二喷嘴朝向耙齿进行高压喷水。
本发明的优点在于:本发明通过倾角传感器测量出两侧吸泥管的水平和垂直角度以及所在水下的深度、船舶横向倾斜和纵向倾斜、吸泥管的水平位移以及相对吸水深度,根据这些数据,可以计算出船体的吃水深度和耙头在河道中所处的位置,第一驱动装置上的第一拉杆结合倾角传感器的数据驱动活动罩,调整耙齿的耙泥角度,采用第一高压喷水装置对水底垂直高压冲水,第一高压喷水装置上的第一冲水装置之间设有隔板,隔板的长度大于第一冲水装置的长度,隔板可以防止第一喷嘴对水底进行高压喷水时相互之间干扰,而且隔板的设置可将水垂直冲落到污泥上,疏松水底土块,第二高压喷水装置对水底倾斜高压冲水,第二高压喷水装置与水平面的倾斜角为30°~50°,这样第一高压喷水装置和第二高压喷水装置相互配合对喷,加大对水底土块的疏松程度;同时第二拉杆控制驱动块运动,驱动块与驱动压块之间设有弹性复位装置,弹性复位装置起到对驱动块弹性复位的作用,使得驱动压块上下运动,驱动压块带动平移机构左右移动,由于平移机构上设有移动通孔,固定板的两侧设有定位轴,定位轴活动连接于移动通孔中,使得平移机构驱动耙齿上下运动,对于耙齿的设计结构,其包括连接部和齿部,齿部的外端的横截面积呈三角形状,耙齿的齿部截面直接关系到耙泥的深度,横截面积呈三角形状可以增加耙齿对污泥的力度,提高耙头的挖掘能力,这样耙齿可在水底开挖出一段槽口,方便耙齿耙泥时将质硬的污泥耙起,降低了耙头的挖掘阻力,提高耙头的挖掘能力和疏浚效率,具有挖泥效率高和生产成本低的效果;
本发明的技术方案首先在吸泥时,除杂装置先将比较大的杂物阻挡,避免堵塞,第一挡板和第二挡板上的阻隔孔可以将规格允许的杂质进行通过处理,大的杂物拒绝,工作时间长了以后阻隔孔会逐渐被杂物封闭,这时候高压气枪对其进行高压喷气疏通阻隔孔,然后继续工作,高压气枪上的防逆流橡胶圈能够阻止液体对高压气枪逆流。

下面结合说明书附图,对本发明进行进一步详细的说明。
如图1至10所示的一种自航高效耙吸式挖泥船,包括船体1、设于船体1上的吸泥机构2、设于吸泥机构2上的耙头3、设于船体1中的泥仓4、设于船体1上的推进机构5和设于船体1上的卸泥机构6;耙头3上设有活动罩,活动罩8的进泥口设有除杂装置38,除杂装置38包括一横向设于活动罩8上的第一挡板39以及若干纵向均匀设于第一挡板39上的第二挡板40;第一挡板39和第二挡板40上均设有若干成阵列排列的阻隔孔41;第二挡板40与第一挡板39之间呈45°至60°夹角设置;
除杂装置38一侧还设有一清理装置,该清理装置为正对除杂装置38的第一挡板39和第二挡板40的高压气枪,高压气枪具有若干喷嘴,喷嘴一一对用第一挡板39和第二挡板40上的每一个阻隔孔41,高压气枪出气口设有防逆流橡胶圈。
推进机构5使船体1具有良好的航行性能,使得船体1具有自航能力。吸泥机构2包括吊架21、滑动装置22和吸泥管23,吊架21设于船体1上,吸泥管23与耙头3连通,吊架21通过滑动装置22将吸泥管23吊放到水底,耙头3进行耙泥作用,利用泥浆泵的真空作用,耙头3和吸泥管23自河底吸收泥浆进入船体1中的泥仓4中,以边吸、边航行的方式工作,使得船体1具有自载能力。泥仓4中污泥满后,船体1起耙航行至抛泥区开启卸泥机构6上的泥门卸泥,将挖起的泥土排出船外,使得船体1具有自卸能力。
对于一些河道来说,由于河水的浑浊,自航高效耙吸式挖泥船在操作时很难对河水下的耙头进行实物观察,无法了解耙头3在河道中所处的位置和挖泥的深度,针对这个情况。
本发明在吸泥机构2上设置倾角传感器7,倾角传感器7的测量范围为±30°,测量精度为0.01°,其所获得的信号输出方式为数字量输出或模拟量输出,工作温度为-40℃~85℃,抗冲击性为1000g。倾角传感器7测量出两侧吸泥管23的水平和垂直角度以及所在水下的深度、船舶横向倾斜和纵向倾斜、吸泥管23的水平位移以及相对吸水深度,根据这些数据,可以计算出船体1的吃水深度和耙头3在河道中所处的位置。
耙头3上设有活动罩8,活动罩8的长度一般在1000mm~1700mm之间,宽度一般在1300mm~2900mm之间,活动罩8的具体长度和宽度主要
根据吸泥管23的直径进行确定。活动罩8上设有第一驱动装置9,第一驱动装置9包括第一拉杆24和基座25,第一拉杆24转动连接于基座25上,基座25固定连接于活动罩8上,第一拉杆24拉动基座25,第一拉杆24结合倾角传感器7的数据驱动活动罩8,调整耙齿的耙泥角度。活动罩8上设有驱动压块10,驱动压块10的顶部设有第二驱动装置11,第二驱动装置11包括第二拉杆26和驱动块27,第二拉杆26控制驱动块27上下运动,驱动块27与驱动压块10之间设有弹性复位装置28,弹性复位装置28起到对驱动块27弹性复位的作用。第二驱动装置11对驱动压块10上下驱动作用。活动罩8的内部设有平移机构12,驱动压块10纵向驱动平移机构12:平移机构12上设有卡槽29,驱动压块10驱动连接于卡槽29中,实现驱动压块10纵向驱动平移机构12。平移机构12上设有移动通孔13,移动通孔13斜向上设置。活动罩8的内部设有耙齿外壳14,耙齿外壳14设于平移机构12的下方,平移机构12在耙齿外壳14上横向移动。耙齿外壳14中设有衔接块15,衔接块15的倾斜面上设有耙齿16,耙齿16的设计和选用根据水底土质决定,合理选用耙齿16的形式和尺寸直接关系挖泥的效率和生产成本的高低。耙齿16包括连接部30和齿部31,齿部31的外端的横截面积呈三角形状,耙齿16的齿部31的截面直接关系到耙泥的深度,横截面积呈三角形状可以增加耙齿16对污泥的力度,提高耙头3的挖掘能力。衔接块15的顶面上设有固定板17,固定板17的两侧设有定位轴18,定位轴18活动连接于移动通孔13中:当定位轴18处于移动通孔13的底部时,耙齿16伸出的有效长度最长;当定位轴18处于移动通孔13的顶部时,耙齿16缩进的有效长度最短,定位轴18的不断运动使得耙齿16不断运动,这样耙齿16可在水底开挖出一段槽口,方便耙齿16耙泥时将质硬的污泥耙起。活动罩8的内侧垂直设有第一高压喷水装置19,第一高压喷水装置19设于耙齿16的一侧,第一高压喷水装置19包括集水装置32、第一冲水装置33和第一喷嘴34,集水装置32为第一冲水装置33提供水,第一冲水装置33给第一喷嘴34提供动力,第一喷嘴34对水底进行高压喷水,第一冲水装置33之间设有隔板35,隔板35的长度大于第一冲水装置33的长度,隔板35可以防止第一喷嘴34对水底进行高压喷水时相互之间干扰,而且隔板35的设置可将水垂直冲落到污泥上,疏松水底土块。活动罩8的外端倾斜设有第二高压喷水装置20,第二高压喷水装置20包括第二冲水装置36和第二喷嘴37,第二冲水装置36给第二喷嘴37提高动力,第二喷嘴37朝向耙齿16进行高压喷水,第二高压喷水装置20与水平面的倾斜角a为30°~50°,优先选用40°。第一高压喷水装置和第二高压喷水装置相互配合对喷,加大对水底土块的疏松程度,最明显的效果就是挖掘深度增加。
本发明通过倾角传感器7测量出两侧吸泥管23的水平和垂直角度以及所在水下的深度、船舶横向倾斜和纵向倾斜、吸泥管23的水平位移以及相对吸水深度,根据这些数据,可以计算出船体1的吃水深度和耙头3在河道中所处的位置,第一驱动装置9上的第一拉杆24结合倾角传感器7的数据驱动活动罩8,调整耙齿16的耙泥角度,采用第一高压喷水装置19对水底垂直高压冲水,第一高压喷水装置19上的第一冲水装置33之间设有隔板35,隔板35的长度大于第一冲水装置33的长度,隔板35可以防止第一喷嘴34对水底进行高压喷水时相互之间干扰,而且隔板35的设置可将水垂直冲落到污泥上,疏松水底土块,第二高压喷水装置20对水底倾斜高压冲水,第二高压喷水装置20与水平面的倾斜角a为30°~50°,这样第一高压喷水装置19和第二高压喷水装置20相互配合对喷,加大对水底土块的疏松程度;同时第二拉杆26控制驱动块27运动,驱动块27与驱动压块10之间设有弹性复位装置28,弹性复位装置28起到对驱动块27弹性复位的作用,使得驱动压块10上下运动,驱动压块10带动平移机构12左右移动,由于平移机构12上设有移动通孔13,固定板17的两侧设有定位轴18,定位轴18活动连接于移动通孔13中,使得平移机构12驱动耙齿16上下运动,对于耙齿16的设计结构,其包括连接部30和齿部31,齿部31的外端的横截面积呈三角形状,耙齿16的齿部31截面直接关系到耙泥的深度,横截面积呈三角形状可以增加耙齿16对污泥的力度,增加耙头3的挖掘深度和挖掘宽度,有利于泥沙的液化和悬浮,这样耙齿16可在水底开挖出一段槽口,方便耙齿16耙泥时将质硬的污泥耙起,降低了耙头3的挖掘阻力,提高耙头3的挖掘能力和疏浚效率,具有挖泥效率高和生产成本低的效果。
本发明的技术方案首先在吸泥时,除杂装置38先将比较大的杂物阻挡,避免堵塞,第一挡板39和第二挡板40上的阻隔孔41可以将规格允许的杂质进行通过处理,大的杂物拒绝,工作时间长了以后阻隔孔41会逐渐被杂物封闭,这时候高压气枪对其进行高压喷气疏通阻隔孔41,然后继续工作,高压气枪上的防逆流橡胶圈能够阻止液体对高压气枪逆流,第二挡板40与第一挡板39之间的角度更有利于泥沙的流动,进一步的保证了泥沙的流畅防止泥沙阻塞,经过多次试验,45°至60°效果最佳。
以上所述仅是本发明的优选方式,应当指出,对于本领域普通技术人员来说,在不脱离本发明创造构思的前提下,还可以做出若干相似的变形和改进,这些也应视为本发明的保护范围之内。
