The invention provides a water tank drainage port for a submersible capable of avoiding backflow, and relates to the technical field of submersible. A water drainage hole is formed in the tank wall of the submersible water tank, the water drainage nozzle penetrates through the water drainage hole formed in the submersible water tank, and the edge of the inner end of the water drainage nozzle is bent outwards. A fastening coil is connected to the outer part of the drainage nozzle and is positioned outside the submersible water tank; the outer end of the drainage nozzle is sleeved with a stress supporting ring, and two bolts are connected into the stress supporting ring. When water stored in the submersible water tank stops flowing outwards, the movable push rod is reset under the thrust influence of the small spring, the rubber sealing plug makes contact with the outward side of the pore plate, the interior of the drainage nozzle is sealed through the rubber sealing plug, and the backflow condition is effectively avoided. The problems that the water outlet of the water tank for the submersible is poor in one-way sealing effect, and when the submersible dives to a deep water area, external water flows back into the water tank through the water outlet due to the fact that the submersible is prone to being affected by water pressure increase are solved.
本发明提供避免回流潜水器用水箱排水口,涉及潜水器技术领域,包括:潜水器水箱;所述潜水器水箱的箱壁上设置有排水孔,排水嘴贯穿于潜水器水箱所设有的排水孔内,排水嘴内端边缘呈向外弯折状;所述排水嘴外部连接有紧固螺圈,紧固螺圈位于潜水器水箱外部;所述排水嘴外端套装有受力支撑圈,受力支撑圈内连接有两个螺栓。本发明当潜水器水箱内部蓄水停止向外流通时,活动推杆受小弹簧推力影响下复位,使橡胶密封塞与孔板朝外一侧接触,通过橡胶密封塞对排水嘴内部进行密封,有效避免回流状况的发生。解决了潜水器用水箱排水口自身单向密封效果不佳,当潜水器下潜至较深水域时,容易受水压增大影响,导致外部水经排水口回流至水箱内的问题。
