Description

Technical Field

[0001] This utility model relates to the field of MPP pipe technology, specifically to an MPP pipe anti-deformation reinforcement structure. Background Technology

[0002] MPP pipe is a new type of plastic pipe widely used in the power industry, especially in cable protection, due to its excellent corrosion resistance, compressive strength, and lightweight properties. MPP pipes are typically buried underground or used in high-load environments during installation, effectively protecting cables from external environmental influences. However, in certain installation environments, MPP pipes may encounter external pressure, particularly under conditions of soil settlement, traffic loads, or equipment vibration, leading to varying degrees of compression. In such cases, the MPP pipe may deform or even break, affecting its normal function and service life. Therefore, enhancing the structural strength of MPP pipes and improving their deformation resistance has become a pressing technical challenge for the power industry.

[0003] Patent CN221929191U discloses a reinforced MPP cable protection pipe, including an MPP pipe body and: a cable support assembly disposed at the center of the inner cavity of the MPP pipe body, the cable support assembly being used for cable insertion and protection; and a support assembly, of which three are arranged in a ring around the inner wall of the MPP pipe body, one end of each support assembly being connected to the outer wall of the cable support assembly, the support assembly being used to strengthen the strength of the MPP pipe body. The cable support assembly includes a triangular frame disposed in the middle of the inner cavity of the MPP pipe body, the triangular frame having a triangular strip disposed in the middle of its inner cavity. This utility model can enhance the structural strength of the MPP cable protection pipe, thereby improving the deformation resistance of the MPP cable protection pipe, and thus improving the cable protection effect of the MPP cable protection pipe, so as to prevent cable damage.

[0004] The aforementioned existing technology uses a combination of support and reinforcement components to enhance the structural strength of the pipe body, thereby improving its resistance to deformation. However, this design has certain limitations. The combination of the support and reinforcement components almost completely fills the interior of the MPP pipe, significantly increasing the overall weight of the pipe, which causes inconvenience during handling and construction. Furthermore, the fixed reinforcement structure cannot be flexibly adjusted according to actual usage requirements, hindering adaptation to different construction environments and conditions. Therefore, based on these shortcomings, we propose an MPP pipe deformation-resistant reinforcement structure, aiming to reduce weight and improve flexibility while ensuring pipe strength, thus better adapting to the needs of actual construction. Utility Model Content

[0005] The purpose of this invention is to provide an anti-deformation reinforcement structure for MPP pipes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An MPP pipe deformation-resistant reinforcement structure includes an MMP pipe body, combined with... Figure 1 and Figure 2 As shown, the MMP pipe body serves as the main pipe structure, accommodating cables and providing basic structural support. The MMP pipe body contains an internal conduit for cable routing or as a mounting base for reinforcing components. Both ends of the external wall of the internal conduit are equipped with fixing components for securing it to the MMP pipe body. These two fixing components respectively fix the two ends of the internal conduit, thus fixing its position to the MMP pipe body. This facilitates easy disassembly and reassembly of the internal conduit before construction, allowing for adjustments to the reinforcement positions of multiple reinforcing components. The arc-shaped abutment plates can be reduced or eliminated in areas of the MMP pipe body where additional reinforcement is not required, thereby reducing the weight of the MMP pipe body and lowering costs.

[0008] Combination Figure 2 and Figure 4 As shown, the outer wall of the built-in conduit, located between two fixed components, is provided with multiple reinforcing components arranged equidistantly on the left and right. The reinforcing components enhance local pressure resistance through modular design. Each reinforcing component includes an annular fixing seat, which is integrally formed with the built-in conduit. The outer wall of the annular fixing seat is detachably connected to multiple support rods arranged in an annular array. The support rods are detachably adjustable through threaded connections to adapt to the reinforcement requirements of different pressure areas. The end of each support rod away from the annular fixing seat is provided with an arc-shaped abutment plate. The support rod and the arc-shaped abutment plate are integrally formed, and the convex surface of the arc-shaped abutment plate fits against the inner wall of the MMP tube body.

[0009] Construction workers adjust the number of support rods according to the actual construction location of the MMP pipe body. For example, if a certain part of the MMP pipe body may be under pressure after construction, the number of support rods is increased at the corresponding position on the inner wall of the MMP pipe body. This allows multiple arc-shaped abutments to support the pressure-bearing part of the MMP pipe body, enhancing its strength and preventing deformation. This reinforcement structure can be adjusted as needed for easy use by construction workers.

[0010] Preferred, such as Figure 5 As shown, the fixing assembly includes an annular fixing plate, the outer wall of which is attached to the inner wall of the MMP pipe body. The annular fixing plate achieves the initial positioning of the built-in conduit by attaching to the pipe wall.

[0011] The inner wall of the annular fixing plate is provided with four connecting rods arranged in a circular array. The end of the connecting rod away from the annular fixing plate is fixedly connected to the outer wall of the built-in conduit and bonded. The connecting rod is used to connect the annular fixing plate and the built-in conduit to form a stable support frame.

[0012] The inner wall of the annular fixing plate is provided with four internally threaded fixing tubes arranged in a ring array. The four internally threaded fixing tubes and four connecting rods are arranged in an alternating pattern. The internally threaded fixing tubes are threadedly connected to fixing bolts. The internally threaded fixing tubes and fixing bolts cooperate to provide a detachable fastening function.

[0013] The outer wall of the annular fixing plate is provided with a clearance hole for the fixing bolt to pass through. The clearance hole provides an installation channel for the fixing bolt and avoids structural interference. The threaded end of the fixing bolt passes through the clearance hole and abuts against the inner wall of the MMP pipe body, thereby fixing the position of the annular fixing plate and the MMP pipe body, and thus fixing the position of the built-in conduit and the MMP pipe body.

[0014] Preferred, such as Figure 4 As shown, the outer wall of the annular fixing seat has multiple threaded holes arranged in an annular array. The threaded holes cooperate with the threaded posts of the support rod to realize the flexible addition and removal of the support rod. The end of the support rod away from the arc-shaped abutment plate is provided with a threaded post. The threaded post is threadedly connected to the threaded hole. The threaded post ensures the stable installation of the support rod through the threaded connection.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The MPP pipe anti-deformation reinforcement structure combines detachable support rods with arc-shaped abutment plates. The reinforcement structure is only arranged in the pipe body parts that need reinforcement, avoiding the increase in overall pipe weight caused by the filling reinforcement in traditional technology. This reduces the difficulty of handling and construction, and saves material costs.

[0017] 2. The MPP pipe anti-deformation reinforcement structure allows for flexible adjustment of the number and position of support rods based on the pressure distribution in the actual construction environment. For example, in areas susceptible to soil settlement or traffic loads, the density of support rods can be increased to achieve precise local reinforcement and significantly improve the pipe's resistance to deformation.

[0018] 3. The MPP pipe features a deformation-resistant and reinforced structure. The fixing components, through the combination of a ring-shaped fixing plate and bolts, enable quick positioning and disassembly of the built-in conduit. Construction personnel can adjust the position of the built-in conduit or replace the reinforcing components as needed to adapt to the requirements of different engineering scenarios.

[0019] 4. The MPP pipe features a deformation-resistant and reinforced structure with an arc-shaped abutment plate that fits snugly against the inner wall of the pipe. This design evenly distributes external extrusion pressure throughout the pipe's circumference, preventing deformation or damage caused by localized stress concentration and extending the pipe's service life.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution:

[0028] An MPP pipe anti-deformation reinforcement structure includes an MMP pipe body 100, combined with... Figure 1 and Figure 2As shown, the MMP pipe body 100 serves as the main body of the pipe, used to accommodate cables and provide basic structural support. The MMP pipe body 100 has an internal conduit 200, which is used to run cables or as the installation base for reinforcing components. The left and right ends of the outer wall of the internal conduit 200 are provided with fixing components 400 for fixing the position of the MMP pipe body 100. The two fixing components 400 fix the positions of the two ends of the internal conduit 200 respectively, so that the internal conduit 200 is fixed to the position of the MMP pipe body 100. This makes it easy for construction personnel to disassemble and assemble the internal conduit 200 before construction, thereby facilitating the adjustment of the reinforcement positions of multiple reinforcing components 300. The arc-shaped abutment plate 330 is reduced or eliminated in the parts of the MMP pipe body 100 that do not require additional reinforcement, so as to reduce the weight of the MMP pipe body 100 and reduce costs.

[0029] Combination Figure 2 and Figure 4 As shown, multiple reinforcing components 300 are arranged equidistantly on the outer wall of the built-in conduit 200 and between the two fixing components 400. The reinforcing components 300 enhance local pressure resistance through modular design. The reinforcing components 300 include an annular fixing seat 310, which is integrally formed with the built-in conduit 200. Multiple support rods 320 arranged in an annular array are detachably connected to the outer wall of the annular fixing seat 310. The support rods 320 are detachably adjustable through threaded connection to adapt to the reinforcement requirements of different pressure areas. An arc-shaped abutment 330 is provided at the end of the support rod 320 away from the annular fixing seat 310. The support rod 320 and the arc-shaped abutment 330 are integrally formed. The convex surface of the arc-shaped abutment 330 fits against the inner wall of the MMP tube body 100.

[0030] Based on the actual construction location of the MMP pipe body 100, the construction personnel adjust the number of support rods 320. For example, if a certain part of the MMP pipe body 100 may be subjected to pressure after construction, then the number of support rods 320 is increased at the corresponding position on the inner wall of the MMP pipe body 100. This allows multiple arc-shaped abutments 330 to support the pressure-bearing position of the MMP pipe body 100, enhancing the strength of the MMP pipe body 100 and preventing deformation. This reinforcement structure can be adjusted as needed for easy use by construction personnel.

[0031] In this embodiment, as Figure 5 As shown, the fixing assembly 400 includes an annular fixing plate 410. The outer wall of the annular fixing plate 410 is attached to the inner wall of the MMP pipe body 100. The annular fixing plate 410 achieves the initial positioning of the built-in conduit 200 by attaching to the pipe wall.

[0032] The inner wall of the annular fixing plate 410 is provided with four connecting rods 440 arranged in a ring array. The end of the connecting rod 440 away from the annular fixing plate 410 is fixedly connected to the outer wall of the built-in conduit 200 and bonded. The connecting rod 440 is used to connect the annular fixing plate 410 and the built-in conduit 200 to form a stable support frame.

[0033] The inner wall of the annular fixing plate 410 is provided with four internally threaded fixing tubes 420 arranged in an annular array. The four internally threaded fixing tubes 420 and the four connecting rods 440 are arranged in an alternating pattern. The internally threaded fixing tubes 420 are threadedly connected to fixing bolts 430. The internally threaded fixing tubes 420 and the fixing bolts 430 cooperate to provide a detachable fastening function.

[0034] The outer wall of the annular fixing plate 410 is provided with a clearance hole 411 for the fixing bolt 430 to pass through. The clearance hole 411 provides an installation channel for the fixing bolt 430 and avoids structural interference. The threaded end of the fixing bolt 430 passes through the clearance hole 411 and abuts against the inner wall of the MMP pipe body 100, thereby fixing the position of the annular fixing plate 410 and the MMP pipe body 100, and thus fixing the position of the built-in conduit 200 and the MMP pipe body 100.

[0035] Specifically, such as Figure 4 As shown, the outer wall of the annular fixing seat 310 is provided with a plurality of threaded holes 311 arranged in an annular array. The threaded holes 311 cooperate with the threaded posts 321 of the support rod 320 to realize the flexible addition and removal of the support rod 320. The end of the support rod 320 away from the arc-shaped abutment 330 is provided with a threaded post 321. The threaded post 321 is threadedly connected to the threaded hole 311. The threaded post 321 ensures the stable installation of the support rod 320 through the threaded connection.

[0036] In this embodiment, the MPP pipe anti-deformation reinforcement structure is used by first installing support rods 320 on the corresponding reinforcing components 300 according to the predicted stress area of ​​the MMP pipe body 100. The threaded post 321 at the end of the support rod 320 is aligned with the threaded hole 311 on the annular fixing seat 310 and screwed in. If it is necessary to enhance the local compressive strength, the number of support rods 320 installed in that area can be increased; otherwise, the number of support rods 320 can be reduced or eliminated to reduce weight. Then, the built-in conduit 200 is inserted into the MMP pipe body 100 and fixed by the fixing components 40 at both ends. Positioning: Attach the annular fixing plate 410 to the inner wall of the MMP pipe body 100, then tighten the fixing bolts 430 so that the threaded end of the fixing bolts 430 abuts against the inner wall of the MMP pipe body 100, thus completing the fixing of the built-in conduit 200. At this time, the installed arc-shaped abutment plate 330 fits tightly against the inner wall of the MMP pipe body 100, providing support for the MMP pipe body 100. After construction, the arc-shaped abutment plate 330 prevents pipe deformation by dispersing external pressure, and the modular design of the built-in conduit 200 and the fixing component 400 facilitates subsequent maintenance or structural adjustment.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
