As preferably, being provided with Hard link pipe between described open and close valve and flexible mouth, the rear sleeve of flexible mouth is located at the outside of Hard link tube end.
As preferably, between described flexible mouth rear end and Hard link pipe lateral wall, it is additionally provided with the bellow seal set of closing.Nitrogen passage in hollow stem forms sealed environment, it is ensured that having certain impulsive force after nitrogen ejection can spread rapidly.
As preferably, it is 10cm that described flexible mouth stretches out the greatest length of hollow stem front end.
As preferably, described hollow stem front end is the most concordant with the head rope catching net.When after jet completes, net seizure is caught in employing, the front end of hollow stem will not impact catching net use.
As preferably, described open and close valve is provided with effusion meter.Can suitably control the nitrogen use level of unit are, it is ensured that cave controls as low-oxygen environment rather than anoxybiotic environment, it is to avoid hypoxia death in the aquatic organism short time of living in caves.
As preferably, described flexible pipe is bimetallic tube, and internal layer is trachea, and outer layer is protection pipe.
As preferably, the one or both ends of described carrier upwards arc tilts.
The present invention utilizes the aquatic organism that lives in caves to need the characteristic of ventilation, low-oxygen environment is caused in nitrogen is squeezed into the cave in beach, the aquatic organism that will live in caves is driven to earth's surface ventilation and catches, this device will not destroy cave environment in capture-process, and low-oxygen environment can be improved in the short time during air natural flow and tide rise and fall, little to the breeding environmental effect of the aquatic organism that lives in caves, it is achieved sustainable development.
