Specific implementation mode
Further detailed description is done to the present invention below in conjunction with the accompanying drawings:
As shown in Figure 1, 2, 3, a kind of series connection compression packer of the invention, the annular being arranged between guide cylinder 1 and piling bar 2
In space, piling bar 2 is through in guide cylinder 1, if including the dried layer annular utricule 4 that is superimposed and links together up and down, top layer
4 top of annular utricule is connected with the top board 5 of annular, and top board 5 is connected with the sealing tablet 6 of annular, seals the outer circle of tablet 6
It is integrally extended with the sealing riser 7 that can slide up and down week upwards along the inner wall of guide cylinder 1, seals and set between riser 7 and guide cylinder 1
It is equipped with sealing ring 8,4 bottom of undermost annular utricule is connected with lower pallet 10, and lower pallet 10 is fixed on the inner wall of guide cylinder 1
On.Lower pallet 10 is circular ring shape, and 10 lower section of lower pallet is connected with the support tablet 12 of circular ring shape, supports the excircle edge of tablet 12
The inner wall of guide cylinder 1 is integrally extended with downwards fixed plate 13, and the fixed plate 13 is connected with the inner wall of guide cylinder 1 by bolt
It connects, the fixed plate 13 and support tablet are connected with diagonal support 14 between 12 bottom.It is compressed as mobile on annular air-pocket top
End, annular air-pocket bottom are fixed, and can realize downward compression.
It is provided with intermediate bulkhead 15 between two layers neighbouring of annular utricule 4, spring base is provided on intermediate bulkhead 15
16, the compressed spring 9 through annular utricule 4, pressure are connected between the spring base 16 on neighbouring two layers of intermediate bulkhead 15
Force transmission contact part of the contracting spring 9 as internal compression.Through-hole 17 is provided on spring base 16, through-hole 17 is connected to neighbouring
Two layers of annular utricule 4.The series connection that each annular air-pocket inner chamber body is realized between annular air-pocket, ensures the consistency of internal pressure, and
Inside increases compressed spring 9, realizes that the annular air-pocket under original state props up state, whole each annular air-pocket can be by upper
The weight difference of portion's ballast cement mortar realizes compression of the gravity to utricule, as shown in Figure 4.
Disengaging gas-liquid mouth 11 is provided on lower pallet 10,11 upper end of disengaging gas-liquid mouth is connected with annular air-pocket, and into
Go out 11 lower end of gas-liquid mouth and be connected with the connector with valve, gas or liquid can be accessed by external pipe connector etc., to increase
Big annular 4 internal pressure of utricule, can thus improve the contact among 2 outer wall of annular utricule 4 and piling bar, improve leakproofness
Energy.Annular utricule 4 uses rubber material, if the side wall of annular utricule 4 is bonded by dried layer rubber layer, in every layer of rubber layer
It is embedded with polyamide skeleton line, enhances compressive resistance.It is provided on 1 inner wall of guide cylinder of 6 top of sealing riser 7 and sealing tablet
Several guide plates 3 extended in a radial direction, 3 top of guide plate are provided with high outside and low outside bevel edge.
Its course of work:
Mode one, under normal condition it is whole in the seawater, when cement mortar is injected on top, due to the weight between cement mortar and seawater
Amount is poor, causes 6 top of sealing tablet that can accumulate more and more cement mortars, sealing riser 7 and sealing tablet 6 are along guide cylinder 1
Wall slide downward, to the annular utricule 4 that gradually reduces, the contact between utricule and piling bar 2 is realized in 4 compressive deformation of annular utricule
Sealing, grout pouring amount is more, and sealing effect is more apparent;
Mode two can pass through the disengaging gas-liquid of 4 lower part of annular utricule when needing larger sealed pressure in filling process
Annular 4 inner airs of utricule of mouthfuls 11 extractions or liquid, annular utricule 4 deform larger, and the contact surface of formation is larger, with upper water
The increase of mud weight and the sealing for realizing bigger pressure.
The above is only the preferred embodiment of this patent, it is noted that for the ordinary skill people of the art
For member, under the premise of not departing from the art of this patent principle, several improvement and replacement can also be made, these improve and replace
Also it should be regarded as the protection domain of this patent.
