Description

pipe cleaner

technical field

The invention belongs to the technical field of pipeline cleaning, and in particular relates to a pipeline cleaning device.

Background technique

The transportation of petroleum is usually completed by erecting pipelines that stretch for hundreds or even thousands of kilometers. Since the temperature of petroleum is lower, the wax is easier to deposit, so it is necessary to remove the wax inside the pipeline. The pig is a special tool used to clean the pipeline driven by gas, liquid or pipeline transport medium (petroleum, liquid natural gas). They can remove crude oil, debris inside pipelines in operation, such as metal shavings, floating rust, accumulated water, gas, oil condensation, wax deposition, scaling, methane hydrate, carbide dust, etc. deposits, as well as carbon disulfide, hydrogen Sulfuric acid and other corrosive substances can reduce corrosion damage to the inner wall of the pipeline; it can also re-determine the direction of the pipeline; detect the deformation of the pipeline; check the integrity of the valves along the line; reduce the working back pressure and so on.

At present, the forward power of the pipe pig is completely dependent on the fluid medium, and the wax scraping and wax removal are completed under the promotion of the fluid medium. The defect of this pipe pig is: as the pipe pig advances, more and more wax shavings will form resistance and lead to difficulty in advancing; scraping the wax from the inner wall of the pipeline depends entirely on the scraper, and the wax scraping effect is poor. For hundreds of kilometers of pipelines, if the wax scraping work cannot be completed at one time, it will seriously affect the normal transportation of oil, and eventually cause losses to downstream users.

detailed description

The present invention will be further described below in conjunction with accompanying drawing. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.

As shown in FIGS. 1 to 6 , a pipeline cleaner includes: a body, a support wheel assembly 15 , a cleaning brush head 12 - 1 assembly and a rubber cup 13 . The body includes: a vibration assembly and a power assembly connected with the vibration assembly.

The vibration assembly includes: a mandrel 1 , a sliding sleeve 2 , a vibration spring 4 , a piston terminal 5 and a first housing 3 . The mandrel 1 has a first flow channel 1 - 1 extending along its axial direction, and a rubber cup 13 is mounted on the rear end of the mandrel 1 . The mandrel 1 and the sliding sleeve 2 form a sliding connection along its axial direction through splines. The sliding sleeve 2 is connected with the first housing 3 . A piston terminal 5 is installed on the front end of the mandrel 1, and a vibrating spring 4 is arranged between the piston terminal 5 and the sliding sleeve 2 to form an elastic connection. The piston terminal 5 has a second flow channel 5-1 extending along its axial direction. The first flow channel 1-1 communicates with the second flow channel 5-1.

The power assembly includes: an end cover 11 , a rotating shaft 7 , a second casing 6 , turbine blades 10 , a fixed valve 9 and a movable valve 8 . The rear end of the second housing 6 is connected to the front end of the first housing 3 , and an end cover 11 is mounted on the front end. The rotating shaft 7 is rotatably installed in the second housing 6. It has a third flow channel 7-1 extending forward from its rear end along the axis, and a fourth flow channel 7 extending backward from its front end along the axis. -2. The first through hole 7-3 communicates with the third channel 7-1 through its side wall, and the second through hole 7-4 communicates with the fourth channel 7-2 through its side wall. The front end of the rotating shaft 7 protrudes forward through the end cover 11 , and the cleaning brush head 12 - 1 assembly is installed on the front end of the rotating shaft 7 . On the shaft 7 between the first through hole 7-3 and the second through hole 7-4, the turbine blade 10 and the movable valve 8 having the first valve hole 8-1 are sequentially installed from back to front. A fixed valve 9 having a second valve hole 9 - 1 and in sliding contact with the movable valve is installed on the inner wall of the second housing 6 .

The supporting wheel assembly 15 is installed on the outer wall of the first housing 3 and/or the second housing 6 .

Put the pipeline cleaner into the pipeline 16, part of the fluid medium such as gas or liquid output by the pump acts on the rubber cup 13 to push the pipeline cleaner forward, and the other part enters the inside of the pipeline cleaner and acts on the turbine blade 10 to drive The turbine blades 10 drive the rotating shaft 7 to rotate. At the same time, the movable valve 8 rotates relative to the fixed valve 9 so that the second valve hole 9-1 is periodically communicated with the first valve hole 8-1, so that the flow area changes periodically, and finally the first housing 3 and the The sliding sleeve 2 moves axially relative to the mandrel 1. At this time, the cleaning brush assembly 12 is rotating to remove the dirt on the inner wall of the pipe, and it is also continuously moved back and forth to scrape off, which greatly improves the removal efficiency and makes it difficult to remove residual wax. Or other dirt can also be stripped off the pipeline inner wall under the continuous scraping of cleaning brush assembly 12.

As a preferred solution, a dynamic seal is provided between the sliding sleeve 2 and the mandrel 1 , and a dynamic seal is provided between the first housing 3 and the piston terminal 5 . Doing so can prevent the fluid medium from leaking, and avoid the situation that the pressure on the piston terminal 5 is reduced, resulting in weakening of the vibration and affecting the vibration effect.

As a preferred solution, the rear end of the mandrel 1 has a flange 1-2, and the rubber cup 13 is clamped on the flange 1-2 through the fixing ring 14. Can satisfy the fast installation of rubber cup 13 like this.

As a preferred solution, both the first valve hole 8-1 and the second valve hole 9-1 are round holes or arc-shaped long holes.

As a preferred solution, the support wheel assembly 15 includes: a support 15-3, a rotating arm 15-2, a roller 15-1 and a support spring 15-4. One end of the pivoting arm 15-2 is hingedly mounted on the support 15-3, and the other end is hingedly mounted with a roller 15-1. A support spring 15-4 is connected between the middle part of the rotating arm 15-2 and the support 15-3 to form an elastic support. As a more specific solution, there are several rotating arms 15-2, rollers 15-1 and support springs 15-4, and they are evenly arranged along the circumference of the support 15-3 so as to form uniform support for the inner wall of the pipeline. Doing so enables the pipe cleaner to cling to the inner wall of the pipe, forming elastic support in all directions.

As a preferred solution, the cleaning brush head 12-1 assembly includes: a brush holder and a brush head 12-1. The brush holder is installed on the front end of the rotating shaft 7, and the brush head 12-1 is evenly arranged along the circumferential direction of the brush holder. Doing so thoroughly cleans the inside of the pipe, preventing leaks or dead ends.

As a preferred solution, the rotating shaft 7 and the second housing 6 are connected in rotation through bearings, and the bearings are respectively located behind the first through hole 7-3 and in front of the second through hole 7-4.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. It should also be regarded as the protection scope of the present invention.
