[0002] MPP pipe, also known as MPP power cable protection pipe, is available in trenchless and trenchless types. MPP trenchless pipe is also known as MPP jacking pipe or dragging pipe. MPP pipe is primarily made of modified polypropylene. It is resistant to high temperatures and external pressures and offers excellent electrical insulation. However, when buried underground, MPP pipe is susceptible to compression from excessive weight and can be inconvenient for cable threading. Utility Model Content

[0003] The purpose of the utility model is to provide a honeycomb MPP power cable protection tube with a simple structure, which is convenient for passing cables. Each cable is sheathed in a separate protection tube, and the protection tubes can be assembled into a honeycomb shape. It has good pressure resistance, strong practicality, and is suitable for promotion.

[0004] The utility model provides the following technical solution: a honeycomb MPP power cable protection tube, comprising an upper half tube and a lower half tube, the upper half tube and the lower half tube being symmetrical with each other, forming a tube with a regular hexagonal cross section when the upper half tube and the lower half tube are closed, the upper half tube and the lower half tube being provided with a plurality of bars, the lower end of the upper half tube being fixed with a symmetrical upper fixing bar, the upper end of the lower half tube being fixed with a symmetrical lower fixing bar, the upper surface of the lower fixing bar being fixed with a lower pressing bar, and the lower surface of the upper fixing bar being provided with a lower pressing groove matching the shape and position of the lower pressing bar;

[0005] The middle part of the upper half tube and the lower half tube is a plane wall, and concave edge grooves are provided on both sides of the plane wall. The shape of the edge groove matches the upper fixing bar and the lower fixing bar. The bottom of the edge groove is provided with a strip-shaped external card groove, and the upper and lower sides of the upper fixing bar and the lower fixing bar are fixed with external card strips that match the shape and position of the external card groove.

[0006] Preferably, the two side walls of the external card slot are convergent walls that converge toward the opening, and when the external card slot is combined with the external card strip, the upper and lower plane walls fit together.

[0007] Preferably, the opening of the lower pressing groove is a constricting opening, and the raised end of the lower pressing strip is pressed against the constricting opening.

[0008] Preferably, the upper half tube and the lower half tube are MPP tubes, the convergence opening is thin-walled, and the convergence wall located outside the plane wall is thin-walled. The thickness of the thin wall is sufficient for the MPP material to undergo elastic deformation for the outer clamping strip and the lower pressure strip to pass through.

[0009] The beneficial effects of the utility model are as follows: the structure is simple, and it is convenient to pass the cables. Each cable is sheathed in a separate protective tube, and the protective tubes can be assembled into a honeycomb shape, which has good pressure resistance and strong practicality. The specific effects are as follows:

[0010] (1) The utility model is provided with an upper fixing bar and a lower fixing bar. When laying the wires, the wires are placed on the lower half of the pipe. At this time, the upper half of the pipe is aligned with the two ends of the lower half of the pipe, and the upper fixing bar is pressed. The lower pressing groove of the upper fixing bar is pressed to the lower pressing bar of the lower fixing bar. The pressure can be started from one end of the upper half of the pipe. When the thickness of the pipe wall of the MPP material is low, it can undergo elastic deformation, so that the lower pressing bar can push open the constriction port and press into the lower pressing groove, and clamp the lower pressing bar through the constriction port, thereby forming a pipe with a regular hexagonal cross section. While providing stronger pressure resistance, it is convenient for the laying of wires in the pipe.

[0011] (2) The utility model is provided with an upper half tube and a lower half tube, and there are multiple upper half tubes and lower half tubes. After the wires are laid in the pipeline, each wire is sheathed in a separate protective tube, and the protective tubes can be assembled into a honeycomb shape. When assembling, the upper fixing strip or the lower fixing strip of the protective tube is inserted into the adjacent edge groove, and the outer card strip on it is pressed into the outer card groove of the edge groove. The outer card strip squeezes open the thin side wall of the outer card groove and undergoes elastic deformation to allow it to pass through. When the two protective tubes are combined with each other, the outer card grooves and the outer card strips on them are combined with each other, so that the two protective tubes are connected. Multiple protective tubes are spliced in a honeycomb shape. When subjected to heavy pressure, the protective tubes are separated to protect a single protective tube. The protective tubes can be assembled at will, and the protective tubes can be assembled into a more pressure-resistant structure. BRIEF DESCRIPTION OF THE DRAWINGS
