The invention relates to the technical field of diving equipment, and discloses a sewage collecting device of a saturated diving boat. The sewage collecting device comprises a hyperbaric cabin provided with a first sensor and a closestool, wherein a first valve and a first normally-closed reset valve are arranged on a blow-off pipe of the closestool, a second valve and a third valve are arranged between the blow-off pipe and a sewage tank provided with a second sensor, a vacuum pump is connected with the sewage tank, and the sewage tank is connected with a sewage collecting tank through a second connecting pipe. Meanwhile, the invention further discloses a collecting method of the sewage collecting device of the saturated diving boat. The vacuum pump is controlled to be turned on or turnedoff by a main controller according to the air pressure in the hyperbaric cabin and the air pressure in the sewage tank. By adopting the sewage collecting device, the hyperbaric cabin can be in a low-pressure state, sewage can still be efficiently discharged out of the cabin, the safety is high, and the leakproofness of the hyperbaric cabin is not damaged.

    本发明涉及潜水设备技术领域,公开了一种饱和潜水船的污水收集装置,设有第一传感器和马桶的高压舱,马桶的排污管上设有第一阀门和第一常闭式复位阀,排污管与设有第二传感器的污水罐之间设有第二阀门和第三阀门,真空泵与污水罐连接,污水罐通过第二连接管与污水收集箱连接,同时还公开了一种饱和潜水船的污水收集装置的收集方法,主控器根据高压舱内的气压与污水罐内的气压的情况来控制真空泵的启停,采用本发明能使高压舱处于低压状态下,仍能够将污水高效排放至舱外,安全性高,且不破坏高压舱的密闭性。
