[0002] In firefighting and rescue work, a large amount of firefighting foam needs to be sprayed on the fire scene to extinguish the fire. The traditional way of transmitting firefighting foam mainly relies on fire trucks, which requires the fire trucks to be driven close to the fire scene before they can be used. In addition, the fire pump needs to lay pipelines, which is complicated to operate. To solve this problem, a portable firefighting foam transmission device came into being. This device mainly includes a portable pump body and a quick-connect pipe interface. The pump body can suck in firefighting foam and transmit it quickly. The quick interface can be quickly connected to the storage tank and the spraying accessories. The whole system is easy to carry and can be quickly deployed without the fire truck approaching.
