Embodiment：
In consideration of it, the invention provides a kind of ventilation dewetting well cover of cable well, below in conjunction with Figure of description to the present invention
Preferred embodiment illustrate.
Refering to shown in Fig. 1 to Fig. 4, a kind of ventilation dewetting well cover of cable well, including：Guide rail 1, well lid 2, walling crib 3 and branch
Strut 4；Guide rail 1 includes the annulus 101 that top is fixed on cable shaft well head inwall, and the inner edge of annulus 101 sets groove, annulus
101 bottoms are uniformly arranged four vertical guide grooves 102, and groove connects with the inside of guide groove 102；Well lid 2 and the hinge connection of walling crib 3,
Walling crib 3 is annular shape, and above guide rail 1, the bottom of walling crib 3 is uniformly arranged four vertical support bars 4, and the lower end of support bar 4 is all
Sliding block 401 is fixedly connected with, four sliding blocks 401 coordinate with four guide grooves 102 respectively to be installed；The inner edge groove of annulus 101 and guide groove
102 connectivity part, and in groove, side fixed setting baffle plate 103, opposite side sets detachable block piece 104；It will stop
Part 104 is removed, and sliding block 401, which is slid up in guide groove 102 in the groove of the inner edge of annulus 101, to horizontally rotate, and turned to
After being stopped by baffle plate 103, block piece 104, the fixed position of walling crib 3 are installed；Formed between the adjacent supports bar 4 of the bottom of walling crib 3 logical
Air regulator.
Wherein, the top of well lid 2 sets handle 201, is easy to staff to lift.Handle 201 can stretch up and down, when lifting
Elongation, when putting down, the downside of retraction well lid 2, further contemplate well lid 2 and be possible to be opened by passerby, potential safety hazard, well lid be present
Cam lock 202 is set at 2 aperture position, and the lock core of cam lock 202 is regular polygon, sets diameter to be more than outside lock core just polygon
The annulus of shape circumscribed circle, it is fixed on well lid 2.Regular hexagon is it is preferably provided as, the circle diameter that outside installs additional is slightly larger than positive six
The circumscribed circle of side shape, being used could be opened using special opener, reach safe purpose.
Due in larger distance between four support bars 4, the space reserved might have child and fall into accidentally, using wire netting
Shape structure, flexural deformation can be produced after long-time use, well lid 2 may be caused not transfer to well, therefore, window position of divulging information
Shutter is installed, the blade 403 of shutter is made using steel plate, and four bottoms of support bar 4 are provided for connecting the circle of blade 403
Shape fixed plate 402, blade 403 is perpendicular to walling crib 3, and the lower surface inside edge position of walling crib 3 is fixed in one end, and fixation is fixed in one end
The upper surface of plate 402.Each blade 403 is 15 ° to 20 ° with the angle of the tangent line on the corresponding inside edge of walling crib 3.
Sliding block 401 is pulley, and the axle of pulley is fixed on the lower end of support bar 4 by connecting rod.Using for a long time will not also produce
Raw bite problem.
Detachable block piece 104 is lockset, and the side of sliding block 401 is stopped by baffle plate 103, the annulus of the opposite side of sliding block 401
Lockhole 105 is set on 101, and for fixing lockset, passerby just can not random lift manhole lid 2.
In the season that needs are divulged information, well lid 2 understands 24 hours one day all in the state lifted, for the peace of night pedestrian
Entirely, reflecting coating is coated with outside well lid 2.
In use, lifting the handle 201 on well lid 2, the sliding block 401 of the related bottom of support bar 4 of well lid 2 lifts, sliding block 401
The upward sliding in guide groove 102, when can not be lifted up again, if baffle plate 103 is arranged on the position on the left side of support bar 4,
Portable well lid 2 to the left, that is, is rotated clockwise to after baffle plate 103 blocks sliding block 401 and put down, then lock is pinned, in sliding block 401
Right side formed stop, ensure well lid 2 rise when position fix, be not susceptible to change.Need under the well lid 2 by ventilation state
When putting, lock is first opened, lifts the handle 201 on well lid 2, rotates counterclockwise to guide groove 102, transferred, then be by lock pinning
Can.When needing maintenance, by special opener, the cam lock 202 on well lid 2 is outwarded winding, passes through the handle 201 on well lid 2
Lift.
