Description

The low disturbance cutting type sampling of sludge reservoir cutter head
technical field:
The utility model relates to a kind of critical component of underwater sampling equipment, relates in particular to the low disturbance cutting type sampling of a kind of sludge reservoir cutter head.
background technology:
At present, obtain the sedimental sampler of underwater sludge matter and have the sampling equipments such as grab type, box, freezing type, gravity type.Mainly there is two large problems in these sampler: during sampling to the perturbed problem of sample and when sampling sample leakage problem.Grab simpler application at present river course sampling is comparatively extensive, but it exists that sampling depth is shallow, success ratio is low and the shortcoming such as sample perturbation is large, and its utilization scope has been subject to very big restriction, continuous progress along with technology, TV grab bucket deep earth sampling device and box corer on ocean, have been there is, underwater television camera is housed in the former grab bucket, by the watch-dog on ship, find and control grab bucket after target and sample, Cheng Zhenbo, Wu Yonghua etc. write. and " grab bucket of deep-sea Novel sampling instrument-TV and using method " [J]. coastal engineering, 2011,30 (1): 51-54, the latter's sampling cabinet is tetragonal body, rely on gravity make sampling cabinet insert in marine bottom sediment and drive shovel arm to rotate with collected specimens, Geng Xueqiao, the current situation and development trend of Deng Suozhu“ China ocean sampling equipment creeps " geology equipment, 2009,10 (4): 11-16, these two kinds of sampler operating depths are larger, but larger to sample disturbance, freezing formula sampler sampling quality is higher, its principle of work is at the in-built refrigerating fulid of sampling head, during operation, sample is frozen in inner cavity chamber, thereby obtain the sedimental column original state sample of low disturbance and interfacial water, Li Guomin, Liu Baolin, Deng show " structural design of Icing Sampler " [J]. mineral exploration engineering, 2003, (Suppl.): 179-182. and Guo Wei, Sun Youhong, Chen Chen shows " design of FPCS type gas hydrate hole-bottom frozen pressure keeping sampler " [J]. machine design and manufacture, 2011, (1): 24-26., but its complicated operation, equipment is huge, sampling cost is higher, gravity type sampler principle is that sampler obtains cylindrical sample at the self gravitation effect injection bottom, and sampling thickness depends on substrate hardness and device structure shape and counterweight, existing utilization aspect oceanic sediment sampling.In general, adopting gravity type sampler is the at present comprehensive higher technological means of sexual valence.
To this, Yellow River In Recent Years Institute of Hydro-Technical Research uses for reference deep-sea drift fidelity sampling principle, transform and develop the low disturbance column deep water reservoir area sampling equipment based on gravity type piston technology: Yang Yong, Zhang Qingxia, Chen Hao, Zheng Jun shows " the low disturbance sampling equipment of huge reservoir design and functions is analyzed [C] ". the 5th international symposium, the Yellow River paper, 2012.09; Yang Yong, Zheng Jun, Chen Hao shows " Machine Design of the low disturbance sampler of huge reservoir ". Advances In Science And Technology of Water Resources, 2012,32 (S2): 18-19: sampler internal diameter 90mm, the pipe range 10m of design, be mainly partly comprised of guiding device, flip flop equipment, sampler etc.When sampler is transferred to while also having a segment distance apart from river bed, counterweight block first touches riverbed, lever out of trim, the action of triggering releasing mechanism, stopple coupon subject freedom falls, under the effect of deadweight and inertia, insert in drift, stopple coupon lower end adopts pawl spring structure to cut off and hold drift.The suction producing due to piston is offset the friction force balance between stopple coupon inwall and sample, like this, has just been full of the alluvial sample of low disturbance in stopple coupon.The deep water sampling preliminary test of carrying out in Reservoir Area of Sanmenxia shows, for hard channel aggradation silt, reaches stable unit dry weight, can obtain cylindrical sample more than thickness 3m; But for the soft shoal materials layer in the Yellow River, gravity type sampling piston device is deposited problem both ways: the 1) interference problem of pawl spring device.For the sample taking out is not come off in lifting process, often in stopple coupon bottom, increase pawl spring to support sediment.If shale is too soft, limited to the thrust of pawl spring diaphragm seal, pawl spring cannot guarantee in open configuration, can cause larger disturbance to sample.Therefore, necessary physical construction reasonable in design, makes to grab spring and when lower bundle, keeps open configuration, and when promoting sample, closed in time, complete sampling action.2) leakage problem.Between pawl spring reed and between pawl spring and bushing pipe, have gap, soft silt is relatively more easily revealed from gap, and because reservoir area ship is generally relatively little, sampler is more prone to produce and swings, spins, and these actions all can aggravate the loss of sample.It is to have the serrate cutting ring of several side grooves and reed pipe to be slidably matched that Chinese patent CN2083189 discloses a kind of " sampler of underwater undisturbed silt " its basic structure, in pipe, there are several reeds to play support studies on sediment, reed pipe, two pipes that narrow, spoir pipe, center tap, weight sleeve pipe, top connection is thread connection successively, ball valve is arranged at center tap bottom, the two inside pipe wall dress soil sample tubes that narrow, although this sampler convenient disassembly, but also have the following disadvantages: 1, need to use drilling rod first to stretch under water, if the depth of water is larger, especially the depth of water is over 60 meters, need to handle jointed rod, increase the expense of drilling rod and the time of jointed rod bought, cost is higher, if 2 depth of waters are larger, hammering work is wasted time and energy, and by hammering, samples, and sample is produced to larger disturbance, is difficult to guarantee sample original state, 3, reed inwardly shrinks and firmly scratches sample all the time, and sample surfaces is subject to disturbance larger, is especially difficult to obtain rarer soft sample, 4, take out sample in iron sheet barrel, cannot with the naked eye distinguish sample layering, color and proterties, be difficult for cutting chromatographic analysis sample.
summary of the invention:
In order to solve, obtain the sedimental low disturbed sample difficult problem of fine sediment of reservoir matter, the utility model object is just to provide the low disturbance cutting type of a kind of sludge reservoir reasonable in design, simple in structure, easy to operate and that sampling efficiency is high sampling cutter head, thereby provides technical support for accurate analysis sludge reservoir physicochemical characteristics.
The technical solution of the utility model realizes in the following manner:
