Description

Technical Field

[0001] The present invention relates to the technical field of natural lighting, and in particular, to a natural lighting system and a lighting method. Background Art

[0002] In order to increase land utilization rate and alleviate the crisis of living space, some sewage treatment plants now adopt fully underground sewage treatment plants. In the underground space, there are problems of relative enclosure and lack of daylighting. Due to the relative enclosure and lack of daylighting, the underground space has characteristics such as relatively dark, confined, cold, and humid, which have a negative impact on the physical and mental health of some workers. Comparing fully underground sewage treatment plants and conventional above-ground sewage treatment plants with the same scale and the same treatment standard, the lighting energy consumption of the underground sewage treatment plant is about 4 to 6 times that of the conventional above-ground sewage treatment plant, and the energy consumption is relatively high. Summary of the Invention

[0003] In order to reduce the lighting energy consumption of underground sewage treatment plants, the present invention provides a natural lighting system and a lighting method.

[0004] The natural lighting system and lighting method provided by the present invention adopt the following technical solutions:

[0005] A natural lighting system includes a controller, a light guiding system, a daylighting system, a positioning system, an optical system, and a lighting system. The daylighting layer is provided with two production areas and an inspection passage. Each of the two production areas is provided with four daylighting sub-areas. The daylighting system is located on the inspection passage. The light guiding system, the positioning system, the optical system, and the lighting system are all located on each daylighting sub-area. The light guiding system, the optical system, and the lighting system in each daylighting sub-area are all distributed in a matrix as a whole. The light guiding system, the positioning system, the optical system, and the lighting system are all communicatively connected to the controller.

[0006] By adopting the above technical solutions, the daylighting of the rectangular array has a relatively high daylighting efficiency, so that the distance between adjacent daylighting sub-areas reaches the optimum, and a better daylighting distribution effect can be obtained. When the light distribution is uneven, the lighting system is used for supplementary lighting to reduce the energy consumption.

[0007] Preferably, the light guiding system includes sixteen light guiding tubes, the daylighting system includes four daylighting windows, the positioning system includes fifteen positioning sensors, the optical system includes sixteen optical sensors, and the lighting system includes thirty-two lighting lamps. Every two light guiding tubes, every two optical sensors, and every four lighting lamps are fixedly installed in the corresponding daylighting zones. Every four lighting lamps are located at the four corners of the matrix, and every two light guiding tubes and every two optical sensors are symmetrically placed on the four sides of the matrix. Among them, four positioning sensors are located at the four corners of the daylighting layer, nine positioning sensors are respectively located on the boundary lines of three daylighting zones, and the other two positioning sensors are respectively located at both ends of the inspection passage.

[0008] By adopting the above technical solution, through daylighting zones, the large daylighting opening is divided into multiple small daylighting openings, which helps to increase sunshading, reduce the over-lighting area, and reduce light pollution.

[0009] Preferably, a light collector and a diffuser are respectively fixedly connected above and below each light guiding tube. The light collector includes a daylighting cover, a heat preservation sealing ring, and a rainproof ring. The heat preservation sealing ring and the rainproof ring are fixedly connected to the bottom of the daylighting cover from top to bottom. A corrugated pipe is fixedly connected to the outer surface of each light guiding tube, and a heat preservation material is fixedly connected to the bottom end of each light guiding tube.

[0010] By adopting the above technical solution, natural light is collected by the light collector at the top, and after being efficiently reflected and transmitted by the light guiding tube, the diffuser evenly guides the natural light to any place where light is needed in the daylighting zone. From dawn to dusk, even on cloudy or rainy days, the light in the daylighting layer of the underground sewage treatment plant is still very sufficient.

[0011] Preferably, the roof at the top of the daylighting layer is a roll roofing or a coated roofing. A waterproof layer is fixedly connected to the roof at the top of the daylighting layer. An additional layer is fixedly connected to a part of the top of the waterproof layer and the top of the corrugated pipe. The height of the additional layer ≥ 300mm, and the length of the additional layer ≥ 250mm; when the roof at the top of the daylighting layer is a planted roofing, a waterproof layer is fixedly connected to the roof at the top of the daylighting layer. An additional layer is fixedly connected to a part of the top of the waterproof layer and the top of the corrugated pipe. The height of the additional layer ≥ 300mm, and the length of the additional layer ≥ 250mm; when the roof at the top of the daylighting layer is a water storage roofing, a waterproof layer is fixedly connected to the roof at the top of the daylighting layer. An additional layer is fixedly connected to a part of the top of the waterproof layer and the top of the corrugated pipe. The height of the additional layer ≥ 300mm, and the length of the additional layer ≥ 250mm.

[0012] By adopting the above technical solutions, the light guide tube has various installation methods, such as lateral installation method, through-layer installation method, straight tube installation method, through-layer turning installation method, flat plate turning installation method, etc., so that the light guide tube can be installed on different roofs, and the underground sewage treatment plant can be built under various grounds, all of which can obtain good natural lighting and reduce the energy consumption of the lighting system.

[0013] Preferably, the distance between the light guide tube and the corrugated pipe is 25mm - 35mm, the thickness of the corrugated pipe is 50mm, the outer surface of the corrugated pipe is covered with a reinforcement project, and the thickness of the reinforcement project is 50mm.

[0014] By adopting the above technical solutions, the corrugated pipe enhances the protection of the light guide tube, and the reinforcement project is used to strengthen the connection between the light guide tube and the corrugated pipe and the ground, prevent the underground buoyancy, and prevent the light guide tube and the corrugated pipe from undergoing large displacements underground.

[0015] A daylighting method includes the following operation steps: A. The daylighting system is closed, there is no manual inspection, and the robot conducts inspections; B. The daylighting system turns on the daytime mode, and manual inspections are carried out; the daylighting system turns on the night mode, and manual inspections are carried out; C. The daylighting system turns on the emergency mode; the daylighting system turns on the maintenance mode.

[0016] By adopting the above technical solutions, it is possible to achieve maintenance without light and without personnel; the inspection equipment is equipped with a lighting lamp and an optical sensor, which can be turned on as needed to reduce energy consumption.

[0017] Preferably, in step B, the specific operation steps for the daylighting system to turn on the daytime mode and conduct manual inspections include that the corresponding optical sensor and positioning sensor transmit data to the controller. When the controller receives the instruction and judges that the natural lighting does not meet the lighting requirements, the controller issues an instruction to turn on the lighting lamp, and the corresponding lighting lamp is turned on; the specific operation steps for the daylighting system to turn on the night mode and conduct manual inspections include that the controller receives the data transmitted by the positioning sensor, judges the position of the inspection personnel, the controller issues an instruction to turn on the lighting lamp, and the corresponding lighting lamp is turned on. After the position of the inspection personnel leaves, the lights in this daylighting zone are turned off after a delay.

[0018] By adopting the above technical solutions, when the inspection personnel approach or move away from the boundary of the daylighting zone, the lights in the daylighting zone can be illuminated in advance and turned off after a delay, and each area operates in sequence, realizing the lighting startup according to the moving path, saving the power consumption of the lights.

[0019] Preferably, in step C, the specific operation steps for the daylighting system to turn on the emergency mode include that when an abnormal alarm occurs in one of the daylighting zones, the lighting in that zone is automatically turned on, and at the same time, the inspection robot arrives at that zone to cooperate in handling the situation; in step C, the specific operation steps for the daylighting system to turn on the maintenance mode include that when there is a need for maintenance of a daylighting zone or a plant-wide maintenance, each zone or the whole plant operates according to the conventional plant lighting mode.

[0020] By adopting the above technical solution, when an accident alarm occurs or maintenance is required in the buried sewage treatment plant, the controller can directly indicate the location through the lighting system, and natural light can continue to be used in other daylighting zones. For maintenance workers and inspection workers, the location of the alarm or the maintenance location is clearly visible.

[0021] In summary, the present invention has the following beneficial technical effects:

[0022] 1. In the present invention, the light guiding system, the optical system, and the lighting system in each daylighting zone are all distributed in a matrix as a whole, which is beneficial to reducing the problem of excessive daylighting caused by large openings, and the effective daylighting area is the largest. By making full use of the superposition effect between combinations, the effective daylighting area is increased. When the light distribution is uneven, supplementary lighting is carried out through the lighting system, which is beneficial to reducing energy consumption.

[0023] 2. The present invention is provided with light pipes. The roof at the top of the daylighting layer is a rolled material, coated film roof, planted roof, or water storage roof. There are various installation methods for the light pipes, such as lateral installation method, cross-layer installation method, straight pipe installation method, cross-layer turning installation method, and flat plate turning installation method, etc., so that the light pipes can be installed on different roofs. Water can be stored and heat can be insulated on the roof top, or greenery can be planted to prevent the heat brought by high-temperature weather from entering the ground and save other heat insulation energy consumption.

[0033] The following further elaborates on the present invention in conjunction with the attached Figures 1 - 5 drawings.

[0034] An embodiment of the present invention discloses a natural lighting system.

[0035] Refer to Figure 1, including a controller, a light guide system, a daylighting system, a positioning system, an optical system, and a lighting system. The daylighting layer is provided with two production areas and an inspection passage. The daylighting layer is separated into two production areas and an inspection passage by two transparent partition walls 15. The inspection passage is located between the two production areas. Stairwells 16 are provided at both ends of one of the production areas, and both stairwells 16 are connected to the inspection passage. Four daylighting zones are provided in both production areas. The two production areas are respectively Production Area 1 and Production Area 2. The four daylighting zones are respectively Daylighting Zone 1, Daylighting Zone 2, Daylighting Zone 3, and Daylighting Zone 4. The daylighting system is located on the inspection passage. The light guide system, the positioning system, the optical system, and the lighting system are all located on each daylighting zone. The light guide system, the optical system, and the lighting system within each daylighting zone are all arranged in a matrix as a whole. The matrices are arranged relatively to reduce the problem of excessive daylighting caused by large openings, and the effective daylighting area is the largest, making full use of the superposition effect of the combination rooms to increase the effective daylighting area. The light guide system, the positioning system, the optical system, and the lighting system are all communicatively connected to the controller.

[0036] Refer to Figure 1 , the light guide system includes sixteen light guide tubes 1, the daylighting system includes four daylighting windows 6, the four daylighting windows 6 are arranged in a linear array on the inspection passage, the positioning system includes fifteen positioning sensors 7, the optical system includes sixteen optical sensors 8, and the lighting system includes thirty-two lighting lamps 9. Every two light guide tubes 1, every two optical sensors 8, and every four lighting lamps 9 are fixedly installed in the corresponding daylighting zone. Every four lighting lamps 9 are located at the four corners of the matrix. Every two light guide tubes 1 and every two optical sensors 8 are symmetrically placed on the four sides of the matrix. Four of the positioning sensors 7 are located at the four corners of the daylighting layer. Nine of the positioning sensors 7 are respectively located on the boundary lines 10 of three daylighting zones. The other two positioning sensors 7 are respectively located at both ends of the inspection passage. The controller determines to turn on or off the corresponding lighting lamps 9 by receiving the data of the positioning sensors 7 and the optical sensors 8.

[0037] Refer to Figure 1 , Figure 2 , a light collector and a diffuser are respectively fixedly connected above and below each light guide tube 1. The light collector includes a daylighting cover 2, a heat preservation sealing ring 3, and a rainproof collar 4. The airtightness of the light guide tube 1 is enhanced through the heat preservation sealing ring 3 and the rainproof collar 4. At the same time, in winter, the heat loss of the underground sewage treatment plant is reduced, and in summer, the heat on the ground is prevented from entering. The heat preservation sealing ring 3 and the rainproof collar 4 are fixedly connected to the bottom of the daylighting cover 2 from top to bottom. A corrugated pipe 11 is fixedly connected to the outer surface of each light guide tube 1. The corrugated pipe 11 uses a finished high-density polyethylene special corrugated pipe 11. A heat preservation material 5 is fixedly connected to the bottom end of each light guide tube 1.

[0038] Refer to Figure 2 , Figure 3, Figure 4 , the roof at the top of the daylighting layer is a coiled material, film-coated roof, planted roof, or water storage roof. A waterproof layer 12 is fixedly connected to the roof at the top of the daylighting layer. The waterproof layer 12 prevents rainwater during the flood season from entering the light guide pipe 1. At the top of a part of the waterproof layer 12 and the top of the corrugated pipe 11, an additional layer 13 is fixedly connected. The additional layer 13 is bonded at the connection between the corrugated pipe 11 and the roof to enhance the waterproofness of the connection and prevent rainwater from seeping into the underground sewage treatment plant. The height of the additional layer 13 ≥ 300 mm, the length of the additional layer 13 ≥ 250 mm, and the reserved hole of the corrugated pipe 11 can be 600 mm. Through the height difference of the additional layer 13, water can be stored and insulated on the roof, or greenery can be planted to prevent heat from high-temperature weather from entering the ground.

[0039] Refer to Figure 5 , the distance between the light guide pipe 1 and the corrugated pipe 11 is 25 mm - 35 mm. The light guide pipe 1 can adopt the STGC530 model with an inner diameter of 530 mm, and the corrugated pipe 11 can adopt an inner diameter of 600 mm. Thus, the distance between the inner diameter of the corrugated pipe 11 and the light guide pipe is 35 mm, the thickness of the corrugated pipe 11 is 50 mm, and the outer surface of the corrugated pipe 11 is covered with a reinforcement project 14. The reinforcement project 14 is a flanged reinforcement as seen in the single project and is located between the corrugated pipe 11 and the waterproof layer 12. The thickness of the reinforcement project 14 is 50 mm.

[0040] This embodiment also discloses a daylighting method.

[0041] Refer to Figure 1 , which includes the following operation steps: A. When the daylighting system is closed and there is no manual inspection, during robot inspection, the daylighting system includes a full-automatic mode and a semi-automatic mode; when there is no manual inspection, the full-automatic mode of the daylighting system can be turned on: the whole plant adopts unmanned operation and maintenance and runs automatically. At this time, all daylighting lights are turned off, and various robots rely on designated routes, radar, laser detection, etc. to achieve operation and maintenance without light and without people. There is no daylighting energy consumption in the whole plant, and the energy consumption is the lowest; semi-automatic mode: the whole plant adopts unmanned operation and maintenance, and there is no need for personnel to enter the underground space. However, some inspection operations require remote control or monitoring by personnel. At this time, all daylighting lights are turned off, and the robots that need to be controlled or monitored use their own lighting to achieve unmanned remote operation and maintenance. There is no daylighting energy consumption in the whole plant, and the energy consumption is extremely low.

[0042] The robot is equipped with an optical sensor 8 itself. When the daylighting during the day meets the requirements, there is no need to turn on its own lighting equipment, which is more energy-saving.

[0043] B. When the daylighting system is turned on to the daytime mode and there is a manual inspection, after entering the daylighting layer, the positioning system determines the position of the inspection personnel, retrieves the light sensor data here, and determines whether it meets the requirements. When it meets the requirements, natural daylighting can be used; when it does not meet the requirements, artificial lighting is turned on;

[0044] When the daylighting system turns on the night mode and manual inspections are carried out, after personnel enter the underground space, the positioning system determines the personnel's location, turns on the lights in this daylighting zone in advance, and delays turning off the lights in this daylighting zone after leaving this area;

[0045] C. The daylighting system turns on the emergency mode; the daylighting system turns on the maintenance mode.

[0046] Refer to Figure 1 , in step B, when the daylighting system turns on the day mode and manual inspections are carried out, the specific operation steps include that the corresponding optical sensor 8 and positioning sensor 7 transmit data to the controller. The controller receives the instruction and judges the natural daylighting. When the daylighting requirement is not met, the controller issues an instruction to turn on the lighting lamp 9, and the corresponding lighting lamp 9 is turned on. If the lighting lamp 9 adopts an illuminance adjustable mode, it automatically adjusts according to the light sense data to calculate the required supplementary illuminance;

[0047] Refer to Figure 1 , in step B, when the daylighting system turns on the night mode and manual inspections are carried out, the specific operation steps include that the controller receives the data transmitted by the positioning sensor 7, judges the location of the inspection personnel, the controller issues an instruction to turn on the lighting lamp 9, and the corresponding lighting lamp 9 is turned on. After the inspection personnel leave the position, the lights in this daylighting zone are turned off after a delay, that is, when the inspection personnel enter the inspection passage from one side of the staircase 16, the lighting in daylighting zone one is automatically turned on in advance; when the inspection personnel are 10 m away from the boundary 10 between daylighting zone one and daylighting zone two, the lighting lamp 9 in daylighting zone two is automatically turned on; when the inspection personnel enter daylighting zone two and are 10 m away from the boundary line, the lighting lamp 9 in daylighting zone one is automatically turned off, and then each area runs in sequence to realize starting the lighting according to the moving path.

[0048] Refer to Figure 1 , in step C, the specific operation steps for the daylighting system to turn on the emergency mode include that when an abnormal alarm occurs in one of the daylighting zones, the lighting in this area is automatically turned on, and at the same time, the inspection robot arrives at this area to cooperate in handling; in step C, the specific operation steps for the daylighting system to turn on the maintenance mode include that when there are requirements such as maintenance of the daylighting zone or maintenance of the whole plant, each area or the whole plant operates according to the conventional plant lighting mode, and the lighting lamp 9 is turned on and off in different situations, saving power consumption and at the same time enhancing the safety of maintenance.

[0049] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
