Description

A natural air circulation device for sightseeing submarines and a sightseeing submarine Technical field '

The present invention relates to a natural air circulation device for sightseeing submarines. The invention also relates to a sightseeing submarine using a natural air circulation device.

Background technique

. At present, the manufacturing technology of sightseeing submarines at home and abroad basically applies the basic concepts of military submarines. The difference is that there are no weapons and related technical facilities for military purposes and demanding technologies and equipment in terms of maneuverability, concealment and confrontation. °

As a sightseeing submarine, its biggest disadvantages are: it is expensive to build, difficult to operate, and complex to maintain. It is very difficult to provide first aid in the event of an underwater failure. '

As the current civilian sightseeing submarines, the diving depth is generally around 20-50 meters, and the deepest one does not exceed 100 meters. It is less difficult in the emergency area and provides the possibility of diversified first aid measures, but it still has strong limitations. For example, when a general sightseeing submarine breaks down underwater, although it has a life support system that lasts for dozens of hours, if first aid measures cannot be effective within dozens of hours, life is very unsafe. Generally, when a submarine dives 5-10 meters underwater, it must start the oxygen generator or spare oxygen bottles and tanks. Its disadvantages are: the gas chemical threat ratio is very high, otherwise it will cause discomfort or poisoning to the occupants, and there are certain limits on the ambient temperature and use time. Especially once the submarine's underwater power fails, the troubleshooting time exceeds the oxygen supply, which will endanger the lives of the crew members. Although my country's civilian sightseeing submarine emergency technology has undergone some improvements and innovations, providing new technologies for safety terminals, certain objective power conditions are still required to be effective, and there are still many uncertain factors. . - To sum up, the current submarines still have the following problems: 1. The cost is too high and the market cannot accept it; 2. The technology is complex, management is difficult, and maintenance is difficult; 3. There are still many problems in terminal security technology.
