Description

一种可伸缩的铅钢复合防护门槛
技术领域
本实用新型涉及射线防护设施技术领域,具体是一种可伸缩的铅钢复合防护门槛。
背景技术
射线是由各种放射性核素发射出的、具有特定能量的粒子或光子束流,反应堆工程中常见的有的射线、射射线、γ射线和中子射线,各种射线,由于电离密度不同,生物效应是不同的,所引起的变异率也有差别,为了获得较高的有利突变,必须选择适当的射线,但由于射线来源、设备条件和安全等因素,目前最常用的是γ射线和x射线。
现有的放射机房防护门均采用无门槛方式安装,在控评检测验收时,门下沿与地面缝隙漏射线验收不合格,为满足机房放射防护验收要求,需要在门口处进行防护处理,因此,本实用新型提出一种可伸缩的铅钢复合防护门槛来解决上述问题。
实用新型内容
本实用新型的实施例目的在于提供一种可伸缩的铅钢复合防护门槛,以解决上述问题。
为实现上述目的,本实用新型提供如下技术方案:
一种可伸缩的铅钢复合防护门槛,包括外固定壳体和内伸缩壳体,所述外固定壳体内腔底部固定设有伸缩轨道,内伸缩壳体通过伸缩轨道滑动设于外固定壳体内,外固定壳体和内伸缩壳体内壁上均固定贴设有与机房门防护当量一致的铅板,外固定壳体和内伸缩壳体均由不锈钢装饰面板制成。
相较于现有技术,本实用新型实施例的有益效果如下:
1、该防护门槛解决了防护门缝漏射线的问题,其技术既能满足整体机房的防护检测要求,又达到国家控评验收标准,非常具有实用意义。
附图说明
图1为本实用新型实施例的结构示意图。
附图标记注释:1-外固定壳体、2-内伸缩壳体、3-伸缩轨道、4-铅板。
具体实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本实用新型进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本实用新型,并不用于限定本实用新型。
实施例1
请参阅图1,本实用新型实施例中,一种可伸缩的铅钢复合防护门槛,包括外固定壳体1和内伸缩壳体2,所述外固定壳体1内腔底部固定设有伸缩轨道3,内伸缩壳体2通过伸缩轨道3滑动设于外固定壳体1内,外固定壳体1和内伸缩壳体2之间可根据实际安装点要求自由伸缩以调节整体长度,外固定壳体1和内伸缩壳体2内壁上均固定贴设有与机房门防护当量一致的铅板4,以达到全方位无死角防止射线外漏的目的。
进一步的,外固定壳体1和内伸缩壳体2均由不锈钢装饰面板制成,既达到放射防护的检测标准,又满足装饰装修的使用要求。
本实用新型的工作原理是:本实用新型先在车间内加工成品,再运送至现场进行安装,在安装时,先通过结构胶将外固定壳体1固定粘接在地面上,然后根据防护门实际尺寸长短拉动内伸缩壳体2进行调节并粘接固定,即可达到全方位无死角防止射线外漏的目的。
以上所述仅为本实用新型的较佳实施例而已,并不用以限制本实用新型,凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本实用新型的保护范围之内。
