Description

Technical Field

[0001] This utility model relates to the technical field of sonar measurement, and in particular to a marine mapping sonar deployment and retrieval device. Background Technology

[0002] Sonar is an electronic device that uses sound waves in water to detect, locate, and communicate with underwater targets. It is the most widely used and important device in underwater acoustics. When inspectors are testing the depth of a sea area, they will usually send sonar devices to the target depth for sonar testing.

[0003] During the descent of a sonar device, it is not easy to know the length of the descent, making it difficult to place the sonar device at the corresponding depth. During the retrieval process, the traction rope is prone to carrying moisture, which can get tangled on the reel and cause corrosion over time. Utility Model Content

The embodiments described are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0021] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] like Figures 1 to 3 As shown, a marine mapping sonar deployment and retrieval device includes a fixed base 1, on which a sonar traction wire winding mechanism 2, a guide length measuring mechanism 3, and a compression dehumidification mechanism 4 are installed.

[0025] The fixed base 1 is used to fix the entire device.

[0026] The fixed base 1 has several fixing holes 5, which can be used to connect to the bottom plate of the hull.

[0027] The fixed base 1 has a fixed side plate 6 on one side, and the fixed side plate 6 has a connection hole 7. The fixed side plate 6 can also be used to fix the entire device to the bracket or other parts on the hull.

[0028] The sonar traction wire winding mechanism 2 includes two vertical plates 21 mounted on a fixed base 1. A lead screw 22 is installed between the two vertical plates 21. The lead screw 22 is connected to a drive motor 23. A wire nut seat 24 is threaded onto the lead screw 22. A winding shaft 26 is rotatably mounted on the wire nut seat 24 via two mounting plates 25. The winding shaft 26 is connected to a winding motor 27. A limiting rod is passed through the wire nut seat 24, and the two ends of the limiting rod are fixed to the vertical plates 21.

[0029] The sonar traction wire 8 can be wound onto the winding shaft 26 more evenly by driving the lead screw 22 to rotate via the drive motor 23, which in turn drives the lead screw 24 to move.

[0030] The guiding length measuring mechanism 3 includes a support plate 31 mounted on a fixed base 1. A rear guide frame 32 is mounted on the support plate 31. A support plate 33 is mounted in front of the rear guide frame 32. A front guide frame 34 is mounted in front of the support plate 33. Two rear guide rollers 35 are mounted inside the rear guide frame 32 via a rotating shaft. Two extrusion length measuring rollers 36 are mounted on the support plate 33 via a rotating shaft. A counter 37 is connected to the rotating shaft of one of the extrusion length measuring rollers 36. Two front guide rollers 38 are mounted inside the front guide frame 34 via a rotating shaft. Anti-slip ridges 39 are evenly distributed on the outer wall of the extrusion length measuring roller 36.

[0031] The sonar traction line 8 passes between the front guide roller 38 and the rear guide roller 35, which serves as a guide and, due to its rolling structure, reduces wear on the sonar traction line 8. The sonar traction line 8 passes between the two extrusion measuring rollers 36, causing the extrusion measuring rollers 36 to rotate. The counter 37 can measure the number of rotations of the extrusion measuring rollers 36 and calculate the length of the extrusion measuring rollers 36 as they are lowered. The sonar traction line 8 can control the position of the sonar measuring device 9.

[0032] The extrusion dehumidification mechanism 4 includes a guide plate 41 installed on the front side of the fixed base 1. The guide plate 41 has a guide hole 42. Extrusion cylinders 43 are installed on both sides of the bottom of the guide plate 41. A dehumidification sponge block 44 is installed at the end of the piston rod of the extrusion cylinder 43.

[0033] During the retrieval of the sonar traction cable 8, two dehumidifying sponge blocks 44 can be used to squeeze and remove the seawater carried on the sonar traction cable 8, preventing moisture from corroding other components. The dehumidifying sponge blocks 44 can be squeezed to remove water periodically.

[0034] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
