Technical Field

[0001] The invention relates to the technical field of sludge solidification, in particular to an in-situ sludge solidification device. Background Art

[0002] Silt solidification, a technique that involves adding a certain amount of admixtures to silt to improve its physical and mechanical properties to meet the needs of various projects, falls under the category of soil solidification. Silt solidification is widely used in practice due to its simple process, high efficiency, and reasonable price.

[0003] The existing in-situ sludge solidification device still has certain shortcomings during actual use: the existing solidification device has a large mixing head, and when the excavator drives the solidification device to move under the silt, it lacks a self-locking structure. It is necessary to constantly control the excavator's lever arm to keep the solidification device in one position, which is energy-consuming. In addition, the solidification device may sink in the silt, causing the excavator to be unstable in the front and back. Based on the shortcomings of the existing technology, the present invention designs an in-situ sludge solidification device. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This in-situ silt solidification device uses a floating structure. During the silt solidification process, the mounting arm is moved to the bottom of the silt by the excavator's lever arm. At this time, by simultaneously starting the four first motors, the output shafts thereof drive the first screw to rotate, thereby enabling the four first threaded blocks to move horizontally on the outer surface of the first screw. Since the first hinged rod is hinged to the second hinged rod through the hinged seat, the first hinged rod can push the second hinged rod to change its angle when the first threaded block moves, thereby enabling the four air bags to move to the silt surface. At this time, the air inlet is driven by four air pumps to draw air from the outside. After the air bags are inflated, the mounting arm can float on the top of the silt, thereby achieving the purpose of floating the device and preventing it from sinking, thereby improving the stability of the device during operation.

[0017] 2. This in-situ sludge solidification device uses a mobile structure. When the floating structure floats and supports the mounting arm, the second motor is driven so that its output shaft drives the second screw to rotate. Due to the drive of the limiting rods on both sides, the second threaded block can move horizontally up and down on the outer surface of the second screw, thereby allowing the second threaded block to drive the floating structure to move on the outer surface of the mounting arm, thereby adapting to different stirring depths and improving the flexibility of the device.

[0018] 3. This in-situ silt solidification device uses a resistance sensor and a detection structure. When the installation arm reaches the inside of the silt, the resistance sensor can detect the hardness and density of the silt solidification. The electric push rod drives one end of the telescopic rod to drive the transparent cover to extend from the inside of the installation arm. The controller can control the monitoring probe to inspect the solidification situation inside the silt. At the same time, the transparent cover can protect the monitoring probe from being hit and damaged by stones in the silt. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figure 1-6The movable structure 4 includes a second motor 41 and two limiting rods 43. A second screw 42 is fixedly mounted on one end of the output shaft of the second motor 41 and is rotatably connected to the interior of the first inner groove 3. The two limiting rods 43 are fixed to the interior of the first inner groove 3. A second threaded block 44 is threadedly mounted on the outer surface of the second screw 42 and is slidably connected to the limiting rods 43. Four extension plates 45 are fixedly mounted on the outer surface of the second threaded block 44. The four extension plates 45 are fixedly connected to the four sets of first support plates 21.

[0031] By driving the second motor 41, its output shaft drives the second screw 42 to rotate. Due to the drive of the limiting rods 43 on both sides, the second threaded block 44 can move horizontally up and down on the outer surface of the second screw 42, thereby enabling the second threaded block 44 to drive the floating structure 2 to move on the outer surface of the mounting arm 1, thereby adapting to different stirring depths.

[0032] See also Figure 1-4 A second inner groove 5 is defined at the top of the mounting arm 1 and is fixedly connected to the second motor 41. Stirring structures 6 are fixedly mounted on both sides of the outer surface of the mounting arm 1. The two stirring structures 6 include fixed frames 61. Mounting plates 62 are fixedly mounted within the two fixed frames 61, and third motors 63 are fixedly mounted on one side of the outer surfaces of the two mounting plates 62.

Detection structure 8 includes an electric push rod 81, with a transparent cover 82 fixedly mounted on one end of the telescopic rod of the electric push rod 81.

The controller 83 is fixedly connected to the telescopic rod of the electric push rod 81, and a monitoring probe 84 is fixedly mounted on one side of the controller 83 and is disposed within the transparent cover 82.

[0035] When the mounting arm 1 reaches the inside of the silt, the hardness and density of the solidified silt can be detected by the resistance sensor 7. The electric push rod 81 is driven to cause one end of the telescopic rod to drive the transparent cover 82 to extend from the inside of the mounting arm 1. The monitoring probe 84 can be controlled by the controller 83 to inspect the solidification condition of the silt. At the same time, the transparent cover 82 can protect the monitoring probe 84 from being hit and damaged by stones in the silt.

[0036] Working principle: when an in-situ silt solidification device is used, the installation arm 1 is first moved to the bottom of the silt by the excavator arm. At this time, the four first motors 23 are started at the same time to make their output shafts drive the first screw 24 to rotate, thereby making the four first threaded blocks 25 move horizontally on the outer surface of the first screw 24. Since the first hinged rod 26 is hinged to the second hinged rod 29 through the hinge seat 27, the first hinged rod 26 can push the second hinged rod 29 to change its angle when the first threaded block 25 moves, thereby making the four air bags 212 move to the surface of the silt. At this time, the air inlet 211 is driven by the four air pumps 210 to suck air from the outside, so that the air bag 212 is inflated and the installation arm 1 can float on the top of the silt. At the same time, the second motor 41 is driven to make its output shaft Drive the second screw 42 to rotate. Due to the drive of the limit rods 43 on both sides, the second threaded block 44 can move horizontally up and down on the outer surface of the second screw 42, thereby allowing the second threaded block 44 to drive the floating structure 2 to move on the outer surface of the mounting arm 1, thereby adapting to different stirring depths. At this time, the output shaft of the third motor 63 drives the stirring head 64 to rotate, thereby stirring the silt. Finally, the hardness and density of the solidified silt can be detected by the resistance sensor 7. The electric push rod 81 is driven to drive one end of the telescopic rod to drive the transparent cover 82 to extend from the inside of the mounting arm 1. The monitoring probe 84 can be controlled by the controller 83 to observe the internal solidification situation of the silt. At the same time, the transparent cover 82 can protect the monitoring probe 84 from being hit and damaged by stones in the silt.
