Description

Technical Field

[0001] The utility model relates to the technical field of underwater detection equipment, in particular to an automatic retracting and releasing device applied to underwater detection equipment. Background Art

[0002] Underwater detection technologies mainly include acoustic detection, electromagnetic detection, lidar detection, etc. Among them, acoustic detection is the most commonly used method. It mainly emits sound waves and then receives the reflected sound waves. According to the propagation time and intensity of the sound waves, the distance, speed, direction and other information of the underwater target are judged. At present, the retraction and deployment of ship underwater detection equipment are mostly manual or bulky mechanical equipment, which is extremely inconvenient to use and often accompanied by safety hazards. In addition, the general retraction and deployment device cannot adjust the position of the underwater detection equipment, which makes the detection process more cumbersome and cannot conveniently maintain and repair the retraction and deployment rope.

[0003] According to the description in an automatic retractable device for underwater detection equipment published on the patent website (authorization announcement number: CN220186387U), the automatic retractable device for underwater detection equipment includes "a column, a rotating component, a rectangular box, a telescopic component", etc. to retract and extend the detection equipment.

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] The automatic retracting and extending device of the underwater detection equipment utilizes a column, a rotating component, a rectangular box, a telescopic component, etc. to retract and extend the detection equipment. However, when this device is in use, the position of the detection equipment is adjusted by bevel gear tires. There is no self-locking function between the bevel gears, which causes movement due to other factors after adjustment, affecting the stability of the detection equipment. In addition, when the steel rope needs to be inspected and maintained, the staff must climb through external equipment to perform maintenance and repair, which is inefficient. Therefore, the device needs to be improved. Utility Model Content
