Technical Field
[0001] The utility model relates to the technical field of firefighter training equipment, in particular to a real fire simulation combustion pool and a real fire simulation system. Background Art
[0002] In the real fire simulation training of firefighters, in order to simulate the complex combustible composition and combustion forms of different combustibles in real fire scenes, real fire simulation training facilities generally need to be equipped with gas, fuel oil and other combustion media as supporting fuels. In some special real fire simulations, some real combustibles need to be placed. For example, in the simulation facilities that simulate the two extreme combustion phenomena of flashover and backdraft, it is necessary to place real complex combustibles such as firewood, furniture, and bedding to reproduce the real combustion effect, so as to better carry out fire rescue training and practical teaching.
[0003] In order to meet the actual needs of firefighters' real fire training, we have provided a water bath real fire burning pool device on the basis of ensuring the safety and stability of the real fire burning area and ensuring the continuity and repeatability of the real fire burning effect. The device uses the equipped gas and fuel oil to achieve three-level real fire simulation effects of small fire, medium fire and large fire. In addition, real burning objects such as firewood, furniture, and bedding can be placed in this water bath real fire burning pool for burning. The water bath real fire burning pool is equipped with a special real fire simulation facility ignition device to provide the burning pool with a continuous long-burning flame. While achieving the simulated small fire burning effect, it is used to meet the automatic ignition requirements of the burning pool, replacing the traditional manual ignition method, further improving the simplicity of training while improving the controllability of the real fire burning effect.

[0016] In order to meet the actual needs of firefighters' real fire training, it is necessary to be able to burn real combustible objects such as firewood, furniture, and bedding to simulate real fire. The utility model has the following beneficial effects:
[0017] The real fire simulation combustion pool and the real fire simulation system of the utility model can be used for real fire simulation training of firefighters.
[0018] On the one hand, the real fire simulation combustion pool provided by the utility model can provide a platform for supporting real burning objects such as firewood, furniture, and bedding.
[0019] Before the simulation training, the air supply pipe is connected to a fresh air source, the fuel pipe is connected to a fuel supply source, and real combustible materials used for real combustion during simulation are placed on the storage grid of the inner cavity; during the simulation, the fuel supply source is turned on, and the fuel enters the fuel pipe from the feed end and is sprayed out from the nozzle.

[0029] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.
[0030] See also Figure 1-4 The utility model discloses a real fire simulation combustion pool 100 and a real fire simulation system 200, which can be used for real fire simulation training of firefighters. On the one hand, the real fire simulation combustion pool 100 disclosed in the utility model can provide a platform for supporting real burning objects such as firewood, furniture, and bedding. On the other hand, the utility model also provides a real fire simulation system 200, which provides a training platform for real fire combustion simulation and provides a basis for combustion control during the simulation process.
[0031] First, as Figure 1-3 As shown, the real fire simulated combustion pool 100 disclosed in the utility model includes a combustion pool 101, an igniter 110, an air supply pipe 112 and a drainage pipe 116.
[0032] Among them, the combustion pool 101 is provided with an inner cavity 102 with an open top, a fuel pipe 103 and a storage grid 107 are provided in the inner cavity 102, a plurality of nozzles 104 are provided on the fuel pipe 103, a feed end 106 of the fuel pipe 103 extends to the outside of the combustion pool 101, and the storage grid 107 is provided above the fuel pipe 103; an igniter 110 is provided on the combustion pool 101, and an ignition end 111 of the igniter 110 extends into the inner cavity 102; an air supply pipe 112 is provided on the combustion pool 101, and an air outlet 113 of the air supply pipe 112 extends into the inner cavity 102; a drain pipe 116 is provided at the bottom of the inner cavity 102, and a water inlet 117 extends upward, and there is a distance between the water inlet 117 and the bottom of the inner cavity 102, and the water inlet 117 is not higher than the injection port 105 of the nozzle 104.
[0033] Before the simulation training, the air supply pipe 112 is connected to a fresh air source, the fuel pipe 103 is connected to a fuel supply source, and real combustible materials for real combustion during simulation are placed on the storage grid 107 of the inner cavity 102; during simulation, the fuel supply source is turned on, and the fuel enters the fuel pipe 103 from the feed end 106 and is sprayed out from the injection port 105. After the fuel is sprayed out, the fuel and the real combustible materials can be ignited by the ignition end 111 of the igniter 110, and the real combustible materials are quickly ignited by the combustion of the fuel combustible materials for simulation, and then the firefighters can perform extinguishing actions to perform simulation training.
[0034] Among them, in the initial stage, by quickly igniting and supporting the combustion of real combustion materials, the expected fire intensity can be quickly achieved, which saves preparation time and shortens unnecessary time in the simulation process. In the process stage, the fire intensity can be controlled by controlling the fuel injection rate, and various fire states such as small fire, medium fire, and large fire can be simulated, and the deflagration simulation effect can be achieved by suddenly increasing the fuel injection amount.
[0035] In general, if Figure 2 , Figure 3 As shown, the fuel pipe 103 is used to inject oil (diesel) or gas (coal gas) for combustion. However, in order to take into account the different characteristics of oil and gas, two groups of fuel pipes 103 are provided, and each group of fuel pipes 103 is coiled in the inner cavity 102 to ensure sufficient dispersion and sufficient uniform distribution of the supply range. One of the two groups of fuel pipes 103 is dedicated to gas supply, and the other group is dedicated to oil supply.
[0036] In the simulation process, due to the fierce fire and high oxygen consumption, the air supply pipe 112 can continuously provide the oxygen required for combustion. The surrounding side wall of the combustion pool 101 extends upward to a height above the storage grille 107. The igniter 110 and the air supply pipe 112 are both arranged on one side of the combustion pool 101. The ignition end 111 and the air outlet 113 are both above the storage grille. Furthermore, the air outlet 113 is arranged on one side of the inner cavity 102, and the air outlet 113 has a downward tilt angle, such as Figure 3 As shown, the fresh air that supplements the oxygen consumed by combustion is sprayed downwardly and then quickly diffuses and supplements the inner cavity 102. If it is tilted upward, the newly supplemented air will escape from the inner cavity 102 faster, reducing the supplement effect of the oxygen consumed by combustion.
[0037] Among them, water can be added to the inner cavity 102 of the combustion pool 101, and the drainage pipe 116 is set in a way that the fuel pipe 103 and the like can be immersed therein to reduce the impact of the heat radiation of the fire on the fuel pipe 103. At the same time, the water sprayed by the firefighters during the training process can also be discharged in time through the drainage pipe 116, and the water level will not submerge the injection port 105 of the nozzle 104. At the same time, the remaining water level in the combustion pool 101 can also cool down the entire real fire simulation combustion pool 100. Figure 2 As shown, a filter screen 118 is provided at the water inlet 117 to cover the water inlet 117 .
[0038] In order to facilitate cleaning of the interior of the combustion pool 101 after the simulation training is completed, the storage grille 107 is detachable. Specifically, a support platform 108 protruding inward is provided on the side wall of the inner cavity 102, and the storage grille 107 is placed on the upper side of the support platform 108.
[0039] like Figure 1 A support frame 109 is provided under the bottom of the burning pool 101, and a water inlet 117 passes through the bottom of the burning pool 101 and extends upward. Furthermore, a sewage pipe 114 connected to the inner cavity 102 is provided at the bottom of the burning pool 101, and a switch valve 115 is provided on the sewage pipe 114. Firstly, the setting of the frame 109 raises the position of the burning pool 101, which is convenient for the setting of the drainage pipe 116 and the sewage pipe 114. Secondly, it is convenient for the hanging or installation application when the real fire simulation burning pool 100 is used in other scenes.
[0040] Second, as Figure 4As shown, based on the same technical concept of the present invention, the real fire simulation system 200 disclosed in the present invention includes the real fire simulation combustion pool 100 described above; in addition, it also includes a blower 201 connected to the air supply pipe 112, a flame detector 202 that can be arranged around the combustion pool 101, a temperature sensor 203 for detecting the temperature in the inner cavity 102, a control valve 204 for controlling the supply of fuel to the fuel pipe 103, and a controller 205 respectively connected to the control switch of the blower 201, the flame detector 202, the temperature sensor 203, and the control valve 204.
[0041] Among them, the blower 201 is used to provide a fresh air source for the combustion pool 101, the temperature sensor 203 is used to detect the working temperature of the combustion pool 101, and the flame detector 202 is also connected to the controller 205, arranged in the area around the combustion pool 101, to accurately judge the combustion flame in the combustion pool 101, and to control the control valve 204 through the controller 205, so as to automatically cut off the fuel supply of the fuel pipe 103 in time after the fire is extinguished.
[0042] Furthermore, a pressure sensor can be provided for the feed line of the fuel pipe 103 to detect the working pressure, which plays a role in safety protection. The controller 205 can select a PLC control module, and a human-machine interaction device 206 can be provided to improve the convenience of operation, program setting, and program selection, and the human-machine interaction device 206 can record and display the data of each sensor in the simulation process.
[0043] In terms of control, the controller 205 can adjust the fuel supply rate by controlling the control valve 204 .
[0044] During the real fire simulation process, the temperature sensor 203 continuously monitors the working temperature of the combustion pool 101. When the temperature of the combustion area exceeds the designed safety value, it can automatically alarm and automatically cut off the fire and fuel to ensure the safety of the training. After the real fire simulation training is over, the fire and fuel can be cut off with one click.
[0045] Generally, the ignition end 111 of the igniter 110 is provided with an oil spray pipe (jet pipe) and a spark ignition device, and the spark ignition device is used to ignite the oil spray pipe to ignite the ignition. Furthermore, in order to prevent the influence of water spray on the ignition end 111 during fire fighting, a cover for waterproof protection can also be provided on the ignition end 111.
[0046] 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. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
