during operation, when the driving screw 7 controls the water guide sealing block 12 to move upwards, the driving bevel gear 39 rotates along with the rotation of the driving screw 7, the driven bevel gear 38 rotates along with the rotation of the driving bevel gear 39, and then the driven screw 37 is driven to rotate, because the second piston plate 36 is in threaded connection with the driven screw 37, the second piston plate 36 moves leftwards in the hydraulic chamber 35 to extrude the internal hydraulic oil, the pressure is transmitted to the bottom of the hydraulic cylinder 33 through the hydraulic pipe 34, so that the movable hydraulic rod 32 is pushed to move upwards, and the first mesh plate 54 is pushed to move upwards, so that the movable units 53 are further pushed to move upwards, and the slope protection block in the extrusion sample placement component 5 moves upwards, so that the slope protection block can be conveniently taken out, and the detection efficiency is effectively improved.

The working principle is as follows:

when the device works, the slope protection block is placed in the sample placing assembly 5 for detection, the slope protection block is placed at the upper ends of the movable units 53, the upper rods 531 at the lower end of the slope protection block penetrate through the positioning plate 52 to move downwards under the influence of the gravity of the slope protection block, the lower rods 532 are fixedly connected to the first mesh plate 54, the upper rods 531 move downwards, the upper ends of the lower rods 532 enter the inner parts of the upper rods 531, the side water guide grooves 533 move downwards along with the movement of the upper rods 531, when the positioning plate 52 is contacted, the side water guide grooves 533 are communicated with the upper ends and the lower ends of the positioning plate 52, so that the conduction of water flow leaked from the slope protection block is facilitated, the leaked water enters the lower liquid storage pipe 4 through the first mesh plate 54 and the water guide holes 55, the cross sections of the upper rods 531 are hexagonal, can be mutually attached and can independently move, and the slope protection blocks with different sizes and shapes can be well fixed and sealed, the detection to the revetment block is comparatively convenient and fast, it is rotatory to drive screw 7 through driving motor 6, because drive screw 7 and connecting strip 10 threaded connection, through the steerable connecting strip 10 of rotation of drive screw 7 and reciprocate along guide bar 9, through the sealed piece 12 of the steerable water guide of control frame 11 reciprocates, when placing subassembly 5 with the sample and contacting, can treat the revetment block ring side that detects and fix and seal, the condition of avoiding leaking takes place, and then improve the accuracy of testing result.

The opening of the water inlet pipe joint 14 is controlled through the first control valve 15, water flow is guided into the upper liquid storage pipe 13 through the water inlet pipe joint 14, the movable sealing block 30 can be pushed to move upwards along with the gradual increase of the water flow as the density of the movable sealing block 30 is smaller than that of the water flow, and the movable sealing block 30 cannot move when being blocked when being contacted with the fixed air guide block 28, so that the water flow can be prevented from entering the pressurizing chamber 18, the air guide through hole 29 is arranged, the conduction of air can be facilitated, the internal pressure of the upper liquid storage pipe 13 can be changed conveniently, and the detection result accuracy of the detector is improved; when detecting the slope protection piece, the pressurization chamber 18 constitutes sealed annular structure with last liquid storage pipe 13 and lower liquid storage pipe 4, through the steerable first piston board 21 rebound of electricity liquid push rod 20, pressurizes the inside water of last liquid storage pipe 13, because second mesh board 19 is ventilative structure, when first piston board 21 rebound, can exert the negative pressure to the downside of slope protection piece through lower liquid storage pipe 4 to further improve detection efficiency.

The control chamber 22 moves along with the movement of the first piston plate 21, the pressure on the upper side of the first piston plate 21 is the same as the pressure in the upper liquid storage pipe 13, the electromagnet 23 is conducted, the electromagnet 23 and the permanent magnet 24 repel each other, at the moment, the repulsion force, gravity and pressure from the control rod 25 on the permanent magnet 24 keep balance, when the pressure in the upper liquid storage pipe 13 reaches the required air pressure, the control rod 25 moves downwards under the influence of the internal air pressure, the permanent magnet 24 is pushed to move downwards, the conducting strip 26 moves along with the movement of the permanent magnet 24 and is separated from the electric connector 27, the electric hydraulic push rod 20 is powered off, and pressurization is stopped; along with the continuous leakage of water flow, the internal pressure is reduced, the repulsive force between the permanent magnet 24 and the electromagnet 23 pushes the permanent magnet 24 and the control rod 25 to move upwards, the conducting strip 26 is in contact with the electric connector 27, the electro-hydraulic push rod 20 is electrified to push the first piston plate 21 to move upwards continuously, so that the water pressure is kept stable, the operation is convenient and fast, the preset water pressure can be changed quickly by changing the current of the electromagnet 23, and the operation is convenient and fast; after the detection is finished, the second control valve 17 is opened, and the leaked water is discharged through the lower liquid storage pipe 4 and the liquid discharge pipe 16, so that the water is convenient to recover.

When the slope protection block is taken out, firstly, when the driving screw 7 controls the water guide sealing block 12 to move upwards, the driving bevel gear 39 rotates along with the rotation of the driving screw 7, the driven bevel gear 38 rotates along with the rotation of the driving bevel gear 39, and then the driven screw 37 is driven to rotate, because the second piston plate 36 is in threaded connection with the driven screw 37, the second piston plate 36 moves leftwards in the hydraulic chamber 35 to extrude the internal hydraulic oil, the pressure is transmitted to the bottom of the hydraulic cylinder 33 through the hydraulic pipe 34, so that the movable hydraulic rod 32 is pushed to move upwards, the first mesh plate 54 is pushed to move upwards, the movable units 53 are further pushed to move upwards, the slope protection block in the extrusion sample placement component 5 moves upwards, and therefore, the slope protection block can be conveniently taken out, the operation is convenient and fast, and the detection efficiency is effectively improved.
