The invention provides a pressure balance type underwater toilet blowdown device, belongs to the technical field of blowdown devices, and aims at solving the problem that an existing submarine underwater toilet is poor in use effect. The device comprises a storage barrel, a piston and a push rod; the storage barrel comprises a barrel body and two end covers; the two end covers are fixed to the two ends of the barrel body respectively; the piston is movably arranged in the barrel body; and one end cover is provided with a through hole for containing the push rod, one end of the push rod penetrates through the through hole and extends into the barrel body, and the push rod is fixedly connected with the piston. According to the design, compressed air is not used as a pollution discharge mode, so that the situation that the compressed air escapes to the outboard to expose a target is avoided, the situation that the compressed air is released into a cabin to increase the air pressure of the cabin and gas with peculiar smell is avoided, and the device is flexible to use and can be used at any depth within the limit depth.
本发明提供了一种压力平衡式水下厕所排污装置,属于排污装置技术领域,旨在解决现有的潜艇水下厕所使用效果不好的问题;包括储容桶、活塞和推杆;所述储容桶包括桶体和两个端盖;两个所述端盖分别固定在所述桶体的两端;所述活塞活动置于所述桶体内;其中一个所述端盖上设有容纳所述推杆的通孔,所述推杆的一端穿过所述通孔并延伸至所述桶体内,所述推杆与所述活塞固定连接;本发明中的设计,不使用压缩空气作为排污方式,避免了向舷外逸出压缩空气暴露目标,避免了向舱内释放压缩空气增加舱室气压和有异味的气体,并且使用灵活,可以在极限深度内的任何深度使用。
