Temporary manhole channel door cover for ship
The invention discloses a temporary manhole channel door cover for a ship. The cover comprises an annular supporting piece, a rotating component, a first inclined supporting piece and a second inclined supporting piece, and the rotating component comprises a first rotating piece, a second rotating piece, a rotating shaft and a first connecting block. According to the temporary manhole channel doorcover for the ship, the first and second inclined supporting pieces form a net-shaped structure, the mass of the temporary manhole channel door cover for the ship is greatly reduced while the step missing problem is solved, and therefore convenience is provided for operation; besides, the temporary manhole channel door cover for the ship is further rotationally connected with the channel door ring through a rotating part; when the marine temporary manhole channel door cover is opened and closed, only a buckling part needs to be controlled, the annular supporting piece, the first inclined supporting piece and the second inclined supporting piece serve as a whole and rotate to the needed degree relative to the channel door ring, and therefore it is not required to detach the whole marine temporary manhole channel door cover, and operation is simplified. Therefore, the defect that the bulky original manhole channel door cover is repeatedly disassembled and assembled in order to prevent step missing during operation is overcome.
本发明公开了一种船用临时人孔道门盖，包括环形支撑件、转动部件、第一斜撑件以及第二斜撑件，其中，转动部件包括第一转动件、第二转动件、转轴以及第一连接块。本发明通过第一斜撑件和第二斜撑件形成网状结构，在解决踏空问题的同时极大降低了船用临时人孔道门盖的质量，从而为操作提供了方便；另外，船用临时人孔道门盖还通过转动部件与道门圈转动连接，在开、合时只需要控制扣动部，使得环形支撑件、第一斜撑件及第二斜撑件作为一个整体相对于道门圈旋转至需要的程度即可，因而不需要拆下整个船用临时人孔道门盖，简化了操作；故本发明克服了作业期间为防止踏空而反复拆装笨重的原人孔道门盖的缺陷。
