Description

Technical Field

[0001] The utility model relates to the technical field of underwater detection equipment, and specifically relates to a side-scan sonar crash wing device. Background Technique

[0002] A side-scan sonar is an instrument that uses the principle of echo sounding to detect submarine landforms and underwater objects. It is used for underwater target detection in coastal waters, far seas, and oceans. A typical side-scan sonar device mainly consists of a data display and recording unit, a data transmission and towing cable, and an underwater acoustic wave transmitting and receiving transducer. Its detection principle is to use the differences in the backscattering characteristics of submarine surface substances to judge the sedimentary properties or morphological characteristics of the target object. When the side-scan sonar operates, it sends wide-angle (vertical direction) acoustic wave beams to both sides, which can cover a large area of the seabed. Usually, the detection width of each strip on one side can reach dozens of meters to hundreds of meters, and then the backscattering data returned from the seabed is received to image the seabed. According to different detection purposes, different frequencies of transmitting beams can be selected. According to the working mode, it can be divided into two categories: shipborne fixed installation and watertight cable towed type. The utility model mainly relates to the towed side-scan sonar. When working, the side-scan sonar tow body is towed behind the ship by a watertight cable and sails along a pre-determined survey line.

[0003] At present, the diving depth of the side-scan sonar tow body during operation is mainly adjusted by changing the ship speed, finely adjusting the length of the tow cable, or increasing or decreasing the counterweight. When a greater diving depth is required, the ship speed needs to be reduced, the length of the underwater cable needs to be increased, or counterweight blocks need to be added. However, these methods all have certain limitations. Reducing the ship speed to increase the diving depth will result in a decrease in operation efficiency, while increasing the length of the tow cable and the counterweight will result in a loss of maneuverability, and there will also be an additional risk of losing the tow body caused by colliding with underwater foreign objects. Other types of marine tow bodies, such as magnetometers, use hydrofoils to increase the diving depth of the tow body. However, there is no application of a crash device on the side-scan sonar tow body. Therefore, developing a crash wing device that can be applied to the fine adjustment of the diving depth of the side-scan sonar tow body can significantly improve the operation efficiency of the side-scan sonar tow body. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a side-scan sonar crash wing device, which can conveniently and flexibly adjust the diving depth of the side-scan sonar tow body to meet the operation requirements of the side-scan sonar at different water depths and improve the operation efficiency of the side-scan sonar tow body.

[0005] To achieve the above object, the present utility model provides the following technical solution: A side-scan sonar descent wing device is installed on the side-scan sonar handle at the upper end of the side-scan sonar tow body. The descent wing device includes a main wing, a tow body adapter plate, and several fasteners; the main wing is arranged at the upper end of the tow body adapter plate; the lower part of the tow body adapter plate is movably connected to the side-scan sonar handle through the fasteners. Among them, an angular fine-tuning hole with an arc-shaped structure is opened at the lower part of the tow body adapter plate, and the fastener passes through the angular fine-tuning hole and the side-scan sonar handle.

[0006] Preferably, the angular fine-tuning hole is in the structure of a minor arc.

[0007] Preferably, a positioning hole is further opened at the lower part of the tow body adapter plate; the angular fine-tuning hole is opened around the axis of the positioning hole; the fastener passes through the positioning hole and the side-scan sonar handle.

[0008] Preferably, several mounting holes are opened on the main wing body; the tow body adapter plate is fixedly connected to the main wing through fasteners and mounting holes at different positions to change the relative position between the main wing and the side-scan sonar tow body.

[0009] Preferably, a U-shaped groove corresponding to the positions of the side-scan sonar handle and the mounting holes is opened in the middle of the main wing.

[0010] Preferably, several mounting holes are arranged and distributed along the length direction of the U-shaped groove.

[0011] Preferably, the included angle between the upper end surface of the tow body adapter plate and the horizontal plane is 10°.

[0013] Preferably, a wing tip sail is provided at each end of the main wing body, and the wing tip sails are arranged downward.

Specific embodiments

[0023] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice the present utility model. Although the present utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative and do not limit the scope of the present utility model.

[0024] Specific embodiment 1: Please refer to Figures 1-6 A sidescan sonar crash landing wing device, which is installed on the sidescan sonar handle 61 at the upper end of the sidescan sonar tow body 6. The length direction of the sidescan sonar handle 61 is parallel to the axis of the sidescan sonar tow body 6. The crash landing wing device includes: a main wing 1, a tow body adapter plate 3 and fasteners. The main wing 1 is movably arranged on the sidescan sonar handle 61 through the tow body adapter plate 3 and fasteners. Specifically, the main wing 1 can rotate up and down relative to the sidescan sonar tow body 6 with the tow body adapter plate 3 as a fulcrum to adjust the angle between the main plane of the main wing 1 and the axis of the sidescan sonar tow body 6. In this way, in the water flow, the lift force applied by the main wing 1 to the sidescan sonar tow body 6 can be conveniently adjusted, so that the water entry depth of the sidescan sonar tow body 6 can be conveniently and flexibly adjusted to meet the operation requirements of the sidescan sonar at different water depths and improve the operation efficiency of the sidescan sonar tow body.

[0025] Specifically, the fasteners include a position fine-tuning screw 2, a positioning screw 4 and an angle fine-tuning screw 5. The tow body adapter plate 3 is installed on the sidescan sonar handle 61 through the positioning screw 4 and the angle fine-tuning screw 5, and the main wing 1 is arranged on the tow body adapter plate 3 through the position fine-tuning screw 2.

[0026] The main wing 1 has an airfoil with a planar angle of attack. At both ends of the main body of the main wing 1, a wing tip sail 11 is provided, and the wing tip sails 11 are arranged downward; at the front part of the middle of the main body of the main wing 1, a U-shaped groove 13 is opened, and a number of mounting holes 12 distributed in an array are opened on both sides in the length direction of the U-shaped groove 13; it should be noted that the U-shaped groove 13 corresponds to the position of the side-scan sonar handle 61. When the main wing 1 is turned up and down relative to the side-scan sonar tow body 6, the U-shaped groove 13 can prevent the side-scan sonar handle 61 from blocking the main wing 1, which is convenient for adjusting the angle between the main plane of the main wing 1 and the axis of the side-scan sonar tow body 6.

[0027] In one embodiment, the main wing 1 is made of stainless steel, and 316L stainless steel can be selected during implementation; of course, the material of the main wing 1 is not limited to the above-mentioned stainless steel, and can be adjusted according to actual situations. For example, in order to reduce the corrosion of the main wing by seawater, the main wing 1 can be made of a material with high corrosion resistance, such as plastic material, alloy material, etc.

[0028] The tow body adapter plate 3 is a T-shaped connection structure composed of a support plate 31 and two connecting plates 32; the two connecting plates 32 are fixedly arranged at the lower end of the support plate 31; a main wing mounting screw hole 311 is opened on the support plate 31. After assembly, the position fine-tuning screw 2 passes through the main wing mounting screw hole 311 and is arranged with the mounting hole 12; in this embodiment, the number of the position fine-tuning screw 2 and the main wing mounting screw hole 311 is preferably four, and six are arranged in each row of the two rows of mounting holes 12. By selecting mounting holes 12 at different positions, the mounting position of the main wing 1 relative to the side-scan sonar tow body 6 can be finely adjusted. It can be understood that the fine adjustment of the mounting position of the main wing 1 can adjust the center of gravity of the side-scan sonar tow body 6; in this embodiment, the angle between the main plane of the support plate 31 and the horizontal plane is 10°.

[0029] In one embodiment, in order to adjust the center of gravity of the crash landing wing device mounted on the side-scan sonar tow body 6, the number of the mounting holes 12 is not limited to the above two rows and six in each row; the opening positions of the mounting holes 12 are not limited to the distribution along the length direction of the U-shaped groove 13.

[0030] A positioning hole 321 and an angle fine-tuning hole 322 are opened on the connecting plate 32. After assembly, the side-scan sonar handle 61 is located between the two connecting plates 32. The positioning screw 4 passes through the positioning hole 321, and the angle fine-tuning screw 5 passes through the angle fine-tuning hole 322; in this embodiment, the angle fine-tuning hole 322 is an inferior arc structure, the angle fine-tuning hole 322 is opened around the axis of the positioning hole 321, and the angle fine-tuning hole 322 is located behind the positioning hole 321.

[0031] When it is necessary to adjust the angle between the main plane of the main wing 1 and the axis of the side-scan sonar towed body 6, the towed body adapter plate 3 can be rotated with the positioning hole 321 as the center and the angle fine-tuning hole 322 as the constraint angle to finely adjust the angle between the main plane of the main wing 1 and the axis of the side-scan sonar towed body 6. The larger the angle of attack of the main wing 1, the greater the downward pressure of the main wing 1 on the side-scan sonar towed body 6, and at this time, the deeper the side-scan sonar towed body 6 enters the water.

[0032] Through this technical solution, by arranging the emergency landing wing device on the upper side of the side-scan sonar towed body, and the emergency landing wing device is movably connected to the side-scan sonar towed body. By finely adjusting the installation position of the main wing of the emergency landing wing device and the angle between the wing surface and the horizontal plane, the water entry depth of the side-scan sonar towed body can be conveniently and flexibly increased, so as to meet the operation requirements of the side-scan sonar for different underwater magnetic targets and improve the operation efficiency of the side-scan sonar towed body.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
