Description

水下砂石清理装置 技术领域
本发明涉及施工用具技术领域，特别涉及一种水下砂石清理装置。
背景技术
在江河湖泊的河道内，特别是在修建大坝、桥梁等工程后通常存在砂石淤堵河道的情况，如果不对河道内淤堵的砂石及时进行清理，不仅会影响了河道的通航和泄洪能力，还会对河道的生态功能产生了一定的破坏。目前一般采用清淤装置对砂石进行清理，而对砂石清理前，首先需要通过运输船将清淤装置运输到安装点，再将清淤装置与运输船上的下放装置进行连接，随后通过下放装置将清淤装置下放到水里对砂石进行搅碎收集并通过输送管道输送到运输船上或放置点。现有的清淤装置一般包括固定机构、收集机构和清淤绞头，清淤绞头固定安装在固定机构上，当固定机构到达河道底部时，通过清淤绞头对砂石进行搅碎和收集，因为清淤绞头相对于固定机构无法发生位移，在清理砂石时，需要一层一层的搅碎收集砂石，对每一层砂石进行搅碎收集的过程中，需要一边水平移动清淤装置一边进行搅碎收集砂石，存在效率低、工作稳定性差、难以操控等问题。
发明内容
本发明要解决的技术问题是克服现有技术存在的不足，提供一种搅碎能力好，效率高的水下砂石清理装置。
为解决上述技术问题，本发明提出的技术方案为一种水下砂石清理装置，包括机架、安装在所述机架上的一个以上用于搅碎砂石的绞吸头以及与各绞吸头相连用于收集运输被绞碎后的砂石的收集运输机构，各绞吸头以相对于机架上下运动的方式安装设置在机架上。
作为上述技术方案的进一步改进：
所述机架上安装有一上下滑动设置的升降座，各绞吸头安装在所述升降座上。
所述水下砂石清理装置还包括用于弹性托持升降座的可更换弹性组件。
所述升降座通过导向组件上下滑动设置在机架上，所述导向组件包括多根固接于机架上的滑杆，所述升降座上对应各滑杆均设有一与该滑杆上下滑动配合的滑套。
所述弹性组件包括与滑杆数量一致且一一对应的伸缩弹簧，各伸缩弹簧套设在对应滑杆外部，且各伸缩弹簧的两端分别对应与机架和滑套相抵。
所述升降座连接有用于供牵拉绳连接以提升升降座的连接部。
所述收集运输机构包括一个以上输送泵，每个输送泵至少连接一个所述绞吸头；所述输送泵安装在升降座上。
所述输送泵的下方设有呈喇叭状的收集口，所述收集口供被搅碎后的砂石进入所述输送 泵内。
所述机架设有多个向下延伸用于插入砂石中以将机架支撑固定在砂石上方的固定桩。
所述机架上设有一个以上用于连接起吊设备的吊耳和一个以上用于驱动机架在水下移动的螺旋桨。
与现有技术相比，本发明的有益效果为：
在本发明方案中，首先利用绳索将水下砂石清理装置下放到水里的清理点，直至机架达到河道底部，接着绞吸头对砂石进行绞吸，由于绞吸头能沿机架上下移动，当绞吸头处的砂石被搅碎和收集后，此时机架保持不动，绞吸头能继续沿机架向下移动继续对更深处的砂石进行搅碎和收集。相对于技术，这种水下砂石清理装置能在较硬地质的环境下进行作业，且容易操作，可在竖直方向上移动绞吸头对更深处的砂石进行搅碎和收集，不需要频繁的在水平方向上移动，提高了效率，具有优良的稳定性。

具体实施方式
为了便于理解本发明，下文将结合说明书附图和较佳的实施例对本发明做更全面、细致地描述，但本发明的保护范围并不限于以下具体实施例。
除非另有定义，下文中所使用的所有专业术语与本领域技术人员通常理解含义相同。本文中所使用的专业术语只是为了描述具体实施例的目的，并不是旨在限制本发明的保护范围。
如图1至图4所示，本实施例的水下砂石清理装置，包括机架1、安装在机架1上的一 个以上用于搅碎砂石的绞吸头4以及与各绞吸头4相连用于收集运输被绞碎后的砂石的收集运输机构3，各绞吸头4以相对于机架1上下运动的方式安装设置在机架1上。对水里的砂石进行清理时，首先将整个清理装置搬运到运输船上，接着利用运输船将该清理装置运到清理点附近，紧接着利用吊升装置将整个清理装置下放到的清理点，直至机架1到达河道底部，此时，驱动各绞吸头4和收集运输机构3同时进行运转，使砂石被搅碎吸取后立刻通过收集运输机构3进行输送，随着砂石被不断的被搅碎和收集，绞吸头4所处的平面逐渐低于机架1所处的平面，由于绞吸头4可相对于机架1上下运动，所以绞吸头4在自身重力的作用下逐渐向下运动，对位于更深处的砂石进行搅碎收集，如此反复，直至绞吸头4相对于机架1无法进行移动。相对于现有技术，这种水下砂石清理装置能在较硬地质的环境下进行作业，且容易操作，可在竖直方向上移动绞吸头4对砂石进行搅碎和收集，不需要频繁的在水平方向上移动，提高了效率，具有优良的稳定性。
本实施例中，机架1上安装有一上下滑动设置的升降座2，各绞吸头4安装在升降座2上。将升降座2和机架1之间以滑动的形式进行设置，通过升降座2带动绞吸头4相对于机架1上下移动，结构简单，稳定性好。
本实施例中，水下砂石清理装置还包括用于弹性托持升降座2的可更换弹性组件。当升降座2沿机架1向下滑动时，升降座2对该弹性组件进行压缩，通过更换该弹性组件可调节绞吸头4每次作业的深度，实现对不同硬度的砂石的搅碎，扩大了该清理装置的使用范围。
本实施例中，升降座2通过导向组件上下滑动设置在机架1上，导向组件包括多根固接于机架1上的滑杆21，升降座2上对应各滑杆21均设有一与该滑杆21上下滑动配合的滑套22。通过滑套22和滑杆21的方式实现升降座2和机架1之间的滑动连接，结构简单，易于加工生产。
本实施例中，弹性组件包括与滑杆21数量一致且一一对应的伸缩弹簧5，各伸缩弹簧5套设在对应滑杆21外部，且各伸缩弹簧5的两端分别对应与机架1和滑套22相抵。如此，通过更换不同弹性强度的伸缩弹簧5，便能调节绞吸头4相对于机架1向下移动的程度即绞吸头4单次作业的深度，而且伸缩弹簧5易于得到，降低了生产成本。
其次，升降座2的两侧还设有可沿机架1上下滑动的导向板24，通过该导向板24可使升降座2更加稳定的沿机架1进行上下移动，从而进一步提高了与升降座2相连的绞吸头4运行时的稳定性。
本实施例中，升降座2连接有用于供牵拉绳连接以提升升降座2的连接部23。其中，升降座2和机架1之间还设有将升降座2固定在机架1上的插销6，在进行作业时，首先将插销6取下，接着将牵拉绳与连接部23进行连接，紧接着，将整个清理装置吊升并下放到河道 底座进行作业。这样，对升降座2进行吊升时，升降座2在牵拉绳的作用下相对于机架1向上移动，直至机架1到达河道底部，牵拉绳不再对升降座2进行提升。此时，升降座2和与升降座2相连的绞吸头4在自身重力的作用下开始沿机架1向下移动，当绞吸头4与砂石接触时开始对砂石进行搅碎和收集。如此，通过对连接部23进行提升，便能使升降座2和绞吸头4在自身重力的作用下沿机架1向下移动，而且还无需设置其他零部件，结构简单，便于操作。
本实施例中，收集运输机构3包括一个以上输送泵31，每个输送泵31至少连接一个绞吸头4；输送泵31安装在升降座2上。具体的，可设置成一个输送泵31连接两个绞吸头4，或者一个输送泵31连接三个绞吸头4或者其他形式，如此，提高了整个清理装置的搅碎收集能力。
本实施例中，输送泵31的下方设有呈喇叭状的收集口311，收集口311供被搅碎后的砂石进入输送泵31内。这种结构的收集口311不仅利于砂石的快速吸入，还减少对水体的扰动。其中，收集口311的旁侧还设有输送管道32，该输送管道的一段通过回转接头33安装在机架1上，可通过调节该回转接头33，调整输送管道32的输送方向，将砂石往不同角度进行运输。
本实施例中，机架1设有多个向下延伸用于插入砂石中以将机架1支撑固定在砂石上方的固定桩11。其中，固定桩11的下端为圆锥体，在对水下砂石清理装置进行下放时，圆锥体插入砂石内，这样便将整个水下砂石清理装置固定在水底，而且在绞吸头4作业时，可防止绞吸时反作用力过大而使整个装置发生旋转。
本实施例中，机架1上设有一个以上用于连接起吊设备的吊耳12和一个以上用于驱动机架1在水下移动的螺旋桨13。在将清理装置安装在水底时，通过驱动螺旋桨13可使整个清理装置发生移动，如此，可将清理装置准确的安装在清理点，结构简单，提高了清理装置安装时的精确度。
此外，机架1上还设有灯光摄像系统14、深度计15、惯导16、电控仓17、定位信标18和照明灯19等，通过上述各零部件可帮助工作人员清楚的看到清理装置在水底的情况，并了解清理装置的基本情况，如装置此时的离底高度，作业水深，作业状况等。便于工作人员对清理装置的作业位置进行调整，加快了安装进程。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例。对于本技术领域的技术人员来说，在不脱离本发明技术构思前提下所得到的改进和变换也应视为本发明的保护范围。
