Description

Fire-proof sleeve for electric pole

Technical Field

The utility model relates to an electric power unit field, in particular to pole fire prevention cover.

Background

In an electric power distribution grid, a pole is a very common, and is a facility for carrying grid wires. The existing electric poles are generally made of wood, cement materials, steel pipes or glass fiber reinforced plastic composite materials. The fire behavior of wooden pole and combined material pole is often relatively poor, then is burnt out easily when the forest zone takes place the conflagration to influence power transmission and cause loss of property. Consequently, install the fire prevention cover of pole on wooden pole and the combined material pole that is in the forest zone can improve the fire behavior of pole.

SUMMERY OF THE UTILITY MODEL

According to one aspect of the utility model, the utility model provides a fire-proof cover for the electric pole, which comprises two fire-proof layers with semicircular sections, wherein the fire-proof layers are sleeved outside the electric pole, two ends of each fire-proof layer are provided with connectors, and the fire-proof layers are connected with each other through the connectors; the fireproof layer comprises a fireproof layer body, a fireproof layer and a fireproof layer, wherein the fireproof layer body is provided with an inner layer and an outer layer, the inner layer and the outer layer of the fireproof layer body are supporting protective layers, and ceramic fiber materials are filled between the supporting protective layers.

The utility model provides a pole fire prevention cover can effectively carry out fire protection to wooden pole and combined material, installs it on being in the pole in regions such as forest and easy conflagration breaing out, enables the pole not receive the damage when the conflagration breaing out.

In some embodiments, a fire-retardant fiberglass cloth is affixed between the ceramic fiber material and each of the support and protective layers. Wherein, fire-retardant glass fiber cloth can more effectual improvement flame retardant coating's fire prevention fire-retardant effect.

In some embodiments, a fire retardant coating is applied between the ceramic fiber material and each of the supporting protective layers. This is the third scheme of flame retardant coating, and fire retardant coating can effectively improve the fire prevention fire behaviour of pole fire-proof cover equally.

In some embodiments, the pole is made of wood or glass reinforced plastic composite. From this, limited the pole kind of pole fire prevention cover adaptation and be applicable to the area of easily taking place the fire in the forest.

In some embodiments, the support and protection layer is made of a metal material that is resistant to high temperatures and has high strength. Therefore, the material selection of the supporting protective layer needs to be capable of supporting the fireproof sleeve and playing a role in resisting external force.

In some embodiments, the coupling is made of a metallic material that is resistant to high temperatures and has high toughness. The material selection of the coupling piece therefore requires a reliable connection of the two fire protection layers.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 schematically shows a structure of a pole fire-proof sheath according to an embodiment of the present invention, and fig. 2 shows a layered structure of an embodiment of the fire-proof layer of fig. 1. As shown in fig. 1-2, the fireproof sleeve is used for being sleeved on the outside of the electric pole 1 to protect the electric pole 1, and is generally used for the electric pole 1 made of wood or glass fiber reinforced plastic composite materials, and is particularly suitable for being installed on the electric pole 1 in areas where fire easily occurs, such as forests and the like.

This fire prevention cover surrounds by the flame retardant coating 2 of two separations and constitutes, wherein, two flame retardant coating 2's structure is the same, and its cross-section is semi-circular to every flame retardant coating 2's both ends all are provided with connector 3, and each flame retardant coating 2's both ends then respectively through each connector 3 interconnect, constitute a drum jointly, and establish pole 1 cover and protect in the drum.

The fireproof layer 2 is formed by mutually overlapping and combining a plurality of layers of different materials, the inner layer and the outer layer are both supporting and protecting layers 4, and the supporting and protecting layers 4 are made of high-temperature-resistant and high-strength metal materials. And ceramic fiber materials 5 are filled between the supporting and protecting layers 4. The ceramic fiber material 5 has the advantages of light weight, high temperature resistance, low heat conductivity and the like, is a good flame-retardant heat-insulating material, and can effectively improve the fireproof effect of the fireproof layer 2.

Preferably, the coupling 3 is generally made of a high temperature resistant and high toughness metal. Has certain fireproof effect.

Fig. 3 shows a layered structure of a second embodiment of the flame retardant layer 2 in fig. 1. As shown in fig. 3, on the basis of the first embodiment, the flame-retardant glass fiber cloth 6 may be filled between the ceramic fiber material 5 and each support protection layer 4, and the flame-retardant glass fiber cloth 6 has excellent heat resistance, insulation property and tensile strength, so that not only the fireproof effect of the fireproof layer 2 can be effectively improved, but also the effects of electric leakage prevention, corrosion resistance, impact resistance and the like can be achieved, and the protection effect on the electric pole 1 is further improved.

Fig. 4 shows a layered structure of another embodiment of the flame retardant layer 2 in fig. 1. As shown in fig. 4, in addition to the first embodiment, a fireproof coating 7 may be further coated between the ceramic fiber material 5 and each support and protection layer 4, so as to further improve the fireproof effect of the fireproof layer 2.
