Abstract
The utility model relates to a safety protection device of a steel fiber catch basin, which aims to solve the safety protection problem of the catch basin. The steel fiber safety protection device comprises a steel fiber catch basin seat arranged at a catch basin opening; the catch basin seat is provided with a circle of inner edge; the inner edge is provided with a plurality of hooks in a removable way; the hooks are fixedly provided with a safety protection net which can cover the catch basin opening and comprise a straight part and a bending part; the straight part is provided with a blocking edge; the lower part of the blocking edge is provided with threads; each hook is also provided a nut which matches with the straight part of the hook through threads; the inner edge of the catch basin seat is provided with a through hole; and the hooks penetrate through the through hole and is then fixedly arranged on the inner edge of the catch basin seat through the nut and the blocking edge; and the hooks are arranged with identical intervals along the periphery of the inner edge. The utility model has the following advantages: the catch basin seat is provided with the safety protection device, thereby effectively preventing pedestrians from falling into the catch basin with no cover and protecting the safety of the sewer maintenance personnel; the safety protection net is solid and reliable, and can be conveniently disassembled and assembled; and the hooks have a reasonable structure and can not fall off.
Description
Affiliated field
The utility model relates to a kind of safety device, specifically is meant to be used to prevent that the pedestrian from falling into the steel fibre inspection shaft safety device of inspection shaft.
Background technology
Modern city underdrainage pipe network is crisscross, inspection shaft is densely distributed, and inspection shaft is distributed in the residential block with on the big road of visitors flowrate more, present inspection shaft covers big multidigit cast iron quality, stolen easily, the incident that the pedestrian falls into the uncovered inspection shaft happens occasionally, cast iron inspection shaft lid is substituted by steel fiber reinforced concrete manhole top gradually now, and steel fiber reinforced concrete manhole top is because the material cheapness is difficult for stolen, but when sewer overhauls, the inspection shaft lid is removed, and still can cause very big potential safety hazard to the pedestrian, and ground foreign material is fallen into inspection shaft easily, bring personal injury to the maintainer easily, inspection shaft security protection problem needs to be resolved hurrily.
Summary of the invention
In order to solve inspection shaft security protection problem, the utility model provides a kind of steel fibre inspection shaft safety device with protective screening.
The technical solution adopted in the utility model is:
A kind of steel fibre inspection shaft safety device comprises the steel fibre inspection shaft seat that is installed in the inspection shaft aperture, and described inspection shaft seat has a circle inner edge, removablely on the inner edge is connected with some hooks, is fixed with the safety guard net that the inspection shaft aperture can be covered on the hook.
Hook comprises vertical portion and kink, the vertical portion has the retaining edge, and retaining edge below is provided with screw thread, and hook also is provided with and links up with the nut of vertical portion threaded engagement, inspection shaft seat inner edge is provided with through hole, and hook passes through hole and is fixed on the inspection shaft seat inner edge by nut and the cooperation of retaining edge.
Described hook is arranged along inner edge is circumferentially equidistant.
Described safety guard net is worked out by nylon rope, and the edge nettle can be fastened with the hook kink.
The beneficial effects of the utility model are: on the inspection shaft seat safety device is set, effectively avoids the pedestrian to fall into the generation of uncovered inspection shaft incident and protection sewer maintainer's safety; Solid and reliable, the easy accessibility of safety guard net; Hook structure is reasonable, can not come off.
