Description

一种自锚桩式沉积物采样器
技术领域
本发明属于环境监测、环境治理及沉积物样本采集技术领域,涉及到水库等水深大、底质软的沉积物采集,特别涉及到水库柱状分层沉积物样品的采集。
背景技术
水体底部蓄积的沉积物污染已经成为当前水环境研究的热点。污染物质在其迁移转化过程和吸附释放过程,对水环境水生态产生不容忽视的影响。获得代表性的样品是这类问题研究的基础。
沉积物表层主要是软弱的水饱和淤泥,难以支撑采样设备,尤其是大型采样设备。而在重力作用下下层的沉积逐渐密实,使得底层沉积物的采集更加困难。当前的采集设备主要分为表层沉积物采集器和分层沉积物采集器。表层沉积物采样器常用的有抓斗式采泥器、箱式采泥器,对于浅滩、河口等地也可用铁锹直接获取。这些采集设备可以满足大多数情况下的表层沉积物样本采集。分层沉积物采集器主要是各种类型的柱状采泥器,可以分为重力式和振动式两种。重力式沉积物采集器依赖于采集器自重砸入水底的沉积物,从而实现沉积物样本分层采集,这类采集设备存在采样过程容易倾斜、自重较大、采样深度受限于自重等问题,对采样环境要求较高。振动式沉积物采集器是依靠频率振动'液化'沉积物实现分层采样,但该设备较大,目前主要在地质学采样中应用较多,在水域环境中很少应用。
显然,前述设备均在分层柱状沉积物采集中都不能完全解决设备复杂、重量大、采样效率低的问题。需要研发一种轻便、高效、适用性好的分层沉积物采样器。
发明内容
本发明要解决的技术问题是为了解决现有设备复杂、重量大、采样效率低的问题。提供一套轻便、高效、保真性好、人工操作的自锚桩式水库沉积物采样器。使其适用于水库等水深大、底质软的沉积物采集,尤其是水库柱状分层沉积物样品的采集。
本发明的技术方案是:
自锚桩式水库沉积物采样器,主要由锚架机构、采样导管、采样管机构、缆绳、配重构成。
锚架机构由顶部的固定板、底部的锚座、锚座上三个均布的定滑轮 A 、注水器、排水器、固定支架、定滑轮 B 、三个均布的卡钩、三个均布固定杆构成。固定板设有采样导管的预留孔和三个均布的穿绳孔,穿绳孔的位置与定滑轮 A 、定滑轮 B 、卡钩相对应,以便缆绳可以有效的连接整个仪器。锚座上设有三个均布的定滑轮 A 、注水器、排水器,并设有采样导管的预留孔和配重 5 的螺栓连接孔,底部设有环形支板。注水器的下部设有三个注水孔,注水孔没入锚座的环形支板,通过弹簧连接密封块,顶部有螺栓调节弹簧拉力,在采样过程中由于有弹簧的拉力使得密封块与管壁形成密封,当采样结束时,受到沉积物吸力密封块会下降至锚座下部,水便可通过注水孔注入锚座底部,从而释放锚座的吸力,轻便提出采集器。排水器与采样管机构的排水器相同,详见采样管机构的描述。固定支架设有三个缝以便采样导管的导轨通过,定滑轮 B 和卡钩安装在固定杆上。固定支架用以稳固整体结构。构件通过焊接、螺纹、角钢连接,形成锚架机构整体。
采样导管依次穿过固定板的预留孔、固定支架和锚座的预留孔,从而和锚架机构连接。采样导管设有三个均布的导轨,安装时要注意导轨与定滑轮 A 、定滑轮 B 、固定支架的预留孔相适应。采样导管底部内外均设有橡胶圈,外部的橡胶圈用以和锚座形成密封,内部的橡胶圈用以保证和采样管机构形成摩擦以保证采集器在下放时采样管机构不脱落。
采样管机构由上部外采样管,排水管、自平衡密封块、内样品管构成。外采样管顶部设有外螺纹,底部设有菊瓣式密封器,在上部设有三个均匀的小孔,用以和铁链连接。排水管顶部布有可拆卸的栅格,防止自平衡密封块溢出和大型物体进入采集器,排水管中部设有三个均布的排水口,内部设计成椭圆面和自平衡密封块契合形成密封,排水管下部设有内螺纹用以和外采样管的外螺纹连接。自平衡密封块采用轻型材料,通过调节下部的螺丝重量使其密度与水接近,但略大于水,容易在水动力作用下漂起,自平衡密封块重心在中心线底部,实现自动调节平衡保障和排水管契合,形成气密效果。排水管、自平衡密封块一起形成排水器,为整体结构。内样品管为亚克力有机玻璃管,配有相应的橡胶塞,待采样结束后保持样品。
缆绳用以连接整个设备,其分为三个部分,第一个部分三段铁链,从卡钩穿过定滑轮 A 至外采样管 3-1 小孔,第二部分为三个小段的缆绳,和卡钩上的铁链连接并穿过定滑轮 B ,从而与第一段铁链连接,第三部分为一段长的缆绳将第二部分的三段缆绳通过绳扣连接为整体的受力缆绳,改部分缆绳标有刻度,以掌握仪器下放深度。配重通过螺栓与锚座连接。
自锚桩式水库沉积物采样器通过将锚座的锚固力和自身重力(可通过配重调节)结合,在减少重量的同时还可提供稳定的采样环境,并通过两个定滑轮将拉力转为对外采样管的压力,形成类似打桩的采样方式。
本发明的效果和益处是相比于现有的沉积物采样设备效率低、操作复杂、重量大的不足,发明了人工既可操作、保真性好、轻便、高效适用于水库、湖泊、河流等水体的分层沉积物采集设备。

具体实施方式
以下结合技术方案和附图详细叙述本发明的具体实施方式。
自锚桩式水库沉积物采样器采集具体实施步骤如下:
步骤 1 :根据现场采样水深和计划采集沉积物的深度调节注水器的螺栓,设定密封块位置。将内样品管 3-4 套入外采样管 3-1 中,然后将排水管 3-2 上部的栅格打开,将自平衡密封块 3-3 放入排水管 3-2 ,并与外采样管 3-1 连接,形成采样管机构 3 ,将采样管机构 3 套入采样导管 2 ,采样管 3-1 受到采样导管 2 下部橡胶圈的摩擦力从而克服下落的重力。
步骤 2 :将第一个部分三段铁链,从卡钩 1-8 穿过定滑轮 A1-3 至外采样管 3-1 小孔,第二部分为三个小段的缆绳,和卡钩 1-8 上的铁链连接并穿过定滑轮 B1-7 ,从而与第一段铁链连接,第 3 部分为一段长的缆绳将第二部分的三段缆绳通过绳扣连接为整体的受力缆绳,该部分缆绳标有刻度,以掌握仪器下放深度,此时整个采集器的重力由第三部分缆绳承担,定滑轮 A1-3 和铁链部分不受力。之后安装配重 5 至锚座 1-2 。
步骤 3 :将采样器匀速下放至水底,此时,仪器接触到沉积物,在重力作用下,排水器 1-5 开始排水(与锚座部分类似),锚座 1-2 的环形支板锚入沉积物中,产生锚固力并与自重一起(可用配重调节)提供了稳定的采样条件,同时,仪器的重力由沉积物承担,铁链扣从卡钩 1-8 上脱落,此时, A1-3 和铁链开始受力,小幅度提拉缆绳,经定滑轮 A1-3 和定滑轮 B1-7 的转化,将向上的拉力转化为对外采样管 3-1 的压力,从而提供采样动力克服沉积物的阻力,通过小幅度提拉缆绳达到类似打桩的效果,实现分层沉积物采集。在样品采集过程中,自平衡密封块 3-3 受到水冲力作用被顶起、排水管 3-2 可通畅排水,隔绝了采样管内管压差,沉积物可顺利进入采样管。
步骤 4 :持续小幅度提拉缆绳,从而减少对沉积物样品的扰动使其在压力作用下,外采样管 1-3 沿着采样导管 2 继续采样,直至采样结束,此时,排水器 1-5 内的自平衡密封块在自身重力作用下逐渐下落与排水管底部形成气封,配合外采样管 3-1 下部的菊瓣式密封器,可保障样品不流失。采样结束后在提拉的过程中,沉积物施加在注水器 1-4 的密封块上的吸力持续增大,可将密封块吸入锚座 1-2 的环形支板,水从注水孔注入,释放沉积物吸力,减少设备上拉阻力。
步骤 5 :继续提拉缆绳将设备提出水面,配重 5 卸除,从下往上取出采样管机构 3 ,将排水管 3-2 拧开将、自平衡密封块 3-3 取出,外采样管 3-1 下部的菊瓣式密封器拧开,用配备的橡胶塞将内样品管 3-4 密封保存,至此单次采样结束,更换内采样管 3-4 重复步骤 1-5 便可继续采样。
