When the robot goes wrong, the robot loses control and begins to sink, because ballast water exists in the sealed cabin 23 in the submergence process, the water in the sealed cabin 23 still needs to be discharged in order to enable the robot to quickly float upwards, when the robot begins to sink, the pressure at the trigger device 21 gradually rises, the preset pressure is arranged in the trigger device 21, the trigger device 21 can be triggered only when the external pressure reaches the preset pressure, the trigger device 21 is of a mechanical structure, and the pressure value of the preset pressure needs to be smaller than the maximum design compression resistance value of the robot, otherwise, the pressure of external seawater can be used for compressing the robot in the submergence process of the robot, and the robot can not be damaged by the seawater pressure before floating upwards only if the preset pressure is smaller than the maximum design compression resistance value of the robot. When the pressure of seawater reaches the preset pressure, the triggering device 21 is triggered, the triggering device 21 activates the gas reactor 22, the gas reactor 22 generates gas, the gas enters the sealed cabin 23 through the first connecting pipe 24, ballast water in the sealed cabin 23 is extruded by the gas, the overall weight in the sealed cabin 23 is reduced, then the transmission device 25 pumps the gas into the air bag 26, the air bag 26 ejects the robot to float out of the water, the instantaneous pressure of the gas reactor 22 generates gas is maximum, ballast water is stored in the sealed cabin 23, if the water in the sealed cabin 23 is required to be discharged, the sufficient pressure is required to enter the sealed cabin 23, the gas generated by the gas reactor 22 needs to enter the sealed cabin 23 through the first connecting pipe 24, after the water in the sealed cabin 23 is discharged, the transmission device 25 can discharge the gas generated in the gas reactor 22 into the air bag 26, the sealed cabin 23 can provide buoyancy for the robot, under the double functions of the air bag 26 and the sealed cabin 23, the robot can quickly float out of the water after the problem, and meanwhile, the safety device 2 cannot normally run due to the use of the safety device.
Referring to fig. 2, 3 and 10: the triggering device 21 includes a triggering block 211, a button 212, and a safety device 213; the trigger block 211 is slidably arranged on the side wall of the shell 1 along the length direction of the shell 1, and the trigger block 211 penetrates through the side wall of the shell 1; the button 212 is arranged in the shell 1, the button 212 is positioned at one side of the end part of the triggering block 211, the button 212 is connected with the gas reactor 22 and can trigger the gas reactor 22, and the triggering block 211 can trigger the button 212; a safety device 213 is provided on the trigger block 211, and the safety device 213 restricts the trigger block 211 when the external pressure does not reach the preset pressure.
In the process of the robot submerging, the water flow in the ocean can form impact on the side wall of the robot shell 1, if the safety device 213 is not arranged, the trigger block 211 slides under the impact of the water flow, the condition that the trigger block 211 accidentally triggers the button 212 is easily caused, after the safety device 213 is arranged, the external pressure is gradually greater than the preset pressure along with the sinking of the robot only when the robot breaks down, the safety device 213 is unlocked at the moment, the trigger block 211 can slide freely, and the trigger block 211 can press the button 212 to trigger under the pressure action of external seawater.
