[0040] The controller 5 is electrically connected to the filling pump group 2 , the infusion control valve 3 , the display 6 and the flow meter 4 respectively. The filling pump group 2 is used to connect to a container storing fire extinguishing liquid through the liquid inlet 8 .

[0041] From the above description, it can be seen that the beneficial effects of the utility model are: the filling volume of the filling pump group 2 is monitored in real time by the flow meter 4, and the flow is fed back to the controller 5 for flow control. At the same time, the monitoring results, the operation data of the filling pump group 2 and other information can be displayed on the display screen, and can be moved to the specified position according to the filling needs. While controlling and intuitively reflecting the filling volume, there is no need to carry out the filling bottle handling operation, which reduces the duration of the filling operation and reduces the labor cost.

[0042] Furthermore, the filling assembly further comprises a frequency converter 9;

[0043] The controller 5 is electrically connected to the filling pump group 2 via the frequency converter 9 .

[0044] From the above description, it can be seen that the frequency converter 9 is provided to flexibly control the motor speed of the filling pump group 2, thereby adjusting the impact force of the fire extinguishing liquid during filling according to the actual filling progress during the filling process. For example, when a bottle is almost full, the motor speed is reduced to slow down the filling fluid speed.

[0045] Furthermore, the filling assembly also includes an alarm 10;

[0046] The alarm device 10 is disposed on the mobile vehicle 1 , and the controller 5 is electrically connected to the alarm device 10 .

[0047] As can be seen from the above description, by providing the alarm 10, some filling process events such as the filling pump group 2 stopping unexpectedly, the bottle being filled, etc. can be prompted, so that the operator can handle them in time.

[0048] Furthermore, the mobile vehicle 1 includes a mobile base plate 11 and a protective shell 12;

[0049] The protective shell 12 is disposed on the movable bottom plate 11, and the filling pump group 2, the infusion control valve 3, the flow meter 4 and the controller 5 are all located in the protective shell 12;

[0050] The liquid outlet 7 and the liquid inlet 8 are both located on the surface of the protective shell 12 .

[0051] From the above description, it can be seen that by providing the protective shell 12, protection is provided for the filling pump group 2 and other components to avoid some external interference during the operation process, reduce the difficulty of maintenance, and improve the aesthetics of the equipment.

[0052] Furthermore, the protective housing 12 is provided with a first installation chamber 13 and a second installation chamber 14 in sequence from top to bottom;

[0053] The controller 5 is located in the first installation room 13, and the filling pump group 2, the infusion control valve 3 and the flow meter 4 are all located in the second installation room 14;

[0054] The display 6 is located on the top of the protective housing 12 .

[0055] From the above description, it can be seen that the display 6 is arranged on the top of the protective shell 12, and the first installation room 13 and the second installation room 14 are arranged in layers, so that the controller 5 and the filling pump group 2 are placed separately, and the role and weight of the components are fully considered to optimize the layout of the equipment components for easy maintenance.

[0056] Furthermore, the movable bottom plate 11 is provided with a ventilating opening;

[0057] A support rod 15 is arranged at the vent, and the filling pump group 2 is located on the support rod 15 .

[0058] From the above description, it can be seen that by providing the vents, the air flow inside and outside the protective shell 12 can be increased, the motor of the filling pump group 2 can be helped to dissipate heat, etc., the internal temperature can be reduced, and the operation stability of the equipment can be improved.

[0059] Further, a reflux device 16 is included;

[0060] The reflux device 16 is located on the moving vehicle 1 , and the reflux device 16 is connected to the transmission pipe.

[0061] From the above description, it can be seen that the reflux device 16 is provided to recover the fire extinguishing liquid remaining in the transmission pipe after the filling is completed, so as to avoid unnecessary waste.

[0062] Furthermore, the filling assembly also includes a filling tube;

[0063] One end of the filling tube is connected to the liquid outlet 7, and the length of the filling tube is adjustable.

[0064] As can be seen from the above description, a filling tube with adjustable length is assembled to facilitate flexible connection of the filled bottles and reduce the need to move the equipment.

[0065] Furthermore, the filling tube is formed by splicing at least two extension tubes;

[0066] The adjacent extension tubes are detachably connected.

[0067] From the above description, it can be seen that the filling tube is made of at least two extension tubes. During the filling operation, the filling distance and angle can be changed according to the way of adding the extension tube, especially when filling batches of bottles, which can effectively improve the operation efficiency.

[0068] Furthermore, the display 6 is provided with a touch button, and the touch button is electrically connected to the controller 5 .

[0069] It can be seen from the above description that touch buttons are provided on the display 6 to achieve centralized control and reduce the difficulty of operation.
