[0003] As an advanced training facility, indoor pyrotechnic characteristic fire fighting training container can provide firefighters with a more realistic and practical training environment, which has important practical significance;But in the existing indoor pyrotechnic characteristic fire fighting training container, the problem of low smoke concentration and the problem of flame spouting effect when the combustion chamber is opened cannot be realized, so that the smoke scene in real fire cannot be simulated, thereby seriously affecting the training effect of the training personnel.Due to the insufficient smoke generation of the smoke generation system, the smoke concentration in the training environment is difficult to reach the low visibility condition of real fire, so that the training personnel cannot fully adapt to the operation difficulty in complex environment, and the continuity and uniformity of the smoke are not good, which further reduces the realism and continuity of the training;At the same time, the flame spouting effect is not obvious when it is opened, the dynamic change of flame in real fire, high temperature radiation and the influence on the surrounding environment cannot be simulated, and the controllability of flame is insufficient, which limits the diversity and complexity of training, so that the skill training and tactical training such as fire extinguishing, search and rescue and breaking are difficult to achieve the expected effect, the training personnel are difficult to overcome the fear of fire, and it is difficult to keep calm and decisive in real fire. CONTENT OF THE UTILITY MODEL

CONCRETE IMPLEMENTING METHOD

[0022] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model will be described below through the specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary and not to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] A kind of container type combustion chamber for indoor pyrotechnic characteristic fire fighting training, as shown in Figures 1 to 4 , including container body 1, there is a closed combustion area 2 in container body 1;Cross in the middle of container body 1 is provided with the partition wall 3 for isolating combustion area 2 and other areas in container body 1, the partition wall 3 is installed with the observation door 4 for observing the internal combustion condition in training box during the process of attack drill, and smoke is scattered through the door hole and realizes the flame eruption effect when opening;The lower side of the side wall of the both sides of container body 1 corresponding to combustion area 2 is respectively provided with a box side air inlet 5 for closing area air inlet, facilitating the ignition of combustion material in combustion area 2, and facilitating the combustion of a proper amount of air into the closed area after closing observation door 4.

[0024] In the drill stage, when opening observation door 4, external air inflow, at the same time, smoke will not flow out too fast in container body 1, smoke layer will continue to accumulate at the top of container body 1, sufficient air will accelerate the chemical reaction of combustible material, at the same time, combustion speed is accelerated, temperature is rapidly increased, flame becomes bright and strong, heat generated by combustion is rapidly released, so that the temperature in the originally closed space of container body 1 sharply rises, and the phenomenon of flame eruption is caused.

[0025] As Figure 1 , Figure 2 and Figure 4As shown in the drawings, a box side combustion observation window 6 for observing the internal combustion during the combustion process is further arranged on the upper left side of the side wall of the container body 1 corresponding to each box side air inlet 5, which is a square window with a size of 40cm*40cm, and is located in the middle and lower part of the container body. In the initial stage of combustion, because the smoke will rise due to thermal convection and chimney effect, this installation position can more clearly and timely observe the state of the combustion material, and the window size is sufficient for the worker to intervene, such as adding combustion material, using tools to stir, etc.

[0026] As shown in the drawings, Figure 1 , Figure 3 and Figure 4 , the partition wall 3 is a wall body for partitioning the combustion space, which is cut from structural steel groove red bricks, yellow mud and fire-retardant adhesive. An observation small window 7 for observing the internal combustion is further arranged on the observation door 4 of the partition wall 3. Among them, the box side air inlet 5 is a square window with a size of 30cm*30cm, and is installed at the lower corner of the container body, 20cm or lower from the bottom and 30cm from the box edge. The design size of the window can make the entering air not excessive or insufficient. Excessive air will make the combustion very intense, and sufficient oxygen will accelerate the chemical reaction of the combustion material, resulting in faster combustion speed and rapid temperature rise. In this case, the flame will become bright and strong, and the heat generated by combustion will be released quickly, which may cause the temperature in the enclosed space to rise sharply, and even cause the phenomenon of flashover. Excessive oxygen in the air will also cause more carbon dioxide and water vapor to be generated, accelerating the consumption of the training container body 1, while the amount of smoke generated is reduced. Insufficient air will make the combustion material not fully burned, and the combustion speed will be significantly slowed down, and even possibly extinguished. At the same time, the design position of the structure can make the air enter from the bottom, and the smoke will rise due to thermal convection and chimney effect, and will not be completely lost through the air inlet, thereby achieving the purpose of increasing the smoke concentration generated by the combustion chamber.

[0027] Secondly, the outer protective layer of the container type combustion chamber door 8 uses heavy steel plate as the outer protective layer, the middle layer uses double-sided color steel + 50mm, density 80KG rock wool fireproof cotton color steel sandwich board, and the inner layer (fire layer) uses high-density fire-resistant high-temperature-resistant fireproof cotton for fire protection.

[0028] The above-described embodiments are only preferred embodiments of the present application, and do not limit the scope of the present application. Any equivalent changes made in shape, structure and principle according to the present application should be covered within the protection scope of the present application.
