Description
Technical field
The utility model relates to electric power maintenance field of tool, is specially a kind of cable trench ventilating device.
Background technology
Cable trench is the corridor of substation cable. If cable is likened into blood vessel, so cable trench is exactly the muscle tissue of human body, and cable trench is the important facility of substation. In order to prevent fires, anti-animalcule enter cable trench destroy power cable, the cable trench of substation is generally designed to the closed structure of cement cover board. Owing in the reason cable trenchs such as ventilation condition is poor, load height, temperature is too high, reach 45 DEG C through measurement cable trench medial temperature in summer, greatly reduce the work-ing life of ditch inner cable.
For this reason, Chinese patent CN204497704U discloses a kind of cable trench ventilation casing, comprise the casing being arranged on cable trench, casing is provided with case door, the left wall of described casing, right wall, rear wall is respectively equipped with some ventilation holes, the bottom surface of described casing is provided with some breather holes, described rear wall is provided with ventilation opening, described ventilation opening place is provided with ventilation plant, owing to have employed technique scheme, this practicality is novel, and to have structure simple, practical, the features such as economy, it is to ventilation, the concrete setting of exhaust, greatly reduce the heat dissipation problem in cable trench, but in actual application, the novel radiating effect played in the summer that The sun is shining fiercely of this practicality is limited, need to improve.
Practical novel content
The purpose of this utility model is to provide a kind of cable trench ventilating device, to solve in above-mentioned background technology the problem proposed.
For achieving the above object, the utility model provides following technical scheme:
A kind of cable trench ventilating device, comprises the casing being arranged on cable trench, is provided with some cable beareves in cable trench, and cable is distributed on cable bearer respectively; Casing side is provided with case door, and Zuo Bi, You Bi of described casing is respectively equipped with some ventilation holes, and the bottom surface of described casing is provided with a grille mounting, and on grille mounting, interval is provided with some semi-conductor cooling piece groups;Wherein the cold junction of semi-conductor cooling piece group is down, and hot junction is upward; The roof of described casing is obliquely installed, the top of roof is provided with solar panel, solar panel be arranged on the charging controller inside roof and store battery is connected, described semi-conductor cooling piece group is connected with store battery by controller, the rear wall of casing is provided with ventilation opening, described ventilation opening place is provided with ventilation plant, and the outside of described ventilation opening is provided with the grid that keep off the rain.
As the utility model further technical scheme, described ventilation plant is the exhaust fan being arranged on inside ventilation opening.
As the utility model further technical scheme, described exhaust fan is electrically connected with automatic control device.
As the utility model further technical scheme, described automatic control device is temperature sensor.
As the utility model further technical scheme, described roof near the side of case door lower than another side.
Compared with prior art, the utility model is in use, the semi-conductor cooling piece group arranged bottom casing can generate cold air in cable trench and form cold heat exchange convection current, reduces the temperature in cable trench so that in cable trench, temperature is still in normal level when sweltering heat in summer.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of cable trench ventilating device of the utility model.
In figure: 1-solar panel, 2-charges controller, 3-roof, 4-ventilation opening, and 5-keeps off the rain grid, 6-exhaust fan, 7-casing, 8-grille mounting, 9-cable trench, 10-cable bearer, 11-semi-conductor cooling piece group, 12-case door.
Embodiment
Below in conjunction with embodiment, the technical scheme of this patent is described in more detail.
Referring to Fig. 1, a kind of cable trench ventilating device, comprises the casing 7 being arranged on cable trench 9, is provided with some cable beareves 10 in cable trench 9, and cable is distributed on cable bearer 10 respectively; Casing 7 side is provided with case door 12, and Zuo Bi, You Bi of described casing 7 are respectively equipped with some ventilation holes, and the bottom surface of described casing 7 is provided with a grille mounting 8, and on grille mounting 8, interval is provided with some semi-conductor cooling piece groups 11; Wherein the cold junction of semi-conductor cooling piece group 11 is down, and hot junction is upward; The roof 3 of described casing 7 is obliquely installed, the top of roof 3 is provided with solar panel 1, solar panel 1 be arranged on the charging controller 2 inside roof 3 and store battery is connected, described semi-conductor cooling piece group 11 is connected with store battery by controller, the rear wall of casing 7 is provided with ventilation opening 4, described ventilation opening 4 place is provided with ventilation plant, and the outside of described ventilation opening is provided with the grid 5 that keep off the rain.
In a kind of preferred embodiment of the present utility model, described ventilation plant is the exhaust fan 6 being arranged on inside ventilation opening, and described exhaust fan 6 is electrically connected with automatic control device. Described automatic control device is temperature sensor;
In a kind of preferred embodiment of the present utility model, described roof 3 near the side of case door 3 lower than another side.
Because ventilation casing uses in equipment district, exposing to the weather and drench with rain, so should select to make simply, sturdy and durable, the aluminium sheet not easily got rusty is as the material of ventilation casing casing; Cable trench 9 ventilation casing to be played maximum effect and just must be opened by exhaust fan, and this just needs to provide power supply to exhaust fan 6. Power supply needed for exhaust fan 6 is alternating current 220V voltage, adopts the method solution drawing cable at maintenance power supply case; The work of certain exhaust fan 6 can realize automatic control, as control exhaust fan 6 by set temperature sensor work whether, in use, the semi-conductor cooling piece group arranged bottom casing can generate cold air in cable trench and form cold heat exchange convection current, reduce the temperature in cable trench so that in cable trench, temperature is still in normal level when sweltering heat in summer.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned enforcement mode, in the ken that one skilled in the relevant art possesses, it is also possible under the prerequisite not departing from this patent objective, make various change.
