[0005] To achieve the above object, the technical solution of the utility model is realized as follows: A reinforced fiberglass pipe, comprising:

[0006] A fiberglass pipe body;

[0007] A flexural member, connected to the outer periphery of the fiberglass pipe body; the flexural member includes a flexural plate, the flexural plate is an arc-shaped plate and extends along the length direction of the fiberglass pipe body and then is connected to the fiberglass pipe body.

[0008] Further, a plurality of the flexural plates are provided, and the plurality of flexural plates are equidistantly distributed along the circumferential direction of the fiberglass pipe body.

[0009] Further, the concave surface of the flexural plate faces the fiberglass pipe body.

[0010] Further, the flexural member further includes a connecting ring; the connecting ring is sleeved on the fiberglass pipe body, and a plurality of the connecting rings are arranged along the length direction of the fiberglass pipe body, and the connecting ring connects the flexural plate and the fiberglass pipe body.

[0011] Further, a buffer layer is laid between the connecting rings; the buffer layer is wrapped around the fiberglass pipe body.

[0013] Further, a wear-resistant shell is sleeved outside the flexural member, and the wear-resistant shell is connected to the flexural member.

[0014] Further, a heat preservation strip is filled between the flexural plate and the connecting ring.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] For the reinforced fiberglass pipe of the utility model, by providing a folding resistance member and connecting the folding resistance member to the outer periphery of the fiberglass pipe body, the strength of the fiberglass pipe body is improved; the folding resistance plate extends along the length direction of the fiberglass pipe body. When the fiberglass pipe body is under external heavy pressure, the folding resistance plate with an arc-shaped plate structure reduces the possibility of the fiberglass pipe body being bent, improves the strength of the fiberglass pipe body, and further improves the service life of the fiberglass pipe body.

[0017] Secondly, multiple folding resistance plates are provided, and the multiple folding resistance plates are distributed circumferentially along the fiberglass pipe body. The folding resistance plates located on the upper and lower sides of the fiberglass pipe body improve the compressive and folding resistance capabilities of the fiberglass pipe body; the anti-extrusion and folding resistance capabilities of the left and right sides of the fiberglass pipe body; at the same time, in cooperation with the connecting rings, when the folding resistance plate is subjected to an extrusion force, the force is transmitted to the connecting rings through the folding resistance plate and dispersed to each connecting ring, reducing the extrusion force received by the fiberglass pipe body.

[0018] In addition, when it is assumed that the folding resistance plate is bent and deformed under an extrusion force, by providing a buffer layer, it is avoided that the folding resistance plate directly contacts the fiberglass pipe body, so as to reduce the possibility that the folded folding resistance plate pierces the fiberglass pipe body, and improve the strength and service life of the fiberglass pipe.

[0027] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0028] Fiberglass pipes can be applied in multiple fields; due to their excellent corrosion resistance and high temperature resistance, which are difficult to replace by other materials, they can be applied in the chemical industry; due to their characteristics of light weight, high strength, and low thermal conductivity, they can be applied in the construction industry; due to their good corrosion resistance, they can also be applied in the water treatment industry; at the same time, since they have less impact on the environment during the production and manufacturing process, they are also commonly used in the environmental protection industry. When it comes to underground drainage systems, fiberglass pipes have better corrosion resistance compared to traditional cast iron pipes. This embodiment relates to a reinforced fiberglass pipe to improve the strength of the fiberglass pipe and thus extend its service life.

[0029] In terms of the overall structure, the reinforced fiberglass pipe includes a fiberglass pipe body 1 and a flexure-resistant member 2, and the flexure-resistant member 2 is connected to the outer periphery of the fiberglass pipe body 1; the flexure-resistant member 2 includes a flexure-resistant plate 21, the flexure-resistant plate 21 is in the shape of an arc plate, and the flexure-resistant plate 21 extends along the length direction of the fiberglass pipe body 1 and then is connected to the fiberglass pipe body 1.

[0030] By providing the flexure-resistant member 2 and connecting the flexure-resistant member 2 to the outer periphery of the fiberglass pipe body 1, the strength of the fiberglass pipe body 1 is improved; the flexure-resistant plate 21 extends along the length direction of the fiberglass pipe body 1. When the fiberglass pipe body 1 is subjected to external heavy pressure, the arc-shaped plate structure of the flexure-resistant plate 21 reduces the possibility of the fiberglass pipe body 1 being bent, improves the strength of the fiberglass pipe body 1, and thus extends the service life of the fiberglass pipe body 1.

[0031] Based on the above overall introduction, the anti-folding plate 21 in this embodiment is as follows Figures 1 to 2 As shown, the anti-folding plate 21 is the same length as the FRP pipe body 1, and the concave surface of the anti-folding plate 21 faces the FRP pipe body 1. A plurality of anti-folding plates 21 are provided, and the plurality of anti-folding plates 21 are evenly distributed along the circumference of the FRP pipe body 1. The anti-folding plates 21 located on the upper and lower sides of the FRP pipe body 1 improve the compression resistance and anti-folding capacity of the FRP pipe body 1; the anti-folding plates 21 located on the left and right sides of the FRP pipe body 1 improve the anti-extrusion capacity and anti-folding capacity.

[0032] In order to facilitate the connection of multiple anti-bending plates 21 with the FRP pipe body 1 and reduce and disperse the force transmitted from the anti-bending plates 21 to the FRP pipe body 1 when the anti-bending plates 21 are subjected to external extrusion force. Figure 2 As shown, the anti-bending member 2 also includes a link 22 which is sleeved on the FRP pipe body 1 . A plurality of links 22 are arranged along the length direction of the FRP pipe body 1 . The link 22 connects the anti-bending plate 21 and the FRP pipe body 1 .

[0033] As an practicable method, the link 22 and the anti-bending plate 21 can be made of glass fiber reinforced plastics or stainless steel or other materials with a certain strength. The anti-bending member 2 itself has a certain strength and a certain impact resistance. As an practicable method, Figure 2 As shown, the links 22 are evenly distributed along the length direction of the FRP pipe body 1. When the anti-bending plate 21 is subjected to extrusion force, the force is transmitted to the links 22 through the anti-bending plate 21 and dispersed to each link 22, thereby reducing the extrusion force on the FRP pipe body 1. The evenly distributed links 22 make the FRP pipe body 1 more balanced in force, reduce the local force, and reduce the impact of external extrusion force on the FRP pipe body 1, thereby increasing the service life of the FRP pipe.

[0034] In order to prevent the anti-folding plate 21 from directly contacting the FRP pipe body 1 after being bent, a buffer layer 3 is laid between the links 22, and the buffer layer 3 is wrapped around the FRP pipe body 1. As an implementable method, the buffer layer 3 is made of rubber as a raw material. Of course, the buffer layer 3 can also be made of a flexible material with a certain elasticity and not easily punctured. For example, it is made of silicone as a raw material. When it is assumed that the anti-folding plate 21 is bent and deformed by the extrusion force, the buffer layer 3 is provided to prevent the anti-folding plate 21 from directly contacting the FRP pipe body 1, so as to reduce the possibility of the anti-folding plate 21 puncturing the FRP pipe body 1 after being bent, thereby improving the strength and service life of the FRP pipe.

[0035] In order to reduce the influence of the external environmental temperature on the materials conveyed in the glass steel pipe body 1, a heat preservation strip 5 is filled between the folding-resistant plate 21 and the connecting ring 22. The heat preservation strip 5 is connected to the folding-resistant plate 21 and is embedded in the folding-resistant plate 21. As an implementable way, the heat preservation strip 5 can be made of rock wool as the raw material, or can be made of polyurethane or the like as the raw material, and has the characteristics of light weight, good heat insulation performance and easy availability.

[0036] A wear-resistant shell 4 is sleeved outside the folding-resistant member 2, and the wear-resistant shell 4 is connected to the folding-resistant member 2. As an implementable way, the wear-resistant shell 4 is of a circular tubular structure, sleeved outside the folding-resistant member 2, and fixedly connected to the convex rib of the folding-resistant plate 21. The specific connection method is determined according to the materials of the folding-resistant plate 21 and the wear-resistant shell 4. The wear-resistant shell 4 can be made of glass fiber reinforced plastic as the raw material or can be made of stainless steel as the raw material. When both the folding-resistant plate 21 and the wear-resistant shell 4 are made of glass fiber reinforced plastic as the raw material, the folding-resistant plate 21 and the wear-resistant shell 4 can be connected by an adhesive method. When the folding-resistant plate 21 and the wear-resistant shell 4 are made of stainless steel as the raw material, the folding-resistant plate 21 and the wear-resistant shell 4 are connected by a welding method.

[0037] The wear-resistant shell 4 is the same length as the glass steel pipe body 1. When the glass steel pipe body 1 is buried underground for use, the wear-resistant shell 4 reduces the abrasion caused to the glass steel pipe body 1 by dragging the glass steel pipe during construction. After the construction is completed, the wear-resistant shell 4 reduces the pressure of the covering on the folding-resistant member 2 and the glass steel pipe body 1, achieving the effects of improving the strength of the glass steel pipe and extending the service life of the glass steel pipe.

[0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
