Description

Technical Field

[0001] The present invention relates to the technical field of silt removal devices, and in particular to a silt removal device for environmental protection engineering construction. Background Art

[0002] Environmental protection projects refer to projects specifically designed for environmental protection. They are based on a set of envisioned goals, apply relevant scientific knowledge and technical means, and address environmental pollution issues through the organized activities of a group of people. When conducting environmental protection design and construction, it is necessary to dredge rivers and other places to prevent silt sedimentation from affecting the design and construction of environmental protection projects.

[0003] Those skilled in the art have conducted research and improvements on this. For example, a desilting device for water conservancy projects proposed in application number CN202010991289.3 uses a screw to drive the mounting plate to move up and down, which can adjust the depth of the suction pipe. The scissor mechanism drives the suction pipe to move through the mounting sleeve, which can adjust the distance between adjacent suction pipes to adapt to canals of different widths. However, this technical solution has many defects, and the following defects still exist:

[0004] 1. Limited crushing capacity: The stirring rake can only push away debris, but cannot completely crush large impurities, and cannot fundamentally solve the risk of blockage;

[0005] 2. The depth adjustment range is limited; the suction pipe depth is adjusted by the screw rod, and the overall working stroke is limited, which makes it difficult to meet the needs of different water areas;

[0006] 3. Lack of dehydration process: sludge is directly collected in the frame without integrated dehydration treatment, which results in a heavy burden on subsequent disposal;

[0007] 4. Lack of remote control: The entire equipment is placed on board and its operation requires close manual intervention, which has a low safety factor.

[0008] To this end, we proposed a dredging device for environmental protection engineering construction. Summary of the Invention

The output end of the dredge pump 1001 is connected to a bellows 1002, and the overall length is adjustable to avoid interference with the depth adjustment of the dredging work. The top of the inner cavity of the protective cover 10 is connected to a steering motor 1003, and the output end of the steering motor 1003 is connected to a bevel gear 1004. A hollow tube 1005 is rotatably connected between the protective cover 10 and the dredging shell 11, and the upper part of the outer wall of the hollow tube 1005 is connected to a bevel gear ring 1006. The bevel gear ring 1006 is meshed with the bevel gear 1004, and the lower part of the outer wall of the hollow tube 1005 is connected to the driving wheel 1007. The outer wall of the protective cover 10 is circumferentially connected with a plurality of counterweight blocks 1008 to ensure that the dredging structure can smoothly descend into the silt area. The bottom center of the dredging shell 11 is connected to the mud suction cover 1101, and the mud suction cover 1101 is connected to the input end of the mud pump 1001 with a mud pipe 1009. The mud pipe 1009 runs through the hollow tube 1005 and does not affect the rotation of the hollow tube 1005 during dredging.

[0055] A plurality of annular columns 1102 are rotatably connected in the dredging shell 11, and a driven wheel 1103 is connected to the outer wall of the annular column 1102, and the driven wheel 1103 is meshedly connected to the driving wheel 1007.

The upper end of the vertical shaft 1104 is rotatably connected to the lifting block 1106, and an L-shaped rod 1051 is connected to the middle part of the outer wall of the hollow tube 1005. The vertical end of the L-shaped rod 1051 is connected to the wear-resistant ball 1052, and the wear-resistant ball 1052 abuts the upper end surface of the lifting block 1106.

[0056] The bottom surfaces of multiple lifting blocks 1106 are arranged in a ring-shaped structure, and the upper ends of the lifting blocks 1106 are arranged in a wavy structure.

The guide bar 1141 is slidably connected in the limiting groove 1121 to ensure that the vertical shaft 1104 and the annular column 1102 rotate synchronously.

[0057] The specific implementation of this embodiment is as follows:

[0058] When the device is performing dredging work in the water area, the lateral floating platform 3 and the tail floating platform 5 float on the water surface. The PLC controller 13 uses a wireless communication module to connect to a mobile terminal, and can remotely control the operation of the equipment on shore or on board, thereby improving the safety factor of the staff. The winding drum 7 is controlled by the winding motor 6 to rotate forward and reverse, and the scale rope 8 can be wound and unwound, thereby adjusting the water depth of the protective cover 10 and the dredging shell 11. A counterweight block 1008 is provided to overcome the buoyancy effect. After reaching the working position, the steering motor 1003 and the mud pump 1001 are started, and the silt enters the mud pipe 1009 from the mud suction cover 1101 and is then introduced into the bellows 1002.

[0059] By meshing the bevel gear 1004 with the bevel gear ring 1006, the hollow tube 1005 can drive the driving wheel 1007 to rotate, and the driving wheel 1007 is meshed with the driven wheel 1103 to rotate the annular column 1102 in the dredging shell 11. The guide strip 1141 and the limit groove 1121 cooperate to guide and ensure that the vertical shaft 1104 and the annular column 1102 rotate synchronously. After the vertical shaft 1104 rotates, the crushing cutter 1105 cuts and crushes the impurities around the mud suction cover 1101 to prevent large impurities from clogging the pipeline.

[0060] The bottom surface of the lifting block 1106 is in a ring shape and the upper end is in a wavy structure. When the L-shaped rod 1051 rotates with the hollow tube 1005, the wear-resistant head 1052 fits into the upper end of the lifting block 1106, and is elastically reset by the spring rod 1161. As the contact position between the wear-resistant head 1052 and the lifting block 1106 changes, the lifting block 1106 drives the vertical shaft 1104 to rise and fall, which can increase the working range of the crushing cutter 1105 and ensure the impurity crushing effect.

The sludge impurities remain on the upper surface of the water filter plate 1205. The conveying motor 408 drives the conveying shaft 403 to rotate, and the teeth of the incomplete bevel gear ring 405 are periodically engaged.
