A drive type roller shutter door ventilation structure

Abstract

The application discloses a driving type rolling shutter door ventilation structure, which comprises a side rail plate, a driving box body, a fireproof rolling shutter, a ventilation assembly and a power motor. When a fire occurs, the power motor drives a translation rod to move, so that the translation rod moves from one side to the middle part of the fireproof rolling shutter. At this time, the translation rod drives a plurality of floating columns and blocking blocks to move to the inner end, and the blocking blocks are separated from the ventilation holes, so that the ventilation holes are ventilated. In this way, the inside and outside of the fireproof rolling shutter are ventilated, and the risk of overturning caused by negative pressure is prevented. The application is automatically sensed by a plurality of pressure sensors which are uniformly arranged from top to bottom on the fireproof rolling shutter. When the inside pressure is detected to be too large, a signal is sent to a controller. The controller sends a signal to the power motor, so that real-time detection and monitoring are realized.

Description

Technical Field

[0001] This invention belongs to the field of fireproof rolling shutter door manufacturing, and particularly relates to a ventilation structure for a drive-type rolling shutter door. Background Technology

[0002] Currently, most fire-resistant roller shutters designed for special needs possess fire-resistant properties. Fire-resistant roller shutters are indispensable fire protection facilities in modern high-rise buildings. In addition to the functions of ordinary doors, fire-resistant roller shutters have special functions such as fire prevention, smoke isolation, suppression of fire spread, and protection of personnel evacuation. Existing fire-resistant roller shutters rely on sealing for fire protection. However, in the event of a fire, the negative pressure created in the fire area can easily overturn the entire fire-resistant roller shutter, rendering it ineffective and allowing the fire to spread easily. Therefore, it is necessary to improve the ventilation of fire-resistant roller shutters during special times, which requires structural upgrades to traditional fire-resistant roller shutters. Summary of the Invention

[0003] To address the shortcomings of the existing technology, the present invention provides a ventilation structure for a drive-type roller shutter door that facilitates ventilation and prevents negative pressure from causing it to tip over.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A ventilation structure for a driven roller shutter door includes side track plates, a drive housing, a fireproof roller shutter, a ventilation component, and a power motor. The fireproof roller shutter is connected to the lower side of the drive housing. A side track plate is installed on each side of the drive housing. The fireproof roller shutter is slidably installed on both sides within the side track plates. The ventilation component is installed inside the fireproof roller shutter. The ventilation component includes a sliding rod, a floating column, a sleeve spring, an opening and closing block, a connecting rod, and a blocking block. The fireproof roller shutter has multiple insertion holes evenly spaced from top to bottom, with ventilation holes on both sides of each insertion hole. The insertion holes are respectively... A floating column is inserted; the outer end of the floating column is connected to an opening and closing block; a sleeve spring is sleeved on the floating column, and the two ends of the sleeve spring press against the fireproof roller shutter and the opening and closing block; a connecting rod is installed on the inner end of the floating column; a blocking block is connected to each end of the connecting rod; the blocking block is inserted into the vent hole; a translation rod is installed on one side of the fireproof roller shutter; a power motor is installed in the middle of the outside of the drive box, the power motor drives the translation rod to move, the translation rod drives multiple floating columns and blocking blocks to move inward, and causes the blocking blocks to disengage from the vent hole, so that the vent hole can be ventilated.

[0005] Furthermore, multiple pressing blocks are evenly installed on the inner side of the translation rod from top to bottom; each pressing block corresponds to a one-to-one opening and closing block; the translation rod moves and drives the pressing blocks to press against the opening and closing blocks, so that the opening and closing blocks drive the floating column to move inward.

[0006] Furthermore, both the pressing block and the opening / closing block have a wedge-shaped structure.

[0007] Furthermore, the fireproof roller shutter is evenly equipped with multiple pressure sensors from top to bottom; a controller is provided on the outside of the drive housing; the controller signals and connects the pressure sensors and the power motor.

[0008] Furthermore, it also includes a transmission mechanism; the transmission mechanism includes a drive gear, a sliding plate, and a locking block; the upper end of the translation rod is connected to the sliding plate; the lower side of the sliding plate is connected to the locking block, which is slidably engaged with the side of the drive housing; the end of the power motor is connected to the drive gear for forward and reverse rotation control; the lower side of the drive gear is engaged with the upper side of the sliding plate.

[0009] Furthermore, a positioning strip is provided on the outer side of the drive housing; a strip-shaped slot is provided on the upper side of the positioning strip; the locking block is slidably engaged with the strip-shaped slot.

[0010] Furthermore, both the floating column and the insertion hole have rectangular cross-sections.

[0011] The beneficial effects of this invention are as follows: In the event of a fire, this invention uses a motor to drive a sliding rod, moving it from one side to the middle of the fireproof roller shutter. This sliding rod then drives multiple floating columns and blocking blocks to move inwards, disengaging the blocking blocks from the vents and allowing ventilation. This ensures ventilation both inside and outside the fireproof roller shutter, preventing the risk of it tipping over due to negative pressure. Furthermore, this invention utilizes multiple pressure sensors evenly installed from top to bottom on the fireproof roller shutter for automatic sensing. When excessive internal pressure is detected, a signal is sent to the controller, which then sends a signal to the motor, thus achieving real-time detection and monitoring.

[0019] The invention will now be described in further detail with reference to the accompanying drawings.

[0020] like Figures 1 to 7 As shown, a ventilation structure for a driven roller shutter door includes a side track plate 1, a drive housing 2, a fireproof roller shutter 3, a ventilation component 4, and a power motor 5. The lower side of the drive housing 2 is connected to the fireproof roller shutter 3. A side track plate 1 is installed on each side of the drive housing 2. The fireproof roller shutter 3 is slidably installed on both sides within the side track plate 1. The ventilation component 4 is installed inside the fireproof roller shutter 3. The ventilation component 4 includes a translation rod 41, a floating column 42, a sleeve spring 43, an opening and closing block 44, a connecting rod 45, and a blocking block 46. The fireproof roller shutter 3 has multiple insertion holes 31 evenly spaced from top to bottom, and ventilation holes 32 are opened on both sides of each insertion hole 31. A ventilation hole 32 is inserted into each insertion hole 31. A floating column 42 is provided; the outer end of the floating column 42 is connected to an opening and closing block 44; a sleeve spring 43 is sleeved on the floating column 42, and the two ends of the sleeve spring 43 press against the fireproof roller shutter 3 and the opening and closing block 44; a connecting rod 45 is installed on the inner end of the floating column 42; a blocking block 46 is connected to each end of the connecting rod 45; the blocking block 46 is inserted into the vent hole 32; a translation rod 41 is installed on one side of the fireproof roller shutter 3; a power motor 5 is installed in the middle of the outside of the drive box 2, the power motor 5 drives the translation rod 41 to move, the translation rod 41 drives multiple floating columns 42 and blocking blocks 46 to move inward, and causes the blocking blocks 46 to disengage from the vent hole 32, so that the vent hole 32 can be ventilated.

[0021] like Figures 1 to 7 As shown, in order to synchronously drive the translation rod 41 to multiple opening and closing blocks 44 and achieve synchronous opening and closing control of multiple blocking blocks 46, multiple pressing blocks 411 are evenly installed on the inner side of the translation rod 41 from top to bottom; each pressing block 411 corresponds to one opening and closing block 44; the translation rod 41 moves and drives the pressing blocks 411 to press against the opening and closing blocks 44, causing the opening and closing blocks 44 to drive the floating column 42 to move inward. Furthermore, both the pressing blocks 411 and the opening and closing blocks 44 have a wedge-shaped structure. This wedge-shaped structure achieves a sliding compression structure, facilitating power transmission.

[0022] like Figures 1 to 7As shown, in order to achieve automatic sensing control, the fireproof roller shutter 3 is further equipped with multiple pressure sensors 6 evenly installed from top to bottom; the drive housing 2 is equipped with a controller 7 on its exterior; the controller 7 is connected to the pressure sensors 6 and the power motor 5 via signal control.

[0023] like Figures 1 to 7 As shown, to facilitate the horizontal reciprocating drive of the translation rod 41 by the power motor 5, a transmission mechanism 8 is further included. The transmission mechanism 8 includes a drive gear 81, a sliding plate 82, and a locking block 83. The upper end of the translation rod 41 is connected to the sliding plate 82; the lower side of the sliding plate 82 is connected to the locking block 83, which is slidably engaged with the side of the drive housing 2. The end of the power motor 5 is connected to the drive gear 81 for forward and reverse rotation control; the lower side of the drive gear 81 is meshed with the upper side of the sliding plate 82. Furthermore, a positioning strip 21 is provided on the outer side of the drive housing 2; a strip-shaped groove 211 is provided on the upper side of the positioning strip 21; the locking block 83 is slidably engaged with the strip-shaped groove 211. More preferably, the cross-sections of the floating column 42 and the insertion hole 31 are both rectangular.

[0024] In the event of a fire, the present invention uses a power motor 5 to drive a translation rod 41 to move from one side to the middle of the fireproof roller shutter 3. At this time, the translation rod 41 drives multiple floating columns 42 and blocking blocks 46 to move inward. That is, the translation rod 41 presses against the opening and closing block 44, and the opening and closing block 44 drives the floating columns 42 and connecting rods 45 to move inward. The connecting rods 45 drive the blocking blocks 46 to move and disengage from the vent 32. In this way, the blocking blocks 46 disengage from the vent 32 and allow the vent 32 to ventilate. This allows ventilation to be obtained on both the inner and outer sides of the fireproof roller shutter 3, preventing the risk of overturning due to negative pressure. The present invention uses multiple pressure sensors 6 evenly installed from top to bottom on the fireproof roller shutter 3 for automatic sensing. When excessive pressure is detected on the inner side, a signal is sent to the controller 7, and the controller 7 sends a signal to the power motor 5, thus realizing real-time detection and monitoring. When ventilation is not required, the spring 43 presses against the opening and closing block 44 at the outer end, causing the blocking block 46 to close the ventilation hole 32.

[0025] 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.
