Description

Technical Field

[0001] The invention relates to the technical field of rolling shutter doors, and in particular to a rolling door structure for an underground garage. Background Art

[0002] The underground garage rolling door is an automated door specially used for the entrance of underground parking lots. It is usually installed at the entrance and exit of the garage to control the entry and exit of vehicles. Its main functions are to provide security protection, convenient passage, environmental isolation, and fire protection, waterproofing, anti-theft protection and other protections in certain circumstances. The underground garage rolling door needs to be opened and closed frequently in daily use, so the design requires both durability and reliability, and a high level of automation to facilitate user operation.

[0003] The patent with the publication number of CN106088999A discloses an underground garage rolling door, including a rolling door body arranged on the door entrance, the rolling door body including a curtain piece; electromagnetic suction plates fixed to the wall are respectively arranged on the left and right sides of the curtain piece, guide blocks are respectively arranged on the top and bottom of the left and right sides of the curtain piece, and an extrusion plate which can be adsorbed by the electromagnetic suction plate is also arranged between the upper and lower guide blocks located on the same side; the curtain piece is located between the extrusion plate and the electromagnetic suction plate; a second electromagnetic suction plate and a second extrusion plate are also arranged in the ground below the rolling door body, the two sides of the second extrusion plate are respectively longitudinally arranged by supporting guides, and the second extrusion plate can slide along the supporting guides, the second electromagnetic suction plate and the second extrusion plate are arranged opposite to each other with a spacing, and the lower end of the curtain piece can be placed in the gap between the second electromagnetic suction plate and the second extrusion plate.

[0004] The prior art has the following defects:

[0005] Unable to achieve automatic touch anti-pinch: Existing rolling doors are generally equipped with anti-pinch sensors, which can automatically stop or reverse when an obstacle is detected to prevent harm to people and objects. However, the sensing of anti-pinch sensors is limited, and in emergencies such as earthquakes, fires, etc., rolling doors cannot detect obstacles and stop or reverse in time, which may delay escape time or hinder emergency rescue, causing greater harm or loss. Therefore, it is necessary to set up a device that realizes automatic touch anti-pinch function to protect the safety of people and objects in emergencies or insensitive sensing.

[0006] Unable to automatically sense floods and form flood gates: In the event of heavy rain, typhoons or urban waterlogging, underground garages can easily become the main intrusion point for water accumulation due to their low terrain. If the rolling door cannot automatically sense floods and form flood gates in time, the flood will directly flow into the garage, which may cause the vehicles in the garage to be flooded and cause significant property losses. Therefore, it is necessary to set up a device that automatically senses floods and forms flood gates to protect personal and property safety. Summary of the invention

[0007] In view of the problems in the prior art, such as the inability to achieve automatic touch anti-pinch and the inability to automatically sense floods and form flood control gates, an underground garage rolling door structure is proposed.

[0008] The present application provides an underground garage rolling door structure, the purpose of which is to protect the safety of people and objects in emergencies or when the sensing function is not sensitive by setting a device that realizes the automatic touch anti-pinch function, and to protect the safety of people and property by setting a device that automatically senses floods and forms flood control gates.

[0009] The technical solution of the present invention is: an underground garage rolling door structure, comprising a fixing frame, a reel device arranged on the top of the fixing frame, a motor device arranged on one side of the reel device, a rolling door assembly arranged at the bottom of the reel device, and a water-blocking and anti-pinch mechanism arranged at the bottom of the rolling door assembly, wherein the water-blocking and anti-pinch mechanism comprises a flood gate arranged at the bottom of the rolling door assembly, wherein an emergency stop assembly and an anti-pinch assembly are arranged inside the flood gate;

[0010] The anti-pinch assembly includes a slide groove and a swing groove opened on the inner wall of the flood control gate, the inner wall of the slide groove is slidably connected with a slider, the bottom of the slider is fixedly connected with a rubber sealing strip, the inner wall of the swing groove is movably connected with an eccentric block, and one end of the eccentric block in the swing groove overlaps with the top of the slider.

[0011] By adopting the above scheme, through the anti-pinch component, when the rolling door falls, when a foreign object appears under the rolling door assembly and is not detected by the sensor or the sensor fails in an emergency, the rubber sealing strip at the bottom of the flood control gate first contacts the foreign object, and the rubber sealing strip is forced to shrink toward the inside of the flood control gate. The slider at the top of the rubber sealing strip squeezes the eccentric block in the slide groove and slides in the swing groove, so that the flood control gate is stuck and stops sliding down, avoiding damage to the foreign object.

[0012] Furthermore, the emergency stop assembly includes a rotation shaft and a torsion spring rotatably connected to the inner wall of the flood control gate, the torsion spring is arranged on the outside of the rotation shaft, the outer wall of the rotation shaft is fixedly connected with a pressure block and a positioning block, the inner wall of the pressure block is fixedly connected to one end of the torsion spring, and the other end of the torsion spring is fixedly connected to the inner wall of the flood control gate.

[0013] By adopting the above scheme, through the setting of the emergency stop assembly, when the rolling door assembly continues to fall, the bottom of the rolling door assembly contacts and squeezes the pressure block, the pressure block rotates on the rotation shaft, and drives the positioning block to rotate, so that the rolling door assembly is blocked and stops sliding down, and rises through the abnormal force sensing, and the rotation shaft is also reset by the torsion spring unloading force.

[0014] Furthermore, the inner wall of the fixing frame is provided with a lifting slot, a clamping slot and a limiting slot, the inner wall of the clamping slot is overlapped with the other end of the eccentric block and the outer wall of the clamping block respectively, and the inner wall of the limiting slot is slidably connected with the outer wall of the rotating shaft.

[0015] By adopting the above scheme, the eccentric block contacts the card slot and is stuck, so that the flood control gate can stop sliding down to avoid harm to foreign objects. The locking block is turned to be stuck in the card slot, so that the rolling door assembly is blocked and stops sliding down.

[0016] Furthermore, the rolling door assembly includes a rolling door curtain piece slidably connected to the inner wall of the lifting slot, and the rolling door curtain piece is rolled into the interior of the reel device when rising, and a clamping assembly is arranged inside the rolling door curtain piece.

[0017] Furthermore, the clamping assembly includes a bidirectional rotating shaft and a transmission shaft rotatably connected to the inner wall of the rolling door curtain piece, the outer wall of the bidirectional rotating shaft is provided with left-handed thread and right-handed thread, and the inner walls of the left-handed thread and the right-handed thread are both threadedly connected with a clamping block.

[0018] Furthermore, a transmission gear is fixedly connected to the outer wall of the transmission shaft, the teeth of the transmission gear are meshed with the teeth of the bidirectional rotating shaft, and a rotation key groove is opened on the inner wall of the transmission shaft.

[0019] By adopting the above scheme, through the setting of the rolling door assembly, the key is inserted into the rotating key slot and twisted, or the transmission shaft is controlled to rotate by remote control, and the two-way rotating shaft is driven to rotate by the transmission gear, so that the two clamping blocks are retracted into the rolling door curtain piece under the rotation of the left-handed thread and the right-handed thread, the connection between the rolling door curtain piece and the flood control gate is released, and then the rolling door curtain piece is controlled to rise, providing convenience for pedestrians to pass.

[0020] Furthermore, the outer wall of the snap-in block is slidably connected to a snap-in sliding groove opened on the inner wall of the flood control gate, the outer wall of the rotating key slot is provided with an elliptical opening groove opened on the inner wall of the flood control gate, and the outer wall of the flood control gate is fixedly connected to a manual operation window, and the manual operation window is provided on the outside of the snap-in sliding groove and the elliptical opening groove.

[0021] By adopting the above scheme, the manual operation window is opened, and a key is inserted into the rotating key slot in the elliptical opening slot. When the rolling door curtain piece falls, the internal clamping block can slide in the clamping sliding slot.

[0022] Furthermore, the flood gate includes a protective shell slidably connected to the outer wall of the fixing frame, the inner wall of the protective shell is provided with a water tank, and the inner wall of the water tank is provided with a plurality of drainage holes.

[0023] Furthermore, a water inlet groove connected to the water tank is formed on the outer wall of the protective shell, and a filter plate is fixedly connected between the inner wall of the water inlet groove and the inner wall of the water tank.

[0024] By adopting the above scheme, through the flood control gate set up, when the water flow has not passed the bottom line of the water inlet trough, the rolling door curtain is normally opened. When the water flow exceeds the bottom line of the water inlet trough, the water flows into the water storage tank through the water inlet trough and accumulates in the water storage tank, which increases the gravity of the flood control gate. At this time, the rolling door curtain senses the increased bottom gravity so that it cannot be opened, thereby blocking the accumulation of water, and the water in the water storage tank will be discharged from the drainage hole to the sewer. As the amount of accumulated water decreases, the bottom gravity is sensed in real time to cause the rolling door curtain to open again.

[0025] Beneficial effects of the present invention:

[0026] 1. Through the anti-pinch component, when the rolling door falls, when there is a foreign object under the rolling door component that is not detected by the sensor or the sensor fails in an emergency, the rubber sealing strip at the bottom of the flood gate will first contact the foreign object, and the rubber sealing strip will be forced to shrink toward the inside of the flood gate. The slider at the top of the rubber sealing strip squeezes the eccentric block in the slide groove and slides in the swing groove, so that the flood gate is stuck and stops sliding, avoiding damage to the foreign object.

[0027] 2. When the rolling door curtain falls, the internal clamping block slides in the clamping sliding groove, so that the bottom of the rolling door curtain contacts and squeezes the pressure block. The pressure block rotates on the rotation shaft and drives the clamping block to rotate into the clamping groove, so that the rolling door curtain is blocked and stops sliding down, and it rises through abnormal force sensing. The rotation shaft also resets through the torsion spring unloading force. The door curtain drives the flood control gate to rise through the clamping block, so that the eccentric block swings first and then slides in the swing groove. When the slider slides down in the slide groove, the eccentric block is reset by gravity, and the rubber sealing strip is finally separated from the foreign matter, so that the foreign matter is never subjected to the pressure of the rolling door curtain, thereby achieving the effect of protecting the safety of foreign matter in emergencies or insensitive sensing.

[0028] 3. Open the manual operation window, insert the key into the elliptical opening slot and twist it, or remotely control the transmission shaft to rotate, and the transmission gear drives the two-way shaft to rotate, so that the two clamping blocks are retracted into the rolling door curtain under the rotation of the left-handed thread and the right-handed thread, and the rolling door curtain and the flood control gate are disconnected, and then the rolling door curtain is controlled to rise, providing convenience for pedestrians.

DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0043] Example 1, reference Figure 1 - Fig. 9, which is the first embodiment of the present invention, provides an underground garage rolling door structure, including a fixed frame 1, a reel device 2 arranged on the top of the fixed frame 1, a motor device 3 arranged on one side of the reel device 2, a rolling door assembly 4 arranged at the bottom of the reel device 2, and a water-blocking and anti-pinch mechanism 5 arranged at the bottom of the rolling door assembly 4, the water-blocking and anti-pinch mechanism 5 includes a flood gate 51 arranged at the bottom of the rolling door assembly 4, and an emergency stop assembly 52 and an anti-pinch assembly 54 are arranged inside the flood gate 51.

[0044] Reference Figure 5 - Fig. 9 The anti-pinch assembly 54 includes a slide groove 543 and a swing groove 545 opened on the inner wall of the flood control gate 51. The inner wall of the slide groove 543 is slidably connected with a slider 542. The bottom of the slider 542 is fixedly connected with a rubber sealing strip 541. The inner wall of the swing groove 545 is movably connected with an eccentric block 544. One end of the eccentric block 544 in the swing groove 545 overlaps with the top of the slider 542.

[0045] Specifically, the motor device 3 controls the rolling door assembly 4 to reel in and out the reel device 2. The rolling door assembly 4 is detachably connected to the water-blocking and anti-pinch mechanism 5. The water-blocking and anti-pinch mechanism 5 is composed of a flood gate 51 and a rubber sealing strip 541 at the bottom. When the rubber sealing strip 541 rises, it will drive the eccentric block 544 to move, thereby restricting and jamming the flood gate 51.

[0046] By setting the anti-pinch component 54, when the rolling door falls, when a foreign object appears under the rolling door component 4 and is not detected by the sensor or the sensor fails in an emergency, the rubber sealing strip 541 at the bottom of the flood gate 51 first contacts the foreign object, and the rubber sealing strip 541 is forced to shrink toward the inside of the flood gate 51, and the slider 542 at the top of the rubber sealing strip 541 squeezes the eccentric block 544 in the slide groove 543 to slide in the swing groove 545, so that the flood gate 51 is stuck and stops sliding down, avoiding damage to the foreign object.

[0047] Reference Figure 5 - Fig. 9 The emergency stop assembly 52 includes a rotation shaft 521 and a torsion spring 522 which are rotatably connected to the inner wall of the flood control gate 51. The torsion spring 522 is arranged on the outer side of the rotation shaft 521. The outer wall of the rotation shaft 521 is fixedly connected with a pressure block 523 and a positioning block 524. The inner wall of the pressure block 523 is fixedly connected to one end of the torsion spring 522, and the other end of the torsion spring 522 is fixedly connected to the inner wall of the flood control gate 51.

[0048] Specifically, the two ends of the torsion spring 522 are respectively connected to the pressure block 523 and the flood control gate 51, so that the rotation shaft 521 can rotate and reset when the force is unloaded, and at the same time, the pressure block 523 can drive the positioning block 524 to rotate through the rotation shaft 521 when the force is applied.

[0049] By means of the emergency stop assembly 52, when the rolling door assembly 4 continues to fall, the bottom of the rolling door assembly 4 contacts and squeezes the pressure block 523, and the pressure block 523 rotates on the rotation shaft 521, and drives the positioning block 524 to rotate, so that the rolling door assembly 4 is blocked and stops sliding down, and is caused to rise by sensing abnormal force, and the rotation shaft 521 is also reset by unloading the force through the torsion spring 522.

[0050] Reference Figure 7 - Fig. 9 The inner wall of the fixing frame 1 is provided with a lifting groove 11, a clamping groove 12 and a limiting groove 13. The inner wall of the clamping groove 12 is overlapped with the other end of the eccentric block 544 and the outer wall of the clamping block 524 respectively, and the inner wall of the limiting groove 13 is slidably connected with the outer wall of the rotating shaft 521.

[0051] By the eccentric block 544 contacting the card slot 12 and being stuck, the flood control gate 51 can stop sliding down to avoid damage to foreign objects. By the blocking block 524 turning to be stuck in the card slot 12, the rolling door assembly 4 can be blocked and stopped from sliding down.

[0052] Reference Figure 4 The rolling door assembly 4 includes a rolling door curtain piece 41 which is slidably connected to the inner wall of the lifting groove 11. When the rolling door curtain piece 41 rises, it is rolled into the interior of the reel device 2. A clamping assembly 42 is arranged inside the rolling door curtain piece 41. The clamping assembly 42 includes a two-way rotating shaft 423 and a transmission shaft 426 which are rotatably connected to the inner wall of the rolling door curtain piece 41. A left-handed thread 422 and a right-handed thread 424 are provided on the outer wall of the two-way rotating shaft 423. The inner walls of the left-handed thread 422 and the right-handed thread 424 are both threadedly connected with a clamping block 421. A transmission gear 425 is fixedly connected to the outer wall of the transmission shaft 426. The teeth of the transmission gear 425 are meshed with the teeth of the two-way rotating shaft 423. A rotating key slot 427 is provided on the inner wall of the transmission shaft 426.

[0053] Specifically, a left-handed thread 422 and a right-handed thread 424 are provided on the bidirectional rotating shaft 423, and the two clamping blocks 421 move oppositely on the bidirectional rotating shaft 423. The bidirectional rotating shaft 423 is controlled to rotate by a transmission gear 425 on a transmission shaft 426. The transmission shaft 426 can be controlled by remote control or by inserting a key into a rotation key slot 427.

[0054] By means of the roller door assembly 4, a key is inserted into the rotating key slot 427 and twisted, or the transmission shaft 426 is controlled to rotate by remote control, and the bidirectional rotating shaft 423 is driven to rotate via the transmission gear 425, so that the two clamping blocks 421 are retracted into the roller door curtain piece 41 under the rotation of the left-handed thread 422 and the right-handed thread 424, and the roller door curtain piece 41 and the flood control gate 51 are disconnected, and then the roller door curtain piece 41 is controlled to rise, providing convenience for pedestrians to pass.

[0055] Reference Figure 5The outer wall of the snap-in block 421 is slidably connected to a snap-in sliding groove 55 opened on the inner wall of the flood control gate 51, the outer wall of the rotating key slot 427 is provided with an elliptical opening groove 56 opened on the inner wall of the flood control gate 51, and the outer wall of the flood control gate 51 is fixedly connected to a manual operation window 53, which is provided on the outside of the snap-in sliding groove 55 and the elliptical opening groove 56.

[0056] Specifically, the snap-fit ​​block 421 slides in the snap-fit ​​sliding groove 55, so that the rolling door curtain piece 41 can drive the flood control gate 51 to rise or fall, the elliptical opening groove 56 is used for inserting the key during manual operation, and the manual operation window 53 is used as an operation window during manual operation.

[0057] By opening the manual operation window 53 and inserting a key into the elliptical opening slot 56 to rotate the key slot 427 , when the rolling door curtain piece 41 falls, the internal clamping block 421 can slide in the clamping sliding slot 55 .

[0058] During use, the sensor intelligently senses the vehicle opening the rolling door, the motor device 3 runs to roll the rolling door curtain piece 41 into the reel device 2 in the lifting groove 11, and the lightweight flood gate 51 is raised through the connection of the clamping assembly 42, providing convenience for vehicles to enter and exit. When the rolling door falls, if there is a foreign object under the rolling door curtain piece 41 that is not detected by the sensor or the sensor fails in an emergency, the rubber sealing strip 541 at the bottom of the flood gate 51 first contacts the foreign object, and the rubber sealing strip 541 is forced to move toward the flood gate 51. The sliding block 542 on the top of the rubber sealing strip 541 squeezes the eccentric block 544 in the sliding groove 543 to slide in the swinging groove 545 and contact the card slot 12 to be stuck, so that the flood control gate 51 stops sliding down to avoid harm to foreign objects. The rolling door curtain piece 41 continues to fall, and the internal clamping block 421 slides in the clamping sliding groove 55, so that the bottom of the rolling door curtain piece 41 contacts and squeezes the pressure block 523. The pressure block 523 rotates on the rotation shaft 521 and drives the clamping block 524 to rotate and be inserted into the card slot 12, so that the rolling door curtain piece 41 is blocked and stops sliding down, and is sensed to rise by abnormal force. The rotating shaft 521 is also reset by unloading force through the torsion spring 522. The rolling door curtain piece 41 drives the flood control gate 51 to rise through the clamping block 421, so that the eccentric block 544 first swings and then slides in the swing groove 545. When the slider 542 slides down in the slide groove 543, the eccentric block 544 is reset by gravity, and the rubber sealing strip 541 is finally separated from the foreign matter, so that the foreign matter is never subjected to the pressure of the rolling door curtain piece 41, thereby protecting the safety of foreign matter in the event of an emergency or insensitive sensing. When the amount of accumulated water remains high and the rolling door curtain 41 needs to be opened, the manual operation window 53 is opened, and the key slot 427 is inserted into the elliptical opening slot 56 and twisted, or the transmission shaft 426 is controlled by remote control to rotate, and the two-way rotating shaft 423 is driven to rotate through the transmission gear 425, so that the two clamping blocks 421 are retracted into the rolling door curtain 41 under the rotation of the left-handed thread 422 and the right-handed thread 424, and the rolling door curtain 41 and the flood control gate 51 are disconnected, and then the rolling door curtain 41 is controlled to rise, providing convenience for pedestrians to pass.

[0059] Example 2, reference Fig.10 - Fig.11 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: Fig.10 The flood gate 51 includes a protective shell 511 slidably connected to the outer wall of the fixed frame 1, a water tank 512 is provided on the inner wall of the protective shell 511, a plurality of drainage holes 513 are provided on the inner wall of the water tank 512, a water inlet groove 514 connected to the water tank 512 is provided on the outer wall of the protective shell 511, and a filter plate 515 is fixedly connected between the inner wall of the water inlet groove 514 and the inner wall of the water tank 512.

[0060] Specifically, the flood gate 51 is composed of a lightweight protective shell 511, which has an anti-collision function. When the water tank 512 does not store water, the flood gate 51 is relatively light and can be driven to rise or fall by the rolling door curtain 41. When water is stored in the water tank 512, the gravity of the flood gate 51 increases and it cannot rise.

[0061] Through the set flood control gate 51, when the water flow has not passed the bottom line of the water inlet trough 514, the rolling door curtain 41 opens normally. When the water flow submerges the bottom line of the water inlet trough 514, the water flows into the water storage tank 512 through the water inlet trough 514 and accumulates in the water storage tank 512, which increases the gravity of the flood control gate 51. At this time, the rolling door curtain 41 senses the increased bottom gravity so that it cannot be opened, thereby blocking the accumulation of water, and the water in the water storage tank 512 will be discharged from the drainage hole 513 to the sewer. As the amount of accumulated water decreases, the bottom gravity is sensed in real time to open the rolling door curtain 41 again.

[0062] During use, when there is a rainstorm, typhoon or urban waterlogging, water flows to the low-lying underground garage. When the water does not pass the bottom line of the water inlet trough 514, the rolling door curtain 41 opens normally. When the water does not pass the bottom line of the water inlet trough 514, the water flows through the water inlet trough 514 into the water storage tank 512 and accumulates in the water storage tank 512, increasing the gravity of the flood control gate 51. At this time, the rolling door curtain 41 is unable to open through the increased gravity at the bottom, playing a role in blocking the accumulated water, and the water in the water storage tank 512 will be discharged from the drainage hole 513 to the sewer. As the amount of accumulated water decreases, the bottom gravity is sensed in real time to open the rolling door curtain 41 again. The rest of the structure is the same as that of Example 1.

[0063] Working principle of the present invention:

[0064] Initially, the rolling door is in a closed state. The sensor intelligently senses the vehicle to open the rolling door. The motor device 3 runs to roll the rolling door curtain 41 into the reel device 2 in the lifting groove 11. Through the connection of the clamping component 42, the lightweight flood control gate 51 rises accordingly, providing convenience for vehicles to enter and exit.

[0065] When the rolling door falls, when a foreign object appears under the rolling door curtain 41 and is not detected by the sensor or the sensor fails in an emergency, the rubber sealing strip 541 at the bottom of the flood control gate 51 first contacts the foreign object, and the rubber sealing strip 541 is forced to shrink toward the inside of the flood control gate 51. The slider 542 at the top of the rubber sealing strip 541 squeezes the eccentric block 544 in the slide groove 543 to slide in the swing groove 545, and contacts the card slot 12 and is stuck, so that the flood control gate 51 stops sliding down to avoid damage to the foreign object.

[0066] The rolling door curtain piece 41 continues to fall, and the internal engaging block 421 thereof slides in the engaging sliding groove 55, so that the bottom of the rolling door curtain piece 41 contacts and presses the pressure block 523, and the pressure block 523 rotates on the rotation shaft 521, and drives the engaging block 524 to rotate and engage in the engaging groove 12, so that the rolling door curtain piece 41 is blocked and stops sliding down, and is caused to rise by sensing the abnormal force, and the rotation shaft 521 is also reset by unloading the force through the torsion spring 522.

[0067] The rolling door curtain piece 41 drives the flood control gate 51 to rise through the clamping block 421, so that the eccentric block 544 first swings and then slides in the swing groove 545. When the slider 542 slides down in the slide groove 543, the eccentric block 544 is reset by gravity, and the rubber sealing strip 541 is finally separated from the foreign object, so that the foreign object is never subjected to the pressure of the rolling door curtain piece 41, thereby achieving the effect of protecting the safety of foreign objects in emergencies or insensitive sensing.

[0068] When heavy rain, typhoon or urban waterlogging occurs, water flows to the low-lying underground garage. When the water does not pass the bottom line of the water inlet trough 514, the rolling door curtain 41 opens normally. When the water submerges the bottom line of the water inlet trough 514, the water flows into the water storage tank 512 through the water inlet trough 514 and accumulates in the water storage tank 512, increasing the gravity of the flood control gate 51. At this time, the rolling door curtain 41 senses the increased bottom gravity so that it cannot be opened, thereby blocking the accumulated water. The water in the water storage tank 512 will be discharged to the sewer from the drainage hole 513. As the amount of accumulated water decreases, the bottom gravity is sensed in real time to open the rolling door curtain 41 again.

[0069] When the amount of accumulated water remains high and the rolling door curtain 41 needs to be opened, the manual operation window 53 is opened, and the key slot 427 is inserted into the elliptical opening slot 56 and twisted, or the transmission shaft 426 is remotely controlled to rotate, and the two-way rotating shaft 423 is driven to rotate through the transmission gear 425, so that the two clamping blocks 421 are retracted into the rolling door curtain 41 under the rotation of the left-handed thread 422 and the right-handed thread 424, and the rolling door curtain 41 and the flood control gate 51 are disconnected, and then the rolling door curtain 41 is controlled to rise, providing convenience for pedestrians to pass.
