It relates to, U-type groove is allow to lock well lid with latch.
In use, first by possessed unlocking mechanism in borehole wall processing cost invention by slot, unlock through-hole,
Fixed locking block structure on burglar-proof mechanism, is mounted on the lock of the borehole wall by well lid mounting surface, the shaft wall structure for locking inside groove first
In tight inside groove, anti-jamming mechanism and burglar-proof mechanism are mounted on well lid enclosure interior, secondly by mounted well lid, by well lid shell
Support leg and the borehole wall on well lid mounting surface match on the borehole wall；Clockwork spring at this time is in nature retracted position；Big lid
There is gap, minor flaps to have cover board and pipe parallel clearance with small effluent pipe mouth between plate and big effluent pipe mouth；Hard spring only by
The gravity factor of latch is in free state；It is arrived across well lid center hole using auxiliary tool during well lid is installed
Unlock through-hole is passed through to be in contact close to the end face of well lid shell on latch segment up in unlock square hole, while using auxiliary tool,
At this moment it is pressed downward latch segment using auxiliary tool, locking hole meets with U-type groove when being depressed into certain distance, at this time using auxiliary
Tool rotates drive shaft, and the U-type groove on latch is made to be stuck on latch segment, removes the installation that auxiliary tool completes well lid.Cause
For there are three circumferential equally distributed burglar-proof mechanisms in the design, so not knowing latch segment how many distance needed to be pressed downward,
It is antitheft to achieve the purpose that or less than being difficult to steal well lid successfully in the case of three people.Well lid shell is reached in flow
When on body, flow impacts large cover and minor flaps respectively from king bolt hole and minor spiral hole, and the impact force that large cover is subject to is big
In the impact force that minor flaps are subject to, anti-jamming mechanism surrounds drive shaft rotary motion under the drive of large cover, to dynamic pressure
Original cover board and pipe parallel clearance supplement are fallen, block small outlet pipe, do not allow water from small water outlet by tegillum harden structure rotary motion
It flows out in hole.When king bolt hole is blocked by sundries, large cover will not be impacted by water, anti-jamming mechanism in clockwork spring restoring force and
Minor flaps rotate under by the impact force collective effect of water, and minor flaps leave small outlet pipe.Flow can pass through well lid shell machine later
Minor spiral hole on structure smoothly drains into water in well lid, since the effect of flow pushes minor flaps movement, in the band of minor flaps
Dynamic lower anti-jamming mechanism surrounds drive shaft rotary motion, to which with dynamic pressure large cover structure rotary motion, large cover tightly be pressed
On big outlet pipe.Since the direction of rotation in minor spiral hole is different from the direction of rotation in king bolt hole so that flow into minor spiral hole
The direction of flow changes before, to wash away the sundries on well lid shell at king bolt hole.Flow is set to reenter big spiral shell
Trepanning, so the water for flowing through king bolt hole is more, causes anti-jamming mechanism to send out since the aperture in king bolt boring ratio minor spiral hole is big
Raw reverse phase rotation, under the action of drive shaft, minor flaps is tightly pressed against at small water outlet pore, do not allow water from minor spiral hole
It flows through.To reach oneself cleaning tamper, the purpose for preventing well lid from blocking.
