Abstract
This invention discloses a self-adjusting sealing cap for deep sea pipe sampler, whose composition board is made of circular rubber layer and PVC material base and whose center is placed a bulb probe rotating freely with bolt and locked by bottle capping. The sealing cap can seal effectively the end of pipe sampler due to bulb probe freely rotating around center bolt, arc movement trace in the process of sealing and the compressed deformation generated by high pressure of sampler in deep sea. The invention is suitable for trace sealing with non-vertical direction of two ends of connecting pipe and compressed deformation sealing with non-definite quantity of connecting pipe.
Description
Technical field
The present invention relates to abyssal sediment sampling technique field, be specifically related to the seal closure of stopple coupon in a kind of sampler.
Background technology
In the marine bottom sediment sampling process, wherein a key technology is that the device of carrying out sampling is implemented effectively to seal, pipe sampler is the most reliable and effective means of carrying out the marine bottom sediment sampling, but, if the stopple coupon upper end mouth of pipe effectively can not be sealed, in the time of will causing stopple coupon to be extracted from sediment, the landing from stopple coupon of sediment mud sample makes the sampling failure.In addition, the stopple coupon bottom nozzle is not tight as if sealing, and is rising to from the deep-sea the process of deck, with the deadweight reason of mud sample in seawater scouring and the stopple coupon, can produce sample yet and run off.
Stopple coupon sealing tech research needs to consider two kinds of restraining factors, the one, what stopple coupon must both ends open when sampling, could allow the mud sample enter in the pipe, and the process of sealing is an arching trajectory, can not adopt rigid seal, must flexibility seal.The 2nd, stopple coupon can be out of shape under the high pressure of deep-sea, and the distortion size is relevant with the depth of water, and this is the variable that can't know in actual use, and deformation also can cause sealing not tight.
Summary of the invention
Seal and mend the compression set of tasting stopple coupon for what solve the stopple coupon arching trajectory, invent and a kind ofly to be suitable for using in the ocean, can carry out self-regulating seal closure to the tubular structure stopple coupon, the tubulose stopple coupon is sealed tightly, improve the sampling success ratio of sediment mud sample.
To achieve these goals, the technical solution used in the present invention is: a kind of self-regulation seal closure, comprise the capping base plate, rubber slab, bulb connects double-screw bolt and gland, bulb connects double-screw bolt and comprises bulb and screw rod, be provided with spherical pore at the capping base plate interior, spherical pore communicates with the external world by the cylindrical hole that is located at its outside, in described cylindrical hole, be provided with the gland corresponding with it, the gland middle part is provided with movable groove, and the bulb of described bulb coupling bolt is located in the described spherical pore, and the screw rod of bulb coupling bolt passes the movable groove of described gland, described movable groove outside surface to the junction of bulb coupling bolt bulb and screw rod is a circular platform type, described rubber slab is fixed on capping base plate bottom surface, because the end cap middle part is provided with movable groove, described capping base plate just can rotate in set angle around the bulb coupling bolt by movable groove.
As a preferred embodiment of the present invention, described capping base plate bottom is cylindrical, and top is truncated cone-shaped.
As a preferred embodiment of the present invention, described cylindrical hole is threaded with gland.
As a kind of improvement of the present invention, described gland upper surface is provided with and helps tankage.
As a kind of improvement of the present invention, described movable groove inboard is the same footpath sphere corresponding with spherical pore.
Estimate barrier for machineries such as corrosion, adhesion inertia take place in seawater in minimizing, capping base plate and sphere gland adopt the PVC material, and the bulb connecting screw rod adopts stainless steel to make.
The sealing mode that the present invention forms by bulb connecting screw rod and capping base plate, can realize stopple coupon effectively being sealed with the arcuate movement track, reason is that such seals is self-regulating, the self-regulation seal closure can remedy simultaneously the closed intensity that seals that the compression set of stopple coupon under the condition of deep-sea cause, tight stopple coupon seals, bring basic assurance for finishing the sampling of plug-in type sediment, also improved the power that is sampled into of abyssal sediment sampling simultaneously.
