A sewage collection device and collection method for a saturation diving ship

Abstract

The invention relates to the technical field of diving equipment, and discloses a sewage collection device for a saturated diving ship, which is provided with a first sensor and a hyperbaric chamber of a toilet, and a first valve and a first normally closed reset valve are provided on the sewage discharge pipe of the toilet. A second valve and a third valve are arranged between the sewage pipe and the sewage tank provided with the second sensor, the vacuum pump is connected with the sewage tank, the sewage tank is connected with the sewage collection box through the second connecting pipe, and a saturated diving In the collection method of the ship's sewage collection device, the main controller controls the start and stop of the vacuum pump according to the air pressure in the hyperbaric cabin and the air pressure in the sewage tank. The invention can make the hyperbaric cabin in a low-pressure state, and can still efficiently collect sewage. Discharge to the outside of the cabin, high safety, and does not destroy the airtightness of the hyperbaric cabin.

Description

technical field [0001] The invention relates to the technical field of diving equipment, in particular to a sewage collection device and a collection method for a saturation diving ship. Background technique [0002] The hyperbaric chamber (decompression chamber (DDC), transition chamber (TUP)) in a saturation diving boat is a hyperbaric chamber that theoretically divers can live in for a long time. A resting place during the decompression waiting period after the completion of the diving operation, and because of the special nature of the diving operation, the cost of decompression and decompression is relatively expensive, so sometimes even after the diver completes the diving operation, he will not decompress and exit the cabin immediately but continue to wait in the hyperbaric chamber , and the hyperbaric chamber is a confined space with high pressure and airtightness, and it is impossible to install a domestic sewage collection device. The domestic water needs to be dis...

[0002] The hyperbaric chamber (decompression chamber (DDC), transition chamber (TUP)) in a saturation diving boat is a hyperbaric chamber that theoretically divers can live in for a long time. A resting place during the decompression waiting period after the completion of the diving operation, and because of the special nature of the diving operation, the cost of decompression and decompression is relatively expensive, so sometimes even after the diver completes the diving operation, he will not decompress and exit the cabin immediately but continue to wait in the hyperbaric chamber , and the hyperbaric chamber is a confined space with high pressure and airtightness, and it is impossible to install a domestic sewage collection device. The domestic water needs to be discharged to the normal pressure environment outside the cabin for collection. The resulting pressure difference discharges the domestic sewage out of the cabin, but when the hyperbaric chamber is at low pressure (such as the initial stage of pressurization of the hyperbaric chamber and the end of decompression of the hyperbaric chamber), it is difficult to discharge the domestic sewage from the hyperbaric chamber to the outside of the cabin
