Description

Technical Field

[0001] The utility model belongs to the technical field of communication pipes, and in particular relates to a pressure-resistant communication pipe. Background Art

[0002] Communication pipes, also known as underground communication cable protection pipes, are mainly installed in areas where communication cables and power lines intersect to prevent power lines from breaking and causing short circuits, which would cause communication cables and steel ropes to become electrified. This protects communication cables, switches, and movement boards, and even the entire machine from being burned out. It also has a certain isolation effect on the magnetic field interference of power lines, and is a commonly used pipe in modern cable laying projects.

[0003] Existing communication pipes are easily squeezed during installation and laying, causing damage to the communication pipes. In severe cases, the communication pipes may even rupture, thereby damaging the wires and cables inside the communication pipes and affecting signal transmission. Utility Model Content

[0004] The utility model aims to provide a pressure-resistant communication tube, which is used to solve the problem that the existing communication tube is easily damaged by being squeezed during installation.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A pressure-resistant communication tube, comprising a communication tube body, the communication tube body comprising an inner tube and an outer tube, the inner tube is inserted into the outer tube, a plurality of partitions are arranged between the inner tube and the outer tube, the plurality of partitions are circumferentially arranged around the axis of the inner tube, and are all fixedly connected to the outer wall of the inner tube, and a buffer structure is arranged between two adjacent partitions;

[0007] The buffer structure comprises an arc-shaped support plate, two sides of which are respectively supported on the side walls of the partition plate, and a back arc structure of the arc-shaped support plate is in contact with the inner wall of the outer tube.

[0008] Preferably, a limiting groove is provided on the side wall of the partition along the length direction of the partition, and the two sides of the arc-shaped support plate are respectively engaged in the limiting groove. This arrangement facilitates the installation of the arc-shaped support plate, and at the same time, the limiting groove limits the radial displacement of the arc-shaped support plate relative to the communication tube body, so that the arc-shaped support plate is supported on the two partitions when the communication tube body is under pressure, thereby improving the buffering effect.

[0009] Preferably, an elastic support member is provided between the arc-shaped support plate and the inner tube. In this way, when external pressure acts on the communication tube body and squeezes the outer tube, the elastic support member provides a buffering effect on the arc-shaped plate, which has a simple structure and strong practicality.

[0010] Preferably, a fireproof foam is arranged between the arc-shaped support plate and the inner tube. In this way, when the communication tube is used for too long and the cables in the communication tube age and spontaneous combustion occurs, the fireproof foam can block the combustion in time.

[0011] Preferably, a filling material is arranged between the arc-shaped support plate and the outer tube, so as to fill the gap between the arc-shaped support plate and the outer tube, which is beneficial to improve the supporting effect of the arc-shaped support plate on the outer tube.

[0012] Preferably, grids are arranged at equal intervals along the length direction on the partition and / or the arc-shaped support plate. In this way, a certain bending margin is reserved for the communication pipe through the grid, so that the communication pipe can adapt to the inclination within 5° during installation, and a large amount of stress concentration will not be caused by the inclination, which facilitates installation.

[0013] Preferably, the elastic support members are a plurality of rubber pads, which are arranged between the inner wall and the outer wall of the arc-shaped support plate and are arranged at equal intervals along the length direction of the arc-shaped support plate. In this way, the rubber pads provide a buffering effect on the arc-shaped support plate when the communication tube is under pressure, which has a simple structure and strong practicality.

[0014] The utility model adopting the above technical solution has the following advantages:

[0015] 1. In this scheme, the communication tube is supported by an arc-shaped support plate. When the communication tube body is subjected to external extrusion during installation, the force is transmitted to the arc structure on the back of the arc-shaped support plate through the outer tube. At this time, the force is along the arc surface of the arc-shaped support plate, which has a tendency to make the arc-shaped support plate open and become a flat plate, and is extruded at the position where it contacts the two partitions. At this time, a triangular structure is formed between the point where the arc-shaped support plate is subjected to the pressure of the outer tube and the point where the arc-shaped support plate is extruded by the two partitions, and the compressive resistance is strong;

[0016] 2. In this solution, a limiting groove is provided on the partition along the length direction of the partition, and the two sides of the arc-shaped support plate are clamped in the limiting groove, which is convenient for installing the arc-shaped support plate. At the same time, the limiting groove limits the radial displacement of the arc-shaped support plate relative to the communication tube body, so that the arc-shaped support plate is supported on the two partitions when the communication tube body is under pressure, thereby improving the buffering effect;

[0017] 3. In this solution, by setting a grid on the partition and / or the arc-shaped support plate, a certain bending margin is reserved for the communication pipe, so that the communication pipe can adapt to an inclination within 5° during installation, and will not cause excessive stress concentration due to the inclination, thereby facilitating installation.

[0027] like Figure 1 to Figure 4 As shown, a pressure-resistant communication tube of the utility model comprises a communication tube body 1, the communication tube body 1 comprises an inner tube 12 and an outer tube 11, the inner tube 12 is passed through the outer tube 11, a plurality of partitions 2 are arranged between the inner tube 12 and the outer tube 11, the plurality of partitions 2 are circumferentially arranged around the axis of the inner tube 12, and are all fixedly connected to the outer wall of the inner tube 12, and a buffer structure is arranged between two adjacent partitions 2.

[0028] During the installation of the communication pipe, when it is squeezed by the outside, the outer pipe 11 of the communication pipe is supported by the buffer structure, and the pressure is buffered to reduce the damage to the communication pipe.

[0029] In this embodiment, the buffer structure includes an arc-shaped support plate 3, both sides of which are supported on the side walls of the partition plate 2, and the back arc structure of the arc-shaped support plate 3 is in contact with the inner wall of the outer tube 11. When the communication tube body 1 is squeezed, the arc-shaped support plate 3 supports the outer tube 11 and provides a buffering effect, so that the communication tube body 1 has a strong anti-pressure effect.

[0030] In this embodiment, a fireproof foam 5 is arranged between the arc support plate 3 and the inner tube 12. When the communication tube is used for too long and the cables in the communication tube are aged and spontaneously combust, the fireproof foam 5 can block the combustion in time. A filling material 6 is arranged between the arc support plate 3 and the outer tube 11 to fill the gap between the arc support plate 3 and the outer tube 11 and improve the supporting effect of the arc support plate 3 on the outer tube 11. The filling material 6 can be one or a combination of chloroprene rubber, propylene rubber or silicone rubber.

[0031] In this embodiment, an elastic support member 4 is provided between the arc-shaped support plate 3 and the inner tube 12. When the outer tube 11 is squeezed, the elastic support member 4 provides a buffering effect on the arc-shaped plate, thereby improving the buffering effect.

[0032] In this embodiment, the elastic support member 4 is a plurality of rubber pads, which are arranged between the inner wall and the outer wall of the arc-shaped support plate 3 and are arranged at equal intervals along the length direction of the arc-shaped support plate 3. The rubber pads provide a buffering effect to the arc-shaped support plate 3 when the communication tube is under pressure, and the structure is simple and practical. It can be understood that the rubber pads can be embedded in the anti-slip foam, or the rubber pads can also be arranged so that the two ends are bonded and fixed to the inner wall of the arc-shaped support plate 3 and the outer wall of the inner tube 12 respectively.

[0033] In another embodiment of the present application, a plurality of elastic support members 4 are arranged at equal intervals along the length direction of the arc-shaped support plate 3, and the elastic support members 4 each include a telescopic guide column and a spring, the upper end of the telescopic guide column is fixedly connected to the inner wall of the arc-shaped support plate 3, the lower end of the telescopic guide column is fixedly connected to the outer wall of the inner tube 12, and the spring is sleeved on the telescopic guide column. The spring and the telescopic guide column provide a buffering effect on the arc-shaped support plate 3 when the communication tube is under pressure, and at the same time, the spring and the telescopic guide column provide a supporting effect on the arc-shaped support plate 3 under normal conditions.

[0034] In this embodiment, a limiting groove 21 is provided on the side wall of the partition 2 along the length direction of the partition 2, and the two sides of the arc-shaped support plate 3 are respectively clamped in the limiting grooves 21 on the adjacent partitions 2.

[0035] In this embodiment, grilles 7 are arranged at equal intervals along the length direction on the partition 2 and / or the arc-shaped support plate 3. The grilles 7 reserve a certain bending margin for the communication pipe, so that the communication pipe can adapt to an inclination within 5° during installation, and a large amount of stress concentration will not be caused due to the inclination, which facilitates installation and is beneficial to improving the structural strength of the communication pipe.

[0036] The principle of the present application is: when the communication tube body 1 is subjected to external extrusion during the installation process, the force is transmitted to the back arc structure of the arc-shaped support plate 3 through the outer tube 11. At this time, the force is along the arc surface of the arc-shaped support plate 3, and there is a tendency for the arc-shaped support plate 3 to open and become a flat plate, and is squeezed at the position in contact with the two partitions 2. At this time, the point where the arc-shaped support plate 3 is subjected to pressure from the outer tube 11 is point a, and the point where the arc-shaped support plate 3 is squeezed with the two partitions 2 is point b. A triangular structure is formed between point a and the two points b, and the pressure resistance is strong.
