[0009] 1. For the discharging device for producing the water-based fire extinguishing agent, the driving of the electric telescopic rod can drive the adapter to move up and down while adjusting the height of the liquid outlet pipe. Thus, the discharging device can be used for filling tanks with different heights. Meanwhile, the pressure sensor can detect the pressure acting on the limit disc and the controller can control the driving of the electric telescopic rod. Therefore, the length of the liquid outlet pipe inserted into the tank can be limited by the limit disc, ensuring that when the device is used for filling tanks with different heights, the water-based fire extinguishing agent is not easily splashed outside the tank, and its applicability range is relatively large.

[0010] 2. For the discharging device for producing the water-based fire extinguishing agent, the filter screen can filter and remove impurities from the gas entering the second intake pipe, and the activated carbon can dehumidify the filtered air, ensuring that the air entering the liquid storage tank driven by the air pump is relatively dry, reducing the influence of air on the concentration of the water-based fire extinguishing agent. At the same time, the humidity sensor can detect the air humidity inside the second intake pipe, facilitating the regular replacement of the activated carbon by removing the sealing cover.

[0017] The following further elaborates on the present application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for ease of description, only the parts related to the utility model are shown in the drawings.

[0018] The accompanying drawings in the embodiments of the present utility model: The different types of hatching lines in the figure are not marked according to the national standard, nor are the materials of the components required. They are used to distinguish the cross-sectional views of the components in the figure.

[0019] Please refer to Figures 1-4, A discharging device for the production of water-based fire extinguishing agent, comprising a liquid storage tank 1, a liquid discharge pipe 2 connected to the bottom of the liquid storage tank 1, a liquid inlet pipe 3 and a first air inlet pipe 4 connected to the top of the liquid storage tank 1, an air pump 5 fixedly installed on the top of the liquid storage tank 1, and a valve 6 installed on the liquid inlet pipe 3. By driving the air pump 5, air can be filled into the interior of the liquid storage tank 1 while increasing the pressure inside the liquid storage tank 1. Then, under the action of air pressure, it is convenient to discharge the water-based fire extinguishing agent inside the liquid storage tank 1 through the outside of the liquid discharge pipe 2. A controller 7 electrically connected to the air pump 5 and a fixing plate 8 arranged on the outside of the liquid storage tank 1 are fixedly installed on the outside of the liquid storage tank 1. A barometer 9 electrically connected to the controller 7 is fixedly sleeved on the top of the liquid storage tank 1. The barometer 9 can detect the air pressure inside the liquid storage tank 1 and can control the driving of the air pump 5 through the controller 7 at the same time. A rotary joint 11 is connected inside the liquid discharge pipe 2 through a hose 10. During the up and down movement of the rotary joint 11 through the hose 10, the liquid discharge pipe 2 and the rotary joint 11 can always be connected through the hose 10. The rotary joint 11 is connected to a solenoid valve 13 through a flow meter 12, and the flow meter 12 and the solenoid valve 13 are electrically connected to the controller 7. One side of the solenoid valve 13 is connected to a rotary joint 14, and the inside of the bottom of the rotary joint 14 is connected to a liquid outlet pipe 15. A limiting mechanism 16 is arranged on the outside of the rotary joint 14 and outside the liquid outlet pipe 15. A lifting mechanism 17 is fixedly sleeved inside the fixing plate 8. One side of the air pump 5 is connected to a filtering mechanism 18.

[0020] Among them, the lifting mechanism 17 includes an electric telescopic rod 171 fixedly sleeved inside the fixing plate 8 and electrically connected to the controller 7, a distance sensor 172, and a third fixing block 173 arranged on the outside of the rotary joint 14. A fixing rod 174 movably sleeved inside the fixing plate 8 is fixedly sleeved inside the third fixing block 173. The distance between the third fixing block 173 and the fixing plate 8 can be detected through the distance sensor 172. Then, the driving of the electric telescopic rod 171 can be controlled through the controller 7, and at the same time, the distance of the liquid outlet pipe 15 retracting from the inside of the tank can be controlled, so that when the high discharging device performs filling operations on tanks of different heights, the distance of the liquid outlet pipe 15 inserted into and removed from the inside of the tank each time is the same, thereby improving the filling efficiency of the discharging device.

[0021] Among them, the limiting mechanism 16 includes a first fixing block 161 and a second fixing block 162 arranged outside the adapter 14. A first guide rod 163 is movably sleeved inside the first fixing block 161. A second guide rod 164 and a pressure sensor 165 fixedly sleeved and electrically connected to the controller 7 are movably sleeved inside the second fixing block 162. A limiting disc 166 located outside the liquid outlet pipe 15 is jointly arranged at the bottoms of the first fixing block 161 and the second fixing block 162. Clamping rings 167 are clamped on the outer sides of the tops of the first fixing block 161 and the second fixing block 162. The clamping rings 167 can limit the first guide rod 163 and the second guide rod 164 and prevent the limiting disc 166 from falling off the outside of the liquid outlet pipe 15. When the tank body contacts the limiting disc 166, the pressure generated is detected by the pressure sensor 165 and the driving of the electric telescopic rod 171 is controlled, so as to ensure that the length of the liquid outlet pipe 15 inserted into the tank body each time is the same.

[0022] Among them, the filtering mechanism 18 includes a second air inlet pipe 181 communicated with one side of the air pump 5. A humidity sensor 182 fixedly sleeved and electrically connected to the controller 7 is fixedly sleeved inside the second air inlet pipe 181. A sealing cover 183 is threadedly sleeved on the outer side of one end of the second air inlet pipe 181. Activated carbon 184 is sleeved inside the sealing cover 183. A filter screen 185 is arranged inside the outer side of the sealing cover 183. The humidity sensor 182 can detect the air humidity inside the second air inlet pipe 181. When the detected humidity value exceeds the set value, information can be transmitted to the controller 7, and then an alarm is given through the buzzer inside the controller 7, so that the operator can replace the activated carbon 184 by disassembling the sealing cover 183.

[0023] Among them, a buzzer is arranged inside the controller 7, and an alarm can be given through the buzzer to facilitate the operator to perform maintenance operations on the unloading device.

[0024] When the unloading device is working, place the tank body directly below the liquid outlet pipe 15. Start the electric telescopic rod 171 through the controller 7. While driving the adapter 14 to move downward by the drive of the electric telescopic rod 171, gradually insert the liquid outlet pipe 15 into the interior of the tank body. When the pressure sensor 165 detects pressure on the limit disc 166, control the electric telescopic rod 171 to close and start the air pump 5 through the controller 7. Drive the outside air into the interior of the liquid storage tank 1 through the second air inlet pipe 181 and the adapter 14 by the drive of the air pump 5. During this process, filter and dehumidify the air through the filter net 185 and the activated carbon 184, and be able to detect the humidity inside the second air inlet pipe 181 through the humidity sensor 182. When the humidity sensor 182 detects that the humidity value is greater than the set value, it can transmit the information to the controller 7 and give an alarm reminder through the buzzer inside the controller 7. Start the solenoid valve 13 through the controller 7. At this time, the aqueous fire extinguishing agent inside the liquid storage tank 1 is conveyed to the interior of the liquid outlet pipe 15 under the action of air pressure through the drain pipe 2, the hose 10, the adapter 11, the flow meter 12, the solenoid valve 13 and the adapter 14. At this time, fill the aqueous fire extinguishing agent into the interior of the tank body through the liquid outlet pipe 15. Detect the flow rate of the aqueous fire extinguishing agent conveyed into the hose 10 through the flow meter 12. When the flow meter 12 detects that the conveyed flow rate reaches the set value, close the air pump 5 and the solenoid valve 13 and start the electric telescopic rod 171 through the controller 7. Drive the liquid outlet pipe 15 out of the interior of the tank body by the drive of the electric telescopic rod 171. Detect the moving distance of the third fixing block 173 through the distance sensor 172. When the third fixing block 173 moves to the set value, close the electric telescopic rod 171 through the controller 7 to complete the filling operation of a single tank body.
