Description

Technical Field

[0001] This utility model relates to the field of sunlight guide technology, specifically to a sunlight guide and light-collecting device. Background Technology

[0002] A sunlight-collecting device, also known as a sunlight harvester, collects sunlight through an external collector and directs the light into an indoor space via optical fibers for illumination. During operation, it automatically adjusts to the sun's position, always facing the sun to maximize sunlight exposure. The stronger the external light, the brighter the indoor light; conversely, the weaker the external light, the dimmer the indoor light, thus effectively saving electricity.

[0003] Existing solar light-collecting devices typically consist of a base support, a fully automatic microcomputer control program, a mechanical device for tracking the sun, a light source emitter for use when there is no sun, a filter, a concentrator, a sensor, an acrylic transparent cover, and optical fibers. The acrylic transparent cover serves as a protective shell that shields the concentrator, sensor, filter, and light source emitter without obstructing light transmission. There are no external components on this shell. However, since the device is installed outdoors, it is affected by the external environment. Dust and moisture in the air can adhere to the surface of the transparent cover, affecting its light transmittance. This, in turn, affects the concentrator's ability to collect, compress, and enhance sunlight, as well as its effectiveness in separating ultraviolet rays and blocking infrared rays.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structure, features and effects of this utility model.

[0021] Example: Please refer to Figures 1-3 A sunlight-guiding and collecting device includes a support cylinder 2, a light-collecting body 17 installed on the top of the support cylinder 2, and a transparent cover 1 rotatably connected to the top of the support cylinder 2. The transparent cover 1 is a hemispherical transparent cover 1, which facilitates protection when the light-collecting body 17 is used at any angle. The light-collecting body 17 can adopt common light-collecting mechanisms, including light-concentrating elements, sensors, optical fibers, filters, microcomputer fully automatic control programs, and mechanical devices for tracking the sun. Since this structure is not a major component when the light-collecting device is cleaned, and common existing technologies can be used, it will not be described in detail in the embodiments.

[0022] Because dust will adhere to the transparent cover 1 in the light-collecting device during long-term use, thus affecting the light transmittance of the transparent cover, and consequently affecting the effect of the light-collecting component in collecting, compressing and enhancing sunlight, as well as separating ultraviolet rays and blocking infrared rays; therefore, in this embodiment, the light-collecting device also includes a movable frame 8 slidably connected to the support cylinder 2, a drive component for driving the transparent cover 1 to rotate, a telescopic component for driving the movable frame 8 to move, and an annular water spray cavity 3 fixed to the top of the movable frame 8 and connected to the water supply system. The light-collecting body 17 is located inside the transparent cover 1. The drive component and the telescopic component are both installed on the support cylinder 2. The transparent cover 1 is located inside the annular water spray cavity 3, and the inner side wall of the annular water spray cavity 3 is provided with a number of circumferentially distributed water spray hole groups 12 aligned with the outer wall of the transparent cover 1.

[0023] The water supply system can adopt a common connection between a water pump and a water tank; the drive component and the telescopic component can both adopt common structures for driving rotary and linear motion, which will not be elaborated on in this embodiment; therefore, when cleaning is required, it is only necessary to start the drive component, the telescopic component and the water supply system, so that the transparent cover 1 rotates and the annular water spray chamber 3 moves at the same time. During the movement of the annular water spray chamber 3, a water column with a certain pressure will be sprayed from the water spray hole group 12 onto the surface of the transparent cover 1, thereby cleaning the surface of the transparent cover 1 and eliminating the dust adhering to the transparent cover 1; therefore, this utility model ensures the light transmittance of the transparent cover, effectively ensuring the effect of the light-concentrating component in collecting, compressing and enhancing sunlight, as well as separating ultraviolet rays and blocking infrared rays; when not cleaning, the annular water spray chamber 3 is located at the bottom of the transparent cover 1 to prevent obstruction of sunlight.

[0024] In one embodiment, the top of the support cylinder 2 is provided with a support plate, the light-collecting body 17 is mounted on the support plate, and the driving assembly includes a motor 15 fixed to the support plate, a drive gear 14 fixed to the output end of the motor 15, and an internal gear ring 16 fixed to the bottom of the transparent cover 1 and meshing with the drive gear 14. When the motor 15 is started, the drive gear 14 will rotate, thereby driving the internal gear ring 16 to rotate, and thus realizing the rotation of the transparent cover 1. In addition, a number of limiting gears 18 meshing with the internal gear ring 16 are rotatably connected to the support plate, thereby ensuring the stability of the rotation of the transparent cover 1.

[0025] In one embodiment, the axis of the support cylinder 2 is vertical, and the bottom of the transparent cover 1 is provided with a baffle plate 19. A waterproof cloth 5 is fixed between the baffle plate 19 and the annular spray chamber 3. The bottom of the baffle plate 19 is connected to a drain pipe, which is connected to a drainage system. The drainage system includes a water pump and a wastewater tank for collecting cleaning wastewater and preventing splashing of wastewater during the cleaning process. At this time, the water supply system can use cleaning solution to clean the oil stains on the surface of the transparent cover 1, and then rinse it with clean water, thereby improving the cleaning quality of the transparent cover 1 while effectively preventing the cleaning solution from polluting the surrounding environment. In addition, the bottom of the transparent cover 1 is provided with a vertical ring plate, and the inner toothed ring 16 is provided on the inner wall of the vertical ring plate. When not cleaned, the annular spray chamber 3 is flush with the vertical ring plate and the top of the annular spray chamber 3 does not exceed the top of the vertical ring plate, thereby effectively eliminating the possibility of the annular spray chamber 3 blocking sunlight.

[0026] In one embodiment, the support cylinder 2 is provided with a fixed plate 4, and the telescopic assembly includes a winch 10 fixed to the bottom of the support plate and a wire rope 9 connected to the output end of the winch 10. The end of the wire rope 9 away from the winch 10 is fixed to the bottom end of the moving frame 8, thereby realizing the movement of the moving frame 8 while reducing the overall volume of the device, making the device more compact. The moving frame 8 includes a moving ring plate 7 and a plurality of sliding rods 6 fixed to the top of the moving ring plate 7 and slidably connected to the baffle plate 19. The top of the sliding rods 6 is fixed to the bottom of the annular water spray chamber 3 to achieve stable support for the annular water spray chamber 3.

[0027] In one embodiment, the fixed plate 4 is provided with an annular groove 11, and the drain pipe passes through the annular groove 11; the drive assembly drives the transparent cover 1 to reciprocate within an angle smaller than the central angle corresponding to the annular groove 11, and the central angles corresponding to the two adjacent sets of water spray hole groups 12 are smaller than the central angles corresponding to the annular groove 11, thereby achieving comprehensive cleaning of the outer wall of the transparent cover 1 while greatly reducing the distance between the fixed plate 4 and the baffle plate 19, further improving the compactness of the device structure; at this time, when cleaning is required, the motor 15 starts in both forward and reverse directions alternately, thereby achieving reciprocating rotation of the transparent cover 1 at one angle, thereby achieving comprehensive cleaning of the outer wall of the transparent cover 1.

[0028] In one embodiment, a group of water spray holes 12 includes several water spray holes 13 vertically distributed on an annular water spray chamber 3. The axis of the water spray holes 13 is arranged downwards and outwards. When the annular water spray chamber 3 moves to the top, the bottommost ring of water spray holes 13 points to the center point of the outer wall of the transparent cover 1, thereby further improving the cleaning quality of the outer wall of the transparent cover 1. At the same time, the water sprayed from the other rings of water spray holes 13 will collide, thereby creating a water flow that pours down from top to bottom, effectively rinsing the outer wall of the transparent cover 1. Secondly, the water spray holes 13 arranged downwards and outwards help to prevent the water column from splashing out the waterproof cloth 5 after hitting the surface of the transparent cover 1.

[0029] Working principle: When cleaning is required, simply start the motor 15, winch 10, and water supply system. This causes the transparent cover 1 to rotate back and forth at a certain angle, while simultaneously moving the annular water spray chamber 3. During the movement of the annular water spray chamber 3, a water column with a certain pressure will be sprayed from the water spray hole 13 onto the surface of the transparent cover 1, thereby cleaning the surface of the transparent cover 1 and eliminating the dust adhering to the transparent cover 1. Therefore, this utility model ensures the light transmittance of the transparent cover and effectively ensures the effect of the light-concentrating element in collecting, compressing, and enhancing sunlight, as well as separating ultraviolet rays and blocking infrared rays.
