referring to fig. 5, the difference between the second embodiment and the first embodiment is that the control device 11 includes two pressing rods 113 and two linear driving assemblies 114, the two pressing rods 113 respectively correspond to the two flexible tubes 81 one by one, the two pressing rods 113 also respectively correspond to the two linear driving assemblies 114 one by one, the pressing rods 113 are located on one side of the flexible tubes 81 far away from the bottom wall of the mounting cylinder 5, and the pressing rods 113 are pressed against the flexible tubes 81. The linear driving assembly 114 can be a linear motor and can also be a screw thread pair, in this embodiment, the linear driving assembly 114 is configured as a screw thread pair, one end of the pressing rod 113 is connected with an output end of the screw thread pair, and the screw thread pair can drive the pressing rod 113 to slide in the installation cylinder 5 in a reciprocating manner along the length direction of the installation cylinder 5.
In the second embodiment of the present application, an implementation principle of a fire control system is as follows: when the fire of ignition is high, can start sharp drive assembly 114, sharp drive assembly 114 orders depression bar 113 to slide towards the direction that is close to the installation section of thick bamboo 5 diapire, and depression bar 113 pushes down flexible tube 81 to reach the purpose of adjusting the length that flexible tube 81 stretches out installation section of thick bamboo 5, adjusted lateral shower nozzle 7 to the distance between the ignition, avoid flexible tube 81 and lateral shower nozzle 7 to be damaged by high temperature as far as possible, ensured lateral shower nozzle 7 to the stable injection of ignition.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
