Description

Technical Field

[0001] The utility model relates to the technical field of marine surveying and mapping equipment, in particular to a shipborne side-scan sonar and a mounting bracket thereof. Background Art

[0002] Side-scan sonar is a type of ocean detection equipment that uses the principle of echo ranging to measure seabed information and underwater objects by placing directional transducers on both sides. Side-scan sonar systems are generally towed and consist of three parts: a towed body (towfish), a data cable, and a control device. During the scanning operation, the mother ship tows the towfish in the sea water, generating a fan-shaped beam perpendicular to the heading on each side of the towfish, forming a narrow trapezoidal footprint centered on the transducer. When the sound wave encounters an object in the water or hits the seabed, it is backscattered and transmitted back to the transducer. The sound signal is converted into an electrical signal by the transducer, which is filtered and displayed and stored. The amplitude of the signal fluctuation reflects the seabed undulations and geological conditions.

[0003] The Chinese utility model patent with announcement number CN207424257U discloses a high-efficiency adaptive aperture side-scan sonar, including a head fairing, a front cabin, a rear cabin, and a tail shell; the front end of the front cabin is provided with a head fairing, and the front and rear ends of the rear cabin are respectively sealed and screwed through sealing baffles I and sealing baffles II; the rear end of the front cabin is screwed with sealing baffle I; the rear end of the sealing baffle II is screwed with the tail shell, and the front and rear cabins are provided with towing frames and towing plates; the front cabin is equipped with a transmitting array and a receiving array; the rear cabin is provided with an electronic cabin, and the electronic cabin is provided with a transmitter, a receiver, a power module, and a motion information fusion module.

[0004] At present, towed side-scan sonars generally use data cables as towing cables. Data cables are used not only as cables for power supply and data transmission, but also as cables for towing force. Although data cables are specially designed for special use, in traditional towing methods, the marine environment in which the towed body is located for a long time is complex and harsh. During service, there is a possibility of partial tearing or breaking of the data cable, which may cause the towed body to be separated and lost. The value of the towed body is high, and the salvage cost is also high, which invisibly increases the cost of the enterprise. Utility Model Content

[0042] In the utility model, the side scan sonar is a marine detection device that measures seabed information and underwater objects by arranging directional transducers on both sides and using the principle of echo ranging. The side scan sonar system is generally towed, and consists of three parts: a towed body (towfish), a data cable and a control device. During the scanning operation, the mother ship tows the towfish to sail in the sea water, and a fan-shaped beam perpendicular to the heading is generated on both sides of the towfish, forming a narrow trapezoidal footprint centered on the transducer. After the sound wave encounters an object in the water or hits the seabed, it is transmitted back to the transducer due to backscattering. The sound signal is converted into an electrical signal by the transducer, which is displayed and stored after filtering. The signal fluctuation amplitude reflects the seabed undulations and geological conditions.

[0043] In the utility model, the side-scan sonar and the cables used in conjunction with it are both commercially available products.

[0044] In a specific implementation, the accessories of the mounting bracket are all made of metal materials, preferably corrosion-resistant and weather-resistant materials, and a corrosion-resistant coating is applied on the surface to meet the use requirements of the ocean. It can also be made of high-strength engineering plastics. The service life of the mounting bracket can be increased.

[0046] Specifically, the overall shape of the fixing seat is like a channel steel structure, including a bottom plate and webs on both sides, and two ear plates with hinge holes are welded on the other side surface of the bottom plate to form a hinged portion.

[0047] like Figure 4 As shown, the drag plate is fixedly sleeved with a round tube 221, and a threading channel 223 for the cable to pass through is formed between the round tube and the drag plate. Through this design, the threading channel has the function of protecting the cable end and laying the cable to a certain extent.

[0052] An electric winch 30, wherein the electric winch is provided with a steel wire rope 31, and the steel wire rope is connected to the hanging hole of the towing board;

[0053] The cable reel 40 is provided with a cable 41 , and the cable is connected to the towing body.

[0054] In the utility model, the side scan sonar is a marine detection device that measures seabed information and underwater objects by arranging directional transducers on both sides and using the principle of echo ranging. The side scan sonar system is generally towed, and consists of three parts: a towed body (towfish), a data cable and a control device. During the scanning operation, the mother ship tows the towfish to sail in the sea water, and a fan-shaped beam perpendicular to the heading is generated on both sides of the towfish, forming a narrow trapezoidal footprint centered on the transducer. After the sound wave encounters an object in the water or hits the seabed, it is transmitted back to the transducer due to backscattering. The sound signal is converted into an electrical signal by the transducer, which is displayed and stored after filtering. The signal fluctuation amplitude reflects the seabed undulations and geological conditions.

[0055] In the utility model, the side-scan sonar and the supporting cables, electric winches, cable reels, etc. are all commercially available products.

[0056] In a specific implementation, two groups of handles are provided on the upper surface of the towing body, and the two groups of handles are spaced apart from each other, and each group of handles includes two handles that are tilted to the left and right, respectively.

[0057] In a specific implementation, the electric winch is selected from the E-9500 electric winch, which drives the motor to drive the winch by obtaining power from the ship itself.

[0061] The main innovation of the utility model is that it provides a mounting bracket that can assist in the installation of a steel wire rope, thereby realizing an installation structure in which the side-scan sonar towing body can be connected to an external steel wire rope for independent towing operations, and the mounting bracket does not affect the connection between the cable and the towing body. Under this design, the steel wire rope of the electric winch serves as the main element for pulling operations. The strength and tensile properties of the steel wire rope are much higher than those of the towing cable, and it has lower fatigue properties. It can maintain its performance during long-term and high-frequency use, thus reducing the risk of loss of the towing body and reducing corporate losses. The cable in the cable reel also has certain pulling properties and can be used as a secondary pulling rope to cooperate with the steel wire rope to reduce the possibility of loss of the towing body.

[0062] On the other hand, the design of the towing plate with hanging holes allows you to choose the appropriate connection method according to specific needs. For example, you can install it directly on a surveying vessel or an unmanned ship through other mounting components to adapt to different installation scenarios. This flexibility makes the mounting bracket widely used in various side scan sonar installation environments.

[0063] On the other hand, the dragging plate is hinged and can swing within a certain range, and the angle between the dragging body and the mounting bracket can be flexibly adjusted, which makes the dragging operation of the wire rope more flexible and meets the needs of the dragging body operation. The overall structural design of the mounting bracket is simple and can be adapted to most dragging bodies, with strong practical performance.

[0064] In a preferred embodiment, a hook is provided at the end of the steel wire rope, and the hook is hooked to the hanging hole of the towing plate. The hook facilitates the quick assembly and disassembly of the steel wire rope and the towing body.

[0065] like Figure 4 As shown, the connecting seat is a channel steel structure, and the two webs of the connecting seat are provided with a plurality of through holes arranged along the same straight line, and the through holes of the two webs are arranged correspondingly; the fixed seat is a channel steel structure adapted to the connecting seat, and the fixed seat is sleeved on the connecting seat from top to bottom, and the two webs of the fixed seat are provided with bolt holes corresponding to the through holes.

[0066] Through this design, the entire mounting bracket can be easily installed. Specifically, the connecting seat is a supporting structure of most drag bodies. It can also be assembled on the outer shell of the drag body by later welding or other methods.

[0067] For other structures of a ship-borne side-scan sonar and its mounting bracket described in this embodiment, refer to the prior art.

[0068] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention.
