Description
Technical field
It the utility model is related to a kind of goaf pressure release skylight, and in particular to a kind of safety of goaf pressure release skylight well head
Protection device.
Background technology
To prevent goaf unstability induces air-shock wave from being damaged to underground operators, generally from earth's surface construction one
Bar vertical shaft（Or inclined shaft）Straight-through goaf, utilizes the vertical shaft（Or inclined shaft）Drain goaf in compressed gas, reduce to underground its
The impact of its operating area, the vertical shaft（Or inclined shaft）Referred to as pressure release skylight.Pressure release skylight connects earth's surface and goaf, its earth's surface one
End is generally in open or semi-open state, and potential safety hazard is very prominent.When goaf top plate inbreak, the air-impingement of formation
Ripple discharges earth's surface with extremely strong pressure from pressure release skylight, and now well head near zone is extremely hazardous region, people, thing in this region
Larger threat will all be faced；Use simple covering treatment at the well head of pressure release skylight, overcover intensity is small, easy movement, ground
For the humans and animals of upper walking once falling goaf from well head, consequence is hardly imaginable；Rainwater season rainfall is big, surface water and mud
Sand may be poured in down a chimney underground by pressure release skylight, form downhole debris flow disaster, or even cause to flood well thing without special drain passage
Therefore.
Utility model content
The purpose of this utility model is to provide a kind of safety guard for closing pressure release skylight well head, to avoid
People, thing prevent surface water, silt from pouring in down a chimney underground close to well head.
The safety guard of this goaf pressure release skylight well head provided by the utility model, mainly include well head and close
Component, well head closed component include the hollow circular cylinder of upper and lower opening and are attached to the capping at end, and hollow circular cylinder is fixed
In the periphery of well head on ground, capping closes well head after being connected on hollow circular cylinder, and capping is connected with the anti-component that flies out.
The hollow circular cylinder and capping are precast concrete, cover the circular arc for evagination.
There is annular groove the upper surface of the hollow circular cylinder, is set in annular groove along the spacing of hollow circular cylinder radial direction
Muscle.
The downside of the capping, which corresponds to, downward bulge loop at the annular groove, have on bulge loop corresponding with the limit rib
Neck.
Pre-buried upward joint bar is fixed on the concrete pedestal and pedestal that the lower end of the hollow circular cylinder passes through ground,
The reserved spliced eye vertically in the lower end of hollow circular cylinder.
Lifting bolt is embedded with the concrete pedestal.
On the upside of the capping or periphery is embedded with lifting bolt, by strengthened rope and is hung between capping and concrete pedestal
Ring screw is connected as a single entity.
The upper end of the hollow circular cylinder sets connection ear mount, and card ear is set in capping, connects and leads between ear mount and Ka Er
Cross hinge.
The utility model provides two kinds of technical schemes, and a kind of scheme is that one is plugged between capping and hollow circular cylinder
Body, by hollow circular cylinder by concrete pedestal fix stably, the circumference movement of capping is constrained by limit rib, passes through strengthened rope
Capping and pedestal are connected, when air-shock wave raises capping constraint capping distally move, avoid its from out of control flying out
Hurt sb.'s feelings.Another scheme is articulated as one between capping and hollow circular cylinder, and articulated structure can guarantee that capping not by shock wave
Go out and hurt sb.'s feelings.
The well head of pressure release skylight is used the closed component with some strength to be closed by the utility model, by closed group
The hollow circular cylinder of part fixes with ground, while also ensures that the capping of closed component will not fly out and hurt sb.'s feelings, and so avoids completely
To people near well head and build（Structure）Build the injury of thing.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the schematic top plan view of cylinder in Fig. 1.
Fig. 3 is the elevational schematic view covered in Fig. 1.
Embodiment
Embodiment one, as shown in Figure 1 to Figure 3, the safety guarantor of this goaf pressure release skylight well head disclosed in the present embodiment
Protection unit, the well head of main hollow circular cylinder 1 and the formation of capping 2 for being connected to the upper end of hollow circular cylinder 1 including upper and lower opening
Closed component.The hollow circular cylinder 1 of the present embodiment and capping 2 use precast concrete.
The lower surface of hollow circular cylinder 1 is circumferentially arranged to be had some along its axial spliced eye, and there is annular groove upper surface
31。
The lower end of hollow circular cylinder 1 is fixed by the concrete pedestal 3 of annular.Concrete pedestal 3 when prefabricated it is pre-buried upward
Joint bar 4, the position of joint bar 4 and quantity are corresponding with the spliced eye on hollow circular cylinder 1.Hollow circular cylinder 1 passes through its lower end
Spliced eye and joint bar 4 are connected.
Capping 2 is the circular arc of evagination, and its downside, which is corresponded at the annular groove on hollow circular cylinder 1, downward bulge loop
21。
During the installation of capping 2, bulge loop 21 is inserted in annular groove.It is mobile in order to limit the circumference of capping 2, as shown in Fig. 2
Some limit ribs 11 along the radial direction of hollow circular cylinder 1 are set in annular groove 31.Certainly, corresponded in capping 2 at limit rib 11
Corresponding socket need to be set.
In order to avoid capping 2 flies out under the shock wave in goaf and hurted sb.'s feelings, the present embodiment on concrete pedestal 3 and
Pre-buried lifting bolt 5 is distinguished in capping 2, the lifting bolt 5 that will be covered by strengthened rope 6 on 2 and on concrete pedestal 3 is linked as one
Body.Two lifting bolts and strengthened rope form the anti-component that flies out of the present embodiment.
In order to prevent humans and animals from entering well head near zone, set in the periphery of well head closed component and be higher than skylight well head
The enclosure wall 9 of Surrounding Mountainous Areas.Enclosure wall is also prevented from rainwater, mud-rock flow etc. and poured in down a chimney to underground.In addition to it is easy to professional couple
Checked or repaired at well head, the door that a fan is locked is opened on enclosure wall.For the ease of excluding the water in enclosure wall, in enclosure wall
Bottom opens up osculum.
Embodiment two, as shown in figure 3, the present embodiment and the difference of embodiment one are：The upper end edge week of hollow circular cylinder 1
To some connection ear mounts 7 are set, corresponding connection otic placode is set in the periphery of capping 2, by through connection ear mount and engaging lug
The bearing pin 8 of plate will cover and hollow circular cylinder is articulated as one, and avoids capping from being flown out and hurted sb.'s feelings due to the impact of shock wave.Connection
Ear mount, connection otic placode and bearing pin form the anti-component that flies out of the present embodiment.
