[0021] Reference Figure 1-4The portable smoke arrester provided by the utility model comprises a main pipe 1, and a fixing ring 2 is arranged on both the left and right ends of the outer side of the main pipe 1; a fixing plate 3 is arranged on the upper and lower sides of the left end of the fixing ring 2; a branch pipe 5 is arranged on the front and rear ends of one side adjacent to the two main pipes 1; a plurality of auxiliary pipes 6 are evenly arranged from front to back at one end adjacent to the two main pipes 1; a plurality of spray components 7 are embedded and installed from top to bottom at the right end of the auxiliary pipe 6; a connecting pipe 8 is arranged on the outer side of the main pipe 1 at the upper end; a connecting pipe 8 is arranged on the connecting pipe A mounting pipe 9 is provided at the upper end of 8, and the upper and lower ends of the secondary pipe 6 located in the middle are tightly connected to the two main pipes 1, and the upper and lower ends of the secondary pipes 6 located on the front and rear sides are tightly connected to the branch pipe 5. In the rescue of fire fighting in residential buildings, a portable smoke barrier is placed at the entrance to achieve the effect of isolating smoke and heat, and effectively prevent the spread of smoke. When in use, it is pushed to the mounting pipe 9 and the connecting pipe 8 through an external pipe, and water is spread through the main pipe 1 and the secondary pipe 6, and finally sprayed out through the sprinkler assembly 7, which can cover a large area at the fire scene and prevent the thick smoke from spreading to the periphery to a limited extent.

[0022] The portable smoke arrester includes a main pipe, a fixing ring, a fixing plate, a branch pipe, a secondary pipe, a spray assembly, a connecting pipe and a mounting pipe. This structural design enables the smoke arrester to be stably placed at the entrance of the fire scene, effectively preventing the spread of smoke. By arranging the spray assembly in the main pipe and the secondary pipe, water can be evenly distributed throughout the smoke arrester. When water is sprayed from the spray assembly, water mist can be formed to effectively absorb and block smoke and reduce the impact of smoke on the surrounding environment.

[0023] Due to the design of the main duct and the auxiliary duct, the smoke arrester can cover a larger area and effectively prevent the thick smoke from spreading to the periphery. This helps to reduce the damage of the fire to the surrounding area and protect the safety of personnel.

[0024] Smoke arresters are designed with portability in mind, allowing them to be easily moved and placed at the entrance of a fire scene. This helps to quickly respond to fires and reduce the spread of smoke. The design of smoke arresters can also effectively isolate the transfer of heat and reduce the thermal impact of the fire on the surrounding environment.

[0025] To sum up, the portable smoke barrier provided by the utility model has the advantages of stable structure, good smoke barrier effect, large coverage area, strong portability and prevention of heat transfer. It can effectively prevent the spread of smoke at the fire scene, protect the safety of personnel and reduce the damage of the fire to the surrounding environment.

[0026] As a further implementation scheme of the above technical solution: Figure 1-3As shown, the spray assembly 7 includes a fixed pipe 701; a connecting rod 702 is provided at the inner right end of the fixed pipe 701; a baffle 703 is provided at the right end of the connecting rod 702; a blocking block 704, a fixed shaft 705, a spring 706 and a temperature tube 707 are provided on the inner side of the fixed pipe 701 in sequence. When in use, the air is installed at the position of the aisle corridor. When the temperature at this position is higher than a certain degree Celsius, the temperature tube 707 will burst, and the blocking block 704 is pushed to the right under the action of the spring 706, so that the water in the auxiliary pipe 6 is discharged through the right end of the fixed pipe 701 in the spray assembly 7, and the water flow is sprayed into the baffle 703 in the connecting rod 702. The water flow is blocked by the baffle 703 so that the water flow is scattered and the water flow diffusion effect is improved.

[0027] As a further implementation scheme of the above technical solution: Figure 1-2 As shown, a fixing screw 4 is embedded at the right end of the fixing plate 3, and the fixing screw 4 passes through the fixing plate 3. The fixing screw 4 is threadedly connected to the fixing plate 3. Before use, it can be assembled, and the spray assembly 7 is downwardly attached to the wall of the corridor as a whole. The fixing ring 2 with the fixing plate 3 is manually clamped in the main pipe 1 from bottom to top. At this time, the fixing plate 3 is in contact with the wall, and the screw is manually passed through the fixing plate 3 and the wall, so that the fixing plate 3 and the fixing ring 2 install the pipe in the wall.

[0028] The portable smoke arrester provided by the utility model realizes efficient smoke blocking and cooling effect at the fire scene through the design of its spray assembly. The spray assembly includes a temperature tube 707. When the temperature exceeds the set value, the temperature tube will burst, thereby activating the spray system. This design enables the smoke arrester to automatically start at the early stage of a fire and quickly respond to the fire situation without manual intervention.

[0029] After the temperature tube bursts, the spring 706 pushes the block 704 to move to the right, opening the water flow channel. This mechanical trigger mechanism ensures that the spray assembly can still work normally in the case of insufficient water pipe pressure or power failure.

[0030] The right end of the connecting rod 702 is provided with a baffle 703, and the water flow will be dispersed when it is sprayed onto the baffle, thereby increasing the diffusion effect of the water flow. This design helps to increase the coverage area of ​​the water mist and more effectively absorb and block smoke.

[0031] The design of the fixing plate 3 enables the smoke arrester to be conveniently fixed on the wall of the corridor. The connection between the fixing screws 4 and the wall ensures the stability of the smoke arrester in the event of a fire and prevents displacement due to vibration or water flow impact.

[0032] In summary, the portable smoke arrester provided by the utility model achieves efficient smoke blocking and cooling effects at the fire scene through its temperature sensing automatic activation, mechanical trigger mechanism, baffle design and convenient installation method. These design features enable the smoke arrester to respond quickly when a fire occurs, effectively prevent the spread of smoke, protect the safety of personnel, and reduce the damage of the fire to the surrounding environment.

[0033] As a further implementation scheme of the above technical solution: Figure 4 As shown, the left end of the connecting rod 702 is fixedly connected to the block 704, and the left end of the block 704 is fixedly connected to the fixed shaft 705. A spring 706 is arranged on the outer side of the fixed shaft 705, and the two sides of the spring 706 are respectively fixedly connected to the block 704 and the fixed shaft 705. The block 704 is arranged in a cone shape, and the block 704, the fixed shaft 705 and the connecting rod 702 are slidingly connected to the fixed tube 701. When the temperature tube 707 explodes, the spring 706 in the fixed shaft 705 pushes the block 704 to the right until the block 704 contacts the left end of the connecting rod 702, and the connecting rod 702 is fixed to the fixed tube 701. At this time, after the block 704 is separated from the space set by the fixed tube 701, water can be sprayed out from the secondary pipe 6.

[0034] As a further implementation scheme of the above technical solution: Figure 4 As shown, the inner side of the temperature tube 707 is set in a red state, and the temperature tube 707 is in contact with the blocking block 704, the connecting rod 702 and the fixed tube 701 respectively. Since the liquid inside the temperature tube 707 is in a red state, and the red temperature tube 707 set on the market, this color represents 68°C. When the temperature is higher than 68°C, the temperature tube 707 can explode by itself, which is convenient for subsequent use.

[0035] The left end of the connecting rod 702 is fixedly connected to the block 704, and the left end of the block 704 is fixedly connected to the fixed shaft 705, and the spring 706 is located outside the fixed shaft 705. This design ensures that after the temperature tube 707 explodes, the spring 706 can accurately push the block 704 toward the connecting rod 702, thereby opening the water flow channel. The conical design of the block 704 helps to ensure the sealing between it and the fixed tube 701, and prevents untriggered misoperation.

[0036] The inner side of the temperature tube 707 is in red, which represents that its bursting temperature is 68° C. The use of this color coding enables the user to intuitively understand the activation temperature of the spray assembly, which is convenient for selecting the appropriate product under specific circumstances.

[0037] The temperature tube 707 is in contact with the block 704, the connecting rod 702 and the fixed tube 701. This design ensures that the temperature tube 707 can burst smoothly when the preset temperature is reached to activate the spray system. At the same time, this contact design also helps to quickly conduct the temperature and reduce the response time.

[0038] In summary, the portable smoke arrester provided by the utility model achieves efficient and reliable smoke blocking effect at the fire scene through the precise control of the mechanical triggering of its spray assembly, clear temperature indication and reliability of the triggering mechanism. These design features enable the smoke arrester to respond quickly and accurately when a fire occurs, effectively preventing the spread of smoke, protecting the safety of personnel, and reducing the damage of the fire to the surrounding environment.
