Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.
[0025] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the utility model.
[0026] EMBODIMENT
[0027] The following will be further described in combination with specific embodiments, referring to Figures 1-6 The utility model is a kind of fireproof heat insulation protection device for building electromechanical pipeline, referring to Figure 1 And Figure 2, including cable core 1, the peripheral side of cable core 1 is fixedly installed heat pipe 2, heat pipe 2 is distributed spirally around the center of cable core 1. The first surface of heat pipe 2 faces the surface of cable core 1, and the first surface of heat pipe 2 is fixedly installed with first metal strip 21, first metal strip 21 abuts against the surface of cable core 1, and first metal strip 21 is made of copper or aluminum or other metal with high heat dissipation capacity. The inside of heat pipe 2 is closed and arranged with heat-conducting liquid, and the heat-conducting liquid in heat pipe 2 is arranged in a non-full pipe. The heat-conducting liquid has a high thermal conductivity, and the boiling point of the heat-conducting liquid is lower than the surface temperature of cable core 1 during normal operation. When the cable is in normal operation, the heat-conducting liquid absorbs the heat of cable core 1, and the heat-conducting liquid vaporizes after absorbing heat and carries away heat, and the heat-conducting liquid after vaporization moves to a place with lower temperature and liquefies to dissipate heat, reducing the temperature of the surface of cable core 1. When the cable is affected by the installation environment and is locally heated, the heat-conducting liquid can quickly absorb the heat of cable core 1.
[0028] Referring to Figure 1 and Figure 2 , the second surface of heat pipe 2 is opposite to the first surface of heat pipe 2, and the second surface of heat pipe 2 is fixedly installed with second metal strip 22, and second metal strip 22 is used to diffuse the heat in heat pipe 2 to the surrounding air.
[0029] Referring to Figure 3 and Figure 4 , the outer side of heat pipe 2 is also fixedly installed with mounting ring 3, and the outer side of mounting ring 3 is provided with a plurality of lifting pieces 31, and the plurality of lifting pieces 31 are uniformly distributed on mounting ring 3. One end of lifting piece 31 is fixedly connected with mounting ring 3, and the other end of lifting piece 31 is a free end. Lifting piece 31 includes two metal sheets, the two metal sheets are riveted to each other, and the thermal expansion coefficient of the metal sheet on the side facing cable core 1 is greater than the expansion coefficient of the metal sheet on the side away from cable core 1. Lifting piece 31 is attached to the surface of second metal strip 22. When the local heat of the cable is too much, the lifting piece 31 at the local position absorbs heat through second metal strip 22, and because the thermal expansion coefficients of the two metal sheets are different, the free end of lifting piece 31 bends away from second metal strip 22.
[0030] Referring to Figure 3 and Figure 4The mounting ring 3 is further provided with a plurality of heat insulation scales 32, which are uniformly distributed on the mounting ring 3 and abut against each other at edges between adjacent heat insulation scales 32 to cover the cable core 1. The heat insulation scales 32 are made of a material capable of resisting fire and heat insulation. The heat insulation scales 32 are in the shape of long strips. The mounting ring 3 is provided with a rotating shaft, one end of the heat insulation scale 32 is rotatably connected to the rotating shaft, and the other end of the heat insulation scale 32 is a free end. The heat insulation scale 32 abuts against the metal sheet on the side of the jacking sheet 31 away from the cable core 1. The rotating shaft is provided with a torsion spring, which is used to drive the heat insulation scale 32 to rotate towards the jacking sheet 31.
[0031] With reference to Figure 5 and Figure 6 The outer side of the mounting ring 3 is fixedly provided with a supporting ring 4, and a gap for rotation of the heat insulation scale 32 is reserved between the supporting ring 4 and the mounting ring 3. The side of the supporting ring 4 facing the mounting ring 3 is provided with a supporting rod 41, and the end of the supporting rod 41 away from the supporting ring 4 is fixedly connected to the outer surface of the mounting ring 3. The supporting rod 41 is used to fix the relative position of the supporting ring 4 and the mounting ring 3. The supporting ring 4 is used to protect the heat insulation scale 32 from being extruded from the outside and unable to rotate normally.
[0032] The working process of the embodiment is as follows: when the local heat generation of the cable increases due to installation environmental factors, the heat of the cable core 1 is transmitted to the heat conducting pipe 2 through the first metal strip 21, the heat conducting liquid in the heat conducting pipe 2 absorbs heat and vaporizes, the vaporized heat conducting liquid moves to a position with lower temperature or liquefies near the second metal strip 22 to dissipate heat, so that the heat is transmitted to the second metal strip 22. The jacking sheet 31 abuts against the second metal strip 22, the jacking sheet 31 absorbs the heat of the second metal strip 22, and the two metal sheets in the jacking sheet 31 expand to different lengths after absorbing heat, so that the free end of the jacking sheet 31 bends away from the cable core 1. The free end of the jacking sheet 31 abuts against the surface of the heat insulation scale 32 and drives the heat insulation scale 32 to rotate around the rotating shaft, so that the heat insulation scales 32 are separated from each other, the contact area between the second metal strip 22 and the air is increased, and the heat of the second metal strip 22 is transmitted to the air to reduce the temperature of the cable core 1.
[0033] When the temperature of the cable after heat transmission is lower than the bending temperature of the jacking sheet 31, the jacking sheet 31 is in a planar shape, and the heat insulation scale 32 rotates towards the cable core 1 under the action of the torsion spring to close the gap between the heat insulation scales 32, so that the heat insulation scale 32 plays a role in fireproofing and heat insulation for the cable core 1.
[0034] The above merely is preferred embodiment of the present utility model, and is not for limiting the present utility model, for the person skilled in the art, the present utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
