Fireproof and cooling device and fireproof and cooling method of unmanned ship circuit system

Abstract

The present invention relates to a fireproof and cooling device and fireproof and cooling method of an unmanned ship circuit system. An existing fireproof and cooling method cannot applied to an unmanned ship and affects the security and normal work of the unmanned ship, and as a result, the potential risks of fires exist during a period when workers of an unmanned ship plant go out to work, while, with the device and method of the invention adopted, the defect of the existing method can be eliminated. The device includes a cooling box, a cooling pipe, an air nozzle, a cooling circulation device, a temperature sensor and a controller, wherein the cooling box is arranged in an electric equipment box and is used for accommodating cooling water for absorbing heat, the cooling pipe is arranged in the electric equipment box and is used for solidifying the cooling water, the air nozzle is connected with the cooling pipe, the cooling circulation device is connected with the cooling pipe and is used for circulating a cooling medium, the temperature sensor is arranged on the electric equipment box and is used for monitoring the temperature of the electrical equipment box, and the controller is connected with the temperature sensor and is used for controlling the cooling circulation device; the cooling medium solidifies the cooling water in the cooling box; after being solidified, the cooling water continuously releases cold energy to cool the electrical equipment box; and when the temperature exceeds a fire safety value, the liquid cooling medium is sprayed through the air nozzle, so that a fire prevention effect can be realized.

Description

technical field [0001] The invention belongs to the field of unmanned ship fire prevention safety, in particular to a fire prevention and cooling device and a fire prevention and cooling method for an unmanned ship circuit system. Background technique [0002] At present, when fire prevention and cooling of electrical equipment boxes are carried out on ships at home and abroad, most of the fire prevention requires human daily management and maintenance, and human operation is required for fire extinguishing. This is not feasible when the water sample collection unmanned ship goes out for a long time. [0003] In terms of cooling, water cooling or air cooling is mostly used. When water cooling is used, a water pump must be used to keep the cooling water in a low temperature state, and the water cooling effect is not very ideal. When a fire occurs, if water is used to extinguish the fire, it will be damaged. All electrical appliances in the electrical equipment box; when using...
