Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically to a pressure-resistant and supported MPP pipe. Background Technology

[0002] MPP pipe, also known as MPP power cable protection pipe, uses modified polypropylene as its main raw material. It eliminates the need for extensive dredging, excavation, and road surface damage, making it suitable for laying pipelines and cables in special locations such as roads, railways, buildings, and riverbeds. It can be widely used in municipal, telecommunications, power, gas, water supply, and heating pipeline projects. However, the existing MPP pipe materials have relatively simple internal and external structures, resulting in low external compression resistance during actual use. This makes the pipe susceptible to damage from transportation, dropping, impact, and external pressure, indirectly affecting the service life of the MPP pipe. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, a pressure-resistant MPP pipe is provided to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a pressure-resistant MPP pipe is provided, comprising: an inner tube, wherein a positioning plate, a buffer plate, and a base plate are symmetrically connected to the outer side of the inner tube, and a support plate is fixedly connected to the surface of the base plate; a positioning groove is provided on the inner side of the outer tube relative to the position of the positioning plate; the buffer plate and the support plate abut against the inner side of the outer tube; and a fixing column is fixedly connected to the inner side of the inner tube by a reinforcing plate.

[0005] Preferably, multiple sets of sliding grooves are formed at equal intervals around the inner arc surface of the inner tube in the circumferential direction, and the multiple sets of sliding grooves are all elongated strip structures, and the length of the sliding grooves is equal to the axial length of the inner tube.

[0006] Preferably, four sets of positioning plates are fixedly connected around the outer arc surface of the inner tube at equal intervals in the circumferential direction. The four sets of positioning plates are all elongated strips, and the length of the positioning plate is equal to the axial length of the inner tube. At the same time, the end face of the positioning plate is an isosceles trapezoidal structure.

[0007] Preferably, four sets of base plates are fixedly connected around the outer arc surface of the inner tube at equal intervals in the circumferential direction. The four sets of base plates are all elongated strip structures, and the length of the base plate is equal to the axial length of the inner tube. At the same time, the support plate fixedly connected to the surface of the base plate has a wave-shaped structure, and the crests and troughs of the support plate are both isosceles trapezoidal structures.

[0008] Preferably, eight sets of buffer plates are fixedly connected around the outer arc surface of the inner tube at equal intervals in the circumferential direction. The eight sets of buffer plates are all long strip structures, and multiple sets of through holes are evenly opened inside the buffer plates. The through holes are cylindrical structures.

[0009] Preferably, the fixing column has a cylindrical structure, and six sets of reinforcing plates are fixedly connected around the outer arc surface of the fixing column at equal intervals. The end of the reinforcing plate away from the fixing column is fixedly connected to a groove opened on the inner side of the inner tube.

[0010] Preferably, the length of the reinforcing plate is equal to the axial length of the fixed column, and the end face of the reinforcing plate has a Y-shaped structure, while the end face of the reinforcing plate away from the inner tube has an isosceles trapezoidal structure. At the same time, the inner cavity of the inner tube is evenly divided into multiple sets of wiring grooves by the reinforcing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the support plate, buffer plate and positioning plate symmetrically distributed between the outer tube and the inner tube can effectively enhance the structural strength between the outer tube and the inner tube, thereby effectively enhancing the compressive strength of the outer surface of the MPP tube. Furthermore, the combination of the fixing column and the reinforcing plate can effectively enhance the internal structural strength of the inner tube, thereby effectively enhancing the overall compressive support effect of the MPP tube, reducing the probability of damage to the MPP tube due to transportation, dropping, impact and external pressure, and ensuring that the MPP tube has a normal service life.

[0017] Reference Figures 1 to 4 As shown, this utility model provides a pressure-resistant MPP pipe, including: an inner tube 4, with a positioning plate 2, a buffer plate 3 and a base plate 6 symmetrically connected to the outer side of the inner tube 4, and a support plate 5 fixedly connected to the surface of the base plate 6. A positioning groove is opened on the inner side of the outer tube 1 relative to the position of the positioning plate 2. The buffer plate 3 and the support plate 5 abut against the inner side of the outer tube 1. At the same time, a fixing column 8 is fixedly connected to the inner side of the inner tube 4 through a reinforcing plate 7.

[0018] In this embodiment, the positioning plates symmetrically arranged on the outer side of the inner tube 4 and the corresponding positioning grooves on the inner side of the outer tube 1 are matched in size. This helps to enhance the stability of the connection between the outer tube 1 and the inner tube 4 after they are fitted together. The positioning plates 2 also provide corresponding auxiliary support for the outer tube 1. The buffer plates 3 and support plates symmetrically connected on the outer side of the inner tube 4 further enhance the structural strength between the outer tube 1 and the inner tube 4. When the outer surface of the outer tube 1 is impacted or squeezed, the support plates 5 and buffer plates 3 can provide corresponding auxiliary buffering against external forces, thus enhancing the compressive strength of the outer tube 1 against external forces. At the same time, the fixing columns 8 and reinforcing plates 7 arranged inside the inner tube 4 can effectively enhance the overall structural strength of the MPP tube through symmetrical multi-point support, thereby effectively enhancing the compressive strength of the MPP tube and providing good protection for the cables laid inside the inner tube 4.

[0019] As a preferred embodiment, multiple sets of sliding grooves are opened at equal intervals around the inner arc surface of the inner tube 4 in the circumferential direction, and the multiple sets of sliding grooves are all elongated structures, and the length of the sliding grooves is equal to the axial length of the inner tube 4.

[0020] In this embodiment, as Figure 1 The opening of the groove can help reduce the difficulty of connecting the outer tube 1 to the inner tube 4, and can also help enhance the stability of the connection between the outer tube 1 and the inner tube 4, avoiding the problem of relative rotation.

[0021] In a preferred embodiment, four sets of positioning plates 2 are fixedly connected around the outer arc surface of the inner tube 4 at equal intervals in the circumferential direction. The four sets of positioning plates 2 are all elongated strip structures, and the length of the positioning plate 2 is equal to the axial length of the inner tube 4. At the same time, the end face of the positioning plate 2 is an isosceles trapezoidal structure.

[0022] In this embodiment, as Figure 1 The structural design of the positioning plate 2 can effectively reduce the pressure exerted on the surface of the inner tube 4 by the force transmitted from the outer tube 1 to the inside, thereby effectively enhancing the compressive strength between the outer tube 1 and the inner tube 4. Furthermore, the dimensions of the positioning plate 2 and the slide groove are compatible, which can help improve the connection quality between the outer tube 1 and the inner tube 4.

[0023] In a preferred embodiment, four sets of base plates 6 are fixedly connected around the outer arc surface of the inner tube 4 at equal intervals in the circumferential direction. The four sets of base plates 6 are all elongated strip structures, and the length of the base plate 6 is equal to the axial length of the inner tube 4. Meanwhile, the support plate 5 fixedly connected to the surface of the base plate 6 has a wave-shaped structure, and the crests and troughs of the support plate 5 are both isosceles trapezoidal structures.

[0024] In this embodiment, as Figure 1 and Figure 2The structure of the support plate 5 can further enhance the stability of the connection between the outer tube 1 and the inner tube 4, and can also help enhance the impact resistance of the outer tube 1, and can correspondingly weaken the force on the outer tube 1.

[0025] In a preferred embodiment, eight sets of buffer plates 3 are fixedly connected around the outer arc surface of the inner tube 4 at equal intervals in the circumferential direction. The eight sets of buffer plates 3 are all long strip structures, and multiple sets of through holes are evenly opened inside the buffer plates 3. The through holes are cylindrical structures.

[0026] In this embodiment, as Figure 1 and Figure 3 The buffer plate 3 is made of hard rubber, and the through holes evenly opened inside the hard rubber can help enhance the deformation effect of the hard rubber under stress, thereby helping to weaken the force on the outer tube 1, improving the toughness of the appearance, and also helping to enhance the compressive support effect of the outer tube 1.

[0027] In a preferred embodiment, the fixing column 8 has a cylindrical structure, and six sets of reinforcing plates 7 are fixedly connected around the outer arc surface of the fixing column 8 at equal intervals. The end of the reinforcing plate 7 away from the fixing column 8 is fixedly connected to a groove opened on the inner side of the inner tube 4.

[0028] In this embodiment, as Figure 1 and Figure 2 The hollow structure of the fixing column 8 can effectively reduce the weight of the fixing column 8, thereby helping to reduce the overall weight of the MPP pipe. At the same time, the sliding groove opened on the inner side of the inner tube 4 can effectively improve the efficiency of the fixing column 8 and the reinforcing plate 7 installed inside the inner tube 4, and can also help enhance the stability of the connection between the reinforcing plate 7 and the inner tube 4. Furthermore, the number of reinforcing plates 7 can be flexibly adjusted according to actual needs.

[0029] In a preferred embodiment, the length of the reinforcing plate 7 is equal to the axial length of the fixing column 8, and the end face of the reinforcing plate 7 is Y-shaped, while the end face of the reinforcing plate 7 away from the inner tube 4 is isosceles trapezoidal. At the same time, the inner cavity of the inner tube 4 is evenly divided into multiple sets of wiring grooves by the reinforcing plate 7.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The structure of the reinforcing plate 7 allows the inner side of the inner tube 4 to have multiple symmetrically distributed support points, which can effectively enhance the structural strength of the inner tube 4 and thus help enhance the overall compressive strength of the MPP tube. In addition, the wiring grooves divided by the reinforcing plate 7 in the inner tube 4 can facilitate the classification of different types of cables and facilitate subsequent maintenance.

[0031] The MPP pipe of this utility model, through the cooperation of positioning plate 2, support plate 5, buffer plate 3, reinforcing plate 7 and fixing column 8, provides good compressive resistance between inner pipe 4 and outer pipe 1, thereby reducing the probability of accidental damage to the MPP pipe. At the same time, after the internal components of the MPP pipe are assembled, they are fixedly connected by corresponding fixing methods to ensure that the MPP pipe as a whole has good structural strength and enhances the compressive support effect of the MPP pipe.
