Description

一种可拆卸式防雨罩 技术领域
本实用新型涉及电力设备技术领域，尤其涉及一种可拆卸式防雨罩。
背景技术
绝缘操作杆是10千伏及以上输配电线路班组日常工作中最常用到的一种作业器具，被广泛应用于10千伏及以上输配电线路开关及跌落式熔断器设备停送电操作中。绝缘棒是电力部门开展电力设备倒闸操作最重要的工器具，但遇到雨天，雨水将绝缘棒浸湿，绝缘性能下降，操作人员存在触电的安全隐患，必须停止操作，由此造成电力设备的相关检修、施工作业也被迫停止，电力网络的供电可靠性大幅度下降。
为了能在下雨天倒闸操作，安全规程里要求必须使用带有防雨罩的绝缘棒。目前常用的防雨罩有以下缺点：
1、长期固定式的防雨罩，在使用过程中，防雨罩不可收缩以及拆卸，容易被挤压和被异物钩破，失去防雨的功能，在雨天操作时容易导致触电事故发生。
2、现有的可拆卸绝缘棒防雨罩，由于防雨罩的形状固定，不能根据绝缘棒直径大小进行调节，因此难以适应不同直径大小的绝缘棒，通用性差。
实用新型内容
本实用新型为解决现有用于绝缘棒的防雨罩存在拆卸不便、大小不可调节等问题，提供了一种可拆卸式防雨罩。
为实现以上实用新型目的，而采用的技术手段是：
一种可拆卸式防雨罩，包括伞状防雨罩本体、滑块和若干可伸缩支架，所述伞状防雨罩本体的顶端开设通孔，用于套设在绝缘棒上从而与绝缘棒连接；所述伞状防雨罩本体设有纵向的开口，开口的两侧可拆卸连接；所述可伸缩支架的一端与所述伞状防雨罩本体的内侧面连接，所述可伸缩支架的另一端与滑块连接，所述滑块用于与绝缘棒滑动连接，所述滑块上设有开合机构。上述方案中，由于用于与绝缘棒固定连接的伞状防雨罩本体和滑块均可进行开合，伞状防雨罩本体的伸缩状态可通过滑块对可伸缩支架调整从而改变，使得防雨罩方便收缩和拆装。
优选的，所述伞状防雨罩本体顶端的通孔处向上延伸形成一连接部，所述连 接部用于套设在绝缘棒上从而与绝缘棒连接。在本优选方案中，通过连接部与绝缘棒紧密贴合，防止防雨罩顶部与绝缘棒的连接位置进水，进一步提高绝缘性能。
优选的，所述伞状防雨罩本体开口的两侧设有魔术贴。在本优选方案中，解开开口两侧的魔术贴即可打开伞状防雨罩本体的开口，粘贴上开口两侧的魔术贴即可闭合伞状防雨罩本体的开口，使得防雨罩的拆装操作更为简单方便。
优选的，所述伞状防雨罩本体开口的两侧设有拉链。在本优选方案中，拉开开口两侧的拉链即可打开伞状防雨罩本体的开口，拉上开口两侧的拉链即可闭合伞状防雨罩本体的开口，使得防雨罩的拆装操作更为简单方便，并且拉链结构的连接更为牢固。
优选的，所述滑块为C形弹性卡扣。在本优选方案中，C形弹性卡扣可以实现在一定范围都具有卡紧性能，从而适应于不用直径大小的绝缘棒，使得防雨罩具有更高的通用性。
优选的，所述可伸缩支架包括第一连接杆、第二连接杆和第三连接杆，所述第一连接杆的一端与所述伞状防雨罩本体的内侧面连接，所述第一连接杆的另一端与所述第二连接杆的一端铰接，所述第二连接杆的另一端与所述第三连接杆的一端铰接，所述第三连接杆的另一端与所述滑块连接。在本优选方案中，当滑块沿着绝缘棒靠近伞状防雨罩本体的方向移动，推动第一连接杆、第二连接杆和第三连接杆的铰接处翻转，使伞状防雨罩本体撑开，反之使伞状防雨罩本体收起，方便地实现防雨罩的伸缩，以及根据使用需要调整伞面的大小。
优选的，所述伞状防雨罩本体采用弹性绝缘布。在本优选方案中，伞状防雨罩本体采用弹性绝缘布，起到绝缘作用的同时，由于具有一定弹性，其连接部可以适应于一定直径范围内的绝缘棒，使得防雨罩的通用性更好，同时起到更好的绝缘防护作用。
优选的，所述滑块和若干可伸缩支架均为塑料材质。在本优选方案中，滑块和可伸缩支架采用塑料材质，进一步提高绝缘性。
优选的，所述可伸缩支架共有三组，且三组可伸缩支架等间隔设置。在本优选方案中，三组可伸缩支架等间隔设置对防雨罩本体起到更好的支撑效果，同时简化防雨罩的结构。
优选的，所述伞状防雨罩本体上设有若干纵向折痕。在本优选方案中，伞状防雨罩本体收缩后沿折痕折叠，防雨罩的收纳更为方便。
与现有技术相比，本实用新型技术方案的有益效果是：
本实用新型的可拆卸绝缘棒防雨罩中，由于用于与绝缘棒固定连接的伞状防雨罩本体和滑块均可进行开合，伞状防雨罩本体的伸缩状态可通过滑块对可伸缩支架调整从而改变，使得防雨罩方便收缩和拆装。防雨罩中与绝缘棒固定连接的连接部以及滑块均可以适应于一定直径范围内的绝缘棒，提高了本实用新型的通用性并起到更好的绝缘效果。由于滑块可以固定在绝缘棒的任意位置，配合可伸缩支架可以对伞状防雨罩本体的展开大小进行调整从而适应不同的遮挡需求。
本实用新型的可拆卸绝缘棒防雨罩晴天可拆卸保存，雨天即时安装应用，能更有效的避免被异物钩破的可能性，解决了现有用于绝缘棒的防雨罩存在拆卸不便、大小不可调节等问题。本实用新型结构简单，易于实现。
