Buried culvert desilting system

Abstract

The invention discloses a buried culvert desilting system, and belongs to the technical field of desilting equipment. The buried culvert desilting system comprises a scraper bucket and is characterized in that the buried culvert desilting system further comprises a main traction winch, an auxiliary traction winch, a main supporting frame, an auxiliary supporting frame, a main traction steel wire rope, an auxiliary traction steel wire rope, a PLC, a frequency converter and a displayer; a main proximity switch is fixed to the bottom of the main supporting frame, and an auxiliary proximity switchis fixed to the bottom of the auxiliary supporting frame; one end of the main traction steel wire rope is connected with the main traction winch, and the other end of the main traction steel wire rope is connected with the scraper bucket; one end of the auxiliary traction steel wire rope is connected with the auxiliary traction winch, and the other end of the auxiliary traction steel wire rope isconnected with the scraper bucket; and the scraper bucket is driven by the main traction winch and the auxiliary traction winch to do reciprocating motion in a culvert in the length direction of theculvert. Through the buried culvert desilting system, the desilting operation efficiency can be effectively improved, the operation process is visualized, thus, the operation situation of the interiorof the underground culvert can be monitored in real time, and deposits in the underground culvert can be advantageously removed to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of decontamination equipment, in particular to a culvert desilting system. Background technique [0002] With the improvement of people's demand for the ecological environment, there is a large demand for the dredging of urban underground ducts. At present, the most widely used method is to rely on manual dredging. The skylight or hole is opened at a suitable position in the duct, and the staff enters the duct and uses portable non-electric working tools to perform manual dredging. There are many aspects to the manual dredging method. lack of. [0003] 1. Manual dredging relies on manual work. The air in the underground duct is humid and there is water at the bottom. Considering the safety of electricity, the working tools are limited by the working conditions and are all simple and portable. Therefore, this method only relies on manual dredging Very inefficient.

AI Technical Summary

Problems solved by technology

[0003] 1. Manual dredging relies on manual work. The air in the underground duct is humid and there is water at the bottom. Considering the safety of electricity, the working tools are limited by the working conditions and are all simple and portable. Therefore, this method only relies on manual dredging very inefficient

[0004] 2. Underground ducts are densely distributed under the city, and there are a large number of them. During manual dredging operations, the opening of skylights or the spacing of openings in underground ducts is often limited, so that there are a large number of dredging points on the ground above the ducts. Manual dredging is used. The method will definitely consume a lot of manpower and material resources, and the long-term dredging operation will also seriously affect the appearance of the city and hinder people's traffic.

[0005] 3. Since the underground ducts are buried underground, various city discharges have accumulated in the ducts for a long time, and the operating environment is extremely harsh; most ducts are long-distance closed space structures, and a large amount of toxic and harmful gases are easy to accumulate in the ducts. In the process of silting, the health and safety of the staff have been greatly threatened

[0006] 4. Since the dredging of underground ducts is done by opening skylights or opening holes, the light in the ducts is seriously insufficient, and the operators only rely on portable flashlights for lighting. The dredging operation has poor sightlines, and the dredging effect on the ducts will be very large. big impact

[0007] 5. Sudden water accidents have major safety hazards

[0011] The existing technology represented by the above-mentioned patents cannot realize the cleaning of accumulations in the underground culverts with few or no people. The operating conditions in the tunnel affect the dredging quality and dredging efficiency
