Abstract
The utility model relates to a cable trench ventilation device comprising a ventilation well and an air flue communicated with one side of a cable trench, wherein the bottom of the ventilation well is communicated with the air flue, a well mouth of the ventilation well is provided with a ventilation room, and four sides of the ventilation room is provided with shutters. The ventilation well and the air flue are communicated with the cable trench, due to thermal convection of gas inside and outside of the cable trench, the temperature in the cable trench is lowered, and the heat dissipation problem of cables is effectively solved. Meanwhile, air convection is formed outside and inside of the cable trench so that content of harmful gas inside the cable trench is reduced and life security of maintenance staff is guaranteed.
Description
Technical field
The utility model relates to a kind of tunnel ventilation field, is specifically related to a kind of cable trench ventilation installation.
Background technology
Fast development along with the urban modernization construction, a new step has been stepped in power construction, a large amount of cable conduit net layings is located at the end, ground, along with the increase of the increasing of cabling radical in pipe network, cable transfer load capacity, the electric cable heating amount increases, and cable pipe network inside does not have the device of heat dissipation ventilation, particularly under the extreme temperature in summer, be subject to the large double influence of environment temperature and power load, often easily cause the power cable overload to burn out, also might cause fire what is more.In the cable pipe network, atmosphere draught-free is caused in airtight space simultaneously, and pernicious gas is accumulated in the cable pipe network for a long time, badly influences the attendant's life and health that enters into internal overhaul.
Summary of the invention
In view of this, the purpose of this utility model is and a kind of cable trench ventilation installation, solved the problem of cable trench inner ventilation heat radiation, guaranteed the normal operation and maintenance personnel's of electric power facility safety.
The utility model discloses a kind of cable trench ventilation installation, comprise ventilating shaft and the air channel that is communicated with cable trench one side, described ventilating shaft bottom is communicated with the air channel, and the well head of described ventilating shaft is provided with ventilating house.
Further, described ventilating house is provided with shutter on four sides.
Further, described shutter is aluminium alloy window.
Further, be provided with the gutter bottom described air channel and cable trench one side connectivity part.
The beneficial effects of the utility model are: the utility model cable trench ventilation installation, be communicated with cable trench by ventilating shaft and air channel, and by the thermal convection current of gas inside and outside cable trench, reduce the temperature in cable trench, effectively solved the problem of cable heat radiation; Simultaneously cable trench is outside has formed cross-ventilation with cable trench inside, has reduced the content of the inner pernicious gas of cable trench, has guaranteed attendant's life security.
Description of drawings
For the purpose, technical scheme and the advantage that make utility model is clearer, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Fig. 1 is structural representation of the present utility model, and as shown in the figure, a kind of cable trench ventilation installation comprises ventilating shaft 1 and the air channel 2 that is communicated with cable trench 3 one sides, and described ventilating shaft 1 bottom is communicated with air channel 2, and the well head 1a of described ventilating shaft 1 is provided with ventilating house 4.After the inside and outside connection of cable trench 3, air forms convection current, and the heat that cable produces is discharged, and pernicious gas content is reduced.
In the present embodiment, described ventilating house 4 four sides are provided with shutter 5, can prevent that rainwater from entering into cable trench 3 inside.
In the present embodiment, described shutter 5 is aluminium alloy window.
In the present embodiment, described air channel 2 is provided with gutter 6 bottom cable trench 3 one side connectivity parts, when having water to enter into cable trench 3 from ventilating shaft 1, guaranteed the smooth discharge of ponding, avoids the immersion corrosion to cable.
The utility model cable trench ventilation installation on the basis of common power cable ditch, arranges a cable trench ventilation installation every about 50m, and in its relative cable trench position, the movable cable trench cover is set, and the personnel of maintaining easily enter maintenance.By the thermal convection current inside and outside cable trench, reduce the temperature in cable trench, effectively solved the problem of cable trench ventilation and heat.Can afforest processing around the cable trench ventilation installation, coordinate mutually with landscape planning on every side, reach landscaping effect.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present utility model that appended claims limits.
