Detailed Implementation
[0023] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:
[0024] A spiral-wound composite pipe covered with carbon fiber cloth includes a pipe body made of spirally wound PVC profile. Its innovation lies in the inclusion of carbon fiber cloth 5, which covers the spirally wound interface of the PVC profile. It also includes a fixing clip 4, which is pressed onto the upper end of the carbon fiber cloth and secured to the PVC profile. In this embodiment, the fixing clip is a structure formed by bending stainless steel strip.
[0025] In this embodiment, the PVC profile is composed of a profile body 3, a locking groove 1, a locking head 6, and reinforcing ribs 2. A locking groove is formed at one end of the profile body in the width direction, and a locking head is formed at the other end of the profile body in the width direction. Reinforcing ribs are provided at intervals in the middle of the profile body. The pipe body is formed by locking the upper-level locking groove and the lower-level locking head together and wrapping it around one circle at a time.
[0026] The carbon fiber cloth is impregnated with resin before use, and then bonded to the PVC profile using the carbon fiber impregnation resin. The carbon fiber cloth has horizontal sections 7 at both ends in the width direction, and an upward-protruding section 8 in the middle of the two horizontal sections. The protruding section covers the outside of the lock slot. The two horizontal sections are located on the profile body at one end of the lock head and the other end of the lock slot, respectively.
[0027] The fixed card is bent from a first inclined part 11, a first horizontal part 12, a second inclined part 13, a second horizontal part 10, a third inclined part 9, a third horizontal part 14 and a fourth inclined part 15, and the first inclined part and the second inclined part are symmetrically bent at the lower ends of the first horizontal part, the second horizontal part and the third horizontal part are horizontally bent outside the roots of the first inclined part and the second inclined part, and the third inclined part and the fourth inclined part are symmetrically bent above the roots of the second horizontal part and the third horizontal part; the first horizontal part, the second inclined part and the third inclined part jointly form a protective shell, the protective shell is buckled on the convex part of the carbon fiber cloth, the second horizontal part and the third horizontal part are respectively crimped on the profile body at one end of the lock opening clamp head and the profile body at one end of the lock opening clamping groove, and the third inclined part and the fourth inclined part are supported on the reinforcing rib.
[0028] The PVC profile, the carbon fiber cloth and the fixed card are made into a composite pipeline in a spiral winding mode. The PVC profile serves as a basic structure and provides certain shape and basic chemical stability. The carbon fiber cloth is spirally wound on the PVC profile, and the high-strength property of the carbon fiber cloth is used to enhance the overall strength of the pipeline, and the light weight of the carbon fiber cloth does not add too much burden to the pipeline. The fixed card further enhances the compression resistance and tensile resistance of the pipeline, and ensures the structural stability of the pipeline under the change of water supply pressure and complex underground environment. The spiral winding mode can tightly combine the three materials and fully exert the respective advantages, and form a composite pipeline with excellent performance.
