Description

Multifunctional bionic pipe cleaner and cleaning method thereof

Technical Field

The invention relates to the technical field of grouting, non-excavation, drilling, oil and gas storage and transportation, lifeline engineering, underground comprehensive pipe gallery, sponge city and other engineering, in particular to a multifunctional bionic pipe cleaner and a cleaning method thereof.

Background

Grouting (also called Grouting), is widely used for reinforcing and preventing seepage of rock and soil mass in projects such as water conservancy and hydropower, traffic, buildings, mines and the like, and is also a common technical means for slope protection, sand slide slope protection, water and soil conservation and the like in geological disaster treatment and geological environment protection. The Trenchless Technology (Trenchless Technology or No-Dig) is used for detecting, laying, repairing or replacing underground pipelines under the condition of micro-excavation or Trenchless excavation, has the technical advantages that the open excavation method does not damage the surface environment, does not influence the ground traffic and the like and cannot be compared with the open excavation method, and is a novel environment-friendly underground pipeline construction Technology with great development potential. Drilling and Tunneling is to break rock-soil layers in a mechanical and chemical way and form holes or tunnels meeting the specification and quality requirements in rock-soil bodies, thereby realizing the purposes of exploration and development of mineral resources (including unconventional energy sources such as natural gas hydrate/combustible ice, shale gas, oil shale and the like), acquisition of rock (ore) cores and ice cores, disaster prevention and early warning, implementation of engineering construction and the like. Oil and Gas Storage and Transportation (Oil & Gas Storage and Transportation) is a link for connecting links of Oil and Gas production, processing, distribution, sale and the like, and mainly comprises Oil and Gas field gathering and Transportation, long-distance conveying pipelines, storage, loading and unloading, urban Transportation and distribution systems and the like. Lifeline Engineering is an Engineering system for traffic, communication, water supply, water drainage, power supply, gas supply, oil transportation and the like, which is closely related to the life of people and has great influence on social life and production. An Underground comprehensive Pipe Gallery (Underground Pipe Gallery) is a structure and accessory facilities which are built in the Underground of a city and used for accommodating two or more types of urban engineering pipelines. The Sponge City (Sponge City) is a City with good elasticity in adapting to environmental changes and natural disasters caused by rainwater, and can also be called a water elasticity City.

The above engineering fields can be successfully implemented without opening pipes, and the pipes are mainly members with through holes in the interiors of pipelines, drill rods, casings and the like. Taking the grouting operation as an example, firstly, a hole with a certain specification needs to be drilled in a stratum (rock-soil body), then a grouting pipe is put into the hole, cement or other types of grout are poured into a rock crack or a soil body hole, and in the process, a drill pipe, a casing pipe, a pipeline and the like need to be used. The drill rod is used as a junction for establishing a ground surface drilling device and an underground rock breaking tool, and plays important roles of transferring bit pressure and torque, conveying cleaning media, extracting a rock (ore) core, prolonging a drill column and the like; in addition, when the drilling is difficult to be effective when the drilling is in a complex stratum and is close to a mud retaining wall for plugging, casing pipes are usually needed to ensure the smooth implementation of drilling (well) operation, so the use and daily maintenance conditions of a drill rod and the casing pipes directly determine the use working conditions and the service lives of the drill rod and the casing pipes; various pipelines laid on the ground or buried underground are essential as media for conveying fluids or fluid-solid coupling media such as water, slurry, cement slurry, ore slurry, petroleum, natural gas, shale oil/gas, coal bed gas and the like, especially for long-distance conveying. However, after the pipe is used for a period of time, the inner wall of the pipe has problems of sludge, scaling, corrosion and the like which affect the normal operation of the pipeline system, and the like which are difficult to avoid.

In summary, in order to improve the adverse effect of dirt such as slurry, cement slurry, oxidation corrosion layer, corrosion layer and the like adhered to the inner wall of the pipe on the service condition and service life of the pipe, and ensure the smooth implementation of various engineering technical fields such as grouting, non-excavation, drilling, oil and gas storage and transportation, lifeline engineering, underground comprehensive pipe gallery, sponge city and the like, the inner wall of the pipe needs to be cleaned as required.

The existing pipe cleaning device can not thoroughly clean the inner wall of the pipe, the cleaning method is single, the energy consumption is high during cleaning, the operation efficiency is low, and the flexibility, the adaptability and the stability are not strong.

8. The multifunctional biomimetic pig according to claim 1, characterized in that: the plugging end cover (9) comprises a plugging end cover connecting section (93) and a cylindrical plugging column (92), a plugging end cover central groove is axially formed in the left side of the plugging end cover connecting section (93), and the plugging column (92) is axially arranged in the plugging end cover central groove;

the diameter of the plugging column (92) is matched with that of the liquid flow channel (12), and the right end of the central shaft (1) is in sealing connection with the plugging end cover (9).

9. The multifunctional biomimetic pig according to any of claims 1 to 8, characterized in that: the liquid flow channel (12) and the internal wall face of air current passageway (14) and the internal wall face of nozzle (8) all separates and is equipped with a plurality of annular grooves (84), annular groove (84) set up perpendicularly corresponding the liquid flow channel (12) and the internal wall face of air current passageway (14) and on the internal wall face of nozzle (8).

10. A method for cleaning the multifunctional bionic pipe pig as claimed in claim 9, characterized by comprising the following steps:

step 1: the liquid inlet connecting port (11) and the gas inlet connecting port (13) are respectively communicated with an external high-pressure liquid flow pipe communicated with cleaning liquid and an external high-pressure gas flow pipe communicated with compressed gas;

step 2: the multifunctional bionic pipe cleaner is placed into the pipe tool (0) to be cleaned from one end, and one end provided with the plugging end cover (9) faces the other end of the pipe tool (0) to be cleaned;

and step 3: the method comprises the following steps of communicating an external high-pressure liquid flow pipe and an external high-pressure airflow pipe, and cleaning the inner wall of a pipe to be cleaned (0), specifically: cleaning liquid enters the liquid flow channel (12) from the liquid inlet connecting port (11) and then is sprayed out from the nozzle (8) positioned at the right end of the central shaft (1) to form a plurality of bundles of high-pressure liquid flows and clean the whole section of the inner wall surface of the pipe (0) to be cleaned;

compressed gas enters the gas flow channel (14) from the gas inlet connecting port (13) and is sprayed out from the corresponding nozzle (8) to the left, the formed high-pressure gas flow cleans and dries the inner wall of the pipe, the generated reverse thrust drives the whole pipe cleaner to move rightwards in the pipe (0) to be cleaned, synchronously, the rubber ring (2) scrapes and cleans the inner wall of the pipe cleaner, and the annular magnet (6) attracts metal debris in the pipe and brings the metal debris out of the pipe (0) to be cleaned;

and 4, step 4: repeating the step 2 and the step 3, and cleaning the inner wall surface of the pipe (0) to be cleaned for a plurality of times.
