Problems solved by technology

Traditional ROV has many problems such as relatively low operating ability, poor mobility, limited number of video transmission channels and transmission distance, poor human-computer interaction ability and scalability, etc., which cannot meet the requirements of ROV in today's marine, military and other related industries or departments. needs
[0003] At present, when the existing submarine sonar robot is in use, because the robot needs to be placed on the seabed, and in order for the robot to float up quickly in case of abnormal conditions, it is necessary to install a floating device outside the robot, but the existing floating device adopts such as The form of automobile anti-collision airbags, such as the existing patented technology CN111252223A and CN105083506A, all utilize the automatic bounce of the airbag in an emergency to realize temporary floating, but the above-mentioned devices all have the following existing technical defects: 1. , expands rapidly and floats upwards. During the floating process of the robot, due to the sudden expansion of the airbag, the buoyancy of the seawater on the airbag is also suddenly applied to the airbag. At this time, the robot is in a state of uniform speed or static, so the state of motion changes suddenly. During the process, the connection between the floating device and the robot will be broken or deformed from time to time, resulting in damage to the device and affecting the rational use of resources; The suction cup type is not easy to disassemble, and it is not convenient to replace the airbag. The suction cup type is prone to misoperation and is easy to be separated from the equipment during the rapid expansion of the airbag; 3. In addition, some existing underwater equipment needs to be kept at Specific attitudes during the floating process, such as tilting attitudes, and the existing tilting attitudes generally need to be adjusted comprehensively by using propellers set in multiple directions on the shell of underwater equipment, and the adjustment efficiency is low

Abstract

The invention relates to the technical field of underwater robots, in particular to an emergency suspension device. An emergency levitation device for a submarine sonar robot, comprising: a connecting base, the top of which is provided with a support cylinder, a connecting ring and a top cover, a bellows is connected between the connecting ring and the top cover and an air bag cover is arranged; a slow-lift mechanism, which includes The No. 1 self-locking motor and the mounting base, and the No. 1 screw rod is connected with the threaded cylinder at the center of the mounting base; and the rapid lifting mechanism, which includes the No. 2 self-locking motor and the No. 2 screw rod, and the No. 2 screw rod is connected to the support tube Threaded barrel connection on top. In the present invention, by setting the screw drive between the top cover and the connecting ring, the volume formed by the bellows between the top cover and the connecting ring can be freely adjusted according to the needs, which is convenient for the robot to move up slowly; The gas generator is equipped with a solenoid valve on the partition, which can freely adjust the expansion degree of the airbag cover according to the needs, thereby controlling the floating speed of the robot.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to an emergency suspension device. Background technique [0002] Underwater robot, or remotely controlled unmanned submersible, is a kind of diving equipment that uses its own equipment to carry out human-controlled operations underwater. ROV is currently the most widely used submersible in the world. It is used in marine engineering and military, etc. domain plays an important role. Traditional ROV has many problems such as relatively low operating ability, poor mobility, limited number of video transmission channels and transmission distance, poor human-computer interaction ability and scalability, etc., which cannot meet the requirements of ROV in today's marine, military and other related industries or departments. demand. [0003] At present, when the existing submarine sonar robot is in use, because the robot needs to be placed on the seabed, and in order for the r...
