[0028] As shown in Figure 4, a set of scrapers 120 are fixedly connected to the outer wall of the stirring rod 119. The inner wall of the scraper 120 is slidably connected to the inner wall of the mixing tank 110.

[0029] As shown in Figure 3, a second centrifugal pump 111 is fixedly connected to the outer wall of the mixing tank 110, and a telescopic hose 112 is fixedly connected to the output end of the second centrifugal pump 111.

[0030] As shown in Figure 3, a groove 113 is provided on the inner wall of the base 101. A slider 117 is slidably connected to the inner wall of the groove 113.

[0032] The usage and working principle of this device are as follows: First, the horizontal position of the drill bit 115 can be flexibly adjusted by the linkage between the sliding groove 113 on the inner wall of the base 101, the slider 117, and the electric push rod 121. After positioning, the bolt 116 is screwed into the corresponding threaded hole to fix the slider 117 and ensure the stability of the drilling process. Subsequently, the second servo motor 114 drives the drill bit 115 to rotate at high speed, while the electric push rod 121 precisely controls the feed rate to perform directional drilling on the well wall cracks, providing a precise channel for subsequent injection of plugging slurry. After drilling is completed, the plugging materials such as bentonite slurry and nano silica slurry in the storage tank 107 enter the conveying stage. The operator starts the first centrifugal pump 106 through the control panel of the PLC controller 102 to pump the materials in the storage tank 107 to the mixing tank 110 through the conveying pipeline 104. The Doppler ultrasonic flow meter 105 on the pipeline is based on Doppler... The system detects the ultrasonic frequency shift reflected by solid particles in the slurry in real time, calculates the average flow velocity of the fluid, and obtains the flow rate to ensure accurate and controllable delivery. Inside the mixing tank 110, the first servo motor 118 drives the stirring rod 119 to rotate, and the outer wall scraper 120 simultaneously scrapes the tank wall to prevent material adhesion and promote uniform mixing of the plugging material and the liquid. The operator can observe the stirring status through the transparent plate 103. The PLC controller 102 uniformly controls the motor start / stop and stirring parameters to ensure the mixing quality of the slurry. After stirring, the telescopic hose 112 is inserted into the borehole, and the second centrifugal pump 111 is started to accurately pump the stirred plugging slurry to the crack location through the telescopic hose 112 to complete the plugging operation. The entire process is automated and coordinated by the PLC controller 102, from drilling, material conveying, stirring to pumping and plugging, greatly reducing manual intervention and significantly improving work efficiency and accuracy.
[0033] The PLC controller 102, Doppler ultrasonic flow meter 105, first centrifugal pump 106, second centrifugal pump 111, first servo motor 118, second servo motor 114, and electric actuator 121 used in this application are all common conventional equipment on the market and are well known to those skilled in the art.
