The out-of-box fire water module 133 is located at the top end of the fire-proof and explosion-proof wall 14, and carries out-of-box temperature reduction and fire extinguishment on the containers 2 in the fire-proof box array. Wherein, the length, thickness and height of each side of the fireproof and explosion-proof wall 14 meet the relevant national fire-fighting standards. Compared with the arrangement scheme of the containers 2 without the fireproof explosion-proof walls 14, the arrangement mode that one container 2 corresponds to one foundation arrangement requires that the arrangement interval of the containers 2 is not less than 3m under the condition of meeting the safety fireproof interval condition and the installation and maintenance requirement, so that the total occupied area of the power station is larger. And the scheme of adopting the fireproof explosion-proof wall 14 is not limited by 3 m.

With continued reference to fig. 2 and 3, in one embodiment of the present invention, the outside fire water module 133 optionally includes a spray head 1331 and a second type of electrically operated valve (not shown in fig. 1 and 2). Illustratively, the second type of electric valve is located at the bottom of the nozzle 1331, or the second type of electric valve is built into the nozzle 1331. Wherein, the spray head 1331 is positioned at the top end of the fireproof and explosion-proof wall 14; the second type of electric valve is located between the nozzle 1331 and the fire hose network 134, and is in communication connection with the fire main control device 11. In the embodiment of the invention, the fire-fighting main control device 11 is in butt joint with the second type of electric valves, so that the opening states of the second type of electric valves can be acquired and the second type of electric valves can be controlled to be opened and closed. Therefore, in the embodiment of the invention, after the fire extinguishing main machine 12 in the box carries out gas fire extinguishing, the opening of the second type electric valve can be controlled in time according to needs, and the temperature reduction fire extinguishing outside the box is carried out.

Wherein, it is different with the inside conflagration condition of container that first fire detector in the waterproof module of incasement disappears, and the conflagration condition at container top is detected to the second fire detector. Therefore, when fire water submerges, the first fire detector is also submerged by the fire water, the fire situation cannot be detected, and the real situation of the fire can be judged through the second fire detector. The second fire detector is abnormal, namely, the second fire detector continuously sends out a fire alarm, so that the fire is not extinguished, and the step of fire water flooding needs to be continuously executed. The second fire detector normally means that the fire alarm is not issued, i.e., the fire is suppressed, and the operation of extinguishing the fire can be ended.
