Detailed description of the invention
With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings:
Embodiment one:
As it is shown in figure 1, the well lid of inspection shaft of the present utility model, well lid is circular, including fixing lid 3 and unlatching lid 4, Gu
Surely lid 3 is fixedly mounted at the upper opening of pit shaft 2 of inspection shaft, and fixed form can use riveting or can be integrated with pit shaft
Manufacturing, it is less that fixing cover accounts for area, and its arc angle can be 90 °～the scope of about 150 °.Open lid 4 with fixing
Lid 3 is connected by external damp hinge 18, and external damp hinge 18 can effectively prevent rain sewage, tide in drainage pipeline
The humid air corrosion to hinge member.Additionally damp hinge also allows maintainer's open manhole cover of pipe gallery more laborsaving, opens
Lid 4 can be the most upright after opening, it is simple to maintainer operates further.Open lid 4 and be provided with handle lock 17, it is simple to open
The opening and closing of lid 4.
Fixing lid 3 is provided with liquidometer 5 and breather 6, liquidometer 5 and breather 6 and is all arranged in fixing lid 3, with pit shaft
Space in 2 is connected, and liquidometer can measure underground water level, and breather picks out from fixing lid, can be connected to the logical of pipe gallery outfit
Wind devices (or being connected to the miniature ventilation pump arranged specially).As depicted in figs. 1 and 2, liquid level safety pole 7 is arranged on liquidometer
5 places contacted with fixing lid 3, one end of liquid level safety pole 7 is rotatably connected with liquidometer 5, and the other end is to opening lid
4 extend, and liquid level safety pole 7 is parallel with the plane opened residing for lid 4.Exhaust, safety bar 8 is arranged on breather 6 and fixing lid
3 places contacted, one end of exhaust, safety bar 8 is rotatably connected with breather 6, and the other end is to opening lid 4 extension, row
Gas safety pole 8 is parallel with the plane opened residing for lid 4.
Liquidometer 5 can use ultrasonic level gage or other kinds of liquidometer matured product, but answers the exportable signal of telecommunication, uses
In the rotation controlling liquid level safety pole 7.Breather 6 is equipped with switch and the timer that can open ventilation installation, opens ventilation and sets
Timer i.e. time synchronisation after standby switch, when running between reach setting value after, timer output the signal of telecommunication, be used for controlling
The rotation of exhaust, safety bar.The design of double safety poles be only enter inspection shaft maintainer safely provided great guarantor
Barrier, when the mechanical caging of safety pole simultaneously is also for preventing high water level, well lid is rushed to open backing up of sewage and adds one layer of guarantee.
When needs enter inspection shaft: 1, open liquidometer and carry out reading, liquid level is less than setting value, is i.e. judged as overflowing into
Pipe gallery cabin, now liquid level safety pole 90-degree rotation counterclockwise；If higher than setting value, safety pole locking cannot rotate.
2, ventilation installation or the miniature ventilation pump that breather is connected is started, after the time reaching to set of bleeding, exhaust, safety bar up time
Pin 90-degree rotation；Not up to duration of ventilation, safety pole locking cannot rotate.3, after double-rod is all rotated in place, handle lock side
Can use, manual unlocking opens lid, and personnel enter.Even if handle lock is artificially unlocked, if liquid level safety pole and aerofluxus peace
Any one of full bar does not rotates, and opens lid and cannot will open because of the mechanical stop of safety pole.
As it is shown on figure 3, fixing lid 3 lower surfaces are provided with illuminating lamp 19, photographic head and detector (not providing in figure),
Wherein illuminating lamp 19 and photographic head all should band explosion prevention functions.Illuminating lamp can facilitate maintainer's work of conveniently going into the well, photographic head
With the access of the equipment such as detector, the later stage can be accessed by the intelligent operation system of pipe gallery, arranges photographic head inside well lid
Monitoring, advantageously in the safety of maintainer, also can more intuitively grasp the operation state of drainage pipeline.Detector and row
Gas safety pole 8 electrically connects, and can not be equipped with the duration of ventilation of timer as signal with breather 6, but pass through detector
The detection gas concentration such as methane, hydrogen sulfide, after concentration is less than setting value, sends the signal of telecommunication, and turn clockwise exhaust, safety
Bar.The abundant functional module set up around fixing lid, is all considered as equipment waterproof.
As it is shown in figure 5, use single slot sealing arrangement between removable cover and fixing lid.Utilize the thickness of well lid, fixing lid 3 with
