Description

Technical Field

[0001] The utility model relates to the technical field related to underwater acoustic engineering, and more specifically to a portable underwater acoustic beacon detection device. Background Art

[0002] With the increasing frequency of human marine activities, these underwater equipment often sink underwater due to accidents during marine operations such as marine environmental monitoring and sea trials of important equipment. If there is no long-distance underwater positioning means on the target, it is difficult to determine the true position of the target and salvage it in the vast ocean, which brings great difficulties to the search, positioning and recovery of these equipment, and is also very likely to cause large economic losses. As an important underwater positioning means, hydroacoustic beacons are often installed on marine equipment to solve the search, positioning and recovery of underwater targets.

[0003] The shortcomings of the existing technology are: the underwater acoustic beacon is in an inactive state in the air. After the underwater acoustic beacon enters the water, the trigger electrode on the surface of the shell is connected to the beacon shell through the seawater, activating the beacon to work and radiate sound wave signals into the water. It is used for underwater positioning of marine equipment and equipment after entering the water. Detection equipment is required to locate the underwater acoustic beacon. Existing detection devices are generally fixed structures with large size. They cannot be retracted when not in use, making them inconvenient to carry. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a portable underwater acoustic beacon detection device to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a portable underwater acoustic beacon detection device, comprising a detection device, one side of the detection device is fixedly connected to a retractable shell, one side of the retractable shell is fixedly connected to a propulsion device, the retractable shell includes a closing block, a spring and a shell are fixedly connected between the closing blocks, the inner side of the closing block is fixedly connected to a winding device, and a connecting rope is fixedly connected between the winding devices.

[0006] Preferably, the detection device includes a detection body, and a signal transmission rod is fixedly connected to the interior of the detection body.

[0007] Preferably, the detection body is made of a transparent material, and an acoustic wave detector is provided inside the detection body.

[0008] Preferably, the winding device includes a fixed block, one side of the fixed block is fixedly connected to the winding motor, one side of the winding motor is fixedly connected to a rotating column, and the outer side of the rotating column is fixedly connected to a winding wheel.

[0010] Preferably, the propulsion device includes a fixed shell, the interior of the fixed shell is fixedly connected to a propulsion motor, one side of the propulsion motor is fixedly connected to a rotating shaft, and the outer side of the rotating shaft is fixedly connected to fan blades.

[0011] The technical effects and advantages of this utility model are:

[0012] The utility model is convenient for storing the detection device by providing a retractable shell. By starting the reeling motor, the rotating column can drive the reeling wheel to rotate, thereby making it possible to retract the connecting rope so that it can be rolled onto the reeling wheel. At the same time, the shell is retracted, thereby making the volume of the device smaller, which is convenient for carrying. When in use, it can be directly put into water to dive. When it needs to rise, the reeling wheel is rotated in the opposite direction, thereby making it possible to release the connecting rope. Under the action of the spring, the shell can be expanded, so that its internal space becomes larger, thereby making its buoyancy greater, so that the device can be easily risen.
