Description

Technical Field

[0001] This invention relates to the field of industrial ventilation and environmental control technology, and in particular to an automatically adjustable louver suitable for industrial plants. Background Technology

[0002] During industrial production, a large amount of heat, dust and harmful gases are often generated in the factory. Good ventilation and precise temperature control are crucial for production safety and worker health. At present, most of the louvers used in industrial plants are manually adjustable or fixed angle type. Fixed-angle louvers cannot flexibly adjust to real-time environmental parameters such as temperature and dust concentration inside the factory. When the temperature inside the factory is too high or the dust concentration exceeds the standard, they cannot effectively enhance ventilation. Furthermore, they cannot be closed in time to prevent outside debris from entering the factory during severe weather such as strong winds or heavy rain. In addition, the materials and structure of ordinary louvers are ill-suited to the harsh environment of industrial plants, making them prone to damage and with a short lifespan, leading to increased maintenance costs. Manually adjusting louvers requires regular operation by staff, which is not only labor-intensive, but also extremely inconvenient to adjust in large factories due to their high position, making it difficult to adjust them in a timely manner according to real-time environmental changes. In addition, due to the special nature of their application environment, the windows designed for factories are large in size, resulting in a large overall length of louvers. If they are not locked after being closed, they are prone to self-rotation and opening due to strong airflow; if they are locked, the middle part of the louvers will deform and swing, creating gaps for water leakage and swinging noise. Therefore, there is an urgent need for a type of louver that can adapt to the industrial plant environment and automatically adjust according to real-time internal environmental parameters. Summary of the Invention

[0003] The purpose of this invention is to provide an automatically adjustable louver suitable for industrial plants, so as to solve the problems mentioned in the background art.

[0018] This invention provides, for example Figure 1 - Figure 8 The diagram shows an automatically adjustable louver suitable for industrial plants, including a louver frame 1 and louver blades 2 rotatably disposed inside the louver frame 1. An environmental monitoring box 3 is installed at the top of the louver frame 1, and a drive mechanism 5 is installed inside the louver frame 1. The drive mechanism 5 is connected to the louver blades 2 via a transmission connection. The drive mechanism 5 is connected to a control box 6 via a signal line. The environmental monitoring box 3 is connected to the control box 6 via a communication connection, so that the control box 6 generates a control signal for driving the louver blades 2 to adjust their angle based on the detection data of the environmental monitoring box 3. The drive mechanism 5 includes a dual-axis motor 51, an anti-sway traction mechanism 52, and a self-locking drive unit 53. The anti-sway traction mechanism 52 and the self-locking drive unit 53 are both connected to the dual-axis motor 51. The self-locking drive unit 53 is connected to both ends of the louver blade 2 to drive the louver blade 2 to rotate. The anti-sway traction mechanism 52 is connected to the middle part of the louver blade 2 so that the middle part of the louver blade 2 is prevented from swaying and causing leakage and collision noise under strong airflow conditions.

[0019] A dust concentration sensor 32 and a temperature sensor 33 are fixedly installed on the inner side of the environmental monitoring box 3. A wind speed sensor 34 and a rainfall sensor 35 are fixedly installed on the outer side of the environmental monitoring box 3. The sensing ends of the wind speed sensor 34 and the rainfall sensor 35 penetrate through the outer wall of the louver window frame 1. A plugged wire 4 for powering the environmental monitoring box 3 and the dual-axis motor 51 is installed on the side of the environmental monitoring box 3.

[0020] Both ends of the louver blade 2 are fixedly welded with a rotating shaft 22. The rotating shaft 22 is rotatably set on the inner side wall of the louver window frame 1. The side wall of the louver window frame 1 is hollow. The self-locking drive unit 53 is installed in the inner cavity on both sides of the louver window frame 1.

[0021] The self-locking drive unit 53 includes a worm gear 531 rotatably mounted on the inner top of both sides of the louver frame 1. A worm wheel 534 meshing with the worm gear 531 is rotatably mounted below the worm gear 531. A drive gear 535 is coaxially fixedly mounted on one side of the worm wheel 534. A composite rack 536 is slidably mounted on both sides of the louver frame 1. A transmission gear 539 is fixedly sleeved on the outer wall of the rotating shaft 22. The two ends of the composite rack 536 mesh with the drive gear 535 and the transmission gear 539 respectively, so that the worm gear 531 drives multiple rotating shafts 22 to rotate synchronously.

[0022] The louver window frame 1 is internally fixedly connected to a mounting shaft 532. The outer wall of the mounting shaft 532 is connected to a bearing sleeve 533. The worm gear 534 and the drive gear 535 are both fixedly sleeved on the outer wall of the bushing 533. The top of the composite rack 536 is provided with an upper tooth groove 537 that meshes with the drive gear 535. The lower end of the composite rack 536 is provided with a lower tooth groove 538 that meshes with the transmission gear 539. The arrangement directions of the upper tooth groove 537 and the lower tooth groove 538 are perpendicular.

[0023] The louver window frame 1 is fixedly provided with a guide rail 5310. The top of the guide rail 5310 is integrally formed with an upper limit sleeve 5311. The drive gear 535 is rotatably set in the upper limit sleeve 5311. The lower end of the guide rail 5310 is integrally formed with multiple lower limit sleeves 5312. The transmission gear 539 is rotatably connected in the lower limit sleeves 5312. The back of the composite rack 536 is integrally formed with a limit strip 5314. The outer wall of the guide rail 5310 is provided with a limit groove 5313 that matches the limit strip 5314. The two ends of the limit groove 5313 extend into the upper limit sleeve 5311 and the lower limit sleeve 5312 respectively, so that the composite rack 536 can pass through the upper limit sleeve 5311 and the lower limit sleeve 5312 along the limit groove 5313.

[0024] A dual-axis motor 51 is fixedly installed on the inner top of the louver window frame 1, and a drive shaft 54 ​​is fixedly installed on both output ends of the dual-axis motor 51. A worm gear 531 is fixedly sleeved on the outer surface of the drive shaft 54. A support shaft seat 55 is connected to the end bearing of the drive shaft 54. The support shaft seat 55 is fixedly installed in the louver window frame 1. The anti-sway traction mechanism 52 is connected to the drive shaft 54.

[0025] The anti-sway traction mechanism 52 includes a traction rope 521. Both ends of the traction rope 521 extend upward from the inner bottom of the louver window frame 1 and are fixedly fixed through multiple louver blades 2. Both ends of the traction rope 521 extend to the inner top of the louver window frame 1. A sprocket 522 is fixedly installed on the outer wall of the drive shaft 54. An open chain 523 is mounted on the sprocket 522. Both ends of the open chain 523 are fixedly installed with the two ends of the traction rope 521.

[0026] A positioning shaft 524 is fixedly installed at the inner bottom of the louver frame 1. A fixed pulley 525 is connected to the outer surface bearing of the positioning shaft 524. The traction rope 521 passes around the outer surface of the fixed pulley 525 so that the two ends of the traction rope 521 can be displaced by the same distance in opposite directions, thereby pulling the louver blades 2 to rotate around the rotating shaft 22.

[0027] The louver blades 2 are made of aluminum-zinc coated steel plates, and the louver window frame 1 is made of weathering steel. When the louver blades 2 are closed, their outer sides flip downwards, and the traction rope 521 is clamped between two adjacent sets of louver blades 2 to form a noise reduction effect, so that rainwater can flow down along multiple louver blades 2 in sequence.

[0028] Working principle: When in use, the environmental monitoring box 3 monitors the temperature, dust concentration and outside wind speed in the factory in real time, and transmits the detected signals to the control box 6. When the indoor temperature is below 35℃, the dust concentration is below 2mg / m³, the outside wind speed is below 8m / s, and the outside instantaneous rainfall is less than 2.5 mm / h, the outer ends of the louver blades 2 are in a preset downward tilted state, so that an outward and downward tilted exhaust channel is formed between multiple louver blades 2 for daily exhaust function.

[0029] When the temperature inside the factory exceeds 35℃ or the dust concentration exceeds 2mg / m³, and the outside wind speed is below 8m / s and the outside instantaneous rainfall is less than 2.5 mm / h, the control box 6 issues a command to control the dual-axis motor 51 to rotate. At this time, the dual-axis motor 51 drives the rotating shaft 22 to rotate through the self-locking drive unit 53. At the same time, the anti-sway traction mechanism 52 pulls the middle of the louver blade 2 to rotate synchronously, so that the louver blade 2 is in a horizontal state. At this time, the ventilation gap of the louver window frame 1 reaches the maximum value, thereby enhancing the ventilation inside the factory. When the outside wind speed exceeds 8 m / s or the instantaneous rainfall is greater than 2.5 mm / h, the control box 6 controls the dual-axis motor 51 to rotate in the opposite direction, driving the louver blades 2 to rotate to the closed state. At this time, the outer side of the louver blades 2 tilts downward and fits against the top of the louver blades 2 below, so that multiple louver blades 2 form a continuous downward water guiding structure, similar to the state of roof tiles, thus preventing strong winds from blowing debris into the factory building and preventing water from entering. Under the action of the traction rope 521, on the one hand, it can prevent the louver blades 2 from deforming and shaking in the middle due to excessive length. On the other hand, the traction rope 521 is clamped between two adjacent louver blades 2, thus preventing the louver blades 2 from colliding with each other and generating noise when shaking. The specific drive stroke of drive mechanism 5 is as follows; The dual-axis motor 51 starts, driving the drive shaft 54 ​​to rotate. The drive shaft 54 ​​drives the worm gear 531 to rotate, which in turn drives the worm wheel 534 to rotate. The worm wheel 534 rotates synchronously with the drive gear 535, thereby driving the composite rack 536 to move vertically along the limiting groove 5313. The composite rack 536 meshes with the transmission gear 539 through the lower tooth groove 538 at its lower end, thereby causing the rotating shaft 22 to drive the louver blades 2 to rotate and change their tilt angle. At the same time, as the drive shaft 54 ​​rotates, it drives the sprocket 522 to rotate. The sprocket 522 drives the open chain 523 to move. The open chain 523 drives the two ends of the traction rope 521 to move synchronously in opposite directions, thereby causing the traction rope 521 to synchronously pull the middle part of the louver blades 2 to rotate synchronously with the rotating shaft 22 at the same angle, and using the traction rope 521 to maintain the angle of the middle part of the louver blades 2. During the design and manufacture of this device, it is important to note that the diameter of the sprocket 522 and the diameter and gear ratio of the transmission gear 539 need to be designed and adjusted to ensure that the rotation amplitude of the shaft 22 is the same as the rotation amplitude of the middle part of the louver blade 2; at the same time, by designing the direction of the thread groove of the worm 531, it is ensured that the rotation direction of the transmission gear 539 is the same as that of the sprocket 522.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
