It is made of heavy glass fiber with a resin matrix wound layer by layer on a rotating core mold according to process requirements, and quartz sand is evenly spread between the fibers at a long distance as a sand layer.

[0003] When the FRP pipe is in use, it does not have the anti-impact function, which causes the FRP pipe to be damaged or broken when it is impacted by the outside world, making it impossible to use the FRP pipe normally. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high-impermeability continuously wound FRP pipe, which has the advantages of having an anti-impact function for the FRP pipe, and solves the problem that the FRP pipe does not have an anti-impact function.

[0005] The high-impermeability continuously wound FRP pipe of the utility model comprises a FRP pipe body, four protective plates are arranged on the outer side of the FRP pipe body, and the four protective plates are arranged in a ring shape with respect to the center point of the FRP pipe body, eleven rubber shock-absorbing pads are arranged on the side of the protective plate corresponding to the FRP pipe body, and the inner sides of the eleven rubber shock-absorbing pads are fixed on the surface of the FRP pipe body at equal distances, the inner cavity sleeve of the rubber shock-absorbing pad is provided with a connecting rod, the inner side of the connecting rod is fixedly connected to a limiting plate, and the outer side of the connecting rod is fixedly connected to the protective plate. When the FRP pipe body is subjected to external impact protection, the utility model firstly protects the impact force through the protective plate, and transmits the impact force to the connecting rod through the protective plate. At this time, the connecting rod will expand and contract in the rubber shock-absorbing pad, and the impact force is transmitted to the limiting plate through the connecting rod. When the limiting plate moves and contacts the rubber shock-absorbing pad, the impact force can be reduced by the rubber shock-absorbing pad.

[0006] The utility model discloses a high-impermeability continuously wound glass fiber reinforced plastic pipe, wherein the inner side of the connecting rod and the connection point of the limiting plate are fixedly connected by an adhesive, and the inner side of the connecting rod is located at the center of the outer side of the limiting plate.

[0007] The utility model discloses a high-impermeability continuously wound FRP pipe, wherein the FRP pipe body consists of a base layer, an impermeability layer and a wear-resistant layer, the wear-resistant layer is located on the surface of the impermeability layer, and the impermeability layer is located on the surface of the base layer.

[0008] The utility model discloses a high-impermeability continuously wound FRP pipe, wherein the material of the impermeability layer is an epoxy ceramic layer, and the thickness of the impermeability layer is 0.11-0.12mm. The utility model can play an impermeability role on the FRP pipe body through the impermeability layer, so that the FRP pipe body has a better effect when in use, avoiding the situation that the FRP pipe body cannot be used normally due to penetration during use.

[0009] The utility model discloses a high-impermeability continuously wound FRP pipe, wherein the material of the wear-resistant layer is an epoxy furan coating layer, and the thickness of the wear-resistant layer is 0.12-0.13mm. The wear-resistant layer can provide wear resistance to the FRP pipe body, so that the FRP pipe body has a better effect when in use, avoiding severe wear of the FRP pipe body during long-term use, which leads to the situation that the FRP pipe body cannot be used normally.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. When the FRP pipe body is subjected to external impact protection, the utility model first protects against the impact force through the protective plate, and then transmits the impact force to the connecting rod through the protective plate. At this time, the connecting rod will expand and contract in the rubber shock-absorbing pad, and the impact force is transmitted to the limit plate through the connecting rod. When the limit plate moves and contacts the rubber shock-absorbing pad, the impact force can be reduced through the rubber shock-absorbing pad.

[0012] 2. The utility model can play an anti-seepage role on the FRP pipe body through the anti-seepage layer, so that the FRP pipe body has a better effect when in use, avoiding the situation that the FRP pipe body cannot be used normally due to the penetration of the FRP pipe body when in use;

[0013] The wear-resistant layer can provide the FRP pipe body with a wear-resistant effect, so that the FRP pipe body can be better used, avoiding severe wear of the FRP pipe body during long-term use, which may lead to the FRP pipe body being unable to be used normally.

When the FRP pipe body 1 is subjected to external impact protection, the utility model firstly protects the impact force through the protective plate 2, and transmits the impact force to the connecting rod 4 through the protective plate 2. At this time, the connecting rod 4 will expand and contract in the rubber shock-absorbing pad 3, and the impact force is transmitted to the limiting plate 5 through the connecting rod 4. When the limiting plate 5 moves and contacts the rubber shock-absorbing pad 3, the impact force can be reduced by the rubber shock-absorbing pad 3.
