[0041] 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.

[0042] See Figure 1-11As shown, a modular, split-type double-track fireproof roller shutter door includes a mounting base frame 100 connected to a wall. Two curtain panels 300 are located below the mounting base frame 100. A winding module for winding the curtain panels 300 is provided within the mounting base frame 100. The winding module includes two winding rollers 500, which are connected to the curtain panels 300 via a first detachable component. The two winding rollers 500 are connected to a winding drive component for rotating them. The winding drive component drives the two winding rollers 500 to rotate synchronously, thereby winding the two curtain panels 300. The lower ends of the two curtain panels 300 are connected to a curtain panel seat 600. The wall on both sides of the frame 100 is equipped with track modules corresponding to the curtain panel 300. The curtain panel seat 600 has an avoidance notch in the middle. This double curtain panel 300 configuration forms an air gap, which further improves the isolation effect. A clearing support module 400 is provided on the ground where the mounting base frame 100 is located. The clearing support module 400 matches the curtain panel seat 600. The clearing support module 400 can move the object stuck in the isolation position and lock it with the curtain panel seat 600. The support area of ​​the clearing support module 400 is larger than the area of ​​the curtain panel seat 600 so as to move the impurities to outside the docking position.

[0043] The mounting frame 100 is also equipped with a spray module, which can spray water into the room and onto the curtain panel 300, increasing the probability of personnel escape and cooling the surface of the curtain panel 300, thus improving its fire resistance. The spray module includes a water tank 200 mounted on the mounting frame 100, which stores water. A water supply pipe 201 is located on the outside of the water tank 200, and a one-way valve 202 is installed on the water supply pipe 201. An air inlet device is also provided at the air inlet of the water tank 200 to inflate the interior of the tank, ensuring adequate airflow. Under high pressure, it is convenient to spray water after a fire is triggered, since there may be insufficient power supply during a fire. The drain end of the water tank 200 is connected to the first sprinkler head group 205 through the water supply pipe 203. The first sprinkler head group 205 is equipped with a main sprinkler pipe 204 that sprays water towards the room and a second sprinkler head group 206 that sprays water towards the curtain panel 300. Both the main sprinkler pipe 204 and the second sprinkler head group 206 are fire sprinklers. In the event of a fire, the main sprinkler pipe 204 and the second sprinkler head group 206 spray a large amount of water, which improves the isolation and protection effect and also helps to increase people's escape probability.

[0044] The mounting base 100 is also equipped with a smoke removal module. The smoke removal module includes a smoke collection box 101 installed on the inner wall of the mounting base 100. An air intake grille 102 is provided on the outer side of the smoke collection box 101. The exhaust end of the smoke collection box 101 is connected to an exhaust fan 103. The exhaust end of the exhaust fan 103 is connected to a smoke delivery duct 104. The smoke delivery duct 104 passes through the wall and connects to the outside. In this way, when a fire occurs, the smoke will appear at the top of the room. At this time, the exhaust fan 103 will work to exhaust the smoke from the room, which will facilitate the observation of the rescue direction.

[0045] The obstacle clearing support module 400 includes two mounting bases 408, with two transmission rollers 409 rotatably mounted between the two mounting bases 408. A transmission belt 403 is driven between the two transmission rollers 409. A first arc plate seat 401 and a second arc plate seat 402, matching the ends of the transmission rollers 409, are provided on both sides of the mounting bases 408, allowing the transmission belt 403 to be flush with the ground and reducing the installation gap. A rolling support member is provided between the two mounting bases 408 to support the upper transmission roller 409. The transmission roller 409 is connected to the take-up roller 500 via a transmission unit. A locking structure is provided between the mounting bases 408 and the curtain plate seat 600, thus ensuring that the curtain plate seat... After 600 descends to the lowest point, the locking structure locks the curtain panel seat 600 and the obstacle clearing support module 400, thereby completing the automatic locking of the bottom of the curtain panel 300. The outer side of the mounting base 408 is also provided with an unlocking component to unlock the locking structure. When the curtain panel 300 is rolled up, the unlocking component will automatically unlock. It should be noted that when the curtain panel seat 600 and the obstacle clearing support module 400 are locked, there is a certain distance between the lower end of the locking slider 523 and the upper end surface of the curtain panel seat 600. This way, there will be no interference when the curtain panel 300 is rolled up. During the upward movement of the curtain panel seat 600, the locking slider 523 will be quickly retracted into the locking platform 524, without affecting the continued upward movement of the curtain panel seat 600.

[0046] The locking structure includes locking grooves 605 at both ends of the curtain seat 600. The upper end of the mounting base 408 is provided with a locking platform 524 corresponding to the locking grooves 605. The upper end of the locking platform 524 is provided with a guide platform 521. The middle position of the locking platform 524 is provided with a mounting cavity. The outer side of the locking platform 524 is provided with an extension opening 522. A locking slider 523 is slidably provided in the extension opening 522. The locking slider 523 is connected to the inner wall of the mounting cavity by a locking spring 520. The end of the locking slider 523 is a trapezoidal structure. When the curtain seat 600 moves down, under the guidance of the guide platform 521, the locking platform 524 will smoothly pass through the locking groove 605. Under the action of the inclined surface at the end of the locking slider 523, the locking slider 523 will retract into the locking platform 524. Then, under the action of the locking spring 520, the locking slider 523 will pop out, completing the locking of the curtain seat 600.

[0047] The unlocking component includes a side rod 525 disposed outside the locking slider 523. An unlocking connecting rod 519 is rotatably mounted at one end of the side rod 525. The other end of the unlocking connecting rod 519 is rotatably connected to a linkage pin 518. The linkage pin 518 is fixedly mounted at an eccentric position on the unlocking wheel 517. The unlocking wheel 517 is fixedly connected to one end of the unlocking shaft. The other end of the unlocking shaft is connected to an unlocking umbrella block 508. The unlocking shaft is rotatably mounted on an auxiliary frame on the mounting base 408. The unlocking umbrella block 508 is connected to the take-up roller. In the 500-linkage mechanism, the unlocking umbrella block 508 engages with the outer side of the second transmission wheel 509. When the second transmission wheel 509 rotates, the unlocking umbrella block 508 is driven by the unlocking umbrella block 508, thereby driving the unlocking wheel 517 to rotate. The unlocking wheel 517 rotates through the linkage pin 518, and the linkage pin 518 drives the locking slider 523 to retract into the locking platform 524 through the unlocking connecting rod 519, thus completing the unlocking. Here, because the transmission circumference of the unlocking umbrella block 508 is limited, it will not drive the unlocking connecting rod 519 to rotate excessively, and there will be no interference problem.

[0048] The transmission unit includes a second transmission shaft 514 disposed at the shaft end of the transmission roller 409, a fourth transmission wheel 512 disposed at the end of the second transmission shaft 514, and a unidirectional ratchet disposed between the second transmission shaft 514 and the fourth transmission wheel 512. A support plate 526 is also disposed on the outer side of the mounting base 408, and a first transmission shaft 510 is rotatably disposed on the support plate 526. A third transmission wheel 511 is disposed at one end of the first transmission shaft 510, and the third transmission wheel 511 is connected to the fourth transmission wheel 512 by a second transmission belt 513. A second transmission wheel 509 is disposed at the other end of the first transmission shaft 510. A first transmission wheel 506 is disposed at the shaft end of the take-up roller 500, and a ratchet is disposed between the first transmission wheel 506 and the second transmission wheel 509. The winding roller 500 rotates via the first drive belt 507, which in turn drives the first drive wheel 506 to rotate. The first drive wheel 506 drives the second drive wheel 509 to rotate via the first drive belt 507. The second drive wheel 509 drives the third drive wheel 511 to rotate via the first drive shaft 510. The third drive wheel 511 drives the fourth drive wheel 512 to rotate via the second drive belt 513. The fourth drive wheel 512 drives the transfer roller 409 to rotate. Thus, when the curtain 300 is lowered, the winding roller 500 drives the first drive wheel 506 to rotate, thereby causing the transfer belt 403 to rotate. This allows items placed on the transfer belt 403 to be transferred away. This transfer can transfer both small particulate impurities and large volume impurities together.

[0049] When the curtain plate seat 600 and the curtain plate 300 rise, the conveyor belt 403 remains stationary due to the unidirectional transmission of the ratchet.

[0050] The rolling support includes a horizontally arranged support frame 406. Multiple support roller shafts 405 are rotatably arranged at the notch at the upper end of the support frame 406. The multiple support roller shafts 405 form a rolling surface. A support foot 407 is provided around the support frame 406. The rolling surface supports the transmission roller 409, so that the transmission roller 409 has sufficient support force.

[0051] The track module includes two guide rails 301 symmetrically arranged on the wall. Adjacent guide rails 301 are connected by reinforcing rods 302. The reinforcing rods 302 are connected to the wall by expansion screws. The guide rails 301 have track grooves 303 on the side facing the curtain panel 300. The outer side of the curtain panel 300 has auxiliary sliders that match the track grooves 303. Under the guidance of the guide rails 301, the curtain panel 300 can be raised and lowered more smoothly. The upper end of the track grooves 303 has a chamfer to make the connection between the auxiliary sliders and the guide rails 301 smoother.

[0052] The curtain panel seat 600 and the curtain panel 300 are connected by a second detachable component. The second detachable component includes a second plate seat block 603 disposed on the upper end of the curtain panel seat 600 and a first plate seat block 602 fixed on the inner side of the curtain panel 300. A plate seat pin 601 is threaded on the second plate seat block 603. The end of the plate seat pin 601 corresponds to the through hole on the first plate seat block 602. A pull ring 604 is provided at the end of the plate seat pin 601. During installation, the curtain panel 300 is first set vertically, and the lower end of the curtain panel 300 is connected to the curtain panel seat 600. Then, the pull ring 604 is rotated to insert the plate seat pin 601 into the first plate seat block 602 to complete the connection of the curtain panel seat 600, which facilitates the subsequent disassembly and maintenance.

[0053] The winding drive component includes winding gears 501 disposed at the ends of two winding rollers 500, the two winding gears 501 meshing with each other, and a worm gear 505 coaxially disposed at the end of one of the winding rollers 500. The upper side of the worm gear 505 meshes with a worm 502. The worm 502 is connected to the output end of a drive motor 504 via a drive shaft 503. The drive motor 504 is mounted inside the mounting base frame 100. Under the drive of the drive motor 504, the drive shaft 503 drives the worm 502 to rotate, the worm 502 drives the worm gear 505 to rotate, and the worm gear 505 drives one of the winding rollers 500 to rotate, thereby providing power to the winding module.

[0054] The first detachable component includes a mounting slot 304 located on the outside of the take-up roller 500. Curtain mounting blocks 305 are symmetrically arranged on both sides of the upper end of the curtain panel 300. A curtain pin 307 is slidably disposed in each curtain mounting block 305. The outer end of the curtain pin 307 is connected to the curtain mounting block 305 via a mounting spring 306. The inner wall of the mounting slot 304 is provided with a mating socket for easy insertion of the curtain pin 307. When connecting the take-up roller 500 and the curtain panel 300, the curtain mounting block 305 is first connected to the mounting slot 304, and then the curtain pin 307 is inserted into the mating socket using the mounting spring 306, achieving modular and rapid connection and facilitating subsequent maintenance.

[0055] Working principle: In actual use, the mounting base frame 100 is installed on the top of the wall, then the guide rails 301 are installed on both sides of the wall. The upper end of the curtain panel 300 is connected to the take-up roller 500, and then the curtain panel 300 is installed and fixed to the curtain panel seat 600. The two sides of the curtain panel 300 are matched with the track module. When the take-up drive component is working, when the take-up roller 500 rotates, the take-up roller 500 will drive the first transmission wheel 506 to rotate. The first transmission wheel 506 drives the second transmission wheel 509 to rotate through the first transmission belt 507. The second transmission wheel 509 is connected to the first transmission belt 507. The first drive shaft 510 drives the third drive wheel 511 to rotate, and the third drive wheel 511 drives the fourth drive wheel 512 to rotate through the second drive belt 513. The fourth drive wheel 512 drives the transmission roller 409 to rotate. When the curtain 300 is lowered, the take-up roller 500 drives the first drive wheel 506 to rotate, thereby driving the transmission belt 403 to rotate. This allows the items placed on the transmission belt 403 to be transferred away. This transfer can transfer both small particulate impurities and large volume impurities at the same time, eliminating the drawbacks of the existing technology.

[0056] When the curtain panel seat 600 moves down, under the guidance of the guide table 521, the locking table 524 will smoothly pass through the locking table groove 605. Under the action of the inclined surface at the end of the locking slider 523, the locking slider 523 will be retracted into the locking table 524. Then, under the action of the locking spring 520, the locking slider 523 will pop out, completing the locking of the curtain panel seat 600.

[0057] When the second transmission wheel 509 rotates, the unlocking umbrella block 508 is driven by the unlocking umbrella block 508, which in turn drives the unlocking wheel 517 to rotate. The unlocking wheel 517 rotates through the linkage pin 518, and the linkage pin 518 drives the locking slider 523 to be retracted into the locking table 524 through the unlocking linkage rod 519, thus completing the unlocking. Here, because the transmission circumference of the unlocking umbrella block 508 is limited, it will not drive the unlocking linkage rod 519 to rotate excessively, and there will be no interference problem. The locking method here is mechanical locking, which ensures the reliability of isolation.

[0058] In addition, the smoke removal module and sprinkler module improve the product's isolation effect and further increase the probability of escape.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
