Technical field

The application relates to the field of pipeline sealing, in particular to a magnetically guided two-component adhesive pipeline leakage sealing device.

Background technique

AB glue is another name for two-component mixed hardening glue, AB glue is called two-component adhesive. Only after AB glue is mixed can its bonding performance be realized. AB glue can be used for strong bonding of metal, plastic, ceramics, glass, wood, stone, hardware, ABS, magnet, acrylic, stainless steel and iron.

Pipeline damage can be roughly divided into three categories: The first category is local small damage, such as small holes or small cracks. This type of leakage is usually caused by localized corrosion or welding defects. The second type is partial damage, which requires a protective cover on the outside of the steel pipe or replacement of the damaged part with a short pipe. This type of damage is most common, such as the hooking of a ship's anchor. The third type is large-scale damage on a relatively long pipe section, which greatly reduces the axial strength of the pipe. In this case, the damaged part needs to be replaced with a long pipe section.

Local leakage of pipelines due to local corrosion or welding defects is the most common failure mode. For such failure modes, the following solutions are proposed in the prior art:

For example, Chinese patent CN108458202A discloses a natural gas pipeline leakage plugging device, which includes a clamping frame and two sets of plugging mechanisms symmetrically arranged on the clamping frame. The plugging mechanism includes an adjusting screw, a positioning rod, a plugging plate, and a gauze. And a rubber tube equipped with sealant, the gauze net is arranged on the gasket, the gauze is located between the gasket and the pipe, the gasket is provided with a through hole communicating with the gauze, the rubber hose is arranged on the pressure plate, and the glue outlet of the hose When plugging the leak, the sealant in the hose enters the gauze through the through hole, and the infiltrated gauze blocks the leakage point; this application can improve the sealing performance and prevent a small amount of leakage; extend the leakage after plugging The service life of the pipeline saves costs.

For example, the Chinese patent number "200720097226.3" disclosed a pipeline U-shaped plugging card on July 30, 2008. The technical solution is that the pipeline U-shaped plugging card is buckled into a circular connection by an arc-shaped steel plate and a U-shaped connecting arm. The arc-shaped steel plate is provided with connecting ears at both ends, the connecting ears are provided with bolt through holes, the arc-shaped steel plate is embedded with a rubber plate for plugging, and the U-shaped connecting arm is provided with threads at both ends. However, in actual use, professional tools are needed to fix the plugging card on the pipeline, which has the disadvantages of long plugging time and inconvenient plugging.

For example, the Chinese patent number "201410598602.1" disclosed a self-protected leak-proofing device under pressure on February 18, 2015. The technical solution is that the leak-proofing device under pressure includes a clamp, a plugging plate and a chain. The clamp A chain is used to clamp the plugging plate on the pipeline, the clamp uses a screw structure to tighten the chain, and the plugging plate uses a ball lock structure to reduce the pressure on the plugging plate at the pipeline leakage. However, the patent still has the following shortcomings: First, the structure of the plugging device is complicated, and the cost is high; second, the fixing process of the plugging device is complicated, which is not conducive to fast plugging; third, because the pipeline is of a circular structure, the leaked location Pressure, pipeline vibration and weather changes make it difficult for the chain to effectively fix the plugging plate, which affects the plugging effect of the plugging plate.

The Chinese patent number "CN201520182822.6" discloses a pipeline plugging device, which includes a clamping frame and two sets of plugging mechanisms symmetrically arranged on the clamping frame. The plugging mechanism includes an adjusting screw, a positioning rod and a plugging plate , The adjusting screw is threadedly connected to the clamping frame, one end of the positioning rod is movably clamped in the plugging plate, and the other end is screwed to the adjusting screw. When leaking, two sets of plugging mechanisms are symmetrically fixed on the clamping frame On the pipeline, the adjusting screw and the plugging plate cooperate to block the leakage point. This application can immediately block the leakage point without stopping the transportation when a pipeline leak is discovered. However, when the above-mentioned technology plugging plate is used to block the leakage point, because the outer wall of the pipeline is exposed to the external harsh environment for a long time, the outer wall is rusted, and the leakage point is not tightly sealed by the plugging plate, which will also cause a small amount of leakage.

In addition to the inherent problems of the above-mentioned patents, there is also a common shortcoming, that is, it cannot realize double-sided leakage compensation for the inner and outer sides of the pipeline. Therefore, the extension of the pipeline service time described in it has certain limitations, and it can only be realized for both the inner and outer sides of the pipeline. Repairing leaks can better extend the service life of the pipeline.

Summary of the invention

In order to overcome the above-mentioned technical defects, the present application provides a device that can seal the inside and outside of the pipeline at the same time, which fundamentally extends the service life of the pipeline.

The specific composition and principle of the program are:

A magnetically guided two-component adhesive pipeline leakage sealing device, including a guiding permanent magnet, a suction tube, an outer film, an inner film, a frame, a built-in permanent magnet, a capsule, a broken cone, a coil I, a coil II, and a battery Group, wiring module, control module, flange plate, fastening bolt, gasket, magnetic fluid solution, built-in permanent magnet, capsule body, A glue, B glue, adsorption permanent magnet, magnetic isolation material, driving wheel.

This application uses the primary and secondary buoyancy principles of the magnetic fluid, that is, as shown in Figure 1, before all the coils are powered on to generate a magnetic field, because the two capsules contain permanent magnets, they will automatically float in the magnetic fluid solution. When the lower coil II is powered on, the two capsules will fall and collide with the broken cone at the bottom of the frame and be punctured. The glue A and glue B inside the punctured capsule will flow out. Due to the exclusiveness of the magnetic fluid, the glue AB will automatically flow to the inner film on the upper right side of the frame and be mixed at the inner film. The alternating on and off of the coil I and the coil II can realize the movement of the entire capsule in the magnetic fluid, so that all the glue inside it flows out.

When the AB glue is mixed, the suction pipe is used to suck from the outer wall of the pipe, so that the mixed glue is sucked to the outside of the pipe through the leak hole. After the suction is completed, a small movement of the guide permanent magnet can make the contact surface between the inner film and the inside of the pipe fully filled with colloid. The inner and outer sides of the pipeline are fixed for a period of time to complete the leakage of the inner and outer pipes.

Preferably, the inner film is installed on the upper side of the frame, and the running wheel is in a height direction.

Preferably, the capsule body is equipped with a permanent magnet and B glue, and the capsule body is equipped with a permanent magnet and A glue.

Preferably, the magnetic isolation material is placed under the adsorption permanent magnet.

Preferably, the whole set utilizes the principle of permanent magnet adsorption, the paramagnetism of the magnetic fluid, the fluidity of the magnetic fluid, the principle of first-order buoyancy of the magnetic fluid, and the principle of the second-order buoyancy of the magnetic fluid.

The beneficial effects of this application are: this application can solve the internal and external leakage compensation of pipeline leakage, and cleverly utilizes the characteristics of AB glue, magnetic fluid and permanent magnets, completes the leakage compensation on both sides of the pipeline, and realizes double insurance for the pipeline leakage. Basically extend the service life of the pipeline.

detailed description

The application will be further explained below in conjunction with the drawings:

The structure diagram of the magnetically guided two-component adhesive pipe leakage sealing device shown in Figure 1, as shown in the figure, the device includes: a guiding permanent magnet 1, a suction tube 2, an outer film 3, an inner film 4, and a frame 5. Built-in permanent magnet 6, capsule body 7, crushing cone 8, coil I9, coil II10, battery pack 11, wiring module 12, control module 13, flange plate 14, fastening bolt 14-1, gasket 14 -2. Magnetic fluid solution 15, built-in permanent magnet 16, capsule body 17, A glue 18, B glue 19, adsorption permanent magnet 20, magnetic isolation material 21, running wheel 22.

The specific implementation steps are as follows:

Open the fasteners on the flange plate 14 and put the capsule body 7 in, and then install the gasket 14-2 and the flange plate 14. From the upper right side of the frame 5, the magnetic fluid solution 15 is filled. Place the device on the inner wall of the pipeline, because there are debris on the inner wall of the pipeline that will affect the adsorption and walking effect, so it is necessary to ensure that the inner wall of the pipeline is smooth and free of debris. After confirming that the adsorption is complete, place the guide permanent magnet 1 on the outside of the pipe. Preferably, the guide permanent magnet 1 is made of neodymium iron boron strong magnetic material, which can enhance the adsorption force of the pipe and the frame 5. The guide permanent magnet 1 guides the device to move, and determines the position of the leakage opening and the film in the frame according to the approximate size of the frame. Place the outer film 3 at the leakage port outside the pipe. At this time, the lower coil II is powered on, so that the two capsules fall and collide with the broken cone at the bottom of the frame and are punctured. The A and B glue inside the punctured capsule will flow out. Due to the exclusivity of the magnetic fluid, the AB glue will It automatically flows to the inner film on the upper right side of the frame and realizes mixing at the inner film. The alternating on and off of the coil I and the coil II generates a low-frequency alternating magnetic field, which can realize the movement of the entire capsule in the magnetic fluid, so that all the glue inside it flows out. The alternating magnetic field will promote the flow of the magnetic fluid solution in the frame, and the liquid flow will promote the AB glue to achieve the solution mixing.

When the AB glue is mixed, the suction pipe is used to suck from the outer wall of the pipe, so that the mixed glue is sucked to the outside of the pipe through the leak hole. After the suction is completed, a small movement of the guide permanent magnet can make the contact surface between the inner film and the inside of the pipe fully filled with colloid. The inner and outer sides of the pipeline are fixed for a period of time to complete the leakage of the inner and outer pipes.

The above-mentioned specific implementations are used to explain the method and core idea of the application, but not to limit the application. For those skilled in the technical field, without departing from the principles of this application, any modifications and changes made to this application fall within the protection scope of this application.
