The specific embodiment
Below in conjunction with drawings and Examples, describe embodiment of the present utility model in detail.
Embodiment mono-
A kind of municipal sewage system well mouth protector, the retainer that is fixed on well head 1 that comprises annular, below retainer 1, be equidistantly connected with a plurality of hydraulic tubes 4 perpendicular to its place face, in hydraulic tube 4, there are piston 5 and push rod 6, push rod 6 bottoms connect piston 5, and stretch out from the top of hydraulic tube 4 on top.
In this structure, when piston 5 has certain distance ，Dang down-hole to have water with inside pipe wall in hydraulic tube 4, rely on buoyancy of water that piston 5 is upwards pushed away, drive push rod 6 to stretch out hydraulic tube 4, finally reach well head, rounded around well head, pedestrian is warned.
Embodiment bis-
Consider that buoyancy of water is not enough to promote piston 5 as a rule, therefore the structure of embodiment mono-is upgraded.
As shown in Figure 1, Figure 2 and Figure 3, hydraulic tube 4 bottoms are connected to submersible pump 11 by conduit under fluid pressure 10, hydraulic tube 4 is arranged on retainer 1 by mounting blocks 9.The lower end of hydraulic tube 4 arranges sealing ring 7 and end connector 8, and end connector 8 is fixing by screw 13 and nut 14.
At shaft mouth side, along well lid lay down location, be provided with pressure sensor, outer setting at hydraulic tube 4 has liquid level sensor, the output of described pressure sensor and liquid level sensor all connects the control module of submersible pump 11, and when two output conditions all meet when default, control module is controlled and started submersible pump 11.
The toroidal frame that the rear connection of hydraulic tube 4 is positioned at the top of retainer 1 is stretched out on the top of push rod 6, and there is draw-in groove retainer 1 top, and the bottom of toroidal frame is stuck in draw-in groove.The top of toroidal frame is uniformly-spaced connected with column 2, has the protective screening 3 with hole between adjacent column 2, and unloading hole is arranged at hydraulic tube 4 tops.
This structure has realized automatic control, utilizes hydraulic thrust power that piston 5 and push rod 6 are upwards pushed away, and specific works principle is as follows:
When well lid not time, pressure sensor sends signal to control module, now, control module starts receiving liquid level sensor signal and it is judged, when liquid level reaches preset value, control module output signal control relay switch opens submersible pump 11, draw water on the spot and input to conduit under fluid pressure 10, arrive again hydraulic tube 4, piston 5 is produced to motive force, promote piston 5 and push rod 6 and move upward, push rod 6 drives toroidal frame to depart from retainer, together with column 2, protective screening 3, rise to outer wellhead, protective screening 3 can play better warning function.When piston 5 is during higher than unloading hole on hydraulic tube 4, submersible pump 11 is confessed pressure and with unloading hole loss pressure differential, protective screening 3 is held up in stable state, and submersible pump 11 can not transship.Now hydraulic pressure no longer upwards promotes piston 5.
Embodiment tri-
Consider that this application of installation is in the more severe place of condition, if power-off can cause that the warning part of device drops suddenly, therefore the structure of embodiment bis-is upgraded.
The hook lock device 12 that is provided with hinge type structure on well head sidewall, the latch hook of hook lock device 12 is connected in hook lock device body upward and by rotating shaft, can on vertical plane, be 180 ° of rotations.
As shown in Figure 4 and Figure 5, in protective screening 3 uphill process, hook lock device 12 is in contact with one another in " facing upward " state with protective screening 3, when protective screening 3 is pushed to working depth and no longer rises, the latch hook of hook lock device 12 falls, and is stuck on certain hole of protective screening 3 or the bottom of toroidal frame, and the object of hook lock device 12 is to prevent easily power-off after heavy showers, submersible pump 11 cuts out, and protective screening 3 falls without pressure support ventilation; Under 12 protections of this hook lock device, effective hook protective screening 3 during power-off, normally enables whole safeguard function.When water level drops to safe altitude, or during manhole cover, only need the manual protective screening 3 that put down.
Embodiment tetra-
A kind of municipal sewage system well mouth protector, the hydraulic tube 4 that comprises a plurality of longitudinal settings, the lower end of hydraulic tube 4 connects submersible pump 11 by conduit under fluid pressure 10, conduit under fluid pressure 10 bottoms are ring-type, protrude upward a plurality of arms and be connected to hydraulic tube 4, in hydraulic tube 4, there are piston 5 and push rod 6, push rod 6 bottoms connect piston 5, top is fixedly attached to annular retainer 1 below from stretch out the upper end of hydraulic tube 4, at shaft mouth side, along well lid lay down location, be provided with pressure sensor, outer setting at hydraulic tube 4 has liquid level sensor, the output of described pressure sensor and liquid level sensor all connects the control module of submersible pump 11, when two output conditions all meet when default, control module is controlled and is started submersible pump 11.
In this structure, conduit under fluid pressure 10 bottoms are fixed on ground, and hydraulic tube 4 is also vertically fixing, and while upwards promoting, retainer 1, push rod 6, piston 5 make progress together.
Embodiment five
A kind of municipal sewage system well mouth protector, comprise and be fixed on the ground base in shaft bottom, this base is comprised of the outer cylinder body of hollow and the inner barrel of hollow, the top closure of inner barrel, the lower end of outer cylinder body connects on the ground by leg, it between adjacent leg, is water inlet path, the edge that extend in oriented its axle center, top of outer cylinder body, between this edge and the top of inner barrel, there is gap, between cylinder inboard wall and inner barrel outer wall, be provided with annular air inflation water wing outside, the chi footpath, cross section of air inflation water wing is greater than described gap, above air inflation water wing, be uniformly-spaced provided with column 2, between adjacent column 2, there is the protective screening 3 with hole.
In this structure, can make full use of buoyancy of water, air inflation water wing is stuck between inside and outside cylindrical shell, the water inlet path water inlet of outer cylinder body bottom, air inflation water wing is easy to floating, drives column 2, protective screening 3 vice division chief's well head together, when water takes off, without buoyancy, air inflation water wing falls again under Action of Gravity Field.The gap of inside and outside cylinder top can avoid air inflation water wing to depart from control.
Embodiment six
On the basis of embodiment five, the path of intaking connects submersible pump 11 by conduit under fluid pressure 10, at shaft mouth side, along well lid lay down location, be provided with pressure sensor, outer setting at hydraulic tube 4 has liquid level sensor, the output of described pressure sensor and liquid level sensor all connects the control module of submersible pump 11, when two output conditions all meet when default, control module is controlled and is started submersible pump 11.
This structure is also utilized hydraulic thrust power, promotes air inflation water wing and rises, and avoids only not enough so that the phenomenon of its rising by buoyancy of water.
Fig. 6 has expressed the use state of the utility model protector, and in figure, A represents this device, its can well lid not time, provide the protective screening of rising to carry out early warning, to avoid pedestrian and vehicle to be strayed into sewer.
