[0002] A depth sounder is a device used to measure water depth. It is widely used in the field of marine surveying and mapping. Depth sounders and their applications play an important role in marine surveying and mapping, providing key data support for marine geological research, marine resource exploration, seabed topography mapping, and marine engineering construction. Through the use of these devices, we can better understand the marine environment, ensure the sustainable use of marine resources and the safe implementation of marine engineering projects.

[0003] A Chinese patent document with authorization announcement number CN218383292U proposes an ocean depth sounder that is easy to retract, belonging to the field of marine humanities technology. The ocean depth sounder that is easy to retract includes a fixed frame, the bottom end of the fixed frame is rotatably connected to a gear, the outer end of the fixed frame is fixedly connected to a fixed frame, the interior of the fixed frame is slidably connected to a first tooth plate, and the bottom end of the first tooth plate is fixedly connected to a mounting cover.

[0004] In the above application, although the outer end of the transducer can be protected, the protection is not adequate, and some protruding reefs can still penetrate into the interior of the mounting cover through the opening at the lower end of the mounting cover, causing damage to the transducer. In addition, the existing transducer lacks a positioning structure. Due to the flow of water on the seabed, this may cause the transducer to drift around with the waves and cannot stabilize, which in turn leads to inaccurate detection values. Utility Model Content

[0008] Preferably, a waterproof cover is provided at the side wall of the hollow rod to prevent seawater from entering the hollow rod through the chute; and a thick rope is provided through the waterproof cover.

[0009] Preferably, a clamping sleeve is provided at the lower end of one protective cover, and a clamping rod which is clamped with the clamping sleeve is provided at the lower end of the other protective cover.

The positioning component 8 is arranged on the transducer 6 to provide support for the transducer 6.

[0025] The setting of the protection component 7 can provide protection for the transducer 6, prevent the transducer 6 from being damaged by impact during the falling process of the transducer 6, and also prevent the transducer 6 from being scratched by sharp objects such as rocks, thereby extending the service life of the transducer 6. The setting of the positioning component 8 can be inserted on the seabed to position the transducer 6, preventing the transducer 6 from wandering around with the flow of seawater and failing to be stably placed on the seabed, resulting in inaccurate detection values.

[0026] Embodiment 2

[0027] like Figure 1-5 As shown, the depth sounder retracting and releasing device proposed by the utility model, compared with the first embodiment, this embodiment also includes: the protection component 7 includes a hollow rod 71 connected to the upper end of the transducer 6; a sleeve 75 is slidably sleeved on the outer wall of the hollow rod 71, and a slide groove 72 is opened on both sides, and a cylinder 73 is arranged inside; the telescopic end of the cylinder 73 is connected to a connecting column 74 connected to the sleeve 75; the connecting column 74 is slidably arranged at the slide groove 72; two thick ropes 76 are also connected to the sleeve 75; the other ends of the two thick ropes 76 are connected to protective covers 77 one by one; the two protective covers 77 are both rotatably connected to the hollow rod 71, and the two protective covers 77 can rotate around the hollow rod 71 to a closed state, and cover the transducer 6 therein. Providing protection for the transducer 6 can prevent the transducer 6 from being damaged by impact during the falling process of the transducer 6, and can also prevent the transducer 6 from being scratched by sharp objects such as rocks, thereby extending the service life of the transducer 6.

[0028] Further, a waterproof cover 710 is provided on the side wall of the hollow rod 71 to prevent seawater from entering the hollow rod 71 from the chute 72; a thick rope 76 is provided through the waterproof cover 710 to prevent seawater from corroding the protective component 7 and prevent the cylinder 73 from being damaged by water.

[0029] Further, a clamping sleeve 78 is provided at the lower end of one protective cover 77, and a clamping rod 79 is provided at the lower end of the other protective cover 77 to be clamped with the clamping sleeve 78. The protective cover 77 is limited to prevent the protective cover 77 from being opened outwards by the impact of seawater during the falling process, thereby making the protection of the transducer 6 ineffective.

[0030] Further explanation: there are multiple groups of positioning components 8 around the circumference array of transducer 6, so that the positioning components 8 can support transducer 6 more stably.

[0031] Further explanation, the positioning assembly 8 includes a rotating column 81 rotatably connected to the transducer 6; the rotating column 81 is connected to a leg 82 for supporting the transducer 6, and torsion springs 83 are also connected to both sides; the other ends of the two torsion springs 83 are respectively connected to connecting plates 84. The legs 82 can be inserted on the seabed to position the transducer 6, so as to prevent the transducer 6 from wandering around with the flow of seawater, resulting in inaccurate detection values.

[0032] Further, a connecting sleeve 85 is provided on the outer sleeve of the torsion spring 83; one end of the connecting sleeve 85 is connected to the connecting plate 84, and the other end is rotatably connected to the rotating column 81, so as to prevent seawater from entering and corroding the torsion spring 83.

[0034] The working principle of the utility model is as follows: when working, the transducer 6 is first thrown into the sea, and the motor 4 is started to drive the cable 5 to be lowered, so that the transducer 6 sinks to the seabed. After the transducer 6 reaches the seabed, the cylinder 73 is started, and the telescopic end of the cylinder 73 extends to drive the connecting column 74 and the sleeve 75 to slide up along the slide 72, thereby pulling the thick rope 76 upward, and then the protective cover 77 is opened to both sides around the hollow rod 71 to expose the transducer 6. It can provide protection for the transducer 6, prevent the transducer 6 from being damaged by impact during the falling process of the transducer 6, and also prevent the transducer 6 from being scratched by sharp objects such as rocks, thereby extending the service life of the transducer 6. After the lower end of the transducer 6 is attached to the seabed, the legs 82 will open around the torsion spring 83 and be inserted on the seabed ground, providing support and positioning for the transducer 6, preventing the transducer 6 from wandering around with the flow of seawater and failing to be stably placed on the seabed ground, thereby causing inaccurate detection values.
