[0030] The control mechanism includes a support plate 25 connected to the docking reinforcement cylinder 31, and a motor 26 and a screw 27 are arranged on the support plate 25.

A rack 230 is arranged on the telescopic rod of the rack electric cylinder 29. The rack 230 is meshed with a control gear ring 35 to drive the control gear ring 35 to rotate.

[0031] The operation principle is as follows: by connecting the filling connecting pipe 4 to the external fire-fighting pipeline, water source filling is carried out. In a low temperature environment, antifreeze can be added through the antifreeze filler 3 to prevent the pipe from freezing; specifically, the water source is transmitted to the docking transmission pipe 12 through the filling pump 8, and then filled into the tank body 2 through the nozzle 37 on the docking transmission pipe 12. The nozzle 37 is in a matching relationship with the filling valve 24 at the bottom of the tank body 2. During the docking, the nozzle 37 is docked with the docking reinforcement cylinder 31, and the rack electric cylinder 29 controls the rack 2 30 to engage with the control gear ring 35, and then the motor 1 26 works, the turntable 17 rotates, the screw slide 28 slides, and then the rack 2 30 moves to drive the control gear ring 35 to rotate, so that the gear 36 and the reinforcement pressing seat 38 rotate, and the contact part 39 rotates to the bottom of the clamping telescopic shaft 32, and the spherical end of the clamping telescopic shaft 32 is squeezed and contacted with the contact part 39 to play a reinforcement role.

When the water hits the impact plate 16, the pressure sensitive element 1601 can output a feedback pressure change signal.
