Example 1
As shown in fig. 1 to fig. 3, in this embodiment, a modified polyolefin MPO steel-plastic composite reinforced winding drain pipe is specifically provided, and aims to improve the performance of the winding pipe in multiple aspects of ring stiffness, tensile resistance, corrosion resistance, wear resistance and the like by optimizing the winding drain pipe.
As is well known, in the prior art, the winding drain pipe is formed by spirally winding and processing a plate, the plate forms a spiral lap joint along with the winding process, the joint strength of the lap joint is an important factor influencing the tensile strength of the winding pipe, and in the prior art, the lap joint is mostly directly bonded by using an adhesive.
In this embodiment, the plate includes an outer pipe layer and an inner pipe layer respectively located on the outer surface and the inner surface of the wound drain pipe, the inner pipe layer and the outer pipe layer are integrally formed by double-layer compounding to form a composite reinforced wound drain pipe, and the outer pipe layer and the inner pipe layer are respectively double-layer compounded by adopting different materials and colors, so that the product has an obvious identification degree on appearance to form a double-color double-layer wound drain pipe; in practical application, in order to further improve the corrosion resistance and the wear resistance of the winding pipe in the use process, the inner pipe layer is made of a wear-resistant and corrosion-resistant material, the wear-resistant and corrosion-resistant material is generally made of ultra-high molecular weight polyethylene, and the inner pipe layer made of the wear-resistant and corrosion-resistant material can improve the wear resistance and the corrosion resistance of the drain pipe to flowing fluid so as to prolong the service life of the pipe body.
One side of outer pipe layer is equipped with the male head of overlap joint, and the opposite side is equipped with the female head of overlap joint with the male head looks adaptation of overlap joint, and along with panel at the winding in-process, the male head of overlap joint of panel one side and the female head mutual adaptation of overlap joint of spiral winding back panel opposite side to the winding shaping that realizes panel is the winding pipe. In practical application, in order to overcome the defect that the tensile strength of the existing winding pipe at the lap joint of the plate is not enough, the lap joint surface between the lap joint male head and the lap joint female head adopts the zigzag snap fit, so that the friction force and the tensile strength at the lap joint are further improved. When carrying out the product design, to the intensity promotion of overlap joint, can further lengthen the overlap joint regional length between public head of overlap joint and the overlap joint female head, under the holding of interpolation of cockscomb structure interlock, can ensure behind shaping winding pipe, it can realize that the winding pipe has stronger tensile strength, and under the practical application scene, the difficult condition that appears becoming flexible, drops in winding overlap joint of winding pipe takes place.
In order to further improve the ring rigidity of the winding pipe, four reinforcing ribs are arranged on the surface area between the lap joint male head and the lap joint female head, and each reinforcing rib is arranged along the longitudinal central line direction of the outer pipe layer. When the plate is spirally wound, the reinforcing ribs can also improve the integral ring rigidity of the wound pipe. When in actual application, each the inside of strengthening rib all is embedded into has strengthened the steel band, strengthens the steel band and arranges along the trend of strengthening rib, strengthens the effect of steel band and can further promote the intensity of strengthening rib, can effectively ensure that the ring rigidity of winding pipe satisfies the actual engineering demand.
Because the winding pipe generally needs to be applied with a longer pipe length in practical application, the arrangement mode of each reinforcing rib in the technology is as follows: the distance between two adjacent reinforcing ribs on the same outer pipe layer is equal, the distance is A, and the distance between the reinforcing ribs on two sides of the winding lap joint of the outer pipe layer is equal to A. After adopting the design of above-mentioned mode, each strengthening rib also is spiral winding on the winding pipe after its shaping, and the interval between each strengthening rib also equals, and this mode arranges each strengthening rib, and it can provide even supporting effect to whole body, and when the winding pipe was used, each part was when bearing external force, and is more even, and ring rigidity is better.
Example 2
On the basis of embodiment 1, in order to further improve the comprehensive performance of the winding drain pipe, in this embodiment, the structure of the winding drain pipe is further optimized, as shown in fig. 1, on one hand, the structural shape of the reinforcing ribs is optimized, and the cross section of each reinforcing rib is divided into a root part integrated with the outer pipe layer and a head part located above the root part, wherein the root part and the head part are respectively configured into a rectangular shape and an umbrella shape, and the diameter of the umbrella part is greater than the width of the rectangular part. The design is carried out by adopting the mode, and the umbrella-shaped head part is adopted, so that the anti-collision device has stronger anti-collision capability in the application of the winding pipe, is not easy to be collided by hard objects such as external stones and the like, prevents the steel belt in the reinforcing rib from being exposed, and can improve the external protection to the steel belt; meanwhile, the slightly larger umbrella-shaped head is favorable for relieving the stress concentration of the head of the reinforcing rib, and the reliability of the whole reinforcing rib after being formed is higher.
On the other hand, under the condition that has designed the strengthening rib, for further promoting the ring rigidity of winding drain pipe, still select adjacent two in this technique outer pipe layer between the strengthening rib surface on integrated into one piece have two enhancement ribs, and the hoop diameter of this enhancement rib slightly is greater than the external diameter of winding drain pipe, adds at each enhancement rib and holds down, and each enhancement rib can further promote the ring rigidity of winding pipe, and each the enhancement rib is followed the lengthwise central line direction on outer pipe layer arranges to the realization is after whole winding drain pipe shaping, by each strengthening rib and the crisscross each other of enhancement rib arrange down, compare in current winding pipe, can promote the ring rigidity of winding pipe by a wide margin, promote its life.
