Description
技术领域
本发明涉及电缆工井。
背景技术
电力电缆一般都安装在电缆沟道内，电缆沟道每隔一段距离均会铺设电力盖板方便后续维护。目前的电缆井盖板普遍采用钢筋混凝土材料，盖上后便无法直接查看沟内情况，必要时必须打开盖板，加大了电力电缆巡查的工作量，导致因防小动物巡视和维护检查不到位引起的事故时有发生。
现有技术的缺陷：(1)检修工作繁琐。(2)操作繁重。(3)不防盗。(4)撬起易损坏。
发明内容
本发明所要解决的技术问题就是提供一种电缆工井盖，方便电力电缆巡查，提高巡查和检修效率。
为解决上述技术问题，本发明采用如下技术方案：一种电缆工井盖，包括设于电缆工井口部的基架和设于基架上的透明基板，所述透明基板上开设有限位孔，所述基架上开设有固定孔，所述限位孔与固定孔匹配对接并穿过外接螺栓，所述基架上开设有防盗螺栓预留孔。
作为优选，所述透明基板包括上层钢化玻璃和下层钢化玻璃，两层钢化玻璃通过透明胶层贴合为一体，所述透明基板四周包覆有钢制边框。
作为优选，所述透明基板上开设有提拉钩槽。
作为优选，所述基架包括并排设置于电缆工井口部两侧的方钢，所述方钢的上侧外边缘焊接固定有挡边。
作为优选，所述钢制边框、基架的表面均涂覆有保护涂层。
作为优选，所述保护涂层包括环氧底漆和导热面漆，所述环氧底漆由环氧树脂、环氧树脂固化剂、溶剂、缩水干油醚稀释剂组成，所述溶剂由醚酯类溶剂、酮类溶剂、酯类溶剂、醇醚类溶剂组成，所述环氧底漆中各组分的重量百分比为环氧树脂20～30％、环氧树脂固化剂5～15％、醚酯类溶剂7～15％、酮类溶剂6～12％、酯类溶剂15～25％、醇醚类溶剂5～10％、缩水甘油醚稀释剂10～20％，所述导热面漆由为由A组分和B组分组成，所述A组分的重量百分比为聚氨酯树脂30～40％、丙烯酸树脂10～18％、导热填料20～30％、抗老化剂0.4～0.6％、分散剂0.8～1.2％、流平剂0.9～1.2％、防沉降剂1～1.5％、有机溶剂15～20％；所述B组分为脂肪族异氰酸酯的三聚体，所述A、B两组分混合重量比例20：1.4，混合方法将A组份充分搅拌，加入B组份，配漆后在25℃-35℃时熟化0.5-1.0小时再进行涂装。
作为优选，所述环氧底漆中各组分的重量百分比为环氧树脂26％、环氧树脂固化剂10％、醚酯类溶剂11％、酮类溶剂9％、酯类溶剂20％、醇醚类溶剂8％、缩水甘油醚稀释剂16％。
作为优选，所述缩水甘油醚稀释剂为聚乙二醇二缩水甘油醚、十二烷基缩水甘油醚、甲酚缩水甘油醚中的一种。
作为优选，所述醚酯类溶剂为丙二醇甲醚醋酸酯、乙二醇丁醚乙酸酯中的一种，酮类溶剂为丙酮、甲基丁酮、甲基异丁酮中的一种，酯类溶剂为醋酸甲酯、醋酸乙酯、醋酸丙酯中的一种，醇醚类溶剂为乙二醇单甲醚、乙二醇单乙醚、乙二醇单丁醚中的一种。
作为优选，所述A组分的重量百分比为聚氨酯树脂37％、丙烯酸树脂16％、导热填料25％、抗老化剂0.5％、分散剂1％、流平剂1％、防沉降剂1.5％、有机溶剂18％。
本发明采用透明盖板大大加强了电缆管沟的可视化程度，使得运行人员不掀开盖板就能掌握沟内电缆、支架、接地等设施状况，提高了电力电缆线路巡视的效率，为确保电缆线路安全运行提供了保障。另外，透明盖板约为同等设计要求混凝土盖板质量的一半，并自带提拉钩槽，避免了维护人员在需要对电缆沟道内的电力设施进行维护修理时利用铁撬施力对产品造成的损坏，结构简单且操作轻便，提高了维护检修效率，改善了维护人员的操作环境，降低了事故隐患的发生率。
附图说明
下面结合附图和具体实施方式对本发明作进一步描述：
