Description
Technical field
The present invention relates to power construction security technology area, is a kind of cable trough fire compartment wall specifically.
Background technology
At present, the cable trough of a lot of transformer station, mostly adopt the traditional firewall that grey brick and sandstone make, the simple fire compartment wall that minority transformer station adopts PLASTIC LAMINATED, fire prevention bag, toughened glass to make, along with electric power system is growing, equipment is constantly updated, and more and more higher to the requirement of cable duct of substation fire compartment wall, existing power cable ditch fire compartment wall exists following shortcoming:
1, pre-testing cable hole for subsequent use is not had.When replacing cable or when setting up cable, original fire compartment wall must be removed, when removing fire compartment wall, cable solidify by cement mortar, if careless manipulation will cause cable fault, and owing to being that grey brick and sandstone are made, the long-term stream of coarse sand collapse make cable trough and cable unclean.
2, existing cable ditch fire compartment wall drainage channel lacks anti-blocking toy measure, and toy enters and power cable can be caused damaged, causes electrical network hidden danger.
When 3, raining, due to impeded drainage, sludge water enters cable trough, causes cable is wrapped up by mud for a long time unclean, makes troubles to maintenance, and increases maintenance cost.
4, existing cable ditch fire compartment wall cover plate uses common toughened glass, not anti-skidding, do not prevent fires, not load-bearing, particularly when snowing icing, often occurring that tour personnel fall down, tumble injury phenomenon, causing serious potential safety hazard to electrical production.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of cable trough fire compartment wall, sets up cable during to realize scrap build in the future, and the object preventing toy from invading.
For achieving the above object, the present invention includes upper cover plate, left and right wall, lower floor, forward and backward wall, cable bearer, cable, cable bearer is fixed on left and right wall, cable on cable bearer is through forward and backward wall, described forward and backward wall leaves cable hole for subsequent use, lower floor has aperture.
Described left and right wall, lower floor, forward and backward wall are PLASTIC LAMINATED.
Described upper cover plate comprises anti slip glass plate, fire blanket, flame resistant glass plate, and described fire blanket is between anti slip glass plate and flame resistant glass plate, and anti slip glass plate is placed in skin, and flame resistant glass plate is placed in internal layer; Described fire blanket is " mouth " font structure of hollow, and surrounding contacts with anti slip glass plate and flame resistant glass plate, is provided with the sign of " fire compartment wall " printed words in the middle of " mouth " font.
Described cable bearer is glass fibre reinforced plastic support.
Described lower floor bottom is provided with drainage channel, and drainage channel communicates with lower floor through aperture, and the described drainage channel degree of depth is 3-5cm; Drainage channel place is provided with mudhole, and mudhole is positioned at the below of lower floor.
Described mudhole is equipped with the grid of prevention toy.
Heat insulation, moistureproof fire prevention bag is provided with in the fire compartment wall that described upper cover plate, left and right wall, lower floor, forward and backward wall surround.
Described cable punching hole place is surrounded by back-fire relief band, and cable and forward and backward wall contact position are fixed with fire-proof mud, fluid sealant.
Described cable vacancy for subsequent use is fixed by fire-proof mud, fluid sealant.
Compared with prior art, the present invention changes the drawback that traditional firewall " disposable " makes, and can repeatedly use, and its cable in stock hole, can open hole when needed, waits after construction again by holes blocking; By using the cable section of back-fire relief band parcel perforation place, not only can not damage cable, can also fire protecting performance be improved; Cable bearer changes the bad and extremely corrosion-prone shortcoming of traditional cable bearer fire protecting performance made of iron; Cable drainage channel, under can preventing abnormal condition, cable trough enters water problem; Netted osculum can play the effect preventing toy from invading; Upper cover plate can prevent from slipping during the daily tour of operative employee, and increases the heavy burden of cover plate, improves fire compartment wall useful life.Structure of the present invention is simple, easy to make, uses, increase work efficiency when being convenient to post facility transformation cable laying.
