Description
Technical field
The utility model relates to a kind of water environment sediment sampler, is specifically for the sedimental grab type sediment sampler in lake, river.
Background technology
Sediment anyly by the particulate of fluid flows movement, and can finally become one deck solia particle under water or other liquid base layer.The sediment of water body not only can retain the natural geological information in basin, and can reflect the impact of artificial action on environment.In recent years, China's water environmental problems has become the hot issue that people pay close attention to, and to the research of water environment pollution aspect also progressively deeply, therefore, also becomes extremely urgent major issue to the monitoring of water environment, investigation.Particularly heavy metal element has the characteristic that can not be biodegradable, once enter water body and sediment, by food chain enrichment in vivo, finally enters human body, causes the such as disease such as minamata disease, itai-itai, serious harm health.The content distribution of Heavy Metal In Sediments both can reflect pollution situation, contamination characteristics and potential risk that all basins are long-term, also can follow the trail of possible source of heavy metal pollution, evaluated human activity to the contribution of Mixing Coefficient in Rectangular Channels.Therefore, by can fully understand kind and the changes in distribution feature of waters ambient contamination thing to Sediments research, be the technical way of water body environment monitoring.
At present, sediment sampler is as the important tool of monitoring water environment, and its science, operability and cost performance are most important to bed mud sample collection.People, to water body, when sediment investigation is carried out in such as river, lake, reservoir or ocean, need the sediment gathering water bottom, and in this process, bottom sampler usually can be used to complete sampling.If do not reach sampling object because bottom sampler can not gather the various reasons such as sample size in sediment, the sediment that collects is few, just must again carry out sediment collecting work, so the efficiency of bottom sampler sampling drastically influence progress and the quality of the investigation of relevant water body environment.
At present, China lacks the standards and norms for bed mud sample collection instrument, and the sampling instrument development research particularly for bed mud sample is less.Sediment sampler comparatively is widely used to mainly contain peat auger sampling thief, grab type sampling thief and piston type column shaped deposit sampling instrument.Peat drills through sampling thief can run into some problems in use procedure, and as tight in required sampling location, single sampling amount is few, must complete sampling work by multi collect; And traditional grab type sampling thief exists the occlusion of grab bucket jaw not sternly, lifting process has omission, causes sample to run off thereupon; The design of piston type columnar sampler is complicated, carries inconvenience, and frequent dismounting sampling pipe is wanted in use procedure, uses inconvenience, and above-mentioned reason often makes the sediment collected not reach index request and sampling object, causes and samples unsuccessfully.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simplicity of design, the lake grab type sediment sampler that with low cost, easy to carry, simple to operate, sampling efficiency is high.
The utility model solves the problems of the technologies described above taked technical scheme: a kind of lake grab type sediment sampler, comprises traction rope, wire rope, wire rope pulley, adopts mud grab bucket, grab bucket carrying handle and strut of grabbing bucket; Described mud grab bucket of adopting comprises left grab bucket and right grab bucket, and the openend top of left grab bucket and right grab bucket is hinged, makes left grab bucket relative with right grab bucket opening and can close tight; Grab bucket carrying handle comprises left carrying handle and right carrying handle, and left carrying handle one end is connected with right grab bucket blind end top, and right carrying handle one end is connected with left grab bucket blind end top, and the left carrying handle other end is connected with wire rope by wire rope pulley with the right carrying handle other end; Be connected with traction rope after steel wire penetrating wire rope pulley; Described grab bucket strut one end is connected with left grab bucket blind end top, the other end is provided with opening up hook, right grab bucket blind end top is provided with and links up with corresponding link, hook coordinates with link can make left grab bucket and right grab bucket keep open state, after adopting the mud grab bucket tactile end, hook is deviate from from link, and left grab bucket and right grab bucket are closed.
Described left grab bucket and right grab bucket top are equipped with weightening finish block, and the side of blind end is also provided with ventilative spillway hole.
Described left grab bucket and right grab bucket are two structures and 1/4th measure-alike hollow cylinders.
Described wire rope, adopt mud grab bucket, grab bucket carrying handle, grab bucket strut, link and weightening finish block all adopt stainless steel material to make.
The utility model has simplicity of design, with low cost, easy to carry, the advantage that simple to operate and sampling efficiency is high, during use, the hook of grab bucket strut is connected with link, ensure that left grab bucket and right grab bucket are in open state before the tactile end, it is slowly put into water, can overflow from ventilative spillway hole entering air in water process, after adopting mud grab bucket and touching the end, due to grab bucket strut hook upwards, it is made to adopt after the end is touched in mud grab bucket and can automatically unclamp, upwards pulling traction rope, the mud grab bucket of adopting being welded with weightening finish block is closed up and rises under self gravitation effect, be closed in the Sediments adopted in mud grab bucket and be suggested the water surface thereupon.In lifting process, adopt mud grab bucket for two and close tight, can not occur to leak mud phenomenon, part water also can overflow from ventilative spillway hole, alleviates the weight of whole device, and whole operating process is more prone to.The utility model adopts stainless steel to make, and can avoid getting rusty, increase the service life.
