One end through 12 inlay card of through-hole in card slot 15.
On driving shaft 13 card slot 15 be shaped to flat recess (as shown in Figure 8), cross recess (as shown in Figure 10) or
Rice word slot (as shown in figure 12), as shown in Figure 7 and Figure 8, fixture block 16 is set as matching with flat recess accordingly in drive shaft 104
A block, and connected between driving shaft 13 and drive shaft 104 by flat recess and a block, corresponding well lid 1 is equipped with 01
Number；As shown in Figure 9 and Figure 10, fixture block 16 is set as the hydraulic steering gear adopting cross piece to match with cross recess accordingly in drive shaft 104, and main
It is connected between moving axis 13 and drive shaft 104 by cross recess and hydraulic steering gear adopting cross piece, corresponding well lid 1 is equipped with 02 number；Such as Figure 11 and
Shown in Figure 12, fixture block 16 is set as the rice block to match with rice word slot, and driving shaft 13 and driving accordingly in drive shaft 104
It is connected by rice word slot with rice block between axis 104, corresponding well lid 1 is equipped with 03 number, as shown in fig. 6, drive shaft 104 is carried on the back
One end from fixture block 16 connects handwheel 105, and handwheel 105 is in outside through-hole 12.
Implementation process: during installation, holding " u "-shaped bar 22, exerts a force to " u "-shaped bar 22, makes dovetails 181 in dovetail groove
Sliding, spring 21 are in compressive state in 182, and the first filter screen 171 and the second filter screen 172 are close to each other, at this time by first
The area of the filtration members 17 of filter screen 171 and the second filter screen 172 composition becomes smaller, and filtration members 17 are passed through ring baffle 3, were made
Filter part 17 is in position corresponding with annular groove 20, slowly reduces the power applied to " u "-shaped bar 22, spring 21 is by compressive state
Slowly be restored to nature, the first filter screen 171 and the second filter screen 172 mutually away from movement, the areas of filtration members 17 by
Gradual change is big, when connecting rod 19 is in annular groove 20, unclamps " u "-shaped bar 22, filtration members 17 are mounted on 2 inner wall of walling crib at this time
On.
After filtration members 17 are mounted on 2 inner wall of walling crib, well lid 1 is covered into the ring edge position in walling crib 2, in installation well lid 1
In the process, the gag lever post 9 on well lid 1 enters L shape undercut 8 perpendicular to the part on ground, according to card slot 15 on driving shaft 13
Shape, selection passes through well lid 1 with the drive shaft 104 of fixture block 16 to match with card slot 15, by one end with fixture block 16
On through-hole 12 rotate handwheel 105 by 16 inlay card of fixture block in card slot 15, the rotation of handwheel 105 drives drive shaft 104 to rotate,
Drive shaft 104 drives drive bevel gear 101 to rotate by driving shaft 13, what the rotation drive of drive bevel gear 101 engaged
First driven wheel of differential 102 and the rotation of the second driven wheel of differential 103, driven shaft 14 is with the first driven wheel of differential 102 and second
The rotation of driven wheel of differential 103 and rotate, the rotation of driven shaft 14 drives the rotation of the first ring gear 4, mistake of first ring gear 4 in rotation
Cheng Zhong, the gear 6 engaged rotate, and the rotation of gear 6 is to drive the second ring gear 7 engaged rotation, the second ring gear 7
Rotation drive well lid 1 to rotate, the rotation of well lid 1 drives gag lever post 9 to rotate, and gag lever post 9 is out of L shape undercut 8 perpendicular to ground
The part on ground is parallel in the partial turn in face to L shape undercut 8, L shape undercut 8 is to gag lever post 9 in vertical direction at this time
On limited, well lid 1 and walling crib 2 are linked together, well lid 1 is avoided to be detached from from walling crib 2 in discontinuity, by well
Lid 1 lifts drive shaft 104 after 2 upper limit of walling crib, through handwheel 105, separates drive shaft 104 with driving shaft 13, will drive
Moving axis 104 takes out out of walling crib 2, and the through-hole 12 on well lid 1 is exposed, and someone is on the one hand avoided to pass through rotation handwheel 105
Well lid 1 is disassembled from walling crib 2, causes well lid 1 stolen, it is on the other hand convenient to flow into rainwater by through-hole 12 in the rainy day
In well, achieve the effect that draining, by drive shaft 104 take out after, according between drive shaft 104 and driving shaft 13 card slot 15 with
The shape of fixture block 16 writes down corresponding number, conveniently knows well lid 1 according to the number on well lid 1 when needing to dismantle well lid 1 later
The shape of card slot 15 is dismantled well lid 1 directly using the drive shaft 104 for having respective shapes fixture block 16 on driving shaft 13 below
Get off, saves the plenty of time.It improves work efficiency.
If when taking out filtration members 17 out of walling crib 2, staff looks for according to the number on well lid 1 because of need of work
The drive shaft 104 for having fixture block 16 corresponding with number out, by the handwheel 105 in drive shaft 104 by drive shaft 104 with card
One end of block 16 passes through the through-hole 12 on well lid 1, makes card slot 15 of 16 inlay card of fixture block on driving shaft 13 in drive shaft 104
It is interior, handwheel 105 is rotated, the rotation direction of handwheel 105 is with rotation direction when installation well lid 1 on the contrary, drive shaft 104 passes through at this time
Driving shaft 13 drives drive bevel gear 101 to rotate, and the rotation of drive bevel gear 101 drives the first driven wheel of differential engaged
102 and second driven wheel of differential 103 rotate, thus drive on the first driven wheel of differential 102 and the second driven wheel of differential 103 from
Moving axis 14 rotates, and the rotation of driven shaft 14 drives the rotation of the first ring gear 4, and the rotation of the first ring gear 4 drives the gear 6 engaged
Rotation, in rotation, the second ring gear 7 engaged rotates, the rotation band of the second ring gear 7 gear 6 with the rotation of gear 6
Dynamic well lid 1 rotates, and during well lid 1 rotates, the gag lever post 9 on well lid 1 is parallel to the part on ground from L shape undercut 8
L shape undercut 8 is moved to perpendicular to the part on ground, gag lever post 9 no longer limits well lid 1 and walling crib 2, by well lid 1 from walling crib 2
On take off, then will be disassembled from 2 inner wall of walling crib with the rotation axis 5 of gear 6, the first ring gear 4 taken out of walling crib 2
Out, it exerts a force to " u "-shaped bar 22, keeps the first filter screen 171 and the second filter screen 172 close to each other, connecting rod 19 detaches annular
Slot 20 takes out the filtration members 17 that the first filter screen 171 and the second filter screen 172 form out of walling crib 2.
The above embodiments are only explanation of the invention, are not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
