Description

核电厂人员闸门缓冲装置 技术领域
本发明属于核电领域，更具体地说，本发明涉及一种核电厂人员闸门缓冲装置。
背景技术
核电厂人员闸门的主要功能是供人员和小型设备在反应堆运行或热停堆时通过，而不损坏安全壳的密封功能。特殊情况下还具备以下功能：事故工况下，作为人员紧急撤离的出口；在冷停堆时，闸门解除连锁，内外门同时开启，可以作为人员和小型设备进出安全壳的通道；在安全壳进行密封和强度试验时，可作为增压/减压舱。
人员闸门结构包括筒体、密封门(内、外两扇)、升降门阶、通道底板等结构，并包含驱动这些结构的传动机构、联锁机构、压力平衡机构、锁紧机构、外门铰链机构、内门铰链机构、顶升机构。人员闸门密封门关闭过程中，门板以一定的速率旋转闭合，在门板与门框接触的一瞬间，存在较大的反弹力及反弹位移。现有的缓冲机构不能充分缓冲门板的冲击力，引起密封门反弹，导致人员闸门密封门关闭后密封不严密。同时，密封门关闭时的瞬时反弹冲击影响传动机构的使用寿命。由于人员闸门属于核安全壳承压边界的一部分，贯穿于内外安全壳，密封门的关闭不严密有可能导致核安全壳承压边界的失效，造成严重的后果。
有鉴于此，确有必要提供一种核电厂人员闸门缓冲装置，保证人员闸门密封门的正常关闭，维护安全壳承压边界的完整性。
发明内容
本发明的目的在于：克服现有缓冲装置缓冲能力的不足，提供一种核电厂人员闸门缓冲装置，保证人员闸门密封门的正常关闭，维护安全壳承压边界的 完整性。

为了使本发明的目的、技术方案及其技术效果更加清晰，以下结合附图和具体实施方式，对本发明进行进一步详细说明。应当理解的是，本说明书中描述的具体实施方式仅仅是为了解释本发明，并非为了限定本发明。
请参阅图1至图4所示，本发明核电厂人员闸门缓冲装置包括：
吸盘结构件12，固定在门框20上，包括固定连接的电磁吸盘120和吸盘垫板122，吸盘垫板122的两侧设置有滑板124，连接在一起的电磁吸盘120和吸盘垫板122能够沿着滑板124上下移动，电磁吸盘120连接有电源(图未示出)，用于对电磁吸盘120的供电时间进行控制；以及
吸板结构件14，固定在门板30上，包括吸板140、吸板连接板142和门板连接板144，吸板140固定在吸板连接板142上，吸板连接板142和门板连接板144之间设置有第一弹簧146，第一弹簧146内部穿设有第一芯轴148，第一芯轴148一端与吸板连接板142固定，另一端穿过门板连接板144后通过辅助件将第一弹簧146设置在吸板连接板142和门板连接板144之间；
其中，吸盘结构件12和吸板结构件14可进行吸合锁紧和开启。
请参阅图1和图2所示，吸盘结构件12通过螺栓、焊接、粘接、结构嵌套或卡箍固定在门框20上，在图示实施方式中，吸盘结构件12通过螺栓可拆卸固定在门框20上，电磁吸盘120为现有技术中常用的吸盘，如家用门禁系统的电磁吸盘，内部设置有线圈，用于通电产生磁力，将接触在电磁吸盘120表面 的吸板140紧紧吸住，通过线圈断电，磁力消失实现退磁，在图示实施方式中，电磁吸盘120为长方体结构，表面为平面结构。
吸盘垫板122为一块长方形薄板，位于电磁吸盘120的下部，并通过螺栓、焊接、粘接、嵌套或卡箍与电磁吸盘120固定连接，在图示实施方式中，吸盘垫板122通过螺栓与电磁吸盘120固定连接。吸盘垫板122的两侧设置有导轨1220。
滑板124设置有两个，主要用于解决门体关闭时竖向移动问题，位于吸盘垫板122的两侧，滑板124的上端设置有上部挡板126，滑板124的下端设置有下部挡板128，吸盘垫板122的下面设置有第二弹簧130，第二弹簧130内部穿设有第二芯轴132，第二芯轴132一端与吸盘垫板122通过焊接固定连接，另一端穿过下部挡板128，并可上下移动，第二弹簧130位于吸盘垫板122和下部挡板128之间。
具体地，滑板124为具有一定厚度的长条形板，其长度大于吸盘垫板122和电磁吸盘120的长度，两个滑板124对称位置开设有螺栓孔，通过螺栓固定在门框20上，最终实现将整个吸盘结构件12固定在门框20上。上部挡板126和下部挡板128也为长条形板，尺寸可相同，也可不相同，优选相同，上部挡板126和下部挡板128的厚度与滑板124的厚度基本上相同，并通过螺栓与滑板124可拆卸固定连接，固定连接后，上部挡板126和下部挡板128的端部与滑板124的边部平齐。
实施例1
请参阅图2所示，滑板124的厚度大于吸盘垫板122的厚度，滑板124位于吸盘垫板122的一侧设置有滑槽1240，滑槽1240最好位于滑板124厚度方向的中部位置，并延伸至两端，吸盘垫板122的两侧设置有导轨1220，导轨1220位于吸盘垫板122的上部，且导轨1220的厚度略小于滑槽1240的宽度，两侧的导轨1220分别嵌入两侧滑板124的滑槽1240中，并沿滑槽1240轴向移动。
吸盘垫板122的两侧由于设置有导轨1220，吸盘垫板122的宽度要大于相 邻两个滑板124之间的间距，确保吸盘垫板122沿着滑槽1240上下移动时不会从滑槽1240脱落。同时，吸盘垫板122的底部高于滑板124的底部，保持与底部的门框间存在间隙，以便滑动。电磁吸盘120通过螺栓固定在吸盘垫板122上后，电磁吸盘120的宽度略小于相邻两个滑板124之间的间距，确保电磁吸盘120与吸盘垫板122的整体能够在相邻两个滑板124的滑槽中上下移动。
实施例2
滑板124与吸盘垫板122相邻的一侧设置有凹槽轴承(图未示出)，具体地，在滑板124上通过安装支架间隔设置一些凹槽轴承，然后通过在吸盘垫板122的两侧设置导轨(图未示出)，两侧的导轨分别位于凹槽轴承(图未示出)的凹槽中，吸盘垫板122通过两侧的导轨与凹槽轴承适配，可实现轴向移动。
同时，也可在滑板124与吸盘垫板122相邻的一侧开设一些安放凹槽轴承的槽口(图未示出)，利用固定轴(图未示出)将凹槽轴承(图未示出)固定在槽口内，并且凹槽轴承可以在槽口内转动，然后通过在吸盘垫板122的两侧设置导轨(图未示出)，两侧的导轨分别位于凹槽轴承(图未示出)的凹槽中，吸盘垫板122通过两侧的导轨与凹槽轴承适配，可实现轴向移动。
实施例3
实施方式3与实施方式2基本相同，不同之处在于，在吸盘垫板122的两侧设置凹槽轴承(图未示出)，滑板124与吸盘垫板122相邻的一侧设置导轨(图未示出)，导轨位于凹槽轴承的凹槽中，吸盘垫板122通过凹槽轴承和导轨可进行轴向移动。
凹槽轴承(图未示出)可通过安装支架间隔固定在吸盘垫板122的两侧，也可通过在吸盘垫板122的两侧设置槽口，并通过固定轴安放凹槽轴承，具体设置方式与实施方式2相同。
第二芯轴132的一端焊接或通过螺纹连接固定在吸盘垫板122的底部，在图示实施方式中，并排设置有两根第二芯轴132，并对称焊接固定在吸盘垫板122的底部，第二芯轴132为圆柱形结构，每根第二芯轴132上套设有一个第二弹簧130。在本发明的其他实施方式中，第二芯轴132的数量也可根据需要 进行调整。下部挡板128上对应两根第二芯轴132的位置设置有两个通孔，第二芯轴132一端焊接在吸盘垫板122底部后，另一端从通孔伸出，当电磁吸盘120和吸盘垫板122固定后的整体上下移动时，第二芯轴132可在通孔内自由上下移动。
第二弹簧130穿设在第二芯轴132上，并位于吸盘垫板122底部和下部挡板128之间，第二弹簧130松弛状态时的长度等于或略大于吸盘垫板122底部到下部挡板128上部的高度。当密封门门板30与门框20接触关闭后，需要整体向下滑动，第二弹簧130用于竖向滑动的缓冲及密封门开启后的复位，第二芯轴132用于吸盘垫板122和电磁吸盘120固定后的整体上下滑动时定位，吸盘结构件12在第二弹簧130上压缩后的行程不低于门板30运动的行程。
请参阅图3和图4所示，吸板结构件14通过螺栓、焊接、粘接、结构嵌套或卡箍固定在门板30的边部，在图示实施方式中，吸板结构件14通过螺栓可拆卸固定在门板30的边部，主要通过在门板连接板144上开设螺栓孔，然后通过螺栓固定在门板30上，最终将整个吸板结构件14固定在门板30上。
吸板140和吸板连接板142通过螺栓、焊接、粘接、嵌套或卡箍进行固定，在图示实施方式中，吸板140和吸板连接板142通过螺栓可拆卸固定连接，吸板140为一块与电磁吸盘120大小适配的平面板，当密封门关闭时，吸板140与电磁吸盘120吸合，并且吸板140与电磁吸盘120刚好匹配。吸板连接板142为一块长方形板，长度和宽度均大于吸板140，吸板140通过螺栓固定在吸板连接板142的中心，固定后吸板140两端距离吸板连接板142两端各有一段距离，且距离相等。
门板连接板144为一块方形板，其宽度大于吸板连接板142的宽度，其长度与吸板连接板142的长度基本上一致。
门板连接板144的一侧设置有固定孔，另一侧设置有螺栓孔，一侧的固定孔用于插入第一芯轴148，另一侧的螺栓孔用于插入螺栓与门板30固定，在图示实施方式中，门板连接板144通过螺栓固定在门板30的边部。第一芯轴148 的一端连接在吸板连接板142上，另一端穿过门板连接板144的固定孔后通过辅助件连接。第一芯轴148上套设有第一弹簧146，第一弹簧146套设在第一芯轴148上后，位于吸板连接板142和门板连接板144之间，用于起缓冲作用。在图示实施方式中，辅助件为螺母150，第一芯轴148为螺栓，一端连接在吸板连接板142上，另一端穿过门板连接板144的固定孔后通过螺母150连接，将第一弹簧146夹设在吸板连接板142和门板连接板144之间，用于限定第一弹簧146的伸缩，并进一步限定吸板连接板142和门板连接板144之间的距离。在本发明的其他实施方式中，第一芯轴148穿过门板连接板144的固定孔后的一端设置有插销孔，一端连接在吸板连接板142上，有插销孔的一端穿过门板连接板144的固定孔后通过插设插销将第一弹簧146夹设在吸板连接板142和门板连接板144之间。
请参阅图3和图4所示，第一弹簧146用于水平冲击缓冲，当门板30关闭时会以一定的速率向门框20旋转冲击关闭，缓冲装置能够充分吸收该部分动能。因此，在设计时，缓冲装置装配后，门板连接板144底面到滑板124底面的距离(即门板连接板144底面距离门框20的距离)大于门板30的厚度，以便在门板30与门框20未接触时可以开始缓冲，到接触时冲击力已经降低，可充分吸收门板30的冲击力。
另外，缓冲过程中对电磁吸盘120通电，吸盘结构件12与吸板结构件14吸紧贴合，可限制门板30反弹位移。
由于吸板结构件14设计有第一弹簧146进行压缩缓冲，在门板30开启后，吸板结构件14能够迅速复位，不会影响再次使用。由于吸盘垫板122下面设置有第二弹簧130进行压缩缓冲，在密封门门板30开启后，电磁吸盘120和吸盘连接板122连接后的整体也能够迅速复位，不影响吸盘结构件12的再次使用。
同时，通过对电源开关进行控制，实现对电磁吸盘120的供电时间进行控制，在密封门门板30与门框20接触前或接触时，对电磁吸盘120通电，实现电磁吸盘120与吸板140吸紧贴合，在电磁吸盘120与吸板140吸紧一段时间(该 时间不超过闸门竖向滑动总时间)后，断开电源，此时电磁吸盘120无吸力，人员闸门密封门门板30可继续回落运动。同时，电磁吸盘120是电子产品，若长期处于通电状态，影响其使用寿命，在门板30关闭到位后对电磁吸盘120实行断电处理，不影响其使用寿命。
相对于现有技术，本发明核电厂人员闸门缓冲装置具有以下有益技术效果：
1)结构简单，设计方便；
2)解决了人员闸门密封门关闭时的水平冲击力过大引起的反弹力及反弹位移问题，使人员闸门密封门能够正常关闭，保证了闸门设备的密封性，维护了核安全壳承压边界的完整性；
3)解决了人员闸门密封门与门框贴合的竖向滑动问题，降低了原有缓冲装置的摩擦磨损问题。
根据上述原理，本发明还可以对上述实施方式进行适当的变更和修改。因此，本发明并不局限于上面揭示和描述的具体实施方式，对本发明的一些修改和变更也应当落入本发明的权利要求的保护范围内。此外，尽管本说明书中使用了一些特定的术语，但这些术语只是为了方便说明，并不对本发明构成任何限制。
