Detailed Description

In order to make the technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The utility model provides a high-strength flame-retardant control cable for a coal mine, which is shown in figures 1 to 3 and comprises a cable conductor 1, wherein an insulating layer 2, a heat-insulating layer 3 and a metal armor layer 4 are sequentially arranged outside the cable conductor 1, a first outer protective sheath layer 5 and a second outer protective sheath layer 6 which are assembled and connected are arranged outside the metal armor layer 4, the cable conductor 1 is outwards connected with a heat transfer component 8, the heat transfer component 8 penetrates through the insulating layer 2 and the heat-insulating layer 3, the heat transfer component 8 is made of a material with a better heat transfer coefficient, heat dissipation holes 9 are respectively arranged outside the metal armor layer 4 and the second outer protective sheath layer 6, the heat dissipation holes 9 are distributed at equal intervals, heat is transferred to the heat dissipation component 8 from the cable conductor 1, and the heat dissipation component 8 transfers the heat to the outside to realize the function of heat emission; the bottom end of the second outer protective sheath layer 6 is provided with a support leg 10, so that the control cable can be fixedly placed on the ground, and in order to ensure the stability of the control cable, the support leg 10 can be provided with a positioning hole and fixed by a bolt; the connection part of the first outer protective sleeve layer 5 and the second outer protective sleeve layer 6 is provided with a downward inclined plate 7, the inclined plate 7 is arranged above the heat dissipation holes 9, and rainwater can be prevented from flowing back through the heat dissipation holes 9 in rainy days; be equipped with slider 11 and spout 12 between the hang plate 7 to be equipped with fixture block 13 and draw-in groove 14 respectively in the both sides of slider 11 and spout 12, the preferred fixture block 13 of this embodiment and draw-in groove 14 are globular protrusion and globular recess, when first outer protective sheath layer 5 and the outer protective sheath layer 6 of second were installed, the mutual joint between accessible fixture block 13 and the draw-in groove 14 realized fixing between the two.
