Description

A kind of Safety well cover

Technical field

The invention belongs to urban operating mechanism, particularly Safety well cover.

Background technology

Present well lid is being met when raining heavyly, is often washed away by water, potential safety hazard is caused to pedestrian, vehicle on road, to understand Certainly this problem, existing many patented technologies, such as：A kind of Safety well cover（The patent No.：2015201492200）, it be with screw, Nut etc. is flexibly connected well lid and well seat get up, and has rushed rising to a certain extent when meeting heavy rain well lid, the screw below well lid On nut will by well seat block, well lid stop rise, will not be washed away by rainwater, now the problem is that well seat periphery be only It press against by road surface, bottom surface and well body top surface are simple fixation, not solid and reliable, rainwater is likely to a well lid, well seat one Rise and wash away.

The content of the invention

It is of the present invention to solve the problems, such as to be adopted the technical scheme that in order to solve this problem：Well inwall correspondence both sides are provided with Vertical well lid protection pull bar, pull bar bottom is welded with opening down centre for the empty long slide plate of " n " shape by borehole wall side, long The empty middle part of slide plate is long slideway, has the upper middle part fixed by screw to have the baffle plate of circular arc that " n " shape is long on the inside of long slide plate following Slide plate under shed is sealed, and protection pull bar is long 15-60 centimetres, and the long skateboard ramp of " n " shape is long 10-40 centimetres, and the long slide plate of " n " shape is slided Setscrew is fixed with the correspondence borehole wall of road top, expanding screw screw mandrel grows 10-15 millimeters of the nut of fixed expansion screw, slideway Width is bigger than setscrew shank diameter 1-6 millimeters, the screw rod that long skateboard ramp movable set is grown in fixed expansion screw nut On, then be screwed in a nut compress long slide plate on the setscrew screw rod grown after unlay, so that long slide plate can go up downslide It is dynamic, annular guider ring is welded with the outside of protection pull bar, with correcting pull bar, guider ring is more than long slide plate to well head distance and slided Road length, well lid has well lid opening and the tubaeform well lid eye corresponding with protection pull bar, and there is counterbore on well lid eye top, and well lid is prevented Shield pull bar top has screw thread and tightens the nut on screw thread, and nut falls in well lid counterbore.When meeting when raining heavyly, rainwater has rushed well Lid, due to there is a guider ring, the steady raising of well lid, playing an emersion well head to a certain extent will be by the long slide plate of " n " shape below pull bar Setscrew pole spacing in slideway is lived, and well lid stops raising, and rainwater can then be gushed out with the raising of well lid, and at this moment pull bar is led Positive ring is still in well head, and well lid drops back into original position under self gravitation effect after playing correcting, rainwater, when needing opening well lid When, head nut on pull bar is backed out, acts well lid upwards by well lid opening, during manhole cover, tubaeform well lid eye is easy to Well lid aligns placement.

Well lid of the present invention meets well lid with setscrew, guider ring, the long slide plate of " n " shape etc. the impact being subject to when flood falls and rushed Power is transferred on the borehole wall, and the borehole wall is fixed, and the strength that can be born is big, thus it is more safe and reliable, firm, and It can implement on existing well, well seat, practicality is wide.

Fig. 2 is partial sectional view, the partial enlarged drawing of well lid C direction views of the present invention and C direction views.

Embodiment

A kind of Safety well cover includes：1st, well lid, 2, well lid eye counterbore, 3, pull-rod nut, 4, tubaeform well lid eye, 5, protection Pull bar, 6, the long slide plate of " n " shape, 7, setscrew, 8, guider ring, 9, well lid opening, 10, baffle plate, well inwall correspondence both sides are set There is vertical well lid protection pull bar 5, the bottom of pull bar 5 is welded with opening down centre by borehole wall side and slided for empty " n " shape length Plate 6, the empty middle part of long slide plate 6 is long slideway, and there is 10, the baffle plate of circular arc at the upper middle part that the long lower inside of slide plate 6 has screw to fix The long under shed of slide plate 6 of " n " shape is sealed, and protection pull bar 5 grows 50 centimetres, long 30 centimetres of the 6 slideway length of slide plate of " n " shape, slideway top pair Answer and setscrew 7 is fixed with the borehole wall, expanding screw screw mandrel grows 12 millimeters of the nut of fixed expansion screw 7, and chute width is than swollen Swollen screw shank diameter is big 4 millimeters, and the long slideway movable set of slide plate 6 is on the screw rod that the nut of fixed expansion screw 7 is grown, then uses One nut is screwed on the screw rod grown compress long slide plate 6 after unlay, so that long slide plate 6 can be slided up and down, protection pull bar 5 outside Side is welded with annular guider ring 8, and guider ring 8 to well head distance is 32 centimetres, and protection pull bar 5 is corresponding through well lid 1 Toroidal well lid eye 4, there is counterbore 2 on the top of well lid eye 4, and the well lid protection top of pull bar 5 has screw thread and the spiral shell being tightened on screw thread Mother 3, nut 3 falls in well lid counterbore 2.During installation, first installed in borehole wall correspondence both sides from the centimeters of well head 50.8 and fix 16 Setscrew, " n " shape long slide plate 6 below the pull bar 5 being welded and fixed is inserted on the corresponding expanding screw screw mandrel of the borehole wall, then It is fixed together with key screw baffle plate 10 and the long following of slide plate 6 of " n " shape, the long under shed of slide plate 6 of " n " shape is sealed, then again swollen A nut is screwed in swollen lead screw, tightens and unlays, last tubaeform well lid eye 4 aligns pull bar 5 and well lid 1 is placed on well head On, screw on and tighten head nut 3 on pull bar 5.When meeting when raining heavyly, rainwater has rushed well lid 1, and due to there is guider ring 8, well lid 1 steadily rises Rise, playing emersion well head will be lived by the setscrew pole spacing in the long slideway of slide plate 6 of " n " shape below pull bar 5 to a certain extent, well Lid 1 stops raising, and rainwater can then be gushed out with the raising of well lid 1, and at this moment pull bar guider ring 8 is still in well head, from well head 3.6 centimetres, well lid 1 drops back into original position under self gravitation effect after playing correcting, rainwater, when needing to open well lid 1, twists Lower pull-rod nut 3, acts well lid 1 upwards by well lid opening 9, during manhole cover 1, and toroidal well lid eye 4 is easy to well Lid 1 aligns placement.
