  9. A cover portion formed in the shape of a tube that can be expanded or compressed in the longitudinal direction and formed to accommodate a wire inside; A head portion provided at the end of the above-mentioned cover portion; and It includes an air valve disposed in the head portion and connected to an air pocket formed in the cover portion, and controlling the inflow and outflow of air into the air pocket; The above cover part is, An expandable wire protection tube with a cover slit formed along the longitudinal direction and one side open.
  10. A cover portion formed in the shape of a tube that can be expanded or compressed in the longitudinal direction and formed to accommodate a wire inside; A head portion provided at the end of the above-mentioned cover portion; and It includes an air valve disposed in the head portion and connected to an air pocket formed in the cover portion, and controlling the inflow and outflow of air into the air pocket; The above head part is, An expandable wire protection tube with a head slit formed along the longitudinal direction and one side open.
  11. An inflatable wire protection tube according to any one of Clauses 1, 7, 9 and 10; and An air gun connected to one end of the air valve and supplying air to the air pocket or sucking in air present in the air pocket; An inflatable wire protection tube unit including

Description

Expandable wire protection tube and its units The present invention relates to an inflatable wire protection tube and a unit thereof, and more specifically, to an inflatable wire protection tube and a unit thereof that can eliminate the inconvenience of installing multiple protection tubes by installing a wire protection tube made of a material that can be compressed or expanded in the longitudinal direction. Generally, because high-voltage power lines supplying electricity to buildings are placed close to various structures, electric shock accidents frequently occur when workers come into close contact with or come into contact with these lines during work in close proximity to them. Furthermore, contact between electrical installations and foreign objects caused by rain, wind, and currents can lead to power outages. To prevent such electric shock and power outage accidents, insulating protective conduits for straight lines are manufactured to protect the straight sections of high-voltage power lines at construction sites and other locations, thereby contributing to ensuring the safety of workers during work in close proximity to power lines. FIG. 1 illustrates a conventional wire protection tube installed on a wire, and FIG. 2 illustrates a conventional wire protection tube. Referring to FIG. 1 and FIG. 2, the conventional wire protection tube (20) is manufactured as a single item with lengths of 2m and 1m. The wire protection tube (20) is composed of a head part (21) and a cover part (22), and the head part (21) is fastened to interlock with the end of the cover part (22) of another wire protection tube (20), so that the wire protection tubes (20) can be installed by connecting them to each other as shown in FIG. 1. However, the wire protection tube (20) was manufactured as a single item with a length of 2m and 1m, so it was cumbersome to install multiple units in the same location to cover the entire span of the wire (10). There was a problem in that the time required to install the wire protection tubes (20) was long, and as time passed, gaps formed between the wire protection tubes, causing the wire protection tubes (20) to separate from each other. In addition, when removing the wire protection tubes (20), a large number of wire protection tubes (20) had to be removed, resulting in excessive work time and reduced work efficiency. Figure 1 is a drawing showing the appearance of a conventional wire protection pipe installed. Figure 2 illustrates a conventional wire protection tube. FIG. 3 illustrates a side view of an expanded state of an expandable wire protection tube as an embodiment of the present invention. FIG. 4 illustrates a side view of an inflatable wire protection tube in a compressed state as an embodiment of the present invention. FIG. 5 is a cross-sectional view showing an air pocket and an air valve of an inflatable wire protection tube as an embodiment of the present invention. FIG. 6 illustrates a rear view of an expandable wire protection tube as an embodiment of the present invention. FIG. 7 illustrates the operation of an air valve of an inflatable wire protection tube as an embodiment of the present invention. FIG. 8 illustrates a side view of an expandable wire protection tube unit as an embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments below.
