Description

Technical Field

[0001] This invention belongs to the field of building lighting technology, and in particular relates to a skylight for factory buildings that is easy to adjust in angle. Background Technology

[0002] As the core production site, ventilation, smoke extraction, and natural lighting are key requirements for ensuring production efficiency, operational safety, and personnel comfort in industrial plants. As the core ventilation and lighting component on the roof of the plant, the performance of skylights directly affects the plant's operational quality and energy consumption costs.

[0003] A search revealed Chinese Patent Publication No. CN101509304B, which discloses a horizontal sunken skylight structure for a frame-type industrial plant. This structure comprises two skylight components, each composed of multiple skylight components with a predetermined span and trapezoidal outer contours. The two skylight components are erected on top of the plant's columns and vertically positioned in the plant's horizontal direction. The two skylight components are connected by purlins with a predetermined spacing and are parallel to each other. Each component has an eaves board at its top. Skylight assemblies are located on opposite sides of each of the two skylight components. Each skylight assembly includes upper and lower skylight rails and a window sash. The window sash is located between the upper and lower skylight rails, and its top is movably connected to the upper skylight rail. An upper skylight rail plate is located between the upper skylight rail and the eaves board above it. Supporting components and roof panels are located between the upper chords and lower parts of the two skylight components, respectively. A lower skylight rail plate is located between the roof panel and the lower skylight rail. A roof surface layer is laid on the roof panel. This invention features good lighting and ventilation, energy saving, reliability, and earthquake resistance in factory buildings under specific conditions.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing factory skylights mostly employ manual traction ropes, single push rods, or fixed angle designs. Manual adjustment requires operators to climb to heights, resulting in high labor intensity, low adjustment accuracy, and the inability to achieve remote or multi-point synchronous adjustment. Electric adjustment methods mostly use a single drive structure, which is prone to jamming and deviation during adjustment, making it difficult to adjust and unable to simultaneously meet ventilation efficiency and energy-saving requirements.

[0005] Therefore, the present invention provides a skylight for factory buildings that is easy to adjust in angle, in order to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a skylight for factory buildings that is easy to adjust in angle in order to solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a skylight for factory buildings that is easy to adjust in angle, comprising a frame, wherein heat-insulating glass is fixedly installed on the upper surface and the inner walls at both ends of the frame, and mounting plates are fixedly installed on both side walls of the frame;

[0017] The reciprocating screw has a threaded sleeve installed on its outer surface, and a scraper is fixedly installed on the lower surface of the threaded sleeve. The lower surface of the scraper is in contact with the upper surface of the heat-insulating glass on the upper surface of the frame.

[0018] As a further description of the above technical solution:

[0019] A driven sprocket is fixedly mounted on the outer surface of the reciprocating screw, and a driving sprocket is fixedly mounted on the outer surface of the rotating rod. The driving sprocket and the driven sprocket are connected by a sprocket drive.

[0020] As a further description of the above technical solution:

[0021] A sliding ring plate is fixedly installed at one end of the supporting spring. The outer surface of the sliding ring plate is slidably connected to the inner wall of the chamber, and a connecting ring is fixedly installed on the lower surface of the sliding ring plate.

[0022] As a further description of the above technical solution:

[0023] One end of the connecting ring extends to the lower surface of the frame, and a sealing ring strip is fixedly installed on the lower surface of the connecting ring. The sealing ring strip is made of EPDM rubber and has a hollow arc-shaped cross-section.

[0028] As a further description of the above technical solution:

[0029] A positioning rod is rotatably mounted on the inner wall of the rotating cylinder. One end of the positioning rod extends into the interior of the rotating cylinder and is fixedly mounted with a movable bevel gear. The movable bevel gear meshes with the fixed bevel gear. The other end of the positioning rod extends into the exterior of the rotating cylinder and is fixedly mounted with a fan blade.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] 1. In this invention, by setting an adjustment mechanism, during the use of the skylight, the servo motor drives the rotating rod to rotate under the limit of the mounting sleeve according to the weather conditions or the required opening angle. As the rotating rod rotates, it drives the sealing glass to rotate synchronously through the connecting strip. When the sealing glass rotates, it drives the limiting groove to move under the limit of the limiting block, thereby limiting the sealing glass and realizing the adjustable function of the skylight. There is no need for manual adjustment, which reduces the steps for operators to work at height and reduces the labor intensity of operators. At the same time, it directly contacts the drive structure and operates under the limit of the limiting groove and the limiting block, further improving the adjustment accuracy of the skylight. In addition, it can be used with sensors and other components to enable the skylight to quickly and accurately adjust the opening angle according to the real-time changes of temperature, humidity and flue gas concentration in the factory, ensuring the ventilation efficiency and energy-saving requirements of the factory.

[0032] 2. In this invention, by setting a sealing mechanism, the heat-insulating glass is installed on the frame. At this time, the sealing ring is installed between the frame and the factory building. The support spring moves downwards from the frame, so that the sliding slide moves the sealing ring downwards from the frame through the connecting ring. This allows the sealing ring to fill the gap between the frame and the factory building, reducing the gap at the connection between the skylight and the factory building. This effectively prevents the skylight from leaking and further improves the sealing effect of the skylight.

[0033] 3. In this invention, a scraping mechanism is provided. Under the action of the driven toothed sprocket, the reciprocating screw rotates inside the positioning sleeve. As the reciprocating screw rotates, the threaded sleeve moves back and forth outside the reciprocating screw. At this time, the threaded sleeve drives the scraper to move back and forth on the heat-insulating glass, thereby cleaning the heat-insulating glass above the frame, ensuring the light transmittance of the heat-insulating glass, further improving the light intensity inside the factory, and at the same time scraping away accumulated rainwater to avoid leakage due to long-term accumulation of rainwater, further ensuring the stability of the skylight.

[0034] 4. In this invention, an exhaust mechanism is provided. As the rotating cylinder rotates, the positioning rod drives the fan blades to rotate synchronously. The rotation of the fan blades enables the circulation of gas inside the factory. Depending on the required exhaust speed, the motor can be controlled to drive the drive rod to rotate inside the rotating cylinder. At this time, the drive rod drives the fixed bevel gear to rotate. As the fixed bevel gear rotates, the positioning rod drives the fan blades to rotate under the action of the movable bevel gear, thereby adjusting the angle of the fan blades. This improves the ventilation efficiency of the exhaust mechanism without increasing the power of the stepper motor, achieving energy saving and meeting the development needs of modern industrial plants for greening, intelligence, and high efficiency.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In specific implementation, such as Figures 1-8 As shown, the present invention provides a technical solution: a skylight for factory buildings that is easy to adjust in angle, including a frame 1, with heat-insulating glass 2 fixedly installed on the upper surface and the inner walls at both ends of the frame 1, and mounting plates fixedly installed on both side walls of the frame 1.

[0047] Adjustment mechanism 3 is set on both side walls of frame 1. Adjustment mechanism 3 includes a rotating rod 301. An installation sleeve 302 is rotatably mounted on the outer surface of the rotating rod 301. The installation sleeve 302 is symmetrically fixedly mounted on both side walls of frame 1. A connecting frame 306 is fixedly mounted on the side wall of frame 1. A servo motor 305 is fixedly mounted on the side wall of the connecting frame 306. The output end of the servo motor 305 is fixedly connected to one end of the rotating rod 301.

[0048] A connecting strip 303 is fixedly installed on the outer surface of the rotating rod 301, and a sealing glass 304 is fixedly installed on the lower surface of the connecting strip 303. The sealing glass 304 is compatible with the frame 1.

[0049] A limiting groove 307 is fixedly installed on the side wall of the sealed glass 304, and a limiting block 308 is slidably installed on the inner wall of the limiting groove 307. One end of the limiting block 308 is fixedly connected to the inner surface of the frame 1.

[0050] Specifically, by setting the adjustment mechanism 3, during the use of the sunroof, the servo motor 305 can drive the rotating rod 301 to rotate under the limit of the mounting sleeve 302 according to the weather conditions or the required opening angle. As the rotating rod 301 rotates, it will drive the sealing glass 304 to rotate synchronously through the connecting strip 303. When the sealing glass 304 rotates, it will drive the limiting groove 307 to move under the limit of the limiting block 308, thereby limiting the sealing glass 304.

[0051] The scraping mechanism 4 is located on the upper surface of the frame 1. The scraping mechanism 4 includes a reciprocating screw 401, which is symmetrically distributed above the frame 1. The outer surface of the reciprocating screw 401 is provided with half of the thread, which is symmetrically distributed. A positioning sleeve 402 is rotatably installed on the outer surface of the reciprocating screw 401. The lower surface of the positioning sleeve 402 is fixedly connected to the upper surface of the frame 1.

[0052] A threaded sleeve 403 is threaded on the outer surface of the reciprocating screw 401. A scraper 404 is fixedly installed on the lower surface of the threaded sleeve 403. The lower surface of the scraper 404 is in contact with the upper surface of the heat-insulating glass 2 on the upper surface of the frame 1.

[0053] A driven sprocket 405 is fixedly mounted on the outer surface of the reciprocating screw 401, and a drive sprocket 406 is fixedly mounted on the outer surface of the rotating rod 301. The drive sprocket 406 and the driven sprocket 405 are connected by a sprocket drive.

[0054] Specifically, by setting up the scraping mechanism 4, during the window opening process, the rotating rod 301 will drive the drive sprocket 406 to rotate. Under the transmission of the sprocket, the driven sprocket 405 will rotate synchronously. Under the action of the driven sprocket 405, the reciprocating screw 401 will rotate inside the positioning sleeve 402. As the reciprocating screw 401 rotates, the threaded sleeve 403 will move back and forth outside the reciprocating screw 401. At this time, the threaded sleeve 403 will drive the scraper 404 to move back and forth on the heat-insulating glass 2, thereby cleaning the heat-insulating glass 2 above the frame 1 and ensuring the light transmittance of the heat-insulating glass 2.

[0055] The exhaust mechanism 5 is located inside the heat-insulating glass 2. The exhaust mechanism 5 includes a mounting frame 501. The mounting frame 501 has a through groove inside. A fixing bracket 502 is fixedly installed on the inner wall of the through groove. A stepper motor 503 is fixedly installed on the side wall of the fixing bracket 502.

[0056] A connecting rod 504 is fixedly installed at the output end of the stepper motor 503. One end of the connecting rod 504 extends into the interior of the mounting frame 501 through the fixing bracket 502. A rotating cylinder 505 is fixedly installed at one end of the connecting rod 504.

[0057] A conductive ring 506 is fixedly installed on the outer surface of the rotating cylinder 505, and a control motor 507 is fixedly installed on the inner wall of the rotating cylinder 505. A drive rod 508 is fixedly installed at the output end of the control motor 507, and a fixed bevel gear 509 is fixedly installed on the outer surface of the drive rod 508. The conductive ring 506 and the control motor 507 are electrically connected by wires.

[0058] A positioning rod 5010 is rotatably mounted on the inner wall of the shell cavity of the rotating cylinder 505. One end of the positioning rod 5010 extends into the interior of the rotating cylinder 505 and is fixedly mounted with a movable bevel gear 5011. The movable bevel gear 5011 meshes with the fixed bevel gear 509. The other end of the positioning rod 5010 extends into the exterior of the rotating cylinder 505 and is fixedly mounted with a fan blade 5012.

[0059] Specifically, by setting up the exhaust mechanism 5, when ventilation and exhaust are required inside the factory, the stepper motor 503 drives the rotating cylinder 505 to rotate within the mounting frame 501 via the connecting rod 504. As the rotating cylinder 505 rotates, it drives the fan blade 5012 to rotate synchronously via the positioning rod 5010. The rotation of the fan blade 5012 enables the circulation of gas inside the factory. Depending on the required exhaust speed, the drive rod 508 can be driven to rotate inside the rotating cylinder 505 by controlling the motor 507. At this time, the drive rod 508 will drive the fixed bevel gear 509 to rotate. As the fixed bevel gear 509 rotates, the positioning rod 5010 drives the fan blade 5012 to rotate under the action of the movable bevel gear 5011, thereby adjusting the angle of the fan blade 5012 and improving the ventilation efficiency of the exhaust mechanism 5 without increasing the power of the stepper motor 503.

[0060] The sealing mechanism 6 is located inside the shell cavity of the frame 1. The sealing mechanism 6 includes a chamber 601, which is located inside the shell cavity of the frame 1. The chamber 601 is configured as a square annular channel, and a support spring 602 is fixedly installed on the inner wall of the top surface of the chamber 601.

[0061] A sliding ring plate 603 is fixedly installed at one end of the supporting spring 602. The outer surface of the sliding ring plate 603 is slidably connected to the inner wall of the chamber 601. A connecting ring 604 is fixedly installed on the lower surface of the sliding ring plate 603.

[0062] One end of the connecting ring 604 extends to the lower surface of the frame 1. A sealing ring 605 is fixedly installed on the lower surface of the connecting ring 604. The sealing ring 605 is made of EPDM rubber and has a hollow arc-shaped cross section.

[0063] Specifically, by setting the sealing mechanism 6, the heat-insulating glass 2 is installed on the frame 1. At this time, the sealing ring 605 will be installed between the frame 1 and the factory building. The support spring 602 will move downwards from the frame 1, so that the sliding slide can drive the sealing ring 605 downwards from the frame 1 through the connecting ring 604, so that the sealing ring 605 fills the gap between the frame 1 and the factory building.

[0064] Working principle: Place the frame 1 in a suitable position in the factory building, and then fix the mounting plate with bolts to install the frame 1 on the factory building. Then install the heat-insulating glass 2 on the frame 1. At this time, the sealing ring 605 will be installed between the frame 1 and the factory building. The support spring 602 will move downwards from the frame 1, so that the sliding plate will drive the sealing ring 605 to move downwards from the frame 1 through the connecting ring 604, so that the sealing ring 605 fills the gap between the frame 1 and the factory building.

[0065] During the use of the sunroof, depending on the weather conditions or the required opening angle, the servo motor 305 drives the rotating rod 301 to rotate under the limit of the mounting sleeve 302. As the rotating rod 301 rotates, it drives the sealing glass 304 to rotate synchronously through the connecting strip 303. When the sealing glass 304 rotates, it drives the limiting groove 307 to move under the limit of the limiting block 308, thereby limiting the sealing glass 304.

[0066] During the window opening process, the rotating rod 301 drives the drive sprocket 406 to rotate. Under the transmission of the sprocket, the driven sprocket 405 rotates synchronously. Under the action of the driven sprocket 405, the reciprocating screw 401 rotates inside the positioning sleeve 402. As the reciprocating screw 401 rotates, the threaded sleeve 403 moves back and forth outside the reciprocating screw 401. At this time, the threaded sleeve 403 drives the scraper 404 to move back and forth on the heat-insulating glass 2, thereby cleaning the heat-insulating glass 2 above the frame 1 and ensuring the light transmittance of the heat-insulating glass 2.

[0067] When ventilation and exhaust are required inside the factory, the stepper motor 503 drives the rotating cylinder 505 to rotate within the mounting frame 501 via the connecting rod 504. As the rotating cylinder 505 rotates, it drives the fan blades 5012 to rotate synchronously via the positioning rod 5010. The rotation of the fan blades 5012 facilitates the circulation of gas inside the factory. Depending on the required exhaust speed, the drive rod 508 can be driven to rotate inside the rotating cylinder 505 by the control motor 507. At this time, the drive rod 508 drives the fixed bevel gear 509 to rotate. As the fixed bevel gear 509 rotates, the positioning rod 5010 drives the fan blades 5012 to rotate under the action of the movable bevel gear 5011, thereby adjusting the angle of the fan blades 5012 and improving the ventilation efficiency of the exhaust mechanism 5 without increasing the power of the stepper motor 503.

[0068] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
