具体实施方式
下面结合实施例对本发明进行进一步阐述。应该指出，以下详细说明都是例示性的，旨在对本发明提供进一步的说明。除非另有指明，本发明使用的所有技术和科学术语具有与本发明所属技术领域的普通技术人员通常理解的相同含义。
请参阅图1，图1示出了一种塔架，所述塔架包括多段分片式塔架段100由下而上对接组成，需要说明的就是，本实施例中的分片式塔架段100的是由两个或以上分片塔架外壳组成，具体是通过由分片塔架外壳的纵向法兰对接在一起形成圆柱形塔架段，同时纵向法兰在塔 架的内部，分片塔架外壳通过导向机构200连接形成一个分片式塔架段100。
进一步，如图2所示，本实施例公开的分片塔架内部两端分别通过安装导向机构200实现两者的对接，保证分片塔架装配后纵法兰、满足公差要求，减少筒体错位，提高分片塔架段密封防水性。
具体的，如图3所示，本实施中安装导向机构200主要包括第一固定板210、第二固定板220、导向销230、卡扣240以及把手260。
进一步的，第一固定板210和第二固定板220分别固定在相互对接的两个分片塔架内璧面上，且设置在相对接的位置一侧，为了减少固定板端部的焊接应力，固定板的端部以圆弧形式过渡到塔架的壁面上，并且尾部打磨平滑过渡到筒体内壁上，以提高分片塔架疲劳等级。其中第一固定板210和第二固定板220为U型固定板，该U型固定通过两个纵向板固定在塔架的内壁面上，U型固定板与塔架内壁面组成的空间用于放置导向销230，所述第一固定板210和第二固定板220的纵向侧板上都设有销轴孔与导向销230上的销轴孔对接实现两者的连接。
见3图所示，本实施例中的第一固定板210的侧板上设有第一固定板固定销孔213，同时所述导向销230的导向销导向面233与第一固定板210上的第一固定板内表面211相对接实现两者的嵌套。同时在第一固定板210上还设有同于卡住的卡扣240的卡扣固定槽212。
进一步，第二固定板220的侧板上设有第二固定板上固定销孔a222和第二固定板上固定销孔b223，同时第二固定板220上的第二固定板内表面221也与导向销230的导向销导向面233的配合实现两者的 嵌套。同时在所述第二固定板220上固定第二固定板上固定销孔a222也是用来转动连接把手260的，所述扳手也是U型固定板，在该把手260的纵向侧板上设有三个固定销孔，该三个固定销孔呈三角分布，其中位于最外侧的卡扣安装孔263主要是用来与U型的卡扣240转动连接，卡扣安装在把手上上可以自由的转动，进一步把手外侧的纵向板上的把手固定销孔a261主要是用来与第二固定板220上的固定销孔a222相对接通过250a实现两者的连接，
下面详细说明一下通过安装导向机构将两个分片塔架片体对接在一起的使用过程：
第一步：参照图4，使用前，首先将卡扣240通过卡扣安装孔263与把手260连接到一起，第一固定销250穿过把手固定销孔一261、第二固定板上固定销孔a222、导向销固定销孔b232将把手260、导向销230、第二固定板220连接到一起。
第二步：参照图5-图6,首先，导向销230穿过第一固定板内部并且导向销导向面233与第一固定板内表面211具有一定配合关系；其次，将卡扣240置于第一固定板上的卡扣固定槽212内，扳动把手260使得塔架分片沿导向销230在安装导向结构作用下处于锁紧状态；最后，将第三固定销250穿过把手上的把手固定销孔b262及第二固定板上的第二固定板上固定销孔b223将把手锁死，同时将第二固定销250穿过第一固定板上的固定销孔213及导向销上的固定销孔a231，将安装导向结构完全锁死，从而为分片塔架装配起到导向及初预紧作用。
所以上述安装导向结构可提高分片塔架组装时快速定位安装要求，保证分片塔架装配后纵法兰满足公差要求，提高分片塔架段100密封防水性。
为了进一步的增强分片塔架纵向法兰的对接后密封性，见图9，本实施例在两个纵向法兰对接面上设置了密封堵420用于消除塔架分片纵法兰在分片塔架在生产、运输过程中产生的间隙及变形，增加塔架组装后的密封性。密封堵厚度根据相邻塔架分片纵法兰间间隙进行调整。
进一步，为了保证相邻的两个分片式塔架段100密封性，所述塔体在相邻的分片式塔架段100之间安装了密封条，如图7-8所示，所述密封条整体为T型件，该密封条包括密封条水平面412和密封条竖直面413，且所述水平密封条面412的端部连接呈箭头状的密封条尾部411，上述密封条410的使用方法，将密封条的水平密封条面412设置在相邻的相邻的分片式塔架的结合面，同时将竖直密封条面413与塔体的外壁贴合，同时依靠呈箭头状的密封条尾部411与塔体的内壁贴合，这样组成的密封系统效避免后期雨水、风沙、飞虫等的进入塔架内部。
除此之外，本公开的实施例还提供了一种塔体，该塔体包括由多段分片式塔架段100自下而上对接而成，每段分片式塔架段100均包括上述实施例提供的分片式塔架段密封系统。
需要说明的就是，本实施中提供的塔体相邻的分片式塔架段是通过分片式塔架段顶部或者是底部的环形法兰对接在一起，当上下两个 分片式塔架段环形法兰对接在一起时，也会有缝隙，外部的水也有可能会经过该缝隙进入塔体内部。
为了解决该技术问题，参照图9本实施例在分片塔架内部环形法兰对接缝隙处下面设置了集水系统300，所述集水系统300包括集水槽310、导流条320以及集水管路330，其中集水槽紧贴在分片塔架内部环形法兰对接缝隙处底部用于收集从缝隙处进入内部的水，导流条设置在缝隙处的两侧且紧贴环向法兰的内壁且与集水槽310的顶部相连接，用于将进入内部的水引流到集水槽310中，继而通过集水槽底部相连通的集水管路330引出塔外。
具体的，见图10-图12所示，所述集水槽310通过侧板a312、侧板b313、侧板c314、侧板d315以及底板316组成的一个锥形体，底板上设有集水槽接头317用于与集水管路330相连接，进一步，所述集水槽310的顶部通过面向环形法兰内壁方向倾斜设置的引流板311尖端抵在塔架分片环法兰切割缝下侧，以保证塔架分片拼接缝隙处雨水通过引流板流入集水槽中。
为保证集水槽310集水性能，在集水槽310的顶部安装处连接导流条320，如图10所示，本实施例中的导流条320的形状为阶梯状，其主要是为了贴合固定在环法兰及筒体表面，当然这并不是对本公开的导流条形状的限制，需要根据具体的环法兰的形状调整导流条的形状，所述导流条设有上端321和下端321，其中上端321为保证导流效果为扩口状，下端322贴合在引流板311两测将水引流到集水槽310内。
另外需要说明的就是，如图13-图14所示，在所述塔体内部，分片式塔架段100上的集水管路相互连通，所述塔架上位于最底部的分片式塔架段上的集水管路通过塔架底部排水管路引出塔架内部。
这样本公开实施例提供了塔架内部集水系统将通过分片塔架拼接缝处进入筒体内部的雨水通过塔架底部排水管路引出塔架内部，避免进水导致筒体、螺栓锈蚀及电器柜失效，同时配合分片塔架上的密封防水系统可保证筒体密封防水性，可有效防止可有效避免后期雨水、风沙、飞虫等的进入塔架内部，最终解决分片塔架密封防水短板问题。
应当说明的是，以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包括在本发明的保护范围之内。
