Abstract
一种可伸缩软管，其管壁由围绕可伸缩软管的延伸方向盘绕的皱折部（11）构成。其优点在于，解决了软管难以保持一定的折叠或者伸展状态的问题，不仅可以较为方便地进行伸缩，且可以在伸展或者折叠的任一状态下保持其形状，有利于地下布线设计，同时不受材质老化的影响，具有较好的应用价值。
Description
本发明涉及用于雨水收集或者排水的软管，属于绿色环保领域，特别涉及一种可伸缩软管，可以在伸展或者折叠的任一状态下保持其现状。
在园林绿化以及土壤改造的过程中，需要用到一些排水管或者汲水管，为了防止土壤中的水分或者其他化学元素的侵蚀，同时也是为了降低制造成本，通常使用塑料管作为排水管或者汲水管。
现有技术中，已经出现使用环形的波纹塑料管作为排水管的例子。这些环形的波纹管的管壁为间隔设置的多个环形圈，具有一定的伸展以及收缩能力，可以压合收缩。问题是，这些环形波纹管的收缩能力极为有限，其伸缩完全地依靠于塑料管管壁自身的弯曲，在收缩和伸展的过程中，管壁部分弯曲幅度较大，容易引起脆性折断，同时在塑料老化时，其伸缩能力也随着塑料管管壁的弯曲能力而大幅减弱，往往无法很好地进行伸缩，一般而言，通常无法伸展或者折叠至预定的位置而仅仅只能停留在部分伸展部分折叠的中间状态，极大地妨碍了塑料管的使用。另外，目前的可伸缩波纹管的伸缩性能不佳，受到材质的影响较大，尤其是，通常的可伸缩软管的材质为塑料，塑料本身就具有相当的弹性，因此折叠后的软管会在塑料本身弹性的作用下回复伸展状态，波纹管折叠不整齐，无法很好地保持折叠状态。
由此，有必要研制一种可以尽最大可能地减少管壁的弯曲幅度，同时可以在伸展或者折叠状态下保持其形状的可伸缩软管。
发明内容
本发明针对现有技术中可伸缩软管的管壁容易受老化等因素的影响，使软管的伸缩能力下降的缺点，提供了一种新型的可伸缩软管，可以在材质老化受
损的情况下仍然保持其原有的伸缩能力。
为实现上述目的，本发明可采取下述技术方案：
可伸缩软管，可伸缩软管的管壁由多个围绕可伸缩软管的伸展方向盘绕的皱折部构成；每个皱折部包括第一褶皱壁以及第二皱折壁，第一皱折壁以及第二皱折壁均沿着皱折部的盘绕方向延伸；皱折部朝向可伸缩软管的外侧凸出，第一皱折壁以及第二皱折壁分别位于皱折部凸出的方向的两侧；沿着皱折部的盘绕方向，第一皱折壁的一侧与第二皱折壁相连接，第一皱折壁的另一侧与相邻皱折部的第二皱折壁相连接；第一皱折壁沿着皱折部的延伸方向的截面包括底凹段、第一连接段、第二连接段以及顶凹段，底凹段、第一连接段、第二连接段以及顶凹段由第一皱折壁靠近相邻皱折部的一侧至第一皱折壁靠近第二皱折壁的一侧首尾相接排列；顶凹段以及底凹段的底部均朝向皱折部凸出的相反方向凸出；第一皱折壁还包括位于顶凹段与第二连接段之间的突起段，突起段的两端分别与顶凹段以及第二连接段相连接；第一连接段朝向皱折部的外侧凸出；第二连接段朝向皱折部的内侧凹入；第二皱褶壁沿着皱折部的延伸方向的截面包括第三连接段；第三连接段朝向皱折部的内侧凹入。
于本发明的实施例中，可伸缩软管的管壁还包括有至少两列的通孔；每列通孔均沿着可伸缩软管的伸展方向顺序排列。
于本发明的实施例中，当可伸缩软管处于折叠状态时，通孔围绕可伸缩软管均匀间隔排列；在可伸缩软管的伸展方向上，通孔呈一直线排列。
于本发明的实施例中，通孔位于第一皱褶壁与第二皱褶壁的连接处。
于本发明的实施例中，第一皱折壁沿着皱折部的延伸方向的截面还包括重叠段；重叠段的一端与第二连接段相连接，重叠段的另一端与突起段相连接。
于本发明的实施例中，重叠段包括第一重叠段以及第二重叠段；第一重叠段为第二连接段的延伸，第二重叠段为突起段的延伸；第二重叠段相对第一重叠段位于皱折部的外侧。
于本发明的实施例中，第一重叠段沿皱折部的内侧侧面由第二连接段延伸直至第三连接段。
于本发明的实施例中，第二皱褶壁沿着皱折部的延伸方向的截面还包括第四连接段；第四连接段位于第三连接段的远离第一皱褶壁与第二皱褶壁的连接处的一端，第四连接段的一端与第三连接段相连接；第四连接段朝向皱折部的外侧凸出。
于本发明的实施例中，第二连接段的长度等于或者至少稍大于第一连接段的长度。
于本发明的实施例中，顶凹段的底部朝向皱折部凸出的方向的一侧。
本发明具有以下的显著技术效果：
软管可以方便地伸展或者折叠，并可以稳定地保持在伸展或者折叠状态下。在伸展状态下，软管呈现类似螺旋形的外观，而在折叠状态下，软管折叠为一直管，且长度大为收缩，减少了运输时所需的存放空间，降低了运输成本。此外，本产品通常应用于土壤改造或者庭院绿化等场合，由于本产品的整体伸缩率受材质影响较小，使用寿命长，降低了使用成本，有利于绿化环保，在国内外的园林绿化以及土壤改造领域中得到了普遍的推广应用，社会反响良好。进一步地，位于第一皱折壁的顶凹段以及底凹段均具有类似S形的弯曲结构，减少了管壁弯曲的幅度，可以有效地防止管壁由于过度弯曲导致的破裂，特别是在材质发生老化时，可以降低由于老化导致的材质脆性提高而引起的管壁破损情况的出现，提高产品的使用寿命。
进一步地，管壁上还设置有至少两列的通孔，在软管的折叠状态下，每列通孔均沿软管的长度方向呈一直线排列，有利于前期加工。而当软管处于伸展状态下，每列通孔随着皱折部的转动，呈现螺旋形，有利于使用过程中，软管的各个方向上的水流或者土壤中的水分进出软管，有效地减少了软管内外水分的淤积。而管壁外侧围绕的纱布则可以防止土壤块或者其他的杂质进入软管，防止软管堵塞。

每个皱折部11包括第一皱折壁100以及第二皱折壁200，如图2、3所示，图2、3、4中为了简明起见，将管壁厚度隐去，只保留线条，第一皱折壁100以及第二皱折壁200均沿着皱折部11的盘绕方向延伸；皱折部11朝向远离可伸缩软管10的外侧凸出，暨由皱折部11的延伸方向D3的截面看，皱折部11的断面均呈现波峰形状，波峰的峰顶就是皱折部11的凸出方向，第一皱折壁100以及第二皱折壁200分别位于皱折部11凸出的方向的两侧；沿着皱折部11的盘绕方向，第一皱折壁100的一侧与第二皱折壁200相连接，第一皱折壁100的另一侧与相邻皱折部12的第二皱折壁相连接。
第一皱折壁100沿着皱折部11的延伸方向D3的截面包括底凹段101、第一连接段102、第二连接段103以及顶凹段104；底凹段101、第一连接段102、第二连接段103以及顶凹段104自第一皱折壁100靠近相邻皱折部12的一侧至第一皱折壁100靠近第二皱折壁200的一侧首尾相接排列。
顶凹段104以及底凹段101的底部均朝向皱折部11凸出的相反方向凸出；
顶凹段104以及底凹段101沿着盘绕方向形成两条凹槽，其中，顶凹段104位于靠近皱折部11的波峰顶端部位，而底凹段101则位于皱折部11的波谷的最底端，在可伸缩软管进行伸展或者折叠的过程中，顶凹段104以及底凹段101均可实现弯曲，保证可伸缩软管的皱折部11可以叠合在一起。
第一皱折壁100还包括位于顶凹段104与第二连接段103之间的突起段105，突起段105的两端分别与顶凹段104以及第二连接段103相连接；突起段105沿着盘绕方向形成一条突棱，便于第一皱折壁100弯折并向第二皱折壁200靠拢。
第一连接段102朝向皱折部11的外侧凸出；第二连接段103朝向皱折部11的内侧凹入；第一连接段102以及第二连接段103分别用于保持可伸缩软管的折叠状态以及伸展状态，第一连接段102朝向外侧凸出，有利于处于伸展状态的软管保持形状，而第二连接段103朝向内侧凹入则有利于处于折叠状态的软管保持形状。
第二皱折壁200沿着皱折部11的延伸方向D3的截面包括第三连接段201；第三连接段201朝向皱折部11的内侧凹入，有利于第三连接段201在软管伸展和折叠的过程中保持既有形状不变。可伸缩软管10的管壁还包括有至少两列的通孔300(图中仅绘出一列)，优选为四列或者六列的通孔300；每列通孔300均沿着可伸缩软管10的伸展方向D1顺序排列。通孔300用于水流或者土壤中的水分进入软管内腔。
当可伸缩软管10处于折叠状态时，通孔围绕可伸缩软管10均匀间隔排列；在可伸缩软管10的伸展方向D1上，通孔300呈一直线排列，而当软管处于伸展状态时，由于在伸展的过程中，皱折部11均会沿着盘绕方向转动一个较小的角度，因此，在伸展状态下，每列通孔300均呈螺旋状排列于软管管壁周围。通孔300位于第一皱折壁100与第二皱折壁200的连接处，便于加工。
第一皱折壁100沿着皱折部11的延伸方向D3的截面还包括重叠段106；重叠段106的一端与第二连接段103相连接，重叠段106的另一端与突起段105相连接。
重叠段106包括第一重叠段1061以及第二重叠段1062；第一重叠段为第二连接段103的延伸，第二重叠段1062为突起段105的延伸；第二重叠段1062相对第一重叠段1061位于皱折部11的外侧。
第一重叠段1061沿皱折部11的内侧侧面由第二连接段103延伸直至第三连接段201。于另一实施例中，第一重叠段1061亦可以一直沿着第三连接段201延伸至底凹槽101附近，以进一步提高第二皱折壁200的强度。此外，作为另一种可选的结构，第二重叠段1062可以沿着第二连接段103的外侧表面延伸直至第一连接段102的与底凹段101相连接的末端。
重叠段106是通过将两条沿着盘绕方向延伸的塑胶或者树脂片叠合而成的结构，重叠段106可以强化顶凹段104的结构强度，其第一重叠段1061的延伸部分可以强化第三连接段201的结构强度，第二重叠段1062的延伸部分可以强化第二皱折壁200的结构强度，有利于在折叠和伸展过程中，顶凹段104与第三连接段201可以保持其原有的形状。
第二皱折壁200沿着皱折部11的延伸方向D3的截面还包括第四连接段202；第四连接段202位于第三连接段201的远离第一皱折壁100与第二皱折壁200的连接处的一端，第四连接段202的一端与第三连接段201相连接；第四连接段202朝向皱折部11的外侧凸出。第四连接段202在折叠时可以稍稍地向皱折部11的内侧弯曲，有利于折叠。
第二连接段103的长度等于或者至少稍大于第一连接段102的长度。顶凹段104的底部朝向皱折部11凸出的方向的一侧。
此外，还包括围绕于可伸缩软管10管壁外侧的纱布。纱布可以防止土壤或者其他杂物通过，防止软管被堵塞。
可伸缩软管10包括折叠状态以及伸展状态，当可伸缩软管10收缩为折叠状态时，底凹段101的两端朝向中心弯曲收缩，顶凹段104的两端则远离顶凹段104的中心扩张，同时，突起段105朝向可伸缩软管10的内侧弯曲，因此，由突起段105至底凹段101之间的部分在折叠收缩时，以突起段105的凸出的顶点为中心，朝向第二皱折壁200的方向转动，直至第一皱折壁100与第二皱
折壁200相互贴合，成为折叠状态。
进一步地，第一皱折壁100沿着皱折部11的延伸方向D3的截面为一条曲线，如图4所示，该曲线的一端至另一端的直线距离为c，暨，底凹段101的底部中心为O1点，第一皱折壁100与第二皱折壁200的连接处在截面上的点为O2点，因此O1点至O2点之间的距离为c；相邻皱折部12的第一皱折壁与第二皱折壁的连接处在截面上的点为O3点，则O2点至O3点之间的直线距离为a；进一步地，经过O1点与O2点的直线为L1，经过O1点与O3点的直线为L2，L1与L2之间的夹角为α；与底凹段101的一端相连接的第一连接段102的切线方向所在的直线为L3，与底凹段101的另一端相连接的第四连接段202的切线方向所在的直线为L4，则L3与L4之间的夹角为β；顶凹段104的压痕距离，暨顶凹段104的底部中心至O2点之间的距离为H，底凹段101的压痕距离，暨第一重叠段1061的延伸部分沿着第二皱折壁200的内侧表面延伸的末端端点至底凹段101的底端中点(或者是底凹段101位于皱折部11的波谷的最底端)之间的距离为E。则可伸缩软管10的大小规格为：
a＝10mm-16mm；
c＝8mm-14mm；
α＝20°-80°；
β＝60°-140°；
H＝0-4mm，当H＝0，则顶凹断104位于皱折部11的波峰的顶端正上方；
E＝0-5mm，当E＝0时，则第一重叠段1061沿着第二皱折壁200的内侧表面一直延伸至底凹段101的底端中心位置；
上述大小规格是在可伸缩软管的管口直径在2英寸至8英寸的规格下的数据，其中，管口直径可以是软管的内径，也可以是软管的外径。
进一步地，下表1列出了不同管口直径下的可伸缩软管10的可选的大小规格：
表1
应当指出的是，上表中所记载的大小规格均为优选项，但并不意味着本实施例所记载的可伸缩软管仅仅只能选择上表所选择的数据，其他任何符合本实施例的软管的大小规格均可。
将上述实施例所得到的可伸缩软管与现有市场上可以买到的一些伸缩软管进行对比，结果如下表2所示：
表2
综上所述，本发明实施例提供的软管可以方便地伸展或者折叠，并可以稳定地保持在伸展或者折叠状态下。在伸展状态下，软管呈现类似螺旋形的外观，而在折叠状态下，软管折叠为一直管，且长度大为收缩，减少了运输时所需的存放空间，降低了运输成本。此外，本产品通常应用于土壤改造或者庭院绿化等场合，由于本产品的整体伸缩率受材质影响较小，使用寿命长，降低了使用成本，有利于绿化环保，在国内外的园林绿化以及土壤改造领域中得到了普遍的推广应用，社会反响良好。进一步地，位于第一皱折壁的顶凹段以及底凹段均具有类似S形的弯曲结构，减少了管壁弯曲的幅度，可以有效地防止管壁由于过度弯曲导致的破裂，特别是在材质发生老化时，可以降低由于老化导致的材质脆性提高而引起的管壁破损情况的出现，提高产品的使用寿命。
总之，以上仅为本发明的较佳实施例，凡依本发明申请专利范围所作的均等变化与修饰，皆应属本发明专利的涵盖范围。
