Description
Technical field
The invention belongs to pipe technology fields, and in particular to a kind of dredging device for water conservancy projects.
Background technique
Urban discharging pipeline has more long construction history in China, there is special pipe duct very early, for excluding city
Sewage and rainwater, each dynasty capital also all built many drainage systems, these systems construction is more complete.In urban duct reality
There is also some not perfect places, such as pipeline product silt problem in the use process of border.
The siltation problem of drainage pipeline is due to caused by the deposition of solids of silt and suspension in pipe-line system mostly
, this phenomenon does not occur only in drain header, can also betide in branch drain line.Sewage is in drainage pipeline
Since the drag losses of pipeline reduce flow velocity, the silt and solid suspension carried in sewage is likely to sink wherein for movement
It accumulates, so that drainage pipeline product be caused to become silted up.In addition, interflow tubing giving sufficient strength is in the flow and pipeline that rainy season and dry season receive sewage
The difference of effluent flow rate is very big, this will lead to the larger particles that rainy season originally can be pulled away or bulky grain suspended matter because dry season manages
The reduction of flow and flow rate in road and deposit, can also cause drainage pipeline to deposit, at the same partial particulate object have it is certain viscous
Attached property further increases pipe dredging difficulty in inner wall of the pipe bonding, such as dredging not in time after pipeline product is become silted up, may make
At line clogging, this is unfavorable for urban duct blowdown, also provides compared with multi-method or equipment solve pipeline product silt in the prior art
Problem, for example, by using chemical reagent, but chemical reagent often will cause pollution to water body, for another example use pipe dredging machine
People, but this kind of high equipment cost, complicated for operation, unsuitable realization is a wide range of to promote the use of.

Water body is inputted after connection supervisor by spray module to spraying water body in tube wall by water pump under negative pressure state after operation 4 times,
And cancelling the first blocking component and the second blocking component by computer-controlled electromagnetic iron group divides inner wall of the pipe the sealing of pipeline
From fixed line mud and dredging generate slime water be quickly discharged from pipeline by spray module injection water, complete dredging
Work, then make by motor-driven gear rack gear mobile device is in pipeline when not carrying out closure dredging to pipeline to realize
Movement, expand pipe dredging range.
Peripheral control unit described herein is computer, power on/off and monitoring pressure for computer-controlled electromagnetic iron group
Force snesor and air pressure sensing belong to existing well-known technique, and those skilled in the art have the ability to realize and understand, not excessive herein
It repeats.First rubber ring and the second rubber ring of the invention is isoprene rubber, the material of the first sealing plate and the second sealing plate be non-ferric,
The substances such as cobalt, nickel.
First rubber ring of the first blocking component and the deformation principle of the second rubber ring of the second blocking component are identical, and first
The pressure that blocking component and the second blocking component solve existing seal assembly and when seal for pipe joints generates is excessive to lead to pipeline
Damaged or device breakage problem.
Sparge pipe injection water flow velocity includes but is not limited to 120 ~ 150m/s, can also be 120 m/s or 121 m/s or
122 m/s or 123 m/s or 124 m/s ... or 149 m/s or 150 m/s.
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore equivalent changes made in accordance with the claims of the present invention, is still within the scope of the present invention.
