Self-control municipal drainage pipeline network dredger and control method thereof

Abstract

The invention discloses a self-control municipal drainage pipeline network dredger and a control method thereof. The dredger comprises a wall, a retaining door, a hydraulic rod, a hydraulic system, aliquid level meter and a control unit. The control method includes: S1, being in an idle state; S2, being in a retaining state; S3, retaining; S4, returning to the idle state. The dredger is simple inmounting, high in suitability, flexibly adjustable in pipeline flushing frequency and strength, stable in running, low in energy consumption and capable of perfectly replacing manual dredging.

Description

technical field [0001] The invention relates to the technical field of dredgers, in particular to a self-controlled dredger for municipal drainage pipe networks and a control method thereof. Background technique [0002] The municipal drainage network mainly refers to the rainwater and sewage pipes under the municipal roads, commonly known as "sewer pipes". The drainage pipe network is divided into rainwater pipes, sewage pipes and confluence pipes according to the collection methods of rainwater and sewage. The municipal pipe network is an important infrastructure and the lifeblood of a city. It is the material basis for ensuring the development of people's lives and social production, and it is also the central issue of urban development and construction and one of the restrictive factors for economic development. [0003] Today's municipal drainage network generally has the problem of pipeline silting, the main reasons are: the sewage flow is small in dry season, the fl...

AI Technical Summary

Problems solved by technology

[0003] Today's municipal drainage network generally has the problem of pipeline silting, the main reasons are: the sewage flow is small in dry season, the flow velocity is low, and a large amount of suspended solids are easy to deposit in the pipeline; due to the limitation of external conditions, the slope of the pipeline design is small; The existence of siphon pipes, 90-degree bends, sharp bends, etc. lead to silting of pipes, and the accumulation and blockage of silt in the municipal pipe network will cause sewage overflow and water accumulation on the road, which not only pollutes the environment, but also hinders traffic and brings great harm to residents’ lives. A lot of inconvenience has come, so how to effectively clean up the pipeline silt, prevent the municipal pipe network from clogging, prevent sewage overflow, and ensure the normal operation of the municipal pipe network system is an important problem to be solved urgently
