Description

Technical Field

[0001] This utility model relates to the field of power protection pipe technology, and in particular to an MPP power protection pipe for classifying cables. Background Technology

[0002] MPP pipe, also known as MPP power cable protection pipe, is divided into open-cut and trenchless types. Trenchless MPP pipe is also called MPP jacking pipe or drag pipe. MPP pipe uses modified polypropylene as the main raw material. It has the characteristics of high temperature resistance and external pressure resistance, and is suitable for medium and low voltage power transmission cable ducts below 10KV.

[0003] Searching revealed that existing MPP power protection pipes already have cable classification structures. However, after long-distance laying, cables need to be inserted into these pipes. Since each pipe is an individual unit, the internal partition structure is prone to misalignment, which is not conducive to cable insertion. Therefore, an MPP power protection pipe with cable classification capability is needed to meet this requirement. Summary of the Invention

[0004] The purpose of this invention is to provide an MPP power protection tube for classifying cables, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an MPP power protection pipe for classifying cables, comprising a pipe body and a connector pipe. A partition plate is provided inside the pipe body, the partition plate being arranged in a cross shape along the axial direction of the pipe body. The thickness and length of each branch of the partition plate are the same. The partition plate and the inner wall of the pipe body are separated into four chambers for classifying and placing cables. The connector pipe is sleeved on one end of the pipe body. A connecting plate is provided inside the connector pipe, the connecting plate being arranged in a cross shape along the axial direction of the connector pipe, and a insertion groove is provided on the connecting plate. An insertion plate is provided at the end of the partition plate, and the insertion plate is inserted into the insertion groove.

[0006] Preferably, the pipe body, connector pipe, partition plate, connecting plate and plug plate are all made of modified polypropylene, and the pipe body, partition plate and plug plate are integrally formed, and the connector pipe and connecting plate are integrally formed.

[0007] Preferably, the diameter of the two ends of the connector tube is the same as the outer diameter of the tube body, and the diameter of the middle part of the connector tube is the same as the inner diameter of the tube body.

[0008] Preferably, the thickness of each branch of the partition plate and the connecting plate is the same, and the length of the connecting plate is the same as the length of the middle section of the connector pipe.

[0009] Preferably, both the insertion slot and the insertion plate are cross-shaped, with each branch of the insertion slot arranged along each branch of the connecting plate, and each branch of the insertion plate arranged along each branch of the partition plate.

[0010] Preferably, the depth of the insertion slot is the same as the length of the connecting plate, and the length of the insertion plate is less than half the depth of the insertion slot.

[0011] The beneficial effects of this utility model are:

[0012] In this invention, the partition plate is used to form multiple chambers inside the tube, allowing multiple cables to be inserted into a single tube, thereby achieving the effect of classified placement.

[0013] In this invention, the cooperation between the connecting plate, the plug slot, and the plug plate allows the plug plate to be inserted into the plug slot when two separate tubes are connected via the connector tube. This achieves the alignment of the partition plates within the two separate tubes, thereby ensuring the alignment of each chamber, facilitating cable insertion, and effectively avoiding misalignment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3An MPP power protection pipe for classifying cables includes a pipe body 1 and a connector pipe 2. A partition plate 3 is provided inside the pipe body 1. The partition plate 3 is arranged in a cross shape along the axial direction of the pipe body 1. The thickness and length of each branch of the partition plate 3 are the same. The partition plate 3 and the inner wall of the pipe body 1 are divided into four chambers for classifying and placing cables. The connector pipe 2 is sleeved on one end of the pipe body 1. A connecting plate 4 is provided inside the connector pipe 2. The connecting plate 4 is arranged in a cross shape along the axial direction of the connector pipe 2, just like the partition plate 3. A plug-in groove 5 is opened on the connecting plate 4. A plug-in plate 6 is provided at the end of the partition plate 3. The plug-in plate 6 is inserted into the plug-in groove 5.

[0020] By setting the partition plate 3, the internal space of the tube body 1 is divided into multiple chambers, allowing multiple cables to be inserted into a single tube body 1, thus achieving the effect of classified placement. Through the cooperation between the connecting plate 4, the insertion slot 5, and the insertion plate 6, when two separate tube bodies 1 are connected via the connector tube 2, the insertion plate 6 can be inserted into the insertion slot 5, thereby achieving the alignment effect of the partition plates 3 in the two separate tube bodies 1, thus ensuring the alignment effect of each chamber, facilitating cable insertion, and effectively avoiding the problem of misalignment.

[0021] Specifically, in this embodiment, the materials of the pipe body 1, connector pipe 2, partition plate 3, connecting plate 4 and plug plate 6 are all modified polypropylene. The pipe body 1 is integrally formed with the partition plate 3 and plug plate 6, and the connector pipe 2 and connecting plate 4 are integrally formed, ensuring the overall effect of the pipe body 1, partition plate 3 and plug plate 6, as well as the overall effect of the connector pipe 2 and connecting plate 4.

[0022] Specifically, in this embodiment, the diameter of the two ends of the connector tube 2 is the same as the outer diameter of the tube body 1, and the diameter of the middle part of the connector tube 2 is the same as the inner diameter of the tube body 1. This facilitates the connection of the connector tube 2 with two independent tube bodies 1, while avoiding the step problem between the connector tube 2 and the inner wall of the tube body 1, and ensuring the smoothness of cable insertion.

[0023] Specifically, in this embodiment, the thickness of each branch of the partition plate 3 and the connecting plate 4 is the same, and the length of the connecting plate 4 is the same as the length of the middle tube of the connector tube 2, so as to avoid steps and gaps between the partition plate 3 and the connecting plate 4 and ensure the smoothness of cable insertion.

[0024] Specifically, in this embodiment, both the plug slot 5 and the plug plate 6 are cross-shaped. Each branch of the plug slot 5 is arranged along each branch of the connecting plate 4, and each branch of the plug plate 6 is arranged along each branch of the partition plate 3, thereby improving the matching degree between the plug plate 6 and the plug slot 5.

[0025] Specifically, in this embodiment, the depth of the insertion slot 5 is the same as the length of the connecting plate 4, and the length of the insertion plate 6 is less than half the depth of the insertion slot 5, so as to ensure that the insertion plates 6 on the two separate tubes 1 can be inserted into the two sides of the insertion slot 5 respectively.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
