An electrically flexible protection tube

Abstract

This utility model relates to the field of power protection pipe technology, and more particularly to a flexible power protection pipe. The flexible power protection pipe provided by this utility model solves the technical problem of poor flexibility in existing power protection pipes. A flexible power protection pipe includes a pipe body and a connector. By setting transverse reinforcing ribs, with gaps between the transverse and longitudinal reinforcing ribs, and with the transverse reinforcing ribs evenly distributed along the length of the pipe body, when geological conditions change, such as sinking or rising, the pipe body is required to bend to a certain extent. At this time, the gaps between the transverse and longitudinal reinforcing ribs allow the pipe body to bend to adapt to changes in geological conditions when the longitudinal reinforcing ribs undergo a certain bending deformation. Alternatively, during construction in curved sections, bending of the longitudinal reinforcing ribs can cause the pipe body to bend, effectively adapting to the construction environment of curved sections.

Description

Technical Field

[0001] This utility model relates to the field of power protection pipe technology, and in particular to a flexible power protection pipe. Background Technology

[0002] Power protection pipes are conduits installed outside cables to protect them. They are typically used underground, meaning that underground cables require power protection pipes to be installed outside the cables during installation to prevent damage and improve safety. Therefore, power protection pipes are widely used in underground cable laying projects.

[0003] However, during the construction of power protection pipes, considering changes in geological conditions or the construction environment, power protection pipes usually need to have one or more bends. Alternatively, when geological conditions change, power protection pipes should have a certain degree of bending performance to prevent deformation or breakage.

[0004] In existing technologies, bending pipes are used to construct the curved sections. However, when geological conditions change, the strength of the power protection pipe is relied upon to adapt to the geological changes. In other words, the power protection pipes in existing technologies have poor flexibility and cannot compensate for the deformation caused by geological changes.

[0005] Therefore, existing power protection pipes suffer from poor flexibility. Summary of the Invention

[0006] This utility model provides a flexible power protection tube, which solves the technical problem of poor flexibility in existing power protection tubes.

[0007] Some implementation schemes for solving the above-mentioned technical problems include:

[0008] A flexible power protection tube, comprising a tube body;

[0009] and connector, the connector connecting the two ends of the tube body;

[0010] The tube body is provided with longitudinal reinforcing ribs, the length direction of the longitudinal reinforcing ribs is parallel to the length direction of the tube body, and the longitudinal reinforcing ribs are evenly distributed in the tube body along the circumference of the tube body;

[0011] The tube body is also provided with transverse reinforcing ribs, which are annular and evenly distributed along the length of the tube body. Furthermore, there is a gap between the transverse reinforcing ribs and the longitudinal reinforcing ribs.

[0012] The connector is installed on the tube along the diameter direction of the tube body and connects the tube bodies spliced ​​end to end.

[0013] Preferably, the tube body is provided with a fixing groove for fixing the transverse reinforcing rib, and at least a portion of the transverse reinforcing rib is located in the fixing groove.

[0014] Preferably, the depth of the fixing groove is not less than the width of the fixing groove.

[0015] Preferably, the fixing groove is disposed on the outer wall of the pipe body, or the fixing groove is disposed on the inner wall of the pipe body.

[0016] Preferably, the transverse reinforcing rib is bonded to the fixing groove, or the transverse reinforcing rib is welded to the fixing groove.

[0017] Preferably, the cross-sectional shape of the transverse reinforcing rib is semi-circular, or rectangular, or polygonal.

[0018] Preferably, there is a gap between the sidewall of the transverse reinforcing rib and the sidewall of the fixing groove.

[0019] Preferably, the longitudinal reinforcing rib has a circular cross-sectional shape, or the longitudinal reinforcing rib has a regular polygonal cross-sectional shape. There are two layers of longitudinal reinforcing ribs, which are arranged along the diameter direction of the tube body. The longitudinal reinforcing ribs are spirally arranged in the tube body, and the spiral directions of adjacent layers of longitudinal reinforcing ribs are opposite.

[0020] Preferably, the connector includes a collar disposed at one end of the tube body, and a sleeve disposed at the other end of the tube body. The sleeve mates with the collar. The connector also includes a insert. The collar is provided with a slot that mates with the insert. The slot passes through the collar. The sleeve is provided with a positioning groove that mates with the insert. The insert passes through the slot and mates with the positioning groove.

[0021] Preferably, there are two inserts, which are fixed together by bolts. Each insert has a protrusion that protrudes from the insert along the diameter of the tube. The bolts are located on the protrusions. The collar and the tube are integrally formed. The sleeve and the tube are integrally formed.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] By incorporating transverse reinforcing ribs with gaps between them and the longitudinal reinforcing ribs, and by uniformly distributing the transverse reinforcing ribs along the length of the pipe, the pipe can bend to a certain extent when geological conditions change, such as during subsidence or ascent. The gaps between the transverse and longitudinal reinforcing ribs allow the pipe to bend in response to these changes, adapting to the altered geological conditions. Alternatively, during construction in curved sections, bending the longitudinal reinforcing ribs can induce bending in the pipe, effectively adapting to the construction environment in curved areas.

[0024] By incorporating transverse and longitudinal reinforcing ribs, the pipe body possesses high strength and is not easily damaged. Furthermore, due to the gap between the transverse and longitudinal reinforcing ribs, the longitudinal reinforcing ribs independently bear bending forces, giving the pipe body a certain degree of flexibility. This allows for some bending deformation of the pipe body without affecting its performance.

[0025] The connector is installed on the pipe along the diameter direction. Since the pipe may be bent during construction, the connector is installed on the pipe along the diameter direction, which makes the pipe easier to construct. When splicing the ends of the pipe, it is not necessary to rotate the pipe for assembly, thus optimizing the construction performance of the flexible power protection pipe.

[0036] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0037] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0038] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] Reference Figures 1 to 6 As shown, a flexible power protection tube includes a tube body 1;

[0040] and connector 2, which connects the tube body 1 spliced ​​end to end;

[0041] The tube body 1 is provided with longitudinal reinforcing ribs 11, the length direction of the longitudinal reinforcing ribs 11 is parallel to the length direction of the tube body 1, and the longitudinal reinforcing ribs 11 are evenly distributed in the tube body 1 along the circumference of the tube body 1.

[0042] The tube body 1 is also provided with a transverse reinforcing rib 12. The transverse reinforcing rib 12 is annular and is evenly distributed on the tube body 1 along the length direction of the tube body 1. Furthermore, there is a gap between the transverse reinforcing rib 12 and the longitudinal reinforcing rib 11.

[0043] The connector 2 is installed on the tube 1 along the diameter direction of the tube 1 and connects the tube 1 spliced ​​end to end.

[0044] The flexibility in a power flexible protection tube refers to the ability of the tube body 1 to bend to a certain extent, meaning that the performance of the tube body 1 is not affected after bending to a certain degree. Typically, the bending range of the tube body 1 is small; for example, a portion of the tube body 1 may bend by a few millimeters or centimeters.

[0045] In practice, since the length of the tube body 1 is usually quite long, and the longitudinal reinforcing disc also has a relatively long length, due to the rigidity of the material itself, when the length of the longitudinal reinforcing rib 11 is long, even if the longitudinal reinforcing rib 11 bends to a certain extent, it will not affect the performance of the tube body 1.

[0046] Understandably, since there is a gap between the longitudinal stiffener 11 and the transverse stiffener 12, the transverse stiffener 12 does not increase the strength of the longitudinal stiffener 11. Therefore, the longitudinal stiffener 11 is prone to deformation, giving the tube body 1 a certain degree of flexibility.

[0047] Understandably, since the longitudinal stiffeners 11 and the transverse stiffeners 12 form a grid structure on the orthographic projection plane, when a force is applied to the pipe body 1 along the diameter direction, the longitudinal stiffeners 11 and the transverse stiffeners 12 simultaneously bear the force, and the pipe body 1 still has high strength.

[0048] In some embodiments, the tube body 1 is provided with a fixing groove 13 for fixing the transverse reinforcing rib 12, and at least a portion of the transverse reinforcing rib 12 is located in the fixing groove 13.

[0049] The transverse reinforcing rib 12 is used to withstand the force applied along the diameter of the pipe body 1. Therefore, the transverse reinforcing rib 12 can be fixed to the pipe body 1 or not. It is only necessary to fit the transverse reinforcing rib 12 onto the pipe body 1. Of course, it is more convenient to construct the flexible power protection pipe when the transverse reinforcing rib 12 is fixed to the pipe body 1.

[0050] In some embodiments, the depth of the fixing groove 13 is not less than the width of the fixing groove 13.

[0051] Reference Figures 1 to 6 As shown, in some embodiments, the fixing groove 13 is disposed on the outer wall of the tube body 1, or the fixing groove 13 is disposed on the inner wall of the tube body 1.

[0052] In some embodiments, the transverse reinforcing rib 12 is bonded to the fixing groove 13, or the transverse reinforcing rib 12 is welded to the fixing groove 13.

[0053] In some embodiments, the cross-sectional shape of the transverse reinforcing rib 12 is semi-circular, or the cross-sectional shape of the transverse reinforcing rib 12 is rectangular, or the cross-sectional shape of the transverse reinforcing rib 12 is polygonal.

[0054] In some embodiments, there is a gap between the sidewall of the transverse reinforcing rib 12 and the sidewall of the fixing groove 13.

[0055] There is a gap between the side wall of the transverse reinforcing rib 12 and the side wall of the fixing groove 13. When the tube body 1 bends, the side wall of the fixing groove 13 will not interfere with the transverse reinforcing rib 12, thereby making the tube body 1 easier to bend and giving the tube body 1 better flexibility.

[0056] Reference Figures 1 to 6 As shown, in some embodiments, the longitudinal reinforcing rib 11 has a circular cross-sectional shape, or the longitudinal reinforcing rib 11 has a regular polygonal cross-sectional shape. The longitudinal reinforcing rib 11 has two layers, and the two layers of longitudinal reinforcing rib 11 are arranged along the diameter direction of the tube body 1. The longitudinal reinforcing rib 11 is spirally arranged inside the tube body 1, and the spiral directions of adjacent two layers of longitudinal reinforcing rib 11 are opposite.

[0057] Understandably, the fact that the longitudinal reinforcing rib 11 is parallel to the length direction of the tube body 1 means that the overall length direction of the longitudinal reinforcing rib 11 is parallel to the length direction of the tube body 1.

[0058] When the longitudinal reinforcing ribs 11 are arranged in a spiral shape inside the tube body 1, the longitudinal reinforcing ribs 11 form a grid-like structure inside the tube body 1, giving the tube body 1 higher strength. At the same time, because the longitudinal reinforcing ribs 11 are spiral, the tube body 1 can still bend to a certain extent, giving the tube body 1 good flexibility.

[0059] Reference Figures 1 to 6 As shown, in some embodiments, the connector 2 includes a collar 21 disposed at one end of the tube body 1, and the connector 2 also includes a sleeve 22 disposed at the other end of the tube body 1. The sleeve 22 cooperates with the collar 21. The connector 2 also includes a insert 23. The collar 21 is provided with a slot 211 that cooperates with the insert 23. The slot 211 passes through the collar 21. The sleeve 22 is provided with a positioning groove 221 that cooperates with the insert 23. The insert 23 passes through the slot 211 and cooperates with the positioning groove 221.

[0060] Reference Figures 1 to 6 As shown, in some embodiments, there are two inserts 23, which are fixed by bolts 232. Each insert 23 has a protrusion 231 that protrudes from the insert 23 along the diameter of the tube body 1. The bolts 232 are disposed on the protrusion 231. The collar 21 and the tube body 1 are integrally formed. The sleeve 22 and the tube body 1 are integrally formed.

[0061] In some embodiments, the connector 2 may also take other forms, for example, by directly fixing the end-to-end tube 1 with screws, the axis of the screws being perpendicular to the axis of the tube 1.

[0062] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0063] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0064] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
