Abstract
The invention discloses a sampling soft bag sealing mechanism by a plurality of sheets of coiled reeds. According to the technical scheme disclosed by the invention, a sealing resilient sheet is arranged adjacently to a soft bag along the peripheral direction; the coiled reeds are arranged on the upper part of the sealing resilient sheet and sealing sheets are arranged on the lower part of the sealing resilient sheet; when being in a gap between a coring drilling rod and a retaining core barrel, the sealing resilient sheet is strengthened by a binding belt; the coiled direction of the original coiled state of the coiled reeds on the sealing resilient sheet faces the axis direction of the retaining core barrel; the sealing sheets tend to be horizontal and are close to the axis of the retaining core barrel when being in the retaining core barrel. According to the sampling soft bag sealing mechanism, after the sealing resilient sheet enters the inner part of the retaining core barrel, the coiled reeds recover the original coiled state and the sealing sheets tend to be horizontal and are close to the axis of the retaining core barrel so as to drive a soft bag part in contact with the sealing sheets to be close to the axis of the retaining core barrel, so that the sealing work is realized. The sampling soft bag sealing mechanism adopts two-grade sealing and can realize ordered sealing so as to guarantee the sealing reliability. The sampling soft bag sealing mechanism is reasonable in structural design, simple and convenient to operate and good in sealing performance.
Description
technical field:
The present invention relates to the enclosed mechanism of lunar soil harvester under a kind of space flight state of weightlessness, be specifically related to multi-disc wind spring sheet and sample soft bag sealer structure.
background technology:
Aeronautical and space technology is that the mankind explore natural forward position engineering, and walking space-ward has become the requisite sign of science and technology power, and in aerospace system, each link is extremely important, how at the moonscape of low gravitation, to collect and to drill through a lunar soil large technical barrier especially.As shown in Figure 1, the up-to-date lunar soil sampling apparatus that drills through consists of coring drill rod 1, maintenance core barrel 2 and soft bag 5, keep core barrel 2 to be located in coring drill rod 1, under off working state, soft bag 5 is fixed on soft bag joint 3 and by the traction rope 8 on it and drives in coring drill rod 1 and the Nei，Qi top, gap that keeps core barrel 2; During work, after coring drill rod 1 decline puts in place, soft bag 5 is drawn in and is kept in core barrel 2 by traction rope 8, thereby dress is got lunar soil.While using this kind of mode to collect sampling, unique technical bottleneck is exactly the sealing problem of collecting soft bag after sampling, this is to be related to the key step that can collection work complete smoothly, still needs further to explore experiment with regard to this problem, finds out more suitably technical scheme.
summary of the invention:
The object of this invention is to provide multi-disc wind spring sheet and sample soft bag sealer structure, it can seal the sampling apparatus that drills through under moon low-gravity environment, its reasonable in design, simple and efficient to handle, good airproof performance.
Multi-disc wind spring sheet of the present invention samples soft bag sealer structure, for solving the technical scheme that its technical matters adopts, be: this multi-disc wind spring sheet samples soft bag sealer structure, it is characterized in that: soft bag is circumferentially with sealing shell fragment near end edge, the top of described sealing shell fragment is wind spring sheet, bottom is cap liner, sealing shell fragment is stretched straight by restraining at coring drill rod with while keeping in the gap of core barrel, the direction of crispaturaing of the original crimped configuration of volume pornographic movie on it is towards the axis direction that keeps core barrel, cap liner on it is tending towards level and draws close to the axle center of maintenance core barrel when keeping core barrel inner.
Preferably, described sealing shell fragment is fixed in the interlayer of soft bag by the cap liner on it.
Preferably, the end of described soft bag is provided with two-stage sealing shell fragment.
The invention has the beneficial effects as follows: this multi-disc wind spring sheet samples soft bag sealer structure, mainly by sealing shell fragment, carry out sealing operation, when it keeps in core barrel along with soft bag enters, volume pornographic movie on it is by turning in flat to the original crimped configuration that keeps core barrel inside, to drive the port of soft bag to keeping the axle center of core barrel to draw close, the cap liner of meanwhile rolling up pornographic movie below is tending towards level and draws close to the axle center of maintenance core barrel, the Ruan Dai position that drive is in contact with it is also tending towards level and draws close to the axle center of maintenance core barrel, and sealing shell fragment is when recovering ortho states, by the port radial compression of soft bag to fold state, the space that its fold surrounds each cap liner is filled up, thereby realize sealing operation.And in the present invention, adopt two-stage sealing, can realize gradually order sealing, guarantee the reliability of sealing.Reasonable in design of the present invention, simple and efficient to handle, good airproof performance.
accompanying drawing explanation:
Fig. 1 is the working state figure before the present invention seals.
Fig. 2 is the working state figure of the present invention while sealing.
Fig. 3 is that sealing shell fragment of the present invention is located at the partial structurtes schematic diagram on soft bag.
Structural representation when Fig. 4 is sealing shell fragment sealing of the present invention.
embodiment:
With reference to each accompanying drawing, this multi-disc wind spring sheet samples soft bag sealer structure, it is characterized in that: soft bag 5 is circumferentially with sealing shell fragment near end edge, the top of described sealing shell fragment is that wind spring sheet 9, bottom are cap liner 10, sealing shell fragment is stretched straight by restraining at coring drill rod 1 with while keeping in the gap of core barrel 2, the direction of crispaturaing of the volume pornographic movie 9 original crimped configuration on it is towards keeping the axis direction of core barrel 2, cap liner 10 on it to be tending towards level when keeping core barrel 2 inner and to keeping the axle center of core barrel 2 to draw close.Sealing shell fragment is made in the interlayer of soft bag 5 by the cap liner 10 on it.The end of soft bag 5 is provided with two-stage sealing shell fragment.
Before lower brill, soft bag 5 is coated on the outer wall that keeps core barrel 2, and the sealing shell fragment of soft bag 5 ends is under the constraint of restraining and maintenance core barrel 2, in flat; During lower boring, soft bag 5 one-level sealings are pulled rope 8 and are pulled into maintenance core barrel 2 inside, when one-level sealing shell fragment moves to soft bag 5 port that keeps core barrel 2 lower ends, restraining comes off, volume pornographic movie 9 on it turns in flexing to keeping core barrel 2 inside under self elastic reaction, release energy and return to original crimped configuration, drive cap liner 10 to draw close and be tending towards level to the axle center that keeps core barrel 2, cap liner 10 drives the position of the soft bag 2 being in contact with it to be also tending towards level and to keeping the axle center of core barrel 2 to draw close, completes one-level sealing.Along with soft bag 5 continues to the movement keeping in core barrel 2, secondary sealing shell fragment finally completes the secondary sealing to soft bag 5 equally in this way.In sealing processes at different levels, sealing shell fragment when recovering ortho states by the port radial compression of soft bag 2 to fold state, the space that its fold surrounds each cap liner 10 is filled up, thereby realizes sealing operation.This embodiment is simple and efficient to handle, time saving and energy saving, good airproof performance.
