Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building fireproof roller shutter devices, and in particular to a trackless fireproof separation system. Background Art
[0002] Building fires are a frequent safety accident this year. When a fire occurs, the fire point spreads heat through heat conduction, heat convection and heat radiation, igniting the surrounding combustibles, accompanied by a large amount of smoke, heat and harmful gases, which spread in the building, posing a great threat to people's lives and property. The most effective measure to prevent the spread of building fires is to set up building fire separations to prevent the fire from spreading to adjacent areas within a certain period of time, creating opportunities for people to escape and fire rescue.

[0035] Example
[0036] This embodiment provides a specific implementation method of the trackless fire separation system. Figure 1 As shown, it includes a winding box 1, a fireproof motor 4, a motor transmission assembly 10, a reel 6, and a rolling curtain 8. The winding box 1 is used to be installed on a building. The fireproof motor 4 and the reel 6 are both installed in the winding box 1. The fireproof motor 4 is connected to the reel 6 through the motor transmission assembly 10. One end of the motor transmission assembly 10 is connected to the driving shaft of the fireproof motor 4, and the other end is connected to the reel. The reel 6 is configured to rotate under the drive of the motor transmission assembly 10. The rolling curtain 8 is wound on the reel 6, and a counterweight 9 is provided at the end of the rolling curtain 8. Under normal circumstances, the fire-proof motor 4 drives the reel 6 to rotate through the motor transmission assembly 10, and the rolling curtain 8 is stored in the winding box 1. When a fire occurs or the area needs to be isolated, the fire-proof motor 4 drives the motor transmission assembly 10 to drive the reel 6 to rotate, and the rolling curtain 8 is lowered. The counterweight 9 arranged at the end of the rolling curtain 8 can rely on its own counterweight 9 to assist the rolling curtain 8 in descending. At the same time, it can also keep the rolling curtain 8 from descending smoothly to avoid bending of the rolling curtain 8 during the descent.
[0037] In this embodiment, the sides of adjacent rolling blinds 8 are staggered and connected by magnetic attraction, and the adjacent rolling blinds 8 can be connected by magnetic attraction.
[0038] In this embodiment, magnets 13 are provided on the side of the rolling curtain 8, and adjacent rolling curtains 8 are connected together by attraction through the magnets 13. Adjacent rolling curtains 8 are arranged to overlap a portion, and the magnets 13 are arranged on the overlapping portion, so as to further increase the sealing between adjacent rolling curtains 8. Specifically, the magnets 13 are 13 pieces of neodymium iron boron magnets, and a plurality of them are arranged along the descending direction of the rolling curtain 8. The plurality of neodymium iron boron magnets 13 can be evenly distributed or unevenly distributed, as long as the staggered connection between two adjacent rolling curtains 8 can be achieved. The length of the neodymium iron boron magnet 13 is 100m, the width is 10mm, the thickness is 3mm, and the interval is 100mm. Ensure that the overlapping position fits tightly.
[0039] In this embodiment, the counterweight 9 includes a receiving tube and a lead bar. The receiving tube is connected to the end of the roller blind 8, and the lead bar is placed in the receiving tube. By placing the lead bar in the receiving tube, the size of the roller blind 8 can be reduced and the occupied space can be reduced. The number of lead bars in the receiving tube can be adjusted according to actual conditions so that the counterweight 9 can ensure the basic load-bearing capacity.
[0040] Specifically, the accommodation tube is a round tube with a radius of 17 mm and a wall thickness of 2 mm. As a replaceable embodiment, the accommodation tube can also be a galvanized square tube of 30 mm*30 mm*2 mm. An installation bag 12 is provided at the end of the roller blind 8. The accommodation tube with a lead bar is inserted into the installation bag 12 and mechanically fixed with bolts. The counterweight 9 is 20 kg / m to ensure that the lightweight roller blind 8 can descend by its own weight.
[0041] In this embodiment, a temperature control release device 17 is provided at the brake of the fireproof motor 4. The temperature control release device 17 is set to melt or burst the temperature control element when the preset temperature is reached, and the rolling curtain 8 is released by its own weight. Specifically, the brake of the fireproof motor 4 keeps the reel immobile under normal circumstances, so that the rolling curtain 8 remains wound on the reel to prevent the rolling curtain 8 from falling by its own weight; in the event of a fire, the temperature of the space will rise, and when the preset temperature is reached, the temperature control element of the temperature control release device 17 will melt or burst, contacting the rotation restriction of the reel. At this time, when the fireproof motor 4 is not started, the rolling curtain 8 can be directly lowered by the deadweight of the rolling curtain 8 and the counterweight 9 at the end.
[0042] Specifically, the temperature threshold of the temperature control release device 17 is set to 73° C. When the ambient temperature rises to 73° C., the temperature control element melts or bursts.
[0043] In this embodiment, an uninterruptible power supply 3 is also included. The uninterruptible power supply 3 is electrically connected to the brake of the fireproof motor 4 and is used to open the brake of the fireproof motor 4. In an emergency, the main circuit is cut off, and the uninterruptible power supply 3 can open the brake of the fireproof motor 4, so that the roller blind 8 can be lowered under the action of its own weight and the counterweight 9.
[0044] In this embodiment, a temperature sensor 14, a smoke sensor 15 and an audible and visual alarm 16 are also included. The temperature sensor 14, the smoke sensor 15 and the audible and visual alarm 16 are all installed on the front lower side of the winding box 1, and are used to detect the temperature, smoke concentration, sound, light and other information in the space respectively. If an abnormality is detected, an alarm is activated.
[0045] In this embodiment, it also includes a motor support frame 5 and a bearing support frame 7. The motor support frame 5 is installed in the winding box 1, and the motor support frame 5 is used to support the fireproof motor 4. The reel sleeve is arranged on the outside of the fireproof motor 4; the bearing support frame 7 is used to support the bearing, one end of the reel is connected to the fireproof motor 4 through the reel transmission assembly 11, and the other end is rotatably connected to the bearing support frame 7 through the reel transmission assembly 11. A bearing is provided between the bearing support frame 7 and the reel, and the bearing support frame 7 is used to support the reel by supporting the bearing.
[0046] In this embodiment, a PLC control system 2 is also included, and the output ends of the temperature sensor 14, the smoke sensor 15, and the sound and light alarm 16 are unidirectionally electrically connected to the input end of the PLC control system 2, and the output end of the PLC control system 2 is unidirectionally electrically connected to the input end of the sound and light alarm 16, the input end of the fire prevention motor 4, and the central control room. It is convenient for the PLC control system 2 to collect signals and make command controls. If the PLC control system 2 receives a smoke alarm signal, it uniformly controls multiple fire prevention motors 4 to achieve synchronous take-off and landing, and transmits the signal to the central control room to achieve the linkage of the fire protection system.
[0047] Working principle:
[0048] Under normal circumstances, the roller blind 8 is rolled up on the reel, and the brake control of the fire-proof motor 4 limits the rotation of the reel; when the ambient temperature rises to the preset temperature, the temperature control element of the temperature control release device 17 melts or bursts, releasing the brake of the fire-proof motor 4, no longer limiting the rotation of the reel, and the roller blind 8 descends by its own weight to complete the isolation of the space.
