An existing liquid level sensor can be set at the bottom of the liquid storage barrel 20 to detect the usage of the liquid medicine inside the liquid storage barrel 20.

Three docking holes 34 are arranged around and through the gear plate 32, the three docking holes 34 are coaxially aligned and matched with a plurality of circular holes 7 respectively, the docking holes 34 can be coaxially aligned and matched with the slotted holes 8, that is, the docking holes 34 can also be coaxially aligned with the drug storage cartridge 10 or the support cylinder 19. The docking hole 34 can pass under the drug storage cartridge 10 or the support cylinder 19. Three arc-shaped rods 36 are slidably provided on the gear plate 32, and the three arc-shaped rods 36 can be slidably set into the three docking holes 34 respectively. Three motors 37 are fixed on the gear plate 32, and the three motors 37 are respectively used to drive the three arc-shaped rods 36 to slide and move.

When the gear disc 32 rotates, it can slide through the bottom notches of the drug storage barrels 10 and the support barrel 19. When the gear disc 32 is at the bottom of the drug storage barrel 10 or the support barrel 19, it has a blocking effect, which can ensure that the tablets inside the drug storage barrel 10 will not fall, and the telescopic end 21 of the liquid storage barrel 20 inside the support barrel 19 will not telescope downward. The arc rod 36 can also play the same blocking effect as the gear disc 32. Two platform plates 35 are also fixed on the top box body 4.

[0035] The above electrical devices can all be controlled by the PLC system.

[0036] When the present invention is used, the medicine can be pre-added in the liquid storage barrel 20 of the drug storage barrel 10 and the support barrel 19 and sealed. After that, when the main pipeline 1 is circulating water normally, part of the water will flow through the connecting pipeline 2, and as the water flow speed inside the main pipeline 1 increases, the water flow inside the connecting pipeline 2 will also increase. At the same time, the ball valves at both ends of the connecting pipeline 2 can also control the water speed inside the connecting pipeline 2. The water flow passes through the connecting pipeline 2 and can impact the blades on the two rotors 15, thereby driving the two rotors 15 to rotate. The two rotors 15 respectively drive the corresponding driving pulleys 16 and the two driving pulleys 17 to rotate. At the same time, the faster the water flow speed, the faster the rotation speed. The driving pulley 16 can drive the driven gear 33 to rotate, and the driven gear 33 can drive the gear plate 32 to rotate, and drive the disc 5 to rotate. At this time, an arc rod 36 with three docking holes 34 can be set, that is, the motor 37 can control the arc rod 36, so that the arc rod 36 can be set in the corresponding docking hole 34.

[0037] If it is necessary to add a fixed agent, that is, to add solid tablets, the arc rod 36 can be rotated to the side in advance when the docking hole 34 passes under the drug storage barrel 10, so that the docking hole 34 is exposed. At this time, the medicine can fall from the inside of the drug storage barrel 10 and fall into a circular hole 7 of the disc 5 through the slot 8. Thereafter, the disc 5 rotates so that the circular hole 7 first passes through and aligns with the feed hole 6. At this time, the medicine is drawn into the inside of the columnar box body 3 along with the water flow flowing inside the columnar box body 3. The filter screen of the columnar box body 3 prevents the tablets from rushing out of it. The tablets in the columnar box body 3 can be flushed with the water flow to achieve a slow-release flushing effect, thereby achieving a continuous disinfection operation effect. At the same time, flexible settings for adding medicines can be made according to the water quality. That is, by adjusting the water flow rate inside the connecting pipe 2, the rotation speed of the gear plate 32 can be adjusted, thereby adjusting the frequency of adding medicines, or the arc rod 36 in the three docking holes 34 can be flexibly controlled. For example, only one docking hole 34 is set to move the arc rod 36 when passing through the medicine storage cartridge 10, that is, only one docking hole 34 is set for the medicine feeding operation, thereby reducing the frequency of medicine feeding, and can cooperate with the adjustment of the water flow rate to realize the flexible setting of the frequency of adding medicines, effectively improve the utilization rate of the medicines, and reduce the waste of medicines.

[0038] If it is necessary to add liquid medicine, that is, when adding liquid medicine, it can be set that the arc rod 36 is rotated to the side in advance when the docking hole 34 passes under the support tube 19, so that the corresponding docking hole 34 is exposed. At this time, the docking holes 34 are aligned, and the liquid storage barrel 20 at the bottom of the liquid storage barrel 20 corresponds to the slot 8. There is no obstruction at the lower end of the telescopic end 21. The telescopic end 21 can move downward under the action of the spring. At this time, the vertical tube 22 can move along the sleeve 23, so that the strip hole 25 connects the liquid storage barrel 20 and the inside of the telescopic end 21, so that the liquid inside the liquid storage barrel 20 flows into the inside of the telescopic end 21, and the liquid flows out from the opening of the telescopic end 21, and the medicine can fall from the inside of the liquid storage barrel 20 to a corresponding circular hole 7, and then the disc 5 rotates until the circular hole 7 passes through and aligns with the feed hole 6 first. At this time, the medicine liquid is drawn into the inside of the columnar box body 3 along with the water flow flowing inside the columnar box body 3. The medicine liquid in the columnar box body 3 can be mixed with the flushing of the water flow to achieve the effect of the disinfection operation. The same as the operation of solid tablets, the frequency of adding liquid medicine can also be adjusted. At the same time, solid tablets and liquid medicine can be selectively controlled according to the addition requirements, and the two will not mix.

[0039] In the above operation, the circular hole 7 to be loaded first passes through the drainage hole 9. Water will accumulate in the circular hole 7 when it passes through the feed hole 6. As the disc 5 rotates inside the top box body 4, the water inside the circular hole 7 will not flow out, and the circular hole 7 first moves to the position corresponding to the drainage hole 9. At this time, the water inside the circular hole 7 can be discharged from the drainage hole 9. The drainage hole 9 can be connected to a drainage pipe to perform water discharge operation, and it is also convenient to perform sampling operation on the discharged water.

[0040] In the above operation, if the tablets in the corresponding medicine storage cartridge 10 are used up or the medicine in the corresponding liquid storage barrel 20 is used up, the electric telescopic rod 30 is controlled to drive the two rubber rods 31 to move upward and squeeze and insert into the through holes of the first driven pulley 14 and the first linkage pulley 18, as well as the through holes of the second driven pulley 26 and the second linkage pulley 27, respectively. At this time, the first driven pulley 14 and the first linkage pulley 18 can achieve the effect of synchronous rotation through the inserted rubber rod 31, and the second driven pulley 26 and the second linkage pulley 27 can also achieve the effect of synchronous rotation through the inserted rubber rod 31, that is, the rotation of the first linkage pulley 18 can drive the corresponding first driven pulley 14 to rotate, and the rotation of the second linkage pulley 27 can drive the corresponding second driven pulley 26 to rotate. Finally, the first pulley 13 is driven to rotate and the second pulley 24 is driven to rotate, so as to realize the rotation adjustment of the positions of several medicine storage cartridges 10 or several support cylinders 19. At the same time, several drug storage cartridges 10 can also be used to add tablets of different sizes, that is, by adjusting the gap between the two arc-shaped shells 11, several solid tablets can be stacked and placed in a matching manner, or different components of medicines can be set accordingly. Finally, the positions of several drug storage cartridges 10 can be adjusted to achieve the flexible addition of required tablets. Similarly, several liquid storage barrels 20 can be used to set medicines of different components, and the positions can be adjusted to achieve the flexible addition of required liquid medicines.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
