DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 A device for isolating and covering contaminated soil and groundwater in situ comprises a base plate 1, a plurality of pulleys 2 are fixedly mounted on the bottom wall of the base plate 1, a support frame 3 is fixedly mounted on the upper end surface of the base plate 1, a screw 5 is rotatably mounted on the upper end surface of the support frame 3 through a lifting frame 4, a first motor 6 connected to the screw 5 is fixedly mounted on the upper end surface of the lifting frame 4, a movable plate 7 is threadedly mounted on the outer wall of the screw 5, and the bottom wall of the movable plate 7 is fixedly connected to a plug plate 9 through a connecting mechanism, and the connecting mechanism comprises two connecting rods 8 fixedly mounted on the bottom wall of the movable plate 7, and the ends of the two connecting rods 8 are fixedly connected to the upper end surface of the plug plate 9.

[0023] A connecting plate 10 is fixedly installed on the outer wall of the insert plate 9, and a cylinder 11 is fixedly installed on the inner wall of the connecting plate 10. The telescopic end of the cylinder 11 is fixedly connected to a clamping plate 12, and an anti-slip pad 13 is fixedly installed on the inner wall of the clamping plate 12. The anti-slip pad 13 is made of rubber. The rubber material has good elasticity and softness, which enables it to form a closer contact between the surface and the object, thereby increasing friction and improving the friction coefficient. A winding roller 15 is rotatably installed on the upper end surface of the base plate 1 through a first supporting mechanism. The first supporting mechanism includes two first supporting plates 14 fixedly installed on the upper end surface of the base plate 1. The winding roller 15 is rotatably installed between the two first supporting plates 14. A guide roller 17 is rotatably installed on the upper end surface of the base plate 1 through a second supporting mechanism. The second supporting mechanism includes two second supporting plates 16 fixedly installed on the upper end surface of the base plate 1, and the guide roller 17 is rotatably installed between the two second support plates 16.

[0024] The bottom wall of the support frame 3 is fixedly connected to the moving frame 19 through a lifting mechanism. The lifting mechanism includes an electric push rod 18 fixedly installed on the bottom wall of the support frame 3. The telescopic end of the electric push rod 18 is fixedly connected to the upper end face of the moving frame 19. A reciprocating screw 20 is rotatably installed inside the moving frame 19. A second motor 21 connected to the reciprocating screw 20 is fixedly installed on the outer wall of the moving frame 19. A screw sleeve 23 is threadedly installed on the outer wall of the reciprocating screw 20 through a limiting mechanism. The limiting mechanism includes a limiting rod 22 fixedly installed inside the moving frame 19. The limiting rod 22 slides through the screw sleeve 23. The limiting rod 22 can limit the screw sleeve 23 so that the screw sleeve 23 can only move axially along the outer wall of the reciprocating screw 20. A connecting plate 24 is fixedly installed on the bottom wall of the screw sleeve 23, and a blade 25 is fixedly installed on the bottom wall of the connecting plate 24.

[0025] When the present invention is in use, the bottom plate 1 can be conveniently moved by multiple pulleys 2. Before barrier covering, the HDPE film can be first wound on the outer wall of the winding roller 15. When barrier covering is performed, the HDPE film can be pulled to be laid on the outer wall of the guide roller 17, and then the HDPE film can be pulled so that its end is fitted with the outer wall of the inserting plate 9. Then the cylinder 11 can drive the clamping plate 12 to move, so that the clamping plate 12 can clamp and fix the HDPE film through the anti-slip pad 13. The anti-slip pad 13 can increase the friction with the outer wall of the HDPE film, thereby increasing the effect of its clamping and fixing, and the anti-slip pad 13 can also avoid damage to the HDPE film. In an emergency, the first motor 6 drives the screw 5 to rotate. When the screw 5 rotates, it can drive the inserting plate 9 to move downward through the cooperation of the movable plate 7 and the connecting rod 8, thereby allowing the inserting plate 9 to drive the clamped and fixed HDPE film to move underground, thereby completing the barrier covering process.

[0026] When the HDPE film completes the barrier covering, the electric push rod 18 can drive the movable frame 19 to move downward, so that the blade 25 can contact the surface of the HDPE film. Then the second motor 21 drives the reciprocating screw 20 to rotate, and the reciprocating screw 20 drives the screw sleeve 23 to move through the cooperation with the limit rod 22. The screw sleeve 23 then drives the blade 25 to move back and forth through the cooperation of the connecting plate 24, so that the blade 25 can completely cut the HDPE film, thereby ensuring the integrity of the HDPE film and preventing its damage from affecting the use effect.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
