Description
Technical field
The invention belongs to electrical facility technical field, especially a kind of fire proof power cable ditch.
Background technology
The mode of cable laying is transitioned into underground laying from aerial suspension, excellent with construction safety, easy care etc.
Point, wherein generally using concrete or brickwork construction, top to be covered with cover board for providing the cable duct in laying space.Cover board
Face can be flushed with ground, convenient for open, also some be slightly less than ground and paint one layer of cement on the cover board, with prevent cover board with
Ground is uneven enters cable duct with rainwater.
Since cable duct is laid on substation, when the transformer equipment in substation breaks down, such as short circuit, electricity can be caused
Electric cable heating in cable ditch catches fire, and leads to the power failure of bigger(Transformer tripping etc.), and cable outer wall is plastic cement material,
Flame retardant property is relatively low, especially multi-layer cable or the mode of cross cable laying, will form stereo burning, the intensity of a fire is difficult to control
System, caused by lose and can not estimate, so electric power enterprise needs design fire proof construction, such as Granted publication when making cable duct
The patent document of number CN207490477U discloses a kind of auxiliary ditch of novel ventilated fireproof cable, including axial flow blower, air duct and at least
Two sides fire damping wall, the setting of ventilating fire prevention cable auxiliary ditch the auxiliary ditch air inlet of ventilating fire prevention cable and go out in cable tap drain side
Air port is connected to the cable tap drain of fire wall both sides respectively, and fire damping wall is arranged on the auxiliary ditch side wall of ventilating fire prevention cable, declines
Subtract and obstruct the intensity of a fire, prevents fire spread, but when a fire, the intensity of a fire is easier to become larger under the drive of wind turbine.
Authorization Notice No. CN206559014U discloses a kind of fire prevention water-retaining structure of cable duct, including fire prevention is husky and twice are kept off
Waterwall, twice waterwall are built a wall in cable duct, and the height of the waterwall is flushed with the height of the cable duct, the twice
Waterwall build a wall between be separated with a distance;Cable aperture is provided on the waterwall, cable is passed through by the cable aperture
The waterwall is enclosed with fire prevention packet around the cable between the twice waterwall;Landfill is full among the twice waterwall
The fire prevention is husky, and the husky landfill residence of fire prevention is stated the cable between twice waterwall and wrapped with fire prevention.The structure is husky using fire prevention
The intensity of a fire is stopped, but cannot achieve fire extinguishing, so not solving the problems, such as cable duct fire fundamentally.
Invention content
In view of this, in view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of fire proof power cable ditch, this hair
The bright structure by channel body is improved, and the accommodating chamber of fire proofing material is filled in side shield and cover board, is being waited for
Self-extinguishing while rescue avoids the secondary failure of power equipment.
In order to achieve the above objectives, the present invention uses following technical scheme:
A kind of fire proof power cable ditch, including multiple channel bodies, the channel body include bottom plate, side shield and cover board, institute

Close-fitting second auxiliary section in auxiliary section, between the bottom plate and side shield, between the first auxiliary section and the second auxiliary section
Containment member is set.
Further, first auxiliary section and the second auxiliary section are the L-shaped groove mutually fastened, and the containment member is rubber
Adhesive tape is mounted on the first auxiliary section or the second auxiliary section.
Further, first auxiliary section is U-lag, and the second auxiliary section is and mating prefabricated rectangular of U-lag
Component, the containment member are rubber strip, are mounted in the first auxiliary section.
Further, the cover board upper surface is upward arcuate structure, and radian is 3-5 °.
Further, multiple discharge ports of side shield are obliquely installed towards the direction of holder, multiple discharge ports of cover board
It is divided into the direction that two groups are respectively facing holder to be obliquely installed.
The beneficial effects of the invention are as follows:
1. the present invention is improved by the structure to channel body, it is arranged on side shield and cover board and is filled with fire proofing material
Accommodating chamber, when fire occurs in cable duct, high temperature makes plugging mechanism rupture, fire proofing material, such as sandy soil, falls into cable duct
Put out a fire, realize effect of the cable duct from fire extinguishing, compared with the prior art in add the precautionary approach of fire wall, the present invention is waiting
Self-extinguishing while to be rescued avoids the secondary failure of power equipment;It is noted that plugging mechanism includes plastic film
And the primary mineral of vermiculite powder being arranged between plastic film and fire proofing material, plastic film voluntarily melt, primary mineral of vermiculite powder of arranging in pairs or groups
Self-expanding under high temperature environment, makes that plastic film ruptures or plugging mechanism includes bladder member and filling out under double mechanism effect
Fill the hydrogen in bladder member, bladder member is that plastic film voluntarily melts, in hydrogen can also occur at high temperature it is quick-fried
It is fried that bladder member is made to rupture.
2. channel body by being designed to prefabricated multi-hull type structure by the present invention, single bottom plate, side shield, cover board can
To be produced in advance in processing factory, artificial, the cost input for avoiding site operation from bringing, and by inserting between each single structure
The mode connect carries out Assembling, has the characteristics that construction efficiency is high, quality controllable;
Applicant studies for a long period of time discovery, and using the modular channel body of precast construction, the gap position of assembling can seep water
Phenomenon, the infiltration at earth's surface side shield below will have a direct impact on the service life of holder, and the present invention is directed to should
Problem is prevented using kinds of schemes:First, the inserting mode between side dams and bottom plate can avoid bottom infiltration;Separately
Outside, pre- antiseepage is carried out by the tight fit and use containment member of the first auxiliary section and the second auxiliary section between adjacent side shield
Water;In addition, lower face setting and the matched strip of the second card slot between cover board and side shield.Various structures, which cooperate, to be realized
The sealing of channel body, the problem of not only solving infiltration, and the oxygen content in cable duct is made to reduce, contribute to control fire
Gesture.
3. structure design cover board upper surface is upward arcuate structure, radian is 3-5 °, this structure design will be covered
Enlarged in thickness among plate enhances the compressive property of cover board, passes through convenient for cable duct upper vehicle.
4. bottom plate upper surface is the arc or triangular structure to lower recess, osculum, row is arranged in the recess of bottom plate
Water hole is funnel-shaped structure, and after infiltration inside seal failure occurs for cable duct, water drains into ground out of osculum in the middle part of bottom plate
Under, prevent ditch internal water accumulation the problem of.
