国家对海上风电的大力支持，使海上风电呈现出井喷式的发展，在海上风电快速发展的同时，也在面临着一系列新的问题，特别是海底电缆的损坏。据欧洲机构统计，目前海上风电海底电缆虽然故障率并非最高，但是海底电缆所造成的损失却已经占了很大的比重，海底电缆的保护已经成为亟需解决的问题。
目前国内外的海缆保护方式均采用分节哈夫结构，因结构或运输需要，每段长度大部分均控制为1米之内，安装费时费力，且成本高，此外因所需的连接件数量多，也在一定程度上增加了海缆的保护的故障率。
有鉴于此，如图1所示，为本申请实施例提供的海上风电基础海缆保护装置与基础海缆保护管I/J型管200及电缆300的连接结构示意图。图中，基础海缆保护管I/J型管200可以是从风力发电机基础中引出的，电缆300 从I/J型管200的一端穿入，从海上风电基础海缆保护装置100的另一端穿出。
如图2、图3和图4所示，为本申请实施例提供的海上风电基础海缆保护装置100，该海上风电基础海缆保护装置包括：连接法兰101、中间管体102、锥形连接管103和连接件104。
如图5所示，所述连接法兰101包括法兰盘1011和设置在所述法兰盘所在平面一侧的法兰连接管1012。本申请实施例中的海上风电基础海缆保护装置100可以应用于风力发电机的电缆保护，风力发电机产生的电能通过电缆300输送出去，风力发电机的电缆300一般通过风机基础上的“I”、“J”形管管道及深埋电缆的方式进行海缆保护，但由于海底冲刷等原因，造成电缆300悬空，在浪、涌的作用极易损坏。如采用本电缆保护方法，可将风机基础上的I/J型管通过法兰盘1011将连接法兰101与风机基础上的管道相连接，即使冲刷严重，也可将风力发电机内的电缆300保护在海上风电基础海缆保护装置100内部，有效防止电缆受损。
连接法兰101中法兰盘1011的大小和法兰连接管1012内径的大小可以根据电缆300的实际粗细进行设定。可以理解的是，本申请实施例提供的海上风电基础海缆保护装置100不仅可以应用在风力发电机的电缆保护中，还可以在其他需要进行电缆保护的场合使用。并且，海上风电基础海缆保护装置100不仅可以对不同的电力输送电缆进行保护，还可以对光缆等其他形式的线缆进行保护。
所述连接法兰101通过所述法兰连接管1012与所述中间管体102的一端相连接，所述中间管体102的另一端通过所述连接件104与所述锥形连 接管103相连接。连接法兰101的一端可以通过法兰盘1011与风机基础相连接，另一端通过法兰连接管1012与中间管体102相连接，本申请实施例中的中间管体102为中空管体，其具体长度可以根据实际使用需要进行调整。
如图3和图4所示，所述连接件104为两端开口的管体，所述连接件104的一端设置在所述中间管体102的另一端内部并与所述中间管体102固定连接，所述连接件104的另一端设置在所述锥形连接管103的一端内部并与所述锥形连接管103固定连接。本申请实施例中，连接法兰101与中间管体102的一端相连接，锥形连接管103通过连接件104与中间管体102的另一端相连接，这样即组成了整体的海上风电基础海缆保护装置100。
在实际施工使用中，可以在电缆上依次安装上锥形连接管103、连接件104、中间管体102和连接法兰101，这些组件的内径可以与实际的电缆300的直径相匹配，组装完成后将连接法兰101的法兰盘1011与风机基础上的管道相连接固定，即完成了海上风电基础海缆保护装置100的安装。如果需要不同长度的海上风电基础海缆保护装置100，可以增减中间管体102的长度，以方便使用。还可以将两个海上风电基础海缆保护装置100的两端的法兰盘1011相连接，组成长度更长的海上风电基础海缆保护装置100。
进一步的，所述法兰连接管1012远离所述法兰盘1011的一端的外径与所述中间管体102一端的内径相匹配，所述法兰连接管1012远离所述法兰盘1011的一端设置在所述中间管体102一端内并与所述中间管体102固定连接。
本申请实施例中的连接法兰101在与中间管体102相连接时，可以将法兰连接管1012插入到中间管体102内，优选的，可以将法兰连接管1012的外径设置成等于中间管体102的内径，为了方便安装，也可以将法兰连接管1012的外径设置成稍小于中间管体102的内径，在安装时，外径小于或者等于中间管体102内径的法兰连接管1012就可以进入到中间管体102内，再通过其他组件完成两者的固定连接。
进一步的，如图5和图6所示，所述法兰连接管1012开设有多个第一通孔1013，所述中间管体102上开设有与所述第一通孔1013相匹配的第二通孔1021，所述第一通孔1013和所述第二通孔1021通过第一紧固件105连接将所述连接法兰101和中间管体102固定连接。第一通孔1013的开设位置可以在法兰连接管1012上的任意位置，开孔数量可以根据需要确定，一般情况下，第一通孔1013开始在法兰连接管1012远离法兰盘1011的一端，并且在法兰连接管1012的一个横截平面上，开设多个第一通孔1013。中间管体102上第二通孔1021的开设位置可以根据第一通孔1013开设位置确定，由于在安装使用中，法兰连接管1012可以全部进入到中间管体102内部，中间管体102的端部可以与法兰盘1011接触。
为了将中间管体102和法兰连接管1012相固定，所述第一通孔1013内设有螺纹，所述第一紧固件105包括多个第一螺栓1052和第一夹片1051，所述第一夹片1051与所述中间管体102的横截面形状相匹配，所述第一夹片1051设置在所述中间管体102外，所述第一螺栓1052与所述第一通孔1013螺旋配合将所述第一夹片1051固定在所述中间管体102外。第一通孔1013和第二通孔1021的大小可以开设成相同大小的通孔，并且他们的位置 相匹配，并在第一通孔内预先设置螺纹。第一夹片1051的形状与中间管体102横截面形状相匹配，可以设置成一个圆环，为了方便安装还可以设置成圆环的一部分，可以通过多个第一夹片1051完成固定连接。
第一夹片1051上也开设有通孔，在进行法兰和中间管体102的连接安装时，将法兰连接管1012插入到中间管体102内部，将第一通孔1013和第二通孔1021的位置对齐，然后在中间管体102的设置第一夹片1051，并保证第一夹片1051上的通孔位置和第一通孔1013、第二通孔1021的位置也对齐，再使用型号匹配的第一螺栓1052，从第一夹片1051外螺旋进入到第二通孔1021，最后进入法兰连接管1012上的第一通孔1013。一般情况下，第一通孔1013和第二通孔1021的数量一致，并且所有第一夹片1051上的通孔的数量也与第一通孔1013的数量相同。在将第一螺栓1052全部通过第一夹片1051上的通孔进入到第一通孔1013后，这样就完成了第一夹片1051、中间管体102和法兰连接管1012的连接。即将连接法兰101和中间管体102连成了一体。
进一步的，所述连接件104的一端开设有多个第三通孔1041，另一端开设有多个第四通孔1042，所述中间管体102上开设有与所述第三通孔1041相匹配的第五通孔1022，所述第三通孔1041和第五通孔1022通过第二紧固件106将所述中间管体102和连接件104固定连接。
由于连接件104的两端分别设在中间管体102和锥形连接管103的内部，在进行相关的固定连接时可以设置成与上述第一紧固件105相似的形式。一般情况下连接件104的长度要小于中间管体102的长度，使连接件104在实现连接作用的同时也不会由于长度过长影响制造成本。在本申请实 施例中，完成连接件104分别和中间管体102、锥形连接管103的连接后，连接件104就全部进入到了海上风电基础海缆保护装置100的内部，中间管体102的端部和锥形连接管103的端部相接触。
另外，所述锥形连接管103上开设有与所述第四通孔1042相匹配的第六通孔1031，所述第四通孔1042和第六通孔1031通过第三紧固件107将所述连接件104和所述锥形连接管103固定连接。
在本申请实施例中，如图7所示，所述锥形连接管103包括圆柱管部分1032和锥形管部分1033，所述锥形管部分1033包括大端部和小端部，所述大端部和小端部的内径不同，所述大端部的一端与圆柱管部分1032相连接，所述小端部的内径与需要保护的电缆300的外径相匹配，所述圆柱管部分1032远离所述锥形管部分1033的一端的内径与所述连接件104的外径相匹配。锥形连接部包括形状不同的两部分，圆柱管部分1032主要实现与连接件104的连接，锥形管部分1033设置成了锥台的形状，即锥形管部分1033的竖切剖面是一个外部呈梯形的形状，这样电缆在安装进入到海上风电基础海缆保护装置100后，小端部可以与电缆300的外壳相接触，保证其他杂物不会进入到海上风电基础海缆保护装置100内部。小端部的内径可以等于电缆300的外径，也可以稍小于电缆300的外径，以防止杂物或海生物进入。
优选的，所述第六通孔1031开设在所述圆柱管部分1032远离所述锥形管部分1033的一端。
另外，所述第三通孔1041、第四通孔1042设有螺纹，所述第二紧固件106包括多个第二螺栓1062和第二夹片1061，所述第二夹片1061与所述 中间管体102的横截面形状相匹配，所述第二夹片1061设置在所述中间管体102外，所述第二螺栓1062与所述第三通孔1041螺旋配合将所述第二夹片1061固定在所述中间管体102外，以使所述中间管体102与所述连接件104固定连接。
与第一紧固件105的设置方式类似，这里第二紧固件106也是通过第二夹片1061和第二螺栓1062完成第三通孔1041和第五通孔1022的连接。在安装使用时，将连接件104开设第三通孔1041的一端放入到中间管体102开设第五通孔1022的一端内部，将第三通孔1041和第五通孔1022对齐，然后在中间管体102外与第五通孔1022的位置布置第二夹片1061，最后使用与通孔匹配的第二螺栓1062，依次通过第二夹片1061上的通孔、第五通孔1022和第三通孔1041，将所有通孔全部旋紧安装第二螺栓1062后，即完成了连接件104与中间管体102的连接。
同样的，所述第三紧固件107包括多个第三螺栓1072和多个第三夹片1071，所述第三夹片1071与所述圆柱管部分1032的横截面形状相匹配，所述第三螺栓1072与所述第四通孔1042、第六通孔1031螺旋配合将所述第三夹片1071固定在所述锥形连接管103外，以使所述连接件104与所述锥形连接管103固定连接。
在连接件104和锥形连接头的固定过程中，同样先将连接件104放入到锥形连接头内部，并将第四通孔1042和第六通孔1031对齐，在锥形连接头外设置好第三夹片1071，使第三夹片1071上的通孔与第六通孔1031对齐，再使用第三螺栓1072将第四通孔1042、第六通孔1031和第三夹片1071上的通孔螺旋连接。在完成所有第三螺栓1072的安装后，即完成了连 接件104与锥形连接头的固定连接。本申请实施例中的第一紧固件105、第二紧固件106和第三紧固件107可以使用相同规格的夹片和螺栓，第一夹片1051、第二夹片1061和第三夹片1071的规格相同，都与如图8所示的第一夹片的结构相同。
综上所述，使用本申请实施例提供的海上风电基础海缆保护装置100，结构简单，制造过程中无需分段开模，降低了海上风电基础海缆保护装置100的生产成本。在安装使用过程中，可以根据实际需要增减中间管体102的长度，整体安装简便，能够快捷高效的完成海上风电基础海缆保护装置100的组装工作，提高海上风电基础海缆保护装置100实际使用的安装效率，减少相关安装工作时长和工作量。并且，可以通过连接法兰101与风力发电机上的电缆管道相连接，实现对风力发电机输出电缆的保护。
