Technical Field

[0001] The utility model relates to the technical field of emergency rescue and optical fiber communication, and in particular to a skeleton-type rescue composite pipe which integrates emergency rescue oxygen supply and audio and video communication functions. Background Art

[0002] Emergency rescue sites are often small in space and complex in environment. Large rescue equipment and facilities are often difficult to reach the rescue site, and rescue personnel are required to bring firefighting tools to the scene. This requires focusing on solving the many shortcomings in oxygen supply, power supply, lighting, infrared thermal imaging search, audio and video transmission, tracking, and on-site command during emergency rescue. Designing a composite rescue pipe that integrates oxygen supply and information transmission in one light plays a vital role in improving emergency response time in the event of a disaster, gaining golden time for rescue, ensuring the safety of rescue personnel, and minimizing disaster losses.

[0003] According to the rescue needs, the focus is on considering the long-term, large-span, and large-space life support needs of fire rescue personnel, ensuring that fire rescue personnel can provide long-distance and long-term gas, water, and lighting guarantees after going deep into the disaster site, and providing reliable communication guarantees for rescue personnel, including infrared thermal imaging search, audio and video transmission, rear command, travel trajectory and other functions.

[0004] At present, to realize the three functions of gas transmission, signal collection and luminous rope indication, the rescue team members need to carry transmission air pipes, optical cables, electrical cables, two cables and an air pipe. The appearance is large and the weight is heavy, and the resistance during the dragging process is large, so it is difficult for a single soldier to quickly reach the rescue site.

[0005] Therefore, there is an urgent need for a composite pipe with a small diameter and light weight that integrates a gas transmission pipe and an optical cable to meet the above application requirements. Utility Model Content

[0006] In view of the above problems existing in the prior art, the utility model provides a skeleton-type rescue composite pipe which highly integrates a gas delivery pipe with cables and optical fibers, and has the advantages of light weight, small size and easy to carry.

[0007] The technical solution of the utility model to solve the above-mentioned technical problems is as follows: a skeleton-type rescue composite pipe, characterized in that it includes an air supply pipe located in the center of the skeleton-type rescue composite pipe, a support skeleton is arranged outside the air supply pipe, a plurality of skeleton grooves are evenly opened on the outer wall of the support skeleton, armored optical fibers, tensile elements and cables are respectively embedded in the plurality of skeleton grooves, a water-blocking tape wrapped around the armored optical fibers, tensile elements, cables and the support skeleton is arranged outside the support skeleton, and a flame-retardant outer sheath is arranged outside the water-blocking tape.

[0008] Furthermore, the plurality of skeleton grooves are evenly arranged along the circumference of the supporting skeleton, and the plurality of skeleton grooves are parallel to each other.

[0009] Furthermore, the air supply pipe and the supporting frame having the frame groove are an integrated structure.

[0010] Furthermore, a supporting frame having a frame groove is formed on the outer surface of the air supply pipe by extrusion molding.

[0011] Furthermore, the armored optical fiber and the cable are arranged relatively to each other on the supporting frame.

[0012] Furthermore, the armored optical fiber adopts a stainless steel threaded tube armored optical fiber, the number is one, with 2 cores or 4 cores; the number of cables is two.

[0013] Furthermore, the tensile element is made of round steel wire, FRP, aramid fiber or high-strength polyethylene.

[0014] Furthermore, the water-blocking tape is made of water-blocking yarn, polyester film tape or non-woven fabric.

[0015] Furthermore, the flame-retardant outer sheath is made of black flame-retardant PVC, PU or PE, and the flame-retardant outer sheath 7 is formed on the outer surface of the water-blocking tape by one-time extrusion molding.

[0016] Furthermore, the air supply tube is a medical oxygen tube.

[0017] The beneficial effects of the utility model are as follows: the utility model adopts a skeleton structure, and a supporting skeleton with multiple skeleton grooves is extruded outside the air delivery pipe, and then the cables, armored optical fibers and multiple tensile elements are embedded in the skeleton grooves in parallel, and fixed by wrapping with water-blocking tape, and finally the whole is extruded and molded in one time with flame-retardant material to form a flame-retardant outer sheath; it can protect the air delivery pipe and optical fiber from damage to the greatest extent, and at the same time, it can also minimize the volume of the product under the same pulling force, and the outer diameter of the skeleton composite pipe is only 13mm; the skeleton rescue composite pipe is light in weight, small in outer diameter, soft, and has excellent mechanical, physical and environmental properties.

[0018] The composite pipe of the utility model makes it possible for a single person to carry it at the rescue site, and is suitable for emergency rescue occasions such as fire rescue sites and various mine tunnels; it is light in weight and easy to operate, and at the fire rescue site, a single person can complete the carrying, deployment, and other operations, and a team can also implement long-distance erection in different terrain conditions. It can quickly, maneuverably and flexibly construct functions such as oxygen delivery for personnel search and rescue, on-site optical fiber communication network and rescue return safety instructions in the fire rescue site environment, providing an effective means for the last mile of the fire rescue site.
