[0036] The working principle of the above embodiment is:

[0037] (1) First, fix the rope on the crane to the knot block 10 on the first shell 1, and then lower the device into the concrete through the crane. After the first shell 1 enters the concrete, the concrete will be poured into the feed pipe 21, and at the same time, the air inside the feed pipe 21 will be squeezed. After the air is squeezed, it will push the slider 222. The slider 222 slides in the feed pipe 21 and compresses the spring 221. The movement of the slider 222 drives the connecting rod 224 to move, and the connecting rod 224 drives the clamping plate 225 to move. When the device moves down to a certain position, the clamping plates 225 on both sides come into contact with the second shell 4 inside, supporting and protecting the second shell 4, thereby improving the stability and protection of the submersible slurry pump and avoiding damage.

[0038] (2) After the second housing 4 is well protected, the driving motor 511 is turned on. The driving motor 511 drives the rotating rod 512 to rotate. The rotating rod 512 drives the blade 514 to rotate. The high-speed rotation of the blade 514 forms a negative pressure in the extraction pipe 513, so that the concrete is drawn into the extraction pipe 513 and passes out through the material passage 515. While rotating, the rotating rod 512 also drives the driving gear 521 to rotate. The driving gear 521 drives the driven gear 522 to rotate. The driven gear 522 drives the rotating shaft 531 to rotate. The rotating shaft 531 drives the rotating block 532 to rotate. The rotating block 532 drives the stirring blade 533 to rotate. The stirring blade 533 crushes the hard blocks inside the concrete to loosen the concrete, thereby increasing the extraction concentration.
