Description

Technical Field

[0001] This invention relates to the field of building structure technology, specifically to a skylight structure for the roof of a stadium. Background Technology

[0002] In modern architecture, skylights have become a common lighting measure to improve indoor lighting. Skylights can bring ample natural light into the interior, making it brighter and fresher, thereby improving people's comfort in their work and life.

[0003] Common skylights are usually made by opening a skylight in the roof and sealing the skylight with a window made of glass or other transparent material. On rainy days, rainwater will accumulate on the skylight and it will be difficult to drain. On sunny days, sunlight will pass through the water and affect the indoor lighting.

[0004] Moreover, this type of simple structure with skylights is suitable for small buildings, such as classrooms, but not for large venues like gymnasiums.

[0005] To overcome the difficulty of lighting the stadium roof, as per the instruction manual... Figure 1 As shown in the upper middle side view, the structure of the gymnasium in this application is designed as follows: including the gymnasium body, roof, skylight, and overlay layer. The skylight is covered by the overlay layer, and sunlight enters the gymnasium body through the side window of the overlay layer.

[0006] The large-area skylights in this structure are not sealed off by skylights, but are designed as covered atrium structures to overcome the shortcomings of skylights.

[0007] However, the added layer is still somewhat inadequate, as shown in the attached diagram in the instruction manual. Figure 1 As shown in the lower middle side diagram, without using transparent materials for the skylight, the introduction of sunlight through the cover layer is affected by the angle of sunlight. When the angle of sunlight is blocked by the cover layer, the sunlight cannot shine directly in, resulting in poor lighting effect.

[0008] When sunlight can shine directly in, due to the structural limitations of the overlay, sunlight entering from one side window of the overlay will illuminate a part of the stadium floor and then reflect onto the stadium roof, as shown in the figure, resulting in uneven lighting on both sides of the stadium, with one side of the sunlight path being bright and the other side relatively dark.

[0009] Therefore, a structural design is needed to achieve a relatively balanced indoor lighting in the gymnasium. Summary of the Invention

[0010] To address the shortcomings of the aforementioned technologies, this invention provides a roof lighting structure for a gymnasium.

[0011] The technical solution of the present invention: a roof lighting structure for a gymnasium, the gymnasium including a building body, a roof, a lighting opening, and a cover layer, the cover layer covering the lighting opening and having windows on the sides, and also including an outer refractive device and an inner refractive device, the inner refractive device including an annular refractive plate adapted to the contour of the lighting opening, several light sensors, several sets of electric winches, and a PLC controller, the several sets of electric winches being fixedly connected to the cover layer and distributed along the contour of the annular refractive plate, the ropes of the several sets of electric winches being fixedly connected to each part of the annular refractive plate, suspending the annular refractive plate at the lighting opening, the annular refractive plate having a light-transmitting opening in the center; The plurality of light sensors are distributed on the inner side of the light-collecting opening to monitor the changes in the brightness of sunlight transmitted through each window on the side of the cover layer. The PLC controller controls the linkage between each electric winch to wind up or release the rope according to the signals of each light sensor, driving the annular refracting plate to tilt, so that the end of the annular refracting plate on the side with lower brightness is lowered, and the end is lowered to extend beyond the light-collecting opening. The external refracting device includes several refracting plates disposed on the outside of the cover layer, which refract sunlight outside the window's daylight hours into the cover layer.

[0012] The above technical solution is adopted, as shown in the appendix to the instruction manual. Figure 2 , 3 As shown, after the internal refractive device is installed in the structure of the gymnasium in this application, the comparative instruction manual is attached. Figure 1 As can be seen, with changes in the angle of sunlight, the amount of light inside the stadium varies depending on the different side windows of the conventional skylight. By using several light sensors installed on the inner side of the skylight, the differences in light intensity signals at various locations are used to determine changes in the angle and intensity of sunlight. This, in turn, drives each electric winch to start and stop, raising and lowering ropes of different lengths. This causes the annular light-reflecting plate to tilt, lowering the end of the annular light-reflecting plate on the side with lower relative brightness until it extends beyond the skylight.

[0013] In this setup, some sunlight still shines into the stadium through the light-transmitting opening of the annular light-reflecting plate, while some sunlight shines onto the annular light-reflecting plate itself. Due to the tilt of the annular light-reflecting plate, especially its lowered end that extends beyond the light-transmitting opening, a portion of the sunlight is refracted towards the darker areas, achieving a relatively balanced adjustment of the sunlight brightness inside the stadium.

[0014] A further feature of the present invention is that the external refracting device covers the cover layer and includes a support frame, and several groups of first refracting plates, second refracting plates, adjusting rods, driving plates, driving motors, and driving gears arranged on each outer surface of the cover layer. Several light-transmitting holes are provided on the first refracting plates and the second refracting plates. Both the first and second refracting plates include a first hinge end and a second hinge end. The first hinge ends of the first and second refracting plates are provided with a first hinge shaft for mutual hinge connection. One end of the adjusting rod is provided with a connecting hole sleeved on the first hinge shaft. The support frame is provided with a sliding hole for the adjusting rod to pass through and slide axially. The support frame is provided with a cantilever at the second hinge end position of the first and second refracting plates respectively. The cantilever is provided with a sliding groove perpendicular to the axis of the adjusting rod. The second hinge end of the first and second refracting plates is provided with a second hinge shaft. The second hinge shaft of the first and second refracting plates is inserted into the sliding groove of the adjacent cantilever for sliding engagement. The end of the adjusting rod that passes through the sliding hole is provided with a pin in the radial direction. The support frame is provided with a guide groove perpendicular to the axis of the adjusting rod. The driving plate is inserted into the guide groove for sliding engagement. The driving plate is provided with several driving grooves corresponding to the pin positions of each adjusting rod. The pin extends into the corresponding driving groove for sliding engagement. The drive plate has a rack on one side. The output shaft of the drive motor is coaxially linked with the drive gear. The drive gear meshes with the rack. Each drive motor is connected to the PLC controller signal and controls the start, stop and forward / reverse rotation according to the signals of each light sensor.

[0015] With the above technical solution, when the angle of sunlight passes the window and reaches the top surface of the overlay, sunlight cannot be directly projected into the side window, resulting in a decrease in the lighting effect of the stadium.

[0016] Therefore, by using the external refracting device, as shown in the instruction manual... Figure 4-7 As shown, the PLC controller controls the start, stop, forward and reverse rotation of each drive motor, which in turn drives the drive plate to move via a rack. When the drive plate slides along the guide groove of the support frame, the drive slant groove on the drive plate drives the pin to move, which in turn pushes and pulls the first hinge shaft by the adjusting rod. With the support and sliding of the cantilever slide groove and the second hinge shaft, the angle between the first and second refracting plates is ultimately controlled, as shown in the attached instruction manual. Figure 8 As shown, the angle between the first and second refracting plates is adjusted according to the angle of sunlight, so that sunlight is guided and refracted into the window of the overlay layer, which makes up for the problem of insufficient brightness in the stadium after the overlay layer blocks direct sunlight.

[0017] A further feature of the present invention is that both the first and second refracting plates include a refractive surface facing the side of the cover layer and a dark surface facing outwards.

[0018] A further feature of the present invention is that the annular light-refracting plate includes a refractive surface facing the roof and a dark surface facing the bottom plate, and a lighting component is provided on the dark surface of the annular light-refracting plate facing the ground.

[0019] By adopting the above technical solution, a dark side is set to avoid unnecessary refraction.

[0020] The beneficial effects of the present invention are as follows: By setting up the skylight structure on the top of the stadium, the insufficient brightness and uneven distribution of light inside the stadium caused by the addition of a cover layer to block direct sunlight can be compensated when a large area of ​​the building's skylight openings is not covered with a transparent material.

Detailed Implementation

[0022] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. It should be noted that these embodiments are provided... The embodiments described herein are intended to enable a more thorough understanding of this disclosure and to fully convey the scope of this disclosure to those skilled in the art. This disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0023] like Figure 1-8 As shown, a roof lighting structure for a gymnasium includes a gymnasium body 11, a roof 12, a lighting opening 13, and a cover layer 14. The cover layer 14 covers the lighting opening 13 and has windows 15 on its sides. It also includes an outer refractive device 2 and an inner refractive device. The inner refractive device includes an annular refractive plate 31 adapted to the contour of the lighting opening 13, several light sensors 32, several sets of electric winches 33, and a PLC controller. The several sets of electric winches 33 are fixedly connected to the cover layer 14 and are distributed along the contour of the annular refractive plate 31. The ropes 331 of the several sets of electric winches 33 are fixedly connected to each part of the annular refractive plate 31, suspending the annular refractive plate 31 at the lighting opening 13. The annular refractive plate 31 has a light-transmitting opening in the center. The plurality of light sensors 32 are distributed at various locations on the inner side of the light-collecting opening 13 to monitor the changes in sunlight brightness transmitted through each window 15 on the side of the cover layer 14. The PLC controller controls the linkage between each electric winch 33 to wind up or release the rope 331 according to the signals of each light sensor 32, driving the annular refracting plate 31 to tilt, so that the end of the annular refracting plate 31 on the side with lower brightness is lowered, and this end is lowered to extend beyond the light-collecting opening 13. The external refracting device 2 includes several refracting plates disposed on the outside of the cover layer 14, which refract sunlight outside the daytime of the window 15 into the cover layer 14.

[0024] As per the instruction manual Figure 2 , 3 As shown, after the internal refractive device is installed in the structure of the gymnasium in this application, the comparative instruction manual is attached. Figure 1 As can be seen, with the change of the angle of sunlight, the sunlight will cause changes in the illuminated areas inside the stadium due to the different side windows 15 of the conventional overlay layer 14. By using several light sensors 32 installed on the inner side of the light-transmitting opening 13, the changes in the angle and intensity of sunlight are determined by the differences in the light brightness signals at each location. The corresponding electric winches 33 are started and stopped to raise and lower ropes 331 of different lengths, driving the annular light-reflecting plate 31 to tilt, so that the end of the annular light-reflecting plate 31 on the side with lower brightness is lowered, and this end is lowered to extend beyond the light-transmitting opening 13.

[0025] In this setup, some sunlight passes through the light-transmitting opening of the annular refracting plate 31 and is still projected into the gymnasium, while some sunlight is projected onto the annular refracting plate 31. Due to the tilt of the annular refracting plate 31, especially its end extending beyond the light-transmitting opening 13, a portion of the sunlight is refracted towards the darker areas, achieving a relatively balanced adjustment of the sunlight brightness inside the gymnasium.

[0026] The external refracting device 2 covers the cover layer 14 and includes a support frame 21, and several sets of first refracting plates 22, second refracting plates 23, adjusting rods 24, driving plates 25, driving motors 26, and driving gears 27 arranged on each outer surface of the cover layer 14. Several light-transmitting holes 221 are provided on the first refracting plates 22 and the second refracting plates 23. The first refracting plate 22 and the second refracting plate 23 both include a first hinge end 222 and a second hinge end 223. The first hinge end 222 of the first refracting plate 22 and the second refracting plate 23 are provided with a first hinge shaft 224 for mutual hinge connection. One end of the adjusting rod 24 is provided with a connecting hole sleeved on the first hinge shaft 224. The support frame 21 is provided with a sliding hole for the adjusting rod 24 to pass through and slide axially. The support frame 21 is provided with a cantilever 211 at the second hinge end 223 of the first refracting plate 22 and the second refracting plate 23 respectively. The cantilever 211 is provided with a sliding groove 212 perpendicular to the axis of the adjusting rod 24. The second hinge end 223 of the first refracting plate 22 and the second refracting plate 23 are provided with a second hinge shaft 225. The second hinge shaft 225 of the first refracting plate 22 and the second refracting plate 23 are respectively inserted into the sliding groove 212 of the adjacent cantilever 211 for sliding engagement. The end of the adjusting rod 24 that passes through the sliding hole is provided with a pin 241 in the radial direction. The support frame 21 is provided with a guide groove perpendicular to the axial direction of the adjusting rod 24. The driving plate 25 is inserted into the guide groove for sliding engagement. The driving plate 25 is provided with a plurality of driving grooves 251 corresponding to the position of the pin 241 of each adjusting rod 24. The pin 241 extends into the corresponding driving groove 251 for sliding engagement. The drive plate 25 has a rack 252 on one side. The output shaft of the drive motor 26 is coaxially linked with the drive gear 27. The drive gear 27 meshes with the rack 252. Each drive motor 26 is connected to the PLC controller signal and controls the start, stop and forward / reverse rotation according to the signals of each light sensor 32.

[0027] When the angle of sunlight passes through window 15 and reaches the top surface of the overlay layer 14, sunlight cannot directly project into the side window 15, resulting in a decrease in the lighting effect of the gymnasium.

[0028] Therefore, by using the external refracting device 2, as shown in the instruction manual... Figure 4-7As shown, the PLC controller controls the start, stop, forward and reverse rotation of each drive motor 26, thereby driving the drive plate 25 to move via the rack 252. When the drive plate 25 slides along the guide groove of the support frame 21, the drive groove 251 on the drive plate 25 drives the pin 241 to move, which in turn pushes and pulls the first hinge shaft 224 via the adjusting rod 24. With the support and sliding of the cantilever 211 slide groove 212 and the second hinge shaft 225, the angle between the first refracting plate 22 and the second refracting plate 23 is ultimately controlled, as shown in the attached instruction manual. Figure 8 As shown, the angle between the first and second refracting plates 23 is adjusted according to the angle of sunlight, so that sunlight is guided and refracted into the window 15 of the cover layer 14, which makes up for the problem of insufficient light in the gymnasium after the cover layer 14 blocks direct sunlight.

[0029] A further feature of the present invention is that both the first refracting plate 22 and the second refracting plate 23 include a refractive surface facing the side of the cover layer 14 and a dark surface facing outwards.

[0030] The annular refracting plate 31 includes a refractive surface facing the roof 12 and a dark surface facing the bottom plate. A lighting component is provided on the dark surface of the annular refracting plate 31 facing the ground.

[0031] Setting a dark side avoids unnecessary refraction.

[0032] By setting up the roof lighting structure of the gymnasium in this application, the insufficient brightness and uneven brightness distribution inside the gymnasium can be compensated for by the addition of the cover layer 14 blocking direct sunlight, even when the large-area building lighting opening 13 is not covered by a transparent material.

[0033] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Therefore, any variations, additions, or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this invention should be included within the protection scope of this invention. Thus, the protection scope of this invention should be determined by the scope of the claims.
