Description

新式排灌管装置 技术领域
本发明涉及用于滴灌***中的排灌管装置，尤其涉及一种在不同位置都有非均匀排 列排灌孔的新式排灌管装置。 . 背景技术
传统的排灌管的排水方式， 都是由水份穿过分布在管壁的疏水孔口， 或过滤布的孔 隙， 来进入去水管道内， 再经主去水通道来排出于管道外面。 容易堵塞疏干孔， 而在排 水时，.主去水通道的排水功效亦极差； 而且当水份穿过疏水孔口或过滤布时， 大多会带 动及附有砂泥成份， 日积月累下， 便会将穿过管壁的疏水孔口或过滤布的孔隙堵塞， 不 能再产生排水作用， 但如将在管壁的疏水孔口直径扩大， 就会引致去水管的管体抗压强 度减少， 导致管体破裂， 而且当有大粒体积的砂泥， 经由扩大后的疏水孔口， 来进入管 道内时， 便会在管道的底部积聚， 减少管道的排水面积， 甚至于引致堵塞管道。而且当 该排灌管用在斜坡时， 现存疏水管道的出水位置， 有植物落地生根， 当植物长大后， 便 会堵塞了疏水管道的出水口。此种因植物落地生根， 引致堵塞现象的产生， 主要也是因 为在疏水管道的出水位置， 有大量砂泥， 被水冲积而结聚管道内的底部， 如果是冲积至 接近管道的出水位置， 便会成为植物萌芽生长的温床， 当植物枝叶茂盛的长大后， 便会 堵塞管道的出水口； 也可能是因为现在使用中的疏水管， 是在圆周的管壁上， 平均地开 设疏水孔， 所以令植物的种子， 就算在很少砂泥积聚的出水位置， 也能将生长的幼根， 伸进入开设在疏水管底部疏水孔的空隙中， 而在接近底部的疏水孔中落地生根， 枝叶茂 盛的生长后， 便会堵塞管道的出水口。
发明内容
本发明的目的是提供一种新式排灌管装置，通过在排灌管上设置有在不同水平位置 的内、 外壁排灌孔， 从而通过流体之间的压力差达成滴灌， 避免泥沙堵塞管道出水口排 灌管， 克服了现有排灌管装置存在的不足。 技术方案
为实现上述目的， 本发明采用了下述技术方案： ' 这种排灌管装置， 包括外管和开设于外管壁上的若干外壁排灌孔， 在外管管道内还 设置有一条主水道， 主水道的壁上高于外壁排灌孔的位置处设置有若干内壁排灌孔。
所述的主水道为水槽, 该水槽通过底部及顶部耳片与外管内壁相固接， 内壁排灌孔 设置于耳片上。
所述的外管截面为圆， 或者其与形成主水道的水槽截面相对应处的外管截面相似。 所述的水槽截面为马蹄形或者 U形或者 V形； 所述的水槽高度约为 1/2管体高度。 所述的主水道为一内管， 该内壁排灌孔设置于内管壁两侧的内壁上； 所述的内壁排 灌孔设置于内管内壁若 1/2内管高度处； 所述的管表面为凹凸相间的内管表面与外管表 面。 或者
所述的外管包括不连续的若干段， 每段在两端处变小与内管连接。
所述的外管顶部处设置有若干细小的微渗孔。
所述的内壁排灌孔可为圆形、 椭圆形或者方形。
还可以在内管与外管之间还设置有一条或者一条以上的副水道。
所述 ,的形成副水道的内壁为在内管与外管之间对应的若干隔条。
通过上述技术方案， 本发明具有下述有益效果：
1. 由于排灌管道的外在排灌孔出入口，是设计接近在底部的，当包围管道的泥土充 满水份后，便会发现在管道外水份的水平位置高于在管道内接近中央水平位置的内在排 灌孔， 因此便产生出由两个不同髙低水平位置的落差压力， 而此落差压力， 便会把管道 外的水份，被落差压力及渗透力推进入在管道底部的外在排灌孔中，经过内在的排灌孔， 再推动至主水道里， 再经由主水道， 而排流出管道外， 从而极不容易发生堵塞的现像。
2. 因为在排水过程中， 只是利用砂泥的自我过滤作用， 落差压力及渗透力将水份， 渗进入在管道底部的排灌孔中， 所以在排水运作期间， 亦不会有冲水压力的产生。 因此 自然不会带动大量的砂泥颗粒， 进入排灌孔道管内， 引发堵塞情形。
3. 而且该灌管道是可以用特制的高压水清洁工具， 定期做保养清洁， 延续排水或 灌溉的功能及工作年期。

具体实施方式
下面结合附图对本发明做进一步说明；
如图 1、 图 2所示， 该排灌管装置第一实施例， 包括圆形的外管 1和开设于外管底 部上的若干外壁排灌孔 2， 在外管管道内还设置有一条主水道， 该主水道为水槽 4， 在 水槽的壁上高于底部排灌孔位置处设置有若干内壁排灌孔 3， 该水槽通过底部和顶部的 耳片 5与外管内壁相固接， 内壁排灌孔 3设置于耳片上。所述的外管截面为圆， 所述的 水槽高度约为 1/2管体高度， 水槽截面为马蹄形。
与现有技术相比， 使用的时候， 首先将水源， 经过混合肥田料***， 成为混合了肥 田料的灌溉水份后， 便根据农作物的所需要份量及每日的灌溉次序， 引导入已安置在农 田里的灌溉管。 当灌溉水份引进入马蹄形的主水道时， 灌溉水份的水平位置亦会升 至 在管道内， 接近中央水平位置的内在排灌孔， 当管道内水份的水平位置高于管道外的时 候， 便产生出由两个不同高低水平位置的落差压力， 而此落差压力， 便会将管道内的灌 溉水份， 推进入在管道内接近中央的内在排灌孔内， 灌溉水份再利用渗透压力， 由马蹄 形的主水道， 经过内在棑灌孔， 引流出在接近管道底部所开设的外在排灌孔的泥土里， 直接让泥土吸收所需要的水份及养分， 不必被阳光蒸发及风化灌溉水份， 达到节水及定 时与定量的环保灌溉目标。 而该安置在农田里的溉灌管， 还有另一种用途， 便是当有大 降雨量时， 就会令农田被水淹没， 这时候， 便可将灌溉管变动为排水***， 帮助排出农 田里的大量积水， 一物二用。
由于将排灌管埋在土地里， 当在砂泥中的水份， 经过由水压的高低落差作用后， 水 份便由道管外的高水平位置，经由位于底部的外在排灌孔，渗透入马蹄形的主去水道中， 而在渗透的过程中， 水份是经过包围在管道外的土壤及砂泥， 才能够渗透入外在排灌孔 内， 情形就如经过砂泥的自我过滤作用， 能够将比较大体积或粒状的土壤砂泥， 自我隔 滤在底部的外在排灌孔之外。而以上的渗透作用， 亦令到包围在管道外的土壤砂泥， 不 会直接被水份带动， 而冲进入外在排灌孔内， 引起管道堵塞。 而在实验中发现， 当水份 渗透入排灌孔的孔道时， 会发现水份有两段式的较明显分隔， 即是水份如夹杂土壤成份 较为多的部份， 是会停留在排灌孔的孔道内的下游部份， 而夹杂土壤成份较为少量的水 份，因为受到体积的质量所影响，便会首先进入主引水道内，亦即所有经过内在排灌孔， 再流入马蹄形状的主去水道中的水份， 只会夹杂极幼小的土壤份子， 不会有附带的大型 土壤或砂泥来堵塞管道， 而能令排水顺畅。 当在管道外的土壤及砂石， 经过砂泥的自我 过滤作用后， 便只有极细微的土壤成份， 才能混杂在水份中， 而随之一起带进入主去水 道中。而排灌管道的主去水道， 是设计类似为马蹄形状， 这是已知的带水面积最大及最 佳去水量， 与及结构强度极高的形状之一， 所以当这些混杂着细微土壤的水份， 被带动 进入马蹄形主去水道时， 亦极容易被马蹄形的设计形状， 所带动的强大水流而冲刷出管 道外， 因此排灌管道亦具有自我清洁功能。
另外， 该排灌管道是可以用特制的高压水清洁工具， 定期做保养清洁， 加强管道的 工作效能及延续工作年期。
图 3、 图 4为本发明第二实施例， 其与第一实施例的不同之处在于： 所述的水槽 4a 截面与相对应处的外管 la截面相似， 也为马蹄形。
图 5、.图 6、 图 7为本发明第三实施例， 所述的主水道是一内管 4b， 该内壁排灌孔 3b设置于内管壁两侧的内壁上； 所述的内壁排灌孔设置于内管内壁若 1/2内管髙度处； 所述的管表面为凹凸相间的内管表面与外管表面， 同样有外壁排灌孔 2b设置于底部。 图 8、 图 9、 图 10为本发明第四实施例， 所述的外管 lc包括不连续的若干段， 每 段在两端处变小与形成主水道的内管 4c连接， 同样， 在外管上设置有外壁排灌孔 2c， 在内管上设置有内壁排灌孔 3c。
图 11、 图 12为本发明第五实施例， 其与第一实施例不同之外在于， 所述的内壁排 灌孔 3d是方形的。
图 13为本发明第六实施例， 其与第一实施例的不同之处在于， 所述的外管 le上与 外壁排灌孔相对的顶部设置有细小的微渗孔 7。
图 14为本发明第七实.施例， 在内管与外管之间还设置有两条副水道， 所述的形成 副水道的内壁为在内管与外管之间对应的若干隔条 8。当内部分别为两层真空的结构后， 划分为主水道部份及排灌孔部份， 当需要被冷却的物料在其中一层真空的结构内部流通 时， 便可与在另一层流动的物料， 同时于排灌孔范围内， 进行热交换。 例如水份、 机油 与气体等等。
通过上述实施例， 该发明除可以应该在灌溉领域内， 还可以应用在挡土墙及草地面 斜坡排水； 或者机场跑道、 公路及行车天桥的路面排水； 也可以是草地场所排水， 如足 球场，网球场；也可以在建筑物的内在渗漏监察方面起作用；作为水平的灌浆加压管道; 也可以放置在垃圾堆填区及填海堆填区； 以及作为土石坝主体排水； 安装在混凝土大坝 底部； 农地高效能节水渗灌***； 箱型灌溉***等方面。
