Description
Technical field
The utility model relates to ventilation field, particularly, relates to a kind of ventilation installation for cable trench.
Background technology
Cable trench of the prior art is arranged at below ground usually, for sealing designs, does not have ventilation installation, entering cable trench and damaging electric power facility, not having obvious gap between cover plate to prevent toy.Therefore, cable trench air permeability is poor, does not exchange by inner air and outer air and is evaporated away by moisture.This just easily makes the cable bearer in cable trench corrode, and body of wall flakes, loose, cover plate damage etc., thus causes electric power facility needs in cable trench often to keep in repair or replacing, and maintenance cost is higher.
Therefore, need to provide a kind of ventilation installation for cable trench, to make cable, there is good running environment.
Utility model content
The purpose of this utility model is to provide a kind of ventilation installation for cable trench and has good running environment to make cable.
To achieve these goals, the utility model provides a kind of ventilation installation for cable trench, wherein, this ventilation installation comprises the roof being arranged at the bed plate around cable trench ventilation opening, the surrounding wall supported by this bed plate and covering described surrounding wall top regularly, and wherein said surrounding wall is provided with multiple gravity vent.
Preferably, described cable trench ventilation opening falls in the scope of described roof projection on the ground.
Preferably, described roof is set to herringbone structure.
Preferably, described surrounding wall has head and the tail continuously and form four of cuboid structure and face the wall and meditate.
Preferably, described four face the wall and meditate at least one face the wall and meditate on be provided with openable door.
Preferably, the top edge of described bed plate is higher than the described cable trench ventilation opening edge crossing with ground.
Preferably, the gravity vent on described surrounding wall is formed as net structure.
Pass through technique scheme; in order to ventilate to cable trench; the partial cover plate of cable trench can be removed; thus form cable trench ventilation opening; this ventilation installation is arranged at this cable trench ventilation opening place, multiple gravity vents that surrounding wall is arranged can allow the air inside and outside cable trench to exchange, thus are discharged by the moisture laden air in cable trench; protect the electric power facility in cable trench, make cable have good running environment.
Other features and advantages of the utility model are described in detail in detailed description of the invention part subsequently.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
The utility model provides a kind of ventilation installation for cable trench, wherein, this ventilation installation comprises the roof 3 being arranged at the bed plate 2 around cable trench ventilation opening, the surrounding wall 1 supported by this bed plate 2 and covering described surrounding wall 1 top regularly, and wherein said surrounding wall 1 is provided with multiple gravity vent.
Pass through technique scheme; in order to ventilate to cable trench; the partial cover plate of cable trench can be removed; thus form cable trench ventilation opening; this ventilation installation is arranged at this cable trench ventilation opening place, multiple gravity vents that surrounding wall 1 is arranged can allow the air inside and outside cable trench to exchange, thus are discharged by the moisture laden air in cable trench; protect the electric power facility in cable trench, make cable have good running environment.
Particularly, this ventilation installation preferred embodiment, as depicted in figs. 1 and 2, is arranged at cable trench ventilation opening place by the one that the utility model provides, moisture laden air in cable trench by the gravity vent of setting on surrounding wall 1 outwardly, thus can make to keep dry in cable trench environment.In addition, the roof 3 being arranged at surrounding wall 1 top can prevent rainwater from entering into cable trench, thus contributes to keeping dry in cable trench environment.
In order to prevent rainwater from falling in cable trench better, a kind of preferred embodiment that the utility model provides, as depicted in figs. 1 and 2, described cable trench ventilation opening falls in the scope of described roof 3 projection on the ground.Compared with the area of cable trench ventilation opening, roof 3 can be set to have larger projected area in the horizontal plane, therefore, when rain and be attended by blow, can prevent rainwater from dropping in cable trench better.
In order to prevent that roof 3 forms ponding, improve the application life of ventilation installation, a kind of detailed description of the invention that the utility model provides, as depicted in figs. 1 and 2, described roof 3 is set to herringbone structure, flows down fast from roof 3 to make rainwater.On the other hand, excessive accumulated snow on roof 3 can be prevented equally, to improve the application life of this ventilation installation at the weather that snows.
In order to make this ventilation installation more tight, prevent toy from entering in cable trench, as a kind of concrete embodiment, as depicted in figs. 1 and 2, described surrounding wall 1 has head and the tail continuously and form four of cuboid structure and face the wall and meditate.Surrounding wall 1 head and the tail connect in turn, can prevent toy from entering in cable trench from the gap between adjacent two surrounding walls 1 and damage electric power facility.
Conveniently operative employee enters into carry out repair and maintenance to electric power facility in cable trench, according to a kind of preferred embodiment that the utility model provides, as depicted in figs. 1 and 2, described four face the wall and meditate at least one face the wall and meditate on be provided with openable door.
In order to prevent excess surface water from flowing in cable trench, a kind of detailed description of the invention that the utility model provides, as depicted in figs. 1 and 2, the top edge of described bed plate 2 is higher than the described cable trench ventilation opening edge crossing with ground.This bed plate 2 can be set to be fixed on hermetically around cable trench ventilation opening, and when running into rainy weather, the ponding on road surface also can not be flow in cable trench by cable trench ventilation opening, thus maintains the running environment of the drying in cable trench further.
As one preferred embodiment, as depicted in figs. 1 and 2, the gravity vent on described surrounding wall 1 is formed as net structure.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
