[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A device for detecting the fireproof performance of nano thermal insulation cotton comprises a shell 1, the inner wall of the shell 1 is fixedly connected with a bearing plate 2, the bearing plate 2 is used to bear the nano thermal insulation cotton, the inner wall of the shell 1 is fixedly connected with a partition plate 3, a gas nozzle 4 and an igniter 5 are fixedly installed at the bottom of the partition plate 3 and above the bearing plate 2, and the igniter 5 is arranged on one side of the gas nozzle 4.

[0026] The top of the shell 1 is fixedly connected to a water tank 6, and the bottom of one side of the water tank 6 is fixedly connected to a water inlet pipe 7. One end of the water inlet pipe 7 passes through the shell 1 and extends to the interior of the shell 1. A solenoid valve 8 is arranged on the water inlet pipe 7. One end of the water inlet pipe 7 located inside the shell 1 is inclined. The inner wall of the shell 1 is fixedly connected to a clamping mechanism, which is used to press the nano thermal insulation cotton onto the supporting plate 2.

[0027] like Figure 1 and Figure 5 The shell 1 and the carrier plate 2 are both made of fireproof and heat-insulating materials. There is an opening on the outside of the shell 1, which is convenient for putting the nano-insulating cotton into the shell 1 or taking it out of the shell 1. There is a box door on the outside of the shell 1 that can close the opening. The lowest point of the opening on the shell 1 is higher than the height above the carrier plate 2, so that a cavity is formed in the shell 1 below the carrier plate 2. There is an opening on the carrier plate 2, so that water above can fall into the cavity below the carrier plate 2. Each time the solenoid valve 8 is opened, it will start for a fixed time, so that the water entering the cavity below the carrier plate 2 exceeds the carrier plate 2 and the nano-insulating cotton above, but will not leak out from the opening on the shell 1.

[0028] A controller 10 is fixedly mounted on one side of the housing 1 , and the controller 10 and the igniter 5 are connected via a wire.

[0029] like Figure 1 and Figure 2 The controller 10 can control the ignition of the igniter 5, and the connection line between the controller 10 and the igniter 5 is located above the partition plate 3, so that the partition plate 3 can provide protection for the line.

[0030] A gas inlet pipe 11 is fixedly connected to the top of the gas nozzle 4 and located above the partition plate 3 , and one end of the gas inlet pipe 11 extends to the outside of the shell 1 .

[0031] As shown in 1 , the gas inlet pipe 11 is located above the partition plate 3 , and the valves for controlling the gas inlet and preventing backfire are located on the external pipeline or equipment connected to the gas inlet pipe 11 .

[0032] An air inlet pipe 12 and a water outlet pipe 13 are fixedly connected to one side of the housing 1 . A one-way valve 14 is installed on the air inlet pipe 12 , and a control valve 15 is installed on the water outlet pipe 13 .

[0033] like Figure 1 The one-way valve 14 on the air inlet pipe 12 ensures that external air can only enter the shell 1, and the gas inside the shell 1 cannot pass through the air inlet pipe 12. One end of the water outlet pipe 13 is connected to the cavity inside the shell 1 located below the bearing plate 2.

[0034] An exhaust pipe 16 is provided on one side of the shell 1, one end of the exhaust pipe 16 extends to the inside of the shell 1, and the other end of the exhaust pipe 16 is bent downward and extends to the inner bottom of the water tank 6. An exhaust fan 161 is provided on the exhaust pipe 16, and a connecting air port 601 is fixedly connected to the top of the water tank 6.

[0035] like Figure 1 The exhaust pipe 16 is located at one end inside the water tank 6, inside the water body inside the water tank 6, and can be used to replenish water in the water tank 6 through the connecting air port 601.

[0036] The clamping mechanism includes a fixed block 17, which is fixed to the inner wall of the shell 1. A threaded rod 18 is threadedly connected to the fixed block 17, and a clamping plate 19 is rotatably connected to the bottom of the threaded rod 18. A limiting convex plate 20 is fixedly connected to the inner wall of the shell 1, and the limiting convex plate 20 and the clamping plate 19 are slidably connected.

[0037] like Figure 1 and Figure 4 , the limiting convex plate 20 and the clamping plate 19 are slidingly connected, so that the clamping plate 19 can only move up and down. Manually rotating the threaded rod 18 in different directions can drive the clamping plate 19 to move up and down. When the nano thermal insulation cotton to be tested is placed on the top of the supporting plate 2, the clamping plate 19 is moved down to compress and fix the nano thermal insulation cotton.

[0038] The working principle of the nano thermal insulation cotton fireproof performance detection device provided by the utility model is as follows:

[0039] When the nano thermal insulation cotton is fixed on the bearing plate 2, the gas enters the gas nozzle 4 through the gas inlet pipe 11 and is sprayed out, and the igniter 5 ignites to test the fireproof performance of the nano thermal insulation cotton;

[0040] When the nano thermal insulation cotton produces smoke, the exhaust fan 161 can be started, and the exhaust pipe 16 draws out the smoke inside the shell 1 and inputs it into the water body in the water storage tank 6. The water body is used to absorb particulate impurities in the smoke to purify the air. Finally, the gas is discharged to the outside from the connecting air port 601.

[0041] When the nano thermal insulation cotton is ignited due to its insufficient fireproof performance, the solenoid valve 8 can be opened, and the water inside the water tank 6 can be sprayed onto the nano thermal insulation cotton through the water inlet pipe 7 and accumulated in the shell 1 until the water level exceeds the nano thermal insulation cotton, so as to quickly extinguish the fire of the nano thermal insulation cotton, and finally open the control valve 15 to drain the water.

[0042] Compared with the related art, the nano thermal insulation cotton fireproof performance detection device provided by the utility model has the following beneficial effects:

[0043] The utility model can detect the fireproof performance of the nano thermal insulation cotton by arranging a water tank 6 and an exhaust pipe 16, and the generated smoke is discharged after being adsorbed by particulate impurities in the water tank 6, thereby purifying the air. At the same time, when the nano thermal insulation cotton is ignited due to insufficient fireproof performance, the water in the water tank 6 can be input into the shell 1 for fire extinguishing, thereby avoiding safety hazards caused by untimely fire extinguishing.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
