Description

Technical Field

[0001] The invention relates to the technical field of urban environmental protection engineering, and in particular to underwater sludge cleaning equipment for urban environmental protection engineering construction. Background Art

[0002] Urban black and odorous water bodies seriously restrict the economic development of cities and the sustainable development of water ecosystems, and affect the quality of life and physical and mental health of urban residents. Carrying out urban water body dredging operations can effectively treat urban black and odorous water bodies. At present, there are still many deficiencies in the dredging technology for small and medium-sized urban water bodies. The rapid development of underwater robots provides a new idea for the development of an underwater dredging robot that can make up for these deficiencies.

[0003] For example, the Chinese authorized patent publication number CN201820263365.7 discloses “an underwater cleaning robot, comprising an upper computer and a lower computer, wherein the lower computer comprises a body, wherein a vertical power system is disposed in the body, and horizontal power systems are disposed on both sides of the body, wherein an adsorption drive system, a disc brush cleaning system and a camera are disposed on the top of the body, and a manipulator picking system is disposed on the bottom of the body”;

[0004] Another example is the Chinese authorized patent publication number CN201910083524.4, which discloses "a wheeled walking-propeller-propelled underwater cleaning robot, including a robot body and an above-water control device, wherein the robot body includes a carrier frame, a moving mechanism, an electrical compartment, an underwater propulsion device and a cleaning device";

[0005] These patents can enable the cleaning robot to move freely underwater and clean the target location; in the process of dredging urban water bodies, a suction dredging device is generally placed in front of the underwater robot; however, when the robot encounters larger or harder obstacles during its forward movement, it may get stuck and be unable to pass normally. At the same time, these obstacles may also cause certain damage to the spiral reamer, greatly affecting the normal development of underwater dredging operations; in addition, normal suction dredging may cause a low solid content in the sludge due to the inhalation of a large amount of water when no special environmental protection measures are adopted, which will greatly increase the difficulty of subsequent sludge treatment. Summary of the invention

[0046] Working principle: The driving motor 32 drives the rotating shaft 331 to rotate, and the two symmetrical spiral reamers 332 can concentrate the sludge on the inlet end of the filter screen 37, and then the sludge passes through the filter screen 37 and is sucked out by the sludge duct 5; this greatly improves the solid content of the sucked out sludge; at the same time, the rotating shaft 331 drives the first gear 3412 to rotate, which also causes the third gear 3414 to rotate, so that the second gear 3413 and the fourth gear 3415 rotate synchronously, which also causes the drum sleeve 335 to drive all the connecting discs 333 to rotate, and then all the special-shaped reamers 336 rotate. The special-shaped reamers 336 can damage obstacles. If the obstacles are not easy to destroy, they can also act on the obstacles to achieve climbing over them, so as to prevent the obstacles from hindering the dredging work.

[0047] Embodiment 2:

[0048] In Example 1, the filter screen 37 will filter the sludge. As the dredging work continues, a large amount of large mud will accumulate on the outer layer of the filter screen 37, which may clog the filter holes of the filter screen 37, thus causing the filter screen 37 to fail to achieve the filtering effect and the dredging work to fail to continue;

[0049] Reference Figure 1-6As another preferred embodiment of the present invention, the difference from Embodiment 1 is that the silting module 3 also includes a cleaning mechanism 38, which includes a mounting seat 382, ​​a brush plate 383, a driving member 384 and two guide rails 381; the two guide rails 381 are fixedly mounted in parallel on the inner side of the outer cover shell 31 and are respectively located at the two ends of the filter screen 37, the two ends of the mounting seat 382 are respectively slidably mounted on the corresponding guide rails 381, the brush plate 383 is fixedly mounted on the inner side of the mounting seat 382 and can be fitted with the outer surface of the filter screen 37; the driving member 384 is mounted on the outer side of the mounting seat 382; the brush plate 383 is used to clean the outer surface of the filter screen 37.

[0050] The driving member 384 includes a fixed seat 3841, an incomplete gear 3843, a connecting shaft 3844 and two racks 3842. The fixed seat 3841 is fixedly mounted on the outer side of the mounting seat 382. The mounting seat 382 is an annular structure. The two racks 3842 are respectively fixedly mounted on two opposite inner walls of the mounting seat 382. The incomplete gear 3843 is rotatably mounted in the outer cover shell 31 through the connecting shaft 3844. The incomplete gear 3843 is located between the two racks 3842 and can mesh with any one of the racks 3842. The incomplete gear 3843 can drive the corresponding rack 3842 to move.

The first sprocket 3421 is coaxially fixedly connected to the fourth gear 3415, and the second sprocket 3422 is fixedly installed at the end of the connecting shaft 3844. The first sprocket 3421 and the second sprocket 3422 are connected by a chain transmission.

[0052] Working principle: The rotating shaft 331 is driven by the driving motor 32 to rotate, and the two symmetrical spiral reamers 332 can concentrate the sludge on the inlet end of the filter screen 37; at the same time, the rotating shaft 331 drives the first gear 3412 to rotate, which also causes the third gear 3414 to rotate, so that the second gear 3413 and the fourth gear 3415 rotate synchronously, which also causes the rotating drum sleeve 335 to drive all the connecting discs 333 to rotate, and then all the special-shaped reamers 336 to rotate;

[0053] When the fourth gear 3415 rotates, it drives the first sprocket 3421 to rotate. Under the transmission of the chain, the second sprocket 3422 and the connecting shaft 3844 rotate synchronously, thereby rotating the incomplete gear 3843; when the incomplete gear 3843 is engaged with one of the racks 3842, the fixed seat 3841 drives the mounting seat 382 to move as a whole; when the incomplete gear 3843 is engaged with the other rack 3842, the fixed seat 3841 drives the mounting seat 382 to move in the opposite direction as a whole; finally, the fixed seat 3841 can realize reciprocating movement, so that the brush plate 383 repeatedly cleans the filter screen 37, thereby preventing the filter screen 37 from being blocked and affecting the dredging work.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
