Technical Field
[0001] The utility model relates to the technical field of filling equipment, in particular to a water-based fire extinguisher filling device. Background Art
[0002] When water-based fire extinguishers are produced, they need to be filled with a surfactant-containing agent and treated pure water. During the canning process, the flow and fall of the fire extinguishing liquid will impact the liquid inside the tank, causing the liquid to be agitated, thereby forming foam and bubbles. As the filling liquid level continues to rise, the foam may overflow from the tank, polluting the surrounding environment and causing waste.
[0003] In order to reduce the occurrence of this phenomenon, in addition to controlling the filling flow rate, the filling pipe is usually extended to the bottom of the tank body, reducing the distance between the filling pipe and the bottom of the tank body, and reducing the drop between the liquids to minimize the generation of filling foam. However, due to the different heights of tanks of different specifications, when filling tanks of different specifications, it is necessary to frequently adjust the depth of the filling pipe into the tank body, which is more troublesome to use. Based on the above situation, it is necessary to design a water-based fire extinguisher filling equipment to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0021] Reference Figure 1-Figure 5 As shown, a water-based fire extinguisher filling device includes a fixing frame 1 and a container 2 for containing water-based fire extinguisher liquid. The container 2 is provided with a filling hose 21 for filling the tank body 11 with liquid. The filling hose 21 is provided with a water pump 22. When in use, the fire extinguisher tank body 11 to be filled can be placed on the fixing frame 1. The fixing frame 1 is provided with a telescopic member 3. The movable end of the telescopic member 3 is connected to a receiving plate 31. The water pump 22 is provided on the receiving plate 31. The bottom end of the receiving plate 31 is connected to an insert 5 with a hollow interior and open ends through a spring 4. The telescopic member 3 can be electric or hydraulic. The mechanism capable of linear reciprocating motion such as a telescopic rod or a linear slide is pressed. When the telescopic member 3 drives the receiving plate 31 to move downward, the insert 5 is driven to be inserted into the interior of the tank body 11 under the connecting action of the spring 4. In order to accurately insert the insert 5 into the tank body 11, a positioning mark for positioning the tank body 11 or a positioning groove for placing the tank body can be provided on the fixing frame 1. The positioning mark coincides with the axis of the insert 5. When the tank body 11 is placed, it is only necessary to place the tank body 11 in the middle of the positioning mark to make the insert 5 enter the interior of the tank body 11. When the receiving plate 31 moves downward, The water pump 22 is driven to move downward synchronously, and the filling hose 21 at the output end of the water pump 22 moves downward synchronously with the water pump 22, and the filling hose 21 at the input end of the water pump 22 is stretched. The filling hose 21 at the input end of the water pump 22 can be designed as a spiral to reduce the risk of winding during resetting. A positioning sleeve 6 is provided on the insert 5. When the positioning sleeve 6 follows the insert 5 to move downward and contacts the tank body 11, the positioning sleeve 6 drives the insert 5 to stop moving downward. At this time, the telescopic member 3 drives the receiving plate 31 to continue moving downward, at which time the spring 4 is compressed, and the filling hose 21 can be moved out of the insert The middle part of the insertion piece 5 passes through and extends to the outside of the insertion piece 5. When the insertion piece 5 stops moving downward, the water pump 22 will continue to move downward following the receiving plate 31, so the output end of the filling hose 21 will also continue to move downward until it contacts the bottom of the tank body 11, until the length of the filling hose 21 entering the tank body 11 is greater than the axial length of the tank body 11, that is, the output end of the filling hose 21 is in a curled state, so that when the water pump 22 fills the liquid through the filling hose 21 again, it can buffer the impact force of the liquid, reduce the turbulence of the liquid, and thus further reduce the generation of bubbles during filling.
[0022] Among them, the insert 5 and the output end of the filling hose 21 enter the tank body 11 synchronously to limit the output end of the filling hose 21, so as to prevent the output end of the filling hose 21 from swinging arbitrarily and failing to accurately enter the interior of the tank body 11. When the filling is completed, the telescopic member 3 drives the receiving plate 31 to reset, and first drives the water pump 22 and the output end of the filling hose 21 to move upward through the receiving plate 31, so that the output end of the filling hose 21 enters the interior or bottom of the insert 5. After that, when the receiving plate 31 moves upward to a state where the spring 4 is not compressed, the insert 5 can be lifted out of the interior of the tank body 11 through the connecting action of the spring 4.
[0023] Further, refer to Figure 5 As shown, the axial center of the positioning sleeve 6 coincides with that of the insert 5, and the inner diameter of the positioning sleeve 6 gradually increases from top to bottom. When the positioning sleeve 6 moves downward synchronously with the insert 5 and is stuck at the upper end of the tank body 11 and cannot continue to move downward, the insert 5 can be stopped from continuing to move downward to avoid the insert 5 continuing to move downward and causing interference with the inner wall of the bottom of the tank body 11. At the same time, it can be stuck at the upper end of the tank body 11 to position the tank body 11 and prevent the tank body 11 from accidentally tipping over.
[0024] Further, refer to Figure 2 As shown, a guide rod 7 is provided on the insert 5, one end of the guide rod 7 passes through the receiving plate 31 and is slidably connected to the receiving plate 31, which can guide the insert 5 so that the insert 5 can move vertically up and down stably, so that the insert 5 can be accurately inserted into the tank body 11, and the guide rod 7 can be located in the middle of the spring 4 to guide the spring 4 to avoid bending when the spring 4 is compressed.
[0025] Further, refer to Figure 4 As shown, in order to prevent the output end of the tank hose 11 from colliding with the inner wall of the tank body 11 when the tank body 11 hose enters the interior of the tank body 11, thereby affecting the liquid discharge effect, the output end of the filling hose 21 is connected to a filling head 23, and a plurality of through holes 24 are opened on the filling head 23. If one of the through holes 24 is blocked by the inner wall of the tank body 11, the liquid can flow out from the remaining through holes 24, and the diameter of the through hole 24 is larger than the diameter of the filling hose 21. When the liquid flows out from the filling hose 21 through the filling head 23, the flow rate changes relatively smoothly, reducing the sharp impact and angle of the liquid, reducing the probability of foam generation, and can more evenly release the pressure of the extrusion force during filling, avoiding excessive pressure in the filling hose 21 causing liquid splashing and foam generation.
[0026] Further, refer to Figure 4As shown, a porous defoaming plate 8 is provided inside the filling head 23, which starts to destroy and suppress the foam that may be formed when the liquid is still in the filling hose 21, preventing a large amount of foam from gushing out from the outlet of the filling head 23, reducing the defoaming pressure in the subsequent tank body 11, and can also play a certain obstruction and buffering role on the flow rate of the liquid, reducing the impact and agitation caused by the high-speed flow of the liquid in the filling hose 21, thereby reducing the possibility of foam formation.
[0027] Further, refer to Figure 5 As shown, the bottom of the insert 5 and the positioning sleeve 6 are both provided with a flexible protective portion 9, which can be made of materials such as rubber or silicone, so as to avoid the wear of the filling hose 21 caused by friction when the output end of the filling hose 21 moves upward and interferes with the bottom end of the insert 5. At the same time, the flexible protective portion 9 can increase the friction with the tank body 11 when the positioning sleeve 6 is stuck on the upper end of the tank body 11, thereby improving the positioning effect of the tank body 11 and avoiding scratches and other damages to the surface of the tank body 11.
