Introduction of Automatic Flood barrier/gate( also called Hydrodynamic automatic flood barrier)

Junli brand hydrodynamic automatic flood barrier/gate provides 7 × 24-hour water defensing and flood prevention protection. The flood gate is composed of a ground bottom frame, a rotatable water defense door leaf and a rubber soft stopping water plate at the ends of the walls on both sides. The whole flood gate adopt modular assembly and ultra-thin design which look like a the speed limit belt of vehicle. The flood gate can be quickly installed at the entrance and exit of underground buildings. When there is no water, the water defensing door leaf lies on the ground bottom frame, and the vehicles and pedestrians can pass through without obstacles; in case of flood, the water flows into the lower part of the water defensing door leaf along the water inlet at the front end of the ground bottom frame, and when the water level reaches the trigger value, the buoyancy pushes the front end of the water defensing door leaf to turn up, so as to achieve automatic water defense. This process belongs to pure physical principle, and does not need electric drive and no personnel on duty. It is very Safe and reliable. After the flood barrier deploying the flood defense door leaf, the warning light belt at the front of the water defensing door leaf flashes to remind the vehicle not to collide. Small water controlled circulation design, ingeniously solve the problem of slope surface installation. Before the arrival of flood, the flood gate can also be opened manually and locked in place.
