Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a natural draft cable trench cover, including apron frame 1, apron frame 1 puts up stainless steel plate preparation for use, thickness chooses for use as required, heavy groove 3 has been seted up on apron frame 1's top surface, the upper surface mid portion has set up the heavy groove 3 of recessed downwards, make things convenient for the installation of anti-skidding footboard to dismantle, the inner wall of heavy groove 3 is provided with outlet 2, outlet 2 is located breakwater 8 top, the apron both ends are derived to outlet 2 of ponding accessible design on the wall is founded to the recess both sides in the heavy groove 3, prevent ponding in the heavy groove 3, can lead water outside the ditch again, the inboard of heavy groove 3 is provided with step mat 4, step mat 4 is the slipmat, it is together with the frame upper surface plane to install its upper plane behind the slipmat, the outward appearance is pleasing to the eye, support intensity is high, anti-skidding is effectual.

Referring to fig. 2 and 3, a reinforcing rib 7 is arranged at the center of the bottom of the cover plate frame 1, the reinforcing rib 7 is arranged in the middle of the bottom of the cover plate frame 1, the cover plate frame is of a vertical square tube structure, the bearing capacity of the cover plate is increased, the influence on ventilation is reduced as much as possible, the two corresponding ends of the cover plate frame 1 are provided with ventilation openings 5, the direct-opening waterproof edge shielding design is adopted, the wind resistance is reduced as much as possible, the air quantity is increased, the ventilation openings 5 extend to the bottom of the cover plate frame 1, the inner walls of the ventilation openings 5 are provided with dust screens 6, the inner walls of the end face ventilation openings 5 at the two sides are provided with the dust screens 6, the thickness of the screen wires is 1.0mm, the mesh openings are 5 meshes, and foreign sand and stone particles, leaves, weeds, plastics and other impurities outside the ditch can be effectively prevented from entering the ditch.

All be provided with breakwater 8 near vent 5 department in apron frame 1 bottom, breakwater 8 uses the three angle iron preparation, can prevent that the rainwater from instiling into or ground ponding pours into inside the cable pit, form down mouth of a river 9 between breakwater 8 and the vent 5, the breakwater height is less than apron frame 1's height, set up clearance 10 between the apron at breakwater 8 and top, be used for the ventilation, avoid sealing, do not increase the windage as far as possible, water sealing strip can be installed to breakwater 8's bottom, rectangle water sealing strip can be pasted to the baffle downside, prevent effectively that the outer ponding of ditch from getting into in the ditch.
