Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust devices, and in particular relates to an exhaust device for limited space operation on a ship. Background Art

[0002] Hot work is a common type of construction in the working space of shipbuilding and repairing enterprises, especially hot work such as carbon dioxide shielded welding and steel structure grinding in ship cabins. Hot work in the working space is also accompanied by the consumption of oxygen, the appearance of dust, carbon dioxide, and carbon monoxide, which makes ventilation in the working space particularly important. At present, the existing ventilation method at the production site of shipbuilding and repairing enterprises is to use a blower to transport external air into the working space through a duct.

[0003] In addition, because the structure of the ship's operating space is relatively complex, especially in the field of ship repair, the blower is generally installed on the deck, far away from the operating space, which has the disadvantage of air loss during transportation and limited ventilation efficiency.

[0004] The patent with publication number CN 218376949 U discloses a ship limited space operation exhaust device, including a blowing mechanism for conveying pure air into the operation space and an exhaust mechanism for exhausting the operation space, wherein the blowing mechanism and the exhaust mechanism are connected by a transmission mechanism; compressed air enters to provide pure air for the operation space; at the same time, the kinetic energy of the compressed air is utilized to drive the exhaust mechanism by a gear shaft to accelerate the discharge of the dirty air in the space, thereby improving the ventilation efficiency in the operation space. At the same time, the utility model is light in weight, convenient for on-site deployment, and convenient for use in small spaces. While ensuring ventilation efficiency, the exhaust device does not need to be driven by electricity, thereby eliminating the hidden danger of electrical safety caused by the provision of an electric fan, having higher safety performance and avoiding the risk of electrical injury.

[0005] The device requires compressed air during use, and air can only be supplied through an air tank. It occupies a large space, is not easy to move, and has a high cost of use. Utility Model Content
