Description

Technical Field

[0001] This utility model relates to the field of dredging equipment technology, specifically a device for dredging and cleaning silt from water conservancy engineering waterways. Background Technology

[0002] "Dredging" refers to clearing and deepening waterways such as rivers and ports. By removing sediments such as mud, rocks, and garbage from the bottom of the water, the water is widened and deepened to ensure the normal operation of functions such as navigation, flood discharge, and irrigation.

[0003] The existing Chinese patent publication number CN222390536U, entitled "A Channel Dredging Silt Cleaning Device," explicitly states in its abstract that "This utility model relates to the field of dredging equipment technology, specifically to a channel dredging silt cleaning device, including a hull, a silt guide pipe, a conveying unit, and a separation component. The separation component includes a support frame, a box, a first cylinder, a pressing plate, a discharge pipe, a first solenoid valve, and a second solenoid valve. The right side of the box has multiple water-permeable holes. Opening the second solenoid valve allows silt to enter the box through the silt guide pipe. When the box is full of silt, the second solenoid valve is closed, and then the first cylinder pushes the pressing plate to move, compressing the silt inside the box and causing the water inside to be discharged through the multiple water-permeable holes. After the water is discharged, the first cylinder drives the pressing plate back to its original position, and then the first solenoid valve is opened, allowing the silt to be discharged from the discharge pipe. This removes water from the silt, thereby increasing the silt carrying capacity of the hull, reducing the number of silt cleaning operations on the hull, and lowering the cost of river dredging."

[0004] However, in this technology, after the sludge inside the cylinder enters the mud guide pipe, the sludge needs to flow naturally to the bottom box. This is not only slow, but also prone to clogging the mud guide pipe. Furthermore, after the sludge is squeezed in the box, it may stick together. If there is a lot of sludge inside, and the thickness of the sticky sludge is wider than the width of the discharge pipe, it may cause the sludge inside to be difficult or even impossible to discharge, thus affecting its use. Utility Model Content

[0005] The purpose of this utility model is to provide a device for cleaning silt from waterway dredging in water conservancy projects, so as to solve the problems of silt blockage and inconvenience or even inability to discharge silt mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dredging and silt removal device for water conservancy engineering waterways includes a hull, a cylinder, and a silt guide pipe.

[0026] Please refer to Figures 1-4 This utility model discloses a dredging and silt removal device for water conservancy engineering channels, comprising a hull 1, a cylinder 11, and a silt guide pipe 12. The hull 1 and cylinder 11 are the same hull and cylinder structures as described in the prior art patent. The internal structure of the cylinder 11 is the same as that described in the prior art patent. The silt guide pipe 12 is connected to the top of the cylinder 11, allowing silt to be transported to the silt guide pipe 12. The silt guide pipe 12 is equipped with a spiral blade 13 inside. An installation box 2 is provided at the bottom of the silt guide pipe 12, which is connected to the discharge point of the silt guide pipe 12. A motor 14 is provided on one side of the silt guide pipe 12, and the drive shaft of the motor 14 is connected to the spiral blade 13. A solenoid valve 21 is provided at the discharge point of the silt guide pipe 12, allowing the motor 14 to drive the spiral blade 13 to rotate, thereby ensuring the silt in the silt guide pipe 12 is transported to the installation box 2. The solenoid valve 21 can be used to open and close the discharge point of the silt guide pipe 12.

[0027] The installation box 2 is equipped with an extrusion assembly, which includes an extrusion ring 24. An outlet 22 is provided on the outer side of the upper part of the installation box 2, and a guide groove 23 is provided at the bottom of the outer side of the outlet 22. An installation cover 41 is detachably installed at the bottom of the installation box 2. An extrusion plate 43 is provided on the upper part of the installation cover 41. A fourth electric push rod 44 is provided on the inner side of the installation cover 41. The telescopic end of the fourth electric push rod 44 is connected to the extrusion plate 43. That is, the extrusion plate 43 is pushed upward by the fourth electric push rod 44, thereby squeezing the sludge inside the installation box 2. The squeezed water is discharged through the outlet 22 and guided through the guide groove 23. The solenoid valve 21 is closed during squeezing. A first electric push rod 25 is provided on both sides of the top of the mud guide pipe 12. The telescopic end of the first electric push rod 25 is connected to the extrusion ring 24. After the water is squeezed out, the installation cover 41 is opened. At this time, the extrusion ring 24 is pushed by the first electric push rod 25 to discharge the sludge inside, thereby effectively avoiding sludge blockage and failure to discharge.

[0028] A sliding frame 33 is provided on the hull 1. A sliding component 34 is slidably arranged inside the sliding frame 33. A second electric push rod 35 is provided on the rear side of the sliding frame 33. The second electric push rod 35 is connected to the sliding component 34. A third electric push rod 4 is provided on the sliding component 34. The telescopic end of the third electric push rod 4 is connected to the mounting cover 41. A sealing ring 42 is provided on the mounting cover 41. That is, by pushing the mounting cover 41 with the third electric push rod 4, the mounting cover 41 is installed at the bottom of the mounting box 2, thereby closing the bottom of the mounting box 2. The sealing ring 42 is attached to the bottom of the mounting box 2, thereby achieving a sealing effect and preventing water from flowing out. Conversely, the bottom of the mounting box 2 is opened, and the second electric push rod 35 drives the sliding frame 33 to move backward, that is, drives the mounting cover 41 to move backward, thereby fully opening the bottom of the mounting box 2.

[0029] A receiving slot 15 is placed below the sliding frame 33, which is located directly below the mounting box 2 to receive the pushed-out sludge. A rotating ring 3 is rotatably installed on the outer side of the top of the mounting box 2. The rotating ring 3 is locked on the outer side of the top of the mounting box 2 and rotates. A hexagonal rod 31 is slidably installed on one side of the bottom of the rotating ring 3. An insert block 32 is installed on the hexagonal rod 31. The insert block 32 is installed and removed in the water outlet 22. That is, by rotating the rotating ring 3, the insert block 32 is connected to different water outlets 22. By pressing the hexagonal rod 31 on the outside, different water outlets 22 can be cleaned through the insert block 32.

[0030] The working principle of this utility model is as follows: Sludge is conveyed to the guide pipe 12 through the cylinder 11. The spiral blades 13 are rotated by the motor 14, ensuring the sludge is conveyed in the guide pipe 12 and avoiding blockages or slow conveying. The sludge is then conveyed to the installation box 2. When a large amount of sludge accumulates inside the installation box 2, the discharge point of the guide pipe 12 is closed by the solenoid valve 21. The extrusion plate 43 is pushed upwards by the fourth electric push rod 44, thereby squeezing the sludge inside the installation box 2. The squeezed water is discharged through the outlet 22 and flows through the guide channel 2. 3. After the water is squeezed out, the installation cover 41 is opened by the third electric push rod 4, and the sliding frame 33 is moved backward by the second electric push rod 35, which in turn moves the installation cover 41 backward, thus fully opening the bottom of the installation box 2. At this time, the extrusion ring 24 is pushed by the first electric push rod 25 to discharge the sludge inside, thus effectively avoiding sludge blockage and failure to discharge. By rotating the rotating ring 3, the insert block 32 is connected to different water outlets 22. By pressing the hexagonal rod 31 on the outside, the insert block 32 can be used to clean different water outlets 22.
