DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a steel wire woven reinforced polyethylene composite pipe, including a main pipe 1 and a sub-pipe 2, the main pipe 1 and the sub-pipe 2 are the core components of the composite pipe, responsible for conveying fluid or gas, the right end of the main pipe 1 is fixedly connected with a hot melt pipe 3, the right end of the main pipe 1 is fixedly connected with a hot melt pipe 3, which is used to connect other components and provide stable structural support, and the outside of the hot melt pipe 3 is fixedly connected with a ring 4.

[0032] The outside of the hot melt tube 3 is fixedly connected with a collar 4, which plays a fixing and positioning role in the connection process. The right end of the hot melt tube 3 is fixedly connected with a telescopic tube 5, and the middle parts of the front and rear sides of the telescopic tube 5 are fixedly connected with positioning bolts 6. The positioning bolts 6 play a positioning and supporting role in the entire structure, so that the main pipe 1 and the auxiliary pipe 2 can maintain a stable relative position during the telescopic process. The right end of the telescopic tube 5 is fixedly connected with a hot melt tube 2 7. The connection between the hot melt tube 1 3 and the hot melt tube 2 7 is completed by the telescopic tube 5. The telescopic tube 5 is designed to deal with the thermal expansion and contraction problems of the main pipe 1 and the auxiliary pipe 2 caused by temperature changes.

[0033] refer to Figure 2 , Figure 3 The left side of the inner part of the hot-melt tube 2 7 is fixedly connected to the outside of the auxiliary tube 2, the outer part of the hot-melt tube 2 7 is fixedly connected with an outer ring 8, the inner part of the outer ring 8 is fixedly connected with an inner ring 9, the left end of the auxiliary tube 2 is fixedly connected with a support tube 10, the outer part of the inner ring 9 is in contact with the outer part of the connecting tube 11, and these components play a supporting and connecting role in the overall structure to ensure the stability and sealing of the pipeline. The left end of the connecting tube 11 is fixedly connected with a conical ring 12, the left side of the inner ring 9 is engaged with the right side of the conical ring 12, and a plurality of notches 13 are provided on the outside of the conical ring 12. The function of the notch 13 is to provide a certain shrinkage space during the connection process so as to better engage and fix with other components.

[0034] The front and rear ends of the right side of the collar 4 are fixedly connected with a connecting plate 14, the middle of the right end of the connecting plate 14 is rotatably connected to the middle of the outside of the positioning bolt 6, and the front and rear ends of the left side of the outer ring 8 are fixedly connected with a connecting plate 2 15, the adjacent sides of the two connecting plates 14 are rotatably connected to the distant sides of the two connecting plates 2 15, the middle of the left end of the connecting plate 2 15 is rotatably connected to the side of the outside of the positioning bolt 6 away from the telescopic tube 5, and the adjacent sides of the two connecting plates 2 15 are slidably connected to the front and rear sides of the telescopic tube 5. When the main pipe 1 and the auxiliary pipe 2 are subjected to temperature changes and expand and contract due to thermal changes, the connecting plate 14 and the connecting plate 2 15 will be preferentially pulled to rotate around the positioning bolt 6 through the collar 4 and the outer ring 8, and the synchronous hot-melt pipe 1 3 and the hot-melt pipe 2 7 will drive the positioning bolt 6 to deform, so that the cooperation of the positioning bolt 6 and the connecting plate 1 14 and the connecting plate 2 15 prevents the main pipe 1 and the auxiliary pipe 2 from changing in length due to thermal expansion and contraction, resulting in increased pipeline stress of the main pipe 1 and the auxiliary pipe 2.

[0035] refer to Figure 4 The outside of the main pipe 1 and the outside of the auxiliary pipe 2 are provided with a composite component for enhancing the tensile strength of the pipeline, and the composite component includes an outer layer 16, an interlayer 17, a reinforcement layer 18, an interlayer 2 19 and an inner layer 20. The outside of the main pipe 1 and the outside of the auxiliary pipe 2 are fixedly connected with the outer layer 16, the inside of the outer layer 16 is fixedly connected with the interlayer 17, the inside of the interlayer 17 is fixedly connected with the reinforcement layer 18, the inside of the reinforcement layer 18 is fixedly connected with the interlayer 2 19, and the inside of the interlayer 2 19 is fixedly connected with the inner layer 20. The outer layer 16 is made of polyethylene, and the inner layer 20 is made of polyethylene.

[0036] Polyethylene has excellent chemical stability and corrosion resistance. Interlayer 1 17 is made of adhesive resin material, and interlayer 2 19 is made of adhesive resin material. The adhesive resin material has excellent bonding properties and can effectively bond different layers of the pipeline together. By using the adhesive resin in the middle two layers, the overall structural strength of the composite pipe can be enhanced, and its pressure resistance and tensile resistance can be improved. The reinforcement layer 18 is made of steel wire braided material. The steel wire braided mesh material can enhance the structural strength and pressure resistance of the pipeline, so that the pipeline can withstand higher internal pressure without deformation or rupture.

[0037] Working principle: the right end of the left main pipe 1 is melted and connected with a ring 4. When it is necessary to connect another pipeline auxiliary pipe 2 for overall docking and fixing, the support pipe 10, connecting pipe 11 and conical ring 12 fixed to the auxiliary pipe 2 can be inserted into the hot-melt pipe 2 7, and the inner ring 9 inside the hot-melt pipe 2 7 can contact the outside of the notch 13 to squeeze the notch 13 to shrink, and then engage with the outer position of the connecting pipe 11 and be resisted by the notch 13. At this time, the main pipe 1 and the auxiliary pipe 2 are initially fixedly connected, which is convenient for the staff to connect the pipeline. Then the staff will melt and connect the right end of the hot-melt pipe 2 7 with the outside of the auxiliary pipe 2, so as to achieve the quick connection and fixation of the pipeline while maintaining the sealing.

[0038] In the above structure, the middle parts of the hot melt pipe 1 3 and the hot melt pipe 2 7 are fixedly connected with a telescopic pipe 5. The function of the telescopic pipe 5 is that when the main pipe 1 and the auxiliary pipe 2 expand and contract due to temperature changes, the connecting plate 1 14 and the connecting plate 2 15 will be preferentially pulled to rotate around the positioning bolt 6 through the sleeve ring 4 and the outer ring 8. The hot melt pipe 1 3 and the hot melt pipe 2 7 will drive the positioning bolt 6 to deform synchronously, so that the cooperation of the positioning bolt 6 and the connecting plate 1 14 and the connecting plate 2 15 can prevent the main pipe 1 and the auxiliary pipe 2 from changing in length after thermal expansion and contraction, resulting in increased pipe stress of the main pipe 1 and the auxiliary pipe 2, resulting in compression between the pipes and causing self-damage. When water flows through the main pipe 1 and the auxiliary pipe 2, the main pipe 1 and the auxiliary pipe 2 will vibrate themselves and transmit the vibration to the positioning bolt 6 through the hot melt pipe 2 7 and the sleeve ring 4, driving the positioning bolt 6 to rotate and expand, and the elastic potential energy of the material of the positioning bolt 6 will buffer the received vibration, thereby protecting the connection between the main pipe 1 and the auxiliary pipe 2 and preventing pipe vibration from causing wear.

[0039] The outer layer 16 and the inner layer 20 of the pipe are both made of polyethylene, which effectively enhances the corrosion resistance, chemical resistance and friction resistance reduction performance of the pipe, while the interlayer 17 and the interlayer 2 19 are made of adhesive resin. This material has excellent bonding properties and can effectively bond different layers of the pipe together. By bonding the adhesive resin to other layers, the overall structural strength of the composite pipe is effectively enhanced, and its pressure resistance and tensile resistance are improved. Combined with the steel wire braiding of the reinforcement layer 18, the tensile strength of the pipe is effectively increased.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
