Description

A kind of lower well falling proof device

Technical field

The utility model belongs to urban operating mechanism technical field, in particular to a kind of lower well falling proof device.

Background technique

Municipal Sewage well cover is movably arranged at the opening of sewer for the convenience of maintenance construction, and when rainstorm weather is led When causing excessive rainfall in sewer, entire sewer pipe network water pressure increases, so that powerful hydraulic pressure rushes well lid upwards, so that well Lid is detached from or misplaces from well head, sometimes there is also Sewage well cover damage or stolen situation, people easily occurs or object falls to and is lauched The risk of road pipe network.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of lower well falling proof device, including it is set to lower well The hook for building the following borehole wall, be connected to hook on protection net, the protection net be with perforated reticular structure, it is described Linking up with includes hanger bulk, inflection section, connection pin shaft, active catch, is equipped with and is open among inflection section end, in the opening Equipped with lateral connection pin shaft, it is sheathed on connection pin shaft and is equipped with rod-shaped active catch, rod-shaped active catch can be around connection pin shaft rotation, bar When shape active catch end is turned in hanger bulk, mutually overlapped with hanger bulk.

Preferably, the protection net can be the tightrope net or rigid plastics net of eyelet.

Preferably, recess is equipped with active catch overlapping part in the hanger bulk.

Preferably, the rod-shaped active catch is made of magnetic material.

Well falling proof device under the utility model, protection net firmly install, and are not easy to fall, and lose, and repair lower well When, protection net is removed conveniently, and construction personnel is facilitated to enter lower water well drilling；When Sewage well cover is lost, protection net prevents people Member falls into lower well, protects personal safety.

Specific embodiment

Embodiment 1

As shown in Figs 1-4, the utility model discloses a kind of lower well falling proof devices, including are set to below Sewage well cover The hook 1 of the borehole wall, the protection net 2 being connected on hook 1, the protection net 2 are with perforated reticular structure.

The hook 1 includes hanger bulk 14, inflection section 11, connection pin shaft 12, active catch 13,11 end of inflection section Centre is equipped with opening 17, is equipped with lateral connection pin shaft 12 in the opening 17, is sheathed on connection pin shaft 12 and is equipped with rod-shaped activity Gear 13, rod-shaped active catch 13 can be rotated around connection pin shaft 12, when rod-shaped 13 end of active catch is turned in hanger bulk 14, with extension 14 phase of hook ontology overlap joint.

Recess 18 is equipped with active catch overlapping part in the hanger bulk.

The rod-shaped active catch is made of magnetic material.

The protection net 2 can be the tightrope net or rigid plastics net of eyelet.

As shown in fig. 6, the protection net of lower well falling proof device is rigid plastics net.

Setscrew can be equipped with by linking up with tail portion, and hook is fixed on the borehole wall, can be hung on hook by protection net, will be rod-shaped Active catch 13 rides in hanger bulk 14, and rod-shaped active catch is fixed in recess, prevents protection net 2 from falling off, and is lauched in maintenance When road, facilitate and remove protection net, worker enters lower water well drilling；When Sewage well cover is lost, protection net 2 prevents personnel from falling Fall into lower well.

Embodiment 2

As shown in figure 5, the utility model discloses well falling proof device under another kind, embodiment 2 is different from embodiment 1 , the hook includes hanger bulk 14, inflection section 11, and the end of the inflection section 11 is equipped with eyelet 15, with the eyelet 15 phases are equipped with iron wire 16.

In the present embodiment, hook is tied up in hanger bulk 14 by passing through the iron wire 16 of eyelet 15, connects stronger, work When people constructs, iron wire is taken off, protection net is removed.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
