Description

technical field [0001] The invention relates to a safety device for ship construction, in particular to a multifunctional device capable of preventing falling at a manhole on the deck of a ship. Background technique [0002] There are many manhole covers arranged on the deck of the ship according to the functional requirements. During the construction of the ship, these manholes cannot be closed due to the construction work. How to prevent the construction personnel from falling into the cabin and at the same time provide ventilation and rain protection has become an important issue. solved problem. The traditional method is to take measures such as setting up temporary railings, placing warning signs, and covering construction workers in time after leaving the cabin. However, safety accidents still occur from time to time, and the consumption of manpower and material resources is also large. Contents of the invention [0003] The purpose of the present invention is to pr...
