Description
Technical field
The utility model is related to aproll cables on cable duct of substation dehumidifying application field more particularly to a kind of ventilation rainproof
Trench cover.
Background technology
In substation, cable duct is a roof leaking, humidity, ponding, extends in all direction and closed place, be substation most
Moist place, and be exactly that this place is secondary with terminal box, mechanism case, convergence control cabinet, the intelligent terminal cabinet of electrical equipment etc.
Directly communicated in equipment box, the cable and optical cable of a large amount of various various outer diameters enter from cable duct in equipment box, in cable and
Optical cable enters from cable duct in the installation process in equipment box, since cable is circular, there are gap between cable and cable,
Existing mounting process does not solve the problems, such as this effectively, and equipment closure does not block the gap between cable and cable yet, finally,
Equipment box is communicated by a large amount of cables with the gap between cable with cable duct, a large amount of moisture is caused in cable duct to pour in secondary
In equipment box, apparatus insulated situations such as reducing short circuit, corrosion open circuit is caused to happen occasionally, seriously affects the peace of equipment
Full stable operation.
Current cable duct is both provided with fire prevention divider wall every 10 meters to 15 meters, and air containment is in certain region in ditch
It is interior to circulate, and the entity structure that more cable channel cover plate is concreting is used at present, nothing is appointed on cable channel cover plate
What divulge information dehumidifying channel or hole, therefore moisture can only be entered by gap existing between cable convergence control cabinet, mechanism case,
In the equipment such as terminal box, cause secondary device failure, it is therefore desirable to propose a kind of rain-proof cable duct with secondary ventilation device
Cover board can effectively discharge the moisture in cable duct.
Utility model content
The technical issues of solution of the utility model：A kind of rain-proof cable channel cover plate with secondary ventilation device is provided,
To solve traditional cement cable channel cover plate without it is any ventilation dehumidifying channel or device, cable duct moisture can not discharge and into
Enter the problem of causing equipment fault in the secondary bin of electrical equipment.
The technical solution of the utility model：
A kind of rain-proof cable channel cover plate with secondary ventilation device, it is described including cable channel cover plate and ventilation hole
Symmetrical round hole, axial flow blower are separately positioned in two round holes there are two settings in the middle part of cable channel cover plate, cable operculum colpi
At least two strips ventilation hole is additionally provided on plate, the rain-proof overhead guard is fixed above cable channel cover plate, prevents
Rain overhead guard side wall is provided with ventilation opening.
The rain-proof overhead guard top surface is ramped shaped, and inclined face of keeping off the rain, the gear are provided on the ventilation opening
Rain face is connect with rain-proof overhead guard top surface.
Anti- toy net is provided on the ventilation opening, the anti-toy net is made of stainless steel material.
Dash side is provided on the inside of the anti-toy net.
The beneficial effects of the utility model：A kind of rain-proof cable channel cover plate with secondary ventilation device is provided, by
Setting ventilation hole and axial flow blower, can effectively exclude the moisture inside cable duct by force on cable channel cover plate, it is ensured that electricity
Moisture in cable ditch will not be entered in the secondary devices babinet such as convergence control cabinet, meanwhile, cable channel cover plate top is provided with rain-proof
Overhead guard and dash side, it is ensured that outside moisture will not be entered in cable duct, furthermore, it is additionally provided on rain-proof overhead guard ventilation opening
Anti- toy net effectively prevents toy to enter cable duct by cable channel cover plate ventilation hole to cause equipment event
Barrier, the utility model have good economy and practicability.
Description of the drawings
Fig. 1 is the utility model appearance diagram；
Fig. 2 is the utility model front view；
Fig. 3 positions the utility model side view；
It is identified in figure：1st, cable channel cover plate, 2, ventilation hole, 3, rain-proof overhead guard, 4, axial flow blower, 5, anti-toy net,

Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of rain-proof cable channel cover plate with secondary ventilation device as shown in Figure 1, including cable channel cover plate 1, axis stream
Wind turbine 4, rain-proof overhead guard 3, dash side 6 and anti-toy net 5, there are two symmetrical circles for the 1 middle part setting of cable channel cover plate
Shape hole, 4 diameter of aperture ratio axial flow blower of round hole is bigger, and an axial flow blower 4, cable are respectively arranged in two round holes
Also being arranged side by side on trench cover 1 has several strip ventilation holes 2, and for the moisture in cable duct to be discharged, described is anti-
Rain overhead guard 3 is fixed at 1 top of cable channel cover plate by fixing bolt, and uses the sealing materials such as fluid sealant sealing rain-proof top
Cover 3 and 1 junction of cable channel cover plate, the ventilation hole 2 that the rain-proof overhead guard 3 can be all on covering cable trench cover 1, simultaneously
3 side wall of rain-proof overhead guard is provided with the ventilation opening 7 of rectangle, and anti-toy net 5, the anti-toy net 5 are provided on ventilation opening 7
