Technical Field

[0001] The utility model relates to the technical field of cable channel fire prevention equipment design, in particular to an ultra-thin hot aerosol fire extinguishing device applied to a cable channel. Background Art

[0002] A cable tray is a structure used to support, protect and organize cables. It is usually made of metal or plastic, has beams and support columns, and can span across the ceiling or walls of a building. It is designed to provide a safe and reliable cable channel to transfer cables from one location to another. The main function of a cable tray is to support cables and keep them stable in position, effectively organize and protect cables, and ensure the stable operation of the power system.

[0003] At present, there are many cables inside the cable tray. The cables inside the cable tray may suffer from short circuit, local overheating and other faults due to overheating, which will cause the insulation material to decrease in resistance, lose insulation ability or even burn. The hot aerosol fire extinguishing device is a new type of fire extinguishing equipment. It realizes the fire extinguishing function by burning an aerosol generating agent to produce an aerosol fire extinguishing agent. It is very suitable for fires caused by circuit breaks. However, after searching, it was found that there is currently no good hot aerosol fire extinguishing device for the inside of the cable tray. Therefore, it is necessary for the applicant to design an ultra-thin hot aerosol fire extinguishing device for use in cable channels. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figures 1 to 8The invention discloses an ultra-thin hot aerosol fire extinguishing device for cable channel, comprising a device shell 1, which is fixed to the inner wall of the bridge frame 6, a sol generator 2 is installed inside the device shell 1, a sol 11 and a sensor control component 12 are arranged inside the sol generator 2, a top cover 3 is installed on the top of the device shell 1, a cylinder rod 8 is fixed on both sides of the device shell 1, a U-shaped rod 9 is slid inside the cylinder rod 8, a spring 10 is connected to the cylinder rod 8 at the bottom end of the U-shaped rod 9, and the U-shaped rod 9 is hung on the block of the top cover 3, and the insertion rod 7 at the bottom of the top cover 3 is inserted into the top rod hole of the device shell 1, and corresponding grooves are provided on the device shell 1 and the top cover 3, and the thermal nozzle 4 and the thermal wire 5 installed on the sol generator 2 pass through the groove, and the thermal wire 5 is attached to and fixed to the inner wall of the bridge frame 6.

[0029] Through the above structural design, when in use, the sol generator 2 is placed inside the device shell 1, and then the top cover 3 is covered. At this time, the insertion rod 7 is inserted into the top rod hole of the device shell 1 to form an initial positioning, and the thermal nozzle 4 and the thermal wire 5 pass through the groove formed by the top cover 3 and the device shell 1. Then the U-shaped rod 9 is pulled up and stuck on the block of the top cover 3. At this time, the spring 10 provides a pulling force to keep the top cover 3 in a stable position. After that, the device shell 1 is fixed to the inner wall of the bridge 6, and then the thermal wire 5 is fixed to the inner wall of the bridge 6, and the end cover of the bridge 6 is covered. When the cable inside the bridge 6 catches fire, the thermal wire 5 can be detected and the injection mechanism can be started through the sensor control component 12, and the sol 11 is sprayed to the fire area through the thermal nozzle 4. These aerosols 11 burn instantly at high temperatures, releasing a large amount of hot aerosols 11, rapidly raising the ambient temperature and forming a thermal concentration zone, diluting the oxygen around the fire source to a non-flammable concentration, thereby extinguishing the fire source and avoiding serious fires inside the passage. At the same time, the overall thickness of this case is relatively thin, and it is suitable for the interior of the bridge frame 6 with a small space, and it is worthy of popularization and use. It should be noted that the operating principle of the aerosol generator 2 is an existing technical means, which will not be described in detail here.

[0030] A nameplate 16 is provided at the center of the top of the device housing 1, and a circle of reflective strips 20 is provided around the nameplate 16 on the top of the device housing 1, a nailing block 15 is slidably connected to the thermal line 5, and the nailing block 15 is nailed to the inner wall of the bridge 6, and the nailing block 15 is used to keep the thermal line 5 in a straight state, angle iron plates 17 are welded on both sides of the device housing 1, and the angle iron plates 17 are connected to the inner wall of the bridge 6 by bolts, the two plug blocks 13 at the bottom of the top cover 3 are inserted into the top groove of the sol generator 2, and the two plug blocks 13 at the bottom of the thin sol generator 2 are also inserted into the internal groove of the device housing 1.

[0031] Through the above structural design, the installation is further optimized. During installation, the two plug blocks 13 at the bottom of the sol generator 2 are inserted into the internal grooves of the device housing 1, and after the top cover 3 is installed, the two plug blocks 13 at the bottom are inserted into the top grooves of the sol generator 2, and then the sol generator 2 can be effectively fixed in position. After that, the angle iron plate 17 and the nailing block 15 respectively fix the device housing 1 and the thermal wire 5, which is very convenient. The reflective strip 20 makes it easy to see the device in a poorly lit environment, so that the staff can quickly find it for disassembly and replacement during later maintenance. Finally, the nameplate 16 is in a prominent position for easy identification of the model, which is very practical.

[0032] The working environment temperature range of the sol generator 2 is -20℃ to +55℃, and the relative humidity of the working environment of the sol generator 2 is less than 95%. The inner walls of the device casing 1 and the top cover 3 are both provided with insulation boards 14, and the insulation boards 14 are made of flame-retardant material. The inner walls of the grooves of the device casing 1 and the top cover 3 are bonded with sealing gaskets 19, and the sealing gaskets 19 are made of flame-retardant rubber.

[0033] In order to further optimize the performance, the working environment temperature range of the sol generator 2 is -20°C to +55°C, so it can work normally in a larger temperature range, and the relative humidity of the working environment is less than 95% to avoid the influence of moisture on it. The insulation board 14 can insulate and keep warm in case of fire to avoid high-temperature damage. Finally, the sealing gasket 19 enhances the sealing effect of the groove to prevent dust from entering the interior.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
