Abstract

本实用新型涉及一种进人门防开装置，U型块卡在进人门座与进人门盖法兰侧面，通过螺栓预紧，实现U型块锁紧进人门座与进人门盖，钢片与U型块和螺栓点焊，防止螺栓松动。本实用新型优点是：1）高强度U型块受力面积大，不易破坏；2）高强度螺栓采用压应力预紧，螺栓不易被破坏；3）钢片与螺栓及U型块点焊，不但螺栓防松，而且螺栓松动易发现。4）结构简单，方便拆装，易推广。

Description

进人门防开装置
技术领域：本实用新型涉及一种进人门防开装置。
背景技术
目前，为安装、维修等方便，大中型水电机组在蜗壳、尾水管均设置进人门。进人门在机组运行过程中长期承受水压、机组振动等影响，其安全性直接关系到整个水电站厂房的安全，一直是电站运行维护人员的关注点。例如，某混流式机组多次发生蜗壳进人门多个螺栓断裂等问题，直接威胁到电站和工作人员的安全，使该电站意识到进人门防开的紧迫性和必要性。进人门螺栓断裂等问题的发生既隐蔽又危险，已引起业内人士极大重视。
发明内容
本实用新型的目的是提供一种能够有效提高进人门安全性的进人门防开装置。本实用新型是通过以下技术方案实现的：U型块卡在进人门座与进人门盖法兰侧面，通过螺栓预紧，实现U型块锁紧进人门座与进人门盖，钢片与U型块和螺栓点焊，防止螺栓松动。
本实用新型优点是：
1）高强度U型块受力面积大，不易破坏；
2）高强度螺栓采用压应力预紧，螺栓不易被破坏；
3）钢片与螺栓及U型块点焊，不但螺栓防松，而且螺栓松动易发现。
4）结构简单，方便拆装，易推广。
附图说明
图1为本实用新型的整体结构。
图2为本实用新型的布置形式。
具体实施方式
如图1所示的一种进人门防开装置，U型块1卡在进人门座4与进人门盖5法兰侧面，通过螺栓2预紧，实现U型块1锁紧进人门座4与进人门盖5，钢片3与U型块1和螺栓2点焊，防止螺栓松动。
