Abstract
The utility model discloses a ventilative cable trench cover, which comprises a cover plate, the width of apron is greater than the width of cable pit, be provided with the bleeder vent on the face of apron, the below of apron is provided with unable adjustment base around, respectively the interior apron of the type of falling V that is provided with between the unable adjustment base of front and back, be provided with the upwards protruding air vent that just is higher than interior apron face on the interior apron. The utility model discloses have waterproof nature and gas permeability concurrently, both can prevent that the rainwater from flowing in the cable pit, can let cable pit and external intercommunication each other again, make things convenient for the moisture in time to discharge, the inside humidity of reduce the terminal box, overhauing power supply box and local control cabinet etc. The reduction is milden and rot, is wet, the probability of short circuit, has improved power equipment's life -span and reliability greatly.
Description
Technical field
The utility model relates to a kind of trench cover of cable trough, particularly relates to a kind of ventilative cable channel cover plate.
Background technology
The trench cover of the cable trough of current use is normal concrete trench cover, the function of trench cover mainly covers cable trough, water and foreign material are not allowed to drop in cable trough, seal comparatively tight between trench cover and cable trough, lack scavenge duct, in cable trough, gas fluidity is poor, to emerge at the bottom of ground moisture at high humidity or more area of raining, moisture constantly increases, cause cable trough humidity to increase when poor fluidity, cause the cable top layer in cable trough mouldy, reduce the service life of cable; On the other hand, because the devices such as breaker terminals case, maintenance power box and on-site control are arranged along cable trough, if cable trough humidity is excessive, moisture can penetrate the devices such as terminal box, maintenance power box and on-site control along cable, the interior humidity of these devices is increased, what affect described device drives tide, and severe patient can cause internal short-circuit, and impact normally runs.
Utility model content
Technical problem to be solved in the utility model is, overcomes the above defect, provides a kind of reasonable in design, trench cover that structure has the cable trough of sealing and gas permeability concurrently simply, simultaneously.
In order to solve the above technical problem, ventilative cable channel cover plate described in the utility model, comprise cover plate, the width of described cover plate is greater than the width of cable trough, the plate face of described cover plate is provided with air-vent, forward and backward below described cover plate is respectively arranged with firm banking, between described forward and backward firm banking, be provided with reverse V-shaped inner cover plate, described inner cover plate is provided with to raise up and higher than the air vent hole in inner cover plate plate face.
As improvement, cover plate described in the utility model from centre with the flexibility of 4-6 ° to two lateral bends; The air-vent of described cover plate and the air vent hole of described inner cover plate stagger mutually.
Further, the diameter of air-vent described in the utility model and air vent hole is 0.8-1.2cm.
Trench cover described in the utility model adopts inside and outside two-layer design, cover plate, inner cover plate are provided with the hole of mutually staggering, on the one hand cable trough and the external world are interconnected, the moisture in cable trough is facilitated to discharge in time, the devices such as protection cable, terminal box, maintenance power box and on-site control, extend its useful life, reduce dangerous; On the other hand, cover plate, inner cover plate are provided with the hole of mutually staggering, and air vent hole raises up and higher than inner cover plate plate face, as rain enters through air-vent, also can not flow in cable trough, but flow to cable trough from reverse V-shaped inner cover plate both sides, solve sealing and ventilative problem well.
The beneficial effects of the utility model: the utility model has reasonable in design, advantages of simple structure and simple, not only waterproof, and it is ventilative, the interior humidity of cable trough, terminal box, maintenance power box and on-site control etc. can be reduced, thus decrease go mouldy, make moist, the probability of short circuit, substantially increase life-span and the reliability of power equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model is secret states ventilative cable channel cover plate, comprise cover plate 1, the width of described cover plate 1 is greater than the width of cable trough, the plate face of described cover plate 1 is provided with air-vent 2, forward and backward below described cover plate 1 is respectively arranged with firm banking 3, between described forward and backward firm banking 3, be provided with reverse V-shaped inner cover plate 4, described inner cover plate 4 be provided with and raise up and higher than the air vent hole 5 in inner cover plate plate face.
As improvement, cover plate 1 described in the utility model from centre with the flexibility of 4-6 ° to two lateral bends; The air-vent 2 of described cover plate 1 staggers mutually with the air vent hole 5 of described inner cover plate 4.
Further, the diameter of air-vent 2 described in the utility model and air vent hole 5 is 0.8-1.2cm.
Embodiment: cover plate 1 described in the utility model, inner cover plate 4, firm banking 3 are stainless steel material, for realizing the gas permeability of trench cover, cover plate 1, inner cover plate 4 is all beaten the hole of diameter 1cm, both ventilative, can prevent again toy from entering cable trough; In order to anti-sealing enters in cable trough, the air-vent 2 of described cover plate 1 and the air vent hole 5 of described inner cover plate 4 stagger 3-5cm mutually, air-vent 5 in described inner cover plate 4 takes the mode of punching from bottom to top, projecting plate face, edge is made to be about 0.5cm, and be directed upwardly, ensure that water flows to outside ditch along inner cover plate 4; The width of described cover plate 1 is determined according to the width of cable trough, and usually slightly large than cable trough width, it is unsettled outside cable trough that both sides of the edge are about 3cm, facilitates rainwater to flow to outside ditch; In order to current flow to outside the earth more easily, described cover plate 1 from centre with the flexibility of 5 ° to two lateral bends, the outer surface of cover plate 1 is made to be cambered surface, the forward and backward each welding firm banking 3 below described cover plate 1, inner cover plate 4 reverse V-shaped in welding between two firm bankings 3.
These are only a kind of execution mode of the present utility model, as long as employ the above structure, protection range of the present utility model all should be fallen into.
