Specific implementation manners

[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] See Figure 1 , Figure 2 , Figure 3 , Figure 4, the present utility model provides an intelligent fully automatic downhole chemical dosing device. The intelligent fully automatic downhole chemical dosing device includes an industrial robot 2, a bagged powder stack 1, a chemical dissolution tank 12, and a reserve bin 7 arranged in sequence. The bagged powder stack 1 is located between the industrial robot 2 and the chemical dissolution tank 12. The arm of the industrial robot 2 is provided with a bag gripper 4, and the bag gripper 4 can grab the bagged powder 16 on the bagged powder stack 1 and transport the bagged powder 16 to the position of the chemical dosing port 13 at the top of the chemical dissolution tank 12 along with the movement of the arm of the industrial robot 2. The movable distance of the bag gripper 4 is greater than the distance from the bagged powder 16 on the bagged powder stack 1 to the bag opening knife 15, which can ensure that the bag opening knife 15 can cut open the bagged powder 16. Both the chemical dissolution tank 12 and the reserve bin 7 are provided with a high liquid level gauge 5 and a low liquid level gauge 10. The high liquid level gauge 5 has a certain distance from the top of the box body where it is located, and the low liquid level gauge 10 has a certain distance from the bottom of the box body where it is located. The high liquid level gauge 5 and the low liquid level gauge 10 can respectively monitor two water level heights. When the water level in the chemical dissolution tank 12 reaches the position of the high liquid level gauge 5, the first electromagnetic water valve 19 of the water supply pipe 18 at the top of the chemical dissolution tank 12 closes and stops chemical dosing; when the water level in the chemical dissolution tank 12 reaches the position of the low liquid level gauge 10, the first electromagnetic water valve 19 of the water supply pipe 18 at the top of the chemical dissolution tank 12 opens for water addition and starts chemical dosing; when the water level in the reserve bin 7 reaches the position of the high liquid level gauge 5, the first water pump 29 in the chemical dissolution tank 12 stops working and no longer transports the uniformly concentrated chemical agent in the chemical dissolution tank 12 into the reserve bin 7; when the water level in the reserve bin 7 reaches the position of the low liquid level gauge 10, the first water pump 29 in the chemical dissolution tank 12 starts working to transport the uniformly concentrated chemical agent in the chemical dissolution tank 12 into the reserve bin 7.

[0025] See Figure 1 , Figure 2 , Figure 3 , Figure 4, preferably, when the bag gripper 4 grabs the bagged powder 16 and transports it to the central position of the medicine adding port 13, the moving direction is along the blade direction of the bag opening knife 15 and the bottom of the bagged powder 16 is slightly lower than the blade. The bag opening knife 15 is located above the medicine adding port 13 and is fixed to the medicine dissolving tank 12 through the second fixing frame 14, which can ensure that the powder falls into the interior of the medicine adding port 13 after the packaging bag of the bagged powder 16 is cut. The driving component of the first stirrer 11 is fixed to the top of the box body of the medicine dissolving tank 12, while the stirring component of the first driver 28 is located at the bottom inside the medicine dissolving tank 12; the driving component of the second stirrer 6 is fixed to the top of the box body of the storage bin 7, and the stirring component of the second stirrer 6 is located at the bottom inside the storage bin 7. The first water pump 29 connecting the storage bin 7 is fixed inside the medicine dissolving tank 12, and the second water pump 9 communicating with the outside is fixed inside the storage bin 7. The water inlets of the first water pump 29 and the second water pump 9 are respectively located below the two low liquid level gauges 10, which can ensure that the liquid levels in the medicine dissolving tank and the storage bin 7 can drop below the two low liquid level gauges 10 to ensure the normal operation of the two low liquid level gauges 10. The first water pump 29 is responsible for transporting the uniformly concentrated medicine in the medicine dissolving tank 12 to the storage bin 7, and the second water pump 9 is responsible for outputting the medicine temporarily stored in the storage bin 7 to the position where the medicine needs to be added outside. The second water pump 9 has a water volume adjustment function and can control the output dose of the medicine. A recycling box 3 is provided on one side of the industrial robot 2, and the recycling box 3 is responsible for storing the empty powder packaging bags. After the medicine is added, the industrial robot 2 puts the empty powder packaging bags into the recycling box 3, which facilitates the later cleaning work of the workers. An electric control cabinet 8 is provided on one side of the storage bin 7, and the electric control cabinet 8 is responsible for receiving electrical signals and controlling the operation of each component.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5, Further, a hydraulic pump 24 is fixed to the top of the medicine dissolving tank 12. The first fixing frame 21 is fixed to the telescopic shaft of the hydraulic pump 24. The driver 28 and the rigid tube 22 with the second electromagnetic water valve 23 are both fixed to the first fixing frame 21. The first gear 26 meshes with the second gear 27 driven by the driver 28. The first gear 26 is fixedly sleeved on the bottom long rod part of the side-opening nozzle 20. The second gear 27 is fixed to the rotating shaft of the driver 28. The rigid tube 22 is sleeved outside the bottom of the long rod part of the side-opening nozzle 20. The side-opening nozzle 20 can rotate. The driver 28 can drive the side-opening nozzle 20 to rotate through the meshing of the first gear 26 and the second gear 27. The rigid tube 22 is connected to the hose 17. The hose 17 is connected to the water adding pipe 18 and the rigid tube 22. The side-opening nozzle 20 is located on one side of the bag-opening knife 15. The side-opening nozzle 20 is located at the middle position above the medicine adding port 13. After the bagged medicine powder 16 is cut by the bag-opening knife 15, the side-opening nozzle 20 is aligned with the middle position of the break. The side-opening nozzle 20 is vertically arranged and is located in the vertical plane where the blade of the bag-opening knife 15 is located. When the side-opening nozzle 20 works, it is located inside the packaging bag of the bagged medicine powder 16. The initial height of the side-opening nozzle 20 is lower than the height of the bag-opening knife 15 to avoid interference between the side-opening nozzle 20 and the moving bagged medicine powder 16. The rising height of the side-opening nozzle 20 is greater than the distance from the initial height of the side-opening nozzle 20 to the top of the bag-opening knife 15, ensuring that the side-opening nozzle 20 can enter the inside of the packaging bag from the break. The first gear 26, the second gear 27, and the driver 28 are all located inside the protective shell 25. The protective shell 25 is fixed to the first fixing frame 21 to prevent the gears from winding with the packaging bag when rotating. The first electromagnetic water valve 19 and the second electromagnetic water valve 23 independently control the on-off of their respective pipelines. The two pipelines do not affect each other, ensuring that both pipelines can be independently cut off and maintain the water flow. Electric control components such as the industrial robot 2 and the electric control cabinet 8 are all designed with explosion protection and can adapt to the complex conditions underground in the mine.

[0027] Working principle: The first agitator 11, the second agitator 6, and the second water pump 9 operate continuously. When the liquid level in the reserve bin 7 reaches the position where the low-level gauge 10 is located, the first water pump 29 works to transport the medicament in the medicament dissolving tank 12 to the reserve bin 7; when the liquid level in the reserve bin 7 reaches the position where the high-level gauge 5 is located, the first water pump 29 stops working. When the liquid level in the medicament dissolving tank 12 reaches the position where the low-level gauge 10 is located (if the first water pump 29 is working at this time, the first water pump 29 stops working and waits until the medicament adding and dissolving are completed before working again. The medicament between the low-level gauge 10 of the reserve bin 7 and the water inlet of the second water pump 9 is sufficient to complete the medicament adding and dissolving work of the medicament dissolving tank 12), the first electromagnetic water valve 19 opens the water supply pipe 18 to inject water into the medicament dissolving tank 12. At the same time, the bag gripper 4 grabs the bagged medicament powder 16 on the bagged medicament powder stack 1, raises the bagged medicament powder 16 to a height slightly lower than the upper edge of the blade of the bag opening knife 15, and moves it above the middle of the medicine adding port 13 of the medicament dissolving tank 12 along the parallel direction of the blade. At this time, the packaging bag of the bagged medicament powder 16 is cut by the bag opening knife 15, and the medicament powder falls into the medicament dissolving tank 12 through the medicine adding port 13. After most of the medicament powder falls into the medicament dissolving tank 12, the telescopic shaft of the hydraulic pump 24 extends to send the side-opening nozzle 20 into the packaging bag from the position of the break in the packaging bag. The second electromagnetic water valve 23 opens, and the driver 28 drives the side-opening nozzle 20 to rotate. The side-opening nozzle 20 sprays water and rotates to wash the residual medicament powder in the packaging bag, and the residual medicament powder is washed and falls into the medicine adding port 13. After the washing is completed, the second electromagnetic water valve 23 closes, the side-opening nozzle 20 stops working and returns to its original position. The bag gripper 4 on the industrial robot 2 transports the empty packaging bag above the recycling bin 3, releases the bag gripper 4, and the empty packaging bag falls into the recycling bin 3. When the liquid level in the medicament dissolving tank 12 reaches the position where the high-level gauge 5 is located, the first electromagnetic water valve 19 closes.
