Referring to fig. 1, a buoyancy adjusting mechanism of an underwater glider includes a first cabin 1 and a second cabin 2 disposed below the first cabin 1, the first cabin 1 and the second cabin 2 are connected through a first valve 3, and the second cabin 2 is connected to an airbag 5 through a gas pipe 4;
the first cabin body 1 is used for containing a first substance, the first cabin body 1 is used for containing a second substance, the first substance 1 can react with the second substance to generate gas, and the gas enters the air bag 5 through the gas conveying pipe 4.
In order to facilitate the discharge of the gas in the air bag, the air bag 5 is connected with an air outlet pipe 6, and the air outlet pipe 6 is connected with a second valve 7.
Preferably, the first valve 3 and/or the second valve 7 are one-way valves.
For automatic control, the first valve 3 and/or the second valve 7 are one-way solenoid valves.
Preferably, the first substance is hydrochloric acid or sulfuric acid and the second substance is calcium carbonate, magnesium carbonate or sodium carbonate.
Preferably, the first substance is hydrochloric acid and the second substance is calcium carbonate.
The invention reduces energy consumption, has large amount of gas of carbon dioxide released by the reaction of calcium carbonate and hydrochloric acid, low price, safety, no pollution caused by the released gas and environmental protection.
Preferably, the gas transmission pipe 4 is a copper pipe, the gas bag 5 is a rubber gas bag, one end cover of the second cabin body 2 is connected with one end of the gas transmission pipe 4, and the other end of the gas transmission pipe 4 is connected with the gas bag 5;
in order to achieve better sealing, a first sealing joint 8 is arranged below the first cabin body 1, a second sealing joint 9 is arranged above the second cabin body 2, and a first valve 3 is connected between the first sealing joint 8 and the second sealing joint 9.
Referring to fig. 2 and 3, the present invention further provides an underwater glider, which comprises the underwater glider 10 and a casing 11, wherein the underwater glider 10 and a pressure-resistant cabin 12 are arranged in the casing 11.
