growth, thereby improving the health of human life, improving the harm caused to plants by insufficient light, and improving the efficiency of indoor plant production. However, existing sunlight collectors cannot be modularly expanded as they would be with building blocks. Once the sunlight collector is produced, the number of optical lenses is fixed, and the amount of sunlight collected is also fixed, which limits the scope of application. In addition, existing technologies require that all optical lenses, all optical fiber connectors, and solar sensors must be optically coaxial. This requires an extremely complex optical debugging and optical alignment process, which is difficult to implement.

In view of this, the present invention proposes a modular sunlight collection system to solve the above technical problems.

DETAILED DESCRIPTION

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

The embodiments of the present invention provide a modular sunlight collection system, thereby solving the problems of low modular design in existing sunlight collection systems, inability to change once formed, complex optical positioning between optical lenses and solar sensors, low alignment accuracy and high cost.

In order to reduce the modular installation of the sunlight collection system and the simple optical debugging process, as shown in Figures 1 to 6, and Figures 9 and 10, the preferred embodiment of the present invention proposes a modular sunlight collection system, including a sunlight collector 1 and a dual-axis platform 2. The sunlight collector 1 is composed of multiple groups of standard sunlight collection modules 9, a sun sensor 5 and a center plate 7. Each set of standard sunlight collection modules 9 is composed of multiple optical lenses 3, multiple fiber optic connectors 4 and two front and rear parallel optical panels 6, the optical panels 6 include a front optical panel 61 and a rear optical panel 62, the multiple optical lenses 3 are distributed and installed on the front optical panel 61, the multiple fiber optic connectors 4 are installed in the fiber holes 621 on the rear optical panel 62, the solar sensor 5 is fixedly installed in the central area of the center plate 7, and its optical axis is in the same direction as the optical lens 3, the dual-axis platform 2 includes a pitch platform 21 and a steering platform 22, the pitch platform 21 and the steering platform 22 are respectively controlled by two sets of independently operated rotating motors, the center plate 7 is a long optical plane plate, which provides optical positioning for the optical lens 3 and the solar sensor 5, and is fixedly installed on the pitch platform 21, the pitch platform 21 is installed on the steering platform 22, and the steering platform 22 is fixedly installed on the base 8.

The center plate 7 is in the shape of a long strip as a whole, and is a plane in optics, so as to play an optical positioning role. The center plate 7 can be a solid flat metal plate; or it can be a hollow rectangular pipe structure, and the upper and lower bottom surfaces are flat structures, which are formed by extrusion of aluminum profiles. There are 8 groups of mechanical connection holes on both sides of the center plate 7, which are used for optical positioning and mechanical fixing of the optical panel 6. In principle, a mechanical connection hole combination includes four mechanical connection holes, and two are distributed on each side of the center plate 7. Each mechanical connection hole combination is used to position and install an optical panel 6. It should be pointed out that the number of combinations of the mechanical connection holes is not limited to 8. The more mechanical connection hole combinations the center positioning plate contains, the more blocks are used to position and install the optical panel 6, and the higher the sunlight collection amount, that is, the output power of the modular sunlight collector 1. The solar sensor 5 is installed near the center position on the center plate 7, and is responsible for sensing the sun's motion trajectory information and providing it to the dual-axis platform 2, so that the modular sunlight collection system always keeps synchronization with the sun and keeps coaxial with the sunlight, and maximizes the collection of sunlight energy. Since the center plate 7 is an optically complete plane, the optical alignment and positioning problems between the multiple optical panels 6 and between the optical panel 6 and the solar sensor 5 are solved, ensuring that the optical axes of all the optical panels 6 and the optical axis of the solar sensor 5 are always in the same direction and parallel to each other. In other words, when the optical axis of the solar sensor 5 is coaxial with the sunlight, all the optical panels 6 and all their optical lenses 3 are also coaxial with the sunlight.

Furthermore, in order to maximize the collection of solar energy and avoid losses during sunlight transmission, as shown in Figures 3, 7, 9 and 10, the optical fiber connector 4 is mainly composed of an optical fiber and an optical fiber sleeve. The light-receiving end of the optical fiber has a mirrored optical fiber end face, which is located at the focal position of the optical lens 3. The optical fiber connector 4 can be a standard SMA905 optical fiber connector 4, or other standard or even non-standard optical fiber connectors 4, or a bare fiber, which are respectively installed and positioned in the optical fiber holes 621 on the rear optical panel 62, so that the optical fiber connectors 4 and the optical lenses 3 correspond one to one, are equal in number, and are maintained on the same optical axis. The axial distance between the optical lens 3 and the exposed end face of the optical fiber is the focal length of the optical lens 3, that is, the light spot formed at the focal length position after the sunlight passes through the optical lens 3 falls on the exposed end face of the optical fiber of the optical fiber connector 4, thereby coupling into the interior of the energy optical fiber. A plurality of optical lenses 3 and a plurality of fiber optic connectors 4 are respectively mounted and fixed on two parallel front optical panels 61 and rear optical panels 62, thereby a complete standard sunlight collection module is completed. The use of optical fibers for the collection and transmission of sunlight can realize an unobstructed optical path and maximize the utilization of the energy collected from the sunlight. In addition, the optical fiber can be bent and wrapped at any angle within its own deformation range, thereby facilitating the installation and layout of the outdoor standard sunlight collection module in the best sunlight exposure position, thereby improving the sunlight acceptance rate and conversion rate.

Furthermore, in order to enable the standard sunlight collection module to be adaptively modularly assembled and disassembled according to customer needs, as shown in Figures 4, 5, 7, 9 and 10, a through hole fixedly connected to the pitch platform 21 is opened in the center position of the center plate 7, a sedimentation trough 611 engaged with the center plate 7 is opened in the middle of the front optical panel 61, and the front optical panel 61 is evenly distributed on both sides of the center plate 7, and the front optical panel 61 and the rear optical panel 62 are fixedly connected by a tapered support waist 63, and the front optical panel 61, the support waist 63 and the rear optical panel 62 form an isosceles trapezoidal structure, and the front optical panel A trapezoidal reinforcing rib 64 is provided at the connection portion between 61 and the center plate 7, a combination plate 65 parallel to the front optical panel 61 is slidably installed in the middle of the front optical panel 61, and positioning holes 651 for installing the optical lens 3 are evenly and equidistantly provided on the combination plate 65. The optical lens 3 can be a spherical convex lens, a quasi-spherical convex lens, or a Fresnel lens. The optical lens 3 is installed in the lens ring 31, and the lens ring 31 is fixedly installed on the inner side of the positioning hole 651 on the combination plate 65. In addition, the number of optical lenses 3 installed can be arranged one by one or installed at intervals, and a filling plate 652 is fixedly installed in the positioning hole 651 where the optical lens 3 is not installed.

After the front optical panel 61 is mechanically connected to the center plate 7 through the sedimentation groove 611 on the panel, it ensures that the front and rear bottom plates of the optical panel 6 are parallel to the center plate 7 in geometric positions, that is, the normal directions are consistent. The optical panel 6 is a trapezoidal sleeve structure as a whole, including two front optical panels 61 and rear optical panels 62 that are parallel to each other up and down, and two supporting waists 63 connected thereto, which are formed by one-time extrusion molding of aluminum profiles and subsequent mechanical processing. The optical panel 6 is divided into three areas, namely the left sunlight collection area, the middle fixed area and the right sunlight collection area. Combination plates 65 are symmetrically installed on the left and right sunlight collection areas, respectively. The thickness and flatness of the combination plates 65 are consistent with those of the front optical panel 61. When the overall installation of the optical panel 6 is completed, the number of optical lenses 3 installed can be quickly adjusted by disassembling and assembling the combination plates 65. It should be pointed out that the lens positioning holes 651 and the optical fiber holes 621 correspond to each other one by one and are optically coaxial. Within the range of the number of optical lenses 3 that can be installed on the combination panel 65, the optical lenses 3 located on the left and right sunlight collection areas can be non-fixed or even asymmetrical. Each set of standard sunlight collection modules is not limited to including 8 optical lenses 3 and 8 optical fiber connectors 4, but can also be 16, 20, or any other number. The present invention does not impose additional restrictions. The filling plate 652 can fill the uninstalled area of the optical lens 3, thereby satisfying the overall sealing effect of the trapezoidal sleeve structure of the optical panel 6, isolating the entry of dust or rain and dew, and improving the service life.

Furthermore, in the actual installation process, it is necessary to avoid the obstruction of buildings or obstacles within the sunlight collection range of the optical lens 3. When selecting the position, it is also necessary to pay attention to its installation height and the change of the center of gravity after loading different numbers of optical panels 6. For this purpose, as shown in Figures 1 to 5, the base 8 is composed of a center frame 81 and support feet 82. The support feet 82 are distributed around the center frame 81. The upper end of the support feet 82 is hingedly installed with a height clamp 821. The height clamp 821 is slidably engaged with the center frame 81. The center frame 81 is evenly provided with through holes 811 for installing and adjusting the height of the height clamp 821. The center plate 7 is a planar structure, which can be a one-stage type or a multi-stage type. When the center plate 7 is a multi-stage type, the end positions of the center plate 7 are all provided with half notches. When the two adjacent center plates 7 are combined and positioned, the end notches of the two adjacent center plates 7 are mutually offset and fitted, and the combined position between the two adjacent center plates 7 is fixed and engaged by a clamping plate 71.

During the actual installation process, multiple supporting feet 82 arranged circumferentially can provide stable support for the central frame 81. By adjusting the installation position between the height clamp 821 and the through hole 811, the supporting feet 82 at different positions can also have their own independent angles and installation height position adjustments, thereby meeting the needs for adapting to rugged terrain conditions and the height position required for installing the optical lens 3. By increasing or decreasing the inclination angle of the supporting feet 82, the center of gravity of the entire modular sunlight collection system can be adaptively raised and lowered to meet its earthquake and wind resistance after installation, thereby improving the environmental adaptability of the sunlight collection system and its dynamic sensing ability after the adjustment of its own installation structure.

Furthermore, after the modular sunlight collection system is installed, its installation position is relatively fixed, but the weather at its installation position will change with the time. In order to prevent dust or broken branches and leaves from falling to the position of the optical lens 3 and causing a reduction in its light transmittance, as shown in Figures 9 to 12, a protective buckle plate 66 is fixedly installed on the upper part of the support waist 63, and both ends of the buckle plate 66 extend to the top of the front optical panel 61, and the combination plate 65 is located on the inner side of the buckle plate 66, and a storage groove 661 is provided on the side of the buckle plate 66 facing the optical lens 3, and an airflow channel 662 is provided on the side of the buckle plate 66 away from the optical lens 3, and airflow grooves 663 are evenly provided between the airflow channel 662 and the storage groove 661.

The entire modular sunlight collection system can be installed with solar panels to provide it with a continuous energy supply. When the control element detects a sudden drop in the light sensitivity of a certain position or a group of optical lenses 3, air flow is ejected from the upper area of the installation position of the optical lens 3 by pneumatic blowing, thereby achieving the removal and discharge of obstructions. In addition, the air flow can be switched to water flow, or water flow and air flow can be carried out simultaneously according to the actual installation environment, thereby realizing a variety of cleaning methods for the surface of the optical lens 3, while improving the light transmittance, achieving self-cleaning, reducing the degree of maintenance participation of personnel, and reducing manpower loss.

Furthermore, the cleaning method using water flow or air flow can isolate most of the obstructions from the obstructions. However, if the upper surface of the optical lens 3 is obstructed by bird excrement, additional appropriate wiping treatment is required to eliminate the interference of the obstruction to the greatest extent. To this end, as shown in Figures 9 to 12, a smooth rod 67 is slidably installed in the storage groove 661. The smooth rod 67 is located above the optical lens 3. The side of the smooth rod 67 facing the optical lens 3 is provided with an inner groove with an obtuse angle. Smooth brushes 671 are staggeredly installed on both sides of the groove of the inner groove, and the smooth brush 671 contacts the optical lens 3 during movement. The end of the smooth rod 67 is fixedly connected to a flexible rope 672, and the other end of the flexible rope 672 is fixedly connected to a tension spring 674 after sliding through the turning groove 673, and the other end of the tension spring 674 is fixedly connected to the buckle plate 66.

In the initial position, the smooth rod 67 is stored in the storage groove 661 and is relatively isolated from the external environment. When the airflow or water flow is ejected from the storage groove 661, the smooth rod 67 is quickly moved outward in the storage groove 661 by the extrusion force. This process drives the smooth brush 671 to move synchronously and gradually increases the deformation of the tension spring 674. The smooth brush 671 can pass through the upper surface of the optical lens 3 during the movement and provide it with a wiping treatment. At the same time, the water flow or airflow follows the smooth brush 671 to achieve wiping. The cleaning part is rinsed and the impact force is used to reduce the residual dirt on the polishing brush 671. At this time, by controlling the spraying mode of water flow or air flow, it is sprayed intermittently, and the deformation recovery ability of the tension spring 674 is used to make the polishing brush 671 wipe back and forth on the upper surface of the optical lens 3, thereby further improving the dirt cleaning ability and the self-cleanliness of the polishing brush 671, providing the optical lens 3 with self-cleaning and maintenance capabilities, while improving the efficiency of sunlight collection, reducing the consumption of human resources and improving the applicable scenarios.

Furthermore, in order to enhance the long-lasting cleaning ability of the polishing brush 671 in complex environments, as shown in Figures 2, 9 and 10, the surface of the front optical panel 61 is evenly installed with scraping teeth 612, and the side of the scraping teeth 612 facing the optical lens 3 is an inclined structure. The scraping teeth 612 and the polishing rod 67 are arranged on both sides of the optical lens 3 opposite to each other, and the polishing brush 671 is in sliding contact with the scraping teeth 612 during movement.

When the polishing rod 67 passes through the optical lens 3 under the push of water flow or air flow, it passes through the scraper tooth 612 area. At this time, the scraper tooth 612 can use its own inclined surface to interweave with the polishing brush 671, and change the resistance size in the round-trip path of the polishing brush 671, so as to peel off the dirt barrier adhering to the polishing brush 671, and cooperate with the blowing of water flow or air flow to realize the discharge and falling of dirt, so that the polishing brush 671 can maintain its own cleanliness after cleaning work and maintain long-lasting cleaning ability.

The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
