Description
Technical Field
[0001] This utility model relates to the field of building technology, and in particular to a skylight roof building structure. Background Technology
[0002] In modern architectural design, skylights are widely used because they can introduce natural light and enhance the sense of openness and comfort of interior spaces. However, traditional skylights face many problems in actual use.
[0003] On the one hand, the means of controlling daylighting are relatively simple. Most skylights can only provide a fixed area and intensity of light, making it difficult to adjust flexibly according to different seasons, times, and indoor usage needs. During periods of strong sunlight, excessive direct sunlight can cause a sharp rise in indoor temperature, increasing the cooling load on air conditioning and resulting in energy waste. On the other hand, in some scenarios where soft lighting or sun protection is required, it is not effective in filtering harmful rays such as ultraviolet rays, which can affect the health of people indoors and the lifespan of indoor decorations and furniture.
[0004] On the other hand, the cleaning and maintenance of skylights is quite difficult. Over time, dust and dirt easily accumulate on the surface of skylights. These pollutants will significantly reduce the light transmittance and affect the lighting effect. Traditional cleaning methods often rely on manual high-altitude operations, which are not only inefficient but also pose high safety risks. At the same time, the cleaning process consumes a lot of water resources, increasing the building's operating costs and is not in line with the development trend of environmental protection and energy conservation.
[0005] Therefore, how to provide a skylight roof structure with lighting adjustment and cleaning and maintenance functions is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] One objective of this invention is to propose a skylight roof structure that integrates the advantages of flexible adjustment of lighting and shading, automatic cleaning of light-transmitting panels, and efficient collection and utilization of rainwater. It can not only accurately adapt to diverse lighting needs and maintain good lighting effects, but also make full use of natural resources and reduce energy consumption and operating costs, thus creating an intelligent, comfortable, environmentally friendly and energy-saving skylight roof solution for buildings.
[0007] A skylight roof structure according to an embodiment of the present utility model includes a mounting base, an arched frame, a roller shutter box, and a rainwater collection box;
[0008] An arched frame is fixedly welded to the top of the mounting base, and roller shutter boxes are symmetrically fixedly installed on both sides of the bottom of the mounting base. A black light-blocking film and a light-transmitting sun-protective film are respectively wound inside the two sets of roller shutter boxes, and the protruding ends of the black light-blocking film and the light-transmitting sun-protective film are fixedly connected by glue.
[0009] The arched frame has movable pipes symmetrically installed on both sides via a pivot axis. The tops of the two sets of movable pipes are horizontally fixed with branch pipes, and the two ends of the branch pipes are connected to the two sets of movable pipes. Rainwater collectors are fixedly installed on the top of the mounting base and on the front and rear sides of the arched frame, respectively. A rainwater collection box is fixedly installed on one side of the bottom of the mounting base and on the outer wall of the roller shutter box. A water pump is installed inside the rainwater collection box, and an output pipe is installed at the top output end of the water pump. The other end of the output pipe is connected to the movable pipe.
[0010] Furthermore, a rubber scraper is fixedly installed horizontally at the center of the bottom of the branch pipe, and several sets of nozzles are installed at the bottom of the branch pipe on both sides of the rubber scraper, with the nozzles evenly distributed at the bottom of the branch pipe.
[0011] Furthermore, a roller shutter motor is embedded inside one side of the roller shutter box, and the output end of the roller shutter motor is connected to the winding roller inside the roller shutter box.
[0012] Furthermore, servo motors are symmetrically installed at the center of both sides of the inner wall of the arched frame, and the output shaft of the servo motor is connected to the rotating shaft of the arched frame via a movable tube.
[0013] Furthermore, both sets of rainwater collectors have an outward-sloping top design, and a filter panel is fixedly installed on the top of the rainwater collector.
[0014] Furthermore, a rotary joint is provided below the movable tube, and the output tube is connected to the movable tube through the rotary joint, and the rotating shaft used by the arched frame connecting the rotary joint and the movable tube is on the same axis.
[0015] Furthermore, a T-shaped pipe is fixedly installed on the same side of both sets of rainwater collectors, and the other end of the T-shaped pipe is connected to the rainwater collection box.
[0016] Furthermore, a light-transmitting plate with the same curvature as the arched frame is fixedly installed on the surface of the arched frame, and the bottom of the rubber scraper is in close contact with the surface of the light-transmitting plate.
[0017] Furthermore, guide rails are symmetrically installed at the bottom of the mounting base and on both sides of the two sets of roller shutter boxes, and the black light-blocking film and the light-transmitting sun-protecting film are movably installed in the guide rails on both sides.
[0018] The beneficial effects of this utility model are:
[0019] This invention features a black shading film and a light-transmitting sun-protective film. The roll-up motor allows for convenient control of both films' unfolding and retraction. In the scorching summer, the black shading film effectively blocks a large amount of solar radiation, lowering indoor temperature and reducing energy consumption for air conditioning and other cooling equipment, creating a cool and comfortable indoor environment. In spring and autumn, or in scenarios requiring softer lighting and sun protection, the light-transmitting sun-protective film allows some light to enter while filtering out most harmful ultraviolet rays, protecting people and items from UV damage and extending the lifespan of interior decorations and furniture. This significantly improves the applicability and flexibility of the skylight roof under different lighting conditions and usage requirements.
[0020] This invention uses a servo motor to drive the movable pipe and branch pipes to move along the light-transmitting panel. A water pump delivers rainwater from the rainwater collection tank to the nozzles, spraying and rinsing the light-transmitting panel thoroughly and evenly. This automated cleaning method eliminates the need for manual climbing of the roof for cleaning, improving cleaning efficiency and reducing the danger of cleaning operations. Furthermore, the rubber scraper closely adheres to the surface of the light-transmitting panel, promptly removing sewage and residual dirt after the nozzles rinse, ensuring a high degree of cleanliness and maintaining good light transmission performance. This prevents the accumulation of dirt from reducing the light transmission effect and affecting the indoor natural lighting environment, providing continuous and stable bright lighting indoors, reducing the use of artificial lighting, and further reducing energy consumption.
[0021] This invention effectively collects rainwater through a rainwater collector. Its outward-sloping top design prevents debris from accumulating and clogging the system. The filter panel removes leaves, impurities, and other contaminants from the rainwater, ensuring relatively clean collected rainwater. The collected rainwater is stored in a rainwater collection tank and can be used for cleaning transparent panels. This fully utilizes natural resources, reduces dependence on external water resources such as municipal water supply, lowers water consumption, and aligns with the principles of environmental protection and energy conservation.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention. Example
[0029] refer to Figure 1-3 A skylight roof structure includes a mounting base 1, an arched frame 2, a roller shutter box 12, and a rainwater collection box 11;
[0030] An arched frame 2 is fixedly welded to the top of the mounting base 1. Roller blind boxes 12 are symmetrically fixedly installed on both sides of the bottom of the mounting base 1. A black light-blocking film 15 and a light-transmitting sun-protective film 16 are respectively rolled inside the two sets of roller blind boxes 12, and the protruding ends of the black light-blocking film 15 and the light-transmitting sun-protective film 16 are fixedly connected by glue.
[0031] Among them, a roller shutter motor 13 is embedded in one side of the roller shutter box 12, and the output end of the roller shutter motor 13 is connected to the winding roller inside the roller shutter box 12.
[0032] Secondly, guide rails 14 are symmetrically installed at the bottom of the mounting base 1 and on both sides of the two sets of roller blind boxes 12. The black light-blocking film 15 and the light-transmitting sun-protective film 16 are movably installed in the guide rails 14 on both sides. The guide rails 14 can ensure that the black light-blocking film 15 and the light-transmitting sun-protective film 16 can remain stable when they are retracted and extended, and avoid light leakage caused by gaps on both sides.
[0033] In this embodiment, when shading is needed, the roller shutter motor 13 is started, which drives the winding roller to rotate and causes the black light-blocking film 15 to unfold, thereby blocking sunlight. When both light and sun protection are needed, the roller shutter motor 13 can be controlled to unfold the light-transmitting sun-protective film 16, and the light-transmitting and sun-shading states can be flexibly adjusted according to different light requirements. Example
[0034] refer to Figure 1-4The arched frame 2 has movable tubes 4 symmetrically installed on both sides via a pivot axis. The top of the two sets of movable tubes 4 is horizontally fixed with branch tubes 5, and the two ends of the branch tubes 5 are connected to the two sets of movable tubes 4. Servo motors 8 are symmetrically installed at the center of both sides of the inner wall of the arched frame 2. The output shaft of the servo motor 8 is connected to the pivot shaft of the arched frame 2 via the movable tubes 4.
[0035] Among them, a rubber scraper 17 is fixedly installed horizontally in the center of the bottom of the branch pipe 5, and several sets of nozzles 18 are installed at the bottom of the branch pipe 5 and on both sides of the rubber scraper 17, and the nozzles 18 are evenly distributed at the bottom of the branch pipe 5.
[0036] Secondly, a light-transmitting plate 3 with the same curvature as the arched frame 2 is fixedly installed on the surface of the arched frame 2, and the bottom of the rubber scraper 17 is in close contact with the surface of the light-transmitting plate 3.
[0037] It should be noted that a rotary joint is provided below the movable tube 4, and the output tube 10 is connected to the movable tube 4 through the rotary joint. The rotating shaft used by the rotary joint and the arched frame 2 connecting the movable tube 4 is on the same axis.
[0038] In this embodiment, when it is necessary to clean the light-transmitting plate 3, the servo motor 8 is started, which drives the movable pipe 4 to rotate, thereby causing the branch pipe 5 to move along the light-transmitting plate 3. At the same time, the water pump in the rainwater collection tank 11 is started, which delivers rainwater through the output pipe 10 to the movable pipe 4 and sprays it out from the nozzle 18 to rinse the light-transmitting plate 3. The rubber scraper 17 scrapes off the dirt and water stains on the surface of the light-transmitting plate 3 during the movement of the branch pipe 5, ensuring the cleanliness of the light-transmitting plate 3 and ensuring the lighting effect. Example
[0039] refer to Figure 1-2 Rainwater collectors 6 are fixedly installed on the top of the mounting base 1 and on the front and rear sides of the arched frame 2 respectively. Rainwater collection box 11 is fixedly installed on one side of the bottom of the mounting base 1 and on the outer wall of the roller shutter box 12. A water pump is installed inside the rainwater collection box 11, and an output pipe 10 is installed at the top output end of the water pump. The other end of the output pipe 10 is connected to the movable pipe 4.
[0040] Both rainwater collectors 6 have an outward-sloping top design, and a filter panel 7 is fixedly installed on the top of the rainwater collectors 6. The sloping design can effectively prevent foreign objects from accumulating on the top of the rainwater collectors 6 and causing blockage when collecting rainwater.
[0041] Secondly, two sets of rainwater collectors 6 are fixedly installed with a three-way pipe 9 on the same side, and the other end of the three-way pipe 9 is connected to the rainwater collection box 11.
[0042] In this embodiment, when it rains, rainwater flows in along the inclined surface at the top of the rainwater collector 6, and after being filtered out of impurities by the filter panel 7, it flows into the rainwater collection box 11 through the three-way pipe 9 for storage, so that it can be used for cleaning the light-transmitting plate 3 and other purposes, thereby realizing the collection and reuse of rainwater and improving resource utilization.
[0043] Working principle: During daily use, when the sunlight is strong and the room does not require excessive sunlight, the roller blind motor 13 is started. Its output drives the roller roller inside the roller blind box 12 to rotate, causing the black light-blocking film 15 to slowly extend and unfold from the roller blind box 12. It covers a large area above the light-transmitting panel 3 of the arched frame 2, effectively blocking sunlight from entering the room and providing sun protection and heat insulation. When the room needs lighting and a certain degree of sun protection, the roller blind motor 13 is reversed, causing the light-transmitting sun-protective film 16 to unfold. This allows some light to pass through while reducing ultraviolet rays. To prevent harmful light from entering and create a suitable lighting environment indoors, when dust or stains accumulate on the surface of the light-transmitting panel 3, affecting the lighting effect, the servo motor 8 is activated. The output shaft of the servo motor 8 drives the rotating shaft of the movable pipe 4 connected to it, which is connected to the arched frame 2, to rotate. This causes the movable pipe 4 and the branch pipe 5 fixed at its top to move slowly along the arc of the light-transmitting panel 3. At the same time, the water pump inside the rainwater collection tank 11 starts working, transporting the rainwater stored in it to the movable pipe 4 through the output pipe 10. Since the movable pipe 4 and the branch pipe 5 are interconnected, the rainwater flows out from the branch pipe under pressure. The nozzles 18, evenly distributed on both sides of the bottom of the branch pipe 5, spray mist evenly onto the surface of the light-transmitting plate 3, washing away dirt. Meanwhile, the rubber scraper 17, horizontally fixed in the center of the bottom of the branch pipe 5, closely adheres to the surface of the light-transmitting plate 3 as the branch pipe 5 moves, scraping away the wastewater and residual dirt washed off by the nozzles 18, ensuring the surface of the light-transmitting plate 3 is clean and guaranteeing good lighting performance. Furthermore, because the rotating joint below the movable pipe 4 and the axis of rotation of the arched frame 2 connecting the movable pipe 4 are on the same axis, the output pipe 10 can stably supply light to the movable pipe 4 during its rotation. The water will not be twisted or have poor connection due to rotation. During rainy weather, rainwater naturally falls on the rainwater collectors 6 located on the top of the mounting base 1 and on the front and rear sides of the arched frame 2. The filter panel 7 fixedly installed on the top of the collectors can effectively intercept larger particles such as leaves and debris, thus initially purifying the rainwater. After initial filtration, the rainwater flows into the rainwater collection box 11 for storage through the three-way pipe 9 fixedly installed on the same side of the two sets of rainwater collectors 6. The stored rainwater can be used as a water source when cleaning the light-transmitting plate 3, reducing dependence on external water resources and improving the utilization rate of water resources.
[0044] It is understood that the servo motor, roller shutter motor, and water pump in this invention can be driven by an external power supply. The servo motor, roller shutter motor, and water pump can be programmed and controlled by a main control system, and their control principles are achievable using existing control technologies. The models of the servo motor, roller shutter motor, and water pump are not limited to a single type and can be any type currently available on the market suitable for this invention.
[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
