Referring to fig. 3-7, fig. 3 is a cross-sectional view of a pipe 10 according to some embodiments of the present application; FIG. 4 is a schematic illustration of a pipe 10 according to some embodiments of the present application without a liquid filler 15; FIG. 5 is a schematic illustration of solidification of liquid filler 15 to effect occlusion in accordance with some embodiments of the present application; FIG. 6 is a diagram illustrating an example configuration of a pipe 10 according to some embodiments of the present application; FIG. 7 is a diagram illustrating an example of the structure of a pipe 10 according to other embodiments of the present application; fig. 8 is a cross-sectional view of a pipe 10 according to further embodiments of the present application.

Referring to fig. 3-7, an embodiment of the present application provides a pipe 10, the pipe 10 including a first pipe body 11, a shield 12, and a liquid filler 15. The shielding member 12 covers at least a portion of the outer peripheral surface of the first tube body 11, and the shielding member 12 and the outer peripheral surface of the first tube body 11 define a housing chamber 14 together. The liquid filler 15 fills the accommodating chamber 14, and the liquid filler 15 is configured to solidify upon contact with air.

The first pipe 11 may be used for transporting or discharging gas, liquid, fluid with solid particles, or the like.

The guard 12 is a guard and protection measure made on the outer peripheral surface of the first pipe body 11 for reducing the possibility of damage to the first pipe body 11. If the pipe 10 is impacted externally, it is in a position protected and protected by the guard 12. The protector 12 is first impacted and the protector 12 buffers the first pipe 11 against the impact force, thereby reducing the possibility of damage to the first pipe 11.

The guard 12 may be provided only at a position where the first pipe body 11 is easily damaged, so as to save material. Of course, the protecting piece 12 may also be directly sleeved on the outer peripheral surface of the first tube body 11, so as to improve the protection and protection effect.

As shown in fig. 4, the shielding member 12 and the outer circumferential surface of the first tube body 11 define a receiving cavity 14, the receiving cavity 14 is a cavity structure formed between the outer circumferential surface of the first tube body 11 and the inner circumferential surface of the shielding member 12, and the receiving cavity 14 is used for filling the liquid filler 15.

The liquid filler 15 is a substance that can solidify when exposed to air. When the protective piece 12 is firstly impacted and damaged, the liquid filler 15 is in contact with air at the damaged position to solidify, so that the damaged position is plugged, and the pipeline 10 is repaired. As shown in fig. 5, the liquid flows under its own action to seal the broken position of the guard 12, and the solidification position a exceeds the guard 12. Of course, in other embodiments, the coagulation site may also be lower than the outer peripheral surface of the guard 12. The liquid filler 15 can relieve stress concentration at the damaged position of the protecting piece 12 after solidification, reduce the possibility that the protecting piece 12 is further damaged to influence the protecting effect on the first pipe body 11, and simultaneously reduce the possibility that external pollutants enter the pipeline 10 from the damaged position to cause the damage to the first pipe body 11.

The environment of the liquid filling 15 in the accommodating cavity 14 should be in a closed state, which belongs to a closed environment, and the protecting piece 12 and the first pipe body 11 should be in sealing connection, so that the protecting piece 12 and the outer peripheral surface of the first pipe body 11 jointly define the closed accommodating cavity 14, and the liquid filling 15 is ensured not to be contacted with air and react with the air. The connection position between the protecting member 12 and the first pipe body 11 may be reserved with a part of the connection position not connected, and the connection position is used as a filling inlet of the liquid filler 15, and the connection position is connected after filling is completed, for example, in the pipe 10 shown in fig. 6, the end face of the pipe 10 is not closed, the connection position is used as a filling inlet of the liquid filler 15, and the end face of the pipe 10 is closed after filling is completed. Of course, a filling inlet is also provided in the shielding member 12, and the filling inlet is closed after filling is completed.

The liquid filling 15 is in a relatively stable state within the closed receiving chamber 14. The liquid filler 15 may be configured to solidify after reacting with the gas component in the air, or the liquid filler 15 may be configured to solidify after reacting with the water vapor in the air, or the liquid filler 15 may be configured such that a part of the component in the liquid is a highly volatile substance and then is quickly volatilized after remaining in the air, resulting in solidification of the remaining component.

As shown in fig. 3 to 6, the protecting member 12 may be sleeved on the outer peripheral surface of the first pipe body 11, and the protecting member 12 covers the outer peripheral surface of the first pipe body 11, where the accommodating cavity 14 has a ring-shaped structure. Of course, in other embodiments, the protecting member 12 may be a half-pipe structure, and the protecting member 12 covers half of the outer peripheral surface of the first pipe body 11, and the accommodating cavity 14 is half of the ring structure. Alternatively, in the extending direction X of the duct 10, the dimensions of the shielding member 12 are smaller than those of the first tubular body 11. As shown in fig. 7 and 8, the protector 12 covers only a part of the outer peripheral surface of the first pipe body 11, and the size of the protector 12 is smaller than the size of the first pipe body 11 in the extending direction X of the pipe 10.

Fig. 3-7 only show implementations in which the cross-section of the duct 10 is circular, it being understood that in other implementations the cross-section of the duct 10 may also be rectangular, elliptical, profiled, etc.

In this embodiment, the protecting member 12 and the outer peripheral surface of the first tube 11 define a containing cavity 14, and the liquid filler 15 is filled in the containing cavity 14. The protection piece 12 plays a protective role on the first pipe body 11, and simultaneously, after the protection piece 12 is damaged, the position where the liquid filler 15 contacts with air can be solidified to block the damaged position, so that the protection piece 12 is repaired, the self-repairing function is managed, the use reliability of the pipeline 10 is improved, and the service life of the pipeline 10 is prolonged. This is faster than the manual investigation repair pipeline 10 of operating personnel, and repair efficiency is high, is favorable to reducing pipeline 10 and in time the secondary risk that leads to because of repairing.

In some embodiments, the liquid filler 15 is a foam or 502 glue.

The foaming glue is polyurethane elastic sealing foaming filling material which is solidified by moisture. The foaming glue has the advantages of environmental protection, energy saving, convenient use and the like, and can be suitable for sealing, plugging and filling gaps. The special polyurethane product formed by filling components such as polyurethane prepolymer, foaming agent, catalyst and the like can be used as a liquid filler 15 to be filled in the accommodating cavity 14. The protection member 12 and the first pipe body 11 may be made of a pressure-resistant material. When the protective piece 12 is damaged, polyurethane prepolymer in the foaming glue can expand rapidly and react with air or moisture in a contacted matrix in a solidification way to form foam, the foam is plugged at the damaged position, the pipeline 10 is repaired, and the repair efficiency of the pipeline 10 is improved to a certain extent.

The 502 glue is a single-component product synthesized by using alpha-ethyl cyanoacrylate as a main material and adding tackifier, stabilizer, toughening agent, polymerization inhibitor and the like, and the 502 glue is catalyzed to quickly polymerize, solidify and adhere when exposed to air and contacts with trace water vapor in the air, and is called as an instant adhesive. And the 502 glue is used as the liquid filler 15 to be filled in the accommodating cavity 14, when the protective piece 12 is damaged, the 502 glue is quickly solidified to block the damaged position, so that the pipeline 10 is repaired, and the repairing efficiency of the pipeline 10 is improved to a certain extent.

The liquid filler 15 may be filled by avoiding the conditions required for solidification of the liquid filler 15, for example, the glue 520 is substantially solidified by reacting with water vapor in the air, and the receiving cavity 14 is filled with the glue 502 in the drying low-temperature release, and the filling position is sealed and sealed quickly after filling.

Of course, in other embodiments, the liquid filler 15 may also be 401 glue, 415 glue, or the like.

In some embodiments, the guard 12 may also be a tubular structure, and for convenience of description, the guard 12 is defined as the second tube 13 in this embodiment. Referring to fig. 3 to 6, the protection member 12 is a second pipe body 13, and the second pipe body 13 is sleeved on the first pipe body 11.

The second pipe body 13 is sleeved on the first pipe body 11, the inner peripheral surface of the second pipe body 13 and the outer peripheral surface of the first pipe body 11 jointly define a containing cavity 14, and the containing cavity 14 is filled with liquid filler 15. In the pipeline 10 with the structure, the second pipe body 13 is sleeved on the first pipe body 11, and the second pipe body 13 covers the first pipe body 11 in the axial direction of the first pipe body 11, so that the protection and protection effects are better.

It should be understood that fig. 3 to 6 are embodiments corresponding to fig. 7, 8.

Referring to fig. 4, in some embodiments, the pipe 10 further includes a support 16, the support 16 being supported between the outer circumferential surface of the first pipe body 11 and the inner circumferential surface of the second pipe body 13.

The support 16 supports the first pipe body 11 and the second pipe body 13 and also serves to connect the first pipe body 11 with the second pipe body 13.

The support 16 may be one or more.

The support 16 may be the same material as the first tube 11 and the second tube 13.

The support piece 16 is used for supporting between the first pipe body 11 and the second pipe body 13, and the first pipe body 11 and the second pipe body 13 are mutually restrained through the support piece 16, so that the shapes of the second pipe body 13 and the first pipe body 11 are stabilized, the structural strength of the pipeline 10 is improved, the use reliability of the pipeline 10 is improved, and the service life of the pipeline 10 is prolonged.

Referring to fig. 4 and 5, in some embodiments, the support 16 divides the receiving chamber 14 into a plurality of chambers that are independent of one another.

In other words, the support 16 divides the housing chamber 14 into a plurality of chambers independent of each other, the respective chambers not communicating with each other.

The number of support members 16 may be one, with one support member 16 being able to divide the containing cavity 14 into two separate chambers. Of course, the number of the supporting members 16 may be plural, and the plurality of supporting members 16 may divide the accommodating chamber 14 into a plurality of chambers independent of each other.

The supporting member 16 divides the accommodating chamber 14 into a plurality of chambers independent of each other, so that the liquid filler 15 can be filled in each chamber, and when the liquid filler 15 in one of the chambers performs the plugging repair of the damaged position of the pipeline 10, the liquid filler 15 in the other chamber can be unaffected. And meanwhile, the use amount of the liquid filler 15 solidified during the plugging and repairing of the pipeline 10 is reduced, so that the cost is favorably controlled.
