Description

Sewage treatment equipment for ecological restoration of river course and river Technical Field The invention relates to the technical field of sewage treatment, in particular to a river ecological restoration sewage treatment device. Background In the field of river ecological restoration and sewage treatment, the traditional dredging equipment (such as cutter suction type equipment, trailing suction type equipment and the like) generally has the problem of poor adaptability to complex working conditions. When facing to high-viscosity and impurity-containing viscous sludge, the traditional suction port is extremely easy to be blocked, so that the operation is interrupted, and the dredging efficiency is seriously affected, and when facing to a hard or hardened riverbed, the equipment lacks an effective pretreatment means, so that the attachments are difficult to thoroughly strip, and the dredging is not thorough. In addition, the traditional equipment has single function, is difficult to maintain high-efficiency operation in the continuous change working conditions from hard to loose and from shallow to deep, and severely restricts the overall effect of ecological restoration of the river channel. In the prior art, the dredging operation generally adopts a separated operation mode of cutting and crushing before sucking and conveying. This mode causes a temporal and spatial dislocation of the cutting and aspiration links, and the energy (such as high-pressure water jet) generated by cutting is not effectively converted into aspiration power, but rather causes energy waste. Meanwhile, due to the lack of an intelligent self-adaptive adjusting mechanism, the equipment cannot automatically adjust the operation mode according to the real-time change of the hardness of the sludge, so that when the sludge with different hardness is faced, the cutting force is insufficient or the energy consumption is too high, and the energy cannot be efficiently utilized. The prior art faces a systematic technical problem of how to realize high-efficiency, continuous and self-adaption of dredging operation. This requires equipment that not only has a strong crushing capacity, but also has an anti-blocking suction structure, and an intelligent system capable of automatically switching operation modes according to the working conditions. However, the traditional mechanical structure design is often limited to a single function, which is easy to cause incomplete dredging and discontinuous operation, and cannot meet the high requirement of modern river ecological restoration on equipment adaptability. In view of the above, we propose a river course and river ecological restoration sewage treatment device. Disclosure of Invention The invention aims to provide river ecological restoration sewage treatment equipment for solving the technical problem that the pretreatment capacity is insufficient when hard sludge is treated in the prior art. In order to solve the technical problems, the invention provides the technical scheme that the river and river ecological restoration sewage treatment equipment comprises a ship body, a supporting arm with a telescopic structure, an adjusting frame and a silt sucking mechanism, wherein the silt sucking mechanism comprises a main body silt sucking component and a cutting component; The main body silt sucking component comprises a gun shell fixedly arranged on the adjusting frame, a silt sucking gun arranged in the gun shell and a plurality of hard rings; The silt sucking gun consists of a section of gun body and a section of telescopic pipeline with a rigid structure; The plurality of hard rings are sleeved in sequence from outside to inside and can axially slide along the gun shell, so that the lower end surfaces of the plurality of hard rings can be gathered to form a plane or unfolded to form a conical surface; The hard ring arranged on the inner side is sleeved on the surface of the gun body on the silt sucking gun; The lower surface of each hard ring is provided with an inclined surface and a suction inlet, the suction inlets are arranged on the inclined surfaces, and the bottoms of the hard rings are provided with stop blocks; When a plurality of hard rings are gathered, the inclined surface, the suction inlet and the stop block on the lower surface form a spiral channel; when a plurality of hard rings are unfolded, the plurality of hard rings can form a conical cavity through the inclined plane; When a plurality of hard rings are periodically switched between gathering and unfolding modes, the expansion and contraction actions of fish mouth ingestion can be formed; the cutting assembly comprises two groups of cutting modules; the invention solves the technical problems of low efficiency, easy blockage, high energy consumption and insufficient pretreatment capacity of the traditional river dredging equipment under complex working conditions by the aid of the unique structural design and function
