Abstract
The utility model discloses a wall structure for cross-under of a power cable, which comprises a cable passage (1) and a wall (3). A cover board (2) is arranged above the cable passage (1); a sealed space is surrounded by the cable passage (1), the cover board (2) and the wall (3); the wall (3) is provided with a threading hole; the threading hole is filled with a fire retardant (4). Due to adoption of the structure, fire can be effectively prevented from entering another room from one room to avoid increase of loss.
Description
Technical field
The utility model relates to power equipment Infrastructure field, specifically for the wall body structure of cross-under power cable.
Background technique
Power cable is mainly used in controlling installation, connection device, transmits electric power etc., is a kind of thing common and indispensable in daily life.
At present, in order to realize the cable in Liang Ge room, connect, normally boring on the wall, then passes through hole, cable Cong Yige guides to another room in room, in this case with regard to there being a problem, when breaking out of fire, because cable surface is flammable material, therefore, the intensity of a fire probably enters another room by threading hole Cong Yige room, causes the intensity of a fire constantly to expand, and brings serious loss.
Model utility content
The utility model provides the wall body structure for cross-under power cable, has solved cable cross-under mode in the past, easily causes the in the situation that of fire, and the intensity of a fire constantly expands, and brings the problem of heavy losses.
The utility model is that technical solution problem is achieved through the following technical solutions: for the wall body structure of cross-under power cable, comprise cable passage and body of wall, the top of described cable passage is provided with cover plate, cable passage, cover plate and body of wall surround a seal space, described body of wall is provided with threading hole, in described threading hole, is filled with fire retardant.The seal space that cable passage, cover plate and body of wall surround can effectively reduce the oxygen concentration in this space, makes the flammable condition of not reaching of cable insulation; Filler and fire-retardant in threading hole, can effectively prevent that the intensity of a fire Cong Yige room from entering another room simultaneously.
Further, described cover plate is provided with handle.
Further, the length of described cover plate be equal to or greater than cable passage length 1/2.
Further, described fire retardant adopts PVC fire retardant.The features such as it is few that PVC fire retardant has adding quantity, and flame retarding efficiency is high, low-smoke low-toxicity.
Further, the height of described threading hole be equal to or less than cable passage height 1/3.
The utility model compared with prior art has the following advantages and beneficial effect: the utility model adopts cable passage, cover plate and body of wall to surround seal space, effectively reduce the oxygen concentration in this space, make the flammable condition of not reaching of cable insulation, while filler and fire-retardant in threading hole, can effectively prevent that the intensity of a fire Cong Yige room from entering another room, avoid increasing the weight of of loss.
