The working principle of the invention is explained with reference to fig. 2:
Independent functions:
The fan system has independent and combined functions: the system is composed of one to four groups of fans, each group of fans is independently controlled by the control system, and under the control of the electrical system, the four groups of fans in the system can be independently used in a single group, can be simultaneously used in any combination of two groups or three groups or four groups, and the selected combination functions can also be respectively used independently of other functions.
The fan prevents the function of discharging fume: if the motor in each group of fan systems is provided with the fan in the forward rotation direction for smoke discharge, the motor is controlled in the reverse rotation direction, the fan is used for smoke prevention, and vice versa.
The fan strengthens the state: when the telescopic air pipes are used for connecting all groups of fan systems, for example, the upper air ports are connected, the lower air ports are connected to form an air flow channel, then the rotating directions of the fans are uniformly adjusted under the control of a control system, so that the air pressure which is far greater than that generated by one fan system can be formed, the output capacity of the whole fan system is greatly improved, and the fire extinguishing task with the requirement of longer distance or higher strength can be completed.
The low-power foam extinguishing function is as follows: when the foam tank, the water tank, the pump and the pipeline system directly output foam mixed liquid from the output pipe, the low-power foam fire extinguishing function is achieved.
clear water extinguishment function: when the valves of the foam tank, the water tank, the pump and the foam pipeline in the pipeline system are closed, clean water is output from the pump and the pipeline system, and the clean water fire extinguishing function is realized.
High-power foam extinguishing function: the foam mixed liquid is output under the action of powerful airflow air to generate high-power foam mixed liquid, so that the high-power foam fire extinguishing function is realized.
The combined function is as follows:
The on-off of pipelines among the foam tank, the water tank, the pump, the fan, the smoke prevention and exhaust pipeline and the mobile high-power foam generator can be controlled through a carriage control system, and the forward and reverse rotation directions of all the fans can be controlled; and selecting and connecting each air port of the fan system by using a telescopic air pipe.
The control system realizes any two or multiple function combinations of smoke prevention, smoke discharge, clear water fire extinguishing, low-power foam fire extinguishing and high-power foam fire extinguishing modes by selectively controlling the on-off of a pipeline, or opening and closing of a fan power supply, or opening and closing of a pump and a pipeline system pipeline water tank or a foam tank valve, and selectively using or not using the mobile high-power foam generator, so that a multifunctional fire-fighting fire-extinguishing rescue mode is realized. For example, two groups of fan systems can be controlled to complete smoke discharge, and meanwhile, the air outlets of the other two groups of fan systems are introduced into an input pipeline of the mobile high-power foam generator and mixed with foam solution to generate high-power foam liquid for extinguishing fire. Of course, in the above working condition, if the foam isolation zone is formed near the ground or at the periphery, the pipeline outlet on the pump can be opened simultaneously, and the low-power foam solution is divided into two parts, one part is used for generating high-power foam and the other part is used for generating the foam isolation zone. In addition, various combinations can be performed according to needs, but the core is the organic combination of the fan system and the foam system, and the single fan system or the foam system can be realized.
