Abstract
A self-dehumidifying cable trench comprises a base board on which a side wall is arranged. A cover board is arranged on the side wall. The self-dehumidifying cable trench is characterized in that: the side wall is provided with L-shaped chimneys; a transverse-segment opening of each L-shaped chimney is communicated with an inner space which is surrounded by the side wall and the cover board; a chimney cap is arranged above a vertical-segment opening of the L-shaped chimney; the vertical-segment opening is internally provided with an isolating net; and the L-shaped chimneys on the longitudinal side walls are successively arranged alternatively. Because the L-shaped chimneys are arranged on the side walls, moisture in the self-dehumidifying cable trench can be extracted out on condition of automatic ventilation, thereby saving energy and eliminating a requirement for human operation. After dehumidification, the inner part of the self-dehumidifying cable trench is dry, thereby preventing equipment corrosion, ensuring personal security of operators, reducing operation accidents of an electric network, and facilitating stable operation of the equipment. The self-dehumidifying cable trench is provided with the chimney caps and the isolating nets, and therefore entry of rain water and small animals into the L-shaped chimneys can be effectively prevented, thereby ensuring dryness and cleanness in the self-dehumidifying cable trench.
Description
Technical field
The present invention relates to a kind of cable trough of dehumidifying certainly for cabling.
Background technology
Cable trough is a kind of for cabling, the underdrain that can open.Comprise base plate, on base plate, be provided with side wall body, on side wall body, be provided with cover plate.Described cable and cable terminal case are laid in cable trough.After raining, rainwater enters in cable trough, because cable trough is for a long time in closed state, rainwater is difficult to evaporation, cable trough internal environment humidity, can cause following adverse consequences: 1, under wet environment, cable terminal case inner terminal row modify, cause CT secondary circuit open circuit, threaten operating personnel's life security; 2, ground connection gauze corrosion in ditch, imperfect earth, earth resistance is undesirable, produces counterattack overvoltage, and the counterattack person or electrical secondary system, cause power grid security, interruption of service; 3, cable environment of living in is bad, is unfavorable for the stable operation of equipment.
Summary of the invention
It is inner dry that the technical problem to be solved in the present invention is to provide a kind of guarantee cable trough, ensures operating personnel's life security, reduces power grid security, interruption of service generation, is beneficial to the cable trough of dehumidifying certainly of equipment stable operation.
The present invention is achieved in that
A kind of from dehumidifying cable trough, comprise base plate, on base plate, be provided with side wall body, on side wall body, be provided with cover plate, its special character is, on side wall body, be provided with L-type chimney, the crosspiece opening of described L-type chimney is connected with the inner space that side wall body surrounds with cover plate, above perpendicular section opening, is provided with chimney cowl, in perpendicular section opening, is provided with separation net, describedly be positioned at L-type chimney on longitudinal side wall and arrange along alternatively up and down successively, the difference in height≤20cm between the each chimney of 10cm <.
The material of described L-type chimney is PVC, to ensure its oxidation resistance, toughness, machinability.
The diameter of described L-type chimney is 100mm～110mm, to ensure being issued to optimal ventilation effect in the situation of the intensity that does not affect side wall body.
Described L-type chimney has eight, wherein, uniform three L-type chimneys on each longitudinal side wall body, each cross side body of wall is provided with a L-type chimney, to ensure being issued to optimal ventilation effect in the situation of the intensity that does not affect side wall body.
Described L-type chimney minimum point and ground distance be greater than 20cm, infiltrate to avoid ponding to be connected gap by L-type chimney with side wall body.
The wall thickness of described L-type chimney is 0.8mm～3mm, with proof strength.
The invention has the beneficial effects as follows:
1,, owing to being provided with L-type chimney on sidewall, can be the in the situation that of natural draft this moisture in dehumidifying cable trough be extracted out to energy savings and operating without personnel.
2, after dehumidifying, should be inner dry from the cable trough that dehumidifies, avoid equipment corrosion, ensure operating personnel's life security, reduce power grid security, interruption of service generation, be beneficial to equipment stable operation.
3, be provided with chimney cowl and separation net, can effectively prevent that rainwater and toy from entering L-type chimney, ensured the dry of cable trough inside that certainly dehumidify, clean.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
In figure: base plate 1, side wall body 2, L-type chimney 3, separation net 301, chimney cowl 302, cover plate 4.
Embodiment
As shown in the figure, should comprise base plate 1 from dehumidifying cable trough, on base plate 1, be provided with side wall body 2, on side wall body 2, be provided with cover plate 4.On side wall body 2, be provided with L-type chimney 3, in the present embodiment, described L-type chimney 3 has eight, wherein, uniform three L-type chimneys 3 on each longitudinal side wall body 2, describedly be positioned at L-type chimney on longitudinal side wall and arrange along alternatively up and down successively, difference in height≤20cm between the each chimney of 10cm <, in the present embodiment, taking 15cm as example.Each cross side body of wall 2 is provided with a L-type chimney 3, and L-type chimney 3 minimum points and ground distance are greater than 20cm, in the present embodiment, taking 30cm as example.The material of described L-type chimney 3 is PVC, and diameter is 100mm～110mm, and wall thickness is 0.8mm～3mm.The crosspiece opening of described L-type chimney 3 is connected with the inner space that cover plate 4 surrounds with side wall body 2, above perpendicular section opening, is provided with chimney cowl 202, in perpendicular section opening, is provided with separation net 201.
After rain, when there being wind out-of-date, should under the effect of L-type chimney 3, be drawn out of from the inner moisture of dehumidifying cable trough.
